Definitions

  • the present invention relates to a pilferproof closure.
  • closures of many containers are meant to be opened and closed more than once, since the product contained in said containers is not used all at once: this is the case, for example, of bottles which contain liquid products for household use, such as detergents or soaps.
  • closures meant to be opened only once in order to completely empty the container to which they are applied.
  • the aim of the present invention is to provide an improved pilferproof closure which is producible in a simple manner, for example by means of plastic molding in a single part, and which clearly indicates that an initial opening has occurred.
  • a pilferproof closure which comprises a body which is suitable to be associated in a non-removable manner with a container and a cap which is hinged on said body and is provided with an occlusion element, characterized in that said cap comprises at least one portion which is not efficient as regards tightness, which is connected to the cap by means of a weak link, and which is provided with means for engaging said body, so that it separates from the cap when first opening occurs.
  • closure is produced by molding plastic material, it is advantageously characterized by the presence of two opposite peripheral portions which are connected to the central portion of the cap, which comprises the occlusion element, by means of bridges, and which are provided with a tooth for engaging a complementarily shaped recess provided on ridges which extend from the body.
  • the reference numeral 1 designates a body which is suitable to be associated, in a non-removable manner, by virtue of known means, with a container such as for example a plastic bottle for containing any liquid product for household use.
  • a cap 3 is hinged at 2 to said body 1 and is provided with a grip tab 3a and with an occlusion element 3b which is suitable to be associated, in order to ensure tightness of the closure in closed position, with a hole 1a provided in the central region 1b of the body 1.
  • the cap 3 comprises two opposite peripheral portions 4 and 5 which are connected to the central portion, which comprises the occlusion element 3b, by means of a weak link defined by bridges such as 4a for the portion 4 and such as 5a or 5b for the portion 5; said portions 4 and 5 are provided with means for engaging the body 1 which are constituted by a tooth 6 for the portion 4 and by a tooth 7 for the portion 5 and are respectively shaped complementarily with respect to a recess 8 provided on the ridge 8a of the body 1 and with respect to a recess 9 defined on the ridge 9a.
  • the cross-sectional shape of the teeth 6 and 7 is triangular, in order to allow the spontaneous fall of the portions 4 and 5 under their own weight when the coupling bridges are broken, as will become apparent in the description of operation, and also to facilitate the first closure operation.
  • the co-planar arrangement of the upper surfaces of the portions 4 and 5 and of the central portion 16 of the cap 3 has a hardly negligible role in the satisfactory outcome of the operation, which is naturally performed on a filling and closure-fitting line by means of an automatic device.
  • the user grips the tab 3a of the cap 3 in order to rotate it about the hinge 2; in this step, the effect of engaging the portions 4 and 5 with the body 1, produced by the teeth 6 and 7 inserted in the recesses 8 and 9, prevails over the strength of the bridges which connect said portions to the central region of the cap, and this causes the breakage of said bridges.
  • the two portions 4 and 5 may have the most appropriate extension and may also be replaced by a single portion; the teeth 6 and 7 may furthermore have a shape which differs from the illustrated triangular one, for example a trapezoidal one, provided that, preferably, it is such as to allow the fall of the portions 4 and 5 after the breakage of the connecting bridges.
