Description

SAMPLE CARRIER, PREFERRED FOR A COSMETIC PRODUCT

The invention relates to a sample carrier, preferably for a cosmetic product,

Sample carriers for fragrances are known from US-A-5,391,420. The known sample carriers are provided on their underside with a pressure-sensitive adhesive (pressure-sensitive adhesive) with which they can be attached, for example, to one side of a magazine or magazine for advertising purposes. If desired, they can be separated from there. After separation, the pressure-sensitive adhesive retains its adhesive property, which means that the underside of the separated sample carrier remains sticky. As a rule, those addressed by advertising perceive this as annoying. Adhesive residues can also remain on the side of the magazine or the magazine, so that they stick together with their adjacent page after the sample carrier has been removed, which is also perceived by the reader of the magazine or the magazine as very unpleasant.

Against the background of the problems described, the invention has for its object to provide a way to easily attach a sample carrier, preferably for a cosmetic product, to a substrate, such as a magazine page, and to pull it off easily, without any adhesive residues remain neither on the magazine side nor on the sample holder.

To achieve the object, a sample carrier, preferably for a cosmetic product, is provided according to the invention, which can be connected or connected to a substrate via at least one connecting layer, the connection being separable along a separating surface between the sample carrier and the substrate, and to the Partition surface adjacent parts are not adhesive after separation.

While with conventional sample carriers for cosmetic products, pressure sensitive adhesive layer th and mostly siliconized separating layers are provided, the (releasable) connection between the sample carrier and the substrate (magazine) is realized in a surprising manner for the person skilled in the art with an adhesive-free material pairing.

To achieve this object, a method for attaching a sample carrier to a substrate is further provided, comprising the following steps: providing a sample carrier, on one side of which there is a connecting layer defining a separating surface and at least one auxiliary carrier which has at least one self-adhesive layer; Providing a substrate, pressing the sample carrier onto the substrate in such a way that a connection is established between the at least one auxiliary carrier and the substrate, after the sample carrier having been separated from the substrate being separated along the separating surface in such a way that in the region of the separating surface lying parts are not adhesive.

According to a further aspect of the invention, a method for attaching a sample carrier to a substrate is provided to achieve this object, comprising the following steps: providing a sample carrier, providing a substrate, applying a varnish or a printing ink to the sample carrier and / or the substrate, Press the sample carrier and substrate together at the location provided with lacquer or printing ink, harden the lacquer or printing ink.

Varnishes and printing inks are particularly suitable as materials for connecting layers that have sufficient adhesive strength, but still no longer have any stickiness after the adhesive connection has been torn open and feel completely dry.

UV-hardened lacquers or printing inks are particularly preferred.

Varnishes or printing inks are preferably used, which can be applied by means of screen printing, letterpress printing or flexographic printing. Lacquers or printing inks applied in particular by means of screen printing can be applied in a precisely defined thickness. After they have been applied in liquid or pasty form and placed between the two parts to be connected, they are hardened, as a result of which the two parts to be connected are connected to one another with sufficient strength. When one of the two parts is torn off mechanically, the lacquer layer or printing ink layer breaks and thus the connection. The paint or printing ink parts that are then exposed are no longer sticky and feel dry and, above all, can no longer connect two adjacent magazine pages. glue.

Laminating lacquers and so-called dry peel lacquers have similar effects.

According to an advantageous embodiment of the invention, the

To produce connection layer from a so-called cling coating layer. Cling-coating layers are adhesive layers which, once they have been separated from their adhesive partner, lose almost all of their stickiness. They can only be glued to themselves, which, however, is not a disadvantage when used as a connection layer in the manner indicated above.

According to an advantageous embodiment of the sample carrier according to the invention, the connection layer adheres to at least one of its two surfaces on at least one plastic film. If lacquers or printing inks are printed on plastic foils, the latter are usually subjected to a print pretreatment before the printing process in order to ensure that the lacquer or printing ink adheres firmly to the plastic foil. Such a print pretreatment can be a chemical "roughening" of the film in the molecular range using a "primer". Treatment under corona discharge also leads to the aforementioned molecular roughening. By refraining or partially refraining from pretreatment, the

Adhesive force between the connecting layer and the plastic film is specifically reduced, so that a defined adhesive force is established which, on the one hand, enables a secure hold and, on the other hand, enables the two layers mentioned to be separated without too much effort. Above all, a separating surface is precisely defined, along which the composite of sample holder and substrate (magazine side) is separated. Instead of (partially) refraining from

Print pre-treatment can alternatively or additionally be used with a satisfactory effect, partial separating layers, for example a silicone varnish applied point by point to the plastic film, in order to ensure a detachment behavior that is precisely defined in terms of location and force.

