A self-cooling container including a combined valve cup and bottom assembly (10) for securely engaging the HEU (16) to the can bottom where user activation occurs. The valve (22) is crimped directly into the valve cup (34) on the combined valve cup and bottom assembly. The HEU is then attached to the combined valve cup and bottom assembly of the present invention for cooling of the beverage as will be explained further herein. Preferably, the combined valve cup and bottom assembly is integrally attached to the body or side wall of the container, thereby forming a two-piece assembly. Alternatively, the combined valve cup, valve and bottom assembly is attached by crimping to the body or side wall of the container, thereby forming a three-piece assembly.

La soupape (22) est sertie directement dans la coupelle (34) de soupape dudit système combiné. L'unité d'échange thermique est ensuite fixée au système combiné décrit dans la présente invention, et assure le refroidissement de la boisson de la manière indiquée dans la description. Le système combiné de fond et de coupelle de soupape est de préférence fixé en seul bloc au corps ou à la paroi latérale du conteneur, ceci de manière à former un assemblage en deux éléments.
