Abstract
Abstract A guarantee band for a container closure is connected to an adjacent element of the closure by a breakable separating section having a part stronger than the remainder of the section. The guarantee band has at least two weakened regions spaced around its periphery, one of said weakened regions being weaker than the other or others and the said weaker region being located near to said stronger section part. On removing the closure from a suitable container for the first time, the guarantee band will break at the said weaker region, the breakable separating section will break except at the stronger section part and the remaining weaker region or regions will each provide an articulation causing the guarantee band to adopt a drooping configuration to give an enhanced indication of breakage of the guarantee band.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
143 words
A guarantee band for a container closure having a cap part, said guarantee band including a breakable separating section connecting said guarantee band to a closure, said breakable separating section having a part stronger than the remainder of the section, wherein the quarantee band has at least two weakened regions spaced around its periphery, one of said weakened regions being weaker than the other and the said weaker region being located near to said stronger section part, so that on removing the closure from a suitable container for the first time, the guarantee band will break at the said weaker region, the breakable separating section will break except at the stronger section part and the remaining weaker region will each provide an articulation causing the guarantee band to adopt a drooping configuration to give an enhanced indication of breakage of the guarantee band.
Claim 2
Dependent Claim
143 words
A guarantee band for a container closure having a cap part, said guarantee band including a breakable separating section connecting said guarantee band to a closure, said breakable separating section having a part stronger than the remainder of the section, wherein the quarantee band has at least two weakened regions spaced around its periphery, one of said weakened regions being weaker than the other and the said weaker region being located near to said stronger section part, so that on removing the closure from a suitable container for the first time, the guarantee band will break at the said weaker region, the breakable separating section will break except at the stronger section part and the remaining weaker region will each provide an articulation causing the guarantee band to adopt a drooping configuration to give an enhanced indication of breakage of the guarantee band.
Claim 3
Dependent Claim
79 words
A guarantee band as claimed in claim 1, wherein said weakened regions of the guarantee band are produced by forming each of said regions as a thinner connecting web between thicker sections of the guarantee band and wherein said connecting web of said one weakened region is constituted by a web which is thinner than and is shorter, measured in a direction from top to bottom of the guarantee band, than the connecting web of the other weakened region.
Claim 4
Dependent Claim
26 words
A guarantee band as claimed in claim 2, wherein only two weakened regions are present and are located at diametrically opposed positions around the guarantee band.
Claim 5
Dependent Claim
23 words
A guarantee band as claimed in claim 2, wherein said stronger section part is immediately adjacent said weaker region of the guarantee band.
Claim 6
Dependent Claim
26 words
A guarantee band as claimed in claim 1, wherein only two weakened regions are present and are located at diametrically opposed positions around the guarantee band.
Claim 7
Dependent Claim
23 words
A guarantee band as claimed in claim 5, wherein said stronger section part is immediately adjacent said weaker region of the guarantee band.
Claim 8
Dependent Claim
23 words
A guarantee band as claimed in claim 1, wherein said stronger section part is immediately adjacent said weaker region of the guarantee band.
Claim 9
Dependent Claim
21 words
A guarantee band as claimed in claim 1 and formed in one piece with the cap part of a container closure.
Claim 10
Dependent Claim
29 words
A guarantee band as claimed in claim 1 and formed with a mounting element portion defining an insert, which is attachable to the cap part of a container closure.
Claim 11
Dependent Claim
39 words
A guarantee band as claimed in claim 9, wherein the insert is made of a plastics material flexible enough to stretch without breaking over a bead of a container neck on first application of the closure to a container.
Claim 12
Dependent Claim
37 words
A guarantee band as claimed in claim 1, wherein said breakable separating section is constituted by a number of connecting bridges disposed at intervals around the guarantee band and one of which is stronger than the others.
Claim 13
Dependent Claim
155 words
A container closure including a cap part and an insert attachable to said cap part, said insert including a mounting element portion and guarantee band including a breakable separating section connecting said guarantee band to said mounting element portion, said breakable section having a part stronger than the remainder of the section, wherein the guarantee band has at least two weakened regions spaced around its periphery, one of said weakened regions being weaker than the other and the said weaker region being located near to said stronger section part, so that on removing the closure from a suitable container for the first time, the guarantee band will break at the said weaker region, the breakable separating section will break except at the stronger section part and the remaining weaker region will each provide an articulation causing the guarantee band to adopt a drooping configuration to give an enhanced indication of breakable of the guarantee band.
Claim 14
Dependent Claim
155 words
A container closure including a cap part and an insert attachable to said cap part, said insert including a mounting element portion and guarantee band including a breakable separating section connecting said guarantee band to said mounting element portion, said breakable section having a part stronger than the remainder of the section, wherein the guarantee band has at least two weakened regions spaced around its periphery, one of said weakened regions being weaker than the other and the said weaker region being located near to said stronger section part, so that on removing the closure from a suitable container for the first time, the guarantee band will break at the said weaker region, the breakable separating section will break except at the stronger section part and the remaining weaker region will each provide an articulation causing the guarantee band to adopt a drooping configuration to give an enhanced indication of breakable of the guarantee band.
Claim 15
Dependent Claim
22 words
A container closure as claimed in claim 12, wherein the insert and cap part are made of materials providing a colour contrast.
Claim 16
Dependent Claim
81 words
A container closure according to claim 12, wherein said insert is made of a plastics material flexible enough to stretch without breaking over a bead of a container neck of a first application of the container closure to a container, and in that the cap part is made of a plastics material having good pressure-resisting properties in use and a sufficiently high heat distortion temperature to permit a gasket material to be flowed in and heat treated in the cap part
