Abstract

A decorative laminate for packaging is prepared by assembling 1) a base layer, 2) a heat-sealable layer and 3) a surface layer to provide the decoration, cutting out layers 2) and 3) to the required size and shape and heat sealing at least the edges of these layers to the base layer. The laminate formed may then be embossed.

Description

SPECIFICATION Method of production of a product such as a decoration card side The present invention relates to a method of production of a product such as a decoration card side or of production of a display stand or packaging, said product consisting of a support into which a decoration or a trimming element is fixed, having been cut out from a sheet of decoration or trimming material, of appropriate shape, the whole thus formed being possibly embossed or figured.
The invention also relates to products, particularly packagings, advertising items, display stands, etc. made according to the process of the invention.
It is already known to glue fabrics onto a great diversity of backings, particularly to glue a fabric which has been given a thermo-adhesive coating, onto cardboard to make display items, luxury packaging, intended in particular for the perfumery trade.
However, this known technique, though of great interest, suffers from a certain number of drawbacks.
To carry out this known technique it is necessary to have a sheet of decoration material (fabric, paper, metal foil, etc.) previously coated with a thermo-adhesive coating. This results in a very great rigidity. Indeed, the material has to be coated with the self-adhesive coating. This often requires outside intervention, away from the workshop processing the product. Moreover, this creates problems of stocks, ranges, etc., as each material used to produce the decoration material must be available in the form of a strip bearing the heatweldable layer.
At manufacturing stage proper, using such a strip, with a heat-weldable coating, is bound with difficulties particularly when the motif fitted with the decorative sheet comprises relatively substantial deformations. In other words, such motifs cannot be produced as the element sheet does not possess enough flexibility to follow the deformation progressively and the sheet teras or is deformed in unacceptable manner.
In addition, the edge of the decoration element or motif thus made often lacks definiteness, the threads of the fabric not being all properly cut. Thread ends may remain, impairing the overall appearance of the product.
The present invention aims at obviating the drawbacks of the known solutions and seeks to create a method making it possible to achieve products such as decorated card sides to produce display units, packagings, particu larly luxury packaging for the perfurmery trade and, generally, luxury products, imparting to the product a very high finish and clarity of production both with respect to the decorative element(s) inserted in the support and with regard to possibilities of deformation and particularly embossing of the product.
For the purpose the invention relates to a method of the above type, characterised in that: -a) the sheet of material for the decoration element is placed on the support, a layer of heat-weldable material being inserted in between the two; b) the decoration element is cut out of the sheet and layer while said element is crimped by heat sealing into the support by glueing the edge of the element to the support by the edge of the piece of heat-sealing material thus cut with the cutting tool.
c) at least a considerable part of the surface of the element is glued onto the backing by means of the heat sealing layer.
The method of the invention allows the use of a very wide range of materials as a sheet from which the decoration element is cut out.
There is no need to coat this sheet with heatweldable material,- all the more so as some relatively fragile materials do not accept such a heat-weldable layer.
Moreover, as the cut-out assembly made up of the piece constituting the decoration element and of another piece of corresponding shape supplied by the heat-weldable layer, is one unit, the connection of the piece and backing is effected only at the cut-out edge of the piece. As this edge is furthermore crimped in the backing, the slight depression caused by the crimping ensures a clear separation between the edge of the cut-out piece and the remaining part of the sheet. This edge is all the more clearly defined as any ends of threads in the case of a fabric or of fibres in the case of a material such as paper, protruding from the cutting edge, remain embedded in the crimping line. The whole of the picture is thus perfectly clearly defined.In addition, this preliminary fixing by crimping ensures the holding of the piece and allows, during the subsequent glueing stage, with embossing if need be, the free movement of the piece during embossing or figuring. This is all the more important as, at that time, the piece cut out from the decoration sheet, the piece cut out from the heat-weldable layer and the backing are in contact only along the crimping line. As throughout the embossing operation, until a short time before the end of the operation, the surface of the piece is not applied against the heat-weldable layer and against the backing, the relative shift allows compensating for local elongation due to local deformations more substantial in this or that part of the decoration element. This allows the avoidance of any tearing, even in the case of an embossing leading to complications or substantial deformation.Moreover, as the coating of heatweldable material can also move freely to a certain extent as it has not yet been applied under pressure against the backing and against the piece, it may also spread and prevent any tearing bringing about uneven glueing.
