Description

  The present invention relates to a roll paper holder for storing roll paper such as kitchen towels.

Kitchen towels rolled up are widely used in kitchens and living rooms. This kitchen towel is stored in a substantially box-type dispenser attached to a wall surface, and the towel is drawn out and cut at a perforation for use.
In addition, a holder has been developed in which the kitchen towel is placed sideways (the roll axis is in the horizontal direction) and stored in a half-cylindrical container that is split in two, then the container is closed and the container is opened and the kitchen towel is pulled out when in use. (See Patent Document 1).
Furthermore, a stand-type holder has been developed in which a kitchen towel is placed vertically and a towel core is inserted into a shaft upright on a pedestal (see Patent Document 2).

JP 2007-44361 A Japanese Utility Model Publication No. 62-66590

However, the substantially box-type dispenser is heavy and occupies a large space, and there is a problem that it takes time and labor to install the screw on the wall surface.
Moreover, since the holder of patent document 1 has installed the roll sideways in a container, the direction which cuts a towel with a perforation corresponds with the drawing-out direction, and it is difficult to cut unless it presses a roll firmly There is.
On the other hand, in the case of the holder described in Patent Document 1, it is necessary to screw the shaft supporting the towel core to the pedestal, which makes it difficult to attach the kitchen towel. Moreover, it cannot respond to the kitchen towel of various widths, and can only attach the kitchen towel of one kind of width.
That is, an object of the present invention is to provide a roll paper holder in which roll paper such as a kitchen towel is placed vertically to reduce the installation space, the roll paper is easily cut, and the roll paper is easily attached.

In order to solve the above problems, the roll paper holder of the present invention includes a base portion on which one end of the roll paper is placed, and a lower portion that protrudes from the inner surface of the base portion and is inserted into a core on one end side of the roll paper. A side roll paper holding part, a main body part that extends in the axial direction of the roll paper, has one end connected to the base part, and is connected to the other end of the main body part and faces the other end side of the roll paper to a top portion, connected to said top portion extending elastically deformable toward the base portion side, and a upper roll paper holding portion to be inserted into the other end of the winding core of the roll paper, said viewed in the axial direction, the length of the body portion is the roll paper side convexly curved toward the length of the viewed in the axial direction upper roll paper holding unit is the lower roll paper holding unit Ri long, is placed the base portion while facing the axial up and down on the lower side.
With such a configuration, installation space is reduced by placing roll paper such as kitchen towel vertically. In addition, if the roll paper is placed vertically, the drawn paper is pulled downward and cut at the perforation, so the cutting force is concentrated on the top of the paper, and a relatively small force can be obtained simply by placing a hand on the end face of the roll. Can be cut easily and roll paper can be easily cut. Further, the roll paper can be easily attached by simply inserting the roll paper core into the upper roll towel holding portion from the lower side.
Further, the upper roll towel holding part is expanded outward (on the side opposite to the main body part) by the roll paper core, and is bent so as to repel by the elastic force and press the roll paper core toward the main body part side. As a result, since the upper roll towel holding part presses the outer surface of the roll paper against the main body, the roll paper is difficult to rotate when the roll paper is cut at the perforation, and the roll paper is easy to cut without pressing the roll paper.
Further, since the curved portion is in contact with the roll paper, the effect of pressing the roll paper is great, and the roll paper can be reliably pressed by the curved portion even when the roll paper has a small diameter by use.

A length from the tip of the upper roll paper holding portion to the inner surface of the top portion along the axial direction may be ½ or more of the interval between the inner surface of the top portion and the inner surface of the base portion. .
With such a configuration, a roll whose axial length is slightly longer than the interval between the tip of the upper roll towel holding portion and the inner surface of the base portion, from a roll paper having an axial length slightly shorter than the interval between the inner surfaces in the vertical direction of the roll paper holder. Up to paper, roll paper of various axial lengths can be attached with one roll paper holder.

The stress when elastically deforming the tip of the upper roll paper holding part by 30 mm in a direction perpendicular to the axial direction is preferably 1 to 6N.
With such a configuration, the upper roll paper holding portion can be easily bent and the outer surface of the roll paper can be pressed against the main body portion with an appropriate elastic force.

  When the roll paper holder of the present invention is integrally formed with a resin, manufacturing becomes easy and various designs can be adopted.

  According to the present invention, a roll paper holder such as a kitchen towel can be placed vertically to reduce the installation space, and the roll paper can be easily cut and the roll paper can be easily attached.

