METHOD OF MAKING A PLASTIC CONTAINER WITH INTEGRAL CHANNEL |
摘要 |
A method of making plastic containers having walls with fluid circulatable channels integrally formed therein comprises the successive steps of injecting a molten thermoplastic material in a mold cavity having a channel configuration to define, in the container being mold, walls with thicker portions defining a rib configuration, injecting a pressurized fluid throughout the rib configuration to displace molten material therein and to form a hollow channel therein, cooling the container being mold removing the molded container from the mold and cutting through the hollow channel at two spaced locations to form inlet and outlet openings to the channel to thereby enable circulation of a fluid through the channel.
