[Technical field]

[0001] The present invention relates to a roll paper cutter that can be retrofitted to the cover of a toilet paper holder or the like that holds rolled paper (roll paper), enabling the paper that has been pulled out to a predetermined length to be easily cut. [Background technology]

[0002] A roll paper cutter of this kind is known as described in Patent Document 1. The roll paper cutter described in this document is fixed to the cover of a toilet paper holder using double-sided tape or the like, and the tip of the cutter is formed into an approximately inverted eight shape or a mountain shape, making it easier to cut the paper that is pulled out, and the tip of the cut paper fits into the tip of the approximately inverted eight shape or mountain shape, making it easier to pick up the tip of the paper the next time it is used. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2001-20045 A DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0004] However, the roll paper cutter described in Patent Document 1 above has the following problems. That is, 1. After the paper is cut, the tip of the paper is held in place by fitting into the tip of an inverted eight or mountain shape, leaving the tip exposed from the toilet paper holder and making it more susceptible to splashes from toilet users when they cough or sneeze, or water when washing their hands or cleaning; 2. When the paper is cut after being pulled out, the cover tends to lift up, so it must be held down with the hand opposite the one holding the paper, increasing the risk of infection with the novel coronavirus or norovirus; The present invention has been made to solve the above-mentioned problems associated with conventional roll paper cutters, and has as its first object to provide a roll paper cutter that can cover the leading edge of the cut paper, making it less susceptible to splashes or water, and that allows the paper to be easily pulled out even in this state, and secondly, to provide a roll paper cutter that can cut the pulled out paper with one hand. [Means for solving the problem]

[0005] In order to achieve the first object described above, the invention described in claim 1 is a roll paper cutter for cutting a required length of paper pulled out from a roll paper rotatably held in a paper holder, the cutter body having a cutting blade formed on one edge, an attachment part for attaching the cutter body to a cover of the paper holder, and a hinge part for connecting the attachment part to the cutter body so as to be freely swingable. a stopper provided on the attachment portion or the cutter body to regulate a swing angle of the cutter body; When the attachment part is attached to the cover, the cutter body extends downward from the edge of the cover so as to cover the leading end of the roll paper, and a gap is formed between the surface of the roll paper and the cutting blade part so that a fingertip can be inserted. The stopper is formed on the surface of the attachment portion or the cutter body by standing up from the folded state. It is composed. As described in claim 2, the stopper different from the stopper may be configured to stand up in conjunction with the swinging motion of the cutter body. Claim 3 As described above, the vertical width of the cutter body may be determined to be a dimension that allows the leading edge of the roll paper cut by the cutting blade to peel off from the surface of the roll paper and hang down.

[0006] With this configuration, after a predetermined length of paper has been pulled out from the roll paper, the cutting blade of the cutter body cuts the paper, and the leading edge of the cut roll paper is hidden behind the cutter body, making it less likely to get splashed or wet. Also, there is a gap between the cutter body and the roll paper that allows the user to insert a finger into the gap and easily grab the leading edge of the roll paper. Also, by providing a stopper that regulates the swing angle of the cutter body, cutting of paper becomes easier. Furthermore, by configuring the stopper to be formed by standing up from a folded state on the attachment part or the surface of the cutter body, or by configuring it to stand up in conjunction with the swinging movement of the cutter body, the stopper can be stored in approximately the same plane as the cutter body and the attachment part, making the roll paper cutter thinner. For example, even if it is distributed on the street as a novelty item, it will not be bulky, and it will not be an obstacle for the recipient to carry it. AlsoBy setting the vertical width of the cutter body to a dimension that allows the tip of the roll paper cut by the cutting blade to peel off from the surface of the roll paper and hang down under its own weight, the tip of the roll paper is always peeled off from the surface of the roll paper and hangs down on the back side of the cutter body, and the tip can be easily picked up with one hand even if the tip of the roll paper is not visible. moreover By forming the cutter body and the attachment part from cardboard or a thin plastic plate, the roll paper cutter can be made thin and small, so that it does not take up much space and is not an obstacle for the recipient to carry even when distributed as a novelty item on the street, at an event venue, in a company, or at a business establishment, for example. Therefore, the cutter body By printing company or store advertisements or educational slogans such as "no drinking and driving," "wearing a mask," and "hand disinfection" on the surface, it is possible to achieve publicity, advertising, and educational effects.

[0007] As described in claim 4, an adhesive tape attached to the cutter body can be used as the hinge portion, and as described in claim 5, a part of the adhesive tape may constitute the attachment portion. By doing so, the roll paper cutter can be made even thinner and more compact.

