Description

Interconnected Flow Control Mechanism

Field of the invention

The present invention is in the field of a dispensing system for a content held in a container, and of which the application for storage and dispensing of liquids is particularly interesting.

Background to the invention

The act of pouring from a conventional container can be challenging, laborious, and inefficient due to multiple reasons. The action of pouring from currently conventional containers with a single opening consists minimally of six phases: opening the cap, lifting the container, tilting the container (actual pouring), tilting back the container, putting back the container, and closing the cap. During the tilting and tilting back phases the container must be angled attentively and accurately to avoid spillage and control the flow speed. The tilting and tilting back phases must be repeated multiple times to appropriately assess the poured volume. Each repetition of tilting and tilting back increases the risk of spillage. Particularly the tilting and tilting back phases require adequate upper body strength meaning certain population groups are unable to properly pour. In currently conventional containers with a single opening the content does not exit in a steady and even flow, but in a series of abrupt "glugs". The glugging destabilises manual support of the container, and also causes splattering, so making steady pouring and spillage avoidance difficult.

In the art, the use of a funnel (e.g. patent US 5787944 A) or funnel attachment (e.g. patent US 6264072 B1 ) reduces the risk of spillage, but it has multiple disadvantages. The act of pouring remains elaborate with minimally six phases. The strenuous tilting back and forth remain necessary for the control of flow speed and volume assessment. They do not avoid the undesirable glugging effect. They are cumbersome, making the act of pouring more complex due to the presence of an extra component. There is an additional cost and effort to acquire a funnel or funnel attachment, and they require cleaning and protective storage.

A solution to the problem of glugging entails the addition of an air flow channel to the container which is directed towards an aerated part (e.g. patents US 500260 A, US 568921 A, US 577410 A, US 973616 A and US 3506167 A). An air flow channel may create a steadier flow with less splatter, however, multiple disadvantages remain. The act of pouring still remains elaborate with at least six phases. The necessary strenuous tilting back and forth for the control of flow speed and volume assessment remains unavoidable. Because the air flow channel is not an integrated part of the container, a separate production process is required for this component so adding at least one extra step to the production process. The attachment of the air flow channel to the container is technically challenging and makes the production process more complex. Aforementioned problems make the production of these inventions less economical and ecological compared to currently conventional containers. Another disadvantage is that the addition of an air flow channel reduces the opening through which content can exit. A disadvantage that is particularly present in air flow channels which have a small diameter, is that a hiss can be heard during pouring (air entering the container). The addition of an air flow channel in transparent containers can distort the design of the container and make it less appealing. The length of the air flow channel influences the pouring dynamics. Although short air flow channels (e.g. patents US 577410 A and US 3506167 A) require less production material and are thus more economical and ecological, complete reversal of the container is not possible because no air inflow is possible when the air flow channel is submerged. Because short secondary channels are adhered to one side of the container, tilting can only be performed in one way (with the air flow channel on the upside of the container). Compared to short air flow channels, long air flow channels (e.g. patents US 568921 A and US 973616 A) require more production material and are less economical and ecological. The addition of a long air flow channel in transparent containers distorts the container design more profoundly than short air flow channels. This can make the container look less appealing. With long air flow channels the bottom end of the container must be tilted highly during pouring in order to allow the internal end of the air flow channel to be in contact with the aerated part of the container.

US 6045013 A and US 6702160 B1 are attempts to simplify the act of pouring. These inventions offer means to open the outlet of a container in an inverted position (opening the outlet from the opposite side of the container). A closed inverted container can easily and accurately be positioned above a recipient opening. Once the container is positioned, the outlet can be opened to allow transfer of content. Although this concept simplifies the act of pouring by reducing the six necessary phases in currently conventional containers with a single opening to 4 phases (tilting and tilting back are eliminated), there remain multiple disadvantages with the solutions offered by US 6045013 A and US 6702160 B1 . US 6045013 A offers a means to open the outlet of a container in an inverted position, but there is no adequate venting possible. It is depicted that air should be able to pass between the cap and the neck of the container opening, but this is not sufficient to eliminate glugging, nor does it allow to control the extent of air inflow gradually, accurately or simultaneously with the other closure. Thus with this devices the problem of glugging is unsolved. Because the device described in US 6045013 A has multiple mechanical parts the risk of failure is high because of the accumulation of the risk of failure for each of the components. Because multiple components are necessary, the production and assembly of the container is technically challenging, time consuming and expensive. The device described in US 6702160 B1 attempts to solve multiple problems simultaneously, but it has multiple disadvantages. The control mechanism to open the outlet (plug) does not allow to control the flow speed gradually or accurately. Placing back the plug can be challenging because the movements of the closure mechanism in the container are unrestrained. Furthermore, although the proximal opening which contains the control handle can be opened entirely thus forming a venting hole, the extent of air inflow cannot be controlled gradually, accurately or simultaneously with the other closure. A partially unscrewed proximal cap might allow a limited amount of air inflow along the threads of the opening, but this does not suffice to eliminate glugging.

There is a need in the art for a container that improves the controllability of flow, addresses the problem of glugging and the aforementioned problems, and which is simple and cost-effective to manufacture.

It is to be understood that other embodiments may be utilised and structural or logical changes may be made without departing from the scope of the present invention. The following detailed description, therefore, is not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.

