POLYMERIC MATERIAL FOR CONTAINER
20170239874 · 2017-08-24 ·

A vessel is configured to hold a product in an interior region formed in the vessel. 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.

Telescoping fill station shroud for a blow/fill/seal packaging machine

In a blow/fill/seal packaging machine, aseptic environment is provided by a telescoping fill station shroud through which a sterile curtain gas flows. The telescoping fill station shroud includes an open-ended lower sleeve, an open-ended upper sleeve slidably coacting with the open-ended lower sleeve, and a manifold plate mounted over a proximal end portion of the upper sleeve.

Gas-assisted base blow off methods for blow molding applications
10875230 · 2020-12-29 · ·

This disclosure provides a method of manufacturing a polymer container according to a blow molding or stretch blow molding process, in which the base of the blow mold has at least one orifice for pressurized gas to enter the blow mold through the base. Introducing pressurized gas through the orifice in the blow mold base provides cooling assistance within the gas mold, much earlier than the cooling using conventional methods, which can reduce or eliminate the need for any post mold cooling. This method has been found to be applicable to non-hot fill application bottle and container manufacture.

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.

Methods for aseptic packaging of low-acid foods
10543944 · 2020-01-28 · ·

The present disclosure relates to methods of maintaining sterility of an aseptic work zone of a blow-fill seal operation so that low acid foods may be aseptically processed and packaged. The methods of the present disclosure further provide for maintain the sterility of the aseptic work zone such that the aseptic work zone does not have to be enclosed in a separate sterile environment during the blow fill seal process. The methods of the present disclosure further provide a sterilization procedure that is compliant with FDA regulations related to the aseptic packaging of low acid food products. Further disclosed, are methods for producing a hermetically sealed container containing a low acid food product.
