Description

CASE, CUTTER ASSEMBLY, OPENING METHOD
A BODY, AND METHOD AND MACHINE FOR
MANUFACTURING SUCH A CASH

The present invention relates to a box two-part packaging of the type comprising two cutouts made of cardboard or cardboard corrugated, namely a first cut forming a tray and a second cut forming a part io upper or cover for the crate, nested with said tray.

It also relates to a set of blanks to obtain such a packing box as well as processes and a machine manufacturing the the box from the set of blanks.

The invention also relates to an opening process such a fund.
The present invention finds an application particularly important although not exclusive 20 in the field of packaging for rigid products (jars, boxes ...) or semi-rigid (bags ...), making it easy to present products to outside of their transport packaging so immediate, clean and attractive, especially on 25 shelves of department store shelves.

We already know (EPO 637 548) boxes packaging of the type described above allowing a quick disconnect from the top of the box in relation to the lower part.

WO 00/63083

2 PCT / FR00 / 01015 Such boxes, however, have the disadvantage of not allowing to remove easily, quickly and completely all packaging products, to be presented aligned on a shelf.

The present invention aims to provide a box and a set of cuts answering better than those previously known to the requirements of the practice in particular that it authorizes the complete removal of the tray and the lid of the packaging by some simple movements, without touching products, which completely eliminates packaging of products and thus authorizes a impeccable presentation, immediate and in one all products contained in the packaging on the shelves in the shops.

The box is moreover mountable in automatic with strong rate (over twenty cases / min) while having a great solidity, the crates as well obtained by the invention being otherwise easily stackable on pallet.

In this. purpose the present invention proposes including a packing box in two parts of the type described above, characterized in that the body has a first wall transverse side arranged to be grasped by a user, connected to the rest of the fund by partially precut junction lines allowing manual tearing by the user of WO 00/63083

3 PCT / FR00 / 01015 said first wall relative to the rest of the checkout, 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 a separation between walls by spacing manual obtained by exerting a force perpendicular to the walls.

Per partially pre-cut portion (or also sometimes here after say more simply pre-cut portions) means a portion frangible that only stands by a few points or ls of attachment with the rest of the cut and which is therefore easily disconnected from the cutting, by traction perpendicular to the plane of said cut.

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

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

If, on the other hand, the spreading force exerted walls is frankly perpendicular to the walls, these then become disconnected easily WO 00/63083

4 PCT / FR00 / 01015 manually, without delamination of the cardboard, for example with a force of the order of 5 to 10 Newtons, advantageously and for example after passing a hard point requiring an extra effort of some Newtons from the user, using for example his thumb as a foil and / or lever arm to pass this hard point.

In addition, it should be noted that as long as the first side wall of the crate is not io torn manually by the user, the tray and the lid retain their rigidity, which does not allow any gap or yawn between tray and lid, moreover advantageously still prevented by the hard point or points mentioned is above.
Nesting between tray and lid can be internal or external, that is to say with the walls of the tray located externally to the lid or internal to the lid.
Advantageously the first side wall transverse is formed by the collage one on the other of two first side walls, respectively of the lid and the tray.
The first side walls of the tray and 25 of the cover, which are here fixed together by a classical solid bonding, for example by strips of hot melt type glue, also ensure a good rigidity of the box, without possibility of separation, except by delamination of the board.

WO 00/63083

5 PCT / FR00 / 01015 Collage point collage, like partially pre-cut portions that snap easily from the rest of the cutout to which they originally belong excludes by cons the delamination.

To be entered manually, the first wall transversal side of the body contains or is for example secured to input means.

According to the embodiment of the invention more lo especially described here these means of capture and the partially precut junction lines of the first transverse side wall are in particular provided for the removal of said first side wall of the body by a user by fully releasing the feet of products.

Also advantageously only the line of junction partially precut of the first transverse lateral wall of the crate with the bottom coincides with the corresponding edge and / or only partially precut junction lines with the adjacent sidewalls of the first wall lateral coincide with the corresponding edges.

The user, who can enter for example to full hand the side wall to pull off, exerts a WO 00/63083 CA 02370696 2 ~ 001-10-16 pCT / FR00 / 01015 more pulling force than force spacing to separate the portions partially precut, for example a force of traction from one to four kilograms.

