Description
BACKGROUND OF THE INVENTION
The invention relates to container assemblies having
containers.
The term "container" is intended to include any casing, holder or
support for goods which has a bottom wall on which the goods can
rest. The invention is thus applicable to pallets and
stillages.
It is known to produce pallets for carrying goods, wherein the
bottom of the pallet -- on which the goods are to rest -- comprises
a single layer of cardboard material, and wherein there are
provided a number of supports to space the bottom of the pallet
from the ground. The supports are a tight push-fit in holes drilled
through the single layer of cardboard, and are pushed in from the
topside of the layer.
Disadvantages of this known construction are that it would not be
rigid enough to withstand repeated handling by warehouse fork lift
trucks, and that the weight of any load not uniformly spread over
the whole pallet area would tend to separate the bottom of the
pallet from its supports.
SUMMARY OF THE INVENTION
According to the invention there is provided a container assembly
for goods, including a container, and wherein the bottom of the
container on which the goods are to rest comprises at least two
superimposed layers of material and wherein there are provided a
plurality of supports to space the bottom of the container from the
ground, each of which supports comprises a first part sandwiched
between the two layers and a second part disposed beneath the lower
of the two layers, which parts are connected by another part which
projects through an aperture in the said lower layer.
The other part may be integral with either the first part or the
second part.
The first and second parts may be foldable relatively to one
another whereby the first part may be passed through the aperture
and deflected into position between the two layers. For example,
the other part connecting the first and second parts may comprise a
hinge connection or a flexible element.
Each support may comprise a single second part to which are
connected two or more first parts passing through separate
apertures in the lower of the two layers of the bottom wall of the
container.
The container may be formed from any suitable material such as
cardboard, fibre board, wood, plastics or the like.
The container may be of the kind which is folded from a blank and
having a bottom wall made up of two or more flaps folded from
different side walls of the container so as to overlie one another,
the flaps forming the bottom wall of the container then
constituting the aforesaid layers.
Each aperture may comprise a slot formed in the lowermost layer or
layers. Preferably each slot runs parallel to an adjacent fold of
the container. Alternatively each aperture may be constituted by
the edge gap formed when the container flaps are folded to overlie
one another.
Each aforesaid second part may provide one or more apertures
vertically spaced to permit entry of the forks of a fork lift truck
laterally through said second part.
In any of the above arrangements in which a flexible element is
provided, the flexible element and the second part may be
integrally formed from a suitable material, for example a flexible
or semi-flexible plastics material.
Where more than one support is provided, the second parts of the
supports may be interconnected by spacing means outside of the
container.
The invention includes within its scope a set of components for
forming a container assembly of any of the kinds referred to above,
the set comprising a blank from which may be folded a container
having a bottom wall comprising at least two superimposed layers of
material, the flaps which are to form the lowermost layers having a
number of apertures formed therein, and a number of supports of any
of the kinds referred to above.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a plan view of a corrugated fibre board blank for forming
a container;
FIG. 2 shows the blank partially assembled into a container, two
walls being cut away for clarity; and
FIG. 3 shows to a larger scale a vertical section through the
completely assembled container.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIG. 1, a corrugated fibre board sheet blank is formed
with weakened folds extending along its surface. The folds divide
the sheet blank into four walls 51, 52, 53, 54, four base closure
flaps 55, 56, 57, 58, four top closure flaps and a fastening strip
71 adjoining one edge of the endmost wall of the blank. Two of the
base closure flaps, 56 and 58, each of which will hinge on opposed
side walls of the assembled container, are provided with elongate
slots 59, 61 running parallel to the flap folds.
For use with the container there are provided two supports, each
consisting of two wooden battens 62, 63 between which are
sandwiched two wooden blocks 64, 65. In this embodiment, the wooden
blocks are located at opposite ends of the battens and are nailed
into place. One of two thin flexible sheet metal strips 66 is
sandwiched between the topmost batten and each wooden block, and
the two strips 66, 67, have rivetted to them plywood tongues 68, 69
respectively which are sized to fit the aforementioned slots 59,
61.
As best seen in FIG. 2, the container is assembled by folding the
ends of the blank together and stapling the overlapping fastening
portion 71 to the opposite wall 51 to form a rectangular box. The
two base closure flaps 55, 57 are then folded towards one another
across the lower end of the box, and the closure flaps 56, 58
having the slots are also folded across the lower end of the box so
as to be beneath the other base closure flaps.
The plywood tongues of each support are then inserted into the
slots from beneath the base of the container so that the topmost
batten seats against the base, and are folded flat inside the
container to be sandwiched between the two sets of closure flaps
and retained in position, the flaps being pressed down on top of
the plywood tongues. The two layers formed by the flaps act as a
floor for the container, and the presence of the wooden supports --
which straddle the outermost flap join -- prevents the weight of
goods in the container from bursting open the base closure flaps.
When the container has been filled, the top closure flaps are
folded and stapled together to close the container in known
manner.
The height of the supports, and the spacing between the wooden
battens, are such that entry of the forks of a fork lift truck
beneath the container is possible, and the lower edges of the
lowermost batten are chamfered to facilitate sliding of the
container over an uneven floor.
Although two supports are used in the embodiment just described, it
will be appreciated that other embodiments could use different
numbers of support depending upon such factors as the size and
shape of the container and the weight of goods to be supported.
Further embodiments having alterations to some or all of the
features of that described above, but which remain within the scope
of the invention are also possible. For example, the slots in the
outermost base closure flaps may be dispensed with and the support
tongues inserted into the edge-gaps formed when the two sets of
base closure flaps are folded to overlie one another. In this
embodiment, the supports would span the container from edge to
edge. The tongues themselves may be located at points on the
support other than one of the outer edges -- for example, they may
be located at a central portion of the support -- and there could
be any suitable number of them. One 62 of the support battens of
the embodiment described above could be dispensed with, and in that
embodiment the two supports could be interconnected by further
battens 72 or connecting means to form a composite structure. In
such an arrangement, the positioning of the tongues on the supports
would have to be suitably matched to the spacing apart of the slots
in the blank.
Where the container is in the form of a pallet or stillage, the
side walls are usually omitted or are in the form of upturned edges
serving to reinforce the horizontal edge. Thus to form for example
a 48 .times. 40 inch pallet using three supports, the side walls of
a container blank (without top closure flaps) could be folded over
again to overlie the two sets of base closure flaps and thus form a
pallet of several thicknesses of board. The tongues of alternate
supports could then be sandwiched between different layers of board
to take the weight of goods carried by the pallet.
A simpler form of pallet embodying the invention comprises a flat
sheet corrugated board, whose two opposed comparatively narrow end
flaps are slotted as described above and then turned under the
sheet to receive the tongues of the supports.
