A FLEXIBLE CONTAINER FOR STORING AND DISPENSING A FLOWABLE
SUBSTANCE
Field of the Invention
The present invention relates to a flexible container for storing and dispensing a flowable substance. Particularly, but not exclusively, the present invention relates to a flexible self-supporting container for storing and dispensing a flowable substance, particularly, but not exclusively, a drink or flowable food. The present invention also relates to methods of passing a flowable substance out of the flexible container, a method of passing a flowable substance into the flexible container and a method of manufacture of the flexible container.
Background of the Invention
A known container for storing and dispensing a liquid (typically wine) is a flexible pouch comprising front and rear sheets, formed by flexible sheets, that are attached to each other to define an internal chamber for storing the liquid. A tap is provided towards a lower side of the container, mounted in an aperture in the front sheet. However, due to the need to securely attach the tap in the front sheet, it is necessary to mount the tap at a location above the lower side of the container .
When the tap is opened, the liquid drains from the chamber out of the tap. However, because the tap is mounted at a location above the lower side of the container, the portion of the liquid below the level of the tap (below the level of the tap inlet) does not pass out of the tap and remains in the chamber.
It can be difficult, or impossible, to remove this remaining liquid from the chamber.
The present invention seeks to address or mitigate at least some of the above mentioned problems. Alternatively, or additionally, the present invention seeks to provide an improved flexible container for storing and dispensing a flowable substance. Alternatively, or additionally, the present invention seeks to provide an improved method of passing a flowable substance out of a flexible container. Alternatively, or additionally, the present invention seeks to provide an improved method of passing a flowable substance into a flexible container. Alternatively, or additionally, the present invention seeks to provide an improved method of manufacture of a flexible container for storing and dispensing a flowable substance.
Summary of the Invention
According to a first aspect of the invention there is provided a flexible container for storing and dispensing a flowable substance, the container comprising:
first and second flexible sheets attached to each other to define a chamber therebetween, for storing a flowable substance;
wherein the container comprises a first outlet member, for passing a flowable substance out of the chamber, mounted in an opening between the first and second sheets, and a second outlet member, for passing a flowable substance out of the chamber, mounted in an opening of the container .
The feature of the first and second outlet members is advantageous in that it may facilitate emptying of the chamber.
In this regard, it may allow for some, or all, of any flowable substance that is unable to pass out of the chamber through one of the outlet members, to pass out of the chamber through the other outlet member.
For example, when the container is positioned in a certain orientation (e.g. vertically) so that some of the flowable substance passes out of the chamber through one of the outlet members (e.g. the second outlet member) under gravity alone, it may be that not all of the flowable substance is able to pass out of that outlet member, for example the flowable substance that is below the level of the outlet member. The provision of the other outlet member (e.g. the first outlet member) may allow for the orientation of the container to be changed (e.g. the container may be turned upside down) so that the remaining flowable substance passes out of the chamber through that other outlet member (e.g. the first outlet member).
Furthermore because the first outlet member is mounted in an opening between the first and second sheets, this may further facilitate the emptying of the chamber. In this regard, it may prevent, or reduce, the flowable substance from being retained at an interface between the first and second sheets, for example at or near where the first and second sheets are attached to each other (e.g. in folds in the first or second sheets at the interface).
There is therefore a synergy between providing a first outlet member mounted in an opening between the first and second sheets, and a second outlet member mounted in an opening of the container, since these features may combine to facilitate the emptying of the chamber.
Also, the first outlet member may allow for the emptying of the container to be performed in a relatively controlled manner (compared to if there was no first outlet member mounted in the opening). Furthermore, the first outlet member may allow for a controlled, but relatively fast, emptying of the container.
Also, one of the outlet members may allow air into the chamber as the flowable substance passes out of the chamber through the other outlet member. This may prevent a vacuum forming in the chamber, as the flowable substance passes out of the chamber, thereby allowing for an increased rate of emptying of the container.
It will be appreciated that the first and second outlet members are distinct from each other, i.e. they are not formed by the same member.
In embodiments of the invention the first and second outlet members are configured to pass the flowable substance, from the chamber, out of the container.
Optionally the first and/or second outlet members is/are configured to pass a flowable substance from the exterior of the container to the chamber.

Detailed Description
Referring to Figures 1 to 6 there is shown a container 1 according to an embodiment of the present invention.
