Abstract
Abstract Apparatus and processes for handling, filling and sealing a pouch in an aseptic environment include a pouch carrier and upper pouch grippers for holding the pouch during sterilization, filling and sealing. Vacuum jaws in an aseptic chamber engage, stretch and open the pouch, and a cutter cuts off a removable pouch seal before the pouch is opened. Once opened, the pouch is filled, then closed, sealed and moved out of the chamber through the bath.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
200 words
In combination, filling means, and apparatus for engaging, opening and closing a flexible walled pouch to be filled by said filling means, wherein said apparatus comprises: two opposed vacuum jaw means including normally curved resilient porous members disposed opposite and spaced from one another and having respective adjacent ends; a stretching foot means disposed proximate each end of each said resilient member, each said foot means being disposed adjacent and spaced from the foot means of said opposed resilient member such that said respective opposed foot means at each end of the resilient members are closer to each other than are central portions of said normally curved resilient members; said respective opposed foot means being normally spaced apart for receiving a pouch therebetween; both said vacuum jaw means being mounted for motion toward and away from each other for engaging and stretching a pouch; and said foot means, upon converging motion of said opposed jaw means, for engaging a pouch before said resilient members engage said pouch, said opposed foot means at adjacent ends of said resilient members being operable to move away from opposed foot means at other adjacent ends of said resilient members to stretch said pouch therebetween.
Claim 2
Dependent Claim
200 words
In combination, filling means, and apparatus for engaging, opening and closing a flexible walled pouch to be filled by said filling means, wherein said apparatus comprises: two opposed vacuum jaw means including normally curved resilient porous members disposed opposite and spaced from one another and having respective adjacent ends; a stretching foot means disposed proximate each end of each said resilient member, each said foot means being disposed adjacent and spaced from the foot means of said opposed resilient member such that said respective opposed foot means at each end of the resilient members are closer to each other than are central portions of said normally curved resilient members; said respective opposed foot means being normally spaced apart for receiving a pouch therebetween; both said vacuum jaw means being mounted for motion toward and away from each other for engaging and stretching a pouch; and said foot means, upon converging motion of said opposed jaw means, for engaging a pouch before said resilient members engage said pouch, said opposed foot means at adjacent ends of said resilient members being operable to move away from opposed foot means at other adjacent ends of said resilient members to stretch said pouch therebetween.
Claim 3
Dependent Claim
43 words
Apparatus as in claim 1 wherein said foot means are operable to engage and pinch said pouch, stretch said pouch, and slide on said pouch in opposed directions as said resilient members flatten upon motion toward each other during engagement with said pouch.
Claim 4
Dependent Claim
16 words
Apparatus as in claim 2 including means for applying a vacuum to said resilient porous members.
Claim 5
Dependent Claim
37 words
Apparatus as in claim 3 wherein during application of said vacuum adjacent said pouch mouth said resilient members are operable to return to curved disposition upon motion away from each other to thereby open said pouch mouth.
Claim 6
Dependent Claim
44 words
Apparatus as in claim 1 wherein said foot means each have initial pouch engaging surfaces thereon substantially parallel to said pouch upon initial engagement therewith, said initial pouch engaging surfaces tapering away from said pouch when said resilient members lie flat against said pouch.
Claim 7
Dependent Claim
128 words
Apparatus for engaging, stretching, opening and closing a flexible pouch having opposed side walls, for filling said pouch, said apparatus comprising: two opposed vacuum jaws; each jaw comprising a resilient normally curved porous element; each jaw element having two initial pouch engaging ends spaced from and opposite initial pouch engaging ends of the opposed jaw element such that said opposed ends are disposed closer to each other than are the central respective portions of said jaw elements; and means operable to move said elements and pouch engaging ends toward each other to engage a pouch, with said initial ends engaging said pouch, moving apart, and stretching said pouch side walls into a flattened condition as said curved resilient jaw elements straighten into engagement with said pouch side walls.
Claim 8
Dependent Claim
128 words
Apparatus for engaging, stretching, opening and closing a flexible pouch having opposed side walls, for filling said pouch, said apparatus comprising: two opposed vacuum jaws; each jaw comprising a resilient normally curved porous element; each jaw element having two initial pouch engaging ends spaced from and opposite initial pouch engaging ends of the opposed jaw element such that said opposed ends are disposed closer to each other than are the central respective portions of said jaw elements; and means operable to move said elements and pouch engaging ends toward each other to engage a pouch, with said initial ends engaging said pouch, moving apart, and stretching said pouch side walls into a flattened condition as said curved resilient jaw elements straighten into engagement with said pouch side walls.
Claim 9
Dependent Claim
49 words
Apparatus as in claim 6 wherein each said jaw element has a portion mounted on a vacuum plenum means, and further including respective resilient means for securing said initial pouch engaging ends of said jaw elements to said plenum means for movement with respect to said plenum mounted portion.
Claim 10
Dependent Claim
40 words
Apparatus as in claim 7 wherein said initial pouch engaging ends comprise feet means mounted on said resilient means for pivotal motion relative thereto and operable to stretch said pouch as said jaw elements are moved inwardly toward said pouch.
Claim 11
Dependent Claim
23 words
Apparatus as in claim 8 wherein said jaw elements are elongated from end to end and include passageways for transmission of vacuum therethrough.
Claim 12
Dependent Claim
71 words
Apparatus as in claim 6 including means for applying a vacuum to said porous jaw elements and means for withdrawing said jaw elements away from each other, each said jaw element being operable to engage a respective pouch side wall and draw it away from an opposed side wall as said initial pouch engaging ends thereof move inwardly toward one another to relieve stretching bias on the associated said side wall.
Claim 13
Dependent Claim
23 words
Apparatus as in claim 6 wherein said initial pouch engaging ends comprise pouch engaging feet pivoted to said jaw elements at ends thereof.
Claim 14
Dependent Claim
32 words
Apparatus as in claim 11 wherein said feet on each end of a jaw element are disposed opposite feet on the other jaw and pouch engaging nips are formed between opposing feet.
Claim 15
Dependent Claim
37 words
Apparatus as in claim 12 wherein each of said feet pivots outwardly from said jaw elements when engaging a pouch, said respective nips moving in an outward direction and apart from each other to stretch said pouch.
Claim 16
Dependent Claim
24 words
Apparatus as in claim 13 wherein said feet slide on said pouch side walls in an outward direction thereby stretching said pouch side walls.
Claim 17
Dependent Claim
65 words
Apparatus as in claim 7 wherein said resilient means comprise respective springs mounted between ends of said jaw elements and said plenum mounted portion, said springs collapsing upon engagement of said pouch engaging ends with a pouch and constantly urging said pouch engaging ends in a direction toward an opposed jaw element such that said elements are normally curved upon initial engagement with a pouch.
