Description

  The present invention relates to a disposable pant, and more particularly, to a disposable pant that is difficult to peel off during wearing, and that can be independently adjusted to the waist opening size.

  Conventionally, disposable pants such as a pants-type diaper having a waist opening and a pair of leg openings usually seal both sides of the front and back of the pants, and the waist opening and a pair of leg openings Therefore, flanges (protruding edges) formed by joining at least the outer layer portions to the left and right sides are formed on both side portions of the pants.

However, in such disposable pants, if there is a protruding flange portion, it may be caught during use, and the joint outer layer portion may peel off from that portion as a base point. In addition, babies and adult wearers with dementia sometimes pinched the protrusions and removed them. Therefore, it is conceivable to join the outer layer part firmly so that the user can not peel it off, but the outer layer part becomes very hard and the skin is damaged during use, or the outer part is bonded when discarded. There was a problem that it was impossible to tear.
Further, when the flanges are on both sides, the appearance is not good and there is no underwear. In particular, in the case of adult diapers, the presence of the flange portion causes a psychological burden on the wearer.

  On the other hand, Patent Document 1 describes a flangeless seam in which both ends of an article such as a pants-type diaper are formed in a loop shape and are separably bonded using a barrier member. The joint portion using the flangeless seam has no protrusion and looks good, but requires a complicated processing step such as a process of bending the end portion into a loop shape. In addition, since a part of the barrier member may come into contact with the wearer's skin, there is a possibility that the wearer may feel uncomfortable even if a material that is kind to the skin is used.

Moreover, in patent document 2, a fastening part is provided on the surface of a surface sheet in a stomach side part and a back side part, and the waist part adjustment member which adjusts the length of a waist part only in the both-sides edge part of a back side part. The disposable diaper provided with is described, and a mechanical hook tape or the like is cited as a material for forming the fastening portion. Moreover, it is described that a waist part adjustment member consists of the release part by which the surface is peel-processed, and the fastening part by which the adhesive is apply | coated to the surface connected with this release part. When using this diaper, the fastening part is fastened to the landing tape provided on the abdomen side of the diaper and the size of the waist part can be easily adjusted even after being worn on the wearer. It can be done.
However, the disposable diaper described in Patent Document 2 is an unfolded diaper and cannot be used as pants after breaking the fastening portion. In recent years, it has been required to adjust not only the waist part but also the opening size of the leg part. In addition, it has been required to adjust the sizes of the waist and leg portions by means provided by simpler processing.

  Therefore, the present invention is a disposable pant that can be manufactured without requiring a complicated process, is difficult to peel off during movement, and can be easily adjusted in size after being worn. The purpose is to provide. It is another object of the present invention to provide a disposable pant that solves the above-mentioned appearance problems and can be easily discarded after use.

  The present invention relates to a disposable pants having a waist opening and a pair of leg openings, and both sides of the disposable pants are connected to be tearable, and the waist openings and leg openings in the both sides of the pants The object is achieved by a disposable pant characterized in that a fastening means is provided on the outer surface of the pant so as to be detachable from the other outer surface of the pant and capable of adjusting a waist opening size or a leg opening size.

The disposable pants according to the present invention can fold and fasten the rim-like joint portion including the joint portion, so that the ridge portion does not remain, the wearer cannot grasp the joint portion, and the joint portion is peeled off or torn. Prevents stable use. In addition, caregivers can freely adjust the opening size by simply folding back the side part according to the wearer's waist size and underfoot size and their changes. The fit of the part can be further improved.
In addition, the appearance of underwear can be maintained by not letting the presence of the protruding edge portion, and in this respect, it is particularly suitable as a pants diaper for adults.

  Furthermore, when the disposable pants of the present invention are used as a disposable diaper, as an alternative to the conventional disposal tape, it is possible to use a fastening means that is detachable from other outer surfaces. The diaper is rolled up in the longitudinal direction, fixed by fastening means and discarded. Therefore, the diaper is easy to dispose of, and the excrement can be confined in the rolled pants and covered with the back sheet, so that it can be treated hygienically.

  Moreover, it becomes possible to reduce the sealing strength of a side junction part, and it can be easily broken at the time of disposal. Moreover, since a junction part does not contact skin, it becomes a kind to skin.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
The disposable pants as an embodiment of the present invention is a pants-type diaper as shown in FIG. FIG. 1 is a perspective view schematically showing the structure of the back side of the pant-type diaper 1 when the pant-type diaper 1 is attached.

