Description

Technical Field

[0001] The present invention relates to a roll paper holder that can easily cut roll paper such as toilet paper regardless of the rotation direction of the roll paper such as toilet paper to be installed.

Background Art

[0002] Conventional toilet paper holders are configured to simply support a roll of toilet paper (hereinafter sometimes simply abbreviated as "roll paper") rotatably with its axial direction horizontal. Even if there is a cutting part, it is provided at one place in the horizontal direction. In Japan, it is configured on the premise that the end of the roll paper is pulled out from the upper side of the roll (so-called, facing outwards). When installed so that the end of the roll paper is pulled out from the lower side of the roll (so-called, facing inwards), the roll paper is difficult to cut at the cutting part and is difficult to use. For this reason, when replacing the roll paper, there is the trouble of having to check the direction in which the roll paper is pulled out and install it, and when the roll paper is installed in an inconvenient facing-inwards direction that is difficult to use, there is the trouble of having to remove the roll paper and reinstall it in a convenient facing-outwards direction. In particular, the difference in the installation direction of the roll paper is not easily distinguishable visually, and there were cases where users were forced to endure inconvenience without noticing the misinstallation. Furthermore, the operation of cutting the roll paper with one hand is difficult, which is inconvenient for the elderly, disabled, and children.

[0003] Here, Patent Document 1 discloses a vertical toilet paper holder in which a lid is provided at the insertion opening of toilet paper at the head of a box-type toilet paper case that stores a plurality of papers with the core of the toilet paper vertical, a paper core receiving shaft is attached to the lid, a core discharge lid that closes the discharge port of the paper core at the pedestal at the bottom of the toilet paper case in an openable and closable manner and is fixed with a stopper is provided, a paper core receiving shaft is attached to the core discharge lid, an opening is provided at the lower front surface of the toilet paper case, a sliding door is attached to the opening, and paper cutting blades are provided at both side portions of the sliding door. [Prior art documents] [Patent Documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2006-021006 [Overview of the project] [Problems that the invention aims to solve]

[0005] However, the vertical toilet paper holder described in Patent Document 1 stores toilet paper in a box-shaped case with a sliding door, resulting in a large size and weight, and requiring a large installation space. Furthermore, although the cutting direction of the paper can be switched between the front and back sides by operating the sliding door to match the rotation direction of the toilet paper installed inside the box-shaped case, there is the inconvenience and hassle of having to operate the sliding door.

[0006] Therefore, the object of the present invention is to provide a roll paper holder that can easily cut roll paper regardless of the rotation direction of the installed roll paper. [Means for solving the problem]

[0007] The roll paper holder of the invention of claim 1 comprises a pair of clamping members, each having a cutting portion formed at its tip and a pair of clamping portions that clamp the roll paper with its rotation axis in the vertical direction, and arranged facing each other; and an elastic member that rotatably connects the pair of clamping members and biases the pair of clamping portions of the pair of clamping members toward each other.

[0008] The pair of clamping members described above are arranged facing each other, with a pair of clamping portions on one end for holding a roll of paper, and preferably a pair of gripping portions on the other end for being grasped by a person's hand. The pair of clamping parts described above are arranged facing each other and have a cutting portion at each end, and are used to clamp the roll paper with its rotation axis in the vertical direction. As long as they can clamp the outer surface of the roll paper, their shape is not particularly limited, and for example, they may be formed in a curved shape. The cutting section described above is provided vertically along the tip edge of each of the pair of clamping sections and is formed in a sharp shape for cutting roll paper. The pair of gripping parts described above are arranged facing each other and are grasped by a person's hand and pressed in a direction that brings them closer together. As long as they can be grasped and pressed in a direction that brings them closer together, their shape is not particularly limited, and preferably, recesses or protrusions can be provided on the outer surface to make them less likely to slip when grasped.

[0009] The elastic member described above connects a pair of clamping members so that they can rotate relative to each other, forming a fulcrum, and biases the pair of clamping portions of the pair of clamping members toward each other. For example, a torsion spring (torsion coil spring) is used. The above-mentioned roll paper includes paper or non-woven fabric wound into a roll, such as toilet paper, kitchen paper, and paper towels.

[0010] The roll paper holder of claim 2 further comprises a support means for supporting the pair of clamping members. The above-described support means rotatably supports the pair of clamping members, and may be supported, for example, by a shaft passing through the pair of clamping members, or by a joint.

