Abstract

A multilayer container including an outer relatively rigid plastic layer having a body portion, a finish defining an opening and a base having an atmospheric vent opening therethrough. The container includes an inner flexible plastic layer of relative thin flexible material throughout which does not adhere to the outer plastic layer. The inner flexible layer has a closed bottom portion engaging the inner surface of the finish of the outer plastic layer and a radially extending flange portion of the inner layer overlying the finish of the outer layer. The outer layer preferably comprises an olefin and the inner layer preferably comprises amorphous nylon. The method of making the multilayer container includes coextruding a parison comprising the relatively thick outer layer of plastic material and the relatively thin inner layer of plastic material, closing molds about the parison, blow molding the parison to form the outer rigid plastic layer having a body portion, the finish defining an opening, and the base and the inner flexible layer of relatively thin flexible material.
