Description

The present invention relates to an instrument that is attached to the top lid of a general conventional roll paper holder to enable cutting of roll paper with one hand.

The conventional one-handed roll paper holder has a problem that it is heavier than a general holder, difficult to pull out, and difficult to handle because it uses a simple method of cutting the paper by simply making the top lid heavier. (For example, refer to the product name TOTO Cigarette Plastic Resin Pastel Ivory YH500 # SR2). There was also an adapter type of the same type as the present invention (see Utility Model Registration Nos. 3211031 and 3214977), but it is practical because it must be cut with an upward fixed blade, which is dangerous. It wasn't.

The conventional one-handed roll paper holder uses a method in which the top lid of the holder is heavier and the paper is pulled upward to cut, so when pulling out the tip of the roll paper, it is compared to a normal holder. There was a problem that it was heavy and difficult to pull out.
Further, in order to use the paper again after cutting it, it is necessary to turn the roll paper with a finger to pick up the tip of the paper when pulling out the paper, which is a problem in terms of hygiene.
There is also an adapter method similar to the present invention, but since the cutting blade is always facing upward, there is a risk of finger injury, and it cannot be used especially for people with eye diseases. Met.
There are also mechanical ones, but none are cheap enough to be used at home.

The present invention is a one-handed type that can be easily attached to the top lid of a conventional general inexpensive roll paper holder, can be easily used cleanly with one hand, and can be used safely with or without perforations. It is intended to provide a roll paper cutting tool.

In order to achieve the above problems, in the one-handed roll paper cutting tool of the present invention, a horizontally long opening for pulling out the end of the roll paper is provided near the center of the front portion of the base plate, and the upper portion of the opening is provided. A locking portion having a V-shaped cross section was provided to hook onto the tip of the upper lid of the existing roll paper holder, and a substantially linear shape was formed at the lower part of the upper edge of this opening to stabilize the paper withdrawal. By forming the friction part and the contact part for pressing the roll paper in the vicinity of the upper part of the friction part in a smooth surface shape, and further providing the double-sided adhesive tape as a sticking body on the upper surface of the trailing edge of the base plate, This opening makes it easy to attach the existing roll paper holder to the top lid, and to slide your finger to make it easier to pick and pull out the paper and to prevent the paper edge from falling off into the opening after cutting. A protrusion is provided in the center of the lower edge and finger hooks are provided on both sides. Then, for safe use, a rotary cutter formed in a T-shaped cross section consisting of a rotary cutter cutting blade, a rotary cutter friction portion, and a rotary cutter weight portion is provided on the front portion of the substrate plate for safety. It was configured so that it could be used.

The one-handed roll paper cutting tool configured as described above is attached to the top lid of the existing roll paper holder (Fig. 1). When using (Fig. 4), lightly insert your finger into the finger hooks on both sides of the opening and slide your finger toward the center of the protrusion to pick up the exposed paper edge and diagonally upward. By pulling out as much as possible and then pulling down (Fig. 2), the contact part gives friction to the roll paper to weaken the movement, and then the end of this paper applies the rotary cutter friction part provided on the front edge. By pressing, the rotary cutter is rotated, and then the rotary cutter cutting blade is triggered to cut (FIG. 3). Then, since the new end of the paper is always exposed after cutting, this exposed portion can be picked up and pulled out when it is used again. The rotary cutter is formed by adjusting the balance so that the rotary cutter cutting blade returns to the original state in which it is contained in the rotary cutter cutting blade receiving portion by the action of the rotary cutter weight portion.

Further, it is preferable that the main body cutting blade can be used as a spare cutting blade when the rotary cutter comes off (FIG. 5).

By using the one-handed roll paper cutting tool of the present invention, when used, any one hand may be closed or blind, with or without perforations. You can now safely cut roll paper by length. As a result, work efficiency has improved dramatically.

The one-handed roll paper cutting tool of the present invention uses a tool if it is an existing roll paper holder with an upper lid by adopting a method of attaching to the upper lid of the existing roll paper holder with a hook and double-sided adhesive tape. It can be easily attached to most types of products without the need for it. Therefore, it has become possible to change to a one-handed roll paper cutting tool inexpensively and easily.

Further, in the one-handed roll paper cutting tool of the present invention, the paper can be easily picked up and pulled out by providing a protrusion and a finger hook at the opening, and at the same time, the exposed portion of the paper tip after cutting is formed. It prevents the problem of falling down from the opening. In addition, the friction part at the bottom of the upper edge of the opening can generate stable friction when pulling out, making it easier to pull out the paper edge, and the contact part weakens the movement of the roll paper when cutting, so it cuts more. It became easier.

In addition, by adopting a rotary cutter, it has become possible to cut more safely.

And, unlike the conventional method of turning the roll paper with a dirty hand that may be dirty and pulling out the end of the paper, it is possible to constantly expose the new clean paper tip in a stable manner. It has become possible to meet the demands of restaurants, long-term care facilities, hospitals, etc., which are workplaces required for hygiene.

In claim 2, the structure is such that two cutting blades, a main body cutting blade and a rotating cutter, are provided side by side, so that if the rotating cutter is damaged and falls off for some reason, the main body cutting blade serves as a spare function. You can now cut the paper again.