[0011] The roll paper holder of claim 3 further comprises a support shaft portion inserted into the cylinder of the roll paper that is clamped by the pair of clamping portions. The aforementioned support shaft is inserted into the inner cylinder (core hole) of the roll paper and supports the roll paper so that it can rotate.

[0012] The cutting portion of the roll paper holder according to claim 4 has notches formed at its upper and / or lower ends in the vertical direction. The aforementioned notches are provided at one or both ends of the cut section along the vertical direction, i.e., at the upper end and / or lower end, thereby exposing the vertical end of the roll paper. [Effects of the Invention]

[0013] The roll paper holder according to claim 1 comprises a pair of clamping members, each having a cutting portion at its tip and a pair of clamping portions that clamp the roll paper with its rotation axis in a vertical direction, and the clamping members being arranged opposite each other, and an elastic member that rotatably connects the pair of clamping members and biases the pair of clamping portions of the pair of clamping members toward each other, wherein the pair of clamping members are installed to clamp the roll paper with its rotation axis in a vertical direction.

[0014] Therefore, by elastically clamping the roll paper with its rotation axis oriented vertically by a pair of clamping parts and an elastic member, each having a cutting portion at its tip, it is possible to ensure ease of pulling out the roll paper while also providing resistance to the roll paper when it is pulled out and cut, thereby facilitating the cutting of the roll paper. In particular, since the roll paper is elastically clamped by a pair of clamping parts and an elastic member, and each tip of the pair of clamping parts has a cutting portion, the roll paper can be easily cut regardless of the rotation direction of the roll paper elastically clamped by the pair of clamping parts. Furthermore, with a system that elastically clamps the roll paper, even if the roll diameter of the roll paper decreases with use, the roll paper can be held stably, and ease of use can be maintained until the roll paper is completely used up.

[0015] According to the roll paper holder of claim 2, since it further comprises a support means for supporting the pair of clamping members, the support means supports the pair of clamping members, and in addition to the effects described in claim 1, it becomes possible to pull out and cut the roll paper in a stable manner, making it easier to cut the roll paper.

[0016] The roll paper holder of claim 3 further comprises a support shaft inserted into the cylinder of the roll paper held by the pair of clamping parts, thereby suppressing misalignment and eccentricity of the roll paper and enabling smooth and stable rotation of the roll paper. Therefore, in addition to the effects described in claim 1, the operability of pulling out and cutting can be improved, making it easier to cut the roll paper.

[0017] According to the roll paper holder of claim 4, since the cutting portion has notches formed at its upper and / or lower vertical ends, it is easy to grasp the end of the roll paper from the notches. Therefore, in addition to the effects described in claim 1, it is possible to easily pull out the roll paper to be used next time by gripping the end of the roll paper.

Embodiments for Carrying Out the Invention

[0019] [Embodiment] Hereinafter, embodiments of the present invention will be described with reference to Figs. 1 to 5. In an embodiment of the present invention, the toilet paper holder 1 is exemplified as a roll paper holder. The toilet paper holder 1 as a roll paper holder according to an embodiment of the present invention has a pair of sandwiching portions 11A and 11B that are arranged opposite to each other and sandwich a roll-shaped toilet paper R as a roll paper at one end side, and a pair of gripping portions 12A and 12B that are gripped by a person's hand at the other end side. The pair of sandwiching members 10A and 10B, a spring 31 as an elastic member that connects the pair of sandwiching members 10A and 10B to be rotatable relative to each other and biases the pair of sandwiching portions 11A and 11B in a direction approaching each other, and as support means for supporting the pair of sandwiching members 10A and 10B, a support column portion 43 that supports the pair of sandwiching members 10A and 10B and a base portion 41 on which the support column portion 43 stands, and a support shaft portion 45 that stands on the base portion 41 and is inserted into the cylinder of the roll-shaped toilet paper R (hereinafter, may be simply referred to as "roll paper R").

[0020] In this embodiment, a pair of clamping members 10A and 10B are each molded from synthetic resin into a roughly V-shape, and have a pair of roughly arc-shaped clamping portions 11A and 11B at one end for clamping the roll paper R, and a pair of gripping portions 12A and 12B at the other end for being grasped by a person's hand, with a bent portion 13 in the middle. In this embodiment, the height of the pair of clamping members 10A and 10B is formed to be approximately the same as or slightly larger than the width of commercially available toilet paper R (approximately 105 mm to 114 mm) (for example, approximately 100 mm to 130 mm).

