Description

  The present invention relates to a tape cutter used when cutting a cellophane tape.

  In general, when using a cellophane tape, the end of the tape is pulled and cut into an arbitrary length. The tape can be cut by hand, using scissors or a cutter, or by attaching cellophane tape to a tape holder with a cutter, pinching the end of the tape with your finger, and pulling out the tape as much as necessary. There is also a method of cutting with a cutter.

  Since an adhesive is applied to one or both sides of the adhesive tape, if the finger is pinched with a finger, the fingerprint of the finger may adhere to the adhesive surface. When a fingerprint adheres to the adhesive surface, the adhesive strength is reduced due to the oil and fat component contained in the fingerprint, and the appearance becomes unclean and lacks aesthetics. Then, the technique regarding the tape cutter which prevents a fingerprint adhering to an adhesive surface by forming a knob in the edge part of an adhesive tape is disclosed (for example, patent document 1).

  Patent Document 1 is a tape cutter including a movable cutter portion 32 having a cutting blade 321 and a temporary receiving portion 322 formed at the tip, and when the adhesive tape drawn out to a desired length is cut with the cutting blade 321, The adhesive tape end on the tape roller body side adheres to the temporary receiving portion 322, and the movable cutter portion 32 is pushed back to the tape holder rising portion side by a spring force, so that a loop-shaped one is formed at the tip of the adhesive tape. This technology is disclosed. When the user next time uses the loop-shaped object, a tab (peeling tab) is formed at the tip of the tape. By grabbing this knob and pulling out the adhesive tape and cutting it, the tape adhesive surface It is supposed that fingerprints can be prevented from adhering to the surface.

JP 2004-284687 A

  According to the technique disclosed in Patent Document 1, a knob is still formed at one end of the cut tape. Therefore, even when it is possible to prevent the fingerprint from adhering to the tape when it is adhered to the object, the knob remains even after the tape is adhered. There are problems such as the knob getting in the way and the tape coming off. In order to avoid this problem, it is possible to remove the knob, but using scissors or a tape cutter may damage the object, and it is troublesome to prepare a new scissor or tape cutter to remove the knob. Take it.

  In addition, there are various uses of the adhesive tape, and when using it without worrying about fingerprints, there are cases where it is desirable to leave a knob, but according to the technique disclosed in Patent Document 1, Since a knob is always formed, it cannot cope with various uses.

  Therefore, the present invention provides a case where it is desired to use a tape without forming a knob, when a knob is formed and then used without removing the knob after being applied, or when a knob is formed and desired to be removed after being applied. It aims at disclosing the tape cutter which can respond to any use.

The prototype of the tape cutter which is one embodiment of the present invention is photographed obliquely from above. The tape cutter shown in FIG. 11 is taken from another direction.

  FIG. 1 is an explanatory diagram of the internal structure of a tape cutter according to an embodiment of the present invention. A tape cutter 1 according to an embodiment of the present invention is used by being placed on a desk. The tape cutter 1 has a rectangular bottom plate 10 placed on a desk, and two side plates 11 and 20 fixed so as to sandwich the bottom plate 10. The bottom plate 10 and the side plates 11 and 20 form a storage space in which the cellophane tape body 30, the U-shaped link 40 as the first link, the G-shaped link 60 as the second link, and the like are incorporated. . Hereinafter, for convenience of explanation, the side on which the cellophane tape main body 30 is disposed may be referred to as “rear side”, and the side on which the blade for cutting the cellophane tape drawn from the cellophane tape main body 30 is disposed may be referred to as “front side”. .

  FIG. 2 is a front view of a fixing box side plate according to an embodiment of the present invention. The side plate 11 has an insertion hole 12 into which a shaft 31 (see FIG. 1) for supporting the U-shaped link 40 is swingably inserted, and a shaft 32 for supporting the U-shaped link 60 so as to be swingable. An insertion hole 14 into which (see FIG. 1) is inserted and fixed is formed.

