Description

CAISSE, SET OF CUT TO OBTAIN SUCH

  CASE AND METHOD FOR OPENING SUCH A CASE

  The present invention relates to a packaging case forming a cardboard display, the case being of the type comprising two elements that can be manually separated from one another and inserted one into the other, respectively formed from cutouts of material made of sheet of cardboard or corrugated cardboard belonging to said assembly, the first element forming a display tray, the second element forming an upper part of the box capable of being removed so as to give access

  to the products contained in the case.

  It also relates to a set of cutouts for obtaining such a packing case as well as a

cash register opening process.

  The present invention finds a particularly important, although not exclusive, application in the field of packaging for rigid products of the cylindrical jar type, making it possible to easily present the products outside their transport packaging in an immediate, clean and attractive manner, especially on the shelves of the shelves of

big box stores.

  There are already known (EP 0 637 548) packaging boxes of the type described above allowing rapid disconnection of the upper part of the

  body in relation to the lower part.

  However, such a box has the disadvantage of not making it easy to remove and

  completely all the product packaging.

  The present invention aims to provide a box and a set of cutouts better than those previously known to the requirements of practice in particular in that it allows the complete removal of the tray and the upper part of the packaging, which eliminates the packaging of products completely and thus allows

  impeccable presentation by gondola in the shops.

  The box is also mountable automatically at high speed (more than twenty boxes / min), while having great strength and a rate of poorly formed boxes almost zero, the boxes thus obtained by the invention also being easily

stackable on pallets.

  For this purpose, the present invention notably proposes a packing box in two parts 2o comprising two cutouts in material of cardboard sheet or corrugated cardboard, namely a first cut forming a display tray and a second cut forming an upper part of the box. nested inside said tray, characterized in that the tray has two transverse vertical walls, namely a first transverse wall which can be detached manually by simple pulling outwards, from the longitudinal vertical walls of said tray and / or of the wall vertical of said upper part of the box facing one another, said first transverse wall being entirely detachable from the bottom of the tray, or repositionable flat in the extension of the bottom of the tray without creating excess thickness of cardboard, and a second transverse wall suitable for being grasped by an operator, and in that the green walls longitudinal icals of the tray are secured to the vertical walls of the upper part vis-à-vis only by one or more pre-cut lateral portions manually detachable by simple pull, and / or one or more bonding points

  manually removable by simple pull.

  By precut portion means a frangible portion which only holds by a few points of attachment with the rest of the cut and which is therefore easily tearable or separable from the cut, by traction perpendicular to the plane of

said cutting.

  By simple traction is meant a slight traction perpendicular to the plane of the wall, that is to say a force of a few Newtons, for example less than about 10, or even 5 Newtons, even 2 or 1

Newton.

  By bonding points, we mean a small

  amount of glue, which allows a solid bonding vis-

  with respect to the forces exerted in the direction of the plane of the wall, but which is easily torn off in the direction perpendicular to the wall, which makes it possible to easily dissociate, by traction perpendicular to the walls, the walls glued facing each other. screw, without

risk of delaminating the cardboard.

  Such an arrangement allows, after easy splitting of the bonding points or of the precut portions, to remove the tray under the products while the operator maintains the upper part in place on the products, then to slide the upper part horizontally on the

io products.

  In advantageous embodiments, use is also made or more of one and / or the other of the following arrangements: - the second transverse wall of the tray is provided with a handle or a gripping recess ; - The upper part has a transverse extraction face provided with a handle or a gripping recess; - the lateral precut portions which belong to the first cut; - the lateral precut portions are

  cut along an open line.