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1, 2, and 3.
In order to achieve the above problems, in the one-handed roll paper cutting tool of the present invention, (FIG. 1) the upper portion of the plate-shaped substrate plate 1 is bent along the lower surface of the upper lid 8a of the roll paper to give a slight angle. A horizontally long opening 2 is provided near the center of the front portion of the substrate plate 1, and a friction portion 2b formed substantially linearly and an upper edge of the opening 2 are provided at the lower portion of the upper edge of the opening 2. A locking portion 3 formed in a V-shaped cross section is provided on the upper portion of the portion, and a protrusion 2c is provided near the center of the lower edge portion of the opening 2. By providing the protrusion 2c, finger hooks are provided on the left and right sides of the opening 2. Form 2a. Then, even if the back surface of the substrate plate is reduced by using the roll paper, the contact portion 6 is formed at a position where the vicinity of the upper portion of the roll paper is always pressed. Further, side plates 11 are provided on both sides of the substrate plate 1, and a rotary cutter cutting blade 44a, a rotary cutter friction portion 44b, and a rotary cutter weight portion 44c are formed in the vicinity of the tips of the both side plates 11 in a T-shaped cross section. The formed rotary cutter 44 is pivotally supported so as to be bridged by the rotary bearing 44e. Then, a rotary cutter cutting blade receiving portion 4 is formed on the leading edge of the base plate 1 so that the rotary cutter cutting blade 44a of the rotary cutter 44 can be accommodated, and further, both sides are formed near the upper surface of the trailing edge of the substrate plate 1. The problem is solved by providing the adhesive tape 5.

The method of attaching to the existing roll paper holder will be described.
In order to attach the one-handed roll paper cutting tool of the present invention (hereinafter, the product of the present invention) to the existing roll paper holder 8 (hereinafter, the paper holder), first, in the recess formed in the cross section V shape of the hooking portion 3. The tip of the upper lid 8a is hooked, and the double-sided adhesive sheet 5 is attached to the inside of the upper lid 8 for mounting. By doing so, it is possible to prevent the product of the present invention from falling off from the upper lid 8a without fixing the tip of the upper lid to the hooking portion 3.

The procedure of use is explained. See Figures 1, 2, 3 and 4.
To make the new roll paper 7 just attached to the paper holder available for the first time, the paper end 7a is pulled out from the inside to the outside of the opening 2. When using the paper, slide the end 7a of the paper along the inclination of the protrusion 2c with a finger, pinch it diagonally upward in the center, and then pull it out (a). At this time, the upper lid 8a is lifted upward together with the product of the present invention, the contact portion 6 between the roll paper 7 and the product of the present invention is separated, and the paper 7a can be easily pulled out. At this time, in the paper to be pulled out, the total weight of the product of the present invention and the upper lid 8a is added to the friction portion 2b at the lower part of the upper edge of the opening 2, and an appropriate frictional resistance is generated.

Next, after pulling out the paper of the required length, lower the paper end 7a downward (b). Then, due to the weight of the product of the present invention and the force of pulling the upper lid 8a and the paper end portion 7a downward, the contact portion 6 presses the roll paper 7, and the movement of the roll paper 7 becomes weak. The paper 7a rotates the rotating cutter 44 around the rotating shaft 44d so as to push down the rotating cutter friction portion 44b (e). At the same time, the paper is caught by the rotary cutter cutting blade 44a, and the rotary cutter weight portion 44c is rotated about 90 degrees until it hits the back surface of the substrate plate to stop (c). As a result, the paper can be cut by the tension and the stationary rotary cutter cutting blade 44a. Then, after the paper has been cut, the rotary cutter 44 stops in a state where the rotary cutter cutting blade 44a is accommodated in the rotary cutter cutting blade receiving portion 4 due to the weight of the weight portion 44c.

As a result, the state of the paper holder after cutting the paper is exposed by the length from the friction portion 2b required for picking and pulling out to the rotary cutter cutting blade 44a when the paper is cut. The tip of the roll paper can be held at all times.

When the rotary cutter 44 is not operating, the rotary cutter friction portion 44b is always kept facing upward due to the weight of the rotary cutter weight portion 44c. Then, at the time of cutting the paper, the rotary cutter cutting blade 44a faces upward, and the rotary cutter weight portion 44c abuts on the back surface of the leading edge of the main body to be in a stationary state. It is configured.
It should be noted that this rotary cutter does not necessarily have to have a T-shaped cross section as long as it has a cutting blade, a friction portion, and a weight portion and can exhibit the above functions.

When using (see FIGS. 1, 3, and 4), put your fingers in the left and right finger hooks 2a, slide them onto the protrusions 2c, and pick up the required length diagonally upward to pull out the paper downward. Lower toward (a) (b).
In this way, the rotary cutter cutting blade 44a does not face upward except when the paper is pulled out and cut, and it can be used safely because it is in contact with the rotary cutter cutting blade receiving portion 4 and is held in a state of being settled. be.

In FIG. 5, when the rotary cutter 44 is damaged for some reason and falls off, the paper can be cut again by providing the main body cutting blade 44f.