  Further, a switching groove 13 is formed at the lower center of the side plate 11. This switching groove 13 is formed in three horizontal stages extending vertically, and is composed of a knob / perforation creating groove 13a, a knob creating groove 13b, and a cut only groove 13c in order from the top. Each of the knob / perforation creating groove 13a, the knob creating groove 13b, and the cut only groove 13c is formed in the horizontal direction, and the vertical groove 13d communicating with each of the grooves 13a, 13b, and 13c is formed in the vertical direction. Has been. Note that the side plate 20 also has insertion holes and switching grooves (not shown) similar to those formed on the side plate 11 at the same position.

  As shown in FIG. 1, a switching shaft 33 is inserted in the switching groove 13, and any of the knob / perforation creating groove 13a, the knob creating groove 13b, and the cut only groove 13c is used. It ’s free to move.

  FIG. 3 is a front view of a U-shaped link according to an embodiment of the present invention, and FIG. 4 is a top view thereof. The U-shaped link 40 as the first link includes a pair of U-shaped main body portions 41 and 50 arranged so as to sandwich the cellophane tape main body 30, and these U-shaped main body portions 41. , 50 are formed integrally with the tape bonding portion 42 arranged in the width direction of the tape.

  The U-shaped main body 41 includes a blade body support groove 41 having a blade body operating groove 43 at the tip and a bearing hole 44 formed at a substantially central portion in the longitudinal direction, and a tape that rotatably supports the cellophane tape body 30. The mounting portion 41b is configured by a connecting portion 41c that connects the blade support portion 41a and the tape mounting portion 41b and contacts the switching shaft 33 when the tape is cut. Since the other U-shaped main body portion 50 that forms a pair with the U-shaped main body portion 41 has the same configuration, the description of the U-shaped main body portion 50 is omitted.

  These U-shaped main body portions 41 and 50 are arranged in parallel on both sides of the cellophane tape main body 30. The tape bonding part 42 is provided with a slit 45 into which a perforation creating blade (not shown) is incorporated, and the perforation creating blade (not shown) can protrude upward from the slit 45. ing. Both sides of the slit 45 are cellophane tape bonding surfaces 46a and 46b.

  In the present embodiment, the cut amount adjusting member 47 is joined to the cellophane tape bonding surface 46 a far from the cellophane tape body 30. The cut amount adjusting member 47 prevents the perforation forming blade 36 protruding from the slit 45 from coming into contact with the tape when only the knob is to be formed at the tip of the tape (that is, when it is not desired to create the perforation). The height of the cellophane tape bonding surface 46a is adjusted (see FIG. 1). When the cut amount adjusting member 47 is joined, the upper surface (top surface) of the cut amount adjusting member 47 functions as the tape bonding surface 46a.

  A shaft 34 that is inserted into and fixed to the insertion hole 12 formed in the side plate 11 is slidably inserted into the bearing hole 44. An insertion hole (not shown) is also formed in the side plate 20 arranged in parallel to the side plate 11 at a position facing the insertion hole 12. That is, the U-shaped link 40 can swing with respect to the side plates 11 and 20 with the shaft 34 as a fulcrum. Therefore, when the end of the cellophane tape is grasped and the tip is pulled forward, the cellophane tape main body 30 is lifted upward by the tension at that time, and the U-shaped link 40 is lifted upward with the shaft 34 as a fulcrum. .

  Here, when the switching shaft 33 is inserted into the switching groove 13, the range in which the U-shaped link 40 is lifted is limited by the connection portion 41 c coming into contact with the switching shaft 33. That is, when the switching shaft 33 is inserted into the knob / perforation creating groove 13a, the connection shaft 41c is brought into contact with the switching shaft 33 in the knob / perforation creating groove 13a. The character-shaped link 40 will be lifted. As described above, the knob / perforation creating groove 13a is formed above the other grooves 13b, 13c, so that the switch shaft 33 is inserted into the other grooves 13b, 13c. The U-shaped link 40 is lifted larger and tilted forward.

  On the other hand, when the switching shaft 33 is inserted in the knob creating groove 13b, the U-shaped link 40 is lifted up to a position where the connecting portion 41c contacts the switching shaft 33 in the knob creating groove 13b. However, as described above, since the knob creating groove 13b is formed below the knob / perforated line creating groove 13a, the switching shaft 33 is inserted into the knob / perforated line creating groove 13a. Compared to the case, the inclination becomes smaller.

