09896318 · 2018-02-20 · ·

A device for manufacturing and filling beverage containers (12) having thin walls and/or at least partially unstable shapes under the influence of heat is described, in which the containers (12) are manufactured by blow molding of preforms (10), then filled with a hot liquid filling product (16), next pressurized by a compressed gas (18), and then sealed. The preforms (10) and the containers (12) molded therefrom are pressurized during blow molding at a blow molding temperature, which is essentially below 110 C.

Multi-layer tube and process of making the same

A vessel is configured to hold a product in an interior region formed in the vessel. The vessel includes an inner layer arranged to define the interior region and an outer layer. The vessel is formed using a blow-molding process in which a multiple layer parison is blow molded to form the vessel. The multiple layer parison is formed in an extrusion process in which a number of extruders are arranged to co-extrude associated inner and outer parisons to establish the multiple layer parison.

MULTI STAGE RADIAL DEFORMATION FOR MANUFACTURING THIN STRUT STENT FROM BIOABSORBABLE POLYMER

This invention discloses a process for preparation of a balloon expandable biodegradable polymer stent with thin struts (strut thickness 130 m or less, preferably 100-110 m) with high fatigue and radial strength. The invention discloses a process for the preparation of a biodegradable polymer stent which involves radially deforming the biodegradable polymer tube by applying pressure to it with an inert gas at a predefined temperature in multiple stages with each successive stage having a pressure higher than the pressure applied in a previous stage. The process further involves maintaining the predefined temperature and pressure conditions of each stage for a specified time period after application of the pressure.
