Definitions
- Cardboard on the contrary, can only be shaped by bending or folding and only conforms at developable volumes, c that is to say geometrically reducible to a plane.
- plastics are more economical than cardboard provided have a low thickness. It is practically impossible, at present, to produce plastic articles of packaging having the strength and the appearance of cardboard.
- the present invention provides a new solution by which it is possible to achieve in cardboard, or similar material, container components that have a cost price reasonable, while offering customers qualities of solidity and aesthetic presentation excellent.
- the invention relates to a process for obtaining components for containers of cardboard or similar material, of the type according to which elements are created in a blank by pre-cutting lines and by creasing other lines, characterized in that one places the blank precut and grooved opposite a shaping device comprising a concave matrix on the one hand and a convex stamper on the other hand which respectively comprise as many cells and as many punches as there are elements, the blank shaped in the matrix by fracturing the blank along the precut lines and by folding along the crease lines in order to form elements each having a concave part and a convex part formed by side walls and by a bottom, keeps the blank in shape, in particular by bonding close-together parts, the matrix is separated from the stamper and the blank is removed.
- L also relates to a component for a container made of cardboard or the like, of the type formed by part of a blank cut, creased, folded, shaped and maintained in volume, characterized in that it includes at least one element in volume and l other by a flat frame, l volume element with at least one periphery d a bottom as well as side walls integral with the frame.
- Figure 1 is a partial schematic view of a blank conforming to invention, crossed by openings, marked with precut lines and crease lines.
- Figure 2 is a partial schematic view of a second blank conforming to l invention, crossed by openings through which elements from the blank of Figure 1 must be placed during their forming.
- Figure 3 is a partial schematic sectional view illustrating the forming of an item in accordance with invention and showing the blanks of Figures 1 and 2 placed in position between a cell of the matrix and a punch of the stamper, before forming.
- Figure 4 is a partial schematic sectional view illustrating the forming of an item in accordance with invention and showing the blanks of Figures 1 and 2 after forming the element in the alveolus by the punch.
- Figure 5 is a schematic plan view showing an isolated planar element, c that is to say untrained, which does not correspond to the reality of the process in accordance with invention but makes it possible to discern its different parts better than in FIG. 1.
- Figure 6 is a schematic view showing the two blanks of Figures 1 and 2 after forming of the elements, these appearing by their convex part.
- Figure 7 is a schematic view showing the two blanks of Figures 1 and 2 after forming of the elements, these appearing by their concave part, their fixing lugs then being visible.
- Figure 8 is a schematic view similar to that of Figure 7 and illustrating a variant of the invention according to which the second blank has shims.
- Figure 9 is a partial schematic sectional view showing the two blanks of Figures 1 and 2 after forming the elements (only one is shown) and establishment of a panel fixed to the blanks and covering the concave part of the elements.
- Figure 10 is a schematic view similar to that of Figure 9 and showing the presence of shims, the panel being applied both to the legs of the elements and to the shims.
- Figure 11 is a schematic view illustrating a variant of the invention according to which the panel is formed by a folded part of the second blank.
- Figure 12 is a partial schematic view of a blank conforming to invention, crossed by openings, marked with pre-cut lines and crease lines, in view of the simultaneous obtaining of a plurality of independent trays.
- Figure 13 is a schematic view in light perspective, showing the top of a tray conforming to the invention maintained in volume by gluing tabs provided at the ends of a rim and obtained from the blank of FIG. 12.
- Figure 14 is a schematic view in light perspective similar to that of the Figure 13 and showing the same tray but from below it.
- FIG. 15 is a schematic view at the end of the container of FIG. 13.
- Figure 16 is a partial schematic view of a blank conforming to invention, crossed by openings, marked with pre-cut lines and crease lines, in view of the simultaneous obtaining of a plurality of independent trays, according to an embodiment which is similar to, but different from, that of FIGS. 12 to 15.
- Figure 17 is a schematic view in light perspective, showing the top of a tray conforming to the invention maintained in volume by a single piece frame, derived from a second blank (not shown).
- FIG. 18 is a schematic view in light perspective similar to that of the Figure 17 and showing the same tray but from below it.