  When the switching shaft 33 is inserted into the cut-only groove 13c, the U-shaped link is lifted to a position where the connecting portion 41c comes into contact with the switching shaft 33 in the cut-only groove 13c. . As described above, since the cut-only groove 13c is formed below the other grooves 13a and 13b, the inclination of the U-shaped link 40 is the smallest. In the present embodiment, the cut-only groove 13c is formed in the horizontal direction at substantially the same height as the height position of the upper surface of the connecting portion 41c. The inclination of the character-shaped link 40 is restricted to a substantially horizontal position, and is not inclined substantially to the front side.

  As shown in FIG. 1, a blade body mounting base 35 is attached to the blade body operating groove 43 at the tip of the U-shaped link 40 so as to be movable up and down (slidable). A perforation creating blade 36 is mounted on the upper surface of the blade mounting base 35 with the blade facing upward. When the blade mounting base 35 moves to the upper end side of the blade operating groove 43, a perforation is created. The blade 36 is assembled so as to emerge from the slit 45 of the tape bonding portion 42. The perforation creating blade 36 has a chevron saw blade shape, and can create a perforated cut on the cellophane tape. Further, the perforation creating blade 36 is detachable and can be replaced with an optimum blade according to the material and thickness of the tape.

  The G-shaped link 60 as the second link includes a short side portion 60a and a long side portion 60b. The short side portion 60 a is connected to one end of the blade attachment link 63. The other end of the blade attachment link 63 is connected to the blade attachment base 35. As described above, the blade body mounting base 35 is mounted so as to be movable up and down along the blade body operating groove 43. Accordingly, the blade body mounting base 35 is moved up and down in conjunction with the movement of the G-shaped link 60. Will move.

  A tape cutting blade 37 is mounted on the upper end side of the long side portion 60b, and one end of the connection link 65 is swingably connected to the lower end side. The other end of the connection link 65 is swingably connected to the lower end side of the blade support part 41a of the U-shaped link 40.

  A bearing hole 61 into which a shaft 32 for swingably supporting the U-shaped link 60 is inserted is formed slightly above the joint portion with the connection link 65 of the long side portion 60b. That is, the G-shaped link 60 can swing with respect to the side plates 11 and 20 with the shaft 32 as a fulcrum.

  Next, the movement of the U-shaped link 60 will be described with reference to FIGS. FIGS. 5 to 7 are explanatory views of the operation state of the tape cutter according to the embodiment of the present invention. In particular, FIG. 5 shows the operation state when forming the knob and the perforation, and FIG. 6 shows the knob. FIG. 7 shows an operating state when neither a knob nor a perforation is formed.

  First, in a normal state in which the cellophane tape is not pulled out, the long side portion 60b of the U-shaped link 60 is substantially in a vertical position. And the upper end side of the long side part 60b with which the tape cutting blade 37 was mounted | worn is contacting the blade body support part 41a of the U-shaped link 40. As shown in FIG.

  Next, when the cellophane tape is pulled out, the cellophane tape main body 30 is pulled upward, the U-shaped link 40 tilts forward with the shaft 34 as a fulcrum, and in conjunction with the movement of the connection link 65 and the blade attachment link 63. The G-shaped link 60 tilts forward with the shaft 32 as a fulcrum. The inclination at this time varies depending on the position of the switching shaft 33. That is, when the switching shaft 33 is inserted into the knob / perforation creating groove 13a, the U-shaped link 40 is lifted more greatly and tilted forward greatly. In conjunction with this, the U-shaped link 60 is also largely inclined forward (see FIG. 5). At this time, the long side portion 60b of the G-shaped link 60 is separated from the blade body support portion 41a and protrudes to the outside of the side plates 11 and 12 in the present embodiment.