[0021] The pair of clamping parts 11A and 11B, which are positioned opposite each other and spaced apart, are formed in a roughly arc-shaped curve so that they can clamp along the outer curved surface of the roll paper R. Specifically, the distance between the pair of clamping parts 11A and 11B that clamp the roll paper R is increased in the direction of separation for a predetermined length from the bent portion 13 toward one end (tip), but thereafter, the distance narrows in the direction of approach toward the tip (cut portion 14) (see Figure 4(a)). The pair of clamping parts 11A and 11B are spaced apart without touching each other at their tips. This makes it possible to hold the roll paper R stably in a compact form that does not take up much space.

[0022] Each clamping portion 11A, 11B has a tip shape that is formed to be approximately sharp, narrowing towards the end, and has a cutting portion 14 that applies tearing force to the roll paper R. This cutting portion 14 has a sharp cutting edge (cut) because its thickness is reduced from the outer circumference to the inner circumference. Furthermore, in this embodiment, since the lower vertical end corner of the cutting section 14 is notched to form a notch 14a, even if the roll paper R is cut along the cut edge of the cutting section 14 and the edge of the roll paper R does not come out from the cut edge of the cutting section 14, the corner of the lower end edge of the roll paper R is exposed at the notch 14a. Therefore, when using it again, the corner of the edge of the roll paper R exposed at the notch 14a can be grasped and pulled out. This makes it easier to take out the roll paper R when using it again.

[0023] On the other hand, the pair of gripping parts 12A and 12B, which are formed at the other end opposite to the pair of clamping parts 11A and 11B and are positioned opposite each other and spaced apart, are spaced apart in the direction from the bent part 13 side toward the other end (base end) side (see Figure 4(a)). The opening between the pair of clamping parts 11A and 11B is such that the other end can be grasped with one hand. In this embodiment, the pair of gripping parts 12A and 12B have their thickness partially reduced on the outer surface of the other end to form a recess (indentation) 16. This makes it easier to grasp the pair of gripping parts 12A and 12B with one hand while maintaining strength, thus improving operability by making them less likely to slip.

[0024] Furthermore, a pair of clamping members 10A and 10B, each formed in a roughly V-shape, are rotatably connected by a spring 31 via a support shaft 35, with the convex sides of their bent portions 13 facing each other (see Figure 4(a)). Specifically, a spring engagement portion 32 for attaching a spring 31 is formed in the bent portion 13 located between the clamping portions 11A, 11B and the gripping portions 12A, 12B. By engaging the spring 31 with the spring engagement portion 32, the spring 31 is attached, and the pair of clamping members 10A, 10B are rotatably connected. In this embodiment, the spring engagement portion 32 is formed in the bent portion 13 of the clamping members 10A, 10B between the clamping portions 11A, 11B that clamp the roll paper R and the gripping portions 12A, 12B that are gripped by a person's hand, and is formed on the inner side (convex side) closer to the gripping portions 12A, 12B.

[0025] More specifically, in this embodiment, multiple torsion springs are used as the spring 31, and multiple spring engagement portions 32 are provided, each formed in an annular or hook shape that the ends of the torsion springs catch on. The springs 31, which are made of torsion springs, are attached by bending the ends and hooking them onto the annular or hook-shaped spring engagement portions 32. At this time, the springs 31, which are made of torsion springs, are attached in an elastically deformed state, and the springs 31, which are made of torsion springs, bias the pair of clamping portions 11A and 11B toward each other (closing direction).

[0026] Thus, in this embodiment, a spring 31 consisting of multiple torsion springs is attached to multiple spring engagement portions 32 formed on the bent portions 13 of a pair of clamping members 10A and 10B, thereby rotatably connecting the pair of clamping members 10A and 10B and forming a fulcrum. That is, the pair of clamping members 10A and 10B are configured to rotate around the spring 31. Furthermore, because the spring 31, which consists of torsion springs, is attached to the spring engagement portions 32 in an elastically deformed state, the spring 31, which consists of torsion springs, biases the pair of clamping portions 11A and 11B toward each other (closing direction).