  As shown in the figure, the main body of the pants-type diaper 1 is fixed on the top sheet 2 applied to the body surface of the wearer (not shown), the back sheet 3 serving as the outer surface when worn, and the inner surface of the back sheet 3. And the absorbent body 4 covered with the top sheet 2. At least the region of the abdominal side portion 5 including the back sheet 3 and the region of the back side portion 6 are joined to each other at the right and left side edges in the width direction by heat fusion or the like, and the protruding side joint portions 8 are arranged on both sides of the diaper main body Accordingly, the diaper main body is formed into a pants shape having a waist opening 9 through which the wearer's torso is passed and a pair of left and right leg openings 10 through which the lower leg of the wearer is passed. ing. In FIG. 1, the size of the range surrounded by the waist opening 9 is the waist opening size, and the size of the range surrounded by the leg opening 10 is the leg opening size.

  Further, fastening means 11 detachably attached to the other outer surface of the pant-type diaper 1 is provided on the outer surfaces in the vicinity of the waist opening 9 and the leg opening 10 in the both sides on the part 6 side of the pant-type diaper 1. There are four places.

  FIG. 2 is a plan view illustrating the outer shape of the pant-type diaper 1 shown in FIG. 1 with the outer side (exterior side) facing upward and in the unfolded and extended state, and the symbols mean the same as those shown in FIG. In FIG. 2, the absorbent body 4, the waist elastic member 13, and the leg elastic member 14 that are not exposed on the surface are indicated by broken lines for explanation.

  The top sheet 2 is a liquid-permeable sheet that allows the excrement to permeate the absorbent body 4, and preferably has a touch close to underwear. Examples of such a liquid-permeable sheet include a woven fabric, Nonwoven fabrics, porous films and the like are preferred. In addition, a hydrophobic compound such as a silicone-based oil or paraffin wax is applied to the periphery of the top sheet 2 and subjected to water repellent treatment.

The back sheet 3 is a liquid-impermeable sheet, and is made of, for example, a composite material of a film and a non-woven fabric. A moisture-permeable back sheet, an inner layer non-woven fabric, and an outer layer non-woven fabric are sequentially formed from the side to which the absorber 4 is fixed. It can form by joining by a conventional method.
This moisture-permeable back sheet is also called a leak-proof sheet and has liquid impermeability, and is disposed outside the absorbent body 4 to prevent leakage of excrement, for example, thermoplastic. A liquid-impermeable sheet with moisture permeability that allows the vapor that has been stretched by adding a filler to the resin to pass through is preferably used.
Moreover, as an inner layer nonwoven fabric and an outer layer nonwoven fabric, a liquid-impermeable or water-repellent nonwoven fabric is used.

The absorbent body 4 absorbs and retains excretion that has permeated through the surface sheet 2, and is preferably, for example, a combination of a high-molecular water-absorbing polymer mainly composed of defibrated pulp, and a thermoplastic resin, cellulose. What heat-processed to the mixture of a fiber and a high polymer water absorption polymer is preferable. The polymer water-absorbing polymer may be present in any one of the upper layer, the middle layer, and the lower layer of the absorber 4, for example, starch-acrylic acid (salt) graft copolymer, starch-acrylonitrile copolymer saponified product, Preferred examples include sodium carboxymethylcellulose cross-linked products and acrylic acid (salt) polymers.
The side surfaces and the upper surface of the absorbent body 4 are covered with one or a plurality of types such as paper, nonwoven fabric, and apertured film, for example, as necessary.
The absorber 4 is interposed between the top sheet 2 and the back sheet 3 while being fixed to the back sheet 3.

  The side joint 8 is preferably configured to be easily torn in the vertical direction, whereby the disposable diaper can be easily torn at the joint without contaminating the wearer's skin. The diaper can be easily removed and discarded. The joining portion 8 is preferably formed by joining the front body 5 and the rear body 6 on the left and right, for example, using a heat seal or a hot-melt adhesive.

  In the pants-type diaper 1, a plurality of waist elastic members 13 are arranged around the waist opening 9 in an annular shape around the entire circumference of the waist opening 9 in order to improve fit to the wearer's waist. Forming a waist gather. A plurality of leg elastic members 14 are annularly or substantially annularly arranged around the leg opening 10 to improve the fit from the wearer's collar to the thigh, thereby forming a leg gather. ing. These elastic members 13 and 14 are both arranged between the inner layer nonwoven fabric and the outer layer nonwoven fabric described above. Preferred examples of the elastic member include thread rubber, flat rubber, film type rubber, and film-like foamed polyurethane.

  Further, in the ventral side portion 5 and the back side portion 6 of the diaper main body, a pair of waist flaps extending outward from the longitudinal end edges of the absorbent body 4 and both lateral edges of the absorbent body 4 A pair of left and right side flaps of the abdomen and the dorsal side extending outward in the width direction are disposed. A side elastic member 15 is disposed on each flap. For this reason, the waist flap and the side flap have elasticity. The side elastic member is preferably made of thread rubber and is disposed between the inner layer nonwoven fabric and the outer layer nonwoven fabric.

