Abstract

This disclosure relates to a novelty safety closure comprising a fitment and a cap for assembly together and telescopic press application onto a container finish, the cap having means reinforcing a part of the fitment against outward deflection, the fitment having an interior surface reducing in diameter from a leading surface portion thereof toward the opposite end thereof, the leading surface portion in the area of the reinforcing means having a diameter sufficient to permit telescopic assembly of the cap and fitment on an associated container finish with little initial resistance to the relative telescopic movement of the diminishing diameter of the fitment above said surface portion with thereafter increasing resistance to a point of interference which is offset by radial outward deflection of the fitment above said surface portion, and the fitment terminates at the opposite end thereof in means for axially opposing abutment of an associated container finish thereby precluding unauthorized removal of the fitment and/or cap from a container finish. The finish also includes means for axially opposing abutment of the fitment abutment means, and in a preferred embodiment of the invention the finish and fitment abutment means are opposed annular shoulders.

Claims

1. A closure comprising a tubular fitment and a cap assembled together for subsequent telescopic press application onto a container finish, said fitment having a frusto-conical interior surface said cap having an end panel and a peripheral skirt with means reinforcing a part of said fitment against outward deflection, said tubular fitment having an interior surface reducing in diameter from a leading surface portion thereof remote from said end panel toward the opposite end thereof adjacent said end panel, said leading surface portion in the area of said reinforcing means having a diameter sufficient to permit telescopic assembly of the cap and fitment on an associated container finish with little initial resistance to the relative telescopic movement, and the diminishing diameter of said fitment above said surface portion thereafter increasing the resistance of telescopic assembly to a point of interference which if offset by radial outward deflection of said fitment above said surface portion, and said fitment terminates at said opposite end thereof in means for axially opposing abutment of an associated container finish thereby precluding unauthorized removal of said fitment and/or cap from a container finish.

2. The closure as defined in claim 1 wherein said reinforcing means additionally defines means for releasably securing said cap to said fitment.

3. The closure as defined in claim 1 wherein said reinforcing means additionally defines lug means for releasably securing said cap to said fitment.

4. The closure as defined in claim 1 including a container having a finish, and said finish also includes means for axially opposing abutment of said fitment abutment means.

5. The closure as defined in claim 1 wherein said fitment abutment means is a terminal annular face of said fitment opposite end.

6. The closure as defined in claim 4 wherein said fitment abutment means is a terminal annular face of said fitment opposite end.

7. The closure as defined in claim 4 wherein said finish abutment means is a circumferential bead.

8. The closure as defined in claim 5 wherein said finish abutment means is a circumferential bead.

9. The closure as defined in claim 8 wherein said circumferential bead has an exterior diameter greater than the interior diameter of said fitment interior surface at said fitment terminal annular face.

10. A closure comprising a tubular fitment and a cap assembled together for subsequent telescopic press application onto a container finish, said fitment having a frusto-conical interior surface said cap having an end panel and a peripheral skirt with means reinforcing a part of said fitment against outward deflection, said tubular firment having an interior surface reducing in diameter from a leading surface portion thereof remote from said end panel toward the opposite end thereof adjacent said end panel, said leading surface portion in the area of said reinforcing means having a diameter sufficient to permit telescopic assembly of the cap and fitment on an associated container finish with little initial resistance to the relative telescopic movement, and the diminishing diameter of said fitment above said surface portion thereafter increasing the resistance of telescopic assembly to a point of interference which is offset by radial outward deflection of said fitment above said surface portion, said fitment terminates at said opposite end thereof in means fOr axially opposing abutment of an associated container finish thereby precluding unauthorized removal of said fitment and/or cap from a container finish, and means for snap-securing a metallic container body to said container finish.

11. The closure as defined in claim 10 including a panel spanning the container finish and having a dispensing aperture therein.

12. The closure as defined in claim 1 in combination with a container body having a finish, said finish includes an exterior surface surrounded by said interior frusto-conical fitment surface, and a circumferential gap between said last-mentioned two surfaces extending axially substantially entirely the axial length of said interior frusto-conical fitment surface.

13. The closure as defined in claim 12 wherein said finish also includes means for axially opposing abutment of said fitment abutment means, and said finish abutment means are axially opposing spaced annular walls between which are sandwiched said fitment with each of axially opposite end faces of said fitment abutting a respective adjacent one of said annular walls.

14. A closure comprising a tubular fitment and a cap assembled together for subsequent telescopic press application onto a container finish, said fitment having a frusto-conical interior surface, said cap having an end panel and a peripheral skirt with means reinforcing a part of said fitment against outward deflection, said tubular fitment having an interior surface reducing in diameter from a leading surface portion thereof remote from said end panel toward the opposite end thereof adjacent said end panel, said leading surface portion in the area of said reinforcing means having a diameter sufficient to permit telescopic assembly of the cap in fitment on an associated container finish with little initial resistance to relative telescopic movement, and the diminishing diameter of said fitment above said surface portion thereafter increasing the resistance of telescopic assembly to a point of interference which is offset by radial outward deflection of said fitment above said surface portion.

15. The closure as defined in claim 14 in combination with a container body having a finish, said finish includes an exterior surface surrounded by said interior frusto-conical fitment surface, and a circumferential gap between said last-mentioned two surfaces extending axially substantially entirely the axial length of said interior frusto-conical fitment surface.