The container 1 is flexible and comprises front and rear flexible sheets 2, 3 of material. The container also comprises a third flexible sheet of material in the form of a base 4 (see Figure 6).
Each of the front and rear sheets 2, 3 extends in a width direction between first and second sides 5, 6 and in a height direction between a lower side 7 and upper sides 8, 9, 10.
The container 1 is flexible, but is rigid enough to be selfsupporting (described in more detail below). In the currently described embodiment the material of the front and rear sheets 2, 3 and of the base 4, is a composite laminate of polyethylene terephthalate (commonly referred to as PET, sometimes PETE), polyethylene (commonly referred to as PE) and nylon, specifically PET12/NY25/PE160. However, any suitable material that is flexible, impermeable to fluids and rigid enough to allow the container to be self-supporting (see below) may be used).
The front and rear sheets 2, 3 and the base 4 each have a thickness of 197 microns. It will be appreciated that any suitable thickness may be used that allows the container to be flexible (i.e. flexible enough to allow the container to be folded when empty), impermeable to fluids and rigid enough to allow the container to be self-supporting (see below).
Preferably the front and rear sheets 2, 3 and the base 4 have a thickness that is greater than or equal to 100 microns and less than or equal to 300 microns.
The front and rear sheets 2, 3 are attached to each other, at their periphery, along substantially the entire length of their first and second sides 5, 6 to form first and second sides 5', 6' of the container 1. The container 1 extends in a width direction between its first and second sides 5' , 6' .
Each of the front and rear sheets 2, 3 is attached, at its periphery, along substantially the entire length of its lower side 7, to the outer periphery of the base 4, to form a lower side 7' of the container 1. The base 4 is foldable inwardly to allow the container 1 to collapse. The base 4 is a gusset.
The front and rear sheets 2, 3 are also attached to each other, at their periphery, along substantially the entire length of their upper sides 8, 9, 10, apart from at an opening 14 (see below), to form upper sides 8', 9', 10' of the container 1.
The container 1 extends in a height direction between its lower side 7' and its upper sides 8', 9', 10'. The container 1 extends in a depth direction between its front and rear sheets 2, 3.
The first and second sides 5' , 6' of the container 1 are substantially parallel to each other and the lower side 7' is substantially perpendicular to the first and second sides 5', 6'. The upper sides 8', 9', 10' comprise a first upper side 9' that is substantially parallel to the lower side 7' and second and third upper sides 8', 10' that are disposed either side of the first upper side 9' (in the width direction). The second and third upper sides 8' , 10' are inclined at an oblique angle relative to the first upper side 9' and relative to the first and second sides 5', 6' of the container 1.
It will be appreciated that the front and rear sheets 2, 3, are attached to each other along their upper sides, i.e. there is no 'base' at the upper side. In this regard, the width of the container 1 decreases towards the upper side of the container 1. In the orientation shown in Figures 1 to 6, the container is in an upright vertical orientation, which is the orientation it is intended to be in when standing on its base 4 ready for use. In this orientation, the first and second sides 5', 6' of the container 1 are substantially vertical and the base 4 is substantially horizontal.
In the currently described embodiment the front and rear sheets 2, 3 are attached to each other, and to the base 4, along said peripheries, by heat sealing. This provides a fluid tight attachment between the respective sheets. However, it will be appreciated that any suitable means of attachment may be used, including welding or gluing for example.
In this respect, the front and rear sheets 2, 3 are attached to each other, and to the base 4, by said heat sealing, along an attachment interface 20. The attachment interface 20 is the path along which the front and rear sheets 2, 3 are attached to each other, and to the base 4.
The container 1 is hollow. In this regard, an internal chamber 11 is defined between the front and rear sheets 2, 3 and the base 4 (in Figure 1 a portion of the front sheet 2 is cut away for illustrative purposes, to show the chamber 11). It will be appreciated that the attachment interface 12 forms the outer periphery of the chamber 11. The chamber 11 is for containing a flowable substance 12. The container 1 forms a substantially sealed enclosure (when the first and second outlet members 13, 15 are closed- see below) that is impermeable to fluids.
A flowable substance 12 is shown contained in the chamber 11. In the currently described embodiment the flowable substance 12 is a liquid in the form of wine. However, the flowable substance may be of any form, including any liquid (e.g. other alcoholic or non-alcoholic drinks or other liquids) or flowable solid (e.g. food puree) . It will be appreciated that the container may be provided empty, i.e. without the flowable substance in it.
