Abstract
Abstract A closure is provided for use with a container of the type having a neck extending outwardly from a body member defining an opening into the container interior. The closure includes a circular cover member adapted to be positioned over the opening and means for securing the cover to the body member. At least one vent hole is provided extending through the cover. A liner adapted to be positioned between the neck and cover member is also provided. The liner comprises a generally flat disc formed of a resilient material having a bottom surface adapted to seat on top of the container neck and seal the neck opening. The top surface of the liner includes rib means coupled to the disc extending upwardly from the disc top surface. The rib means includes a plurality of radially extending ribs spaced outwardly from a segmented circular rib.

Claim 1
Independent Claim
142 words
An improved container comprising: a body member; a neck extending from said body member defining an opening into the interior thereof; a closure for said body member including a circular cover member adapted to be positioned over said neck opening, at least one vent hole extending through said cover member, and means for securing said cover member to said body member; a liner adapted to be positioned between said neck and said cover member, said liner comprising a generally flat disc formed of resilient material having a bottom surface adapted to seat on the top of said neck and effectively close said neck opening and a top surface; and rib means coupled to said disc extending upwardly from said top surface, said rib means including a plurality of ribs extending radially and a segmented circular rib spaced inwardly from said radial ribs.
Claim 2
Dependent Claim
142 words
An improved container comprising: a body member; a neck extending from said body member defining an opening into the interior thereof; a closure for said body member including a circular cover member adapted to be positioned over said neck opening, at least one vent hole extending through said cover member, and means for securing said cover member to said body member; a liner adapted to be positioned between said neck and said cover member, said liner comprising a generally flat disc formed of resilient material having a bottom surface adapted to seat on the top of said neck and effectively close said neck opening and a top surface; and rib means coupled to said disc extending upwardly from said top surface, said rib means including a plurality of ribs extending radially and a segmented circular rib spaced inwardly from said radial ribs.
Claim 3
Dependent Claim
43 words
The invention in accordance with claim 1 wherein said radial rib means comprises a plurality of identical spaced apart elongated members extending beyond the periphery of said disc from a circle spaced outwardly from said circular rib and concentric with said disc center.
Claim 4
Dependent Claim
70 words
The invention in accordance with claim 2 further comprising a closed circular rib disposed on said liner top surface wherein said segmented circular rib is spaced radially outwardly of the projection of said cover vent hole on said liner and said closed circular rib is spaced radially inwardly of said vent hole projection whereby said vent hole projection is disposed between said closed circular rib and said segmented circular rib.
Claim 5
Dependent Claim
69 words
The invention in accordance with claim 3 comprising two vent holes extending through said cover member, said vent holes being spaced substantially equidistant from the center of said cover on opposite sides of a diameter thereof wherein said segmented circular rib and said solid circular rib of said liner are aligned concentric with the center of said cover whereby said vent hole projections are disposed between said circular ribs.
Claim 6
Dependent Claim
141 words
A closure for a container of the type having a body member and a neck extending from said body member defining an opening into the interior thereof, said closure comprising a circular cover member adapted to be positioned over said opening, at least one vent hole extending through said cover member, means for securing said cover to said body member and a liner adapted to be positioned between said neCk and said cover member, said liner comprising a generally flat disc formed of resilient material having a bottom surface adapted to seat on the top of said neck and effectively close said neck opening, a top surface, and rib means coupled to said disc extending upwardly from said top surface, said rib means including a plurality of ribs extending radially and a segmented circular rib spaced inwardly from said radial ribs.
Claim 7
Dependent Claim
141 words
A closure for a container of the type having a body member and a neck extending from said body member defining an opening into the interior thereof, said closure comprising a circular cover member adapted to be positioned over said opening, at least one vent hole extending through said cover member, means for securing said cover to said body member and a liner adapted to be positioned between said neCk and said cover member, said liner comprising a generally flat disc formed of resilient material having a bottom surface adapted to seat on the top of said neck and effectively close said neck opening, a top surface, and rib means coupled to said disc extending upwardly from said top surface, said rib means including a plurality of ribs extending radially and a segmented circular rib spaced inwardly from said radial ribs.

Dependent Claim
42 words
The invention in accordance with claim 5 wherein said radial rib means comprises a plurality of identical spaced-apart elongated members extending beyond the periphery of said disc from a circle spaced outwardly from said circular rib and concentric with said disc center.
Claim 9
Dependent Claim
70 words
The invention in accordance with claim 6 further comprising a closed circular rib disposed on said liner top surface wherein said segmented circular rib is spaced radially outwardly of the projection of said cover vent hole on said liner and said closed circular rib is spaced radially inwardly of said vent hole projection whereby said vent hole projection is disposed between said closed circular rib and said segmented circular rib.
Claim 10
Dependent Claim
69 words
The invention in accordance with claim 7 comprising two vent holes extending through said cover member, said vent holes being spaced substantially equidistant from the center of said cover on opposite sides of a diameter thereof wherein said segmented circular rib and said solid circular rib of said liner are aligned concentric with the center of said cover whereby said vent hole projections are disposed between said circular ribs.
Claim 11
Dependent Claim
142 words
A liner for use with a container of the type having a body member having an outwardly extending cylindrical neck defining an opening into the interior thereof and a closure including a circular cover adapted to be positioned over said opening, at least one vent hole extending through said cover member, and means for coupling said cover member to said body member, said liner being adapted to be positioned between said neck and said cover member and comprising a generally flat disc formed of resilient material having a bottom surface adapted to seat on the top of said neck and effectively close said neck opening, a top surface, and rib means coupled to said disc extending upwardly from said top surface, said rib means including a plurality of ribs extending radially and a segmented circular rib spaced inwardly from said radial ribs.
Claim 12
Dependent Claim
142 words
A liner for use with a container of the type having a body member having an outwardly extending cylindrical neck defining an opening into the interior thereof and a closure including a circular cover adapted to be positioned over said opening, at least one vent hole extending through said cover member, and means for coupling said cover member to said body member, said liner being adapted to be positioned between said neck and said cover member and comprising a generally flat disc formed of resilient material having a bottom surface adapted to seat on the top of said neck and effectively close said neck opening, a top surface, and rib means coupled to said disc extending upwardly from said top surface, said rib means including a plurality of ribs extending radially and a segmented circular rib spaced inwardly from said radial ribs.
