A method of preparing a collapsible bag includes providing the bag in a collapsed configuration and filling it. The bag has a spout connected to a flexible mounting. A portion of the mounting is flat within the bag in the same plane as the spout and can form an angle between 0 and 180 degrees with the spout's plane. The mounting includes a peripheral ring in the spout having flexible legs. The legs permit the evacuation members to be displaced relative to the ring to accommodate a service line connector. The evacuation members can be helical channels, are integral with the mounting, and are as flat as possible within the bag upon manufacture. Each member is adjustable to alternative positions where it is oriented radially, perpendicularly, or at an angle between relative to the plane of the ring, without the flexing of the flexible legs or the evacuation members.

1. A method of preparing a collapsible bag for evacuation of a liquid therein, the method comprising: providing the collapsible bag in a collapsed configuration, the collapsible bag having a spout and a flexible mounting connected the spout, at least a portion of the flexible mounting being disposed within the collapsible bag in a flat configuration in substantially the same plane in which the spout lies; andfilling the collapsible bag with the liquid, such that the collapsible bag is in a filled configuration, such that at least the portion of the flexible mounting in the flat orientation is moved into an extended configuration in a plane that forms an angle of between about 0 degrees and about 180 degrees with the plane in which the spout lies,wherein the flexible mounting comprises: a peripheral ring adapted to fit within a spout of said fitment; a plurality of flexible legs attached to the peripheral ring to which are attached evacuation members for evacuation of said bag that permit said evacuation members to be displaced relative to said peripheral ring to allow accommodation of any service line connector to which said fitment is secured without interfering with the operation of said evacuation members and said evacuation members being as flat as possible within the bag upon manufacture and wherein said evacuation members are integrally formed with said flexible mounting and at least one of said evacuation members is a helical channel,wherein each of said evacuation members being individually adjustable to alternative positions where the longitudinal axis of the evacuation members is oriented radially (0 degree), perpendicularly (90 degree), or at an angle selected from the range of from about 0 degree to about 90 degree to the plane of the peripheral ring, without the flexing of the flexible legs or the evacuation members. 2. The method of claim 1, further comprising the step of evacuating the liquid from the collapsible bag. 3. The method of claim 2, wherein after the liquid has been evacuated, at least the portion of the flexible mounting in the expanded configuration moves back to the flat configuration. 4. A flexible mounting according to claim 1, wherein said at least one evacuation member is made from tubular netting. 5. A flexible mounting according to claim 1, wherein the number of said evacuation members are attached to said peripheral ring is selected from the range of from 2 to 20, and wherein said evacuation members are symmetrically or asymmetrically mounted to the peripheral ring. 6. A flexible mounting according to claim 5, wherein at least one of said plurality of evacuation members is of different length from the remaining evacuation members of said plurality of evacuation members. 7. A flexible mounting according to claim 6, wherein said at least one evacuation member is a tubular attachment portion located at one end thereof for snap fit connection to the central member. 8. A method of preparing a collapsible bag for evacuation of a liquid therein, the method comprising: providing the collapsible bag in a collapsed configuration, the collapsible bag having a spout and a flexible mounting connected the spout, at least a portion of the flexible mounting being disposed within the collapsible bag in a flat configuration in substantially the same plane in which the spout lies; andfilling the collapsible bag with the liquid, such that the collapsible bag is in a filled configuration, such that at least the portion of the flexible mounting in the flat orientation is moved into an extended configuration in a plane that forms an angle of between about 0 degrees and about 180 degrees with the plane in which the spout lies,wherein the flexible mounting comprises: a peripheral ring adapted to fit within a spout of said fitment; a plurality of flexible legs attached to the peripheral ring to which are attached evacuation members for evacuation of said bag that permit said helical evacuation members to be displaced relative to said peripheral ring to allow accommodation of any service line connector to which said fitment is secured without interfering with the operation of said evacuation members and said evacuation members being as flat as possible within the bag upon manufacture and wherein said evacuation members are integrally formed with said flexible mounting and at least one of said evacuation members is a helical channel;wherein each of said evacuation members being individually adjustable to alternative positions where the longitudinal axis of the evacuation members is oriented radially (0 degree), perpendicularly (90 degree), or at an angle selected from the range of from about 0 degree to about 90 degree to the plane of the peripheral ring, without the flexing of the flexible legs or the evacuation members anda central member to which a second evacuation member is secured; and a plurality of spring members extending between said peripheral ring and said central member, said spring members supporting said central member while permitting said central member to be displaced relative to said peripheral ring; wherein the plurality of spring members permits the displacement of the central member relative to said peripheral ring and wherein the spout having an internal passage that does not hinder insertion of couplings into the bag. 9. A dispenser for dispensing a fluid, the dispenser comprising: a collapsible bag having a fitment, the fitment having a spout defining a passage to an interior of the collapsible bag; anda flexible mounting for securing a plurality of flexible evacuation members to the fitment for use in the collapsible bag said mounting consisting of: a peripheral ring adapted to fit within the spout of said fitment; a plurality of flexible legs attached to the peripheral ring to which is attached said evacuation members for evacuation of said collapsible bag that permit said evacuation members to be displaced relative to said peripheral ring to allow accommodation of any service line connector to which said fitment is secured without interfering with the operation of said evacuation members and said evacuation members being as flat as possible within the collapsible bag upon manufacture and wherein said evacuation members are integrally formed with said flexible mounting and at least one of said evacuation members is a helical channel;wherein each of said evacuation members being individually adjustable to alternative positions where the longitudinal axis of the evacuation members is oriented radially (0 degree), perpendicularly (90 degree), or at an angle selected from the range of from about 0 degree to about 90 degree to the plane of the peripheral ring, without the flexing of the flexible legs or the evacuation members. 10.
