Abstract
Abstract Disclosed is a container end with an integral opening apparatus which includes pull means for tearing a tab defined by a score line from the container end to form an opening. The score line is substantially U-shaped and the pull means is attached on the tab near the base of the U. Since the score line is U-shaped, the top of the U which defines one end of the tab is not severed from the container, thus the tab may be folded over the edge of the container end and maintained in a captured position out of the way of the user.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
227 words
A container end with integral opening means comprising: (a) a substantially flat and substantially circular disc adapted to form the end of a container; (b) a weakening score with spaced apart ends formed in said disc defining a partially removeable elongated tab having a first end and a second end and extending across the face of said disc with the first end of said tab positioned relatively near one edge of said disc and the second end of said tab positioned substantially diametrically disposed from said first end and between the geometric center of said disc and the opposite edge, the space between said spaced apart ends of said score defining said second end; (c) pull means comprising an elongated body with a substantially flat edge portion extending therefrom; and (d) attachment means securing said substantially flat edge portion of said pull means to said elongated tab near said first end thereof permitting said substantially flat edge portion of said pull means to rotate about said attachment means in a plane substantially parallel with the plane of said substantially circular disc; whereby said pull means may be rotated to a position between said attachment means and the edge of said disc nearest said first end of said tab to draw said first end outwardly from said container to a position adjacent the opposite edge of said disc.
Claim 2
Dependent Claim
227 words
A container end with integral opening means comprising: (a) a substantially flat and substantially circular disc adapted to form the end of a container; (b) a weakening score with spaced apart ends formed in said disc defining a partially removeable elongated tab having a first end and a second end and extending across the face of said disc with the first end of said tab positioned relatively near one edge of said disc and the second end of said tab positioned substantially diametrically disposed from said first end and between the geometric center of said disc and the opposite edge, the space between said spaced apart ends of said score defining said second end; (c) pull means comprising an elongated body with a substantially flat edge portion extending therefrom; and (d) attachment means securing said substantially flat edge portion of said pull means to said elongated tab near said first end thereof permitting said substantially flat edge portion of said pull means to rotate about said attachment means in a plane substantially parallel with the plane of said substantially circular disc; whereby said pull means may be rotated to a position between said attachment means and the edge of said disc nearest said first end of said tab to draw said first end outwardly from said container to a position adjacent the opposite edge of said disc.
Claim 3
Dependent Claim
21 words
A container end as defined in claim 1 wherein said first end of said tab is wider than said second end.
Claim 4
Dependent Claim
26 words
A container end as defined in claim 1 wherein said weakening score defines a relatively narrow tab section at the extreme first end of said tab.
Claim 5
Dependent Claim
26 words
A container end as defined in claim 3 wherein said relatively narrow tab section is a narrow curved extension of said first end of said tab.
Claim 6
Dependent Claim
15 words
A container end as defined in claim 1 wherein said elongated body is a ring.
Claim 7
Dependent Claim
47 words
A container end as defined in claim 1 wherein said pull means is pivotal outwardly from said disc by bending said substantially flat edge portion to a position wherein the major portion of said pull means is disposed in a plane substantially 90° from said edge portion.
Claim 8
Dependent Claim
42 words
A container end as defined in claim 1 including means for securing said pull means to the edge of said disc opposite said first end of said tab after the first end of said tab has been severed from said container end.
Claim 9
Dependent Claim
72 words
A container end as defined in claim 6 including at least one boss member extending from said pull means, said boss member pivotal with said pull means and having an end extending outwardly therefrom when said pull means is positioned parallel with said substantially circular disc and extending substantially parallel with said substantially circular disc when said pull means is pivoted outwardly to a position approximately 90° from said substantially circular disc.
Claim 10
Dependent Claim
33 words
A container end as defined in claim 8 wherein said at least one boss member comprises two boss members, one positioned on each side of said edge portion rotatably secured to said tab.
Claim 11
Dependent Claim
31 words
A container end as defined in claim 1 wherein said portion of said tab adjacent said first end thereof is substantially wider than the portion thereof adjacent said second end thereof.
Claim 12
Dependent Claim
27 words
A container end as defined in claim 1 wherein said weakening score defines an elongated tab with a substantially elongated relatively narrow portion adjacent said second end.
