Further, the cover member 24 includes: an elastic piece 24d projecting downward from the lower surface of the rear side, and a locking claw 24e projecting forward from the tip of the elastic piece 24 d. On the other hand, a locking hole 22e is provided on the rear side opening of the cover member 22. In a state where the elastic piece 24d is inserted into the locking hole 22e, the locking claw 24e is locked to the locking hole 22e, whereby the cover member 24 is restricted from rotating (moving) upward relative to the cover member 22.

As shown in fig. 2 to 6 and 9, the middle plug 12 is attached to the cover body 10 so as to be movable in the vertical direction.

Specifically, the middle pin 12 includes a pin body 29, a slide shaft 30, a second coil spring 31, and a second holding member 32. The second coil spring 31 is made of a metal wire material having excellent corrosion resistance, such as stainless steel, as the second biasing member. The plug 29, the slide shaft 30, and the second holding member 32 are made of a resin molded body such as PP, ABS, POM, or the like.

The plug body 29 is formed in a substantially circular plate shape as a whole so as to close the lower side of the lid main body 10. The plug 29 has a shape recessed upward. Further, a pair of wall portions 29a for grasping at the time of attachment and detachment are provided so as to protrude downward from positions facing each other at outer peripheral portions on the lower surface side of the plug body 29.

A sleeve portion 33 is provided at the center of the plug 29. The sleeve portion 33 is a portion that axially supports the slide shaft 30 so as to be slidable in the vertical direction, has a center hole 33a penetrating the plug body 29, and is provided to protrude upward in a substantially cylindrical shape. The sleeve portion 33 is disposed inside the second coil spring 31.

The slide shaft 30 has a shaft portion 30a and a head portion 30b provided at a lower end portion of the shaft portion 30a, and is attached to the plug body 29 so as to be slidable (movable) in the vertical direction in a state where the shaft portion 30a penetrates the center hole 33a toward the upper side. Further, the head 30b of the slide shaft 30 abuts against the lower surface of the plug 29, thereby restricting the slide (movement) of the slide shaft 30 upward relative to the plug 29.

The slide shaft 30 has a plurality of (4 in the present embodiment) rib walls 30c protruding from the periphery of the shaft portion 30a on the proximal end side. On the other hand, a plurality of (4 in the present embodiment) guide grooves 33b into which the plurality of rib walls 30c engage are provided on the inner side of the sleeve portion 33 (the inner circumferential surface of the center hole 33 a). Thereby, the rotation of the plug body 29 about the axis with respect to the shaft portion 30a (the slide shaft 30) is regulated in the middle plug 12.

Further, the shaft portion 30a is provided on its outer peripheral surface with a pair of screw engagement grooves 30d to which the pair of screw engagement projections 27b are screw-engaged, and a pair of locking grooves 30e to which the pair of screw engagement projections 27b are locked. The pair of screw engagement grooves 30d are formed by spirally cutting from the upper end side of the shaft portion 30a downward. The pair of locking grooves 30e are formed continuously with the lower end portions of the respective screw engagement grooves 30d and are notched upward.

A shaft liner 34 is detachably attached to the shaft 30 a. The shaft portion packing 34 is an annular seal member that seals a space between the shaft portion 30a (the slide shaft 30) penetrating the shaft hole 19a of the sleeve portion 19 and the shaft hole 19a (the cap body 10), and is made of, for example, an elastic member such as a heat-resistant rubber or elastomer such as silicone rubber.

The shaft portion packing 34 is fitted into an annular fitting recess 30f provided on the outer peripheral surface of the shaft portion 30 a. An elastic flange portion 34a that closely contacts the periphery of the shaft hole 19a over the entire periphery is provided on the outer peripheral surface of the shaft portion packing 34 so as to protrude in the diameter expansion direction.

A head gasket 35 is detachably attached to the head 30 b. The head packing 35 is an annular seal member that seals between the head 30b (the slide shaft 30) that is in contact with the periphery of the center hole 33a of the sleeve portion 33 and the center hole 33a (the plug 29), and is made of, for example, an elastic member such as a heat-resistant rubber such as silicone rubber or an elastic body. The head pad 35 covers the outer periphery of the head 30 b.

The second holding member 32 has: a substantially circular top wall portion 32a, a peripheral wall portion 32b that descends substantially cylindrically from the outer periphery of the top wall portion 32a, and a slide hole 32c that penetrates the center portion of the top wall portion 32 a.

The second coil spring 31 is compressed between the plug 29 and the top wall portion 32a, and the shaft portion 30a is inserted into the slide hole 32c, whereby the second holding member 32 is attached to the slide shaft 30.

