Definitions

  • the present invention relates to a jar closure device.
  • jar closure devices comprise a lid articulated to the rim of the jar by a metal wire ring forming a hinge for the jar on one side and having, on the side diametrically opposite to the hinge, a coupling for a toggle lever that by acting on the lid locks it to the rim of the jar.
  • Jars are also known (German Utility Model no. 7631199) wherein the lid and the corresponding support are made monolithically of plastic material and the articulation of the lid to the support is constituted by a flexible hinge.
  • a principal aim of the present invention is therefore to provide a jar closure device that does not have the above mentioned drawbacks of currently commercially available ones.
  • a jar closure device characterized in that it comprises: a ring that can be coupled, in a snap-together manner, to the rim of the jar; a lid articulated to said ring and having, in an opposite position to the articulation point, a recess; a tab, which is articulated to said ring in a diametrically opposite position to the one where said lid is articulated, can be turned over onto said lid, and is provided with means for snap-together engagement in said recess and for retaining said lid in the jar closing position.
  • the reference numeral 1 designates a conventional cylindrical jar made of seamed metal plate according to conventional methods, having a rim 2 folded inwards which forms its mouth.
  • the closure shown separately in figures 2 and 3 and generally designated by the reference numeral 3, is meant to be associated with the jar 1.
  • Said closure is composed of a ring 4, a lid 5, and a tab 6, and is formed monolithically by molding plastics.
  • the ring 4 comprises a conical annular portion 6a outside which a groove 7 and an annular portion 8 are arranged.
  • the conical portion 6a has such a diameter that it can be inserted, by forcing, in the mouth of the jar 1 and provide a snap-together coupling with said jar as a consequence of the engagement of the rim 2 in the groove 7.
  • Two protrusions 9 and 10 extend in diametrically opposite directions from the ring 4; the tab 6 and the lid 5 are articulated to said protrusions by means of flexible hinges 11 and 12 made of the same plastic material that composes the closure 3.
  • the lid 5 comprises a slightly cambered disk 13 that is surrounded, along its peripheral region, by an annular expansion 14 where a groove 15 is provided having the same diameter as the annular portion 8.
  • the lid 5 is connected to the hinge 12 by a protrusion 17 extending from the expansion 14 by such a length that, when the lid is turned over onto the ring 4, the portion 8 can engage the groove 15.
  • a recess 18 is formed in the disk 13, in a diametrically opposite position to the protrusion 17, and has two parallel walls 19 wherein respective opposite hollows 20 are formed. Said hollows 20 are blind, that is to say, they do not pass through the walls 19.
  • a depressed region 21 is furthermore formed in the peripheral portion of the disk 5 at the recess 18, and its height and width are substantially equal to those of the tab 6; said depressed region forms an abutment 22 outside the expansion 14.
  • the tab 6 is connected to the protrusion 9 by an extension 23 forming a step 24 with one end of the tab.
  • the tab 6 is completed by two parallel wings 26 extending from the inner face and having, at their ends, respective pins 27 directed outwardly and having appropriately rounded ends.
  • the lid 5 When one wishes to close the jar 1, the lid 5 is turned over onto the ring 4, so that the annular portion 8 engages in the groove 15. Then the tab is turned over onto the lid, inserting the wings 26 in the recess 18. The abutment of the pins 27 against the walls 19 initially causes the wings 26 to move elastically closer to each other; when the pins 27 are at the hollows 20, this mutual approach determines the snap-together engagement of the pins in the hollows and accordingly the retention of the lid in closed position. In this position, the tab 6 is recessed in the depressed region 21 and is flush with the cambered surface of the disk 13.
  • the step 24 acts on the abutment 22 so as to force the lowering of the lid 5 onto the portion 8, accordingly increasing tightness between said lid and the gasket 16.
  • a substantial feature of the described closure is the fact that said closure can be formed monolithically by molding plastic material. This leads to considerable savings in terms of construction and assembly.
  • hinges 11 and 12 can optionally be provided by conventional pivots driven through bushes formed in the protrusions 9, 10, 17, and 24.
  • Another embodiment provides, in addition to the wings 26 and the pins 27, or as a replacement thereof, a single wing 29 (see figure 2) rigidly coupled to the tab 6, which lies on a plane that is parallel to the axis of the hinge 11, and has a sort of hook 30 that is adapted to engage a corresponding saw-tooth portion 31 of the wall 32 of the recess 18 that joins the walls 19.
