Description

[Technical Field]

[0001] The present invention relates to a holder that grips the leading edge of roll paper such as toilet paper or kitchen paper at the opening, pulls it out, and cuts it to the required length. [Background technology]

[0002] Roll paper holders require different core rods for coreless and coreless rolls. Furthermore, when pulling out roll paper, such as toilet paper or kitchen paper, the tip of the paper sticks to the roll, making it difficult to grasp. Therefore, users have to use their fingertips or both hands to peel or crease the paper, making it easier to pull out. While some holders allow users to stop the rotation of the roll and cut it with one hand, few holders allow users to easily grip the paper after cutting it. Instead, users rotate the exposed roll paper by hand, causing the tip to hang down, making it easier to grip. In this case, a large portion of the roll paper is exposed, which can be touched repeatedly and easily collects dust, creating hygiene issues. While there are inventions that allow users to easily grip the roll paper with one hand and then pull and cut it to the required length, the mechanisms are complicated.

[0004] When pulling out roll paper, the tip of the paper you are pulling out sticks to the paper it is wrapped around, making it difficult to grasp and pull out. Also, holders that require both hands to pull out and cut the required length, or holders with a lot of exposed roll paper, create hygiene issues, such as repeatedly touching the exposed paper with your hands and making it prone to collecting dust.

[0005] Many roll paper holders use a core rod to load the roll paper, but since only roll paper that matches the shape of the core rod can be used, it is necessary to choose between matching it to the roll paper or to the holder's core rod, and a holder that can be used regardless of whether the roll paper has a core is desired. Also, there are many opportunities in daily life to use materials other than rolled paper, and when pulling the material out of the holder, the tip of the material sticks to the opening, making it difficult to pull out. [Means for solving the problem]

[0006] To provide a dust-resistant and hygienic roll paper holder that can be used with one hand and that is dust-resistant, in which roll paper is stored in a paper chamber formed of a pressure plate, side plates and a bottom tray, which has the function of pulling out the roll paper to a required length, stopping its rotation and cutting the paper at the same time, and when pulling out the roll paper, only the gripping part of the paper is taken out of the paper chamber, and when the roll paper is pulled out, the paper is gripped with one hand, pulled out and pulled upward so that the blade of the cutter part catches the roll paper, and the push rod of the pressure plate stops the rotation of the roll paper and it is cut by the blade of the cutter part equipped on the pressure plate.

[0007] The holder with the paper chamber does not require a core rod and can be loaded by simply placing the roll paper in the paper chamber regardless of whether the roll paper has a core material or not, and when loading, the tip of the paper glued to the paper wound around the roll paper is peeled off and passed over the paper receiving roller, which is sandwiched between the roll paper in the paper chamber and the paper gripping margin, so that the gripping margin is always kept floating above the holder and the roll paper during loading. [Effects of the Invention]

[0008] The pressure plate provided in the roll paper holder described in claim 1 is attached to one rotating shaft by a hinge, so that when one side is raised the other side moves down like a seesaw, hooking the paper onto the blade of the cutter and pulling it up to cut it, while at the same time the push rod presses the roll paper in the paper chamber to stop the rotation of the roll paper, allowing the paper to be cut with one hand. Furthermore, the stronger the pulling force on the paper hooked onto the blade of the cutter, the stronger the force of the push rod pressing the paper and stopping the rotation of the roll paper, making it possible to cut even thick, difficult-to-cut paper.

[0009] When the cored roll paper is used up and there is no more paper to be pulled out, the push rod on the pressure plate pushes the core material, allowing it to be removed from between the two upper and lower paper receiving rollers on the front of the holder described in claim 1. However, if there is paper remaining, the roll paper comes into contact with the lower paper receiving roller and rotates, preventing the roll paper from being lifted. When the paper runs out, the rotation stops, and the core material is lifted by pulling out the paper. Further pulling out the paper tears the paper and separates the core material, which then falls down between the two upper and lower paper receiving rollers, allowing the core material to be removed. In the case of coreless roll paper, the push rod on the pressure plate presses down on the remaining core portion (the center portion glued at the beginning of winding during manufacturing) to prevent it from being lifted, helping the roll paper to rotate. By pulling out the paper, the roll paper is used up, and the core that can no longer rotate can be removed by passing it over the paper receiving rollers.

[0010] The push rod provided on the presser plate described in claim 2 acts as a weight when the handle of the presser plate is pulled and the presser plate is raised to open the paper chamber, and the push rod acts as a weight, causing the center of gravity of the presser plate to move outward, facing away from the paper chamber, with the rotation axis of the paper receiving roller as the boundary. The rotation axis of the hinge of the cutter part provided on the presser plate is extended outward from the side plates on both sides of the paper chamber, and both ends act as stoppers for the presser plate. The presser plate rotates, and the rotation is stopped by these stoppers, causing the presser plate to rise and maintain the paper chamber open, making it easier to load the roll paper. When the presser plate is lowered to close the paper chamber, the center of gravity of the presser plate moves toward the paper chamber, and the push rod presses against the roll paper, stopping it from rotating inadvertently. This prevents the roll paper from rotating too much when pulled out and being pulled out too far, and prevents the roll paper from rotating in the opposite direction and causing the tip of the paper to return to the paper chamber. The grip is always outside the paper chamber, making it easy to pull out the paper, and when cutting paper with the presser plate, it can be done with one hand.

