Description

  The present invention relates to an adhesive tape roll for cleaning wound so that an adhesive surface faces the front side, and more specifically, relates to an adhesive tape roll that can be used without selecting a floor surface.

  An adhesive tape roll for cleaning is used to wrap an adhesive tape with an adhesive surface on one side in multiple turns so that the adhesive surface faces the front side, and attach it to a dedicated jig to cover the floor or other surface. By rolling while making contact with the cleaning surface, dust on the surface to be cleaned is captured.

  Many of the conventional pressure-sensitive adhesive tape rolls are so-called solid-coated pressure-sensitive adhesive tape rolls in which a pressure-sensitive adhesive is applied with a uniform thickness over almost the entire surface of a substrate. Since the solid-coated adhesive tape roll has a large contact area with the floor surface, there is an advantage that dust can be captured over the entire surface.

  On the other hand, since the pressure-sensitive adhesive layer is uniformly formed on the entire surface, when the tape is wound in a roll shape, the tape is hard and cannot follow the fine unevenness on the floor surface flexibly and is small. When stones or the like adhere, there is a problem that the adhesive surface of the surrounding portion floats and the dust capturing power is reduced.

  Therefore, a streaked-type adhesive tape roll that has solved the drawbacks of the solid-coated type adhesive tape roll has been newly developed. That is, for example, as shown in Patent Document 1, a streaked-type pressure-sensitive adhesive tape roll is formed by alternately arranging pressure-sensitive adhesive layers and non-pressure-sensitive adhesive layers along the winding direction of a substrate.

  According to this, since the pressure-sensitive adhesive layer is formed in a streak shape, the portion without the pressure-sensitive adhesive layer becomes a gap and creates cushioning properties. You can catch the garbage on the surface regardless of the size.

However, the adhesive tape roll stripe coating type, amount without applying an adhesive to the entire surface, of course trapping force of dust is reduced. Therefore, a further improved product of the adhesive tape roll as in Patent Document 2 is provided.

  The pressure-sensitive adhesive tape roll described in Patent Document 2 describes that a pressure-sensitive adhesive layer is formed on the entire surface of a base material, and a weak pressure-sensitive adhesive having a weak adhesion is formed on the pressure-sensitive adhesive layer in a stripe shape. . According to this, by using two strong and weak pressure-sensitive adhesives, a universal pressure-sensitive adhesive tape roll that can be used for carpets and flooring can be obtained.

  However, the following problems remain in this adhesive tape roll. In other words, although the problem of sticking to the floor and lack of cushioning properties, which are the disadvantages of solid coating, have been resolved, the weakness of the streaked coating has resulted in the disadvantage of reducing the ability to capture dust at the streaked coating. .

  In addition to this, two types of pressure-sensitive adhesives must be prepared, which increases the material cost. Moreover, since the streaked coating layer is formed on the solid coating layer, two steps are required, and the manufacturing time and cost increase accordingly.

Further, when the pressure-sensitive adhesive tape is wound, since the streaked coating layer is a weak pressure-sensitive adhesive, the retainability between the pressure-sensitive adhesive surface and the release treatment layer on the back surface of the base material is poor, and the tape is easily rewound. Furthermore, the stripe coating layer (weak adhesive layer) may be peeled off from the base layer (strong adhesive material layer) and transferred to the floor surface.

  Then, this invention was made | formed in order to solve the subject mentioned above, Comprising: The objective is to provide the adhesive tape roll which can be used with respect to various floor surfaces.

In order to achieve the above-described object, the present invention has several features described below. In the invention according to claim 1, the adhesive tape having an adhesive surface formed on one surface of the substrate is wound so that the adhesive surface faces the front side, and rolls on a surface to be cleaned such as a floor surface. by, in the adhesive tape roll to capture objects to be cleaned of dirt and dust on the surface to be cleaned, the said adhesive surface, the cross-sectional area as the direction from the surface of the upper Kimotozai the tip of the vertical rectangular direction is gradually Adhesives formed so as to be in the shape of smaller cones are scattered at a predetermined interval, and the adhesive is contacted between the pressure-sensitive adhesive surface and the surface to be cleaned so that the front end side of the adhesive is The contact area between the pressure-sensitive adhesive surface and the surface to be cleaned is changed to adjust the pressure-sensitive adhesive force of the pressure-sensitive adhesive surface to the surface to be cleaned .

According to a second aspect of the invention, in the above claim 1, said adhesive, each of which is characterized by Tei Rukoto formed in a conical shape or pyramidal shape.

