Abstract

A container made of cardboard or a similar material is designed as a packaging for objects such as books, records and other solid objects. The container is formed by a cut flank that is folded in order to define panels that include a base for receiving objects, side leaves that are folded back above objects that are disposed on the base, two small cross surfaces and a closing flap. The cut flank is made from a planar blank that is formed from two parallel rectangular parts having two terminating cross edges and two longitudinal edges. One part is held against the other using a lip in the shape of an isosceles triangle. One side of the triangle is cut and the other side and the base are formed by a fold line. The fold line with the base is located at a longitudinal edge that is common to both parts, over a short longitudinal distance adjacent to a single panel. The first of the two rectangular parts has an end panel that has a defined triangular flap in the contour of the second part. The length of the second part is such that the two cross edges thereof are substantially offset in relation to the cross edges of the first part. The second part is superposed in front of the first part to form a T.

Dependent claims

A container for packaging solid objects, said container being formed from a cutout sheet that is foldable from a first position to a second position to define said container, said container comprising:

a base for receiving the objects;
a pair of lateral flaps connected to the base, said lateral flaps are foldable down over the objects disposed on the base;
and
a closure tongue connected to the base and foldable over the lateral flaps,
said sheet being a flat blank comprising two parallel rectangular portions each having two transverse end edges and two longitudinal edges,
said two rectangular portions are connected to each other by a truncated triangular tongue having a first side being cut, a second side and a base of the truncated triangular tongue are each formed by a fold line, the fold line of the base being at a first one of each of the two longitudinal edges, common to the two rectangular portions, said common longitudinal edge being shorter than a length of the two rectangular portions,
the first rectangular portion having an end panel connected to the truncated triangular tongue, the truncated triangular tongue being defined in a contour of a second of the two rectangular portions, said second rectangular portion having a length such that the two transverse end edges of the second rectangular portion are substantially offset relative to the two transverse edges of the first rectangular portion, in the first position,
the second rectangular portion is folded flat against the end panel to extend transversely to the first rectangular portion, in the second position,
the base of the container being formed by superposing a central region of the second rectangular portion and the end panel of the first rectangular portion, and
the end panel of the first rectangular portion and the central region of the second rectangular portion having means for securing to each other, in said second position.

A container formed from a cutout sheet is foldable from a first position to a second position to define said container, said container comprising:

a base for reception of objects,
a pair of lateral flaps extending outwards of said base that are foldable down from above over the objects disposed on the base,
a closure tongue connected to said base, and
an intermediate surface panel between said base and said closure tongue, wherein
said lateral flaps are folded parallel to one another after partial folding of the sheet, said lateral flaps being perpendicular to the base such that access to the base will be free for emplacement of the objects on the base, in said second position, and wherein
said lateral flaps have means for securing to said intermediate surface panel, such that the lateral flaps and the intermediate surface panel are temporarily secured together in the second position after partial folding, before emplacement of the objects on the base and until closure of the container.
