Single dose disposable container

An improved unit-dose disposable container of molded plastic to be manually opened, without the need for accessories, for dispensing liquid medicines and the like, said container being molded as an integral piece so that its several parts disposed along a central longitudinal axis of the container are of sequentially narrower widths, said sequential parts consisting of:

• a wide flexible body to be compressed for expelling the contents of the container;
• a narrow, more rigid nozzle to be held with the thumb and finger on opening the container, and an even narrower, solid tip portion of substantially constant cross-section;
• at least said wide flexible body and said nozzle portion defining therein a hollow cavity for receiving the liquid for dispensing from the container;
• said tip portion being of sufficient length for holding with the thumb and finger and having sufficient cross-section area and having an outer gripping contour of a polygonal cross-section to form three or more graspable flat sides so that, while gripping the tip, oppositely directed motion between the thumb and finger along a path transverse to the longitudinal axis of the container imparts a rotating movement to the tip about said longitudinal axis sufficient to break off said tip at a point adjacent the joining of the tip and the nozzle whereby to open the container and to permit expelling its contents through a resulting dispensing orifice communicating with the hollow cavity, said rigid nozzle having sufficient wall thickness that when gripped the container is maintained in a secure and steady condition during the breaking-off of the tip portion.
