Abstract
Abstract In a safety cap of the kind consisting of a base out of soft material intended to be mounted on the mouth of a bottle, and a closure intended to be screwed on the base, there is a sealing ring (5 and 12) at the bottom of both the closure and the base. The sealing rings (5 and 12) are designed in such a way that they are not removable after fracture of the closures. Thus, the user will be completely sure that the contents of the bottle are those expected, as it is easy for the user to ascertain whether the bottle was opened.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
188 words
A two part security cap of plastic or like material adapted to be mounted on a mouth of a container and constructed to provide indication of unauthorized opening, the two part security cap including a base subassembly to be mounted on the mouth of the container and a closure subassembly for mounting on the base subassembly respectively comprising a base collar member and a closure cap member each having a security ring at the bottom thereof connected to the associated base collar member and closure cap member by thin frangible bridges, the security ring of the closure subassembly and the base collar member of the base subassembly having interengaging formations restraining the same against relative movement whereby the frangible bridges interconnecting said security ring with its associated closure cap member are caused to fracture when the closure subassembly is removed from the base subassembly, and the security ring of the base subassembly having means securing the same against rotation on the mouth of the container whereby forced removal of the base subassembly from the container produced fracture of the frangible bridges associated with the last mentioned security ring.
Claim 2
Dependent Claim
188 words
A two part security cap of plastic or like material adapted to be mounted on a mouth of a container and constructed to provide indication of unauthorized opening, the two part security cap including a base subassembly to be mounted on the mouth of the container and a closure subassembly for mounting on the base subassembly respectively comprising a base collar member and a closure cap member each having a security ring at the bottom thereof connected to the associated base collar member and closure cap member by thin frangible bridges, the security ring of the closure subassembly and the base collar member of the base subassembly having interengaging formations restraining the same against relative movement whereby the frangible bridges interconnecting said security ring with its associated closure cap member are caused to fracture when the closure subassembly is removed from the base subassembly, and the security ring of the base subassembly having means securing the same against rotation on the mouth of the container whereby forced removal of the base subassembly from the container produced fracture of the frangible bridges associated with the last mentioned security ring.
Claim 3
Dependent Claim
35 words
A safety cap as defined in claim 1, wherein said base collar member and said closure cap member include complementary screw threads coactive with each other for threading the closure subassembly onto the base subassembly.
Claim 4
Dependent Claim
75 words
A safety cap as defined in claim 2, wherein the means interconnecting the security ring of said closure subassembly to the base collar member of said base subassembly include sawtooth shoulder formations on said security ring interengaging barb-like tooth formations on said base collar member and means in restraining engagement with each other for preventing relative rotation of the closure subassembly on the base subassembly in a direction to decouple such subassemblies from each other.
Claim 5
Dependent Claim
59 words
A safety cap as defined in claim 2, wherein said container includes a protruding bulge formation, and said security ring of the base subassembly having a plurality of inwardly directed barb formations to engage the container bulge formation upon assembly on the container and secure said last mentioned security ring against relative rotation on or removal from the container.
Claim 6
Dependent Claim
75 words
A safety cap as defined in claim 1, wherein the means interconnecting the security ring of said closure subassembly to the base collar member of said base subassembly include saw-tooth shoulder formations on said security ring interengaging barb-like tooth formations on said base collar member and means in restraining engagement with each other for preventing relative rotation of the closure subassembly on the base subassembly in a direction to decouple such subassemblies from each other.
Claim 7
Dependent Claim
59 words
A safety cap as defined in claim 5, wherein said container includes a protruding bulge formation, and said security ring of the base subassembly having a plurality of inwardly directed barb formations to engage the container bulge formation upon assembly on the container and secure said last mentioned security ring against relative rotation on or removal from the container.
Claim 8
Dependent Claim
59 words
A safety cap as defined in claim 1, wherein said container includes a protruding bulge formation, and said security ring of the base subassembly having a plurality of inwardly directed barb formations to engage the container bulge formation upon assembly on the container and secure said last mentioned security ring against relative rotation on or removal from the container.
