Description

  The present invention relates to an adhesive tape.

Conventionally, what was described in patent document 1 is known as an adhesive tape which can fix articles | goods etc. to front and back. In this conventional example, the adhesive tape is formed by applying and forming a strong adhesive resin layer and a weak adhesive resin layer in which a re-peeling resin is coated on the front and back surfaces of a substrate.
Japanese Patent Laying-Open No. 2005-48111

  In general, when you want to easily fix a lightweight article such as a poster to the wall of a room, double-sided adhesive tape as in the previous example is often used. If the peelability of the adhesive layer is increased to prevent tearing, the fixing force will be reduced, while if the adhesiveness is increased, traces may remain when peeling from the wall. You will have to be careful and work carefully.

  Moreover, when it fixes to a wall surface for a comparatively long period of time with an adhesive, there exists a problem that a stain and discoloration will arise on a wall surface by the effect | action of the adhesive component.

  The present invention has been made to eliminate the above drawbacks, and can increase the fixing force to the wall surface, has excellent removability, and does not impair the appearance of the wall surface when peeled off. The purpose is to provide.

According to the present invention, the object is
An adhesive part 4 formed by laminating an adhesive 3 on the surface of a substrate 2 through which the staple 1 can penetrate;
A staple driving portion 5 that is partitioned from the adhesive portion 4 and is formed in the remaining region of the surface of the base material 2 and has a width that allows the staple 1 to be driven;
This is achieved by providing an adhesive tape that can fix the back surface side of the base material 2 by driving the staples 1 into the staple driving portion 5 and can be attached to the front surface side of the base material 2 by the adhesive 3.

  In the present invention, the staple 1 means that specified as No. 10 of staples for staples in JIS (Japanese Industrial Standards), and specifically, a wire having a cross section of approximately 0.3 mm × 0.5 mm square. It refers to the one formed by bending in a U shape.

  According to the present invention, the pressure-sensitive adhesive tape has the pressure-sensitive adhesive portion 4 formed by partitioning the surface of the base material 2 and the staple driving portion 5, and the base material is driven by driving the staple 1 into the staple driving portion 5. 2 The back side can be fixed, and the adhesive 3 of the adhesive part 4 is formed so that it can be attached to the surface of the substrate 2. Therefore, it is possible to easily fix the back surface side with a strong fixing force by driving the staple 1 against the wall of the room. Can be pasted on. Further, when peeling from the wall surface, it is only necessary to pull out the staple 1 from the wall surface, and since only a minute needle hole that can be found by gazing remains on the wall surface, the appearance is not impaired.

  In the present invention, the staple 1 used for fixing one surface of the adhesive tape is generally widely used as a stationery, and its operation is very simple by simply pushing the handle. There is no. The staple 1 is fixed to the wall surface by the staple 1 after the handle and the clincher arm of the stapler are opened at approximately 180 degrees, and then the handle is pressed from the front side so that the adhesive tape is pressed against the wall surface by the protruding portion of the staple 1 on the back side of the handle. In the case of a slightly soft wall material in which the staple 1 can be driven, such as gypsum board, the adhesive tape can be fixed easily and firmly by driving the staple 1.

  The adhesive tape base material 2 is made of a slightly soft synthetic resin material, paper, cloth, etc. that can be penetrated by the staple 1, and the adhesive portion 4 is coated with the adhesive 3 on the base material 2 as in the conventional example. The staple driving unit 5 can be formed by forming a region where the adhesive 3 is not applied on the surface of the substrate 2, that is, without applying the adhesive 3. It can be formed by providing a region where the two surfaces are exposed. Thus, by forming the adhesive portion 4 and the staple driving portion 5 by dividing the surface of the base material 2, it is possible to easily drive the staple 1 without being disturbed by the adhesiveness, and the staple driving portion. 5 can be clearly distinguished visually from the adhesive portion 4.

  Further, by forming the adhesive portion 4 and the staple driving portion 5 on the surface of the base material 2, the protruding height of the adhesive 3 from the surface of the base material 2 is higher than the thickness of the shoulder 1 a of the staple 1. By doing so, it is possible to prevent the staple 1 driven into the base material 2 from interfering with an object to be fixed to the wall surface of the poster or the like described above, and the fixing force by the adhesive portion 4 can be increased. Further, even if the object to be fixed to the wall surface is a plastic such as a poster, the interference with the staple 1 is prevented, so that the shoulder 1a of the staple 1 protrudes from the surface by the pressing force at the time of adhesion. There is no such thing as being projected in a shape.

