ABSTRACT:
CROSS REFERENCE TO RELATED APPLICATIONS
This application is a national stage of PCT/GR97/00024 filed Jun. 30, 1997 and based upon Greek national application 96 01 00223 filed Jul. 1, 1996 under the International Convention.
FIELD OF THE INVENTION
The invention relates to an economical carton or box which is very strong and useful for the packing and transportation of agricultural and industrial products.
BACKGROUND OF THE INVENTION
Many boxes are known for use in packing and transportation of agricultural and industrial products which are formed by a single paper blank. The blank of this paper, which is usually large, is a problem since during the production of the corrugated board it is not always possible to economically limit the waste.
Also the corrugations of the corrugated board out of which a carton or box is constructed always run in one direction so that certain sides of the box lack strength not because the quality or the paper weight are not satisfactory but due to the inappropriate orientation of the corrugations of the corrugated board.
OBJECT OF THE INVENTION
It is the object of the invention to provide an improved cardboard box. The advantage of this invention is that a carton, box or tray can be constructed from different pieces of corrugated board or solid paper that are held together with glue.
In this way the combinations in the corrugated board or solid paper productive lines become much easier since the blanks are smaller and moreover at each side of the carton box, papers with the appropriate paper or, extension can be used and to yield a very economical and strong carton box.
SUMMARY OF THE INVENTION
The cardboard box of the invention, which is useful for packing and transportation of agricultural and industrial products, is made up of a number of blanks or pieces including a base, longitudinal walls connected to the base along the longitudinal base thereof and either in one piece with the base or as separate pieces, and end walls connected to the base at end edges thereof. The end walls and the base are glued together for extensions on the end walls have sides which can be followed inwardly to form columns of the box, at the corners betweens these side walls and the longitudinal walls. The longitudinal walls have extensions which extend around and are glued to the outer surfaces of the end walls at these columns. Projections on the end walls and slots formed in the base enable stacks of boxes to be aligned with the projections of one of the boxes engaging in the slots of another box.
