A DISPENSER Related Applications
[0001] This application claims priority to Australian Provisional Patent Application No. 2013904071 in the name of JAG Mayer Pty Ltd, which was filed on 22 October 2013, entitled "A Dispenser", to Australian Innovation Patent No. 2013101385 in the name of JAG Mayer Pty Ltd, which was filed on 22 October 2013, entitled "A Dispenser" and Australian Patent Application No. 2014339751 in the name of JAG Mayer Pty Ltd, which was filed 22 October 2014, entitled "A Dispenser" and the specifications thereof are incorporated herein by reference in their entirety and for all purposes.
Field of the Invention
[0002] The present invention relates to bottles and like containers which are suitable for use as feeders. It is particularly suitable for the feeding of infants and of people who are suffering from disabilities, such as, persons who are recovering from facial or dental surgery and the incapacitated elderly, however, it should be appreciated that the present invention is not limited to that use, only. For example, embodiments of the present invention are also suitable for use as dispensers of material other than foods.
Background of the Invention
[0003] Common problems at infant feeding time are the mess created, the wasted food and the time spent cleaning up. There is a need for a re-usable feeding dispenser that is non-spill, easy to fill and easy to clean. Parents also need a container that they can give to toddlers so that they can feed themselves independently.
[0004] Single-use packaging for ready to eat baby foods are accordingly a popular choice for today's parents. A trip down the baby/toddler aisle at the supermarket will confirm this by the sheer numbers of brands and the different types of foods being offered in these packages. Yoghurts, smoothies, fruit jellies, porridge, bolognese, creamy chicken and vegetable purees are just a few of the ready-to-eat meals and snacks that are being offered in these single use packages.

[0005] More recently, re-usable squeezable silicone type containers have entered the marketplace giving parents the option of feeding their children homemade meals in transportable feeding dispensers. However the solution provided by these dispensers is in itself flawed. The inability to empty the entire container contents out of these containers is both frustrating and wasteful. Also toddlers are able to create a mess when given these containers by excessively squeezing the food out onto themselves and onto their environment, such as the floor, walls car seats and the like.
[0006] It is an object of the embodiments described herein to overcome or alleviate at least one of the above noted drawbacks of related art systems or to at least provide a useful alternative to related art systems.
Summary of the Invention

Description of preferred embodiments of the invention
[0041] The embodiments of the feeder I that are illustrated in figures 1A to IG comprise: a base cap 11, a valve carrier 1.4, a movable bung 8, a tube 2, a teat mouthpiece 9 and an upper collar 19.
[0042] Although the tube 2 of figures IA toIF is circular in cross-section, it may have any cross-section. so long as that cross-section is substantially constant throughout its entire length. The tube 2 has upperand lower open ends 3 and 4 and carriesscrew threads 6 and 7 adjacent those upper and lower ends. Although the screw threads 6 and 7 of figures IA to 1G are external to thetube 2 those screw threads may be internal to the tube 2. Anover-moulding5encasesasubstanial portion of the exterior surface of the tube between the upper and lower screw threads 6 and 7. The lower end of the upper screw thread 6 terminates in a thread stop 20 to aid in the orientation of components which are mounted on that screw thread.
[0043] The tube 2 of figures IA to IF is symmetrical in the sense that the screw threads 6 and 7 are identical. According to alternative embodiments of the invention which are not illustrated in the drawings, the feeder I is constructed so that it is not symmetrical in this sense so that the user may identify different "top" and "bottom" ends. The identification of different"top" and "bottom"ends of the tube 2 is useful in the case where the tube 2is marked with a scale to indicate the volume of the contents of the feeder 1.
