Disposable rolling diaphragm filling unit
First Claim
1. A filling unit for transporting a material from a source to a container comprising:
- a housing having a base and a head mounted on said base;
a flexible rolling diaphragm fixedly attached to said head and positioned to abut said base in a releasable sealable manner to define between said diaphragm and said head a working chamber in said housing;
drive means within said base for reciprocating said diaphragm;
port means on said head for providing material intake and discharge ports for said working chamber; and
said head with fixedly attached diaphragm and port means forming an integral module removable as a unit from said base without detachment of the diaphragm.

Abstract
The head, rolling diaphragm, intake and discharge ports form a single module, separate and easily removable from the principle cylinder of a rolling diaphragm filling unit. The rolling diaphragm may be fixed or removably attached to the head. Intake and discharge valves of various types may be mounted directly in the head, or may be mounted remote to the head module and fluidly connected directly to the head by tubing. Flanges of the rolling diaphragm provide an air and liquid tight seal between the head and base and removably attached to the head so as to facilitate visual inspection of the product contact surfaces of the head cavity prior to clamping the head module to the base.

41. A method of preparing a filling unit, including a diaphragm secured between and abutting a base and a head, for a new material comprising the steps of:
-
removing a first head module, having a first diaphragm fixedly attached to a first head and first intake and discharge ports on stud first head, from said base without detachment of the diaphragm from the first head; and removably attaching a second head module, having a second diaphragm fixedly attached to a second head and second intake and discharge ports on said second head, to said base. - View Dependent Claims (42, 43)

44. A module for use with and to be removably attached by a first clamping means to a base of a filling unit which transports material from a source to a container, said module comprising:
-
a head; a flexible rolling diaphragm; a second clamping means for removably attaching said diaphragm to said head independent of said first clamping means to define between said diaphragm and said head a working chamber; port means on said head for providing material intake and discharge ports for said working chamber; and said head with fixedly attached diaphragm and port means forming an integral module attachable and removable as a unit from said base without detachment of the diaphragm.
