Definitions

  • US 2018/186540 A1 discloses a packaging including a container, and a closure system made up of a frame and a lid hinged to the frame and able to close the container opening in a fitted manner.
  • WO 2012/085117 A1 discloses a container and a pouch, wherein the container comprises a closure for closing the container and preferably being adapted to maintain the pouch in an open state in a position where its opening is facing upwardly.
  • US 2,693,212 A discloses a closure for receptacles, wherein the closure consists of two superimposed strip-shaped braces.
  • the ring member is preferably reversibly convertible between two positions, namely, a collapsed position and an expanded position.
  • the collapsed position may be configured for inserting the expander device at least with the outer circumferential fitment section into the pouch via the pouch opening.
  • the expanded position may be configured to provide the central opening as an access opening to the pouch when the outer circumferential fitment section is (circumferentially) fitted against the rim section to keep the pouch opening (by compressive force) open.
  • the inner ring sections are angled to each other to span an angle ⁇ .
  • the angle ⁇ is the angle spanned between the inner ring sections when viewed along the rotational axis.
  • the angle ⁇ in the collapsed position is smaller than the angle ⁇ in the expanded position so that ⁇ collapsed ⁇ expanded applies.
  • a device by which the pouch opening can be expanded so that, for example, the pouch opening (or pouch material defining the pouch opening) is straightened out, spread out, unfolded, and/or increased in its extension (e.g. diameter, width).
  • the expander device can be expanded so that, for example, the pouch opening (or pouch material defining the pouch opening) is straightened out, spread out, unfolded, and/or increased in its extension (e.g. diameter, width).
  • the expander device allows to overcome the drawbacks of known packaging solutions.
  • the expander device may be configured such that in operation, it is (preferably only) arrangeable on the pouch such that one side of the central opening faces upwards (i.e. away from the pouch opening), and/or such that it is on the same side with respect to the pouch opening as it is with respect to the central opening.
  • the expander device can be placed deeper inside the pouch opening without colliding with the pouch material.
  • the expander device can be secured more safely inside the pouch.
  • structures connecting the inner ring section with the corresponding outer section may extend transversely from the inner circumferential fitment section and thereby, block relative movement of the expander device to the pouch along a direction normal to the pouch opening. By placing these structures further outside the pouch opening, the insertion depth can be increased.
  • the ring member in the expanded position, may extend substantially within a plane.
  • ⁇ expanded in the expanded position, may be 180°.
  • the outer sections may form together an outer ring member that at least partially surrounds the ring member and its central opening when viewed perpendicularly onto the central opening and/or the rotational axis.
  • the outer sections may form together an outer ring member that at least partially surrounds the ring member and its central opening in the expanded position.
  • a gap for receiving the rim section preferably in a squeezed or clamping manner may be formed between the ring member or its fitment section on the one hand and the outer sections on the other hand.

  • the expander device can also be achieved with the package system. Furthermore, it is possible to provide a package system with an expander device that is easy to clean and reusable so that packaging material can be reduced. In particular, the provision of separate elements for retrieving product from the pouch, such as a spout, can be avoided. Therein, it can be achieved that instead of having to provide each pouch with a separate opening means, the expander device only needs to be provided once for the consumer and can be reused subsequently.
