Technical Field

The present invention relates to a cleaning tool capable of removing dust and the like on the surface of an object to be cleaned by the adhesive force of an adhesive tape roller.

Background

Conventionally, various structures have been proposed as cleaning tools. For example, japanese patent application laid-open No. 2016 and 41219 describes a cleaning tool having a detachable grip portion (handle) so as to be compact when displayed for sale or the like.

Disclosure of Invention

Problems to be solved by the invention

However, in such a configuration, when the handle portion is separated from the main body of the cleaning tool, there is no physical relationship between the handle portion and the main body, and therefore, there is a possibility that the handle portion is not disposed at a fixed position, and stable packaging cannot be performed.

Accordingly, an object of the present invention is to provide a cleaning tool that can be stably packaged and can be compactly displayed when sold.

Means for solving the problems

The present invention is a cleaning tool, comprising: a cleaning tool body having an adhesive tape roller; and a case that houses at least the adhesive tape roller in the cleaning tool main body, the cleaning tool main body including: a roller support portion that rotatably supports the adhesive tape roller; and a handle which is used in a state of being connected to the roller support portion when cleaning is performed, wherein the case has an opening portion through which the adhesive tape roller passes when stored, the handle is separated from the roller support portion at least before use of the cleaning tool body is started, and the case has a handle holding portion for holding the handle separated from the roller support portion.

According to this aspect, the handle is held by the handle holding portion in the case, so that the case and the handle can have a physical relationship. Therefore, the handle separated at the time of display can be prevented from being scattered with respect to the box body.

In the cleaning tool, the handle holding portion may face an outer surface or an inner surface of the case.

According to this aspect, the handle can be held so as to face the outer surface or the inner surface of the box body. Therefore, the distance between the box body and the handle can be reduced. Thus, the case can be made compact with the handle held.

In addition, the cleaning tool may be configured such that the roller support portion includes: a1 st portion extending in parallel with a longitudinal direction of the adhesive tape roller; and a2 nd portion which is continuous with the 1 st portion and supports at least one end portion of the adhesive tape roller in a longitudinal direction thereof, wherein the handle extends in a direction intersecting the longitudinal direction of the adhesive tape roller with respect to the 1 st portion in a state of being connected to the roller support portion, a housing is formed by attaching the roller support portion to the case in a state of being separated from the handle and holding the handle in the handle holding portion, and when the housing is disposed with the opening portion facing upward, an upper mounting region constituting an upward surface and a lower mounting region constituting a downward surface are formed in the housing, and a vertical dimension between an uppermost end and a lowermost end of a portion other than the upper mounting region and the lower mounting region of the housing is equal to a vertical dimension between the upper mounting region and the lower mounting region, or a vertical dimension between uppermost and lowermost ends of a portion of the upper and lower receiving regions of the receiving body other than the upper and lower receiving regions is smaller than a vertical dimension between the upper and lower receiving regions.

According to this aspect, when the plurality of containers are to be stacked in the vertical direction, the upper loading area of the lower container and the lower loading area of the upper container do not float, and therefore the plurality of containers can be reliably stacked in the vertical direction.

In addition, in the cleaning tool, when the housing is disposed so that the opening faces upward, the upper surface of the 1 st portion may be a flat surface, and when a plurality of the housings are stacked in the vertical direction, the lower placement region of another housing may be in contact with the upper surface.

According to this aspect, the plurality of containers can be stacked upward via the plane, and therefore the stacking of the plurality of containers is stable.

In the cleaning tool, a height of a peripheral edge portion of the opening in the housing may be substantially equal to a height of an upper surface of the 1 st portion.

According to this embodiment, the upper mounting region is formed by both the peripheral edge of the opening and the upper surface of the 1 st portion, and the upward surface of the upper mounting region is substantially flat. Therefore, the stacking of the plurality of containers is stable.

In the cleaning tool, the roller support portion in a state of being separated from the handle is attached to the case, and the handle is held by the handle holding portion, thereby forming a housing, the opening portion is provided along a longitudinal direction of the adhesive tape roller housed in the case, and the handle holding portion is provided inside the case and is positioned closer to the opening portion than a radial center of the adhesive tape roller in the housing.

