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 package is defined to retain a first product and a separate ingredient. The package includes a hollow tubular body and first and second end closures sealed to the ends of the tube. A retainer cup is provided for storing the separate ingredient. The retainer cup includes a generally tubular cup wall, with an upper edge portion defining a support rim that surrounds a cup opening. One sidewall of the cup wall includes a plurality of concave curved groves forming a scalloped surface. The scalloped surface extends longitudinally along the cup wall and defines a scalloped edge profile for the support rim. A closure lid overlies the cup opening and closes the separate ingredient within the cup interior.

A paperboard structure including a paperboard substrate having a first major side and a second major side, a barrier coating layer on the first major side of the paperboard substrate, a top coat on the first major side of the paperboard substrate, wherein the barrier coating layer is positioned between the paperboard substrate and the top coat, and a heat-sealable barrier coating layer on the second major side of the paperboard substrate.

Disclosed is a device for protecting and preserving a substance in a container. The device may include a plurality of overlapping sectors capable of rotating about a pivot point such that the device has a substantially disc shape when fully expanded and a substantially pie shape when partially expanded; and a lip defining an outer diameter of the device when fully expanded. The outer diameter of the device is equal to or greater than an inner diameter of the inner surface of the container.

A cup having an endless sidewall with a lower stacking shoulder formed of a sidewall and bottom heel including a convexly outwardly curved rib disposed at a transition between the sidewall and a cup bottom having a bottom wall having a recessed dome-shaped center section providing draw ratio bottom wall thickness reduction to an annular flat bottom wall section defining a puncture region of the cup. The cup sidewall has a ribbed section disposed adjacent the heel and extends upwardly at least one-quarter the height of the cup helping to strengthen the relatively thin sidewall to prevent it from undesirably deforming during puncturing of the cup bottom during beverage making. The cup may include an upper shoulder formed of an outwardly expanded section of the sidewall adjacent the top of the cup and defining an filter attachment seat on one side and a cup carrier on the opposite side.

A paper bottle includes a cap, a mouth, a body and a bottom. The mouth has a tube and a body top. The cap can be to seal the tube. The tube is made of biodegradable plastic. A top end of the body is closely connected with the body top. The body is consisted of two layers of paper-based composite paper. The two layers of paper-based composite paper are spirally wound to form a tubular structure. The bottom is made of wood-pulp paper and closely connected with a bottom end of the body.
