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.
Claims7
A sealed dispensing container for a liquid medicament comprising a unitary molded container including:
- A. an elongated continuously curvilinear middle portion;
- B. a hemi-ellipsoidal portion closing one end of said middle portion;
- C. a truncated conical portion having its larger end connected to said middle portion opposite said hemi-ellipsoidal portion;
- D. a substantially cylindrical portion connected to said truncated conical portion;
- E. a first integral tab closing one end of said cylindrical portion;
- F. a second integral tab connected to said hemi-ellipsoidal portion;
- whereby when said first and second tabs are rotated in opposite directions said cylindrical portion shears adjacent said first tab defining a discharge orifice.
A dispensing container as defined in claim 3 wherein the diameter of said cylindrical portion is about four millimeters and the liquid medicament is retained after said first tab is removed until a compressive force is applied to the container.
