Description

Description Wrapped adhesive sheet Technical field

The present invention relates to a pressure-sensitive adhesive sheet such as a wrapped adhesive plaster. Background art

As is generally known, a conventional adhesive bandage is provided with a pad for protecting the wound on an adhesive sheet having one surface as an adhesive surface, and furthermore, the adhesive surface of the adhesive sheet is attached to the adhesive surface. A release paper covering the pad is attached. In addition, the adhesive bandage to which the release paper is affixed is wrapped in wrapping paper, and is put on the market in packaging boxes and the like.

Emergency medical supplies such as adhesive plasters have the power to protect the affected area promptly in the event of a wound, etc.Because conventional adhesive plasters are long and slender, they are a bit bulky to carry around at all times. In general, few people usually wear it, and often carry it in their bags even if they carry it. Therefore, in the event of a bruise, etc., you will not be able to carry it or you will have to search inside a bag.

Even if a bandage is found, the operation is complicated because the bandage must first be removed from the wrapping paper, and the release paper must be peeled off and applied to the affected area. Furthermore, if you try to apply adhesive bandage in a hurry, the adhesive sheet may become wrinkled when the release paper is peeled off from the adhesive sheet, or the adhesive surfaces may stick together, making it difficult to adhere to the affected area. State also occurs. In this way, conventional bandages often failed to fulfill their role even though they were emergency medical products. Therefore, in the field of bandages, as disclosed in U.S. Pat. No. 4,264,008 and Japanese Patent Application Laid-Open No. 61-96958, FIGS. In addition, a film in which an adhesive surface is directly adhered to wrapping paper without providing a release paper on the adhesive surface of the film has been proposed.

However, when such a bandage is, for example, the one shown in FIG. 20 of Japanese Patent Application Laid-Open No. S61-19658, when the wrapping paper is spread from the opening and gradually peeled off from the adhesive sheet, Since the end of the adhesive sheet comes off the wrapping paper first, there is a problem that the adhesive surfaces of the released adhesive sheet stick to each other or the adhesive sheet becomes wrinkled, which makes it difficult to adhere to the affected part. In addition, when the adhesive bandage is applied to the affected area, the adhesive sheet must be held by hand, so that the adhesive force of the adhesive sheet may be weakened and the adhesive sheet may be easily peeled off.

On the other hand, in order to improve portability, for example, a bandage which is folded into a compact, such as the one disclosed in FIG. 14 of Japanese Patent Application Laid-Open No. 61-19658, has been proposed. Have been.

However, such a bandage also has a disadvantage that it is difficult to adhere to the affected area, similarly to the above-mentioned conventional bandage. In the bandage of FIG. 14 of Japanese Patent Application Laid-Open No. 61-196658, release paper is provided on the adhesive surface of the adhesive sheet on both sides of the pad. Even if the paper is folded into a box, it is desirable to reduce the amount of release paper as much as possible to save resources and reduce waste.

An object of the present invention is to improve a packaged pressure-sensitive adhesive sheet, and more specifically, to provide a packaged pressure-sensitive adhesive sheet with improved portability. In addition, the present invention provides a packaged pressure-sensitive adhesive sheet that can be stuck to an affected part by a single operation in an emergency as an emergency medical product. Furthermore, a packaged adhesive sheet that can be attached to the affected area without having the adhesive surface of the adhesive sheet is provided. Offer. Disclosure of the invention

In order to achieve the above object, a packaged pressure-sensitive adhesive sheet according to a first aspect of the present invention comprises: a substantially rectangular flexible pressure-sensitive adhesive sheet having a pressure-sensitive adhesive surface on one side; and a width of the pressure-sensitive adhesive sheet. Wrapping paper that is formed wider than the adhesive sheet and adheres around the adhesive sheet to cover the adhesive sheet, wherein the wrapping paper is folded from the folded portion such that the non-adhesive surfaces of the adhesive sheet face each other. In this state, the adhesive sheet comprises a front side wrapping paper that is releasably adhered to the adhesive surface of one adhesive sheet and a back side wrapping paper that is releasably adhered to the adhesive surface of the other folded adhesive sheet. The vicinity of the end of the front wrapping paper and the vicinity of the end of the back wrapping paper are adhered on the folded portion side of the sheet, and the ends of the front wrapping paper and the back wrapping paper are removed from the adhesion part at the bonding portion. An opening portion protruding in the direction is provided. On the other side, the end of the front wrapping paper and the end of the back wrapping paper are adhered, and the sticking force is applied to both ends of the pressure-sensitive adhesive sheet and the bonding parts of the front wrapping paper and the back wrapping paper. It is characterized by having a strong strong sticking part. Alternatively, a strong sticking portion having a strong sticking force is provided in a portion near both ends of the pressure-sensitive adhesive sheet and separated from the both ends to the bent portion side and the sticking portion between the front side wrapping paper and the back side wrapping paper. It is characterized by being provided. According to the packaged pressure-sensitive adhesive sheet of the first aspect, when the front-side wrapping paper and the back-side wrapping paper adhered from the opening portion are spread, the pressure-sensitive adhesive sheet is gradually peeled off from each wrapping paper, An adhesive portion between the front wrapping paper and the back wrapping paper on the opposite side to the unsealing part is pulled apart. At this time, since both sides of the pressure-sensitive adhesive sheet are provided with strong bonding portions having a strong bonding force with the front-side wrapping paper and the back-side wrapping paper, the pressure-sensitive adhesive sheet is inadvertently applied to the front-side wrapping paper and the backside. It does not come off the wrapper. Therefore, the adhesive sheet Since both ends are held by the front wrapping paper and the back wrapping paper, the user can attach the adhesive sheet to the affected area while holding the front wrapping paper and the back wrapping paper. . Then, the front wrapping paper and the back wrapping paper may be peeled from the adhesive sheet by further expanding the front wrapping paper and the back wrapping paper.