[0010] In order to achieve the second objective above, the following claims are made: 6 The invention described in is configured such that the angle of swing of the cutter body caused by the stopper is determined so that the center of rotation of the roll paper is located on an extension of the cutter body abutting against the stopper. With this stopper configuration, the cover does not lift up when cutting paper, allowing the paper to be cut with one hand. Effect of the Invention

[0011] According to the present invention, the leading end of the roll paper is hidden behind the cutter body after cutting, making it less likely to be splashed by coughs or sneezes from toilet users, or splashed with water when washing hands or cleaning. In addition, the leading end of the cut roll paper is peeled off from the surface of the roll paper and positioned between the roll paper and the cutter body in a dangling state, making it easy to grab and pull out the leading end. Furthermore, by providing a stopper, the paper can be pulled out with one hand and then cut with the other hand, reducing the chance of touching the cover and lowering the risk of infection with the novel coronavirus, norovirus, and the like. BEST MODE FOR CARRYING OUT THEINVENTION

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the roll paper cutter of the present invention will be described in detail with reference to the drawings. [First embodiment] Figure 1 relates to a first embodiment of the roll paper cutter of the present invention, (a) being a front view, and (b) being a side view showing the swinging state. Figure 2 is an oblique view explaining how to attach the roll paper cutter to the cover of a paper holder, (a) showing the state before attachment and (b) showing the state after attachment. Figure 3(a) is a side view of the paper holder with the roll paper cutter attached, and (b) is a side view of the paper holder explaining how paper is pulled out from the roll paper. As shown in the figure, the roll paper cutter 1 of the present invention has a flat cutter body 11 formed in a rectangular shape, an attachment part 12 that is attached to a cover 21 of a paper holder 2 such as a toilet paper holder, and a hinge tape 13 as a hinge part that connects the cutter body 11 to the attachment part 12 so that it can swing freely in the direction of symbol I in Figure 1(b).

[0013] [Cutter body 11] The cutter body 11 is formed in a rectangular shape from cardboard, a plastic plate, or the like. The width of the cutter body 11 (the width in the left-right direction on the paper in FIG. 1(a)) is formed to be slightly smaller than the width of the cover of a paper holder such as a toilet paper holder, and a cutting blade 11c for cutting paper pulled out from a roll of paper is formed on one edge of the cutter body 11. The shape of the cutting blade 11c is not particularly limited as long as it can cut paper, and it may be cutting blade 11c composed of multiple equally spaced consecutive triangular peaks as in the illustrated example, or it may be cutting blade 11c in the shape of a knife edge. The vertical width of the cutter body 11 (the vertical width of the paper in FIG. 1(a)) is dimensioned so that after a predetermined length of paper is pulled out from the roll paper 22 and cut, the tip of the roll paper 22 is hidden behind the cutter body 11. The thickness of the cutter body 11 is preferably as thin as possible so that the cutter body 11 does not easily bend or deform when cutting the paper pulled out from the roll paper 22.

[0014] The horizontal dimension of the cutter body 11 can be approximately 10 cm to 12 cm for use with, for example, a toilet paper holder 2. The vertical dimension of the cutter body 11 can be approximately 4 cm to 6 cm, but it is preferable that the leading edge 22a of the roll paper 22 cut by the cutting blade 11c is a dimension that allows it to peel off from the surface of the roll paper and hang down under its own weight, as shown in Figure 3(a). In this way, even if the leading edge 22a of the roll paper 22 is not visible, the leading edge 22a can be easily picked up with one hand and the roll paper 22 can be pulled out. The larger the vertical width dimension, the larger the distance w (see Figure 3(a)) between the surface of the roll paper 22 and the tip 22a, which reduces the likelihood of your hands touching the surface of the roll paper 22 when picking up the tip 22a and pulling out the roll paper 22, has the advantage of reducing the risk of infection. However, since the roll paper cutter 1 becomes larger as the vertical width dimension increases, it is best to set the upper limit at approximately 10 cm. Furthermore, the thickness of the cutter body 11 is approximately 1 mm when the cutter body 11 is made of cardboard or plastic plate. The surface 11a of the cutter body 11 is a part that is easily noticeable to users who use the restroom, for example. By displaying advertisements for companies and stores as well as educational slogans such as "No drinking and driving" and "Masks and hand disinfection" on this surface 11a, it is possible to attract customers to companies and stores, discourage drunk driving, and take measures against infectious diseases.

