Description

[Detailed description of the invention] laminate products This invention applies to laminated products, especially for use as props for promotional or entertainment purposes. Concerning the discovery of special applications for low-cost headgear.

Advertising and promotional products, including promotional headgear, must be made of cardboard. This is a well-known fact. Cardboard has advertising or advertising on the surface that is exposed to the outside during use. Materials related to advertising are printed. An example of such a product is a flat plate of cardboard. A simple device with an opening in the center through which the user pokes his or her head. There is a headgear. This hat has no peaks and is attached to the wearer's head by the brim of the hat. circle. This type of headgear attracts attention, so when the hat is not in use, protruding into the central opening, but when the hat is in use, the central opening of the hat With the user's head more protruding, the logo carrier can be bent upright. You may also add a.

Products of this type have the disadvantage of being relatively delicate and easily broken. logo The carrier is therefore unable to perform its function for any meaningful length of time.

In making the present invention, cardboard is used as a foamable polymer in the manufacture of articles such as those described above. By replacing it with It is recognized that However, promotional materials such as advertising text and other decorations It is not an easy task to decorate the surface of a foam product with a suitable replacement material. A problem occurs. Suitable for manufacturing fun hats (funny hats) as mentioned above. These types of foamable products rely on the use of open cell foam materials. open on cell foam material products that are clear and detailed enough to be used and long-lasting. It is impossible to perform such direct printing.

By embodying low-cost promotional or entertainment props, especially: Made of laminate, which can be used for example as promotional or entertainment headgear product, maintain its beauty, and/or be used for a significant period of time. The purpose of this invention is to provide a method for manufacturing the above-mentioned laminate products, which is possible. It is the purpose of light.

Embodiments of the invention can be manufactured in large numbers at a moderate cost and are similar in cost to products. The user's considerably rougher and/or longer movements compared to what was previously possible It is strong enough to withstand rough handling (L) while providing a pleasant appearance.

According to the invention, it has a body of foam material and a printed film adhered to its surface. such as those used in promotional or entertainment props that have foam material products that Laminated products are supplied.

The foam material may include known polymeric foam materials. Preferably 1′! oven cell Contains mold foam material.

Printing films contain plastic materials such as polyethylene or polypropylene. may have.

Molding and decorating from foam materials, especially open cell foam materials, on a low budget. Creating a unique product means printing it! Easy to move during cutting It is practically difficult, including the fact that it is difficult to do so.

However, even from printing film to foam material, oven cell foam material, etc. something that can be applied and thereby solve a set of problems was discovered here. In more detail, related issues and their solutions are as follows: It is as follows.

As mentioned above, foam materials, and oven cell foam materials in particular, are suitable for direct printing. It is very difficult to cut out a predetermined shape precisely. It has a movable structure.

A feature of the invention is that the use of adhesive film not only serves as a carrier for printing, but also for cutting. The reason is that it is also used to fix the foam material.

However, adhering a suitable film to the surface of oven cell foam is easy. It's not a simple thing. Adhesives will not stick to the film, which is a very flat surface; Therefore, it is not enough to apply adhesive-coated films to foam materials. I understand.

To improve the adhesion of the adhesive to the film, the surface of the film can be e.g. flame treated. Or it can be modified by corona discharge treatment.

Another problem is the unsatisfactory lamination of the film onto the surface of the oven cell foam material. is in the process of achieving nate. No wrinkles in the film to achieve a satisfactory lamination. It turns out that the important factor in achieving this is the thickness of the film to be bonded. It was. This will be shown in more detail later.

The printing ink used to make the printed film reacts with the film, making it It was discovered that it made it brittle, which created yet another problem. This thing lasts In use, the film and/or the design printed on it may be damaged. This leads to the problem that the Many inks and printing processes are too costly to use, or itself is inflexible or the ink is inflexible. Does not adhere to film surface.

These problems prevent the ink from peeling off from the film surface during the manufacturing process. For this purpose, ink for curved surface printing (flexographic 1nk) and flexible photogravure or gravure printing, for example by flame treatment or coating as described above. By using it with a film that has a film surface that has been subjected to a discharge treatment, Basically resolved.

The oven cell foam material to which the printing film is laminated is made of polyethylene, May contain one of several materials including urethane and polyester. However, polyethylene foam material has been found to be preferable due to cost considerations.

The manufacturing process generally includes surface treatment of polymeric films, especially polyethylene films. This is done by flame treatment or corona discharge treatment, for example. After printing on the film, it is laminated using known common lamination processes. Laminate the printed film onto the roll of oven cell foam material in the opening equipment.

In the laminating process, adhesives are used both in foam and in films. has been found to be applied to and used with any solvent-based adhesive. , the film is then attached to the surface of the foam material.

When printed laminate foam material is used to make fan hats , a thickness of about 7 mm was found to be suitable. This means that the amount of material used This cap is relatively small and avoids unnecessary cost and volume. A hat that is stiff enough to stand up in one part so that it is clearly visible when the child is wearing it. is being produced. The thickness of the foam material is preferably in the range of 5 to 1Q mm, preferably 7 mm. It turned out to be optimal.

As mentioned above, the thickness of the film determines whether the lamination process is successful or not. impact on cancer. Even thin films with a thickness of 25 to 45 microns are sufficient. However, it is known that the filament is a little thicker, for example up to 100 microns. or more preferably a 60 to 70 micron film is laminated. Mechanically easy to handle in the mining process. This is true for film and foam materials. This makes it easy to reach a high alignment and relative tension between the two.

The invention will now be described in detail by way of example only with reference to the accompanying figures, in which: FIG. as below be: Figure shows a plan view of a fan hat made according to an embodiment of the present invention. vinegar; Figure 2) shows where the fan hat shown in 'igurel is used. show; Figure 3 shows the printing film being applied onto the surface of the oven cell foam strip. Figure shows a schematic diagram of the laminating process; 4 is a diagram of the overlapping part on the line A-A of the figure, seen in the direction indicated by the arrow. Shown: And Figure 5 shows the laminate before it was cut into van hats. A portion of the applied sheet is shown.

See Figures 2 and 4, Fans Made According to Embodiments of the Invention. The hat is made of oven cell foam material 6 with a printed film 5 on its upper surface. It has a flat panel 1. Composite panel 1 is a scallop ed) having an opening 2 in its interior with a mold edge. Opening 2 is an opening from its edge. It has a "cut-out" 3 extending into the center of the. This hat is placed on the user's head. When the "cut-out" 3 is pushed upwards and straight into a visible position, stand.

The scalloped edge of opening 2 merely provides grip to the wearer's head. and can be replaced with a different shaped opening, such as a smooth-edged opening or a tooth-shaped opening. You can get it.

See Figure 2, the “cut-out” 3 is made of foam so that it can stand on its own when in use. It is clearly seen that the material panel 1 must have a certain thickness. Indicated In a specific example, the oven cell foam material has a thickness of 7 mm.

See Figure 3, the fan hat is made using a laminating machine.

Roll 4 of oven cell foam material is transferred to 31.32 sets of laminating rollers. There, it meets the printing film 33 and is laminated. printing film 3 3 is supplied from a roll 30, and includes a tension adjustment roller 34 and an adhesive supply roller. 35 to the laminating rollers 31, 32. laminating roller 32. In 33, the adhesive covering the surface of the printed film is produced in an oven cell. The adhesive is then applied to the foam material and the adhesive is cured to form a laminate product 38 with a variety of foam materials. It is compressed or cut into a core. This common type of laminate The engineering process is known and therefore the elements of the device are also known. for example, The adhesive supply roller 35 is applied to the roller 35 and then to the surface of the printing film 33. It has a bath 36 for supplying adhesive. Typically, the adhesive supply roller 35 is, for example, It can be removed from the printing film 33 and cannot be loaded or operated for maintenance. Ru.

The relative tension between film 33 and foam material 37 is important. If this is inappropriate The film may roll up during application or may be damaged during the laminating process. If the material is significantly denser than the foam material used, it will tend to cause the finished product to kink.

The tension is adjusted by a tension roller 34 which brings the tension it applies to a suitable value. can correct such deficiencies. Preferably a "banana" roller is used. this Such a roller has an outer surface that is slightly convex in cross section, which is similar to roller 33. The effect of spreading the film 33 outward toward the ears on the surface of and holding it flat has.

