Description

Technical Field

[0005]

[0001] The present invention relates to a device that can be attached to the upper lid of a general conventional roll paper holder and enables the roll paper to be cut with one hand.

Background Art

[0002] In the conventional attachment-type roll paper cutter, since there is a cutting blade at the front edge of the holder, it is dangerous because this cutting blade touches the finger when in use. (Utility Model Registration No. 3214977) Also, when picking up and pulling out the exposed paper end, it was difficult to operate because of its difficult-to-pull-out shape. (Japanese Patent Application Laid-Open No. 2019-022618)

Summary of the Invention

Problems to be Solved by the Invention

[0005] In the conventional single-handed roll paper holder, since a method of cutting by lifting the paper upward by making the upper lid of the holder heavy is adopted, there is a problem that it is heavier and more difficult to pull out compared to a normal holder when pulling out the tip of the roll paper. Also, in order to use the paper again after cutting, when pulling out the paper, the roll paper had to be rotated with a finger to make the tip of the paper pickable, so there was also a problem in terms of hygiene. Furthermore, there are attachment-type roll paper cutting tools similar to this invention, but they posed a risk of injuring one's fingers when used.

[0006] The present invention aims to provide an attachment-type, one-handed roll paper cutting tool that can be easily attached to the top lid of a conventional, inexpensive roll paper holder, can be easily and cleanly used with one hand, and can be used safely regardless of whether the roll paper has perforations or not. [Means for solving the problem]

[0007] To achieve the above objectives, the attachment-type one-handed roll paper cutter of this invention features a horizontally elongated opening near the center of the front of the base plate for pulling out the end of the roll paper, a substantially V-shaped locking portion at the top of this opening for hooking onto the tip of the top cover of an existing roll paper holder, a substantially straight friction portion formed at the lower part of the upper edge of this opening for stabilizing the pulling out of the paper, and a surface-shaped contact portion near the top of this friction portion for holding down the roll paper, and by providing an adhesive body on the upper surface of the rear edge of the base plate, it is made easy to attach to the top covers of existing roll paper holders of different shapes, and a bottom plate is placed over the lower part of the side plates provided on both sides of the front of the base plate to make it easier to grasp and pull out the paper by sliding the fingers, a partition plate is provided near the center of the bottom plate, a finger protection guide formed in an inverted L-shape in cross-section is placed over both side plates from the front edge of the bottom plate upwards, and a cutting blade is provided in a straight line on the front edge of the finger protection guide so that the fingers do not come into contact with the cutting blade.

[0008] The attachment-type roll paper cutter, configured as described above, is attached to the top cover of an existing roll paper holder (Figure 1). (Figure 2) When using it for the first time, pull the end of the paper diagonally upward from the opening, then lower it and cut it with the cutting blade. This will expose the end of the paper from the opening to the cutting blade. When using it again, slide the bottom plate with your fingers, pinch the end of the paper so that it converges towards the central partition plate, pull it diagonally upward as needed, then lower it and cut it with the cutting blade (Figure 3). [Effects of the Invention]

[0009] By using the attachment-type one-handed roll paper cutter of this invention, it is now possible to safely cut roll paper to any length, regardless of whether it has perforations or not, even when one hand is occupied or when the user is blind. As a result, work efficiency has been dramatically improved.

[0010] The attachment-type one-handed roll paper cutter of this invention employs a method of attachment to the top cover of an existing roll paper holder using a latch and double-sided adhesive tape. As a result, it can be easily attached to most types of existing roll paper holders with a top cover without the need for any tools. Therefore, it is now possible to easily and inexpensively convert to a one-handed roll paper cutter.

[0011] Furthermore, the attachment-type one-handed roll paper cutting tool of this invention has a structure in which a base plate is placed across both side plates, and a partition plate is provided in the center of this base plate, making it easier to grasp when pulling out the paper. Furthermore, the design, which incorporates finger protection guides across both side panels, helps to reduce the risk of injuring your fingers when gripping and pulling out the paper by its edge.

[0012] Furthermore, unlike the conventional method of turning the roll of paper with potentially dirty hands to pull out the end of the paper, this method ensures that a fresh, clean paper tip is always reliably exposed, thus meeting the demand in workplaces where hygiene is particularly important, such as restaurants, nursing homes, and hospitals. [Brief explanation of the drawing]

[0013] [Figure 1] This is a cross-sectional view AA of perspective drawing 3, and a diagram showing the operating state of the present invention. [Figure 2] This is a partial cross-sectional view of the product in use. [Figure 3] This is a perspective view of the present invention in a state where the edge of the paper is being pulled down and cut. [Figure 4] This is a perspective view of the present invention. [Modes for carrying out the invention]

[0014] The embodiments of this invention will be described below with reference to Figures 1, 2, and 3. To achieve the above objectives, the attachment-type one-handed roll paper cutting tool of the present invention (Figure 1) is formed by bending the rear of a plate-shaped base plate 1 to follow the lower surface of the top cover 8a of the roll paper at a slight angle, and a horizontally elongated opening 2 is provided near the center of the front of the base plate 1. A friction portion 2a formed in a nearly straight line is provided at the lower part of the upper edge of this opening 2, and a locking portion 3 formed in a V-shape in cross-section is provided at the upper part of the upper edge of this opening 2. Furthermore, a contact portion 6 is formed in a position that always presses against the upper part of the roll paper even when the lower surface of the base plate is worn down by using the roll paper. Furthermore, the problem is solved by providing side plates 11 on both sides of the front of the base plate 1, placing a bottom plate 11a across the lower part of these side plates 11, providing a partition plate 12a in the upper center, providing a finger protection guide 12 with a roughly inverted L-shaped cross-section on the lower edge of the bottom plate 11a, providing a cutting blade 4 on the front edge of the finger protection guide 12, and providing double-sided adhesive tape 5 near the upper rear surface of the base plate 1.

[0015] Describe the method of attaching to an existing roll paper holder. To attach the attachment type single-handed roll paper cutter of the present invention (hereinafter referred to as the product of the present invention) to an existing roll paper holder 8 (hereinafter referred to as the paper holder), first, hook the tip of the upper lid 8a on the depression formed in the V-shaped cross-section of the hooking portion 3, and then attach and mount it to the inside of the upper lid 8 with the double-sided adhesive sheet 5. By doing so, it is possible to prevent the product of the present invention from falling off the upper lid 8a even without fixing the tip of the upper lid and the hooking portion 3.

[0016] Describe the usage procedure. Refer to FIGS. 1, 2, 3, and 4. To be able to use the new roll paper 7 just mounted on the paper holder first, pull out the paper end 7a from the inside to the outside of the opening 2. When using, pick up the paper end 7a with a finger and pull it obliquely upward (a). At this time, the upper lid 8a is lifted upward together with the product of the present invention, and the contact portion 6 between the roll paper 7 and the product of the present invention is separated, reducing friction and making it easier to pull out the paper.

[0017] Next, when the paper of the required length has been pulled out, lower the paper end 7a downward (b). Then, the weight of the product of the present invention and the weight of the upper lid 8a can stop the movement of the roll paper 7, generating tension in the pulled-down paper and making it easier to cut. (c)

[0018] As a result, the state of the paper holder after cutting the paper can always maintain the state of holding the length of the tip of the roll paper exposed by the length from the friction portion 2a to the cutting blade 4 required for picking and pulling out next.

[0019] When continuing to use (refer to FIGS. 1, 2, and 3), slide the fingers from above the exposed paper end inward from both sides toward the inside of the left and right bottom plates lla and move them closer to the partition plate 12a to pick up, then pull out the required length obliquely upward, lower the paper downward, and cut.
