This invention relates to a container for containing and transporting objects and refers particularly, though not exclusively, to a disposable container for storing, and transporting objects. The use of such a container is particularly relevant, though not exclusively so, for heavy loads that require the use of forklifts to be transported.
Boxes that transport or courier companies provide for their clients' use are usually in sizes conforming to industry standards. Boxes of different sizes are usually manufactured to meet the needs of different clients. It is essential that the companies keep track of the available stocks of a box of a particular size in order to not have a surplus or a shortage of a particular box size.
The size of the boxes usually determines the load limit allowable in a particular box. Boxes with contents weighing greater than 50 kg will generally be too heavy for package handlers to lift. As such, many of the larger boxes require the use of forklifts for movement from one place to another. Currently, the boxes need to be placed on pallets to be moved about. Generally, there are no matching of packages to pallets. Also, cardboard boxes are used as they can be stored in a folded condition. Cardboard boxes are generally not suitable for heavy loads. Furthermore, pallets are generally made of timber. Timber pallets cause problems when being moved across international borders due to possible pest migration.
In accordance with a first aspect, there is provided a container comprising at least three sidewalls with corners therebetween and having an open base, and an open top. The sidewalls define an internal space for storage of at least one item. The sidewalls are foldable about the corners for ease of storage. A cover is provided to cover the open top and the internal space. Also included is a pallet onto which the sidewalls can be placed. The sidewalls each have at least one perforated line to enable the height of the sidewalls to be varied.
The sidewalls may be made of a material selected from: cardboard, treated cardboard and a plastics material. Preferably, the material is weather-resistant.
The at least one perforated line may be parallel to an edge of the sidewalls for folding along the at least one perforated line, or for being sheared along the at least one perforated line, to vary the height of the sidewalls.
The pallet may have a top, the top being planar and solid, and being of length and width slightly greater than the corresponding dimensions of the open base. A gap may be formed between an outer edge of the at least three sidewalls and a peripheral edge of the top of the pallet. The open base may be for enabling of the at least one item to be placed directly on the pallet.
The cover may be shaped to conform with the storage space defined by the sidewalls and may comprise a cover top and cover sides, the cover being adapted to removably cover the open top, and to locate on an outer surface of each of the at least three sidewalls in the manner of a snug fit.
The pallet may be formed of a material selected from: cardboard, plastics and treated cardboard. The material may be weather-resistant.
The sidewalls and the pallet may combine to form an open-top box; and the top of the pallet may form a solid base for the sidewalls. The open-top box may be closed by the cover.
In order that the invention may be better understood and readily put into practical effect, there shall now be described by way of non-limitative example only preferred embodiments of the present invention, the description being in reference to the accompanying illustrative drawings in which:
Referring to
The container 20 has four integral and mutually perpendicular sidewalls 24.
The container 20 may also have a cover 38 which is placed over open top 46 and around a top rim 44 of the sidewalls 24 and covers the contents placed in the storage area. The cover 38 has a top 36 of the same shape as the open top 46. The cover 38 also has sides 36. The cover 38 may be formed from a single cardboard blank and is preferably dimensioned so that sides 36 pass over the outer surface of each of the sidewalls 24 in the manner of a snug fit. The cover 38 is preferably a relatively tight fit over sidewalls 24 but is readily removed from and inserted onto sidewalls 24.
The sidewalls 24 have an open base 22. As there is no integral top or cover to container 20, the sidewalls 24 maybe easily folded for storage by being folded about corners 28.
Each sidewall 24 may have at least one perforated line 26 running parallel to an edge 27 at the base 22. In
When a perforated line is sheared, cuts may be made down each of the corners 28 to a preferred line of perforation such as, for example the third perforated line 32, the sidewall 24 is then sheared along the perforated line 32 on each sidewall 24. The height of the container 20 is then lowered to that of the third perforated line 32. Alternatively, each sidewall 24 may be folded about the perpendicular line into the storage area defined by the sidewalls 24 to strengthen each sidewall 24.
The base 22 is open so that the sidewalls 24 may be placed on pallet 40 with the outer edge of sidewalls 24 (indicated by line 52 on
Top 42 is of the same shape as base 22. The pallet 40 has rails 48 with gaps 50 to allow the container 20 to be lifted by forklifts without being placed on a separate pallet. The pallet 40 may also be formed from cardboard and preferably is weather resistant.
In this way sidewalls 24 may be placed on top 42 of pallet 40, and product to be transported placed inside the sidewalls 24. The height of sidewalls 24 may then be varied using one of the perforated lines 26, 30, 32 (or none of them) and cover 38 placed over sidewalls 24. Straps or the like (not shown) may then be used to secure the assembly. Alternatively, the products to be transported may be placed on pallet 40, and sidewalls 24 placed over them. By having the product to be transported directly on top 42 of pallet 40, the risk of slippage during transport is reduced. Also, as sidewalls 24 have no base, there is no risk of container 20 being lifted and the heavy contents falling through its base and being damaged. By being having a pallet, there is a clear indication to workers that a forklift is to be used and manual handling is not to be performed. If sidewalls 24 had a base (thereby forming a box), there may be a tendency for workers to attempt manual lifting. This may be quite dangerous.
The container 20 may be able to carry varying loads depending on the height of sidewalls 24 and the load capacity of the pallet 40. The higher the sidewalls 24, the greater the possible load rating of the container 20.
Whilst there has been described in the foregoing description preferred embodiments of the present invention, it will be understood by those skilled in the technology concerned that many variations or modifications may be made to details of design or construction without departing from the present invention.