The container 1 comprises a first outlet member 13 that fluidly connects the internal chamber 11 to the exterior of the container 1, for passing the flowable substance 12 out of the chamber 11 (and out of the container 1).
The first outlet member 13 is mounted in an opening 14 provided between the front and rear sheets 2, 3. The opening 14 is provided by a gap in the attachment interface 20. In this respect, the opening 14 is provided by a gap in the attachment of the front and rear sheet 2, 3, i.e. a location along the periphery of the container 1 where the front and rear sheets are not attached to each other (or to the base 4) . The opening 14 extends inwardly from the exterior of the container 1 to the chamber 11. The opening 14 is defined by opposed internal surfaces of the front and rear sheets 2, 3. The opening 14 does not pass through either the front or rear sheets 2, 3, but passes between them.
Similarly, the first outlet member 13 does not pass through either the front or rear sheets 2, 3, but passes between them.
The first outlet member 13 (and the opening 14) is provided in the second upper side 8' of the container 1. In this regard, the first outlet member 13 is mounted in a corner region of the container 1.
The front and rear sheets 2, 3 are attached to each other along substantially the length of that side 8' of the container, apart from at the opening 14.
The first outlet member 13 comprises a spout 13a and an attachment portion 13b (shown as a dotted outline in Figure 2) . The attachment portion 13b is a gland. The attachment portion 13b is attached to the inner end of the spout 13a and extends radially outwardly from the inner end. The attachment portion 13b is mounted in the opening 14 and is fixedly attached in the opening. In this regard, the attachment portion 13b is bonded (e.g. melted or glued) to the inner surfaces of the front and rear sheets 2, 3 that define the opening 14. The attachment portion 13b has a longitudinal axis that is substantially parallel to the plane of the interface of the front and rear sheets 2, 3.
The first outlet member 13 forms a sealed fit in the opening 14, with the internal surfaces of the front and rear sheets 2, 3 forming a seal around the attachment portion 13b. The seal is a fluid-tight seal.
The spout 13a protrudes outwardly past the opening 14 (i.e. outwardly past the plane of the opening 14, into the external surroundings of the container 1). In this regard, the spout 13a protrudes outwardly past that side 8' of the container 1 that it is mounted on.
The spout 13a has the shape of a hollow tube.
The spout 13a is rigid. In this regard, the spout 13a is rigid enough that it does not deform under its own weight.
The spout 13a and attachment portion 13b together define an internal conduit 13c that fluidly connects the chamber 11 to the external surroundings of the container 1 (see Figure 2). The conduit 13c has an inlet 13i, located where the conduit 13c meets the chamber 11, and an outlet 13d, located at the outer end of the spout 13a. The inlet 13i and outlet 13d form the inlet 13i and outlet 13d of the first outlet member 13.
The conduit 13c has a circular cross-sectional shape that decreases slightly in radius towards the outlet 13d. This may allow for an increase in the control of the pouring of the flowable substance 12 out of the outlet member 13.
The first outlet member 13 has an exit direction El (see Figure 2), which is the direction that the flowable substance 12 passes out of the outlet 13d. In this regard, the exit direction El is the outward direction along the longitudinal axis of the conduit 13c, at the outlet 13d.
The first outlet member 13 is selectively openable and closable. In the current embodiment the first outlet member 13 comprises a screw cap 13e (shown in Figure 1, mounted on the spout 13a to close the outlet member 13, but omitted from the other Figures) that can be screwed onto, and unscrewed from, the spout 13a to close and open the first outlet member 13 respectively. It will be appreciated that any suitable means of opening and closing may be used, including by a push-pull spout, or a hinged lid for example.
In this regard, the outlet member 13 is configured such that when the first outlet member 13 is closed, the flowable substance 12 may not pass through the outlet member 13, through its conduit 13c, (in either direction) and when the first outlet member 13 is open, the flowable substance 12 may pass through the outlet member, through its conduit 13c (i.e. from the chamber 11, through the outlet member 13 and out of the container 1, and vice versa).
The outlet member 13 is configured such that when the first outlet member 13 is closed, air may not pass through the outlet member 13, through its conduit 13c, (i.e. from the external surroundings into the chamber 11) and when the first outlet member 13 is open, air may pass through the outlet member 13, through its conduit 13c (i.e. from the external surroundings into the chamber 11).
