Description

[Technical field]

[0001] The present invention is useful for cutting rolled paper, and is primarily concerned with using toilet paper on a table, etc. [Background technology]

[0002] Conventional roll paper cutters have mainly been proposed that are slightly larger than an unused roll of paper, and that pull out and cut the roll paper while the main body is in place (see, for example, Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2012-417888 A [Patent Document 2] JP 2013-244080 A Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention is intended to be used mainly for toilet paper in the living room. There are types of tabletop toilet paper cutters that rotate and pull out the toilet paper, but most of them are a size larger than toilet paper and difficult to use. Toilet paper, which is used instead of daily tissues, is often moved within reach due to people's actions, so it is ideal to use it at hand, easy to grab, just like naked toilet paper. In order to solve the above problems, the objective is to provide a roll paper cutter that is easy to hold, simple, and can cut toilet paper easily. [Means for solving the problem]

[0005] A roll paper cutter according to a first aspect of the present invention is a roll paper cutter for cutting roll paper, comprising: a main body portion formed of a substantially arc-shaped plate having a cut portion for covering the roll paper; The roll paper roll holder includes a first support section extending from the upper end of the main body section toward the roll paper side, a second support section extending from the lower end of the main body section in the same direction as the first support section, and a shaft located inside the core of the roll paper. the first support portion has a first slot, and the second support portion has a second slot; The shaft is provided with a slide mechanism that can be hooked on the first and second elongated holes to move toward and away from the main body.

[0006] A roll paper cutter according to a second aspect of the present invention is the roll paper cutter according to the first aspect, The slide mechanism is characterized in that it has a first holding portion and a second holding portion in the directions in which the upper and lower ends of the shaft are extended, respectively, and the first holding portion is hooked onto the upper edge of the first long hole, and the second holding portion is hooked onto the lower edge of the second long hole, allowing the shaft to move along the long holes.

[0007] A roll paper cutter according to a third aspect of the present invention is the roll paper cutter according to the second aspect, The device is characterized in that either the first pressing portion or the second pressing portion is at least removable from the shaft, or the shaft is capable of being separated and joined into two parts, upper and lower, making it possible to load and remove the roll paper. Effect of the Invention

[0008] The roll paper cutter of this invention has a simpler structure and is smaller than conventional roll paper cutters, so it can be easily grabbed from any direction and brought close to hand, making the paper cutting action almost the same as handling bare roll paper. Because the shaft is movable, the cutting part can come into contact with the paper regardless of how much is left in the roll, and the required length of roll paper can be neatly cut even without following the perforations. In addition, when the roll paper is placed vertically after cutting, the cut ends are covered by the main body and do not hang down, keeping the whole piece beautiful.

[Figure 9] 2A to 2C are explanatory diagrams illustrating a method of using the roll paper cutter of FIG. 1. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Fig. 1 is a perspective view illustrating a roll paper cutter according to one embodiment of the present invention. Figs. 2 to 6 are drawings of the roll paper cutter of Fig. 1 viewed from various angles. The roll paper cutter 20 in the illustrated example is applied to toilet paper that is primarily placed on a table or the like. The roll paper cutter 20 extends from the upper and lower ends of the main body 1 and has first support parts 6 and second support parts 7 for supporting the shaft 3 that penetrates the inside of the roll paper core from above and below and for allowing it to move in a direction toward and away from the main body 1.

[0011] The main body 1 is positioned radially outward of the vertically placed roll paper 13 and has cutting parts 2 on both ends that extend across at least the entire width of the roll paper 13 so that it can be used with either the left or right hand. The shaft 3 is located inside the core of the paper roll 13. The first support part 6 and the second support part 7 extend toward the paper roll side at the upper end and lower end of the main body part 1, respectively, and support the shaft 3 so that it can slide toward and away from the main body part 1.

[0012] The first support part 6 and the second support part 7 each have a first long hole 8 that extends in the direction toward and away from the main body part 1, and a second long hole 9 that is the same shape as the first long hole 8 and extends in the same direction. The shaft 3 has a first pressing part 4 at its upper end and a second pressing part 5 at its lower end. The first pressing part 4 in FIG. 7 hooks onto the upper edge of the first long hole 8, and the second pressing part 5 hooks onto the lower edge of the second long hole 9. This allows the shaft 3 to slide along the first and second long holes in the direction toward and away from the main body part 1 without falling out.

