Technical Field
The present invention relates to a pants-type disposable diaper having a disposal tape.
Background
For the purpose of easily and hygienically disposing a pants-type disposable diaper, a technique is known in which a disposal tape is arranged in a three-folded state on a back side portion of the diaper. However, the length of the disposal tape simply made by three-folding the tape is only 3 times or about 3 times, even if the disposal tape is unfolded, and therefore the length of the disposal tape may be insufficient depending on the place where the disposal tape is fixed. In order to solve such a problem, patent document 1 proposes to use a disposal tape, at least a portion of which is extensible in the longitudinal direction, as a disposal tape to be disposed on the back side portion of a pants-type disposable diaper.
Disclosure of Invention
The invention provides a pants-type disposable diaper having a waist opening and a pair of leg openings, and having a stomach-side portion disposed on the stomach-side of a wearer and a back-side portion disposed on the back-side in a worn state.
A disposal tape for maintaining a disposal form of the disposable diaper is provided on an outer surface of the disposable diaper.
In the disposal tape, a fixing portion, an extension portion, and a fastening portion fixed to an outer surface of the disposable diaper are arranged in this order in the longitudinal direction of the disposal tape, and the disposal tape is in a three-folded state in which the fixing portion, the extension portion, and the fastening portion are laminated in this order.
The fastening portion and the extension portion of the disposal tape in the three-folded state are detachably joined to each other, and the extension portion and the fixing portion are also detachably joined to each other.
The tensile strength at which the fixed joint portion starts to elongate is higher than the tensile strength at which the extended portion starts to elongate.
The peel strength between the extension and the anchoring portion is lower than the tensile strength at which the extension begins to elongate.
The peel strength between the fastening portion and the elongated portion is lower than the tensile strength at which the elongated portion starts to elongate.
The tensile strength at which the elongation starts to be 6.5N or less.
The peel strength between the rigid connection portion and the extension portion is 4.0N or less.

Detailed Description
According to the technique described in patent document 1, when the used rolled diaper is discarded, the length of the disposal tape increases due to the elongation thereof, and therefore the rolled diaper can be easily maintained by the disposal tape. In this case, in order to reliably maintain the rolled-up state of the diaper, it is required to stretch the disposal tape as much as possible. However, if the waste tape is excessively elongated, the elongation portion exceeding the ultimate elongation at break may be broken.
The present invention relates to an improvement of a diaper having a disposal tape, and more particularly, to a pants-type disposable diaper in which the extensibility of the disposal tape is improved.
The present invention will be described below based on preferred embodiments with reference to the accompanying drawings. Fig. 1 shows an embodiment of a pants-type disposable diaper according to the present invention. A pants-type disposable diaper 1 (hereinafter, simply referred to as "diaper 1") shown in the figure is a type of wearing article used while being worn on the lower abdomen of a wearer, and has a waist opening 1W and a pair of leg openings 1L, 1L for this purpose. The diaper 1 is roughly divided into a stomach-side portion a positioned on the stomach side of the wearer, a back-side portion B positioned on the back side of the wearer, and a crotch portion C positioned in the crotch portion in a worn state.
The diaper 1 has a longitudinal direction X and a width direction Y orthogonal thereto. The longitudinal direction X coincides with the direction in which the diaper 1 is put on and taken off. The diaper 1 has a front sheet (not shown) on the side facing the skin of the wearer in the worn state, and a back sheet (not shown) on the side away from the skin of the wearer. An absorbent body 2 is disposed between the front sheet and the back sheet. The front sheet, the back sheet, and the absorbent body 2 are arranged at least over the entire crotch portion C, and extend from the crotch portion C along the longitudinal direction X to at least a part of the front side portion a and the back side portion B.
As the front sheet, the back sheet, and the absorbent body 2, the same materials as those used in the art so far can be used without particular limitation. In addition to these components, the diaper 1 may have other components that have been used in the art. For example, the diaper 1 may have leakage preventing cuffs (not shown) extending in the longitudinal direction of the absorbent body 2 on both side portions of the absorbent body 2.

In the diaper 1 of the present embodiment, 1 or more elastic members extending in the width direction Y can be arranged. For example, an elastic member extending in the width direction Y may be disposed in an extended state in the vicinity of the waist opening 1W or in a waist portion, which is a portion between the waist opening 1W and the leg openings 1L. By disposing the elastic member, the diaper 1 can be further fitted to the body of the wearer, the wearing feeling of the diaper 1 can be improved, and leakage of excrement can be effectively prevented. However, since the elastic member is disposed, there are cases where irregularities due to the elastic member are formed on the outer surface of the diaper 1 at the location where the elastic member is disposed. When the
In the present embodiment, the diaper 1 can be formed with a waist gather 3 and a leg gather 4 in the peripheral edge region of the diaper 1. Here, the peripheral region refers to a region on the waist end side of the absorbent body 2. These wrinkles are often formed in a low-rigidity region from the viewpoint of improving the stretchability. Here, the low stiffness region refers to a region having a lower stiffness than a region having a higher stiffness obtained by overlapping the absorbent body 2 described below. When the
Fig. 3 shows how the diaper 1 according to the present embodiment is discarded. As shown in the drawing, when the diaper 1 is discarded, the diaper 1 is rolled up from the crotch portion C toward the waist opening 1W so that the abdomen-side portion a of the diaper 1 faces inward, thereby forming a rolled-up state. In the finished state of the rolled-up form, the