The container 1 also comprises a second outlet member 15 that fluidly connects the internal chamber 11 to the exterior of the container 1, for passing the flowable substance 12 out of the chamber 11 (and out of the container 1).
The second outlet member 15 is mounted at a lower location on the container than the first outlet member 13 (i.e. a lower location when the container mounted on its base 4, is in its upright configuration).
The second outlet member 15 is mounted in an opening 16 provided in the front sheet 2. In this regard, the opening 16 passes through the front sheet 16 (i.e. through the thickness of the front sheet 16) .
The second outlet member 15 comprises a tap 15a and an attachment portion 15b. The attachment portion 15b is a gland. The attachment portion 15b is attached to the inner end of the tap 15a and extends radially outwardly from the inner end. The attachment portion 15b is mounted in the opening 16 and is fixedly attached in the opening 16. In this regard, the attachment portion 15b is bonded (e.g. melted or glued) to the inner surface of the front sheet 2 that defines the opening 16.
The second outlet member 15 forms a sealed fit in the opening 16, with the internal surface of the front sheet 2 forming a seal around the attachment portion 15b. The seal is a fluid-tight seal.
The tap 15a protrudes outwardly past the opening 16 that it is mounted in. In this regard, the tap 15 protrudes outwardly past the sheet 2 of the container 1 that it is mounted on.
The tap 15a extends outwardly from the attachment portion 15b. The tap 15a has the shape of a hollow, generally rightangled, tube. The tap 15a is rigid. In this regard, the tap 15a is rigid enough that it does not deform under its own weight.
The tap 15a and attachment portion 15b together define an internal conduit 15c that fluidly connects the chamber 11 to the external surroundings of the container 1 (see Figure 2) . The conduit 15c has a generally circular cross-sectional shape. The conduit 15c has an inlet 15i, located where the conduit 15c meets the chamber 11, and an outlet 15d, located at the outer end of the tap 15a. The inlet 15i and outlet 15d form the inlet 15i and outlet 15d of the second outlet member 15. The inlet 15i is located above the level of the lower surface 7' of the container 1 (when the container 1 is in its vertically upright orientation). In this regard, the inlet 15i is located above the level of the base 4.
The second outlet member 15 has an exit direction E2 (see Figure 2), which is the direction that the flowable substance 12 passes out of the outlet 15d. In this regard, the exit direction E2 is the outward direction along the longitudinal axis of the conduit 15c at the outlet 15d.
The second outlet member 15 is selectively openable and closable. In the current embodiment the second outlet member 15 comprises a button 15e that is user operable to open and close the tap 15a. The tap 15a comprises a butterfly valve (not shown) that is opened and closed by operation of the button 15e. It will be appreciated that any suitable means of opening and closing may be used, including by a push-pull tap, or a tap with a hinged lid, for example.
In this regard, when the second outlet member 15 is closed, the flowable substance 12 may not pass through the outlet member 15 (in either direction) and when the second outlet member 15 is open, the flowable substance 12 may pass through the outlet member (i.e. from the chamber 11, through the outlet member 15 and out of the container 1, or vice versa).
The second outlet member 15 is configured such that when the second outlet member 15 is closed, air may not pass through the outlet member 15, along the conduit 15c (i.e. from the external surroundings into the chamber 11) and when the second outlet member 15 is open, air may pass, along the conduit 15c, through the outlet member 15 (i.e. from the external surroundings into the chamber 11).
The second outlet member 15 is located above the lower side 7' of the container 1, proximal to the lower side 7' . In this regard, the second outlet member 15 is located at a sufficient height above the lower side 7' to enable it to be securely attached to the front sheet 2. The second outlet member 15 is located substantially mid-way along the length of the lower side 7' (and of the base 4).
The second outlet member 15 is the primary outlet and the first outlet member 13 is the secondary outlet.
If the container 1 is in its upright orientation and the second outlet member 15 is opened, the flowable substance 12 will drain out of the chamber 11, through the second outlet member 15 and out of the container 1.
If the first outlet member 13 is open whilst the flowable substance passes out of the second outlet member 15, the first outlet member 13 will allow air to pass, from the external surroundings, into the chamber 11 as the flowable substance passes out of the second outlet member 15, thereby preventing a vacuum forming in the chamber 11 and thereby allowing for an increase in the rate at which the flowable substance 12 can exit from the second outlet member 15. In this regard, the first outlet member 13 is configured to allow air into the chamber 11, as well as to allow the flowable substance 12 to pass out of the chamber 11.
