Abstract
Abstract A hermetically sealed, nonrotatable closure for a bottle having a cylindrical body containing liquid and having an integral tubular neck formed with a free open end, comprises an annular flange on the tubular neck. A flexible stopper mounts on the flange. A cup shaped cap has a flat top wall with peripherally integral pliable skirt in which is an internal beveled ridge. The ridge engages the flange to lock the cap on the neck of the bottle. The top wall of the cap has a central hole to expose the stopper which can be pierced by a hypodermic needle to extract the liquid from the bottle while the cap remains unbroken on the neck of the bottle. Inside the skirt of the cap are circumferentially spaced teeth which engage in circumferential slots in the annular flange to cooperate with the ridge in preventing axial movement on the cap and stopper on the bottle. Radial webs separate the slots in the annular flange and engage in stalls defined by flat radial walls of the spaced teeth to prevent the cap and stopper from rotating on the tubular neck of the bottle.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
238 words
A hermetically sealed closure for a bottle having a cylindrical body containing a liquid and having an integral tubular neck formed with a free open end, and an annular flange having a flat top surrounding and integral with said open end of said neck, said flange having a cylindrical side wall, said closure comprising: a flexible flat stopper on said flange; a cup shaped cap on said stopper and flange, said cap having a flat circular top wall peripherally integral with a pliable cylindrical skirt, said skirt having an outside diameter larger than said flange and an open bottom end section with an inside diameter slightly less than that of said cylindrical side wall of said flange, and having an internal beveled annular ridge extending from said bottom end section and tapering inwardly from said open bottom end section toward said top wall of said cap; and mutually engaging means on said skirt of said cap and said side wall of said flange for preventing rotation of said cap; whereby said cap locks on said stopper and said flange with said ridge engaged under said flange when said (neck) flange is inserted into said open end of said skirt and said cap is forced down on said flange and said mutually engaged means on said cap and said flange cooperate with said ridge to prevent said cap and stopper from respective rotation and axial movement on said bottle.
Claim 2
Dependent Claim
238 words
A hermetically sealed closure for a bottle having a cylindrical body containing a liquid and having an integral tubular neck formed with a free open end, and an annular flange having a flat top surrounding and integral with said open end of said neck, said flange having a cylindrical side wall, said closure comprising: a flexible flat stopper on said flange; a cup shaped cap on said stopper and flange, said cap having a flat circular top wall peripherally integral with a pliable cylindrical skirt, said skirt having an outside diameter larger than said flange and an open bottom end section with an inside diameter slightly less than that of said cylindrical side wall of said flange, and having an internal beveled annular ridge extending from said bottom end section and tapering inwardly from said open bottom end section toward said top wall of said cap; and mutually engaging means on said skirt of said cap and said side wall of said flange for preventing rotation of said cap; whereby said cap locks on said stopper and said flange with said ridge engaged under said flange when said (neck) flange is inserted into said open end of said skirt and said cap is forced down on said flange and said mutually engaged means on said cap and said flange cooperate with said ridge to prevent said cap and stopper from respective rotation and axial movement on said bottle.
Claim 3
Dependent Claim
78 words
A hermetically sealed closure as claimed in claim 1 wherein said mutually engaging means comprises a circumferential array of teeth inside said skirt of said cap, and a plurality of circumferential slots in said cylindrical side wall of said flange, said slots receiving a plurality of said teeth when said cap is forced down on said flange to lock said cap and stopper in place in cooperation with said ridge when said ridge is engaged under said flange.
Claim 4
Dependent Claim
92 words
A hermetically sealed closure as claimed in claim 2, wherein said teeth are formed with radial walls juxtaposed between each pair of said teeth and further comprising other means on said cap and said flange preventing rotation of said cap and said stopper on said neck of said bottle, said other means comprising radial webs spacing apart said circumferential slots in said cylindrical side wall of said flange, said spaced radial walls on said teeth defining stalls which receive said webs to prevent said cap and stopper from rotating on said bottle.
Claim 5
Dependent Claim
32 words
A closure as claimed in claim 3, wherein said stopper has a flat plate abutting said top of said flange and covering said open end of said bottle to seal the same.
Claim 6
Dependent Claim
30 words
A closure as claimed in claim 4, wherein said stopper has a central plug with said flat plate whereby said plug is inserted into said bottle to seal the same.
Claim 7
Dependent Claim
59 words
A closure as claimed in claim 4, wherein said stopper has a central plug integral with said plate and inserted into said neck to seal the same, whereby a hypodermic needle must be inserted through said hole, said plate, and said plug to extract said liquid from said bottle while said cap remains in unbroken condition on said bottle.
Claim 8
Dependent Claim
56 words
A closure as claimed in claim 5, wherein said top wall of said cap has a central hole exposing said plate, so that a hypodermic needle can be inserted through said hole and said stopper, axially of said neck to extract said liquid from said bottle while said cap remains in unbroken condition on said bottle.
Claim 9
Dependent Claim
161 words
A closure for a bottle having an integral tubular neck with an open end and an annular flange having a cylindrical side wall and a flat top surrounding and integral with said open end of said neck, comprising: a cup shaped cap on said annular flange, said cap having a flat circular top wall peripherally integral with a pliable cylindrical skirt and an open bottom end, said cap having an internal beveled annular ridge extending from said bottom end section and tapering inwardly toward said top wall of said cap, so that said cap can lock on said flange with said ridge engaging under said flange when said flange is inserted into said open end of said skirt and said cap is forced down on said flange; and mutually engageable means on said skirt of said cap and said side wall of said flange cooperating with said ridge to prevent said cap from respective rotational and axial movement on said bottle.
Claim 10
Dependent Claim
161 words
A closure for a bottle having an integral tubular neck with an open end and an annular flange having a cylindrical side wall and a flat top surrounding and integral with said open end of said neck, comprising: a cup shaped cap on said annular flange, said cap having a flat circular top wall peripherally integral with a pliable cylindrical skirt and an open bottom end, said cap having an internal beveled annular ridge extending from said bottom end section and tapering inwardly toward said top wall of said cap, so that said cap can lock on said flange with said ridge engaging under said flange when said flange is inserted into said open end of said skirt and said cap is forced down on said flange; and mutually engageable means on said skirt of said cap and said side wall of said flange cooperating with said ridge to prevent said cap from respective rotational and axial movement on said bottle.
Claim 11
Dependent Claim