Advantageously, it is a whole side face or substantially a whole side face (i.e.
less than 70% of the face) which is tear-off, for example advantageously at once by vertical pull or horizontal, or two shots per draw horizontal on each side, the foot of the products being always clean to be cleared on the side of said face tear.
Advantageously the junction lines partially precut (also below) sometimes called more simply junction lines pre-cut) are initially, or later, cut to present a first hard point, due to a more large length of cut cardboard portions, then a more fragile part with longer pre-cut parts, possibly consolidated by one or two intermediate hard points additional, and ending for example by a part easier to tear off.
Splitting the pulling efforts allows to better guarantee the non-separation of the first side wall in case of side impacts and / or unforeseen efforts on the fund.

Such provisions also allow, after tearing of the first wall of the packaging and splitting of glue points or portions partially precut, for example also connected to the rest of the cut that carries them through pre-cut lines with one or more hard points, to 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 it slightly and / or sliding horizontally along the products.

Figure 1 shows a parallelepiped box 1 in two parts, namely a rectangular tray 2 and a lid 3 formed from cut-outs Corrugated sheet material, for example double-sided corrugated board 3 mm thick.

The body has a first side wall transverse 4, tear-off, rectangular or substantially rectangular, formed by gluing On each other for example by four lines of hot melt glue, first wall rectangular 5 of the tray and a first rectangular wall 6 of the cover vis-à-vis.

The first wall 6 of the lid is connected with the upper part of the box by a line precut 7 which crosses the wall from one side to the other, for example at 4 / 5th of the height of the wall, or near the top of the lid, and includes a recess 7 ', located in the middle of the line, by example formed by a half moon allowing a user to slide two fingers to initiate a tearing and then allow him to grab the wall in full hand.

The first wall 5 of the tray is connected to side sides adjacent and at the bottom of the tray either by three fold lines 8, 9 partially pre-cut, which coincide with the edges of the parallelepiped that forms the box, not a single folded precut line 9 'junction with the bottom, as shown on the first cutout of FIG. 3, the other edges 8 'of the first wall being free then.
Partially precut lines (still sometimes called simply in the body of the text, pre-cut lines) are obtained by perforating the dotted cardboard with cut-out blades perforating nets. The dotted lines are therefore defined by alternating perforated lines called cutters, and non-perforated lines called attachment points.

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

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

Advantageously we will also vary Dl 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 side walls 10, 11 and 12, to know two longitudinal side walls 10 and 11 and a second transverse lateral wall 12.

More specifically, and by also doing reference to Figures 2 and 3, the box consists of two cuts, namely a first cut 13 comprising a central rectangular flap 14 and two side flaps 15, connected by first lines of folding 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 portions partially precut (again called sometimes more simply in the body of the text, pre-cut portions) and the rest of the cut are for example planned with a larger Di value than D2.

The tray includes as we saw a first set of flaps 19, which may include two first side flaps (here not shown in Figure 3) and one first side flap 5.

The tray also includes a second set 20 flaps connected to the flaps and / or between them known in itself by second lines of normal folding.

The first flap or flaps are connected to the flaps corresponding and / or to the first main flap, by the second fold lines 8, 9 or 9 ' pre-cut, said flaps being suitable for forming partly the first tear-off wall of the box.

The second cut 21 (see FIG.
as for it four rectangular panels 22 and one gluing tab 22 ', connected together to two by third fold lines 23, 23 ', parallel and a set of rectangular flaps 24, 25 identical two by two, 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 folding lines pre-cut 23 ', superimposed with lines 8' or 8 of the tray.

The front face formed by the panel 22 glued in lower part on the central flap 5 of the tray, for example by gluing lines 27 (see figure 1), is fully tearable according to the arrow 28, considering the junction lines or edges precut.
Thanks to the gripping hole 7 'provided at the level of the junction line between cover and panel central, it is indeed possible, when the cash is closed and glued, to seize and then tear off a only block the entire front of the crate.

