Description

  The present invention relates to a tape dispenser, a cutting blade for a tape dispenser, and a tape cutter, and more particularly to a structure of a blade that presses and cuts an adhesive tape.

  Adhesive tape is widely used today as an adhesive means that can fix an object simply and immediately. For example, in general households and offices as office supplies and packing equipment, or for industrial use, for example, to fix wiring boards and module parts in the manufacturing process of electronic and electrical equipment, and to install interior parts of automobiles or civil engineering construction sites Is used in various applications and situations, such as pasting boards and components.

  Such an adhesive tape is provided with a pressure-sensitive adhesive on one or both sides of a tape base material made of resin, cloth, paper, etc., and is generally provided as a tape roll wound in a roll shape. In addition, such a tape roll may be provided with a cutter that can be attached to the tape roll and cut the tape to a desired length as an accessory or as an optional tool. Furthermore, various dispensers are also provided that contain a tape roll and have a blade for cutting the tape into a desired length (see, for example, the following patent document).

Japanese Patent Laid-Open No. 7-252010 JP 2001-187668 A

  By the way, in order to cut | disconnect a tape reliably, the said conventional tape cutter generally has a resin-made or metal-made blade in a jagged (sawtooth shape) shape as shown in FIG. For this reason, the edge of the cut tape becomes jagged corresponding to the shape of the blade, and the appearance of the tape is poor, and the adhesive strength of the edge of the tape is difficult to be lowered.

  In fact, after cutting the tape to an appropriate length with a dispenser blade in an office, etc., the edge of the tape may be cut cleanly (straightly) again to remove the cut end of the tape. . In addition, in the production site of various industrial products such as factories, tape is applied without leaving the edge of the member to be adhered, and the adhered tape is gradually peeled off from the end when the product is used over time. In order to prevent such a situation, there is a case where a tape or a cutter is used to cleanly cut the end of the tape into a straight line when bonding the tape, and there is room for improvement in terms of workability.

  On the other hand, some of the above-mentioned tape dispensers can cut the tape in a straight line without the cut edge being jagged. However, the conventional dispenser generally has a complicated mechanism, is expensive as compared with the tape body, and has a difficulty in lacking simplicity.

  Furthermore, not only tapes with adhesives, but also various products (such as aluminum foil, wrap, toilet paper, etc.) that are provided by rolling a long material into a roll shape in the same manner as adhesive tapes. These are also collectively referred to as “tape”, but these also need to be cut to the desired length when used in the same way as adhesive tape, and conventional cutters are often equipped with jagged edges. Then, there is a similar problem that the cut edge becomes jagged.

  Therefore, an object of the present invention is to enable the tape to be cut linearly with a simple mechanism.

  In order to solve the above-mentioned problems and achieve the object, a tape dispenser according to the present invention is a tape roll holding unit that holds a tape roll in which the tape is wound in a roll shape so that the tape roll can be rotated and pulled out of the tape roll. And a tape cutting part that includes a cutting blade capable of cutting the tape by pressing the tape, and a tape cutting part that cuts the tape drawn from the tape roll stored in the tape roll holding part by the cutting blade. It is a dispenser, and the cutting blade has a blade edge portion including a blade edge extending in a substantially linear shape capable of pressing the tape drawn out from the tape roll, and at least one end portion of the blade edge portion. A cut can be formed in the side edge of the tape by pressing the side edge of the tape drawn from the tape roll. With a cut-out portion.

  In order to cut the tape in the tape dispenser of the present invention, the tape is pulled out from the tape roll stored in the tape roll holding part to the tape cutting part, and the tape is put on the cutting blade in the same manner as in this type of conventional tape dispenser. This can be cut by pressing, but in the dispenser of the present invention, the cutting blade has a cutting edge portion including a cutting edge extending substantially linearly, and a notch is formed at the end of the cutting edge portion. It has.

  When the tape is pressed against the blade edge, the notch portion is a portion in which the side edge portion of the tape comes into contact and tears the side edge portion of the tape to form a cut in the tape side edge portion. Once the cut is formed in the tape side edge, the tape is easily cut along the cutting edge by further pressing the tape against the cutting edge.

  As a specific shape of the cutout portion, for example, a shape having a substantially semicircular shape, that is, a shape in which the blade edge portion is cut out in a substantially semicircular shape can be used. Moreover, it is good also as what makes | forms a dominant arc (arc larger than a semicircle) shape, or an inferior arc (arc smaller than a semicircle) shape. Further, other than the circular arc, for example, an elliptical arc shape, a square shape, a triangular shape (V shape), a polygonal shape, and other shapes can be used.

  However, the corner of the notch at the center of the cutting blade (hereinafter referred to as “inner corner” or “cutting edge”) is sharp or has a right angle or an acute angle smaller than the right angle. Thus, forming the notch (for example, if the notch is semicircular as described above, the notch is a right angle, and if it is a dominant arc shape, the notch is an acute angle) This is preferable in that the side edges can be cut more reliably and easily.

