Description

This device is designed to have a curved surface with a curved surface with a thickness of 3 mm or more using a stack of thin wooden plates. It is related with a plate container and its manufacturing method.

Conventionally, as this kind of container with a lid having a lid shape, a lid tube made of synthetic resin or cardboard is also fitted to be openable at the opening end of a bottomed cylindrical main tube made of synthetic resin or cardboard. Such a configuration is 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. .

On the other hand, a configuration of a cylindrical wooden container is disclosed. However, a cylindrical wooden container is proposed by boring a single piece of wood in the axial direction (Patent Document 1). reference). Further, in a cylindrical container having a bottomed cylindrical main cylinder and a lid cylinder for opening and closing the opening of the main cylinder, the main cylinder and the cover cylinder are wound so that the wooden thin plate is inclined with respect to the axis. A wooden cylindrical container has been proposed in which a step-shaped decorative portion is formed on the outer peripheral surface of the main cylinder and the lid cylinder by the edge of the thin plate (see Patent Document 2).

Further, a flexible parquet and rectangular strip-like thin plate obtained by cutting a composite wood obtained by bonding a plurality of wood pieces in series into a thin plate so as to be longitudinally cut in the series direction is a flat cylinder. A thin-walled body formed by bending into a form, a bottom plate fitted in a circumferential annular groove formed in a lower inner peripheral surface of the body, and closing a lower opening of the body, and the body A wooden barrel-shaped container that sits on the upper end surface of the part and closes the upper opening of the body part, a member that is fitted on the outer periphery of the body part, and whose vertical side walls are parallel to each other from the upper end to the lower end Has been proposed (see Patent Document 3).

Produces a laminated board that is laminated with a plurality of wood slice veneers, including at least 2 to 4 wood slice veneers that are laminated so that the fiber directions of the thin plates cross each other, and presses the laminate It has been proposed that a lid for a wooden food container including a step for producing a wooden container and a lid for a wooden container provided with a container body and a protruding edge on the outer periphery thereof can be manufactured (see Patent Document 4).

As a container having a circular shape including a bottomed circular main cylindrical body 2 and a lid cylindrical body 3 for opening and closing the opening of the main cylindrical body, coniferous forest, fir, and cypress Diameter of thin timber with a thickness of 0.5 to 2 mm of cedar and pine wood, with an annual ring width in the range of 0.5 to 3 mm on average A thin plate container with a lid having a circular shape composed of a main cylindrical body 2 with an inner bottom 6 having a circular shape of 50 to 300 mm and a lid cylindrical body 3 with an inner lid 7 has been proposed ( (See Patent Document 5).

In addition, an oval or circular lunch box manufactured by circular bending of the side plate is an oval or circular container having a width or diameter of 50 to 100 mm and a volume of 300 to 1500 ml, and a thickness of 0.8 to 1.2 mm. The side plate 6 laminated with a thin plate is made to have a thickness of 2 to 3 mm, and the bottom plate 4 and the cover plate 5 are made to have an elliptical or circular flat plate with a thickness of 5 to 10 mm. A small circular lunch box with a length of 50 to 100 mm, a lateral length of 50 to 200 mm, a height of 50 to 60 mm, and a circular bent portion with a radius of 25 to 75 mm has been proposed (see Patent Document 6). However, an elliptical or circular container having a square R curved surface has not been obtained.

Box-shaped and circular containers as R-curved containers using thin flat plates as described above are cut into grooves on the R-curved surface and bent, or for the production of side plates, The board was bent into a curved shape, and it took a lot of skill and effort to operate. Further, in the case of thin flat plates, thin plates are wound in three or more layers, four or five layers, and the adhesiveness and design of each thin plate are not sufficient, resulting in a device for the bonding processing method. In particular, the possibility of using a thin wooden plate with a special pattern as the material is expected on the external surface of the design. Further, there has not been such a wooden thick laminate container that is robust as a box-shaped container, such as a small R-curved surface having a flat circular pattern with a surface grain pattern.

In the case of manufacturing a circular box-shaped or cylindrical container having an R-curved surface of a wooden thin plate, the thin flat plate is generally damaged or cracked, and a sufficient yield of the container cannot be obtained. If a plurality of wooden containers having the same diameter are to be produced, wood more than twice the outer diameter of the wooden container is required, which directly leads to waste of raw materials. Therefore, it is difficult to obtain a sufficient strength with a laminated body of three or more side plates laminated with a thin plate of about 0.8 to 1.2 mm. It is difficult to bend, and the curved surface portion is bent by inserting several notch grooves, or immersed in hot water, and then it is subjected to a load and bent into a circular shape. In general, a box-shaped one having an R curved surface is not manufactured. In the production of such a container, it is difficult to prevent breakage and the operation is complicated.

Further, in the case of a rectangular cylindrical container having an R-curved shape, it is very difficult to make only 0.5 mm or less circular when manufactured with a thin flat plate. It has been difficult to produce a wooden box container having a small outer diameter of the laminated wooden thick container. Moreover, in the prior art, the outer peripheral surface of the thick wooden container does not exhibit a woody characteristic, is not decorated, and is extremely uninteresting. Further, containers using thin veneers are not sufficient in strength, and they have devised the bonding method, or made of resin as a material. However, the possibility of a simple method of manufacturing a small-diameter R-curved box-shaped container using a special wooden thin plate is expected.

Further, in the conventional configuration, since a plurality of wooden thin veneers are used in the laminate, in each layer in which a plurality of wooden thin veneers are wound and laminated, the winding start edge and the thin single plate Since the winding end edge is joined to the end edge by an adhesive, it is necessary to change and adjust the width of the thin flat plate of each layer so as to gradually increase toward the outer layer, and there are many gaps. There was a problem that it was not possible to use wooden thin plates of the same shape, and the processing of the thin plates was troublesome. Furthermore, a material capable of strength with a thin wooden plate was required.

In addition, the butt joint of the outermost surface wood grain pattern thin veneer appears on the outer peripheral surface of the wooden thin plate container so as to extend linearly along the axis of the container on the same peripheral surface as the outer peripheral surface of the container. It is configured. Even when a thin container made of wood and a laminated container of side plates were used to form a circular container, it was not possible to obtain a substantially rectangular cylindrical container that was easy to process and excellent in design.
