Description

1 TRAY FOR BAG PRODUCTS

  The present invention relates to a tray made of cardboard sheet material having a bottom formed of at least one upper flap and at least one lower flap superimposed.

  It finds a particularly important, although not exclusive, application in the field of corrugated or compact cardboard boxes containing semi-rigid sachets, for example sachets of powdered soup or dehydrated beverage, used as display racks on store shelves. .

  We already know boxes or trays open upwards for the presentation of this type of products. These have disadvantages.

  Indeed, as the bags are taken by consumers, the remaining bags fall to the front of the tray. Then comes a time when the bags are found horizontally at the bottom of the box and are no longer visible or easily seized by consumers.

  This is detrimental to the image of products that can be overlooked by the customer, resulting in lower sales and a feeling of disorder in store shelves.

  The present invention aims to overcome these disadvantages by providing a tray made of cardboard sheet material better than those previously known to the requirements of the practice including that it will allow the maintenance of the remaining bags in sufficiently attractive presentation position so that they remain visible to the consumer even when most of the bags have been removed, and this in a simple, inexpensive and easy to implement.

  For this purpose, the present invention essentially provides a board made of cardboard sheet material having a bottom formed of at least one upper flap and at least one lower flap superposed, characterized in that the lower flap is provided with minus a raised tab snapped into a corresponding opening in the upper flap to form an internal stop facing the back wall of the tray at an angle to the bottom.

  By creating intermediate stops on the bottom of the tray, directed upwardly at an acute angle, they prevent the forward sliding of the bags and whatever the number of bags remaining in the tray.

  In particular embodiments, one and / or the other of the following arrangements is also used: the plate comprises two or three internal stops centered with respect to the longitudinal walls of the plate and directed towards the wall; back of it; the tray is made from a blank comprising a series of four main components connected to each other, either directly or via intermediate flaps, via first folding lines parallel to each other, and a set of flaps comprising said upper and lower bottom forming flaps disposed on one side of said sequence of main flaps and connected thereto by second fold lines perpendicular to said first fold lines, said main flaps closed to each other constituting the main lateral walls of the body of the plate.

  the set of flaps comprises one or more lower flaps provided with an upper flap tongue, the one or two respectively connected to the corresponding by a third fold line parallel to said second fold lines, each tongue extending outwardly of said lower flap for a sufficient distance so that said tongue can snap into a corresponding opening formed by two cut half openings or opening directly near the outer edge of said upper flaps when the tray is formed; the flap assembly comprises an upper flap provided with at least one opening and a lower flap provided with at least one tongue arranged to cooperate with said opening, said tongue being connected to the lower flap by a fourth fold line perpendicular to the second fold lines.

  Advantageously, the opening or openings open on the periphery of the outer edge of said upper flap.

  The invention also proposes a blank, for the 3o construction of a tray, comprising a series of four main components connected to each other, either directly or via intermediate flaps, via first fold lines and two tabs being flap lower parallel or substantially parallel to each other, and a set of side flaps comprising at least said upper flap and at least said lower flap, said assembly being disposed on one side of said sequence of main flaps and connected thereto. ci by second fold lines perpendicular to said first fold lines and intended to form the bottom of the tray, said main shutters constituting the main lateral walls of the body of said tray when they are closed towards each other, each main lateral wall being provided with one of said flaps, characterized in that the lower flap is provided with at least one tongue arranged to be raised and snapped into a corresponding opening in the upper flap to form an internal stop having an acute angle with the bottom when the tray is formed.

  Advantageously, the blank comprises one or more lower flaps and two upper flaps, the tab or tongues being respectively connected to the corresponding lower flap by a third fold line parallel to said second fold lines, each tab extending outwardly from said lower flap. a distance sufficient for said tongue can snap into a corresponding opening formed by two cut half openings or opening directly near the outer edge of said upper flaps superimposed when the plate is formed.

  In another advantageous embodiment of the invention, the blank comprises an upper flap provided with at least one opening, for example advantageously opening on the periphery of the outer edge of said upper flap, and a lower flap provided with at least one tongue arranged to cooperate with said opening, said tongue being connected to the lower flap by a fourth fold line parallel to the second fold lines.

  FIG. 8 is a plan view of the blank according to the invention corresponding to the embodiment of FIGS. 6 and 7 of the tray.

