A self-priming-pump-equipped packaging bottle includes a tubular bottle body containing therein an upper seal assembly, a lower seal assembly, and piston from top to bottom. The upper and lower seal assemblies and the tubular bottle body form a closed material-feeding chamber. The lower seal assembly, the piston, and the tubular bottle body form a closed material-storing chamber. The lower seal assembly primarily has a seal seat with a through hole and an elastic sealing gasket covering the through hole from above. The upper seal assembly has an umbrella-shaped member, a hollow material-feeding column, a support post, and an end sealing cap. The end sealing cap is fixed in the umbrella-shaped member through the support post. The hollow material-feeding column's bottom surface, the support post, and the end sealing cap form a material outlet. The umbrella-shaped member lower end is in interference fit with the seal seat.

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.

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 plastic capsule has an integrated dispensing device for a substrate accommodated in the plastic capsule. The capsule comprises a capsule body, an opening element and a capsule cover. The capsule body and the capsule cover define a capsule interior for the substrate, in which the opening element is arranged in such a way that the opening element can be moved toward the capsule cover. The capsule cover can be brought from a closed state into an open state by the opening element. The capsule cover has a peripheral fastening edge and a plurality of flaps, which are connected to the fastening edge by one hinge each, in particular a film hinge, the movement of the opening element toward the capsule cover causing a deflection of the flaps around the respective hinges.

A container closure includes an outer cap, an inner cap, and a seal. The outer cap includes a top wall and an outer sidewall extending downward from the top wall. The inner cap is secured within the outer cap and includes a bottom wall and an inner sidewall extending upwardly from the bottom wall. The seal is secured to the inner cap and includes a seal sidewall and a rim extending inwardly from the seal sidewall. The seal sidewall sealingly engages the inner sidewall and the rim sealingly overlaps the bottom wall. The inner cap together with the seal define an air pathway in fluid communication between a space between the outer and inner caps and an air opening formed on the bottom wall of the inner cap and selectively covered by the rim.