[0015] [Attachment part 12] The attachment part 12 is for attaching the cutter body 11 to the cover 21 of the paper holder 2. In the illustrated example, the attachment part 12 is formed from a rectangular flat plate having a width equal to or smaller than that of the cutter body 11, and the material thereof can be the same as that of the cutter body 11. As long as the cutter body 11 can be attached to the cover 21 of the paper holder 2, the shape and material of the attachment part 12 are not particularly limited. For example, when a thin hinge tape 13 serving as a hinge part described later is formed from an adhesive tape, a part of this hinge tape 13 may be directly configured as the attachment part 12. It is preferable to make the vertical width of the attachment part 12 as small as possible within a range that still maintains sufficient strength of attachment to the paper holder 2. In this way, the cutter body 11 and the attachment part 12 can be made into a flat plate that is not bulky for users to carry, and can be made into a size suitable for distribution as a novelty item on the street, at event venues, companies, offices, etc. The thickness of the attachment part 12 may be the same as or smaller than the thickness of the cutter body 11. As shown in Fig. 3, a gap S is formed between the cutter body 11 and the roll paper 22 so that the user can insert their finger, and the size of this gap S can be adjusted by adjusting the thickness. In addition, various known means can be used to attach the attachment portion 12 to the cover 21. For example, a magnet can be used for the stainless steel cover 21, or an adhesive surface 12a made of adhesive tape or the like can be provided on the back surface of the attachment portion 12, as in the example shown in the figure.

[0016] [Hinge Tape 13] The hinge tape 13 used should have flexibility to allow the cutter body 11 to swing freely relative to the attachment part 12 while connecting the cutter body 11 and the attachment part 12, and should have a certain degree of restorability to return the cutter body 11, which has risen when cutting paper, to its original position after cutting. As such hinge tape 13, commercially available adhesive tapes made of resin can be mainly used. A part of the hinge tape 13 may be configured as the attachment portion 12, and before use, a covering sticker is affixed to the adhesive surface of the hinge tape 13 (the part indicated by the symbol 12a in the illustrated example), and when attaching it to the cover 21 of the paper holder 2, this covering sticker is peeled off to expose the adhesive surface.

[0017] [Attaching to cover 21] To attach the roll paper cutter 1 configured as above to the cover 21 of the paper holder 2, the covering sticker on the back surface of the attachment part 2 is peeled off to expose the adhesive surface 12a. The adhesive surface 12a is then attached to an appropriate position on the cover 21, so that a gap S is formed between the surface of the roll paper 22 and the cutting blade 11c formed at the bottom end of the cutter body 11, allowing the user to insert the tip of their finger. Since the cover 21 generally has a curved shape that conforms to the surface of the roll paper 22, this curvature may be utilized to form the gap S. In this case, the larger the gap S, the less effective it is at shielding the roll paper cutter 1 from water and splashes, so it is preferable to make it as small as possible within the range where the tip of a user's finger can be inserted. When the curvature of the cover 1 cannot be utilized, or when the degree of curvature is insufficient and it is difficult to form a gap S into which the tip of the user's finger can be inserted, the thickness of the attachment part 2 is reduced or an auxiliary member is inserted into the underside of the cutter body 11, thereby ensuring a gap S of appropriate dimensions.

[0018] With the roll paper cutter 1 configured as described above, as shown in FIG. 3, by attaching the roll paper cutter 1 to the cover 21, the end 22a of the roll paper 22 is hidden behind the cutter body 11, preventing splashes of water and droplets caused by the user coughing, sneezing, etc. from adhering to the roll paper 22. Meanwhile, because an appropriate gap S is formed between the end 22a of the roll paper 22 and the cutter body 11 so that the user can insert a fingertip, the user can insert a fingertip F into the gap S to push up the cutter body 11 and easily pick up the end 22a of the roll paper 22. Then, after pulling out a predetermined length of paper from the roll paper 22, the user can use the cutting blade 11c of the cutter body 11 to cut the predetermined length of paper from the roll paper 22.

[0019] [Second embodiment] In the roll paper cutter 1 of the first embodiment described above, when cutting paper that has been pulled out by a predetermined length from the roll paper 22, it is necessary to restrict the swinging motion of the cutter body 11 with the other hand. Therefore, in the second embodiment of the roll paper cutter 1, a stopper 15 is provided on either the cutter body 11 or the attachment member 12, and the stopper 15 regulates the cutter body 11 so that it does not swing more than a predetermined angle, making it possible to cut paper pulled out to a predetermined length from the roll paper 22 with one hand. Figure 4 shows a second embodiment of the roll paper cutter 1, where (a) is an oblique view of the roll paper cutter 1 showing the state before the stopper 15 is raised, (b) is an oblique view of the roll paper cutter 1 showing the state after the stopper 15 has been raised, (c) is an oblique view explaining the function of the stopper 15 when the roll paper cutter 1 is attached to the cover 21, and Figure 5 is a side view explaining the function of the stopper 15 and the appropriate swing angle.