  FIGS. 1 and 2 show a plate 1 made of cardboard sheet material, for example made of double-sided corrugated cardboard 3 mm thick, comprising a bottom 2 formed of at least one upper flap 3 and a lower flap 4 superposed .

  The lower flap 4 is provided with three tabs raised and respectively snapped into a corresponding opening 6 of the upper flap in which they are mechanically locked, the openings being of slightly smaller lateral dimension (for example of the order of 1 mm to 2 mm) to the length dimension of the tongues, forming an acute angle with the horizontal face of the bottom of the tray, (for example between 30 and 50) a kind of spring effect being obtained with the cardboard.

  In the rest of the description, the same reference numbers will be used to designate identical or similar elements.

  Figure 3 is a plan view of a blank 7 according to a first embodiment for obtaining a plate of the type shown in Figures 1 and 2.

  The blank 7 comprises a series of four main flaps 8, 9, 10 and 9 'connected to each other by parallel fold lines 11, called first fold lines, and a set of flaps 12 comprising two lower flaps 13 and 14. intercalated with two upper flaps 15 and 16 arranged on one side of the flap suite and connected thereto by second fold lines 17 perpendicular to the first fold lines 11.

  The sequence of shutters is terminated by a gluing tab 18 which, when the shutters 8, 9, 3, 10 and 9 'are closed towards each other, forms the main lateral walls of the body of the tray, the lower and upper flaps. being folded and glued to form the bottom 19 of the tray as shown in FIG.

  More specifically, the flaps 9 and 9 'forming the side walls are L-shaped symmetrically disposed with respect to the central flap 10 forming the front face of the plate. The flap 10 is substantially rectangular, of height corresponding to the height of the lower branch of the L of the two adjacent flaps.

  It is for example hollowed out at the top on its outer peripheral edge to further improve the visual access to the products.

  The fourth component 8 is itself rectangular and for example has on its upper part a notch 20 adapted to cooperate with a corresponding recess 21 of the blank 22 forming the tray cover as for example shown in Figure 5.

  The blank 22 comprises for example three rectangular flaps 23, 24, 25, each flap being provided on either side with rectangular flaps 26 and 27.

  The central flap 24 is provided in a manner known in itself 28 tear-off zones, allowing the complete opening of the top of the plate giving access to the products.

  According to this embodiment of the invention, the lower flap 14 of the set 12 of flaps of the plate is provided with a substantially rectangular tab 29 partially cut in the flap 14 and connected to the rest of said flap 14 by a third line of folding parallel to the second fold lines 17, said tab extending outwardly from the lower flap 14 for a distance sufficient for said tongue to snap into a corresponding aperture 31 of somewhat smaller size formed by two rectangular half openings 32 cut out or opening directly near the outer edge 33 of the upper flaps when the plate is formed.

  FIGS. 6, 7 and 8 show another embodiment of plate 34 and blank 35 according to the invention. The bottom is here formed by an upper flap 36 provided with three rectangular openings 37 opening on the periphery 38 of the outer edge of said upper flap 36, forming notches whose dimensions are slightly smaller than the size of the tabs to allow snap-fastening.

  The lower flap 38 is itself provided with three corresponding rectangular tabs 39, cut in said flap on two or three sides and connected to said lower flap by fourth fold lines 40 perpendicular to the second fold lines 41 joining the flaps forming the bottom of the tray with the rectangular flaps 42, 43, 44, 45 forming the walls of said tray.

  In this embodiment, the walls 42, 43, 44, 45 are provided with precut lines 46, for example bevel downwardly on two of the walls facing each other, to give a front face 47 of small height.

  We will now describe two modes of forming the box for obtaining the tray according to the embodiment of the invention more particularly described here.

  In the first case, after the box has been placed in volume (see Figure 6) simply push the tabs 39 through the openings 37 so that they lock and form stops (Figure 7). This training can be done before or after the introduction of the products in the box. But, and this is the second case, the latching of the tongues in the openings and their locking can also be done simultaneously with the setting volume of the box.

  Thus, if the box is for example placed in volume around a mandrel, we can take advantage of the sequence of pressing and gluing the bottom flaps to snap the tabs, for example by equipping the pressure plates with rigid protrusions which will push the tongues into the cavities.

  It goes without saying and as it follows from the foregoing the present invention is not limited to the embodiments more particularly described. On the contrary, it embraces all variants. It is particularly applicable to any package it is a room (monoflower) or two pieces (bottom plus lid) from the moment the bottom of the tray consists of flaps partially or completely overheating.
