Abstract
Abstract Container with a wall that is integrated with a cap having a plug that extends sufficiently through a weakened region of the container wall to prevent inadvertent rupture of the cap during shipment and handling of the container. Because of the extension of the plug, inadvertent movement of the cap produces only a rotation of the plug into contact with a side wall of the container that limits any further rotation and prevents inadvertent breakage of the plug and consequent loss of the container contents. The container and integral cap are desirably fabricated by injection molding with plastic materials.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
112 words
A container with an integral cap, comprising a plug extending from said cap through a wall of said container, said wall having a weakened region which becomes deformed and severed when said cap is depressed towards said container, and said plug having an extension into the interior of said container which is proportioned to limit the movement of said cap during shipment and handling of said container to resist severence of said cap from said container during the occurrence of inadverent forces during handling and shipment by the contact of the extension of said plug with an interior wall of said container before a force sufficient to rupture said wall is encountered.
Claim 2
Dependent Claim
112 words
A container with an integral cap, comprising a plug extending from said cap through a wall of said container, said wall having a weakened region which becomes deformed and severed when said cap is depressed towards said container, and said plug having an extension into the interior of said container which is proportioned to limit the movement of said cap during shipment and handling of said container to resist severence of said cap from said container during the occurrence of inadverent forces during handling and shipment by the contact of the extension of said plug with an interior wall of said container before a force sufficient to rupture said wall is encountered.
Claim 3
Dependent Claim
35 words
A container in accordance with claim 1 wherein the extension of said plug is limited to a angular displacement of less than about 30 degrees during the occurrence of inadvertent forces applied to said cap.
Claim 4
Dependent Claim
24 words
A container in accordance with claim 2 wherein said displacement is ended by the occurrence of contact of the plug extension with said wall.
Claim 5
Dependent Claim
29 words
A container in accordance with claim 1 wherein said container includes a neck having an interior opening with a diameter which does not exceed the length of said extension.
Claim 6
Dependent Claim
25 words
A container in accordance with claim 1 wherein said wall and said extension form a channel which is narrower than the length of said plug.
Claim 7
Dependent Claim
30 words
A container in accordance with claim 1 wherein said plug has a conical shape with external walls which diverge away from the connection of said plug to said container wall.
Claim 8
Dependent Claim
20 words
A container in accordance with claim 1 wherein said plug contains a sealing groove between said cap and said wall.
Claim 9
Dependent Claim
19 words
A container in accordance with claim 1 wherein said weakened region includes a plurality of recesses having different widths.
Claim 10
Dependent Claim
18 words
A container in accordance with claim 1 wherein said wall is on the end portion of said container.
Claim 11
Dependent Claim
41 words
A container in accordance with claim 1 wherein said cap is formed by injection molding using a runner system in the form of a ladder to facilitate the flow of plastic during molding and provide added strength to facilitate secondary operations.
