Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved removable double-sided strong adhesive seal.

[0002]

2. Description of the Related Art There have been various pasting methods for pasting calendars, posters and the like on glass surfaces and walls. For example, on a smooth surface such as a glass surface, use transparent cellophane tape, gum tape, double-sided adhesive tape, etc. to fix the four corners of the calendar or poster, or in the case of a wood wall, press the calendar or poster etc. at several points with push pins. I have something to do. Also, memo papers, slips, calendars, circulation papers, etc. are attached to the surface of the refrigerator by a magnet to make them removable, but there are the following problems.

When attaching a calendar or poster to a smooth surface such as a glass surface, cellophane tape, gum tape, double-sided adhesive tape, etc. are used to stop the four corners.
Adhesive strength such as double-sided adhesive tape was so strong that it sometimes broke important calendars and posters. Also, when peeling off the calendar or poster, the adhesive remains on the glass surface,
It got dirty and didn't look good.

In the case of a wood wall, there are cases where the calendar, poster, etc. are pushed at several places to be stopped, but when the calendar, poster, etc. are removed from the wood wall, several push pin holes remain, and It didn't look good. In addition, in the case of a decorative wall etc., it is not possible to directly scratch it, and there are some things that it is difficult to open holes for push pins at several places, but it is pasted with cellophane tape, gum tape, double-sided adhesive tape, etc. As described above, when peeled off from the decorative wall or the like, the adhesive remains on the decorative wall and becomes dirty, which is not good in appearance.

Stick a memo paper, a slip, a calendar, a circulation paper, etc. on the side surface of the refrigerator with a magnet (magnet),
It is in a good condition to be removable at any time, but since the surface of the refrigerator is made of a metal decorative plate, it is easy to get scratches, and because the magnetic force is weak, the things you're stuck to may fall down, It wasn't a very good mounting method.

[0006]

The present invention has been made in view of the above problems, and it is a smooth surface such as the above-mentioned glass surface, a wood wall (including a decorative wall), or a refrigerator surface (a metal decorative plate). It is intended to provide a strong and removable double-sided adhesive sticker that can be easily attached to and removed from, etc. at a low cost.

A removable double-sided pressure-sensitive adhesive seal was characterized in that the removable adhesive layer (1) made of a special elastomer or the like was polymerized to form an integral sheet and cut into an arbitrary shape.

In a third aspect of the present invention, in a seal that can be repeatedly attached and used, urethane is formed on one side of a base material (3) whose structure is made of a polyester material with a strong adhesive layer (2) made of an acrylic material interposed therebetween. A re-peelable pressure-sensitive adhesive layer (1) made of a system-based special elastomer and another surface are polymerized with a re-peelable pressure-sensitive adhesive layer (1) made of a urethane-based special elastomer to form an integral sheet, The releasable strong double-sided adhesive seal is characterized by being cut into an arbitrary shape.

[0010]

When the present invention is used, the removable strong double-sided adhesive seals (A) are attached to the four corners of the calendar (5) or the poster (6) in advance, and the smooth surface (such as the glass surface (4) ( 4a) is sandwiched between the calenders (5) and posters (6) and the smooth surface (4a) such as the glass surface (4). The re-peelable pressure-sensitive adhesive layer (1) made of a urethane-based special elastomer or the like on both sides of A) is attached by the adhesive force.

In particular, this releasable strong double-sided adhesive seal (A) comprises a urethane-based special elastomer with a strong adhesive layer (2) made of an acrylic material on both sides of a base material (3) made of a polyester material. Since the re-peelable pressure-sensitive adhesive layer (1) made of, etc. is provided, the re-peelable pressure-sensitive adhesive layer (1) in which the strong pressure-sensitive adhesive is a urethane-based special elastomer or the like is removed from the strong pressure-sensitive adhesive layer (2) made of an acrylic material on both sides. Since a small amount is gradually ejected through it, if the adhesive strength becomes weak, wash it lightly with water and then return to the original adhesive strength simply by wiping off the water.If the adhesive strength becomes weaker, repeat the same way as above each time. You can use it.

Further, since the thickness of the removable strong double-sided adhesive seal (A) is 1 mm or more even though it has a multi-layer structure, the workability of attachment and detachment is efficient and convenient.

Since the surface of the removable strong double-sided adhesive seal (A) is the removable adhesive layer (1) made of urethane special elastomer or the like, it also serves as a cushioning material and is a push pin for a wood wall or a decorative wall. It can be used with peace of mind without damaging the holes.

When the calendar (5), poster (6), etc. are peeled off from the glass surface (4), the wood wall (7), the decorative wall (8), etc., the adhesive does not remain on the other side and is always clean. There is a feeling and it is beautiful.

Simply stick the memo paper (10), slip (11), calendar (5), circulation paper (12), etc. on the lateral surface of the refrigerator (9) with the removable strong double-sided adhesive seal (A). There is no fear of scratches, and since it has a strong adhesive force, it does not drop the attached ones.