[0044] The moveable bung 8 is moveable longitudinally within the tube 2 and comprises a top 22, an upper Made 23 an intermediate blade 24 and a lower blade 26. Each of the blades 23, 24 and 26 extends around the periphery of the bung 8 and extend radially from the bung 8. 'The tolerances between the movable bung 8 and the inner surface of the tube 2 are such as to form a sliding seal between the movable hung 8 and the tube 2. The movable bung 8 is preferably constructed of a plastics polymer with a rubber over-mould to create a seal and to provide friction with the tube 2. This friction helps to support the movable bung 8 from moving downward. The top 22 of the movable bung 8 is shaped substantially to complement the underside of the teat mouthpiece 9, This helps to reduce the amount of contents left in the tube 2 when the movable bung 9 has reached the top ofthe tube 2 and isresting hard up against the underside of the mouthpiece 9. The blades 23, 24 and 26 around the movable bung 8 scrape along theinside wall of the tube 2 as the movable bung 8 moves up towards themouthpiece 9, leaving virtually none of the contents behind.
[0045] A base cap 11 is mounted at the lower open end 4 of thetube 2 and prevents the movement of the bung 8 out of that end. For this purpose the base cap I I carries an internal screw thread 18 which. matches the extemal screw thread 7 of the tube 2 The base cap 11 is pierced by a an air hole 12.
[0046] The base cap I I also retains a valve carrier 14 in placeover the lower open end 4 of the tube 2. The valve carrier 14has a peripheral region 15, a valve 1.6 and a pull-Ntab 10. Preferred forms of the valve 16 include a "dome valve" and a "sphere valve". As is illustrated in the drawings, a dome valve (such as valve 16 as isillustrated in thedrawings) comprises a dome portion the periphery of which is contiguous with a cylindrical portion. A sphere valve is not ilusirated in the drawings but it comprises a portion which is substantially more than half of a hollow sphere, the periphery of which is contiguous with a cylindrical portion. A dome valve accordingly has a shallower shape compared to the spherical valve. The functional difference between the two valves is that the spherical valve is significantly stronger than is the dome valve with regards to back pressure.
[0047] The valve 16 is in alignment with the air hole 12 in thebase cap I1. It permits the ready flow of air from the exterior of tube 2 into the interior of that tube and substantially prevents the flow of air in the opposite direction, The air is then trapped in the tube 2 by the one-way valve 16, keeping the bung 8 in place by not allowing i- to fall downward. The pull-tab 10 enables easy removal of the valve carrier 14, such as for cleaning. Asis shown iffigure 1.1- the base cap I I comprisesan outer peripheral skirt 25 which surrounds theperiphery of a central body 30. The periphery of the central body 30 is formed into longitudinally-running channels 17,
[0048] An upper collar 19 has an internal screw thread 21. which matches the external screw thread 6of the tube 2, The upper collar 19 retains a teat mouthpiece 9 in place over the upper open end 3 of the tube 2. The teat mouthpiece 9 has a teat 27 which projects outwardly from the mouthpiece base 28 and the peripheral area of the base 28 is gripped between. the tube 2 and the upper collar 19. The teat 27 is pierced or slit in the known manner of teats for baby feeding bottles.
[0049] As is illustrated in figures IC, 1D and IE. it is preferred to provide a cap 31 which can he placed over the teat mouthpiece 9 for protection and to aid in the prevention of spillages. A substantially cylindrical protrusion 32 depends from the inner top surface of the cap.31 to'holdanupper region of the teat 27. The cylindrical protrusion.32 seals off around the teat to reduce the risk of the spillage of material from the teat. The cap 31 is detachably held in place by being an interference fit over the upper collar 19, As is illustrated in figure 1E, the cap 31 can bestored adjacent the lower end 4 of the tube 2 by retention between the outer skirt 25 and the central body 30 of the base cap 1L The channels 17 in the central body 30 allow air to flow from the exterior, around the edge of the cap 31 and through the air hole 12into the tube 2.
[0050] As is illustrated in figures 2A to 2C, it is preferred to provide afunnel 34 to aid in the loading of material into the feeder 1. The funnel 34 has a handle 36which protrudes from the upper periphery of the funneL It is preferred that the stem 37 of the funnel be a close fit within the upper open end 3 of the tube 2
[0051] The embodiments of theinvention that are illustrated in figures 3A to 30 differ from the embodimets of figures 1A to 1IG in that the teat mouthpiece 9 has been replaced by a sipper mouthpiece 41.