Adhesives for adhering films to products made of foam materials can be applied using known techniques, e.g. For example, the method used in the manufacture of carpet underlays and the use of solvent-based adhesives are disclosed in the present invention. It is appropriate for However virtually laminated onto open cell foam material There are certain problems with the use of possible printing films. Types of ink that can be used ( This should not destroy the flexibility and durability of the film to be laminated. ), the film must be treated to accept both ink and adhesive. There is a point. If the film is not treated, a film such as polyethylene film do not accept adhesives or printing inks well, and these will not adhere to the film. Otherwise, it will be removed very easily. Therefore, the film has a surface treatment. For example, corona discharge treatment to improve adhesion.

Corona discharge treatment slightly oxidizes the surface of the film, resulting in the formation of e.g. methyl groups. to increase the number of surface molecules. Such surface modification is caused by inks or adhesives. spread more tightly over the surface during subsequent printing and adhesive application processes, and and promote the formation of chemically strong bonds. Both factors improve adhesion Ru. In one embodiment of this technology, the film is coated with or without an insulating cover. A high-energy electrical corona discharge may be formed between the ground roller and the electrode. This is the way to do it. Suitable equipment is commercially available and is sufficient to generate a corona discharge. It operates from a normal mains voltage generating sufficient power at a high frequency. The film surface Subject to high-energy electrical and ionic bombardment, the intensity of which is adapted to the electrodes Usually controlled by adjusting the amount of electricity. Corona discharge treatment is described in the following document. Are listed: “Electrode Developments for Treating Advancement (by F.E.T. Blip and Karl-Heinz Mayer) , Paper, Film and Foil Converter, September 1988); “Alkacene Polyethylene”, Technical Service Note AlO3, No. 2nd edition (Polyolefins Group of ICI Plastics Divi Volume 32, “Printing of Polyethylene Film” series. ) After the corona discharge treatment, the polyethylene film is processed using known techniques such as flexog Print the desired decorative image on one side of the film by raffy or gravure printing. may be prepared and then fed into rolls. Then apply adhesive to the non-printing side of the film. and then oven cell foam in the laminating process described above. Glue to the material.

After lamination, a fan hat printed with the manufactured composite sheet 38 (interesting Hat) Cut to fit size 50. Four fan holes to achieve accurate cutting Each panel 52 includes a set of markers 50, each panel 52 having a marker 51. to print. A cutting machine (not shown) detects a marker 51 for each panel 52; Each marker 51 is precisely and precisely positioned with respect to the printed hatch 50 of the panel 52. let The cutting machine cuts out the outline of the van hat according to those prints. It may be aligned itself in order to

Although different types of films may be used in different thicknesses, polyethylene film The appropriate thickness of the lume is in the range of 25 to 45 microns, which allows for decorative cutting. The take-off section gives the oven cell foam material sufficient strength. However, as mentioned above To make it easier to match the tension between the film and the foam, the thickness is 6. Films having a diameter of 0 to 70 microns are more preferred.

We decided to use a combination of flexographic ink and polyethylene film. Approximately 6 different colors can be printed, making the photographic image reproducible. Ru. Either high or low density polyethylene film can be used; Film is preferred. These films may be transparent or colored.

Another material useful for use as a printing film is polypropylene. child Although it is more expensive than polyethylene, it has less elongation and therefore, e.g. physically easier to handle during the printing process.

The film used is printed on either side relative to the surface to be adhered to the foam material. You can leave it there. Or it can be reverse printed on the adhesive side (or in the final product). It may also be positively printed on the exposed surface. When printing in reverse, one side of the film Only one side of the film is coated with ink and adhesive, so only one side of the film can be corona discharged. This is a printed but non-adhesive film. is easier to feed onto the roll. Because the unprocessed side of the film is printed This is because a large amount of ink is not lifted up from the side. However, if positive If printing is adopted, the number of color prints where the background color is used can be reduced.

In reverse printing, the background must be printed, but in positive printing, the film itself Can be colored.

Does not significantly interfere with the printed film or adhesive and provides the printed film in the roll. Suitable types of ink that do not tend to lift a lot when dispensing are solvent resistant and wax-free. Contains comb-free laminating ink. This kind of ink is “Polaris Available from Company Collie Tuck Consolidated under the trademark 2.

Products according to the invention can be manufactured relatively cheaply and can be produced in large quantities, e.g. in batches of 10,000. Convenient to make to order and retains glossy coloration over long periods of time This makes it an excellent promotional material.
