Paper roll holder

Abstract

To provide a paper holder that makes it possible to cut / replace paper using one hand without touching anything other than the paper.SOLUTION: A paper holder includes a paper cutting plate 20 loadable on an arm part, where when the paper cutting plate is pivotally supported in front of a roll of paper A, paper can be cut via leverage using even one hand. A control unit 22 is separated from a cutting unit 24, which inhibits paper from being torn off at an unintended position and enables appropriate cutting. In the case that a top lid 10 is installed, the roll of paper A can be directly operated through an opening composed of a top lid opening and a paper cutting plate opening, utilization is possible without touching anything other than paper. In addition, when a paper cutting plate rotation shaft 23 is made to be pivotally supported at a movable groove 44 and paper is lifted, the paper cutting plate 20 is lifted and, after cutting, falls with force that makes paper hang down, which enables serial use. The paper holder solves various problems.SELECTED DRAWING: Figure 9

Description

[Technical Field]

[0001] The present invention relates to a paper roll holder, and more particularly to a new structure of a contactless, hygienic paper roll holder that allows paper to be cut and replaced as needed with only one hand without touching the roll. [Background technology]

[0002] Paper holders are often used in bathrooms and kitchens as toilet paper holders or kitchen paper holders to hold and cut rolls of paper. Roll paper can refer to toilet paper, kitchen paper, kitchen towels, cooking paper, etc. A typical paper towel holder requires repeated use, often at least once or multiple times, of the following steps: lift the lid with one hand, find the scrap of paper, pick up the paper, and tear it off while holding the lid down with the other hand. Some paper towel holders lack a lid, paper cutting plate, or cutting section. Others require the user to tear along the perforations in the roll or forcefully tear the paper. This typically requires both hands, and the process of tearing the paper increases with each use. In any case, touching a paper towel holder that has been touched by others should be avoided as much as possible, as it can lead to contamination and viral and bacterial contamination. With the COVID-19 pandemic and other outbreaks, being able to tear and use the paper you need without touching the holder is desirable. This is particularly important for toilet paper holders, as it is common for people to wash their hands after using the toilet and toilet paper holder. Kitchen paper holders also require similar precautions since they handle food.

[0003] Roll paper is often attached to an arm installed inside the paper roll holder, and the core of the roll can be pushed up from the bottom of the paper roll holder to the arm. When replacing the roll paper using the above method, the used core falls out and falls to the bottom, but the lid remains up, so it is necessary to manually replace the lid. There are also paper roll holders that use a core rod to install the roll of paper, and in order to remove or install it, you have to use both hands: lift the lid, remove the core and core rod, pull out the core, install a new roll of paper, put the core rod back in, and lower the lid. The above drawbacks arise because conventional paper roll holders are of the type in which a single curved paper cutting plate covers the upper rear of the roll of paper.

[0004] On the other hand, roll paper also comes in a wide variety of materials, qualities, hardness, thickness, single or double, with or without a core or perforations, highly absorbent paper, colored or flavored paper, large rolls, widths, with letters, patterns, pictures or cartoons, and roll paper that does not meet JIS standards.With countless types available on the market to suit consumer needs, it is questionable whether traditional paper roll holders can accommodate them all.

[0005] In recent years, paper roll holders that advertise one-hand cutting have become increasingly popular. These holders have a cutting section and a "weight" on one end of the lid, allowing the paper to be cut with one hand. However, with conventional one-hand cut paper roll holders, cutting requires the action of pulling the paper upward. However, when a force greater than the weight of the paper cutter is applied, the paper cutter plate rises, weakening the cutting force as the paper cutter plate moves, making it impossible to cut the paper. Another problem was that when the roll of paper becomes small, the cutting point shifts, making it impossible to cut the paper. Ultimately, to cut the paper, it was necessary, as with conventional paper roll holders, to hold the lid with one hand and cut with the other.

[0006] For this reason, there is a paper roll holder (Patent Document 1) that has an opening in part of the paper cutting plate, but even if you press the roll paper with your finger over the opening, the part you press with your finger and the part of the paper cutting plate that cuts the paper are different, and even if you press with your finger on the cutter part of the paper cutting plate, the cutting force does not increase, so in many cases the paper cannot be cut by that alone.

[0007] There are also paper roll holders that attach weights to the paper cutting plate to adjust the pressure and make it easier to cut paper (Patent Document 2). However, in this case, the weight only slightly reduces the paper cutting force, while the movement of the paper cutting plate is not prevented, so the effect is minimal. Also, when pulling out the roll of paper, the cutting part always hits the roll of paper, causing it to be cut in an undesired position or making a rattling noise, making it difficult to pull out the paper smoothly.

[0008] There is also a paper roll holder (Patent Document 3) that positions the rotation axis of the cover in front of the roll paper and has a mechanism that secures the roll paper with a part of the cover behind the rotation axis when the roll paper is cut. Even looking at the detailed explanation and diagrams in Patent Document 3, nothing is clear other than that the rotation axis of the cover is positioned in front of the roll paper, and there are questions about the location, method, structure, and rationale for installation. The same applies to the mechanism that secures the roll paper with a part of the cover, and there are many questions about that as well.

