Abstract

A kit of parts for a feeder [1] has a body [2] and a bung [8] which can slide within the body [2]. A periphery of the bung [8] can form a sliding seal between that periphery and the internal side walls of the tubular body [2]. A base cap [11] has an aperture [12] through it and is mountable at a lower end [4] of the body [2] to substantially occlude that end [4] and to allow airflow through the aperture [12] into the body [2] as the bung [8] moves away from the lower end [4] of the body [2]. The kit of parts has a teat mouthpiece [9] for liquid foods, a sipper mouthpiece [41] for pureed food and a spout mouthpiece [51] for mashed food and a pump attachment [61]. The pump attachment [61] has a pump and a spoon [63]. The pump has a pump bung [72] which moves reciprocatingly within the body [2] and which forms a sliding seal with the internal side walls of the body [2]. A valve [77] allows food to flow from the feeder [1] but prevents the flow of food into the feeder [1]. A feeder [1] is also disclosed.

[0001] This application claims priority to Australian Provisional Patent Application No. 2013904071 in the name of JAG Mayer Ply Ltd, which was filed on 22 October 2013, entitled "A Dispenser" and to Australian Innovation Patent No. 2013101385 in the name of JAG Mayer Ply Ltd, which was filed, on 22 October 2013, entitled "A Dispenser' and the specifications thereof are incorporated herein by reference in their entirety and for ail 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 tha they can give to toddlers so thai 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 offere 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 contents out of these containers is both frustrating and wasteful. Also toddlers are able to create a mess when given these containers by excessivel 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.

