Abstract

The crate (1) consists of a rectangular tray (2) whose sides (15) may be overlapped by the sides (10) of the lid (3). The ends (6) of the lid may overlap the ends (5) of the trays. The top of the lid maybe formed by folding flaps. A portion (4) of the end wall may be torn away by the user when opening the crate. There are pre-cut portions and gluing points (16,17) on the side walls. The crate may be made of plain or corrugated cardboard.

Description

The present invention relates to a two-part packing case of the type comprising two blanks made of cardboard sheet or corrugated cardboard material, namely a blank of a carton box or a corrugated carton. first cut forming a tray and a second cutout forming an upper portion or cover for the box, imbricated with said tray.

It also relates to a set of blanks to obtain such a packing box and a method of opening such a box.

It finds a particularly important application although not exclusive in the field of packaging for rigid products (jars, boxes ...) or semi-rigid (bags ...), to easily present the products outside of their packaging. transport in an immediate, clean and attractive way, especially on the shelves of department stores.

Already known (EPO 637 548) packing cases of the type described above allowing a quick disconnection of the upper part of the box with respect to the lower part.

Such crates, however, have the disadvantage of not allowing to easily, quickly and completely remove all products from the package, to be presented aligned on a shelf.

The present invention aims to provide a box and a set of cuts better than those previously known to meet the requirements of the practice in particular that it allows the complete removal of the tray and the lid of the package by a few simple movements, without touching the products, which completely eliminates the packaging of the products and thus allows an impeccable presentation, immediate and all at once, of all the products contained in the packaging on the shelves in the stores.

The box is moreover mountable in automatic at a high rate (greater than twenty boxes / min) while presenting a great solidity, the boxes thus obtained by the invention being moreover easily stackable on pallet.

For this purpose, the present invention proposes in particular a two-part packing case of the type described above, characterized in that the box has a first transverse lateral wall arranged to be grasped by a user, connected to the rest of the box by partially precut junction lines allowing manual tearing by the user of said first wall relative to the rest of the body, and in that one or the other side walls of the tray are only fixed respectively to one or the other side walls of the lid by one or more portions partially precut and / or one or more bonding points allowing separation between walls by manual separation obtained by exerting a force perpendicular to the walls.

By partially precut portion is meant a frangible portion which holds only by a few points or attachment parts with the rest of the cut and which is thereby easily detached from the cut, by traction perpendicular to the plane of said cut.

The partially precut portion (s) and / or the bonding point (s) are arranged to have a good resistance in the vertical direction, that is to say as long as the forces are exerted essentially in the plane of the walls.

This resistance is particularly perfectly sufficient to allow the transport of products even if the package is grasped by the lid.

If, on the other hand, the separation force exerted between the walls is positively perpendicular to the walls, they then easily separate manually without delamination of the carton, for example with a force of the order of 5 to 10 Newtons, advantageously by example after passing a hard point requiring an extra effort of a few Newtons from the user, using for example his thumb as a foil and / or lever to pass this hard point.

In addition, it should be noted that, as long as the first side wall of the body is not torn manually by the user, the tray and the lid retain their rigidity, which does not allow spacing or yawning between tray and lid, furthermore advantageously still prevented by the hard point mentioned above.

Advantageously, the first transverse lateral wall is formed by gluing one of the other two first side walls, respectively of the lid and the tray.

The first side walls of the tray and lid, which are here fixed together by a conventional solid bonding, for example by strips of hot melt glue, also ensure good rigidity of the body, without possibility of separation, if it is by delamination of the cardboard.

Adhesive bonding, such as partially precut portions that easily tear from the rest of the cut to which they originally belong excludes delamination.

To be entered manually, the first transverse lateral wall of the box comprises or is for example integral with gripping means. According to the embodiment of the invention more particularly described here these gripping means and the partially precut junction lines of the first transverse side wall are in particular provided to allow tearing of said first side wall of the box by a user by releasing especially the feet of the products.

