Definitions

  • the various aspects and examples thereof relate to the field of providing a liquid for consumption with an additive.
  • the various aspects and examples thereof relate to the field of drinking containers comprising an arrangement for filtering a liquid.
  • Adding additives to a liquid for consumption, like water, is generally executed by adding one or more substances directly in the liquid in a bottle with the additive being provided in a tablet shape.
  • a first aspect provides a regulator for providing at least one additive to a beverage.
  • the regulator comprises a regulator inlet for receiving the beverage, a regulator outlet for providing the beverage with the additive and an additive chamber having a chamber inlet and a chamber outlet, the additive chamber being arranged to receive the additive.
  • a first flow path is provided through the regulator, from the regulator inlet to the regulator outlet, which flow path is arranged to enable a flow of a liquid and the flow path ranging from the regulator inlet to the chamber inlet and from the chamber outlet to the regulator outlet, through the additive chamber.
  • additive By enabling a flow of the beverage along the additive that may be provided in the additive chamber, additive may be added to the beverage.
  • the adding may take place by means of a solid piece or granules of additive being soluble in the beverage or granules packed in a container comprising a porous material of an additive being extractable in the beverage, by small particles of the additive being taken along in the beverage - forming a suspension -, other, or a combination of two or more thereof.
  • the additive may comprise liquid components.
  • the additive chamber may be provided as a chamber separately from the regulator or it may be formed by the regulator itself, in which case inlets and outlets of both are the same parts.
  • An implementation of the regulator further comprises a second flow path, from the regulator inlet to the regulator outlet, not passing through the additive chamber.
  • this implementation allows only a small portion of additive to be taken up by a small portion of beverage, which small portion of beverage is subsequently mixed with an amount of beverage without the additive. This allows for dilution of the additive, preferably until a desired amount of additive in the total flow of beverage is provided.
  • a ratio of a first flow through capacity of the first flow path and a second flow through capacity of the second flow path is adjustable. This allows for adjustment of a total amount of additive in the beverage provided by the regulator outlet. This may be required or desired, based on taste of a user, based on a speed at which the additive is taken up by the beverage, other parameters, or a combination of two or more thereof.
  • the additive chamber comprises at least one chamber hole as a part of the first flow path, wherein an open area of the hole is adjustable. This allows for an efficient implementation of this concept.
  • Another implementation further comprises at least one blocking element arranged to block at least part the chamber hole. This provides a convenient to implement implementation.
  • the additive chamber comprises a first shell part and a second shell part and the first shell part comprises the chamber hole, the second element comprises the blocking element.
  • the first shell element and the second shell element are movable relative to one another such that movement of the first shell element and the second shell element relative to one another result in the blocking element blocking more or less of the opening of the chamber hole.
  • a further implementation comprises multiple chamber holes divides of a first group of at least one chamber hole and a second group of at least one chamber hole, wherein the chamber hole of the first group has a first size and the chamber hole of the second group has a second size, the first size being different from the second size.
  • the chamber inlet is provided by the holes. This is a relatively simple and cost effective implementation.
  • the chamber inlet is provided at a side of the chamber. This may allow for providing holes around the chamber, for example at equiangular positions, which may allow for an improved and more uniform of beverage around the additive in the chamber.
  • the chamber inlet is arranged to have a tube connected thereto. This may allow for attachments of elements such as an filter element, a conduit or any other element.
  • the tube can be configured to serve as an attachment component for a filter element at its distal end.
  • the filter element may allow removal of impurities from a fluid by trapping unwanted particles and contaminants as the fluid passes through it. This may improve the quality and safety of the fluid.
  • the filter element may be further portable.
  • the tube is configured as transport element for the beverage. This allows for an efficient implementation of this concept.
  • the chamber inlet comprises a valve at the proximal end of the chamber. This may allow regulation of the fluid passing through it.
  • valve is a one way valve, arranged to prevent backflow of at least one of the beverage and the additive back into the chamber inlet.
  • the outlet is provided at the top of the chamber. This may allow for improved mixing and uniformity of the beverage and the additive.
  • the regulator comprises a regulator chamber, the additive chamber is provided inside regulator chamber; and the second flow path is provided between the additive chamber and an inner wall of the regulator chamber.
  • a duct for the second flow path may be provided by an inner wall of the regulator chamber and an outer wall of the additive chamber. If accordingly implemented, no separate dedicated duct may be required for the second flow.
  • a further implementation further comprises a flexible spout that may function as part of the regulator outlet or an attachment part for a conduit.
  • a flexible spout and in particular a spout comprising or even consisting of a resilient material like an elastomer, is convenient for drinking a beverage or may allow attachment of a conduit. Furthermore, such spout may be conveniently closed by means of pinching.
  • the flexible spout comprises a flexible conduit as part of the regulator.
  • the flexible conduit and in particular a conduit comprising or even consisting of resilient material like an elastomer, is convenient for drinking a beverage. Furthermore, such a conduit may be conveniently closed by means of pinching, for example by bending the conduit.
  • the additive chamber is arranged to receive an additive of a first type. This allows the additive of the first type to be taken up by the first flow in the first flow path.
  • the additive chamber is arranged to receive the additive of the first type in a granular or solid form, or granules packed in a container comprising a porous material. This option is convenient to use.
  • the additive chamber is arranged to receive an additive of a second type. This allows two different additives to be used in combination, thus extending options for variation in use of multiple additives.
  • the additive chamber is arranged to receive the additive of the second type stacked on the additive of the first type. This allows for efficient use of space in the additive chamber.
