The present disclosure provides a paperboard packaging container comprising a tubular paperboard container body, a container bottom and a container lid. The container body comprises a container body abutment edge at the container opening. The container body has an inner surface facing towards an inner compartment in the packaging container and an outer surface facing away from the inner compartment. The container lid comprises a lid collar having an abutment edge adapted for abutting against the container body abutment edge, and a lid plug-in portion. The plug-in portion has a side surface extending in the longitudinal direction and faces the inner surface of the container body, when the container lid is in a closed position. The lid collar is made of the same material as the container body and the lid collar is delimited from the container body by a slit or by weakening means.

The present disclosure provides a method of forming a paperboard packaging container comprising a tubular paperboard container body, a container bottom and a container lid. The container body comprises a container body abutment edge at the container opening. The container body has an inner surface facing towards an inner compartment in the packaging container and an outer surface facing away from the inner compartment. The container lid comprises a lid collar having an abutment edge adapted for abutting against the container body abutment edge, and a lid plug-in portion. The plug-in portion has a side surface extending in the longitudinal direction and faces the inner surface of the container body, when the container lid is in a closed position. The lid collar is made of the same material as the container body and the lid collar is delimited from the container body by a slit or by weaking means.

A container includes a body extending at least partially around an interior and including a lower marginal portion, a central portion, and an upper marginal portion at least partially separably connected to the central portion at a line of weakening, the upper marginal portion curled toward the interior of the container and defining a free edge, a closed bottom engaged with the body, a barrier member positioned in the interior of the container, and a lid member positioned in the interior of the container proximate the free edge of the upper marginal portion of the body and having a central portion, a peripheral marginal portion at least partially attached to the upper marginal portion of the body, and a pull tab extending away from the peripheral marginal portion for facilitating at least partial separation of the upper marginal portion of the body from the central portion of the body.

The present disclosure is directed to a cup including a base, a sidewall having a lower end portion connected to the base so that the base and the sidewall together define a space, and at least four flaps that are connected to an upper end portion of the sidewall via respective folding lines. The flaps are foldable relative to the sidewall between an open position, in which the flaps are oriented in parallel to the sidewall, and a closed position, in which the flaps are folded inwards so to form a lid of the cup. The at least four flaps include a first and a second flap having a first width, and a third and a fourth flap having a second width, wherein in the closed position, the at least four flaps define at least two faces of the lid, and wherein the third flap includes a drinking opening.

An environmentally friendly fresh-keeping can and a method of manufacturing the same are provided. The environmentally friendly fresh-keeping can includes a housing, an inner container, an easy-open lid, and a bottom cover. The housing, the inner container, the easy-open lid, and the bottom cover are respectively made of a spiral paper tube, bio-based polyethylene 2,5-furanoate (PEF), aluminum, and biodegradable plastic. The inner container is mounted into the housing through an inner opening on a top of the inner container. Then the easy-open lid and the bottom cover are respectively used to seal the inner opening of the inner container and a bottom opening of the housing. The respective components are made of biodegradable, recyclable and reusable materials and able to be disassembled for recycling and reuse. Thereby the can meets requirements for environmental protection and recycling.
