Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a disposable pant for children or adults, and more particularly, to an inexpensive disposable pant that can urinate or replace an auxiliary absorber without raising or lowering the pant.
[0002]
[Prior art]
The disposable pants are mainly composed of a back sheet, an absorber, and a top sheet. As the back sheet, a laminated sheet including at least one liquid-impervious leak-proof sheet is generally used, and as the top sheet, a nonwoven fabric, a perforated plastic sheet, or the like is used. Absorbers are commonly used in which pulp fibers, highly water-absorbent resins, thermoplastic synthetic resins, and the like are mixed and heat treated to improve shape retention. In addition, around the waist opening and the pair of leg openings of the disposable pants, stretched elastic members (for example, a plurality of elastic yarns, elastic tapes, etc.) are attached to the wearer's waist circumference and leg circumference. It is configured to adhere closely to and prevent leakage.
[0003]
Such disposable pants are often used for children who have started walking, for training the transition to toilet use, and for capturing urine during incontinence for adults.
[0004]
However, disposable pants with an absorbent body are bulky because the pants are generally thick and bulky, especially when worn by adults, wearing ordinary clothing over the pants can be very clunky There is a problem. In addition, in order to change disposable pants for each urination (incontinence), many pants must be carried when going out, and the amount of baggage increases, and the disposable pants are relatively expensive. There was an important problem for actual users to put a heavy burden.
[0005]
For this reason, a method is adopted in which a small auxiliary absorber is used together with the disposable pants, and only the auxiliary absorber is replaced after urination if the disposable pants are not dirty. However, even if a small auxiliary absorber is used in combination, it is worn in bulky disposable pants, so that the appearance is not improved. In addition, even disposable pants that can be used for a relatively long period of time, it is necessary to raise and lower the pants every time a small auxiliary absorber is replaced. There was a problem that the joint part of was broken. Also, many incontinence people have a sense of urine and go to the bathroom, and it takes time to perform the actual urination action, so the underwear is dirty. There are currently no disposable pants that are considered and satisfied by the user.
[0006]
[Problems to be solved by the invention]
Therefore, in the present invention, it is a disposable pant that is not bulky so that it does not affect the appearance even if it is worn only with pants or in combination with an auxiliary absorber, and the auxiliary absorber is replaced or urinated. It is an object of the present invention to provide disposable pants that can be easily performed.
[0007]
[Means for Solving the Problems]
The present invention relates to a disposable pants having a waist opening and a pair of leg openings, and an elastic member is provided around these openings. The disposable pants have an opening in the center of the front of the pants. The center opening is provided with a sheet-like lid member that can open and close the center opening, and the center opening is a point that extends from the front of the pants through the crotch to the back side. Have. At least a part of the peripheral edge of the central opening is provided with a joined part or a joined part, and the lid member is provided with a joined part or joined part that can be attached or detached in correspondence with the joined part or the joined part. It is a preferred embodiment of the present invention to adopt a configuration in which the joining portion is an engaging member of a mechanical surface fastener and the joined portion is a locking member.
[0008]
In addition, even if the lid member is formed of a sheet material separate from the disposable pants, a part of the lid member is connected to the pants, and the lid member is formed by a cut piece when forming the central opening. It may be what you did.

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the disposable pants of the present invention will be described with reference to FIG. As shown in FIG. 1, the disposable pants P of the present invention has an opening 6 formed in the center of the front portion, and a sheet-like lid member 7 that can be opened and closed is attached to the center opening 6. The disposable pants P are formed by folding a sheet material 1 in which a plurality of non-woven fabrics (or non-woven flexible perforated or non-perforated plastic sheets) are laminated back and forth, and intermittent or non-intermittent joining lines 2 on the left and right sides, 2 are joined together. A waist opening K1 is formed in the upper part of the pants P, and a pair of leg openings K2, K2 are formed in the lower part. Around the openings K1, K2, an elastic member (a plurality of elastic yarns) in an expanded state is formed. (Elastic tape or the like) 31, 41 are attached to form a waist gather and a leg gather. In order to improve the bulk of the disposable pants and make it cheaper, it is preferable to use the sheet material 1 having a structure in which the absorbent body is not laminated on the premise that the auxiliary absorbent body is used together. However, if the absorbent body is very thin, for example, having a thickness of 5 mm or less, the absorption and shape retention is improved by using a super-high water-absorbent resin and a small amount of pulp fiber and heat-fusible fiber. In this case, a laminate having an absorbing ability may be used for the sheet material 1 or the lid member because the thickness does not affect the appearance.
