Description

  The present invention relates to a cylindrical container that is used for accommodating, for example, an award certificate or a diploma in a state of being wound in a cylindrical shape.

  Conventionally, this type of cylindrical container is configured such that a cover cylinder made of synthetic resin or cardboard is also fitted to the open end of a bottomed cylindrical main cylinder made of synthetic resin or cardboard so that it can be opened and closed. It has been known. In this conventional configuration, since the main tube and the cover tube are formed of synthetic resin or cardboard, it is difficult to expose a natural material pattern such as a wood grain pattern on the outer peripheral surface of the main tube and the cover tube. . In particular, those made of cardboard are fragile to water and external forces, and must be handled with care.

  On the other hand, in patent document 1, the structure of a cylindrical wooden container is disclosed. In the conventional configuration of Patent Document 1, a cylindrical wooden container is formed by boring one piece of wood in the axial direction.

Moreover, the structure disclosed by patent document 2 is proposed as a wood pipe used for wooden members, such as a welfare tool and a learning desk chair for schools. In the conventional configuration of Patent Document 2, a cylindrical wood pipe is formed by winding and laminating a plurality of thin wooden single plates and bonding and fixing them. In this case, the winding start edge and the winding end edge of the thin single plate of each layer are joined in a butted state so as not to overlap each other, and are arranged so as to extend in parallel with the axis of the wood pipe. Further, the butt joints of the thin single plates in each layer are arranged so as to be displaced in the circumferential direction of the wood pipe so as not to overlap at the same position.

  In the configuration of Patent Document 1, if a plurality of wooden containers having the same diameter are to be produced, wood that is twice or more the outer diameter of the wooden container is required, which directly leads to waste of raw materials. Therefore, only wooden containers with different diameters can be made from wood less than twice the outer diameter of the wooden container. And in the prior art of this patent document 1, no decoration is given to the outer peripheral surface of a wooden container, and it is very interesting.

  Further, in the conventional configuration described in Patent Document 2, since a plurality of thin wood single plates are used, the problem of waste of raw materials as in Patent Document 1 does not occur. However, in the conventional configuration described in Patent Document 2, in each layer in which a plurality of woody thin single plates are wound and laminated, the winding start edge and the winding end edge of the thin single plate are joined in a butted state. Therefore, it is necessary to change and adjust the width of the thin single plate of each layer so that the outer layer gradually becomes wider. Therefore, there is a problem that thin single plates having the same shape cannot be used, and the processing of the thin single plate becomes troublesome.

  Further, in the conventional configuration described in Patent Document 2, the butt joint of the outermost thin single plate is linearly formed on the outer peripheral surface of the wood pipe along the axis of the pipe on the same peripheral surface as the outer peripheral surface of the pipe. It is configured to appear so as to extend. For this reason, there also existed a problem that a three-dimensional design change could not be brought out on the outer peripheral surface of a wood pipe.

  Therefore, even if the main cylinder and the cover cylinder of the cylindrical container are formed from the thin wood single plate using the wood pipe manufacturing technology described in Patent Document 2, a cylindrical container that is easy to process and excellent in design can be obtained. Couldn't get.

  The present invention has been made paying attention to such problems existing in the prior art. The object is to provide a cylindrical container that is easy to process and that can bring about a three-dimensional design change of the natural material on the outer peripheral surface.

  In order to achieve the above object, the present invention provides a cylindrical container having a bottomed cylindrical main cylinder and a lid cylinder that opens and closes an opening of the main cylinder. And a step-shaped decorative portion is formed on the outer peripheral surface of the main cylinder and the cover cylinder by the edge of the thin plate.

  Therefore, when manufacturing the main cylinder and the lid cylinder in this cylindrical container, it is not necessary to butt-join the winding start edge and the winding end edge of the wooden thin plate for each layer, and the thin plate is continuously wound and formed. be able to. Therefore, it is not necessary to prepare a plurality of wooden thin plates having different widths, and the processing can be easily performed. In addition, because the outer peripheral surface of the main cylinder and the cover cylinder is formed with a step-shaped decorative portion by the edge of the thin wooden plate, the three-dimensional design change of the natural material is brought about on the outer peripheral surface of the cylindrical container. Can do.

  Moreover, the said structure WHEREIN: It is good to incline the said decoration part with respect to the said axis line. When comprised in this way, a step-shaped decoration part can be visually recognized from multiple directions of the outer peripheral surface of a cylindrical container, and a design effect can be heightened.

  Further, in the above configuration, the main cylinder is constituted by an inner cylinder and an outer cylinder, and a protruding cylinder portion protruding from an opening end portion of the outer cylinder is formed on the inner cylinder, and the lid is formed on the protruding cylinder portion. A cylinder is configured to be fitted externally, and when the decorative part on the outer cylinder and the decorative part on the lid cylinder are continuous between the protruding cylinder part and the lid cylinder, the lid cylinder is formed into the protruding cylinder part. On the other hand, positioning means for positioning in the rotational direction may be provided. When configured in this manner, the lid tube can be attached to and detached from the main tube in the form of a seal cover, and a step-shaped decorative portion is appropriately provided between the outer surface of the main tube and the lid tube.
