FR2824810A1 - Pre-folded and glued carton for hamburgers has side walls folded and partially glued to front and rear walls - Google Patents

Abstract

The carton (1) is made from a single panel of cut-out card, folded and glued to form a base (3) and a lid (4) with side (32, 33; 42, 43) and end (34, 44; 35, 45) walls. The side walls are folded and partially glued by adhesion zones (38, 48; 39, 49) on their ends to the front and rear end walls. The carton is closed after filling by inserting a tongue (9) on the lid into slits (8) in the base front wall.

  PACKAGING, PARTICULARLY FOR THE PACKAGING OF

  HAMBURGERS, DELIVERED PRE-FOLDED GLUED

  The present invention relates to the field of packaging, in particular intended for the packaging of hamburgers, of the type produced from a cardboard blank.

cut, folded and glued.

  The present invention relates more particularly to a package comprising a bottom part and a cover part separated by a main fold line. Said bottom part comprises a base panel framed by two side walls and said part ie of the cover comprises a cover panel also framed by two side walls. Said bottom and cover parts respectively have a rear wall linked with the main fold line and, opposite, a front wall. Said rear and front walls are separated from the base and cover panels by secondary fold lines extending

on the side walls.

  The prior art already knows packaging, intended for the packaging of hamburgers and in particular the American patent N US 4 360 147 which relates to a pull-out packaging. The major drawback of this device helps in the fact that the packaging is stacked after the packaging has been completely produced, that is to say

  after the formation of the bottom and cover shells.

  The present invention intends to remedy the drawbacks of the prior art by proposing a packaging which can be stacked before the formation of the bottom and cover shells and the production of the bottom and cover shells, that is to say the volume, takes place

very easily.

  Thus, the packaging according to the invention allows a significant saving of space during storage and the bottom shell and the lid shell making it up are very

quick to form.

  To do this, the present invention is of the type described above and it is remarkable, in its broadest sense, in that the side walls are folded and partially glued at their ends against the inside of the front walls s thanks to bonding areas before and against the interior of the rear walls

  thanks to rear bonding zones.

  The outer contours of the side walls of the bottom part are preferably substantially straight and the outer contours of the side walls of the part

  of cover are at least partially in an arc.

  The rear walls preferably have a length substantially identical to the length of the

front walls.

  The side walls of the bottom part preferably have a width less than the

  width of the side walls of the cover part.

  The rear wall of the bottom part preferably has an inwardly curved longitudinal edge and the rear wall of the cover part has

  preferably a straight longitudinal edge.

  The front walls preferably have a

  longitudinal edge curved inward.

  The bonding areas are preferably formed

of triangles.

  The present invention finds applications in particular in fast food. It allows on the one hand to save space in the storage of the packaging before use and on the other hand not to waste time during the formation or realization of the shape in three

packaging dimensions.

  The invention will be better understood using the

  description, given below for purely explanatory purposes,

  of an embodiment of the invention, with reference to the appended figures: - Figure 1 illustrates a blank allowing the packaging according to the invention to be produced; - Figure 2 illustrates a perspective view of the pre-folded packaging glued according to the invention; - Figure 3 illustrates a perspective view of the formation of the bottom and cover shells of the packaging according to the invention; and - Figure 4 illustrates a perspective view

  packaging according to the invention set in volume.

  The packaging (1) according to the invention, illustrated in FIG. 1, is a packaging, in particular intended for the packaging of hamburgers, of the type produced from a blank (2) of cut cardboard, comprising a bottom part (3) and a cover part (4) separated by a main fold line (5). Said bottom part (3) has a base panel (31) framed by two side walls (32, 33) and said cover part (4) has a cover panel (41) framed by two side walls (42, 43 ). Said bottom (3) and cover (4) parts respectively have a rear wall (34, 44) linked with the fold line

  main (5) and opposite, a front wall (35, 45).

  Said rear (34, 44) and front walls (35, 45) are separated from the base (31) and cover (41) panels by secondary fold lines (36, 37, 46, 47)

  overflowing on the side walls (32, 33, 42, 43).

  The package (1) according to the invention is characterized in that the side walls (32, 33, 42, 43) are folded and partially glued at their ends against the inside of the front walls s (35, 45) thanks to bonding zones before s (38, 48) and against the interior of the rear walls (34, 44) by means of rear bonding zones (39, 49). The pre-folded and glued packaging is

illustrated in figure 2.

  The packaging (1) according to the invention makes it possible to form a box having a bottom shell and a cover shell linked together by the fold line.

main (5).

  When folding the packaging along the main folding line (5), the side walls (32, 33) and (42, 43) automatically straighten in a position where they are substantially perpendicular respectively to the bottom panels (31) and cover (41), causing in this movement illustrated in FIG. 3 the formation of the shells of

bottom and cover.

  The packaging thus formed and set in volume is

illustrated in figure 4.

  The bonding of the side walls (32, 33, 42, 43) is carried out after the folding of the side walls (32, 33,

  42, 43) along the longitudinal fold lines (6).

  The packaging (1) has a closure system (7) composed of a slot (8) formed in the front wall (35, 45) respectively of the bottom part (3) or the cover part (4) and an appendage (9) formed respectively in the front wall (45, 35) respectively

  the cover part (4) or the bottom part (3).

  The slot (8) partially opens out on the outer edge of the part in which it is fitted and the appendix (9) has returns (10) capable of cooperating with the non-opening parts.

of the slot (8).

  The base panel (31) of the bottom part (3) has a width 12 substantially equal to the width of the covering panel (41) of the cover part (4) but has a length L3 substantially less than the length L4 of the panel

covering (41).

  Preferably, the outer contours of the side walls (32, 33) of the bottom part (3) are substantially straight and the outer contours of the side walls (42, 43) of the cover part (4) are at least partially in arc of a circle, in order to promote cooperation between the side walls (42, 43) of the cover part (4) and the side walls (32, 33) of the bottom part (3) during the formation of the box through

  folding along the main folding line (5).

  Also preferably, the rear walls (34, 44) have a length L1 substantially identical to the length of the front walls (35, 45), but the side walls (32, 33) of the bottom part (3) have a width 13 less than the width 14 of

  side walls (42, 43) of the cover part (4).

  In addition, the rear wall (34) of the bottom part (3) has an outer edge B3 which is preferably curved towards the inside of the bottom part (3), while the rear wall (44) of the cover part (4) has an outer edge B4 which is

preferably right.

  Preferably, the front walls s (35, 45) have a longitudinal edge B5 curved inwards. Also preferably, the areas of

  collage (38, 39, 48, 49) are formed from triangles.

  The invention is described in the foregoing by way of example. IT is understood that the person skilled in the art is able to carry out different variants of the invention without going beyond the scope of the patent.
