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" and to Australian Innovation Patent No. 2013101385 in the name of JAG Mayer Pty Ltd, which was filed on 22 October 2013 , entitled "A Dispenser"

Field of the invention

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

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.
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.
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 excessively squeezing the food out onto themselves and onto their environment, such as the floor, walls car seats and the like. Known devices are disclosed in WO95/04690A1 , US4010861A and WO2004/002397A1 .
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.

It is preferred that the at least one mouthpiece attachment is one of:

a teat mouthpiece which is adapted to allow the flow of a liquid through it;
a sipper mouthpiece which is adapted to allow the flow of pureed material through it; and
a spout mouthpiece which is adapted to allow the flow of mashed material through it.

It is preferred that the sipper mouthpiece comprises a body which has a blunt end which is pierced by a slit in that blunt end.
It is preferred that the body of the sipper mouthpiece is substantially elliptical in cross-section.
It is preferred that the spout mouthpiece comprises:

a base;
an open-ended spout which extends from the base; and
a valve in the base which allows flow of material into the spout.

It is preferred that the pump comprises:

a pump bung which:
- is adapted for reciprocating movement along the longitudinal axis of the tubular body; and
- has a periphery which is adapted to form a sliding seal between that periphery and the internal side walls of the tubular body;
a valve which is adapted to allow the flow of material from the interior of the tubular body as the pump bung moves into the pump body but to prevent the flow of material into the interior of the tubular body as the pump bung moves out of the pump body; and

Description of preferred embodiments of the invention

The embodiments of the feeder 1 that are illustrated in figures 1A to 1G comprise: a base cap 11, a valve carrier 14, a movable bung 8, a tube 2, a teat mouthpiece 9 and an upper collar 19.
Although the tube 2 of figures 1A to 1F 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 carries screw threads 6 and 7 adjacent those upper and lower ends. Although the screw threads 6 and 7 of figures 1A to 1G 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 which are mounted on that screw thread.
The tube 2 of figures 1A to 1F 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 case where the tube 2 is marked with a scale to indicate the volume of the contents of the feeder 1.
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 tube 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 8 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. More specifically, the upper blade 23 serves as a radially-extending scraping and sealing blade. The intermediate blade 24 serves as a radially-extending locating and alignment ring and the lower blade 26 serves as a radially-extending circumferential seal.
A base cap 11 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 11 carries an internal screw thread 18 which matches the external screw thread 7 of the tube 2. The base cap 11 is pierced by a an air hole 12.
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. Possible forms of the valve 16 include a "dome valve" and a "sphere valve". As is illustrated in the drawings, but not claimed as invention, 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 that the spherical valve is significantly stronger than is the dome valve with regards to back pressure.
The valve 16 is in alignment with the air hole 12 in the base cap 11. 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 it to fall downward. The pull-tab 10 enables easy removal of the valve carrier 14, such as for cleaning. As is shown if figure 1H, the base cap 11 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.
An upper collar 19 has an 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 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.
As is illustrated in figures 1C, 1D and 1E, 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 hold 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 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 be stored 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 11. 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.
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.
The embodiments that are illustrated in figures 3A to 3G differ from the embodiments of figures 1A to 1G 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 blunt 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.
The embodiments that are illustrated in figures 4A to 4G differ from the embodiments of figures 1A to 1G 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.
The embodiments that are illustrated in figures 5A to 5G differ from the embodiments of figures 1A to 1G in that the teat mouthpiece 9 has been replaced by a spoon pump attachment 61.
The spoon pump attachment 61 allows parents to feed their infants single-handedly, whilst also promoting utensil education for the infant.
The spoon pump attachment 61 comprises a spoon 63 and a pump. The pump is dimensioned to dispense just enough contents to fill the spoon 63. The spoon 63 comprises a spoon head 68 and a spoon tube 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

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 11 during use.

Spoon 63

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.

Top cap pump pack 68

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

The coil spring 71 is 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 bung 72 back to its original position.

Spring Stop 69

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

The threaded pump collar 78 fastens the spoon pump attachment 61 to the tube 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 Bung 72

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-way 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.
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

The pump one way valve 77 clips into the base of the pump bung tube 73. The pump one way valve 77 allows the contents of the feeder 2 to squeeze out onto the spoon 63, but 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.
The embodiments that are illustrated in figures 7A to 7D differ from the embodiments of figures 1A to 1G 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.
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.
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 fill the attached spoon.