[0027] In this embodiment, the spring 31, which is a torsion spring that engages with the spring engagement portion 32 and rotatably connects a pair of clamping members 10A and 10B, has a coil-shaped portion. For this reason, the support shaft portion 35 is inserted into the coil (annular) portion. In other words, the spring 31, which rotatably connects a pair of clamping members 10A and 10B, is fitted onto the support shaft portion 35. The support shaft portion 35 is erected on the rear end side of the base portion 41, that is, it is arranged to extend vertically on the rear end side of the base portion 41 and is integrated with the base portion 41. This stabilizes the pivot point where the pair of clamping members 10A and 10B are rotatably connected by the spring 31, preventing rattling of the pair of clamping members 10A and 10B, and stably gripping the roll paper R, making it easier to pull out the roll paper R and to cut it, thus improving usability.

[0028] Thus, in this embodiment, a pair of clamping members 10A and 10B are rotatably connected by a spring 31 made of a torsion spring, and the spring 31 made of a torsion spring forms a fulcrum that rotatably connects the pair of clamping members 10A and 10B. Furthermore, the spring 31 made of a torsion spring that rotatably connects the pair of clamping members 10A and 10B biases the clamping portions 11A and 11B at one end of the pair of clamping members 10A and 10B toward each other. Therefore, the roll paper R can be elastically clamped between the pair of clamping portions 11A and 11B of the pair of clamping members 10A and 10B.

[0029] Furthermore, a pair of clamping members 10A and 10B are provided with holes 17 running through them in the height direction (up and down direction) at the bent portion 13, and a support column 43 erected on the base portion 41 is inserted into these holes 17.

[0030] The base portion 41 consists of a roughly rectangular flat plate made of synthetic resin. When its length is considered as the front-to-back direction, a support shaft portion 35 is erected perpendicular to the upper surface at the rear end (one end in the length direction), two support column portions 43 are erected in front of it, and another support shaft portion 45 is erected perpendicular to the upper surface at the front end (the other end in the length direction). These support shaft portions 35, support column portions 43, and support shaft portion 45 are integrated with the base portion 41 by joining or integral molding.

[0031] The support column 43 consists of a large-diameter flange portion 43a integrated with the base portion 41 and a small-diameter shaft portion 43b integrated with the flange portion 43a. The diameter of the hole 17 formed in the bent portion 13 of the clamping members 10A and 10B is slightly larger than the diameter of the shaft portion 43b and smaller than the diameter of the flange portion 43a (for example, about 10 to 30 mm). In other words, the diameter of the flange portion 43a is larger than the diameter of the hole 17. Therefore, each clamping member 10A and 10B has its shaft portion 43b inserted into the hole 17 formed in the bent portion 13, and its bottom surface faces the upper surface of the flange portion 43a and is positioned away from the upper surface of the base portion 41. That is, the bottom surfaces of the gripping portions 12A and 12B on the bent portion 13 of a pair of clamping members 10A and 10B rest on the upper surface of the flange portion 43a. Thus, the pair of clamping members 10A and 10B are rotatably supported on a support column 43 consisting of a flat base portion 41 and a flange portion 43a and a shaft portion 43b integrated therewith.

[0032] Furthermore, the support shaft portion 45 also consists of a large-diameter flange portion 45a integrated with the base portion 41 and a small-diameter shaft portion 45b formed integrally with the flange portion 45a. The diameter of the shaft portion 45b is smaller than the inner diameter of commercially available roll-shaped toilet paper R (approximately 38mm to 40mm), while the diameter of the flange portion 45a (for example, approximately 50 to 80mm) is larger. Therefore, when the inner cylinder of the roll paper R is inserted into the shaft portion 45b, the bottom surface of the roll paper R in the width direction (perpendicular to the axial direction) is set away from the upper surface of the base portion 41. That is, the bottom surface of the roll paper R in the direction perpendicular to the width direction rests on the upper surface of the flange portion 45a. On the base portion 41, the support shaft portion 45 is located in front of the support columns 43 at an intermediate position between the support columns 43, and is provided between a pair of clamping portions 11A and 11B. From this point onward, the roll paper R, which is held between the clamping portions 11A and 11B of the pair of clamping members 10A and 10B, is rotatably supported on a support shaft portion 45, which consists of a flange portion 45a and a shaft portion 45b.

