Description

  The present invention relates to a skin adhesive tape used as a tape for attaching an object to be adhered such as a mask or clothes to the skin surface of a human face, arm, or other part.

  Conventionally, various medical tapes for attaching gauze or the like to human skin have been proposed (see, for example, Patent Documents 1 to 3). Any of these adhesive tapes for skin has a pressure-sensitive adhesive layer made of an expensive pressure-sensitive adhesive composition that has no adverse effects such as irritation on the skin and has sufficient adhesiveness. These medical adhesive tapes for skin do not take into consideration the appearance or appearance, but are generally provided with an adhesive layer on one side.

  On the other hand, adhesive spray is provided as a means for preventing slipping off or loosening of socks or clothes in daily life. If this can be substituted with the above-mentioned adhesive tape for skin, cleaning of the skin after use becomes unnecessary, which is convenient. However, the conventional single-sided adhesive tape for medical use has a poor appearance because the tape appears in appearance. Although double-sided tape can be considered, the pressure-sensitive adhesive layer used in conventional adhesive tape for medical skin has a strong adhesive force to securely adhere to gauze etc. Skin irritation is too strong to use. On the other hand, if the adhesive strength is reduced, the adhesive strength to clothing will not be sufficient, and after use, only the tape will remain on the skin surface. End up.

JP 2005-58288 A JP 2002-360625 A JP-A-10-151185

  Therefore, in view of the situation described above, the present invention intends to solve the problem by interposing between the attachment object such as clothes and the skin and attaching both of them, and affecting the appearance and appearance. It can prevent slipping off and loosening of clothes etc., and there is almost no irritation to the skin, and only the tape does not remain on the skin surface after use, and the tape is held on the attached object side. The object of the present invention is to provide an inexpensive skin adhesive tape that can be repeatedly applied / removed to / from the skin.

In order to solve the above-mentioned problems, the present invention is an adhesive tape for skin for adhering an object to be adhered to the surface of human skin, the adhesive comprising an adhesive composition having adhesiveness to the object to be adhered Layer, a skin adhesion layer made of a soft silicone-based molded article having adhesiveness to adhere to human skin, and a fiber or resin base material such as paper or cloth interposed between the adhesive layer and the skin adhesion layer The adhesive tape for skin characterized by providing a sheet | seat was comprised. The silicone-based molded body is a molded body of a silicone polymer, and generally includes a silicone rubber having a modulus of elasticity higher than 10 ⁵ N / m ² and a low silicone gel.

  Here, it is preferable to apply a release sheet on the outer surface of the pressure-sensitive adhesive layer.

  Moreover, it is preferable that JIS-A hardness of the soft silicone type molded object of the said skin adhesion layer is 1-10.

  Furthermore, it is preferable that an intermediate layer made of a silicone-based molded body harder than the soft silicone-based molded body is laminated on the surface of the skin adhesion layer on the base sheet side.

  Moreover, it is preferable that the said base material sheet is a product made from a nonwoven fabric.

  The object to be adhered is preferably a fiber or resin such as paper or cloth such as a mask, clothes, underwear, diapers, sanitary products, care products, medical products, and the like.

  Further, a preferred embodiment is one in which the whole is configured as a long tape having a predetermined width or a single sheet-like tape that can be cut into an appropriate width.

  The adhesive tape for skin according to the present invention as described above can be attached between an object to be attached such as clothes and the skin, and can be attached to both the clothes and the like without affecting the appearance and appearance. It is possible to prevent slipping off and loosening. In addition, since the skin adhesion layer that adheres to the skin is made of a soft silicone-based molded article, there is almost no irritation to the skin, and it is easy to set the adhesion strength lower than that of the adhesive layer. Attaching / removing to / from the skin can be repeated many times while the tape is held on the adhesion target side without remaining on the skin surface. That is, unlike the conventional adhesive tape for skin, the other pressure-sensitive adhesive layer does not adhere to the skin, so that it has a design that can sufficiently increase its bonding strength considering only the adhesive force to the object to be adhered. Therefore, it is easier to increase the adhesive strength between the pressure-sensitive adhesive layer and the object to be adhered than the adhesive strength between the soft silicone-based molded product and the skin, and there is a disadvantage that only the tape remains on the skin. It can be easily avoided.

