Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a cutter assembly for a tape holder that is used with various adhesive tapes attached thereto.

Prior Art Various tape holders are known that are equipped with a reel for attaching adhesive tape such as cellophane tape and a cutter for cutting the tape. However, all of the cutters conventionally attached to commercially available tape holders are made by cutting the tip of a flat metal plate into a wave shape to form teeth, as described in, for example, Japanese Utility Model Application Publication No. 49-30390. Depending on the type of adhesive tape, it may not be possible to cut sharply unless the tape is stretched unduly, or the tape may have streaks.

Therefore, Japanese Utility Model Application Publication No. 56-58758 discloses that the cutter blade is formed with a special arc-shaped recess so that it can cut adhesive tapes, cloth, etc., but only the upper edge of the flat plate is cut. It is industrially difficult to transform in this way, and it cannot be put to practical use. In addition, in Japanese Utility Model Application Publication No. 59-93896, the cutting blade has a triangular wavy uneven shape on the straight width surface, a needle-like burr blade is formed at the tip of the triangle, and the left and right chevron-shaped equal sides are used. A cutting blade having a blade shape with a secondary burr edge formed on the cutting edge is disclosed, but not only is it difficult to form the burr edge uniformly, but such a cutting blade with the burr edge standing upright on the cutting edge is not normally used. It cannot be used by attaching it to a tape holder.

Purpose of the invention The present invention is a cutter assembly that can be easily attached to a regular tape holder and used stably, is easy to manufacture, and is durable enough to cut any adhesive tape sharply. The purpose is to provide a cutter assembly that is easy to handle.

Structure of the invention The cutter assembly of the invention, as shown in the examples shown in FIGS. 1 and 4, is a metal corrugated plate 1 having 4 to 10 irregularities per cm along a line perpendicular to the irregularities. A tooth plate 3 with wave-shaped teeth 2 formed by diagonally grinding or cutting is fixed to a holder 4,
The holder 4 holds the toothed plate 3 between the front plate 5 and the rear plate 6, and the wave-shaped teeth 2 protrude from the upper end of the front plate 5, and the upper part of the rear plate 6 meets the toothed plate 3. After being bent to form a groove 7 between them, the cross-sectional shape becomes an inverted U-shape or a J-shape, and the chevron-shaped portion 8 at the upper end of the rear plate 6 is approximately at the same height as the tip of the wave-shaped tooth 2. It is characterized by being bent so that

That is, the cutter assembly of the present invention has a cutter mounting base 11 of a tape holder 10 as shown in FIG.
It is used to cut the adhesive tape 13 attached to the reel 12 by fitting the chevron-shaped portion 8 of the rear plate 6 to the cutter, that is, the corrugated plate 1 as the tooth plate 3. Therefore, the tooth plate 3 has strong strength and is durable without being easily deformed.
Moreover, the corrugated plate 1 has moderate unevenness at the tip of the tooth plate 3.
Because the wave-shaped teeth 2 are formed by grinding or cutting diagonally along a line perpendicular to the unevenness (see Figures 2 and 3), the tip angle of the teeth 2 is different from the density of the teeth, that is, the unevenness. It can be formed very sharply considering its density, and any type of adhesive tape 13 can be cut accurately. Furthermore, the tooth plate 3 is stably held between the front plate 5 and the rear plate 6 of the holder 4 with the teeth 2 protruding, and the rear plate 6 is spaced apart from the tooth plate 3 by the tips of the teeth 2. Since it has a stable chevron portion 8 at approximately the same height as the tooth 2 (preferably slightly higher than the tip of the tooth 2), it will not be easily damaged even if you carelessly touch the tooth 2 portion, and using this chevron portion 8 as a fulcrum. Since the tape 13 can be efficiently cut with the teeth 2, the tape 13 will not be damaged or stretched during cutting.

The holder 4 may consist of a front plate 5 and a rear plate 6 that hold the tooth plate 3 with the side surface of the tooth plate 3 exposed on the side as shown in FIG. 2, but as shown in FIG. Preferably, a side wall 9 is provided to cover the side surface of the tooth plate 3 so as not to be damaged by the exposed teeth 2. In this case, it is preferable that the side surfaces 9 are formed by bending both sides of the front plate 5 of the holder 4, and the height of the side walls 9 is determined by the height of the side walls 9.
It is preferable that the upper end of the wavy tooth 2 is formed so as to protrude above the tip of the wavy tooth 2.

The holder 4 shown in FIG. 1 having the side wall 9 can be attached to any tape holder 10 with good appearance and stability, but the holder 4 shown in FIG. 2 without the side wall 9 can be attached to a cutter as shown in FIG. 1 unit
It is preferable to attach the tape holder 10 to a tape holder 10 which is formed high so that both sides 14 of the tape holder 1 cover the teeth 2.

In addition, in the present invention, the corrugated plate 1 used as the tooth plate 3 has a parallel angular waveform with a height of 1 to 3 mm and b unevenness width, that is, a pitch of 2.5 to 1 mm (preferably about 1.4 mm). Preferably, the teeth 2 are formed by grinding or cutting the corrugated plate 1 obliquely along a line perpendicular to the irregularities so that the tips of the teeth form an acute angle with the back surface of the tooth plate.

Effects of the Invention The cutter assembly of the present invention can be easily attached to the tape holder 10 because the tooth plate 3 and its holder 4 are integrally formed. Further, since the tooth plate 3 is made of the corrugated plate 1, the tooth plate 3 has strong strength and can be used with good durability. Furthermore, since the teeth 2 are constructed by grinding or cutting the corrugated plate 1 diagonally, the teeth 2 can be extremely sharp while maintaining appropriate tooth density, that is, unevenness density.
It can stably cut any kind of tape. In addition, behind the tooth 2, there is a tooth plate 3.
As a part of the holder 4 is formed with a chevron portion 8 having almost the same height as the tip of the tooth 2, it is easy to cut the tape using the chevron portion 8 as a fulcrum, and the cutter assembly of the present invention does not cut the tape improperly. Cuts tape very efficiently and accurately without stretching or damaging the tape.