Hereinafter, embodiments of the present invention will be described.
FIG. 1 shows a perspective view of a roll paper holder 100 according to an embodiment of the present invention. The roll paper holder 100 is formed by integrally molding a resin such as ABS resin, and includes a substantially plate-like base portion 10 and a substantially semi-cylindrical lower roll towel holding portion 15 protruding upward from the inner surface 10a of the base portion 10. A substantially plate-like main body portion 12 extending in the vertical direction and having one end 12a thereof connected to the base portion 10, a substantially trapezoidal top portion 14 connected to the other end 12b of the main body portion 12, and a top portion 14 and a substantially plate-shaped upper roll towel holding portion 16 that is connected to 14 and extends elastically deformable toward the base portion 10 side.
As will be described later, in the present invention, the roll paper holder 100 is stored in the roll paper holder 100 along the axis of the roll paper (vertically) in the direction in which the main body 12 extends (vertical direction). Therefore, the direction in which the main body 12 extends (the vertical direction in FIG. 1) is referred to as the “axial direction of the roll paper”.

Here, the base portion 10 and the top portion 14 are connected so as to protrude horizontally from the same surface side of the main body portion 12, and the base portion 10 and the top portion 14 sandwich the main body portion 12 when viewed from the side surface. It has a U shape (see Fig. 2). Further, the upper roll towel holding part 16 is connected to the side of the top part 14 opposite to the part connected to the main body part 12. Accordingly, when viewed from the side, the main body portion 12 and the upper roll towel holding portion 16 have an inverted J shape with the top portion 14 interposed therebetween (see FIG. 2).
Furthermore, in this embodiment, attachment holes 12h are opened at predetermined positions in the vertical direction of the main body 12, and rubber suction cups 20 are attached to the attachment holes 12h, respectively. And the roll paper holder 100 can be installed by making the suction cup 20 adsorb | suck to vertical surfaces, such as a wall surface, in the state which orient | assigned the longitudinal direction of the main-body part 12 to the up-down direction.

When viewed from the front direction, the main body portion 12 is narrowest at the center portion 12c in the vertical direction. Further, as shown in FIG. 2, when viewed from the side, the main body 12 is curved in a convex shape toward the roll paper side, the vertical center portion 12c is closest to the roll paper, and the end 12a. , 12b away from the roll paper.
The base portion 10 has a shape in which both end portions on the side protruding from the main body portion 12 are rounded, and the lower roll towel holding portion 15 slightly protrudes from the base portion 10 (in this example, the protrusion height L5 (FIG. 2 ) Is about 10 mm).
Further, when viewed from the front direction, the upper roll towel holding portion 16 is formed in a long and slender tongue shape in which the tip 16a is semicircular. Further, as shown in FIG. 2, when viewed from the side, the upper roll towel holding portion 16 is curved toward the central portion 12c of the main body portion 12 while falling in an arc shape bulging outward from the top portion 14, The tip 16a is substantially opposed to the central portion 12c. Furthermore, the tip end 16a is a hollow that swells in a spherical shape toward the main body 12 side, and the tip end 16a can smoothly come into contact with a roll core of a roll paper described later.
In addition, the length (L1 of FIG. 2) of the upper side roll towel holding part 16 is longer than the length L5 of the lower side roll towel holding part 15 along the up-down direction.

FIG. 2 is a side view of the roll paper holder 100. A length L1 from the front end 16a of the upper roll paper holding portion 16 to the inner surface 14a of the top portion 14 is ½ or more of a distance L2 between the inner surface 14a of the top portion 14 and the inner surface 10a of the base portion 10 along the vertical direction. It has become. The reason for this will be described later.
Moreover, the upper side roll towel holding part 16 and the lower side roll towel holding part 15 have a space | interval along the up-down direction. Further, the upper roll towel holding part 16 can be elastically deformed in a direction approaching and separating from the main body part 12 (refer to the left and right direction in FIG. 2 and arrows).

Next, a mode in which the roll paper 200 is housed (attached) in the roll paper holder 100 will be described with reference to FIG.
First, the upper end 200 a of the roll paper 200 is obliquely inserted between the upper roll towel holding unit 16 and the lower roll towel holding unit 15, and the core 200 c of the roll paper 200 is placed on the front end 16 a of the upper roll towel holding unit 16. Insert (FIG. 3A). At this time, the upper roll towel holding part 16 is elastically deformed so as to be separated from the main body part 12 to facilitate the insertion of the roll paper 200 (arrow in FIG. 3A).
As the roll paper 200, either a core roll in which a sheet is wound around a paper tube or a core non-roll in which a sheet is wound to the center without using a paper tube and the center portion is hollow can be used.

Next, the roll paper 200 is moved upward, and the core 200c is inserted up to the base of the upper roll towel holder 16 (until abutting against the inner surface 14a of the top portion 14). At this time, since the length (axial length) L4 of the roll paper 200 in the axial direction is shorter than the interval L2, a gap G is generated between the lower end 200b of the roll paper 200 and the lower roll towel holding portion 15, and the roll paper. 200 can be made vertical (FIG. 3B).
Finally, when the roll paper 200 is pressed downward and the core 200c on the lower end 200b side of the roll paper 200 is inserted into the lower roll towel holding portion 15, the lower end 200b of the roll paper 200 is placed on the inner surface 10a of the base portion 10. (FIG. 3C).
In this way, the roll paper 200 can be stored in the roll paper holder 100 as shown in FIG.