The present invention relates to a dispensing system. It is used for dispensing a content, such as any flowable matter. The dispensing system comprises a sealable container. The sealable container is provided with a first opening disposed with a first adjustable element configured to repeatably adjustably restrict the first opening. The sealable container is further provided with a second opening disposed with a second adjustable element configured to repeatably adjustably restrict the second opening. The first and second adjustable elements are synchronised and configured for gradual control of flowable matter through said first and second openings respectively. The synchronisation may be realised using a transmission element.

The dispensing system allows accurate, simultaneous and synchronised control of the adjustable elements, such that the openings of the container are accordingly controlled. If applied to a dispensing container, it avoids the use of a funnel because the respective container opening can easily and accurately be positioned above the recipient opening. The act of pouring is simplified and the strenuous tilting back and forth are not necessary; the container can remain upright. The system in all its variations can accurately and exquisitely control the flow speed without the problem of glugging. The simplicity of design allows economical and ecological mass production. It allows easy handling without the need for elaborate operating instructions. It creates a means to easily store and pour content.

The dispensing system may be provided in a stand-alone container, for instance, for controllably dispensing and storing flowable matter in a domestic or working environment. The dispensing system may be integrated into other systems, for instance, in engines or machines, in catering systems, engineering systems, healthcare systems, agricultural systems, in any system where the controlled flow of flowable matter is desirable. The content is any flowable matter. Content may be, for instance, fluid, liquid, gel, gas, powder. It may be air. Preferably it is a liquid. The container is any container configured for holding content. Typically a container comprises one or more walls referred to herein as the container wall that defines a void space in which the content is held. Where the content is a liquid, for instance, the container wall may be made substantially from a liquid impermeable substance such as polypropylene, polycarbonate, aluminium and the like. The form of the container may be any, for example essentially cuboid (e.g. rectangular cuboid, square cuboid), cylindrical, spherical and the like. The skilled person will understand that the most suitable material dimensions, wall thickness and form depend on the content and the usage. The container is sealable, it is preferably fluidically sealable to prevent the passage of fluid into or out of the container in the sealed condition.

The container may comprise one or more additional elements such as a neck, a fluid- carrying conduit, a handle.

The container wall is preferably divided into a base end and a top end and one or more side walls. The top end is typically orientated upwards when the container is dispensing. The base end is typically orientated downwards when the container is dispensing. The base end may be at least partially flat. The base end may provide a stable base for support e.g. for stable placement on a flat surface. The base end may indicate an orientation of the container in an upright position. It is within the scope of the invention that a side wall can also provide a stable base (see for instance FIG. 6). The top end may be provided with a carrying handle. A container side wall may be provided with a carrying handle (see for instance FIG. 6).

The first and second openings each connect the container void space with the outside of the container. They are provided in the wall of the container, or in a neck or other structure (e.g. bypass conduit) comprised in and in fluidic connection with the container void space. It is appreciated that a first opening may be a single opening or may be a plurality of openings which together function as a first opening. Similarly, it is appreciated that a second opening may be a single opening or may be a plurality of openings which together function as a second opening. The first opening may be disposed at the top end of the container. The second opening may be disposed at the base end. Typically content may be dispensed from an opening in the base end.

The first or second opening may be provided on a neck side wall or upper open end (see later below). The first or second opening may be provided on a conduit in fluidic connection with the container void space.

According to one aspect a side wall may contain the first and second openings disposed one towards the top end and one towards the base end (see for instance FIG. 6).

The first or second opening is configured for the flow of content. The first opening may be a vent, to allow the inflow of air. The second opening may be an outlet, to allow the outflow of content. The container may be invertable and the venting and outlet roles of the first and second openings may be reversed.

The profile (outer shape) of the first or second opening may take any shape, for instance, square, rectangular (see for instance FIGs. 4 and 10), circular (see for instance FIG. 7), circular segment, oval, triangular (see for instance FIG. 12). The profile of the first or second opening may be the same or different. The profile size of the first and second opening may be the same or may be different. For instance, the first opening can have a larger profile size compared with the second opening, or vice versa. The skilled person will appreciate that the respective sizes of the first or second opening can be altered so as to change the rate of exit of content from the container. There are several factors that can determine the optimum size and profile of the respective openings including container void space volume, properties of the content (e.g. viscosity in the case of a liquid), desired flow control, which the skilled person will appreciate. The first or second opening may comprise a plurality of discrete openings which can act as a particle filter or a flow modifier to achieve a certain flow pattern (e.g. disperse flow, sprinkle,...). There are several factors that can determine the optimum number, size and profile of the discrete openings including but not limited to the properties of the content (e.g. size of the particles that require to be filtered) and the desired flow type (e.g. disperse flow), which the skilled person will appreciate.

One opening may be disposed on the container top end and one disposed on the container base end. The geometric centres of the opening profiles may be aligned; a central axis of the respective geometric centres may be aligned. The container may comprise one or more necks. A neck is understood to have a hollow longitudinal body having an opening at either side. Typically, the neck is cylindrical, though other shapes are envisaged. A side wall of the neck refers to a body of the hollow longitudinal structure. A neck has at one end a neck base end connected to the container wall, and at the other end a neck upper end. The neck base open end is in fluidic connection with the container void space. A neck upper end may be provided with a fluidic coupling for attachment to a pouring conduit such as a spout, flexible hose, or elongated pipe.

A neck may assist with pouring from the container, for instance, to locate into a reciprocating vessel. A neck may protrude at least partially or fully outwards from the container, in particular from a container wall. A neck may protrude at least partially or fully inward into the container, in particular into a container wall. A neck may be disposed on the base end. A neck may be disposed on the top end. There may be two necks one disposed on the top end and one disposed on the base end, and a central axis of the respective necks may be co-axial. The neck body may be formed from the same material as the container wall.

