Abstract

PROBLEM TO BE SOLVED: To form a loop-shaped non-adhesive portion at a cut portion of a cut adhesive tape by using an adhesive force of the adhesive tape when cutting an adhesive tape drawn to an arbitrary length. Can be cut.
The cutting blade was invented for the purpose of a safe adhesive tape cutter that is always stored when not in use and does not expose the cutting blade.
A pressure-sensitive adhesive tape cutter of the present invention uses a pressure-sensitive adhesive force of an pressure-sensitive adhesive tape to move a cutting blade to a predetermined position, and forms a loop-shaped non-adhesive portion when the pressure-sensitive adhesive tape is cut. When the cutting is finished, the cutting blade automatically returns by the action of the spring, and without any operation, the cutting blade can continuously form a loop-shaped non-adhesive portion in one shot and cut.
When the adhesive tape cutter is not used, the cutting blade is always exposed without being exposed, and is stored in the lower part of the lifting base, so that the cutting blade comes out simultaneously with the tape only when the tape is cut.

Description

  The present invention uses a pressure-sensitive adhesive tape cutter to cut a pressure-sensitive adhesive tape that has been drawn out to an arbitrary length, and always uses a pressure-sensitive adhesive force of the pressure-sensitive adhesive tape to form a loop-shaped non-adhesive portion at the cut portion of the cut pressure-sensitive adhesive tape. The present invention relates to an adhesive tape cutter which is formed and can be cut so that the blade portion of the cutting blade is not always exposed except when cutting the tape.

  When an adhesive tape is used, it is often used on the premise that it is peeled off from the beginning. When removing exhibits that are secured with adhesive tape, such as displaying works such as school or kindergarten children, announcements of public offices, public institutions, shops, etc., or removing adhesive tape used for packaging items It is speculated that there is a great demand for an adhesive tape cutter capable of forming and cutting a non-adhesive part.

If you want to peel off the wrapping paper adhesive tape wrapped with clean wrapping paper, I think that there are many people who have made an effort to peel off the sticky adhesive tape.
Even in such a case, when the wrapping paper is stopped with the adhesive tape cut by the adhesive tape cutter of the present invention, the adhesive tape can be peeled off without damaging the wrapping paper, and a gentle caring packaging can be performed.

In addition, lunch boxes sold at convenience stores may also be secured with adhesive tape, but if the end of the adhesive tape is difficult to see and peel off, it should be wrapped with an adhesive tape that has a non-adhesive part. For example, it is easy to find the tip of the adhesive tape, and it can be easily removed.
Therefore, there are many applications for adhesive tape cutters in which the tip of a conventional adhesive tape is looped.
However, all the adhesive tape cutters that have been applied have a problem in safety because the blade portion of the cutting blade is exposed. Accidents due to carelessness of infants and children can occur.

  Since the adhesive tape cutter of the present invention is stored without always exposing the blade part of the cutting blade except when cutting the tape, a safety mechanism that can eliminate injuries such as fingers by the cutting blade It is an invention of a sticky adhesive tape cutter.

The present invention is a tape cutter using the adhesive force of an adhesive tape, and has the following configuration.
(A) A configuration in which an adhesive surface for adhering the adhesive tape is provided on the upper surface of the lifting base.
(B) A configuration in which an eave is provided on the upper part of the lifting base to store the cutting blade below.
(C) A configuration in which the lifting base is pulled up by the adhesive strength of the adhesive tape.
(D) When the lifting base is pulled up, the cutting blade body housed under the eaves of the lifting base is pushed open by the triangular cam mechanism provided at the lower part of the lifting base, and the cutting blade is moved to the adhesive tape cutting position. Configuration to move to.
(E) The cutting blade moved to the tape cutting position is fixed by a stopper.
(F) A configuration in which the stopper is removed when the adhesive tape is cut with the cutting blade at the tape cutting position, and the cutting blade is stored under the eaves of the lifting base.

