Description of the invention (1) [Technical Field of the Invention] The present invention relates to a thermoforming method and device for a plastic container having a flange; in particular, it relates to polypropylene, polyethylene, polyparaphenylene Thermoplastic sheet of ethylene diformate, polyvinyl chloride, etc., method and apparatus for thermoforming 9 [prior art] In the past, various techniques have been proposed for manufacturing containers from plastic sheets. For example, a method of casting a plastic sheet cut into a rectangular shape into a circular dish shape and pressing this into a container is disclosed in Japanese Patent Laid-Open No. Sho 47-4585. This method is called waste-free forming (SFP) and is actually a technique that has been used. However, because this technology uses a rectangular plastic sheet to cast a circular dish, it causes a change in the circular dish. In addition, it is difficult to obtain a shaped dish as it is by using a multilayered thin layer to maintain an even layer structure. : Furthermore, for casting and pressure forming, complicated and large-scale equipment is required, and productivity is poor, and versatility is lacking. Many other techniques for forming a circular dish container after casting a circular dish from plastic have also been proposed, but all have the same problems as those described above. Printed by the Central Bureau of Standards, Ministry of Economic Affairs, Machining Consumer Cooperatives. In addition, Japanese Patent Publication No. 48-11817 describes a cold forming method for forming a container having a uniform thickness from a special shaped plastic forming plate. It is difficult to manufacture, and it is not suitable for multilayer systems. In addition, in Japanese Patent Laid-Open No. 4-7-8089, a method has been proposed in which a plastic molded plate is continuously contacted between heating plates to be maintained and heated. However, according to this technology, the plastic paper slides and is transported and heated.

Description of the invention (2) Between the heating plates installed in the row: If the plate temperature or the slip of the surface of the plastic forming plate is slightly wrong, the forming plate is deformed. , Can not achieve practicality. In this patent, Japanese Patent Publication No. 6-8 8 3 2 8 and Japanese Patent Application Laid-Open No. 2 1 15 0 3 38 propose to maintain the outer edge portion of the plastic molding plate in the solid state area, and only mold the central portion. Field heating to a molten state to form a technology that can heat a container. However, this technology is a so-called indirect heating method in which the forming plate is heated in a oven having a temperature higher than the melting point of the plastic for a predetermined period of time. Special measures are not good for costs. In addition, because the entire molding area is heated at a high temperature for a long time, the outer edge portion also tends to expand and change due to heat conduction. In order to suppress this phenomenon, a new problem that requires the use of cooling means has been raised. . . . [Problems to be Solved by the Invention] In order to eliminate the disadvantages of these conventional technologies, the present invention aims to efficiently manufacture a container from a plastic molded plate.

A convex strip 2 1 b is annularly arranged on the upper end surface of the mold 21, and at the same time, the Chinese strip (applicable to the Chinese standard (CNS) A4 specification (210X297)) is applied to the paper size with this convex strip. -19- 4 46 61 5 Λ7 B7 V. Description of the invention In the (17) direction position, a groove 2 3 a is annularly provided on the lower end surface of the pressing body 23, which is in close contact with the operating position of the mold 21 and the pressing body 23, so as to press the plug 2 2 and the compressed air. When the container is formed, unevenness is formed at the flange portion sandwiched between the convex strip 2 1 b and the concave groove 2 3 a at the same time. In this case, it is necessary to heat and soften the hot plate 19a, 19b of a heating device (FIG. 6) until the uneven flange portion is formed. However, as for the "forming device 20 of Figs. 7 and 8", as described above, "When the forming part 10 a of the forming plate is heated above the melting point", the plug 2 2 is not necessarily required. E Central of the Ministry of Economy Standard Bureau employee consumer cooperative prints the forming device 2 0 0 'constructed as shown in Fig. 11 to hold the part of the outer edge portion 1 0 b of the forming plate being heated and softened between the convex strip 2 lb and the groove 2 The bird container flange 3 is formed in a concave-convex shape corresponding to the shape of these ridges 2 1 a and the grooves 2 3 a between 3 a, but the concave-convex formed part of the outer edge portion 1 0 b of the forming plate is previously formed. The heating position is sufficiently heated and softened, so it is not necessary to form a groove 2 3 a corresponding to the uneven shape on the lower end surface of the pressing body 23. That is, as shown in FIG. 12, at a position opposed to the ridges 2 1 b provided on the upper end surface of the mold 21 in a ring shape, the ridges formed on the surface side of the flange are accommodated in a clamp. The lower end surface of the body 2 3 may be provided with a recessed portion 2 3 b in a ring shape, or as shown in FIG. 13, on the outside of the convex strip 2 1 b so that it has a leg portion sandwiching the outer edge portion 1 Ob of the forming plate. The clamp body of 2 3 c 2 3 is also available. When the pressing device directly contacts the outer edge portion 10 b of the forming plate when the forming device is in the actuated position, the outer edge portion 10 b of the pressure forming plate is damaged, and there is a risk that the pressure cannot be applied to the flange 3 of the container 1 ( (Fig. 5) Chinese paper standard for maintaining the specified meat thickness is applicable to the Chinese National Standard (CNS) A4 (210X 297 cm) -20-Economic and Trade Commission-Printed by the Central Bureau of Standards for Industrial and Consumer Cooperatives ¾ 4 46 61 5 A7 B7 V. Description of Invention (18) Question. The forming apparatus shown in Figs. 12 and 13 has a solution to this problem. That is, the gasket 2 0 1 is attached to the lower side of the side extension 2 3 1 of the clamping body 2 3, and the gasket 2 0 1 is elastically engaged with the forming board seat when the clamping body 2 3 is lowered during molding. A cavity 2 1 a in the mold 2 1 is air-tightly held on a peripheral edge portion of the frame 12. In this way, the outer edge portion 1 0 b of the forming plate is not crimped even when the pressing body 2 3 is lowered to the actuating position. A slight gap between these can also prevent air from leaking out of the cavity 2 1 a. However, , On the 1st 1 ~. The forming plate holder 12 shown in FIG. 13 is a simplified one of the forming plate holder 1 2 0 of the appropriate embodiment shown in FIG. 10, and it is in the direction protruding from the inner peripheral surface. The molding plate fixing ball 37 is possible to keep the molding plate outer edge portion 10 b in a proper position. ~ 'FIG. 14 is a diagram showing a modification of the heating device. The heating device 180 is composed of a lifting mechanism (not shown) having an upper and lower hot plate 190 a, 190 b, and each of these hot plates is moved up and down. It is the same as the heating device 18 (Figure 6) described above, but as shown in Figure 15, each hot plate penetrates through the thickness direction and is provided with air injection holes 1 8 1, 1 8 2 »This The spray holes are formed on the hot plate, which is heated in a state of being crimped between the hot plates. After being melted, it is easy to adhere to the hot plate. Therefore, after heating the shaped plate at each heating position, the hot plate is separated by a lifting mechanism. At this time, high-pressure air is sprayed toward the forming plate through the air injection holes 1 8 1, 18 2 to prevent the forming plate 10 from adhering to the hot plate 19 0 a, 19 0 b.