  A third aspect of the invention is characterized in that, in the first or second aspect, the tip of the adhesive is a convex spherical surface or a concave spherical surface.

  A fourth aspect of the invention is characterized in that, in the first, second, or third aspect, the pressure-sensitive adhesive is provided with a step as it goes from the surface of the base material to the tip.

  According to the present invention, when the pressure-sensitive adhesive surface is lightly pressed against the surface to be cleaned, the pressure-sensitive adhesive is formed into a cone shape in which the cross-sectional area gradually decreases from the surface of the substrate toward the tip. Since the contact area is small, it becomes a weak adhesive type. On the other hand, when it is pressed strongly, the adhesive is deformed and the contact area becomes large, resulting in a strong adhesive type. Can be used for almighty, such as flooring and carpets.

Next, embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited thereto. 1 is a perspective view of an adhesive tape roll according to the first embodiment of the present invention, FIG. 2 is a front view of the adhesive tape of the first embodiment, and FIG. 3 is a cross-sectional view taken along line AA in FIG. Fig. 4a (a) is an enlarged schematic view of the adhesive, and (b) and (b) are modified examples thereof. 4b (a) to (f) are perspective views showing modifications of the pressure-sensitive adhesive. 5A to 5C are explanatory views for schematically explaining the cleaning mechanism of the pressure-sensitive adhesive tape roll of the present invention. FIG. 6 is a perspective view showing another embodiment of the pressure-sensitive adhesive tape roll of the present invention. Fig.7 (a) is a schematic diagram of the manufacturing apparatus of the adhesive tape roll of this invention, (b) is a schematic diagram showing the modification of a manufacturing apparatus.

  As shown in FIGS. 1 to 3, the adhesive tape roll 1 includes an adhesive tape 2 having a dust removal surface 22 (adhesion surface) formed on one surface of a tape base 21, and the dust removal surface 22. Is wound in a roll shape along the core 3 so as to face the front side (upper surface side in FIG. 1).

  In this example, a paper core such as cardboard is used as the core 3, but a synthetic resin core may also be used. Furthermore, a so-called coreless structure in which the winding core 3 is wound without using the winding core 3 may be used. In the present invention, the configuration of the winding core 3 is arbitrary.

  Dry edge portions 24 and 24 as non-adhesive portions are provided at both ends in the width direction across the dust removal surface 22 of the adhesive tape 2, but in the present invention, the dry edge portions 24 and 24 are optional. It is a component.

The tape base material 21 is made of, for example, paper, and a laminate film 23 for reinforcing and peeling the tape base material 21 is provided on the back surface (lower surface in FIG. 3 ). In this example, the laminate film 23 is made of polyethylene and is integrally bonded to the back surface of the tape base material 21. The material of the tape base material 21 may be arbitrarily selected according to specifications.

  In the present invention, the laminate film 23 is an optional component, and can be made unnecessary by using a resin film or the like instead of the tape substrate 21 of paper. Also, the laminate film 23 can be omitted by controlling the composition of the pressure-sensitive adhesive.

  The dust removal surface 22 is constructed by the pressure-sensitive adhesive layer 4 formed along the base material 21. The pressure-sensitive adhesive layer 4 is a single pressure-sensitive adhesive formed by uniformly applying a pressure-sensitive adhesive such as SIS (styrene-isoprene-styrene) system along the surface of the tape substrate 21.

  Referring also to FIG. 4a, the pressure-sensitive adhesive layer 4 has a large number of pressure-sensitive adhesive portions 41 that are formed in a conical shape in which the cross-sectional area gradually decreases as the pressure-sensitive adhesive moves from the surface of the substrate toward the tip in the vertical direction. These adhesive portions 41 are regularly arranged on the substrate 21 with a predetermined interval.

  In this example, each of the adhesive portions 41 is formed in a conical shape. However, as shown in FIG. 4A (b), it may be a triangular pyramid, or as shown in FIG. 4A (c). It may be a pyramid and may be formed in a cone shape in which the cross-sectional area gradually decreases from the base end side to the tip end side of the base material 21. Specific dimensions such as a radius and a height of these adhesive portions 41 may be arbitrarily changed according to specifications.

  As other shapes, as shown in (a) of FIG. 4b, the tip of each pressure-sensitive adhesive layer 41 having a cone, triangular pyramid, or quadrangular pyramid shape may be formed in a hemispherical convex shape. Further, as shown in FIG. 4b (b), the tip end side may be cut out flat. As shown in FIGS. 4b (c) to (e), a step may be provided between the base end side and the tip end side, and as shown in FIG. 4b (f), the tip is made hemispherically concave. Good.

