A syringe containing a high water content product and for use in a drug infusion system is provided. The syringe includes a plunger carrying front and rear o-rings made of a diene rubber compound such as chlorobutyl rubber or bromobutyl rubber to impart very low gas permeability characteristics to the o-rings. The plunger may be molded as a single part or in two parts. If molded as one part with radially-engaging mold portions, the seal glands in the plunger may include parting lines from the mold. If molded as two parts with axially-engaging mold portions, the front seal gland may include a sealing surface and under cut that has no parting line. The o-rings may be surface treated with a lubricant to improve sealing where the molding process gives rise to parting lines in the seal glands.

Sealing arrangement for syringe

A sealable container () for flowable material formed with top () and flexible and stiffened bottom () walls joined by front (), rear (), and opposite side walls (). The top wall including an openable lid (D) formed with an improved scoop holder () and a collar () received about a finish () of the front, rear, and side walls. The flexible and stiffened bottom wall () includes at least one sagittal stiffening channel () and an optional transverse stiffening channel (). The openable lid includes a sealing wall () that cooperates with other improved container components to prevent spillage of the flowable material after the seal is peeled and removed.
