Definitions

  • the present invention relates to a security closure for containers, in particular for oil cans.
  • closures known from the prior art are provided with a pouring spout which protrudes from the can cover for a considerable length and causes drawbacks during the step of can formation.
  • such closures cause difficulties in the automatic feed of the covers during their application to the cylindrical side wall of the cans.
  • the presence of such a protruding pouring spout renders unstable the can during the step of filling of said can from its bottom side, and causes difficulties when the formed and/or filled cans are stacked -- and renders unstable the can stacks.
  • Closures of improved type consisting of two components which, however, although operate in a very satisfactory way, suffer from moulding and assembling problems. Furthermore, precisely since they are constituted by two pieces, said closures are rather complex and anyway protrude from at least the lower side of the container cover.
  • US-A-3 204 829 discloses a security closure for containers according to the preamble of claim 1 comprising one single component having a collar portion from which a pouring spout portion extends.
  • the collar portion has a bottom wall through which two through holes, i.e., a pouring hole and an air-inlet hole, are provided.
  • a thread-like appendix bearing a cap element suitable for entering the collar portion above the bottom wall is furthermore connected with an external wall of an intermediate shell portion.
  • the purpose of the instant invention is to provide a security closure for containers, which overcomes the above mentioned problems.
  • Another purpose is to provide a container closure which cannot be removed from the opening provided through the cover of the can, without such a tampering being clearly set forth.
  • Such purposes are achieved according to the present invention by providing a security closure for containers, in particular for oil cans, according to claim 1.
  • a further advantage of the present invention is that it provides a simplified, single-component security closure with a structure which allows it to be contained within the upward dimension of the cover, i.e., within the thickness of the cover in the longitudinal direction of the container.
  • a cover of a metal container partially shown and indicated by the numeral 11, e.g., for an oil can, is provided with a perimetrical raised egde 12 and with a through opening 13 in its central portion. Said through opening 13 is slightly shifted towards the interior of the cover, to lay at an intermediate level relatively to the height of the perimetrical raised edge 12, such as to define a contoured edge 10.
  • a security closure of plastic material according to the present invention is positioned on said opening 13 by spring-like engagement.
  • the security closure is an enbloc structure made by moulding and its height is at maximum equal to, or smaller than, the thickness of said can cover 11.
  • Said closure essentially comprises a collar portion, generally indicated with the reference numeral 14, which can be spring-like applied and fastened inside said opening 13, and a pouring spout portion, generally indicated with the reference numeral 15.
  • the collar portion 14 has a bottom wall 16 oriented towards the interior of said container/can cover, or at a lower level than as shown in Figures 1 and 3.
  • Said bottom wall 16 is provided with a lower annular lip 17 acting as the spring-like constraint element of the closure, destined to come into engagement with the edge of the opening 13 provided through the cover of the metal container 11.
  • the lower lip 17 radially protrudes outwards.
  • the bottom wall 16 is provided with two through holes 18 and 19.
  • the first hole is the pouring hole and the second one is the air inlet hole. They can be both closed by portions of tear-away material 20 and 21, united by a tearing-away ribbon-like element 22.
  • the pouring spout 15 extends from the security closure according to the present invention.
  • a thread-like appendix 25 is constrained.
  • a moulded cap element 26 is borne by the free end of said thread-like appendix 25. Said cap element and be inserted and engaged inside said collar portion 14 of the security closure, above the bottom wall 16.
  • the cap element 26 is furthermore provided with a radially protruding, essentially "L"-shaped tab 27 suitable to come to rest on the external surface of said security closure and to cooperate to position said cap element inside the collar portion 14, as better shown in Figure 3.
  • the above-said cap element 26 is kept integral with the pouring spout 15 by a small tooth 28 provided with a rupture region 29.
  • the pouring spout portion 15 is constrained to the remainder portion of the security closure by a rupture region indicated with the reference numeral 30. If the pouring spout portion is grasped to remove the closure from the container cover, said rupture region 30 gets broken causing said pouring spout portion to be separated from the previously disclosed collar portion 14.
  • the intermediate shell portion 24 is provided with weakening and/or rupture lines, i.e., radial lines 36 and circumferential stretches 37 which display -- through their being ruptured -- that a tampering was attempted or carried out by acting on the intermediate shell portion 24 ( Figure 5).
  • the pouring spout portion 15 extends from the upper edge 23 of the intermediate shell portion 24 and is inclined and tapered towards the upper face 9 of the container cover 11. More precisely, said pouring spout portion 15 shows two side regions 31 inclined towards a central region 32. All these regions are bounded between side boundary walls 33 ( Figure 4).
  • a lid element generally indicated by the reference numeral 34 can be furthermore provided to act as a guarantee seal.
  • Said lid element is placed, with possibility of free removal, above the collar portion 14 and the pouring spout portion 15 after that the security closure is applied onto the cover of the container 11.
  • Said guarantee seal 34 can be given the structure of, e.g., a heat-welded aluminum element, or any similar materials capable of performing the same task can be used.
  • a security closure according to the present invention is easily moulded as one single piece of plastic material, and is then positioned and spring-like fastened onto an opening provided through the wall of the cover of the container or can.
  • the further typical feature of the security closure of the present invention i e., the shape of the pouring spout portion, constituted by several, suitably shaped and inclined regions, realizes a retention of the oil inside the collar element, and therefore inside the container cover, and simultaneously facilitates the pouring of oil.
  • a further feature of the present invention is that all the portions which constitute the security closure have such a height, as to be contained within the thickness of the cover of the container, i.e , within the region bounded by the plane defined by the top end of the perimetrical edge 12 and the plane on which the lower, internal face 35 of the cover of the container 11 lays.
  • This feature makes it both possible the security closures to be correctly stacked above each other without unbalancing and the container covers equipped with security closures according to the present invention to be equally correctly stacked on each other.
  • a security closure realized by moulding and, as disclosed, having a constant thickness or height, makes it possible the covers to be perfectly stacked on each other even if said security closure extends outside the cover thickness or height, by providing a wide support plane between covers.
  • a further, not least, advantageous feature is the lower lip 17 of the collar element 14 being realized exactly lined-up to the lower, internal face 35 of the container cover 11. This peculiarity makes it possible the container to be completely emptied of its contents, e.g., oil.