According to one aspect, a container may comprise a neck at the top end that at least partially protrudes outwards from the container and a neck at the base end that at least partially protrudes inwards into the container (see for instance FIG. 4). According to one aspect, a container may comprise a neck at the top end that at least partially protrudes inwards into the container and a neck at the base end that at least partially protrudes outwards from the container (see for instance FIG. 8). According to one aspect, a container may comprise a neck at the top end that at least partially protrudes outwards from the container and a neck at the base end that at least partially protrudes outwards from the container (see for instance FIG. 7). According to one aspect, a container may comprise a neck at the top end that at least partially protrudes inwards into the container and a neck at the base end that at least partially protrudes inwards into the container.

A neck may be disposed with a first or second opening. A first or second opening may be disposed in a neck upper open end. A first or second opening may be disposed in a side wall of the neck. Where the first or second opening is provided on a neck side wall, the profile may be rectangular, the long side of the rectangle aligned with or perpendicular to a longitudinal axis of the neck. The first or second opening may overlap with the edge of the neck side wall. A first opening may be disposed on a first neck, and a second opening may be disposed on a second neck. Where a first or second opening is disposed on a neck, there may be no further first or second openings on the container wall. A neck may provide an attachment point, for a first or second adjustable element for instance. A neck may be threaded on an outer or inner wall. The threading allows repeatable adjustable restriction of the first or second opening by the first or second adjustable element, in particular when the first or second opening is provided on the side wall of the neck (see for instance FIGs. 2 and 4).

The type of thread can be selected according to the desired properties e.g. fine flow control, coarse flow control; the skilled person may select a suitable diameter, pitch and number of revolutions for instance.

A stop element may be provided on the neck wall to prevent removal when the first and/or second adjustable element is, for instance, a cap or a plug.

The first or second adjustable element may be disposed within the container void space or outside the container. For instance, in the example of FIGs. 4, 7 and 8, the second adjustable element (270) is within the container void, compared with the first adjustable element (230) disposed outside the container.

The container may comprise one or more bypass conduits. A bypass conduit is a hollow member having a body and a void space therein that is connected at one end towards the top end of the container and at the other end towards the base end of the container. The bypass conduit is preferably connected at either end to the side wall of the container. The void space of the bypass conduit is fluidically connected to the void space of the container. The void space of the bypass conduit is able to receive content, this can be particularly interesting for liquids. The volume of the bypass conduit void space is less than the volume of the container void space. The volume of the bypass conduit void space may be equal to or less than 0.25 of the volume of the container void space.

According to one aspect of the invention, the first and second openings are disposed on the bypass conduit (see for instance FIG. 6). The first opening may be disposed towards the top end of the conduit, and the second opening may be disposed towards the base end of the bypass conduit. The transmission element may be disposed within a void space of the bypass conduit. The neck structures described above may be provided on the bypass conduit instead of on the container wall. The base end of the neck would be in attachment to the bypass conduit. The first and second openings are then provided on the neck (e.g. side wall or open upper end). The bypass conduit may be made at least partially of a transparent or translucent material allowing it to act as a content level indicator. It may be provided with markings for gauging the volume of content remaining.

The bypass conduit may function as a carrying handle.

The bypass conduit may be dismountable from the container. This allows the bypass conduit to be reused, recycled, or allows the mounting of different bypass conduits, for instance, it may allow a user to select a rapid flow or fine controlled (slower) flow. The body of the container may be provided with reciprocating couplings to receive the dismountable bypass conduit.

The bypass conduit may be adapted for dismountable connection to a container with an air flow channel (see for instance FIG. 17). The air flow channel conducts venting air from or towards a top end of the container interior void.

The bypass conduit may be fitted with a transmission element provided with a partitioning body configured to prevent flow of content between the first and second opening via an interior void of the bypass conduit. The transmission element connecting the respective adjustable elements may be disposed in the interior void of the bypass conduit. The separating utility of the partitioning body may be for fluid or liquid.

The container may be made at least partially from a transparent or translucent material that can act as a content level indicator. The transparent or translucent material provides a window for viewing the level of the content. The container wall may be provided with markings for gauging the volume of content remaining. According to one aspect, a side wall, top end or base end of the container, preferably a longitudinal strip therein, is at least partially transparent or translucent (see for instance FIG. 6). The strip longitudinal axis may be parallel to a longitudinal axis of the transmission element. The strip longitudinal axis may be perpendicular to a longitudinal axis of the transmission element.

It is appreciated that the dispensing system of the invention may comprise one or more containers each with a first and second opening, and each with a first and second adjustable element, wherein movements of the first adjustable elements are synchronised with each other and movements of the second adjustable elements are synchronised with each other, and the first adjustable elements are synchronised with the second adjustable elements for gradual control of content flow through said first or second openings respectively. Where there are two or more containers, they may hold different content. Two or more containers may be rigidly connected to each other. Two or more containers may be linked such that the respective transmission elements are interconnected (see for instance FIG. 14), and are synchronised.

Two or more containers may be rigidly connected to each other. Two or more containers may be linked such that the openings through which the containers are linked comprises an intermediate adjustable element (see for instance FIG. 15). An intermediate adjustable element is configured to repeatably adjustably restrict the openings of the containers through which they are linked. By "restrict" it is meant restrict flow across the openings. The intermediate adjustable element may be synchronised with the first and second adjustable elements. In other words, movements of the intermediate adjustable element may be synchronised to movements of the first and second adjustable elements. The intermediate adjustable element may be connected to the same transmission element as the first and second adjustable elements. The intermediate adjustable element may have the same or similar properties or features to a first or second adjustable element described later below (e.g. may be a threaded closure, a sliding occluding body, a hinged occluding body and the like). The presence of the intermediate adjustable element allows the mixing of content between two containers.

