That is, since the veneer 2 as a raw material is a single solid material, the fiber direction is also unidirectional, and due to the nature of wood, it has twists and warps. In order to suppress those properties and at the same time provide strength reinforcement, it is necessary to form the bottom wall and the side wall at least at several places. In addition, the reinforcing protrusion 1
The shape, the number and the depth of a must be appropriately changed depending on the shape and thickness of the container.

しい。A method for manufacturing a wooden veneer container according to an embodiment of the present invention is a method for manufacturing the wooden veneer container 1 described above. In this manufacturing method, first, the wood 3 is sliced by a slicer to obtain a thin veneer 2 having a thickness of about 0.1 mm to 3.0 mm (see FIG. 2). The type of wood 3 is not particularly limited, but conifers are preferable in consideration of the beauty of the finish.

After immersing in the boiling water in (1), it is softened by immersing in water (5 ° C to 10 ° C). Depending on the type of wood 3 (for example, cedar), it can be softened only with water.

に噴出させる（図４）。Subsequently, the softened veneer 2 is molded into a container shape by applying constant pressure and heat between the upper mold 5 and the lower mold 6, and at the same time, a plurality of bottom walls and side walls are formed. The reinforcing protrusion 1a is formed. The pressure and heat applied by the upper mold 5 and the lower mold 6 evaporate the moisture from the veneer 2 to turn the moisture into high-pressure steam S, and the high-pressure steam S compresses the veneer 2. Then, the high-pressure steam S is ejected at a stretch from the steam holes 7a formed between the upper die 5 and the lower die 6 by the pressure (FIG. 4).

須構造である。In the above step, the veneer 2 once softened (containing a sufficient amount of water) with hot water or water is used as an upper die 5 and a lower die 6.
It is placed between and to apply pressure, but at this time, it is necessary to gradually apply pressure while performing softening of the veneer 2 by reheating to perform molding, and to instantaneously dry. Therefore, the steam S generated by being heated from both molds during mold molding is confined between both molds (molding space 7), and the high pressure when the confined steam S becomes a high pressure state The water vapor S is made to escape to the outside at once by using it. The steam holes 7a are an essential structure for exhibiting such an action.

Although it is preferably about mm, the numerical value can be roughly obtained by multiplying the wall thickness of the veneer 2 to be molded by the veneer shrinkage rate and a predetermined coefficient.

Thereby, the wooden veneer container 1 is manufactured. The wooden veneer container 1 manufactured by this manufacturing method is sterilized by ultraviolet rays and then packaged in a vacuum pack and stored or transported.

The manufacturing die 4 is made of aluminum and is subjected to Teflon (registered trademark) processing, and includes an upper die 5 and a lower die 6 having a heating function. Then, in the mold closed state, the upper mold 5
A molding space 7 having the same shape as the wooden veneer container 1 and having a substantially sealed state is formed between the lower mold 6 and the lower mold 6. This molding space 7
The single plate 2 pressurized inside is molded into a container shape, and compression molding is performed with the high-pressure steam S.

A concave portion 5a is formed on the corresponding portion of the convex portion 6a. By fitting the convex portion 6a and the concave portion 5a, the reinforcing protrusion 1a is formed therebetween. Further, steam holes 7a are formed at eight positions between the upper mold 5 and the lower mold 6 at a plurality of end portions of the mold so as to communicate the molding space 7 with the outside air. The high-pressure steam S is ejected from the steam holes 7a by its pressure.

きる。Although the steam holes 7a can be formed in the upper mold 5, the high-pressure steam S can be formed in the lower mold 6.
Since it can be ejected at once, the molding time can be shortened and the wooden veneer container 1 can be finished neatly. That is, as shown in FIG. 7, when the pressure of the high-pressure steam S acts on the container-shaped single plate 2 in the molding space 7, the single plate 2 is compressed toward the upper mold 5 side due to the specific gravity, A void 7b is generated on the mold 6 side. This void 7b
Communicates with the steam holes 7a formed in the lower mold 6,
The high-pressure steam S can be ejected from the steam holes 7a at once.

It becomes a state. Therefore, the high-pressure steam S in the void 7b cannot be ejected from the steam hole 7a at once. as a result,
Vessel-shaped veneer 2 in a dry state after all high-pressure steam S has escaped
Takes a long time to be manufactured, and the upper die 5
Then, the surface of the lower mold 6 is burnt by the heat of the lower mold 6, and the container 1 has no product value. For these reasons,
The steam holes 7a are preferably formed in the lower mold 6.

木製単板容器の製造方法。1. A piece of veneer, which is a piece of thin wood, is impregnated with water, and then the veneer is produced by molding with an upper die having a heating function and a lower die and steam pressure molding. A container having a plurality of reinforcing protrusions formed on the bottom wall and the side wall by the molding and the steam pressure molding.
A method of manufacturing a wooden veneer container, in which a veneer obtained by slicing wood is softened by immersing it in water or hot water, followed by boiling, and then softening the veneer into an upper mold and a lower mold. A constant pressure and heat are applied between the two to form a container shape and a plurality of reinforcing protrusions are formed on the bottom wall and side walls of the container to evaporate the water from the veneer into high-pressure steam. After compressing the veneer with high-pressure steam, the high-pressure steam is jetted out at a stroke from the steam holes formed between the upper mold and the lower mold, and the container-shaped veneer is formed at the time of molding or after opening one side. A method for manufacturing a wooden veneer container, characterized in that the edges of the container are cut.
