Abstract
Abstract A safety closure for bottles with a thread on the neck and a bead arranged thereunder, including a screw cap and a safety ring fastened thereon with safety fracture stays. At least two teeth are arranged offset relative to one another by a circumferential angle on the neck of the bottle on the bead. At least two break-open pins which are offset relative one another by a circumferential angle are joined on the lower edge of the screw cap. The safety ring is provided with at least one safety breaking point.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
152 words
A safety closure and bottle combination, said bottle having a thread on the neck and a bead arranged thereunder, including a screw cap adapted to be screwed on the thread on the neck of said bottle, a safety ring disposed around said screw cap, safety fracture stays breakably connecting said safety ring with said screw cap, at least two teeth arranged offset relative to one another by a circumferential angle on the bead, at least two break-open pins offset relative to one another by a circumferential angle, joined on a lower edge of said screw cap and adapted to operatively cooperate with said at least two teeth, said safety ring being formed with at least one safety breaking area, whereby upon screwing off said screw cap, said at least two break-open pins cooperate respectively with said at least two teeth and cause said safety ring to break at said safety breaking area.
Claim 2
Dependent Claim
152 words
A safety closure and bottle combination, said bottle having a thread on the neck and a bead arranged thereunder, including a screw cap adapted to be screwed on the thread on the neck of said bottle, a safety ring disposed around said screw cap, safety fracture stays breakably connecting said safety ring with said screw cap, at least two teeth arranged offset relative to one another by a circumferential angle on the bead, at least two break-open pins offset relative to one another by a circumferential angle, joined on a lower edge of said screw cap and adapted to operatively cooperate with said at least two teeth, said safety ring being formed with at least one safety breaking area, whereby upon screwing off said screw cap, said at least two break-open pins cooperate respectively with said at least two teeth and cause said safety ring to break at said safety breaking area.
Claim 3
Dependent Claim
44 words
The safety closure and bottle combination, as set forth in claim 1, wherein said at least two teeth each includes a back sloping upwardly from an upper side of the bead in a closing direction of said screw cap with respect to the bottle.
Claim 4
Dependent Claim
39 words
The safety closure and bottle combination, as set forth in claim 2, wherein said back of each of said at least two teeth is additionally inclined tapering from outwardly toward an inner direction to the neck of the bottle.
Claim 5
Dependent Claim
43 words
The safety closure and bottle combination, as set forth in claim 1, wherein said at least two teeth each includes a front extending outwardly substantially tangentially from the neck of the bottle in an opening direction of said screw cap from the neck.
Claim 6
Dependent Claim
42 words
The safety closure and bottle combination, as set forth in claim 1, wherein said at least two teeth each includes a front extending outwardly at an obtuse angle in an opening direction of said screw cap from the neck of the bottle.
Claim 7
Dependent Claim
56 words
The safety closure and bottle combination, as set forth in claim 5, wherein each of said at least two teeth includes a back facing in a direction opposite to a closing direction of said screw cap, said front of each of said at least two teeth additionally is inclined from a base thereof to said back.
Claim 8
Dependent Claim
28 words
The safety closure and bottle combination, as set forth in claim 1, wherein said at least two teeth each includes a head terminating outwardly flush with the bead.
Claim 9
Dependent Claim
50 words
The safety closure and bottle combination, as set forth in claim 1, wherein said at least two break-open pins are made of an elastically flexible material and lie in the longitudinal direction of the neck of the bottle with a loose condition of said screw cap set on the bottle.
Claim 10
Dependent Claim
30 words
The safety closure and bottle combination, as set forth in claim 1, wherein said at least two break-open pins are formed thinner than the radial width of the bead of
Claim 11
Dependent Claim
53 words
The safety closure and bottle combination, as set forth in claim 1, wherein said at least two teeth each have a back facing opposite a direction of closing of said screw cap, said at least two break-open pins are formed thinner than said backs of said at least two teeth are wide, respectively.
Claim 12
Dependent Claim
71 words
The safety closure and bottle combination, as set forth in claim 1, wherein said at least two teeth constitute a plurality of teeth greater than two spaced circumferentially around the bead of the bottle with spaces between said teeth, a plurality greater than two of said at least two break-open pins, in a closed screwed-on position of the screw cap on the bottle, lies in said spaces between said teeth, respectively.
Claim 13
Dependent Claim
61 words
The safety closure and bottle combination, as set forth in claim 11, wherein said teeth each have a front, said break-open pins have lower ends, respectively, said lower ends of said break-open pins point to said fronts of said teeth, respectively, said fronts lying adjacent in an opening direction relative thereto, respectively, in the screwed on position of the screw cap.
Claim 14
Dependent Claim
32 words
The safety closure and bottle combination, as set forth in claim 11, wherein the number of said teeth and said break-open pins as well as the circumferential angle therebetween are equal, respectively.
Claim 15
Dependent Claim
41 words
The safety closure and bottle combination, as set forth in claim 1, wherein said safety breaking area of said safety ring lies between two of said safety fracture stays and extends in a longitudinal direction of the neck of the bottle.
Claim 16
Dependent Claim
34 words
The safety closure and bottle combination, as set forth in claim 1, wherein said screw cap with said at least two break-open pins and said safety ring is made of a thermoplastic synthetic material.