The tray, which can be seized the other side by a handle (not shown), will therefore it can be removed by pulling it horizontally and then the upper or cover, which can be grasped by its part lower located on the other side of the first game tear off 19.
Figure 4 shows a set of cutouts 30 comprising a first cut 31 suitable for forming a rectangular tray, including a shutter central rectangular 32 connected by first fold lines 33 to side flaps rectangular 34, on both sides, and two games and 36 small rectangular flaps, identical, connected to said shutters by second lines of folding 37 and 38 perpendicular to the first lines of folding, namely a game 35 with lines of normal folding 37 and a 36 game with lines of Partially pre-cut bending 38, according to the invention, able to form part of the panel tear.

The cutout set also includes a second cut 40, of lid, formed of three rectangular panels 41, 42 and 43, namely a panel 41 for forming the top of the lid and two panels 42 and 43 for forming the sides transverse of the lid.
The panel 42, intended to form the side transversal bottom of the box, is connected to the central panel by a normal fold line 42 '.

The panel 42 advantageously comprises a handle 45 gripping formed by a recess, and a portion partially precut 46, according to the invention, central, rectangular open on the board edge, glued or otherwise stuck on the 35 flaps game main flap of the first cutting.

Panel 43 is intended to form the first wall of the crate, with the game of flaps 36.
It comprises an upper line of junction 44, 44 'or 4411 with the top of the lid, partially precut, with a central hole 45 gripping.

Line 44 is located in panel 43 that she crosses from side to side, for example with a slight s radius of curvature directed upwards, allowing to leave a band after tearing.

Line 44 ', another embodiment of the upper junction line, is meanwhile confused with the fold line or ridge of the checkout, and line 44 "third mode of realization from each side of an angle of the crate, is then in the top of the lid which is partially torn off at the same time as the panel, and is for example trapezoidal is isosceles.
The central panel 41 and the side panels 42 and 43 each have two sets of side flaps rectangles 49, 50 and 51, connected by lines of folding to the corresponding panel.

The set of flaps 49 is connected to the panel 43 to the junction with the upper line of junction 44, 44 'or 4411, by fold lines 52 partially precut to allow picking.

FIGS. 5 and 6 show the three main steps of opening the crate 1 according to the embodiment of Figures 1 and 2 with headband 26.

First of all, (arrow 28) the panel or first transverse side wall 4.

Then pull the tray 2 (arrow 53) under the feet of the products 54, that the strip 26 prevents tilt retaining the upper portion 55 of said products.

Then we erase the band 26 by rotating by tilting the lid 3, before extracting it (arrow 56) in the horizontal direction.

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

The assembly 61 comprises a first cut 62 equipped with a rectangular main shutter 63 connected to two lateral flaps 64 symmetrical with respect to the longitudinal axis 65 of said blank, comprising for example two parts of different heights.
Each lateral flap 64 is provided with a portion partially pre-cut 66, for example in the form of diamond and arranged in open border of the periphery of the lateral flap 64, for example at the level of the junction between the two parts of heights different, substantially in the center of the shutter corresponding.
Each component also comprises of on the other side a rectangular side flap, namely a side flaps 67, 68 and the other side the flaps 69, 70. The flaps 69 and 70 are connected to the shutters adjacent by a fold line partially precut 71 and the flaps 67 and 68 by a line normal 72.

The second cut 73 includes three panels, namely a central rectangular panel s 74, and two rectangular side panels 75, symmetrical with respect to the longitudinal axis 76 of the cutting.

Each panel has on both sides a rectangular flap.
More specifically, the central panel 74 and the side panels respectively include a side of the rectangular flaps 76 and 77 and the other side of the flaps 78 and 79.

Flaps 78 and 79 are connected to the panel is corresponding by a fold line 80 partially precut.
When opening the cash register, it is therefore possible (see Figure 8) to tear the wall 81 of a block, formed by the flaps 78, 79 of the cover and The flaps 69, 70 of the tray, glued together, that come off because of the fold lines pre-cut, which allows the lateral exit of products 82 by pulling horizontally on the part upper or lid as indicated by the arrow 83 in FIG. 11, after stain removal of portions partially precut 66 by lateral spacing (arrow 84, Figure 9).

We will now describe the opening process of a box according to the advantageous embodiment of the invention, with reference to Figures 7 to 12.
The operator tears up all of the face before 81 of the box, the latter being connected to the rest of the packaging both at the tray, at the level of the upper part only by pre-cut folding lines.

