Thereafter, such steps are repeated several times to obtain a multilayer synthetic resin laminate. However, this method requires the same number of molds as the number of layers in the laminate, which not only makes the manufacturing equipment expensive (
This method has the disadvantage of increasing the number of steps. Yet another molding method uses multilayer injection molding equipment. In this method, a plurality of injection cylinders are provided so as to be connected to the cavity of a single mold, and resin is sequentially injected into the cavity of the mold from these cylinders. However, this method has the problem that the synthetic resins forming each layer mix with each other, making it impossible to obtain a uniform laminate, making it unsuitable for use in manufacturing multilayer containers. It is something.