[0010]
The center opening 6 is provided only in the center of the front of the pants for easy understanding in FIG. 1, but it is preferably provided from the front (abdominal side) of the pants P to the back through the crotch. This is because the auxiliary absorber can be easily replaced, and urination can be easily performed by both men and women when urinating instead of incontinence.
[0011]
The lid member 7 is joined and fixed to the pants P by a joining line 72. The lid member 7 is formed of a nonwoven fabric, a plastic sheet, or a laminate thereof. The cut piece cut when forming the central opening 6 may be used as a part of the lid member. At this time, it is not necessary to provide the joining line 72, and the lid member and the sheet material 1 may be integrally attached without cutting one side of the central opening. Since only the cut piece is small as a lid member, the cut piece can be used as a lid member by attaching another sheet material around the cut piece or by stacking sheets having a larger area than the cut piece.
[0012]
The central opening 6 and the lid member 7 need to be detachable. In FIG. 1, the joined portion 61 on the pants body side and the joined portion 71 on the lid member side are attached to the central opening 6 and a part of the periphery of the lid member 7 (three places), and both are attached and detached. A free configuration is shown. As the joining member and the member to be joined, an engaging member and a locking member of a mechanical surface fastener are preferably used, and a combination of an adhesive tape and a releasable target tape, or a combination of a self-adhesive adhesive tape, Also good. When using a mechanical hook-and-loop fastener, if you select a mushroom-type hook as the locking member, it feels good and it can be engaged and locked even if the engaging part is a nonwoven fabric of the pants body. Since it is not necessary to provide a loop-shaped engaging member, it is preferable. In addition, a junction part and a to-be-joined part may be attached reversely, and also a junction part or a to-be-joined part may be provided in the perimeter of a center opening or a cover member.
[0013]
FIG. 2 shows an embodiment in which the joint fixing portion between the pants P and the lid member 7 is provided on the upper side of the opening 6. That is, the joining line 72 is on the upper side of the opening 6, and the pants-side joined parts 61 a, 61 b, 61 c are pants attached so that they can be joined to the joining parts 71 a, 71 b, 71 c on the lid member side, respectively. is there. Of course, the joining line 72 in FIG. 2 may be appropriately changed to the right part of the opening 6 (where the joining part 61a is present) or the left part (where the joining line 61b is present).
[0014]
FIG. 3 is a perspective explanatory view showing a manufacturing example of the disposable pants shown in FIG. The disposable pants P are continuously produced while moving in a state of being arranged in the horizontal direction. The belt-shaped nonwoven fabric 11 is moved in the right direction in the figure, and the elastic members 31 and 41 in an expanded state are attached while applying an adhesive to the nonwoven fabric. The leg elastic member 41 is joined while separately bending the front and rear pants. Then, another nonwoven fabric 13 having a shorter width than the nonwoven fabric 11 is laminated on the nonwoven fabric 11, both side portions in the width direction of the nonwoven fabric 11 are folded inward, and the elastic members 31 and 41 are sandwiched between the nonwoven fabrics 11 and 13. The sheet material 1 having the above structure is manufactured.
[0015]
Next, the notch K for the leg portion and the central portion opening 6 are formed in the sheet material 1 by the two cutter rolls 22 and 23. The leg cutouts K are drawn out into a circular shape or an oval shape, and the leg openings K1 and K2 of the two adjacent disposable pants P are formed by one cutout K. A central opening 6 is formed in a desired size and shape between adjacent notches K, K. The central opening 6 has a size from the abdominal side to the part of the back side through the crotch and is preferably substantially trapezoidal, but may be oval, rectangular or semicircular, It can be selected as appropriate.
[0016]
The sheet material 1 provided with the joined portion 61 after the notch is superposed on the place where the lid members 7, 7. The lid member and the sheet material are joined together by a joining line 72 by a known means such as an agent or heat seal. Further, when the sheet material is folded in two in the width direction, joining lines 2 and 2 are formed at portions corresponding to the left and right side portions of the disposable pants, and the gap between the joining lines 2 and 2 is cut, individual disposable pants Is completed (FIG. 4).
[0017]
【The invention's effect】
The present invention is configured as described above, and can provide a disposable pant that is not bulky and does not resonate even when worn only with pants or when used in combination with an auxiliary absorber. The pants of the present invention can easily replace the auxiliary absorbent body due to the presence of the central opening and the detachable lid member. Further, when urinating consciously, the trouble of raising and lowering the pants can be saved, so that the inconvenience of incontinence before urination is eliminated.
