'But the hardness is poor, and the degradation of appropriate sunlight, air, water, soil, microbes, degradation is not satisfactory. Usually it is just a small piece, a small piece of mesh is missing. : It is fragile, easy to get wet, not easy to store, etc. More importantly, from the point of view of raw materials, 'use of temple powder production - secondary tableware is a great waste of food. Ming 4, paper tableware: its waterproof, oil-proof, and hardness is not enough, only suitable for cold, dry food, 1 re-made, so it is not conducive to recycling, but there is a lack of use. In view of this, a container made of wood or bamboo flakes, No. 3,153,343, "Method for manufacturing disposable bamboo flakes, environmentally friendly food containers, 1252830, Patent No. 583083", "Flat Composite Materials - Patent Case, and Announcement No. 5 The predicate "thin wood meal, - structure" new patent case 'is two pieces of thin bamboo pieces by adhesive bonding to each other and then money forming, or with a piece of wood flakes combined with the adhesive _ fiber layer and then hot-pressed' , not only can meet, green, and important, and has the characteristics of non-toxic, harmless, decomposable, better hardness, heat resistance, etc. However, it still has the following defects in actual use and needs to be solved: The thin bamboo piece is pre-soaked with the adhesive, and then the hot glue is used to heat-bond the adhesive and adhere to each other. Therefore, in the hot pressing process, the adhesive is 2 into the tissue of the thin bamboo piece, and After cooling The difference between the inlay and the tissue causes the thin bamboo sheet to be cracked easily, and after the molding, the incision has a rough edge and a rough surface, and it must be polished and added twice. A review of the announcement No. 583083 Case No. 569689, although it is possible to prevent the wood chip from being cracked by a fiber layer, but only a container made of a sheet of shellfish is bound to have a shape of the fiber layer in contact with the contents. Therefore, when liquid or high-temperature objects are placed in the valley, it is easy to be decomposed by moisture or high temperature, and the lighter will destroy the taste of the food, and the heavy weight will cause harm to the human body', and also because the incision has burrs and thick chains on the surface. It is necessary to perform one-time processing such as polishing. [Explanation] Therefore, the object of the present invention is to provide a method for manufacturing a wooden container capable of producing practical and environmentally-friendly requirements. The method includes the following steps: Step 'Steps': Preparation, one or more wood chips and a glue film. Step 1252830 Two: transporting and superimposing the wood flakes and the glue film, so that the glue film is crystallized in two wood braids. Step 3: Prepare a mold. Step 4: Pressing the wood chips together with the glue film to heat-melt the glue film and bonding the wood chips together to form a container. The utility model has the advantages of being compatible with, environmentally friendly, and being harmless, decomposable, having better hardness, better water resistance, heat resistance, resistance to microwave, no cracking, and recyclability. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments of the invention. The preferred embodiment of the method of the present invention comprises the following steps: preparing a two-wood sheet 11, 12 and a glue film 13, which is a Melcata (Fallcata Albisia). It is difficult for at least six years (about 35 cm straight), and the thickness is rolled into a thickness of 〇5, and then it is made by moderate drying. The glue film 13 is made of a single glue. - «Fiber material coating or soaking food ν - - conveying and laminating the wood sheet 11 with a plurality of rollers 2 The glue film 13" is superimposed between the two wood sheets 112 and passed through a cutting machine (Fig. Cut (not shown) into a properly long, wide embryo material (Ref. 2). Step 2: A mold 3 is prepared, and the mold 3 has a module 31 and a second module 32 which are opposed to each other. The first module has a recess 312 formed in the top surface 311, and a peripheral edge 313 formed around the top surface 311. The second module 32 has a convex portion 322 formed on a bottom surface 321, and a side 323 formed around the bottom surface 321 and abutting the slit edge 313. Step 4: Referring to Fig. 3, the blank material 1 is placed on the first and second modules 3b and 32' and the heat is pressed (10) to 18 Torr. The first and second modules 31, 32. The mold | 3 is divided into three material materials in the matching process towel (four) force value pressure heating 'first time course, is about 25_55Kg / cm% pressure to heat the embryo material 1 to make the glue film 13 After hot-melt, the wood chips 丨丨, 2 are bonded to the body, and the second time course is to pressurize the seed material under a pressure of about 35_65 Kg/cm 2 to make the wood thin # n, 12 formed on the surface layer. In the case of withstanding high temperature and high pressure, it is pressed into a smooth surface of smoothing, and the third time step = pressurizing and heating the seed material 2 at a pressure of about 35 to 75 Kg/cm 2 to make the second module 32 with the trimming 323 forms a shearing action with respect to the slit edge 313 of the first module 31, and cuts the residual material around the blank of the preform material to form a container 如图 as shown in FIG. Thereby, the container hopper after the demolding can be sold and used only after passing through the UV killing bacteria, the receiving material i, and the vacuum package t.
