Definitions

  • This invention relates to a container assembly including a cover for releasably closing a container of the assembly.
  • the cover is conveniently relockable.
  • the invention finds particular, though not exclusive application to closing containers of liquids, for example paint.
  • Cans of paint are often simply closed with a lid that has an outwardly-directed rim that is press-fitted into the top of the container. Removal of the lid may be made by means of insertion of the blade of a screwdriver and twisting to prise off the lid. The lid can subsequently be replaced to re-close the container, but usually the mating surfaces of the lid and container become damaged, and can become coated with dried contents of the container, with the result that a significant effort has to be exerted to re-close the container, and even then a seal may not be effected, which can cause spillage and/or deterioration of the contents
  • WO 03/062081 A1 discloses a relockable closure for a container, comprising a cover and a skirt that is foldable to lock the cover onto the container.
  • the closure requires a convoluted curl shape to be formed on the outside of the container at its rim.
  • a metal cover for the container is provided with a separate peripheral skirt attached thereto that depends downwardly therefrom and has a fold point that allows a curved rib to be deployed downwards so as to engage beneath the curl of the container.
  • a sealing compound is provided between the metal cover and the rim of the container.
  • the skirt may be separated into a plurality of sections by slits to facilitate its folding down around the outside of the container so as releasably to lock the cover thereon. It will be appreciated that this closure requires several components and complex shaping in order to be effective.
  • U.S. Pat. No. 3,688,942 discloses a simpler form of container and closure combination, in which the body of the container at its open end is shaped to provide a radially-outwardly and downwardly directed peripheral skirt portion.
  • the closure is also provided with a peripheral skirt portion with a plurality of locking members attached thereto by integral flexible hinge walls. The locking member members engage the free edge of the container skirt portion in a cam and cam follower manner so as to secure the closure to the container, with a compressible seal being provided therebetween.
  • U.S. Pat. No. 1,482,931 discloses a covered receptacle in which a can has a rolled-over rim and is closed by a cover having an annular depending flange.
  • a pair of spring-mounted levers are secured to the lower end of the flange diametrically opposite eachother, and are shaped to engage beneath the rim of the can to lock the cover thereon.
  • a container assembly comprising a container and a cover, wherein the container has a peripheral wall defining a rim enclosing an opening at one end thereof, and wherein the cover is provided for releasably closing the opening, the assembly being provided with at least one locking member that is hingeable between an unlocked position and a locked position, the at least one locking member having a locking member engagement feature which engages with a corresponding engagement feature on the cover and/or the container in the locked position to lock the cover to the container, in which the locking member passes over the rim of the container and/or a rim of the cover as the locking member hinges between the unlocked and locked positions such that the locking member locks onto the container rim.
  • a closure arrangement for a container wherein the container has a peripheral wall defining a rim enclosing an opening at one end thereof, and wherein a cover is provided for releasably closing the opening, the cover having a surface for extending over the opening with a periphery of the cover sitting on the rim of the container, and a skirt depending from the periphery to pass over the rim and to extend around the outside of the peripheral wall of the container, the arrangement comprising at least one hinged locking member that passes over the rim of the container to lock the cover thereonto.
  • hinging the locking member such that it passes over and locks onto the container rim ensures the cover is locked onto the container with a greater degree of security, and is therefore less likely to be accidentally released.
  • the cover of the closure arrangement thus comprises (i) a surface that closes the opening of the container and preferably with a periphery sitting on, and advantageously sealing onto, the rim of the container, and (ii) a skirt depending from the closing surface.
  • the or each hinged locking member is profiled so as to interengage with a complementarily-shaped profile on the container or on the cover so as to effect the locking of the cover onto the container.
  • the profiling may comprise interengaging projections, or interengaging projections and recesses.
  • the profiling may be provided on the inner and/or the outer surface of the container and/or the cover.
  • the hinging of the or each locking member may be located outside or inside the region defined by the peripheral wall of the container.
  • the or each locking member may be formed integrally with the cover or the container, being hinged thereto by a living hinge.
  • the closing surface of the cover is arranged, at least upon closure of the locking member(s), to provide a seal onto the container.
  • the locking members are hinged so as to close upwardly over the rim of the container so as to dispose their free ends within the area defined by the rim, thereby to reduce the risk of unintentional release.
  • the free ends of the locking members may lie substantially flush with the upper surface of the cover, or at least be disposed below the level of the rim.
  • the locking members may be hinged within the periphery of the container rim so as to close downwardly around the outside of the container, preferably with their free ends lying closely adjacent thereto.
