Description
(54) CLOSABLE CONTAINER
(71) We, CURVER B.V., a Netherlands
Limited Liability Company of P.O. Box 25,
Rijen, the Netherlands, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:- This invention relates to a closeable container with a closing cover and a bail pivotally connected by means of studs to the wall of the container, and comprising means for locking the cover in the closed position.
Closable containers of this type are used for instance as cooler boxes for keeping cool drinks and foods that have to be transported for use at camping sites, picnic spots and the like. The containers must then be so closed as to prevent accidental opening as a result of shaking during transportation, for instance in the boot of a motorcar. Known containers are constructed so that they can be opened only after the bail has been placed in a specific position.
A disadvantage of such known containers is that the bail can, without any appreciabIe resistance having to be overcome, be brought into the position in which the cover can be removed. This results in the possibility of the container being inadvertently opened by for instance children at play. Also it is necessary to check, after the container has been closed, that the bail is back in the locking position. The provision of a separate locking member results in a complication in design, and if the locking member is a separate element, a complication in assembly, resulting in an increase in cost, particularly in the manufacture of mass-produced articles.
The invention provides a closeable container wherein such disadvantages are avoided.
The invention provides a closable container with a closing cover and a bail pivotally connected by means of studs to the wall of the container, characterized in that the said studs protrude inwardly through the wall of the container so that when the said cover is in a closed position on the container they project into corresponding depressions provided in the cover thereby to lock the cover on the container, the said bail being constructed of resilient material whereby it can be moved outwards to a position whereby at least one of the said studs no longer projects into the corresponding depression in the cover thereby enabling the cover to be removed.
The container according to the invention is simpler in design than known containers in that the studs of the bail also serve as locking members for the cover, thereby dispensing with the need for separate locking members or locking members connected to the bail.
The ends of the studs and the depressions in the cover thus provide a snap-action connection which maintains the cover in the closed position. Preferably the ends of the studs have a rounded or tapered configuration, in which instance a handhold may be provided for removal of the cover against the resilience of the bail. This handhold may be a recess adjacent the upper edge of the container or adjacent the lower edge of the cover.
The container is closed by pressing the cover with some force on the container so that the stud ends snap into the depressions.
Opening of the container is effected by so far lifting the cover on one side that the stud end is forced out of the depression on that side owing to the resilience of the bail, after which the cover can be removed. The recess in the upper edge of the container or the lower edge of the cover provides a good grip on the cover in lifting. The force required for opening depends on the rigidity of the bail, the depth of insertion of the studs in the depressions and the taper (when present) of the stud ends.
In a preferred embodiment of the invention, the stud ends are tapered to co-operate with a correspondingly tapered surface of the depressions in the cover in such a manner that the cover in the closed position is forceably held down on the upper edge of the container.
The resilience of the bail will then also contribute to ensuring a good seal between the cover and the upper edge of the container.
Preferably the underside of the cover contacting the studs when the cover is put into place, is rounded or bevelled.
Also preferably the studs have stops preventing their being completely pulled out of the wall of the container. If the container is a double-walled one, e.g. a - cooler box, the studs are provided with stops which after the bail has been put ili-rpIace -come between the inner and outer walls and in co-operation with the outer wall prevent the bail coming loose.
The invention is hereinafter particularly described and illustrated in the accompanying drawings of which
Figure 1 is a side view of an oblong-shaped cooler box according to the invention;
Figure 2 is a front view of the cooler box of Figure 1 Figure 3 is a large-scale- sectional view of the connection of the bail to the cooler box cover in the closed position; and
Figure 4 is a sectional view of this connection during removal or placement of the cover.
Referring to the drawings, a cooler box 1, oblong in top view, comprises an outer box 2 and an inner box 3. The upper edge 4 of the inner box is folded outwards and at 5 joins the upper edge of the outer box. The inner and outer boxes may be connected to each other in a way not shown in the drawing, e.g.
by a snap-action connection. The space 6 between the inner and outer boxes may be filled with a heat-insulation material, e.g. a foamed plastics material. The boxes are made of a suitabIe plastics material e.g. highdensity polyethylene, polypropylene or polystyrene.
At the top of the cooler box a bail 7 is fitted, provided with studs 8 which, in the narrow sides of the oblong cooler box, protrude through openings 9 and 10 in the folded upper edge of the inner box and whose rounded ends 11 project into the cooler box.
The bails are also made of a plastics material, e.g. a polystyrene of high impact strength, so that they have sufficient elasticity to allow of being bent open so far that during assembly their studs can be inserted into the openings 9 and 10. The studs have stops 12 which slightly project outside the diameter of the opening 9. Elastic deformation of the plastic allows the stops on the studs to be pushed through the openings 9 when the bail is being fitted. To facilitate this fitting, the stops are bevelled towards the stud ends. On the other side the stops are straight, so that the possibility of the bail being pulled out of the openings 9 when the cooler box is in use is obviated.
The cooler box can be closed by a rectangular cover 13. The short sides of the part of the cover inserted into the cooler box have depressions 14 into which the ends 11
of the studs 8 project when the cover is in the
closed position. The depressions are rounded
to correspond with the stud ends 11, and are
so positioned that when the cover has been
put in place the studs exert a downward
force on the cover as a result of the resilience
of the- bail, which presses the studs inwards.
The result is that the upper edge 15 of the
cover is pressed on the upper edge 4 of the
inner box, so that a good seal and, conse ,quently, - god insulation -is -obtained. The
cover can be made by blow moulding of a
thermoplastics material e.g. polyethylene,
polypropylene or polystyrene.
The upper edge,,. 4 of the inner box is
provided with a recess 16, which makes it possible to place the fingers under the cover
in order that this may be removed from the
container. The cover is thus lifted on one side,
as shown in Figure 4, so that the stud on one
side of the container, is forced out, against the resilience of the bail, by the part of the
cover under the recess 14, This can be facili tated by pulling out, with the free hand, the
bail on the side on which the cover is lifted.
The cover will now on this side come clear
of the stud, after which it can easily be re
moved entirely. The cover can be fitted or
removed irrespective of the position of the
bail. Closing is effected by pressing the cover
onto the cooler box, so that the studs first move outwards and next snap into the re
cesses. To facilitate this, the underside of the cover is rounded or bevelled at 17.
Alternative constructions may be provided.
For instance the depressions 14 may have the form of a groove running the length of the
short side of the cover. Also the recess 16 may be either local or run the length of the
short side and/or long side of the cover or the upper edge of the container. The container
and cover may be of shape other than rectangular e.g. a circular or square shape as viewed from the top.
