The specific embodiment

(first embodiment of the present utility model)

Referring to figs. 1 through Fig. 6, the absorbent commodity 1 of first embodiment of the present utility model is described.For example, the absorbent commodity 1 of present embodiment is panty-liners, incontinence pad, sanitary napkin etc.

Fig. 1 shows the vertical view of observing the absorbent commodity of first embodiment of the present utility model from the skin contact side, Fig. 2 shows the a-a profile of vertical view of observing the absorbent commodity of first embodiment of the present utility model from the skin contact side, Fig. 3 shows the b-b profile of vertical view of observing the absorbent commodity of first embodiment of the present utility model from the skin contact side, and Fig. 4 shows the c-c profile of vertical view of observing the absorbent commodity of first embodiment of the present utility model from the skin contact side.

As Fig. 2 to shown in Figure 4, the absorbent commodity 1 of present embodiment have the surface patch 1 of liquid permeability, opaque liquid back sheet 12, be disposed at the absorber 2 between surface patch 11 and the back sheet 12.

In addition, in the absorbent commodity 1 of present embodiment, between surface patch 11 and absorber 2, also can dispose second.

Absorber 2 is made of the core retainer plate of absorber core and parcel absorber core, and above-mentioned absorber core constitutes by pulverizing slurry and macromolecule absorbing polymeric.Here, high molecular polymer is the granulous polymer of sodium acrylate copolymer.

In addition, core retainer plate is the thin slice of any materials of absorption liquid.For example,, can use thin paper, also can use by the air lay method to make hydrophilic fibre or pulverizing slurry form laminar air lay thin slice as the core wrappage.

In addition,, the hot-wind nonwoven cloth that constitutes by polyethylene, polypropylene, the such polyolefine fiber of polyethylene terephthalate or the polyethylene film of perforate can be used,, polyolefin film can be used as back sheet 12 as surface patch 11.

In addition, as second, can use the hot-wind nonwoven cloth that constitutes by polyethylene, polypropylene, the such polyolefine fiber of polyethylene terephthalate.

In addition, on the absorbent commodity 1 of present embodiment, alongst L is provided with leakproof wall (not shown).

Here, the leakproof wall can constitute by the thread elastomeric element that configuration on the non-woven fabrics base materials such as spunbond or SMS that are made of polyethylene, polypropylene, the such polyolefine fiber of polyethylene terephthalate is extended.

In addition, in the absorbent commodity 1 of present embodiment, as shown in Figure 1, a plurality of compression grooves 21,22,23 can be set.Here, compression groove 21,22,23 constitutes in the mode that is pressed onto from surface patch 11 till the absorber 2.

Here, in the zone that absorber 2 is set, the clothes contact surface side of sheet 12 is coated with the binding agent 50C that is used for absorbent commodity 1 is fixed in underwear overleaf.As this binding agent 50C, do not adopt the binding agent of phenylethylene, but the preferred binding agent that adopts based on propylene class binding agent or olefines binding agent.

In addition, the absorbent commodity 1 of present embodiment also can have a pair of alar part 41 as shown in Figure 1, and this a pair of alar part 41 forms in the extended mode in two outsides to the width W of absorbent commodity 1.In addition, the absorbent commodity 1 of present embodiment also can have a pair of buttocks wing flap portion 42 on the length direction L of absorbent commodity 1 and at the rear of alar part 41.

Here, in alar part 41 and buttocks wing flap portion 42, the clothes contact surface side of sheet 12 is coated with binding agent 50D and the 50E that is used for absorbent commodity 1 is fixed in underwear overleaf.As this binding agent 50D and 50E, do not adopt the binding agent of phenylethylene, but preferred binding agent based on propylene class binding agent or olefines binding agent.

In addition, in the absorbent commodity 1 of present embodiment, as depicted in figs. 1 and 2, between surface patch 11 and back sheet 12, and, comparing the position in the outside that the zone that absorber 2 is set is in the length direction L of absorbent commodity 1, configuration heater 3A, 3B.

Heater 3A, 3B for example are the middle heaters that use such as known disposable body warmer, can use the heater that is made of iron powder, active carbon and sodium chloride.Thin slice as this composite powder of parcel preferably has breathability and can prevent the material that powder spills, and for example, is fit to use poisture-penetrability thin film or melt spraying non-woven fabrics etc.

In addition, in the absorbent commodity 1 of present embodiment, can compare, be positioned at the front side of length direction L of absorbent commodity 1 and the position of rear side with the zone that absorber 2 is set, configuration heater 3A, 3B, also can be only comparing, be positioned at the position of front side of the length direction L of absorbent commodity 1, configuration heater 3A with the zone that absorber 2 is set.

In addition, engage by binding agent or sealing around the absorbent commodity 1, form sealing 24, in addition, also engage between heater 3A, 3B and the absorber 2, form sealing 25A, 25B by binding agent or sealing.By 25A of sealing portion and 25B, can prevent that steam that the Excreta that absorbed by absorber 2 or moisture produces is by heater 3A, 3B direct heating.

In addition, in the zone that heater 3A, 3B are set, the clothes contact surface side of sheet 12 is coated with the binding agent 50A and the 50B that are used for absorbent commodity 1 is fixed in underwear overleaf.As this binding agent 50A and 50B, do not adopt the binding agent of phenylethylene, but preferred binding agent based on propylene class binding agent or olefines binding agent.

Fig. 5 and Fig. 6 represent the absorbent commodity 1 of present embodiment is worn in the state of underwear 100.

The wearer is involved in the crotch portion of underwear with alar part 41 when wearing absorbent commodity 1 in underwear 100, buttocks wing flap portion 42 is launched on underwear 100, by binding agent 50C to 50E absorbent commodity 1 is fixed in underwear 100.

Heater 3A, 3B also can constitute as follows, that is, as shown in Figure 5, wear under the state of underwear 100 at the absorbent commodity 1 of present embodiment, are fixed in the medial surface of underwear 100 by binding agent 50A.

In addition, heater 3A, 3B also can constitute as follows, that is, as shown in Figure 6, wear under the state of underwear 100 at the absorbent commodity 1 of present embodiment, are fixed in the lateral surface of underwear 100 by binding agent 50B.

According to the absorbent commodity 1 of present embodiment, as binding agent 50A to 50E, use with propylene class binding agent or olefines binding agent binding agent as main body, so, the situation that the viscosity that can avoid binding agent 50A to 50E reduces owing to heater 3A and 3B.

More than, use above-mentioned embodiment that this utility model is had been described in detail, still, to those skilled in the art, the embodiment that this utility model is not limited only to illustrate in this description is conspicuous.This utility model can be implemented with correction and variant under the situation of purport of the present utility model that record limited that does not break away from claim and scope.Therefore, the record of this description is to be illustrated as purpose with example, and does not mean that this utility model is carried out any restriction.
