A dispenser is provided for liquids, the dispenser having a container and an outlet at a predetermined first level. The pressure in the container can be varied and a reservoir receives liquid from the outlet. A discharge passageway extends upwardly from the first level and terminates at a discharge opening at a second level, and an air relief opening is provided above the first level. The relief opening is no lower than the second level so that liquid displaced from the container flows into the reservoir and out of the passageway while air is trapped in the reservoir above the first level. consequently any gradual increase in temperature will cause air from the reservoir to be displaced through the air relief opening to minimize the risk of temperature driven dispensing.

A dispenser for liquids comprising: a resilient and deformable container for holding liquid at levels above a predetermined level; an outlet at a level below said predetermined level; a reservoir coupled to the container to form an assembly, the reservoir being in fluid communication with the container to receive liquid through said outlet and the reservoir having an air relief opening to permit pressure changes caused by temperature fluctuations to be equalized with atmospheric pressure; and a discharge passageway structurally connected to said assembly, the passageway being in fluid communication with the container to discharge liquid from the dispenser in response to deformation of the container.
