Abstract
Abstract The invention relates to the combination of a closure and of a container, the closure displaying a peripheral depending skirt while the container displays, along the walls thereof, a continuous peripheral flange receiving, on the top face thereof, the lower edge of the closure skirt. The connection of the flange at each corner is weakened by the presence of a series of gaps to render the flange at those areas breakable to thereby provide a visual indication of removal of the closure, whether it be authorized or unauthorized.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
125 words
In combination, a closure and a container; said closure having a top wall and a peripheral depending skirt having a lower edge; said container consisting of a body having a bottom wall and more than one flat side wall joined with rounded corners; said side walls and corners displaying a continuous peripheral flange including a horizontal portion projecting outwardly from said walls and corners; said horizontal portion receiving, in close relationship thereover, said lower edge of said skirt of said closure; said flange being integrally connected to said walls and corners; gap means in the connection of said flange at each said corner to weaken and render breakable the corner connections to thereby provide visual indication of removal of said closure, whether authorized or unauthorized.
Claim 2
Dependent Claim
125 words
In combination, a closure and a container; said closure having a top wall and a peripheral depending skirt having a lower edge; said container consisting of a body having a bottom wall and more than one flat side wall joined with rounded corners; said side walls and corners displaying a continuous peripheral flange including a horizontal portion projecting outwardly from said walls and corners; said horizontal portion receiving, in close relationship thereover, said lower edge of said skirt of said closure; said flange being integrally connected to said walls and corners; gap means in the connection of said flange at each said corner to weaken and render breakable the corner connections to thereby provide visual indication of removal of said closure, whether authorized or unauthorized.
Claim 3
Dependent Claim
49 words
A combination as defined in claim 1, further comprising gap means in the connection of said horizontal portion of said flange at said corners with contiguous horizontal portions of said flange at said side walls to thereby weaken the connection between the corner and side wall horizontal flange portions.
Claim 4
Dependent Claim
28 words
A combination as defined in claim 1 or claim 2, wherein all said connections have a reduced cross section compared with the cross section of said horizontal portions.
Claim 5
Dependent Claim

A combination as defined in claim 1, wherein said skirt of said closure displays an inverted U-shaped configuration adapted to engage upper edges of said side walls and said corners.
Claim 6
Dependent Claim
40 words
A combination as defined in claim 1, wherein said horizontal portion displays an upper lip at its outmost end thereof; said lower edge of said skirt being received rearwardly of said lip to thereby hinder access to said lower edge.
Claim 7
Dependent Claim
20 words
A combination as defined in claim 1, wherein said container is a unitary body made of injection molded plastic material.