According to this aspect, when the cross-sectional shape of the adhesive tape roller is substantially circular, there is a space in the case at a position closer to the opening than the radial center of the adhesive tape roller, so as to prevent the adhesive tape roller from being obstructed from passing through. By using this space as the handle holding portion, the internal space of the case can be effectively utilized.

In addition, the cleaning tool may be configured such that the handle holding portion is provided inside the case, and the roller supporting portion includes: a1 st portion extending in parallel with a longitudinal direction of the adhesive tape roller; and a2 nd portion which is continuous with the 1 st portion and supports at least one end portion of the adhesive tape roller in the longitudinal direction, wherein the roller support portion is attached to the case, and in this state, the 1 st portion covers a part of the opening, and the width dimension of each of the portions not covered by the 1 st portion in the opening is smaller than the radial dimension of the handle.

According to this aspect, the width dimension of each of the portions of the opening portion not covered by the 1 st portion is smaller than the radial dimension of the handle, and therefore, the handle can be prevented from passing through the opening portion covered by the 1 st portion. Therefore, the handle held by the handle holding portion inside the box body can be prevented from falling outside the box body even if the box body is turned upside down.

In the cleaning tool, the handle holding portion may be provided inside the case, at least 1 handle may be held in the case, and the total length of the handle may be 90% or more and less than 100% of the inner dimension of the case in the longitudinal direction.

According to this technical scheme, the inner dimension of the box in the long side direction is substantially equal to the total length of the handle. Therefore, the handle held by the handle holding portion inside the box body is not easily shaken and can be stably held.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the present invention, since the box body and the handle can be physically associated with each other, it is possible to prevent the handle separated at the time of display from being scattered with respect to the box body. Therefore, the cleaning tool can be stably packaged and compactly displayed at the time of sale or the like.

Detailed Description

Next, the present invention will be described by taking an embodiment. The vertical direction in the following description corresponds to the vertical direction shown in fig. 1 and 2. In the case 3, the direction facing the space is inward and the direction not facing the space is outward with respect to the space where the adhesive tape roller 21 is held as a reference. The same is true for the "inner surface" and the "outer surface". However, the direction in carrying out the present invention is not limited to the direction described below.

The cleaning tool 1 of the present embodiment includes: a cleaning tool body 2 having a cylindrical adhesive tape roller 21 (hereinafter, simply referred to as a "roller"); and a case 3 that houses at least the roller 21 in the cleaning tool body 2. Fig. 1 shows a form of the cleaning tool 1 after the cleaning tool body 2 is started to be used, and fig. 2 shows a form of the cleaning tool 1 at least before the cleaning tool body 2 is started to be used (for example, when displayed for sale or the like). In fig. 2, a packaging material for packaging the container 1A (described later) which is a combination of the cartridge 3, the roller support portion 22, and the handle 23 is not shown.

The cleaning tool body 2 is in the form shown in fig. 3. The cleaning tool body 2 includes: a roller support portion 22 that supports the roller 21 so that the roller 21 can rotate in the circumferential direction; and a handle 23 formed separately from the roller support portion 22 and used in a state of being connected to the roller support portion 22 when cleaning is performed. The handle 23 is a portion to be held by a user when cleaning is performed. Fig. 4 shows a form of the roller support portion 22, and fig. 5 shows a form of the handle 23.

The roller 21 can be a roller having a known structure. The roller 21 can expose the outer peripheral surface having adhesive force by peeling off the release paper, and can remove dust and the like by adhering the dust and the like to the outer peripheral surface by rolling the outer peripheral surface on the surface of an object to be cleaned such as a floor surface of a house, thereby cleaning the object to be cleaned.

The roller support portion 22 includes: a base 221 as a part 1 extending in parallel with the longitudinal direction of the roller 21; and a branch portion 222 as a2 nd portion that is continuous with the base portion 221 and supports at least one end portion in the longitudinal direction of the roller 21. The structure of the roller support portion 22 is not limited to this, and various structures can be provided.