  Advantageously, they are so with one side completely free towards the first transverse wall. Thus, when the tray is going to be erased by horizontal traction under the feet of the products, the precut portions which remain glued on the upper part will not encounter any obstacle, thus facilitating or allowing horizontal extraction. - The first cut comprises a series of three flaps, namely a central flap suitable for forming the bottom of the tray connected laterally by first fold lines with two lateral flaps at least partially forming the longitudinal vertical walls of said tray, said suite comprising at least one transverse bottom flap located on one side of said flaps to which it is connected by at least one second fold line perpendicular to the first fold lines, said transverse bottom flap forming at least partially the first transverse wall of bottom of said tray, - the second cut has three panels, namely a central panel forming the upper face of the upper part of the body, connected laterally by third fold lines to two side panels forming at least partially the side walls of the body to be secured with the side flaps of the first cut via lesd the side precut portions, or

bonding points.

  Advantageously, the panels comprise two sets of lateral 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.

  Advantageously, the fourth fold lines are offset with respect to the second fold lines, of a thickness of cardboard inwards to better allow the upper part of the box to be placed inside the tray; - the lateral precut portions are cut along a closed line; - the precut side portions belong to the side panels of the second

cutting.

  - There are two lateral precut portions symmetrical with respect to the longitudinal axis of the packaging; - There are four symmetrical lateral precut portions two by two with respect to the longitudinal axis of the packaging; - The second cut has at least four panels respectively connected to each other by fourth fold lines parallel to the second fold lines of the first cut, and an end bonding tab, the four panels comprising a set of flaps located on the side opposite the first cut; the lateral precut portions leave at an angle from the junctions between the first and second fold lines towards the outside of the first cut, for example with an angle of between 5 and 30 relative to the corresponding first fold line; - The upper part has a vertical bottom wall separated or separable from the longitudinal walls by pre-cut vertical fold lines, the central flap of the tray comprising a central transverse flap connected to said bottom by a pre-cut fold line and glued to

said vertical bottom wall.

  Such an arrangement allows the complete and simultaneous removal of the bottom walls of the container and of the upper part, completely freeing an external face of the products contained in the box, which allows the removal of the container and the part

  superior by horizontal traction.

  - Each flap of the first cut has a transverse bottom flap, namely a central flap connected to the central flap and provided with two pre-cut bottom portions and two side flaps connected to the side flaps and glued to said portions

precut background.

  Such an arrangement allows the central bottom flap to be flattened without presenting an excess of cardboard with respect to the bottom, the precut portions remaining glued to the lateral flaps which are erased on the side in the extension of the vertical longitudinal walls of

the tray.

  Advantageously, the upper part has a transverse vertical wall, at the bottom, formed of three flaps, two of which with bellows, connected to the

third.

  In other words, two side flaps, belonging respectively to the side panels of the second cut, each have a 45 fold line starting from the fourth fold lines outwards from the junction between third and fourth fold lines; Such an arrangement will allow the automatic conformation in the tunnel of the flaps which can slide horizontally on the load of the body, thus allowing the extraction of the upper part of the body horizontally and not only from above.

as in the prior art.

  The invention also provides a set of

  cuts to obtain a case of the type described below

before.

  The invention also proposes a set of cutouts for the manufacture of a box, characterized in that it comprises two cutouts respectively formed each by a flap or a central panel and by two flaps or side panels, namely a first cut intended to form a tray and a second cut intended to form an upper part of the box, said cutouts being able to be joined together by their respective flaps and side panels only by means of at least two precut side portions belonging to one of the cutouts and suitable for being glued to the other cutout. Advantageously, the central flap of the first cut comprises a central flap in the extension of said bottom provided with two pre-cut bottom portions, and the side flaps of the first cut each include a lateral flap suitable for being glued respectively to said said

precut portions of the bottom.

  Also advantageously the central panel of the second cutout comprises a central flap in the extension of said panel provided with two precut portions of cover and the side panels of the second cutout each comprise a lateral flap suitable for being glued respectively to

  said precut lid portions.

  In an advantageous embodiment, the first cut and the second cut each comprise a set of one or more flaps, said sets being respectively connected to the shutters and panels

  corresponding with pre-cut fold lines.

  The term “pre-cut fold line” means in particular a partially cut fold line,

  which only holds by a few attachment points.

