Description

This device is a design wooden plank laminated container with R-curved surface with a thickness of 3 mm or more using laminated thin wooden plates, with circularly laminated laminated thickness with R-curved surface of surface grain pattern The present invention relates to a method of manufacturing a plate container.

Conventionally, as a container with a circular lid of this type, a lid cylinder made of synthetic resin or cardboard is similarly fitted in an openable / closable manner at the opening end of a bottomed cylindrical main cylinder made of synthetic resin or cardboard. It is known to be configured. In this conventional configuration, since the main cylinder and the cover cylinder are formed of synthetic resin or thick paper, it is difficult to expose a pattern of a natural material such as wood grain on the outer peripheral surface of the main cylinder and the cover cylinder. .

On the other hand, although the configuration of a cylindrical wooden container is disclosed, one in which a cylindrical wooden container is formed by boring a single piece of wood in the axial direction has been proposed (Patent Document 1) reference). In a cylindrical container provided with a bottomed cylindrical main cylinder and a lid cylinder for opening and closing the opening of the main cylinder, the main cylinder and the lid cylinder are wound so as to incline a thin plate of wood with respect to the axis. A wooden cylindrical container is proposed in which a decorative part in the shape of a step is formed on the outer peripheral surface of the main cylinder and the lid cylinder by the end edges of the thin plate while being configured (see Patent Document 2).

Furthermore, a flexible cylinder obtained by cutting a composite jamb wood obtained by bonding a plurality of pieces of wood in series in a thin plate shape so as to cut longitudinally in the direction of the series direction is a flat cylinder And a bottom plate which is fitted in a circumferential annular groove formed in a lower inner circumferential surface of the trunk, and which is closed on the lower opening of the trunk. A wooden barrel-shaped container which is seated on the upper end face of the part and closes the upper opening of the body, a member fitted to the outer periphery of the body but having vertical side walls parallel to each other from the upper end to the lower end Has been proposed (see Patent Document 3).

A plurality of wood slice veneers including at least 2 to 4 pieces of wood slice veneers laminated so that the fiber directions of the lamina cross each other are orthogonally bonded to each other with an adhesive to form a laminate, which is pressure molded It has been proposed that it is possible to manufacture a lid of a wooden food container including the following steps, and also to manufacture a lid of a wooden container provided with the container body and the overhanging rim of its outer periphery (see Patent Document 4).

As a container having a circular shape provided with a bottomed circular main cylindrical body 2 and a lid cylindrical body 3 for opening and closing the opening of the main cylindrical body, spruce wood, fir wood, cypress wood which is a coniferous forest , Cedar wood, pine wood with a thickness of 0.5 to 2 mm and a flat plate with an average ring width of 0.5 to 3 mm. There has been proposed a lidded thin plate container having a circular shape, which is composed of a main cylindrical body 2 having an insertion bottom 6 having a circular shape of 50 to 300 mm and a lid cylindrical body 3 having an insertion lid 7 Patent Document 5).

Also, in an oval or circular lunch box manufactured by bending a side plate, the width or diameter is 50 to 100 mm, the volume is 300 to 1,500 ml, and the thickness is 0.8 to 1.2 mm. The thickness of the side plate 6 laminated using a thin sheet is 2 to 3 mm, and the thickness of the bottom plate 4 and the cover plate 5 is an oval or circular flat plate of 5 to 10 mm, and the container dimensions are vertically long. There has been proposed a small-sized circular lunch container having a length of 50 to 100 mm, a horizontal length of 50 to 200 mm, a height of 50 to 60 mm, and a circular bent portion of 25 to 75 mm in radius (see Patent Document 6). However, oval or circular containers with square R-curved surfaces have not been obtained.

As described above, a box-type or circular-type container as a laminate container with a curved surface using a thin flat plate is notched or bent in the curved surface, or hot water is used to form a side plate. Put in, bent the plank into a curve, and it took skill and effort on operation. In the case of thin flat plates, thin plates are wound in three or more layers and in four or five layers, and the adhesion and design properties of the respective thin plates are not sufficient, and the method of processing the adhesion has been devised. In particular, on the design outer surface, the possibility of using a thin wooden plate with a special pattern as a material is expected. In addition, a small R-curved surface having a circular plate with a surface grain pattern such as this, a circular curved shape, and a rigid wooden thick-layered container as a box-shaped container do not exist until now.

In the case of producing a circular box-shaped or cylindrical container having a curved surface of a wooden thin plate, breakage or cracking of a thin flat plate generally occurs, and a sufficient container yield can not be obtained. If multiple wooden containers of the same diameter are to be made, it will lead directly to the waste of raw materials since it requires more than twice the outer diameter of the wooden container. Therefore, it is difficult to obtain sufficient strength in a laminate of three or more laminated side plates with thin plates of about 0.8 to 1.2 mm, or in a flat plate of 3 mm or more, R-curve, curve, circle easily It is difficult to bend, and some of the grooves of the cut are put in the curved surface and bent or dipped in hot water, and then a load is applied to bend it into a circular curve. In general, box-shaped ones with R-curved surfaces are not manufactured. It is difficult to prevent breakage in the production of such containers, and the operation is also complicated.

In addition, in the case of a rectangular cylindrical container having an R-shaped curved surface, it was very difficult to make a circular curve only for those having a size of 0.5 mm or less when producing a thin flat plate. The production of small diameter wooden box containers of laminated wooden thick containers has become difficult. Moreover, in the prior art, the outer peripheral surface of the thick wooden container does not exhibit the characteristics of wood, and is not decorated at all, which is extremely scarce. Moreover, the container using a thin veneer is not sufficient in strength, and the adhesion processing method has been devised or resin is used as a material. However, the possibility of a method of easily producing a small-diameter R-curved box-like container with a special wooden sheet is expected.

Further, in the conventional configuration, since a plurality of thin wood veneers are used in the laminate, in each layer in which a plurality of thin wood veneers are wound and laminated, the winding start with the thin veneer and the end edge Since the end of the winding is joined with the adhesive in the butt state, it is necessary to change and adjust the width of the thin flat plate of each layer so as to be gradually larger toward the outer layer, and there are many gaps. There is a problem that it is not possible to use a thin wooden plate of the same shape, and the processing of the thin plate becomes troublesome. Furthermore, it was necessary to use a material which is strong in a wooden thin plate.

In addition, a butt joint part of a thin veneer with an outermost surface grain pattern appears on the outer peripheral surface of the thin wooden 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. Is configured. Even when a thin wood veneer is stacked to form a circularly-curved container by a laminate of side plates, it has not been possible to obtain a substantially square cylindrical container which is easy to process and is excellent in design.

The present invention addresses the problems existing in the technical problems of such conventional thin plate containers, and is dealt with design characteristics, strength and the like in a box-shaped thick container with R curved surface. Its purpose is to use a material that is bactericidal and bactericidal, having tenacity by winding three to six thin flat plates with surface grain patterns of about 0.8 to 1.2 mm in the same direction. It is possible to establish a method by which R-curved square container processing can be easily processed, and to create a change in design of wood grain patterns with a three-dimensional surface of a natural material on the outer peripheral surface of a cylindrical container with R-curved surface. An object of the present invention is to provide a square container having an R-shaped curved surface and to form a square-shaped container, and to establish its manufacturing method.