[0009] There is also a paper holder (Patent Document 4) that has a cutter blade for cutting paper at the bottom end of the front panel of the outer box, an opening for withdrawing paper between the front end of the bottom panel of the outer box and the front panel, and an inclined section that supports the rolled paper placed inside the outer box so that it is constantly pressed against the contact section on the front panel.However, this is designed so that the weight of the rolled paper is constantly pressing against the contact section on the front panel due to the inclined section, but the weight of the rolled paper is not that heavy, so the force generated by the inclination is even weaker.Furthermore, when cutting paper, the force acts on the rolled paper in the direction opposite to the front panel, so there is almost no friction between the front panel and the rolled paper.

[0010] There are other prior documents about paper roll holders that claim to be operable with one hand, but in reality, there are none that can be operated without touching the paper roll at all.

[0011] Many commercially available paper roll holders are made of opaque materials, and even when opened, there are blind spots and the contents are hidden, making it impossible to see the position of the torn paper roll, the amount remaining, whether it is wet, dirty, or damaged.In addition, the entire contents of the paper roll holder are unclear, and it is not possible to see if there are foreign objects or insects inside the holder, making it impossible to use the holder safely. [Prior art documents] [Patent documents]

[0012] [Patent Document 1] Japanese Patent Application Publication No. 2019-188097 [Patent Document 2] Japanese Patent Application Laid-Open No. 2004-121691 [Patent Document 3] Japanese Patent Application Laid-Open No. 2003-174981 [Patent Document 4] Japanese Utility Model Application Publication No. 63-181389 Summary of the Invention [Problem to be solved by the invention]

[0013] There are paper roll holders that claim to allow one-handed cutting, but with the conventional structure mentioned above, it is necessary to use skill to operate them so that the paper cutting plate does not rise, and with repeated use, the cutting point between the paper cutting plate and the roll paper gradually drops, making it difficult to apply force to hold down the roll paper, making it difficult to cut the paper all the way with just one hand. Another problem is that, because the cutting section is located on the roll paper, depending on the roll paper, the paper may be cut in an unintended place.

[0014] After the paper is cut, the scraps often rewind into the roll due to shape memory and tensile stress, and each time this happens, the user has to "grab the lid with one hand, lift it up while searching for the scraps of paper, remove the paper with the other hand, lower the lid and hold it down while tearing off the paper," which increases the time and number of contacts and is unsanitary.

[0015] Some paper roll holders do not have lids or cutting sections, and some rolls of paper are difficult to cut or tend to stick to the cutting section. In some cases, compatibility between the paper roll holder and the roll of paper, as well as the installation location and usage environment, is also important.

[0016] When replacing the roll of paper, there are some types of paper roll holders in which the roll of paper is stored inside the holder using a core rod, some that are attached directly to a mounting part on the inside of the holder, and some that have one side inserted into a lever or core rod.However, except for those that do not have a lid or cutting part, it is difficult to easily remove and replace the paper roll with just one hand without touching the holder.

[0017] Paper roll holders are made of opaque materials such as metal, non-ferrous metal, plastic, and wood, making it impossible to see the roll paper or the contents inside the holder directly. This means it is impossible to check the position of the torn paper roll, the amount remaining, whether it is wet, dirty, or damaged. In addition, foreign objects or insects may be mixed into the paper roll holder, and depending on the installation location, it is used by an unspecified number of people. The fact that the entire contents of the paper roll holder are unclear raises concerns about its use from a hygienic standpoint. [Means for solving the problem]

[0018] It has been found that the following paper roll solves the problem. Invention 1, The paper cutting plate (20) that can be placed on the arm portion (46) is pivotally supported by the side portion (40) so that it is in front of the roll paper (A), A paper roll (1) characterized in that the roll paper (A) and the cut portion (24) are not in contact with each other. Invention 2, The paper roll holder (1) of invention 1 is characterized in that the paper cutting plate (20) is pivotally supported by a movable groove (44). Invention 3, A paper cigarette holder (1) according to either invention 1 or invention 2, characterized in that it has an upper cover (10). Invention 4, A paper roll holder (1) according to any one of inventions 1 to 3, characterized in that it has an opening (D) for increasing the exposure of the roll paper (A). Invention 5, A paper roll holder (1) according to any one of Inventions 1 to 4, made of a transparent or translucent material.

[0019] The paper roll holder (1) of the present invention is composed of a paper cutting plate (20) and a side portion (40), and may optionally be equipped with a top cover (10) or an attachment portion (30), as described below. In this application, the front of the paper roll (A) refers to the portion of the paper roll (A) forward of the center, and the portion where the paper cutting plate (20) contacts the paper roll (A) is referred to as the control portion (22).

[0020] In the present invention, the paper cutting plate (20) can be placed on the arm portion (46), so that the control portion (22) exists until the roll paper (A) is used up, thereby achieving the function of the present invention. In addition, the paper cutting plate (20) is supported by the side portion (40) so that it is in front of the roll paper (A), and when the paper is pulled up from under the paper cutting plate (20), the cutting portion (24) rises around the paper cutting plate rotation axis (23), and the control portion (22) controls the roll paper (A) by lever action, allowing the paper to be cut with one hand without having to hold down the paper cutting plate (20). If the paper cutting plate (20) cannot be placed on the arm portion (46), and the amount of roll paper (A) falls below a certain level, the control portion (22) that comes into contact with the roll paper (A) may no longer function.

