Definitions

  • This invention is concerned with improvements in and relating to retainers for closures and containers and in particular a retainer on a closure which will make locking engagement with a container and which closure is intended to be removable from the container only after detachment from the closure of a part of the retainer to release said locking engagement.
  • a retainer for retaining a closure and a container in closed condition, the retainer comprising a main flange which hingedly carries extension flange means which in turn carry retaining means, characterised in that the extension flange means and retaining means having a predetermined attitude relative to one another, the retainer, in an initial condition before the closure is applied to the container, has the extension flange means and retaining means in a first position relative to the main flange where they are clear of the path of relative movement of the closure and container in application of the closure to the container, the extension flange means and retaining means, whilst remaining in their predetermined attitude relative to one another are displaceable, after application of the closure to the container, relative to the main flange to position the retaining means in the path of the relative movement of the closure and the container in a direction of removal of the closure from the container,and a zone of weakening is provided in the retainer where a rupture can be effected to separate the extension flange from the container
  • the container or the closure may be a solid injection moulding or a composite article, that is to say an article which is at least in part a blank of card, board, foil or the like on which an injection moulding has been formed, in the case of a container to seam the blank and form a rim and in the case of a closure to create the rim.
  • the container or closure may also be thermo-formed or vacuum formed.
  • the zone of weakening is preferably a region of reduced thickness relative to the remainder of the rim, or perforations or both.
  • a circular closure which comprises a central region 1 having an upstanding wall 2, the closure having a retainer, here formed integrally with it and having a main flange 3 and extension flange means 4 having closure retaining means 5.
  • the closure and retainer are here shown as a one piece injection moulding but the central region could be a blank of card or the like as already described.
  • the extension flange means may be continuous around the closure or interrupted (as shown) and the retaining means are also preferably spaced apart.
  • the extension flange means In the initial condition of the moulding the extension flange means are in an attitude where they themselves are, and they hold the retaining means, clear of the path of relative movement of the closure and container as the two are brought to the closed condition.
  • the main flange 3 In the main flange 3 are two regions of weakening 6 formed by the moulding being of reduced thickness along two parallel paths, the region there between forming a tear band 7 which, in known fashion, is provided with a pull tab 8 which, on being pulled, will initiate rupture of the flange at a transverse line of weakening 9 and along the regions 6 to release the extension flange from the container.
  • the closure is placed over the container which itself is located below a closure tool 12.
  • the tool includes a punch 13 and a sleeve 14.
  • the punch and sleeve descend, the former to drive the closure into the container mouth and to initiate outward displacement of the extension flange means 4 and thereafter the sleeve moves down independently of the punch to complete the displacement of the extension flange means relative to the main flange until those flange means achieve the attitude shown in Figure 2 where the retaining means 5 while maintaining the same attitude to the extension flange means have reversed to now lie behind the bead 11, that is to say in the path of relative movement of the closure and container in the opening direction.
  • the retaining means 5 are contoured to merge into the initially inner surface of the extension flange means 4 thereby making illegitimate removal more 5 difficult by denying a purchase on the squared off junction between the retaining means and the extension flange means of Figures and 2.
  • the extension flange means where continuous or interrupted, may be corrugated to allow for the increase in length required to accommodate the displacement of the extension flange means from the initial condition before application of the closure to the retaining condition.
  • the closure retaining means may also be corrugated for the same reason.
  • Figure 4 Such an arrangement is shown in Figure 4 where the same reference numerals have been used for parts corresponding to the embodiment of Figures 1 and 2, the corrugations being indicated at C, and the extension flange means and retaining means being shown as continuous.
  • the closure is not readily replaceable to hide the fact that it has been removed unlawfully. It will require displacement of the flange means and retaining means to their initial relative attitudes, re-application of the closure and re- displacement of the flange means and retaining means, all without damaging the join between the closure and the retaining means.
  • a closure comprising a central region 20 having a main flange 21, a continuous extension flange 22 coupled to it through a zone 23 weakened by alternate perforations 24 and connections z5 themselves of reduced thickness, retainers 26 being carried by and spaced along the extension flange.
  • a tab 27 is coupled to the extension flange adjacent a starting weakened zone 28 and itself has a weakened zone 29.
