Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a storage container for roll paper, such as a rolled up long paper towel, and in particular, the storage container for storing rolled paper is always carried out in a favorable condition. This relates to storage containers.

(Prior Art and its Problems) Generally, roll paper is used by rotating the roll paper around its core and taking out a desired amount of paper. Therefore, if the roll paper is supported so that it can rotate too freely, the paper will be pulled out more than necessary, which is undesirable, and vice versa. This is not preferable because it will tear at certain parts.
Therefore, it is desirable that the roll paper be supported in a state where a predetermined resistance force exists against rotation.

However, the width dimension of the roll paper usually has manufacturing variations of about ±4 mm, which makes it difficult to support the roll paper in a state that allows the desired rotational movement as described above. In particular, it is difficult to store roll paper in a container with fixed dimensions in a state where the desired rotation is achieved.
It has not been practiced to store roll paper in a container of a certain size and then draw out the required amount for use.

The present invention has been made in view of this point, and an object of the present invention is to provide a storage container that allows roll paper to be pulled out in a favorable condition at all times.

(Means for Solving the Problems) To this end, the storage container of the present invention has a support surface for supporting both end faces in the width direction of the roll paper in the container body in which the opening for taking out the roll paper is formed. The supporting surface rotatably supports the roll paper around its winding core, and an elastic member is inserted in a compressed state between at least one end surface of the roll paper and the supporting surface. At the same time, this elastic member is arranged to come into contact with the end surface of the roll paper from the inner peripheral end to the outer peripheral end of the end surface. Note that these contact states can be linear, curved, band-like, or planar.

(Function) In the storage container configured as described above, the roll paper is rotatably supported by both support surfaces, and is always pressed against one support surface with a predetermined force by the elastic force of the elastic member. . That is,
Even if the width of the roll paper varies due to manufacturing errors, the roll paper will always be pressed against the support surface with a predetermined force by the elastic force of the elastic member placed in a compressed state.
Furthermore, if the contact between the end face of the roll paper and the elastic member is made in the form of a line or a thin strip, the frictional force generated between the end face and the elastic member is small, and therefore,
Even when the pressing force exerted by the elastic member increases, the roll paper does not become difficult to rotate.
Furthermore, if the contact area between the paper roll end face and the elastic member is made to extend from the inner peripheral end to the outer peripheral end of the roll paper end face (for example, if it is formed over the entire radial width of the roll paper end face), the roll paper Even when the amount remaining is low, the end face of the roll paper remains in contact with the elastic member, and therefore the roll paper is pressed with a predetermined force.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows the appearance of the container of this embodiment, and this container is composed of the parts shown in FIG. 2. That is, 1 is a cylindrical body with openings at both ends, and an opening 1a for taking out the roll paper is formed in the outer circumferential wall of the cylindrical body. Caps 3 and 5, each having a substantially sheared shape, can be fitted into the openings at both ends of the cylindrical body 1. The cylinder body 1 and the caps 3 and 5 constitute a container body. In both of these caps 3 and 5, flanges 3b and 5b that can be hooked onto the edges 1b and 1c of the cylinder 1 are formed on one end side of the outer peripheral walls 3a and 5a that can be fitted inside the cylinder 1. Cylindrical projections 3d and 5d are formed at the center of the circular bottom walls 3c and 5c on the other end side. Reference numeral 7 denotes a roll paper that can be inserted into the cylinder 1, and the winding core 7a has protrusions 3d and 5 of the caps 3 and 5.
d can be inserted. On the other hand, reference numeral 9 denotes an elastic plate, which has an outer diameter that allows it to be inserted into the cylindrical body 1.
This elastic plate 9 is formed by, for example, making a circular hole 9a in the center of a polypropylene circular plate through which the protrusion 3d of the cap 3 can be freely inserted, and then bending it at a predetermined angle along one diameter of the circular hole 9a. This is what I did. Therefore, this elastic plate 9 has a wide V-shaped side surface shape, and bent projections 9b and 9c formed by bending are formed in a straight line.

In this embodiment configured in this way, the second
As shown in the figure, after fitting the cap 5 into the cylinder 1, insert the roll paper 7 from the other opening side of the cylinder 1, and then insert the elastic plate 9 so that its protrusions 9b and 9c face the roll paper 7. By inserting the cap 3 as shown in the figure and then fitting the cap 3 into the cylinder body 1,
Roll paper 7 is rotatably supported within cylindrical body 1. That is, the protrusions 3d of both caps 3 and 5,
5d fit into the take-up core 7a of the roll paper 7 from both sides, forming the rotation axis of the roll paper 7. When the end of the roll paper 7 is pulled out from the opening 1a of the cylinder 1, the roll paper 7 rotates around the winding core 7a, and a predetermined length of paper is taken out.

Here, as shown in FIG. 3, an elastic plate 9 is inserted between the end surface 7b of the roll paper 7 and the cap 3. As mentioned above, this elastic plate 9 has a wide V-shaped side surface shape, and is indicated by the dashed-dot line A.
It is in a compressed state compared to the normal state shown in . Therefore, the elastic force of the elastic plate 9 presses the roll paper 7 toward the other cap 5 with a predetermined force. Furthermore, only the linear protrusions 9b and 9c of the elastic plate 9 are in contact with the end surface of the roll paper 7. Therefore, a suitable resistance force is generated in the roll paper 7 supported between the caps 3 and 5 against its rotation. That is, the cylinder opening 1
When pulling out the edge of the roll paper from a, applying only a small pulling force will not cause the roll paper to rotate a lot and take out a large amount of roll paper; on the contrary, applying a large pulling force However, the roll paper never stops rotating. The roll paper can be pulled out with the desired resistance.

Such a suitable holding state is maintained even when roll papers 7 of different widths are stored.
That is, as shown by the dashed-dotted line 7b' in FIG.
If the roll paper 7 is wide, the elastic plate 9
is further compressed as shown by the two-dot chain line B, thereby absorbing variations in the width of the roll paper 7. In this case, since the elastic plate 9 is constructed separately from the cap 3, it can freely expand outward in the radial direction. Therefore, even when compressed in this way, the elastic force acting on the roll paper 7 does not change significantly. Furthermore, even if such a fluctuation occurs, since the elastic plate 9 and the end surface 7b of the roll paper are in line contact, the resistance force against the rotation of the roll paper 7 hardly changes. Note that, contrary to the above case, even when a narrow roll paper is stored, the roll paper is similarly maintained in a suitable state.

Here, in this embodiment, a linear protrusion 9 which is a contact area between the elastic plate 9 and the roll paper 7 is used.
b, 9c are formed over the entire width in the radial direction of the end surface of the roll paper 7, so even if the outer diameter of the roll paper 7 becomes smaller due to use, the elastic plate 9 and the end surface 7b of the roll paper are always connected.
A linear contact state is maintained between the two. Therefore,
The roll paper 7 is preferred because it is always kept in a suitable condition until it is completely used.

In the above-described embodiment, the contact area between the elastic member and the end surface of the roll paper is linear, but it can also be formed into a plurality of straight lines or a strip, for example.

(Effects of the invention) As explained above, the storage container of the invention includes a compressed elastic member that contacts the end surface of the roll paper in a predetermined state, so it is not affected by variations in width dimension due to manufacturing errors. In addition, the roll paper can always be stored in a suitable state.