[0033] Thus, the pair of clamping members 10A and 10B are rotatably supported at their bent portions 13 by the base portion 41 and the support column portion 43 erected thereon, and the roll paper R that is clamped by the clamping portions 11A and 11B of the pair of clamping members 10A and 10B is also rotatably supported by the support shaft portion 45 erected on the base portion 41. In this configuration, the pair of clamping members 10A and 10B are positioned with their bottom surfaces resting on the upper surface of the flange portion 43a, and are separated from the base portion 41 by the vertical height of the flange portion 43a. Similarly, the roll paper R is positioned with its bottom surface perpendicular to its width direction (axial direction) resting on the upper surface of the flange portion 45a, and is separated from the base portion 41 by the vertical height of the flange portion 45a. This reduces the contact area between the pair of clamping members 10A and 10B and the upper surface of the base portion 41 during rotation, thereby preventing damage due to wear. Furthermore, the roll paper R is placed on the flange portion 45a, which has a smaller surface area than the base portion 41, reducing the friction and resistance surfaces during rotation, allowing the roll paper R to be pulled out smoothly.

[0034] Furthermore, the toilet paper holder 1 of this embodiment is equipped with an upper lid portion 50, which is positioned above and opposite to the base portion 41 and attached to the support column portion 43 and the support shaft portion 45. Specifically, circular recesses (not shown) corresponding to the diameters of the shaft portion 43b of the support column 43 and the shaft portion 45b of the support shaft portion 45 are formed on the inner surface of the top cover portion 50. These recesses fit with the shaft portion 43b of the support column 43 and the shaft portion 45b of the support shaft portion 45, thereby attaching the top cover portion 50 to the shaft portion 43b of the support column 43 and the shaft portion 45b of the support shaft portion 45.

[0035] The top cover portion 50 covers the roll paper R, which is held by the pair of clamping members 10A and 10B, thereby preventing dust from adhering to the roll paper R and maintaining hygiene. Furthermore, since the top surface of the roll paper R is not exposed, the design can be improved.

[0036] In the toilet paper holder 1 of this embodiment, when installing (setting) a roll of toilet paper R, the user grasps the pair of gripping parts 12A and 12B formed on the other end sides of the pair of clamping members 10A and 10B with one hand and presses the pair of gripping parts 12A and 12B toward each other. Since the pair of clamping members 10A and 10B are rotatably connected by a spring 31 that acts as a fulcrum, the space between the pair of clamping parts 11A and 11B on one end side of the pair of clamping members 10A and 10B expands against the biasing force of the spring 31 (see Figure 5(a)). Next, after placing the roll of paper R between the expanded pair of clamping parts 11A and 11B, the pressure on the pair of gripping parts 12A and 12B is released. From this point, the biasing force of the spring 31 returns the pair of clamping parts 11A and 11B toward each other, and the roll paper R is elastically clamped (see Figure 5(b)). That is, the roll paper R is elastically clamped by the pair of clamping parts 11A and 11B and the spring 31, which consists of a torsion spring that rotatably connects the pair of clamping members 10A and 10B and forms the fulcrum, with its rotation axis oriented vertically.

[0037] In this embodiment, the toilet paper holder 1 is rotatably supported by the support shaft 45, which is erected on a base portion 41 that is placed on any surface and positioned between a pair of clamping portions 11A and 11B, by passing the inner cylinder of the roll paper R through the support shaft 45 with the rotation axis of the roll paper R oriented vertically.

[0038] Therefore, according to the toilet paper holder 1 of this embodiment, the roll paper is elastically clamped by a pair of clamping parts 11A, 11B and a spring 31 with its rotation axis oriented vertically. When the end of the roll paper R, which is clamped by the pair of clamping parts 11A, 11B with its rotation axis oriented vertically, is pulled out, and after the desired length has been pulled out, the roll paper R is cut with the cutting parts 14 formed at the ends of each of the pair of clamping parts 11A, 11B, resistance is applied to the roll paper R, making it easier to cut. Thus, cutting can be done with one hand, and the ease of operation with one hand makes it easy to use for the elderly, people with disabilities, and children.

