Abstract
Abstract A can end assembly formed from interconnected elements of a cover portion, a tear-shaped seal member and a pull member. This assembly encloses an end of a container, such as a beverage can. The cover portion has a dispensing opening and vent and a pivotable connection to one end of the seal member. The other end of the seal member is pivotably connected to the pull member. In a first position, the seal member will close the opening and will be beneath the pull member. Upon a slight lifting of the pull member, a seal between the seal member and opening will be broken. Continued movement of the pull member causes the seal member to rotate 180 degrees about its connection to the cover portion. During this movement, the pull member also rotates 180 degrees about its longitudinal axis and is displaced about 90 degrees relative to its initial orientation. This movement results in the seal member being positioned above the pull member and in these two elements being in an open, out of the way location to permit a consumer to empty the container. This movement may be reversed to temporarily reseal the container. In the open position, the seal and pull members may be temporarily locked beneath a flange partially surrounding the cover portion. A score line is provided beneath the cover portion to accommodate compression forces. A groove extends around the periphery of the cover portion to permit the can end assembly to snap onto the can body.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
189 words
A can end assembly for attachment to a can body comprising: a cover portion for covering an end of the can body, said cover portion having a first opening therein, seal means for closing said first opening, said seal means being operatively connected to said cover portion adjacent the first opening by first hinge means; a pull member having first and second distal ends and two side portions, one of said two side portions having a notch therein, second hinge means connecting said pull member to the seal means, said pull member and said seal means being movable about said first and second hinge means between a first position wherein said seal means closes the first opening and a second position wherein the first opening is substantially unobstructed by said seal means; and said pull member overlaying said seal means when in the first position, said seal means overlaying the pull member and said first hinge means folding into said notch in the second position, the longitudinal axis of said pull member being displaced approximately 90 degrees as said pull member moves from the first to the second position.
Claim 2
Dependent Claim
189 words
A can end assembly for attachment to a can body comprising: a cover portion for covering an end of the can body, said cover portion having a first opening therein, seal means for closing said first opening, said seal means being operatively connected to said cover portion adjacent the first opening by first hinge means; a pull member having first and second distal ends and two side portions, one of said two side portions having a notch therein, second hinge means connecting said pull member to the seal means, said pull member and said seal means being movable about said first and second hinge means between a first position wherein said seal means closes the first opening and a second position wherein the first opening is substantially unobstructed by said seal means; and said pull member overlaying said seal means when in the first position, said seal means overlaying the pull member and said first hinge means folding into said notch in the second position, the longitudinal axis of said pull member being displaced approximately 90 degrees as said pull member moves from the first to the second position.
Claim 3
Dependent Claim
62 words
The can end assembly as recited in claim 1 and further comprising: at least one flanged portion on said cover portion, said flanged portion engaging at least one of the first and second distal ends of the pull member when the pull member is in the second position and for temporarily locking the pull member and seal means in said second position.
Claim 4
Dependent Claim
37 words
The can end assembly as recited in claim 2, wherein said at least one flanged portion engages both the first and second distal ends of the pull member when the pull member is in the second position.
Claim 5
Dependent Claim
40 words
The can end assembly as recited in claim 1, wherein said seal means and pull member are both movable from the second position back to the first position in order for the seal means to partially reseal the first opening.
Claim 6
Dependent Claim
42 words
The can end assembly as recited in claim 1 and further comprising: a second opening provided in said cover portion, said second opening permitting venting of the can when the pull means initially begins moving from the first to the second position.
Claim 7
Dependent Claim
54 words
The can end assembly as recited in claim 1 and further comprising: a groove extending around the periphery of the cover portion for engaging an inwardly disposed flange of said can body, said groove being disposed so as to permit said can end assembly to snap onto and be retained by said can body.
Claim 8
Dependent Claim
70 words
The can end assembly as recited in claim 6 and further comprising: a bottom and top side being provided for said cover portion; and a score line extending around the bottom of said cover portion, said score line extending upwardly and outwardly into the cover portion to form a gap therein, and said score line permitting the can end assembly to withstand a compression force applied to said cover portion.
Claim 9
Dependent Claim
73 words
The can end assembly of claim 1 wherein said can end is circular and said seal means is tear-shaped with a minor edge extending substantially diametrically of said can end, said first hinge means being connected to said minor edge, said tear-shaped seal means also having a major edge extending substantially tangentially to the periphery of said circular can end and contiguous thereto, said second hinge means being connected to said major edge.
Claim 10
Dependent Claim
20 words
The can end assembly of claim 8 wherein said first and second hinge means are formed from flexible sheet material.
