Definitions

  • This invention proposes a capsule for the closing of bottles, in particular bottles for infusions, provided with tearing means suitable to allow the removal of the capsule and the complete separation of the parts made of different materials.
  • the capsule is configured so as to, after the use, the aluminium ring nut that keeps the closing cap in perforable rubber at its place can be removed from the bottle neck, being separated from both the rubber cap and the plastic protection lid.
  • the capsule provides the use of an aluminium ring nut, to be shut around the bottle neck in order to block the rubber cap, that presents two parallel incision lines running along the ring nut circumference and defining, with a slit appropriately shaped, a detachable tongue that allows the separation of the ring nut from the bottle.
  • One of these pre-fracture lines extends to reach the lower edge of the ring nut, so that, tearing the tongue away, this latter is opened and separated both from the bottle and from the other parts made of different materials.
  • the bottles containing products for infusion are closed in general with a rubber cap, which is fixed in its place shutting in general around the bottle neck an aluminium ring nut, that presents on the upper side an opening suitable to perforate the rubber cap in order to take the product.
  • a protection lid generally in plastic, destined to be removed when used.
  • a capsule for a bottle closed with a rubber cap including a first lid made of an aluminium rod with a hole in the centre, to be put over this rubber cap, an aluminium ring nut shaped so as to define, in the upper wall, a handle ring for the tearing off and the removal of the ring nut (which presents a pre-fracture line that connects the base of this handle ring with the lower edge of the ring nut) and a protection lid in plastic that lays on the ring nut and presents centrally a plurality of teeth protruding towards the lower part, which are inserted into the central hole of the disk that lays on the cap and are then turned outside in order to shut the disk and the aluminium ring nut against the closing lid.
  • the present invention refers to this branch and has the purpose to get round the above mentioned limitations and difficulties.
  • the invention proposes a closing capsule for bottles for infusions made of only two pieces, in particular of an aluminium ring nut and a plastic protection slid, where the aluminium ring nut presents more pre-incision lines, in particular two, suitable to define a tongue for the ring nut removal and where one of said incision lines extends to reach the lower edge of the ring nut itself.
  • figure 1 is the view of the aluminium ring nut in a capsule according to the innovaion
  • figure 2 is a section of the protection lid to be applied to the ring nut
  • figure 3 is the view of a complete capsule, assembled.
  • the capsule according to the invention includes an element, generally in aluminium, shown in the whole with 1 in figure 1, to be applied to the neck of a bottle in order to keep the closing rubber cap in its place and a protection slid, shown in the whole with 2, to be fixed to this aluminium element 1.
  • the element 1 is substantially made of a annular ring nut 3 with the upper edge 4 bent so as to define a kind of annular wall that centrally presents a hole 5.
  • the annular ring nut 3 is inserted into the bottle neck and shut bending its lower edge inside.
  • the upper annular wall 4 then, lays against the rubber cap, keeping it in its place but allowing, through the hole 5, to reach this cap in order to perforate it and take the product.
  • the wall 4 presents an annular stiffening rib 6 and has the edge 7 of the hole 5 bent so as to give to wall 4, in that area, a greater thickness.
  • this ring nut 3 presents a couple of incisions, shown respectively with 8 and 9, which form the same number of preferential breaking lines.
  • the part of the ring nut 3 included between lines 8 and 9 forms a tearing tongue 10 and in correspondence of an end of this tongue a notch 11 is provided in the wall of the ring nut 3, in order to allow the raising and the firm grasping of the end of the tongue when the capsule is taken away.
  • a series of scoring 12 or similar are provided, suitable to facilitate the grasp, and a rib 13 set with a lengthwise trend, that is it extends for a certain segment along the axis of tongue 10.
  • This rib 13 has the purpose to slightly stiffen the tongue 10 in correspondence of the area that is located near the edge of the notch 11, where the tongue is subject to the greatest stress when the tearing off begins.
  • the incision line located nearer to the lower edge of the ring nut 3, in this specific case line 9, reaching a certain point of the circumference, meets an incision line 14 that turns towards the lower part, presenting a curve segment, or a segment bent at 90°, that reaches the lower edge.
  • This incision is located at a certain distance from the end of the tongue, between 45° and 180°, and is cut in the aluminium for the whole length that goes from the pre-fraction line to the edge, while it is only incised in correspondence of the edge.
  • line 14 does not cause any problem during the closing, that normally happens by means of rollers that bend the aluminium of the edge below the ring of the bottle.
  • the protection lid 2 presents a side edge 15, the height of which, as shown with H in figure 2, is greater than the distance between the upper edge of ring nut 3 and the first of the incision lines 8.
  • the lid 2 in correspondence of the lower wall, is provided with a plurality of teeth 16, suitable to be inserted into the hole 5 of wall 4 of the closing ring nut, in order to be bent outside and be folded in this way at the edge 7 of the capsule, and to keep the lid in its place.
  • the body 1 is applied to the container, inserting it on the bottle neck and then bending inside the lower edge of the ring nut 3, that engages a corresponding annular thickening provided on the bottle.
  • the body 2 was previuosly applied to body 1 of the capsule, inserting the teeth 16 into the opening 5 and then bending them outside, so as to shut the lid against the upper wall 4 of the capsule itself.
  • the lid 2 In order to reach the inside and take the liquid, the lid 2 is torn off, freeing in this way the opening 5 that allows to reach the perforable cap below.
