Abstract
Abstract A transportation container (68,44) for transporting items or enclosures (72) requiring electrostatic protection includes a box (44) lined with electrically conductive bubble layer material (58) which protrudes from open seams (66) and which is also electrically accessible through an aperture (28) in registration with an opening (42) when the box (44) is contained within the sleeve (68). The accessibility of the electrically conducting bubble sheet material (58) allows for either deliberate discharge to ground potential of the bubble material (58) via the aperture (28) or provides ample opportunity for accidental discharge to ground by virtue of protrusion of the bubble material (58) through the open seams (66). The bubbles of the material (58) distort and burst to accommodate a range of enclosures from very small to quite large by virtue of the fact that the tips of the bubbles (62) just touch without compression when the box (44) is closed.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
149 words
A transportation container for electronic components comprising: an inner box having, as elements, a base, first and second sides, first and second ends, and a lid; said box being formed from a single planar sheet by folding; an electrically conductive, continuous, elastic layer on a surface of said planar sheet; said container further comprising a conforming outer sleeve for holding closed said box when said sheet is folded to form said box, said face of said sheet having said elastic layer forms the inside surface of said box; and where said layer deforms along abutting edges of said elements seals open seams between said elements to cause the interior of said box to be completely surrounded by electrically conductive material, wherein said layer is a bubble sheet with a flat side on said face of said sheet and a plurality of gas-filled bubbles protruding said face of said sheet.
Claim 2
Dependent Claim
149 words
A transportation container for electronic components comprising: an inner box having, as elements, a base, first and second sides, first and second ends, and a lid; said box being formed from a single planar sheet by folding; an electrically conductive, continuous, elastic layer on a surface of said planar sheet; said container further comprising a conforming outer sleeve for holding closed said box when said sheet is folded to form said box, said face of said sheet having said elastic layer forms the inside surface of said box; and where said layer deforms along abutting edges of said elements seals open seams between said elements to cause the interior of said box to be completely surrounded by electrically conductive material, wherein said layer is a bubble sheet with a flat side on said face of said sheet and a plurality of gas-filled bubbles protruding said face of said sheet.
Claim 3
Dependent Claim
38 words
A transportation container according to claim 1 where, when said box is closed with no enclosure therein, the surface of said layer on said lid is in uncompressed tangency with the surface of said layer on said base.
Claim 4
Dependent Claim
17 words
A transportation container according to claim 1 wherein bubbles can burst to accommodate prominences on any enclosure.
Claim 5
Dependent Claim
27 words
A transportation container according to claim 3 wherein said layer, at any open seam in said box, protrudes from the open seam to allow electrical contact therewith.
Claim 6
Dependent Claim
173 words
A transportation container for electronic components comprising: an inner box having, as elements, a base, first and second sides, first and second ends, and a lid; said box being formed from a single planar sheet by folding; an electrically conductive, continuous, elastic layer on a surface of said planar sheet; said container further comprising a conforming outer sleeve for holding closed said box when said sheet is folded to form said box, said face of said sheet having said elastic layer forms the inside surface of said box; and where said layer deforms along abutting edges of said elements seals open seams between said elements to cause the interior of said box to be completely surrounded by electrically conductive material, wherein said box has an aperture in said sheet allowing access to said layer, and wherein said sleeve has an aperture coming into registration with said aperture in said box when said box is in said sleeve; whereby said layer may have electrical contact made there-with when said box is in said sleeve.
Claim 7
Dependent Claim
173 words
A transportation container for electronic components comprising: an inner box having, as elements, a base, first and second sides, first and second ends, and a lid; said box being formed from a single planar sheet by folding; an electrically conductive, continuous, elastic layer on a surface of said planar sheet; said container further comprising a conforming outer sleeve for holding closed said box when said sheet is folded to form said box, said face of said sheet having said elastic layer forms the inside surface of said box; and where said layer deforms along abutting edges of said elements seals open seams between said elements to cause the interior of said box to be completely surrounded by electrically conductive material, wherein said box has an aperture in said sheet allowing access to said layer, and wherein said sleeve has an aperture coming into registration with said aperture in said box when said box is in said sleeve; whereby said layer may have electrical contact made there-with when said box is in said sleeve.
Claim 8
Dependent Claim
42 words
A transportation container according to claim 5 wherein said sleeve has more than one aperture; whereby said box may be inserted into said sleeve in any one of a plurality of orientations; and still provide access to the aperture in said box.
