Definitions

  • the present invention relates to a relockable closure for a container, in particular for metal containers for storage of e.g. chemicals/solvents.
  • a non-plastic container so as to avoid leakage due to the solvents dissolving of the material of the container.
  • oil-based paint needs to be stored in a non-plastic container, such as a metal container. Opening of a metal container is very difficult, as it often requires a sharp-pointed article (e.g. a screwdriver) that can be stuck in between the cover and container so as to lift the cover. Further, the closing of such container requires a relative high pressure on the cover (or even use of a hammer) in order to press the cover tightly into the opening of the container.
  • WO 01/44069 describes a resealable closure for an open topped container.
  • the closure includes a metal lid for closing the container opening and a plastic ring secured to the metal lid.
  • the plastic ring includes at least one element for engaging a radially outward formation of a container to retain the metal lid in sealed engagement with the container.
  • the plastic ring further includes a depending portion extending exteriorly of the container and wherein manual manipulation of the depending portion facilitate removal of the closure from the container.
  • the present invention relates to a relockable closure according to claim 1.
  • the container and cover may be cylindrical, oval or elliptical, or it may be a polygonal container, such as quadrangular or rectangular.
  • the skirt may extend along an outer surface of the curt portion and engage an edge of the curl portion and/or the projections, which may be outwardly extending beads/corrugations in the sidewall of the container.
  • the dosure may comprise one non-metallic skirt.
  • the closure may comprise a plurality of non-metallic skirts such as two or three or four or five or six or seven or eight or nine or ten.
  • the non-metallic skirts may be attached to each other or may be detachable from each other e.g. by means of a weakning line in the skirt.
  • the skirt comprises a first part attached to the cover and a second part being foldable between a locking position where said locking means engages said curl portion and/or projections and an unlocking position where said locking means is out of engagement with said curl portion and/or projections.
  • the skirt comprises a fold line around which the second part may be swung outwards and upwardly when going from the locking to the unlocking position. In the unlocking position, the second part may abut the first part.
  • Said curl portion may define contact surfaces for said cover and locking means.
  • the locking means comprises a peripherally extending rib engageable with a part of said curl portion and/or projections.
  • the rib may be formed with a curved portion having a radius, which corresponds to the radius of a curved part of said curl portion and/or projection.
  • the skirt may comprise a resilient rib, e.g. made of rubber, which engages the part of the curl portion and/projections.
  • the skirt extends continuously along the entire circumference of the container (if the container is cylindrical, oval, elliptical or polygonal), but as an alternative the skirt may consist of two or three or four or more individual skirts, so that the cover is locked to the container by individual non-connected skirts.
  • At least a part of the locking means may be detachable.
  • a part of the engaging rib may be detachable.
  • the detachable part of the locking means/engaging rib may be adapted to provide an enhanced engagement with the curl portion or the one or more projections of the container compared to the non-detachable part of the locking means/engaging rib.
  • it may be easier to remove the closure.
  • it may still be necessary to twist or flip the non-detachable part of the locking means/engaging rib during removal of the closure.
  • the locking means/engaging rib may comprise a first part and a second part, wherein the engaging surface of a cross-section of the first part is bigger than the engaging surface of a cross-section of the second part.
  • the thickness of a cross-section of the first part may be thicker than a cross-section of the second part. Due to the thicker part, the engaging surface may be bigger or it may be harder to twist the engaging rib past the curl portion or the one or more projections.
  • Said first part may be detachable.
  • the closure may comprise gripping means adapted to make it easier for the user to remove the closure.
  • the gripping means may serve as a handgrip and the position of the hand grip may result in enhanced or reduced engagement between the closure and the container.
  • the gripping means may also be adapted to make et easier to attach the closure to the container.
  • the closure may comprise one or two or more gripping means.
  • the gripping means may be adapted to be used as handles during transportation of the container.
  • said skirt may comprise one or more peelable perforations extending transverse to the circumferential direction of the skirt.
  • the skirt may also comprise one or more slits (not perforated) extending transverse to the circumferential direction of the skirt.
  • the slits and/or perforations extend in the second part of the skirt only, but they may extend in both the first and second part of the skirt.
  • the skirt is seamed to the cover, so that the skirt is seamed in between two oppositely arranged flanges.
  • the cover may comprise a wall portion engageable with an internal surface of the container defined by its sidewall, said wall portion and skirt defining a cavity for said curl portion of the container.
  • the wall portion may be outwardly inclined, so that the wall portion and the internal surface of the container may frictionally engage each other so that the cover is maintained in its position in the opening of the container even if the skirt is not in its locking position.
  • the cover may comprise a plane cover surface extending substantially perpendicular to the sidewall of the container and without extending into the container, so that the above-mentioned wall portion may be dispensed with. In that case the cover may be locked to the container by means of the skirt only.
  • the internal surface of the container may comprise corrugations, which prevents a capillary rise of the content in the container so as to avoid the contents to run out of the container.
  • a compound (a material for providing a sealed/tight closure) may be placed between the cover and the container.
  • the compound may e.g. be a rubber band or a band of silicone sprayed on or an elastomer or a soft polymer or a synthetic rubber composite.
  • the compound may be placed between the sidewall of the container and said wall portion of the cover, such as inside a corrugation in the sidewall of the container or the wall portion.