Similarly, if the container is oriented such that the flowable substance passes out of the first outlet member 13 (e.g. if the container 1 is oriented upside down) and the second outlet member 15 is open, the second outlet member 15 will allow air to pass into the chamber 11 as the flowable substance passes out of the first outlet member 13, thereby preventing a vacuum forming in the chamber 11 and thereby allowing for an increase in the rate at which the flowable substance 12 can exit from the first outlet member 13. In this regard, the second outlet member 15 is configured to allow air into the chamber 11, as well as to allow the flowable substance 12 to pass out of the chamber 11.
The inlet 13i of the first outlet member 13 and the inlet
15i of the second outlet member 15 are offset from each other in the height direction (H- see Figure 2) of the container 1. They are positioned such that when the container 1 is stood upright on its base 4, the inlet 13i of the first outlet member 13 is located higher than the inlet 15i of the second outlet member 15. In this regard, the inlet 15i of the second outlet member 15 is closer to the lower surface 7' of the container (and to the base 4) than the inlet 13i of the first outlet member 13. This facilitates emptying of the chamber 11, as described in more detail below.
The inlet 13i of the first outlet member 13 is offset from the inlet 15i of the second outlet member 15 in a direction that faces away from the exit direction E2 of the second outlet member 15. In this regard, the inlet 13i of the first outlet member 13 is offset from inlet 15i of the second outlet member 15 in a direction opposite to the exit direction E2 of the second outlet member 15. The offset direction may have at least a component in a direction that is opposite to the exit direction E2 of the second outlet member 15.
The first outlet member 13 and the second outlet member 15 are oriented such that their exit directions El, E2 point away from each other. In this regard, the first exit direction El does not have a component in the direction of the second exit direction E2 (and vice versa). This further facilitates emptying of the container 1, as described in more detail below.
Similarly, the outlets 13d, 15d of the outlet members 13, 15 are offset from each other in the height direction. When the container 1 is in its vertically upright orientation, the outlet 13d of the first outlet member 13 is located higher than the outlet 15d of the second outlet member 15.
The container 1 is configured such that it is selfsupporting. In this regard, the container 1 is configured such that it is able to stand up on its base 4 in an upright orientation, on its own. More specifically, the container 1 is configured such that it is self-supporting when the chamber 11 contains the flowable substance 12, preferably when the chamber 11 is filled by the flowable substance 12.
It will be appreciated that references to standing the container 1 upright on its own refer to doing this stably (i.e. permanently) when solely under the influence of gravity and without any other external forces applied to the container 1.
In this regard, the front and rear sheets 2, 3 and the base 4 are made of a material that, although flexible (flexible enough to allow the container to be folded when empty), is rigid enough to allow the container 1 to be self-supporting.
Furthermore, the height, width and depth of the container are such as to allow the container 1 to be self-supporting. In this regard, the base 4 has a size and shape that is sufficient, for example relative to the height of the container, to allow the container 1 to be self-supporting.
Because the container 1 is self-supporting, it does not need an additional external supporting structure, such as a box, to allow the container 1 to be self-supporting.
In this regard, the container 1 does not comprise an outer structure (i.e. located outwardly of the front and rear sheets 2, 3 and the base 4) arranged to support the sheets 2, 3 and base 4. In this regard, the container 1 does not comprise a box that houses the sheets 2, 3 and base 4.
The rigidity of the material of the front and rear sheets 2, 3 may also facilitate, or allow, the mounting of the first outlet member 13 in the opening 14 between the front and rear sheets 2, 3. Also, this rigidity may prevent, or reduce, folds in the sheets 2, 3, which may prevent the flowable substance 12 from being retained in folds at the interface 20. Therefore, this rigidity of material may facilitate the emptying of the container 1 in multiple ways.
The container 1 also comprises a handle 17 (see Figure 1). The handle 17 is located at the top of the container 1. The handle 17 is configured to allow a person to grip and carry the container 1 by the handle 17. The handle 17 has a plurality of apertures 17a for receiving a person's fingers and/or thumbs.
The provision of both the first and second outlet members 13, 15 is advantageous in that it may facilitate emptying of the chamber 11. In this regard, it may allow for some, or all, of any flowable substance 12 that is unable to pass out of the chamber 11 through one of the outlet members 13, 15 to pass out of the chamber 11 through the other outlet member 15, 13.