Thus, according to the packaged pressure-sensitive adhesive sheet of the first aspect of the present invention, since it is folded compactly, it is easy to carry, and the user can operate the affected part by a single operation of expanding the opening part. The above-mentioned pressure-sensitive adhesive sheet can be stuck on. Therefore, according to the present invention, it is possible to provide a packaged pressure-sensitive adhesive sheet which can sufficiently fulfill a role as an emergency medical product. Further, since the pressure-sensitive adhesive sheet can be stuck to the affected part without touching the pressure-sensitive adhesive sheet with a hand, the pressure-sensitive adhesive sheet is less likely to come off the affected part.

On the other hand, when the strong sticking portion is provided at both ends of the pressure-sensitive adhesive sheet, when the sticking force of the strong sticking portion is excessively increased, the front-side wrapping paper remains in a state where the pressure-sensitive adhesive sheet is stuck to the affected part. When the backing wrapping paper is peeled off, wrinkles may be generated at the end of the adhesive sheet, and the adhesive sheet may be easily peeled off. Further, when the difference between the adhesive force of the strong adhesive portion and the adhesive force of the other adhesive portions is reduced, the end of the adhesive sheet is peeled off from the wrapping paper before the adhesive sheet is attached to the affected area. May be affected. Furthermore, it is not always easy to control the adhesive strength of the strong adhesive part.

In view of this, the strong adhesive portion may be provided near both ends of the pressure-sensitive adhesive sheet and away from the both ends toward the bent portion. Thereby, as a result of increasing the sticking force of the strong sticking portion, the wrapping paper was peeled from the strong sticking portion. Even if the pressure-sensitive adhesive sheet is deformed when released, both ends of the pressure-sensitive adhesive sheet are not deformed, so that the pressure-sensitive adhesive sheet is firmly adhered to the affected part. Therefore, by separating the strong adhesive portion from both ends of the adhesive sheet, the adhesive force of the strong adhesive portion can be increased, so that the adhesive sheet is removed from the wrapping paper before the adhesive sheet is attached to the affected part. It is possible to prevent the end of the sheet from being peeled off, and to provide an adhesive sheet that is hardly peeled off from the affected part.

BEST MODE FOR CARRYING OUT THE INVENTION

Next, an embodiment of the packaged pressure-sensitive adhesive sheet of the present invention will be described with reference to FIGS.

First, a first embodiment of the present invention will be described. In this embodiment, as shown in FIG. 1 (a), the adhesive sheet 1 is folded in two from a central bent portion 2, and a pad 3 for scratch protection is provided on one surface. The wrapping paper 4 covers the periphery.

The adhesive sheet 1 is a flexible synthetic resin sheet similar to that used for general plasters, and has an adhesive surface 5 on one surface. The adhesive surface 5 of the adhesive sheet 1 is provided with a pad 3 formed by forcing a non-woven fabric into a rectangular shape. The pad 3 is folded from the bent portion 2 in FIG. 1 (a). Only one of the adhesive sheets 1 is provided. As described above, in this embodiment, the pad 3 is offset from the adhesive sheet 1 as shown in FIGS. 1 (c) and 1 (d).

The wrapping paper 4 has a base material made of paper, similarly to the wrapping paper used for conventional bandage, and has a coating made of synthetic resin such as polyethylene on the surface of the adhesive sheet 1 facing the adhesive surface. The front side wrapping paper 4a is releasably attached to the upper adhesive surface 5 of the folded adhesive sheet 1 in FIG. 1 (a), and the lower adhesive surface 5 is releasably attached. It consists of back side wrapping paper 4b to be stuck. The front side wrapping paper 4a and the back side wrapping paper 4b are adhered to each other around the adhesive sheet 1 as shown in FIG. 1 (b), and as shown in FIG. 1 (a). The left ends of the paper 4a and the back wrapping paper 4b protrude outward from the adhesive portion to form an opening tab 6.

Further, in the pressure-sensitive adhesive sheet 1 and the wrapping paper 4 of the present embodiment, the bonding force between the both ends of the pressure-sensitive adhesive sheet 1 and the wrapping paper 4 facing the pressure-sensitive adhesive sheet 1 is larger than that of the other bonding parts. A strong sticking section 7 is provided. In the present embodiment, as shown in FIG. 1 (d), the strong wrapping part 7 has an adhesive surface 5 other than both ends of the adhesive sheet 1 on the front wrapping paper 4 a and the back wrapping paper 4 b. Unevenness 8 is provided on the surface of the adhesive sheet 1 to reduce the area of contact with the adhesive surface 5 of the adhesive sheet 1 to reduce the adhesive force, and as a result, the adhesive force at both ends of the adhesive sheet 1 is increased. Like that.

The adhesive sheet 1 and the wrapping paper 4 formed in this way are When using the first wrapper 1, grip the opening tab 6 with a finger and peel off the front wrapping paper 4a and the back wrapping paper 4b so as to spread each other.
