Description

[Detailed description of the invention] This invention relates to a storage tube for storing documents such as certificates, certificates, and drawings.

Conventionally, as a storage cylinder of this type, a so-called paper cylinder is generally known, which has a structure in which a fitting opening is provided at the open end of a cylindrical cylinder main body, and a cylindrical lid is fitted into the fitting opening. The disadvantage of this paper tube was that because the documents to be stored were raw versions, it was difficult to remove the documents if they got stuck in the slot.

The present invention provides a new document storage tube that allows documents to be easily taken out even if they are inserted into the storage tube.The details will be explained below with reference to the drawings.

In FIG. 1, a rim ring 2 made of a hard synthetic resin such as ABS resin is provided at the upper end of the opening of a cylindrical tube body 1 with an open upper end, and the ring 2 includes a short cylindrical holding part 3 and a holding part 3. It consists of a flange part 4 larger than the holding part 3 provided on the side of the cylinder body 1, and a plate-shaped support 5 of an appropriate length that projects upward along the generatrix direction is protruded from this ring 2. A rectangular elastic cover plate 6 of an appropriate width made of a thin elastic plate of hard elastic synthetic resin such as hard vinyl chloride resin is fixed to one side of the support column 5 with one side thereof oriented perpendicularly to the pillar 5.

A groove 7 extending from the annular end face of the flange portion 4 to the tip of the support post 5 along the outer surface of the holding portion 3 is provided on both sides of the support post 5.
7, and one side of the cover plate 6 is fitted and glued into one of the grooves 7, and the cover plate 6 is normally (when the lid is removed) a substantially flat plate as shown in the first figure. It extends from the support 5 in a shape or a gently curved shape, and when it is bent into a cylindrical shape and the tip end of the covered root is inserted into the other groove 7 of the support 5, the outer circumferential surface of the ring holding part 3 comes into contact with one side. It is designed to form a cylindrical cover that is continuous with the cylinder body 1.

The lid 8 is made of synthetic resin such as polypropylene or hard polyethylene, and has an inner diameter that can be fitted into the cylindrical cover of the cover plate 6, and has a notch 9 in its peripheral wall into which the support column 5 is to be fitted.

In use, the award certificate P is rolled up and inserted into the cylinder body 1 shown in the first figure, and then the cover plate 6 is bent into a cylindrical shape and its tip end is inserted into the groove 7 of the support column 5, whereby the award certificate P is inserted. A cylindrical cover is formed to cover the upper part of the cylindrical cover, and in this state, the lid 8 is fitted over the upper end of the opening of the cylindrical cover (FIGS. 2 and 3).

To take out the certificate P, remove the lid 8 and the cover plate 6 will open into a flat plate shape as shown in Figure 1 due to its elastic restoring force, thereby exposing the upper part of the certificate P, so remove it with your fingers. Pull it out.

In another embodiment shown in FIG. 4, plates 6a, 6a are fixed to elastic covers on both sides of the column 5a, and the tips of both cover plates 6a, 6a are overlapped to form a cylindrical cover. This is an example in which the other structures are substantially the same as those on the upper side.

According to the document storage tube of this invention, even if the stored document is a flat version, when the lid is removed, the cover plate opens wide due to its elastic restoring force, allowing the stored document to be exposed so that it can be picked up. Furthermore, when the document is stored, the cover plate forms a cylindrical cover to cover and protect the document, which is extremely convenient in use.

Claims (1)

[Claims for Utility Model Registration] A column is provided at the open end of a cylindrical body and protrudes along the generatrix direction thereof, and a rectangular elastic cover plate is oriented perpendicularly to the column on the side surface of the column. Cover plate - Fixed at the sides, the cover plate normally extends from the support in a flat or curved shape, and when bent into a cylindrical shape, forms a cylindrical cover that is continuous with the cylindrical body. A document storage tube equipped with a lid that removably fits onto the cylindrical cover of the cover plate.
