Abstract
Abstract An inflatable pouch for packaging a circuit board is formed from two superposed sheets of an electrostatically dissipative plastic. The plastic sheets are welded together to form two air chambers therebetween, each having a plurality of passages therein and they are folded over along a transverse centerline so as to form a bottom end along the centerline, an open end opposite the bottom end and opposing front and rear walls. The side portions of the front and rear walls are welded together to form the side edges of the pouch. The passages in the front wall adjacent the open end of the pouch include enlarged portions which are transversely offset from and interengageable with corresponding enlarged portions in the rear wall to prevent a circuit board from sliding out the top of the pouch. Both air chambers are inflatable through a single inlet aperture which is sealable with a clamp.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
153 words
An inflatable pouch comprising: two superposed flexible plastic sheets which are welded together to form first and second air chambers therebetween, said first and second air chambers each including a plurality of parallel passages which are bounded by spaced weld lines in said sheets and a respective inlet portion for inflating said respective chamber, said plastic sheets having a transverse centerline and being folded over at said centerline so as to form a bottom end along said centerline, an open top end opposite said bottom end and opposing front and rear walls, said front and rear walls having adjacent side portions which are welded together to form side edges, said parallel passages in said first and second air chambers being arranged so that adjacent passages in said front wall and adjacent passages in said rear wall comprise alternating sections of said first and second air chambers; and means for sealing said inlet portions.
Claim 2
Dependent Claim
153 words
An inflatable pouch comprising: two superposed flexible plastic sheets which are welded together to form first and second air chambers therebetween, said first and second air chambers each including a plurality of parallel passages which are bounded by spaced weld lines in said sheets and a respective inlet portion for inflating said respective chamber, said plastic sheets having a transverse centerline and being folded over at said centerline so as to form a bottom end along said centerline, an open top end opposite said bottom end and opposing front and rear walls, said front and rear walls having adjacent side portions which are welded together to form side edges, said parallel passages in said first and second air chambers being arranged so that adjacent passages in said front wall and adjacent passages in said rear wall comprise alternating sections of said first and second air chambers; and means for sealing said inlet portions.
Claim 3
Dependent Claim
44 words
In the inflatable pouch of claim 1, said first and second air chambers being separated by an angled weld line which extends from said front wall across said centerline to said rear wall, said angled weld line intersecting said centerline at a midpoint thereof.
Claim 4
Dependent Claim
128 words
An inflatable pouch comprising: two superposed flexible plastic sheets which are welded together to form an air chamber therebetween and an inlet portion for inflating said air chamber, said air chamber including a plurality of passages which are bounded by spaced weld lines in said sheets, said plastic sheets having a transverse centerline and being folded over at said centerline so as to form a bottom end along said centerline, an open top end opposite said bottom end and opposing front and rear walls of said pouch, said front and rear walls having adjacent side portions which are welded together to form side edges of said pouch; and means for sealing said inlet portion, said plastic sheets comprising a polyurethane alloy which is operative for dissipating electrostatic charges.
Claim 5
Dependent Claim
128 words
An inflatable pouch comprising: two superposed flexible plastic sheets which are welded together to form an air chamber therebetween and an inlet portion for inflating said air chamber, said air chamber including a plurality of passages which are bounded by spaced weld lines in said sheets, said plastic sheets having a transverse centerline and being folded over at said centerline so as to form a bottom end along said centerline, an open top end opposite said bottom end and opposing front and rear walls of said pouch, said front and rear walls having adjacent side portions which are welded together to form side edges of said pouch; and means for sealing said inlet portion, said plastic sheets comprising a polyurethane alloy which is operative for dissipating electrostatic charges.
Claim 6
Dependent Claim
115 words
An inflatable pouch comprising: two superposed flexible plastic sheets which are welded together to form an air chamber therebetween and an inlet portion for inflating said air chamber, said air chamber including a plurality of passages which are bounded by spaced weld lines in said sheets, said plastic sheets having a transverse centerline and being folded over at said centerline so as to form a bottom end along said centerline, an open top end opposite said bottom end and opposing front and rear walls of said pouch, said front and rear walls having adjacent side portions which are welded together to form side edges of said pouch; and clamp means for sealing said inlet portion.
Claim 7
Dependent Claim
115 words
