Abstract: A hollow vacuum packaging product in which a ring includes threads distributed around its periphery, and between which a sealing cap enters into engagement when the hollow product is opened/closed. In an evacuated closed condition of the hollow product, the sealing cap is configured to enter into engagement only in an interval between two consecutive threads, or in plural such consecutive intervals, but not in all of the intervals. Such a hollow product may be, as an example, a thermoplastic bottle or jar.

Abstract: A process of manufacturing a hollow glass product with an offset collar axis, including the steps of inserting molten material into a cavity of a roughing mold, allowing the molten material to penetrate into a bottom portion of the roughing mold, perforating a collar by moving a punch into the bottom portion of the roughing mold along a non-vertical axis, extracting the punch from the bottom portion of the roughing mold, thereby completing processes of shaping the molten material into a blank, transferring the blank into a finishing mold by turning over the blank 180° with respect to a horizontal axis, and blowing the blank through the collar in the finishing mold such that the blank shapes into a hollow glass product. The cavity includes at least one input section which is substantially vertical.