  • a closure arrangement for a container wherein the container has a peripheral wall defining a rim enclosing an opening at one end thereof, the peripheral wall having at least one outwardly-directed projection extending at least partially around the outer surface of the wall adjacent the opening, and wherein a cover is provided for releasably closing the opening, the cover having a surface for closing the opening of the container and a skirt depending from the closing surface to enclose the projection of the container, the skirt being provided with at least one hinged locking member that has (a) an inwardly-directed projection for co-operating with the outwardly-directed projection of the container, and (b) a lip for passing over the rim of the container at the opening thereof and engaging onto the closing surface, thereby to lock the cover to the container, with the respective inwardly- and outwardly-directed projections engaging with each other.
  • the at least one projection of the container is longitudinally spaced apart from the rim thereof in a direction away from the container opening.
  • a container assembly comprising a container and a cover, wherein the container has a peripheral wall defining a rim enclosing an opening at one end thereof, and wherein the cover is provided for releasably closing the opening, the assembly being provided with at least one locking member that is hingeable between an unlocked position and a locked position, the at least one locking member having a locking member engagement feature which engages with a corresponding engagement feature on the cover and/or the container in the locked position to lock the cover to the container, in which the locking member hinges upwardly from the unlocked to the locked position
  • a snap-fit connection With locking of the container being brought about by an upward movement of the or each locking member to effect, preferably a snap-fit connection, there is less likelihood of the locking member being inadvertently moved to the unlocked position when a user picks up the paint container, since usually the user will pick up the container in an upwards movement which contrasts to the downwards movement required to unlock the locking member, and therefore release the cover from the container. If the snap-fit connection is over the rim of the container onto itself or onto the rim of the container, the free ends of the or each locking member may be safely and visibly contained within the periphery of the container, thus further mitigating against accidental release.
  • the closure arrangement of the present invention requires comparatively few components, comprising in its most basic form, a suitably-shaped rim of a container, and a cover that serves to close the container and to effect locking thereonto by one, or more, integral hinged locking members.
  • the cover and the skirt are preferably formed integrally with one another, and the or each locking member is preferably formed integrally with the skirt, preferably being hinged thereto by a live hinge.
  • the or each locking member may be secured to the skirt by a respective separate hinge.
  • a window is formed in the skirt at the peripheral location of the or each locking member, whereby upon locking the cover onto the container, the locking member fits into its window and the respective inwardly- and outwardly-directed projections engage each other directly.
  • cover and the container in the absence of any liner, will be in contact with the contents of the container, they will be made from a relatively inert material.
  • they may be made of a plastics material, preferably by moulding. These parts may be made by a comparatively inexpensive blow moulding process using polyethyleneteraphthalate, for example.
  • metal may be used in appropriate circumstances.
  • the or each locking member may be recessed into an otherwise substantially planar top surface of the cover, to provide further protection against accidental release of the closure arrangement from the container.
  • three locking members are provided for a closure arrangement of generally circular configuration, being equi-spaced around the cover, although two, or four or more, may be used if required.
  • the configuration is rectilinear, then it is envisaged that at least one locking member would be provided for each side of the arrangement, or alternatively, a locking member may be provided at each corner of the container.
  • the outwardly-directed projection on the surface of the container extends continuously therearound, thus allowing the cover to be fitted thereto in any orientation, it is envisaged that it may be provided by a plurality of discrete sections. In the latter case, the number of sections would advantageously be the same as the number of locking members, thus requiring the cover to be appropriately positioned on the container in order to effect locking therebetween.
  • the exterior of the base of the container is provided with one or more recesses to facilitate gripping thereof by a user.
  • FIG. 1 is a plan view of the assembly with two locking members thereof in the locked position and a third locking member in the unlocked position,
  • FIG. 2 is a sectional elevation on the line A-A of FIG. 1 showing the cover in the unlocked position
  • FIG. 3 is a sectional elevation on the line B-B of FIG. 1 , showing the cover in the locked position
  • FIG. 3A is a sectional elevation on the line B-B of FIG. 1 , showing the cover in the locked and unlocked position
  • FIG. 4 is a plan view of the top of another embodiment of the container assembly
  • FIG. 5 is a sectional elevation on the line C-C of FIG. 4 , showing the assembly in the locked position
  • FIGS. 6 to 15 are sectional elevations of alternative embodiments showing the container assembly in the locked and unlocked positions.
  • FIG. 16 is an underneath view of a container of the container assemblies of FIGS. 1 to 15 .
  • a cylindrical container 2 made of a plastics material for containing paint, is closed by a moulded plastics cover 4 .
  • the container 2 has a projection 6 extending circumferentially therearound on its outer surface, adjacent a rim 8 at its open end.
  • the cover 4 has a planar dished upper surface 10 that sits within the container rim 8 , and has three hinged locking members 12 equi-spaced therearound which are set into a downwardly depending skirt 14 of the cover 4 .