A container of the dispensing system of the invention may comprise two or more compartments each with a first and second opening, and each with a first and second adjustable element, wherein movement of the first adjustable elements are synchronised with each other and movements of the second adjustable elements are synchronised with each other, and the first adjustable elements are synchronised with the second adjustable elements for gradual control of content flow through said first or second openings respectively. Where there are two or more compartments, they may be fluidically isolated. The compartments may hold different content.

It is an aspect of the invention that there is an interconnecting passage between two compartments, which interconnecting passage is disposed with an intermediate adjustable element (see for instance FIG. 16). An intermediate adjustable element configured to repeatably adjustably restrict the interconnecting passage. By "restrict" it is meant restrict flow across the opening. The intermediate adjustable element may be synchronised with the first and second adjustable elements. In other words, movements of the intermediate adjustable element may be synchronised to movements of the first and second adjustable elements. The intermediate adjustable element may be connected to the same transmission element as the first and second adjustable elements. The intermediate adjustable element may have the same or similar properties or features to a first or second adjustable element described later below (e.g. may be a threaded closure, a sliding occluding body, a hinged occluding body and the like). The presence of the interconnecting passage and complementary intermediate adjustable element allows the mixing of content between separated compartments.

A first adjustable element configured to repeatably adjustably restrict the first opening. The term "repeatably" in repeatably adjustably restrict means that the element is able to restrict and subsequently unrestrict the opening more than once, preferably several times. The term "adjustably" in repeatably adjustably restrict means that the extent of the restriction is gradual or quantitative, for instance, the opening may be set to any of 10%, 20%, 80% restricted. By "restrict" it is meant restrict flow across the opening. For instance, it may refer to restricting the flow of content or of venting air across the opening. In particular, it may refer to restricting the flow of air across the first opening and the exit of liquid from the second opening.

The first adjustable element is typically an occluding device configured to adjustably occlude the first opening. The second adjustable element is typically an occluding device configured to adjustably occlude the second opening. Generally speaking the first or second adjustable element is in sealing connection with the container wall, and may be displaced by translation or rotation to sealingly adjustably occlude the respective first or second opening.

The first adjustable element and/or second adjustable element are further configured to fluidically repeatably seal the first opening and/or second opening respectively. When the first opening and/or second opening is sealingly closed by the respective adjustable element, the content cannot flow across the opening. In such state, the content can be stored in the container. The first and second adjustable element are gradually movable (e.g. rotatable and/or displaceable) relative to the respective first and second opening. The extent of movement may be limited. For instance, a movement limiter may be provided on the first adjustable element and/or on the second adjustable element, and/or a movement limiter on the transmission element. The first and/or second adjustable elements may be non-dismountably attached to the sealable container. For instance, a stop element may be provided on a container neck wall to prevent removal when the first and/or second adjustable elements is a cap or a plug.

Where the container is provided with a threaded neck on which the first opening is disposed, the first adjustable element may be a threaded closure such as a threaded cap or plug configured to engage with the threaded neck and to adjustably restrict the first opening responsive to tightening or untightening of the threaded closure (see for instance FIGs. 4, 5, 7 and 8). By this action, the first adjustable element is displaced relative to the neck and opening thereon, and can completely or partially sealingly occlude first opening as rotation lifts or drops the first adjustable element.

Where the container neck disposed with a first opening is threaded on the outer wall, the threaded closure may be a threaded cap comprising a closed end and a cylindrical side wall extending therefrom disposed with a complementary inner threading (see for instance FIG. 7, first adjustable element 230). Where the container neck is threaded on the inside wall, the threaded closure may be a threaded plug comprising a closed end and a cylindrical side wall extending therefrom disposed with a complementary outer threading.

According to one aspect, the first opening is disposed on a side wall of the neck. In such case, the threaded closure may be an essentially cylindrical threaded closure having a closed end and a threaded side wall extending therefrom wherein the side wall is intact (i.e. no apertures), see for instance FIG. 4. The threaded closure may be, for instance, a threaded cap (i.e. threaded on an inner cylindrical wall).

According to another aspect, the first opening is disposed on an open upper end of the neck; there may be no opening in the side wall of the neck. In such case, the threaded closure may be an essentially cylindrical threaded closure having a closed end and a cylindrical side wall extending therefrom wherein the side wall contains an aperture, see for instance FIG. 7 and 8. The threaded closure may be, for instance, a threaded cap (i.e. threaded on an inner cylindrical wall, see for instance FIG. 7, first adjustable element 230). The threaded closure may be, for instance, a threaded plug (i.e. threaded on an outer cylindrical wall, see for instance FIG. 8).

Where the container is provided with a threaded neck on which the second opening is disposed, the second adjustable element may be a threaded closure such as a threaded cap or plug configured to engage with the threaded neck and to adjustably restrict the second opening responsive to tightening or untightening of the threaded closure (see for instance FIGs. 4, 5, 7 and 8). By this action, the second adjustable element is displaced relative to the neck and opening thereon, and can completely or partially sealingly occlude second opening as rotation lifts or drops the second adjustable element.

