The invention relates to an expander device (100) for keeping a pouch opening (410) of a pouch (400) open. The expander device (100) comprises a ring member (120), by which a central opening (110) is surrounded. The ring member (120) comprises at least one flap (150) that is convertible between an expanded position and a collapsed position. In the expanded position, the flap (150) extends from the ring member (120) on one side (111) of the central opening (110) to keep clear of the central opening (110) for allowing to bring the ring member (120) into alignment with a circumferential rim section (411) of the pouch opening (410). In the collapsed position, the flap (150) extends from the ring member (120) into or through the central opening (110) so that a fitment section (151) of the flap (150) faces laterally outside with respect to the central opening (110) to be fitted against an inner side surface (412) of the rim section (411) to keep the pouch opening (410) open. The invention further relates to a package system (200) comprising the expander device (100) and a pouch (400) carrying a food product, and to a method for use of said package system (200).

The invention relates to a package system (200), which comprises a pouch (400) for a food product and an expander device (100) for keeping a pouch opening (411) of the pouch (400) open. The expander device (100) comprises a ring member (110) with a central opening (111) that is surrounded by an outer circumferential fitment section (112), which faces away from the central opening (111). The ring member (110) is convertible between a collapsed constitution for being inserted into the pouch opening (411) and an expanded constitution for securing the pouch opening (411). Therein, an outer circumferential perimeter of the ring member (110) at the fitment section (112) is smaller in its collapsed constitution than in its expanded constitution. The expander device (100) is configured to be inserted in the collapsed constitution with the fitment section (112) into the pouch opening (411) to keep the pouch opening (411) open by fitment of the fitment section (112) against an inner side surface (413) of the pouch opening (411) when the ring member (110) is converted into the expanded constitution. The invention further relates to a method of using said package system (200).

A collection bag is for receiving a collected material and an emptying opening configured in a specific shape for the collection bag which has a receiving space defined by a woven cloth. The receiving space is defined by outer edges of the collection bag. The woven cloth is at least partially air-permeable. The receiving space has an inlet opening for a blower air flow supplying the material and a closable emptying opening for removing the material. The receiving space opens into a tubular outlet section, the open end thereof forming the emptying opening. In a closed position of the outlet section, the receiving space or the emptying opening is closed. In an open position, the receiving space is connected to the surroundings via the emptying opening. In its open position, the outlet section protrudes from the bag and, in its closed position, the outlet section is located inside the bag.

The invention relates to an expander device (100) for keeping a pouch opening (411) of a pouch (400) open. The expander device (100) comprises two elements (110, 120), of which each comprises an inner ring section (111, 121) and an outer section (112, 122). The two elements (110, 120) are rotatably connected to each other about a rotation axis (RA) in a scissor-like manner so that the inner ring sections (111, 121) together form a ring member (130) with a central opening (131), and so that, when viewed perpendicularly onto the central opening (131), the outer sections (112, 122) of the elements (110, 120) surround the inner ring sections (111, 121) of the other element (120, 110), respectively. The ring member (130) comprises an outer circumferential fitment section (132) that surrounds the central opening (131) and faces away from the central opening (131) so as to be fitted against an inner side surface (412) of the pouch opening (411). The ring member (130) is convertible between a collapsed position, in which the inner ring sections (111, 121) are angled to each other to span an angle ?=?.sub.collapsed, and an expanded position, in which the inner ring sections (111, 121) span an angle ?=?.sub.expanded with ?.sub.collapsed<?.sub.expanded. The invention further relates to a package system (200) comprising the expander device (100) and a pouch (400), and to a method for use of said package system (200).
