Description

BACKGROUND OF THE INVENTION This invention relates to containers for transport and more particularly to containers for the transport of rolls of laminated material or flexible film, which are reusable. The transport of rolls of laminated material or flexible film has hitherto been carried out using corrugated cardboard boxes. The material is wound around a cylindrical center and is supported at its ends by end plates. A representative container of this type is shown in U.S. Patent No. 3,719,539. Such cardboard containers, however, can easily be damaged during transport by crushing, thereby damaging the film contained therein. Stacking multiple containers is usually difficult, due to the load restrictions on the cardboard. Also, cardboard boxes are not reusable and can not be returned. The non-reusable packaging in quantity presents a waste disposal problem and is ecologically undesirable. Large rolls of pressure sensitive material present additional difficulties. Such rolls are typically stored and transported in containers of REF: 25591 wood, in which the roll is fixed by means of devices similar to shaped polystyrene wedges or comparable non-flexible material. Such wooden containers are also not reusable and consequently they are expensive and add to the problem of waste disposal. An object of this invention is to provide a container assembly for rigid transport for rolls of laminated material or flexible film. A further object of this invention is to provide a foldable, stackable, reusable cardboard box for rolls of laminated material or flexible film. Another object is to prevent the rolls of material from being damaged during transport. The above and the other objects of the invention will be clearer from the reading of the specification in conjunction with an examination of the drawings.

DETAILED DESCRIPTION OF THE INVENTION FIGURE 1 is a perspective view of the box 100 of the present invention with a partial cut. The box 100 comprises a frame, consisting of a front wall 6, an opposite rear wall 7, opposite side walls 4 and 5, upper panels 3 and 3a, lower support 15 and solid support 60. In each corner of this frame rectangular is a vertically projecting arm 8. Near the top of each arm that is projected vertically is a horizontal arm 9, which connects each of the arms projecting vertically respective. The lat bar # # 20 is attached to the arms projecting vertically 8 and runs along the side walls 4 and 5. The box 100 can be constructed of any suitable material, such as metal, wood, plastic high density or composite materials. Preferably the frame is made of metals, such as galvanized steel, cast steel, aluminum or other suitable alloys. Preferably, a material whose characteristics allow the stacking of multiple boxes is selected. The individual components of the box are connected to each other by methods known in the art, such as welding or bolting. Projecting from the lateral bar 20 are the legs 10, which are interconnected to the horizontal bar 21, which is attached to the vertically projecting part of the frame 8. The legs 10 are positioned so that the openings 11 are available to manipulate the box by means of a forklift or other handling devices. The side walls 4 and 5 can be constructed from a single panel. Alternatively, the walls 4 and 5 may consist of one or more superimposed or adjacent panels. Such panels can be constructed of any suitable material, such as aluminum, steel, plastics or wood. The vertical frame parts 8 comprise two parts, the lower section 23 and the upper section 24. The extension means 41, FIG. 5, have a cut slot 48 near or at the midpoint of the length of the extension means 41. The component 24 can be raised vertically away from the lower component 23 and placed in an obliquely open position. The bolt 47 is fixed in the extension means 41 at or near the lower section of the extension means 41. When the upper section 24 is vertically raised and placed in the oblique position, the bolt 47 moves within the cavity 49, generally elliptical in shape, and is engaged by the edges of the cavity 49 at or near the upper edges of the cavity 49 to provide stability to the upper section 24 in the open position. Box 100 may collapse when empty. The front wall 6 and the rear wall 7 are connected to a lower support 15 by means of hinges 16 as shown in FIGURE 3. With the upper section 24 the oblique open position, the side walls 4 and 5 can be placed outwardly. parallel to the lower support 15 and stored below the solid support means 60. FIGURE 4 shows the side wall 4 in the collapsed position. The upper section 24 can also be bent inwardly to collapse the box 100 for storage and transportation when empty. The extension means 41 rise vertically and rotate around the bolt 47 inwardly so that the vertical portions 24 will be horizontal above the solid support means 60.

The upper panels 3 and 3a, FIG. 1, are formed to be suspended from the front wall 6 and the rear wall 7 to be supported by the upper edge of such walls when the upper panels 3 and 3a are in the closed position. Each top panel 3, 3a is attached to a corresponding side wall by means of hinges, not shown, or other suitable means, to allow such panels 3, 3a to be opened from the closed position. The chain 50a, FIGURE 5, can be tied when the upper panels 3, 3a are closed in a horizontal position to prevent such panels from opening during transport and handling. The solid support means 60, FIGURE 5, hold the roll contained within the box 100. The solid support means 60 is comprised of a suitable solid material which will support the roll weight without deformation, such as but not limited to metals , alloys of metals, hardened plastics and solid foams. On top of the solid support plate 60 is the transport plate 61 with a layer of foam 62 in a position of contact with the roll placed therein. The transport plate 61 is connected to the side bar 63, which runs along the side bar 20. The box 100 can also be stacked. The opening 70, FIGURE 1, is the cross section of the vertical upper section 24, which fits into the opening of the cross section 72 of a corresponding lower cross-section opening of another box to allow the stacking of completely open boxes. The end plate 72 attached to the lower end of the lower vertical section 23 stabilizes the section 23 when it is placed over the opening 70 of a second box placed below it.

It is noted that in relation to this date, the best method known by the applicant to carry out the aforementioned invention, is the conventional one for the manufacture of the objects that it refers. Having described the invention as above, property is claimed as contained in the following:
