Abstract
Abstract An interlocking closure device comprising two closure profiles operable for being interlocked continuously over a predetermined length features the closure profiles having different colors, whereby the position of the closure profiles on a container can be easily identified visually in order to simplify the closing and opening of the container and/or the complete occlusion of the closure profiles can be easily verified visually.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
83 words
An interlocking closure device comprising two closure profiles operable for being interlocked continuously over a predetermined length, wherein the improvement comprises each of said closure profiles being completely colored in different colors, said closure profiles being interlocking so as to visually contrast said closure profiles relative to one another when occluded without visual disappearance of either closure profile color, whereby the position of the closure profiles on a container can be easily identified visually to simplify the closing and opening of the container.
Claim 2
Dependent Claim
83 words
An interlocking closure device comprising two closure profiles operable for being interlocked continuously over a predetermined length, wherein the improvement comprises each of said closure profiles being completely colored in different colors, said closure profiles being interlocking so as to visually contrast said closure profiles relative to one another when occluded without visual disappearance of either closure profile color, whereby the position of the closure profiles on a container can be easily identified visually to simplify the closing and opening of the container.
Claim 3
Dependent Claim
26 words
The closure device as claimed in claim 1, wherein one of said closure profiles partially encircles the other closure profile when said closure profiles are occluded.
Claim 4
Dependent Claim
24 words
The closure device as claimed in claim 1, wherein at least one of said closure profiles passes sufficient light to be at least translucent.
Claim 5
Dependent Claim
18 words
The closure device as claimed in claim 1, wherein at least one of said closure profiles is opaque.
Claim 6
Dependent Claim
20 words
The closure device as claimed in claim 1, wherein at least one of said closure profiles includes a flange portion.
Claim 7
Dependent Claim
23 words
The closure device as claimed in claim 5, wherein said flange portion and the remainder of said one closure profile are different colors.
Claim 8
Dependent Claim
14 words
The closure device as claimed in claim 6, wherein said flange portion is transparent.
Claim 9
Dependent Claim
18 words
The closure device as claimed in claim 6, wherein said remainder of said one closure profile is transparent.
Claim 10
Dependent Claim
18 words
The closure device as claimed in claim 5, wherein each of said closure profiles includes a flange portion.
Claim 11
Dependent Claim
20 words
The closure device as claimed in claim 1, wherein each of said closure profiles includes a plurality of hook portions.
Claim 12
Dependent Claim
77 words
An interlocking closure device comprising two closure profiles operable for being interlocked continuously over a predetermined length, wherein each of said closure profiles is a different transparent or translucent primary color thereby producing a predetermined visible secondary color when said closure profiles are occluded, so that the position of the closure profiles on a container and the complete occlusion of the closure profiles can be easily identified visually to simplify the closing and opening of the container.
Claim 13
Dependent Claim
77 words
An interlocking closure device comprising two closure profiles operable for being interlocked continuously over a predetermined length, wherein each of said closure profiles is a different transparent or translucent primary color thereby producing a predetermined visible secondary color when said closure profiles are occluded, so that the position of the closure profiles on a container and the complete occlusion of the closure profiles can be easily identified visually to simplify the closing and opening of the container.