Then the side flaps of the tray are 1o disconnected with the thumbs (Figure 9), the pre-cut portions 66 remaining glued to the panels Lateral 75 The barquétte is then pulled under the product by through the handle 85.
is finally the upper part is also drawn horizontally (arrow 83, figure 11), for example to using a recess practiced, in the back side (not shown) Figures 14, 15, 16 and 17 show a set 20 101, or different elements of a set, of cut-outs of double-faced corrugated cardboard sheets, for example 2 mm thick, to form a checkout 106.
For these figures, the same numbers will be used 25 of reference to designate the cash elements and / or identical cuts or occupying the same position.

This assembly 101 comprises a first cut 102 to form the tray and a second cut 103 to form the lid of the box.

The second cut is superimposed, flat, at the first cut, and fit to form a belt internal of the box, once it formed.

The first blank 102 comprises a sequence of four components, namely two so-called lateral flaps 104 and 104 'arranged alternately with two shutters said 1041 and 1041 ', the shutters being connected between them by first folding lines 105 and 105 'parallel to each other and represented respectively in phantom and dashed lines interrupted in Figure 14, the sequence of shutters is being able to form the outer walls of the tray 106 with four sides (see Figure 16).

More specifically, the flaps 104 and 104 'are of Trapezoidal rectangle shape.

They are symmetrical compared to the facial flap 1041, which forms the back side of the container and which is taller than the rectangular facial flap 1041 'which forms the face before the tray.
The fold line 105 'between the flaps 104 and 104111 is precut, just like the fold line 105 'between the gluing tab 104a and the shutter adjacent 104 ', which will allow the lifting of the first wall.

In another embodiment these are the folding lines 105 between the shutter 10411 and the shutters 104 and 104 'which are precut (or in other words, partially precut), that is, to say with cut portions attached with points in which case it is the back side which is planned tear-off.

The flaps 104 and 104 'comprise, for their part, upper peripheral edge 107 and 107 'sloping towards the bottom, directed in the opposite direction of the flap 104 ''.

The tongue 104a is rectangular, and extends all the way up the little side.

The sequence of flaps 104, 104 ', 1041, 1041' is also provided on its lower side, a first suite 108 of rectangular flaps, via second fold lines 109 and 109 '.

The flaps 108 are intended to form the bottom 108 ' (see Figure 15) of the tray, in known manner, two of said flaps coming for example in contact with each other their outer edge to form an airtight bottom.

The fold line 109 'between the shutter 1041' and the corresponding flap is precut.

The second cutout 103 has four shutters rectangular, which will be hereafter called panels to better differentiate them from the flaps of the first cutting.
This is a first rectangular panel 110 central and three rectangular panels 111, 112 and 113, interconnected by third fold lines 114 and 114 ', namely two panels 112 and 113 connected on both sides to central panel 110 and an end panel 111 connected to the other side of the panel 112 by a line of folding 114 'precut.

Cutout 3 includes a second suite 115 of flaps, identical to the first suite 108 of flaps, connected to adjacent panels by fifths fold lines 116 and 116 ', perpendicular to the first lines 114, and intended to form the 115 'cover of the box, the fold line of junction 116 'of the panel 111 with its flap being Pluck.

An end tab 113a is moreover provided, connected to the end panel 113 on a only part of the height of the latter, situated on the side of the fold lines 116, by a line of pre-cut bending 114 '.

The tongue 113a is placed on the same side as the tongue 104a, and its length is for example equal at the height of the panel 113, less a length equal to or slightly greater than the length of the tongue 104a.

Tabs 104a and 113a are also provided and arranged to close on the walls facing each other cutouts formed without overlapping each other although they are on the same side (see Figure 15), and to be peelable according to the invention.

Advantageously, the fold lines 114, 114 'and 105, 105 'of the two cuts are parallel and staggered, arranged to make up the extra thicknesses of cardboard when folding.

The tray also has two portions precut, for example oval, in closed lines 120 and 121, located entirely at a distance from the edge 107, 107 'flaps 104, 104'.