The base 221 is formed with a plurality of ribs 2211 extending in the longitudinal direction on the side opposite to the roller 21 (the lower side when stored in the case 3), whereby the bending in the longitudinal direction is reinforced. The side of the base 221 opposite to the roller 21 (the upper side when stored in the case 3) is set to be a flat surface. When the containers 1A, which are a combination of the cartridges 3, the roller support portions 22, and the handles 23, are stacked vertically, the lower edge of the cartridge 3 in the upper container abuts on the upper surface 2212, which is the flat surface. A cylindrical handle connecting portion 2213 is provided in the base portion 221, and the handle connecting portion 2213 faces the side opposite to the roller 21 (see fig. 7). The handle connecting portion 2213 of the present embodiment is embedded in the base portion 221, and the inner peripheral surface of the handle connecting portion 2213 appears as a handle connecting hole 2214 on the surface of the base portion 221 (see fig. 2 and 4). In the present embodiment, since the cross-sectional shape of the handle 23 is circular, the handle attachment hole 2214 is formed as a circular hole. The distal end portion of the handle 23 can be inserted into the handle attachment hole 2214. The fitting claw 231 formed at the distal end portion of the handle 23 is fitted to the lower edge of the handle connecting portion 2213. Thereby, the handle 23 is fixed to the base 221 so as not to be easily pulled out.

The branch portion 222 is a plate-like portion protruding from both ends in the longitudinal direction of the base portion 221 in one direction intersecting the base portion 221. As shown in fig. 3 and 4, a substantially disc-shaped roller mounting portion 24 is provided at the distal end of the branch portion 222 so as to be rotatable with respect to the branch portion 222. As shown in fig. 8, the roller mounting portions 24 are fitted into the open ends of the roller 21. A cylindrical protrusion 241 protrudes in one direction from the radial center of the roller mounting portion 24. In the present embodiment, a circular through hole 2222 that penetrates in the thickness direction of the branch portion 222 (that coincides with the longitudinal direction of the roller 21) is provided, and the protrusion 241 of the roller mounting portion 24 penetrates the through hole 2222, so that the columnar protrusion 241 can rotate relative to the through hole 2222. Thereby, the roller 21 is rotatable with respect to the roller support portion 22. When the projection 241 of the roller mounting portion 24 is inserted through the through hole 2222 of the branch portion 222, the opposed branch portion 222 is bent in a direction to enlarge the gap. The configuration for rotating the roller 21 with respect to the branch portion 222 is not limited to this, and various configurations can be adopted.

As shown in fig. 3, the branch portion 222 has a stepped portion 2221 in the thickness direction, and is formed thick on the radial inner side and thin on the radial outer side with the stepped portion 2221 as a boundary. The roller holder 22 can be attached to the cartridge 3 by fitting the stepped portion 2221 to an insertion groove 33 formed in the cartridge 3 in the vertical direction. In a state where the roller support portion 22 is attached to the case 3, a part (thick portion) of the branch portion 222 in the thickness direction enters the insertion groove 33, and the other part (thin portion) covers the portion around the insertion groove 33 of the outer surfaces of both ends of the case 3 in the longitudinal direction.

The handle 23 has a structure as shown in fig. 5, and is formed in a straight bar shape having a circular cross-sectional shape. The handle 23 is separated from the roller support portion 22 at least before the cleaning tool body 2 is used, and in the present embodiment, the handle 23 is held by the handle holding portion 4 provided inside the case 3. The handle 23 has a distal end portion connectable to the handle connecting portion 2213 of the roller support portion 22. The handle 23 extends in a direction intersecting the longitudinal direction of the roller 21 with respect to the base 221 of the roller support portion 22 in a state of being connected to the roller support portion 22. In the present embodiment, the handle 23 protrudes from the center of the base 221 in the longitudinal direction so as to be orthogonal to the base 221.

As described above, since the fitting claw 231 of the lever 23 is fitted to the lever connecting portion 2213 of the roller support portion 22, the lever 23 is not easily detached once it is connected to the roller support portion 22. That is, after the cleaning tool body 2 is started to be used, the handle 23 and the roller support portion 22 are maintained in a connected state.

The distal end portion of the handle 23 is provided with a projection 232 for positioning with respect to the handle attachment hole 2214 in addition to the fitting claw 231. On the other hand, a groove 2215 is formed in a portion of the inner surface of the handle connecting portion 2213 corresponding to the projection 232. By combining the projection 232 and the groove 2215 for positioning, the user can easily attach the handle 23 to the roller support 22 at home or the like before using the cleaning tool 1 (cleaning tool body 2).