  • the extension flange is displaced to the position shown in broken line where the retainers 26 engage behind bead 31 and the tab part 32 of tab 27 will take the same attitude and act as a retainer 26, while tab part. 33 of tab 27 will lie against the outer face of the container by virtue of zone 29 acting as a hinge.
  • zone 29 acting as a hinge.
  • To remove the closure tab 27 is pulled which will rupture zone 28 and thereafter zone 23 and thereby remove the retainers 26 and extension flange 22 progressively clockwise round the container and the main flange and allow removal of the closure.
  • the extension flange is progressively thickened towards the junction between it and the retainers 26 to encourage it to snap into and remain in the displaced retaining condition.
  • FIG. 6 there is shown a closure as in Figure 5, with the same references indicating like parts, but with no pull tab 27 or weakening 28, the arrangement of the extension flange 22 and retainers 26 being undisturbed by the presence of a pull tab. Instead a tongue is created by forming an elongate aperture A adjacent the root of the retainers, a similar aperture B in the root of the extension flange and a third aperture C in the extension flange extending between the ends of apertures A and B but spaced from each of them by bridges D. With such an arrangement, when the extension flange is urged from its initial position to the retaining position, the bridges D will snap to create a tongue T which can be used to break the zone 23. If desired a line of weakening L may be provided across the root of the retainers.
  • a container 40 having a moulded radial wall or step 41. Integral with the wall is a retainer including a main flange 42, from which in turn extends an extension flange 43 through a secondary extension 44 which is coupled to the main flange and extension flange by hinge pieces 45, 46. On the extension flange are retainers 47.
  • step 41 After the closure 48 has been placed on step 41, the secondary extension flange 44 and the extension flange 43 are displaced to a position respectively overlying and within the main flange with the retainers 47 bearing down on the closure, this situation being shown in broken lines.
  • the retaining means lie in the path of relative movement of the closure and container in the opening direction.
  • hinge pieces 45, 46 are formed by reduced regions and hinge part 45 may constitute the weakened zone which can be ruptured to allow removal of the extension flange and retainers or this zone may be formed at 49, appropriate pull tabs being provided but not shown here.
  • the container may be formed in any suitable fashion, that is as a composite or as a solid injection moulding or in any other fashion which will allow provision of the retainer described.
  • the mouth can be a moulding for application to a container as a separately made item.
  • a tongue 50 is created on extension flange 22 by providing a radial inward projection 50A on cavity tool C2 to whereby create an indentation 51 on the external surface 52 of the extension flange while a recess R is provided on the external surface of the core tool Cl to create a projection 53 on the internal surface 54 of the extension flange 22.
  • One circumferential end of the indentation 51 and the associated circumferential end of the projection 53 is created by a shut-off formed by the tools, resulting interruption 55 in the moulding extending axially of the lid, and creating a line of weakness in the moulding.
  • the other end of the indentation 51 on surface 52 is offset circumferentially, relative to the associated end of the projection 53 so that the tongue 50 is connected flexibly to the extension flange 22 at 56.
  • the depth, axially of the lid, of the tongue is less than the axial depth of the extension flange 22, the upper edge 50B of the tongue as viewed in Figure 8 being below the junction of the extension flange 22 and retainers 26 while the lower inner edge of the tongue is above or in the plane of the upper surface of the main flange 21 so that that lower inner edge of the tongue as viewed in Figure 8 is spaced from the upper outer edge of an edge recess 57 in the main flange produced by a part of the radially inwardly extending projection 51 on the cavity tool which part of the projection additionally interrupts the series of connections 25 provided between the main flange and extension flange.
  • Another part of the projection provides a weakening 60 in that part of the extension flange above and adjacent to the connection 56 of the tongue to the extension flange to allow the tongue to break the continuity of the moulding part carrying the retainers 26.
  • the series of spaced connections 25 and a pull tongue 50 which is pivotally anchored at one end to the extension flange, and will be outwardly accessible on the external surface of the extension flange, when the lid has been applied and turned over the edge of the container, whereby the extension flange can be pulled away from the main flange and container and thereby allow the lid to be removed.
  • the lid will still be in a condition to be re-applied to the container with the main flange still attached and serving to rest upon the lip of the container.
  • the core and cavity tools should part on the line 59. No blades or moving parts, particularly susceptible to wear and breakage and adding to cost in tool production, are required in either the core or cavity tool to create the pull tongue.