  When the pant-type diaper 1 is attached, the side joint 8 is folded back to fold the main body of the pant 1, and a back sheet that can be fastened to the fastening means 11 or a fastening member separately mounted thereon, and fastening means 11 is releasably bonded. By this, since the junction part 11 does not contact skin, it becomes a kind to skin. Moreover, since a force is not directly applied to the side joint portion 8 when the diaper is worn, even if the side joint portion 8 itself is weakly joined, the side joint portion 8 is not easily broken when worn. For this reason, it becomes possible to reduce the sealing strength of the side joint part 11, and it can be easily broken at the time of disposal. Moreover, it is preferable that the adhesive force (seal strength) of the said side junction part 8 of this invention is 5-15N / 30mm, and 8-12N / 30mm is further more preferable. These adhesive strengths are lower than 15 N / 30 mm of the sealing strength of the side part of the conventional disposable pants.

  Here, the seal strength of the side joint portion 8 can be measured by the following measuring method. Centered at a point 25 mm from the waist opening of both side joints, a point 25 mm from the leg opening, and an intermediate point between the waist opening and the leg opening 30 mm vertically (width direction) and 50 mm wide (width direction) Cut out the sample. Using a tensile tester with 50 mm between chucks, the seal portion of the sample is peeled off, and the maximum tensile load of the sample is measured. The measurement is performed on the above three samples, and the average value is taken as the seal strength.

The folding part having the fastening means 11 is present at four places in total, two places on each side (waist part and leg part). Thereby, both the waist opening size and the leg opening size can be adjusted independently, and for example, the size can be adjusted so that the leg portion fits snugly while the ventral side of the waist portion is loosened.
The fastening means 11 may be on the abdomen side or on the back side as viewed from the side joint portion 8, but if it is on the back side, for example, it is difficult to remove it when the wearer is a person with dementia. preferable.

In the width direction of the diaper 1, a test piece including all the fastening means 11 and having a grip allowance portion 32 having a length of 10 mm is cut out from the diaper main body portion. That is, a test piece for measuring fixed strength of 30 mm width in the longitudinal direction of the diaper 1 and 40 mm length in the width direction of the diaper 1 is collected. FIG. 8B is an enlarged sectional view showing the test piece. Next, the back sheet 3 of the body fixed part having the same dimensions as the above-mentioned test piece (30 mm width in the vertical direction × 40 mm length in the width direction) is cut out, and the cut out back sheet 3 is a cross-sectional view of FIG. As shown in FIG. The back sheet 3 is a non-woven fabric that can be engaged with the male material of the mechanical fastener on the outer surface that does not include the absorber, that is, the outer surface non-woven fabric obtained by removing the absorber from the product. However, it was cut out from the entire surface. However, when it is difficult to cut out the back sheet 3 described above, a piece cut out from a portion where the absorber is present (that portion excluding the absorber) may be used. Next, as shown in the cross-sectional view of FIG. 8D, the test piece on which the back sheet 3 is overlapped is pressed from the back sheet 3 side by the pressurizing unit 34 at 40 g / cm ² for 1 minute, and the fastening unit. 11 and the back sheet 3 are fixed. Then, as shown in the cross-sectional view of FIG. 8 (e), the peeling force between the fastening means 11 and the back sheet 3 fixed at a peeling speed of 300 mm / min by the tensile tester 35 is measured, and the maximum load is fixed strength ( N / 30 mm).

  Moreover, it is preferable that at least a part of the fastening means 11 is provided on the outer surface of the back sheet 3 at a position where the elastic member 13 is disposed. With this arrangement, as shown in FIG. 4 to be described later, when the fastening means 11 and the back sheet 3 (the support body 19 mounted on the back sheet 3a in FIG. 4) are fixed, the fixed part. Due to the action of the elastic member 13, a shearing direction force is applied, the fixing strength between the fastening means 11 and the back sheet 3 is increased, it can be firmly fixed, it is difficult to peel off during movement during mounting, and a stable fixed state is achieved. Obtainable.

  FIG. 3 is a schematic cross-sectional view showing an embodiment of the joint 8 provided with the fastening means 11. The joining portion is composed of a joining region 17 where two backsheets 3a and 3b are heat-sealed, and the back sheet tip portions 3c and 3d protruding therefrom. Before the fusion, the back sheets 3a and 3c form a continuous series of sheets. The back sheets 3b and 3d also form a series of sheets before fusing. Moreover, the arrow 18 in FIG. 3 shows the width | variety of the junction part which forms a protrusion. In the illustrated example, the bonding portion is formed only by the back sheet 3 for the sake of simplicity. However, the bonding portion may be formed by including the top sheet 2 or each elastic member. .

