Abstract
Abstract A lid for a pilfer evident container has an inverted U-section rim in which nests an inverted U-section lip of a container, the lid rim having at least one opening in the outer limb, the outer limb of the container lip and lid rim being continuous around the lid, with the former having an outwardly projecting portion which is received by the lid opening to prevent removal of the lid after application to the container, the lid being removable by rupturing the connection between that part of the lid outer limb in the path of which, in the direction of lid removal, lies the outwardly projecting portion of the container rim.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
122 words
A lid having an inverted U-section rim in which nests an inverted U-section lip of a container, the lid rim having at least one opening in the outer limb, characterised in that the outer limb of the container lip and lid rim are continuous around the lid, the outer limb of the container lip has an outwardly projecting portion which is received by the lid opening to prevent removal of the lid after application to the container and includes means to rupture the connection between the part of the lid outer limb in the path of which, in the direction of lid removal, lies the outwardly projecting portion of the container rim to thereby permit removal of the lid from the container.
Claim 2
Dependent Claim
122 words
A lid having an inverted U-section rim in which nests an inverted U-section lip of a container, the lid rim having at least one opening in the outer limb, characterised in that the outer limb of the container lip and lid rim are continuous around the lid, the outer limb of the container lip has an outwardly projecting portion which is received by the lid opening to prevent removal of the lid after application to the container and includes means to rupture the connection between the part of the lid outer limb in the path of which, in the direction of lid removal, lies the outwardly projecting portion of the container rim to thereby permit removal of the lid from the container.