Referring to Figures 16 and 17 the tray io therefore comprises a first set of flaps 1-08 forming the basically related to the corresponding parts by fold lines 109 and 109 ', the latter being Pluck.
Similarly, the second cutout 103 includes four is rectangular flaps 119 connected to the panels corresponds by fold lines 116, one of which 116 'is precut.
A gripping port 122 is provided at the level of of the fold line with the center panel, which 20 allows, when the crate is closed and glued, to grab the wall and tear off a single block the entire front of the body according to the arrow 123.
The tray, for example that we can catch from the other side by the handle 124 (obviously), goes When it can be removed as previously described, then the upper part, which can be entered by the bottom flap on the other side of the first tearing game.

The horizontal glue lines are represented in Figures 16 and 17, the shutter 104111 being glued on the vertical panel 111.

The pre-cut portions 120 are themselves towards the center of the tray, which avoids yawning in the absence of side flaps which usually hold the tray in the good position.

The portions 120 can also advantageously to be in open lines.

FIG. 18 shows a box 130 at eight sides according to an embodiment of the invention comprising a first element 131 forming container and a second element 132 forming the part 1.5 upper body, whose flaps 133 are open to allow the filling of the box formed.

This is, according to the embodiment of the invention described here, rigid and non-foldable a times the tabs glued on the walls vis-à-screw, and includes pre-cut fold lines 134, 135, 136, 137 allowing the lifting of the face 38 with cut corners.

A recess 139 is for example provided on the one hand and else in the panels of the second element 132, level and a little above the top of the tray, which facilitates the extraction of said second element, after disconnection of it by compared to the first element.

FIG. 19 shows a mode of making the first cut 141 and second cutting 142 of an assembly according to the invention to obtain a box of eight sides of the type of that shown in Figure 18.

The first cutout 141 comprises a series of eight shutters 143 and a rectangular gluing tab 144, the flaps and the tongue being connected between them by parallel fold lines 145 and 145'to each other, namely four shutters 146, 147, 148 and 149, and four intermediates 150, 151, 152 and 153.

The main shutters 146, 147, 148 and 149 are each connected by second fold lines 154 and 154 'to a series of flaps 155, said second fold lines being perpendicular to the first fold lines.

One flap out of two is of substantially rectangular and has both sides at least partly outwardly of said flap from the second fold lines, said second fold lines 154, 154 'being substantially aligned or aligned with each other other.

The other two flaps are themselves rectangular.

More specifically, the main components are consisting of two rectangular shutters namely a first small rectangular flap 147, central, and a second large rectangular shutter 149, located on the side one end, and two main form flaps substantially trapezoidal rectangular namely a first strand 146 and a second strand 148 both symmetrical with respect to the small flap 147 and having an angled side 146 ', respectively 148 ', directed outward and upward to from the small rectangular shutter 147.

The main shutters are separated by shutters io secondary rectangular or substantially rectangular, as indicated above, secondary flaps being devoid of flaps.

According to the embodiment of the invention more particularly described here, the main component 146 has a detachable portion 156 extended or not, by a recess 157 making it possible to catch up with the overthickness during the formation of the tray around the top element of the crate, element upper corresponding to the second cut 142.

Component 148 also includes a detachable portion 156 ', but who in this mode of realization is not necessarily prolonged recess.

The intermediate flaps 150 and 151 are connected adjacent main flaps 146 and 148 by pre-cut folding lines 145 'and the flap rectangle connected to the flap 154 by a line of pre-cut bend 154 '.

The cutout 42 comprises a series of eight shutters rectangular 160, 161, 162, 163, 164, 165, 166 and 167 terminated by a rectangular tongue of fixing 168.

The shutters are connected to each other and to the tongue by third fold lines 169, 169 'parallel to each other.

More precisely, they consist of four main shutters 160, 162, 164, 166, separated two to two by three secondary flaps 161, 163, 165, the last component 166 is also provided with a component end 167, disposed at the end of the sequence of flaps when the flaps are flat and connected with the rectangular tongue 168 on which he It is glued when the box is formed.

