The foam generator for inverted compression receptacles according to the present invention is configured such that liquid contents pumped by an internal pressure as a result of directly compressing an inverted compression receptacle (100), having the liquid contents stored therein, are mixed with air in a gas-liquid mixing chamber (S) and, at the same time, directly discharged in the form of foam. That is, direct compression of the inverted compression receptacle (100) allows the liquid contents to be instantly discharged in the form of foam, thereby further improving product responsiveness. In particular, the present invention is capable of further improving the convenience of use thereof, since the contents can be discharged in the form of foam by directly compressing the inverted compression receptacle (100) merely with one hand. In addition, the foam generator for inverted compression receptacles according to the present invention allows the discharged foam to be applied to or cleanse skin by means of a message member (900) having massage bristles (930) attached thereto. In particular, the present invention is capable of producing a messaging effect while allowing the discharged foam (contents) to be directly and evenly applied to the skin by means of the message member (900) even without the use of palms.
