Abstract
An unfolding box the base of which is quadrilateral in shape, and its sides are extended by two main flaps and two secondary flaps, respectively associated with two opposite sides by a folding line, the flaps have no folds and their width increases from the base side, their edge being convex, to decrease again towards the flap ends. The main flaps are extended by a blocking and gripping strip, the secondary flaps are curved against the edges of the main flaps bearing against them.
Claims8
Unfolding box for pastries, cakes, or the like, enabling such products to be placed in and removed from the box when the latter is at least partly unfolded flat, said box comprising:
- a base;
- two main flaps;
- two secondary flaps;
- said base bordered on each side by said flaps which, when joined together, form the peripheral shape and the upper part of the box while also constituting a gripping means, the whole box being cut out in one single piece from a cardboard blank or blank of similar material;
- said base quadrilateral in shape;
- the sides of the base connected to said two main flaps and said two secondary flaps associated respectively with two opposite sides of said base by a fold line;
- said main flaps extended by a locking and tripping strip joined to said main flaps by a fold line;
- said secondary flaps having a longitudinal slit in their end to receive said strips of said main flaps when said main flaps are joined by their strips;
- said main and secondary flaps having no fold and their width increasing from a respective side of said base, their flap edge having a convex shape, and then decreasing towards the flap end;
- and
- said secondary flaps curved against the edges of said main flaps and bear against said main flaps and engage via said slit with said strips.
An unfolding box for pastries, cakes, or the like, enabling such products to be placed in and removed from the box when the latter is at least partly unfolded flat, said box comprising a base bordered on each side by flaps which, when joined together, form the peripheral shape and the upper part of the box while also constituting a gripping means, the whole being cut out in one single piece from a cardboard blank or blank of similar material, and wherein:
- the base (1) is quadrilateral in shape;
- the sides of the base are extended by two main flaps (2, 3) and two secondary flaps (4, 5) associated respectively with two opposite sides (6, 7 and 8, 9) of the base (1) by a fold line;
- the main flaps (2, 3) are extended by a locking and tripping strip (10, 11) joined to the flaps (2, 3) by a fold line (12, 13);
- the secondary flaps (4, 5) are provided with a longitudinal slit (14, 15) in their end (42, 52) to receive the strips (10, 11) of the main flaps (2, 3) when the latter are joined by their strips (10, 11), characterized in that;
- the flaps (2, 3, 4, 5) have no fold and their width (b, b1) increases from the side (a, a1, 6, 7, 8, 9) of the base (1), their edge (21, 31, 41, 51) having a convex shape, to decrease again towards the end (22, 32, 2, 52);
- and
- the secondary flaps (4, 5) are curved against the edges (41, 51) of the main flaps (4, 5) and bear against the latter and engage via their slit (14, 15) with the strips (10, 11).
