Abstract
Abstract A bottle closure having a stopper which extends into the bottle opening to seal (and/or hermetically seal) the same and a collar or cap attached to the stopper and also sonically welded to the flange of the bottle extending about the opening so as to effect a vacuum seal (or partial seal) for volatiles and perishables and also to insure the integrity of the package against tampering for all types of seals where in the weld can be easily checked by application of torque to the cap collar.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
102 words
A closure for a bottle having a neck portion terminating in an opening and a flange circumferentially extending about the opening comprising a collar with portions for engaging the upper and lower surfaces of said flange about a substantial portion of said flange part of the circumference to permit said collar to be freely rotated about said flange and a stopper pivotably attached to said collar with portions of said stopper engaging said upper surface of said flange and at least in part welded to said upper surface and having a portion for extending into said bottle opening to seal said opening.
Claim 2
Dependent Claim
102 words
A closure for a bottle having a neck portion terminating in an opening and a flange circumferentially extending about the opening comprising a collar with portions for engaging the upper and lower surfaces of said flange about a substantial portion of said flange part of the circumference to permit said collar to be freely rotated about said flange and a stopper pivotably attached to said collar with portions of said stopper engaging said upper surface of said flange and at least in part welded to said upper surface and having a portion for extending into said bottle opening to seal said opening.
Claim 3
Dependent Claim
30 words
In combination as in claim 1 wherein said Portions of said stopper engaging said upper surface of said flange are at least in part sonically welded to said upper surface.
Claim 4
Dependent Claim
13 words
In combination as in claim 1 wherein said weld is a vacuum weld.
Claim 5
Dependent Claim
13 words
In combination as in claim 1 wherein said collar and stopper are plastic.
Claim 6
Dependent Claim
25 words
In combination as in claim 1 wherein said stopper has a tab portion extending beyond said collar when said stopper portion is in said opening.
Claim 7
Dependent Claim
20 words
In combination as in claim 1 wherein said stopper has a latch portion for engaging a portion of said flange.
Claim 8
Dependent Claim
134 words
In combination: a bottle having an opening for receiving and dispensing and a flange extending circumferentially about said opening, and a closure for said opening having a collar engaging the upper and lower surfaces of said flange about a substantial part of the circumference of said flange so that said collar is freely rotatable about said flange, and a stopper pivotably attached to said collar for movement between a position sealing said opening and a position permitting dispensing from said opening, said stopper having a closing portion extending down into said opening and an extending surface about said closing portion in contact with the upper surface of said flange and at least in part welded to said flange so that the integrity of the weld can be checked by applying torque to said collar.
Claim 9
Dependent Claim
134 words
In combination: a bottle having an opening for receiving and dispensing and a flange extending circumferentially about said opening, and a closure for said opening having a collar engaging the upper and lower surfaces of said flange about a substantial part of the circumference of said flange so that said collar is freely rotatable about said flange, and a stopper pivotably attached to said collar for movement between a position sealing said opening and a position permitting dispensing from said opening, said stopper having a closing portion extending down into said opening and an extending surface about said closing portion in contact with the upper surface of said flange and at least in part welded to said flange so that the integrity of the weld can be checked by applying torque to said collar.
Claim 10
Independent Claim
144 words
A method of closing a bottle having an opening for receiving and dispensing and a flange extending circumferentially about said opening comprising: placing a collar of a collar member about said flange engaging the upper and lower surfaces of said flange about a substantial part of the circumference of said flange so that said collar is freely rotatable about said flange, placing in said opening a stopper pivotably attached to said collar for movement between a position sealing said opening and a position permitting dispensing from said opening, said stopper having a closing portion extending down into said opening and an extending surface about said closing portion in contact with the upper surface of said flange and welding at least part of said extending surface to said flange so that the integrity of the weld can be checked by applying torque to said collar.
Claim 11
Independent Claim
144 words
A method of closing a bottle having an opening for receiving and dispensing and a flange extending circumferentially about said opening comprising: placing a collar of a collar member about said flange engaging the upper and lower surfaces of said flange about a substantial part of the circumference of said flange so that said collar is freely rotatable about said flange, placing in said opening a stopper pivotably attached to said collar for movement between a position sealing said opening and a position permitting dispensing from said opening, said stopper having a closing portion extending down into said opening and an extending surface about said closing portion in contact with the upper surface of said flange and welding at least part of said extending surface to said flange so that the integrity of the weld can be checked by applying torque to said collar.
Claim 12
Dependent Claim
23 words
A method as in claim 8 further including the step of applying torque to said flange to check the integrity of the weld.