Where the container neck disposed with a second opening is threaded on the outer wall, the threaded closure may be a threaded cap comprising a closed end and a cylindrical side wall extending therefrom disposed with a complementary inner threading. Where the container neck is threaded on the inside wall, the threaded closure may be a threaded plug comprising a closed end and a cylindrical side wall extending therefrom disposed with a complementary outer threading (see for instance FIG. 7, second adjustable element 270). According to one aspect, the second opening is disposed on a side wall of the neck. In such case, the threaded closure may be an essentially cylindrical threaded closure having a closed end and threaded side wall extending therefrom wherein the side wall is intact (i.e. no apertures), see for instance FIG. 4. The threaded closure may be, for instance, a threaded cap (i.e. threaded on an inner cylindrical wall).

According to another aspect, the second opening is disposed on an open upper end of the neck; there may be no opening in the side wall of the neck. In such case, the threaded closure may be an essentially cylindrical threaded closure having a closed end and a cylindrical side wall extending therefrom wherein the side wall contains an aperture - see for instance FIGs. 7 and 8. The threaded closure may be, for instance, a threaded cap (i.e. threaded on an inner cylindrical wall). The threaded closure may be, for instance, a threaded plug (i.e. threaded on an outer cylindrical wall, see for instance FIGs. 7 and 8, second adjustable element 270). The profile (outer shape) of the aperture of the first or second adjustable element may take any shape, for instance, square, rectangular (see for instance FIG. 7), circular, circular segment, oval, triangular (see for instance FIG. 12). The profile of the aperture of the first or second adjustable element may be the same or different. The profile size of the aperture of the first or second adjustable element may be the same or may be different. For instance, the aperture of the first opening can have a larger profile size compared with the aperture of the second opening, or vice versa. The skilled person will appreciate that the respective sizes of apertures can be altered so as to change the rate of exit of the content from the container. There are several factors that can determine the optimum size and profile of the respective apertures including container void space volume, properties of the content (e.g. viscosity in the case of a liquid), desired flow control, which the skilled person will appreciate. The aperture of the first or second adjustable element may comprise a plurality of discrete apertures which can act as a particle filter or a flow modifier to achieve a certain flow pattern (e.g. disperse flow, sprinkle,...). There are several factors that can determine the optimum number, size and profile of the discrete apertures including but not limited to the properties of the content (e.g. size of the particles that require to be filtered) and the desired flow type (e.g. disperse flow), which the skilled person will appreciate.

Preferably, both the first and second adjustable elements are threaded closures. Appropriate seals may be provided to prevent flow of content or air through the thread, when the threaded closure is partially open.

A sealing closure may be further achieved by co-operation of a sealing rim and/or one or more sealing rings. A sealing ring or rim may be present on the first and/or second adjustable element that co-operates with the container wall or with a groove on the container wall. Alternatively or in addition, a sealing ring may be present on the container wall that co-operates with a rim or groove on the first and/or second adjustable element.

The skilled person will appreciate that the type of threading (e.g. diameter, pitch and number of revolutions, material) can influence displacement/turn of the adjustable element, amount of force required, level of stability, degree of flow control, compatibility of content, which can depend to some extent on the final application and content of the dispensing system, and he can understand how to suitably configure the dispensing system accordingly. The first adjustable element may be a hinged occluding body. The second adjustable element may be a hinged occluding body. Preferably both the first and second adjustable elements are hinged occluding bodies. Possibly the hinged occluding body is an occluding closure for respective first or second opening, and is attached by a hinge to the container wall. The axis of rotation of the hinge may be parallel to an outside wall of the container. The hinged occluding body is configured to adjustably occlude the respective first or second opening by rotation thereof (see for instance FIG. 10). The hinged occluding body may have a rectangular outer profile. Appropriate seals may be provided to prevent flow of content or air through a gap between the hinged cover and the respective opening in the closed condition.

The skilled person will appreciate that the type of hinged occluding body (e.g. thickness, size, material) can influence amount of force required, level of stability, degree of flow control, compatibility of content, which can depend to some extent on the final application and content of the dispensing system, and he can understand how to suitably configure the dispensing system accordingly.

The first adjustable element may be a slidable occluding body. The second adjustable element may be a slidable occluding body. Preferably both the first and second adjustable elements are slidable occluding bodies.

Typically the slidable occluding body is a flat plate in slidable co-operation with a flat surface of the container wall. The slidable occluding body may be disposed on the inside or outside of the container. The slidable occluding body may be fixed by a revolute connection onto the container wall and configured to slidably adjustably occlude the opening by rotation thereof (see for instance FIG. 12). According to a preferred aspect, the slidable occluding body has an occluding body containing an aperture that can be brought adjustably into alignment with the respective first or second opening. The slidable occluding body may have a circular outer profile. Appropriate seals may be provided to prevent flow of content or air through a gap between the slidable occluding body and the container wall.

The skilled person will appreciate that the type of slidable occluding body (e.g. thickness, diameter, aperture size, material) can influence amount of force required, level of stability, degree of flow control, compatibility of content, which can depend to some extent on the final application and content of the dispensing system, and he can understand how to suitably configure the dispensing system accordingly.

The first and second adjustable elements are synchronised. Movement of one of the first and second adjustable elements is accompanied by a proportional adjustment or movement of the other adjustable element. The terms "adjustment" and "movement" are used interchangeable herein, and refer to a movement by a first or second adjustable element relative to the corresponding first or second opening. The movement may be to the same extent (in the case of a direct connection between the first and second adjustable element) or to a different extent (in the case of a mechanical leverage between the first and second adjustable element). The movement may be a displacement and/or a rotation.