As shown in fig. 6, the case 3 is formed in a substantially rectangular parallelepiped shape. The longitudinal direction of the cartridge 3 coincides with the longitudinal direction of the roller 21, and the width direction of the cartridge 3 coincides with the radial direction of the roller 21. In the present embodiment, the upper surface of the case 3 is open, and is formed as an opening 31 through which the roller 21 passes when stored in the case 3. Therefore, the opening 31 is provided along the longitudinal direction of the roller 21 housed in the case 3. The opening 31 has a substantially rectangular shape in plan view. The outer surface (side surface) of the long side of the case 3 is curved downward and has a shape in which a portion in the width direction is enlarged. Therefore, the shape of the sheet is enlarged downward, and therefore, the sheet can contribute to stability when placed. As shown in fig. 7, a bottom portion (lower portion) 32 of the cassette 3 is curved so as to match the outer peripheral surface of the lower half of the housed roller 21, and has a semicircular longitudinal section. The inner surface of the bottom portion 32 is provided at a position spaced apart from the outer peripheral surface of the roller 21 in the accommodated state, and it is possible to avoid difficulty in taking out the roller 21 from the cartridge 3 due to the adhesive force of the roller 21. Insertion grooves 33 are formed at both ends in the longitudinal direction of the case 3, and the insertion grooves 33 are opened upward and closed downward and extend in the vertical direction. The insertion groove 33 is provided at the center in the width direction and penetrates in the thickness direction (the longitudinal direction of the case 3). The branch portion 222 of the roller support portion 22 can be attached to the insertion groove 33. The width of the upper portion of the insertion groove 33 is enlarged and opened at the upper edge of the case body 3. Therefore, the roller support portion 22 can be easily attached to the insertion groove 33.

The case 3 of the present embodiment is configured to be able to house the roller 21 and to hold the handle 23. Therefore, the cartridge 3 has the handle holding portion 4 for holding the handle 23 separated from the roller bearing portion 22. Here, the term "hold" means that there is a relationship between the case 3 and the handle 23 to the extent that the handle 23 does not become free from the case 3. For example, in the present embodiment, the handle holder 4 is a space between the outer peripheral surface of the roller 21 and the opening 31 of the case 3 in the case 3. Therefore, for example, when the case 3 is tilted, the degree of movement of the handle 23 in the range of the space is allowed as the holding state.

The handle holding portion 4 of the present embodiment is provided inside the case 3, and is located closer to the opening 31 than the center in the radial direction of the roller 21 in the state of the container 1A. In the present embodiment, the space that is located diagonally above the outer peripheral surface of the roller 21 with respect to the center of the roller 21 as shown in fig. 7 corresponds to the handle holding portion 4. The handle 23 is held by abutting against the outer peripheral surface of the roller 21 and the inner surface of the case 3 in the width direction. When the handle 23 is held in this manner, the cleaning tool body 2 is in a state before the start of use, and therefore the outer peripheral surface of the roller 21 is covered with the release paper, and the handle 23 does not stick to the roller 21. The handle 23 is restricted from moving in the longitudinal direction in the handle holding portion 4 by the inner surfaces of both ends in the longitudinal direction of the case 3. Here, in the case where the cross-sectional shape of the roller 21 is substantially circular, a space is required in the case 3 at a position closer to the opening 31 than the radial center of the roller 21 in order to prevent interference with the passage of the roller 21 at the time of storage or removal. By using this space as the handle holding portion 4, the internal space of the case 3 can be effectively utilized.

The handle 23 is placed only on the handle holding portion 4 of the present embodiment, and is set in a state where the handle 23 is allowed to move in the handle holding portion 4. However, the present invention is not limited to this, and the handle 23 may be fixed to the case 3 so as to be immovable in the handle holding portion 4.

By holding the handle 23 by the handle holding portion 4 in the case 3, the case 3 and the handle 23 can have a physical relationship. Therefore, the handle 23 separated at the time of display can be prevented from being scattered with respect to the box body 3. The handle holding portion 4 of the present embodiment faces the inner surface of the case 3. With this structure, the handle 23 can be held facing the inner surface of the case 3. Therefore, the distance between case 3 and handle 23 can be reduced as compared with the case where handle holder 4 is provided at a position away from the inner surface of case 3. Therefore, a space dedicated to holding the cartridge 3, which is not used as a space through which the roller 21 passes when, for example, storing or taking out the cartridge, can be eliminated, and therefore the cartridge 3 can be made compact while holding the handle 23.

