A container for heating and cooking food includes: a lower containment body; an upper cover hermetically coupling with the lower containment body; and an automatic valve, in the shape of a cap, integrated in the upper cover, allowing steam to vent. The automatic venting valve includes: a control member controlling the pressure inside the container; and an elastic tongue associated and moulded in one piece with the control member. The control member is housed and rotatable in a recess in the upper cover. The elastic tongue has a deformed configuration, applying an elastic force pressing and closing the control member against a through hole in the bottom of the recess housing the control member, preventing the steam from exiting the container. When the steam pressure reaches a critical value, the control member rotates and tilts, removing the control member from the through hole, allowing the steam to vent.

A foam generator for compression receptacles is configured such that liquid contents pumped by an internal pressure as a result of directly compressing a compression receptacle, having the liquid contents stored therein, are mixed with air in a gas-liquid mixing chamber and, at the same time, directly discharged in the form of foam. Accordingly, the foam generator not only is capable of preventing the corruption of the liquid contents, which are not in contact with any separate metal member, but also further improves product responsiveness, since the contents are instantly discharged in the form of foam by compressing the compression receptacle.