[0011] The cutter portion of the pressure plate described in claim 3 has a blade with its tip bent toward the paper chamber, and its base end is attached to the pressure plate by a hinge. After the paper is cut, it hangs down. However, when there is enough paper remaining on the roll and the cutter portion is positioned downwards and the paper grip is difficult to see, simply pressing the hanging cutter portion rotates around the hinge and rises upward, making the paper grip area more visible and easier to grasp. Furthermore, as the roll paper is used and less paper remains, the cutter portion moves upward, making the paper grip area visible without having to press the cutter portion. The hanging cutter portion ensures that the tip of the blade always faces the paper chamber, facing the user, for safe use.

[0012] The holder for the roll paper holder described in claim 4, in which the spacing between the side panels on both sides that form the paper chamber is widened and the width of the bottom tray, pressure plate and top cover is widened, can use wider roll paper, and can be used to line up multiple roll paper horizontally, with each roll separated by a side panel, allowing the top cover above the paper chamber loaded with spare roll paper to be used more widely, and can be reinforced and used as a shelf or armrest, etc.

[0013] The holders with paper chambers described in claims 1 to 4 can be used in the same way as roll paper if the material is rolled up in a material other than paper, such as film or foil. In addition, the box-shaped holder encloses the material, and only the gripping edge is touched when pulling it out, making it a hygienic holder. [Brief explanation of the drawings]

[0015] This invention is intended to be fixed to a wall (vertical surface) or table (horizontal surface) to prevent the paper from being lifted when cutting. However, if it can be fixed using magnets or other means, it can be used as a portable holder. Here, we will explain it as a roll paper holder that is fixed to a wall. The main components that make up the paper chamber (3) of the holder are shown in Figure 1. (A) is a front view of the paper chamber (3), and (C) is a cross-section of the paper chamber (3). A roll of roll paper, with or without a core, is placed on the tray (3) and used as a holder. (B) is a cross-section of the pressure plate (6). The pressure plate (6) is a main component for one-handed use and is equipped with a push rod (8) to stop the rotation of the roll paper and a cutter (7) to cut it to the required length. The paper to be pulled passes between the pressure plate (6) and a cylindrical paper receiving roller (4) inserted into a rotating shaft parallel to the paper roll axis. This ensures that the paper grip is always outside the paper chamber and floating above the paper roll and the holder, even with repeated use. In addition, the roll paper is rotated by the paper receiving rollers 4 and 5, so that even easily torn paper such as toilet paper can be pulled out with little force.

[0016] Figure 2 shows how to load roll paper. When loading roll paper, the top cover 2 is opened, the handle 6a of the pressure plate is pulled, and the pressure plate 6 is raised to open the paper chamber ▲3▼. Figure 3 is an oblique view of this holder, showing the paper chamber in an open state. The hinges 7b of the cutter part of the pressure plate 6 extend outward from the side plates on both sides, and both ends come into contact with the outer edges of the side plates 1, acting as stoppers that stop the rotation of the pressure plate 6. The pressure plate 6 must be raised to keep the paper chamber ▲3▼ open, and the glued tip of the paper from the roll paper withdrawal opening a must be pulled off, and the paper receiving roller 4 must be sandwiched between the tip of the paper and the roll paper in the paper chamber to load the roll paper.

[0017] Figure 4 shows that when first using the roll, there is a lot of paper remaining and cutter part 7 of push plate 6 is positioned downwards, making it difficult to see the paper roll pull-out opening a. However, if cutter part 7 of push plate 6 is pressed, the cutter part will rotate around hinge 7b, causing blade 7a to rise upwards, making the area for gripping paper roll pull-out opening a more visible and easier to grasp, and blade 7a will face the paper chamber side facing away from people, allowing for safe use.

[0018] Figure 5 shows how to remove the remaining core material after the cored roll paper has been used up. Core material b is pulled up when the roll paper is used up, but if the paper breaks without passing between pressure plate 6 and paper receiving roller 4, core material b can be dropped and removed from between paper receiving roller 4 and paper receiving roller 5 (▲1▼). In this case, the width of gap (▲1▼) needs to be larger than the diameter of core material b of the roll paper.

[0019] Figure 6 shows a cored roll of paper loaded into the holder, and when the roll is pulled out, it comes into contact with paper receiving rollers 4 and 5, which rotate, allowing the roll to rotate and not be lifted, allowing the paper to be pulled out easily. Figure 7 shows the state when cutting the cored roll of paper just before it runs out, with cutter part 7 of pressure plate 6 rotating around pressure plate hinge 9 and rising upward, and cutter part 7 hanging down after the paper has been cut.

[0020] Figure 8 is a diagram of a coreless roll paper being loaded, and shows the same movement as the cored roll paper described above. Figure 9 shows the state of the coreless roll paper just before it is used up, with the core part of the roll paper (the central part glued at the beginning of winding during manufacturing) fitted between the paper receiving roller (lower level) 5 and the roll paper receiving tray 3 (▲2▼).The push rod of the pressure plate presses down on the core part of the roll paper that is running low, preventing it from lifting, and helping the core part to rotate.By pulling out the paper, the roll paper can be used up, and the core part that can no longer rotate is removed from the paper chamber by passing it over the paper receiving roller while still glued. [Industrial Applicability]

[0021] This invention is for a roll paper holder, but in the case of toilet paper, if it can be used regardless of whether it has a core or not, and can be loaded with one hand and cut to the required length when used, it will be a holder that can be used by people with hand disabilities. Also, this invention is premised on being fixed to a vertical or horizontal surface, but if it can be fixed to the surface using a magnet or the like, it can be made into a detachable wall-mounted holder, or if a portable box-shaped holder with a modified base that can be placed stably on a flat surface such as a table could be made, the range of uses would be expanded, and it could be used with any rolled material other than paper, such as resin film or foil.