[0021] Conventionally, the paper cutting plate is supported on a shaft at the upper rear of the roll of paper. After lifting the paper cutting plate, the user would remove the paper and, while pressing the paper cutting plate or cutting section against the roll, tear and cut the paper with the other hand. Even with paper rolls that boast one-handed cutting, the cutting section can sometimes hit the paper when winding it up, causing the paper to tear in an unintended place, or the cut paper can rewind back beyond the paper cutting plate or cutting section, requiring the user to lift the paper cutting plate and search for the edge of the paper or touch it the next time they use it. These factors stem from the fact that the cutting section also doubles as the control section, and the need to hold down the paper cutting plate in order to control and cut the roll of paper presents an issue. Therefore, in this invention, by supporting the paper cutting plate (20) in front of the roll paper (A) as described above, the paper cutting plate (20) is endowed with the function of controlling the roll paper (A) by utilizing the leverage generated when the paper is pulled up. As a result, the paper cutting plate (20) is equipped with a control unit (22) and a cutting unit (24), and by separating the functions into control and cutting, the roll paper (A) and the cutting unit (24) do not come into contact except when cutting. As a result, when pulling out the paper, the cutting unit no longer comes into contact with the roll paper and tears it in an unintended place, and by letting the cut paper hang from the control position, the rewinding effect is blocked, solving the above problem and resulting in a paper roll holder (1) that can be used with one hand without touching anything other than the paper.

[0022] Furthermore, if the paper cutting board (20) is pivotally supported by the movable groove (44), the function of the present invention can be further enhanced. In this invention, because the lever action is used to cut the paper, depending on the type of roll paper, paper may stick to the cutting section (24). To solve this problem, a movable groove (44) is installed that allows the paper cutting plate rotation shaft (23) to move. When the paper is pulled up during cutting, the paper cutting plate (20) rises, and when the cutting is complete, it falls. This momentum has the effect of peeling off paper that has stuck to the cutting section (24). Furthermore, if a paper guide (42) is installed near the bottom of the cutting section (24) to prevent the peeled paper from being rewound onto the roll paper (A) and to hold it in place, one end of the paper peeled by the mechanism will rest on the paper guide (42) and the other end will hang down at an angle, making it easier to grasp the paper after cutting, so it is a good idea to install one as needed.

[0023] In the present invention, the conventional paper cutting plate is divided into two pieces: the top cover (10) and the paper cutting plate (20). The top cover (10) is preferably installed to reinforce the paper roll holder (1), act as a storage space, and protect against splashes and dirt from the roll paper (A).

[0024] Furthermore, by providing an opening (D) in the paper roll holder (1) to increase exposure to the roll paper (A), it becomes possible to operate the roll paper (A) directly through the opening (D) without touching the paper roll holder (1). When the top cover (10) is installed, the top cover opening (12) and the paper cutting plate (20) have a paper cutting plate opening (21). By installing these side-by-side, the roll paper (A) can be more easily exposed. By providing opening (D), it is possible to obtain a paper roll holder (1) that does not require contact with anything other than the paper, and all operations from removing the paper, cutting it, and replacing it can be performed with just one hand.

[0025] The paper roll holder (1) can be manufactured by injection molding or by cutting. It can be made of a transparent or translucent material, and the remaining amount and condition of the paper roll can be seen at a glance, which has the effect of making the paper roll holder safe to use, as well as in terms of management.

[0026] Details of each part are explained below. The top cover (10) will now be described. The top cover (10) is provided with a top cover rotation shaft (11) and a top cover opening (12) as needed. In the present invention, the presence or absence of the top cover (10) may be determined taking into consideration the availability of the opening (D), the purpose, the design, and the shape of the paper cutting board (20).

[0027] The top cover (10) should be installed so that it opens toward the wall, with the top cover rotation shaft (11) supported at the rear upper part of the paper roll (A) like a conventional paper cutting plate. If the top cover (10) is not installed, an opening (D) for the top cover (10) is created, which has the advantage of making it easier to directly handle the paper roll (A) and increasing the degree of freedom in the shape of the paper cutting plate (20). On the other hand, it is effective to install the top cover (10) large to prevent dirt and splashes, but it is recommended to install it carefully so as not to interfere with the mechanism of the paper cutting board (20) described below. The presence of the top cover (10) can also be effective as a way to convey through its shape that the paper cutting board (20) can be used without touching it.

[0028] In the present invention, the conventional paper cutting plates are provided separately as the top cover (10) and the paper cutting plate (20), and by providing a fitting portion (41) on the side portion (40) and by placing the top cover (10) on the upper edge of the side portion (40), it is possible to prevent it from coming into contact with the roll paper (A). As described above, the top cover (10) can be used as a storage space, and by creating the fitting portion (41), the paper roll holder (1) can also be reinforced.

[0029] If a top cover opening (12) is installed in the top cover (10) to expose the paper roll (A), the roll (A) can be handled directly, allowing the paper holder (1) to be used without touching anything other than the paper. Because the top cover opening (12) alone does not expose much of the surface area of ​​the roll (A), installing it in conjunction with the paper cutting plate opening (21), described below, will increase the amount of exposed paper roll (A). This provides protection against infection and contamination, and is also hygienic, as the paper holder (1) can be used without touching areas that have been touched by others.

[0030] There is no particular designation for the shape of the top cover opening (12), and various shapes can be selected, including semicircular, rectangular, heart-shaped in combination with the paper cutting board opening (21), and silhouettes of animals or characters, which are aesthetically pleasing in addition to the convenience mentioned above. In some cases, it is also possible to choose not to provide a top cover opening (12).

[0031] The paper cutting board (20) will now be described. The paper cutting board (20) of the present invention consists of a control unit (22), a paper cutting board rotation axis (23), and a cutting unit (24), and if necessary, a paper cutting board opening (21) may also be installed, which will be described in detail below.

