Description

TAPE DISPENSOR

The present invention relates to an adhesive tape cutting device, and more specifically, it is stably mounted between the tape roll and the cutting device without becoming loose, can guarantee the user's safety to prevent injuries caused by the cutter, and reduces production costs. It relates to an adhesive tape cutting device that can be easily peeled off when using an adhesive tape, ensuring the convenience of quick use, and easily attachable to and detachable from a tape roll.

Generally, adhesive tape is made by wrapping dozens or hundreds of layers of adhesive on one side of a cellophane or vinyl film on the outside of a paper tube, roll, etc. It is used for efficient cleaning, reinforcement, organizing, etc. to make it clean and attractive, and is also used in large quantities for electrical insulation, industrial purposes, and packaging. In order to cut such an adhesive tape, the user can basically cut it using a knife or scissors without a special cutting device, or use a container-shaped cutting device that is currently sold for adhesive tape.

The method of cutting adhesive tape with a knife or scissors is cumbersome and time-consuming because the user must perform various actions such as holding the adhesive tape, pulling out the tape, cutting or using scissors, and using the cut tape, which reduces work efficiency. do.

In addition, for cutting, you need to have a separate knife or scissors, and if not, you have to use another tool (for example, the user's teeth). In this case, not only is the cutting surface of the tape not smooth, but it also has various disadvantages (such as teeth). damage, hygiene issues, etc.).

In the case of Patent Document 1, a cutting body is provided in a rectangular shape with a thin thickness, a bridge that can be combined with an adhesive tape is provided on both sides of the cutting body, and a means for directly cutting the adhesive tape is provided on the inside of the cutting body. Equipped with a cutter; The cutter includes a cutting blade hole formed in the front of the cutting body to allow a cutting blade for cutting the adhesive tape to enter and exit; a button provided at the rear of the cutting body to select entry and exit of the cutting blade; a locking protrusion provided in an operating hole formed behind the button and the cutting blade hole to prevent the button from being released; an operator provided in front of the operating hole to accommodate a cutting blade and directly connected to the button; An adhesive tape cutting device was proposed that includes a bar spring that is interposed between the front side of the operator and the upper side of the operating hole to always retract the cutter.

However, the adhesive tape can be cut by pulling out the cutting blade from the cutting body by operating a button while it is supported on the branch pipe by the bridge, but after cutting, the adhesive tape sticks back to the roll, making it difficult to find the cut end.

In addition, Patent Document 2 is a center band that extends to cross the inner peripheral surface of the tape roll and has a gap based on the center of the band.

And, a pair of first legs each extending from both ends of the center band to one side of the tape surface, and each extending to the other side of the tape surface while being opened at a certain angle with the first leg relative to the center band. An elastic support section consisting of a pair of second legs; Two supporters separately connecting both ends of the first leg and both ends of the second leg; A blade mounted on a supporter connected to the first leg and having a blade facing the supporter formed on the second leg; It is mounted on the supporter formed between the second legs to seat the expected cutting area of the tape and includes a receiving portion that accommodates the blade of the blade. It is small in size and easy to use, and is compatible with various types of adhesive tapes. A cutting device for adhesive tape that can be conveniently installed and used was proposed.

However, although a portion of the tape roll is mounted between a pair of first and second legs to allow passage, and is configured to support the inner peripheral surface of the tape by a center bar, the structure of the elastic support portion is not clearly specified. Instead, as the adhesive tape is exhausted, the gap between the outer circumference of the tape and the blade widens significantly, causing the control device to become loose, causing separation or separation, as well as safety accidents.
