Method and apparatus for manufacturing multi-layer bottle |
摘要 |
A method and an apparatus for manufacturing a multi-layer bottle by discharging an inner layer parison from a multi-layer die head and pinching a lower portion of the inner layer parison by a pinch apparatus; discharging an outer layer parison which is longer than the inner layer parison; pinching the lower portion of the outer layer parison by a molding mold; and blow molding the inner layer parison. In such a manner, the multi-layer bottle is manufactured. When the multi-layer bottle having an inner layer separating function is manufactured, the inner layer parison and the outer layer parison comprise different resins having no adhesivity to each other.
