Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape cutter for pulling out and cutting an adhesive tape wound in an annular shape.

[0002]

2. Description of the Related Art An example of this type of tape cutting device is shown in FIG. In the figure, the annular body 4
In No. 1, an adhesive tape 42 is wound around a cylindrical core 43, and a tape cutting device 44 is attached to this annular body 41.

The tape cutter 44 is formed by bending a punched metal plate, bending a pair of side plates 47 on both sides of the main plate 46 at a right angle, and bending a pair of claws 48 at the ends of these side plates 47 at a right angle. The hooks 48 are hooked on the inner circumference of the annular body 41. As a result, the tape cutting device 44 is movably supported on the outer circumference of the annular body 41. A saw blade 49 is formed on one side of the main plate 46.

Here, as shown in FIG. 5 (a), while rotating the tape cutting device 44 in the direction of arrow A, the adhesive tape 42 is pulled out from the annular body 41 in the direction of arrow B, after which FIG.
As shown in (b), when the adhesive tape 42 is pulled in the direction of arrow C, the adhesive tape 42 is pressed against the saw blade 49 of the tape cutting device 44 and cut.

[0005]

However, when the conventional tape cutter is used, the end of the adhesive tape 42 adheres to the outer peripheral surface of the annular body 41 every time the adhesive tape 42 is cut. When pulling out the adhesive tape 42, the end of the adhesive tape 42 has to be peeled off, and the work therefor is very troublesome and takes time.

Further, the saw blade 49 causes the adhesive tape 42
Since the adhesive tape 42 has a saw-toothed edge because it is cut, the sawtoothed edge is easily torn, which makes the work of peeling off the edge of the adhesive tape 42 more difficult.

In this type of tape cutting machine,
There is one in which the end of the adhesive tape is separated from the outer peripheral surface of the annular body 41, which makes it easy to pull out the end of the adhesive tape, but it is relatively large and is installed on a desk. , Not available anywhere at any time.

SUMMARY OF THE INVENTION An object of the present invention is to provide a simple tape cutting device which facilitates pulling out the end of an adhesive tape and can be used anytime and anywhere.

[0009]

In order to solve the above-mentioned problems, a tape cutter according to claim 1 has a width substantially the same as that of a tape, and a hole through which the tape is inserted is formed. A tape lead-out portion, a blade protruding from the tape lead-out portion, and a support means for movably supporting the tape lead-out portion on the outer circumference of an annular body formed by winding the tape.

The tape cutting device according to the second aspect of the invention has a tape lead-out plate having a width substantially the same as that of the tape and having a hole for passing the tape, and extending from the tape lead-out plate. , A pair of side plates extending from both sides of the blade and the tape lead-out plate that are bent at a substantially right angle and bent at a right angle in the opposite direction to the blade, and extended from each side plate and substantially parallel to the tape lead-out plate And a pair of claws that can be bent until they are formed.

[0011]

In the tape cutting device of the first aspect, the tape guiding portion is movably supported on the outer circumference of the annular body by the supporting means. Holding the tape cutting device in hand, the tape of the annular body is pulled out through the hole of the tape lead-out portion. Along with this, the annular body rotates, so that the tape can be pulled out quickly. The tape is cut by pressing a blade protruding from the tape lead-out portion against the tape. At this time, since the end of the tape is still pulled out from the hole of the tape lead-out portion, the end of the tape does not have to adhere to the outer peripheral surface of the annular body. Therefore, when pulling out the end of the tape again, the work can be performed quickly.

Further, in the tape cutting device of the second aspect, the tape lead-out plate, the blades extended from the tape lead-out plate, the side plates extended from both sides of the tape lead-out plate, and the side plates extended from these side plates. The tape cutting device can be formed by punching and bending a single metal plate because it is composed of each claw. Here, the tape lead-out plate is arranged on the outer periphery of the annular body, and the pair of side plates on both sides of the tape lead-out plate are bent,
By further bending the claws of these side plates and hooking these claws on the inner circumference of the annular body, the tape cutting device is movably supported by the annular body. Holding the tape cutting device in hand, while rotating the annular body, the tape of the annular body is pulled out through the hole of the tape lead-out plate. When the blade raised from the tape lead-out plate is pressed against this tape, this tape is cut. Even when the tape is cut, the end of the tape is still pulled out from the hole of the tape lead-out plate, so that the end of the tape does not adhere to the outer peripheral surface of the annular body.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is an expanded view of an embodiment of the tape cutter of the present invention. Tape cutter 1 of this embodiment
Is formed by stamping a metal plate of galvanized iron or tin plate with a die. At the time of punching, the tape cutting device 1 is provided with each groove 2 for facilitating bending and each unevenness 3 for improving rigidity. These irregularities 3 are recessed on one surface of the metal plate and project on the other surface.

