Connection-Free Filter Capsule Apparatus

摘要

Disclosed is a tube/tube connector/capsule port assembly that eliminates a connection point in a filter capsule apparatus. A relatively soft tube is thermally or sonically bonded to a relatively hard tube connector that may have a tube receiving bore, frustoconical tube receiving channel or straight tube receiving channel. The tube connector is bonded to a filter capsule port. The manufacturing process can be either a one-step process bonding the tube, tube connector and capsule in one step, or a two-step process that binds the tube to the tube connector in the first step and they binds the tube/tube connector subassembly to a filter capsule housing during the housing's molding procedure. Single and dual-walled tubes may be used as well as single and dual-walled tubes having reinforcing material superposed about or embedded in the tube wall(s). A tube support collar is also disclosed.

主权项

1. A filter capsule-tube assembly comprising:
a shell having a housing wall defining a filter chamber with at least one port defining a port channel formed on the shell that defines a channel in fluid communication with the filter chamber; a rigid tube connector defining a connector bore and having portions defining, a tube receiving bore and portions defining a capsule port receiving bore, wherein the tube connector is secured to the at least one port via the port receiving bore; and, a flexible tube defining a lumen bonded to the tube connector with an end of the tube secured in the tube receiving bore, wherein the connector bore, tube lumen, port bore are in fluid communication.