  According to this, as shown in FIG. 5A, when the pressure-sensitive adhesive tape roll 1 is lightly pressed against the surface to be cleaned F and rolled, the tip of the pressure-sensitive adhesive portion 41 is slightly crushed, but the gap G remains large. Therefore, the contact area with respect to the surface F to be cleaned is small, and as a result, the adhesive force is weakened, and the same cleaning effect as that of so-called streak coating is obtained. Therefore, this is effective for a smooth floor surface such as a flooring floor on which the pressure-sensitive adhesive layer 4 is easily adhered.

  For a relatively rough floor surface F such as a cushion floor or a tatami mat, as shown in FIG. 5B, the adhesive tape roll 1 is rolled while being pressed slightly. According to this, the tip of the adhesive part 41 is crushed by pressing, so that the gap G is reduced and the contact area with the floor surface F is increased, so that the adhesive force is increased and dust on the relatively rough cleaning surface is more reliably secured. Can be captured.

  For a very rough floor surface F such as a carpet or a carpet, as shown in FIG. 5C, the adhesive tape 41 is crushed and flattened by strongly pressing the adhesive tape roll 1, so that the gap G The contact area with respect to the floor surface F is maximized, the adhesive force is further increased, and the cleaning effect is the same as that of so-called solid coating, so that dust adhering to the rough floor surface F can be reliably captured.

  In this example, the adhesive portions 41 are arranged in a grid pattern along the feeding direction and the width direction of the base material 21. However, the arrangement method of the adhesive portions 41 may be arranged in a staggered manner or diagonally. They may be arranged in a line, etc., and may be arbitrarily selected according to specifications.

  Alternatively, as shown in FIG. 6, the adhesive portion 41 may be formed in a rib shape extending in a predetermined width along the surface of the substrate 21. In this example, it is formed in a rib shape having a triangular cross section, and is regularly arranged along the feeding direction of the base material 21. According to this, the adhesive force can be adjusted depending on the pressing degree of the adhesive tape roll 1.

  Normally, the adhesive tape 2 is provided with cuts 5 for cutting at predetermined intervals. In this example, the cut 5 is a perforation formed in a direction perpendicular to the winding direction of the pressure-sensitive adhesive tape 2 at an interval that is less than 360 ° in circumferential length. The configuration may be arbitrary.

  Next, an example of the manufacturing method of the adhesive tape roll of this invention is demonstrated. As shown in FIG. 7A, the adhesive tape roll manufacturing apparatus 100 is installed such that a pressure-sensitive adhesive 111 is stored in a reservoir 110 and a part is immersed in the pressure-sensitive adhesive 111 in the reservoir 110. The transfer roll 120 and the press roll 130 arrange | positioned so as to oppose the transfer roll 120 on both sides of the tape base material 21 are included.

  In this example, the pressure-sensitive adhesive 111 is stored in the reservoir 110, and the pressure-sensitive adhesive 111 is supplied to the transfer roll 120 by immersing the transfer roll 120 therein, as shown in FIG. 7B. Alternatively, the guide roll 140 may be brought into contact with the transfer roll 120, and the adhesive 111 may be stored in a space formed between the transfer roll 120 and the guide roll 140.

In this example, the transfer roll 120 is a so-called gravure roll in which a concave surface is provided by etching on the roll surface. The transfer roll 120 is provided with a squeegee 150 for leveling the adhesive 111 adhering to the transfer roll 120 and removing excess.

In applying the pressure-sensitive adhesive layer 4, the pressure-sensitive adhesive 111 is filled in the concave surface by rotating the transfer roll 120 immersed in the reservoir 120. When the transfer roll 120 is further rotated, the adhesive 111 is spread over the surface of the transfer roll 120 by the squeegee 150 that is in contact with the end surface of the transfer roll 120, and the excess adhesive 111 that protrudes is removed.

It is supplied so that one surface of the tape base material 21 is in contact with the transfer roll 120 that has passed through the squeegee 150, and the other surface is pressed by the guide roll 130. Thus, the adhesive 111 applied to the transfer roller 120 is transferred to the tape substrate 21, the adhesive portion 4 1 of the pressure-sensitive adhesive layer 4 is made form.

According to this, there are few coating processes and the usage-amount of an adhesive can also be reduced, As a result, production cost can be reduced significantly.