[0039] In particular, although the roll paper R is elastically held by a pair of clamping parts 11A, 11B and a spring 31, the roll paper R is held by the pair of clamping parts 11A, 11B with its rotation axis direction vertical, and a cutting part 14 is provided at each end of the pair of clamping parts 11A, 11B. This allows the roll paper R to be cut vertically regardless of its rotation direction, that is, whether it is installed to rotate clockwise or counterclockwise, by pressing the roll paper R against the cutting part 14 of the pair of clamping parts 11A, 11B and folding it back in the opposite direction of rotation. Therefore, cutting the roll paper R is easy without requiring complex operations, regardless of the rotation direction of the roll paper R, while ensuring ease of pulling out the roll paper R. Furthermore, because the roll paper R is easy to cut, it is less likely to tear irregularly when cut.

[0040] In other words, when replacing the roll paper R, it can be used with ease regardless of the direction in which the roll paper R is installed or whether it is rotated, and regardless of the dominant hand, without having to check the orientation of the roll paper R when replacing it, thus eliminating the hassle of having to consider the installation orientation of the roll paper R when replacing it. In particular, since the cutting portion 14 is formed at the tip of each of the pair of clamping portions 11A and 11B of the pair of clamping members 10A and 10B, it is possible to recognize by sight that the installation orientation of the roll paper R does not need to be considered, and the direction of operation is also easy to recognize visually, enabling the operation of pulling out and cutting the roll paper R without having to be particularly conscious of the operation method. In addition, when setting the roll paper R, the spring's repulsive force makes it easy to operate when gripping the pair of gripping parts 12A and 12B and pressing them toward each other. Visually, it is also easy to recognize that gripping the pair of gripping parts 12A and 12B and pressing them toward each other expands the clamping parts 11A and 11B, allowing the roll paper R to be placed between them. Therefore, it is suitable for implementation in public restrooms. Furthermore, in a system that elastically holds the roll paper R, even if the roll diameter of the roll paper R decreases with use, the roll paper R can be held stably, and the roll paper R held by the pair of clamping parts 11A and 11B will be pressed firmly against the cutting part 14, thus maintaining the ease of use of the pulling and cutting operations until the roll paper R is completely used up.

[0041] Furthermore, the toilet paper holder 1 of this embodiment elastically holds the vertically positioned roll paper R using a pair of clamping parts 11A, 11B of a pair of clamping members 10A, 10B and a spring 31, and cuts the roll paper R vertically with a cutting part 14 formed at the tip of the pair of clamping parts 11A, 11B. This reduces the horizontal installation space required, making it compact. Therefore, it offers greater flexibility in installation and can be used in a wide range of environments, from homes to public restrooms. Also, since the cutting part 14 is provided on the member that holds the roll paper R, the number of parts can be reduced. Therefore, the structure is not complex, making it less prone to breakage, easy to assemble, and cost-effective. Moreover, it can be made lighter and easier to mass-produce. In addition, since the roll paper R is elastically held vertically, the surface extending vertically is wide and the surface extending horizontally is small, so dust and dirt are less likely to accumulate, making it easy to maintain hygiene and providing excellent hygiene.

[0042] Furthermore, the configuration in which the roll paper R is elastically held by a pair of clamping parts 11A, 11B and a spring 31 prevents the roll paper R from being pulled out unexpectedly, making it easier to maintain hygiene. In addition, according to the toilet paper holder 1 of this embodiment, a support column 43 erected on the base 41 passes through a hole 17 that penetrates vertically in the bent portion 13 of a pair of clamping members 10A and 10B, and the pair of clamping members 10A and 10B are supported by the base 41 and the support column 43. Therefore, the toilet paper holder 1 can be installed simply by placing the base 41, on which the pair of clamping members 10A and 10B are supported, on a horizontal surface. At this time, it does not take up horizontal space, so it can be installed even in narrow spaces. Also, because the pair of clamping members 10A and 10B are supported by the support column 43, stable operation of pulling out and cutting the roll paper R is possible.

[0043] As described above, the toilet paper holder 1 as a roll paper holder in the above embodiment comprises a pair of clamping members 10A, 10B arranged opposite each other, each having a cutting portion 14 at its tip and a pair of clamping portions 11A, 11B that clamp a roll of toilet paper R with its rotation axis in the vertical direction, and a pair of gripping portions 12A, 12B that are grasped by a person's hand, and a spring 31 made of a torsion spring as an elastic member that rotatably connects the pair of clamping members 10A, 10B and biases the pair of clamping portions 11A, 11B of the pair of clamping members 10A, 10B toward each other.