The partially precut junction lines of the first side wall with the rest of the package are advantageously coincident with the edges of the body, between walls, bottom and cover.

 Also advantageously only the partially pre-cut junction line of the first transverse side wall of the box with the bottom coincides with the corresponding edge and / or only the partially precut junction lines with the adjacent side walls of the first side wall coincide with the corresponding edges.

The user, who can grasp, for example, the side wall to be torn off, has a greater pulling force than the spreading force in order to separate the partially pre-cut portions, for example a pulling force of one to four. kilograms.

Advantageously, the partially pre-cut junction lines are initially, or later, cut to present a first hard point, due to a greater length of the cut portions of cardboard, then a more fragile part with longer pre-cut parts, possibly consolidated by a or two additional intermediate hard points, and ending for example with an easier to tear part.

The splitting of the tearing forces thus makes it possible to better guarantee the non-separation of the first lateral wall in the event of lateral shocks and / or unforeseen forces exerted on the body. Such arrangements also allow, after tearing of the first wall of the package and splitting the bonding points or portions partially pre-cut, for example also connected to the rest of the cut that carries them by precut lines with one or more hard points , remove the tray without the products while the user holds the lid in place on the products, then remove the lid of the products, for example by lifting slightly and / or sliding horizontally along the products.

In advantageous embodiments, one and / or the other of the following arrangements is also employed: the upper, partially pre-cut connecting line of the first side wall of the box with the lid is located on the lid; - The upper junction line partially pre-cut the first side wall of the box with the lid is located on said first wall, leaving an upper band secured to the lid after tearing.

Such an arrangement will allow a blockage of the upper part of the products during the removal of the tray under the feet of the products, which in some cases could have unbalanced and fall backwards; - The gripping means of the first wall of the body comprises a handle, for example constituted by a recess centered on the upper junction line of said wall; the one or more partially precut portions and / or bonding points between the tray and the lid belong to the second lateral transverse wall of the box, opposite the first transverse transverse tear-off wall; - the lid is nested in the tray; - The box has at least two partially pre-cut portions or bonding points respectively located on either side of the longitudinal side walls of the body; - The partially pre-cut portion or portions belong to the tray; - The partially pre-cut portion or portions are precut according to an open line; the first cut comprises a series of three shutters, namely a central flap forming the bottom of the container connected laterally by first folding lines with two lateral flaps forming at least partly the longitudinal side walls of said container, said series comprising at least one transverse flap located on one side of said flaps to which it is connected by at least a second partially precut fold line perpendicular to the first fold lines, said transverse flap at least partly forming the first transverse side wall of the tray; - Each side panel comprises two portions partially precut; the second cutout comprises three panels, namely a central rectangular panel forming the upper face of the crate cover connected laterally by third fold lines with two lateral panels forming at least partly the side walls of the crate, secured to the first cut respectively for one via said one or more partially pre-cut side portions, or said gluing points, and for the other via gluing lines; the second cutout comprises two sets of side flaps situated on either side of said panels, to which they are connected by fourth fold lines located opposite said second fold lines of the first cut, the fourth lines folded between flap and one of the side panels being partially precut; the second cutout comprises at least four panels respectively connected to each other by fourth fold lines parallel to the second fold lines of the first blank, and an end gluing tab, the four panels comprising a set of flaps located on the side opposite to the first cut; - Each component of the first cut comprises a transverse flap namely a central flap connected to the central flap and provided with at least a partially pre-cut portion of the bottom, and two side flaps connected to the side flaps and glued to said central flap.

The invention also relates to a set of blanks for the manufacture of a box as described above.