[0013] FIG. 7 is a cross-sectional view of the roll paper cutter 20, with an overall cross-sectional view and a partially enlarged cross-sectional view arranged side by side. In order to load the roll paper 13, either the first pressing part or the second pressing part must be at least removable from the shaft 3, or the shaft 3 must be capable of being separated and joined into two parts, one above the other. In the example of FIG. 7, the first pressing part and the shaft 3 are detachably connected by screwing the male thread 11 of the first pressing part into the female thread 12 of the shaft 3. As an alternative to connection by screws, they may be detachably connected by fitting a convex part of one into a concave part of the other and being held in place by friction. The position at which the shaft 3 is separated and joined into two parts, one above the other, is free. In the case where the shaft is not passed through the long hole, it may be made thinner than the shaft diameter and extended, the extended portion may be passed through the long hole, and a hook portion may be provided at the end.

[0014] According to the JIS standard, toilet paper is sized with a paper width of 114mm±2mm, an inner diameter of the core of 38mm±1mm, and a roll diameter of 120mm or less, so the height of the main body 1 is preferably about 120mm, which is a little larger than the paper width specified by the JIS standard. Also, in order to allow the main body cutting part 2 to come into contact with the toilet paper regardless of the amount of paper remaining, the shape of the main body in plan view is roughly arc-shaped with a thickness of about 2-4mm, and the overall width is preferably about 33mm, which is shorter than the outer diameter of the toilet paper core of about 40mm, and the cutting part 2 provided on the main body 1 is at an angle that makes it easy to cut the paper.

[0015] FIG. 8 is a perspective view illustrating the roll paper cutter 20 set on the roll paper 13. As shown in FIG. The shaft 3, which is located inside the roll paper core and rotates the main body 1, first support part 6, and second support part 7, is preferably cylindrical in shape with a diameter of about 10 mm, taking into consideration its function and the connection to the main body 1. For the first pressing part 4 and the second pressing part 5, it is preferable that they are both disk-shaped with a diameter of about 20 mm, taking into consideration ease of handling, but their shape is free as long as they can be caught in the long holes and the shaft 3 can be moved toward and away from the main body 1.

[0016] Most commercially available roll papers have an inner diameter of the core that is smaller than the roll thickness of the paper (half the roll diameter minus the outer diameter of the core). In the sliding mechanism, the shaft 3 moves along the long hole toward the body 1 so that the body approaches the core as the paper is reduced and eventually makes contact with it. It is preferable that the range of the first long hole 8 and the second long hole 9 is such that, when an unused roll of paper is attached to the roll paper cutter 20, the shaft 3 can move in a direction toward or away from the main body 1, causing the main body 1 to come into contact with the roll paper core.

[0017] FIG. 9 illustrates an example of how the roll paper cutter 20 is used by a right-handed person. The roll paper cutter 20 is attached, the main body 1 is placed on the right side of the roll paper 13 in the left palm, the paper is laid down, and the right hand grasps the scrap of paper and rotates the roll paper to pull out the required amount, after which the main body 1 is pressed with the fingers toward the core of the roll paper. This brings the cutting part 2 into close contact with the roll paper 12, allowing the paper to be cut with the right hand. Because the shaft 3 is able to slide, the gap between the shaft 3 and the main body 1 is always larger than the thickness of the roll of paper. Therefore, when you remove your finger pressure after cutting the paper, the main body 1 located on the side of the roll that has been laid on its side will shift downward under its own weight, revealing the scraps of paper that were hidden by the main body 1 and making it possible to pull out the next roll of paper. The cutting section is provided on both sides of the main body, so if the user is left-handed, the roll paper can be loaded in the opposite direction to use it.

[0018] The roll paper 13 with the roll paper cutter 20 set on it is basically placed vertically, and it is preferable to provide a recess 10 on the bottom surface of the second support part 7 around the edge of the second long hole 9 in the range where the second pressing part 5 at the bottom of the shaft moves (see Figures 3 and 7). This prevents the second pressing part 5 from going below the bottom surface of the second support part 7, so that the roll paper 13 can be kept stably placed vertically. The second support portion 7 may have any shape as long as it has the second long hole 9 and is large enough to hold the unused roll of paper 13 in a stable state without tilting.

[0019] The first support part 6 can have any shape as long as the long hole is provided in the same radial direction of the roll paper as the second support part 7, but considering the overall design of the roll paper cutter 20, it is preferable that the first support part 6 has the same shape as the second support part 7. Also, providing a cover on the top makes for a simpler and more streamlined design.

[0020] Considering the use and shape of the present invention, it is suitable to make it out of plastic, which is lightweight and easy to mold into any shape, and it will blend in with the interior design with wood grain, floral patterns, etc. Also, as a high-end version, it can be made out of lightweight metal with embossing or laser engraving.
