The present invention describes tunable methods of treating cellulosic materials with a barrier coating comprising a prolamine and at least one polyol fatty acid ester that provides increased oil and/or grease resistance to such materials without sacrificing the biodegradability thereof. The methods as disclosed provide for adhering of the barrier coating on articles including articles comprising cellulosic materials and articles made by such methods. The materials thus treated display higher lipophobicity and may be used in any application where such features are desired.

A method of forming a coating on a cylindrical paperboard container having a closed end. The method includes the steps of heating a gas from a first temperature to a second temperature; providing the gas to a first inlet of a nozzle; providing a polymer in a liquid state at a third temperature; providing the polymer to a second inlet of the nozzle; and spraying the polymer onto the cylindrical paperboard container using the nozzle; wherein the second temperature is greater than the third temperature; and the second temperature and third temperature are such that the gas maintains the polymer in the liquid state at least until the polymer comes into contact with the cylindrical paperboard container. A system for applying a coating to a plurality of cylindrical paperboard containers and a container for a consumer product are also provided.

An erectable-type container having excellent durability is provided.

The container 1 includes a bottom part 11, a side part 12 forming a box-shaped storage la with the bottom part 11, and a cross section appearing on a periphery 11a of the bottom part 11 is sealed with an insoluble sealing material which prevents moisture infiltration, and the side part 12 is adhered to the bottom part 11 by adhesive or the sealing material interposed between the cross section appearing on the periphery 11a of the bottom part 11. Further, the bottom part 11 is circular; and the side part is annular. Furthermore, the side part 12 is formed by engaging a belt-shaped body having an engagement protrusion 121 on one end and an engagement recess 122 on another end.

A liquid container made entirely from natural plant materials is revealed. The liquid container includes a cap and an upper portion made from plant fiber by mold injection, a body made of a spiral paper tube having at least two-layer structure, and a base produced by molding of composite paper. The body and the base are connected by adhesives. A fastening member is disposed on an area where the upper portion and the body are connected for improving reliability and structural strength of the area while a mounting groove formed by rolling is arranged at an area where a bottom end of the body and the base are connected by adhesives. The fastening member and the mounting groove improve connection reliability and structure strength. The liquid container with excellent structural strength is more resistant to pressure in radial and longitudinal directions and used to fill pressurized beverages or liquid such as carbonated drinks.

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.

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.