The tongue 168 is located on the side of the line of folding 171, with respect to the flap 160, its edge higher 171 'being in the extension of said folding lines 171.
The tongue 168 extends over a height by example arranged not to cover the tongue 144 when the cuts are assembled. She is for example equal to half the height of the shutter 160, the tongue 144 being of height a little less than this dimension.

In the same way as for cutting 141, the cutout 142 comprises, located on the other side by report after 155, a series of flaps 170 connected to the main shutters by fourth fold lines 171, 171 'perpendicular to the third fold lines 169.

This series of flaps is for example identical to the flap suite 155 described with reference to the cutting 141.

In the embodiment described here, the wall detachable is constituted by the set of shutters 161, 162, 163 for the second cut and set shutters 150, 147, 151 for the first cut.

These two sets are attached to each other by collage and are connected to the main shutters adjacent and flap by fold lines precut 145 'or 169', and 154 'or 171'.

Moreover, the fold lines 145 of the is first cut are advantageously provided and placed progressively off the opposite side flap 164 with respect to the fold lines 169 of the second cut to make up the extra thicknesses.

The offsets calculations are done in a known manner, adapting them to the eight-part case.

Portions 156 and 156 ', as well as shutter 147 are fixed by gluing (for example hot melt) on parts 160 and 164 and 162 of the second cut-out vis-à-vis.
When the crate is formed the tab 144 is glued on the flap 153, the tongue 168 on the outside of the flap 167, and the flaps 55 sets.

Figures 20 to 23 show another mode of embodiment of the invention.

It further includes a set of flaps 264 substantially rectangular presenting for two of them, opposite, lateral edges starting at least partly outward biased to come in line with the cut corners when the crate is formed.

Two main opposite pans (non-adjacent) 260 each include on their peripheral edge lower 265, in an open line, centered relative to to the panel concerned, a pre-cut portion 266 by rectangular example.

Portions 266 are intended to be glued on the inside of the walls formed by the shutters 253, which allows extraction as shown in FIG. 20, the edges 265 being merged or offset by a thickness of cardboard, or substantially, with respect to the first fold line 253 ' joining the central flap 252 with the side flap 253.

The vertical fold lines of a set central panel 260 and its two cut corners adjacent 261, the second cut 259 forming cover, just like the fold line 261 horizontal of said panel 260 with the upper flap as well as the corresponding fold lines of the tray 251, on the one hand between transverse flap 254, and on the other hand between small end flaps 255 and 256, are precut according to the invention.

The box 267 obtained is advantageously mounted around a mandrel, the second cut 259, previously glued to the first cut as shown in Figure 23, being wrapped around a eight-sided mandrel, then the first cut being folded on the bottom of the mandrel with gluing end flaps 256, by successive application on the cut corners formed by the shutters intermediate 261, then on the side flaps adjacent 253 (see Figure 20).

Figure 24 shows a box 340 according to another embodiment of the invention, provided with a tray 302 of the type described above.

The upper part 341 is here in one piece, the tear-off face being only a portion tear-off at the bottom of the packaging.

Figures 25, 26 and 27, 28 cutouts show a box 342 including a tray 343 formed by a first cut comprising two side flaps 344, each provided with two portions pre-cut 345 and 346, rectangular or substantially rectangular, one of which is 345 located at one end of the tray and is free on three sides and the other 346 is free on two i5 sides and the like to the precut portions 17 or 66.
The tray includes a first set of flaps 347, namely two side flaps (here no shown in the figure), glued to the side flap central 348 and / or a single central side flap 348 (illustrated embodiment).

The flap or flaps are connected to the flaps corresponding by fold lines 349 precut.

Similarly, the second cut 350 includes three rectangular flaps 351 and 352 connected to the panels corresponding by pre-cut fold lines 353.

A gripping port 354 is provided at the level of of the fold line with the center panel, which allows, when the crate is closed and glued, to tear off the whole front face of the crate according to arrow 355.

The tray, for example that we can catch from the other side by the handle 356, will then be able to be removed as previously described, then the upper part, which can be entered by the party lower flap lo located on the other side of the first tearing game.

The horizontal glue lines are represented in Figures 25 and 26, the flap 348 being glued on the vertical flaps 352, just like the flap 1.5 central 351 panel.

The pre-cut portion 345 is in turn and glued very forward of the tray, which avoids yawning in the absence of side flaps which usually hold the tray in the 20 good position.