The housing 1A is formed by attaching the roller support portion 22 in a state separated from the handle 23 to the case 3 and holding the handle 23 on the handle holding portion 4. In the present embodiment, since the handle holding portion 4 is provided inside the case 3, the handle 23 can be prevented from protruding from the case 3 in the housing 1A. The container 1A obtained by combining the case 3, the roller support portion 22, and the handle 23 in this manner can be entirely wrapped with a packaging material such as a sheet or a bag made of resin, which is not shown. The containers 1A thus packaged can be displayed in a place such as a storefront alone or stacked one on top of another. Since the cleaning tools can be stacked vertically in this manner, even in a store with limited display space, a plurality of cleaning tools can be displayed in the state of the storage body 1A, which is advantageous.

In the housing 1A, the opening 31 is disposed facing upward, and in this case, the upper placement region 1A1 constituting an upward surface and the lower placement region 1A2 constituting a downward surface are formed in the housing 1A. The vertical dimension between the uppermost end and the lowermost end of the portion other than the upper loading region 1A1 and the lower loading region 1A2 of the storage body 1A is set to be equal to the vertical dimension between the upper loading region 1A1 and the lower loading region 1A2 or smaller than the vertical dimension between the upper loading region 1A1 and the lower loading region 1A 2. According to this configuration, when the plurality of containers 1A … 1A are to be stacked in the vertical direction, the upper loading region 1A1 of the lower container 1A reliably contacts the lower loading region 1A2 of the upper container 1A without floating, and therefore, as shown in fig. 9, a plurality of (two in the figure) containers 1A … 1A can be reliably stacked in the vertical direction.

In the present embodiment, the upper surface 2212 of the base portion 221 of the roller support portion 22 is a flat surface without a protruding portion. Therefore, when the opening 31 is arranged to face upward in the housing 1A, and when a plurality of housings 1A … 1A are stacked in the vertical direction, the lower receiving area 1A2 of another housing 1A comes into contact with the upper surface 2212 of the base portion 221. With this configuration, since the plurality of housings 1A … 1A can be stacked in a plane upward, as shown in fig. 9, the stacking of a plurality of (two in the figure) housings 1A … 1A is stable.

In the present embodiment, the height of the peripheral edge portion of the opening 31 in the housing 1A is substantially equal to the height of the upper surface 2212 of the base portion 221 in the roller support portion 22. Preferably, the height of the peripheral edge portion of the opening 31 is equal to the height of the upper surface 2212 of the base portion 221 in the roller support portion 22. However, in practice, as shown in fig. 9, it is also possible to construct the upper surface 2212 of the base portion 221 so as to be slightly higher. According to this configuration, the upper mounting region 1a1 is configured by both the peripheral edge of the opening 31 and the upper surface 2212 of the base portion 221, and the upward surface of the upper mounting region 1a1 is substantially flat. Therefore, as shown in fig. 9, the stacking of the plurality of (two in the figure) housings 1A … 1A is stable.

The roller support portion 22 is attached to the cartridge 3, and in this state, the base portion 221 of the roller support portion 22 covers a part of the opening 31 of the cartridge 3. Therefore, opening 31 is divided into two portions and remains between both width-direction end edges of base 221 and both width-direction end edges of opening 31 of case 3. The width dimension of each of the remaining portions of the openings 31, i.e., the portions of the openings 31 of the case 3 not covered by the base 221, is set smaller than the radial dimension of the handle 23. In this configuration, the width dimension of each of the portions of the opening 31 not covered by the base portion 221 of the roller support portion 22 is smaller than the radial dimension of the handle 23, and therefore, the handle 23 can be prevented from passing through the opening 31 covered by the base portion 221. Therefore, even when the case 3 is turned upside down and the opening 31 faces downward, the handle 23 held by the handle holding portion 4 inside the case 3 can be prevented from falling outside the case 3. Further, since the roller 21 after the start of use is covered with the base portion 221 of the roller support portion 22, the base portion 221 is a "shielding portion", and the roller 21 to which dust and the like adhere is not easily visible, and therefore, the uncomfortable feeling to the user can be suppressed, which is advantageous.

