Apparatus, method and flexible bag for use in manufacturing
First Claim
1. A method of automatically filling receiving members with a fluent material for mass production of filled receiving members, the method comprising the steps of:
- providing an array of receiving members adapted to receive fluent material;
providing a flexible bag containing fluent material; and
metering a charge of fluent material from the bag to plural ones of the receiving members at the same time.

Abstract
A method for manufacturing in which a fluent material is dispensed to an article such as a container from a flexible bag The fluent material is dispensed directly to the container without any intervening structure which contacts the fluent material. Accordingly, the apparatus can be constructed of less expensive materials and does not require frequent cleaning. The apparatus acts on the bag to dispense and does not act on the fluent material. Thus, the apparatus has particular application where aseptic conditions need to be maintained such as in the packaging of the food and medicine The flexible bag is preferably formed with multiple outlets permitting simultaneous dispensing to multiple containers.

16. A method of dispensing a fluent material to articles which receive the fluent material in a manufacturing operation comprising the steps of:
-
selectively dispensing fluent material to plural ones of the articles at the same time by deforming a flexible reservoir to eject fluent material therefrom; and
replacing the flexible reservoir with another flexible reservoir upon substantial depletion of fluent material from the reservoir as a result of the dispensing step, for continued dispensing of the fluent material. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)
forming the flexible reservoir;
filling the flexible reservoir with the fluent material;
sealing the reservoir.

-
18. A method as set forth in claim 17 wherein the step of filling the flexible reservoir is carried out in an aseptic environment.
-
19. A method as set forth in claim 17 further comprising sterilizing the reservoir and fluent material after said filling step.
-
20. A method as set forth in claim 17 wherein subsequent to the sealing step and prior to the step of selectively dispensing fluent material, the method further comprises transporting the sealed reservoir to a different manufacturing facility.
-
21. A method as set forth in claim 17 further comprising forming multiple outlets in the sealed reservoir for dispensing fluent material and wherein the step of dispensing includes independently deforming the flexible reservoir in regions adjacent the outlets.
-
22. A method as set forth in claim 21 further comprising squeezing the reservoir to force fluent material toward the regions adjacent the outlets.
-
23. A method as set forth in claim 16 wherein the step of dispensing fluent material further comprises dispensing fluent material to the articles in at least one of different rates and different quantities.
-
24. A method as set forth in claim 16 wherein the step of dispensing comprises metering a fixed amount of fluent material to the articles.
-
25. A method as set forth in claim 16 further comprising the steps of obtaining relative movement between the flexible reservoir of the fluent material and the articles to which the fluent material is to be dispensed whereby with respect to the reference frame of the flexible reservoir, the articles pass under the reservoir.
-
26. A method of automatically filling receiving members with a fluent material for mass production of filled receiving members, the method comprising the steps of:
-
providing an array of receiving members adapted to receive fluent material;
providing a flexible bag having multiple outlets and containing fluent material;
metering a charge of fluent material from the bag to plural ones of the receiving members. - View Dependent Claims (27, 28, 29)
