Description

DESCRIPTION

Double adhesive for a tobacco container or a paper dispenser

field of invention

The present invention relates to a double adhesive for a tobacco container, particularly a tobacco bag, or for a paper dispenser. The present invention further relates to a tobacco container with said double adhesive and a paper dispenser with said double adhesive.

Antecedent

Various packages for tobacco, smoking articles, such as cigarettes, cigars, or cigars, and tobacco-based products, such as snus or snuff, are well known in the art.

A container for hand-rolling tobacco can be a bag that is formed from an elastic sheet folded to form a pocket between two adjacent walls of the elastic sheet. One of the walls may extend continuously to form a flap for closing the pocket by overlapping the flap with an outer surface of one of the adjacent walls. While the adjacent walls may be partially hot stamped to close the pocket, the flap may comprise an adhesive label to reseal the bag. Alternatively, the hand-rolling tobacco may be packaged in a container, such as a closable cardboard-based container comprising a cylindrical shape or the like. Said container may comprise at least a base portion and a top portion, wherein the base portion and the top portion confine a first closable compartment for storing hand-rolling tobacco. In a horizontal section, the container may comprise a circular cross section, an oval cross section or a rectangular cross section. The base and the top portion may be connected through a screw connection, a press fit, an adhesive connection, a magnetic closure, or a hinge connection. Cigarette paper for hand-rolling cigarettes is usually provided in booklets containing a plurality of individual sheets of paper. For reasons of convenience, the booklets are stored in cigarette paper dispensers which are generally known in the art. A cigarette paper dispenser usually comprises a box containing a stack of cigarette papers and a folding lid attached to the box by a hinge. Each of the cigarette papers can be separately removed from the box through a slot through which a free end of the top of the cigarette paper extends.

Since cigarette papers are needed for hand-rolling cigarettes, it would be convenient to provide the paper booklets along with the tobacco pouch. However, tobacco pouches and cigarette papers are usually sold separately. Therefore, many users simply place the paper booklet inside the tobacco bag. However, due to the moisture in the tobacco, the adhesive strip on the paper can become activated and the tobacco can adhere to the adhesive.

GB2208352 discloses a cigarette paper booklet having adhesive means for fixing said booklet to a tobacco bag.

Therefore, it is known in the prior art to provide a tobacco pouch with an adhesive label on the outside. After peeling off a liner of the adhesive label, a paper booklet can be attached. However, another booklet cannot usually be attached to the tobacco bag once the paper booklet is finished, or vice versa. Therefore, the advantageous effect of the label quickly fades. Furthermore, by providing an adhesive booklet label on an outer surface of a bag, it further reduces the area that is available for merchandising or information to the user. Therefore, it is an object of the present invention to overcome or reduce at least some of the disadvantages of the prior art and to provide a dual adhesive for a tobacco container and/or for a paper booklet that allows a paper booklet to be attached to a tobacco container.

Summary of the invention

One or more of the drawbacks of the prior art could be avoided or at least reduced by the present invention, according to which there is provided a double adhesive for a tobacco container or paper dispenser according to the features of claim 1 , wherein the dual adhesive comprises a primary adhesive that is attached to a secondary adhesive. Thus, the primary adhesive comprises a base layer, preferably a flat base layer, with a first major surface and a second major surface opposite the first major surface. A first layer of adhesive is provided on the first major surface, preferably the entire first major surface, and a second layer of adhesive is provided on the second major surface. The secondary adhesive comprises a printable layer, preferably a flat printable layer, with a printable surface. A third adhesive layer is provided on an adhesive surface that is opposite the printable surface, preferably the entire adhesive surface, and a double-sided release layer is provided on the third adhesive layer. In other words, the secondary adhesive comprises a printable layer and an adhesive surface opposite the printable surface. In accordance with the present invention, the double release layer face is disposed between the second adhesive layer and the third adhesive layer. The double-sided release layer is configured to releasably adhere to both the second and third layers of adhesive. In other words, the double-sided release layer has release properties on its two main surfaces.

With the double adhesive of the present invention, a user can easily equip a paper dispenser for cigarette papers with the primary adhesive to secure the paper dispenser to a tobacco container. However, the double adhesive of the invention can also be used to attach something else to a tobacco container, such as a lighter or a pack of cigarette filters. To use the double adhesive, a user first affixes the first layer of adhesive to a paper dispenser, tobacco container, or the like. In this state, the double adhesive remains on the surface to which it is attached with the printable surface of the printable layer facing away from this surface. Therefore, any information on the printable surface, such as a brand name, slogan, or the like, is visible. To attach the paper dispenser to a tobacco container, the user removes the secondary adhesive from the primary adhesive and attaches the second layer of adhesive to the tobacco container, or vice versa. In general, the removed secondary adhesive is not tacky with the double-sided release layer remaining on it. However, once the user removes the double-sided release layer from the secondary adhesive, it can be attached to any surface via the third adhesive layer with the printable surface facing away from this surface. So again any information on the printable surface, such as a brand name, slogan, or the like, is visible, and thus the manufacturer of the double-sided adhesive can promote their brand or slogan, or the like. .

