Summary of the Invention

Problems to be Solved by the Invention

[0004] The portion of the holding band that presses the front side of the documents such as a passbook is easily damaged when it comes into contact with the paper of the documents or the hands of the operator. In addition, since the adhesive is applied to a part of the end of the holding band, the holding band needs to apply the adhesive accurately at a predetermined position. Further, since the holding band is temporarily fixed to the mount by the adhesive attached only to the end, the area of that part is small and the temporary fixing is likely to peel off. Also, because there is a fold line, after folding once, it has to be flattened and fixed to the mount, making the temporary fixing even more likely to peel off, and the manufacturing process is also complicated.

[0005] An object of the present invention is to provide a pressing tool that can be easily folded at a predetermined position to easily form a three-dimensional shape and has improved resistance to damage caused by rubbing during use. Another object is to provide a pressing tool temporarily fixed to a mount.

Means for Solving the Problems

[0006] The present invention provides a presser for holding down a stack of papers, wherein a sheet body cut to a predetermined shape is folded to form a three-dimensional shape, and the presser for holding down a stack of papers is provided, wherein the sheet body has a folded portion and an adhesive material placed on its back surface, the folded portion is divided into a first surface that faces the stack of papers and a second surface that has a larger area than the first surface, the sheet body can be folded at the folded portion and the back surface of the first surface is fixed to the back surface of the second surface by the adhesive material, thereby forming a single-layer portion and a double-layer portion, the single-layer portion has a fixing portion that is fixed to the bottom sheet of paper in the stack of papers, and the sheet body, in the folded state at the folded portion, can be bent with the first surface facing the stack of papers so that the fixing portion faces the bottom sheet of paper, and the fixing portion is fixed to the bottom sheet of paper by the adhesive material, thereby maintaining the three-dimensional shape while holding down the stack of papers. [Effects of the Invention]

[0007] The pressing device of the present invention is easily bendable at a predetermined position to form a three-dimensional shape, has improved resistance to damage from friction during use, and can be temporarily fixed to a backing board. [Brief explanation of the drawing]

[0008] [Figure 1] Figure 1 illustrates an example of how to use the clamping tool. [Figure 2] Figure 2 illustrates the first example of a retaining device. [Figure 3] Figure 3 illustrates a second example of a retaining device. [Modes for carrying out the invention]

[0009] An embodiment of the retaining device will be described below with reference to Figures 1 to 3.

[0010] Figure 1 illustrates an example of the use of a binder. Notebook 24 is made by stacking multiple sheets of paper of a predetermined size and binding them together at one side, the binding section 25. To prevent the sheets from falling apart, notebook 24 is secured at the binding section 25 with glue, thread, or the like. Notebook 24 can be opened to separate the stack of papers into two. For example, the right side of the opened notebook 24 can be called paper stack 2. The first side 5 of the opened notebook 24 does not have the papers fixed. The binder 1 covers and holds down the corner of the first side 5 that is prone to falling apart. Paper stack 2 consists of multiple sheets of paper stacked together, including the top sheet 3, which is placed at the top, and the bottom sheet 4, which is placed at the bottom. Paper stack 2 has four sides, including the first side 5 and the second side 6. For example, paper stack 2 may be a notebook or book with one side bound together with glue, thread, tape, etc., or it may be a stack of unbound papers. For example, a stack of paper can be held down using multiple fasteners 1.

[0011] Notebook 24 can be prone to rubbing and bending at the bottom right corner of the top sheet 3 when a right-handed person uses a writing instrument, due to contact with the arm or sleeve. The retainer 1 can prevent bending and rubbing of the paper corners and can also be used as a marker for the desired page. The first fixing part 10 and the second fixing part 11 of the retainer 1 are fixed to the bottom sheet 4 of the paper stack 2 by an adhesive. The corners of the remaining sheets are inserted into the retainer 1, which is configured in a ring-shaped three-dimensional form. The retainer 1 fixes the first fixing part 10 and the second fixing part 11 to the back cover of Notebook 24, forming a ring-shaped section including the top retainer part 7. By inserting the corners of the sheets from the page being used onward into this ring-shaped section, the corners of the paper stack can be held down. The retainer 1 and the bottom sheet 4 form a ring-shaped body, which can be said to be wrapped around the corners of the paper stack.

