Abstract
Abstract The present invention pertains to manually manipulated apparatus for and the method associated therewith of securing and retaining a plug-type container cover in position in the open top of a rimmed container. Securing apparatus is adapted to locally and progressively press the U-shaped rim of the cover into locked and seated condition on the rim of the container while providing support to the outer rim of the container.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
224 words
Apparatus for manually securing a downwardly turned U-shaped outer rim portion of a cover oNto the outwardly extending mating rim of an open top container so as to mount the cover on the container rim, the manual apparatus including: (a) a support arm including a freely turning first roller carried by said arm and selectively movable to a position where it is adapted to engage the undersurface of the outwardly extending rim of the container and in association to locally support the rim during a cover applying sequence; (b) a freely-turning second roller also carried by a support arm, this second roller supported so that its periphery engages a U-shaped rim portion of the cover and in applying position is so spaced from the first roller that a determined local seating pressure is applied to the cover rim to cause a local seating of the container rim to be achieved; (c) means for moving said rollers to achieve simultaneous relative movement of the support arm and the container and cover so that the support and the applying rollers are moved circumferentially around the container rim and cover rim to sequentially press the U-shaped rim portion of the cover in a seated condition on the rim of the container, and (d) means for removing the manual applying apparatus from the container and its mounted cover.
Claim 2
Dependent Claim
224 words
Apparatus for manually securing a downwardly turned U-shaped outer rim portion of a cover oNto the outwardly extending mating rim of an open top container so as to mount the cover on the container rim, the manual apparatus including: (a) a support arm including a freely turning first roller carried by said arm and selectively movable to a position where it is adapted to engage the undersurface of the outwardly extending rim of the container and in association to locally support the rim during a cover applying sequence; (b) a freely-turning second roller also carried by a support arm, this second roller supported so that its periphery engages a U-shaped rim portion of the cover and in applying position is so spaced from the first roller that a determined local seating pressure is applied to the cover rim to cause a local seating of the container rim to be achieved; (c) means for moving said rollers to achieve simultaneous relative movement of the support arm and the container and cover so that the support and the applying rollers are moved circumferentially around the container rim and cover rim to sequentially press the U-shaped rim portion of the cover in a seated condition on the rim of the container, and (d) means for removing the manual applying apparatus from the container and its mounted cover.
Claim 3
Dependent Claim
35 words
Apparatus for manually mounting a cover to a container as in claim 1 in which the first and second rollers are carried on the end of a common arm rotatably carried by a support member.
Claim 4
Dependent Claim
70 words
Apparatus for manually mounting a cover to a container as in claim 2 in which the support member carrying the common arm is a plate-like member configured so as to be seated in position on the central portion of the cover during and while the arm is moved to execute a circumferential traverse of the container rim and cover rim to be achieved by the spaced first and second rollers.
Claim 5
Dependent Claim
47 words
Apparatus for manually mounting of a cover to a container as in claim 3 in which one of the rollers is formed with a conical end providing a cam means for initially pressing a first local portion of the cover to a mounted condition on the container.
Claim 6
Independent Claim
220 words
The method for manually securing a downwardly turned U-shaped outer rim portion of a cover onto the outwardly extending mating rim of an open top container so as to mount said cover on the container rim, the method steps including: (a) providing a freely turning first roller carried by a support arm so that the periphery of the first rolller is adapted to engage the undersurface of the outwardly extending rim of the container to locally support the container rim during a cover applying step; (b) providing a second roller, freely-turning and also carried by a support arm, the second roller supported so that in a pressure applying attitude its periphery locally engages the U-shaped rim portion of the cover and is so spaced from the first roller that a determined local seating pressure is exerted to the cover rim to cause local seating of the container rim to be achieved; (c) providing means for simultaneous relative movement of the first and second rollers and the container cover so that the support and pressure applying rollers move circumferentially around the container rim and cover rim to sequentially press the U-shaped rim portion of the cover into seated condition on the rim of the container, and (d) providing means for removing the container with its mounted cover from the manual apparatus.
Claim 7
Independent Claim
220 words
The method for manually securing a downwardly turned U-shaped outer rim portion of a cover onto the outwardly extending mating rim of an open top container so as to mount said cover on the container rim, the method steps including: (a) providing a freely turning first roller carried by a support arm so that the periphery of the first rolller is adapted to engage the undersurface of the outwardly extending rim of the container to locally support the container rim during a cover applying step; (b) providing a second roller, freely-turning and also carried by a support arm, the second roller supported so that in a pressure applying attitude its periphery locally engages the U-shaped rim portion of the cover and is so spaced from the first roller that a determined local seating pressure is exerted to the cover rim to cause local seating of the container rim to be achieved; (c) providing means for simultaneous relative movement of the first and second rollers and the container cover so that the support and pressure applying rollers move circumferentially around the container rim and cover rim to sequentially press the U-shaped rim portion of the cover into seated condition on the rim of the container, and (d) providing means for removing the container with its mounted cover from the manual apparatus.
Claim 8
Dependent Claim
35 words
The method of manually mounting a cover onto a container as in claim 5 which includes mounting the first and second rollers on the end of a common arm rotatably carried by a support member.
Claim 9
Dependent Claim
76 words
The method of manually mounting a cover onto a container as in claim 6 which further includes carrying the first and second roller on a common arm which is rotatably mounted on a plate-like member configured so as to be seated and positioned on the central portion of the cover during and while the arm is moved to execute a circumferential traverse of the container rim and cover rim by the spaced first and second rollers.
Claim 10
Dependent Claim
47 words
The method of mAnually mounting a cover onto a container as in claim 7 which further includes forming one of the rollers with a conical end providing a cam means for initially pressing a first local portion of the cover to a mounted condition on the container.
