Abstract
The present invention relates to material packaging made of corrugated cardboard sheet having a polygonal cross section, comprising lateral walls, a lower plane forming the bottom of the packaging, and an opposite upper plane. It comprises at least one portion (25, 26) projecting with respect to the upper plane. The bottom (30) comprises at least one surface portion (15, 16) that is cut out over a portion of the thickness of the cardboard sheet, is compressed and in the form of a non-through hollow, referred to as a hollow portion, the shape of which matches the projecting portion, in line with the latter and arranged to fit together with the projecting portion of the packaging below.
Claims26
A material packaging made of corrugated cardboard sheet having a determined thickness, said packaging having a polygonal section, including lateral walls, a lower plane forming the bottom of the packaging, and an opposite upper plane, comprising at least one portion (25, 26;
- 97a) projecting with respect to the upper plane, characterized in that the bottom (30, 90) comprises at least one surface portion (15, 16;
- 95) that is cut over a portion of the thickness of the cardboard sheet, compressed and in the form of a non-through hollow, of complementary shape to said projecting surface portion, in line with the latter and adapted to fit together with the projecting surface portion of the packaging underneath.
A blank or set of blanks made of corrugated cardboard sheet having a determined thickness and intended to form packaging of polygonal section including lateral walls, a lower plane forming the bottom of the packaging and an opposite upper plane, characterized in that, the packaging comprising at least one portion projecting relative to the upper plane and the bottom comprising at least one compressed non-through hollow surface portion, termed a hollow portion, cut over a portion of the thickness of the cardboard sheet, of complementary shape to said projecting portion, and adapted to be fitted together with the projecting portion of the packaging underneath when it is in line with the latter, once the packaging has been formed to shape.
A device for forming packaging and/or at least one centering member of such packaging made of corrugated cardboard sheets and having a polygonal section, including lateral walls, a lower plane forming the bottom of the packaging and an opposite upper plane, said member comprising a hollow portion provided on the lower face of the bottom and a portion projecting relative to the upper plane of the packaging of complementary shape to and in line with said hollow portion, characterized in that the device includes means (67) for bringing the wall forming the bottom of the packaging into a particular position,
- in that at least one surface portion (400) of the external face of said bottom having been cut beforehand over a portion of the thickness of the cardboard sheet forming the bottom, it further includes
- at least one part (62, 63) for compressing said cut surface,
- at least one counter-pressure member (64, 65) facing said compression part,
- and pusher means adapted to compress said cut surface portion between the compression part and the counter-pressure member to form said portion in the form of a non-through hollow.
A method of forming packaging made of corrugated cardboard sheet having a polygonal section, including lateral walls, a lower plane forming the bottom of the packaging and an opposite upper plane, from at least one blank featuring a panel adapted to form said bottom,
- characterized in that the panel intended to form the bottom of the packaging is brought into a particular position,
- at least one surface portion of the external face of the bottom having been cut beforehand over a portion of the thickness of a cardboard sheet forming said bottom, said cut surface portion is compressed by exerting a counter-pressure in the opposite direction to said compression to form a surface portion in the form of a non-through hollow.
