Definitions
- An improved container-closure arrangement is disclosed, for example, an arrangement wherein at least the closure is moulded from plastic and which is adapted when assembled to be resistant to closure removal when dropped, and to be resistant to pilfering (eg. to be tamper proof) etc.
- US 5,979,691 discloses a plastic container of rectangular shape, with lid 12 having members 24 extending therefrom. Each member has a latch 26, which latches into an aperture 32 of container wall 30.
- US 6,021,917 discloses a plastic container of circular shape with an arrow-like projection 7 extending from lid 1.
- the projection 7 extends through and is latched into orifice 15 of pail latch 14.
- WO 02/30780 discloses a bead-latch arrangement at the upper end of a container rim for attaching a closure to the container, hi addition, WO 02/30780 discloses additional means of securing a remote end of an external skirt of the closure to a projecting flange of the container.
- a container-closure arrangement comprising: (i) a container having a base, a peripheral wall, a rim forming an upper margin of the wall and surrounding an opening of the container, and a flange formed integrally with and extending out from the wall below the rim;
- a closure having a central portion that is arranged to overfit the opening of the container, a skirt formed integrally with the central portion and arranged to surround the rim when the closure is fitted to the container, the skirt being positionable adjacent to the flange when the closure is fitted to the container;
- each projection typically comprises a portion that is deflectable relative to a remainder of the projection by the corresponding formation of the flange such that, once inserted into the opening, the formation maintains the portion in a deflected orientation to thereby resist projection removal from the opening.
- the formation of the flange causes the projection portion to assume an orientation wherein removal of that projection from the opening is resisted.
- each projection typically comprises a recess or aperture into which the formation of the flange can extend such that, when the projection is inserted into the opening, the formation is first deflected by the projection until it aligns with the recess or aperture and, once so aligned, moves into the recess or aperture such that the projection then resists removal from the flange.
- the recess or aperture defines the corresponding formation of the projection, and thus it is the recess or aperture that causes the formation of the flange to assume an orientation wherein removal of that projection from the opening is resisted.
- portion or corresponding formation can be formed at or on the container and may project therefrom to interact with the projection once it has been inserted into the flange opening, although this embodiment may be less easy to manufacture (eg. mould) then the embodiment in which the portion or corresponding formation is formed at or on the flange.
- the closure could comprise a single skirt (eg. where the projections permanently attach the skirt to the flange), typically the skirt comprises two or three skirt portions frangibly coupled together, with each projection extending from a distal end of the distal skirt portion.
- frangibly coupled skirt portions can thus provide a ready means of closure removal.
- a middle one of the skirt portions can define a removable tear strip. Removal of this tear strip then frees the closure for removal from the container.
- a line of severance between these portions can be defined. Severance along this line then frees the closure for removal from the container.
- the deflectable portion once deflected, typically assumes a locking position whereat the projection is locked in and against the flange, thereby locking the closure to the container.
- the deflectable portion whilst the deflectable portion may lock at partial insertion of the projection into the opening, typically it locks at full projection insertion.
- the corresponding formation of the flange can comprise a discrete protrusion formed within the flange, or it may simply be defined by an internal wall of the flange, or an external wall of the container. Once inserted into the opening typically the deflectable portion is deflected laterally towards or away from the container wall, and into a latching position with respect to the flange.
- each projection may be defined by a tab extending from the skirt, with the deflectable portion then comprising a tongue formed within the tab.
- the tongue can be attached along one of its edges to a remainder of the tab to define a tongue hinge.
- the tongue in profile, can have the same thickness as the remainder of the tab.
- the protrusion can then be a boss formed integrally with and projecting out from an inner wall of the flange within the opening, or can project out from an external wall of the container.
- the boss engages against the tongue and deflects it into a locking position with respect to the flange.
- the boss is generally dome-shaped to facilitate tongue movement therepast, or may be defined as a ridge.
- the tongue in profile, can have a thickness greater than the remainder of the tab.
- the internal wall in the flange opening can then be located to deflect the tongue into a locking position once the projection has been inserted into the opening.