 The invention also relates to a set of blanks characterized in that it comprises two cutouts respectively formed each of a shutter or a central panel and flaps or side panels, namely a first cutout intended to form a tray and a second cutout intended to form the lid of the box, the first cut comprising a second transverse flap or at least one lateral flap connected to the central flap, and arranged to be secured to an adjacent side panel via at least one portion partially precut cut belonging to one of the cuts and glued to the other cut, and a first transverse flap connected on the other side to the central flap by a partially precut line, and in that a side panel of the second cut is adapted to be glued to the first transverse flap and is connected to the central panel by a partial joining line pre-cut. Advantageously, the lateral flaps of the first cutout each comprise a flap, respectively connected to the corresponding flap by a partially pre-cut fold line on the side of the first transverse flap.

Advantageously, the side panel connected to the bottom by a partially pre-cut junction line comprises two flaps connected to said side panel by partially pre-cut fold lines.

In an advantageous embodiment the first cutout comprises at least one partially precut flap and the second cut at least four panels, one connected to its two adjacent panels by partially precut fold lines, provided with a flap connected directly or by the intermediate of a band panel portion, said panel intended to form the first vertical wall of the bottom of the box, by a partially pre-cut fold line. Advantageously, the second cutout comprises four panels, one of which is connected to its two adjacent panels by partially precut fold lines.

The invention also relates to a method of opening a polygonal section box formed from two blanks made of cardboard or corrugated cardboard material, namely a first cut to form a container and a second clean cut to form the lid of the box, said box being filled with rigid or semi-rigid products, characterized in that the box having a first transverse side wall connected to the rest of the package by partially precut junction lines for tearing - on manually pulling off the first transverse lateral wall, - the walls of the remainder of the tray of the walls of the remainder of the lid are manually detached, one or more of said walls being fixed solely to each other by means of partially precut wall portions; , or by sticking points easily disconnectable, - we draw on the horizon the tray to release the tray of the products that are on it, - then remove the lid to fully release the products it contains. Advantageously, the cover having a strip after tearing of the first transverse side wall, the cover is rotated upwards to erase the strip with respect to the products before pulling the cover horizontally.

The present invention will be better understood on reading the following description of embodiments given as non-limiting examples.

The description refers to the drawings which accompany it in which - Figure 1 is a perspective view - of a box according to a first embodiment of the invention, with strip.

- Figure 2 is a perspective view of the cover of the box of Figure 1 after tearing of the first transverse side wall and removal of the tray.

FIG. 3 is a plan view of the set of cut-outs, disengaged, making it possible to obtain a box of the type of that of FIG.

- Figure 4 is a plan view of a set of blanks according to another embodiment of the invention, showing three variants of upper junction line partially precut.

- Figures 5 and 6 are schematic side views showing the opening of the box of Figure 1, with strip.

- Figures 7 to 12 show an embodiment of the method of opening a box according to the invention. FIG. 13 is a plan view of a set of blanks according to the embodiment of the invention corresponding to FIGS. 7 to 12.

Figure 1 shows a parallelepiped box 1 in two parts, namely a rectangular tray 2 and a lid 3 formed from blanks made of corrugated sheet material, for example double-sided corrugated cardboard 3 mm thick.

The box has a first transverse lateral wall 4, tear-off, rectangular or substantially rectangular formed by gluing one on the other for example by four lines of hot melt glue, a first rectangular wall 5 of the tray and d a first rectangular wall 6 of the cover vis-à-vis.

The first wall 6 of the lid is connected to the upper part of the box by a pre-cut line 7 which crosses the wall from one side to the other, for example at 4/51, e of 1 height of 1 wall, or near the above the lid, and comprises a recess 7 ', located in the middle of the line, for example formed by a half moon allowing a user to slide two fingers to initiate a tear and then allow him to grasp the wall full hand.

The first wall 5 of the tray is connected to the adjacent lateral sides and to the bottom of the tray either by three partially pre-cut fold lines 8, 9 which coincide with the edges of the parallelepiped formed by the box, ie not a single fold line. 9 'of junction with the bottom, as shown in the first blank of Figure 3, the other edges 8' of the first wall being then free.

The partially precut lines are obtained by perforating the dotted cardboard with cutting blades perforating nets. The dotted lines are defined by an alternation of perforated lines called cutters, and non-perforated lines called attachment points.