The product thus obtained exhibits perfect clearness of outline and shape of embossing.
Although in most cases it may be of interest to glue all the surface of the decoration element onto the backing it may be of interest sometimes to leave some parts unglued. For this, it will suffice to make cavities at the corresponding places in the bottom of the embossing die to avoid heat-welding at that point.
According to another characteristic of the invention the sheet of material in which the decoration element is made is fabric, paper, unwoven material, metal foil such as thin foil in a gold coated or silver coated ductile metal, etc.
The invention relates also to products made by this process and particularly all products for decoration, advertising and packaging constituted by backings, particularly cardboard sides.
The present invention will be described in greater detail against the attached drawings, wherein: Figure 1 is a partly sectioned diagrammatic view showing the first stage of the method of the invention; Figure 2 is a partly sectioned diagrammatic view showing the second stage of the method; Figure 3 is a partly sectioned diagrammatic view showing the third stage of the method; Figure 4 is a diagrammatic view showing the product obtained by the method of the invention.
The invention will be described hereinbelow within the framework of the making of a product such as decorative eiement, particularly a cardboard side for the production of a display unit or a packing constituted by a support onto which a decoration element cut out from a sheet of material has been fixed.
According to Fig. 1 one places of an support plate 1 forming part of the machine a support 2, e.g. a cardboard sheet, onto which it is intended to fix the decoration element.
Over said support 2 a sheet 3 of heat sealable or heat-weldable material is placed, and above this a sheet of material 4 from which it is intended to produce the decoration element to be fixed onto the backing 2.
This figure also shows the blade 5 mounted on the blade holder 6. Blade 5 is a heating blade to ensure heat-welding. On the other hand, the blade holder 6 may be cooled not to bring about glueing accidentally.
The support plate 1 is generally the plate of a press or an intermediate plate fixed to a press. This press also carries the support 6 fitted with a knife 5. Said knife is generally constituted by one or more steel blades such as the blades used in the technology of card making and of the cutting out of card sides, jig-saw puzzles, etc.
Support 2 used is a support of cardboard, paper or synthetic material. The thickness of this support has been deliberately exaggerated on the drawings, as has the thickness of layer 3 and of sheet 4.
Layer 3 is generally a non-woven sheet of fibres of heat-weldable or heat-sealing material unwound from a reel.
Sheet 4 is a sheet of material generally used for decoration, e.g. fabric, paper or metal foil, such as a gilt, silvered foil, aluminium foil, etc.
Though shown as sheets on Fig. 1, layer 3 and sheet 4 may be dispensed by reels which reel them off as needed.
Fig. 2 shows the end of the first stage of operation, i.e. when the decoration element has been cut out and crimped in support 2.
According to Fig. 2, the knife 5 and the knife-holder 6 are in raised position and have entrained with them in their upward movement the remainders 38 and 48 of the layer 3 and of the sheet 4 after cutting out the element 7 constituted by part 3A of the layer 3 inside the outline of the knife 5 and of part 3B formed inside knife 5 in the sheet of material 4D.
During its cutting motion the knife 5 effects not only the cutting out of parts 3A and 3B but also the crimping of the edge 8 of element 7 thus cut in the support 3. The depth of crimping has been considerably exaggerated in Fig. 2. It should be noted that knife 5 performs a triple role, that of cutting out element 7 (made up of parts 3A and 38), that of crimping the edge 8 of element 7 into support 2 and, finally, that of heat-sealing the edge 8 in support 2. Said heat-sealing is effected be means of the edge 9 of the part 3A in a heatweldable material.
Fig. 2 also shows that all the centre portions 3C, 3B are neither glued together nor glued to the support 2 as even if the knifeholder 6 comes in contact with the part 7 there is no heat-sealing but only crimping of the outline of the part of the motif to be embedded.
Fig. 3 shows the third stage of the method according to the invention. This third stage consists in giueing the element 7 on the support while ensuring the embossing, at least partial, of the support and of the element.
To that end, the assembly constituted by the support 2 in which the element 7 is crimped is arranged between a die 8 and a counter-die 9 having, one cavities 8A and 8B, and the other bosses 9A, 9B. Die 8, and possibly counter-die 9. are heated to ensure both the embossing or forming of the assembly 2-7, and the simultaneous glueing by heatwelding of part 4A of the element 7 on support 2 by means of the piece of heat-weldable material 3A.
Fig. 4 shows the result of the latter oper ation. The product obtained, such as an embossed side for making a luxury packaging, is still hooked to the counter-die 9. In this figure the part 4A constituting the decoration element 7 is glued to a support 2 and the layer of heat-sealing material has disappeared.
Generally, the thickness of the sheet constituting the decoration element 7 is small enough for the shape of the die 8 not to have to allow for its thickness, but solely for the thickness of the support 2 and for the deformation (embossing) to be made. It follows from this that part 7 is generally embedded in support 2 and is flush with the surface of the latter.