- the tongue in profile, can taper outwardly from tongue hinge such that, as the projection is inserted into the opening, the tongue interferes with and is deflected by an internal wall of the flange into a locking position.
- the tongue can interfere with and be deflected by an external wall of the container to cause the tongue to pivot into a locking position. In either case, the tongue may be deformed as it is inserted into the opening.
- the formation can be defined as a latch which, in profile, tapers outwardly from a location adjacent to an entrance to the opening, to a location remote from the opening entrance.
- the remote part of the latch can define a shoulder, with the latch taper facilitating projection movement therepast until the latch aligns with and then moves into the recess or aperture, such that an edge of the recess or aperture latches under the shoulder. This latching thus locks the projection within the flange.
- each projection can again be defined by a tab extending from the skirt, but in this embodiment the recess or aperture is now defined centrally within the tab.
- the flange extends peripherally right around the container wall, although it can be provided as respective discrete flanges corresponding in location to each projection when the closure is mounted to the container.
- the skirt or a distal skirt portion can be adapted for fastening at the flange. This fastening may provide additional fastening between the closure and container to that provided by the projections.
- the closure and container configurations depicted in WO 02/30780 can be employed together with the projection arrangements defined and described herein.

- a container-closure arrangement comprises a container in the form of generally square-bottomed pail 10, and a closure in the form of lid 11.
- a pivotable handle may be connected to the container at opposing holes 12 for ease of handling.
- the pail and lid are typically moulded from a polymer, and may be moulded from eg. polypropylene or high density polyethylene.
- the pail can be formed from metal (eg. steel).
- the handle may be formed from steel or a plastic material.
- the pail may be moulded in any desired size and can have a volumetric capacity in the order of 4 to 25 litres.
- WO 02/30780 the relevant contents of which are incorporated herein by reference.
- the pail 10 has a base 13 which can be sized to locate within a well 14 of the lid, so that a number of assembled pail-lid arrangements may be stacked one upon another.
- the pail has a peripheral wall 15 and, as shown in Figure 2, a rim 16 forms an upper margin of the wall 15 and surrounds an opening of the pail.
- a bead 17 is formed integrally with and either surrounds the rim 16 or is provided as discrete bead segments around the rim.
- the bead has an undersurface 18 ( Figure 3C) that extends from the outer surface of the peripheral wall 15.
- An annular flange 19 is formed integrally with and typically surrounds the peripheral wall 15 of the container, although a number of discrete projecting flanges can be provided as an alternative.
- the flange is located below the level of the bead 17 and typically comprises two wall portions 20 and 21.
- the wall portion 20 can be inclined with respect to the peripheral wall 15 of the container ( Figures 1 to 5) or may project orthogonally therefrom (as in the arrangements of Figures 6 to 8).
- the wall portion 21 typically depends from the outer margin of the wall portion 20.
- a rebate 23 can be formed in the flange at the junction of the two wall portions 20 and 21 to assist with tamper-proofing the join between lid and pail.
- the lid 11 may comprise a continuous (unbroken) depending skirt extending peripherally therearound, typically the skirt comprises a number of skirt portions.
- the lid comprises a first skirt portion 26, a second skirt portion 29 and typically a third skirt portion 31.
- the first skirt portion 26 is formed integrally with the central portion 25 and is sized to surround and engage the pail bead 17. Thus, whilst the first skirt portion 26 can extend right down to the flange when the lid is mounted to the pail (and thus define a continuous depending skirt), typically it is connected to the further skirt portions (as described below).
- An annular ledge 27 is located within and is formed integrally with the first skirt portion 26, and the ledge 27 is positioned to locate in interlocking engagement with the undersurface 18 of the bead 17 when the lid is mounted to the pail.
- the ledge 27 may accordingly be formed as corresponding ledge segments around and within the first skirt portion 26.
- the first skirt portion 26 may be shaped to flare outwardly from the ledge 27, to provide for subsequent access to an internal surface 28 that is profiled with gentle curves to accommodate the fingers of a person who seeks to lift the lid from the pail (ie. after tear strip removal — described below). This shaping also facilitates a sliding inter- engagement of the lid and the pail when the lid is pushed onto the pail.
