Patent number: 7381559Abstract: A container is provided for cell growth by artificial cultivation of selected biological material in a growth liquid for use in an oscillating incubator. The container has a circular bottom with rounded corners joining a sidewall that is inclined at an angle toward a longitudinal axis of the container to define a container volume. The bottom has six equally spaced baffles extending inward from the corners and upward toward a large diameter opening of the container centered on the longitudinal axis. The baffles have a triangular cross-sectional shape with an included angle of about 28–40°, and a height measured parallel to the longitudinal axis of about 15–25% of the usable container volume. The baffles end before the longitudinal axis. The container and baffles are blow molded of a polymer suitable for blow molding. An air permeable filter is placed over the container opening, with the filter having an adhesive on one side to stick to the container.Type: GrantFiled: June 9, 2004Date of Patent: June 3, 2008Assignee: Scientific Plastic Products, Inc.Inventors: Samuel A.

Patent number: 5848735Abstract: A shell for a water cooler has two side sections and a front section. The side sections slide-connect with the front section and lock in place at corner joints, thereby forming an essentially one-piece shell. The shell may be economically fabricated with only two molds (one for the side sections and one for the front section) and with only the slide-connect step.Type: GrantFiled: September 30, 1996Date of Patent: December 15, 1998Assignee: Kel-Jac Engineering and Plastic Sales, Inc.Inventors: John W.