According to a particularly preferred embodiment of the present invention, the sample carrier has at least one auxiliary carrier which is fastened or can be fastened between the sample carrier and the connecting layer and / or between the connecting layer and the substrate.

Such an auxiliary carrier, which has, for example, a preferably transparent film and a pressure-sensitive adhesive layer attached to this film, can permanently represent link between the connection layer and the substrate (magazine side). Self-adhesive transparent films of this type are usually commercially available as rolls or as stacks. The auxiliary carrier can also serve to keep the sample carrier ready on an adhesive-repellent carrier strip (release liner), the auxiliary carrier ensuring with its pressure-sensitive adhesive layer the temporary connection to the adhesive-repellent carrier strip. If necessary, the sample carrier, including the connecting layer and auxiliary carrier, can be peeled off from the adhesive-repellent carrier (by hand or by machine) from the adhesive-repellent carrier layer, in order then to place the composite body comprising the sample carrier, connecting layer and auxiliary carrier on a substrate by means of the then exposed

Attach the pressure-sensitive adhesive layer of the auxiliary carrier (by hand or by machine). The connection between the pressure-sensitive adhesive layer of the auxiliary carrier and the substrate (magazine side) remains even after the sample carrier has been removed.

As an alternative or in addition to this, an identical or similar auxiliary carrier can also be arranged between the connecting layer and the sample carrier in order to ensure the secure connection between the connecting layer and the sample carrier. In terms of production technology, it is particularly favorable to have two auxiliary carriers connected via an adhesive-free connecting layer, which have a self-adhesive pressure-sensitive adhesive layer on their two opposite outer sides, on the underside of the

Attach sample holder and save the composite thus produced on an adhesive-repellent carrier.

According to a preferred embodiment of the invention, the sample carrier comprises a closed bag in which a cosmetic sample is arranged.

A cosmetic sample in this sense means perfume liquid, skin cleaning liquid, cream, lipstick material, make-up pigment, soap material or the like.

According to a preferred alternative embodiment of the invention, the sample carrier can have a piece of cardboard or paper that is impregnated with a fragrance and can also carry an imprint.

The invention is explained in more detail below with reference to the exemplary embodiments shown schematically in the drawings. The selected representations are not true-to-scale sectional representations. In particular, the layer thicknesses are for the sake of Clarity greatly increased compared to the other dimensions.

FIG. 3 shows a sample carrier for a cosmetic product according to a third embodiment in section;

Figure 4 shows a sample carrier for a cosmetic product according to a fourth embodiment in section;

FIG. 5 shows a basic illustration of a dispensing device with which a sample carrier according to FIG. 1 is attached to a magazine side.

The sample holder 1 shown in FIG. 1 has a bag 2, which in the example consists of two gas-tight foils 3 and 4, which are sealed together with adhesive 5 along their edge regions. Inside the bag 2 there is a cosmetic one

Sample in the form of a small amount of perfume liquid 6.

A first layer of pressure-sensitive adhesive 7 (pressure-sensitive adhesive) adheres to the outside of the film 4 of the bag 2 (lower side in the illustration in FIG. 1). A transparent first plastic film 8 adheres to the side of the layer of pressure-sensitive adhesive 7 opposite the film 4. The unit consisting of the transparent plastic film 8 and the first layer of pressure-sensitive adhesive 7 is referred to below as the first auxiliary carrier 14. The first plastic film 8 is connected to a second transparent plastic film 10 via a connecting layer 9. A second layer of pressure sensitive adhesive 12, the second transparent resin film 10 with a ^'substrate, in the example with a magazine page 13, respectively. The unit consisting of the second transparent plastic film 10 and the second layer of pressure-sensitive adhesive 12 is referred to below as the second auxiliary carrier 15.

