no. 1 Embodiment approach

[0035] refer to figure 1 and figure 2 , and the absorbent article according to the first embodiment will be described. figure 1 It is a plan view of the absorbent article 1 of embodiment. figure 2 yes figure 1 A cross-sectional view along line F1-F1' is shown.

[0036] figure 1 The absorbent article 1 is, for example, a sanitary napkin. Such as figure 1 As shown, the absorbent article 1 has a front region F, a central region M and a rear region R. As shown in FIG. The front region F is in contact with the skin surface on the ventral side of the wearer. The central region M is in contact with the skin surface around the wearer's vaginal opening. The rear region R is in contact with the skin surface of the wearer's buttocks.

[0037] The absorbent article 1 has a topsheet 10 that contacts the wearer's skin, a liquid-impermeable backsheet 20 that does not permeate liquid, and an absorber 30 . The absorbent article 1 has a material 100 between the top sheet 10 and the ...

no. 2 Embodiment approach

[0076] Next, the absorbent article 2 shown as 2nd Embodiment is demonstrated. The absorbent article 2 differs from the absorbent article 1 in the position where the cooling sensation material 100 is arranged in the thickness direction, but there is no difference in appearance, so the plan view is omitted. Figure 6 It is a cross-sectional view of the absorbent article 2 at the same position as the F1-F1' line of the absorbent article 1 . Figure 7 It is a cross-sectional view of the absorbent article 2 at the same position as the F2-F2' line of the absorbent article 1 . Such as Figure 6 , Figure 7 As shown, in the absorbent article 2, between the absorbent body 30 and the back sheet 20 and at an area equivalent to figure 1 In the position of the region T shown, there is a region where the amount of the cooling sensation material 100 per unit area is large.

[0077]In order to function as an indicator more effectively, the cooling sensation material 100 is preferably arra...

no. 3 Embodiment approach

[0084] Next, the absorbent article 3 shown as the third embodiment will be described. The absorbent article 3 differs from the absorbent article 1 in the position in which the cooling sensation material 100 is arranged in the thickness direction, but there is no difference in appearance, so a plan view is omitted. Figure 10 It is a sectional view of the absorbent article 3 at the same position as the F1-F1' line of the absorbent article 1 . Figure 11 It is a sectional view of the absorbent article 3 at the same position as the F2-F2' line of the absorbent article 1 . Such as Figure 10 , Figure 11 As shown, the absorbent article 3 is inside the absorbent body 30 and is equivalent to figure 1 In the position of the region T shown, there is a region where the amount of the cooling sensation material 100 per unit area is large. That is, the cooling sensation material 100 is mixed with hydrophilic fibers, polymer absorbents, etc. constituting the absorber 30 .

Abstract

An absorbent article includes a top sheet having a contact surface that comes into contact with the wearer's skin, a liquid-impermeable back sheet that does not pass through liquid, and an absorbent body disposed between the top sheet and the back sheet. The absorbent article has a cooling material containing a cooling agent between the surface sheet or the surface sheet and the back sheet. On the outer side of the surface sheet in the plane direction of the contact area with the wearer's excretion part, the amount of the cooling-feeling material per unit area is greater than the amount of cooling-feeling material per unit area in the contact area. High volume areas.

Description

technical field [0001] The present invention relates to an absorbent article having a top sheet, a back sheet, and an absorbent body. Background technique [0002] Conventionally, in absorbent articles such as disposable diapers, a cooling agent that gives a cooling sensation to the wearer is disposed on the skin-contacting surface that contacts the wearer's skin (see Patent Document 1). The cooling agent is covered with a water-soluble microencapsulation agent, and is placed on the skin-contacting surface that contacts the wearer's skin. When the film is dissolved by the wearer's urine, the components of the cooling agent diffuse and come into contact with the wearer's skin to cause irritation. In this way, the wearer is made aware of when to change the diaper. [0003] In addition, an absorbent article is disclosed that not only has the above-mentioned function of suggesting "replacement timing", but is also coated with a substance that gives the wearer a refreshing feel...
