Various enhancements of tabbed seals are provided herein with enhanced grasping functionality. Such enhancements include an anti-slip coating, a polymer adhesive layer, embossing, increasing the thickness of the tab, and/or increasing the overall surface area of the tab.

A membrane for use with a container is provided herein. The membrane comprises a first layer comprising a peripheral area defined by a first perimeter of the first layer, and a first line of weakness formed inward of the first perimeter. The first line of weakness defines a flap. The membrane further comprises a second layer comprising a peripheral zone defined by a second perimeter of the second layer and a second line of weakness formed inward of the second perimeter. The second line of weakness defines a central portion. The membrane further comprises a first seal area comprising at least a portion of the peripheral zone of the second layer being adhered to at least a portion of the peripheral area of the first seal area.

Containers for storing food in a storage compartment may include a base portion of the container. The storage compartment is sealed with a film to get the food stored in the storage compartment fresh. The container further includes a reversible lid that is able to attach to the base portion of the container in two different configurations. In a first configuration the reversible lid attaches to the base portion without affecting the seal created by the film. In a second configuration the reversible lid attaches to the base portion when the lid is inverted and the film is removed from the base portion.

The Rotatable Beverage Can Cover (200) enables a beverage drinker of a stay-on-tab beverage can (100) to drink the beverage (600) without being subjected to unsanitary lid surface conditions. The Rotatable Beverage Can Cover (200) comprises a circular surface (210), a curved side wall (300) and a notch (500). The Rotatable Beverage Can Cover (200) is fastened to the stay-on-tab beverage can (100) and placed in its “sanitary protection” position so that: a) the Rotatable Beverage Can Cover (200) covers the drinking contact area (190) and b) the notch (500) on the Rotatable Beverage Can Cover (200) allows access to the pull tab area (195). The beverage drinker rotates the Rotatable Beverage Can Cover (200) to move the Rotatable Beverage Can Cover (200) from its “sanitary protection” position to its“drinking access” position so that: a) the circular surface (210) of the Rotatable Beverage Can Cover (200) covers the pull tab area (195): and b) the notch (500) allows access to the drinking contact area (190) and the scored opening (126).

A paperboard packaging container includes a sealing arrangement comprising a lid and a sealing rim. The packaging container further includes a circumferential lid sealing member applied in the lid. The sealing rim forms a closed loop extending around the container opening. The sealing rim further comprises a first sealing surface arranged at an upper end edge of the sealing rim and is arranged to seal against a second sealing surface constituted by the circumferential lid sealing member when the lid is in a closed position. The sealing arrangement furthermore includes a frame structure forming a closed loop extending around a periphery of the container opening and is connected to the sealing rim. The lid is connected to the frame structure by a hinge member and a locking arrangement.

In an embodiment, the invention comprises a container comprising: a base; at least one sidewall extending upwardly from the base and terminating in a top edge, wherein the at least one sidewall is paper-based; a removable flexible membrane adhered to the top edge, wherein the membrane comprises a one-way valve; a liner ply at least partially adhered to an interior surface of the sidewall, wherein the liner ply is configured to at least partially release from the sidewall upon a pressure differential between the pressure within the container and the external pressure.

Various forms of tabbed sealing members are described along with the laminates from which the sealing members are formed. In some forms, the tabbed sealing members may generally be formed from materials that may be processed using a single recycling stream. In one form, the tabbed seals do not include any metal foils, such as would traditionally be included in induction heated seals. Instead, the seals may be applied in other manners, such as using ultrasonic sealing, conduction heating, high frequency sealing/welding, pressure sensitive adhesives, and the like.

A closure capsule for closing a container, comprising: a cap (2) to be associated with the container and comprising a frangible mouth (20); a cutter (3) for opening said frangible mouth (20); a covering (4) protecting said cap (2) and said cutter (3) and comprising an intactness band (40); first toothed connection means (5) afforded on the covering (4) and on the cutter (3) and that make said cutter (3) and said covering (4) rotate integrally. The closure capsule is movable from a initial configuration to an operative configuration, wherein the intactness band is removed and the frangible mouth is broken. In the initial configuration, the cap, the cutter and the covering contribute to the definition of walls of a reservoir (8) for containing a product to be dropped into the container in the operative configuration.