  The fastening means 11 is not particularly limited as long as it is a means that is detachable from the other outer surface of the pants, and examples thereof include a male material of a mechanical fastener, an adhesive tape with release paper, a button, a hook, and the like. It is preferable that it is a male material of a mechanical fastener.

  Here, the mechanical fastener is composed of a male material in which a large number of protruding male engaging portions are disposed on the surface, and a female material in which loop portions, net-like portions, and the like are disposed on the surface. It is a fastening device that is made to join the female member and the female member in an interview.

  As the female material of the mechanical fastener, for example, a material formed by fixing a synthetic fiber or the like so as to form a number of loop portions on a base sheet (resin, paper, nonwoven fabric sheet, or the like) can be used. However, the outer layer nonwoven fabric of the back sheet can be used as a female material as it is.

  As a nonwoven fabric when using a nonwoven fabric as a female material, an air-through nonwoven fabric, a spunbond nonwoven fabric, a heat roll nonwoven fabric, a chemical bond nonwoven fabric, and the like can be used. It is preferable to use it. Moreover, as a fiber which comprises a nonwoven fabric, a short fiber staple fiber, a long fiber filament, etc. can be used. Moreover, a core-sheath type or a side-by-side type composite fiber can also be used. Various thermoplastic resins can be used as the constituent material of the fiber.

In particular, as the main constituent fiber of the nonwoven fabric, a core-sheath type composite fiber is preferably used, and in particular, a core-sheath type composite fiber made of the same series of resin components is preferably used. In this specification, the resin components of the same series are similar to each other in the chemical structure of the resin component constituting each of the sheath component and the core component (that is, the main chemical structure is the same), and are compatible with each other. By seed resin or resin mixture. In this case, it is desirable that the interfacial strength between the core component and the sheath component is greater than the joint strength. When the nonwoven fabric is composed of two or more kinds of fibers, it is preferable that the main constituent fiber is a core-sheath type composite fiber made of the same series of resin components, and the ratio of the composite fiber is particularly high. It is preferably 50% by weight or more.
As a specific combination of the core component and the sheath component, polypropylene (PP) is used as the core component, a low melting point PP is used as the sheath component, polyethylene terephthalate (PET) is used as the core component, and a low melting point is used as the sheath component. Examples include combinations using PET.

In addition, the fastening means 11 used in the present invention is provided with a support body 19 made of a loop material as another female material at a site where the mechanical fastener is brought into contact as shown in the sectional view of FIG.

Thus, it is possible to fit the wearer, and it is possible to accurately prevent leakage of excrement and the like.

  In addition, for a long-time bedridden person, the size of the waistline does not change so much, but the size of the undercarriage tends to be gradually reduced. In some patients with certain diseases, the size of the undercarriage does not change much, but the size of the girth may gradually increase. In such a case, in the past, there was a limit to using a pants-type diaper of the same size in order to fit both the leg and the waist well. However, the pant-type diaper 1 of the present invention is not worn by the wearer. The size of the opening can be adjusted according to the change in size, so that the diaper of one product size fits the wearer's torso and legs well over a long period of time by simply fixing the fastening means to the exterior. Can be used in

  Since the pants-type diaper 1 is configured as described above, after use, the fastening means 11 is peeled off from the other outer surface portion of the fixed diaper, and then the side joint portion 8 is peeled off. The diaper can be easily and hygienically discarded by removing it from the wearer and making the diaper rolled up and fixing the joining member 11 and the outer surface of the diaper 1 again.

  The underpants type diaper 1 having such a technical effect can employ, for example, the same configuration as a conventional underpants type diaper except that the above-described fastening member 11 is provided. Therefore, it is possible to manufacture mechanically in a series of manufacturing steps only by making a desired change to existing manufacturing equipment.

  Thus, in the production of the pant-type diaper 1, it is almost unnecessary to use new raw materials, and it is only necessary to add the above-mentioned fastening means 11 to the existing manufacturing equipment, so that the raw material costs increase. It is easy to reduce capital investment.

  As mentioned above, although embodiment which concerns on the underpants type diaper of this invention was described, in this invention, it is possible to give various change, improvement, a combination, etc. to the underpants type diaper 1 illustrated by these embodiment. Also, without using an absorber, for example, paper pants for travel, paper shorts used in beauty salons, etc., on the outer surface near the waist opening and the leg opening near the both sides, By providing a means that is detachable from the other outer surface of the pants, similarly, the joint portion is prevented from being peeled off or torn, and the side portions are folded back so that the wearer's waist size and underfoot size Accordingly, the size can be easily adjusted freely, and the fit of the waist part and the leg part can be further improved.