[0012] The presser 1 covers the corners of the paper stack 2 with an upper presser 7 facing the top sheet 3 that makes up the surface of the paper stack 2, a first side presser 8 facing the first side 5, a second side presser 9 facing the second side 6, and two fixing parts facing the bottom sheet 4 that makes up the back surface, namely the first fixing part 10 and the second fixing part 11. The presser 1 holds down the paper while maintaining its three-dimensional shape by folding the sheet and fixing it to the paper. By holding down the corners, damage to the corners of the paper, including the top sheet 3, is reduced or prevented. The corners can also be described as the area near the corners of the paper stack 2, and may not include the corners themselves.

[0013] The first fixing part 10 and the second fixing part 11 of the presser 1 cover the corner of the bottom sheet 4 of the paper stack 2 and secure it with adhesive, the first side pressing part 8 and the second side pressing part 9 cover the sides of the corner of the paper stack 2, and the top pressing part 7 covers the corner of the top sheet 3 of the paper stack 2. Furthermore, when the first fixing part 10 and the second fixing part 11 are fixed to the bottom sheet 4, they may or may not overlap.

[0014] The first side presser portion 8 and the first fixing portion 10 are separated by the first boundary fold portion 12. By folding at this portion, the first fixing portion 10 can be positioned to face the bottommost sheet 4, and the first side presser portion 8 can be positioned to face the first side 5, thereby forming a three-dimensional shape. The first side presser portion 8 and the top presser portion 7 are separated by the first fold line 14. By folding at this portion, the first side presser portion 8 can be positioned to face the first side 5, and the top presser portion 7 can be positioned to face the topmost sheet 3, thereby forming a three-dimensional shape.

[0015] The second side pressing portion 9 and the second fixing portion 11 are separated by the second boundary fold portion 13. By folding at this portion, the second fixing portion 11 can be positioned to face the bottom sheet 4, and the second side pressing portion 9 can be positioned to face the second side 6, thereby forming a three-dimensional shape. The second side pressing portion 9 and the top pressing portion 7 are separated by the second fold line 15. By folding at this portion, the second side pressing portion 9 can be positioned to face the second side 6, and the top pressing portion 7 can be positioned to face the top sheet 3, thereby forming a three-dimensional shape.

[0016] The first folded portion 16 separates the front and back of the top pressing portion 7. The top pressing portion 7 is folded back at this portion, and the adhesive is not exposed on the back side of the top pressing portion 7. The first folded portion 16 can also be called the folded-back portion. The back side of the top pressing portion 7 is designed so that the adhesive does not adhere to the top sheet of paper 3.

[0017] Figure 2 illustrates a first example of a presser foot. The sheet body 27, which is cut into a predetermined shape and constitutes the presser foot 1, has an adhesive on its back surface and is temporarily fixed to the backing paper 26 by the adhesive. That is, the sheet body 27 is detachably fixed to the backing paper 26. It is preferable that the adhesive is provided on the entire back surface of the sheet body 27 so that it can be stably fixed to the backing paper 26. It can also be said that the sheet body 27 has an adhesive layer formed on its back side. The backing paper 26 is release paper, which can stably maintain the adhesive performance of the adhesive on the back surface of the presser foot 1 and can also easily peel off the presser foot 1. One or more sheet bodies 27 may be temporarily fixed to the backing paper 26.

[0018] The presser foot 1 is removed from the backing paper 26 for use. The removed sheet body 27 can be folded back at the folded portion, i.e., the first bent portion 16, so that the back surfaces face each other, and the back surfaces can be fixed together with adhesive. The sheet body 27 can consist of a double portion and a single portion. The back surface of the single portion of the sheet body 27 has the adhesive material exposed. The single portion becomes the first fixing portion 10 and the second fixing portion 11. The double portion increases the strength of the presser foot 1 and improves its durability.

[0019] The first covering part 17 is on the back side of the upper surface pressing part 7. The second covering part 18 is on the back side of the first side pressing part 8. The third covering part 19 is on the back side of the second side pressing part 9. The first covering part 17, the second covering part 18, and the third covering part 19 can be said to be a covering that covers a part of the adhesive on the back surface of the pressing tool 1, and can also be said to be the first surface facing the paper bundle divided by the first bending part 16. The remaining part can also be said to be the second surface on the back side of the first surface divided by the first bending part 16.

[0020] The first boundary bending part 12 and the second boundary bending part 13 are the boundaries between the single-layer part where the adhesive is exposed and the double-layer part where the adhesive is not exposed, and they divide them. The first boundary bending part 12 and the second boundary bending part 13 can also be said to be bending parts for making the fixing parts 10 and 11 inside the sheet body 27 face the bottom sheet. The sheet body 27 can form a three-dimensional shape in which other parts of the sheet body 25 can face the side surface and the front surface of the paper bundle by bending and fixing the first fixing part 10 and the second fixing part 11 to the back surface side of the paper bundle 2 (see FIG. 1) with the adhesive. The sheet body 27 can form a three-dimensional shape and maintain that state. The first boundary bending part 12 and the second boundary bending part 13 can be arranged in the double-layer part and bent. In that case, the thickness is more than that of the single-layer part, and the bending part is difficult to break.

