Definitions

  • the present invention relates to improvements made to overcapping capsules, more particularly although not exclusively of the kind described in French patent application FR-A-2 342 214 in the name of the present applicant and which includes a skirt of very thin.
  • Such a capsule is described in document FR-A-2108 783. Also described in prior document FR-A-2 313 278 is a conventional shutter of normal thickness, the inner face of the guarantee strip having short ribs. at a single thinning line.
  • the problem of stiffening the guarantee strip does not arise due to its thickness which does not allow any buckling, in addition the short ribs cannot play a reinforcing role.
  • the problem of buckling does not arise from the fact that the strip is joined only by one edge to the shutter.
  • the inner face of the tear-off strip of a thin-skirted overcap capsule is made up of spaced vertical ribs whose thickness suddenly decreases and becomes zero at its edges which are delimited by the lines d 'thinning of the skirt.
  • an overcap capsule assigned the general reference 1, and which is intended to be placed on the neck of a bottle in order to close it, to constitute an element of guarantee of its content, and / or to decorate it.
  • the capsule shown is that which is the subject of French patent application FR-A-2 342 214 but the invention can naturally be applied to any capsule with a tearable strip.
  • the capsule 1 shown in fig. 1 comprises a tubular body or skirt 2 closed at one of its ends by a bottom 3 whose connection with the skirt is provided with lights 4 intended for the evacuation of air during the positioning of the capsule.
  • a retaining ring 5 is provided inside the skirt 2 to allow the capsule 1 and the aforementioned neck to be joined together by snap-fastening the ring under the ring of this neck.
  • a tear-away guarantee strip 6 has been made in the skirt.
  • the strip 6 is connected to the skirt by two peripheral grooves made in the thickness of the skirt from the inside and which determine two thinning lines 7, 8. These grooves have a triangular shape in cross section if although in fact the guarantee strip is connected to the skirt only by two very thinned edges integral one 6a of the strip 6, the other 2a of the skirt 2.
  • vertical ribs 9 are spaced apart from each other on the inside of the tearable strip, the thickness of which is intended to increase the moment of inertia of the section of the strip 6 so as to avoid its deformation during the force-fitting of the capsule by axial action on its bottom 3.
  • the thickness of the ribs 9 is determined as a function of that of the strip and of the force to be applied to the bottom 3 of the capsule so that its skirt comes to surround the neck 10 of a bottle (fig. 3).
  • the thickness of each rib suddenly decreases and becomes zero at each edge 2a, 6a.
  • a cut-out or a cut 11 is made in the capsule once molded -by means of a shaped tool of gouge which cuts right through the strip 6 (fig. 1).
  • This gouge is preferably arranged obliquely relative to the periphery of said strip, that is to say that it is oriented in a non-normal manner at this periphery.
  • the user introduces the nail or an instrument into the cutout 11 so as to spread the end 6b of this strip which in fact constitutes a gripping tab.
  • the adhesion of the fingers with this tab is improved, which facilitates tearing.