[0032] The shape of the paper cutting board (20) is not particularly specified as long as it can be placed on the arm portion (46) and fits within the side portion (40), and the shape can be selected depending on whether or not the top cover (10) is installed. In this invention, in order to position the paper cutting plate (20) in front of the roll paper (A), a paper cutting plate rotation shaft (23) is provided on the side of the paper cutting plate (20) and is movable by being supported by the side portion (40) and movable groove (44). As a result, when the paper is pulled up, the paper cutting plate (20) rotates around the paper cutting plate rotation shaft (23), and the control unit (22) presses the roll paper (A) with a lever action, clamping and controlling the roll paper (A) between the paper cutting plate (20) and the arm portion (46), allowing it to be cut by the cutting unit (24) located below. All of this can be operated with just one hand, but as mentioned above, the load of the lever action is placed on the paper cutting plate (20), so it is desirable that it be strong enough to withstand this load.

[0033] If the paper cutting plate (20) is also provided with a paper cutting plate opening (21) for exposing the roll paper (A), it may be possible to use the paper holder (1) without touching anything other than the paper. Specifically, since the paper cutting plate (20) is in contact with the roll paper (A), the presence of the paper cutting plate opening (21) allows the roll paper (A) to be directly manipulated without touching the paper cutting plate (20). In this way, the provision of the paper cutting plate opening (21) makes it possible to use the toilet without touching anything other than the paper, even if the paper holder (1) is used multiple times to cut the paper. In addition, when the top cover (10) is installed, a top cover opening (12) is provided, and by arranging it next to the paper cutting board opening (21), a large opening (D) can be secured, and the larger the opening (D), the more effective it is in preventing contact with anything other than the roll paper (A). The shape of the paper cutting plate opening (21) may be V-shaped, U-shaped, rectangular, semicircular, etc., so that the opening (D) can be secured while the paper cutting plate (20) can be placed on the arm portion (46). In addition, the combination of the top cover opening (12) and the paper cutting plate opening (21) can also be used to create an aesthetic appearance for the paper roll holder (1).

[0034] In this invention, the control unit (22) is the part of the paper cutting plate (20) that comes into contact with the roll paper (A), and it is desirable that the arm unit (46) and paper cutting plate (20) can control the paper roll (A) until it is completely used up by contacting the roll paper (A) at a point, a line, or an area. Specifically, resistance can be applied by bending the top of the paper cutting plate (20), processing the surface that comes into contact with the roll paper (A), providing ribs, protrusions, or anti-slip surfaces, or by selecting a combination of these. By placing these on the arm unit (46) within a range that can be controlled even with only the core (C), it is possible to control the paper roll (A) until it is completely used up. When cutting the paper, in addition to the resistance, the roll paper (A) can be clamped between the paper cutting plate (20) and the arm portion (46) using a lever action, allowing for stronger control. This creates tension from the control portion (22) to the edge (B) of the paper being pulled, making it easy to cut with one hand by aligning paper that would break simply by pulling it along the cutting portion (24). However, care must be taken when designing the control portion (22) so that it does not damage the roll paper (A) when it comes into contact with it.

[0035] The paper cutting plate rotation axis (23) is preferably installed horizontally on both sides of the paper cutting plate (20), so that the paper cutting plate (20) can be placed on the arm portion (46) and so that the cutting portion (24) does not protrude from the side portion (40). If the paper cutting plate rotation shaft (23) is shaped like a screw, pin, round bar, or other cylindrical object, the paper cutting plate (20) can move smoothly. By bearing this with the side part (40) or the movable groove (44), the paper cutting plate (20) can be positioned in front of the roll paper (A). Furthermore, due to the shape described above, the paper cutting plate (20) can rotate 360 ​​degrees. Therefore, it is effective to install a stopper (43) on the side part (40) to limit the movement of the paper cutting plate (20), but whether or not to install it can be selected as needed. In this invention, the placement of the paper cutting plate rotation axis (23) is also important. By allowing the paper cutting plate (20) to rest on the arm portion (46) when cutting, it is possible to hold the roll paper (A) all the way to the end. This solves the problem with conventional one-hand cut paper roll holders, where the cutting position shifts as the roll becomes less, making cutting difficult, and creates a mechanism that allows the paper to be cut all the way to the end with just one hand. Furthermore, by placing it closer to the cutting portion (24), a stronger control force can be obtained through the lever action.

[0036] The cutting unit (24) is located on the opposite side of the control unit (22) to cut the paper, and is preferably located in front of the roll paper (A) and wider than the roll paper width. There are no particular specifications for the shape of the cutting portion (24), but care should be taken to ensure that it does not protrude forward from the side portion (40) except when cutting, and the tip of the paper cutting plate (20) can be made sharp-angled, saw-toothed, or uneven, similar to conventional paper roll holders, and it is often advantageous to be able to attach and remove these. Bending the paper cutting plate (20) toward the paper roll (A) positions the cutting point on the paper roll (A) side, making it easier to cut the paper. Suitable materials include plastic, elastomer, silicone, urethane, and synthetic rubber. By making the cutting part (24) thinner, the contact area when cutting paper can be minimized, making it less likely for the paper to stick to it.

