Abstract: A vessel for culturing of cells is disclosed. The vessel is capable of exhausting substantially all liquid material from the vessel's internal volume through an outlet port. A flange incorporated with the outlet port is utilized as a flow diverter for removing liquid media from internal surfaces of the vessel. The flange also engages the vessel body so that the flow of a liquid medium is directed outward from the internal surfaces of the vessel through the outlet port. The top surface, flange base, and planar surfaces of the flange further assist to redirect surface tension of the fluid toward the port.

Abstract: A soft nonwoven web of entangled fibers or filaments having a pattern of fused bond areas and a stretched, loopy filament configuration outside of the patterned bond areas. The result is a soft web with high bulk that retains to a high degree the original bonded strength properties. In one embodiment, product may be obtained by pattern bonding a meltblown microfiber web under conditions of heat and pressure and then stretching the web under controlled conditions up to preferably about 140% of its original dimension in at least one direction. When relaxed, the stretched filaments bulk and loop except in the fused bond areas where they retain bonding properties. Preferred stretching conditions include room temperature and the use of draw rolls at speed differentials producing the desired stretch. Examples of thermoplastics polymers useful in accordance with the invention include polypropylene, polyethylene, polyesters and polyamides, as well as copolymers and polymer blends.
