Abstract
Jar closure device, comprising: a ring (4) that can be coupled, in a snap-together manner, to the rim of the jar (1); a lid (5) articulated to the ring (4) and having, in an opposite position to the articulation point, a recess (18); a tab (6), which is articulated to the ring (4) in a diametrically opposite position to the one where the lid is articulated and which can be turned over onto the lid (5), the tab (6) being provided with means (26,27) for snap-together engagement in the recess (18) and for retaining the lid in the position for closing the jar.
Description
- The present invention relates to a jar closure device.
- It is known that current 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.
- Conventional closure devices, however, have been found to be complicated to produce and troublesome to apply.
- 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.
- This aim is achieved with 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.
- Further characteristics and advantages of the invention will become apparent from the following detailed description of a preferred embodiment thereof illustrated only by way of non-limitative example in the accompanying drawings, wherein:
- figure 1 is a partially sectional view of a jar with the closure device according to the present invention;
- figure 2 is a sectional view of the closure device, with the lid in open condition; and
- figure 3 is a perspective view of the closure device.
- With reference to the above figures, 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, alid 5, and atab 6, and is formed monolithically by molding plastics. Thering 4 comprises a conical annular portion 6a outside which agroove 7 and anannular 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 thegroove 7. - Two
protrusions ring 4; thetab 6 and thelid 5 are articulated to said protrusions by means offlexible hinges 11 and 12 made of the same plastic material that composes the closure 3. - The
lid 5 comprises a slightly cambereddisk 13 that is surrounded, along its peripheral region, by anannular expansion 14 where agroove 15 is provided having the same diameter as theannular portion 8. A sealinggasket 16, made of a rubber-like material, is accommodated in thegroove 15. - The
lid 5 is connected to thehinge 12 by aprotrusion 17 extending from theexpansion 14 by such a length that, when the lid is turned over onto thering 4, theportion 8 can engage thegroove 15. - A
recess 18 is formed in thedisk 13, in a diametrically opposite position to theprotrusion 17, and has twoparallel walls 19 wherein respectiveopposite hollows 20 are formed. Saidhollows 20 are blind, that is to say, they do not pass through thewalls 19. - A
depressed region 21 is furthermore formed in the peripheral portion of thedisk 5 at therecess 18, and its height and width are substantially equal to those of thetab 6; said depressed region forms anabutment 22 outside theexpansion 14. - The
tab 6 is connected to theprotrusion 9 by anextension 23 forming astep 24 with one end of the tab. - All the
protrusions extension 23 are provided with stiffening ribs designated by thereference numeral 25 only as regards those provided on theextension 23. - The
tab 6 is completed by twoparallel wings 26 extending from the inner face and having, at their ends,respective pins 27 directed outwardly and having appropriately rounded ends. - The method of operating with the closure according to the invention can be easily deduced from the above description.
- When one wishes to close the jar 1, the
lid 5 is turned over onto thering 4, so that theannular portion 8 engages in thegroove 15. Then the tab is turned over onto the lid, inserting thewings 26 in therecess 18. The abutment of thepins 27 against thewalls 19 initially causes thewings 26 to move elastically closer to each other; when thepins 27 are at thehollows 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, thetab 6 is recessed in thedepressed region 21 and is flush with the cambered surface of thedisk 13. - It should be noted that during the last part of the stroke for inserting the
wings 26 in therecess 18, thestep 24 acts on theabutment 22 so as to force the lowering of thelid 5 onto theportion 8, accordingly increasing tightness between said lid and thegasket 16. - As shown more clearly by figure 1, when the lid is in closed position the
tab 6 does not close therecess 18 completely but leaves open anopening 28 which allows the user to insert a finger therein to raise the tab and release the lid. - 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.
- Numerous modifications and variations are possible in the practical embodiment of the invention, and all are within the scope of the inventive concept.
- In particular, the
hinges 11 and 12 can optionally be provided by conventional pivots driven through bushes formed in theprotrusions - Another embodiment provides, in addition to the
wings 26 and thepins 27, or as a replacement thereof, a single wing 29 (see figure 2) rigidly coupled to thetab 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 thewall 32 of therecess 18 that joins thewalls 19. - Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly such reference signs do not have any limiting effect on the interpretation of each element identified by way of example by such reference signs.
