Detailed Description of the Drawings [0030] Referring to figure 1, a personal liquid supply system 100 includes an armband 10 and a drink pouch 40. The drink pouch 40 is carried in a pocket 12 of the armband 10. The drink pouch 40 could also be integral with the armband 10. However, in one application, it is envisaged that one armband 10 could be provided with multiple drink pouches 40, each for multiple use and subsequent disposal after a period of time.

[0031 ] Referring to figure 2, the drink pouch 40 includes a flexible bag 42 and a nozzle 44.

The bag 42 is generally flat when not charged or filled with liquid. Thus, the bag 42 can conform to a wearer’s arm at least to some degree. The nozzle 44 includes a spout 60, a valve 70 and a mouthpiece 80. The nozzle 44 and its components are described in detail with reference to figures 8 to 14.

[0032] The bag 42 includes a first flexible sheet or panel 46 and a second flexible sheet or panel 48. The panels 46, 48 are joined together along their peripheral edges to form the bag 42. The bag 42 defines an expansible space or reservoir between the panels 46, 48 for holding a liquid. The sheets 46, 48 may be of any suitable flexible material for holding a liquid, such as a paper, plastic and/or foil materials, in single or multiple layers. The sheets 46, 48 are liquid impermeable. The sheets 46, 48 are integrally connected along a fold line 52 at one lateral edge 55 and thermally bonded or welded together along an edge portion 51 of the other lateral edge 56 to form a seam 50 of the bag 42.

[0033] The bag 42 has a bottom 53, a top 54, a lateral edge 55, and a lateral edge 56 where the seam 50 extends from the bottom 53 to the top 54. The top 54 of the bag 42 is narrower than 2016102131 18 Dec 2016 5 the bottom 53 of the bag 42. The lateral edge 56 includes an upright portion 56.1 extending perpendicularly from the bottom 53 and a slanted portion 56.2 extending from the upright portion 56.1 to the top 54.

[0034] The top 54 of the bag 42 has an aperture, opening or mouth 43 for charging the bag with liquid. The mouth 43 at the top 54 of the bag 42 can be opened for charging the bag 42 with liquid and then sealed again. The panels 46, 48 are joined together at the top 54 of the bag 42 in a releasable manner to form the mouth 43. The bag 42 includes a zipper mechanism 90 extending along the top of the bag 42 for joining the upper edge portions of the panels 46, 48 together to seal closed the mouth 43 in a releasable manner.

[0035] The zipper mechanism 90 has one or two zippers 92 extending between the lateral edges 55, 56 at the upper region of the bag 42. For example, the zipper mechanism 90 has two spaced parallel zippers 92. Each zipper 92 has a male press-seal strip on the inside surface of one panel 46, 48 which is opposite a corresponding female press-seal strip on the inside of the other panel 46, 48. Thus, the zippers 92 can be in the form of zip lock mechanisms. The male and female press-seal strips interlock when pressed together to seal the top 54 of the bag 42. The press seal strips can be disengaged from each other by pulling apart the free ends of the panels 46, 48 at the top of the bag to open the mouth 43 of the bag 42. As is known, zip lock mechanisms can be provided in various forms depending on the application. For example, the zippers 92 are zip lock mechanisms that are selected to be sufficiently robust so as not to open when the bag 42 is filled and is being shaken during vigorous exercise such as running. The zippers 92 can be configured to be opened and closed by pulling and pressing, respectively. Alternatively, where one zipper 92 is provided, the zipper mechanism 90 can have a slider to open and close the zipper 92.

[0036] Referring to figures 3 to 6, the armband 10 includes a base panel 14 and a pocket panel 16. The base panel 14 wraps around a person’s upper arm, in use.

[0037] The base panel 14 includes a mid-section 18 and two straps 20, 22 extending from opposite sides of the mid-section 18. The strap 20 is shorter and broader than the strap 22. The strap 20 includes two spaced parallel slits 24. The strap 22 is longer and narrower than the strap 20. The strap 22 includes a strip 26 of loops of a hook-and-loop fastener and a tab 28 of hooks of the hook-and-loop fastener. The base panel 14 is preferably of flexible neoprene or other suitable plastics material. Other fastening systems such as quick-release clips that are adjustably engaged with the straps 20, 22 could be suitable. The inventor envisages that the armband 10 can be provided in any number of lengths to suit users of various ages and sizes. 2016102131 18 Dec 2016 6 [0038] The pocket panel 16 overlays the mid-section 18 and is fixed to the base panel 14 along part of its periphery to form the pocket 12. The pocket 12 defines a space between the base panel 14 and the pocket panel 16 for holding the bag 42. The pocket panel 16 may be a stretch mesh fabric cover 16.1 bordered by edge piping 16.2.