  • the cylindrical inner surface of the skirt 14 is of such a diameter as to form a sliding fit over the circumferential projection 6 on the outside of the container 2 .
  • Each locking member 12 is formed integrally with the skirt 14 and can be hinged away from the lower circumferential edge 16 thereof by means of a live hinge 18 ( FIG. 2 ) exposing a window 15 in the skirt 14 .
  • the hinged portion of the locking member 12 is of generally L-shape, having a lower part 13 extending away from the hinge 18 that is provided adjacent thereto with an inwardly-directed projection 20 , of generally the same size and shape as the container projection 6 .
  • the projections 6 and 20 are longitudinally displaced from the upper ends of the container 2 and cover 4 respectively, such that when the locking member 12 is moved from its unlocked position ( FIG. 2 ) to its locked position ( FIG. 3 ), the locking projection 20 engages the outer wall of the container 2 immediately below its projection 6 .
  • the upper part 22 of the locking member 12 passes over the container rim 8 with its free hooked end 24 snap-fitting over a locally-thickened wall portion 26 of the raised rim 27 of the cover 4 .
  • This engagement of the locking member 12 onto the upper rim of the cover 4 whilst simultaneously bringing the projections 6 and 20 into engagement, is effected as a snap action, thus providing an audible indication that the cover 4 has been properly secured onto the container 2 .
  • the locking member 12 is locked onto the rim 8 of the container, and therefore retained in the locked position by virtue of the snap-fit between the hooked end 24 and the thickened wall portion 26 , and with the locking member in the locked position, the cover is retained on the container by virtue of the engagement between the projection 20 on the locking member 12 and the projection 6 on the container rim.
  • FIG. 3A shows in more detail the interaction between the locking member 12 as it moves upwards from the unlocked position (shown dotted) to the locked position. It can seen from a comparison of the locked and unlocked positions that the locking member 12 passes over the rim 8 of the container and locks onto the rim of the container 8 due to the engagement between the thickened wall portion 26 of the raised rim 27 of the cover and the hooked end 24 of the locking member 12 . It should be noted that in this embodiment the raised rim 27 of the cover is between the container rim and the locking member 12 , and that the locking member 12 locks onto the container rim indirectly by locking onto the raised rim 27 which then locks onto the container rim 8 . By locking the locking member onto the container rim in this way, the cover is retained with a greater degree of security onto the container.
  • the hinging of the locking members 12 on the cover skirt 14 is on the outside of the container 2 , and thus is not, in normal use, contacted by the container contents. Thus there is no interference of the locking members 12 by the contents of the container 2 .
  • FIG. 4 shows a top plan view and FIG. 5 shows a sectional elevation along line C-C of a modification of the assembly of FIGS. 1 to 3A .
  • a circular cover 30 for the container (not shown) has three hinged locking members 32 equi-spaced therearound, shown in the locked position.
  • the central cover surface 34 is not dished, but is substantially flush with the upper surface 33 of the locking members 32 .
  • the surface 34 is, however, provided with a scalloped region 36 adjacent each locking member 32 , with the locking member 32 extending partially over the scalloped region 36 so as to facilitate lifting thereof for hinging the locking member 32 towards the unlocked position such that the cover 30 can be removed from the container.
  • the planar top to the cover, with the recessing of the locking members further mitigates against accidental opening of the container.
  • the cover is retained on the container in the same manner as described in relation to the assembly of FIGS. 1 to 3A .
  • FIG. 6 there is shown an alternative assembly which is identical to the assembly of FIGS. 1 to 5 except that the container rim 227 is not locally thickened.
  • the cover is retained on the container in the same manner as described in relation to the assemblies of FIGS. 1 to 5 except that the locking member 232 is locked onto the container by engagement of the locking member projection 224 with the inside surface 235 of the container rim 227 .
  • FIG. 7 there is shown an alternative assembly which is identical to, and operates in the same way as the assembly of FIG. 6 except that in this embodiment the live hinge 318 is positioned at a lower edge of the skirt 314 as opposed to being spaced from the lower edge.
  • the live hinge 318 is positioned at a lower edge of the skirt 314 as opposed to being spaced from the lower edge.
  • FIG. 8 there is shown an alternative assembly, which is identical to, and operates in the same way as the embodiment of FIG. 7 except that the cover rim inside surface 435 and the locking member projection 424 are profiled such that the projection 424 snaps into a recess 436 defined by the cover rim inside surface 435 .
  • This arrangement provides a more pronounced snap-fit, and thus a greater force is required to disengage the locking member projection 424 from the container rim recess 436 when moving the locking member 432 from the locked position to the unlocked position in comparison to the embodiments of FIGS. 1 to 7 .
  • the cover is secured to the container with a greater degree of security.