  In addition, since a fiber or resin base sheet is interposed between the pressure-sensitive adhesive layer and the skin adhesion layer, the composition of the pressure-sensitive adhesive layer penetrates the skin adhesion layer and gives irritation to the skin. Since there is no adverse effect, and since the soft silicone-based molded body of the skin adhesion layer can be in close contact with the base sheet, there is no inconvenience that part or the whole is peeled off and remains on the skin surface when peeling from the skin Has been. In addition, since the soft silicone-based molded body itself has sufficient elongation and can follow the elongation of the skin and the like, even if the skin is greatly deformed by moving the body while attached to the skin (for example, facial skin) Even if it is greatly deformed when laughing or screaming), it bends following the deformation and adheres to the skin and maintains good adhesion to the skin and an excellent wearing feeling.

  Moreover, since the JIS-A hardness of the soft silicone type molded body of the skin adhesion layer is 1 to 10, the adhesion to the skin can be made extremely good.

  Further, since an intermediate layer made of a silicone-based molded body that is harder than the soft silicone-based molded body of the skin-adhering layer is laminated on the surface of the skin-adhering layer on the base sheet side, such a hard silicone-based molded body Is excellent because it has excellent adhesion strength to the base sheet, and the bonding strength between the skin adhesion layer and the intermediate layer is the same between the silicone-based molded products. The penetration of the pressure-sensitive adhesive composition into the skin adhesion layer can be prevented more reliably. In addition, since such a hard silicone-based molded body also has elasticity, it can maintain a refreshing mounting feeling without reducing the mounting feeling.

  Moreover, since the base material sheet is made of a nonwoven fabric, it is possible to sufficiently maintain a high bonding strength with the soft silicone-based molded body and to have excellent stretchability.

(A), (b) is explanatory drawing which shows the state attached to the mask. Explanatory drawing which shows a use condition. (A), (b) is explanatory drawing which shows another use condition. Explanatory drawing which shows the modification of the provision form of the adhesive tape for skin. Sectional drawing which shows the adhesion tape for skin which concerns on 2nd Embodiment of this invention.

  Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a perspective view showing a state in which a skin adhesive tape according to the present invention is wound in a roll shape. FIGS. 1 to 6 show a first embodiment, FIG. 7 shows a second embodiment, and reference numeral 1 in FIG. Denotes a skin adhesive tape, 2 denotes an adhesive layer, 3 denotes a skin adhesive layer, and 4 denotes a base sheet.

  The adhesive tape 1 for skin of the present invention is a tape that is interposed between the two in order to attach the adherent object 6 to the surface of the human skin S as shown in the use mode of FIG. And as shown in FIG. 2, the adhesive layer 2 which consists of an adhesive composition which has adhesiveness to an adhesion target object, and the skin adhesion layer 3 which consists of a soft silicone type molding which has adhesiveness which adheres to human body skin, The base material sheet 4 is made of a fiber or resin such as paper or cloth interposed between the pressure-sensitive adhesive layer 2 and the skin adhesion layer 3. In such a tape, since the adhesive layer 2 on one side holds an adhesion target such as a mask, the skin adhesion layer 3 made of a soft silicone-based molded article on the other side adheres to the human skin. Attached objects can be attached to the human face, arms, and other free parts, and can be attached and detached multiple times, and can be used once and again like conventional expensive medical tapes. Unlike usability, it is convenient.

  In addition to the illustrated mask, the attachment object 6 can be a wide range of objects such as clothes, underwear, diapers, sanitary products, nursing care products, medical supplies, or other fibers or resin. In this example, when using the mask, as shown in FIG. 3 (a), the adhesive layer 2 is adhered to the mask fabric along the upper edge of the inner surface of the mask, and the skin adhesive tape 1 is attached. As shown in FIG. 4, the skin adhering layer 3 exposed on the surface of the tape 1 adheres along the nasal head, and the nose portion where a gap is likely to be formed between the mask and the mask is adhered. Can be buried, and it is possible to prevent dust and viruses from entering more reliably, and at the same time, mask displacement is also prevented.

