Abstract: The present invention is to provide a self-inflating sexual aid, which includes a closed bag having an airtight sealed edge while a receiving space is formed therein, and a reactive powder and a sachet containing a reactive liquid inside the receiving space. When squeezed, the reactive liquid flows out of the sachet and contacts with the reactive powder to produce gaseous carbon dioxide and enable the closed bag to be automatically and instantly inflated to a completely taut state. An elastic cover has an inner surface that can be fitted closely over an outer surface of a rod-shaped portion of the closed bag, thus forcing the corresponding airtight sealed edge to lie smoothly against the outer surface of the rod-shaped portion. Consequently, a user can hold a handle portion of the closed bag and use the sexual aid by maneuvering the rod-shaped portion of the closed bag.

Abstract: This invention discloses a three-dimensional inflatable card including a card body having a containing space defined therein, an opening formed on each of two corresponding sides of the containing space, and a movable portion disposed on the card body at a position corresponding to a side of the containing space; an airbag adhered on the card body within the containing space, and containing a reacting powder and an acid solution pack; and a protective ring disposed around the periphery of the airbag, and having a thickness sufficient to contain the acid solution pack; wherein an acid solution in the acid solution pack is able to chemically react with the reacting powder to produce gas for enabling the airbag to expand to a predetermined volume, break the movable portion, and extend to the outside of the containing space, so as to form a three-dimensional inflatable object on the card body.
