Abstract

Abstract This specification discloses a can, preferably for liquid, such as beverage, comprising preferably a corrugated cylindrical body, a disc-like bottom that is attached to the body after the can is filled, and inner and outer disc-like tops. The inner top is scored along two spaced arcuate lines over a sector of about 90* with the arcuate lines being connected at one end by a curved end scored line. This end of the scored area is formed with an aperture and the remainder of the scored area is scored along spaced transverse or radial lines. The outer top has a peripheral flange that is bent over a bead on the end of the circular body. It is scored along two curved lines which converge away from a rounded end with this end portion being formed with an aperture in alignment with the aperture in the inner top. A headed pin passes through these aligned apertures and is soldered to the inner top. When a can is to be opened the outer top is first rotated in a counter-clockwise direction which causes the scored area of the inner top to crumple or collapse along the radial scored lines. The outer top is then rotated in a clockwise direction which causes the scored area thereof to be pulled down into the opening left by the crumpling of the scored area of the inner top which action is caused by the scored area of the outer top breaking away from the remainder thereof beginning with the rounded end.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 145 words
In a can a. a cylindrical body presenting upper and lower ends, b. an inner top affixed to said upper end and having a scored area defined by a pair of spaced arcuate lines and an end line that are weakened, and a plurality of spaced radial lines in said scored area that are weakened, c. an outer top rotatably mounted on said body above said inner top and having a scored area defined by a pair of spaced curved lines that extend in substantially the same direction as the arcuate lines on the inner top and an end line that are weakened, d. means for securing together the scored area portion at substantially the end line of the inner top with the scored area portion at substantially the end line of the outer top e. a bottom closing the lower end of said body.
Claim 2
Dependent Claim 145 words
In a can a. a cylindrical body presenting upper and lower ends, b. an inner top affixed to said upper end and having a scored area defined by a pair of spaced arcuate lines and an end line that are weakened, and a plurality of spaced radial lines in said scored area that are weakened, c. an outer top rotatably mounted on said body above said inner top and having a scored area defined by a pair of spaced curved lines that extend in substantially the same direction as the arcuate lines on the inner top and an end line that are weakened, d. means for securing together the scored area portion at substantially the end line of the inner top with the scored area portion at substantially the end line of the outer top e. a bottom closing the lower end of said body.
Claim 3
Dependent Claim 17 words