[0037] The mounting portion (30) is preferably installed for mounting the paper roll holder (1) and for reinforcement. In the product of the present invention, the paper cutting plate (20) is installed in front of the roll paper (A), so depth (thickness of the mounting portion (30) + diameter of the roll paper + thickness of the paper cutting plate (20)) is required. In order to accommodate various roll paper, it was necessary to use the larger roll paper as a reference and make the side portion (40) protrude. However, since installing the paper roll holder (1) in a narrow space may cause some kind of problem, an opening larger than the width of the roll paper is provided in the mounting portion (30), which has the effect of reducing the protrusion of the side portion (40) by the thickness of the mounting portion (30).

[0038] The side portion (40) will now be described. The side portion (40) of the present invention is provided with a paper cutting plate (20) and an arm portion (46), and if necessary, a top cover (10), an attachment portion (30), a fitting portion (41), a paper guide (42), a stopper (43), a movable groove (44), and a roll set block (45), which are described in detail below.

[0039] Regarding the shape of the side portion (40), the side portion (40) must be deep enough to support the paper cutting plate (20) in front of the roll paper (A), and there are no particular restrictions on the shape as long as the parts and mechanisms described below can be attached and the strength is sufficient for those uses.

[0040] Regarding the fitting portion (41), it is recommended that it be installed to prevent the top cover (10) from coming into contact with the paper roll (A) when installing the top cover (10). Also, since the side portion (40) protrudes, it is recommended that it be installed to reinforce the paper roll holder (1) and to prevent the tip of the side portion (40) from opening too much or closing too much and becoming deformed. Of course, it will still function as long as the top edge of the side portion (40) is not dropped, so whether or not to use a fitting portion can be selected as needed.

[0041] The paper guide (42) is preferably installed on the side section (40) so that it can be positioned near the bottom of the cutting section (24). Whether or not to install it depends on the shape of the paper roll holder, and it can also be installed on both sides of the side section (40). There are no particular restrictions on the shape of the paper guide (42), as long as it does not interfere with the movement of the paper cutting plate (20) or cutting section (24). If the length protrudes from the side section (40) by about 20 to 30 mm, it can be effective in preventing the paper edge (B) from rewinding back into the paper roll (A) after the paper has been cut, depending on factors such as static electricity, shape memory, tensile stress, installation environment, and paper type.

[0042] The stopper (43) is provided on the inside of the side portion (40) to limit the movement of the paper cutting plate (20). Whether or not to provide it is up to the discretion of the user. There is no specific shape for the stopper (43), but it is advisable to install it carefully so that it does not have a sharp shape. By setting the size of the stopper (43) so that the side part (40) can be expanded and the movable range of the paper cutting plate (20) can be released, the cutting part (24) can be easily replaced by rotating the paper cutting plate (20) and turning it upside down. Furthermore, the positional relationship between the paper cutting plate (20), the side portion (40), and the stopper (43) can be determined by taking into consideration whether or not they will affect the mechanism of the paper cutting plate (20).

[0043] The movable groove (44) is a mechanism that supports the paper cutting plate rotation shaft (23) and allows it to move, and is installed opposite the side portion (40) so that the paper cutting plate (20) can be supported in front of the roll paper (A). As a result, when the paper is being cut, the paper cutting plate (20) rises within the movable groove (44) when the paper is lifted, and after the paper is cut, it falls due to gravity, with the force of the drop effective for peeling off any paper that has adhered to the cutting portion (24). This is because, in the present invention, which utilizes a lever effect, the mechanism of the movable groove (44) is effective for peeling off paper when, depending on the type of roll paper, the paper bites into the cutting portion (24) and sticks to it. The mechanism contributes to the non-contact use of the paper roll holder (1) and continuous use with one-handed cutting, and can also be used in conjunction with a paper guide (42) to quickly grasp the end of the paper (B) after cutting.

[0044] On the other hand, pivoting the paper cutting plate (20) at the front upper part of the side part (40) is effective when you want to prevent the protrusion of the front lower part of the side part (40). Also, compared to pivoting the paper cutting plate (20) at the front lower part of the roll paper (A), the control part (22) controls the depth of the roll paper (A), which has the advantage of increasing the distance from the control part (22) to the cutting part (24) and the tensile force transmitted to the paper, resulting in stronger control force. Furthermore, if a paper cutting plate (20) is positioned at the front upper part, gravity is taken into consideration when cutting, and the control section (22) will function by simply pulling it up a little, and the paper can be cut by simply aligning it with the cutting section (24). Furthermore, it is also effective to make full use of the mechanism of the movable groove (44), and it is most effective to set the movable groove (44) in a "N" shape, as will be explained below.

[0045] The "ノ"-shaped movable groove (44) should be installed so that its tip is located at the front upper part of the side part (40), and it should be installed with care so that the paper cutting plate (20) can be placed on the arm part (46) even when the paper cutting plate rotation axis (23) has moved to the tip, and so that the range of the control part (22), the cutting part (24) do not protrude from the side part (40), and the orientation are taken into consideration. In addition, because the paper cutting plate rotation axis (23) can move up to the tip within the "K"-shaped movable groove (44), even if the roll paper (A) is installed incorrectly, the roll paper (A) can pass from bottom to top within the paper roll holder (1), allowing the roll paper (A) to be removed and corrected. Furthermore, since the paper cutting plate (20) is positioned according to the remaining amount of roll paper (A), the cutting portion (24) does not protrude beyond the side portion (40) except when cutting, and the present invention has the advantage that the cutting portion (24) is positioned in front of the roll paper, which can avoid any situations that may cause any inconvenience.