  When the switching shaft 33 is inserted into the knob creating groove 13b, the U-shaped link 40 is inclined as compared with the case where the switching shaft 33 is inserted into the knob / perforation creating groove 13a. Therefore, the G-shaped link 60 is also slightly inclined forward (see FIG. 6). In addition, when the switching shaft 33 is inserted only into the cut groove 13c, the inclination of the U-shaped link 40 is regulated to a substantially horizontal position and does not substantially tilt to the front side. The link 60 is also not substantially inclined forward (see FIG. 7).

  Next, when the drawn cellophane tape is cut by the tape cutting blade 37, the tension that lifted the cellophane tape main body 30 upward is lost, so the cellophane tape main body 30 moves downward and returns to the state shown in FIG. In conjunction with the movement, the long side portion 60b of the U-shaped link 60 returns to a substantially vertical position, and the long side portion 60b of the G-shaped link 60 is again the blade body support portion of the U-shaped link 40. 41a is contacted.

  Here, the tape cutting blade 37 will be described. The tape cut blade 37 has a flat portion 37a and a blade edge portion 37b. The tape cut blade 37 is mounted with the blade edge portion 37b facing the front lower side. The cutting of the cellophane tape is performed at the blade edge portion 37b. Since the blade edge portion 37b is attached to the front lower side, the cellophane tape is cut when the drawn cellophane tape is lowered toward the blade edge portion 37b and cut. The tip of the cellophane tape on the main body 30 side is bonded to the flat portion 37a. That is, the tip of the cellophane tape after cutting is in a state of being bonded to the flat portion 37a.

  The operation of the tape cutter having the above configuration will be described below.

  First, a case where a knob is formed at the tip of the cellophane tape after cutting and it is desired to remove the knob after being attached to an object will be described with reference to FIGS. 1 and 5.

  First, before pulling out the cellophane tape from the cellophane tape main body 30, the position of the switching shaft 33 is moved to the knob / perforation creating groove 13a. Then, the cellophane tape is pulled out diagonally forward. Then, due to the pulling force (tension), the U-shaped link 40 and the G-shaped link 60 are largely inclined to the front side as described above, and the long side portion 60b of the G-shaped link 60 supports the blade body. It is far from the portion 41a. At this time, in conjunction with the movement of the U-shaped link 40 and the U-shaped link 60, the blade body mounting base 35 moves upward, and the perforation creating blade 36 of the blade body mounting base 35 protrudes from the slit 45. Appear. After the cellophane tape is pulled out by a desired length toward the front upper side, the cellophane tape is lowered in the direction of the tape cutting blade 37. Then, the cellophane tape is cut to a desired length in a state where the tip of the cellophane tape on the cellophane tape main body 30 side adheres to the flat portion 37a and the abdomen of the cellophane tape adheres to the cellophane tape adhering surfaces 46a, 46b. At this time, since the raised perforation creating blade 36 is stuck in the middle part of the cellophane tape, a perforated notch is formed.

  When the cellophane tape is cut, the tension disappears and the cellophane tape main body returns to its original position, and the long side portion 60b of the U-shaped link 60 is the blade body support portion of the U-shaped link 40. It returns to the position which contacts 41a. At this time, the tip of the cellophane tape is bonded to the flat portion 37a, and the abdomen of the cellophane tape is bonded to the cellophane tape bonding surface 46b and the cellophane tape bonding surface 46a on the upper surface of the cut amount adjusting member 47, Since the long side portion 60b of the link 60 moves to a position where it contacts the blade body support portion 41a of the U-shaped link 40, a cellophane tape loop is formed between the cut amount adjusting member 47 and the flat portion 37a. 30a is formed. The next time the cellophane tape is pulled out and cut, the inner surface of the loop 30a is bonded to each other by pinching and pulling out the loop 30a, thereby forming a knob portion. A perforated notch is formed near the base of the knob. A cellophane tape with a loop-shaped knob at the tip and a perforation 30c behind it is left on the tape cutter.

