The present invention relates to dispensing systems for granular products, and is especially suited for use as a system for storing and dispensing a predetermined quantity of a food product such as a breakfast cereal.
In private homes, ready-to-eat breakfast cereal is generally either stored in the box in which it was purchased or transferred to a sealed receptacle for storage. The consumer then transfers the desired amount of cereal to his serving bowl by pouring or scooping.
Hotels, restaurants, residential institutions and other establishments in which breakfast buffets are available frequently present breakfast cereals in large bowls to which, the consumer may help himself using a scoop. There are many disadvantages associated with these storage and dispensing arrangements.
Firstly, spillage frequently occurs during transfer of the cereal from the storage bowl to the consumer's bowl, causing wastage and mess.
Secondly, freshness is not preserved. If cereal is stored in its original box, air may enter the box and cereal at the bottom of the box may become stale before consumption. In the case of the storage bowl or receptacle, no continual flow of fresh product is maintained, since the bowl or receptacle may be repeatedly refilled from above, resulting in stale cereal remaining at the bottom.
Thirdly, these methods are not hygienic, since the food is exposed to contamination by dust, insect matter and other airborne particles. Such contamination may occur even if the box is closed or a cover is provided, since each consumer must remove the cover prior to helping himself to cereal. Furthermore, the cereal may inadvertently be touched by the consumer during the scooping process.
Fourthly, crushing of the cereal frequently occurs during scooping, resulting in product wastage.
Various solid food devices comprising an enclosed receptacle with an attached dispensing mechanism have been developed to alleviate the problems associated with unsanitary storage and dispensing methods.
However, the majority of conventional dispensers are extremely hard to dissasemble and clean efficiently, since they often contain a multitude of minute components in various three-dimensional planes, which cannot be easily removed or cleaned. This results in a non-hygienic food dispensing system, or requires considerable time and effort to be regularly invested in cleaning the system. For instance, U.S. Pat. No. 2,920,796 to Field describes a dispenser having a multitude of parts. Such systems having a large number of specialized components are expensive to manufacture and difficult to assemble. The need exists for a simple dispensing system which, having a limited number of components, is inexpensive to manufacture and is easy to use and to wash.
Another fundamental disadvantage of conventional systems lies in their failure to provide sealing of the product in the storage section of the dispenser, therefore a food product stored for several days tends to become stale.
Furthermore, most of the known bulk food dispensers cause considerable breakage and crushing of fragile foods such as breakfast cereals. Dispensers which have been described as being suitable for breakfast cereals have a tendency to become jammed. Prior art dispensers are additionally limited since they often do not have a portion control mechanism. In such dispensers, when the dispensing aperture is opened, product will continuously be dispensed, in an unmeasured manner, so that during dispensing the product tends to overflow and spill out of the bowl.
A great need exists for a dispensing system that allows sanitary dispensing of pet food, which is often sold in hefty-sized bags, into which a pet owner often will insert a bowl to remove a portion for use, in a repetitive, and potentially unsanitary manner. The pet food within a large-sized bag is open to the air, so that it will rapidly become stale and air-borne micro-organisms may easily enter. Additionally, when pet food is stored within a large-sized bag, the malodor of the pet food tends to disperse within the room.
It would therefore be desirable to provide a closed, hygienic dispensing system for granular products which does not cause breakage of fragile product, which provides freshness-sealing of the product within a storage area prior to dispensing, and which is simple to use and maintain.
Accordingly, it is an object of the present invention to overcome the disadvantages of the prior art and provide a dispenser which causes minimal breakage of a granular product, in which the components of the system may be quickly and easily disassembled for cleaning and in which the product is sealed in a storage section until required.