  • FIG. 9 there is shown an alternative assembly which is identical to the embodiment of FIG. 8 except that firstly, the recess 536 is defined in the container rim and not in the cover rim, and secondly, no projections are provided on the skirt and on the outside of the container rim.
  • the locking member projection 524 snaps into the recess 536 to retain the locking member 532 in the locked position.
  • the cover is locked to the container by direct engagement of the locking member 532 onto the container as opposed to the cover.
  • the container is made of a material which is more rigid than the cover.
  • the cover rim 527 is modified such that it does not extend upwards greater than the projection 524 extends downwards.
  • projections 524 and the recess 536 prevents the cover from being removed from the container when the locking member 532 is the locked position. For this reason, there is no requirement for projections on the skirt and the outside of the container rim.
  • projections can be included on the skirt and on the outside of the container rim as already described in relation to the assemblies of FIGS. 1 to 8 if it is desirable to provide an even more secure retention of the cover onto the container.
  • the recess could be provided on the locking member projection, for cooperation with a corresponding projection on the inside surface of the container wall. It would also be possible to provide corresponding engagement features on the cover and the container by profiling the rim sections such that they engage in the locked position.
  • the locking member 632 includes an aperture 650 which defines an inside edge 651 and an outside edge 652 , and allows a corresponding portion 653 of the cover rim to extend therebetween.
  • the aperture is sized such that it forms a close fit with the portion 653 of the cover rim, but does not prevent the locking member 632 from hinging between the locked and unlocked positions.
  • the inside edge 651 is positioned such that when the locking member 632 is in the locked position there is engagement between the inside edge 651 of the locking member 632 and the inside surface 657 of the corresponding portion 653 of the cover rim.
  • the inside edge 651 of the aperture which is acting as the engagement feature, and the locking member 632 is retained in the locked position by the snap-fit between the inside edge 651 of the aperture and the corresponding portion 653 of the cover.
  • the provision of the outside edge 652 of the aperture also provides a more secure locked position of the locking member 632 since movement of the locking member is prevented by engagement of the cover portion 653 with the outside edge 652 .
  • FIG. 12 there is shown an alternative assembly which is identical to the assembly of FIGS. 10 and 11 except that in addition to the inside edge 751 of the aperture 750 engaging with the cover, a projection 724 is provided on the cover adjacent to the aperture so as to provide a greater engagement area, and therefore a more secure retention of the locking member onto the cover.
  • the assembly of FIG. 12 can be considered as a combination of the embodiments of FIGS. 7 and 11 .
  • FIG. 13 there is shown an alternative assembly which is identical to the embodiment of FIG. 7 except that an additional projection 860 is provided on the locking member 832 , and the cover inside rim 827 is extended radially outwardly such that it can engage with the additional projection 860 when the locking member is in the locked position.
  • the provision of the additional projection 860 provides a more secure locked position in the same way as described in relation to the embodiment of FIGS. 11 and 12 , except that in this embodiment edge 652 is replaced by the projection 860 , and edge 651 is replaced by projection 824 .
  • FIG. 14 there is shown an alternative assembly which is identical to the assemblies of FIGS. 6 and 7 except that the hinge 918 is provided on the cover surface 934 and not on the skirt 915 .
  • the hinge 918 is provided radially inward of the rim 908 of the container. The locking member is locked onto the cover, and the cover locked onto the container in the same manner as described in relation to the assemblies of FIGS. 6 and 7 , except that it is the projection 920 on the locking member skirt which snap-fits below the projection 906 on the outside of the container rim.
  • the hinge inward of the container rim it is possible, in an alternative embodiment, to remove the projection 924 altogether such that the locking member 932 is locked onto the container rim due to the snap-fit generated by engagement of projection 906 and projection 920 as the locking member hinges downwards about hinge 918 to the locked position.
  • the cover is retained on the container due to the engagement between projection 906 and projection 920 .
  • the provision of the hinge 918 inside the container rim enables the projections 906 , 920 to both lock the locking member onto the rim, without the need for projection 924 , and retain the cover on the container.
  • the provision of projection 924 on the locking member 932 will lock the locking member onto the container with a greater degree of security.
  • FIG. 15 there is shown an alternative assembly which is identical to that of FIG. 14 except that the locking member 1032 engages directly onto the container rim 1008 and not onto the cover rim.
  • FIGS. 14 and 15 It can be seen from the embodiments of FIGS. 14 and 15 that it is the provision of the hinge radially inward of the container rim which enables the locking member to hinge such that it passes over the rim of the container, and allows the locking member to lock onto the container rim.
  • FIG. 16 shows the underside of a container 40 in which a scalloped region 42 is moulded or otherwise indented into the base to facilitate gripping of the container by a hand during use.
