SHEET-LIKE COSMETIC PRODUCT
Document Type and Number:
WIPO Patent Application WO/2020/075634
Kind Code:
A1
Abstract:
This sheet-like cosmetic product (1) has sac-like first chambers (11, 21) and sac-like second chambers (12, 22) that are formed by bonding, at a joint portion (13), a front-side sheet member (31) and a rear-side sheet member which are both impervious to water. The first chambers (11, 21) each have housed therein a first ingredient (15) which undergoes a temperature increase when mixed with water; meanwhile, the second chambers (12, 22) each have housed therein a second ingredient (16) including water. The first chambers (11, 21) are separated from the second chambers (12, 22) by the joint portion (13) which includes weak joint sections (13E), and when the second ingredient (16) is pressed toward the first chambers (11, 21), weak joint sections (13E) get ruptured so as to cause the second ingredient (16) to be mixed into the first ingredient (15). The areas of the first chambers (11, 21) where the temperature increase take place accordingly, are configured to be attachable to the skin via a skin attachment layer.
