Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape cutter, and more particularly, to a tape cutter for pulling out and cutting a predetermined length of an adhesive tape wound in a roll shape, for example.

[0002]

2. Description of the Related Art In general, a tape cutter of this type includes a tape support for rotatably and detachably supporting an adhesive tape wound in a roll shape, and an adhesive tape positioned in front of the tape support. And a cutting portion provided with a cutter for cutting the drawer portion. In addition, this type of tape cutter fills the inside of the cutter body with, for example, iron, a metal other than iron, sand or concrete, and pulls out the adhesive tape with one hand and cuts it with a cutter. It is stabilized so that it does not move on a workbench or the like.

[0003] However, in the case where the heavy material such as iron or concrete is filled in the inside of the cutter body as described above, the material cost increases because the important thing such as iron or concrete is filled in the cutter body. There is a problem that it takes time to assemble. In addition, since the weight increases, when transporting a large amount of tape cutter, there is a problem that the distribution cost increases, and also, when it is accidentally dropped from a desk or the like,
Due to the high impact, there was a danger of damage to surrounding objects and injury to the feet.

Therefore, conventionally, an adhesive resin layer as an adhesive fixing means that can be repeatedly adhered is integrally formed on the bottom surface of the cutter body, and for example, the cutter body is fixed on the upper surface of the desk by the adhesive force of the adhesive resin layer. The adhesive tape can be pulled out and cut (Japanese Utility Model 5-3004).
No. 9, JP-A-5-16766, etc.). According to this structure, the size and weight of the tape cutter can be reduced,
Further, effects such as being convenient to carry are obtained.

[0005]

However, in the above structure, since the adhesive resin layer is fixed to the bottom surface of the cutter body by adhesion or the like, the adhesive resin layer is fixed to an adhered surface such as a desk top surface or a work table surface. However, when the adhesive resin layer is detached again from the adhered surface, the adhesive resin layer may be peeled off from the bottom surface of the cutter body and remain on the adhered surface side, which has a problem that repeated use is hindered.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and achieves light weight and miniaturization, securely adheres an adhesive fixing means to a cutter body, and repeatedly repeats fixing and re-peeling of a tape cutter to an adhered surface. It is an object of the present invention to provide an enabled tape cutter.

[0007]

In order to achieve the above object, a tape cutter according to the present invention comprises a tape support for rotatably and detachably supporting an adhesive tape wound in a roll shape, A cutter body having a cutting portion provided at the front of the section and having a cutter for cutting the drawn-out portion of the adhesive tape, and adhesive fixing means formed at least at two front and rear positions on the bottom surface of the cutter body. In the tape cutter, the cutter body comprises a hollow base having a hollow portion in the entire inside thereof and having an open lower surface, and a bottom plate closing a lower surface opening of the hollow base. It is characterized by being formed of a double adhesive layer that can be repeatedly bonded to each other through a through hole provided in the bottom plate (claim 1).

In the present invention, the double pressure-sensitive adhesive layer is
For example, it can be formed of a polystyrene-based adhesive gel sheet (claim 2). In this case, the composition of the polystyrene-based gel sheet is styrene-based elastomer / hydrogenated resin / paraffin-based oil = 100/50 to 150/5.
A composition ratio of 0 to 300 is preferred. (Here, the composition ratio is shown in parts by weight.) Here, as the styrene-based elastomer, styrene-ethylene-propylene-styrene block copolymer rubber, styrene-ethylene-butylene-styrene copolymer rubber, SBR And hydrogenated rubber. Examples of the hydrogenated resin include hydrogenated alicyclic resins, hydrogenated styrene-terpene copolymer resins, and hydrogenated petroleum resins. As paraffin oil, liquid paraffin, paraffin mineral oil,
Paraffin wax or the like can be used as needed. A preferred example is styrene-based elastomer / hydrogenated petroleum resin / liquid paraffin = 100/100/100. In addition, as the adhesive gel, in addition to a polystyrene-based adhesive gel, an adhesive based on a polyethylene-based, polyolefin-based polymer, or an elastomer can also be used.

According to the tape cutter of the present invention configured as described above, the adhesive fixing means is formed of a double adhesive layer that can be repeatedly bonded to each other through a through hole provided in the bottom plate. By doing so, in addition to the adhesive force of the outer pressure-sensitive adhesive layer exposed to the outside and adhered to the adherend surface, in addition to the adhesive force of the outer pressure-sensitive adhesive layer to the lower surface of the bottom plate, the outer pressure-sensitive adhesive layer and the inner pressure-sensitive adhesive layer Since the fixing force formed by connecting the two through the through hole of the bottom plate is stronger, there is no danger that the adhesive fixing means, that is, the double adhesive layer, will be peeled off from the tape cutter. Therefore, the tape cutter can be repeatedly fixed to the surface to be adhered and peeled again, and the adhesive tape can be pulled out and cut.

