Abstract

Abstract A composite tip-off type cap, and closure sealing means, operatively connected to a container for closure thereof and sealing of the contents therein. The composite cap includes a narrow elongated exterior top portion, a peripherally enlarged open bottom skirt at the bottom thereof, and a container access opening closure seal means, operatively disposed within the skirt and operatively integrated therewith. The integrated composite cap and closure seal means 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 effected without breakage of the material forming the container. The cap and closure seal means act as a unit assembly when being removed. The construction is designed to generally assimilate known glass ampules, in configuration, use, and to have a similar opening procedure.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 166 words
A composite tip-off type cap operatively adapted for connection to a container having an access opening for closure thereof and sealing contents therein, said composite cap comprising an elongated, narrow exterior top portion, and a bottom, open-ended skirt operatively integrated therewith, said skirt having a lower edge removably attachable to a said container about a said access opening, said composite cap being conjointly removable as an integrated unit from a container, to open the container for access to the liquid therein, by application of a lateral tilting force against the elongated cap exterior at a position thereof remote from connection of the cap to the container, said elongated exterior portion being plastic and having a bottom disc thereon, said skirt being separate from said plastic portion, said skirt including a top portion having an opening therethrough, said plastic exterior portion extending through said opening, said disc being integratedly attached to an interior surface of said skirt top portion to integrate the composite cap parts during assembly.
Claim 2
Dependent Claim 166 words
A composite tip-off type cap operatively adapted for connection to a container having an access opening for closure thereof and sealing contents therein, said composite cap comprising an elongated, narrow exterior top portion, and a bottom, open-ended skirt operatively integrated therewith, said skirt having a lower edge removably attachable to a said container about a said access opening, said composite cap being conjointly removable as an integrated unit from a container, to open the container for access to the liquid therein, by application of a lateral tilting force against the elongated cap exterior at a position thereof remote from connection of the cap to the container, said elongated exterior portion being plastic and having a bottom disc thereon, said skirt being separate from said plastic portion, said skirt including a top portion having an opening therethrough, said plastic exterior portion extending through said opening, said disc being integratedly attached to an interior surface of said skirt top portion to integrate the composite cap parts during assembly.
Claim 3
Dependent Claim 12 words
A cap as claimed in claim 1, said disc being adhesively integrated.
Claim 4
Dependent Claim 39 words
A composite tip-off type cap as claimed in claim 1, the lower edge of said skirt having a plurality of peripherally spaced scores therein for lowering a required said lateral tilting force to separate said cap from said container.
Claim 5
Dependent Claim 36 words
A composite tip-off type cap as claimed in claim 1, further including an interrupted circumferential score-line in said skirt and constituting a break line to give an indication of attempted pilferage or possible container content contamination.
Claim 6
Dependent Claim 21 words
A composite tip-off type cap as claimed in claim 1, said plastic elongated portion having a multiplicity of external ribs thereon.
Claim 7
Dependent Claim 52 words
A composite tip-off type cap as claimed in claim 1, further including a snap lip recess between said elongated plastic cap portion and the upper surface of said top portion of said skirt, said recess being coactable with the periphery of said skirt top opening for interengagement of the composite cap portions.
Claim 8
Dependent Claim 62 words
A composite tip-off type cap as claimed in claim 1, the exterior of said plastic elongated portion being plain surfaced, further including a snap lip recess between said elongated plastic cap portion and the upper surface of said top portion of said skirt, said recess being coactable with the periphery of said skirt top opening for interengagement of the composite cap portions.
Claim 9
Dependent Claim 17 words
A composite tip-off type cap as claimed in claim 1, wherein said elongated plastic portion is hollow.