  • the additive chamber comprises a porous bottom at a distal end. This may allow flow of beverage to the additives, to solve or extract the additives. This is a relatively simple and cost effective implementation
  • a drinking container with an arrangement for filtering that is more convenient to use.
  • the filter is preferably replaceable and the container may firstly be provided without the filter.
  • the container can be nearly fully filled, either with the membrane already in or with the membrane placed in the container at a later moment.
  • the second volume will be small or decrease, as the membrane is flexible.
  • a particular force is provided within at least one of the first volume and the second volume, to create a pressure difference between the first volume and the second volume such that the pressure in the second volume is lower, liquid will flow from the first volume to the second volume and will thus be filtered while passing through the filter.
  • the first volume will decrease in size and the second volume will increase in size - while the total volume of the container as defined by the outer circumferential wall will remain the same.
  • the proximal end of the membrane coincides with the proximal end of the outer wall. It is noted that such situation is desirable in use; for filling the container, any liquid to be filtered is to be provided in the second volume. And therefore, during filling, the membrane is either to be removed from the container or to be otherwise removed from the proximal end of the outer wall to provide access to the first volume. With the membrane and the proximal end of the outer wall coinciding, unfiltered liquid can only exit the first volume via the filter passage. This largely reduces or may even prevent contamination of filtered liquid with unfiltered liquid. In a further implementation, the distal end of the membrane coincides with the distal end of the outer wall. This may further reduce contamination.
  • Another implementation further comprises a skeleton structure within the membrane, the skeleton structure comprising at least one protrusion protruding from a centre of the second volume towards the membrane.
  • skeleton structure may provide shape to the membrane, in at least one of axial and radial direction. If in radial direction, the membrane may be set to extend from the proximal end of the container towards a distal end of the container, within circumferential outer wall.
  • the skeleton structure comprises at least three protrusions protruding from the centre of the second volume towards the membrane, the protrusions being substantially equiangular distributed over an axis of the second volume.
  • a volume may be defined. Implementations may be envisaged in which two protrusion provided at an angle of more - or less - than 180° define a volume having a triangular cross-section, which is equivalent.
  • the protrusions range along at least 50% of the length of the membrane. This allows for a large and long definition of the second volume, providing sufficient space for filtered liquid.
  • the membrane is a resilient membrane.
  • An advantage thereof is that the membrane may move back to an initial position. For example, if the membrane defining a second volume larger than zero is inserted in a container filled with unfiltered liquid, the liquid will exert pressure on the membrane and the second volume will become smaller. By virtue of the resilient nature of the membrane, the membrane will go back to an initial shape, thus increasing the second volume. By virtue of the increasing, firstly pressure will drop and liquid will flow from the first volume to the second volume, via the filter.
  • the cap comprises an outlet for the second volume. This allows for convenient removal of filtered liquid from the second volume and filling of the first volume.
  • the membrane is connected to the cap. This allows for convenient removal and insertion of the membrane.
  • the skeleton is connected to the cap. This allows for convenient removal from and insertion of the membrane and skeleton structure in the container provided by the outer circumferential wall.
  • a further implementation further comprises a substantially rigid inner circumferential wall between the outer circumferential wall and the membrane, the inner wall having a proximal end and a distal end and the inner wall dividing the first volume in a first sub-volume between the outer wall and the inner wall and a second sub-volume between the inner wall and the membrane.
  • This implementation provided a cartridge within the membrane provided therein and allows for quick insertion of the membrane in the container, with liquid provided in the container.
  • the inner wall comprises at least one passage for the liquid, allowing liquid to flow between the first subvolume and the second sub-volume.
  • the inner wall is connected to the cap at the proximal end of the inner wall. This provides an option for quick and convenient insertion of the cartridge with the inner wall and the membrane.
  • the outer wall is provided with a bottom wall at the distal end of the circumferential wall. This forms a container.
  • the proximal end of the circumferential wall is open and the edge of the opening is provided with a sealing liner. This allows for proper sealing between the first volume and the second volume.
  • an inner wall diameter of the outside of the inner wall at the proximal end of the inner wall is substantially the same as an opening diameter of the opening of the outer wall at the proximal end of the outer wall, such that when the inner wall is provided within the outer wall, the first volume is sealed between the outer wall and the inner wall at the opening of the outer wall at the proximal end of the outer wall. This further improves sealing the first volume from the second volume, thus reducing any risk of contamination.
  • the filter holder further comprising a filter mount for mounting the filter to the filter passage, the filter mount being connected to the distal end of the membrane such that when a filter is mounted by means of the filter mount, liquid that passes through the filter passage flows through the filter.
  • the filter mount is connected to the inner wall. With a rigid inner wall, a firm connection may be made between the filter and the inner wall, to seal off any openings between the first volume and the second volume, such that liquid can only flow from the first volume to the second volume via the filter, when mounted as specified.
  • the filter mount is releasably connected to the inner wall. This allows for replacement of the filter.
  • the filter mount comprises an opening for receiving liquid from the first volume and passing the liquid through the filter, when the filter is held by the filter mount.

For the avoidance of doubt, by virtue of the flexible nature of the membrane 210, the sizes of the second sub- volume and of the second volume may vary.
  • implementations of the first aspect may also be provided in which the membrane is able to adapt to changes of pressure of liquids in the volume and differences in pressures between the various volumes. This may be for example the case in an implementation in which the membrane has a rigidity that allows it to preserve a shape to provide the second volume, without the skeleton structure. Furthermore, an implementation may be envisaged in which the skeleton structure does not have a centre structure, like the drinking conduit 226. In such implementation, a skeleton structure may be provided with two, three, four or more members of the skeleton structure that provide structure and shape to the membrane to perform at least part of the functionality discussed above.