  Note that the “notch” portion referred to in the present invention does not limit the method of creation (not limited to the one formed by cutting out or cutting the cutting blade), and the method of forming the notch portion is particularly It doesn't matter. For example, it is of course possible to form the cutout portion simultaneously with the cutting blade (blade edge portion) by integral molding. In particular, when the blade according to the present invention is made of resin, the dispenser according to the present invention can be manufactured at a low cost with good mass productivity by integrally forming the main body of the dispenser and the cutting blade.

  Although the said notch part may be provided in the one end part of a blade edge | tip part, it is desirable to provide in the both ends of a blade edge | tip part, ie, the position corresponding to the right-and-left both sides edge of a tape, respectively. If it does in this way, it will become possible to cut a tape from both the right and left edge parts of a tape, and operativity will become good. Thus, when providing notches at both ends of the blade edge, the notches are spaced apart from each other so that the left and right edges of the tape stored in the tape roll holder are positioned within the left and right notches. Can be arranged. In other words, the distance between a pair of (two left and right) cutting edges (inner corners) provided in the cutting edge is smaller than the width of the tape, and the distance between the outer edges of the pair of notches is the width of the tape. Both notches are formed so as to be larger.

  The blade edge portion has a first surface located on the side closer to the tape roll and a second surface located on the side far from the tape roll, and the first surface and the second surface intersect each other. Thus, it is desirable that the cutting edge is formed, and the cutting blade is provided so that an angle formed between the first surface and the tape drawn from the tape roll is 0 degree or more and less than 90 degrees. This is to cut the tape more easily and reliably.

  In other words, the first surface faces the tape roll side and the second surface faces the opposite side of the tape roll. In other words, the second surface faces the direction of travel of the tape fed out from the tape roll, and the first surface faces the direction opposite to the travel direction of the tape.

  The angle formed by the first surface and the second surface may be smaller than 90 degrees, and a single blade may be formed by the first surface and the second surface. The cutting blade may be a plate-like member (thin plate). In this case, one surface (surface near the tape roll) of the plate member is the first surface, and the other surface (surface far from the tape roll) is the second surface.

  In the dispenser of the present invention, a guide part may be provided outside the notch part to regulate the positional deviation of the tape drawn from the tape roll in the left-right direction and guide the side edge of the tape to the notch part. This is because the tape drawn from the tape roll can be more easily guided to the notch and can be cut to improve the convenience of the dispenser.

  In order to further improve the operability, the guide portion may protrude upward from the blade edge. In addition, it has notches at both ends of the cutting edge, and is provided with the above-mentioned guide parts so as to stand on the outer sides of these notches, and the tape drawn from the tape roll is dropped between the guide parts to the cutting edge. It may be possible to press the tape.

  Moreover, it is good also as a shape which curved the inner wall part of the said guide part in the arc shape. If the inner wall portion of the guide portion is formed in an arc shape in this way, even if the tape pulled out from the tape roll is moved up and down along the guide portion, the edge of the tape is caught or bent by contacting the inner wall portion of the guide portion. It is possible to prevent such a situation from occurring.

  Furthermore, in the dispenser, a pedestal-shaped tape locking portion that allows the tape drawn from the tape roll to be temporarily attached to a position before the blade edge portion as viewed from the tape drawing point side of the tape roll. May be further provided. According to such a structure, the next time the tape is used, the tape can be easily pulled out by pinching the tape stopped by the tape locking portion.

  Further, the cutting blade for a tape dispenser according to the present invention includes a tape roll holding unit that holds a tape roll in which the tape is wound in a roll shape so that the tape roll can be rotated and pulled out from the tape roll, and the tape is cut. A cutting blade for a tape dispenser, which is attached to a tape dispenser having a tape cutting portion for cutting the tape and cuts the tape, a cutting blade capable of cutting the tape drawn from the tape roll, and the cutting blade is cut into the tape The cutting blade has a cutting edge portion including a cutting edge that extends substantially in a straight line capable of pressing the tape drawn from the tape roll, and at least of the cutting edge portion. By pressing the side edge of the tape drawn from the tape roll on one end, a cut can be formed in the side edge of the tape. With a cut-out portion.

  The cutting blade for a tape dispenser of the present invention can be attached to an existing tape dispenser to cut the tape in a straight line, and the cutting blade similar to the dispenser of the present invention, that is, a substantially straight line. A blade having a cutting edge and a notch is provided, and the blade is fixed to an existing tape dispenser by the fixing portion.

  The fixing method (fixed part structure) is not particularly limited. For example, it may be fixed to an existing dispenser by fitting, bonding, covering and mounting, or other fixing structures.

