Description

  The present invention relates to a pants-type diaper for playing with water, and more particularly, to a pants-type diaper for playing with water suitable for a swimsuit worn by a child such as an infant or the like in swimming or swimming or underpants worn under a swimsuit.

  A normal disposable diaper, for example, a pants-type diaper is a pants-type absorbent main body formed by at least a liquid-permeable top sheet, a liquid-impermeable sheet, and an absorbent body interposed between these sheets. A three-dimensional gather for preventing liquid leakage is provided on the upper surface, that is, the upper surface of the top sheet, and this absorbent main body is bonded to an outer layer sheet called a back sheet formed of a nonwoven fabric or the like to form a pants-type diaper. The absorbent body absorbs excretions such as urine and feces excreted on the upper surface of the top sheet, and as a main component, a pulp material such as flap-like wood pulp and cotton-like pulp, and a polymer absorbent (Super Absorbent Polymer: hereinafter referred to as “SAP”) (for example, see Patent Document 1).

On the other hand, conventionally, children's swimming pants are commercially available and used for children's water play and swimming.
Japanese Utility Model Publication No. 10-314217

  However, when the disposable disposable diaper is worn, the thickness of the absorbent body makes the crotch part bulky and restricts the movement of the leg part. When playing in the water or swimming in a public pool such as an infant classroom, the SAP contained in the absorber absorbs water and the weight of the paper diaper itself increases, resulting in a further loss of freedom. . In addition, simply attaching and fixing the diaper with the elastic stretchable member disposed in the waistline portion, the diaper having increased weight in water as described above is further added with water resistance, so that it easily falls off. There was a problem. Furthermore, SAP or pulp material may flow out of the leg diaper of the paper diaper or an opening such as the waist part of the diaper and contaminate the water, and the function of preventing excrement leakage is also used in the above-mentioned diapers. There is a problem from the viewpoint of hygiene because there is a possibility that the excrement may be lost due to the slipping off, and there is a problem that it is not suitable for playing with water.

  On the other hand, in conventional swim mink pants, excrement such as urine and feces may be leaked in water in the case of infants and the like, and this leaks out from the opening of the pants and further contaminates the pool water. Therefore, it was not preferable in terms of hygiene.

  In addition, although the thing which does not use the said SAP as a paper diaper is also well-known, since this paper diaper is for a wearer's training to the last, and is not what is always worn, and is not for water play, as above It cannot solve each problem.

  In view of the above-mentioned conventional problems, the present invention can prevent the excrement of the wearer and the SAP contained in the absorber from flowing out of the opening of the pants and the like, and the wearer can move freely. Another object of the present invention is to provide a disposable pants-type diaper for playing with water that can be surely prevented from falling off a diaper in water.

The pants-type diaper for water play of the present invention forms an absorbent main body at least by a liquid-permeable top sheet, a liquid-impervious sheet, and an absorbent body mainly composed of a pulp material interposed between these sheets. A back sheet made of a liquid-permeable nonwoven fabric is disposed on the back surface of the absorbent main body opposite to the absorbent body of the liquid-impervious sheet, and the back sheet is disposed on the left and right legs around the absorbent sheet. Side flaps are formed by extending to the side of the main body, and a waste collection pocket is formed on the top sheet by a three-dimensional gather that stands up from the top sheet on both sides of the absorbent main body, and the waist portion of the back sheet In addition, an elastic elastic member is disposed on the side part between the waist part and the leg part, and the elastic member is not disposed on the side flap part. The amount of the following a shift folded into shaped cross section rather to rise, and disposed the elastic stretchable member in the folded portion on both sides in the width direction, polymeric absorbent contained in the absorber (SAP) Is 10% by weight or less, and the amount of the pulp material does not exceed 10 g.

