Description
BACKGROUND OF THE INVENTION
1. The Field of the Invention

The present invention relates to bins for use in storing, moving, processing and/or dispensing fluids.


2. The Relevant Technology

The biopharmaceutical industry uses large quantities of different types of fluids in their research, testing, and production of final product. Examples of such fluids include media, buffers, and reagents. Critical to the biopharmaceutical industry is the ability to easily transport, process, and dispense such fluids while preventing unwanted contamination. Historically such fluids have been held in stainless steel containers which required cleaning and sterilization between uses. To avoid the burden of repeated tank cleaning, current approaches to the storage and dispensing of fluids have utilized fluid dispensing bins.


Conventional fluid dispensing bins comprise an open top bin having a fixed floor with a fixed porthole extending therethrough. A disposable bag having a fluid line extending therefrom is disposed within the bin so that the fluid line extends out of the porthole. The disposable bag can be pre-sterilized so as to prevent contamination of fluids that pass there-through. Once the bag is filled with fluid, the bag provides a ready supply of the fluid for desired processing. Once the bag is empty, the bag can be replaced with a new bag without cleaning.


Although conventional fluid dispensing bins are useful, they have a number of shortcomings. For example, conventional fluid dispensing bins have a fixed floor with a fixed porthole configuration so that the customer is required to purchase from the bin manufacturer the corresponding bag that is designed to fit the bin. As a result, customers are limited in their ability to purchase bags from other producers in that the bags may not fit properly within the bin. Furthermore, due to the fixed nature of the bins, customers are unable to request customized bag designs that may be more useful under different processing or dispensing conditions. In addition, bags are often preassembled and then sterilized with other structures such as filters. However, once a filter or other structure is secured to the fluid line extending from a bag, the bag can no longer be used with the bin in that the filter cannot be passed through the fixed port hole on the floor of the bin.


Accordingly, there is an ongoing need in the art for fluid dispensing bins that can be easily used with a broad range of bag designs and bag assemblies.


The biopharmaceutical industry has been increasingly using disposable media bags for product processing. The media bags, being filled with liquid, require a media bag holder to contain the filled media bag. The media bags may have a combination of top and bottom tubing in various quantities and configurations. The bottom tubing requires a means of passing through the bottom of the bag holder and being held in place. One prior method to accommodate media bag tubing is to provide fixed holes in the bottom of the bag holder with either no retaining device or simple clamping type devices in line with the holes underneath the bottom of the bag holder.


Another method is two movable bottom pieces, each with one half of the required hole, which when brought together clamp onto the media bag tubing. Fixed holes in the bottom of the media bag holder allow for only one configuration of media bag tubing, both size of tubing and position. The clamping devices must be placed on the bottom of the bag holder which requires reaching underneath the bag holder, which may only be inches off the floor, making it difficult to see and access.


Two movable bottom pieces do allow changing of pieces to accommodate various tubing configurations, but require locking devices which must also be placed on the bottom of the bag holder and are often difficult to see and access.


BRIEF SUMMARY

Described herein are embodiments of a fluid line retainer that centralizes the ports during deployment of the bag and secures them in place such that they function properly once the bag is deployed. When draining, the placement of the ports affects the ability of the bag to drain properly. The bottom of the bin slopes toward the front and the ports are at the front of the bins and are held in place by the port holders. The port holders may have multiple design options. One embodiment is a ‘pinball’-style design that has springs to automatically adjust to the size of tubing that is placed into the port holder. Other embodiments include a screw-style design and a cover-style design. The screw-style and pinball-style designs may adjust from 1.5″ tubing and smaller, whereas the cover-style design may just hold the tubing in place.