[0020] [Stopper 15] In this embodiment, the stopper 15 is formed in a rectangular shape that can be folded in three at creases 15a and 15b, and one end (the upper end in the illustrated example) is fixed to the attachment part 12. The attachment part 12 and the stopper 15 may be formed integrally. The other end of the stopper 15 is a free end that is not fixed, and creases 15a and 15b are formed at two separated points along the way. Therefore, before the stopper 15 is raised, the stopper 15 is in close contact with the surfaces of the cutter body 11 and the attachment part 12, and the roll paper cutter 1 maintains its flatness as a single sheet. When attaching the roll paper cutter 1 to the cover 21, the stopper 15 is raised by folding the stopper 15 in the same direction at the creases 15a and 15b so that the stopper 15 has a triangular shape when viewed from the side (see FIG. 5). In addition, for example, an adhesive portion can be formed on the other end side of stopper 15 so that when the other end side is folded at crease 15b, the adhesive portion can fix the other end side to attachment portion 12, thereby allowing the triangular shape of the upright stopper 15 to be maintained. With this stopper 15, when a predetermined length of paper pulled out from the roll paper 22 is cut by the cutting blade portion 11c of the cutter body 11, the swinging motion of the cutter body 11 can be regulated by the stopper 15, and the paper can be cut with the same hand that holds the paper when pulling it out. If the extension line II of the cutter body 11 is located above the center of rotation C of the roll paper 22, the cover 21 will tend to slip off the surface of the roll paper 22 and float up around the hinge 23, making it necessary to hold down the cover 21 with the other hand. On the other hand, if the extension line II is located at the same level as the center of rotation C of the roll paper 22 or slightly below the center of rotation C, the cover 21 will be pressed down against the surface of the roll paper 22, preventing the cover 21 from floating up. Therefore, it is advisable to set the swing angle of the cutter body 11 so that the extension line II is positioned at the same position as the rotation center C of the roll paper 22 or slightly below it.

[0021] [Another embodiment of the stopper 15] FIG. 6 shows another embodiment of the stopper 15, and is a partially enlarged side view of the boundary between the attachment portion 12 and the cutter body 11. In FIG. In this embodiment, the attachment portion 12 and the cutter body 11 are connected by a flat stopper 15. A V-groove 15d is formed on the surface of the flat stopper 15 at the boundary between the attachment portion 12 and the cutter body 11, and the cutter body 11 can be swung freely relative to the attachment portion 12 with the V-groove 15d as a fulcrum. When the cutter body 11 is swung relative to the attachment portion 12, the width of the V-groove 15d gradually narrows, and eventually the opposite sides of the V-groove 15d come into close contact with each other, restricting the swung motion of the cutter body 11. The maximum swing angle of the cutter body 11 is determined by the apex angle of the V-groove 15d. The apex angle of the V-groove 15d should be set so that the extension line II is located at the same level as or below the center of rotation C of the roll paper 22, as shown in FIG. 5.

[0022] [Still another embodiment of the stopper 15] FIG. 7 shows still another embodiment of the stopper 15, and is a partially enlarged side view of the boundary between the attachment portion 12 and the cutter body 11. In FIG. The stopper 15 in this embodiment is formed by connecting four flat plate-like members (151 to 154), one of which, member 151, is fixed to the surface of the attachment portion 12, and member 152 adjacent to member 151 is fixed to the surface 11a of the cutter body 11 by adhesion or the like. Therefore, in this embodiment, the stopper 15 functions as a hinge portion. In addition, the members 151 to 154 are formed as folds, and when the cutter body 11 is swung relative to the attachment portion 12, the members 153 and 154 begin to stand up as shown in (b), (c), and (d) from the flat state shown in Fig. 7(a), and when the member 153 abuts against the surface 11a of the cutter body 11, the stopper 15 is completed in a triangular shape in side view, the same as the stopper 15 in Fig. 5. This restricts the swinging of the cutter body 11.

[0023] Although the preferred embodiments of the present invention have been described, the present invention is not limited to the above-mentioned embodiments. For example, while stopper 15 is fixed to the surface of attachment portion 12 in FIG. 4, it may be fixed to surface 11a of cover body 11. [Industrial Applicability]

[0024] The present invention can be widely applied to paper holders that hold roll paper 22, and can be applied not only to toilet paper holders but also to other paper holders that hold roll paper 22, such as kitchen paper holders. [Brief description of the drawings]