In accordance with a preferred embodiment of the present invention there is provided a dispenser for a granular product comprising a receptacle which can be filled with the product and a flexible impeller fixed within the receptacle. The impeller has measuring compartments for measuring and dispensing a predetermined amount of the product. The shape, the dimensions and the flexible material of the impeller ensure that the impeller forms a seal at the dispensing end of the receptacle, maintaining the hygiene and freshness of the granular product. A lid is provided to seal the upper end of the receptacle, so that the product is stored in a substantially air-tight compartment prior to dispensing.
There is thus provided a system for measuring and dispensing predetermined amounts of a granular product, comprising a refillable, sealable receptacle and capable of containing a quantity of a granular product. The receptacle is provided with a neck at its lower end, and the neck terminates in a dispensing aperture. A rotatable and flexible impeller is provided within the neck of the receptacle for measuring and dispensing the predetermined quantity of the product. A handle is present for turning the shaft to rotate the impeller.
A support is included, comprising: a base, and retaining means for removeably receiving the receptacle therein.
The system is capable of easy disassembly for cleaning; the disassembly is performed by removal of the receptacle from the retaining means and by removal of the shaft and impeller from the receptacle.
A feature of the present invention is the provision of a system for maintaining a ready-to-eat granular product under freshness-sealed conditions prior to dispensing of the product without breakage of pieces of the product during storage or dispensing.
A further advantage of the present invention is that the system is easy to fill and maintain.
According to one embodiment, the impeller comprises a hollow central core, with a shaft extending into the hollow core of the impeller into at least one through-hole formed in the side of the neck. The shaft is retained in the horizontal plane, within the neck.
According to another embodiment, the diameter or radial cross-section of the impeller as measured across two generally opposing blades, is similar to, or slightly larger than the diameter or radial cross-section of the neck, providing sealing of said neck.
There is also provided a multi-system for measuring and dispensing a predetermined quantity of a plurality of granular products. The multi-system comprises a plurality of receptacles, each with its associated dispensing impeller and handle as described herein. A single base having a plurality of retaining means for removably receiving the receptacles therein supports the receptacles.
Additional features and advantages of the invention will become apparent from the following drawings and description.
The present invention is herein described, by way of example only, with reference to the accompanying drawings, in which like numerals designate corresponding sections or elements throughout, and in which:
The system of the invention is appropriate for use in dispensing granular products. It is especially suited for dispensing granular food products as these products are regularly dispensed in predetermined amounts, and their freshness must be maintained, while breakage or crushing of the product is best avoided. However, the scope of the invention is not limited for use with food products, and freshness-sealing is often important for storage of other products that can be dispensed using the invention.
Throughout the description, the granular product dispensed is often described as being cereal, however the scope of the invention is not limited to cereal. Many other granular products may be dispensed using the invention, for instance, coffee, soup almonds, nuts, candy, pretzels, confections, snacks, rice and beans are but a few of the many products for which the dispenser of the invention is suited.

Receptacle 12 has a dispensing aperture 50 at the open lower end of the receptacle. A removable lid 18 seals the upper end of the receptacle 12. Lid 18 minimizes contamination by airborne particles and may be easily removed for refilling of receptacle 12 with cereal. Receptacle 12 may optionally be formed of a transparent material, enabling the contents of the receptacle to be viewed by the consumer.
Stand 16 comprises an upper horizontal arm 24, in which receptacle 12 is removably retained, a horizontal base 26 and a vertical portion 28 to maintain a spaced relationship between base 26 and arm 24. A bowl (not shown) may be positioned on base 26 to receive a predetermined quantity of cereal.

According to one embodiment, the impeller 32 comprises a plurality of semicircular flexible blades 38 radiating outwards from a hollow central core 40. Other shapes of impeller blades are possible, such as rectangular or trapezoid, and the impeller blades are not limited to having a semicircular shape. Core 40 is shaped as an elongated cylinder with an inner flat side 43, and is open at each end. A dispensing compartment 39 is formed between each pair of adjacent blades 38. Impeller 32 is formed from a flexible material such as silicone or rubber, having sufficient flexibility to prevent breakage of the cereal pieces.
