Claim 6
Dependent Claim
57 words
The device of claim 1 when a rim is formed at the juncture of the end wall and side wall of the container wherein the means for compressing the pad below the first end of the plate comprises a clip attached to the plate and adapted to engage the rim in a position which compresses the pad.
Claim 7
Dependent Claim
21 words
The device of claim 5 including a tab on the clip for engaging it with and releasing it from the rim.
Claim 8
Dependent Claim
82 words
The device of claim 1 wherein the means for compressing the pad below the first end of the plate comprises a shaft extending outwardly from a position below the plate and adapted to longitudinally bear against the end wall of the container from below between the first end of the opening and the juncture of the end wall and side wall when the device is in position on the end wall of the container, and means attaching the shaft to the plate.
Claim 9
Dependent Claim
73 words
The device of claim 7 when, in forming the opening in the end wall of the container, a portion of the end wall is bent inwardly of the container adjacent the side wall of the container and the portion has a further opening therein, wherein the shaft is adapted to pass through such further opening and bear against the end wall of the container by means of the sides of such further opening.
