A closure for a container is described where the container has an open end and a closed end, the closure being configured to engage the open end of the container, wherein the closure comprises: a collar configured to engage the container; a lid connected to the collar by at least one hinge; wherein to facilitate engagement the collar is configured to extend over and surround the open end of the container such that an inner surface impinges on, or is immediately adjacent to, an outer surface of the open end of the container; characterised in that a plurality of beads extend outwardly from the inner surface of the collar to fixedly hold the collar in engagement with the container, wherein said beads are located substantially uniformly relative to each other and occupy less than 50% of the inner surface of the collar. A container is also described in which is provided with a docking on an inner wall of the collar suitable for releasably suspending a scoop.

A waterproof prestressing structure of water bottles or cups, which mainly has a first main body and a second main body, and one surface of an elastic body is integrally provided on the first main body. When the first main body and the second main body are screwed to connect with each other, since the one surface of the elastic body is fixed on the first main body, the one surface of the elastic body connected to the first main body does not deform, and only another surface that contacts the second main body deforms, so that the elastic body does not excessively deform in a tight state, thereby reducing twist or damage of the elastic body caused by screwing. The elastic body is integrally provided on the first main body, so that there is no gap between the elastic body and the first main body.

The present invention is directed to the system, apparatus and method for removable lids to enable users to install a lid to a container, and especially manufactured fiber (MF) containers and create a tamper resistant seal. In one embodiment of the present invention, the detachable lid includes a mounting member and a cover. A locking mechanism may be employed to secure the cover and mounting member to one another in a tamper resistant manner. The removable nature of the lid allows different types of material to be used when the lid and the container are manufactured together. For example, the lid may be made of a rigid material, while the container may be made from less expensive and more environmentally safe containers made from molded fiber and similar lightweight but less rigid biodegradable materials.

The present invention is a cup can. The cup can includes a can body and a resealable top. The resealable top includes a can lid and a cap. The can lid is attached to the can body with an interior cavity. The can lid provides an opening into the interior cavity of the can body and allows for the contents within the interior cavity to be removed. The cap is removably attached to the can lid. The cap is secured to the can lid and seals the contents of the interior cavity of the can body. The cap may be removed and reattached to the can lid, thereby providing a resealable container.

A dispensing system for use with a portable container for the storage, transport, and dispensation of fluids, especially liquids. The dispensing system includes an annular collar affixable to such a portable container. The collar is matable with a twist-top having a straw thereon. Once mated, corresponding structures on the collar and twist-stop prevent or inhibit separation. The twist-top can be twisted open to a position in which corresponding interior structures of the twist-top and collar form a fluid channel allowing liquid in the container to flow past sealing elements such as a gasket, and to egress to a contoured surface for sipping hot liquids by a human. The twist-top can be twisted close to reseal and inhibit fluid egress. Alternatively, a rotatable flip straw in the twist-top can be opened to drink cold liquids from the container while the twist-top is sealed in closed position.

A method of producing and filling a paperboard packaging container with pulverulent bulk solids includes forming a tubular container body from a paperboard sheet, the body having upper and lower body openings and a container wall extending between the upper and lower body openings and having inner and outer surfaces; closing the upper body opening with a sealing membrane attached to the inner surface; providing an upper reinforcing rim; inserting at least a lower part of the upper reinforcing rim into the tubular container body at the upper body opening; forming a weld seal between the inner surface and the inserted part of the upper reinforcing rim; presenting the body to a filling station with the bottom body opening of the container body directed upward in a vertical direction; filling pulverulent material into the body through the upwardly directed bottom body opening; and closing the bottom body opening.

A tamper evident metal foil closure for a container which provides visual evidence of tampering in the form of damage to the metal foil (e.g. tearing) and evidence of temperature tampering of the metal foil when heat is used to remove and reseal the metal foil. Containers sealed with this novel metal foil closure make it more difficult to tamper with or remove the container contents and then return the container for a refund.

A sterile container includes a container pan, a container cover, a closure for closing the sterile container, and a seal or sealing element between the container pan and the container cover. The seal or sealing element is vapor-permeable.

A paperboard packaging container for bulk solids includes a container body having a container wall extending from a container bottom edge to a container body opening and having an inner surface facing an inner compartment in the packaging container, and a lid for closing the container body opening. An upper reinforcing rim is applied at the container body opening and extends along the opening edge, defining a perimeter of a container access opening and is joined to the inner surface of the container wall by means of a weld seal which extends around the container body opening and has an upper edge including a first abutment surface arranged to abut against a second abutment surface on an inner lid surface with the lid in a closed position on the container access opening and form a tight seal between the rim and the lid with the lid in the closed position.

A paperboard packaging container for bulk solids includes a container body formed by a container wall having wall portions, and a container bottom. The wall portions are connected by corner portions and each wall portion extends in a height direction from a lower end edge at the container bottom to an upper end edge at a container opening, the height direction being perpendicular to a cross direction of the container. An upper reinforcing rim is applied to the container opening. Each of the upper and lower end edge of the container wall has end edge portions corresponding to the wall portions. At least one edge portion has an outwardly curved shape and a radius of curvature larger than a radius of curvature of each corner edge portion, the at least one end edge portion bulges outwardly with a radius of curvature of 200-700 mm, preferably 300-600 mm, more preferably 400-500 mm.
