The cover is disclosed. This comfort functional material includes antistatic materials, antibacterial materials, deodorant materials, aromatic materials and the like. As a result, it can be easily attached to and detached from items such as doorknobs, microphones, and telephones, and even items that can be touched by an unspecified number of people can be maintained hygienically and comfortably at all times.

Further, Japanese Patent Application Laid-Open No. 2007-13704 (Patent Document 2) discloses a doorknob marking illuminant which is made of a resin molded product containing a phosphorescent agent powder and is mounted around the doorknob on the door surface. There is. As a result, the position of the doorknob can be known even in a dark place due to the presence of the doorknob marking light emitter. Here, in the form of being attached to the doorknob itself, the gripping form of the doorknob becomes large and difficult to hold by attaching it, and there is a risk that it becomes dirty and the brightness decreases by touching it. Says that by installing it around the doorknob, those problems will be solved.

Further, in Utility Model Registration No. 3178824 (Patent Document 3), a cover that covers a doorknob, is formed in a tubular shape, and is provided with a non-slip portion inside, and the non-slip portion is provided. , A doorknob cover in which a large number of protrusions made of a rubber material are formed by a rubber print is disclosed. As a result, it is possible to provide a doorknob cover that is hard to fall off and the non-slip portion is hard to be damaged when it is put on the doorknob.

In recent years, infectious diseases have become more prevalent. For example, at the end of 2019, infection with the new coronavirus (COVID-19) was confirmed, and since then it has been in a state of pandemic worldwide. In particular, since the new coronavirus has strong infectivity, the parts that humans frequently come into contact with are regularly sterilized and washed, but such work is troublesome and time-consuming. There is.

Therefore, antibacterial / antiviral films that show inactivating ability against pathogens such as bacteria and viruses have appeared, and antibacterial / antiviral films are installed at sites that humans frequently come into contact with, such as doorknobs. Therefore, measures against infectious diseases are being taken.

However, for example, a grip ball type doorknob has a curved curved surface, so if the antibacterial / antiviral film is adhered as it is, there is a problem that the film is wrinkled or floats frequently. Here, if the doorknob is held through a film having wrinkles or floats, there is also a problem that the feeling of holding the doorknob becomes worse. Further, when the film after being adhered is peeled off, there is also a problem that it is difficult to peel off.

In the technique described in Patent Document 1, since the cover covers the doorknob or the like, when the user holds the doorknob from above the cover, the cover slides on the surface of the doorknob, and the user can rotate or operate the doorknob appropriately. It may not be possible to do so.

Further, although the technique described in Patent Document 2 can brighten the periphery of the doorknob in a dark room, it has no relation with the antibacterial / antiviral film and has a problem that the antibacterial / antiviral is insufficient.

The technique described in Patent Document 3 has a problem that the cover cannot be completely slipped, although the cover is made difficult to slip from the doorknob due to the presence of the non-slip portion.

In the technique described in Patent Document 4, when the doorknob cover is brought into close contact with a metal article such as a doorknob, the doorknob cover may be wrinkled or lifted.

Therefore, the present invention has been made to solve the above-mentioned problems, and provides an antibacterial / antiviral sheet that can be adhered without causing wrinkles or floating and can be peeled off cleanly. With the goal.

The antibacterial / antiviral sheet according to the present invention includes an antibacterial / antiviral film, an adhesive layer, a rubber sheet, and an adhesive layer. The antibacterial / antiviral film contains a metal powder having antibacterial and antiviral effects. The front surface of the adhesive layer is provided on the back surface of the antibacterial / antiviral film. The rubber sheet has a front surface provided on the back surface of the adhesive layer and has foamability. The adhesive layer is an acrylic adhesive layer having a front surface provided on the back surface of the rubber sheet and having removability showing an adhesive force weaker than the adhesive force of the adhesive layer.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings to help the present invention be understood. It should be noted that the following embodiment is an example embodying the present invention and does not limit the technical scope of the present invention.
<First Embodiment of the present invention>

As shown in FIG. 1, the antibacterial / antiviral sheet 1 according to the first embodiment of the present invention includes an antibacterial / antiviral film 10, an adhesive layer 11, a rubber sheet 12, and an adhesive layer 13. , Equipped with.

The antibacterial / antiviral film 10 contains a metal powder having antibacterial and antiviral effects. The front surface of the adhesive layer 11 is provided on the back surface of the antibacterial / antiviral film 10. The front surface of the rubber sheet 12 is provided on the back surface of the adhesive layer 11, and the rubber sheet 12 has foamability. The adhesive layer 13 is an acrylic adhesive layer having a front surface provided on the back surface of the rubber sheet 12 and having removability showing an adhesive force weaker than the adhesive force of the adhesive layer 11.