  In another advantageous embodiment, the first cut includes three precut flaps and the second cut at least four panels, one of which has a flap connected to said panel intended to form the bottom of the box by a precut fold line. The invention also provides a method of opening a box with a polygonal section formed from two cutouts of corrugated sheet material, namely a first cut capable of forming a display tray and a second cut capable of forming the upper part of the box, said box being filled with rigid or semi-rigid products, characterized in that: the cutouts being only joined together by one or more pre-cut portions, or one or more bonding points, the tray is manually detached from the upper part of the body by simple pulling at the level of the precut parts, or bonding points, - the vertical transverse wall of the bottom of the tray is separated from the upper part and / or the longitudinal vertical walls of the tray, - pull the tray horizontally to release the products on top, - then pull the part horizontally ie superior to fully release the products it contains. In other words we pull the tray under the very feet of the products that will be able to stay

alone on the shelf.

  Advantageously the pull-ups are done on the same side. The invention also provides a method of opening a case according to the embodiments described above where the upper part and the tray are removed by pulling them successively and horizontally, above and below the

products contained in the case.

  - Figure 21 is a side view of a mechanical operating diagram showing the different steps of an embodiment of the box forming method according to the embodiment of

  the invention more particularly described here.

  In the following description, we will use both

  as possible the same reference numbers to designate the same or similar elements. Figures 1 to 3 show a box 1 formed from sheet material of cardboard or corrugated cardboard, for example double-sided corrugated cardboard of thickness 3 mm or less, for example less than

2 mm thick.

  The body 1 comprises two elements 2 and 3 which can be manually separated from each other, namely a first element 2 forming a display tray and a second element 3 forming the upper part of the body, the first element 2 being formed from '' a first cut 2 and the second element to

  from a second cut 3 (see figure 2).

  The first blank 2 comprises a series of three flaps, namely a central rectangular flap 4 forming the bottom of the tray connected laterally by first fold lines 5 parallel to each other with two side flaps 6 whose base is formed by the lines of folding 5, and going

  constitute two side walls of the body 1.

  The side flaps 6 comprise two substantially rectangular parts 6 'and 6' 'of different heights. According to this embodiment of the invention, each side flap 6 of the first cut comprises substantially in the middle of the flap, a precut portion 7, for example rectangular, for example 3 cm by 2 cm, the width of which is equal to the difference of height between the parts 6 'and 6' 'and which have two adjacent sides 8 and 9 free, and the two opposite sides 8' and 9 'connected to the shutter by two pre-cut lines easily torn from the rest of the shutter by traction perpendicular to the plane

of the wall.

  The flaps 4, 6 comprise two sets of rectangular transverse flaps 10 and 11 located on either side of said flaps to which they are connected by second fold lines 12, perpendicular to the first fold lines 5, which form once glued on each other

  two transverse side walls.

  The set of flaps 10 can for example form a handle 10 ′, the central flap being pierced with a gripping recess with folding for reinforcement. More specifically, the set of flaps 11 comprises a central rectangular flap 13 and two lateral flaps 14, rectangular of the same height as the

part 6 'of the side flaps 6.

  The central flap 13 comprises at each of its ends, two precut portions 15, for example in a closed line, for example square, which tear off and remain glued to the external face of the lateral flap 14, leaving two corresponding recesses 16, when '' pull the flap 13 according to the

arrow 17.

  The flap 13 can thus be placed entirely flat, without excess thickness of cardboard, in the

extension of the bottom flap 4.

  The second blank 3 comprises three panels, namely a rectangular central panel 18 forming the upper face of the upper part of the body, connected laterally by third fold lines 19 to two side panels

identical 20 rectangular.

  The panels 20 are secured to the corresponding side flaps, by being glued to the face

  internal of the precut portions 7.

  The panels 18, 20 have two sets of flaps

  21 and 22 respectively located on either side.