- the bead 17 may be shaped as shown to facilitate sliding engagement between the lid and the pail when the lid is pushed onto the pail.
- the second skirt portion 29 depends from and is frangibly connected to first skirt portion 26 by way of an integrally moulded thin connecting web 30.
- the third skirt portion 31 is provided as an extension of the second skirt portion 29 and is frangibly connected thereto by an integrally moulded web 32.
- the frangible connection together of skirt portions 26, 29 and 31 thereby define the second skirt portion 29 as an easily removable tear strip.
- the second skirt portion 29 may also be formed with an integral tear tab 37 for initiating tear strip removal.
- the third skirt portion 31 can locate within the rebate 23 of the flange 19, to provide a tamper-proof join between the Kd and pail.
- the third skirt portion 31 may also be thermally or chemically bonded in that rebate 23.
- projecting rim 50 of the third skirt portion 31 is typically push-fitted (Figure 3C) into and locks in a groove 52 of the container flange 19. after the container has been charged with material, and as the lid 11 is mounted to the pail 10 for the first time. Again reference is made to the relevant description of the applicant's patent application WO 02/30780.
- a discrete projection in the form of generally rectangular tab 70 or 70' respectively is shown in a cut-away perspective view through the lid 11.
- a plurality of tabs 70 or 70' are intermittently located along each side of lid 11, to project downwardly therefrom.
- Figure 2 shows four such tabs being arranged along each side of lid 11.
- each tab 70 or 70' is integrally moulded with the third skirt portion 31 to project downwardly therefrom as shown, and replaces projecting rim 50 for the length of the tab.
- a corresponding tab recess 72 for each tab is defined in the flange 19 and replaces a corresponding length of the groove 52.
- the recess 72 for a given tab is typically located in the flange adjacent to and aligned with the groove 52. Whilst the recess 72 can be defined separately from groove 52, typically it is contiguous therewith.
- the tab 70 may also project downwardly from a single unbroken skirt (eg. where second skirt portion 29 defining a tear strip is not provided) or it may subtend directly from second skirt portion 29 (eg. where the third skirt portion 31 is not provided).
- an aperture 73 is defined in the tab 70 as shown. The aperture 73 can receive therein a protrusion from the flange 19 when the tab has been inserted into its recess 72, as described below.
- an alternative tab 70' is provided with an integral tongue portion 74, which is deflectable, relative to a remainder of the tab, about a hinge line HL, when the tab has been inserted into its recess 72, as described below.
- the tabs 70,70' are provided with a bevel face 76 to facilitate and guide tab insertion into tab recess 72.
- a bevel face 76 to facilitate and guide tab insertion into tab recess 72.
- tab 70 is shown prior to insertion ( Figure 4A) and after having been inserted into tab recess 72 ( Figure 4B). Insertion is assisted by bevel face 76 which defines a relatively narrower insertion end 78 of the tab. To further assist tab insertion the opening to recess 72 can be flared outwardly at 80.
- the aperture 73 is shaped to receive a protrusion in the form of a locking lug 81, the lug 81 being integrally formed with and projecting from a depending inner wall section 82 of flange 19.
- the locking lug 81 projects into the aperture 73 such that tab inner edge 83 is located and captured behind a shoulder 84 defined at an in-use lower end of lug 81.
- lug 81 tapers outwardly down to shoulder 84.
- This outward tapering facilitates movement of tab end face 78 past lug 124, and typically causes the flange inner wall section 82 to flex inwardly until the lug registers with aperture 73, and the tab inner edge 83 has moved past the shoulder 84.
- the flange inner wall section 82 is caused to snap back outwardly away from the pail wall, to lock tab inner edge 83 under shoulder 84.
- the faces of tab inner edge 83 and shoulder 84 are parallel to each other and are respectively inclined.
- an inside face of flange wall portion 21 is provided with a protrusion in the form of generally dome-shaped boss 85.
- the boss 85 is located such that, as tab 70' is inserted into recess 72, the boss engages against tongue 74.