  The attachment position of the skin adhesive tape 1 to the mask is not limited to the above example. For example, as shown in FIG. 3B, the skin adhesive tape 1 is attached not only to the upper edge of the inner surface of the mask but also to the left and right edges. In addition to attaching the tape 1 and ensuring close contact, attaching it only to the left and right edges, or attaching it along the top, bottom, left and right edges, the usage mode of the skin adhesive tape 1 depends on the user's preference. It can be used freely according to your requirements. As described above, the skin adhesive tape 1 according to the present invention is widely used to fill a gap between the object to be adhered 6 and the skin S or to prevent displacement. Thus, the adhesive tape 1 for skin can be used to prevent the sock (6) from slipping off, it can be suitably used for preventing slipping and loosening of clothes and underwear, and preventing slipping of diapers and sanitary products.

  Of course, it can also be used to simply attach the object 6 to the skin S. FIG. 5 is an example in which a gauze (6) for closing a wound such as an arm is attached using the skin adhesive tape 1 of the present invention, and the skin adhesive tape 1 is similarly applied to the mask described in FIGS. Can be attached to the mouth and nose without the ear straps, so that in the event of an emergency such as a disaster, a handkerchief, gauze, roll paper, cloth, etc. can be attached with the skin adhesive tape 1 without a mask. It can be attached to the mouth and nose to function as a simple mask.

  As the pressure-sensitive adhesive layer 2, a known pressure-sensitive adhesive composition having excellent adhesion to the adhesion target object 6 can be used. Depending on the material of the adhesion target object such as fiber or resin such as paper or cloth, the pressure-sensitive adhesive layer 2 is appropriately used. A pressure-sensitive adhesive composition used for a known pressure-sensitive adhesive tape having good adhesiveness can be selected. A release sheet 20 is attached to the outer surface of the pressure-sensitive adhesive layer 2, and in use, the release sheet 20 is peeled off, and the pressure-sensitive adhesive layer 2 is adhered and fixed to the adherend 6. In this example, the release sheet 20 is provided only on the pressure-sensitive adhesive layer 2, but it is also preferable to provide a similar release sheet on the outer surface of the skin adhesion layer 3.

  The skin adhesion layer 3 is composed of a soft silicone-based molded body having excellent adhesion to the skin. The soft silicone-based molded body has a JIS-A hardness of 1 to 10, preferably 2 to 6, and more preferably 3 to 4. As the silicone gel used for molding, various conventionally known materials such as a heat curing type, a room temperature curing type, a condensation curing type, and an addition curing type can be used. Moreover, about the adhesiveness (adhesion strength, adhesiveness) of the skin adhesion layer 3, it is 6-9 N / 25mm by the 180 degree peeling measurement method (average value) based on JISZ0237, More preferably, it is 7-8 N / It is set to 25 mm, more preferably 7.5 N / 25 mm. Thereby, the outstanding adhesiveness with respect to the skin S of a human body is obtained. For example, in the case of using an addition reaction curable liquid silicone gel as the silicone gel, it is softly formed by appropriately setting the mixing ratio of the curing agent, that is, the crosslinking agent. As such an addition reaction curable liquid silicone gel, it is preferable to use a highly safe material against the skin S such as “WACKER SilGel 612 A + B”, for example, Asahi Kasei Wacker Silicone Co., Ltd.

  The base material sheet 4 interposed between the pressure-sensitive adhesive layer 2 and the skin adhesion layer 3 is made of a fiber or resin such as paper or cloth, and the joint between the two is made strong, and peeling or the like is performed. In addition to preventing, the composition has a function of preventing the composition from the pressure-sensitive adhesive layer 2 from entering the skin adhering layer 3 that is in close contact with the skin and preventing adverse effects on the skin. Such a base sheet 4 is preferably made of fiber fabric, more preferably made of non-woven fabric, because it is required to have elasticity that can follow the expansion and contraction of the skin after attachment, but is not limited thereto, For example, a urethane sheet may be used. In addition, on the one side of a commercially available double-sided pressure-sensitive adhesive tape in which the pressure-sensitive adhesive layer 2 is present on both sides of the base sheet 4, the above-mentioned soft silicone-based molded article is further molded while the pressure-sensitive adhesive is removed or the pressure-sensitive adhesive is present. Of course, the skin adhesive layer 3 may be laminated to constitute the skin adhesive tape 1 of the present invention.