Since the distance between two attachment points, or in other words the length of cut, is called D1 and the distance between two cutting threads, or in other words the length of attachment point, is called D2, a perforating profile is thus defined by a series of two digits corresponding to D1 and D2.

Depending on the nature and weight of the papers, as well as the thickness of the corrugated board, the values of D1 and D2 are varied until the best possible compromise is found to allow easy pulling while maintaining a sufficient strength of packaging.

Advantageously we will also vary D1 and D2 on the same precut line to create more fragile points or hard points, as described above.

The body 1 also comprises three other rectangular lateral walls 10, 11 and 12, namely two longitudinal lateral walls 10 and 11 and a second transverse lateral wall 12.

More specifically, and with reference also to FIGS. 2 and 3, the box is formed of two cutouts, namely a first cutout 13 comprising a rectangular central flap 14 and two lateral flaps 15, connected by first fold lines to the central flap 14, each provided with two partially precut portions 16 and 17, rectangular or substantially rectangular, one 16 is located at one end of the tray and is free on three sides and the other 17 is located on the side of the other end and is free on two sides.

The junction lines 18 between partially pre-cut portions and the remainder of the blank are for example provided with a value D1 larger than D2.

The tray comprises, as we have seen, a first set of flaps 19, which may comprise two first lateral flaps (here absent in FIG. 3) and a first lateral flap 5.

The tray also includes a second set of flaps connected to the flaps and / or between them in a manner known per se by normal second fold lines.

The first flap or flaps are connected to the corresponding flaps and / or the first main flap, by the second folding lines 8, 9 or 9 'pre-cut, said flaps being adapted to form part of the first tear-off wall of the body.

The second cut 21 (see FIG. 3) comprises four rectangular panels 22 and a gluing tab 22 'connected together in pairs by third fold lines 23, 23', parallel and a set of rectangular flaps. 24, 25 identical in pairs, suitable for forming the top of the cover, and one of which two 24 is intended to be connected via a strip 26 to the adjacent panel 22 by the partially precut line 7.

Said panel adjacent to the flap is itself connected to its adjacent panels by pre-cut fold lines 23 'superimposed with the lines 8' or 8 of the tray.

The front face formed by the panel 22 glued at the bottom to the central flap 5 of the tray, for example by gluing lines 27 (see Figure 1), is fully tearable along the arrow 28, taking into account the junction lines. or pre-cut edges.

Thanks to the gripping port 7 'provided at the junction line between the lid and the central panel, it is indeed possible, when the box is closed and glued, to grasp and then pull out all front of the box.

The tray, which can for example be grasped on the other side by a handle (not shown), can therefore be removed by pulling it horizontally, then the upper part or lid, which can be grasped by its lower part located on the other side of the first tear-off game 19.

FIG. 4 shows a set of cutouts comprising a first cutout 31 capable of forming a rectangular tray, comprising a rectangular central shutter 32 connected by first folding lines 33 to rectangular lateral shutters 34, on either side, and two sets 35 and 36 of small rectangular flaps, identical, connected to said flaps by second fold lines 37 and 38 perpendicular to the first fold lines, namely a set 35 with normal fold lines 37 and a set 36 with lines partially precut bending 38, according to the invention, adapted to form part of the tear-off panel.

The set of blanks also comprises a second cutout 40, of lid, formed of three rectangular panels 41, 42 and 43, namely a panel 41 intended to form the top of the lid and two panels 42 and 43 intended to form the transverse sides. of the lid.

The panel 42, intended to form the transverse bottom side of the box, is connected to the central panel by a normal fold line 42 '.

The panel 42 advantageously comprises a handle 45 formed by a recess, and a partially pre-cut portion 46, according to the invention, central, rectangular open on the edge of the panel, glued or adapted to be glued on the main flap of the game 35 flaps of the first cut.