In addition, at least 1 handle 23 is held in the case 3. The number of the handles 23 held in this embodiment is 1. When the plurality of handles 23 are held, the plurality of handles 23 are formed to be connectable, and a cleaning tool having a long handle 23 can be provided. The handle 23 is long, which is advantageous in that it is easy to use when cleaning. The total length of the held 1 handle 23 is preferably 90% or more and less than 100% of the total length of the handle 23 with respect to the inner dimension of the case 3 in the longitudinal direction. By setting the overall length to this value, the inner dimension of the case 3 in the longitudinal direction can be made substantially equal to the overall length of the handle 23. Therefore, the handle 23 held by the handle holding portion 4 inside the case 3 is less likely to be shaken, and the handle 23 can be stably held. The overall length of the handle 23 may be less than 90%, but the length is too short relative to the case 3, and when the handle holding portion 4 is provided inside the case 3, the gap in the longitudinal direction of the handle 23 becomes large. If the amount is 100% or more, the handle 23 cannot be accommodated in the case 3 when the handle holding portion 4 is provided inside the case 3, which is not preferable. Further, in the case where the handle holding portion 4 is provided outside the case 3, the handle 23 can be held, but the handle 23 is not preferable because it protrudes in the longitudinal direction from the case 3.

While one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the present invention.

For example, the roller support portion 22 of the above embodiment is in a "both-end holding" form in which the branch portions 222 protrude from both ends of the base portion 221. However, the present invention is not limited to this, and may be "one-end holding" in which only one end of the roller 21 is supported.

In addition, the handle 23 of the embodiment has a circular cross-sectional shape. However, the present invention is not limited to this, and may be polygonal or other geometric shapes. The cross-sectional shape may be a flat shape. Further, the size and the cross-sectional shape may be different in the longitudinal direction. When the handle 23 is formed in these shapes, the "radial dimension" of the handle 23 is evaluated by the width dimension of the projected shape when the projected area of the handle 23 in the direction orthogonal to the longitudinal direction is the smallest. If the width of each of the portions of opening 31 of case 3 not covered by base 221 is set smaller than the above width, handle 23 is caught, and thus, handle 23 can be prevented from falling to the outside of case 3, as in the above embodiment.

In addition, the handle 23 of the above embodiment is configured so that it cannot be easily detached once it is connected to the base 221. However, for example, the handle 23 may be easily detachable so that the handle 23 can be connected only when used at home and the handle 23 can be detached when stored.

The shape of the case 3 is merely an example, and various shapes can be provided. The opening 31 of the case 3 may be in the form of a side opening of the case 3. In this case, the cleaning tool body 2 may be configured such that the handle 23 protrudes in the axial direction with respect to the roller 21 (configured such that the handle 23 coincides with the axial center of the roller 21).

In addition, the handle holding portion 4 of the embodiment faces the inner surface of the case 3. However, the present invention is not limited to this, and the handle holding portion 4 may be formed so that the handle holding portion 4 faces the outer surface of the case 3. In this case, the handle 23 can be held by, for example, fitting into the recess, hooking by the claw portion, and adhering by a double-sided adhesive tape.

In addition, when the handle holding portion 4 is formed so that the handle holding portion 4 faces the outer surface of the case 3, a space 4X between the bottom portion 32 of the case 3 and the lower end of the case 3, as shown in fig. 7, for example, can be used as the handle holding portion 4.

Further, the handle 23 can be placed from above so that a part of the handle 23 fits into the remaining opening portion in a state where the base portion 221 of the roller support portion 22 covers a part of the opening portion 31 of the cartridge 3. In this case, the remaining portion of the opening 31 serves as the handle holding portion 4.

Further, the inside of the roller 21 may be the handle holding portion 4, and the separate handle 23 may be accommodated therein.

Further, the handle 23 may be housed in the roller support portion 22 by providing the handle holding portion 4 between the base portion 221 and the roller 21.

In addition, when the storage body 1A is disposed so that the opening 31 faces upward, a columnar connected portion to which the handle 23 is connected can be projected from the upper surface 2212 of the base portion 221, which is not illustrated. In this case, a recess into which the connected portion of another housing 1A enters when a plurality of housings 1A … 1A are stacked in the vertical direction is formed in the lower portion (bottom portion 32) of the box 3. The recess is formed in a size that can be entered by the connecting portion. Thus, even if the connected portion protrudes from the base portion 221, the lower placement region 1A2 of the upper housing 1A does not float with respect to the upper placement region 1A1 of the lower housing 1A. In addition, the connected portion (together with the handle 23) may be held by the user in a state where the handle 23 is attached.
