  • Patent number: 3993223
    Abstract: A sealed dispensing container for liquid medicaments is described which may be readily opened by a twisting force applied on opposite ends of the container. All of the parts of the container making up a chamber for the medicament are shaped to be substantially completely flattened by the application of a compressive force, such as that applied by thumb and forefinger, to completely discharge the liquid medicament. After the container is opened, the liquid will be retained in the container in the absence of a compressive force and regardless of the orientation of the container in a horizontal or inverted position.
