  • CN112900012A discloses a detergent box comprising a liquid storage box, a breathable one-way valve and a liquid extraction connector assembly, wherein the top of the liquid storage box is provided with the breathable one-way valve or a breathable film assembly.
  • US2015/0336719 A1 discloses a container and closure combination, for the containment of fluids and extraction therefrom by way of an extraction tube.
  • the container comprises a closed volume with an opening configured to close the opening of the container; the closure is provided with an aperture such that the closure, upon fitment to the container opening, cannot be removed therefrom.
  • the aperture of the closure comprises a unitary elastic unidirectional valve member that can operate in a first, closed condition, to prevent a flow of fluid from the container; and a second, operational condition, with an extraction tube sealingly engaged with respect to the valve, to permit an extraction of fluid from the container through the tube.
  • US2015/0336719 discloses a cap according to the preamble of appended claim 1.
  • the cartridge solutions proposed offer complex structure of the outlet valves and/or check valves which are costly due to presence of metallic parts and/ springs, difficult to produce and problematic to recycle due to the presence of different materials. Furthermore, the liquid at the bottom of the cartridge cannot be fully extracted resulting in an undesirable waste of the product.
  • a cap for a cartridge comprises fastening means for fastening the cap to a cartridge opening and a valve configured to control liquid flow from inside the cartridge through the cartridge opening and the cap under negative pressure.
  • the valve is a deformable ball which covers one or more flow openings in a non-deformed state (NS) and deforms to allow flow through the one or more flow openings in the deformed state (DS).
  • Such a cap provides a simple yet effective way of controlling liquid flow from a cartridge.
  • a deformable ball which covers one or more flow openings in a non-deformed state (NS) and deforms to allow flow through the one or more flow openings in the deformed state (DS) minimizes or prevents leakage out of the cartridge and then allows for an easy flow or dose out of the cartridge under negative pressure.
  • the cap comprises a cap opening that is bound by an edge of the opening.
  • the valve is placed over, within or adjacent to the cap opening such that it functionally controls flow through the cap opening.
  • the cap opening may be circular or another shape, and the edge of the opening may extend from the cap towards the inside of the container.
  • the axis passing through the center of the cap is a central axis (C)
  • the direction perpendicular to the central axis is a radial direction (R)
  • the longitudinal direction (X) is the direction along the cartridge and parallel to the central axis (C) of the cap.
  • the cap may further comprise a pressure ring for securing one or more valve parts. Outer edges of the valve may be placed over the edge of the opening and the pressure ring is then placed over the portion of the valve sitting on the edge of the opening to ensure that the valve remains securely in place despite being subject to pressure and flow.
  • the pressure ring may be, for example, a gasket, a rubber band, a silicon band or the similar.
  • the fastening means may comprise one or more of a thread, groove, shoulder or other connecting part.
  • the fastening means may be an integral part of the cartridge (e.g., by moulding, printing and/or machining), or may be made separate and connected later, for example, by adhesive, tight fit, etc.
  • the fastening means can provide a simple and easy way of connecting the cap with valve.
  • the valve is in a form of a deformable ball which covers one or more flow openings in a non-deformed state (NS) and deforms to allow flow through the one or more flow openings in the deformed state.
  • the one or more flow openings extend in the radial direction (R) from the central axis of the cap (C).
  • the ball may be placed in a ball space which comprises flow openings.
  • the ball space may be an integral part of the cap, or formed separately and connected.
  • the valve may comprise a closing ring and/or other features configured to confine the ball within a ball space.
  • the ball can comprise silicone or rubber.
  • Such materials are resilient, allowing numerous cycles of ball deformation and long life span of the valve.
  • the ball may deform through compressive forces.
  • the compressive forces may be induced by the injection pin or other part of the cleaning appliance. This can provide a simple yet effective method for preventing or allowing flow through the valve and cap.
  • a cartridge comprising a rigid outer body, a flexible inner body at least partially inside the outer body, a cartridge opening, and a cap for the cartridge comprising fastening means for fastening the cap to the cartridge opening; and a valve configured to control liquid flow from inside the cartridge through the cartridge opening and the cap under negative pressure, wherein the valve consists of one of the following: i) a silicon cross piece, ii) a duckbill valve, iii) a deformable ball which covers one or more flow openings in a non-deformed state (NS) and deforms to allow flow through the one or more flow openings in the deformed state (DS).
  • Such a container or cartridge with a rigid outer body and flexible inner body provides a simple and effective way to store liquid contents inside a cartridge without leaking and ensure that most or all of the contents are able to be dispensed from the cartridge through use.
  • Using a rigid outer body allows for easy handling, storage and connection to cleaning appliances, while the flexible inner body provides for no leakage while allowing controlled flow out of the container.
  • the valve of the cap may extend at least partially over the cartridge opening to control liquid flow from the flexible inner body through the cartridge opening and the cap.
  • the valve may consist of a silicon cross piece extending over a cap opening which aligns with the cartridge opening when the cap is connected to a cartridge.
  • the silicon cross piece comprises a valve body and two slits, crossing each other perpendicularly such that at least four flaps are formed. The flaps abut each other and form a seal when the cartridge is not used. Under the negative pressure, the flaps can open to allow liquid flow through the valve.
