Embodiment Construction

[0035] figure 2 A first embodiment of the invention is shown. Where the same features are used in the figures, the same element numbers are used. The fitting 30 of the present invention is made of a flexible, compressible, resilient plastic material. Preferably, fitting 30 is made of a plastic material capable of being bonded to bag 12 in the same manner as the conventional rigid plastic fitting of FIG. 1 . As with this and all other embodiments of the invention, the fitting may alternatively be formed of other materials and held in a liquid-tight seal to the bag by other means such as adhesives or mechanical means such as threaded portions and nuts. As shown, a pinch valve 18 is located on the neck 6 of the fitting between the bag 12 and the barbed portion 8 . In this embodiment the fitting has a flange 4 sealed to the bag 12 . As shown, the fitting 30 has a flange 4 inside the bag 12 . It can likewise be attached to the outer surface of the bag 12 if desired. Neck 6 is...

Abstract

A device for reducing or eliminating the dead space in a fitting and tubing used on a disposable container by using a flexible elastic fitting that can accommodate a pinch valve or a clamp or the like closer to the flange portion of the fitting. The fitting is formed of a flange and a neck portion with a bore running through them. The neck may terminate in either a tubular section or a hose barb. The neck end section especially when in the form of a hose barb can be reinforced to provide a platform for attaching a tubing to it.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 61 / 341,169, filed March 26, 2010, which is hereby incorporated by reference in its entirety. technical field [0003] The invention relates to a fitting for a container. More specifically, it relates to a flexible fitting capable of sealing a constriction with little or no dead volume. Background technique [0004] Bag-type flexible containers are used in various industries today including food, beverage, medical, chemical, and pharmaceutical and biopharmaceutical industries. They offer advantages over traditional rigid containers for handling and storing products and single-use intermediates, thereby eliminating the need for cleaning, allowing for more flexible and variable production lines, as they can be connected to different components as required, Unlike conventional dedicated stainless steel production lines, and can be pre-sterilized such a...