[0021] It is preferable to accurately fold back the sheet body 27 at the first bending part 16. Therefore, the first bending part 16 is composed of a weak part with a lower strength than the adjacent parts. For example, intermittent cuts are arranged linearly at the first bending part 16. At that time, it is preferable that the end part of the first bending part 16, that is, the edge part of the sheet body 27, is cut. By cutting the end part, the end part becomes free, and it becomes easy to determine the folding direction of the sheet body 27. When the end part is connected, it is necessary to fold that part, and it becomes difficult to fold at the desired position. Other examples of the weak part include making a crease or crushing the sheet body 27.

[0022] The first folding line 14, the second folding line 15, the third folding line 20, and the fourth folding line 21 are weak portions with lower strength compared to adjacent portions. Such weak portions are, for example, linear intermittent cuts. The end portions, that is, the edge portions of the sheet body 27, may be either cut or connected. Or, the weak portion may be a portion that is crushed to reduce its strength. When the sheet body 27 is folded back at the first folding portion 16, the first folding line 14 and the third folding line 20 overlap, and the second folding line 15 and the fourth folding line 21 overlap. The portion where the first folding line 14 and the third folding line 20 overlap and the portion where the second folding line 15 and the fourth folding line 21 overlap constitute the folding portion of the sheet body 27 in the state of being folded back at the first folding portion 16. In the case where the weak portion is an intermittent cut, it is preferable that the first folding line 14 and the third folding line 20 are arranged such that when one is a cut, the other corresponds to an uncut portion so that the cuts do not overlap. Thereby, a through portion can be eliminated in the double portion, and a sudden change in the strength of the sheet can be prevented. The sheet body 27 becomes easier to fold when folded. The same applies to the second folding line 15 and the fourth folding line 21 as the relationship between the first folding line 14 and the third folding line 20. Also, it is preferable that the ends of the first folding line 14, the second folding line 15, the third folding line 20, and the fourth folding line 21 are not cut, whereby the ends of the folding portion can be made difficult to break.

[0023] The first corner portion 22 is an arc-shaped corner of the first fixing portion 10. The second corner portion 23 is an arc-shaped corner of the second fixing portion 11. By making the corners arc-shaped, it can be made difficult to catch on other things when fixed to the bottom sheet.

[0024] The sheet body 27 is folded back at the first folding portion 16 and fixed by an adhesive, forming a single portion and a double portion. Further, by folding the sheet body 27 at the second folding portion and the third folding portion, a three-dimensional shape is formed for the sheet body 27. This three-dimensional shape is the same as the shape of the presser 1 illustrated in FIG. 1. This second folding portion is the first boundary folding portion 12 and the second boundary folding portion 13, and the third folding portion is the portion where the first folding line 14 and the third folding line 20 overlap and the portion where the second folding line 15 and the fourth folding line 21 overlap.

[0025] Figure 3 illustrates a second example of the fastener. One example is a fixing part that secures to the bottom sheet of paper. The sheet body 27 can be folded at the folded portion, i.e., the first folded portion 16, and the back surfaces are fixed together with adhesive to form a single layer and a double layer. The boundary between the single layer and the double layer is marked by the first boundary folded portion 12. The first boundary folded portion 12 divides the sheet body 27 into a part that faces the bottom sheet of paper in the stack and a part that faces the side of the stack. The sheet body 27, folded at the first folded portion 16, can be folded at the first boundary folded portion 12 to position the first fixing part 10 facing the bottom sheet of paper and secure it. Furthermore, the first covering portion 17 is positioned to face the top sheet of paper in the stack and cover the top sheet. By folding along the fifth fold line 28 and the sixth fold line 30, the side fixing part 29 can be positioned opposite the second side pressing part 9 and secured with the adhesive on the back, and the top fixing part 31 can be positioned opposite the top pressing part 7 and secured with the adhesive on the back. The sheet body 27 can fix the first fixing part 10 to the bottom sheet of paper, maintain a three-dimensional shape that covers the corners of the paper stack, and can hold down the corners of the paper stack. The folded and bent parts are made of weak material, making it easy to fold and fold them. [Explanation of Symbols]
