Moisture stabilized package

Claim 2

An improved-strength-retaining moisture-stabilized package comprising in combination a container prepared from corrugated standard paperboard having peaks and flutes said container having four side walls, a closed bottom and an open top with a polymeric covering encompassing said four walled exterior surfaces and the exterior of said bottom portion of said container, and a water vapor permeable cover for covering said top open portion of said container said cover being prepared from standard paperboard having high porosity whereby said cover permits water vapor to be displaced upwardly from the interior of said container to pass through said cover and said polymeric covering prevents air currents from passing through the interior of said container, thereby resulting in a moisture-constant state within the interior of said package.

Claim 3

A storage unit for the containment of bulk chemicals in varying humidity conditions and which comprises a pallet which comprises a top and a bottom deck prepared from at least a partially corrugated first material having peaks and flutes and which decks are substantially parallel to each other and a series of stringers which connect said decks and which are prepared from at least a partially corrugated second material, with the proviso that said stringers each lie in a separate plane which is perpendicular to the parallel planes of the top and bottom decks and are proofed against water resorption by the use of waterproof contact cement to bond said stringers and said decks; and positioned on top of said pallet at least one package comprising a multi-cell container prepared from at least a partially corrugated third material having peaks and flutes, a polymeric film encompassing the outermost peripheral side wall and bottom portion of said container and a cover being prepared from standard paperboard having high porosity whereby said cover permits water vapor to be displaced upwardly from the interior of said container to pass through said cover and said polymeric covering prevents air currents from passing through the interior of said container, whereby resulting in a moisture-constant state within the interior of said package.

Claim 4

A storage unit for the containment of bulk chemicals in varying humidity conditions and which comprises a pallet which comprises a top and a bottom deck prepared from at least a partially corrugated first material having peaks and flutes and which decks are substantially parallel to each other and a series of stringers which connect said decks and which are prepared from at least a partially corrugated second material, with the proviso that said stringers each lie in a separate plane which is perpendicular to the parallel planes of the top and bottom decks and are proofed against water resorption by the use of waterproof contact cement to bond said stringers and said decks; and positioned on top of said pallet at least one package comprising a multi-cell container prepared from at least a partially corrugated third material having peaks and flutes, a polymeric film encompassing the outermost peripheral side wall and bottom portion of said container and a cover being prepared from standard paperboard having high porosity whereby said cover permits water vapor to be displaced upwardly from the interior of said container to pass through said cover and said polymeric covering prevents air currents from passing through the interior of said container, whereby resulting in a moisture-constant state within the interior of said package.

Claim 5

A process of improving the long-term moisture resistance of a moisture permeable standard corrugated paperboard six-sided container, one side being a removable cover for said container, which comprises in combination the steps of: (a) providing a polymeric covering about the five non-cover sides of the container; and (b) placing said cover on top of said container, said cover being prepared from standard paperboard, having high porosity whereby said cover permits water vapor to be displaced upwardly from the interior of said container to pass through said cover and said polymeric covering prevents said air currents from passing through the interior of said container, thereby resulting in a moisture-constant state within the interior of said package.

Claim 6

A process of improving the long-term moisture resistance of a moisture permeable standard corrugated paperboard six-sided container, one side being a removable cover for said container, which comprises in combination the steps of: (a) providing a polymeric covering about the five non-cover sides of the container; and (b) placing said cover on top of said container, said cover being prepared from standard paperboard, having high porosity whereby said cover permits water vapor to be displaced upwardly from the interior of said container to pass through said cover and said polymeric covering prevents said air currents from passing through the interior of said container, thereby resulting in a moisture-constant state within the interior of said package.

Claim 7

A process according to claim 3 wherein said container has multiple internal cells.

Claim 8

A process according to claim 3 wherein a moisture laden bulk material is loaded into said container before said cover is placed in position and excess water vapor is immediately vented off through a vent provided in said cover.

Claim 9

A process according to claim 5 wherein said bulk material is butyl rubber and said polymeric cover is polyethylene film.

Claim 10

A process according to claim 5 wherein said vent is sealed off after venting.

Claim 11

A process according to claim 7 wherein vent is sealed off immediately after venting.

Claim 12

A process according to claim 3 wherein said polymeric cover is in the form of a shroud placed around said five sides.

Claim 13

A process according to claim 3 wherein said polymeric cover is coated on the five non-covered sides.

Claim 14

The process according to claim 3 wherein said polymeric covering is a heat shrinkable film.

Claim 15

The process according to claim 3 wherein said polymeric film is a non-heat shrinkable film.
