The present disclosure relates to a paperboard sealing disc for use in a packaging container, comprising a peripheral edge portion surrounding a tear-open part having a push-tab and a pull-away part. The tear-open part is delimited from the peripheral edge portion by a first cutting line in the first side and by a second cutting line in the second side. Said first cutting line being provided at a distance d1 from said sealing disc outer edge, and said second cutting line being provided at a distance d2 from said sealing disc outer edge. The push-tab is at least partly delimited from the pull-away part by a folding line. At the push-tab d1>d2 and at the pull-away part d4>d3. Furthermore, d1 at said push-tab is substantially the same as d4 at said pull-away part and d2 at said push-tab is substantially the same as d3 at said pull-away part.

A composite container having a paperboard hollow body with top and bottom open ends. The body is formed by a sidewall with inner and outer surfaces. The composite container includes a body liner extending peripherally about the inner surface of the body and a base connectable to the bottom open end of the hollow body. The base includes a sidewall sized and shaped to fit snugly within the bottom open end of the body. The sidewall is permanently coupled to a bottom portion of the liner. The composite container also includes a collar connectable to the top open end of the hollow body. The collar has a peripheral portion that abuts the top open end and an inner circumferential flange sized and shaped to fit snugly within the top open end of the body. The inner circumferential flange is permanently coupled to a top portion of the liner. The peripheral portion has regions of weakened strength so that the section of the peripheral portion that abuts the top open end can be removed, thereby allowing a user to rapidly remove the coupled collar, liner and base from the hollow body.

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.

A lid is capable of easily taking out contents from an opening portion thereof, while securing sealability of a container. The lid includes a top lid made of a paper-based material, the top lid including: an opening portion communicating between the inside and the outside of the top lid; a lid piece formed to be capable of opening or closing the opening portion; and a holding portion for holding the lid piece in a state where the opening portion is opened; and the lid includes a holding reception portion configured to hold the holding portion in a state where the opening portion is opened.

A lid that closes a mouth of a container is made of a material principally including a paper material. The lid includes a side wall that is fitted into the mouth of the container, and a top lid that is surrounded by the side wall. The top lid includes an inlet/outlet formation part that forms an inlet/outlet for an article stored in the container, and a temporary fixing part that temporarily fixes the inlet/outlet formation part to the top lid. This can achieve a lid that has satisfactory thermal insulation, can reduce leakage, is user-friendly, can reduce a manufacturing cost, and is conscious of environmental issues.

A cartridge for a fluid distributer, including a cartridge housing, the bottom wall being arranged at an angle to the front wall less than 90 degrees; a fluid-containing package including a bag containing a fluid product in an interior of the bag. A fluid distributor including: a distributor housing including a door covering a portion of a front side of the housing, the front wall or the door including a window; a receiving surface extending rearward and upward from the front wall, the housing forming a cartridge receiving recess, a front surface of the cartridge being visible through the window when installed therein, the front wall and the receiving surface being configured to match a form of the cartridge; an operating member operatively connected to a pressure member configured to apply pressure to the dispensing tube upon rotation of the operating member when the cartridge is installed in the distributor.

A composite container having a paperboard hollow body with top and bottom open ends. The body is formed by a sidewall with inner and outer surfaces. The composite container includes a body liner extending peripherally about the inner surface of the body and a base connectable to the bottom open end of the hollow body. The base includes a sidewall sized and shaped to fit snugly within the bottom open end of the body. The sidewall is permanently coupled to a bottom portion of the liner. The composite container also includes a collar connectable to the top open end of the hollow body. The collar has a peripheral portion that abuts the top open end and an inner circumferential flange sized and shaped to fit snugly within the top open end of the body. The inner circumferential flange is permanently coupled to a top portion of the liner. The peripheral portion has regions of weakened strength so that the section of the peripheral portion that abuts the top open end can be removed, thereby allowing a user to rapidly remove the coupled collar, liner and base from the hollow body.

A blank 10 for forming a disposable cup, the blank including a cardboard sheet designed to be formed into a body of a cup, the blank including an edge 12 in a form of a first arc for forming the bottom edge of the cup, and a folding line for forming the rim of the cup, wherein the folding line for forming the rim of the cup contains a first folding line 14 formed by a plurality of interconnected arc-shaped folding lines 16 each arcing to the opposite direction than the first arc, and wherein a foldable wing 18 extends form each arc-shaped folding line, the wings being configured to be folded towards the center of the formed cup to lock onto each other to form a cover over the opening of the cup. The present application also provides a disposable cup formed from the blank, and a method for preparing a disposable cup.