[0044] Therefore, according to the toilet paper holder 1 as a roll paper holder of the above embodiment, the roll paper R is elastically clamped with its rotation axis in the vertical direction by a pair of clamping parts 11A, 11B each having a cutting part 14 at their tip and a spring 31. This ensures that the roll paper R is easy to pull out regardless of the direction of rotation of the roll paper R, and provides resistance to the roll paper R when it is pulled out and cut, that is, provides sufficient tearing force, making it easy to cut the roll paper R. Furthermore, since the roll paper R is elastically clamped by a pair of clamping parts 11A, 11B, and each of the pair of clamping parts 11A, 11B has a cutting part 14 at its tip, it is possible to easily cut the roll paper R regardless of the direction of rotation of the roll paper R that is elastically clamped by the pair of clamping parts 11A, 11B. Furthermore, with elastic clamping of the roll paper, even if the roll diameter of the roll paper decreases with use, the roll paper can be held stably, and ease of use is maintained until the roll paper is completely used up.

[0045] According to the toilet paper holder 1 as a roll paper holder of the above embodiment, it further comprises a base portion 41 as a support means for supporting a pair of clamping members 10A and 10B, and a support column portion 43 provided so as to extend vertically from the base portion 41. As the pair of clamping members 10A and 10B are supported by the base portion 41 and the support column portion 43, stable operation of pulling out and cutting the roll paper R is possible, and cutting the roll paper R becomes easier.

[0046] The toilet paper holder 1 as a roll paper holder of the above embodiment further includes a support shaft portion 45 that is inserted into the cylinder of the roll paper R held by a pair of clamping portions 11A and 11B, thereby preventing eccentricity in the rotation of the roll paper R and stabilizing its rotation. Therefore, the operability of pulling out and cutting the roll paper R is improved, and cutting the roll paper R becomes easier.

[0047] According to the toilet paper holder 1 as a roll paper holder of the above embodiment, the cutting portion 14 has a notch 14a formed at its lower vertical end, making it easy to grasp the end of the roll paper R from the notch 14a. Therefore, by being able to grasp the end of the roll paper R and pull it out, it is easy to pull out the roll paper R for the next use. That is, even if the cut end (tip) of the roll paper R gets caught (turns back) inside the cut of the cutting portion 14, it is possible to easily find the end of the roll paper R from the notch 14a and pull it out.

[0048] Furthermore, when implementing the present invention, the notch 14a of the cutting portion 14 is not limited to being formed at its lower vertical end, but may also be formed at its upper vertical end, or the notch 14a may be formed at both ends of the upper and lower ends. In particular, if the notch 14a is formed at the upper and / or lower ends, the roll paper R will be less likely to tear when pulled out, and the roll paper R will be easier to cut.

[0049] Furthermore, according to the toilet paper holder 1 as a roll paper holder of the above embodiment, a pair of gripping members 10A, 10B have a pair of gripping parts 12A, 12B formed on the opposite end side from the pair of clamping parts 11A, 11B, which are gripped by a person's hand. The pair of gripping parts 12A, 12B are also rotatably connected by a spring 31 made of a torsion spring as an elastic member. By gripping the pair of gripping parts 12A, 12B with one hand and pressing them in the direction of approach, the pair of clamping parts 11A, 11B can be expanded. Therefore, while gripping and pressing the pair of gripping parts 12A, 12B with one hand, the core of the roll paper R can be removed after the roll paper R has been used up, or the roll paper R can be placed and replenished between the pair of clamping parts 11A, 11B, making the operation of replacing the roll paper R easier.

[0050] Incidentally, when implementing the present invention, the support shaft portion 45 may be extended vertically upwards so that a replacement (spare) roll of paper R, into which the support shaft portion 45 is inserted, can be stored on top of the roll of paper R held by the pair of clamping portions 11A and 11B. This ensures that even if the roll of paper R is used up during use, it can be immediately replaced with a spare roll of paper R, providing peace of mind.

[0051] In implementing the present invention, the configuration, components, formulation, manufacturing method, etc., of other parts of the roll paper holder are not limited to the embodiments described above. [Explanation of symbols]