Description of preferred embodiments of the invention
[0041] The embodiments of the feeder 1 that are illustrated in figures 1 A to 1G comprise: a base cap 1 1 , a valve carrier 14, a movable bung 8, a tube 2, a teat mouthpiece 9 and an upper collar 1 .
[0042] Although the tube 2 of figures 1 A to I F 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 upper and lower open ends 3 and 4 and earri.es screw threads 6 and 7 adjacent those upper and lower ends. Although the screw threads 6 and 7 of figures 1 A to 10 are external to the tube 2, those screw threads may be internal to the tube 2. An over-moulding 5 encases a substantial portion of the exterior surface of the tube 2 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 whic are mounted on that screw thread.
[0043] The tube 2 of figures 1A 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 1 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 ease where the tube 2 is marked with 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 blade 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 extends radially from the- bung 8. The tolerances between the movable bung 8 and the inner surface of the t ube 2 are such as to form a sliding seal between the movable bung 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 of the tube .2 and is resting hard up against the underside of the mouthpiece 9, The blades 23, 24 and 26 around the movable bung S scrape along the inside wall of the tube 2 as the movable bung 8 moves up towards the mouthpiece 9, leaving virtually none of the contents behind.
[0045] A base cap 1 is mounted at the lower open end 4 of the tube 2 and prevents the movement of the bung 8 out of that end. For this purpose the base cap 1 1 carries an iniernal screw thread .18 which matches the external screw thread 7 of the tube 2. The base cap 1 1 is pierced by a an air hole 12.
[0046] The base cap 11 also retains a valve carrier 14 in place over the lower open end 4 of the tube 2. The valve carrier 14 has a peripheral region 15, a valve 16 and a pull-tab 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 is illustrated in the drawings) comprises a dome portion the periphery of which is contiguous with a cylindrical portion. A sphere valve is not illustrated 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 thai 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 the base cap 1 1 . 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 1 , keeping the bung 8 in place by not allowing it to fall downward. The pull-tab 0 enables easy removal of the valve carrier 14, such as for cleaning. As is shown if figure IH, the base cap 1 1 comprises an outer peripheral skirt 25 which surrounds the periphery 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 a internal screw thread 21 which matches the external screw thread 6 of 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 whic 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 1C, I D and IE, it is preferred to provide a cap 31 which can be 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 bold an upper 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 ca 31 is detachably held in place by being an interference fit over the upper collar 19, As is illustrated in figure IE, the cap 31 can be stored adjacent the lower end 4 of the tube 2 by retention between the outer skirt 25 and the centra! body 30 of the base cap 1.1. 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 12 into the tube 2,
[0050] As is illustrated in figures 2A to 2C, it is preferred to provide a funnel 34 to aid in the loading of material into the feeder 1 , The funnel 34 has a handle 36 which 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 the invention that are illustrated in figures 3A to 3G differ from the embodiments of figures 1A to I G in that the teat mouthpiece 9 has been replaced by a sipper mouthpiece 41. The sipper mouthpiece 41 is hollow and. comprises a base 42 from which extends a sipper body 43 which is preferably substantially elliptical in cross - section and which terminates in a blun end 44. The blunt end 44 is pierced by a slit 46 which extends across an. axis of that end and operates in the same manner as do teats for baby feeding bottles.
[0052] The embodiments of the invention that are illustrated in fi gures 4A to 4G differ from the embodiments of figures 1 A. to I G in that the teat mouthpiece 9 has been replaced by a spout mouthpiece 51. The spout mouthpiece 51 comprises an open-ended spout 53 which extends upwardly from a base 52, A valve 54 in the base 52 allows for one-way flow of material from the tube 2 into the spout 53. The purpose the valve 54 is to prevent contents of the feeder 1 from spilling out when the feeder is on its side or upside down. This valve is designed to be weaker than the one-way air valve 16 located in the movable bung 8, to enable the contents of the feeder 1 to dispense smoothly.
[0053] The embodiments of the invention that are illustrated in figures 5A to 5G differ from the embodiments of figures IA to I G in that the teat mouthpiece 9 has been replaced by a spoon pump attachment 1. [0054] The spoosi pump attachment 61 allows parents to feed their infants single- handedly, whilst also promoting utensil education for the infant.
[0055] The spoon pump attachment 61 comprises a spoon 63 and a pump. The pumps dimensioned to dispense just enough contents to fill the spoon 63. The spoon 63 comprises a spoon head 68 and a spoon rube 64 so that the spoon head 68 is in communication with the hollow interior of the spoon tube 64. A spoon trigger 67 projects substantially radially from the spoon tube 64, The pump comprises the top cap pump pack 68, the helical spring 71, the pump bung 72 and the pump one way valve 77. The structure and function of the various components of the of the spoon pump attachment are as follows
Spoon top cap 62
[0056] A spoon top cap 62 snap fits onto the feeder 1, protecting the spoon 63 when it is not in use, it can also be clipped into the base cap 1 1 during use.
Spoon 63
[0057] The spoon 63 clips onto the top cap pump pack 68, It has a tube 64 that fits into the pump bung 72 and opens onto the spoon head 66. The contents of the feeder 1 will travel through the tube 64 onto the spoon head 66. Underneath the tube 64 at the back of the spoon head 66 is the spoon trigger 67 where the user applies pressure to engage the pump mechanism.
To cap pu mp pack 68
[0058] A top cap pump pack 68 is fitted to the pump bung 72 with a quick release bayonet fitting. The bayonet fitting comprises the bayonet slots 74 in the pump bung tube 73 and corresponding projections 60 within the top cap pump pack 68. Together with the spring stop 69 it houses the spring 71 , The top of the pump bung 72 and the tube 64 of the spoon run through the middle of the top cap pump pack 68, spring 71 and spring stop 69.
Spring 71 [0059] The coil spring 71. s fitted to the spring stop 69 and housed in the top cap pump pack 68. Its purpose is to return the spoon 63, top cap pump pack 68 and pump hung 72 back to its original position, Spring Stop 69
[0060] The spring stop 69 is fastened to the feeder tube 2 by the pump collar 68. Its purpose is to house the spring 71 and attach the pump mechanism to the tube 2.
Pump Collar 78
[0061] The threaded pump collar 78 fastens the spoon pump attachment 61 to the lube 2. It has an extended collar that reaches above the top cap pump pack 68 to the base of the spoon attachment 61. in. order to protect the user from pinching skin when pumping the spoon attachment 61. Pump B ig 11
[0062] The top of the pump bung 72 is a tube 73 that attaches to the top cap pump pack 68. The tube 64 of the spoon fits into the tube 73 at the top of the pump bung 72. The pump one-wa valve 77 clips into the base of the pump bung tube 73. The pump bung 72 comprises a body 75 which receives a radially-extending circumferential seal 76. The outer periphery of the seal 76 forms a sliding seal with the internal wall of the tube 2. A radially-extending location/alignment ring 79 is integrally formed with the body 75 below the circumferential seal 76 and a radially extending scraper/seal blade 80 is integrally formed with the body 75 below the location/alignment, ring 79. The circumferential seal 76, the location/alignment ring 79 and the scraper/seal blade 80 result in the pump bung 72 fitting tightly within, and sealing with, the tube 2.
[0063] When downward pressure is applied to the spoon trigger 67, the pump bung 72 will move downward inside the feeder tube 2. The contents will be force to squeeze through the pump one way-valve 77 out through the spoon tube 64 onto the spoon head 66. Pump One-way Valve 77
[0064] The pump one way valve 77 clips into the base of the pump bang tube 73. The pump one way valve 77 allows the contents of the feeder 2 to squeeze out onto the spoon 63, hut will not allow the contents to be sucked back into the tube 2. The pump one way valve 77 is designed to be weaker than the one way valve 16 which is fitted at the bottom of the feeder. This will allow a smoother feed of the contents dispensing, rather than a squirt,
[0065] The embodiments of the invention that are illustrated in figures 7A to 7D differ from the embodiments of figures I A to 1 G in that the teat mouthpiece 9 has been replaced by a storage cap 81. The storage cap 81 fits onto the top of the tube 2 and is held in place by the upper collar 19. The storage cap 81 is intended for use on. the tops of spare feeders and for the storage of feeders during travel or in refrigerators or in coolers.
[0066] The different mouthpieces are designed to accommodate different textures of materials. The teat mouthpiece 9 accommodates liquids, such as milk, water and juices. The sipper mouthpiece 41 accommodates purees, such as pureed vegetables, fruits, cereals, smoothies and yoghurt. The spout mouthpiece 51 accommodates mashes, such as mashed vegetables, fruits, proteins, and chunky soups,
[0067] The spoon pump attachment is designed to allow parents to feed their infants single-handedly, while also promoting utensil education for the infant. The spring-loaded pump is regulated to dispense just enough contents to f ll the attached spoon.
[0068] The presently-described embodiments of the invention are manufactured in any suitable material by any suitable process, but particularly preferred materials and processes for various components are set out in the following table.