In this regard, when the container is positioned 1 in its upright position (see Figure 2), and the second outlet member 15 is opened, most of the flowable substance 12 passes out of the chamber 11 through the second outlet member 15 under gravity. However, because it is necessary to mount the second outlet member 15 above the bottom of the container 1, for structural and attachment purposes, not all of the flowable substance 12 is able to pass out of the second outlet member 15. The flowable substance 12 that is below the level of the inlet 15i of the second outlet member 15 does not pass out of the chamber 11 through the second outlet member 15.
The provision of the first outlet member 13, having an inlet 13i that is higher the inlet 15i of the second outlet member 15 (when the container 1 is in the upright position), may allow for the orientation of the container 1 to be changed (e.g. the container may be turned upside down) so that the remaining flowable substance 12 passes out of the chamber 11 through the first outlet member 13. This is also facilitated by having the first outlet member 13 and second outlet member 15 oriented such that their exit directions El, E2 do not point towards each other .
Furthermore because the first outlet member 13 is mounted in an opening 14 between the front and rear sheets 2, 3, this may further facilitate the emptying of the chamber 11. In this regard, it may prevent, or reduce, the flowable substance 12 from being retained at the interface 20 between the front and rear sheets 2, 3, for example at or near where the front and rear sheets are attached to each other (e.g. in folds in the first or second sheets at the interface).
There is therefore a synergy between providing the first outlet member 13 mounted in the opening 14 between the front and rear sheets 2, 3, and providing the second outlet member 15 mounted in an opening 16 of the container 1, since these features may combine to facilitate the emptying of the chamber 11.
Also, the first outlet member 13 may allow for the emptying of the container 1 to be performed in a relatively controlled manner (compared to if there was no first outlet member mounted in the opening). The first outlet member 13 may also allow for a relatively fast emptying of the container 1.
Furthermore, as stated above, if the first outlet member 13 is open whilst the flowable substance passes out of the second outlet member 15, the first outlet member 13 will allow air to pass into the chamber 11 as the flowable substance passes out of the second outlet member 15, thereby preventing a vacuum forming in the chamber 11 and thereby allowing for an increase in the rate at which the flowable substance 12 can exit from the second outlet member 15 (and vice-versa).
A method of passing the flowable substance 12 out of the container 1, according to a further embodiment of the invention, will now be described. Referring to Figures 7a and 7b, the method comprises orienting the container 1 in its vertically upright orientation, preferably by standing it on its base 4, and having the second outlet member 15 in its open configuration when the container is in this orientation (see Figure 7a). The flowable substance 12 (a portion of it) passes out of the second outlet member 15 under gravity (shown by arrow F). It will be appreciated that the container 1 may be oriented in any suitable orientation that allows the flowable substance 12 to pass out of the second outlet member 15 under gravity.
However, the flowable substance 12 below the level of the inlet 15i of the second outlet member 15 is unable to pass out of the second outlet member 15 under gravity.
The method further comprises changing the orientation of the container 1 such that substantially all of the flowable substance 12 that remains in the chamber 11 (or at least a portion of it) passes out of the container 1 through the first outlet member 13 (see Figure 7b) (it will be appreciated that the first outlet member 13 is open in order to allow this). For example the container 1 may be turned upside down, or towards the side of the container 1 on which the first outlet member 13 is mounted (or any other suitable orientation), such that flowable substance 12 that remains in the chamber 11 passes out of the container through the first outlet member 13 (see Figure 7b) .
Alternatively, the container 1 may first be oriented such that the flowable substance 12 pours out of the first outlet member 13 and the orientation of the container then changed so that substantially all (or at least a portion of) the flowable substance that still remains in the chamber 11 (e.g. below the inlet 13i of the first outlet member 13, in that orientation) passes out of the second outlet member 15.
In either case, the first outlet member 13 is open whilst the flowable substance passes out of the second outlet member 15, such that air passes through the first outlet member 13 (from the external surroundings of the container 1) into the chamber 11. This may prevent a vacuum forming in the chamber 11, as the flowable substance 12 passes out of the second outlet member 15, thereby allowing for an increase in the rate at which the flowable substance 12 exits from the second outlet member 15. Alternatively, the first outlet member 13 may be closed whilst the flowable substance passes out of the second outlet member 15.
