Abstract
Abstract A container 1 is provided with a lid 2 which is releasably secured to it by means of interlocking beads 4 and 8 respectively on the container and a depending skirt of the lid. An annular flange 3 which abuts and is flush with the skirt of the lid serves as a protecting member to make it difficult for the lid to be removed without making use of a tamper-evident facility provided on the upper surface of the lid. This facility consists of a pull ring 6 integrally moulded with the lid and firmly attached to it adjacent the periphery of the lid. In its inactive position, prior to the first removal of the lid from the container, it is held by a number of frangible connection points 7 in a recess 5 provided in the lid. In order to remove the lid from the container, it is necessary to grip the pull ring 6 and pull it upwards thereby breaking the connection points and providing a subsequent indication that the lid has been removed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
106 words
A lid for a container (1), the lid being a one piece structure and having a recess (5) on the upper surface thereof and an integral release element (6) secured in an inactive or stowed position in the recess (5) by frangible means (7) which will break on moving the release element (6) out of the recess (5) to an active position in which it can be used to pull the lid from the container (1) without tearing the upper surface of the lid, in the stowed condition the periphery of the release element (6) being surrounded by an inner peripheral wall of the recess (5).
Claim 2
Dependent Claim
106 words
A lid for a container (1), the lid being a one piece structure and having a recess (5) on the upper surface thereof and an integral release element (6) secured in an inactive or stowed position in the recess (5) by frangible means (7) which will break on moving the release element (6) out of the recess (5) to an active position in which it can be used to pull the lid from the container (1) without tearing the upper surface of the lid, in the stowed condition the periphery of the release element (6) being surrounded by an inner peripheral wall of the recess (5).
Claim 3
Dependent Claim
40 words
A lid according to claim 1 wherein the release element (6) is anchored to the remainder of the lid adjacent the periphery of the lid so as to remain firmly attached thereto after the frangible means (7) has been broken.

Dependent Claim
24 words
A lid according to claim 2 wherein the release element (6) is anchored effectively at a single point on the periphery of the lid.
Claim 5
Dependent Claim
47 words
A lid according to any one of the preceding claims wherein the frangible means (7) comprises a number of individual connection points of the release element (6) to the upper surface of the lid, the connection points being disposed along the length of the release element (6).
Claim 6
Dependent Claim
54 words
A lid according to any one of the preceding claims wherein the release element (6) is of generally a shape corresponding to that of the recess (5), as viewed from above and when in the inactive or stowed position, the release element (6) is below the plane of the upper surface of the lid.
Claim 7
Dependent Claim
37 words
A lid according to any one of the preceding claims wherein the release element (6) is in the form of a band or strip forming a closed loop or ring or in the form of a tab.
Claim 8
Dependent Claim