  The set 21 comprises, in the same way as the set 11 of the tray, a rectangular central flap 23 and two lateral flaps 24, rectangular as well

height than the body.

  The central flap 23 has at each of its ends two pre-cut portions 25, for example square, suitable for being glued to the external face of the lateral flaps 24, leaving two corresponding recesses 26 when the flaps are pulled according to

arrow 27.

  Such a box authorizes disbursement only by horizontal movements (arrows F and F ') of the tray and of the upper part (see FIG. 3), only the products 29 contained in the box remaining on the shelves or the presentation support of the

shop.

  Figure 4 shows the second blank 3 flat.

  FIGS. 5A and 5B show a variant of first cut 28 according to the invention, each side flap 29 of which comprises two precut portions 30 and 31 stepped, in the form of a diamond, of the type of that described with reference to FIGS. 1 to 3, by example to one third and two thirds of the length of the side flap, each of the precut portions thus comprising two free adjacent sides, towards the

bottom of the tray.

  FIGS. 6A and 6B give another variant of first cut 32, each side flap 33 of which comprises a precut portion 34, constituted by a rectangular part connected to the flap on three sides 35 by precut lines and free on the fourth 36 directed towards the bottom face 37 of the tray. More specifically, the flap comprises two rectangular parts of different heights, namely an upper part 38, one side part of which has the

  pre-cut portion, and a lower portion 39.

  FIG. 7 shows a box 40 provided with a tray 2 according to the embodiment described in

reference to figure 1.

  The upper part 41 is here formed of a bellows cutout. This embodiment will be more fully described with reference to FIGS. 16A to 17. FIGS. 8, 9 of the box and 10, 11 of cutouts show a box 42 comprising a tray 43 formed by a first cutout comprising two lateral flaps 44, each provided of two pre-cut portions 45 and 46, rectangular or substantially rectangular, one of which 45 is located at one end of the tray and is free on three sides and the other 46 is free on two sides and

  similar to the precut portions 7 or 31.

  The tray comprises a first set of flaps 47, namely two lateral flaps (not shown), glued to the central lateral flap 48 and / or a single

central side flap 48.

  The flap or flaps are connected to the corresponding flaps by pre-cut fold lines 49. Similarly, the second cutout 50 comprises three rectangular flaps 51 and 52 connected to the corresponding panels by precut fold lines 53. A gripping orifice 54 is provided at the fold line with the central panel, which allows, when the body is closed and glued, tear off in one piece the entire front of the

body according to arrow 55.

  The tray, for example which can be caught on the other side by the handle 56, will therefore be able to be removed as previously described, then the upper part, which can be grasped by the lower flap part located on the other side of the first

tear-away game.

  The horizontal lines of adhesive have been shown in FIGS. 8 and 9, the flap 48 being glued to the vertical flaps 52, just like the central flap

Panel 51.

  The precut portion 45 is in turn provided and glued far in front of the tray, which prevents yawning in the absence of side flaps which usually retain the tray in the

good position.

  Figures 12 to 15 show another mode of

embodiment according to the invention.

  FIG. 13 shows a first cutout 43 identical to that described with reference to FIG. 10. The second cutout 59 (see FIG. 12) comprises four rectangular panels 60 connected to each other by third fold lines 61, 61 ' , parallel and a set of rectangular flaps 62, 63, 64, 65, identical two by two, one of which (63) is provided to come in front of the packaging and is connected to the adjacent flap 60 by a

fold line 66 precut.

  Said adjacent flap is itself connected to its adjacent flaps by fold lines

precut 61 '.

  Here again, the front face formed by the panel 60 glued at the bottom to the central flap 48 of the flap, for example by gluing lines 68, can be removed entirely according to the arrows 69, taking into account the fold lines or precut edges 49,

66 and 61 '.

  Figures 16A to 16F and 17 show a box 70

  and a set of corresponding cutouts 71.

  The assembly comprises a first cut 72 provided with a rectangular main flap connected to two lateral flaps 74 symmetrical with respect to the longitudinal axis 75 of said cut, comprising by

  example two parts of different heights.

