Abstract
Abstract A stoppering device non-removably attached to the flanged neck of a container has a base (8) projecting beyond the neck of the container, with at least two arcuate surface sections extending from the base and disposed along a circle having a diameter slightly greater than that of the outer surface of the flanged neck (5). Each arcuate surface section (16) is extended on at least one of its sides in the circumferential direction by a locking foot (17). Each foot is integral with the arcuate surface at the end of the section opposite to the base (8) and is inclined inward from the end integral with the arcuate surface section (16) to a free end of the foot located toward the base (8). Each foot abuts the flanged neck (5) and holds the stoppering device securely onto the container.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
120 words
A stoppering device for non-removable attachment to the neck of a container having a peripheral flange, comprising: a base having an opening of passage of products contained in the container; at least two arcuate sections projecting from said base and generally disposed in a circle, each said arcuate section having an end; and at least two resilient locking feet, each having a free end and each being integrally coupled to a side of one of said arcuate sections in a circumferential direction at said end and inclined inward from said arcuate section to said free end toward said base, said base being adapted to fit over the neck and said ends being adapted to abut the flange of the neck.
Claim 2
Dependent Claim
120 words
A stoppering device for non-removable attachment to the neck of a container having a peripheral flange, comprising: a base having an opening of passage of products contained in the container; at least two arcuate sections projecting from said base and generally disposed in a circle, each said arcuate section having an end; and at least two resilient locking feet, each having a free end and each being integrally coupled to a side of one of said arcuate sections in a circumferential direction at said end and inclined inward from said arcuate section to said free end toward said base, said base being adapted to fit over the neck and said ends being adapted to abut the flange of the neck.