Figures 29 to 32 show another mode of embodiment according to the invention.

Figure 30 shows a first cut 343 identical to that described with reference to FIG.
25 27.

The second cut 359 (see FIG. 29) comprises as for her four rectangular 360 panels interconnected by third fold lines 361, 361 ', parallel and one set of flaps Rectangulars 362, 363, 364, 365, two identical to two of which one (363) is planned to come into front of the packaging and is connected to the shutter adjacent 360 by a precut line 366.

The said adjacent component is itself connected to its adjacent shutters by fold lines precut 361 '.

Here again the front panel formed by the 360 panel glued at the bottom on the central flap 348 of flap, for example by glue lines 368 (cf.

figure 32), is tear-off entirely according to the arrow 369, considering the fold lines or pre-cut edges 349, 366 and 361 '.

Figure 33 shows another embodiment forming a package according to the invention, in several steps A to F, and then shelves (steps G to J) from a first cut 400, intended forming the tray and a second cut 401, clean to form the lid.

The first blank 400 comprises a sequence of three rectangular shutters 402, 403, 404, large dimensions (of the size of the load), connected between them by first fold lines 405.

The suite includes two sets of flaps rectangular 406 and 407 connected on both sides corresponding flaps, by connecting lines partially precut 408 for the game 406 and by normal fold lines 409 for game 407.

Specifically, the flaps of the game 406 include two side flaps for example each provided with a pre-cut bonding tab 410 located towards the central flap and likely to remain stuck to a portion 411 vis-à-vis the central flap.

The junction line between central flap and flap corresponding is for example in the form of S2 horse on the fold line whose top is located on flap 403 and side branches are in the Rabat.

The set of flaps 407 includes two side flaps 412, each provided at their end external of two pre-cut open portions 413.

The second cutout 401 comprises, in turn, three parts, namely a first component 414 from above and two small side flaps 415 of the type described in reference to Figure 27 for example. Each component 414, 415 has two small rectangular flaps 414 ', 41411 and 415', 415 "located on both sides, the flaps 414 'and 415' being connected to the shutter by pre-cut folding lines.

We will now describe the formation of the fund with reference to steps A to F.

The blank or cut 400 is brought flat, then after sizing, shaped (step B) by raising the side walls 402 and 404 to form the body open 417 (step C). The side flaps of the games 406 and 407 are of width equal to half of the load 418, to form a complete face, the flaps coming aboard.

The load 418 (here rectangular boxes 419 stacked) is then introduced (step D) into the crate, then the cutout 401 is placed on top, to come to style the peripheral edges of the walls verticals formed by shutters 402 and 404, which coincides with the upper edges of the load.

The shutter 415 and the flaps 414, 41411, 415 ', 415 "
are then folded and glued on the upper edge of the body 420 thus closed (step F).

When it is shelves, the wall 421 is torn off, which is possible because of the lines of folding and / or pre-cut junction.

Then the lid part formed by the blank 401, and which forms the tray in the lower part on the radius is extracted (step H), this being rendered possible thanks to the separation of the portions precut 416 stuck on the walls 402 and 404.

Then the upper part 422 is removed from the same side that the tray and the load 418 is as well released on the shelf.

FIGS. 34 and 35 show another mode of crating according to the invention, this time-using the principle of wrap around the load 500.

The lower part or tray 501 is of the type described for example with reference to the tray 36 of Figure 4.

This is pre-glued, then by example formed before or still wrapped around the load 500.

Similarly, the lid portion 502 includes three major components 503, 504, 505, namely a component 504 forming the top of the lid, and two shutters rectangular 503, 505 lateral the size of the height of the load 500.

The flap 504 is connected to the shutter 503 so lo similar to the cut 400 described with reference to the FIG. 33 by a pre-cut junction line 506 in S2.

Component 505 includes a portion precut 507 sizing on the bottom of the type described is on panel 42 of Figure 4.

The main component 503 also includes and other two flaps 508 and 509, rectangular of the size of the load, height dimensions walls of the tray, flaps themselves provided with 20 rectangular flaps 510, 511, for example from the width equal to the part of the load, the flaps 510 located on one side of the flap 504 being connected by pre-cut fold lines 512.