[0039] The mid-section 18 and the pocket panel 16 have the same outer profile. The pocket panel 16 is stitched or welded to the mid-section 18 along main and upper stitch lines 30, 32 shown in figure 6. The main stitch line 30 is generally U-shaped and extends along the sides and the base of the mid-section 18. The upper stitch line 32 extends along the upper edge of the mid-section 18. There are gaps 34 between the main stitch line 30 and the upper stitch line 32. The gaps 34 provide openings 36 in the pocket 12. The nozzle 44 can project through either opening 36 so that the armband 10 is suited for left or right arm use. The gaps 34 correspond with the slanted portion 56.2 of the lateral edge 56 of the bag. The slanted portion 56.2 of the bag 42 lies adjacent one of the gaps 34 in the stitching when received in the pocket 12.

[0040] The pocket panel 16 is generally square or rectangular with scalloped cut-outs or indents 16.3, which correspond with the openings 36 in the pocket 12.

[0041 ] The mid-section 18 of the base panel 14 has a slot 38 through which the drink pouch 40 can be fed into the pocket 12. The mid-section 18 of the base panel 14 further includes drainage holes 39 at a lower end region of the mid-section. Any liquid spilled into the pocket 12 can drain from these drainage holes 39.

[0042] The armband 10 is worn by a person as shown in figure 7. The strap 22 partially wraps around the person’s upper arm 96 and extends to one of the slits 24 through which a free end 23 of the strap 22 is threaded. The strap 22 is pulled through the slit 24 to tighten the armband 10 around the arm 96 for a secure and comfortable fit. The armband 10 is secured in place by folding the section of the strap 22 extending from the slit 24 to the free end 23 back onto the strip 26 so that the tab 28 adheres to the strip 26. The armband 10 can be loosened or tightened by adjusting the length of the section of strap 22 which is pulled through the slit 24. For arms of larger diameter, the strap 22 is passed through the slit 24 closer to the free end of the strap 20. For arms of smaller diameter, the strap 22 is passed through the slit 24 closer to the mid-section 18. It is envisaged that any number of slits can be provided for adjustability.

[0043] There is an opening 36 in each lateral side of the pocket 12. The armband 10 may be worn on either the left or the right arm, and the strap 22 wrapped in any direction around the upper arm 96, but at least one of the openings 34 will be facing forward. The drink pouch 10 can thus always be inserted into the pocket 12 with the nozzle 44 forward facing. 7 2016102131 18 Dec 2016 [0044] In use, the person drinks from the drink pouch 40 by lifting his/her arm 96 and bringing his/her mouth to the nozzle 44. It will be appreciated that there are many advantages to this hands-free method of drinking during sport or other activities. The supply system 10 is convenient for sports where the arm swings as the nozzle is 44 is brought close to the person’s mouth during the swinging motion. The user merely needs to tilt his/her head down to the upper arm 96 to be able to suck on the nozzle 44. The hands-free method is also convenient for water sports and activities such as board-riding or surfing.

[0045] Figures 8 and 9 show exploded views of the nozzle 44. The nozzle 44 includes three parts, the spout 60, valve 70 and mouthpiece 80. The spout 60 is fixed in the bag 42 between the panels 46, 48. The valve 70 snap fits to the spout 60 in a rotatable manner. The mouthpiece 80 is secured to an end of the valve 70.

[0046] The spout 60 includes a base 61 and a valve member 62. The base 61 has a partially flattened profile when viewed from an opening of the mouthpiece. For example, the base 61 is oblong shaped to present a partially flattened profile when viewed from an opening of the mouthpiece. The base 61 has opposite sides 63 which are each generally bow-shaped and taper to lateral edges 64 of the base 61. The sides 63 include two spaced channels or grooves 65 which extend between the lateral edges 64 of the base 61.

[0047] The valve member 62 projects from the base 61. The valve member 62 is generally cylindrical. A distal end of the valve member 62 includes a set of circumferentially arranged gripping fingers 66. The gripping fingers 66 extend radially inwardly to define a socket between ends of the fingers 66. The gripping fingers 66 are resiliently deformable.

[0048] Two diametrically opposite inlet openings or windows 67 are defined in the wall of the projecting portion of the valve member 62. The windows 67 are open or in fluid communication with the bore 68 of the valve member 62.

[0049] The spout 60 is fixed in the bag 42 along the slanted portion 56.2 of the lateral edge 56. The sides 63 of the base 61 are welded or glued between edge portions of the panels 46, 48 of the bag 42. The base 61 is captured between the edge portions of the panels 46, 48. The valve member 62 projects into the bag 42 with the inlet windows 67 open to the inside or reservoir of the bag 42.

