Description

  The present invention relates to an absorbent article.

  There are various types of adult disposable diapers, such as a tape stop type, a urine picking pad, and a pants type. These disposable diapers are appropriately selected according to the necessity of care in excretion of the wearing subject.

  By the way, tape diapers and pants-type disposable diapers may be used alone or in combination with a urine-absorbing pad inside. Is almost. The reason is that the cost per sheet of disposable diapers is high. For this reason, the absorbent article (urine collection pad) provided with the liquid-permeable top sheet, the liquid-impermeable back sheet, and the absorber interposed therebetween is used on the top sheet of the disposable diaper. Yes. That is, after excrement is absorbed and held by the urine absorbing pad, only the urine absorbing pad is replaced, and therefore, it is only necessary to replace the inexpensive urine absorbing pad after excretion, and it can be used economically.

  In addition, pants-type disposable diapers are intended for people who can walk or move by themselves to promote independence of excretion, and are literally in the shape of pants. However, when a pants-type disposable diaper is used as an outer and a urine collecting pad is used as an inner, the wearer of the disposable diaper can move relatively. There is a risk that it will end.

  In order to solve this problem, Patent Document 1 or 2 discloses a technique in which hooking means for hook-and-loop fasteners is provided on the clothing side surface of the urine absorbing pad. Patent Document 1 has a liquid-permeable top sheet, a liquid-impervious back sheet, and a liquid-absorbent core interposed between the two sheets, and is removably fastened to the inner surface of the clothes on the back sheet. Disposable bodily fluid treatment articles having a mounting member that can be made are disclosed.

  Further, Patent Document 2 discloses that a pair of dorsal hook tapes having hook-shaped protrusions and having a long shape on the back side of the back surface of the liquid-impervious backsheet are hems from the dorsal side to the ventral side. An absorbent pad is disclosed that is disposed and secured to form a broadened C-shape.

  On the other hand, a pad dedicated to pants, which is used as an inner pants-type diaper, has also been developed. When using a pad in a pants-type paper diaper, fix the pad in the pants-type paper diaper in advance and put the pant on or in the middle of lifting the pants through your feet to your waist And the method of pulling up the pants on the side and wearing it is adopted. However, since wearing for pants is performed by the wearer or the caregiver and is smaller than a normal urine collecting pad, leakage or uncomfortable feeling will occur if not worn at an appropriate position.

  For this reason, Patent Document 3 includes an absorbent pad provided with a back sheet having a first engagement portion and an absorption pad holder having a second engagement portion, and the first engagement portion and the second engagement portion. And the absorbent pad holder are proposed by attaching the absorbent pad to the absorbent pad holder.

  According to Patent Document 3, an absorbent article in which the absorbent pad does not shift can be provided. However, when not using the paper diaper main body which is the said absorption pad holding body, it is necessary to join the member equivalent to a 2nd exclusive engagement part as an accessory to another paper diaper main body. For this reason, since the user himself has to perform positioning and the like of the second engaging portion, it is not preferable because it takes time to use.

(Configuration of absorbent article)
As shown in FIGS. 2 and 3, the absorbent article 10 includes a liquid-permeable top sheet 11 disposed on the skin contact surface side, and a liquid-impermeable back disposed to face the top sheet 11. The sheet | seat 12 and the absorber 13 arrange | positioned between the top sheet | seat 11 and the back sheet | seat 12 are provided. Thereby, the absorber 13 has a structure sandwiched between the top sheet 11 and the back sheet 12. In addition, the absorbent article 10 has tab portions 14 that extend in the longitudinal direction at both ends of the top sheet 11 in the longitudinal direction.

(Top sheet)
The top sheet 11 is a part that allows body fluid to pass quickly toward the absorber 13, and is disposed to face the back sheet 12 with the absorber 13 interposed therebetween. Since the top sheet 11 is a sheet that comes into contact with the skin, it is a soft touch and does not irritate the skin, for example, a nonwoven fabric such as a thermal bond nonwoven fabric typified by an air-through nonwoven fabric, a thermal bond / span It is formed from a material such as a composite nonwoven fabric in which bonds are laminated, an open film such as an open polyethylene film, a foam film such as polyethylene foam or urethane foam, or a composite sheet in which these are laminated. The top sheet 11 may be provided as a single layer or a plurality of layers, and a plurality of through holes may be formed in order to impart dry touch properties. As the nonwoven fabric, synthetic fibers such as polyethylene, regenerated fibers such as rayon, and natural fibers such as cotton can be used which are produced by a known processing method such as a spunlace method or a spunbond method. In order to reduce irritation to the skin, the top sheet 11 may contain a lotion, an antioxidant, an anti-inflammatory component, a pH adjuster, an antibacterial agent, a moisturizing agent, and the like.

(Absorber)
The base material of the absorbent body 13 is not particularly limited as long as it is generally used for absorbent articles such as sanitary napkins, paper diapers, and urine pads. For example, fluff pulp, cotton, rayon, acetate, tissue, absorption It is formed from materials such as paper and hydrophilic nonwoven fabric. Among these, fluff pulp is preferable from the viewpoint of absorbability to body fluids. In addition, as a material of fluff pulp, there are wood pulp, synthetic fiber, polymer fiber, etc. and non-wood pulp defibrated in a cotton shape. Moreover, the base material of the absorber 13 contains a superabsorbent polymer (SAP: Super Absorbent Polymer). Examples of the superabsorbent resin include crosslinked polyacrylate, self-crosslinked polyacrylate, saponified acrylate-vinyl acetate copolymer crosslinked, isobutylene / maleic anhydride copolymer crosslinked, polysulfone Examples thereof include cross-linked acid salts, and partially cross-linked water-swellable polymers such as polyethylene oxide and polyacrylamide. Among these, as the highly water-absorbing resin, a polyacrylate-based resin excellent in water absorption and water absorption speed is preferable.

