Abstract

Abstract A tool for more easily removing a conventional screw-cap bottle closure from a soft drink bottle, and the like, has a resilient body member provided with a recess forming a screw-cap receiving socket. The recess has a sealing lip provided adjacent the mouth of the recess for sealingly engaging a bottle associated with the closure and preventing leakage from the closure to pass down the side of the bottle. One, or more, protuberance is advantageously formed in the recess of the body member for mating with an upper row of knurls on the closure and providing additional gripping action between the tool and the closure. The outer surface of the body member forms a torque applying surface which facilitates removal, and reapplication, of the screw-cap.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 79 words
A tool for facilitating removal of a conventional screw-cap bottle closure, comprising a body member provided with a recess forming a socket for receiving the closure, and including means for gripping the closure the recess having a mouth arranged for permitting reception of a closure in the recess said body having a sealing lip arranged immediately adjacent the mouth thereof for sealingly engaging the bottle associated with the closure and preventing leakage down an outer surface of the bottle.
Claim 2
Dependent Claim 79 words
A tool for facilitating removal of a conventional screw-cap bottle closure, comprising a body member provided with a recess forming a socket for receiving the closure, and including means for gripping the closure the recess having a mouth arranged for permitting reception of a closure in the recess said body having a sealing lip arranged immediately adjacent the mouth thereof for sealingly engaging the bottle associated with the closure and preventing leakage down an outer surface of the bottle.
Claim 3
Dependent Claim 56 words
A structure as defined in claim 1, wherein the body member is in the form of a hollow cylinder constructed from a resilient material and having a cylindrical wall and an end wall enclosing one open end formed by the cylindrical wall, the cylindrical wall providing an outer cylindrical surface arranged forming a torque applying surface.
Claim 4
Dependent Claim 84 words
A structure as defined in claim 2, wherein a ring constructed from a rigid material is disposed in the body member adjacent the mouth thereof, and the body member is provided with a relieved portion arranged in communication with the recess, the relieved portion being associated with the ring for permitting the flaring out of a pilfer-proof vertical bridge on the closure when same is removed from a bottle, and preventing a consumer from collapsing the vertical bridge once same has been so flared.
Claim 5
Dependent Claim 70 words
A structure as defined in claim 3, wherein at least one proturbance is formed on the body member and is arranged extending into the recess of the body member at a point in the recess spaced from the mouth of the recess for mating with an upper row of knurls arranged on the conventional screw-cap bottle closure and providing a positive gripping force between the body member and the closure.
Claim 6
Dependent Claim 70 words
A structure as defined in claim 1, wherein at least one proturbance is formed on the body member and is arranged extending into the recess of the body member at a point in the recess spaced from the mouth of the recess for mating with an upper row of knurls arranged on the conventional screw-cap bottle closure and providing a positive gripping force between the body member and the closure.
Claim 7
Dependent Claim 138 words
In combination with a conventional screw-cap bottle closure and an associated bottle, a tool for facilitating removal of the screw-cap, the tool comprising, a body member provided with a recess forming a socket for receiving the closure, and including means for gripping the closure the closure arranged in the socket, the recess having a mouth, a relieved portion provided on the body member adjacent the mouth thereof and arranged in communication with the recess for permiting a pilfer-proof vertical bridge provided on the closure to flare outwardly into the relieved portion, and a sealing lip provided on the body member immediately adjacent the mouth of the recess, between the mouth of the recess and the relieved portion, and arranged extending into the recess and in engagement with the bottle for sealing the body member relative to the bottle.
Claim 8
Dependent Claim 138 words
In combination with a conventional screw-cap bottle closure and an associated bottle, a tool for facilitating removal of the screw-cap, the tool comprising, a body member provided with a recess forming a socket for receiving the closure, and including means for gripping the closure the closure arranged in the socket, the recess having a mouth, a relieved portion provided on the body member adjacent the mouth thereof and arranged in communication with the recess for permiting a pilfer-proof vertical bridge provided on the closure to flare outwardly into the relieved portion, and a sealing lip provided on the body member immediately adjacent the mouth of the recess, between the mouth of the recess and the relieved portion, and arranged extending into the recess and in engagement with the bottle for sealing the body member relative to the bottle.
Claim 9
Dependent Claim 56 words
A structure as defined in claim 6, wherein the body member is in the form of a hollow cylinder constructed from a resilient material and having a cylindrical wall and an end wall enclosing one open end formed by the cylindrical wall, the cylindrical wall providing an outer cylindrical surface arranged forming a torque applying surface.
Claim 10
Dependent Claim 73 words
A structure as defined in claim 6, wherein the closure is provided with a circumferential row of knurls, and at least one proturbance is formed on the body member and arranged extending into the recess of the body member at a point in the recess spaced from the mouth of the recess for mating with the row of knurls provided on the closure for permitting the body member to positively engage the closure.
