Patent number: 6074095Abstract: A valve assembly for a satchel end tubular bag comprising four members. Two members form an upper sub-assembly and two other members for a lower sub-assembly. The valve assembly is adhesively secured at a corner tuck of the satchel end within the paper plies of the bag. The upper sub-assembly is wrapped within the lower sub-assembly and forms a passageway for a product injection nozzle to be inserted therethrough for introducing product into the bag. The members of the sub-assemblies are laterally offset and each sub-assembly has said members both laterally and longitudinally offset, or stepped, to achieve strength and a sift-proof construction. Extensions of one of the members of each sub-assembly extend bag-inwardly and comprise a thin pliable material, whereby to provide improved self-closure as the product fills the bag. Both improved filling and sealing are achieved.Type: GrantFiled: February 16, 1999Date of Patent: June 13, 2000Assignee: Bemis Company, Inc.Inventors: Roger Bannister, John D. Aiken, Michael A. Berry

Patent number: 5775388Abstract: A valve bag spout is mountable to a bag filling machine for being extended into the valve sleeve to discharge product into the valve bag. The maximum peripheral dimension of the spout filling tube is much smaller than the inner peripheral dimension of the valve sleeve while a wing assembly is mounted to the filling tube to have its wings extend outwardly of diametrically opposite sides of the filling tube in symmetrical relationship to the filling tube central axis. The wings diverge horizontally transversely outwardly in a rearward direction from the spout front discharge end portion. The front end of the wing assembly is circular while in a rearward direction gradually transitions to a flattened elliptical shape. The maximum height of the wing assembly is only slightly greater than the outer diameter of the filling tube and is much smaller than its maximum transverse horizontal dimension.Type: GrantFiled: March 24, 1997Date of Patent: July 7, 1998Assignee: Bemis Company, Inc.Inventors: Richard J.

Patent number: 5281027Abstract: A tubular bag blank has a plurality of outer contiguous non-heat sealable plies and an inner heat sealable plastic ply. All of the plies in the tubular blank are bonded together circumferentially around an open top end of the bag and are closed at the bottom end where only the non-heat sealable plies are bonded together. The inner heat sealable ply is freely folded and fully detachable in a non-adhesive manner at the bottom end of the bag. The inner plastic ply being heat sealable to closure at both bag ends. Upon heat sealing the bottom end, a plastic pouch is formed by the inner ply which may be heat sealed to closure at the open end when filled with a product or commodity and may be optionally severed thereat by compressive heat and pressure applied to the outer non-heat sealable plies. When fully packed, the outer paper plies may be stripped away leaving a sealed plastic pouch with the packaged contents therein ready for use by the purchaser.Type: GrantFiled: May 26, 1993Date of Patent: January 25, 1994Assignee: Bemis Company, Inc.Inventor: Ronald G.
