Abstract
Abstract A two-piece crown cap with a flexible internal member that seals the neck of a bottle and a rigid external member that covers the internal member and holds it firmly in place. The external member has lines of weakness along which it is broken to give access to the internal member when the bottle is to be opened. Interfitting formations on the cap members cooperate during assembly to ensure sound sealing and a tight fit on the bottle.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
196 words
A crown cap of plastics for a bottle having an external groove on its neck, characterized by comprising an internal member of flexible plastics adapted to be fitted on the neck of the bottle and having an outwardly projecting edge which is made readily yieldable by a plurality of radial notches, the edge being adapted to be engaged in the annular groove in the bottle neck, and a deformable central projection adapted to fit into the bottle neck to close the bottle, and an external member of rigid plastics adapted to snap on the internal member in order to cover the internal member and to prevent deformation of the annular edge of the internal member after the annular edge has been engaged in the bottle neck groove, the external member being moreover provided with an annular extension extending downwardly and adapted to engage the projection on the internal member in order to press the projection against the bottle neck and seal the bottle; the external member being formed with lines of weakness along which it can be fractured and removed from the bottle to give access to the internal member for removal of the internal member.
Claim 2
Dependent Claim
196 words
A crown cap of plastics for a bottle having an external groove on its neck, characterized by comprising an internal member of flexible plastics adapted to be fitted on the neck of the bottle and having an outwardly projecting edge which is made readily yieldable by a plurality of radial notches, the edge being adapted to be engaged in the annular groove in the bottle neck, and a deformable central projection adapted to fit into the bottle neck to close the bottle, and an external member of rigid plastics adapted to snap on the internal member in order to cover the internal member and to prevent deformation of the annular edge of the internal member after the annular edge has been engaged in the bottle neck groove, the external member being moreover provided with an annular extension extending downwardly and adapted to engage the projection on the internal member in order to press the projection against the bottle neck and seal the bottle; the external member being formed with lines of weakness along which it can be fractured and removed from the bottle to give access to the internal member for removal of the internal member.
Claim 3
Dependent Claim
55 words
A crown cap as claimed in claim 1, characterized by the fact that the internal member is provided on its flexible lower edge with an inner projection adapted to be engaged in the groove in the bottle and with an outer projection adapted to cooperate with a radially inward annular projection on the external member.
Claim 4
Dependent Claim
47 words
A crown cap as claimed in claim 1, characterized by the fact that the external member is subdivided into a number of portions held together by a removable intermediate portion adapted to be gripped by the operator to enable the external member to be fractured by hand.
Claim 5
Dependent Claim
52 words
A crown cap as claimed in claim 1, characterized by the fact that the external member is centrally provided with an axial pin extending downwardly and adapted to engage in a recess in the internal member in order to interconnect the two cap members before the cap is fitted to the bottle.