[0046] One of the problems with conventional paper cutting machines is that the paper sometimes rewinds and becomes hidden behind the cutting plate, requiring the user to lift the cutting plate and search for or touch the edge of the paper (B). To solve this problem, we found that in addition to separating the control unit (22) and the cutting unit (24) as described above, using the movable groove (44) to increase the amount of paper that can be pulled out is also effective. Specifically, by exposing the pulled paper to air and stretching it, we cut off the restoring force that would rewind it back onto the roll paper (A). This allows the paper from the control unit (22) to the cutting unit (24) to hang down, making it easier to grip, and thus solving the problem. Furthermore, we found that as the roll of paper (A) becomes smaller, the distance between the roll paper (A) and the cutting unit (24) increases, and when more paper than the diameter of the roll paper (A) is pulled out, the excess paper cannot rewind and hangs down, making it easier to grip.

[0047] After the paper is cut, the paper cutting plate rotation axis (23) falls and hits the bottom of the movable groove (44), generating a collision sound. In order to eliminate this collision sound, an arc is extended at the rear end of the "ノ"-shaped movable groove (44), which allows the arc to deflect the impact and eliminates the collision sound.

[0048] The arm portion (46) is opposed to the side portion (40) or the side portion (40) via the roll set block (45) so as to be able to hold the roll paper (A). As mentioned above, if the paper cutting plate (20) supported on an axis in front of the roll paper (A) can be placed on the arm portion (46), the roll paper (A) can be pinched and controlled between the arm portion (46) by the lever action generated when the paper is pulled up, so it is advisable to install the arm portion (46) so that it does not open or close downward. To enable contactless paper roll replacement, the paper roll holder (1) is pushed up onto the arm (46) to insert the paper roll. However, in this invention, ribs, protrusions, and steps are intentionally placed inside the side portion (40) and the roll set block (45) to allow the arm (46) to fall under its own weight, resulting in a mechanism that can reduce the use of leaf springs and other materials. Care should be taken to ensure that the paper roll does not become blocked. Of course, installing leaf springs or other springs is also effective, and doing so often proves advantageous. It is also effective to adjust the length of the paper cutting plate (20) to create a positional relationship that allows it to be stacked, but in the present invention, in order to prevent the side portion (40) from protruding and to accommodate large rolls of paper, it is preferable to position the arm portion (46) near the center of the mounting portion (30) and the paper cutting plate (20). On the other hand, while a wide arm was common, the large contact surface created resistance, making it difficult to rotate the roll paper and remove the paper. In this invention, the width of the arm (46) is set to approximately 6 to 10 mm, and the contact with the core (C) is narrowed to a point-like shape, reducing resistance and creating "play" to make it easier to rotate the roll paper. This makes it easy to remove the roll paper (A) by operating it directly through the opening (D), and facilitates operation with one hand without touching anything other than the paper.

[0049] The opening (D) varies depending on whether or not a top cover (10) is installed, and the size, shape, and arrangement of the top cover (10) and paper cutting board (20), and refers to the part where the roll paper (A) is exposed. By providing a top cover opening (12) on the top cover (10) and a paper cutting plate opening (21) on the paper cutting plate (20) and combining the two to form a large opening (D), it becomes easier to directly handle the roll paper (A). The opening (D) should be installed for contactless use where only paper is touched, and for one-handed operation, but the installation should also be selected taking into consideration measures against droplets. Furthermore, when installed in combination with the arm portion (46) of the present invention, it has been found to be advantageous in that when the paper end (B) reattaches to the roll paper (A), the paper end (B) can be removed with one finger without touching the paper roll holder (1). Furthermore, the opening (D) can be selected to be installed or not in order to enjoy the shape of the paper roll holder and the pattern of the rolled paper.

[0050] It was found that a paper roll holder (1) with the above-mentioned configuration of each part is the best solution to the problem. The material of the paper roll holder (1) of the present invention can be selected from titanium, stainless steel, aluminum, plastic, wood, glass, etc., and it is also possible to combine multiple materials. Furthermore, if it is made from a transparent or translucent material, the paper roll holder (1) becomes "visible" and the remaining amount of paper roll (A) can be seen at a glance, which is a good option from the perspective of management and aesthetics. [Effects of the Invention]

[0051] The present invention was developed in consideration of the above-mentioned circumstances, and makes it possible to cut and replace the paper to the last with one hand, without touching the paper roll, something that was not possible with conventional paper roll holders.

[0052] When the top cover (10) is installed, a top cover rotation shaft (11) is installed at the rear upper part of the roll paper (A), so that the top cover (10) can be opened and closed freely. When replacing the roll paper, a method has been invented in which the core can be removed by simply pushing up the top cover (10) together with the used core with a new roll paper from the bottom of the paper roll holder (1), and a method has also been invented in which the core can be placed directly on the top cover (10), so that it can be replaced without having to pick it up from the ground. Furthermore, by placing the top cover (10) on the top edge of the side part (40) or by providing a fitting part (41) and setting the top cover (10) flat, it can be used as a storage space when closed. Conventionally, this could only be achieved by adding a shelf afterwards, but it is now possible to propose an integrated type. Furthermore, fitting the top cover (10) and part of the side portion (40) together at the fitting portion (41) also reinforces the paper roll holder (1). Furthermore, by making the paper cutting board (20) into various shapes, a new type of paper towel holder can be proposed for children who dislike using the toilet and for people who want to enjoy design.