  The base material and SAP of the absorber 13 are preferably formed by mixing SAP particles in the base material, or an SAP sheet in which superabsorbent polymer particles are fixed between the base materials.

  Further, the absorbent article 10 includes a pair of three-dimensional gathers 17 having a three-dimensional gather elastic member along the longitudinal direction of the absorbent article 10 in order to prevent side leakage of body fluid excreted by the user.

(Back sheet)
The back sheet 12 is a liquid-impermeable sheet material that prevents body fluid from leaking to the outside of the absorbent article 10, and a water-permeable sheet material is used. However, the back sheet 12 may have moisture permeability to prevent stuffiness. . The back sheet 12 includes a nonwoven fabric, a breathable polyolefin film laminated on the nonwoven fabric, and a hot melt adhesive between the nonwoven fabric and the breathable polyolefin film and intermittently bonds them.

  As a nonwoven fabric used for the back sheet 12, a raw material, a manufacturing method and the like are not particularly limited. For example, a spunbond nonwoven fabric, a thermal bond nonwoven fabric, a spunbond nonwoven fabric, a meltblown nonwoven fabric, a spunbond made of synthetic fibers such as polypropylene, polyethylene, and polyester. A composite nonwoven fabric in which nonwoven fabrics are laminated can be used.

  The breathable polyolefin film laminated on the nonwoven fabric is not particularly limited as long as it has waterproofness and moisture permeability. For example, a film is formed by melt-kneading a polyolefin resin and an inorganic filler such as calcium carbonate. And the thing which embossed the porous film obtained by uniaxially or biaxially stretching this film and the polyolefin-type film is mentioned. In addition, as polyolefin resin, polyethylene, polypropylene, polybutene, and these can be used individually or in mixture. The breathable polyolefin film is preferably a highly breathable polyethylene film from the viewpoint of water resistance and breathability.

  There are no particular restrictions on the hot melt adhesive, for example, synthetic rubbers such as styrene / butadiene / styrene copolymers, styrene / isoprene / styrene copolymers having a melting point of 100 ° C. to 180 ° C., or And olefin-based hot-melt adhesives such as ethylene-vinyl acetate copolymer. Of these, one kind or a plurality may be blended.

(Tab part)
The base material of the tab portion 14 is a resin film such as polyethylene, polyolefin, or polystyrene, or a nonwoven fabric, and is preferably formed from a spunbond nonwoven fabric. Moreover, the tab part 14 is extended in the longitudinal direction in the both ends before and behind the longitudinal direction of the absorbent article 10, and is provided in the center part of the width direction. The tab portion 14 is affixed to the back sheet 12 by an adhesive such as hot melt, heat sealing, or the like. Further, the tab portion 14 has a locking means 15 formed on the non-skin contact surface side of the absorbent article 10.

  The locking means 15 extends from the longitudinal end of the tab portion 14 toward the central portion of the absorbent article 10. The locking means 15 is not particularly limited as long as it is a material that can be locked to the outer 1 such as an adhesive or an adhesive, but a hook-and-loop fastener that can be easily attached to and detached from the outer 1 is preferable. By this locking means 15, the skin contact surface of the outer 1 and the absorbent article 10 are locked. By providing the tab portion 14 in this way, the tab portion 14 becomes a mark of the center line, and the position of the tab portion 14 is easily understood and aligned even when the wearer is viewed from the front side. Therefore, it is possible to easily bond the absorbent article 10 so as to be positioned at the center portion of the outer 1 in the width direction. The shape of the locking means 15 is preferably a substantially rectangular shape with a uniform locking surface, but is not particularly limited and can be changed as appropriate.

  A tab 16 is provided at the end of the tab 14 in the longitudinal direction. By providing the knob portion 16 in this manner, it becomes a knob when the outer member 1 and the locking means 15 of the absorbent article 10 are peeled off and is easily peeled off.

  Further, since a force can be directly applied to the locking means 15, the position can be easily adjusted at the time of mounting, and the crimping at the time of locking can be accurately performed on the locking means 15. As in the case where there is a locking means on the back surface (non-skin contact surface) found in conventional absorbent articles, it is possible to reduce the trouble of crimping a wide range by groping. In addition, the absorbent article 10 and the outer 1 can be prevented from being damaged because an inappropriate portion of the absorbent article 10 is not grabbed or peeled in an inadvertent direction.

  Next, the disposal method of the absorbent article 10 will be described. FIG. 4 is a perspective view showing a discarded state of the absorbent article 10 according to the embodiment of the present invention. As shown in FIGS. 4 (a) and 4 (b), the top sheet 11 is folded inward or rounded when it becomes unnecessary due to replacement of the absorbent article 10 or the like. Then, the locking means 15 of the tab portion 14 formed on the non-skin contact surface side is folded back and locked to the back sheet 12. By forming the material of the back sheet 12 from a nonwoven fabric and a breathable polyolefin film laminated on the nonwoven fabric, the locking means 15 is bonded to the outermost nonwoven fabric. Therefore, it can be discarded with the non-skin contact surface of the absorbent article 10 and can be treated hygienically. As shown in FIG. 4C, the locking means 15 does not have to be provided at the position where the tab portion 14 is folded back. Thus, by not providing the latching means 15 at the folding position, the latching means 15 can be easily folded.

(Effect of embodiment)
As described above, the absorbent article 10 according to the present embodiment includes a liquid-permeable top sheet 11, a liquid-impermeable back sheet 12 disposed to face the top sheet 11, and the top sheet 11.
