Definitions
- the present invention relates to an expander device for keeping an opening in a pouch open.
- the present invention also relates to a package system, which comprises the expander device, and to a method of using said package system.
- Consumer products such as food, cosmetics, cleaning supplies or medicine, are often filled and packaged in bags or pouches large enough to provide consumers with multiple servings.
- the consumer opens the packaging along a tearing line or by cutting an opening in the packaging to access the contents of the packaging. If not all the product is used at once, the consumer is confronted with the problem of storing the remaining content for later use.
- the consumer may choose to empty the product from the packaging into a storage box.
- the consumer may decide to leave the product inside the packaging and close the opened packaging with a clip, adhesive tape or rubber band that are often supplied with the packaging.
- a known disadvantage of using a storage box is that there is a risk that substances or microorganisms left inside the storage box may contaminate or damage the product and thus, reduce product integrity and safety. This is particularly problematic for products that demand a high level of hygiene and product integrity and safety, such as food products for infants or vulnerable persons. While it is possible to circumvent the problem of initial product contamination by simply leaving the product inside the original packaging, it can be found that this solution is not only inefficient, difficult to use and unsuitable for performing accurate product dosing, but also that the initial level of hygiene inside the packaging cannot be maintained over an extended period of time. For example, depending on the size of the opening in the packaging, it can be difficult to retrieve the product inside the packaging with a dosing device, such as a scoop or cup.
- a dosing device such as a scoop or cup.
- a first aspect of the invention relates to an expander device for keeping a pouch opening of a pouch open.
- the expander device comprises a ring member, by which a central opening is at least partially surrounded.
- the ring member comprises at least one flap being convertible between an expanded position and a collapsed position.
- the flap In the expanded position, the flap extends from the ring member on one side of the central opening to keep clear of the central opening for allowing to bring the ring member into alignment with a circumferential rim section of the pouch opening.
- the flap In the collapsed position, the flap extends from the ring member at least partially into or through the central opening so that a fitment section of the flap faces laterally outside with respect to the central opening so as to be fitted against an inner side surface of the rim section to keep the pouch opening open.
- an expander device is provided that is suitable for keeping an opening (e.g. an aperture, orifice or perforation) in a pouch open.
- the expander device comprises a ring member, which defines a central opening therein.
- the ring member may comprise a (not necessarily circular) body with an opening that may be arranged centrally.
- the ring member comprises at least one flap that is convertible between two (different) positions (configurations).
- the conversion maybe reversible.
- the flap maybe a structural element that maybe attached along one of its edges to the ring member, preferably such that the flap may be relatively movable, e.g. pivotable, with respect to the ring member between at least two positions.
- the flap In the expanded position, the flap extends preferably entirely on (only) one side of the central opening.
- the expander device may be configured such that, in the expanded position, the flap does not block or overhang the central opening and/or it does not to come into contact with any part on the opposite side of the central opening.
- the flap In the collapsed position, the flap extends from the ring member at least partially into or through the opening in order to engage with or to apply contact pressure to the inner side surface of the rim section for keeping the pouch opening open.
- 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 capable of being convertible between (at least) the following two positions:
- a first position (the expanded position) exists, where the expander device can be aligned and positioned onto the pouch opening. It is advantageous that in this position the flap(s) are on a single side of the central opening as the flaps can be used for (manually) holding the expander device to arrange and align the ring member with the pouch opening. As none of the flaps overhangs or suspends into the central opening in this configuration, the risk that they get caught inside the pouch is reduced. In addition to simplifying the alignment process in this manner, hygiene can be improved as well since the hand of the operator is not at risk of coming into contact with the pouch.
- a second position (the collapsed position) exists, where the pouch opening is securely held in place with respect to the pouch opening.
- the flap(s) may somehow cooperate with the pouch opening, the ring member or other (external) components (e.g. a storage container) for applying a holding force onto the pouch material.