- FIG. 19 is a schematic end view of the tray of FIG. 17.
- Figure 20 is a partial schematic view of a blank conforming to invention, according to a particular embodiment, traversed by openings, marked with precut lines and crease lines.
- Figure 21 is a partial schematic view of a second blank conforming to l invention, according to the same embodiment as that of FIG. 20, also crossed by openings and having elements to be engaged in the openings of the blank of Figure 20 during the simultaneous forming of the two blanks.
- Figure 22 is a partial schematic view showing the result of the combination blanks in Figures 20 and 21.
- the process according to l invention allows obtain cardboard or other similar material from one blank.
- the pre-cut lines are broken by pulling parallel to the plane of the blank, while the push s exercises perpendicular to this same plane.
- Volume maintenance can be obtained in various ways, in particular by bonding of close together legs during the forming of the elements.
- the blank 1 is marked with precut lines 2 in solid lines and crease lines 3 in dotted lines.
- some of the precut lines form the sides of polygons and create openings 4 revealing the dark background on which the blank 1 is supposed to be applied.
- the elements have substantially the shape of a cross of Saint Andrew whose branches are divided by lines of creasing to facilitate the folding of the parts that they determine and which are, for each element: a central bottom 5, four side walls 6 and four legs 7.
- the elements hold to each other by the adjacent tabs 7, so that the blank the whole can be handled as a whole.
- each element is composed of the bottom 5, four walls 6 straightened perpendicular to the bottom 5 and four legs 7 folded down relative to the walls 6 to be parallel to the plane of the bottom 5.
- the walls 6 are not connected between them, the legs 7 either.
- FIG. 2 To maintain in volume all the elements from the blank 1, in order to form a complete component, a second blank 10 is used (FIG. 2) which is crossed by as many openings 11 qu there is some elements on the blank 1.
- the openings 11 have dimensions, shapes and positions which correspond to those of the elements formed. In d in other words, the openings 11 are arranged like the bottoms 5 of the elements.
- a shaper ( Figures 3 and 4) which includes on the one hand a stamper 20 having as many punches 21 as there is some elements and, d on the other hand, a matrix 30 having as many alveoli 31 qu there are punches 21, and therefore d elements.
- the bottom 5 exerts a traction on the walls 6 and these exert a leg traction 7.
- the pulls due to the corresponding punch 21 are contrary, they cause the break of the precut lines 2, which separates the elements from each other and makes them all independent.
- the walls 6 can therefore follow the bottom 5.
- the punch 21 has housings 22 whose depth is substantially equal to l thickness of the cardboard constituting the first blank 1, in order to be able to contain the tabs 7 and press them against the second blank 10 (FIG. 4).
- the second blank 10 encloses each element by its periphery determined by the walls 6, straightened from the bottom 5 perpendicularly to it.
- This fixing can be obtained by gluing, in particular by providing an adhesive either under the first blank 1, or on the second blank 10. But, given the relative sliding movement of the two blanks l one on l other when forming the elements, avoid irregular bonding and the one can, for example, provide a dry thermoactive adhesive which n is made effective that after forming the elements, by heating the punch, which is within the reach of tradesman.
- the finished component is presented on one side as shown in FIG. 6 and by its other face as shown in FIG. 7.
- the face ⁇ useful ⁇ is, here, that which presents the convex part of the elements because the elements in relief are used as wedging for objects to be immobilized in a container of any known type such as a box, a box or a case. There is shown in dotted lines in FIG. 6 such an object blocked by four elements.
- the component On its other side, the component has the concave part of the elements and the legs 7 glued to the second blank 10.
- the panel 40 is applied to a surface d as much more irregular as the cardboard constituting the first blank 1 is thicker, which can cause unsightly undulations of the panel 40, as we shown in Figure 9.
- the whole from the first blank 1 obviously has the same thickness as the legs 7 and largely compensates for the spaces left by the withdrawal of the bottoms 5 and of the walls lateral 6 during the forming of the elements.
- the panel 40 then has little or no d ripples, as we evoked in Figure 10.