In addition, since the cutter body can be fixed to the surface to be adhered by the adhesive fixing means, there is no need to fill the inside of the cutter body with a heavy material such as iron or concrete. Since it can be formed of a synthetic resin member, the appearance can be improved. Also,
By eliminating the need for filling with the heavy object, the cutter body is constituted by a hollow base having a hollow portion in the entire interior thereof and having an open lower surface, and a bottom plate closing the lower opening of the hollow base. In addition, the cutter body can be made lightweight and small. Therefore, the number of constituent members can be reduced, and the assembling process can be facilitated. Further, the transportation cost can be reduced. Furthermore, it is convenient to carry and
There is little damage due to falling or the like, and there is no risk of damage to surrounding objects and injuries to feet due to falling. Furthermore, by molding the cutter body with translucent or transparent plastic,
The aesthetic appearance of the cutter can be enhanced, and the cutter can have a unique design because it can be seen even when a liquid such as water or a small object such as a doll is put into the hollow portion of the cutter body.

FIG. 1 is a side view showing an example of the tape cutter of the present invention, FIG. 2 is a bottom view of FIG. 1, FIG. 3 is a sectional view of the tape cutter, and FIG. FIG.

The tape cutter includes a tape supporting portion 10 rotatably and detachably supporting the adhesive tape 1 wound in a roll shape, and a drawing portion of the adhesive tape 1 positioned in front of the tape supporting portion 10. A cutter body 30 having a cutting portion 20 having a cutter 2 to be cut, and adhesive fixing means 4 formed at least at two front and rear positions (two cases are shown in the drawing) on the bottom surface of the cutter body 30.
0 constitutes a main part.

The cutter main body 30 has a hollow portion 31 made of plastic having a hollow portion 31 in the entire inner region and having an open lower surface, and a bottom plate 34 made of plastic that closes an opening 33 on the lower surface of the hollow base 32. It is composed of

In this case, the tape supporting portion 10 provided on the hollow base 32 is substantially composed of a rear wall 11 which protrudes in an arc shape toward the rear side, and a pair of side walls 12 which are continuous on both sides of the rear wall 11. Support grooves 13 are provided on the opposite surfaces of the side walls 12 so as to protrude in a U-shape and support the reel 3 for detachably holding the adhesive tape 1 in a vertically rotatable and detachable manner. As shown in FIG. 3, the support groove 13 includes a vertical groove 14 having an upper end opening at an upper portion, and a locking groove 15 which is connected to the lower end of the vertical groove 14 and bends with a gentle downward slope. It is composed of In addition,
The tip of the locking groove 15 is formed in a semicircular shape, and the reel 3
Shaft 4 is rotatably supported.

The cutting portion 20 has an arcuate top on both sides and a flat protuberance at the middle, and an intermediate flat portion 21 has a substantially l-shaped vertical portion of the cutter 2 bent. A mounting groove 22 into which the piece 2a is inserted is provided.

As described above, as shown in FIGS. 3 and 4, the entirety of the hollow base 32 having the tape supporting portion 10 protruding substantially in a U-shape at the rear portion and the cut portion 20 protruding at the front portion. It is formed to have the same thickness, and a hollow portion 31 is formed by a hollow portion in the entire inner region. Therefore, the entire material of the hollow base 32 can be reduced, and the weight can be reduced as much as possible.

In order to attach the bottom plate 34 to the opening 33 of the hollow base 32, an engaging projection 35 projecting from each side of the bottom plate 34 and a side of the opening 33 are provided. The engaging recess 36 is engaged and fixed by bonding or the like.

On the other hand, the above-mentioned adhesive fixing means 40 is shown in FIG.
(B), as shown in FIG. 3, FIG. 5, and FIG.
4 are formed at the front and rear portions, and the rear portion is formed to have a larger area than the front portion. As described above, the reason for increasing the area of the rear adhesive fixing means 40 with respect to the front adhesive fixing means 40 is that when the adhesive tape 1 is pulled out and cut, a large load is applied to the rear part compared to the front part. It is. Further, the respective adhesive fixing means 40 can be repeatedly adhered to each other through a plurality of (four in the drawing, shown in the drawing) elongated holes 50 provided at the front and rear portions of the bottom plate 34, respectively. The double pressure-sensitive adhesive layers 41 and 42 have a substantially rectangular shape. That is, the outside pressure-sensitive adhesive layer 41 disposed outside the bottom plate 34 and the inside pressure-sensitive adhesive layer 42 disposed inside the bottom plate 34 (hollow portion side) are combined with the connection pressure-sensitive adhesive layer disposed in the through-hole 50. 43 are firmly connected. In this case, the double pressure-sensitive adhesive layers 41 and 42 are made of a polystyrene-based pressure-sensitive adhesive gel sheet, specifically, a styrene-ethylene-butylene-styrene block copolymer / hydrogenated alicyclic resin / liquid paraffin = 100/100/100. (The ratio is shown in parts by weight). As described above, in order to form the adhesive fixing means 40 by the double adhesive layers 41 and 42, the bottom plate 34 in which the through holes 50 are previously formed is inserted into a mold, and the through holes 50 on both sides of the bottom plate 34 are inserted. Can be molded by a double molding method (double molding method) in which a fluid pressure-sensitive adhesive raw material comprising the above composition is poured into a mold provided around the periphery of the composition and heated to form the composition.