  • This simple valve structure offers good flow control from the cartridge to the cleaning appliance using minimal parts. Furthermore, due to its simple design the valve can be easily (dis)connected to the cap and/or replaced together with the cap. It is also easy and inexpensive to manufacture such a valve, and can easily be replaced when needed.
  • the valve consists of a duckbill valve.
  • the duckbill valve comprises first and second flaps which extend from an outer edge of the cap opening towards the central axis (C) of the cap opening.
  • the first and second flaps can meet at the central axis of the cap opening to form a seal.
  • the duckbill valve offers good sealing properties using a minimal number of parts. No metallic parts and/or springs are used resulting in an economical valve solution which is easy to recycle.
  • the first and second flaps are configured to open upon receiving compressive forces to form a liquid conduit from the cartridge through the cap.
  • the compressive forces may be induced by the injection pin or other part of the cleaning appliance.
  • the injection pin may be part of the negative pressure device.
  • the injection pin may have hollow body to allow flow of the liquid from the cartridge to the cleaning appliance.
  • the duckbill valve comprises silicone or rubber. Such materials offer good flexibility needed for opening of the valve while providing sufficient strength needed to seal the valve and prevent leakage.
  • valve may be in a form of a deformable ball which covers one or more flow openings in a non-deformed state (NS) and deforms to allow flow through the one or more flow openings in the deformed state.
  • the one or more flow openings extend in the radial direction (R) from the central axis of the cap (C).
  • the ball may be placed in a ball space which comprises flow openings.
  • the ball space may be an integral part of the cap, or formed separately and connected.
  • the valve may comprise a closing ring and/or other features configured to confine the ball within a ball space.
  • the ball can comprise silicone or rubber.
  • Such materials are resilient, allowing numerous cycles of ball deformation and long life span of the valve.
  • the ball may deform through compressive forces.
  • the compressive forces may be induced by the injection pin or other part of the cleaning appliance. This can provide a simple yet effective method for preventing or allowing flow through the valve and cap.
  • the inner body can be additionally fixed to the outer body by one or more linear connections connecting an outside surface of the inner body to an inside surface of the outer body. These can be in the longitudinal direction and/or around the sides (e.g., radially).
  • the linear connections can be in a form of one long connection extending along the length of the outer body or series of short/point connections along the body, for example, on each side face. This can be achieved by an adhesive, welding, stitching, mechanical means, or the similar.
  • connection between the cartridge and a cleaning appliance can be formed by coupling a connecting insert on the cap to a negative pressure device, which could be part of the cleaning appliance or separate.
  • the connection can be air-tight to allow correct discharge of the cleaning product.
  • This connection can be through threads, a tight fit or any other means which could secure the two parts together.
  • the cap can further comprise a cap opening which allows liquid to flow through the cap. In this manner a liquid conduit is formed between the cartridge and the cleaning appliance. Under the negative pressure, for example generated by the negative pressure device of the cleaning appliance, the cleaning product can be discharged from the cleaning product space within the inner body, through the cap opening and the negative pressure device into the cleaning appliance.
  • the cartridge inner body Before use, the cartridge inner body is stretched to maximize volume of the cleaning product space, and the inner body almost completely coincides with the outer body of the cartridge.
  • the cleaning product is periodically discharged from the cartridge.
  • the volume of the cleaning product space decreases and the inner body separates from the outer body except around the one or more linear connections.
  • a volume of an unused space inside the (rigid) outer body and outside the flexible inner body increases.
  • the unused space fills with air as the cleaning product is discharged and the inner body, and as such the inner body decreases in volume.
  • the volume of the cleaning product space and the volume of the unused space together always add to a volume of the outer body.
  • a valve is placed on or in the cap.
  • the valve has the form of a deformable ball.
  • the valve is placed over the cap opening.
  • the cap has a deformable ball placed in the center of the cap and one or more flow openings that extend radially around a ball space.
  • the ball may sit within the ball space and a closing ring may be placed around the cap opening such that the ball stays within the ball space and cannot escape.
  • the flow openings allow passage of the cleaning product from the cleaning product space into the ball space and out of cartridge.
  • the ball in its natural state
  • the cartridge When in use, the cartridge may be connected to the negative pressure device via the cap.
  • the injection pin may be arranged to apply a force and deform the ball.
  • the ball is configured to be deformed such that it moves away from the closing ring, and allows for flow through the flow openings. Consequently, the liquid conduit is formed from the cleaning product space, through the flow openings and the ball space, to the cleaning appliance.
  • the ball valve provides a simple but effective way to prevent flow and leakage in a cartridge until it is ready for use.
  • the use of a compressible ball allows for sealing in a non-use state and a simple compression of that ball (e.g., by a pin) allows for flow out of cartridge.
  • This simple but effective valve is formed with minimal parts and is therefore robust and easy to manufacture and use.
  • valves As discussed in the background, past cartridges required complicated outlet valves to ensure that liquid could exit the outlet when needed, but not leak out when not in use. Such valves typically included a number of metal parts, springs, etc. Instead, the valves described in this application provide very simple, yet effective designs for ensuring that the contents of a cartridge does not leak, but is able to exit the container when connected to the proper device. None require metallic parts or springs, which typically means less degradation and therefore a longer useable life for the valve and cartridge. Additionally, this can result in an easier and less costly manufacturing process for the valves.