  Each side flap 74 is provided with a precut portion 76, for example in the form of a diamond and placed at the open edge of the periphery of the side flap 74, for example at the junction between the two parts of different heights,

  substantially in the center of the corresponding flap.

  The second blank 77 comprises three panels, namely a rectangular central panel 78, and two rectangular side panels 79, symmetrical with respect to the longitudinal axis 80 of the

cutting.

  Each panel has on both sides a

rectangular flap.

  More specifically, the side panels 79 comprise on one side rectangular flaps 81 and on the other side of rectangular flaps 82 with bellows each comprising a fold line 83 starting at 45 of the third fold line 84 outwards from of the junction between third line 84 and fourth line 85 of junction between

flaps and panels.

  The flaps 82 are also connected to the rectangular flap 86 of the central panel by a line of

folding 84.

  When the box is opened, it is therefore possible (see FIGS. 16B and 16C) to put the bellows flaps 82 in the form of a tunnel, with the flap 86 of the central panel 78, the small flaps 87 of the tray having discarded, which allows the lateral exit of products 88 by pulling horizontally on the upper part as

  indicated by arrow 89 in Figure 16E.

  FIGS. 18A to 19 show a box 90 of the type described with reference to FIGS. 16A to 17, here again unpackable only by extraction

horizontal (arrows 91 and 92).

  The first cutout 93 has a central flap 94, for example rectangular, and two symmetrical side flaps with respect to the longitudinal axis 96 of the

central pane.

  The central flap 94 comprises two transverse flaps 97, one of which includes a rectangular orifice 98, one edge of which coincides with the second fold line 99, forming teardown handles, and the other is for example devoid of

handle.

  The side flaps 95 are in turn provided by

  example of small rectangular side flaps 100.

  The side flaps also each have two precut portions 101, symmetrical with respect to the transverse axis 102 of the cutout, substantially in the shape of a triangle or trapezoid whose large base coincides with the second fold line 103, precut, of junction with the small adjacent flap 100, and one side starts at an angle from the junctions between the second and first fold lines. The central part 106 of the side flap is then of substantially isosceles trapezoidal shape, with a large base merging with the first fold lines 105 and a small base merging with the edge.

external device of the shutter.

  The upper part 107 of the body consists of a second cut 107 similar to the second cut 77 described with reference to

Figures 16A to 17.

  The portions 108 are identical with, and constitute the bonding spaces of the precut portions 101 which remain integral with the upper part (cf. FIGS. 18C and 18D) after the trapezoidal parts 106 of the

tray 109 (see figure 24B).

  FIG. 20 shows in perspective a view of a part 110 of a machine according to an embodiment

of the invention.

  More specifically, the machine comprises a support frame (not shown), a first assembly 111 for feeding the blanks 112 intended to form the tray, and a second assembly 113 for feeding the blanks 114 intended to form the part

  upper of the packaging according to the invention.

  These power packs are known in themselves

  same and make it possible to grasp the cutouts one by one by means of suction cups and then to tilt them onto a platform 115 on which the set of cutouts according to the invention is formed. More specifically, with reference to FIGS. 20 and 21, the lower cutout 112 is first of all flattened after extraction from the supply assembly

concerned.

  Then a gluing of the precut portions is carried out and the second cut 114 intended to form the upper part is then taken by the tilting suction feed system 113 to be placed precisely, then applied (press 116) to the first cut 112 which thus becomes united by bonding only through a

pre-cut portion.

  Then all the cutouts thus formed are moved horizontally (see FIG. 21) by means of transfer means 117, for example constituted by belts 118 in noria, under a parallelepiped mandrel 118 ′, for example

some distance from the latter.

  During transfer the end flaps are glued by means 119 of the glue gun type

  "hot melt", vertical injection.

  Then the central flap of the first cut (for example) is put under pressure on the mandrel in a manner known per se, for example by a plate 119 ′, as described with reference to the method and to the device

  described in patent EP 0 468 860.

