摘要：
The present invention relates to hand-held beverage dispensing devices, and in particular to baby feeding bottles and drinking beakers and to disposable beverage containers such as plastic vessels for warm or hot beverages. The hand-held beverage dispensing device (201 ) comprises a container (202), the container having an internal volume (204) for holding a quantity of a beverage (206), a dispensing outlet (108) through which the beverage can be consumed by a person drinking from the device, and also a temperature sensitive valve mechanism (118, 216, 220) for controlling the flow of beverage from the internal volume to the dispensing outlet. This mechanism has a movable valve element in the form of a diaphragm (216), a valve seat (218), and an actuating means (220) for driving the movement of the diaphragm (216) depending on the temperature of the beverage held within the container. The actuating means, distensible diaphragm and valve seat are configured such that, in use, the actuating means causes the diaphragm to distend to engage with the valve seat when the temperature of the beverage is above a threshold temperature to close the flow of the beverage from the internal volume to the dispensing outlet. The actuating means (220) comprises a housing (230) and an expandable volume of gas (232). The diaphragm (216) is joined to the housing to form a gas-tight enclosure which contains this volume of gas. In use, heat (250) flows between the beverage (206) and the gas (232) to cause corresponding changes in the temperature and volume of gas resulting in movement of the diaphragm owing to changes in the distension of the diaphragm. The movement of the diaphragm causes the diaphragm to engage with the seat when the temperature of the beverage is above the threshold temperature to close the flow of the beverage from the internal volume to the dispensing outlet.La présente invention se rapporte à des dispositifs de distribution de boisson portatifs, et en particulier à de
