Detailed Description

The technical scheme of the invention is clearly and completely described in the following with the accompanying drawings. It should be understood that the embodiments described herein are only a few embodiments of the present invention, and not all embodiments. Unless otherwise specified, the technical means used in the examples are conventional means well known to those skilled in the art.

In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, are merely for convenience of description of the present invention, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.

As shown in fig. 1 and 2, the easy-to-tear self-adhesive label comprises a base paper 70, wherein the base paper 70 is release paper. An adhesive layer 50 is arranged on one side of the bottom paper 70, an air cavity 30 filled with air is arranged between the adhesive layer 50 and the surface paper 20, and a structure capable of leading the air in the air cavity 30 into the space between the adhesive layer 50 and the adhesive object is arranged between the adhesive layer 50 and the surface paper 20. Fig. 2 is a top view of the sticker, in which the air chamber 30 is a structure that cannot be seen from this view, and the air chamber 30 is illustrated by a dotted line for better illustration. The 4 dotted lines in the transverse direction in fig. 2 indicate the cutting reference positions of the adhesive sticker during production; of course, the producer can cut out other shapes and sizes according to the needs. The sizes of the structures shown in fig. 1 and 2 are only shown, and in actual use, the cross section of the air cavity 30 actually occupies an area not exceeding 1/2 of the cross section area of a single adhesive sticker; so that the adhesive layer 50 is in better contact with the facing layer 20 and the adhesive layer 50 is transferred to the facing layer 20 in its entirety during use.

The preferred scheme is as follows: the structure for introducing the gas in the gas chamber 30 between the glue line 50 and the adhesive object comprises a gas-guide tube 60 penetrating through the glue line 50. The air duct 60 is hollow, the air sealing film 40 is arranged inside the air cavity 30 and on the upper portion of the air duct 60, one side of the air duct 60 close to the air sealing film 40 is sharp, and the hardness of the air duct 60 is greater than that of the air sealing film 40. The material of the air duct 60 can be selected from rigid plastic, rigid rubber or other similar materials. The material of the air sealing film 40 can be selected from plastic films and the like, has certain toughness, can bear the air pressure in the air cavity, and even if most of air in the air cavity is extruded to the air sealing film 40, the air sealing film 40 can be kept not to be broken.

In normal state, namely normal processing and transportation, when the self-adhesive label is stuck on an adhesive object and the self-adhesive is normally processed and used, the air sealing film 40 and the air guide pipe 60 are not contacted with each other and are separated from each other, the air in the air cavity is kept in the self-adhesive label, and the self-adhesive label is in a slight bulging state. The user can also print various patterns on the surface of the face paper 20 by using the bulging shape according to the requirement, so that the label is in a three-dimensional state. When the adhesive sticker and the adhesive object need to be separated, the air duct 60 can be in contact with the air sealing film 40 under the action of external force, so that the air sealing film 40 is punctured. Namely: when the adhesive sticker is not needed any more, external force can be applied from the outer side of the face paper 20 to extrude the air sealing film 40, so that the air sealing film 40 is in contact with the air guide pipe 60, air is guided into the space between the adhesive sticker and the adhesive object from the interior of the adhesive sticker, and the adhesive sticker can be torn off conveniently. If the tearing condition of the adhesive sticker is not ideal, the outer surface of the face paper 20 can be further pressed, and the air in the adhesive sticker is extruded towards the air guide pipe 60 to help the air to enter between the adhesive sticker and the adhesive object. In order to facilitate the identification of the pressing position, an identification pattern may be printed on the face paper 20 at a position corresponding to the air-sealing film 40, or an identification mark may be fixedly attached, or a position corresponding to the face paper 20 may be provided as an uneven surface (not shown).

As shown in fig. 3, if the facial tissue 20 is made of a hard material, in order to facilitate the squeezing, a squeezing layer 80 may be further disposed on the facial tissue 20, the squeezing layer 80 is located at a position corresponding to the airway tube 60, and the hardness of the squeezing layer 80 is less than that of the facial tissue 20. The material of the extrusion layer 80 can be selected from EVA foam and the like.

The sealing membrane 40 needs to be contacted with the airway tube 60 after being subjected to a concentrated, accurately positioned force, and thus is ruptured. The pressure-sensitive adhesive is relatively evenly stressed under normal conditions, and generally cannot be exactly stressed by concentrated force with accurate position, so that the pressure-sensitive adhesive is punctured by the air duct 60. However, in order to further prevent the occurrence of the situation, the more preferable scheme is as follows: the face tissue 20 is fixedly connected with a thin protective film 10, the protective film 10 is arranged at the position corresponding to the air sealing film 40, the air sealing film 40 is completely covered, or the extrusion layer 80 is completely covered, the protective film 10 is made of a brittle material, and the hardness of the protective film is greater than that of the face tissue 20. For example, the material of the protective film 10 is hard plastic. When the label needs to be torn off, the protective film 10 is poked by a nail or other sharp objects, and the protective film 10 is a plastic sheet and can be broken or broken under the action of the sharp objects; and then further pressing the corresponding position of the protective film 10. The provision of the protective film 10 may also help to identify the pressing position. Meanwhile, the protective film 10 is different from the surface paper 20 in material, and protrudes from the surface of the surface paper 20; the user can also print a specific pattern on the surface of the protective film 10 according to the need by using the special effect, thereby further realizing the three-dimensional and beautiful effects of the label. The shape of the protective film 10 can be set to be an arc-like shape with one side higher than the other side lower than the other side as shown in fig. 1 and 3, and in this setting mode, when extrusion is needed, the protective film 10 can be directly crushed, and the protective film 10 can be directly buckled along a layer lower than the height of the protective film 10, and then the facial tissue 20 at the corresponding position is directly extruded. The shape of the protective film 10 is not limited to the shape of fig. 1 and 3, and may be a rectangular parallelepiped directly parallel to the face paper 20; or the shape of the middle concave part with higher two ends is set, the concave part corresponds to the part to be extruded, so that the position can be conveniently and quickly found, and the concave part is thinner and is more beneficial to being crushed; the protective film 10 may also be designed in other shapes depending on the overall design of the label.

The invention also provides a method for preparing the easy-to-tear self-adhesive, which comprises the following steps. The easy-to-tear adhesive sticker provided by the invention is not limited to be prepared only by the following steps, and a producer can completely adjust the adhesive sticker according to the existing production line and process the adhesive sticker on the basis of the preparation of the traditional adhesive sticker.
