Abstract:
A substantially paper-based composite container for an off-gassing product includes a paperboard can body having a substantially gas-impervious liner attached to an inner surface thereof, and a pair of substantially paper-based end closures attached to the opposite ends of the can body, each end closure defining a generally cylindrical sealing panel in contact with an inner surface of the can body. Heat-sealable materials are disposed on opposing surfaces of the sealing panel and can body. The sealing panels of the end closures are attached to the can body by heat seals. The heat seal for at least one of the end closures is discontinuous such that at least one vent channel extends through the heat seal so as to establish fluid communication between an interior of the composite container and the environment outside the composite container. The at least one vent channel is operable to vent excess gas pressure from the interior of the container.

Claim (Index 1):
A substantially paper-based composite container for an off-gassing product, comprising:\n a can body comprising a tubular wall constructed from paperboard wrapped about an axis, the can body having a top end and a bottom end each defining an opening, the can body further comprising a substantially gas-impervious liner attached to an inner surface of the paperboard of the can body; a pair of substantially paper-based end closures attached to the top end and bottom end of the can body, each end closure defining a disk-shaped central portion, a sealing panel portion disposed circumferentially outwardly of the central portion, and an outer peripheral portion disposed circumferentially outwardly of the sealing panel portion,\n wherein the sealing panel portion is in contact with an inner surface of the can body and the outer peripheral portion is in contact with an outer surface of the can body, \n wherein the end closures are attached to the can body by a first plurality of separate, spaced sealed regions between the sealing panel portion and the can body and a second plurality of separate, spaced sealed regions between the outer peripheral portion and the can body, and \n wherein the first plurality of sealed regions and the second plurality of sealed regions are circumferentially aligned; \n at least one first unsealed channel disposed between the sealing panel portion and the can body; and at least one second unsealed channel disposed between the outer peripheral portion and the can body, wherein the at least one first unsealed channel and the at least one second unsealed channel are circumferentially aligned, such that the aligned channels allow the venting of gas pressure from an interior of the composite container to an environment outside the composite container.