  • the compound may be placed between the skirt and the sidewall of the container, such as inside a corrugation in the sidewall of the container or on the second part of the skirt.
  • the compound may e.g. constitute the above-mentioned rib, or the compound may just be attached to said cover or skirt.
  • the cover is made of metal, but it can be made of cardboard or composites or glass or wood.
  • the skirt is preferably made of a resilient/flexible plastic, such as PELD or PP or PEHD or PET or PMMA or PA or elastomers or rubber.
  • closures with a metal cover may be inflexible compared to plastic covers.
  • solidified material on an internal surface may not come off in flakes when the closure is detached or re-attached, as metal covers may not be twist or bent to the same extend as plastic covers.
  • a skirt made of a flexible material may provide the foldable properties of the present application. As the skirt is foldable it may be possible to provide an enhanced engagement between a rib portion of the skirt and an edge of the can. This is due to the fact, that the closure need not to be adapted to be pulled off the can when the rib portion of the skirt and the edge of the can are engaged.
  • the container may contain foodstuff, solvents, chemicals, paints as the cover provides a tight and lockable closure, but the container and cover may of course also be used for other goods, such as cookies.
  • the container may be made of metal, plastic, composites, cardboard glass or wood.
  • the second part of the skirt When taking off the closure from the container, the second part of the skirt may be folded/swung into the unlocking position and subsequently the closure can be lifted away from the container.
  • the second part of the skirt When fitting/refitting the closure, the second part of the skirt may firstly be swung/folded into alignment with the first part of the skirt and subsequently the closure is slid downwards until the locking means engage the curl portion and/or projection.
  • the method of fitting/refitting the closure to the container may comprise the conventional method of pressing the closure downwards e.g. by the person filling the container.
  • the closure is applicable for a lot of known containers having a curl portion, and as the closure can be fitted to such containers by use of conventional production equipment, the closure can be sold separately (not in combination with a container) to manufactures of containers. As the closure can be sold separately, the packing volume for exportation is reduced to a minimum because the closure can be stacked very close.
  • the closure may be placed on the opening of the container and subsequently the second part of the skirt is swung/folded into the locking position.
  • the present invention relates to a method according to claim 24.
  • the step of providing the skirt may comprise extruding or injection moulding the skirt.
  • Fig. 1 shows a cross-sectional view of the closure 1 and container 2 according to the invention.
  • the closure comprises a metal cover 3 and a skirt 4, which together defines the closure for the container.
  • the container comprises a curt portion with a lower edge 5, a neck portion 6 and an upper edge 7.
  • the lower edge 5 has a curved portion with a radius substantially equal to the radius of the curved rib portion 8 of the skirt.
  • the skirt comprises a first part 9 attached to the cover and a second part 10, the second part being outwardly foldable (in the direction 11) between a locking position, where the curved rib portion 8 engages the lower edge 5, and an unlocking position where the second part is folded outwards.
  • the second part is foldable around the point 15.
  • the cover comprises a compound 12 that fits tightly to the upper edge 7 of the container so as to provide a sealed closure.
  • the cover comprises an outwardly inclined wall portion 13 engageable with the internal surface 14 of the container defined by its sidewall, said wall portion and skirt defining a cavity for said curl portion of the container.
  • Fig. 2 shows a skirt with a bulb portion 16 in the upper part that is attached to the cover.
  • the bulb ensures that the skirt stays attached to the cover.
  • Fig. 5 shows the same embodiment of the invention as shown in fig. 1, but wherein the second part 10 of the skirt is swung up into an unlocking position. In this position it is possible to lift the closure off the container.
  • the second part When refitting the closure to the container, the second part is firstly swung back into alignment with the first part, and the closure is then placed above the container and slid downwards until the curved rib portion 8 goes into engagement with the lower edge 5.
  • Figs. 7-8 show 3D-views of container 2 and closure 1 comprising a metal cover 3 and a skirt 4.
  • the skirt in fig. 7 comprises silts 17 extending transverse to the circumferential direction of the skirt. The slits allow for an easier folding of the second part of the skirt.
  • the form of the closure provides that the containers with the closure attached thereto can be stacked on each other.
  • Figs. 9a, 9b, 10a and 10b show a dosure 1 and container 2 according to the invention.
  • the dosure comprises a metal cover 3 and a skirt 4, which together defines the closure for the container.
  • the skirt 4 comprises a detachable part 18 and a non-detachable part 19.
  • a weakening line 20 separates the detachable part 18 and the non-detachable part 19.
  • the parts 18 and 19 may be moulded in one piece.
  • the detachable part 18 is detached from the non-detachable part 19.
  • the curved rib portion 8 (not shown) is thicker on the detachable part 18 than on the non-detachable part 19.

  • the skirt 4 comprises a detachable part 18 and a non-detachable part 19.
  • a weakening line 20 separates the parts 18 and 19.
  • a strip 21 may be pulled in the direction 22 resulting in detachment of the detachable part 18. After said removal the non-detachable part of the skirt comprises a hole 23.
  • a handle 24 may be used to remove the closure form the container.
  • a strip may be used to remove the detachable part 18 from the non-detachable part 19.
  • the handle 24 may be used to remove the closure.
