Container for packaging use in the form of a parallelepiped made from a flat sheet

Abstract

A container in the form of an open-topped parallelepiped defined by a flat base and perpendicular thereto, two side walls and two end walls, the container being formed by folding and fixing areas of a flat base that has previously been shaped and notched by blanking. Each end of a side wall is attached flat against an end wall by only a first part of its area that is superimposed on this end wall, an L-shaped cut allowing its unattached second part to rotate with respect to the first part about the axis that separates them and with respect to a fold line that joins it to the rest of the side wall, moving from a position of coplanarity with the first part, to a position in which it is parallel to and in contact with the first part.

1 . Container ( 1 ) for packaging use in the form of an open-topped parallelepiped defined by a flat base ( 2 ) and, perpendicular to this, two side walls ( 3 ,  4 ) and two end walls ( 5 ,  6 ), the container ( 1 ) being formed by folding and fixing areas of a flat base ( 14 ) that has previously been shaped and notched by blanking, the container being characterized in that when assembled each end of a side wall ( 3 ,  4 ) is attached flat against an end wall ( 5 ,  6 ) by only a first part ( 11   p ) of its area ( 11 ) that is superimposed on this end wall, an L-shaped cut ( 8 ) allowing its unattached second part ( 11   s ) to rotate with respect to the first part ( 11   p ) about the axis (m-m) that separates them and with respect to a fold line (n-n) that joins it to the rest of the side wall ( 3 ,  4 ), moving from a position of coplanarity with the said first part ( 11   p ) when the side wall ( 3 ,  4 ) is folded onto the flat base ( 2 ), to a position in which it is parallel to and in contact with the first part ( 11   p ) when both the side wall and the end wall are perpendicular to the flat base ( 2 ) following rotation through 90°.  
     
     
         2 . Container according to  claim 1 , characterized in that the ends of each side wall ( 3 ,  4 ) are stuck to an end wall ( 5 ,  6 ) via an area ( 11   p ) placed against it and comprising a right-angled trapezium ( 7 ), against the minor base (R) of which lies a rectangle ( 9 ) separated from the rest of the side wall by an L-shaped cut ( 8 ) having one side (S) which, when the side wall is folded onto the flat base ( 2 ), is superimposed on the fold line (z-z) along which the latter is joined to an end wall ( 5 ).  
     
     
         3 . Container according to  claim 1 , in which that area of the flat sheet ( 14 ) which forms an end wall ( 5 ,  6 ) has a height (H) equal to at least twice the height (h) of the side walls ( 3 ,  4 ), and can be folded in half along a fold line (t-t) in such a way that one ( 5   m ) of its two halves ( 5   m ,  5   n ), when rotated through 180° with respect to the said fold line (t-t), is superimposed on the other half ( 5   n ) on the inside of the container ( 1 ), while contained between and parallel with the said two halves ( 5   m ,  5   n ) is the said second part ( 11   s ) of the area ( 11 ) of both ends of the side walls ( 3 ,  4 ) which join the end wall when the second part ( 11   s ) is placed in contact with and parallel to the said first part ( 11   p ).  
     
     
         4 . Container according to  claim 3 , characterized in that it is provided with means ( 10   i ,  13   i ) capable of attaching the free edge ( 5   b ) of that area of the flat sheet ( 14 ) which forms each end wall ( 5 ,  6 ) to the flat base ( 2 ) of the container when this area is folded in half along the said fold line (t-t).  
     
     
         5 . Container according to  claim 4 , in which the said means capable of attaching the said free edge ( 5   b ) consist of a number of teeth ( 13   i ) formed on this edge and an equivalent number of slots ( 10   i ) complementary to these teeth and formed on the flat base ( 2 ), into which the said teeth ( 13   i ) are inserted.  
     
     
         6 . Container according to  claim 2 , in which that area of the flat sheet ( 14 ) which forms an end wall ( 5 ,  6 ) has a height (H) equal to at least twice the height (h) of the side walls ( 3 ,  4 ), and can be folded in half along a fold line (t-t) in such a way that one ( 5   m ) of its two halves ( 5   m ,  5   n ), when rotated through 180° with respect to the said fold line (t-t), is superimposed on the other half ( 5   n ) on the inside of the container ( 1 ), while contained between and parallel with the said two halves ( 5   m ,  5   n ) is the said second part ( 11   s ) of the area ( 11 ) of both ends of the side walls ( 3 ,  4 ) which join the end wall when the second part ( 11   s ) is placed in contact with and parallel to the said first part ( 11   p ).
