Description

The present invention relates to an adhesive tape, and more particularly to an adhesive tape that covers skin wounds and the like and is used for hygiene and medical purposes.

Adhesive tapes that are widely used for hygiene and medical purposes are applied as medical supplies that are wound up into breathable adhesive tape rolls, adhesive plasters, or to stop wounds. Used to fix wounds, cover relatively small breakouts, and scars.

Such tapes apply an adhesive to one side of the base layer. Therefore, it is easy to fix and adhere to the skin. However, if the adhesive is directly adhered to the skin, ventilation of the affected skin is impeded, and swelling, itchiness, or hypersensitivity occurs easily. This seems to be a lot of experience.

In order to give favorable air permeability to the adhesive tape used for hygiene and medical use, a material having air permeability is usually selected as the material of the base layer. Such materials include, for example, non-woven fabric, cotton fabric, or a nylon sheet having a vent hole. However, even if these air-permeable materials are selected, since the adhesive is uniformly applied to one surface of the medical tape, it is covered with the adhesive layer to which the adhesive is applied. A big influence on the function. Therefore, the ventilation function of the conventional medical tape is not preferable.

  In addition, conventional adhesive tapes used for hygiene and medical use are not air permeable as described above. Therefore, if the tape is adhered to the skin, moisture will be emitted from the medical tape if it receives moisture due to sweat or other moisture. Inversely, it penetrates into the skin. In such a case, the adhesive strength is reduced and the film is easily peeled off. Excessively, since the skin is in contact with moisture for a long time, the skin becomes white and wrinkles occur, and bacteria are likely to propagate. For this reason, the wound is suppurated, and the wound is difficult to heal. These are caused by lack of breathability.

Examples of conventional tapes and sheets that cover the entire affected area include bandages, tapes, and gauze. Among them, in Japanese Patent Publication No. 3-75055, the affected area is covered with a film on the inside or inside of the woven fabric or non-woven fabric, and a well-known bandage or tape is adhered to the skin. A technique for obtaining the characteristics is disclosed. Such a design provides favorable adhesiveness as a surgical tape, however, its air permeability is not high and is not satisfactory to humans.

A plurality of continuous scratch grooves are formed on the adhesive layer formed on the base layer, and the scratch grooves have a diamond shape.

  Adhesive tape with air permeability according to this device has preferable air permeability, and when adhering to the skin, moisture does not stay in the affected area, maintaining a favorable hygienic state of the affected area, and promoting healing and healing of the affected area In addition to having an effect, the adhesive is less likely to cause hypersensitivity, and the adhesive tape is less likely to peel off.

The present invention provides a pressure-sensitive adhesive tape having high adhesive strength and favorable air permeability, and is formed by applying a base layer having air permeability and an adhesive to one surface of the base layer. A tape comprising an adhesive layer, wherein a plurality of continuous scratch grooves are formed on the adhesive layer formed on the base layer.
In order to describe the structure and characteristics of the medical tape having such a configuration, a specific example will be given and described in detail below with reference to the drawings.

FIG. 1 discloses a breathable tape according to the present invention. According to the drawings, it comprises a base layer 10 that is breathable. The material of the base layer 10 is selected from, for example, non-woven fabric, cotton cloth, or a nylon sheet having a vent hole.

In addition, an adhesive layer 20 coated with an adhesive is formed on one surface of the base layer 10, and a plurality of continuous scratch grooves 21 are formed on the adhesive layer 20. The scratch groove 21 is basically formed so as to exhibit a continuous wavy pattern, and is the most preferred embodiment. In such a form, even if the tape is cut from any direction, preferable adhesiveness is obtained over the entire width of the tape, and the adhered tape is not peeled off. Moreover, the breathable groove 21 has a favorable air permeability without the adhesive directly contacting the skin.

FIG. 5 discloses an embodiment in which two continuous scratching grooves 21 and 22 intersecting each other are formed. As a matter of course, the continuous wavy pattern may be replaced by a continuous broken line. For example, two continuous polygonal lines may intersect to draw a rhombus (not shown). Any of these pattern changes belongs to a change having an equivalent effect.

  The tape having air permeability according to the present invention is wound up as shown in FIG. 1 to form a tape roll, or as a sheet covering a wound as disclosed in FIG. 5, or as disclosed in FIG. It can be applied as an adhesive bandage or similar medical adhesive tape.

When implementing a tape having air permeability according to this device, as disclosed in FIGS. 2 and 3, first, an adhesive is applied to the base layer of the tape having an appropriate width. In this case, the guide roller 41 is provided in front of the base material 50 serving as the base layer, and the adhesive layer 20 is formed by uniformly applying an adhesive to one surface of the base material 50 using the adhesive application roller 40. .

  Next, the scratch groove 21 is formed on the base material 50 on which the adhesive layer 20 is formed. In this case, a scratch groove forming member 30 is provided on the rear side of the adhesive layer application roller 40. The scratch groove forming member 30 is arranged in a fence shape so as to contact at least one of the adhesive layers 20 to form a scratch groove. The scratch groove forming member 30 is reciprocated in a direction perpendicular to the traveling direction of the base material 50 to form a scratch groove 21 having a wavy continuous pattern on the adhesive layer 20 formed on the base material 50.

Another embodiment will be described with reference to FIGS. According to the drawing, as shown in FIG. 5, two or more scratch groove forming members 30 are provided at predetermined intervals, and are reciprocated in a direction perpendicular to the advancing direction of the base material 50. Scratch grooves 21 and 22 having a wavy continuous pattern in which two lines intersect are formed on the adhesive layer 20 formed on 50.

  By adjusting the angle or operation of the scratch groove forming member 30.31 with respect to the traveling direction of the base layer 50, a continuous polygonal line can be formed. For example, a pattern (not shown) in which a continuous polygonal line forms a rhombus (not shown). Etc. are included. All of these alternatives belong to modifications and changes that have an equivalent effect on the present invention.

The base material on which the adhesive layer 20 is formed and the scratch grooves 21 or 21 and 22 are formed is cut into various breathable tape applied products and packaged. The breathable tape application product includes a tape roll wound up as disclosed in FIG. 1, a sheet covering the wound as disclosed in FIG. 5, or a bandage as disclosed in FIG. 6, or a similar medical use.
