Description

Box Tape Cutter {Cutter for Box-tape}

The present invention relates to a box tape cutter for attaching a tape film to a box and for cutting the tape film.

In general, a box is used to package an article. The box is used by folding the cardboard into a hexahedral shape, and attaching tape to prevent the cardboard from unfolding.

The tape has a film wound on a tape wick, an adhesive layer is formed on the film, and even though the tape manufacturers are different, the tape standard is unified and sold.

On the other hand, logistics increase according to the interests of consumers, sellers, and manufacturers, and accordingly, the amount of box packaging work for packaging and transporting goods is increasing.

In the box packaging operation, the tape is mounted on the tape cutter, the adhesive layer of the film is adhered to the surface of the box, and the tape cutter is moved to unwind the film.

On the other hand, the tape cutter has a blade in the form of a sawtooth disposed at the front end, and when the user pulls the tape cutter by applying force while tilting it in the direction in which the tape cutter is erected, the film can be cut with the blade.

Immediately after the film of the tape is cut, a part of the film remains stuck or slightly attached to the blade, thereby adhering the adhesive layer to the box during the next packaging operation, and the film often falls from the blade.

In addition, as described above, the tape has an adhesive layer formed on the film, and if the film is left unwrapped from the tape wick, it tends to bend toward the adhesive layer even when no external force is applied. there is a ham

On the other hand, the conventionally known tape cutter is provided with a guide structure to prevent the film of the tape from being folded regardless of the user's intention or to be easily unfolded even if folded, as described above. The guide structure may be in the form of a roller, and is provided in a form fixed to the body of the tape cutter.

When replacing or installing a new tape on the tape cutter, unwind the film of the tape to a length of several centimeters, mount the tape on the shaft of the tape cutter, pass the film between the press roller and the guide element, and end the film Attaches to the blade and cuts to complete the tape installation.

However, the conventionally known tape cutter as described above has the following problems.

In the tape cutter, the gap between the press roller and the guide structure is as narrow as 1 cm or less, and since an adhesive layer is formed on one side of the film, it is inconvenient to insert the film through a narrow gap. It is very inconvenient to attach the tape to the tape cutter because it sticks.

On the other hand, the film is unwound by moving the tape cutter, and the film is attached to the surface of the box immediately after unwinding, in which the tape wick can freely move in the axial direction on the shaft of the tape cutter and, more specifically, approximately several millimeters wide. Since it can move freely within the range, there is a problem that the film cannot be unwound in a straight line and can be distorted when unwinding.

Even if the film of the tape is attached slightly crookedly, it is not functionally a problem for packaging the box, but it is not good aesthetically and needs to be improved.

Also, it is possible to form guides on both surfaces of the shaft to align the tape wick to a specific position on the shaft, but in this case, the rotation of the tape wick is not free, which may prevent the film from being unwound, and the rotation of the tape wick may be prevented. There is a possibility that the film may break as it interferes with the film.

On the other hand, conventionally, the blade is provided in a serrated shape, but the height of the mountain is constant, and when the film contacts the serrated mountain of the blade, several contact points are in common contact, and in this case, the pressure applied by the user is The film was not cut well because it was dispersed to the contact point, and it was inconvenient.

In addition, in the prior art, a technique for arranging the blade in an oblique posture relative to the direction in which the body moves is known, and the film is made to face at one point of the blade so that the film is torn at that point, but to expect this action For this, users must pay attention. For example, the user has to remember at which point the film and the blade come into contact, and there is an inconvenience in that special attention must be paid to apply pressure to the contact point.

In addition, in the prior art, there is an inconvenience in that the user has to abnormally excessively bend the wrist or apply excessive force to cut the film.