Further, the second holding member 32 is in contact with the contact portion 30g provided between the upper end portions of the plurality of rib walls 30c, thereby being restricted from sliding (moving) upward relative to the slide shaft 30.

Thereby, the second holding member 32 holds the second coil spring 31 in a compressed state between the second holding member and the plug 29. The second holding member 32 is slidable (movable) in the vertical direction in a state biased upward by the second coil spring 31. The second coil spring 31 biases the plug 29 downward with respect to the slide shaft 30.

Further, a plurality of (4 in the present embodiment) guide grooves 32d into which the plurality of rib walls 30c are engaged are provided on the inner peripheral surface of the slide hole 32 c. Thus, the rotation of the second holding member 32 about the axis with respect to the shaft portion 30a (the slide shaft 30) is regulated in the plug 12.

In the cover unit 3 of the present embodiment, as shown in fig. 2, 3, 6, and 10, the slide shaft 30 on the side of the middle plug 12 is detachably attached to the first holding member 23 on the side of the cover 11 by screwing.

Specifically, the slide shaft 30 (the middle bolt 12) is detachably attached to the first holding member 23 (the cover body 11) by screwing in a state in which the shaft portion 30a of the slide shaft 30 penetrates the shaft holes 19a, 22b, and 27a provided in the cover body 10, the cover member 22, and the first holding member 23, and the tip portion of the shaft portion 30a protrudes upward from the first holding member 23.

The middle plug 12 can be attached to the first holding member 23 (the cover 11) by screwing the pair of screw engagement projections 27b into the pair of screw engagement grooves 30d while rotating the slide shaft 30 and the plug body 29 integrally in one direction about the shaft (in the present embodiment, right-hand winding), and then locking the pair of screw engagement projections 27b into the pair of locking grooves 30 e.

Thus, in the cover unit 3 of the present embodiment, the cover body 11 and the middle plug 12 can be attached to the cover main body 10. In the cover unit 3 of the present embodiment, the plug 29 is closely attached to the water-stop packing 20 over the entire circumference, and the lower side of the cover body 10 is closed by the plug 29 (the middle plug 12).

On the other hand, the slide shaft 30 is pivoted about the shaft (left-hand pivot in the present embodiment) in the opposite direction to the one direction integrally with the plug body 29, whereby the middle plug 12 can be removed from the first holding member 23 (cover body 11). Thus, in the cover unit 3 of the present embodiment, the cover body 11 and the middle plug 12 can be detached and disassembled from the cover main body 10.

As shown in fig. 11 and 12, the lid unit 3 of the present embodiment includes a stopper mechanism 36 that restricts the pivotal movement of the plug body 29 (the middle plug 12) with respect to the lid main body 10 in a state where the plug body 29 (the middle plug 12) closes the lower portion side of the lid main body 10.

The stopper mechanism 36 has: at least one or a plurality of (two in the present embodiment) locking portions 36a provided on the surface (upper surface) side of the plug body 29 facing the cap body 10, and at least one or a plurality of (two in the present embodiment) engaged portions 36b provided on the surface (lower surface) side of the cap body 10 facing the plug body 29.

The locking portion 36a is formed of a wall portion protruding from the upper surface side of the plug body 29. The locking portion 36a extends in the radial direction of the plug body 29, and is provided so that the upper end thereof protrudes at the same height in the radial direction with respect to the inclined upper surface of the plug body 29. The locking portions 36a are provided at symmetrical positions with respect to the center hole 33a of the plug body 29.

The engaged portion 36b is formed by a groove portion formed by cutting out a part of the lower peripheral wall 10f protruding from the lower surface side of the cover main body 10. One end (left end) of the engaged portion 36b in one direction is formed by a vertical surface, and the other end (right end) is formed by an inclined surface. The locked portions 36b are provided at symmetrical positions with respect to the shaft hole 19a of the cover body 10.

In the stopper mechanism 36, in a state where the plug body 29 (the middle plug 12) closes the lower portion side of the lid main body 10, the locking portion (the wall portion) 36a is locked to the locked portion (the groove portion) 36b, thereby restricting the plug body 29 (the middle plug 12) from pivoting with respect to the lid main body 10.

This prevents the plug 29 (the middle plug 12) from pivoting and the slide shaft 30 (the middle plug 12) from being disengaged from the first holding member 23 (the lid body 11) from screwing when the lid unit 3 is attached to and detached from the container body 2 while pivoting.

