A paper or other fibrous container is capable of maintaining a consistent gas level after sealing, as well as having sufficient stiffness to carry liquids and other heavy materials as well as light weigh materials such as medication and supplements. Preferred embodiments include a fibrous outer sleeve having an inwardly directed curled edge, a first metal sleeve positioned inward of the fibrous outer sleeve, and a bottom piece having a top metal layer. The bottom piece is preferably disposed intermediate the inwardly directed curled edge and the first metal sleeve. A first adhesive is preferably disposed intermediate the bottom piece and the first metal sleeve, and a second adhesive is preferably disposed intermediate the bottom piece and the inwardly directed curled edge.

A refillable cosmetic container system comprising an outer container that can be closed by an optional lid, and an inner cosmetic holding canister that can be removably mounted within the container. A coupling system can be implemented to allow the outer container and the inner canister to be selectively coupled to each other, such as a lug-and-groove interface, latch and catch interface, etc. The coupling system may be configured such that rotation of the inner canister relative to the outer container causes the coupling/decoupling (e.g., locking/unlocking) between the outer container and the inner canister. To aid in selective coupling (e.g., coupling and decoupling) of the inner canister with respect to the outer container, a handle is provided on the inner container.

A container comprising a bottom and a sidewall extending upwards from the bottom and terminating at an upper free edge, said upper free edge of the sidewall forming an opening of the container, said sidewall and said bottom comprising an outer paperboard layer and a thin inner plastic foil layer, formed in a thermoforming operation, said upper free edge of the sidewall comprising a rim portion extending past the outer surface of the paperboard layer of the sidewall. The rim portion comprises a rolled up portion of an upper portion of the outer paperboard layer of the sidewall, said rolled up portion being covered by a portion of the thin inner plastic foil layer. In this way, a stiff upper rim is provided, while allowing the use of a very thin inner plastic foil layer.

A method for manufacturing a paperboard bottle and spiral-wound paperboard bottle. The bottle has a tubular body portion, a shoulder and neck portion having a circular cross-section narrowing from the body portion to a circular mouth. The paperboard bottle is a liquid packaging board having thermoplastic polymer coating on both sides. The method includes cutting a planar elongated blank from a packaging board sheet. Protecting exposed cut raw edge of the first longitudinal edge against absorption of liquid. Securing the first end of the blank to a rotatable mandrel having a rotation axis (x) and an outer shape corresponding to the shape of the bottle. Rotating the mandrel to wind the blank spirally onto the mandrel, so that the longitudinal edges overlap applying heat-sealing energy and pressure, onto the overlapping longitudinal edges to form a bottle with hermetically sealed spiral seam and removing the mandrel from inside the bottle.

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 container with a deep recessed bottom end construction is provided. The container includes an inner receptacle having a sidewall and a bottom wall defining an interior volume within the receptacle. The container further includes an outer sleeve wrapped around the inner receptacle with a lower end extending below the lower edge of the receptacle to form a deep bottom recess within a lower portion of the container. The lower end of the receptacle sidewall has a taper angle that is different from a taper angle of an upper portion of the sidewall. The lower end of the receptacle sidewall may engage or contact the inner surface of the outer sleeve. The outer sleeve may include reverse bend and/or a second bottom wall onto which a lower end of the receptacle may sit.