  FIG. 8 is a schematic diagram of the knob and the perforated tape created in the operating state shown in FIG. 5, and FIG. 9 shows a state in which the adhesive surface is stuck to the object to be pasted with the knob pinched with the fingertip 10 shows how to remove the knob by tearing it along the perforation. A cellophane tape with knobs and perforations can be made by pinching the knobs and repeating the above-described operation. After the tape is adhered to a predetermined place, the knob 30b is moved along the perforations 30c. Thus, the knob 30b can be easily removed by tearing.

  According to the present invention, when a knob is formed and it is desired to remove the knob 30b after sticking, the knob 30b is removed by tearing the knob 30b along a perforated notch that is automatically formed when the tape is cut. Therefore, it is not necessary to separately prepare scissors and a tape cutter, and the knob 30b can be removed along the perforation 30c, so that the object is not damaged.

  Second, the operation when only the knob is created and the cellophane tape is cut will be described with reference to FIG. By aligning the switching shaft 33 with the middle stage of the switching groove 13 and the groove for making the knob, the U-shaped link 40 and the U-shaped link 60 are inclined forward when the cellophane tape is pulled out to the upper front. However, unlike the knob and perforation creation, the blade mounting base 35 is inclined so as not to rise. Therefore, the perforation creating blade 36 of the blade mounting base 35 does not protrude from the slit 45. In this state, the cellophane tape is pulled out by a desired length toward the front upper side, and then the cellophane tape is lowered toward the tape cutting blade 37. Then, with the cellophane tape tip attached to the cellophane tape main body 30 side adhered to the flat portion 37a of the tape cutting blade 37, the cellophane tape middle portion adhered to the cellophane tape adhering surface 46b and the cut amount adjusting member 47, Although it cut | disconnects by desired length, since the perforation preparation blade 36 does not pierce in the middle part of a cellophane tape, a perforation-like notch is not formed. In the case shown in the figure, the cut amount adjusting member 47 is provided, so that contact with the perforation creating blade 36 is reliably avoided.

  When the cellophane tape is cut, the tension is lost and the cellophane tape main body 30 returns to its original position, and the long side portion 60b of the U-shaped link 60 supports the blade body of the U-shaped link 40. It returns to the position which contacts the part 41a. At this time, the tip of the cellophane tape is bonded to the flat portion 37a and the middle portion of the cellophane tape is bonded to the cellophane tape bonding surface 46b and the cut amount adjusting member 47, and the long side portion 60b of the toroidal link 60 is left. Moves to a position where it contacts the blade body support portion 41a of the U-shaped link 40, so that a cellophane tape loop (see FIG. 1) is formed between the cut amount adjusting member 47 and the flat portion 37a. Is done. Next time, when the cellophane tape is pulled out and cut, the knob is formed by pinching the loop and adhering the inner surfaces of the loops to each other.

  In this state, the next time it is used, the cellophane tape with the knob can be prepared by pinching the loop, pulling out the cellophane tape and cutting it. Thereby, it can respond to the case where it is desired to use the knob without removing the knob after sticking after forming the knob.

  Third, the operation when neither perforation nor knob is created will be described with reference to FIG. In this case, by aligning the switching shaft 33 with only the cut groove 13c at the lowermost stage of the switching groove 13, the inclination of the U-shaped link 40 is regulated to a substantially horizontal position and is not inclined to the front side. The G-shaped link 60 is also not substantially inclined to the front side. Therefore, the long side portion 60b of the toroidal link 60 remains in contact with the blade body support portion 41a.

  In this state, the cellophane tape is only cut by the tape cutting blade 37. The cellophane tape after cutting adheres to the flat portion 37a, the cellophane tape adhesive surface 46b, and the cutting amount adjusting member 47, and waits for the next tape drawing. Thereby, when it is desired to use a tape without forming a knob, it is possible to cope with a case where it is desired to use the tape without creating a knob or a perforation.

  In the embodiment described above, the cut amount adjusting member 47 is provided. However, the cut amount adjusting member is adjusted by adjusting design items such as the mounting height of the tape cutting blade 37 and the perforated blade 36. 47 can be eliminated.

  11 and 12 are photographs of a prototype of a tape cutter according to an embodiment of the present invention, obliquely from above. The feasibility of the present invention and the effects of the invention have been demonstrated.