- the panel 40 covers the opening of the concave part of the elements, which supposes that the we consider their convex part as the only useful part, which is the case when l we use the component as calibration (figure 6).
- the panel 40 must be crossed d openings centered on the elements in order to hide the legs 7 while leaving free the access to interior of the elements.
- the panel 40 is an independent panel, attached and fixed to blanks 1 and 10.
- FIG. 11 an alternative embodiment of the covering panel has been shown, which consists in providing a second blank 10 of approximately double length in order to have two parts 10 a and 10 b separated by a transverse fold line 10 c .
- the second blank 10 is then folded along line 10 c , as indicated by the arrow, to be applied to the first blank 1 and to the back of its part 10 a .
- Creasing lines 53 determine, for the tray to result from each blank, bottom 54 and opposite side walls 55 and 56, while crease lines 57 determine opposite segments 58 and 59 to determine a frame as we will describe below.
- the blanks are shaped.
- the breaking of the precut lines 51 and 52 is done by traction parallel to the plane of the blank 50, while the thrust of the punches s exercises perpendicular to this same plane.
- Maintaining volume is obtained by bonding neighboring segments 58 and 59 close together during the formation of the trays, or more generally by any means of assembly and, in particular, by thermoadhesion.
- the blank 50 Before passing to the shaper, the blank 50 therefore has a plurality of blanks fixed to each other and after passing through the shaper, individual and independent trays from each other are obtained which are each presented as shown in FIGS. 13 to 15.
- This covering is used to fix the segments 58 and 59 together, in particular by collage.
- FIG. 16 an element according to the invention consisting of a simple tray, derived from a blank 60 cut and optionally printed, shown in FIG. 16.
- Creasing lines 63 determine, for the tray to result from each blank, bottom 64 and opposite side walls 65 and 66, while creasing lines 67 determine the gluing tabs 68 and 69 which must cooperate with a frame as will be seen. describe below.
- the blanks are shaped.
- the breaking of the precut lines 61 and 62 is done by traction parallel to the plane of the blank 60, while the thrust of the punches s exercises perpendicular to this same plane.
- Maintaining volume is obtained, here, by bonding tabs 68 and 69, folded during the formation of the trays, against a frame 70 from a second blank (not shown).
- This second blank includes as many frames as there is some blanks of trays on the blank 60.
- the central part of each frame 70 is hollowed out and they hold to each other by their edges.
- the two blanks Before passing to the conformator, the two blanks are superimposed and during the forming of the blanks of trays, they penetrate into the hollowed-out central part of the frame 70, the legs 68 and 69 s each applying against the one of the sides of the frame and being fixed thereto, in particular by simultaneous bonding.
- the frames are not separated from each other automatically since they do not undergo any tractive effort in their plane since they undergo no training, no deformation.
- This plate is obtained in a single forming operation, from two blanks coordinated.
- FIG 20 we see a first blank 80, having a plurality of blanks and notched, for this purpose, with parallel cut lines 8 and cut lines 82 perpendicular to the previous ones and connected by an oblique line 83, giving this set of three lines 82-83 a shape substantially in ⁇ Z ⁇ .
- the two blanks 80 and 90 are superimposed, the frames 86 and 94 respectively of which overlap perfectly, as well as the perpendicular segments which join their sides, so that the walls 95 and the flaps 96 are placed on and against the walls 87 and the flaps 88.
- the thrust of the conformator has the effect of act simultaneously on the two blanks, so that the walls 95 fold ⁇ down ⁇ along the outer lines 93 and push the walls 87 which fold in the same way along the lines 84, while the flaps 96 separate along line 92, remain parallel to themselves thanks to interior lines 93 and push the flaps 88. These separate along line Z 82-83-82 and remain parallel to themselves thanks to lines 85 .
- each cell n is therefore not integral, but has a central opening 100.
- This embodiment can be adopted to produce a honeycomb tray intended for wedging and for the presentation of small solid objects which are compatible with the presence of the opening 100 of the bottom of each cell.
- the invention finds many applications, both in food and non-food products, especially when the we want to obtain both an efficient setting and a good presentation.
