Definitions
- the present invention relates to a screw cap comprising, concentrically with the skirt of the cap, a guarantee ring which is connected in places to this skirt by means of small spacer elements which, due to their small section, can be broken when unscrewing the cap.
- Screw caps provided with a guarantee ring of the species are known.
- the guarantee ring which is connected to the skirt of the cap by the aforementioned small elements, of low resistance, are intended to be broken when the cap is unscrewed, and this in particular because of the fact that inside the ring of guarantee are provided with hooking means designed so that the stopper and its guarantee ring can be screwed on without damage but, when unscrewing, the guarantee ring is retained by suitable means provided on the neck of the container so that that unscrewing the cap automatically causes the small spacer elements to break.
- the object of the invention is to remedy this drawback and to produce a plug of the type described in the preamble, the guarantee ring of which can never be accidentally detached during mechanical or other manipulations prior to screwing the cap onto the neck of a container.
- the aforementioned small spacer elements 5 extend obliquely between the skirt 2 of the plug and the aforementioned guarantee ring 3.
- an optional detail of the invention resides in the fact that the skirt 2 of the plug has at least one tooth 6 which penetrates into a cutout 7 of the aforementioned guarantee ring 3, the play on either side of the tooth between the walls of the cutout and the adjacent edges of the tooth being such that traction can only be exerted on the small spacer elements 5 when the plug is unscrewed.
- the single plate shows, in a view half in elevation, and half in section, a plug according to the invention.
- the screw cap according to this figure comprises, in a manner known per se, a skirt 2 and a guarantee ring 3.
- the guarantee ring 3 internally provided with small oblique teeth, passes, according to the principle of a ratchet, over small retaining members provided for the interior on the outer surface of the container neck.
- the guarantee ring passes, according to the principle of a ratchet, over small retaining members provided for the interior on the outer surface of the container neck.
- the simplest embodiment is obviously to provide the protective support elements 4 on the guarantee ring 3.
- the protective support elements 4 projecting outwards on the guarantee ring 3 protrude therefrom in the direction of the skirt 2 and prohibit any movement of relative approximation of the skirt 2 of the plug 1 compared to warranty ring 3.
- At least one tooth, 6, forming part of the skirt 2 of the plug extends in the direction of the guarantee ring and penetrates into a cutout 7 made in the latter.
- the tooth 6 and the cutout 7 have the same trapezoidal profile, the side of the trapezium being directed in the direction of unscrewing the plug.
- the clearance that remains at 8 between tooth 6 and the adjacent wall of cutout 7 is greater than the clearance that remains at 9 between this tooth and the adjacent wall of cutout 7.