  The substrate 2 can be formed of paper or cloth as described above. However, if the substrate 2 is formed of a synthetic resin material having an appropriate rigidity, it is loaded by driving a plurality of staples 1, 1,. It is possible to disperse the load, and it is possible to easily increase the support load on the wall side even with a wall material such as the above-described gypsum board. When a plurality of staples 1, 1... Are formed in such a manner that they can be driven, the narrow band-shaped staple driving portions 5 are formed on both side edges of the base material 2 with the adhesive portion 4 interposed therebetween. By making the staple 1 driven in along the edge of the base material 2, the surface of the base material 2 can be effectively used to easily improve the fixing property by the staple 1 and the adhesive property by the adhesive part 4. .

  Further, it is desirable to cover the surface of the adhesive portion 4 with a release paper 6 in order to facilitate carrying and the like. The release paper 6 is not limited to paper, and any suitable material that can be easily peeled off when used, such as a synthetic resin film.

  As is clear from the above description, according to the present invention, it is possible to provide a pressure-sensitive adhesive tape that can increase the fixing force to the wall surface, has excellent removability, and does not impair the appearance of the wall surface when peeled off. Therefore, the utility value of the wall surface can be increased.

  1 and 2 show an embodiment of the present invention. In this embodiment, as shown in FIG. 1A, the adhesive tape 11 has an adhesive part 4 and a staple driving part 5, and is made of PET (polyethylene terephthalate) having a relatively high rigidity in a strip shape. The pressure-sensitive adhesive 3 is applied to the surface of the base material 2 to be formed. The base material 2 may be colorless and transparent in which the back side is seen through or colored in consideration of appearance, etc., so that the staple 1 whose leg portion 1b is less than 5 mm can penetrate deeply, for example It is formed to a thickness of about 0.3 mm, and can be easily hidden behind a fixed object 13 to the wall surface 12 such as a thermometer or the like in addition to a poster, a frame, a clock, etc. For example, it is formed in a width dimension of about 40 mm.

  The pressure-sensitive adhesive portion 4 is formed by applying a pressure-sensitive adhesive 3 made of an appropriate resin such as acrylic on the surface of the base material 2, and is formed on the surface opposite to the base material 2 of the layered pressure-sensitive adhesive 3, that is, on the surface side As shown in FIG. 1B, a release paper (release paper 6) made of a film-like resin that can be easily peeled off during use is attached. The pressure-sensitive adhesive 3 and release paper 6 are appropriately colored so that they can be distinguished from the base material 2 and each. The layered pressure-sensitive adhesive 3 has a thickness of 0.3 mm as shown in FIG. It is laminated on the surface of the base material 2 with a height dimension L2 of about 0.5 mm so as to be higher than the thickness dimension L1 of the shoulder 1a of the staple 1 which is about the same. This layer-like pressure-sensitive adhesive 3 is formed in a strip shape along the longitudinal direction at the center of the strip-shaped substrate 2, and staple driving portions 5 are arranged on both sides.

  The staple driving unit 5 is formed by an exposed area on the surface of the base material 2 to which the adhesive 3 is not applied, so that the staple 1 can be driven along the longitudinal direction of the base material 2, that is, the shoulder 1a of the staple 1 is used as the base material. 2 is formed in a narrow band shape having a width dimension of about 7 mm so as to be easily driven along the longitudinal direction of 2.

  Therefore, for example, when fixing the timepiece 13 to the wall surface 12 made of gypsum board as shown in FIG. 2, after cutting into pieces 11a having an appropriate length enough to satisfy the load-bearing ability of the adhesive portion 4 by a scissors or the like. First, positioning is performed so that the back surface of the substrate 2 is aligned with the wall surface 12, and then, the staple 1 is driven into the staple driving unit 5 to be fixed to the wall surface 12. At this time, as described above, the staple 1 penetrates through the thin base material 2 and pierces deeply into the wall surface 12, firmly holds the base material 2 between the shoulder portion 1a and the wall surface 12, and is firmly fixed by the leg portion 1b. And support vertical load. As shown in FIG. 2, if the staples 1 are driven into the staple driving portions 5 disposed above and below the adhesive portion 4 with the individual pieces 11 a facing sideways, a plurality of staples are formed due to the rigidity of the base material 2. The load can be dispersed and supported on the legs 1b, 1b,... Of the staple 1, the load applied to each leg 1b of the staple 1, and the corresponding portion of the wall surface 12 that supports the load. Each support load can be reduced to prevent the staple 1 from being removed from the wall surface 12 and the corresponding portion of the leg 1b or the wall surface 12 of the staple 1 can be prevented from being deformed. It becomes.

  After fixing the timepiece 13 to the wall surface 12, the release paper 6 is peeled off as shown in FIG. 2A, and the timepiece 13 is exposed on the surface of the layered adhesive 3 exposed as shown in FIG. Complete by pasting the back side of. As described above, the layered pressure-sensitive adhesive 3 having a protruding dimension L2 from the surface of the base material 2 larger than the thickness dimension L1 of the shoulder part 1a of the staple 1 is formed between In order to prevent the contact between the staple 1 and the timepiece 13 at the time of pasting, the adhesion failure due to the contact between the staple 1 and the timepiece 13 is not caused.

