It is aa sectional drawing in the top view seen from the skin contact surface side of the absorptive article concerning a 1st embodiment of the present invention. It is a figure for explaining the state where the absorptive article concerning a 1st embodiment of the present invention was worn on underwear. It is a figure for explaining the state where the absorptive article concerning a 1st embodiment of the present invention was worn on underwear.

(First embodiment of the present invention)
With reference to FIG. 1 thru | or FIG. 3, the absorbent article 1 which concerns on the 1st Embodiment of this invention is demonstrated. For example, the absorbent article 1 according to the present embodiment is a panty liner, an incontinence pad, a sanitary napkin, or the like.

  The top view seen from the skin contact surface side of the absorbent article which concerns on FIG. 1 at the 1st Embodiment of this invention is shown, and the skin of the absorbent article which concerns on the 1st Embodiment of this invention in FIG. The aa sectional view in the top view seen from the contact surface side is shown.

  As shown in FIG. 2, the absorbent article 1 according to this embodiment is disposed between a liquid-permeable top sheet 11, a liquid-impermeable back sheet 12, and the top sheet 11 and the back sheet 12. The absorber 2 is provided.

  In the absorbent article 1 according to this embodiment, a second sheet may be disposed between the top sheet 11 and the absorbent body 2.

  The absorbent body 2 is constituted by pulverized pulp and a superabsorbent polymer and a core wrap that wraps both. Here, the superabsorbent polymer is a granular polymer of a cross-linked sodium polyacrylate.

  A core wrap is a sheet of any material that absorbs liquid. For example, a tissue may be used as the core wrap, or an air laid sheet in which hydrophilic fibers or pulverized pulp is formed into a sheet shape by the air laid method may be used.

  Moreover, as shown in FIG. 1, the absorbent article 1 according to the present embodiment may be provided with a plurality of compressed grooves 21, 22, and 23. Here, the pressing grooves 21, 22, and 23 are configured to squeeze from the top sheet 11 to the absorber 2.

  Moreover, the absorbent article 1 which concerns on this embodiment has a pair of wing part 41 currently formed so that it may extend to the both outer sides of the width direction W of the absorbent article 1, as shown in FIG. It may be. Furthermore, the absorbent article 1 according to the present embodiment may have a pair of hip flap parts 42 behind the wing part 41 in the longitudinal direction L of the absorbent article 1.

  Here, in the wing part 41 and the hip flap part 42, an adhesive for fixing the absorbent article 1 to the underwear is applied to the clothes contact surface side of the back sheet 12.

  Moreover, in the absorbent article 1 which concerns on this embodiment, as shown in FIG.1 and FIG.2, it absorbs more than the area | region where the absorber 2 is provided between the surface sheet 11 and the back surface sheet 12. As shown in FIG. Heating elements 3A and 3B are arranged outside the longitudinal direction L of the article 1.

  Examples of the heating elements 3A and 3B include those used in known disposable warmers, and those made of iron powder, activated carbon, and sodium chloride can be used. As the sheet for wrapping the composite powder, a sheet having air permeability and preventing leakage of the powder is preferable. For example, a moisture permeable film, a melt blown nonwoven fabric, or the like is preferably used.

  In the absorbent article 1 according to the present embodiment, the heating elements 3A and 3B are arranged on the front side and the rear side in the longitudinal direction L of the absorbent article 1 relative to the region where the absorbent body 2 is provided. Alternatively, the heating element 3A may be arranged only on the front side in the longitudinal direction L of the absorbent article 1 relative to the region where the absorber 1 is provided.

  Further, the periphery of the absorbent article 1 is joined with an adhesive or a seal to form a seal portion 24, and the heating elements 3A and 3B and the absorbent body 2 are also joined with an adhesive or a seal, Seal portions 25A and 25B are formed. The seal portions 25A and 25B can prevent the steam generated from the excrement and moisture absorbed by the absorber 2 from being directly warmed by the heating elements 3A and 3B.

  Further, in the region where the heating elements 3A and 3B are provided, an adhesive for fixing the absorbent article 1 to the undergarment may be applied to the clothing contact surface side of the back sheet 12.

  3 and 4 show a state in which the absorbent article 1 according to the present embodiment is worn on the underwear 100. FIG.

  When the wearer wears the absorbent article 1 on the underwear 100, the wing part 41 is wound around the crotch of the underwear, the hip flap part 42 is spread on the underwear 100, and the absorbent article 1 is fixed to the underwear 100. .

  As shown in FIG. 3, the heating elements 3 </ b> A and 3 </ b> B may be configured to be fixed to the inner surface of the underwear 100 when the absorbent article 1 according to this embodiment is worn on the underwear 100. .

  Further, as shown in FIG. 4, the heating elements 3 </ b> A and 3 </ b> B are configured to be fixed to the outer surface of the underwear 100 in a state where the absorbent article 1 according to this embodiment is worn on the underwear 100. Also good.

  According to the absorbent article 1 according to the present embodiment, since the heating element 3A, 3B is configured not to be disposed in the region where the absorber 1 is provided, the absorber that has absorbed body fluid is warmed. It is possible to warm the wearer's uterus and reduce menstrual pain without causing stuffiness on the skin of the wearer and the surface of the top sheet 11 due to the above.

  Moreover, according to the absorbent article 1 which concerns on this embodiment, since heat generating body 3A, 3B is united with the absorbent article 1, when a wearer becomes 3 A, 3B heating element 3A, 3B has become no longer warm. It can be noticed that it is time to replace the absorbent article 1.

  Although the present invention has been described in detail using the above-described embodiments, it is obvious to those skilled in the art that the present invention is not limited to the embodiments described in this specification. The present invention can be implemented as modified and changed modes without departing from the spirit and scope of the present invention defined by the description of the scope of claims. Therefore, the description of the present specification is for illustrative purposes and does not have any limiting meaning to the present invention.