On the other hand, in the stopper mechanism 36, in a state where the plug body 29 (the middle plug 12) is opened to the lower side of the cover main body 10, a state where the locking portion (the wall portion) 36a is locked to the locked portion (the groove portion) 36b is released. This allows the plug body 29 (the middle plug 12) to easily pivot with respect to the lid main body 10.

In the stopper mechanism 36, when the plug body 29 (the middle plug 12) is pivoted about the axis with respect to the cover main body 10, the stopper body 29 is separated from the waterproof packing 20 while the locking portion (the wall portion) 36a is in sliding contact with the lower end portion of the lower peripheral wall 10 f. Thereby, the plug body 29 (the middle plug 12) can be easily pivoted with respect to the cover main body 10 so that the plug body 29 (the middle plug 12) does not contact the water seal packing 20.

In the stopper mechanism 36, the structures of the locking portion 36a and the locked portion 36b may be appropriately changed, as long as the locking portion 36a is locked to the locked portion 36b, not limited to the case where the locking portion 36a is formed of a wall portion, and the locked portion 36b is formed of a groove portion.

In the cover unit 3 of the present embodiment having the above-described configuration, the plug body 29 (the middle plug 12) closes the lower portion side of the cover main body 10, thereby closing the flow path R. From this state, the grip portion 8a is held with one hand, and the operation handle 24a is pressed downward by a thumb or the like.

At this time, from the state where the tip end portion of the slide shaft 30 has come into contact with the cover member 24, the cover member 24 (cover 11) is rotated (moved) downward against the biasing force of the first coil spring 21, and the slide shaft 30 (middle pin 12) is slid (moved) downward. Thereby, the plug body 29 (middle plug 12) opens the lower side of the lid body 10, and the flow path R is opened.

When the plug 29 (the middle plug 12) receives the pressure in the container body 2, the sliding shaft 30 (the middle plug 12) slides (moves) downward, so that the head 30b opens the lower side of the center hole 33a against the biasing force of the second coil spring 31, and the inside of the container body 2 is ventilated through the vent hole 18.

In the lid unit 3 of the present embodiment, by tilting the container body 2 forward from this state, the beverage contained in the container body 2 can be poured out from the pouring port 15 through the opened flow path R.

On the other hand, in the cover unit 3 of the present embodiment, the pressing operation of the operation lever 24a is released, and the cover member 24 (cover body 11) biased by the first coil spring 21 is thereby rotated (moved) upward. Further, the slide shaft 30 (the middle pin 12) urged by the first coil spring 21 slides (moves) upward. Thereby, the plug 29 (middle plug 12) closes the lower side of the lid body 10, and the flow path R is closed.

The slide shaft 30 (the middle pin 12) slides (moves) upward, and the head portion 30b biased by the second coil spring 31 closes the lower portion side of the center hole 33 a.

In the cover unit 3 of the present embodiment, the cover member 22 (cover body 11) described above is provided with a flow path forming portion 25 that forms a part of the flow path R. This prevents the beverage in the flow path R from flowing into the inside of the cover 11 (specifically, between the cover member 22 and the cover member 24), and also keeps the flow path R clean.

In the cover unit 3 of the present embodiment, the middle plug 12 is detachable from the cover 11 in a state where the middle plug 12 opens the flow path R. Specifically, in a state where the plug body 29 (the middle plug 12) opens the lower portion side of the lid main body 10, the slide shaft 30 on the middle plug 12 side is detachable from the first holding member 23 on the lid body 11 side by screwing.

Thus, in the lid unit 3 of the present embodiment, the lid body 11 and the middle plug 12 can be removed from the lid body 10 in a state where the plug body 29 (middle plug 12) opens the lower side of the lid body 10, and the lid unit 3 can be easily disassembled.

Therefore, in the cover unit 3, the flow path R can be easily cleaned in a state where the cover main body 10, the cover body 11, and the middle plug 12 are disassembled. In addition, since these can be cleaned in the disassembled state, the lid main body 10, the lid body 11, and the middle plug 12 can be kept clean.

As described above, the cover unit 3 of the present embodiment can simplify the structure and improve the cleaning performance. Therefore, the lidded container 1 of the present embodiment can be further improved in convenience of use by including such a lid unit 3.

The present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the present invention.

For example, although the above-described embodiment illustrates the container with a lid 1 applied to the above-described tabletop pot, the present invention can be widely applied to a container with a lid including a lid unit detachably attached to a container body having an upper opening.

In the above embodiment, the container with lid 1 having the heat retention and cold retention functions due to the container body 2 having the vacuum heat insulation structure is exemplified, but the present invention can be applied to a container with lid having a container body without a vacuum heat insulation structure.
