Weld seams of parisons formed in an inert atmosphere during extrusion followed by blow molding with a blowing gas containing an oxidizing agent are extremely strong when compared with conventional seams formed in the presence of air. By sealing in an inert atmosphere and subsequently blowing the parison with a mixture of nitrogen and fluorine, a container is produced having both high weld seam str...

The invention relates to an automatic syringe for injecting two or more different injection liquids which may not be in contact with each other for long periods of time. For that purpose, the ampoule between the piston and the needle connection includes one or more stoppers which keep the injection liquids separated from each other, while at a point a short distance before the needle connection a ...

A vapor-tight package has a deposit comprising nonmetallic, microwave-absorbing particles such as graphite dispersed in nonmetallic binder. When heated in a microwave oven, heat built up in the particles may soften and weaken the underlying packaging material, thus venting the package. When the deposit itself is impervious to vapors, it can be positioned over an opening in the package, and the hea...