  Further, when the timepiece 13 is removed from the wall surface 12, first, the adhesive strength of the adhesive 3 is stronger than the fixing strength of the staple 1 to the wall surface 12, so if the timepiece 13 is pulled horizontally from the wall surface 12 together with the adhesive tape 11. Then, the timepiece 13 is peeled off from the base material 2 against the adhesive force of the adhesive 3 by using a spatula or the like as appropriate. After removing the base material 2, holes formed by the leg portions 1 b of the staple 1 remain on the wall surface 12. However, since the holes are extremely small, it is difficult to visually recognize the appearance of the wall surface 12. Absent.

  In the above embodiment, a case where a single staple 1 is driven into each staple driving unit 5 has been described. However, one staple driving unit 5 corresponds to the weight of an object 13 such as a watch. It is also possible to drive the staples 1 only into the staples, or to drive a plurality of staples 1, 1... Into the staple driving unit 5. Moreover, you may make it support the load of the single to-be-fixed object 13 with the several piece 11a, 11a .... Furthermore, as shown in the conventional example, it is also possible to improve the removability of the poster or the like by coating the adhesive 3 with a removable resin. In addition, when the base material 2 is made of PVC (polyvinyl chloride), it is possible to increase the stability at the time of fixing on the uneven wall surface 12 due to its flexibility. The load carrying capacity can be further increased by using a stainless steel one instead of the one made.

  FIG. 3 shows another embodiment of the present invention. In this embodiment, the same components as those in the above-described embodiment are denoted by the same reference numerals in the drawing, and the description thereof is omitted. As shown in FIG. 3 (a), in this embodiment, the surface of the substrate 2 is divided into three strips 3A, 3B, and 3B in the width direction along the longitudinal direction, and the adhesive 3 is formed in a narrow band shape. The stapling portion 5 is applied, and two streaks are formed between the strips 3A and 3B of the pressure-sensitive adhesive 3 in a narrow band shape.

  The strip 3A of the pressure-sensitive adhesive 3 disposed in the center is formed to be slightly wider than the other strips 3B and 3B in consideration of the adhesion balance, and covers the surface of all the layered pressure-sensitive adhesives 3 of the substrate 2. A release paper 6 with an appropriate colored and transparent color is applied so as to cover the entire surface. The release paper 6 is formed by uniaxially stretched film or by performing appropriate resin laminating on the film, and is easy to tear along the longitudinal direction of the substrate 2. In this embodiment, a highly adsorbing sheet material 14 having a large number of fine closed cells formed by foaming a synthetic resin material is bonded and fixed to the back surface of the substrate 2.

  Therefore, when the staple 1 is driven in the vertical direction with respect to the wall surface 12 from the transparent release paper 6 to the staple driving unit 5, the staple 1 is driven into the wall surface 12 by the thickness of the release paper 6 and the sheet material 14. Although the depth becomes shallower, the base material 2 is firmly fixed to the wall surface 12 by the adsorption effect of the sheet material 14 that adheres strongly to the wall surface 12 by driving the staple 1. Next, as shown in FIG. 3 (b), when the release paper 6 is peeled from the longitudinally separated pieces 11a in the vertical direction, the release paper 6 is torn by the staple 1 in which the release paper 6 is driven, and depending on the properties of the uniaxially stretched film. The adhesive is peeled off from the surface of the pressure-sensitive adhesive 3 so as to extend a tear on the staple driving unit 5. Thereafter, the fixing work is completed by attaching the watch 13 (not shown) with the adhesive 3 exposed without covering the tear mark 6a of the release paper 6.

  In addition, when the fixing force to the wall surface 12 can be ensured in the other embodiments described above, the sheet material 14 can be omitted, and the fixing force is applied in the above-described embodiment using the sheet material 14. The sheet material 14 may be made of a material that exhibits a frictional force. Furthermore, in the above embodiment, when the protruding height of the adhesive 3 from the surface of the base material 2 is made higher than the thickness of the shoulder 1a of the staple 1, the interference between the staple 1 and the fixed object 13 is prevented. However, if at least these dimensions are the same, the staple 1 does not hinder adhesion.

It is a figure which shows this invention, (a) is a perspective view, (b) is a principal part expanded sectional view. It is a figure which shows the fixed state to the wall surface 12, (a) is a perspective view, (b) is a principal part expanded sectional view. It is a figure which shows other embodiment of this invention, (a) is a perspective view, (b) is a figure explaining the state at the time of peeling the release paper 6 in the fixed state to the wall surface 12.
