JP7530153B2 - A handy-sized tape cutter that can also make gussets on adhesive tape - Google Patents

Description

This invention relates to a handy-sized tape cutter that can also make gussets in adhesive tape.

Although products that can create gussets in adhesive tapes have been developed, they have not yet become widespread on the market (see Patent Document 1).
The likely reasons for this are the complex structure and the number of components, which would make it too costly to commercialize.

Utility Model Registration No. 3117560

This posed the following problems:
Because the tape cutter utilizes the tension generated when the tape is pulled out, it needed to be heavy and large enough to withstand it.
This requires tension on the tape, which causes the tape to stretch and deform.
The present invention has been made to solve these problems.

The handy-size tape cutter of the present invention is a handy-size tape cutter that sets an adhesive tape and has a cutter blade for cutting the adhesive tape, and is characterized in that it has a push-up plate that is provided between the cutter blade and the pull-out opening of the adhesive tape and pushes up the adhesive surface of the pulled-out adhesive tape from below with its tip, causing the adhesive tape to bend upward , and a reverse rotation prevention roller is provided at the tip of the push-up plate, which rotates in the pull-out direction of the adhesive tape it comes into contact with but does not rotate in the wind-up direction .

The push-up plate pushes the adhesive surface of the adhesive tape upward from below to create the crotch, and pulls out the amount of adhesive tape needed to form the crotch. This means there is no need to pull out the adhesive tape needed to create the crotch first, making it possible to make the device small and lightweight, and ideal for a handy-sized tape cutter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings .
See Figure 2 (1). The handy type tape cutter body (1) of the present invention is equipped with a push-up plate (5) , a rotating table (3) biased by a spring (7) , and a connecting rod (4) for interlocking the push-up plate (5) and the rotating table (3) .
The main body case (2) is provided with a cutter blade (16) for cutting the tip of the adhesive tape (17), an adhesive stand (15) for adhering the tip of the cut adhesive tape (17) , a support shaft A (9) and a support shaft B (19).
See Figure 4. The rotating table (3) is provided with an operating lever (8) and a rotating table connecting part (10) for connecting with a screw or the like, and the connecting rod connecting part A (11) and the rotating table connecting part (10) are connected with a screw or the like to allow them to move freely.
Also, the connecting rod connecting bar (12) is inserted into the push-up plate connecting hole (13) so as to be able to move freely.
Furthermore, the support shaft B (19) is inserted into the support hole (14) of the push-up plate to allow the push-up plate (5) to move freely.
By connecting them, when the operating lever (8) is operated, the rotating table (3), the connecting rod (4), and the push-up plate (5) are linked . Next , we will explain the process of creating the gores using a handy-sized tape cutter.
See Figure 2 (2). The adhesive tape (17) is set on the handy size tape cutter body ( 1), and the tip of the adhesive tape (17) is pulled out and adhered to the adhesive stand (15).
See Figure 3 (2). When the operating lever (8) is lowered downward, the connecting rod (4) connected to the rotating table (3) and the push-up plate (5) start to move in unison, and the connecting rod (4) side of the push-up plate (5) starts to move downward around the support shaft B (19) , while the reverse rotation prevention roller (6) side starts to move upward .
The push-up plate (5) on the side of the reverse rotation prevention roller ( 6) moves in an arc, pushing up the adhesive surface of the adhesive tape (17) from below and trying to pull out the adhesive tape (17).
See Figure 6 (2). At this time, the roller (20) of the reverse rotation prevention roller (6) is in contact with the adhesive surface of the adhesive tape (17), and when the adhesive surface of the adhesive tape (17) is pushed up from below to be pulled out , the roller (20) is subjected to a load in the direction of pulling out , and the connecting bridge (21) tilts toward the roller stopper (23).
The roller stopper (23) prevents the roller (20) from rotating, and the adhesive force with the adhesive tape (17) pushes up the adhesive surface of the adhesive tape (17) from below, allowing it to be pulled out upward .
The pulled out adhesive tape (17 ) and the adhesive tape (17) attached to the adhesive base ( 15) bend upwards with the adhesive surface downwards , and when the bend is pinched, the gusset is completed. See Figure 3 (2).
When the operating lever (8) is released to pinch the gusset and pull out the adhesive tape (17), the rotating table (3) returns by the force of the spring (7) , and the roller (20) leaves the roller stopper (23) and is stopped by the connecting bridge stopper (22).
See Figure 6- (3).
The roller (20) is no longer loaded and returns to the state shown in FIG. 2-(2) while rotating.
The required amount of adhesive tape (17) is pulled out and cut with a cutter blade (16) to complete the adhesive tape (17) having gussets .

The present invention has the above-mentioned structure, but by changing the installation position of the operating lever (8), versatility can be created and ease of use for the user can be improved .
Moreover, a simpler structure can be achieved by biasing the push-up plate itself with a spring or the like.
By closing the case lid when not in use, dust-proofing and hygienic effects can be achieved, and the device can be stored in a pocket or the like and carried around at medical and work sites, improving ease of use.

The present invention has been described above based on an embodiment, but the present invention is not limited to the above embodiment, and modifications may be made without departing from the spirit of the present invention, and other technologies may be appropriately combined to the extent possible.