Further, at this time, the upper roll towel holding part 16 is spread outward (on the opposite side to the main body part 12) by the roll core 200c of the roll paper 200, and repels due to the elastic force so that the roll core 200c of the roll paper 200 is moved. It bends so that it may press to the side (arrow of FIG.3 (c)). As a result, the upper roll towel holding part 16 presses the outer surface of the roll paper 200 against the main body part 12, so that when the roll paper 200 is cut at the perforation, the roll paper 200 is difficult to rotate and cut without pressing the roll paper 200. Easy to do. In particular, when the main body portion 12 is bent convexly toward the roll paper side, the curved portion (in this embodiment, the central portion 12c) is in contact with the roll paper 200. Thus, even when the roll paper 200 has a small diameter, the roll paper 200 can be reliably pressed by the curved portion.
In addition, when the tip 16a of the upper roll paper holding part 16 is elastically deformed by 30 mm in the horizontal direction (direction perpendicular to the vertical direction) and the stress is 1 to 6 N, the upper roll paper holding part 16 is easily bent. The outer surface of the roll paper 200 can be pressed against the main body 12 with an appropriate elastic force.

  Further, when the main body 12 is bent convexly toward the roll paper, the curved portion (center portion 12c) is positioned on the front side of the main body 12, so that the center of gravity of the entire main body 12 moves forward. And close to the center of gravity of the base portion 10. As a result, when the roll paper holder 100 is placed vertically with the base portion 10 being self-supporting, the roll paper holder 100 can be stably stood.

  As mentioned above, according to this embodiment, roll paper, such as a kitchen towel, is installed vertically and installation space is reduced. Furthermore, if the roll paper is placed vertically, the drawn paper is pulled downward and cut at the perforation, so the cutting force is concentrated on the top of the paper, and a relatively small force is obtained simply by attaching a hand to the end surface of the roll. Can be cut easily and roll paper can be easily cut. In addition, the roll paper can be easily attached simply by inserting the roll paper core into the upper roll towel holding portion from below.

In the present embodiment, the length L1 is not less than ½ of the interval L2. That is, from the roll paper having an axial length slightly shorter than the interval L2 between the inner surfaces in the vertical direction of the roll paper holder 100, the axial length is slightly longer than the interval L3 between the tip 16a of the upper roll towel holding portion 16 and the inner surface 10a of the base portion 10. Up to long roll paper, roll paper of various axial lengths can be attached with one roll paper holder 100.
For example, when the interval L2 is about 290 mm and L1 is about 170 mm, various roll papers having a commonly used axial length of 9 inches (about 225 mm) to 11 inches (about 275 mm) can be attached.
In FIG. 3C, the tip 16a of the upper roll towel holding portion 16 presses the core 200c of the roll paper 200 toward the main body portion 12, so that the pressing portion is the curved portion of the main body portion 12 (this embodiment). The tip 16a and the curved portion (center portion 12c) may be brought close to each other so as to form the center portion 12c).

FIG. 5 is a bottom view of the roll paper holder 100. In this embodiment, since the semi-cylindrical part of the lower roll towel holding part 15 is directed toward the main body part 12, the semi-cylindrical part is placed along the inner surface of the core 200 c of the roll paper 200, and the roll paper 200 is rotated. Can be made smooth.
As shown in FIG. 6, the lower roll towel holding portion 35 is pivotally supported by the hinge 35 a on the mounting portion 10 t that protrudes from the base portion 10, and the lower roll towel holding portion 35 is possible with respect to the base portion 10. It may be attached in an inverted manner (see arrow in FIG. 6). In this case, when the roll towel holding part 35 is pushed to the main body part 12 side at the lower end of the roll paper 200, the roll towel holding part 35 falls to the main body side, so the lower roll towel holding part 35 is attached to the core 200c of the roll paper 200. It can be inserted easily, and after insertion, it is restored to the state shown in FIG. 6 by the action of a built-in spring and the roll towel is held.

It goes without saying that the present invention is not limited to the above-described embodiments, and extends to various modifications and equivalents included in the spirit and scope of the present invention.
For example, instead of the suction cup 20, a magnet, a hook, or the like may be attached to the main body portion 12, and the main body portion 12 may be fixed to an attachment target on a vertical surface such as a wall surface. Further, a leg or the like may be provided on the lower surface of the base portion 10, and the lower end of the roll paper 200 may be separated from the grounding surface to prevent adhesion of dirt or the like.
As the resin used for integrally forming the roll paper holder, any kind of resin can be selected according to processability, strength, and durability, and examples thereof include polypropylene, ABS resin, methyl methacrylate resin, and polycarbonate.