The tape cutting device 1 includes a tape lead-out plate 4
And the saw blade 5 and the sliding edge 6 inside the tape lead-out plate 4.
And side plates 7 on both sides of the tape lead-out plate 4 and claws 8 extended from these side plates 7.

In order to attach the tape cutter 1 to the annular body 11 as shown in FIG. 2, first the saw blade 5 and the sliding edge 6 are attached.
Is bent at each groove 2, the saw blade 5 is raised at a substantially right angle, and the sliding edge 6 is folded back. After this, the tape lead-out plate 4 is pressed against the outer circumference of the annular body 11 and each side plate 7 is pressed.
Is bent at a right angle in each of the groove grooves 2, each claw 8 is further bent at a right angle, and these claws 8 are hooked on the inner circumference of the annular body 11. As a result, the tape cutting device 1 becomes the annular body 1.
It is movably supported on the outer periphery of 1.

Here, the tape cutting device 1 is bent so that the surface on which the projections and depressions 3 project is inward. For this reason, the roundness of each concavo-convex 3 contacts the annular body 11, but the tape cutter 1 moves smoothly.

Since the saw blade 5 and the sliding edge 6 are raised, a hole 4a is formed in the tape lead-out plate 4. The adhesive tape 12 of the annular body 11 is pulled out through the hole 4a.

Now, with the tape cutting device 1 in hand,
As shown in FIG. 3A, the adhesive tape 12 is pulled out in the direction of arrow P. Along with this, the annular body 11 rotates in the direction of arrow Q. At this time, the adhesive tape 12 comes into contact with the smooth surface of the sliding edge 6 that has been folded back, so that the adhesive tape 12 is not damaged. Subsequently, FIG.
As shown in (b), the saw blade 5 is pressed against the adhesive tape 12 to cut the adhesive tape 12.

When the adhesive tape 12 is cut, the end of the adhesive tape 12 adheres to the saw blade 5 as shown in FIG. 2, so that the end of the adhesive tape 12 does not have to adhere to the outer peripheral surface of the annular body 11.

Holding the tape cutter 1 in this way,
The pressure-sensitive adhesive tape 12 can be pulled out while rotating the annular body 11, and when the pressure-sensitive adhesive tape 12 is cut, the end of the pressure-sensitive adhesive tape 12 does not have to adhere to the outer peripheral surface of the ring-shaped body 11. The operation of pulling out and cutting the tape 12 can be repeated rapidly.

Since the tape cutting device 1 does not become bulky if it is developed in a flat plate shape as shown in FIG. 1, the flat plate tape cutting device 1 is stacked on the annular body 11 and packaged. You can sell it. In this case, the user bends the flat-plate tape cutting device 1 and attaches the tape cutting device 1 to the annular body 11.

Further, the tape cutting device shown here is only one embodiment and may be modified appropriately. For example, the saw blade 5 of the tape cutting device 1 shown in FIG. 1 is deleted, a hole is made there, and instead of this saw blade 5, the tape lead-out plate 4 is used.
It is also possible to form a saw blade extending from one side 4b and raise the saw blade at a right angle.

Further, the tape cutting device of the present invention is not limited to a punched metal plate, but may be composed of several parts. In short, it suffices to movably support the tape lead-out plate on the outer periphery of the annular body, form a hole for passing the tape through the tape lead-out plate, and project a blade on the tape lead-out plate.

[0025]

[Effect] As described above, since the annular tape is pulled out through the hole of the tape lead-out portion, the end of the tape does not adhere to the outer peripheral surface of the annular body even when the tape is cut. The work of pulling out and cutting the tape can be repeated promptly.