The cut 502 is wrapped around the load 25 stuck on the tray from below.
flaps 504 and 505 and in one embodiment, by the pre-cut portions 513 of the tray, forming the cash register 514.

Referring to Figure 35, and similarly to what is described with reference to Figure 34, the wall 515 is torn off, then the tray 516 removed, before removing the cover 517 to release fully charge.

Figure 36 shows in perspective a view of an 1150 machine in accordance with a embodiment of the invention.

More precisely and also with reference to the FIG. 37, the machine 1150 comprises a frame support 1151, a first set 1152 supply cutouts 1153 for forming the tray, and a second set 1154 feeding cutouts 1155 intended to form the upper part of the package according to the invention.

These power realization sets are known in themselves and make it possible to apprehend cuts one by one via suction cups aspirants then switch them on a platform 1156 on which the set of cuts according to the invention is formed.

More specifically, with reference to FIG.
lower cut 1153 is first flat after extraction of the power supply concerned.
Then a sizing of the pre-cut portions is realized and the second cut 1155 intended to form the whole is then taken by the rocking system suction cup 1154 to be placed from accurately and then applied (press 1157) on the first cut 1153 which becomes thus secured by gluing only through a portion Pluck.

Then all the cuts thus formed is moved horizontally (see Figure 38) by through transfer means 1158, by example consisting of belts 1159 in noria, under a parallelepiped mandrel 1160, for example at some distance from it.

During transfer the end flaps 1161 and the second pre-cut portion are glued by 1162 means of the hot glue gun type melt, with vertical injection.

Then the central flap of the first cut (by example) is pressurized on the mandrel, by example by the method and with reference to the device described in patent EP 0 468 860.

Similarly, the set of cuts is then Wound (see Fig. 39) around the mandrel by through a 1163 swing arm system and the shutters and / or panels of the cuts are applied under pressure (see Figure 40) by the pusher plate intermediate 1164 on the Mandrel 1160 so that the crate is formed into part.

At the same time, the flaps intended to form a lateral side of the entire crate formed are applied on the bottom of the mandrel via of pushing cylinders 1165.

Once the crate is formed, it is ejected to form a fillable crate from the side, according to the embodiments more particularly described here.

We will now describe, in particular with reference in FIGS. 37 and 38, the steps of the method according to a embodiment of the invention.

The cuts are placed in the shops of storage consisting of conveyor belts.

The first 1153 cut-out (tray) and the second cut 1154, body (upper part) are then depilated.

Then there is positioning of the second cut 1154 between a pusher and movable stops (no shown).

The second cut is then transferred to a bottom stop then is set up on the first cutting by a rod / crank system (no represent).
During this transfer, the junction zone, that is, say the first pre-cut portion here belonging at the first cut, is glued on top.

It is then pressurized (press 1157) at level of the junction and release stops.

The transfer of the set of cuts and solidarized is then carried out under the mandrel 1160, thanks to the 1159 belts.

During this transfer the set of cuts completes to be pasted on the flaps and on the second pre-cut portion of junction (glue 1162).
Then, there is volume development of the box by rise of coating arms, pressurization of lower plater 1166, pre-ply panel outer junction of the first cut on the second cut, then simultaneous folding of the whole longitudinal flaps, finally folding and setting pressure of the transverse flaps and the panel of junction.

The body is thus put in volume with a folding reversed.

Finally, the packaging is ejected thus formed, for example by a jack located at inside the mandrel.

It is of course possible to use other types of store, for example arranged for a unstacking from above or from below.

All unstacking movements are indeed possible (linear by cylinder, or rotary by system with belts).

The accuracy of these store types is then provided by reciprocal-type settings, ie say allowing to adjust the grip area in depending on the position of removal.

This type of store by unstacking from above is also applicable on any type of coating, including around the product itself (wrapping technique around in Anglo-Saxon terminology).

As it goes without saying and as it also results of the foregoing, the present invention is not limited to more embodiments particularly described. She embraces contrary all variants, especially those where both cuts are folded and glued flat one on the other; or where the cuts are put in tunnel of said assembly already glued via some pre-cut portions.
