Description

  The present invention relates to a double fold-forming pressure-sensitive adhesive tape for sticking to a human fold to form a double fold and a method for producing the same.

Conventionally, this type of double wrinkle-forming pressure-sensitive adhesive tape (Japanese Patent No. 3277180) is obtained by applying a pressure-sensitive adhesive to a thin tape-shaped member that is stretchable and formed of a synthetic resin that is elastic and stretchable after the stretching. There is something configured by.
In the present invention, when a double fold is formed by a consumer during use, the strength of the adhesive tape in the process of stretching the adhesive tape in the left-right direction may be cut halfway due to weakness. For this reason, the double wrinkle-forming pressure-sensitive adhesive tape has to be carefully stretched again using another double wrinkle-forming pressure-sensitive adhesive tape, so that there is a problem that not all products are effectively used. The reason is considered to be that when the adhesive tape is stretched into a single thread, the adhesive tape itself is stretched too thin and the strength is insufficient.

An adhesive tape for forming double folds according to an embodiment of the present invention will be described with reference to the drawings.
Reference numeral 1 denotes a synthetic resin film that can be stretched in the form of a thread formed at one or a plurality of intervals, and an adhesive (not shown) is applied to the entire front and back surfaces in advance to form a horizontally long rectangular shape. . The material of the synthetic resin film 1 that can be stretched into a yarn and used as an adhesive tape for forming double wrinkles is, for example, a transparent thermoplastic resin film such as polyethylene, polyester, etc. A film coated with (not shown) is used.
In this example, the synthetic resin film 1 that can be stretched into a thread shape, such as a set of 10 sheets, a set of 15 sheets, or a set of 20 sheets, is cut into a size that can be obtained.

  Reference numeral 2 denotes a mount made of thermoplastic resin or paper. The back surface of the synthetic resin film 1 that can be stretched in a thread shape is detachably attached to the surface of the mount 2. In this example, the mount 2 is shown attached to the transparent thermoplastic resin mount 2. However, the mount 2 may be made of moisture-resistant paper.

  The synthetic resin film 1 that can be stretched in a thread shape and stuck on the mount 2 is stuck so as to be peelable in a state of being cut into a set of, for example, 10 sheets. On the back surfaces of both end portions of the synthetic resin film 1 that can be stretched into a thread shape, a grip portion 3 that is non-adherent and colored in a chromatic color such as purple is affixed.

Reference numeral 4 denotes a rectangular synthetic resin film 1 that can be stretched into a thread shape that is formed at one or a plurality of intervals , excluding the grip portions 3 that are attached to the left and right ends (hereinafter referred to as “ synthetic resin that can be stretched into a thread shape ”). It is a release paper that is releasably attached to the surface of the “made film” .
At each central portion of the release paper 4, a rectangular cut-out portion 6 that penetrates the release paper 4 and the synthetic resin film 1 that can be stretched in a thread shape is provided between the tips of the left and right gripping portions 3. A plurality of threaded portions to be formed and stretched are kept at a constant interval, and a punched-out portion 5 that cuts the synthetic resin film 1 that can be stretched into individual thread shapes into one unit is simultaneously removed. Formed with a mold. It is important that the punched-out portion 5 by the punching die is not formed on the mount 2. This is to avoid deterioration of the adhesive (not shown) adhering to the synthetic resin film 1 that can be stretched into a thread shape when it is pulled out. In this example, the case where the punched portion is formed using the punching die has been described. However, the present invention is not limited to this, and laser beam or the like may be used. However, the punched portion is not formed on the mount 2. It is common to do so.

  In this example, when using the left and right grips 3 and slowly pulling left and right, the gap formed in the center gradually narrows and at the same time two parallel thread-like parts are formed. By twisting several times to an appropriate number of times, the strength is further increased by the twisting of a plurality of thread-like portions and the synergistic effect of the pressure-sensitive adhesive. .

In this example, the case where two parallel thread-like parts are formed is shown, but the present invention is not limited to this, and as shown in FIG. By increasing the number of punched-out portions, a stronger double heel composed of three or more twists is formed.

  The present invention is a good news for people who suffer from double wrinkles, as the strength of the filamentous resin increases greatly by simply twisting several synthetic resins stretched into a string at intervals with a finger gripped on the left and right several times. Will be activated and further demand will be generated.