  Furthermore, the tape cutter according to the present invention is a tape cutter for cutting a tape drawn from the tape roll by attaching the tape to a tape roll wound in a roll shape, and capable of cutting the tape drawn from the tape roll. A cutting blade and a base portion that supports the cutting blade on the tape roll so as to be movable along the peripheral surface of the tape roll, and the cutting blade presses the tape drawn from the tape roll. It has a cutting edge part including a cutting edge extending in a substantially straight line, and the side edge part of the tape by pressing the side edge part of the tape pulled out from the tape roll against at least one end part of the cutting edge part. A notch that can form a notch.

  The tape cutter of the present invention can be attached to the tape roll itself and cut the tape with the cutting blade. The cutting blade has a structure similar to that of the dispenser of the present invention (including a substantially straight blade tip and a notch), and the base moves the cutting blade along the peripheral surface of the tape roll. Support as possible. Thereby, the tape of desired length can be pulled out from a tape roll, and this can be cut | disconnected by the said cutting blade.

  The tape roll holding unit 12 includes a support shaft 13 extending horizontally at the center thereof, and the tape roll 1 is rotatably supported by passing the core through the support shaft 13. Also, one side plate 15a of the dispenser 11 is removable, and in order to attach the tape roll 1 to the tape roll holding part 12, the side plate 15a (12a, 20a) of the dispenser 11 is removed, and the tape roll 1 The tape roll 1 can be stored in the tape roll holding part 12 by passing the core through the support shaft 13. The tape roll holding part 12 and the arm part 20 may have the same structure as a conventional tape dispenser.

  On the other hand, the tape cutting unit 21 includes a cutting blade 31 that can be cut by pressing the tape 10, and a pedestal tape locking unit 22 for temporarily attaching the tape 10, and the tape roll holding unit 12. The tape locking part 22 and the cutting blade 31 are arranged in this order in the feeding direction of the tape 10 when viewed from the side, and the tape 10 is pulled out from the tape roll 1 and attached to the tape locking part 22 to lock the tape 10. Thereafter, the tape 10 can be cut by pressing the tape 10 against the cutting blade 31.

  The cutting edge 31c of the cutting blade 31 has a first surface 31a located on the side close to the tape roll (tape roll holding unit 12) and a second surface 31b located on the side far from the tape roll (tape roll holding unit 12). It is formed by intersecting with an acute angle (for example, a range of 25 ° to 50 °) (see FIG. 6). The first surface 31a of the cutting blade 31 faces (faces) diagonally (with an acute angle) to the adhesive surface of the lower surface of the tape drawn from the tape roll. Therefore, when the tape is cut, the tape is stuck and fixed to the tip portion of the first surface 31a of the cutting blade 31, whereby the tape is cut cleanly along the blade edge 31c.

  The cutting edge 31c of the cutting blade 31 extends horizontally and linearly at the upper end of the front surface of the tape cutting portion 21, and has notches 32a and 32b at the left and right ends. These notches 32 a and 32 b are formed at an interval corresponding to the width of the tape 10 accommodated in the tape roll holder 12. More specifically, as shown in an enlarged view in FIG. 10, the left and right side edges 10a and 10b of the tape 10 are located in the left and right cutouts 32a and 32b (the cutting blade center side corners of the cutouts 32a and 32b ( Two cutout portions 32a and 32b are formed with a distance dimension located between the cutting edge portions 33a and 33b and the cutting blade outer corner portions 34 and 34, and the tape 10 is straightened from the tape roll 1. When pulled out and placed on the cutting blade 31, the notches 32 a and 32 b of the cutting blade 31 come into contact with the left and right side edges 10 a and 10 b of the tape 10.

  In order to cut the tape 10, as shown in FIG. 9, the tape 10 is pulled out (rewinded) from the tape roll 1 to lower the tape 10 downward, and a force is applied to either the left or right edge 10 a or 10 b of the tape 10. What is necessary is just to press on the cutting blade 31 (notch part 32a or 32b). Then, the inner corner part (cutting part) 33a or 33b of the cutout part 32a or 32b tears the edge part 10a or 10b of the tape 10, and the tape 10 is straightened (in a straight line) along the straight cutting edge of the cutting blade 31. ) Disconnected. Although the number of the notches 32a and 32b may be one as shown in FIG. 12, in the present embodiment, the notches (notches) 32a and 32b are provided on the left and right of the cutting blade 31, and therefore the tape 10 The tape 10 can be cut from either the left or right edge 10a, 10b.

  In the present embodiment, the cutout portions 32a and 32b are formed in a dominant arc (an arc larger than a semicircle) as further enlarged in FIG. As a result, the cut ends 33a and 33b are sharpened with an acute angle smaller than a right angle, so that the edges 10a and 10b of the tape 10 can be easily cut with a smaller force. The diameter of the arcs of the notches 32a and 32b depends on the type (material, thickness, etc.) of the tape 10, but in the case of a resin adhesive tape for office use, it can be about 1 mm to 1.5 mm, for example. In the case of this embodiment, the cutting blade 31 is integrally formed with resin together with the tape locking portion 22, the arm portion 20b, and the tape roll holding portion 12b (the other side plate 15b of the dispenser).
