Description

  The present invention relates to a shoe rub preventing seal, and particularly to a shoe rub preventing seal having a small contact area with the shoe inner surface.

  Shoe rub is often seen in the part from the back of the heel to the Achilles tendon, and also occurs on the outside of the fingertips and feet. In the resting state, the inner part of the shoe is only compressed so as to hit the skin, so that the shoe is damaged and the shoe is not rubbed. On the other hand, the close contact part moves with the movement of the ankle joint during movement such as walking. However, the skin does not respond to all the movements of the shoe, and after a slight movement, friction is generated by the movement of the skin away from the edge of the shoe and returning to the original position. Such repeated rubbing causes shoe rubbing. In the case of the back of the heel, when the shoe that does not fit the foot is worn, the skin around the Achilles tendon and the edge of the shoe are in close contact with each other, and this occurs due to movement such as walking. Shoe rubbing inside the shoe occurs almost in the same manner.

  Conventionally, sliding cushioning materials (see, for example, JP-A-2002-369836) and adhesive bandages with pads have been reported and put into practical use in order to prevent such shoe rubbing and to protect affected areas of shoe rubbing.

However, the conventional cushioning material and the adhesive bandage with a pad have a problem that the frictional force applied to the skin itself is not so much reduced because the entire surface is in contact with the inner surface of the shoe as a whole.
In addition, since the shoe rubbing site originally has a narrow gap between the shoe and the skin, if a cushioning material or a pad is inserted into the narrow portion, it is actually over-pressed and painful on the contrary. .

JP 2002-369836 A

  The present invention has been made in view of the above-described conventional problems and actual situations, and an object of the present invention is to provide a thin shoe rub prevention seal having a small adhesion area to the shoe inner surface.

  As a result of various studies to solve the above problems, the present inventor reduced the contact area if the strip-shaped parallel uneven surface was brought into contact with the shoe inner surface in a positional relationship orthogonal to the direction of movement of the foot. As a result, it was found that excellent lubricity was obtained and that the thickness could be reduced, and the present invention was completed.

  That is, the present invention provides a shoe rub preventing seal characterized in that a plurality of strip-shaped tape pieces are adhered and fixed in parallel at appropriate intervals on the pressure-sensitive adhesive layer surface formed on one surface of the sheet body. It solves the above problems.

By using the shoe rub preventive seal of the present invention, the contact area with the shoe inner surface is reduced, and excellent slipperiness is obtained between the shoe inner surface, so that the frictional force applied to the skin is reduced, resulting in more reliable shoe rub. Can be prevented.
In addition, it is sufficient that the strip-shaped tape piece has a rough surface so that the entire shoe inner surface is not in surface contact with the entire shoe surface, so that it can be made extremely thin. And so does not feel pain.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic plan view of a shoe rub preventing seal of the present invention from which a release film has been removed. BRIEF DESCRIPTION OF THE DRAWINGS FIG. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic cross-sectional explanatory view showing a state in which a shoe is worn by applying the shoe rub prevention seal of the present invention to a shoe rub occurrence site.

  Embodiments of the present invention will be described below with reference to the drawings.

  1 and 2, reference numeral 10 denotes a sheet body, and an adhesive layer (not shown) is formed on one surface thereof. Reference numeral 20 denotes a strip-shaped tape piece, which is fixedly adhered to the surface of the pressure-sensitive adhesive layer of the sheet body 10 in parallel at an appropriate interval. Reference numeral 30 denotes a release film that covers the surface of the sheet body 10 on which the strip-shaped tape piece 20 is stuck and fixed.

  The sheet body 10 has flexibility to form an uneven surface along the strip-shaped tape piece 20 when a shoe rubbing occurrence site is applied. As such a sheet body 10, for example, a synthetic resin film having a slipperiness of 0.01 to 0.2 mm is suitably used. Note that the shape of the sheet body 10 may be any shape such as a square, a circle, and a polygon.

As the strip-shaped tape piece 20, a synthetic resin film having a length of 10 to 80 mm, a width of 2 to 6 mm, and a thickness of 0.05 to 0.5 mm is preferably used, and the number is preferably about 3 to 8. .
Moreover, as a space | interval between the strip-shaped tape pieces 20, about 2-6 mm is preferable.

Next, a method for using the shoe rub preventing seal according to the above embodiment will be described.
First, the release film 30 is peeled and removed to obtain the state shown in FIG. Next, the surface of the strip-shaped tape piece 20 side of the sheet body 10 is applied to a shoe rubbed portion of the human body and lightly pressed by hand from the outside, and the sheet body 10 is present between the strip-shaped tape pieces 20 by the adhesive layer. If it sticks to the part 40, as shown in FIG. 3, an uneven surface will be formed along the said strip-shaped tape piece 20. As shown in FIG. If the shoe is worn in such a state, the state shown in FIG. 4 is obtained, the contact area with the inner surface of the shoe 50 is reduced, and excellent slipperiness is obtained.