The connecting layer 9 is adhesive-free and in the example consists of lacquer or printing ink. To produce the connecting layer 9, lacquer or printing ink, for example in a screen printing process, is placed on one of the two transparent plastic films 8 or 10 printed. Before the lacquer or printing ink hardens, the printed plastic film is laminated together with the second of the two plastic films. After curing, the two plastic films 8 and 10 are joined together. The printing pretreatment of the plastic films which is customary before printing on plastic films, for example by chemical treatment or ion irradiation, can be omitted on one or both of the transparent plastic films 8 and 10 or can only be carried out incompletely in order to obtain a reduced fastening force, which requires a manual separation of the connection of the two transparent plastic films 8 and 10.

In the present exemplary embodiment, the first transparent plastic film is preferred

8 before printing with lacquer or printing ink is subjected to a customary print pretreatment so that the connecting layer 9 adheres to the transparent plastic film 8 with maximum force. In contrast, the pre-treatment of the second transparent plastic film 10 does not take place. If the bag 2 is removed from the magazine side 13, the connection between the connecting layer 9 and the second transparent plastic film is made

10 separated. Only the second transparent plastic film 10 with its adhesive layer 12 remains on the magazine side 13. Because of the transparency of the two layers, this “residue” on the magazine side is almost not recognizable and in any case non-adhesive, so that there is no danger of two Glue the adjacent magazine pages together. The connection layer 9 remains on the underside of the sample carrier. Since it consists of a hardened lacquer or a hardened printing ink, it is non-sticky and completely dry, so that the person addressed by the advertising does not run the risk of getting dirty with adhesive.

Figure 2 shows a sample carrier for a cosmetic product according to a second embodiment in section. As can be seen from a comparison of FIGS. 1 and 2, instead of a bag 2 with perfume liquid 6 contained therein, a piece of cardboard 17 is provided, which can be printed on both its top and bottom. The prints 11 and 16 are only indicated in the figure by black horizontal bars. The piece of cardboard itself is soaked with a fragrance. Otherwise, the structure is identical to the structure explained in connection with FIG. 1.

Figure 3 shows a sample carrier for a cosmetic product according to a third embodiment in section. As can be seen from a comparison of FIGS. 2 and 3, the exemplary embodiment in FIG. 3 differs from the exemplary embodiment in FIG. 4 in that the auxiliary carrier 14 is omitted. The connection layer 9 is advantageously made from the transparent film 10 and the pressure-sensitive adhesive layer 12 best- Auxiliary carriers 15 printed with lacquer or printing ink and brought together with the piece of cardboard 17 which bears the fragrance sample before the lacquer or printing ink hardens.

Figure 4 shows a sample carrier for a cosmetic product according to a fourth embodiment in section. As can be seen from a comparison of FIGS. 3 and 4, the exemplary embodiment in FIG. 4 differs from the exemplary embodiment in FIG. 3 in that the auxiliary carrier 15 is also omitted. If, as in the above exemplary embodiments, the connecting layer consists of a lacquer or a printing ink, the two parts, namely the sample carrier in the form of the cardboard 17 and the substrate in the form of the magazine side 13, must be connected to one another immediately after one of the two parts with lacquer or Printing ink is printed before it cures or is cured (for example by UV radiation). If a so-called cling coating layer is used as the connecting layer, sample carriers 1 each provided with a connecting layer 9 can also be kept ready on a carrier and, if necessary, mechanically glued to substrates, such as magazine pages. Cling-Coating layers are self-adhesive layers that lose their adhesive properties after the first separation from the adhesive partner and feel dry and non-sticky.

Figure 5 shows a schematic diagram of a dispensing device with which a sample holder

1 is attached to a magazine page 13. The reference numeral 16 denotes an endless conveyor belt in its entirety, with which magazine pages 13, which are to be equipped with a sample carrier 1, are continuously conveyed. Sample carriers 1 of the type shown in FIG. 1 are arranged on an adhesive-repellent carrier tape 17, usually provided with a silicone layer, and adhere there easily by the action of the adhesive layer 12. The carrier tape 17 equipped with the sample carriers 1 is held in the form of a supply roll 18. The carrier tape 17 is pulled over a deflecting edge 19, the sample carriers 1 detaching from the carrier tape 17 and pressed by a roller 20 against a magazine side 13, the effect of the adhesive layer 12 creating a firm connection between the respective

Sample carrier 1 and the magazine page 13 is created.

The sample bodies shown in the exemplary embodiments in FIGS. 2 to 4 can also be processed as explained with reference to FIG. 5, the bottom layer shown in the sectional view in each case removing the function of the adhesive layer 12
