Definitions

  • the present invention relates to a screw cap comprising essentially two elements formed by a skirt and a guarantee ring which is spaced from the skirt in the axial direction of the cap and 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.
  • the stopper described by this Luxembourg patent has a structure such that the displacements, along the geometrical axis of the stopper, of the skirt relative to the guarantee ring do not cause a premature, therefore untimely separation of these two elements of the stopper.
  • the plugs of this type therefore constitute a remarkable improvement from this point of view.
  • Screw caps having the same drawbacks as the plug of the aforementioned Luxembourg patent are described in the publications GB-A-2 099 800 and US-A-4 147 268.
  • the skirt of these plugs has on its outside side a protective ring which hides the small spacer elements between the skirt and the warranty ring. This protective ring cannot prevent the breaking of one or more of the small spacer elements, if a lateral force is applied to the guarantee ring.
  • the object of the present invention is to remedy the aforementioned very serious drawback which causes too many caps to be put out of use and requires, in any event, checks which should be carried out. to avoid.
  • the screw cap according to the invention is characterized in that the the aforementioned skirt has internally at least one extension which extends sufficiently far towards and beyond the edge of the aforementioned guarantee ring directed towards the aforementioned skirt and which is received radially inside the internal surface of the ring guarantee above to prevent any deformation, in the radial direction of the cap, of the aforementioned guarantee ring, deformations which could cause the aforementioned small spacer elements to break.
  • the extensions extend parallel to the geometric axis of the stopper, the guarantee ring is in alignment with the skirt in the axial direction of the stopper and the guarantee ring has the same outside diameter as the skirt.
  • a single perimeter extension or several extensions may be provided.
  • the figure is a view for half in section and for half in elevation of the plug according to the invention in one embodiment.
  • the screw cap 1 shown in the figure comprises a skirt 2, and a guarantee ring 3.
  • the guarantee ring 3 is in alignment with the skirt 2 in the axial direction of the cap 1, leaving an axial space between the skirt 2 and the warranty ring 3.
  • Protective support elements 4 can be provided on the skirt or on the guarantee ring which prevent the skirt 2 from completely approaching the guarantee ring 3 which could break some of the small spacer elements 5 which connect the ring skirt warranty.
  • the present invention aims at improvements to these plugs but also to other types of plugs, provided that they comprise a skirt, a guarantee ring spaced axially from the skirt and small spacers connecting these elements between- them.
  • means are provided according to the present invention which prevent any radial displacement of the guarantee ring 3, i.e. any movement in or out of the cap.
  • the skirt 2 has internally an extension 8 directed towards the guarantee ring 3 and received radially inside the internal surface of the guarantee ring 3.
  • the extension 8 of the skirt 2 of the plug extends far enough that any radial deformation of the guarantee ring is prevented. It suffices for this that the extension 8 extends a tenth of a millimeter or a few tenths of a millimeter beyond the edge of the guarantee ring 3 which is directed towards the skirt 2.
