Embodiments are directed to improving transportation of tubular structures. A roller may have a housing having a vertical axis and one or more upper flanges. The one or more upper flanges may have an upper surface that is transverse and non-perpendicular to the vertical axis of the housing. Optionally, the upper surface may be curved. The roller may have one or more wheels that are rotatably coupled to the housing and that extend downward from the housing.

A pack of cardboard with a base, a fixed lid and an encircling side wall, has a reclosable removal opening provided in the lid. The removal opening may be covered by a movably arranged cardboard layer. More than one cardboard layer may be provided for covering the removal opening.

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.

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.

A system for assembling a container and closure comprising an expanding collet which has a plurality of pivoting collet segments, each configured to simultaneously pivot radially outward about a pivot point and comprising. The collet comprises a lip that is engagable with the rim of the open end of the container and an angled tip positioned radially inward from the lip and shaped to press a countersink portion of the closure against an interior wall of the container as the collet segments pivot radially outward. As the container and the chuck are brought together, the rim engages with the lips of the collet segments and causes the angled tips of the collet segments to pivot outward toward the interior wall of the container, thereby pushing the countersink portion of the closure against the interior wall of the container.

Embodiments provide a cup with an integrated lid that comprises top, center, and bottom portions. The top portion of the cup defines an opening and is attached to a plurality of integrated lid sections extending from the top portion and separated from the top portion by one or more fold lines. The plurality of integrated lid sections may be folded inward over the opening defined by the top portion to cover and at least partially seal the opening. The center portion defines a sidewall that extends between two ends that are affixed to at least each other. The bottom portion extends from the center portion and defines a base. The plurality of integrated lid sections may interlock to define a lid. The lid may be configured with a hole or spout for drinking or pouring the contents of the cup. The base, sidewall, and lid may define a frustoconical shape.