Synchronisation of movement is achieved using a transmission element connected to the first and second adjustable elements configured to synchronise adjustment of the first and second adjustable elements. The transmission element may be a stiff longitudinal element in rigid connection with the first and second adjustable elements. In particular, each of the ends of the stiff longitudinal element is in rigid connection with the respective first and second adjustable elements. Such transmission element is apt when the synchronised movement is a rotation, in particular where the axis of rotation passes through the container void space. It might in particular be apt when the first and second adjustable elements are each threaded closures.

The transmission element may be a stiff longitudinal element in hinged (revolute) connection with the first and second adjustable elements; such transmission element is apt when the synchronised movement of the first and second adjustable elements are each hinged with respect to the container wall.

The transmission element may contain one or more additional components to provide a mechanical leverage. The mechanical leverage refers to an amplification or attenuation of movement of one of the first and second adjustable elements responsive to movement of the other adjustable element. For instance, a mechanical leverage of 1 :2 might result in a movement of 2 distance units by the second adjustable element responsive to a movement of 1 distance unit by the first adjustable element. Mechanical leverage may be achieved by means known in the art, for instance using one or more levers, gears, pulleys, and the like. The transmission element may be provided with one or more partitioning bodies configured to separate the first opening and the second opening, which partitioning body is disposed in fixed relation to the transmission element.

The first and second adjustable elements are actuated by the application of force. An adjustment to the first adjustable element changes the restriction to the first opening and synchronously changes the restriction to the second opening. Where a liquid is dispensed, the rate of ingress of venting air into the first opening is controlled by the restriction extent to the first opening which can be adjusted. At the same time the rate of exit of content is adjusted depending on the adjustment applied to the first opening. Thus a decrease in the restriction to the first opening (i.e. increase flow) is accompanied by a synchronous decrease in the restriction to the second opening. Control of flow across both openings not only allows an exquisite control of content flow, but also prevents the glugging effect.

Filling of a container may be performed through multiple ways. For instance, an adjustable element may be provided with a sealable filling port. The container body may be provided with a sealable filling port. The container may be filled by rotating the container in such a way that the filling openings are above the level of content, and the container is filled through one or more of the openings. After the container is filled and the ports sealed, the container be manipulated freely.

The container top end (112) comprises an externally protruding (first) neck (132); the first opening (130) is located at a neck side wall (FIG. 1 ). The container base end (114) is provided with an internally protruding (second) neck (172); the second opening (170) is located at a neck side wall. The first (130) and second (170) openings each have rectangular profiles. The first (130) and second (170) openings each have four sides, i.e. the opening is bound by the respective neck side walls. The first adjustable element (230) is a cylindrical closure configured to engage with the first neck (132). The second adjustable element (270) is cylindrical closure configured to engage with the second neck (172). Both first (230) and second (270) adjustable elements are rigidly connected to a rod-like transmission element (210). The cylindrical side walls of the first and second adjustable elements are intact i.e. they contain no apertures. The first adjustable element is provided with a control handle (236) for manual actuation of the first adjustable element. Moving the first adjustable element (230) upwards gradually exposes the first and second openings directly, thereby reduces a restriction of the first and second openings respectively.

FIG. 4 illustrates an example of a dispensing system (100) of the invention. For clarity the container (110) is shown separated from the assembly of first (230) and second (270) adjustable elements and rod-like transmission element (210). The container top end (112) comprises an externally protruding (first) neck (132); the first opening (130) is located at a neck side wall. The container base end (114) is provided with an internally protruding (second) neck (172); the second opening (170) is located at a neck side wall. The first neck (132) at the container top end contains an outer thread (134). The second neck (172) at container base end (114) also contains an outer thread (174). The first (130) and second (170) openings each have rectangular profiles. The first (130) and second (170) openings each have four sides, i.e. the opening is bound by the respective neck side walls. The first adjustable element (230) is a cylindrical closure and has an inner thread that engages the outer thread (134) of the first neck (132). The second adjustable element (270) is a cylindrical closure and has an inner thread (272) that engages the outer thread (174) of the second neck (172). Both first (230) and second (270) adjustable elements are rigidly connected to a rod-like transmission element (210). The cylindrical side walls of the first and second adjustable elements are intact i.e. they contain no apertures. The first adjustable element is provided with a control handle (236) for manual rotation of the first adjustable element (230). The control handle (236) is serrated (238) to facilitate manual application of torque. Turning the first adjustable element (230) anticlockwise gradually exposes the first and second openings directly, thereby reduces a restriction of the first and second openings respectively.

FIG. 5 is a cross-sectional view of the dispensing system (100) of FIG. 4 in a closed (fluidically sealed) configuration by virtue of the first and second adjustable elements. FIG. 6 illustrates another exemplary dispensing system (100) of the invention wherein the container (110) comprises a bypass conduit (120). The bypass conduit (120) is connected at either end to the container side wall. The container is shown in a stable position resting on a container side wall. Container top end (112) and base end (114) resume their operating orientation prior to dispensing when the container is rotated. The bypass conduit (120) towards the container top end (112) comprises a threaded (first) neck (132) disposed with the first opening. The first adjustable element (230) - a threaded occluding body or closure - is engaged in the threaded first neck (132). The bypass conduit (120) towards the container base end (114) comprises a threaded (second) neck (172), disposed with the second opening. The second adjustable element (270) - a threaded occluding body or closure - is engaged in the threaded second neck (172). The transmission element (210) connecting the respective adjustable elements (230 and 270) is disposed in the interior void of the bypass conduit (120). The container wall at the top end (112) is transparent in a strip region (116) which acts as a level gauge when the container is resting on a side wall. The container wall at a side wall is transparent in a strip region (118) which acts as a level gauge when the container is resting on the base end or when it is orientated for dispensing.

