ABSTRACT OF THE DISCLOSURE A container for liquids, semi-liquids, powders and similar flowable fluids comprises a substantially airtight body for storing the fluid, a means for varying the pressure of gas above the level of the fluid in the body of the container, e.g resilient flexible container walls such as a squeeze bottle, an air pocket structure disposed at the lower end of the container, and in free fluid communication with the body of the container so as to allow entry of fluid from the body of the container into the air pocket structure. Air resides in the air pocket structure when the container is disposed with its lower end downwardly. An outlet passageway has an upper end which communicates near the top of the air pocket structure to be disposed in air retained in the air pocket and a lower end open to atmosphere exteriorly of the container and the air pocket. Such a container holds liquids therein without dripping. To discharge the liquid or other fluid the pressure on the body is increased, so as to cause liquid to rise through the air pocket into the outlet passageway, and to issue therefrom. Upon release of the applied pressure, air is sucked back in through the passageway so as to have a cleaning effect thereon. The structure allows storage of liquid ready for dispensing, but without risk of leakage or dripping, even when exposed to fluctuations in temperature of considerable magnitude.
