Abstract
The invention provides dispensers for liquids having a dispensing opening in the side of the dispenser and liquid is stored in a main body of a resiliently deformable container coupled to a neck structure which has a bottom outlet inside a base structure. In use, the dispenser is first lifted and then tilted through about 30 to 50 degrees before squeezing the container. The tilting action causes some of the air in the base structure to be trapped thereby minimizing the effect of temperature compensation on response rate. Consequently, the squeezing action is immediately available to force liquid to pass through the base structure and issue from the side dispensing opening. Various structures can be made consistent with the invention to accommodate a range of liquids having different properties.