Similarly, the second outlet member 15 is open whilst the flowable substance passes out of the first outlet member 13, such that air passes through the second outlet member 15 (from the external surroundings of the container 1) into the chamber 11. This may prevent a vacuum forming in the chamber 11, as the flowable substance 12 passes out of the first outlet member 13, thereby allowing for an increase in the rate at which the flowable substance 12 exits from the first outlet member 13. Alternatively, the second outlet member 15 may be closed whilst the flowable substance passes out of the first outlet member 13.
A method of passing the flowable substance 12 into the container 1, according to a further embodiment of the invention, will now be described. Referring to Figure 8, the method comprises passing a flowable substance 12 into the chamber 11 through the first outlet member 13 (see arrow F) . The second outlet member 15 is closed whilst the chamber 11 is filled through the first outlet member 13, to allow the chamber 11 to fill up with the flowable substance 12. Once the chamber 11 is full (or at least partially full), the first outlet member 13 is closed. Alternatively, or additionally, the container 1 may be filled through the second outlet member 15 (whilst the first outlet member 13 is closed) . It will be appreciated that the first and second outlet members are configured to allow a flowable substance to also flow from the exterior of the container 1, through the outlet member, into the chamber 11 (i.e. they allow the flowable substance to flow in both directions).
A method of passing the flowable substance 12 out of the container 1, according to a further embodiment of the invention, will now be described. Referring to Figure 9, the method comprises orienting the container 1 in its vertically upright orientation, by mounting it on its base 4 (or by holding the container in mid-air, in this orientation). The second outlet member 15 is then opened (or is opened prior to the container being oriented in this way) and the flowable substance 12 (a portion of it) passes out of the second outlet member 15 under gravity (see arrow F).
Whilst the flowable substance 12 passes out of the second outlet member 15, the first outlet member 13 is open such that air passes through the first outlet member 13 (from the external surroundings of the container 1) into the chamber 11 (see arrow A). This may prevent a vacuum forming in the chamber 11, as the flowable substance 12 passes out of the second outlet member 15, thereby allowing for an increase in the rate at which the flowable substance 12 exits from the second outlet member 15.
Alternatively, the container 1 may be oriented such that the flowable substance 11 passes out of the first outlet member under gravity, with the second outlet member 15 open whilst the flowable substance passes out of the first outlet member 13, such that air passes through the second outlet member 15 (from the external surroundings of the container 1) into the chamber
11. This may prevent a vacuum forming in the chamber 11, as the flowable substance 12 passes out of the first outlet member 13, thereby allowing for an increase in the rate at which the flowable substance 12 exits from the first outlet member 13.
A method of manufacture 1000 of the container 1, according to a further embodiment of the invention, will now be described. Referring to Figure 10, the method comprises attaching the front and rear flexible sheets 2, 3 to each other to define a chamber 11 therebetween for storing a flowable substance 12 (step 1001); mounting the first outlet member 13 in an opening 14 between the front and rear sheets 2, 3 (step 1002), and mounting the second outlet member 15 in the opening 16 of the container 1 (step 1003) .
The first outlet member 13 may be mounted in the opening 14 between the front and rear sheets 2, 3 before or after the second outlet member 15 is mounted in the opening 16.
The first outlet member 13 may be mounted in the opening 14 between the front and rear sheets 2, 3 before or after the front and rear sheets 2, 3 are attached to each other.
It will be appreciated that numerous modifications to the above described design may be made without departing from the scope of the invention as defined in the appended claims.
For example, in the described embodiment the first and second outlet members 13, 15 comprise a spout 13a and tap 15a respectively. It will be appreciated that any suitable type of outlet member may be used for the first and second outlet members, including any form of pourer or pouring member for example .
The positions of the first and second outlet members 13, 15 may be varied, but preferably such that their inlets 13i, 15i are offset from each other, and more preferably such that they are spaced from each other in the height direction (i.e. the height direction when the container 1 is stood up vertically upright on its base 14) .
The orientations of the exit directions El, E2 of the spout 13 and tap 15 may be varied, but preferably such that exit directions El, E2 do not point towards each other, and more preferably such that the exit directions El, E2 point away from each other.
Where in the foregoing description, integers or elements are mentioned which have known, obvious or foreseeable equivalents, then such equivalents are herein incorporated as if individually set forth. Reference should be made to the claims for determining the true scope of the present invention, which should be construed so as to encompass any such equivalents. It will also be appreciated by the reader that integers or features of the invention that are described as preferable, advantageous, convenient or the like are optional and do not limit the scope of the independent claims.