According to this configuration, even when the wearer excretes in water, the excrement is accommodated and retained in the excrement accommodation pocket and does not flow out of the opening of the pants or the like, and constitutes an absorbent main body. Since the absorbent body is also mainly composed of pulp material, the polymer absorbent or the like does not flow out of the opening or the like, so that it is possible to prevent the water in the pool and the like from being contaminated. Since it is not bulky and does not swell even when it gets wet, the wearer can freely move around, and elastic elastic members are placed not only on the waistline part of the backsheet but also on the side part between the waistline part and the leg part. Since it is installed, it is possible to reliably prevent the diaper from slipping underwater, to ensure free movement, and to exert a great effect in preventing leakage of the polymer absorbent and excrement. In addition, even if the diaper is slightly displaced, a solid gather having an elastic elastic member disposed including both ends of the solid gather on both sides of the folded portion in the width direction rises, and the inside of the waste storage pocket is external Therefore, the above effect can be obtained with certainty. In particular, the SAP contained in the absorber may be an amount of 10% by weight or less of the entire absorber, and even if it enters water such as a pool, the SAP can suppress the outflow to almost zero as in the prior art.

  Further, it is preferable that the elastic elastic member of the side portion is disposed so that the tightening force per 1 cm width when worn is 140 gf / cm or more, so that the effect of preventing slippage in water can be reliably obtained.

Moreover, the said effect is achieved more because the volume of the excrement accommodation pocket is 600-800 cm < ³ >, and a sufficiently large volume is ensured.

  In addition, if the liquid-impervious sheet is disposed more than the area of the absorbent body and less than 70% of the diaper flat area, the liquid-impervious sheet may be damaged by water strongly hitting the absorbent body from the outside. It is suitable for preventing the diaper and performing the protective function of the absorbent body and ensuring the air permeability of the entire diaper.

In addition, if a back sheet made of a liquid-permeable nonwoven fabric is disposed on the back of the absorbent main body opposite to the absorbent body of the liquid-impermeable sheet, the diaper can have an affinity for water in water. A suitable wearing feeling can be obtained. In particular, it is preferable that the water pressure resistance of the nonwoven fabric of the backsheet is 100 mmH ₂ O or more because water does not excessively penetrate into the diaper while having liquid permeability.

According to the present invention, excrement is accommodated and retained in the excrement accommodation pocket and does not flow out from the opening of the pants or the like, and the absorbent body constituting the absorbent main body is also mainly composed of pulp material. In addition, since the polymer absorbent does not flow out from the opening or the like, the water in the pool can be prevented from being contaminated, and the absorbent body is not bulky and does not swell very much even when wet. So the wearer can move around freely, and elastic elastic members are arranged not only in the waistline part of the back sheet but also in the side part between the waistline part and the leg circumference part, so the diaper shifts in water Falling can be reliably prevented. In addition, even if the diaper is slightly displaced, a solid gather having an elastic elastic member disposed including both ends of the solid gather on both sides of the folded portion in the width direction rises, and the inside of the waste storage pocket is external Therefore, the above effect can be obtained with certainty. In particular, the absorption capacity of urine and the like can be maintained by setting the content of the polymer absorbent (SAP) to 10% by weight or less in the absorber, and even if it enters water such as a pool by not using SAP, Since SAP does not flow out as in the past and the amount of pulp material used is a small amount not exceeding about 10 g, which is about half of the conventional amount, it is possible to more reliably prevent the pulp material from flowing out, and the absorber It is not bulky, and the thickness of the product itself is reduced. Therefore, there is no bulkiness when worn, and the legs can be moved freely.

  Hereinafter, an embodiment of a pants-type diaper for playing with water according to the present invention will be described in detail with reference to FIGS.

  1 to 4, 1 is a pants-type diaper for playing with water (hereinafter simply referred to as a diaper), which is mainly a liquid-permeable top sheet 2, a liquid-impermeable sheet 7 made of a waterproof film, and the like, and these sheets. An absorbent main body 5 is formed by the absorbent body 4 interposed therebetween. As shown in FIG. 4, the absorber 4 is covered with an upper crepe paper 6u and a lower crepe paper 6d, and is configured to contain a pulp material therein.