- the boss causes tongue 74 to be urged against the flange inner wall section 82 so that it flexes inwardly until the tongue moves past an inset lower edge 86 of wall section 82 (ie. defined by a cut-away section of wall section 82).
- the tongue 74 is caused to snap inwardly (in the direction of arrow P, the tongue pivoting around hinge line HL) and flange inner wall section 82 is caused to snap outwardly away from the pail wall. This locks an upper edge of tongue 74 under wall section lower edge 86. The boss 85 then maintains the tongue 74 in this position, thereby preventing tab removal from recess 72 (eg. when an upward force is applied to lid 11).
- the tongue may be configured to assume the locking position earlier than full tab insertion (eg. by shortening the tongue or extending up the cut-away section of wall section 82).
- an alternative pail 10' and lid 11 ' is shown employing an alternative tab mounting arrangement.
- This arrangement can be employed for straight- sided containers, such as metal cans etc.
- the flange 19 comprises an outer wall portion 21 subtending from a laterally (eg. orthogonally) extending wall portion 20.
- the skirt portions 26 and 29 sit flush against the wall 15 of pail 10' at rim 16.
- the second skirt portion 29 is provided as a more pronounced tear strip 87, and tab 70 is connected to the second skirt portion 29 via web 32 (rather than to a third skirt portion 31 , which in this embodiment is not required).
- the bead 17 is formed to protrude inwardly of rim 17 so that ledge 27 instead projects inwardly from the central portion 25 of lid 11 ' .
- the first skirt portion 26 is provided with a peripheral ledge 88 to facilitate press fitting of the lid 11" onto pail 10" (eg. by a ring press tool) and to facilitate removal of the lid once tear strip 87 has been removed (eg. by finger or tool).
- a boss 85' is formed to project outwardly from pail wall 15 and is typically moulded or formed integrally with the wall. Tongue portion 74 is also adapted to pivot laterally outwards from pail 10' in use.
- the tongue portion 74 at least is formed from a deformable material to facilitate its insertion into recess 72.
- that part of the flange surrounding tab recess 72 can be formed from a deformable (eg. polymeric) material and/or can be deflected during insertion.
- a cut-away groove 90 can be provided along the hinge line HL, where the tongue portion is attached to the remainder of tab 70.
- bevel 76 is now provided on an opposite side of tab 70, the bevel again facilitating tab insertion into recess 72, but also facilitating tab movement around boss 85' (ie. preventing an inner sharp edge of tab end 78 from catching on boss 85' during tab insertion).
- tongue 74 During tab insertion into recess 72, the tongue 74 primarily bends and deforms to enable such insertion. When the tab has been fully inserted as shown in Figure 6, tongue 74 is deflected to locate under flange underside face 92, thereby locking the tab in recess 72 and preventing removal of lid 11 ' from pail 10'.
- tab 70' has been modified by replacing tongue portion 74 with an enlarged tongue portion 94.
- enlarged tongue portion 94 is wider at its remote (distal) end 96 relative to the remainder of tab 70".
- the tongue portion 94 at least is formed from a deformable material to facilitate its insertion into tab recess 72.
- that part of the flange surrounding tab recess 72 can be formed from a deformable (eg. polymeric) material to deform and/or to be deflected during tab insertion into recess 72.
- tongue portion 94 rides against an external face of pail wall 15. During such insertion the tongue portion 94 may deform, as may wall portions 20 and/or 21, as the tab moves through the opening at 80. When the tab has been fully inserted into recess 72, the external face of pail wall 15 urges tongue 94 back to its outwardly pivoted position, and maintains it in this position. This is a similar locking position to that assumed by the tongue 74 in Figure 6, and thus the tab is locked in recess 72 and the removal of lid 11 ' from pail 10' is prevented.
- Each of the various tab embodiments described effectively lock the lid to the pail and enable an assembled lid-pail arrangement to meet the various drop test requirements of countries across the world (including various south-east Asian countries) whilst enhancing tamper-proofing.
- the resultant lid-pail mounting can also resist lid removal due to inadvertent bumping, sharp blows etc that occur during production, transportation and in use.
- lid-pail arrangements can be embodied in many other forms.