FIG. 7 illustrates an exemplary dispensing system (100) of the invention. For clarity the container (110) is shown separated from the assembly of first (230) and second (270) adjustable elements and rod-like transmission element (210). The container top end (112) comprises an externally protruding (first) neck (132) without side opening; the first opening (130) is located at a first neck upper open end. The side wall of the first neck is intact i.e. it contains no openings. The container base end (114) is provided with an externally protruding (second) neck (172) also without side openings; the second opening (170) is located at a second neck upper open end. The first neck (132) at the container top end (112) contains an outer thread (134). The second neck (172) at the container base end (114) contains an inner thread (174). The first adjustable element (230) is a cylindrical closure and has an inner thread that engages the outer thread (134) of the first neck (132). The second adjustable element (270) is a cylindrical closure and has an outer thread (272) that engages the inner thread (174) of the second neck (172). Both first (230) and second (270) adjustable elements are rigidly connected to a rod-like transmission element (210).

There are two apertures (234) on the first adjustable element (230) cylindrical side wall and two apertures (274) on the second adjustable element (270) cylindrical side wall; the apertures have rectangular profiles. The apertures have four sides, i.e. the aperture is bound by the respective cylindrical side walls. The first adjustable element is provided with a control handle (236) for manual rotation of the first adjustable element. The control handle (236) is serrated (238) to facilitate manual application of torque. Turning the first adjustable element (230) anticlockwise gradually exposes the apertures disposed on the first and second adjustable elements, which in turn reduces a restriction of the first and second openings respectively.

FIG. 8 illustrates another exemplary dispensing system (100) of the invention. For clarity the container (110) is shown separated from the assembly of first (230) and second (270) adjustable elements and rod-like transmission element (210). The container (110) top end (112) comprises an internally protruding (first) neck (132) without side opening; the first opening (130) is located at a first neck upper open end. The side wall of the first neck is intact i.e. it contains no openings. The container base end (114) is provided with an externally protruding (second) neck (172) also without side opening; the second opening (170) is located at a second neck upper open end. Both first (132) and second (172) necks contain an inner thread (134 and 174). The first adjustable element (230) is a cylindrical closure and has an outer thread (232) that engages the inner thread (134) of the first neck (132), similarly, the second adjustable element (270) is a cylindrical closure and has an outer thread (272) that engages the inner thread (174) of the second neck (172), both first (230) and second (270) adjustable elements are rigidly connected to a rod-like transmission element (210).

There are two apertures (234) on the first adjustable element (230) cylindrical side wall, and two apertures (274) on the second adjustable element (270) cylindrical side wall, and they have rectangular profiles. The apertures each have three sides, i.e. they are open on one side. The first adjustable element is provided with a control handle (236) for manual rotation of the first adjustable element. The control handle (236) is serrated (238) to facilitate manual application of torque.

FIG. 9 depicts exemplary first and second adjustable elements connected to a rod-like transmission element, separated from the container. The apertures (234 and 274) of the respective first (230) and second adjustable element (270) have four sides, i.e. the aperture is bound by the respective cylindrical side walls.

FIGs. 10 and 11 illustrate another example of a dispensing system (100) according to the invention. The container top end (112) is essentially planar and comprises the first opening (130). The container base end (114) is similarly planar and comprises the second opening (170). The openings (130 and 170) each have a rectangular profile. The first adjustable element (230) comprises a hinged closure, attached via a hinge joint (239) to the container top end (112). The second adjustable element (270) is a hinged closure, attached via a hinge joint (279) to the container base end (114). Connecting the first adjustable element (230) to the second adjustable element (270) is a rod-like transmission element (210).

The first (130) and second (170) openings may gradually be opened through manipulation of the first (230) and/or second (270) adjustable elements that are hinged closures whose movements are synchronised. The hinged closures may rotate in either direction respective to the container (e.g. externally or internally). It is apparent that by moving one hinged closure in either direction (externally or internally), the other hinged closure also moves responsively. If the container contains content in a liquid state, and the first opening (130) is orientated upwards, opening of the first adjustable element (230) concomitantly opens the second adjustable element (270), and simultaneously liquid exits through the second opening (170), while air is allowed to flow in the container through the first opening (130). This synchronous transfer of content eliminates glugging. One or more of the first adjustable element (230), second adjustable element (270), the first (130) and second (170) openings may be disposed with additional components (e.g. a spring) configured to bias the first adjustable element (230) and second adjustable element (270) in a closed or open position. A springing back into a closed or open position can further simplify the act of pouring (semi-automatic closure).

FIGs. 12 and 13 are another example of a dispensing system (100) of the invention. The container top end (112) is essentially planar and comprises the first opening (130). The container base end (114) is similarly planar and comprises the second opening (170). The openings (130 and 170) have a triangular profile. The first adjustable element (230) is a sliding closure, attached via a revolute joint to the container top end. The second adjustable element (270) is a sliding closure, attached via a revolute joint to the container base end (114). The first (230) and second (270) adjustable elements are disc-shaped and contain an aperture (234 and 274) that can at least partially coincide with the openings (130 and 170) on the container. Connecting the first adjustable element (230) to the second adjustable element (270) is a rod-like transmission element (210) that transmits torque.

