Description

(54) BOX COMPOSED OF PRESSED MATERIALS FOR SHIPPING FRUITS, VEGETABLES AND THE LIKE (71) We, FORMWOOD LIMITED, of Tufthorn Avenue, Coleford, Gloucestershire GL16 8PR, a British Company, 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 box of pressed materials for shipping fruits, vegetables and the like, which is intended for one use only and is therefore disposable and is adapted for storage in piles.
Disposable boxes have found increasing use as one-time packaging for shipping fruits, vegetables, and the like. These boxes are then destroyed at the point of destination. It is important in these cases that the cost of the packaging constitute as low a friction of the packed goods as possible and that their destruction does not interfere with the environment and does not result in large amounts of waste. This is for instance accomplished by burning the material when they reach their final destination.
In spite of these requirements the boxes must have a strength that the goods which usually are of a delicate nature are adequately protected. The box must furthermore not absorb humidity either from its contents or from the exterior atmosphere since this would affect the strength of the packaging material which in the case may disintegrate during shipment and may cause loss of the contents.
Disposable boxes are known which are made of single thin panels of which each is connected with the next panel and which when opened up are in one plane and are made in single pieces from a mixture of lignocellulose chips or fibres and a curable binding agent.
The box of the prior art has proved quite useful for a number of applications. However, its manufacture is still too costly for some uses and the thus-formed product is therefore too expensive in a number of cases of use.
The object of the present invention therefore is a box which can be made in an inexpensive way from single parts without affecting the quality of the product. Besides, the individual boxes must be adapted to be arranged in piles so that they make the best use of available space during shipment and reduce the transportation costs. It is also necessary that they can be assembled in a simple way at the place where they are used.
The box moreover must be form stable to permit stapling in piles of large numbers of boxes. This involves the further requirement that the boxes must be formed so that when stored in piles upon each other they are not subject to shifting.
According to the invention, there is provided a box comprising individual pressed parts and suited for the shipping of fruits, vegetables etc., and adapted for stacking in nesting relationship on top of a further said box, said box comprising two pairs of abutting side panels held together by clamping means and a bottom wall, the lower edge of each panel having an inwardly offset portion adjacent each end thereof which forms an inwardly offset foot in conjunction with the offset portion of an abutting panel, each end of each panel being deformed inwardly adjacent its upright edge to provide an inwardly directed rib having a face which abuts with the corresponding face on the rib of an adjacent panel to form a projecting corner section whose upper end is located below the upper corners of the box and provides an enlarged base to receive the foot of another box placed on top thereof, and the foot being receivable within the confines of the upper edges of an underlying box in a stack.
In a preferred embodiment, the lower edge of each panel is turned inwardly to form a shoulder to support the bottom wall. Alternatively, a channel may be provided extending parallel to the bottom edge of each panel.
Preferably the box panels are made from a press-mass of a mixture of lignocellulose fibres and a cured binding agent.
The bottom wall may be flat or it can have upturned and then outwardly directed edge portions which form a box shaped receiving space therein.
Conveniently, each panel may have a bent portion which forms a bracing element extending parallel to the upper edge of the panel and/ or a bent portion forming a stiffening strip disposed parallel to and spaced from its inwardly turned lower edge, said bent portion and lower edge forming a channel to receive the bottom wall of the assembled box.
Desirably, slots are provided in at least one pair of said panels at their adjoining corner portion for receiving fastening elements.
In order that the invention may be more readily understood, reference is made to the accompanying drawings which illustrate diagrammatically and by way of example embodiments thereof, and in which Figure 1 shows the box of the invention in a perspective view together with a part view of another box of the same type, the two boxes being piled upon each other; Figure 2 is an enlarged longitudinal section through a part of the adjoining portions of the two boxes; and Figure 3 is a partial longitudinal section through part of the box illustrating another embodiment for receiving the bottom member.
Referring to Figure 1 of the drawings, the box consists of four substantially rectangular, equal panels wiuch are connected with each other at their corners, and which receive a bottom 4 of the box. The corner portions 1 of each panel are bent outwardly to improve the stiffness of the box so that it can withstand comparatively high compression stresses at the corner portions wInch will receive these stresses during piling up of the boxes. This is made possible without increasing the strength or thickness of the panels. Thus, a comparatively large number of boxes can be arranged in piles.
The lower edge of each panel has an inwardly offset portion adjacent each end thereof which forms an inwardly offset foot 3 in conjunction with the offset portion of an abutting panel, the end of each panel also being deformed inwardly adjacent its upper edge to provide a inwardly directed rib, having a face which abuts with the corresponding face on the rib of an adjacent panel to form a projecting corner section 2' whose upper end is located below the upper corners of the box and provides an enlarged base to receive the foot 3 of another box placed on top thereof, the foot being received within the confines of the upper edges of the lower box in the stack.
The upper edge of each panel is also provided with a rim 2 which is adapted to cooperate, in the stacked condition of the boxes, with the inwardly offset foot portion 3. Thus, a closed interlocking connection of the boxes is possible when arranging them in piles without danger of slipping of the boxes against each other.
The shape of the lower edge of each panel as described also permits a simple and secure form of holding for the bottom or floor 4 of the box.
A channel 6 is formed between the inwardly offset lower edge foot portion 3 and an inwardly bent portion 5 which acts as a stiffening element and extends parallel to the lower edge, into which the box bottom 4 can be placed or snapped in to provide a secure interlock.
The bottom member 4 normally is formed as a flat sheet or plate, for instance of pressed wood or fibre-board. The bottom or floor can alternatively be constituted by a member 4' to provide a box-shaped receiving space as more clearly shown in Figure 3. This embodiment is of particular advantage if the boxes are moved on conveyor lines consisting of rollers.
The box of the invention is particularly suited to be shipped in disassembled manner without requiring much space so that it is assembled only at the place of first use. In this case the individual panels of the box and the bottom are shipped in a pile and are assembled later by connecting the panels at the corners by means of metal clips 7.
From the foregoing description it will be appreciated that the box frames can be partially pre-assembled ready for final use and stored in piles by connecting three of the four corners with the wire clips 7 whereby the frame of the box which is still open at one corner portion can be placed flat on a flat support surface. The corner portions at the fourth edge are provided with slots 8 through which the metal clips or wire staples may be inserted during final assembly of the box frame.
The strength of the individual panels of the frame is further increased by the provision of a bent portion 10 which serves as a bracing member and is provided near their upper edge.
As shown in Figure 1, some of the panels may be provided at their upper edge with a cutout recess 11 which permits easy handling of the boxes during storage and removal, easy access to the interior thereof when they are stacked in a pile. These recesses also permit airing of the contents of the boxes so additional airing apertures are unnecessary.
