ABSTRACT:
Method of producing a moulded bottle having means which determines the relationship between the bottle body and the annular position of the finish thereof or associated means, such as a closure cap, pouring spout, delivery pump, or any other desired appurtenance, that is mountable upon the finish of the blown bottle in a predetermined annular position. This method may include moulding a parison in a blank mould and forming thereon a finish that has at least one guidance indexing means, i.e., physically engageable orientation guidance means, and transferring the parison from the blank mould to a forming mould which has a moulding cavity that is of a shape to produce the hollow bottle in its desired form. This forming mould may be a blow mould that has at a particular annular orientation determining point at least one other guidance indexing means complementary to that of the finish, i.e., complementary guidance means, so that by transferring the parison and its finish to the blow mould the complementary finish and blow mould indexing or orientation guidance means may be interengaged and the parison blown in the blow mould cavity into a hollow bottle body having the desired annular orientation relative to the finish. Practice of this method makes possible and reliable the ready production of such formed bottle and the relative orientation of its finish and body, or the oriented removable mount upon its finish of any such associated means. For example, a blown bottle having a non-round body may have mounted on its finish by a simple anchoring procedure a non-round cap whereby the transverse shapes of such body and cap will have a desired predetermined orientation relationship.