The panel 43 is intended to form the first tear-off wall of the box, with the set of flaps 36.

It comprises an upper connecting line 44, 44 'or 44 "with the top of the lid, partially pre-cut, provided with a central 45 grip hole.

The line 44 is located in the panel 43 through which it passes through, for example with a slight radius of curvature directed upwards, which allows to leave a band after tearing.

The line 44 ', another embodiment of the upper connecting line, is in turn coincident with the fold line or edge of the box, and the line 44`1 third embodiment leaves on each side of an angle of the body, is then located in the top of the cover which is partially ripped at the same time as the panel, and is for example in the shape of isosceles trapezium.

The central panel 41 and the side panels 42 and 43 each comprise two sets of rectangular side flaps 49, 50 and 51, connected by fold lines to the corresponding panel. The set of flaps 49 is connected to the panel 43 to the junction with the upper joining line 44, 44 'or 4411, by fold lines 52 partially precut to allow tearing.

FIGS. 5 and 6 show the three main stages of the opening of the box 1 according to the embodiment of FIGS. 1 and 2 with strip 26.

The first panel or first transverse lateral wall 4 is torn off first (arrow 28).

Then pull the tray 2 (arrow 53) under the feet of the products 54, that <B> l '' </ B> headband 26 prevents tilting retaining the upper portion 55 of said products.

Then the strip 26 is erased by pivoting the cover 3 by tilting, before extracting it (arrow 56) in the horizontal direction.

Figures 7 to 13 show a box 60 and a set of cuts 61 corresponding.

The assembly 61 comprises a first cut 62 provided with a rectangular main flap 63 connected to two lateral flaps 64 symmetrical with respect to the longitudinal axis 65 of said cut, comprising for example two parts of different heights.

Each lateral flap 64 is provided with a partially pre-cut portion 66, for example in the form of a rhombus and disposed at the open edge of the periphery of the side flap 64, for example at the junction between the two parts of different heights, substantially at center of the corresponding section.

Each flap also has on both sides a rectangular side flap, namely on one side the flaps 67, 68 and on the other side the flaps 69, 70. The flaps 69 and 70 are connected to the adjacent flaps by a partially precut fold line 71 and flaps 67 and 68 by a normal line 72.

The second cutout 73 comprises three panels, namely a rectangular central panel 74, and two rectangular side panels 75, symmetrical with respect to the longitudinal axis 76 of the blank.

Each panel has on both sides a rectangular flap.

More specifically, the central panel 74 and the side panels respectively comprise on one side of the rectangular flaps 76 and 77 and on the other side of the flaps 78 and 79.

The flaps 78 and 79 are connected to the corresponding panel by a partially pre-cut fold line 80.

When opening the box, it is therefore possible (see Figure 8) to tear the wall 81 of a block, formed by the flaps 78, 79 of the lid and the flaps 69, 70 of the tray, glued between them, which are detached due to pre-cut fold lines, which allows the lateral exit of the products 82 by pulling horizontally on the upper part or cover as indicated by the arrow 83 in Figure 11, after stain partially pre-cut portions 66 by lateral spacing (arrow 84, FIG. 9).

the method of opening a box according to the advantageous embodiment of the invention will now be described, with reference to FIGS. 7 to 12. The operator pulls all of the front face 81 of the box all at once. , it being connected to the rest of the packaging both at the tray, at the level of the upper than by pre-cut fold lines.

Then the side flaps of the tray are separated with the thumbs (Figure 9), the pre-cut portions 66 remaining glued to the side panels 75.

The tray is then pulled under the product through the handle 85.

Finally, the upper part is also drawn horizontally (arrow 83, FIG. 11), for example by means of a recess made in the rear face (not shown).

As is obvious and as also follows from the above, the present invention is not limited to the embodiments more particularly described. On the contrary, it embraces all the variants, in particular those in which the two blanks are folded and glued flat on one another, or where the cuts are tunneled into said set already glued by means of certain pre-cut portions. .