[0053] In the present invention, the paper cutting plate (20) is supported on a shaft in front of the roll paper (A), and the control section (22) and cutting section (24) are separate, so that when the paper is lifted, a lever action is activated and the roll paper (A) can be controlled without holding down the lid, and when the paper is pulled out, it does not tear at unintended places as in the past, and a mechanism is obtained that allows appropriate one-handed cutting. In addition, the arm portion (46) is narrower than conventional products and is in almost point contact with the core (C), making it easy to rotate the roll paper (A) and peel off the paper with just one finger.The opening (D) provided in the paper roll holder (1) makes it possible to directly handle the roll paper (A), providing the effect of preventing infection through contactless use where only the paper is touched, and making it easier to use the paper roll holder with one hand.

[0054] For the reasons described above, the paper roll holder (1) of the present invention is effective in maintaining hygienic conditions in toilets, kitchens, etc. as a measure against infectious diseases and contamination. Furthermore, it has an advantage in terms of hygiene, as it allows users to use roll paper without touching a paper roll holder that has been touched by others in public toilets, restaurants, supermarkets, convenience stores, etc., which are frequented by many people. Furthermore, it is highly useful when installed in places where it is necessary to maintain the most hygienic conditions, such as hospitals and nursing homes, where caregivers are needed, or where people who cannot use one hand, or when they can only use one hand, and where it is necessary to be able to easily cut paper as needed with one hand.

[0055] By installing this paper towel dispenser in crowded locations such as hospitals, nursing homes, public facilities, and event venues, it can contribute to reducing congestion and the risk of contact as well as reducing costs by requiring fewer steps than conventional products and incorporating contactless measures. Furthermore, since it can be easily used with one hand, even small children can use the toilet dispenser, and it is also effective for toilet training children, so it can be expected to be highly effective when used at home, in kindergartens, nurseries, daycare centers, elementary schools, and special needs schools.

[0056] By attaching a leaf spring to the arm portion (46), it can be installed vertically, diagonally, or at any angle from 0 to 90 degrees left and right, and if it can be fixed, it can be used for various purposes. For example, the technology can be applied to cutting paper, film, tape, and various other materials, which is expected to improve work efficiency and productivity.By providing a stand, it can be installed anywhere. In addition, there are also rolls of paper that have small cores, such as coreless types, that do not meet JIS standards, and in order to load them, a special core rod must be used, and multiple contacts with the paper roll holder are required to load the roll. However, because the arm section (46) is narrow, it can also accommodate these types of rolls, making it possible to load most rolls of paper.

[0057] This invention can be customized in terms of color, shape, and material, and meets the diverse needs of today's consumers and the requests of customers with strong hygiene concerns.It has created a paper towel holder that is highly convenient and can be handled hygienically through its structure alone.

[0059] The paper roll holder (1) of the present invention has a paper cutting plate (20), a side portion (40), and an arm portion (46), and by installing a top cover (10), an attachment portion (30), and the associated parts as needed, a paper roll holder (1) can be obtained that can be used with only one hand without touching the paper roll holder (1). Below, an embodiment of the present invention will be described based on the drawings. [Example]

[0060] In Example 1, as shown in Figure 1, the paper cutting plate (20) is pivotally supported by the side portion (40) in front of the roll paper (A), and the cutting portion (24) is not in contact with the roll paper (A). A stopper (43) is attached to limit the range of movement of the paper cutting plate (20). In the present application, if the paper cutting plate (20) and the control unit (22) can be placed on the arm unit (46) as shown in Figure 2, it becomes possible to control the roll paper (A) until only the core (C) remains. Also, in the paper roll holder (1) of Example 1, a mechanism is provided in which the arm unit (46) can be attached by attaching a roll set block (45) to the side unit (40), and a step is provided in the side unit (40) so that the arm unit (46) can fall under its own weight. As shown in Figure 3, when the top cover rotation shaft (11) is installed at the rear upper part of the roll paper (A), the top cover (10) can be opened and closed freely, and by fastening the top cover (10) to the side part (40) with the fitting part (41), it does not come into contact with the roll paper (A) and can be used as a storage space, and the box shape also increases its strength. Furthermore, by installing the top cover opening (12) and the paper cutting plate opening (21) together, an opening (D) as shown in Figure 1 is created in the paper roll holder (1), allowing the roll paper (A) to be directly operated, so that the paper roll holder (1) can be used with one hand without touching anything other than the paper. As shown in Figure 4, when the paper cutting plate rotation axis (23) is positioned at the front lower part of the side part (40), the paper cutting plate (20) is supported on the shaft in front of the roll paper (A), allowing it to be cut by lever action. Specifically, when the paper is pulled up, the lower part of the paper cutting plate (20) rises, and the control part (22) controls the roll paper (A), and by aligning the paper with the cutting part (24), the paper roll holder (1) can be cut with only one hand. As can be seen from these diagrams, when assembled using a transparent material, the structure of the paper roll holder (1) and the remaining amount of paper roll (A) can be seen at a glance, making it a "visible" paper roll holder (1) that can be used with confidence. [Example]

