Abstract
Abstract A closure cap formed of plastic for a container, especially a bottle or the like, comprising a cap lift-off or removal nose member which protrudes away from the outer periphery of the body of the closure cap. At least one reference rupture location is provided at a region in the neighborhood of the cap lift-off nose member, which region is stressed during pushing the closure cap off of the container, or such reference rupture location is provided at the cap lift-off nose member itself. Tearing of the reference rupture location indicates any possible unauthorized opening of the container. The regions containing the reference rupture locations form a part of the closure cap member which can be removed as a unit with the cap lift-off nose.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
144 words
A closure cap formed of plastic for use with a container, especially a flask or bottle, comprising a closure cap having a cap body, a cap lift-off nose extending away from the outer periphery of the body of the closure cap, at least one reference rupture location provided for said closure cap, said reference rupture location tearing upon removal of the closure cap from the container, the region of the closure cap containing said reference rupture location forming a part of the closure cap which can be removed as a unit together with the cap lift-off nose, said closure cap including at least one lateral connection surface extending between the cap lift-off nose and the outer periphery of the body of the closure cap, said at least one reference rupture location comprising at least one reference rupture line provided at said lateral connection surface.
Claim 2
Dependent Claim
144 words
A closure cap formed of plastic for use with a container, especially a flask or bottle, comprising a closure cap having a cap body, a cap lift-off nose extending away from the outer periphery of the body of the closure cap, at least one reference rupture location provided for said closure cap, said reference rupture location tearing upon removal of the closure cap from the container, the region of the closure cap containing said reference rupture location forming a part of the closure cap which can be removed as a unit together with the cap lift-off nose, said closure cap including at least one lateral connection surface extending between the cap lift-off nose and the outer periphery of the body of the closure cap, said at least one reference rupture location comprising at least one reference rupture line provided at said lateral connection surface.
Claim 3
Dependent Claim
146 words
A closure cap formed of plastic for use with a container, especially a flask or bottle, comprising a closure cap having a cap body, a cap lift-off nose extending away from the outer periphery of the body of the closure cap, at least one reference rupture location provided for said closure cap, said reference rupture location tearing upon removal of the closure cap from the container, the region of the closure cap containing said reference rupture location forming a part of the closure cap which can be removed as a unit together with the cap lift-off nose, said reference rupture location comprising a reference rupture line provided at the cap lift-off nose at a region thereof neighboring the periphery of the body of the closure cap, and reinforcement wall means provided for the cap lift-off nose, said reinforcing wall means laterally bounding said reference rupture line.
Claim 4
Dependent Claim
146 words
A closure cap formed of plastic for use with a container, especially a flask or bottle, comprising a closure cap having a cap body, a cap lift-off nose extending away from the outer periphery of the body of the closure cap, at least one reference rupture location provided for said closure cap, said reference rupture location tearing upon removal of the closure cap from the container, the region of the closure cap containing said reference rupture location forming a part of the closure cap which can be removed as a unit together with the cap lift-off nose, said reference rupture location comprising a reference rupture line provided at the cap lift-off nose at a region thereof neighboring the periphery of the body of the closure cap, and reinforcement wall means provided for the cap lift-off nose, said reinforcing wall means laterally bounding said reference rupture line.
Claim 5
Dependent Claim
144 words
A closure cap formed of plastic for use with a container, especially a flask or bottle, comprising a closure cap having a cap body, a cap lift-off nose extending away from the outer periphery of the body of the closure cap, at least one reference rupture location provided for said closure cap, said reference rupture location tearing upon removal of the closure cap from the container, the region of the closure cap containing said reference rupture location forming a part of the closure cap which can be removed as a unit together with the cap lift-off nose, said closure cap including at least one lateral connection strut extending between the cap lift-off nose and the outer periphery of the body of the closure cap, said at least one reference rupture location comprising at least one reference rupture location provided at said lateral connection strut.
Claim 6
Dependent Claim