Here, in the present specification, "adhesion" means that an object and an object are closely attached to each other, and it is indicated that the object and the object are attached to each other and are not easily peeled off. On the other hand, adhesive means sticking to an object, and although it sticks to an object and is temporarily fixed, it means that it can be peeled off.

As a result, it can be adhered without causing wrinkles or floating, and can be peeled off cleanly.

That is, as shown in FIG. 2A, the antibacterial / antiviral sheet 1 according to the first embodiment of the present invention is attached to a part that humans frequently come into contact with, for example, a grip ball type doorknob 20, and the doorknob 20 Antibacterial and antiviral properties are given to. As a result, even if an unspecified number of people come into contact with the doorknob 20, it is possible to take measures against infectious diseases by antibacterial and antiviral properties.

Here, when the adhesive layer 13 of the antibacterial / antiviral sheet 1 is attached to, for example, a grip ball type door knob 20 which is a curved member, normally, the antibacterial / antiviral sheet 1 is attached to the door knob 20. When the antibacterial / antiviral sheet 1 is attached along the curved surface of the above, the curved surface of the antibacterial / antiviral sheet 1 and the curved surface of the door knob 20 do not match, and the antibacterial / antiviral sheet 1 is wrinkled or floated.

Therefore, in the present invention, by providing the foamable rubber sheet 12 between the antibacterial / antiviral film 10 and the adhesive layer 13, the curved surface of the antibacterial / antiviral sheet 1 and the curved surface of the door knob 20 are displaced from each other. Even so, the foamable rubber sheet 12 functions as a cushioning material, alleviates the deviation between the curved surface of the antibacterial / antiviral sheet 1 and the curved surface of the door knob, and wrinkles or floats on the antibacterial / antiviral film 10. To prevent the occurrence of. In particular, since the rubber sheet 12 has foaming bubbles, these bubbles function as a clearance to appropriately reduce the deviation between the curved surface of the antibacterial / antiviral sheet 1 and the curved surface of the doorknob. Can be done. This makes it possible to neatly attach the antibacterial / antiviral sheet 1 to a curved member such as a grip ball type doorknob 20.

Further, by providing the foamable rubber sheet 12, when the user grips the grip ball type doorknob 20 via the antibacterial / antiviral sheet 1, the metal doorknob 20 does not come into direct contact with the doorknob 20. It has a good feel and fit, and has the effect of enhancing the feel.

On the other hand, in the present invention, the adhesive layer 13 has a removability that shows a weaker adhesive force than the adhesive force of the adhesive layer 11, and an acrylic adhesive layer is adopted. Here, the acrylic adhesive layer (adhesive) has a better adhesive force to the adherend as compared with the silicone adhesive layer and the urethane adhesive layer, and has good followability and removability. Is also excellent. By adopting such an adhesive layer 13, if the antibacterial / antiviral sheet 1 is peeled off from the door knob 20, the material peeling between the antibacterial / antiviral film 10 held by the adhesive layer 11 and the rubber sheet 12 Rather, the interface peeling between the rubber sheet 12 held by the adhesive layer 13 and the curved surface (adhesive body) occurs preferentially. Therefore, the adhesive layer 13 of the antibacterial / antiviral sheet 1 can be neatly peeled off from the curved surface (adhesive body).

The antibacterial / antiviral sheet 1 according to the first embodiment of the present invention is not limited to the grip ball type doorknob 20, and as shown in FIG. 2B, any of the handle type, lever type, grip bar type, etc. It is also possible to apply to such a doorknob 20.

It is preferable to configure it in a shape). As a result, the arc shape of the antibacterial / antiviral sheet 1 fits on the slope of the substantially conical base of the grip ball type door knob, so that the antibacterial / antiviral sheet 1 is attached to the slope of the substantially conical base of the door knob without shifting. It can be attached and prevents the occurrence of wrinkles and floating of the antibacterial / antiviral sheet 1. Here, when the shape of the antibacterial / antiviral sheet 1 is an arc shape, for example, by cutting the corner portion into an arc shape, the corner portion is configured to be rounded and attached to the doorknob. The followability may be improved.

On the other hand, as shown in FIG. 2B, the handle-type doorknob has a substantially rectangular shape and has no curved surface. Therefore, as shown in FIG. 1, the shape of the antibacterial / antiviral sheet 1 is a plan view. It is preferable to configure it in an oblong shape or a rectangular shape. As a result, the oblong shape and rectangular shape of the antibacterial / antiviral sheet 1 fit the substantially rectangular flat surface of the handle-type door knob, so that the antibacterial / antiviral sheet 1 is neatly attached in the same manner as described above. It becomes possible. As described above, the shape of the antibacterial / antiviral sheet 1 can be appropriately redesigned according to the shape to be attached, and other examples include a circle, an ellipse, a triangle, a quadrangle, and a polygon. Can be done.