[0061] In Example 2, a movable groove (44) as shown in Figure 6 is provided to support the paper cutting plate (20). The movable groove (44) allows the paper cutting plate rotation shaft (23) to move up and down within the groove. In this invention, the paper is cut using a lever action, so the paper is bitten into the cutting section (24) with great force. This can cause the paper to remain attached to the cutting section (24) after cutting, depending on the type of paper. To solve this problem, the movable groove (44) is provided. Specifically, as shown in Figure 7, when the paper cutting plate rotation shaft (23) pulls up the paper, it rises within the movable groove (44), and when the paper is cut, it falls due to gravity, and this momentum has the effect of peeling off the paper attached to the cutting section (24). Furthermore, by installing a paper guide (42) near the bottom of the cutting section (24) as shown in Figure 8, one end of the peeled paper edge (B) rests on the paper guide (42) and the other end hangs down at an angle, making it easy to grab the next time and allowing you to obtain a paper roll holder (1) that does not require you to touch anything other than the paper. [Example]

[0062] In Example 3, a "N"-shaped movable groove (44) was installed at the front upper part of the roll paper (A) as shown in Figure 9. In Example 3, too, the movable groove (44) was provided with an up and down slope so that after the paper is cut, the paper cutting plate rotation shaft (23) or paper cutting plate (20) would fall due to gravity, resulting in the effect of peeling off the paper. In addition, by attaching the cutting section (24) facing downward, the cutting point is moved toward the roll paper, which allows the paper to bite in further forward, making cutting easier.The paper cutting plate rotation axis (23) is located above and in front of the roll paper (A), so the paper cutting plate (20) is placed according to the diameter of the roll paper. Furthermore, the paper cutting plate rotation axis (23) and the paper cutting plate (20) can move within the movable groove (44) to the position shown in Figure 10, so that even large rolls of paper can pass through the paper roll holder (1), which also contributes to preventing the protrusion of the front lower part of the side portion (40). Furthermore, by pulling up the paper, the paper between the control section (22) and the cutting section (24) is taut, and after cutting, the paper tries to rewind due to its shape memory, etc., and the longer the distance, the more air resistance and wrinkles are generated in the paper, making it more difficult to rewind onto the roll paper (A), which has the effect of causing the paper to hang down and become easier to grasp, as shown in Figure 11. Because this does not have a significant impact on use even if the paper guide (42) is not provided, it can be chosen to save materials by eliminating it. When replacing the roll paper (A) with the core (C) still in place, insert the roll paper (A) from bottom to top, and the core (C) will rest on top of the top cover (10) as shown in Figure 12, making it possible to retrieve the core (C) without dropping it, even when replacing it with one hand. [Example]

[0063] In Example 4, a large top cover (10) was installed as shown in Figure 13. The top cover (10) can be opened and closed using a top cover rotation shaft (11), covers the top of the paper roll holder (1), and serves to protect the roll paper (A) from splashes and dirt, and also makes it difficult for the user to press the paper cutting plate (20) directly with their hands, allowing for contactless use. Unlike when the top cover (10) is not installed, the top cover (10) acts as a stopper, which also has the effect of preventing the paper cutting board (20) from accidentally being turned upside down. [Example]

[0064] Example 5 is a paper roll holder (1) in which a movable groove (44) as shown in Figure 14 is installed, which is an extension of the arc of the "ノ"-shaped movable groove (44) of Example 3.The arc prevents the paper cutting plate rotation shaft (23) from colliding with the lower end of the movable groove (44) as it falls after cutting the paper, thereby reducing the sound of the collision. [Example]

[0065] In Example 6, as shown in Figure 15, it is possible to reproduce the present invention even with a molded product, and the roll set block (45) can be built into the side part (40), so that the invention can be carried out without losing functionality even if the number of parts is reduced. [Industrial Applicability]

[0066] In this invention, the paper cutting plate (20) of the paper roll holder serves as one hand, allowing the user to cut and replace the paper with one hand without touching anything other than the paper itself. This is useful as a measure against infectious diseases, especially in public restrooms and restrooms where it is best to avoid touching surfaces that have been touched by others. This is highly useful as a hygiene measure in public restrooms and restrooms used by many people.

[0067] Previously, people who found it difficult to hold down the lid with one hand while cutting paper had to hold the lid down with their head or face, but now they can cut paper hygienically with one hand. This makes it highly useful for a variety of people, situations, and environments, including those hospitalized, visiting, or staying in hospitals or nursing homes, those receiving nursing care, and those who cannot use one hand or who can only use one. Furthermore, while the previous one-hand cut function was limited to single-sheet paper or paper with perforations, it can now be used to cut any type of paper.

[0068] By installing this device in crowded places such as hospitals, nursing homes, public facilities, and event venues, as well as other locations, it requires less operation than conventional devices and provides contactless infection control, which can contribute to reducing congestion and the risk of contact, as well as reducing costs.

[0069] In addition, if the paper roll holder is made of transparent or semi-transparent material, the entire holder can be seen at a glance, allowing managers to directly monitor the remaining amount, leading to improved productivity and efficient work. Users can visually check for insects and the condition of the paper roll, allowing them to use the holder safely and with peace of mind.

[0070] In addition, there are toilet papers that have patterns, designs, cartoons, advertisements, etc. printed on them, and the transparency makes them easier to see and enjoy.

[0071] It can also be installed vertically or diagonally, at any angle from 0 to 90 degrees left or right, making it suitable for a variety of uses in places other than the bathroom or kitchen as long as it can be fixed in place.

[0072] There are no particular specifications for the color, material, or shape of each part of this invention, and as long as the mechanism is maintained, the top cover (10) and paper cutting plate (20) can be designed as desired, making it possible to propose a one-of-a-kind paper roll holder (1) according to customer requests.
