Transport and storage container
A storage and transport container, in an unassembled state, is composed of a single-piece container blank having a bottom, foldable side and end walls and four corner flaps foldable inwardly at the side walls or the end walls. Respective turnover rims are integrally formed on the side walls and the end walls so that when the turnover rims are folded over, a stacking profile having a hook rim can be attached over the same. Four corner pieces are provided, wherein each corner piece has a base body having an upper stacking rim. Two insertion profiles are integrally formed on the base body, each having an angled profile section at the front end. The angled profile section positively fits in a respective profile recess of the side walls and the end walls. The stacking profiles extend over the insertion profiles flush against the stacking rim.
1. An unassembled transport and storage container which is stackable when assembled, comprising:
a foldable container blank having a bottom, two side walls each foldable about a respective first folding line, two end walls each foldable about a respective second folding line, the side walls and the end walls being of a predetermined same thickness, four corner flaps each foldable inwardly at a respective one of the side walls or the end walls about a respective third folding line, a respective turnover rim at a top edge of each of the side walls and end walls, on each of the side walls and end walls a respective score parallel to the top edge of the side wall or the end wall, and each of the turnover rims being configured to be folded outwardly about a respective one of the scores and against the respective side wall or end wall at the top edge of which the turnover rim is located to form a rim thickness twice the predetermined same thickness of the side walls and the end walls;
stacking profiles each configured to be attached over a respective one of the turnover rims of the side walls and the end walls and comprising in transverse cross-section, an inner leg and an outer leg, the inner and outer legs connected by connecting structure only at their proximal ends and otherwise spaced from each other to define a space configured to receive a respective one of said turnover rims when said turnover rim has been outwardly folded and a hook rim integrally formed on an inner side of the outer leg and configured to be latched over a longitudinal edge of a respective one of the outwardly folded turnover rims, and an stacking rim integrally formed on and surmounting the stacking profile connecting structure;
further comprising corner pieces configured to be received between ends of adjacent pairs of the stacking profiles, wherein
each corner piece comprises a base body having a stacking rim surmounting the base body and configured to align with the stacking rims of the stacking profiles;
two insertion profiles are integrally formed on the base body perpendicular to each other and each of the insertion profiles has an angled profile section at a distal end thereof, thickness of each of the insertion profiles, in a direction perpendicular to the plane of the respective side wall or end wall, other than at the angled profile section thereof being same as the wall thickness;
a respective profile recess is formed in each of the side walls and end walls, each of the angled profile sections is of such width and length in a plane parallel to a plane of the respective side wall or end wall in which the respective profile recess is formed so that each of the respective angled profile sections forms a positive fit with the respective profile recess of the respective one the side walls and the end walls and each of the angled sections is of a thickness, in a direction perpendicular to the plane of the respective side wall or end wall, which is twice the wall thickness; and
the stacking profiles are configured to extend over the insertion profiles flush against the stacking rims of the corner pieces.
2. The unassembled transport and storage container according to claim 1 , further comprising screw connections configured to connect the stacking profiles to the insertion profiles.
3. The unassembled transport and storage container according to claim 1 , further comprising a respective molded body formed on each of two end faces of the stacking rim of each of the base bodies, wherein the end faces are at a right angle relative to each other, and corresponding openings in the stacking rims of the stacking profiles, each of the openings configured to engage a respective one of the molded bodies and thereby secure the stacking profiles to the corner pieces.
4. The unassembled transport and storage container according to claim 1 , wherein the container blank is comprised of plastic structured-core panels.
5. The unassembled transport and storage container according to claim 1 , wherein each of the corner pieces is an injection-molded plastic part.
6. The unassembled transport and storage container according to claim 1 , wherein the stacking profile is a continuously cast plastic part.
7. The unassembled transport and storage container according to claim 1 , wherein the corner flaps are configured to be fastened to the end walls when the container is assembled.
8. The unassembled transport and storage container according to claim 1 , wherein each of the corner pieces and stacking profiles has the same peripheral outer shape.
9. The unassembled transport and storage container according to claim 1 , wherein a downward extension is formed at a corner of the base body of each of the corner pieces and is configured so as to cover a gap.
10. A transport and storage container produced by assembling the unassembled transport and storage container of claim 1 .
11. The unassembled transport and storage container according to claim 1 , wherein said width and length of the angled profile is same as a width and length of the profile recess.
