Definitions

  • the present invention relates to a pilverproof cap for a can closure.
  • caps to be applied to spray-cans and the like which have a so-called safety seal, i.e. a lower collar which is connected to the remaining part of the cap by means of a weakening line which facilitates the tearing off of said collar, are already currently commercially available.
  • a tab or another easily accessible element which is specifically preset so that it is possible, simply with one's hand, without excessive effort, to tear the collar off to indicate that the cap has been opened.
  • caps in which, in order to perform the first opening, it is necessary to use tools, such as levers, screwdrivers and the like, i.e. caps which cannot be simply opened manually.
  • Caps of said type are known from EP-A-0 207 832, for example.
  • cap which, inside the outer skirt, has a coaxial cylindrical body which mates at the region where the dispenser valve of the can is seamed.
  • An opening is defined on the outer skirt and allows the insertion of a tip of a screwdriver in order to perform a lever action which allows to uncouple the central body from the seaming collar of the valve body.
  • the aim of the invention is indeed to solve the above described problem in providing a pilverproof cap for a can which allows to provide a firm coupling, with the need to use an opening tool, at the time of first opening, using said tool in a region which is distant from the dispenser valve.
  • the cap to the invention comprises a substantially cylindrical body or outer skirt 1 which is closed at the base by a bottom.
  • An edge band 10 is provided at the edge opposite to said base or bottom and has, inside it, a tooth 11 which advantageously extends in circumferential segments; in the described example, which must not be understood in a limiting sense, two semi-circumferential segments are provided in practice.
  • the tooth 11 is particularly raised and normally protrudes, with respect to the inner surface of the band, by an amount comprised between 0.8 and 1.2 mm.
  • the tooth 11 is defined by a guiding face 11a and by an abutment face 11b which in practice engages below the collar 15 of a can.
  • the engagement is such that it is not possible to manually disengage the cap while the edge band is completely unbroken.
  • the edge band has at least one tab, indicated by 21, which is provided in the region not affected by the tooth 11.
  • two opposite tabs 21 are advantageously provided and are surmounted by a recess or opening 22 of the outer skirt so as to create a small slot.
  • the tab is laterally delimited, in the direction of extension of the edge band, by two fracture lines 23 which have a reduced thickness, generally comprised between 0.4 and 0.6 mm, and do not allow tear-off breakage of the tab simply by acting with one's hand, since the thickness of the fracture line is relatively high.
  • the breakage of the tab allows to interrupt the continuity of the edge face, so that by performing a radial compression at the tab it is possible to generate an "ovalization" of the outer skirt 2 which allows to perform, with a certain effort, the disengagement of the tooth from the collar.
  • the invention achieves the proposed aim and objects, and in particular the fact is stressed that by means of an extremely simple structure one obtains a fully pilferproof cap, i.e. a cap executed so as to prevent manual opening as long as the edge band is completely unbroken, since the forcing of the application, which is also facilitated by the pre-heating of the cap prior to its application, creates a very strong coupling of the tooth 11 below the collar 20.
  • a safety cap is available which, in order to be opened, requires the execution of a radial compression at the region affected by the removed tab, so as to allow an ovalization of the skirt and thus facilitate the disengagement of the tooth from the collar.
  • the materials employed may be any according to the requirements.
