ABSTRACT:
A tip-off cap and closure for a container, for closure thereof, and sealing of the contents therein. The cap includes a narrow elongated exterior top portion, a peripherally enlarged open bottom skirt at the bottom thereof, and a container closure for an access opening, operatively disposed within the skirt and operatively integrated therewith. The integrated cap and closure are conjointly removable from the container, to open the container for access to the liquid therein, by application of a lateral tilting force against the narrow, elongated cap exterior at a position thereof remote from connection of the cap to the container. Removal of the integrated cap and closure seal means from the container is normally effected without breakage of the material forming the container. The cap and closure act as a unit assembly when being removed. The construction is designed to generally assimilate currently known and used glass ampules for medicaments, in configuration and use, and to have a similar opening procedure thereto.