[0050] Figure 11 illustrates the oblong, tapered shape of the base 61. This helps to provide a continuous and gradual transition of a profile of the edge portions of the base 61 once it is welded or glued between the edge portions of the panels or sheets 46, 48. As a result, the pouch 40 can maintain a generally flat or partially flattened overall condition. This facilitates a comfortable fit and 8 2016102131 18 Dec 2016 helps to stop the armband 10 bumping or getting caught. It also facilitates an aesthetically desirable appearance.

[0051 ] Furthermore, the continuous and gradual transition of the profile facilitates welding or gluing of the sides 63 between the panels 46, 48. The channels or grooves 65 can enhance the welding or gluing by providing enhanced contact surface area and, in the case of glue, enhanced fill area.

[0052] The valve 70 includes a head 71 and a hollow stem 72. The stem 72 is received in the bore 68 of the valve member 62. The stem 72 is rotatable in the bore 68. A neck 73 of the stem 72, at a distal end of the stem 72, is gripped by the fingers 66 of the spout 60. The neck 73 has an annular groove 74 in which ends of the fingers 66 are received. The stem 72 is rotatable in the bore 68, but the gripping fingers 66 in the groove 74 prevent axial displacement of the valve 70 away from the spout 60. The neck 73 has a chamfered distal end to part the gripping fingers as the stem 72 is inserted into the bore 68. As the gripping fingers ride over the end of the neck 73 they snap into the groove 74.

[0053] The stem 72 is hollow having a passage 75 which extends from a base of the neck 73 to an opening 78 at the front of the head 71. The stem 72 includes windows 76 in a wall of the stem 72, which are open or in fluid communication with the passage 75. The windows 76 are axially spaced along the stem 72 so that the windows 76 are at the depth of the windows 67 of the spout 60 when the valve 70 is mounted to the spout 60. The passage 75 is closed off below the windows 76 by a wall 77 so that liquid entering the passage 75 can flow into the opening 78 at the front of the head 71 only.

[0054] The head 71 is generally isosceles-trapezoidal with a truncated tip at the opening 78. A base 79 of the head 71 is oblong so as to correspond with the shape of the base 61 of the spout 60. The head 71 has a number of transverse ribs 97.

[0055] The windows 76 in the stem 72 are aligned with the windows 67 of the spout 60 when the valve 70 is oriented relative to the spout 60 in an open position as shown in figure 10. Twisting the valve 70 through 90 degrees to a closed position rotates the windows 76 completely out of alignment with the widows 67 of the spout 60, cutting off the supply of liquid to the passage 75. Figure 13 shows the open position of the valve 70 and the arrow 98 of figure 14 indicates rotation of the valve 70 to the closed position of the valve 70 as shown in figure 14.

[0056] The mouthpiece 80 fits over the head 71 of the valve 70. The mouthpiece 80 includes a skirt portion 81 and a bite valve 82. The skirt 81 includes internal grooves in which the ribs 97 are received to secure the mouthpiece to the head 71. The bite valve 82 has an inlet 83 and an outlet 2016102131 18 Dec 2016 9 which is a normally closed dispensing slit 84. The head 71 of the valve 70 is received in the skirt portion 81 in an arrangement wherein the opening 78 at the front of the head 71 is open to the inlet 83 of the bite valve 70. Liquid flowing through the passage 75 of the valve 70 flows to the slit 84 of the bite valve 70. The slit 84 is normally closed and opens only when a person performs a biting action on the bite valve 82. The biting action pinches the bite valve 82 to cause the slit 84 to open and allow liquid to flow from the bite valve 80 into the person’s mouth.

[0057] The mouthpiece 80 is injection moulded from a flexible, food grade material such as silicone.

[0058] The remaining material of the spout 80 can be selected to be resiliently flexible, yet rigid enough for operation. This helps to ensure comfortable fit of the armband and can inhibit damage to the bag 42, for example, when the armband is roiled up.

[0059] The drink pouch 40 is carried in the pocket 12 of the armband 10 to allow for hands-free drinking of liquid inside the drink pouch 40. Correct adjustment of the armband 10 positions the bite valve 82 so that simple lifting of the arm 96 presents the bite valve for easy hands-free drinking from the drink pouch 40. The drink pouch 40 can be re-used by opening the bag 42 to fill the bag with liquid.

[0060] The bite valve 82 provides selected dispensing of liquid from the drink pouch 40 when the bite valve 82 is compressed. It is useful to shut off the supply of liquid to the bite valve to prevent unintended dispensing of liquid. The nozzle 40 is configured with the valve 70, which can be selectively and angularly displaced between an open position wherein fluid from inside the drink pouch can flow to the bite valve 82 and a closed position wherein the fluid passage from inside the bag 42 to the bite valve 82 is obstructed.

