A beverage container (10, 92, 174) for hot liquids which has a vessel (12, 94, 176) with a completely enclosed, thermally insulated, internal chamber (14, 96, 182) within which is to be placed a quantity of consumable hot liquid (86, 114, 184). A cap (26, 106, 212) is removably mounted on the vessel which is to completely close the internal chamber. A dispensing passage (84, 136, 228) extends from the internal chamber to the cap with a valve (78, 126, 230) mounted within the cap. Air pressure is to be supplied into the internal chamber which causes a small portion of the hot liquid to be conducted through the passage, past the valve, and into a reservoir (34, 118, 208) mounted in conjunction with the cap. The reservoir is open to the ambient. The pumping of the air into the internal chamber can be accomplished by a bellows assembly (54, 200) or a hand operated piston (146) and cylinder (144) arrangement.
L'invention concerne un récipient pour boissons chaudes (10, 92, 174) possédant un compartiment (12, 94, 176) qui comprend une chambre interne totalement close à isolation thermique (14, 96, 182), ladite chambre renfermant une certaine quantité d'un liquide chaud destiné à la consommation. Un bouchon (26, 106, 212) est monté amovible sur le compartiment, qui obture complètement la chambre interne. Un canal de distribution (84, 136, 228) s'étend entre la chambre interne et le bouchon. Une soupape (78, 126, 230) est intégrée audit bouchon. Sous l'effet de la pression de l'air introduit dans la chambre interne, une petite portion de liquide chaud passe à travers le canal, franchit la soupape et s'écoule dans un réservoir (34, 118, 208) monté conjointement avec le bouchon. Le réservoir communique avec l'air ambiant. On peut pomper l'air dans la chambre interne au moyen d'un ensemble de soufflets (54, 200) ou d'un dispositif manuel à piston (146) et à cylindre (144).