The effect of the present invention is to peel off exhibitions that have been stopped with adhesive tape from schools, kindergarteners, etc., government offices, public institutions, supermarkets, shops, etc. In addition to being used for ease of use, it is assumed that it will be used when peeling adhesive tapes used to wrap goods, or when sealing envelopes and peeling adhesive tapes for convenience stores. Not to mention infants and the elderly, I am convinced that it will be used in places where all adhesive tape is used, with consideration for people.
In addition, it is an adhesive tape cutter that can ensure the safety of all people who operate the adhesive tape cutter, and it is the only adhesive tape cutter on the market that can always store the cutting blade safely except when cutting the cutting blade. It is a cutter.

  Drawing which shows the state of the adhesive tape cutter and adhesive tape of this invention   Shows a drawing of the lifting platform tape   Detailed view of blade and stopper when cutting tape   Show details of lifting platform   Details of cutting blade and stopper   Shows triangular cams provided on both sides of the lower part of the lifting platform   Shows the sliding part of the cam provided on both sides of the lower part of the cutting blade

In the present invention, when the pressure-sensitive adhesive tape is cut with a pressure-sensitive adhesive tape cutter, the cut portion can always be cut in one shot by forming a non-stick portion in a loop shape. In addition, the structure is simple and the cutting blade of the adhesive tape can be stored so that it is not exposed at all times except when cutting the tape. It can be stored safely.
Embodiments of the present invention will be described below with reference to the drawings.

The Example of the adhesive tape cutter of this invention is described using FIGS.
As shown in FIGS. 1 and 2, when the pressure-sensitive adhesive tape cutter mounted on the roller is pressed against the pulling / uplifting base 14 and the tape is pulled up, the triangular cam 17 provided at the lower part of the pulling-up base 14 is obtained. The cutting blade body 2 is moved in the B direction.
At this time, since the clasp 5 is applied to the notch portion 21 provided in the stopper 4, the cutting blade body stops at a predetermined position.
Therefore, a space that can be looped is created in the cutting portion of the adhesive tape, and the moved cutting blade 15 is stopped at a predetermined position.
When the adhesive tape is cut, as shown in FIG. 3, the adhesive tape picked by two fingers is cut and pulled downward. At that time, a force is applied in the downward direction, and a force is applied to push down the cutting blade body 2 in the downward direction of the arrow. The cutting blade body is pushed up by the force of the spring 9 attached to the lower part, but simultaneously with the cutting of the adhesive tape, the cutting blade body 2 is pushed downward, and the stopper 4 is supported by the stopper cradle 3 at that time. Since the clasp 5 comes off the notch 21 and is attached to the side of the cutting blade body 2 by the force of the spring 10, it is pushed back in parallel to the pulling base 1, and the cut adhesive tape forms a loop and is cut. Is done.
Since the cutting blade that has moved in the direction of the lifting base simultaneously with the cutting of the tape is stored under the eaves portion 20 of the lifting base 14, the cutting blade is safely stored without being exposed. As described above, when the adhesive blade cutter is not used, the cutting blade is always housed in the eaves portion 20 of the lifting base, and is a safety mechanism that can eliminate injuries such as a finger by the cutting blade.

  The cutting blade 15 was attached at an angle with the cutting blade inclined outward as shown in FIG. By inclining the cutting blade 15 outward, the adhesive material of the adhesive tape adheres to the cutting blade when the adhesive tape is cut, and it becomes easy to form the adhesive tape in a loop shape when cutting.

