  • Patent number: 4072249
    Abstract: A container for dispensing fluid and semifluid liquids and pastes, such as for medicinal use, is provided with a top flexible dome and a bottom dome which may or may not be flexible. The contents which are stored in the space between the two domes is squeezed outwardly through a spout on the bottom dome by pressing and forcing the top dome into the bottom dome. The container may be combined with other containers which are connected along flanges of each container, which flanges are used to grip the container by fingers so that when the top dome is pressed downwardly by a thumb the fingers may aid in the process. The plurality of containers connected along the flanges form a block which may be combined with other blocks for easy transport.
