Description

[Detailed description of the invention] The present invention relates to a tubular container for storing paper materials such as certificates of merit and drawings, and more specifically, the invention relates to a tubular container for storing paper materials such as certificates and drawings. The present invention relates to a characteristic cylindrical container.

In the past, when conventional cylindrical containers were used to store paper materials such as certificates and drawings, they were rolled into a tube with a diameter smaller than the inner diameter of the face and inserted into the tube. .

However, the object is then unwound radially outward within the cylinder due to the waist force inherent to the member and comes into close contact with the inner surface of the face.

Therefore, when taking out the paper product to be accommodated from the cylinder, place your finger inside the tubular product inside the cylinder and roll the product in the cylinder so that the outer surface of the product is released from the inner surface of the cylinder and becomes a small diameter tube. It was necessary to go into it.

Such work not only makes it inconvenient to take out the product, but also causes the product to become dirty or damaged.

In order to eliminate this drawback, the present invention aims to make it possible to easily take out the articles stored in the cylinder.

FIG. 1 shows a cross section of a cylindrical container 10 according to the present invention, and the container 10 is separated from a container body 1 and a lid 2 thereof.

Both the container body 1 and the lid 2 may be of known type.

At least one axially elongated rib 3, preferably made of cardboard or other suitable material, is glued to the inner wall of the body 1 of the container 10 of the invention.

The ribs 3 are preferably cut from a piece of cardboard material, for example, which is wider at one end than the other, as shown in FIG.

The center portion 4 of the rib 3 is mountain-folded in the axial direction, and portions 5 and 6 left and right at a predetermined distance from the central portion 4 are valley-folded from the outer edges 7 and 8 with a predetermined gap.

Therefore, the rib 3 has a height in a cross section perpendicular to the axial direction of the center portion 4 as it goes from the other end to the first end.

However, this is not a requirement.

The length of the riff is preferably equal to the length of the body 1◇ or slightly shorter than that as shown in FIG.

After forming the ribs 3 with mountain folds and valley folds, respectively, as shown in FIG. 1 above to the inner surface
Guide the end so that it is located at the bottom of the main body 1 and fix it there.

According to this invention, it is desirable that the ribs 3 form a land protruding portion extending from the inlet of the main body 1 to the back or bottom of the container from the inner wall surface of the container.

In this S, the number of ribs 3 does not need to be one.

When storing the sheet member 9 in the tube container 10 in this invention, as is well known, the sheet member 9 is rolled up into a tube shape with a diameter 1 smaller than the inner diameter of the main body 1, and the sheet member 9 is kept in the tube body 1 in that state. Insert it into the

However, in the present invention, unlike known cylinders, at least one rib 3 such as a lower part is attached to the inner surface of the cylinder, so that after storing the sheet member, the wrung sheet member 9 is applied to the main body by the waist force, that is, the unwinding force inherent to the sheet member. Even if the sheet member 9 spreads outward in the radial direction so as to come into close contact with the inner surface of the sheet member 9, once the two outer portions of the sheet member 9 come into line contact with the central peak portion 4 of the rib, the sheet member 9 will no longer be expanded or rewound.

Therefore, in the present invention, when taking out the sheet member 9 from the cylinder main body 3, the sheet member 9 can be pulled out while moving along the central mountain part 4 of the rib 3 in the shape of the housed o Σ. Since the contact between the sheet member 9 and the inner wall surface of the container is restricted, the sheet member can be taken out into the container.

In this case, the medium volcanic portion 4 also serves as a sliding guide for the sheet member 9.

Furthermore, in certain cases, the rib 3 is higher at the back of the main body 1 than at the entrance, so that the sheet member will have a larger diameter at the entrance and a smaller diameter at the bottom due to the unwinding force of the sheet member within the tube. It is then stored in a truncated conical shape.

In this way, the sheet material 9 forms a so-called tapered tube in which the bottom part has a smaller diameter than the inlet part in the container 10, and since the sheet material tube is in line contact with the rib 3, its removal is further facilitated. It becomes easier.

This is because as this tubular storage sheet member 9 is pulled out toward the inlet of the main body 30, the small diameter portion at the bottom of the material becomes further separated from the main body 3, making it easier to pull out, and also because the sheet material is in line contact with the rib upper part 4. Since there are few friction surfaces and the ridges 4 allow the sheet material to be taken out in a fixed direction, twisting of the sheet material during taking out and damage caused by it can be completely prevented.

In the present invention, as shown in FIG.
Although it is necessary to attach the rib 3 to the inner wall surface of the tube so that gh does not decrease as it approaches the bottom of the tube, it is also possible to form the rib 3 from the beginning into the shape shown in FIG. 3, for example, from a plastic material. In this case, it may be considered that adhering the ribs to the inner wall surface of the container is no longer an essential requirement.

The height h of the rib at the pipe entrance may be several square meters, and if the rib is inclined in the axial direction, the angle of inclination may be on the order of several degrees.

Furthermore, the cross section of the rib does not have to be triangular as exemplified in the present invention, but may have a round, circular or other shape.