The third adhesive layer 33 also comprises a first major downward-facing surface and a second major upward-facing surface (each referring to the orientation of Figure 1, as indicated in the legend and reference signs ). A double-sided release layer, ie a release layer with release properties on its two main surfaces, is provided on the entire first major surface of the third adhesive layer 33 . Double-sided release layer 34 consists of a glassine paper liner with a double-sided silicone coating. In particular, the double-sided release layer 34 consists of white "Glassine Paper Liner B700-473/476" manufactured by VPF-Self-adhesive materials & coatings.

Unwanted tackiness of the dual adhesive 10 as a whole is prevented by a cover layer 40 which is disposed on a lower major surface (ie, the first major surface) of the first adhesive layer 21 . The cover layer is a 30 µm thick PET film coating. In particular, the cover layer consists of a transparent "30 jm-473/-476 PET film coating" manufactured by VPF-Self-adhesive materials & coatings. In general, the second major surface of the cover layer 40 is not sticky.

The use of a double adhesive 10 according to one embodiment of the invention is described below with respect to Figures 2 to 5.

In a first step, as illustrated in Figure 2, the double adhesive 10 is removed from the cover layer 40 used as a coil, on which the removed cover layer 40 can be disposed. In a next step, as illustrated in Figure 3 (A), the double adhesive 10 is placed with the first layer 21 of adhesive in a dispenser 60 of paper, in such a way that the first layer 21 of adhesive adheres to the dispenser. 60, as shown in Figure 3(B). In a next step, as illustrated in Figure 4(A), the secondary adhesive 30 is removed from the primary adhesive 20 by pulling the secondary adhesive 30 away from the primary adhesive 20. The double-sided release layer 34 is configured to adhere more strongly to the secondary adhesive 30 than to the primary adhesive 20, for example, by UV curing treatment on one side, such that the double-sided release layer 34 it detaches from the primary adhesive 20 and remains in the secondary adhesive 30.

In a next step, as illustrated in Figure 4(B), a paper dispenser according to one embodiment of the present invention with the second layer 23 of adhesive is placed on a container 50 of tobacco, in such a way that the second layer 23 of adhesive and thus the primary adhesive 20 adheres to the tobacco container 50 . Therefore, the paper dispenser 60 can be attached to the tobacco container 50, since the second adhesive layer 23 consists of a non-permanent adhesive. Thus, once, for example, the paper booklet within the paper dispenser 60 is empty, the paper dispenser 60 is removed from the tobacco container 50, whereby the primary adhesive 20 remains in the tobacco dispenser 60 . paper and can be disposed of along with it. Therefore, there is no layer of adhesive left on the tobacco container 50, where tobacco waste and dust stick to it.

Figure 5 illustrates the subsequent use of the secondary adhesive 30 that has been removed from the primary adhesive 20 as illustrated in Figure 4(A). After being removed from the primary adhesive 20, the secondary adhesive 30 has the printable surface 31 as a second major surface facing up and the double-sided release layer 34 as a first major surface facing down (each them referring to the orientation of Figure 5, as indicated in the legend and the reference signs). In general, due to the double-sided release layer 34, the secondary adhesive 30 is not tacky.

To use the secondary adhesive 30, the double-sided release layer 34 is first removed from the secondary adhesive 30 as illustrated in Figure 5(A). Thus, the third adhesive layer 33 is exposed as the first major downward facing surface of the secondary adhesive 30 remnants. Next, as illustrated in Figure 5(B), the remnants of the secondary adhesive 30 are placed with the third adhesive layer 33 on a complementary product 70, for example, a smartphone or a lighter, in such a way that the third layer 34 of adhesive adheres to complementary product 70, as shown in Figure 5(C). However, the tobacco bag 50 or the paper dispenser 60 can also be the complementary product 70 .

As shown in Figure 5(C), the printable surface 32 faces upwards, that is, away from the complementary product 70, once the third layer 33 of adhesive is adhered to this product 70. Thus, anything that is printed on the printable layer 34, such as a brand name, slogan, or other marketing material, is clearly visible to any user of the companion product 70 . Therefore, brand awareness of the manufacturer of the dual adhesive 10 is increased.
