Abstract

Provided is a tape cutter for automatically forming a peeling tab on a tape end in order to easily peel off a tacked adhesive tape.
SOLUTION: A roller 4 that can be slid up and down on a fixed base 3 at a tape end of an adhesive tape cutter, and a movable cutting tooth 5 that is slidably installed at an open end and a close end are provided on a cutter body 1. The roller 4 and the drive lever of the cutting teeth 5 are connected to each other by a connecting rod 7 so that the roller 4 is pushed up by the tension generated on the tape when the tape is pulled out from the tape reel. The interlocking cutting teeth 5 also automatically move to the open end, and when the tape tension is lost by cutting the tape with the cutting teeth 5, the cutting teeth 5 are brought about by the gravity of the roller 4 and the spring provided inside. Automatically moves to the closing end, and at the same time, the end of the tape adhering to the tip of the cutting tooth 5 is also pulled back to the closing end to form a loop 9.

Description

  The present invention relates to an adhesive tape cutter for forming a peeling tab for facilitating peeling of a temporarily attached adhesive tape.

For packaging foods sold at supermarkets, convenience stores, side dishes, confectionery, etc., plastic packs fixed with adhesive tape are often used.
This adhesive tape must be peeled off when unpacked, but it is difficult to find the end of the tape due to its transparency, etc. Many.
Conventionally, the following two methods have been devised as means for solving this problem.
a. A separate sheet (peeling tag) is attached to the adhesive surface at the end of the tape to create a non-attached part.
b. Fold the end of the tape to make a non-stick part.
However, in the method a, it is necessary to prepare a separate paper for the peeling tag, which is troublesome and inevitably increases the cost.
Examples of the invention or device according to the method b include the following, but operations such as turning the handle to make the folded portion are required, skill of the fingertip is required for the operation, two-handed operation is required, motors, etc. Each of them has other problems, such as the need for another power source, and it has not been widely used.

  Therefore, the present invention of claim 1 adds a mechanism for automatically making a loop back to the end of the tape using the operation of pulling and cutting the tape to the tabletop tape cutter, and requires special operation and skill. In addition, the present invention provides an adhesive tape cutter that can be used in the same manner as a general tape cutter without requiring any other power and can easily produce a tape with a peeling tab.

An end of the cutter body 1 is provided with a roller 4 that can be swung up and down on a fixed base 3 at a tape end of a tabletop adhesive tape cutter, and a movable cutting tooth 5 that is slidably movable to an open end and a close end. The roller 4 and the drive lever of the cutting teeth 5 are connected by a connecting rod 7, so that when the roller 4 is pushed up by the tension generated in the tape when the tape is pulled out from the tape reel, the connecting rod 7 interlocks. The cutting teeth 5 to be moved automatically move to the open end, and when the tape tension is lost by cutting the tape with the cutting teeth 5, the cutting teeth 5 are moved by the gravity of the roller 4 and the spring provided inside. It automatically moves to the closed end, and at the same time, the end of the tape adhering to the tip of the cutting tooth 5 is also pulled back toward the closed end to form a loop 9.
By picking the loop part with a finger and pulling out and cutting the tape, a tape having a peeling tab at the end part is obtained. By repeating this operation, a tape with a peeling tab can be continuously produced.

  It is an inexpensive and portable device that can be used to easily create and use a tape with a peeling tab not only in large stores such as supermarkets, but also in small stores and general households.

To manufacture the tape cutter of the present invention, the mechanism itself is simple and does not require any special technique, but the design should pay attention to the following points in order to ensure stable loop formation, ease of operation and safety There is a need.
1. Since the tape tension generated when the tape is pulled out is used, the tape cutter needs to be able to withstand the weight (about 800 gr. Or more).
Therefore, the main body is preferably made of metal (cast iron or alloy casting) rather than resin, and it is also preferable for ensuring the durability of movable parts such as rollers and cutting teeth.
2. In order to stably form the loop, the tape is prevented from being folded backward (adhesive surface outward) when the tape is pulled back, and the entire tape is moved backward when the cutting teeth 5 are moved to the closed end. You must prevent it.
Therefore, the cross-sectional shape of the tape fixing base 3 in contact with the roller is as shown in FIG. 3, and when the roller pushes down the tape, the end of the tape is kicked upward by the difference in height of the fixing base (Δh), And a structure in which a tape is attached to the fixed base 3 to prevent back-turning.
In addition, it is desirable that the width of the contact surface between the fixing base 3 and the roller is as narrow as possible so that excessive adhesive does not adhere even after repeated use.
3. At the initial stage of tape withdrawal, the movable cutting tooth 5 and the finger are close to each other, and there is a risk of touching the cutting tooth 5 and damaging the finger. Further, since the movement of the cutting teeth 5 may be faster than expected by the operator as it gets used, the following considerations are necessary in terms of design.
a. The moving direction of the cutting teeth should be as downward as possible (the direction away from the finger).
b. The connecting hole 8 of the connecting rod 7 connected to the cutting tooth 5 has a play as a long hole, and the connecting rod 7 does not act as much as the play at the beginning of the tape drawing, and it is connected only after the roller reaches the appropriate height. A structure is adopted in which the bar 7 acts and the cutting teeth 5 begin to move. In other words, the cutting tooth 5 starts to move after the finger is sufficiently separated from the cutting tooth 5.

FIG. 5 shows an example of a mechanism for fixing the movable cutting tooth 5 of claim 2 to the open end and using it as a normal tape cutter that does not form a peeling tab.
By moving the eccentric cam 10 to the fixed side and the release side with the knob, the movable and fixed cutting teeth 5 are selected. A locking mechanism such as a stopper can be used without depending on the eccentric cam.

FIG. 6 shows an example of a mechanism for allowing the length (L) of the peeling tab to be freely selected.
Since the length of the peeling tab is proportional to the stroke of the movable cutting tooth 5, an example of a mechanism that makes the position of the open end stopper 11 variable by turning the screw knob 12 is shown.
Usually, it is considered sufficient that the length of the peeling tab can be selected from several types such as long, medium, and short. Therefore, it is possible to adopt a simple mechanism such as inserting and removing a spacer without using a screw.

  It can be used as a business or general household tape cutter.
