ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an adhesive tape dispenser which is widely used as stationery, and more particularly, to an adhesive tape dispenser which has an automatic drawing and cutting means, so that an user may use an adhesive tape conveniently.
DESCRIPTION OF THE PRIOR ART
In general, adhesive tape dispensers have an opening at one side thereof through which an adhesive tape is detachably mounted. Most of the conventional adhesive tape dispensers have a saw toothed cutting blade which is integrally formed or detachably located at a front end part thereof so that a free end part of the adhesive tape is drawn from the tape dispenser and cut by the saw toothed cutting blade. After cutting, the free end part of the adhesive tape is attached on a shoulder part formed under the saw toothed cutting blade for next use.
Therefore, if users want to use the adhesive tape in the conventional adhesive tape dispenser, they have to detach the adhesive tape attached on the shoulder part of the tape dispenser with finger, pull it as long as necessary, put it on the saw toothed cutting blade and strain downward so that the adhesive tape can be cut. However, all of these procedure should be taken manually and inconveniently, and an adhesive strength of the adhesive tape is weakened by fingerprints or dirt, since the users grasp the adhesive tape with finger during using it.
SUMMARY OF THE INVENTION
An object of the present invention is to provide an adhesive tape dispenser having an automatic drawing and cutting means which may automatically draw out the adhesive tape as long as necessary without pulling it with hand and automatically cut it clean by a cutter, so that the user may use the adhesive tape conveniently.
To achieve the object the adhesive tape dispenser according to the present invention includes a gun-shaped case body having a detachable cover, a drawing means for drawing an adhesive tape from the case body, and having a trigger handle protruded outwardly from one side of the case body and a pair of drums rotating in integration with the trigger handle, and a cutting means for cutting the adhesive tape which is drawn by the drawing means from the dispenser, and having a handling member mounted on a gunbarrel portion of the case body, a lever interlocking with the handling member and a cutter mounted at a front end of the lever.
The adhesive tape dispenser according to the present invention may draw the adhesive tape from the case body as long as necessary by putting a finger on the trigger handle and pulling the handle several times without directly pulling the adhesive tape with hand, and may cut clean the drawn adhesive tape by the cutter when the user pulls the handling member.