  Similarly, the set of blanks is then wound around the mandrel by means of a tilting arm system (not shown) and the shutters and / or panels of the blanks are applied under pressure by means of push plate 120 on the mandrel 118 ', so that the body is

partly formed.

  Simultaneously, the flaps intended to form a lateral side of the whole of the formed box are applied to the bottom of the mandrel via

pusher cylinders 121.

  Once the box thus formed, it is ejected to form a side-fillable box according to the embodiment more particularly described here. We will now describe, in particular with reference to FIG. 21, the steps of the method according to the embodiment of box forming according to the embodiment of the invention more particularly

described here.

  The cuts are placed in the stores of

  storage composed of belt conveyors.

  The first bottom cutout (tray) and the second body cutout (upper part) are

then unstacked.

  Then there is positioning of the second cut between a pusher and movable stops (not

represented).

  The second cut is then transferred to a bottom stop and is then placed under the first cut by a connecting rod / crank system (not shown). During this transfer, the junction zone, i.e. the first precut portion, is glued

Above.

  There is then pressurization at the level of the

  junction and release of the stops.

  The transfer of the set of cutouts is then carried out under the mandrel 118 'During this transfer the set of cutouts finishes being glued on the flaps and on the second

pre-cut portion of junction.

  Then, the body is put into volume by mounting the wrapping arms, pressurizing the lower tacker, pre-folding of the outer junction panel of the first cut on the second cut, then simultaneous folding of all of the longitudinal flaps, finally folding and pressurizing the transverse flaps and the junction panel. The body is thus placed in volume with an inverted fold. Finally, the packaging thus formed is ejected, for example by a jack located at

inside the chuck.

  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

belts).

  The accuracy of these types of magazine is then ensured by reciprocal type settings, that is to say allowing the setting of the pick-up area.

depending on the removal position.

  This type of magazine by unstacking from above is also applicable on any type of coating, including around the product itself ("wrapp technique

  around "in Anglo-Saxon terminology).

  We will now describe the method of opening a case according to three advantageous embodiments of the invention, with reference to Figures 1

at 3, 8 and 9 and 18A to 18D.

  In the first case of figures (Figures 1 to 3), the operator starts by tearing off the flaps 13 and 23, according to arrows 17 and 27, then spreads the flaps 24, thus completely freeing the face 29 of the products, and putting at flat without extra thickness of

cardboard flap 13.

  Then the operator makes the precut portions yield by light traction perpendicular to the walls (for example by spreading with the thumbs), the precut portions then remain glued on the upper part. The tray is then fully

  released and detached from said upper part.

  The tray 2 is then pulled under the feet of the products, horizontally (arrow F), the flaps

  14, free, escaping from the sides.

  Then the upper part 3, the side closed by the flaps 23 and 24 is also entirely retractable and separated from the products, is in turn pulled horizontally (arrow F '), for example by a handle (not shown) on the rear face. from the upper part, on the same side (for example the front face of a department store shelf) as the arrow F. In the embodiment described with reference to FIGS. 8 and 9, the operator tears off at once the entire front of the box, this being connected to the rest of the packaging both at the level of the tray and at the level of the upper part

  only by pre-cut fold lines.

  Then the side flaps of the tray are separated with the thumbs, the portions

  pre-cut remains glued to the side panels.

  The tray is then pulled under the product by

through the handle 56.

  Finally the upper part is also pulled horizontally, for example using a recess

practiced, in the back side.

  In the embodiment of FIGS. 16A to 16F, the tray is open in the lower part, then the bellows flaps 86 are open, the tray is pulled horizontally, then the upper part and the products 88 are thus released, As it goes from itself 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 variants, in particular those where the boxes are obtained by other methods, such as those where the two cutouts are folded and glued flat one on top of the other, or even where the cutouts are placed tunnel of said set already glued by

  through said precut portions.