[0061 ] With many existing supply systems, such as those having a flexible liquid container or bag carried on the person’s back, a user is required to detach a nozzle from a holder of sorts and to bring the nozzle to his or her mouth. This can cause the user to become distracted. Loss of stride or even a fall, for example when trail running, can be a consequence of such distraction.

[0062] Many existing liquid supply systems, such as those worn on the back or on a belt are simply not suitable for water sports, such as swimming, surfing, skiing or board riding. The armband 10 provides forms part of a system that can allow a person to focus on a water sport while still taking liquid. Furthermore, the flattened nature of the armband 10, even when the pouch 12 is charged provides a generally streamlined profile that presents a minimal amount of drag in the water. This would not be possible with many existing liquid supply systems. 2016102131 18 Dec 2016 10 [0063] In other systems, it is common for a container of a semi-rigid plastics material to be worn on a belt. These are often used to store energy or other nutritional supplements, such as those that are diluted and sipped during an endurance event. Many athletes tend to take small frequent sips, rather than large drinks, which can cause nausea and vomiting. As a result, the athlete is constantly taking the container from the belt, sipping and replacing. This can also cause the user to become distracted, lose stride or even fall.

[0064] It is a useful feature of the system 100 that the nozzle 40 is accessible simply by lifting the arm. In combination with a device such as the bite valve 42, a user need not detach a nozzle from a holder and lose concentration.

[0065] It is also a useful feature of the system 100 that the bag 42 is flexible. This allows a tautness of the armband 10 to exert pressure on the contents of the bag 42, so facilitating supply of liquid. In addition, the flexibility of the bag 42 allows the bag 42 to collapse as the liquid is supplied. As a result, splashing of the liquid in the bag 42 is inhibited. This collapsing is further facilitated by the oblong, partially flattened profile of the base 61 of the spout 60. A round base would interfere with collapsing of the bag 42.

[0066] The armband 10 is of a pliable and extensible material such as neoprene or the like, for example, wet suit material. The material can thus be selected to suit wet or damp conditions, such as those encountered during water sports or resulting from sweat.

[0067] The sheets 46, 48 are of a plastics material such as Nylon, Polyethylene or a thermoplastic polymer, such as Polyethylene terephthalate or any number of other similar materials. The material is food grade, where necessary.

[0068] The armband 10 and the pouch 40 are capable of being rolled up and stored in a clothing pocket or the like due to the nature of the materials described above.

[0069] The zipper(s) 92 are selected to be sufficiently resiliently flexible so that, once released, their ends can be urged towards each other, so allowing the mouth 43 to open to an extent that facilitates charging the bag 42. With existing systems in which a spout or lid is unscrewed or undipped, the resultant opening is often not large enough to inhibit or avoid spilling, particularly in adverse conditions. The bag 42, on the other hand, can be opened fully and subsequently resealed in a space-saving manner.

[0070] The bag 42 can be provided with various filled volumes. For example, the bag 42 can have a filled or charged volume of between about 200 ml and 300 ml, such as about 250 ml. 2016102131 18 Dec 2016 11 [0071 ] The inventor envisages that the bag 42 can be used by itself without the armband 10. In that case, the bag 42 could simply be stored in a belt, so some other suitable location, to be used and replaced or discarded, where necessary. The shape and positioning of the nozzle facilitates the storage of multiple bags 42 in an efficient manner. This would not be the case with a generally round nozzle.

[0072] Generally round nozzle are often mounted in an opening of a panel or wall of a container. This is done by having the panel or wall sandwiched between a pair of flanges. As a result, the nozzle can have relatively large footprint or area profile when compared with the opening. This can be problematic when storing a number of containers. It would also be difficult to achieve the convenient orientation and generally flattened configuration as is achieved by the system 100.

[0073] It is to be understood that the terminology employed above is for the purpose of description and should not be regarded as limiting. The described embodiments are intended to be illustrative of the invention, without limiting the scope thereof. The invention is capable of being practised with various modifications and additions as will readily occur to those skilled in the art.

[0074] The use of words that indicate orientation or direction of travel is not to be considered limiting. Thus, words such as “front”, “back”, “rear”, “side”, “up”, down”, “upper”, “lower”, “top”, “bottom”, “forwards”, “backwards”, “towards”, “distal”, “proximal”, “in”, “out” and synonyms, antonyms and derivatives thereof have been selected for convenience only, unless the context indicates otherwise. The inventor envisages that various exemplary embodiments of the claimed subject matter can be supplied in any particular orientation.