The container openings (130 and 170) may gradually be exposed through manipulation of the first or second adjustable element (230 and 270). When the apertures (234 and 274) of the first (230) and second (270) adjustable elements are aligned with the first (130) or second (170) container openings, content can flow. Rotating the first (230) or second (270) adjustable element away from the container openings (130) and (170) stops content flow. If the container (110) is filled with content in a liquid state, and the aperture (234) of the first adjustable element (230) is orientated upwards, aligning the apertures (234 and 274) of the first (230) and second (270) adjustable elements with the respective container openings (130 and 170) simultaneously allows liquid to exit through the second opening (170), while air is allowed to flow in the container through the first opening (130). This synchronous transfer of content eliminates glugging. FIG. 14 is an example of a dispensing system of the invention having two containers (110' and 110"). Each container (110' and 110") is disposed with a first opening provided with a first adjustable element (230' and 230") and a second opening provided with a second adjustable element (270' and 270"). Connecting each first adjustable element (230' and 230") to the second adjustable element (270' and 270") is a rod-like transmission element (210' and 210") that transmits force. The respective rod-like transmission elements (210' and 210") are interconnected by an interconnecting transmission element (212) disposed in rigid relation to the respective transmission elements (210' and 210"). Movements of the first adjustable element (230') of the upper container (110') are synchronised with movements of the second adjustable element (270') of the upper container (110') by the upper rod-like transmission element (210'). Movements of the first adjustable element (230") of the lower container (110") are synchronised with movements of the second adjustable element (270") of the lower container (110") by the lower rod-like transmission element (210"). Movements of the first adjustable element (230') of the upper container (110') are synchronised with movements of the first adjustable element (230") and second adjustable element (270") of the lower container (110") by the interconnecting transmission element (212).

FIG. 15 is an example of a dispensing system of the invention having two containers (110' and 110"). Each container (110' and 110") is disposed with a first and second opening. The two containers (110' and 110") are fluidically isolated but fluidically connected by an interconnecting passage. The first opening of the first container (110') is provided with a first adjustable element (230) and the second opening of the second container (110") is provided with a second adjustable element (270). Connecting the first adjustable element (230) to the second adjustable element (270) is a rod-like transmission element (210) that transmits force. The interconnecting passage is disposed with an intermediate adjustable element (290), connected to the transmission element (210). Movements of the intermediate adjustable element (290) are synchronised to movements of the first (230) and second (270) adjustable elements.

FIG. 16 is an example of a dispensing system (100) of the invention. The container (110) is disposed with two compartments (111 ' and 111 ") fluidically isolated but fluidically connected by an interconnecting passage. The first opening is provided with a first adjustable element (230) and a second opening provided with a second adjustable element (270). Connecting the first adjustable element (230) to the second adjustable element (270) is a rod-like transmission element (210) that transmits force. The interconnecting passage is disposed with an intermediate adjustable element (290), connected to the transmission element (210). Movements of the intermediate adjustable element (290) are synchronised to movements of the first (230) and second (270) adjustable elements.

FIG. 17 is an example of a dispensing system (100) of the invention in which the container (110) is provided with an air flow channel (300). The air flow channel (300) is configured to conduct air towards a top end (112) of the container in an operating orientation. The bypass conduit (120) is adapted for dismountable connection to the container with the air flow channel (300). The container (110) is shown in a stable position resting on a container side wall. Container top end (112) and base end (114) resume their operating orientation prior to dispensing when the container is rotated, in this case 90 degrees anticlockwise, such that it is supported by the base end (114). The bypass conduit (120) is provided at one end with a first opening and a first adjustable element (230) configured to repeatably adjustably restrict the first opening. The bypass conduit is provided at the other end with a second opening and a second adjustable element (270) configured to repeatably adjustably restrict the second opening. The bypass conduit (120) is further provided with a pair of ports (122, 124) that fluidly connect with a complementary pair of ports (302, 304) on the container. The bypass conduit (120) ports (122, 124) are provided at either end of the bypass conduit. A first bypass port (122) is configured for the passage of air from the first opening into the air flow channel. The second bypass port (124) is configured for the passage of content out of the container (110) through the second opening. Connecting the first adjustable element (230) to the second adjustable element (270) is a rod-like transmission element (210) that transmits force. The transmission element (210) is fitted with a partitioning body (310) configured to prevent flow of content between the first and second opening, in particular between the bypass conduit (120) ports (122, 124) via an interior void of the bypass conduit (120). The transmission element (210) connecting the respective adjustable elements (230 and 270) is disposed in the interior void of the bypass conduit (120).

The present dispensing system provides a means to easily store and pour content. It allows regulation of a precise transfer of content without spillage. The act of pouring is simplified and the strenuous tilting back and forth which are necessary in currently conventional containers are eliminated. It allows the control of multiple openings, and in containers it can thus simultaneously create a vented opening while also opening an outlet. This synchronous opening eliminates the glugging of content in a liquid state during pouring. The simplicity of the design allows an easy application to containers, and an economical and ecological mass production of such containers is possible with currently available techniques.

With the practices of a skilled person, the invention envisages variations including but not limited to number, size, material, shape, colour, placement and placement relative to other components of all the components of the invention including but not limited to the container, container opening, neck, thread of the neck, adjustable element, thread of the adjustable element, transmission element, control handle of the closure, aperture of the adjustable element, container handle, container bypass conduit, container volume indicator, container air flow channel, partitioning body of the transmission element.