Under the liquid-impervious sheet 7 of the absorbent main body 5, a back sheet 3 made of a two-layered nonwoven fabric or the like is disposed. The nonwoven fabric of the back sheet 3 is preferably one that is liquid permeable and has a water pressure resistance of 100 mmH ₂ O or more. Further, the use area of the liquid-impervious sheet 7 is preferably set to a minimum flat area under a condition larger than the flat area of the absorbent body 4, for example, 70% or less of the entire flat area of the back sheet 3. It is.

  As shown in FIG. 3, the absorbent main body 5 has a planar shape formed in an hourglass shape together with the absorber 4. Further, a plurality of elastic elastic members 10 made of rubber strings or the like are disposed on the back side waistline portion 9b and the abdomen side waistline portion 9f of the substantially identical backsheet 3 that is slightly larger than the end flap portion. EF is formed. The side end portions of the waist portion 9b on the back side and the waist portion 9f on the abdomen side are integrally joined with an adhesive or the like to form the waist portion 9. In the left and right leg surrounding portions 11, the back sheet 3 is extended to the side to form a side flap portion SF. In the side part 12 between the waist part 9 and the leg part 11, an elastic elastic member 10 made of a plurality of thread rubbers or the like is disposed, so that the tightening force acts not only on the waist part 9 but also on the side part 12. It is configured. The tightening force of the side portion 12 by the elastic elastic member 10 is preferably set to 140 gf / cm or more per 1 cm width. In addition, as the elastic elastic member 10 of the side part 12, not only a rubber thread but an elastic film can also be used. Thus, finally, a pants-type diaper 1 that is the same as a conventional disposable diaper in appearance as shown in FIG. 1 is completed.

  As shown in FIGS. 2 and 3, three-dimensional gathers 8 are provided on both sides of the upper surface of the top sheet 2 to prevent leakage of excrement such as urine and feces along the longitudinal direction between both end flaps EF and EF. Is provided. As shown in FIG. 4, the three-dimensional gather 8 has an absorbent main body 5 whose one side portion is folded back in a cross-sectional shape so as to smoothly follow up the displacement of the diaper 1 when worn. A plurality of elastic elastic members 10 are disposed at appropriate intervals in the width direction. The absorbent body 4 is provided in the longitudinal direction along both side edges in the width direction. The three-dimensional gather 8 provided in this way forms a waste storage pocket 13 for storing waste such as urine and feces in the center of the absorbent main body 5.

  The above members are bonded to each other by an adhesive such as a hot-melt adhesive as shown by a cross in FIG. 4. However, since these are generally well-known techniques in the technical field, The detailed description of is omitted.

In the diaper 1 of this embodiment, by such a larger standing設高of standing gathers 8, or extend the upright range, the volume of the excrement receiving pocket 12 to 600 to 800 ^3, set preferably around 700 cm ³ Has been. This volume is several times that of conventional disposable diapers, and is designed to accommodate a large amount of waste.

  Moreover, the absorber 4 which occupies the main part of the absorptive main body 5 is comprised by the amount of pulp material content of about half of the conventional paper diaper, and does not contain SAP at all. In addition, content of a pulp material should just be the quantity which does not exceed 10g, and SAP is applicable if it is the quantity of 10 weight% or less of the whole absorber. In this way, since SAP is not used at all and the amount of pulp material used is a small amount of about half of the conventional amount, even if it enters the water of a pool or the like, SAP does not flow out as before, The outflow of the pulp material can be suppressed to almost zero.

Further, since the amount of the pulp material used for the absorbent body 4 is small, the thickness of the product itself is reduced, so that there is no bulkiness even when worn, and the legs can be moved freely. According to the experiment by the present inventor, the thickness of the maximum thickness portion of the produced diaper 1, that is, the thickness of the substantially central portion of the absorbent main body 5, was measured to be 13.64 mm at a load load of 0.5 g / cm ^2. It was confirmed that the thickness was 7.48 mm at a load of 50 g / cm ² and the thickness was thin.

