Abstract:
A liquid dispenser (7) uses a flexible bag (9) having expansible and collapsible cells (61). A rigid manifold (95), and in one instance a rigid frame (602) is provided in the bag to keep passages open in use and to isolate one of the cells from the remaining cells. The dispenser employs an efficient and quiet air pressure operating system. In one application, a concentrated drink mix may be held in a reservoir and diluted within other cells in the bag for dispensing to a cup or the like. A valve system allows for the particulates in the liquid without compromising the function of the valve.
Abstract:
The present invention provides a method for preparing solventless bonds between plastic components. The method includes the step of using infrared exposure to create bonds, and more specifically, the step of exposing a first article and/or a second article to a specific portion of the infrared spectrum. The invention further provides medical devices fabricated using infrared exposure.

A liquid dispenser uses (1) a flexible bag (9) having expansible and collapsible cells (61, 65, 69, 73, 77). A rigid manifold (95) is provided in the bag to keep passages open in use and to isolate one of the cells from the remaining cells. In one application, a concentrated drink mix may be held in a reservoir (61, 65)and diluted within other cells (73, 77) in the bag for dispensing to a cup (c) or the like. A valve system allows for the particulates in the liquid without compromising the function of the valve.
Abstract:
A multiple layer structure comprising a first and a second skin layer, each skin layer comprised of a polypropylene containing polymer, and a radio frequency ('RF') susceptible layer adhered to and between the first and second skin layers. The RF layer has a first component of a propylene based polymer, a second component of a non-propylene polyolefin, a third component of a radio frequency susceptible polymer, and a fourth component of a polymeric compatibilizing agent.

Abstract:
A port and closure assembly for a container is provided. The port and closure assembly includes a port having a tubular portion that extends from a base and terminates at an end including an opening. The tubular portion is divided into an upper and lower section by a pierceable membrane. The upper section including an end that terminates at the opening and including a resealing injection site. A closure member for removably surrounding at least a portion of the end of the port including the opening is provided. The closure includes a sleeve that circumscribes at least a portion of an outer surface of the upper section of the tubular portion. The sleeve is so constructed and arranged as to cause portions of the upper section to contact the resealing member during a sterilization step that softens the portions and further causes the portions of the upper section to retain the resealing injection site within the tubular portion after the portions have hardened.