- the central opening defines an opening with a shape, by which access to the pouch can be improved since the shape of the central opening can be designed independently from the shape of the pouch opening. This allows to tailor the shape of the central opening to a measuring device required for the application and to use the expander device for a plurality of different products. Also, this facilitates to access the entire content of the packaging more easily. Once the packaging is fully emptied, the expander device can be reused and cleaned, thereby improving the environmental footprint of the individual packaging.
- the expander device allows to overcome the drawbacks of known packaging solutions.
- the flap may be integrally formed with the ring member.
- the flap may be a constituent part of the ring member.
- the flap may be manufactured by two-component injection molding, so that, for example, the flap may be formed as a unit with the ring member.
- This configuration allows to simplify the manufacturing and cleaning of the expander device so that the level of hygiene can be improved.
- the flap may be provided on an edge section of the ring member.
- the expander device may be configured such that in operation, it is (preferably only) arrangeable on the pouch such that the one side of the central opening is above (up from) the pouch opening, such that it faces away from the pouch opening, and/or such that it is on the same side with respect to the pouch opening as with respect to the central opening.
- the flap may be provided on an upper edge section of the ring member. Thereby, it is possible to easily manipulate the flap(s) in operation.
- the flap may comprise a fastener for applying and/or maintaining contact pressure against the rim section of the pouch opening.
- the flap may comprise a fastener for fixing the flap at least in the collapsed position.
- the fastener may be a locking structure or a magnet.
- the fastener may be fixable with a fastener counterpart that may be provided at the ring member or at a storage container for receiving the pouch.
- the flap(s) in the collapsed position, the flap(s) may extend (fully) on the side opposite to the one side with respect to the central opening.
- the flap with a structure for (at least or only) temporarily fixing or securing the flap in its position with respect to the rim section.
- a holding force is generated or increased through the provision of fasteners.
- the pouch opening can be releasably, conveniently and safely secured so that it is possible to use the entire space available in the pouch opening.
- the flap may have a length in an extension direction being equal to or larger than a height or thickness of the ring member.
- the flap may have a length in an extension direction being equal to or larger than a height of the central opening.
- This configuration facilitates that the flap has a sufficient length for ensuring contact between the inner side surface and the flap.
- the expander device and/or the ring member may comprise a plurality of flaps.
- the flaps may be (evenly) distributed about the (inner and/or outer) perimeter (circumference) of the ring member.
- the expression “circumference” and “perimeter” may be used interchangeably and generally may be understood, for example, as any (circumferential and/or continuous) external boundary of the ring member or outer edge around it.
- the outer perimeter of a square- or rectangular-shaped ring member may be defined by its four external side edges.
- the capabilities of the expander device to keep the pouch opening open can be improved as the flaps are engageable with different portions of the pouch opening.
- the expander device can be centred with respect to the pouch opening. Also, holding forces can be balanced with such configuration as well as the pouch opening can be expanded equally on each side along the circumference of the pouch opening.
- the at least one of the at least one or plurality of flaps may comprise a levelling section provided at a distal edge of the flap with respect to the ring member, wherein, in the collapsed state, the levelling section bulges towards the central opening or is laterally offset from the fitment section towards the central opening.
- a section can be provided which allows for a dosing device, like a spoon or a scoop, to easily slide along so as to easily remove excess powder, e.g., from a bowl preferably having a defined volume, thus allowing for a highly accurate dosing.
- a dosing device like a spoon or a scoop
- the levelling section is provided at the flaps, it can be integrally provided and does not require an additional element. Also, as the flaps are in the collapsed state during use, the levelling section is securely placed inside the pouch and above the product received therein, so that excess powder easily falls back into the pouch.
- the levelling section may comprise a straight edge section.
- the ring member may comprise a circumferential attachment section, which may at least partially surround the central opening.
- the circumferential attachment section may be suitable (and/or configured) to fit the expander device at the rim section of the pouch opening or at a container opening of a storage container that is suitable for receiving a or said pouch.
