A 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 to establish fluid communication between an interior of the container and the environment outside the container. The at least one vent channel is operable to vent excess gas pressure from the interior of the container.

A container with a deep recessed bottom end construction is provided. The container includes an inner receptacle having a sidewall and a bottom wall defining an interior volume within the receptacle. The container further includes an outer sleeve wrapped around the inner receptacle with a lower end extending below the lower edge of the receptacle to form a deep bottom recess within a lower portion of the container. The lower end of the receptacle sidewall has a taper angle that is different from a taper angle of an upper portion of the sidewall. The lower end of the receptacle sidewall may engage or contact the inner surface of the outer sleeve. The outer sleeve may include reverse bend and/or a second bottom wall onto which a lower end of the receptacle may sit.

A manufacturing apparatus for assembling a container including a sleeve, a bowl cover with a cavity, a closed state clamshell with a hinge having a mating protrusion, and a flexible strip having a primary and secondary end portions that are affixed with adhesive between the cover and clamshell. The manufacturing apparatus includes a base, a spindle, with primary and secondary radially extending platforms, respectively supporting primary and secondary cradles with the bowl and clamshell disposed therebetween the cradles that are rotated. The manufacturing apparatus also includes a guide slidably engaged to the base, wherein the guide directs the strip to be helically wound about the clamshell and cover with a base slide mounted adhesive nozzle that affixes the primary and secondary end portions of the strip to the cover and clamshell with a head that cuts and holds the strip with the head slidably engaged to the base.

A composite container having a paperboard hollow body with top and bottom open ends. The body is formed by a sidewall with inner and outer surfaces. The composite container includes a body liner extending peripherally about the inner surface of the body and a base connectable to the bottom open end of the hollow body. The base includes a sidewall sized and shaped to fit snugly within the bottom open end of the body. The sidewall is permanently coupled to a bottom portion of the liner. The composite container also includes a collar connectable to the top open end of the hollow body. The collar has a peripheral portion that abuts the top open end and an inner circumferential flange sized and shaped to fit snugly within the top open end of the body. The inner circumferential flange is permanently coupled to a top portion of the liner. The peripheral portion has regions of weakened strength so that the section of the peripheral portion that abuts the top open end can be removed, thereby allowing a user to rapidly remove the coupled collar, liner and base from the hollow body.