  Also, when the difference between the water retention amount of the diaper 1, that is, the weight before putting the diaper 1 into the water tank and after leaving it for 1 hour, it was 186 g, and it was confirmed that the water retention amount was high. It was.

  As described in detail above, the diaper 1 of the present embodiment is not different from a conventional paper diaper in appearance, but a waste collection pocket 13 is formed on the upper surface of the top sheet of the absorbent main body 5 by a three-dimensional gather 8, and a large amount Since the absorbent body 4 is composed of a small amount of pulp material and 10% by weight or less of SAP, even if the diaper 1 is worn and swimming or swimming, the excrement can be stored. Is stored in the excrement storage pocket 13 and is prevented from flowing out, and since the outflow of pulp material as well as SAP is surely prevented, there is an advantage that there is no worry of polluting water in a pool or the like. Furthermore, since the thickness of the absorber 4 is thin, there is an advantage that the freedom of the leg portion can be moved even when worn.

  Moreover, since the elastic elastic member 10 is arrange | positioned not only to the trunk part 9 but the side part 12, and the diaper 1 is worn in the state which tightened the side part 12 with the trunk part 9, the diaper in water It is possible to reliably prevent 1 from falling off. As a result, the wearer's free movement in water can be ensured, and the above-described SAP and excrement can be prevented from leaking out.

  Further, in the configuration of the present embodiment, as shown in FIG. 5, the three-dimensional gather 8 rises smoothly following the displacement of the diaper 1. That is, when worn without absorbing water, as shown in FIG. 5 (a), the space between the tips of the three-dimensional gathers 8 is widened and is in close contact with the wearer's skin in a folded state. Even in the case of deviation, as shown in FIG. 5 (b), the three-dimensional gather 8 rises up and follows smoothly because the folded portion of the three-dimensional gather 8 extends slightly while the tip of the three-dimensional gather 8 is in close contact with the skin. Furthermore, even if the amount of water absorption increases and the diaper 1 deviates considerably, the tip of the three-dimensional gather 8 can maintain a state of being in close contact with the wearer's skin, as shown in FIG. It is possible to reliably prevent the excrement in the excrement accommodation pocket 13 from leaking to the outside.

  On the other hand, in the conventional diaper configuration, when wearing water that does not absorb water, as shown in FIG. In addition, the side flap SF is in a state where the thighs are tightened, and when moisture is adsorbed to some extent, as shown in FIG. 6 (b), the three-dimensional gather 8 is raised while being dragged by the side flap SF. If the function is reduced, the amount of water absorption is increased, and the diaper is largely displaced, the tip of the three-dimensional gather 8 is separated from the skin of the wearer, and the function of the excrement accommodation pocket may be lost. Therefore, the configuration of the present embodiment is effective.

  As mentioned above, although one Embodiment applied to the diaper which uses this invention as a swimsuit was described, this invention can be used not only as a swimsuit but also as underpants worn under a swimsuit. Moreover, it cannot be overemphasized that the diaper concerning this invention can also be used as a general disposable pants type paper diaper or the disposable pants type diaper for training.

  The pants-type diaper for playing with water according to the present invention is such that the excrement of the wearer and the pulp material or SAP contained in the absorbent body constituting the absorbent main body do not flow out from the opening of the pants, etc. The wearer can move around freely and elastic elastic members are provided not only on the waistline but also on the side, so that the diaper can be prevented from slipping off underwater. It is useful for a disposable swimsuit worn for swimming or the like, or a disposable underpants worn under a swimsuit.

It is an external appearance perspective view of one Embodiment of the underpants type diaper for water play of the present invention. It is the perspective view which expanded and showed the diaper of the embodiment. It is the top view which expanded the diaper of the embodiment. It is XX arrow sectional drawing of FIG. It is behavior explanatory drawing at the time of water absorption in the diaper of the embodiment. It is behavior explanatory drawing at the time of water absorption in the diaper of a prior art example.
