Abstract
Abstract A closure cap is disclosed herein having a double latch closure system for controlling the rotation of the cap on a container and which includes an angular displaceable indicating marker for signifying unauthorized container opening. In one form, the cap includes a first container closure portion having upright, spaced apart driven segments and a second cover portion rotatably mounted on the first portion having downwardly depending driving segments interposed between selected ones of the driven segments so that clockwise or counterclockwise rotation of the cover portion translates into rotation of the closure portion via engagement of the driving segments with the driven segments. A pair of markers carried on the exterior of the closure and cover portion cooperate to indicate displacement of the cover portion from its initial or original position.

Independent Claim
90 words
A closure assembly for a container comprising: a closure cap having a first position relative to the container signifying an initially unopened position and a second position relative to the container signifying an opened or pre-tampered position; angular displacement indicating marker means cooperatively carried on said closure cap and said container designating said closure cap in either one of said first or second positions; and said marker means includes reference indicia displayed on said container and on said closure cap whereby angular displacement separates said respective indicia in spaced-apart relationship.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
73 words
The invention as defined in claim 1 wherein: said closure cap having at least one latch closure system having a closure portion detachably disposed on said container and a cover portion movably carried on said closure portion; and interference means cooperatively disposed between said closure portion and said cover portion adapted to forcibly engage and yeldably respond when said cover portion is moved on said closure portion beyond limits of said interference means.
Claim 4
Dependent Claim