When the pull-up base body 1 is pulled up, a space 16 is formed inside the pull-up base so that the pull-up base moves up and down, and two shafts 6 and 7 are attached to the space. The distance between the axes is the vertical movement distance required to activate the triangular cam 17 attached to the center of the side surface of the lifting base when the adhesive tape loop is lifted with two fingers for the next cutting operation. It was. This cam 17 acts to push open the cutting blade body 2 when the lifting base is lifted. As shown in FIG. 5, the cutting blade body was provided with a square cam sliding portion 18 corresponding to a triangular cam at the lower center.
Triangular cams 17 provided on the pulling base 14 and sliding portions 18 provided on the lower part of the cutting blade main body 2 can also be provided on both sides of the lower part of the main body as shown in FIGS.
When cams and sliding parts are provided on both sides of the lower part of each body, when the adhesive tape is pulled up, the cam and sliding parts are installed in the center when the adhesive tape is lifted to the left or right of the lifting base. Compared with the case of the case, it can be lifted more stably on the both sides, but it was also confirmed that there is not much difference in practical use.

In the next cut of the adhesive tape, when the loop portion 11 (FIG. 1) of the adhesive tape is pulled up, the pulling base 1 can be pulled up in the direction of the arrow by the adhesive force of the adhesive tape as shown in FIG. At this time, the triangular cam 17 attached to the center of the lower part of the pulling table moves upward. The triangular cam slides a sliding portion 18 of the cam provided at the lower center of the cutting blade body 2 to push the cutting blade body at a predetermined angle (arrow B).
The cutting blade main body 2 opened at that time is stopped by the clasp 5 engaged with the notch 21 defined in the stopper 4 attached to the shaft 6 of the lifting base. The length from the axis 6 of the fulcrum of the stopper to the notch 21 at the stop position is related to the size of the loop formed by the adhesive tape when the adhesive tape is cut. Of course, if the length from the fulcrum of the stopper to the stop position is increased, the loop of the adhesive tape at the time of cutting becomes larger. The stopper is the weight of the stopper main body, and is always pushed downward. However, since the stopper is supported by the stopper support 3, it does not fall below that. The strength of the pressure of the spring 10 is set to a pressure that does not cause resistance when the cutting blade body moves by lifting the loop-shaped non-adhesive portion.

In the adhesive tape cutter of the present invention, the size of the loop 11 that forms the non-adhesive part at the time of cutting is one half of the length of the cutting blade 15 stopped at the notch part 21 of the stopper 4 and the eaves part 20 of the fixing base. It becomes the size of.
As shown in FIG. 3, the cutting blade body 2 is provided with a sleeve 19 through which a shaft passes. The sleeve was elliptical so as to move up and down about 2 mm, and a spring 9 was attached to the bottom of the cutting blade body 2. The shaft 8 that supports the cutting blade body with the pressure of the spring is always located at the lower part of the sleeve.

The cut part of the cut adhesive tape can form a non-adhesive part in the cut part by forming a loop 11 having a predetermined size with the adhesive surface inside.
By repeating the above operation using the adhesive force of the adhesive tape, it is possible to cut the adhesive tape by forming a loop-shaped non-adhesive portion with one shot similar to a commercially available adhesive tape cutter.

Since the cutting blade that has moved in the direction of the pulling table simultaneously with the cutting of the tape is stored under the eaves portion 20 of the pulling table 14, the cutting blade is safely stored without being exposed. As described above, when the adhesive blade cutter is not used, the cutting blade is always housed in the eaves portion 20 of the lifting base, and is a safety mechanism that can eliminate injuries such as a finger by the cutting blade.
As a result of the experiment, a loop-shaped non-adhesive part was formed and cut when cutting adhesive tapes of all the currently available adhesive tapes (12 mm width, 15 mm width, 18 mm width, 24 mm width). I confirmed that I can do it.

If the adhesive tape cutter of this invention is used, the front-end | tip of the cut adhesive tape can always be cut | disconnected in a loop, and a fixed non-adhesion part can be formed by one shot.
Moreover, except when cutting adhesive tape, the blade part of the cutting blade is stored in the eaves part of the fixed base, and the cutting blade is not exposed to the outside at all times. Can be cut.
I am convinced that many people who use the adhesive tape cutter of the present invention can contribute to convenience and safety.