  As shown in FIG. 1, the skin adhesive tape 1 of the present example is a single long tape having a predetermined width as a whole, and is provided in a product form wound in a roll shape. Although it is configured to be cut and used, it is not limited to such a form, and a plurality of tapes having a predetermined width and a predetermined length as shown in FIG. 3 is attached and provided as a single sheet-like tape having an appropriate width in the vertical and horizontal directions as shown in FIG. 6B. In addition, a preferred embodiment is one in which the user can use it by cutting it into an appropriate shape according to the situation with scissors or the like.

  Next, a second embodiment of the present invention will be described based on FIG.

  In the present embodiment, as shown in the cross-sectional view of FIG. 7, a silicone-based molded body that is harder than the soft silicone-based molded body constituting the skin adhesion layer 3 on the surface of the skin adhesion layer 3 on the base sheet 4 side. The intermediate layer 5 is laminated. The intermediate layer 5 of such a hard silicone-based molded body is superior in adhesion strength to the base sheet 4 compared to the soft skin-adhered layer 3, and the skin-adhered layer 3 and the intermediate layer, which are the same silicone-based molded bodies, The bonding strength between 5 is also excellent and contributes to the increase in bonding strength as a whole. Moreover, the effect of more reliably preventing the intrusion of the pressure-sensitive adhesive composition from the pressure-sensitive adhesive layer 2 to the skin adhesion layer 3 that is in close contact with the skin is also achieved.

  The silicone-based molded body of the intermediate layer 5 is composed of the same silicone gel molded body having different curing conditions from the silicone-based molded body of the skin adhesion layer 3. The intermediate layer 5 is not required to have adhesiveness that adheres to the skin like the skin adhesion layer 3, but is required to be elastic enough to follow the deformation of the skin. The JIS-A hardness of the skin adhesion layer 3 measured with a spring tester A type is set to 1 to 10, preferably 2 to 6, more preferably 3 to 4 degrees, whereas the JIS-A of the intermediate layer 5 is set to JIS- The A hardness is preferably set to 14 to 16 degrees, more preferably 15 degrees. For example, when an addition reaction curable liquid silicone gel is used as a silicone gel, the skin adhering layer 3 is made soft and the intermediate layer 5 is made hard with different mixing ratios of curing agents, ie, crosslinking agents. Can do. As such an addition reaction curable liquid silicone gel, it is preferable to use a highly safe material for the skin such as “WACKER SilGel 612 A + B”, Asahi Kasei Silicone Co., Ltd. In addition, about the intermediate | middle layer 5, it is good also as a silicone rubber molded object instead of a silicone gel molded object.

  Specifically, the skin adhesion layer 3 is preferably laminated and formed on the intermediate layer 5 while the intermediate layer 5 formed on the base sheet 4 is in a semi-cured state. At this time, it is preferable that a soft silicone-based molded body is laminated and molded after applying a charge imparted to ultra-soft water on a semi-cured hard silicone-based molded body. It is possible to further improve the solubility and improve the bonding strength. Ultra soft water is obtained by removing calcium ions from the soft water, and the charge is applied by applying an alternating current or direct current to the ultra soft water. The intermediate layer 5 is not limited to a single layer, and may be a laminate of a plurality of layers made of a silicone-based composition or another composition.

  Moreover, according to this embodiment in which such an intermediate layer 5 exists, for example, the adhesive is removed or adhered to one side of a commercially available double-sided adhesive tape in which the adhesive layer 2 exists on both sides of the base sheet 4. In the presence of the agent, the intermediate layer 5 made of a hard silicone-based molded body is laminated and molded, and the skin adhesion layer 3 made of a soft silicone-based molded body is further laminated thereon to form the skin adhesive tape 1 of the present invention. When configured, even if the adhesive remains on one side of the double-sided adhesive tape, it may be mixed into the intermediate layer 5, but the intrusion of the adhesive is blocked there, and the intrusion into the skin adhesion layer 3 can be reliably prevented. It becomes.

  Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and can of course be implemented in various forms without departing from the gist of the present invention.
