A container can comprise a sidewall extending at least partially around an interior of the container, and the sidewall can have at least a first end margin and a second end margin. The sidewall can comprise at least a sidewall substrate layer, a sidewall base coat extending along the interior of the container, and a secondary layer extending in register along at least the first end margin of the sidewall. The container further can comprise a sidewall seam comprising the first end margin and the second end margin in an at least partially overlapping relationship. The secondary layer and the sidewall base coat extending along the first end margin can cooperate to form a heat seal along the sidewall seam.

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.

The present paper cup comprises a cup body, and the cup body comprises inner paper and outer paper. There are hollow bulges on the outer paper, and the outer paper forms a connecting part. The inner side of the connecting part bonds to the outer side of the inner paper, and the cup rim of the outer paper extends to the cup rim of the inner paper. In addition, the outer side of the cup rim of the inner paper bonds to the inner side of the outer paper, and both cup rims of the outer paper and the inner paper bend outward to form a double layered crimping. The manufacturing process for the present paper cup includes: paper preparation, rolling, composition, sheet cutting, forming, molding and etc.

The present invention relates to a disposable folding paper cup that folds flat and, when unfolded by the pressing of a folded portion, has a cylindrical upper end, the paper cup comprising: a cup body, which is made of a coated paper of which the inner surface is coated with a cup body coating layer, forms a cylindrical shape when unfolded, and forms a flat surface when both sides thereof are folded at folding lines; bending lines forming oval press parts that unfold bisymmetrically around each folding line when the folding line height center portion of the cup body is pressed, and dividing the oval press parts, spaced from the upper and lower ends of the cup body, therefrom; a bottom sheet which is a coated paper having a bottom sheet coating layer formed on the surface thereof so as to be fused with the cup body coating layer at the inner side of the lower end of the cup body, of which both ends are primarily fused therewith while the bottom sheet is folded along a transverse center folding line that is upwardly convex, and which is fused with the bottom edge of the folded cup body to form a bottom fused band; and fusion columns at which the front and rear surfaces, having the folding line at the center thereof, and the bottom sheet, having the end portion fitted therebetween, form a column shape higher than the fusion height of the bottom fused band and lower than the lower end of the bending line, thereby fusing, at a portion at which the bottom fused band and the folding line meet, the end portion of the bottom sheet through the three sides altogether.

The object of the invention is to produce an attractive environmentally friendly biodegradable pouring container. The body of the improved container is optimally formed in the shape of a conical frustum or cylinder. The assembly being a healthier and environmentally superior alternative to traditional plastic non-biodegradable containers. The seams and folds of the container are joined with adhesives or other means, which strengthen the vessel and prevent leakage. The adhesives may be beverage or food friendly and approved by the Food and Drug Administration as required by the container's contents. When used as a drinking-vessel the invention lends itself to a variety of choices for the lid/top designs and the methods of production are straightforward and affordable.

The tapering shape, large at the bottom and narrow on top, provides improved stability due to its lower center of gravity relative to the amount of contents in the container at any given time. Unlike traditional cylindrical beverage vessels and cups, which are narrow at the bottom and wide on top, this shape decreases the likelihood of the container being easily knocked over thereby allowing the invented container to be set on a surface with a greater angularity than containers currently in the art. As an option either container shape can be constructed with three or more protrusions or points of support around the perimeter of the base allowing for additional support or balance. This is potentially an important improvement in stability by now allowing the user to place the container on an uneven surface such as a rock, log, dashboard, console, and etcetera. Additionally, a thin coat of wax, rubber, etc. may be applied to either the base perimeter or base protrusions to add additional gripping strength to prevent the container from slipping.

The entire container may be designed to be environmentally superior by the use of biodegradable materials for all components of the assembly thereby reducing the estimated time required to biodegrade from 700 years or more for typical plastic bottles, down to a few months for the current invention