Referring to the bottom of
The shape and size of the impeller conforms generally to the shape and size of neck 48, providing sealing of the neck 48, and maintaining the hygiene and freshness of the contents of system 10. In the preferred embodiment, this is accomplished since the diameter of the impeller 32 as measured across two generally opposing blades is similar to or slightly larger than the diameter of dispensing aperture 50 of neck 48. In an impeller that does not have semi-circular blades, the radial cross-section of the impeller is similar to or slightly larger than the diameter of dispensing aperture 50 of neck 48. The flexible nature of the impeller blades 38, allows the diameter (or radial cross section) of the impeller 32 to be similar to or slightly larger than that of the neck 48, so that the impeller blades 38 tightly seal the neck 48 to maintain the freshness of the product. The edges of the impeller blades can flexibly conform to fit into the narrow neck, while still allowing sufficient ease of rotation of the impeller for dispensing the product.
Referring to the center of
Flat side 43 of core 40 mates with flat side of shaft 35, and after assembly of system, aids in ensuring that rotation of handle 22 results in propelling of the impeller 32.
Referring now to
Flat side 43 of core 40 is shown in
The optimal size of impeller 32 depends on the average size of the individual food pieces being dispensed. System 10 may be adapted for use in dispensing granular products other than breakfast cereal by increasing or decreasing the angle between adjacent blades 38 in order to regulate the serving portion dispensed. Providing impeller 32 with a larger number of blades 38 will therefore decrease the angle between blades, resulting in smaller serving portions, making the system suitable for dispensing coffee, soup almonds, nuts, candy, pretzels, confections, snacks, rice and beans. For instance, an impeller having 10 to 12 blades is suited for dispensing coffee and rice. Providing the impeller with fewer blades will result in larger serving portions (larger measuring compartments), which would be suitable, for instance in dispensing pet food. The length of the impeller may be altered as well, to similarly alter the serving size, as necessary, without changing the number of blades (an elongated impeller, for instance, will have larger serving compartments).
Referring now to
Following assembly of system 10, lid 18 of receptacle 12 (both shown in
A first serving compartment 39 formed between two adjacent blades 38 is positioned facing upwards to receive cereal from receptacle 12, so that on filling of receptacle 12, cereal passes through the lower end of receptacle 12, into funnel 44, and thereafter into first serving compartment 39. Handle 22 may then be turned to rotate impeller 32, and this rotation causes alignment of an adjacent serving compartment with funnel 44, and subsequent filling of the adjacent serving compartment. Handle 22 is further turned in the same direction until filled compartment 39 becomes aligned with dispensing aperture 50 of funnel 14. Cereal is thereby discharged through the dispensing aperture 50. By positioning a bowl below dispensing aperture 50, cereal will be dispensed into the bowl.
System 10 can be easily disassembled for cleaning. In disassembly, receptacle 12 is removed from retaining arm 24, nut 36 (if present) is unscrewed, handle 22 is pulled outwards, to remove the handle 22 and the shaft 34 from the through-holes 41. The pulling action will remove shaft 34 from within the hollow core 40 of the impeller 32. Impeller 32 will remain unfastened within the receptacle 12, and can then be removed by lifting lid 18 and reaching into the receptacle 12 from above. Each component may be washed using conventional detergents.
Operation and cleaning of the system is simple, due to the small number of working parts present in the system, so that even a child may operate the system, disassemble the system for cleaning and reassemble it for use. All moving parts (impeller, shaft and handle) mate together in a straightforward manner, similar to a child's interlocking building blocks. The manufacturing cost is lowered due to the simplicity of design (small number of parts necessary).
The system of the invention was designed to save space, since the receptacle is narrow and tall, and requires a minimum of counter or tabletop space. This in contrast to many prior art cereal dispensers, where the storage receptacles are often squat and broad, requiring a great deal of counter space.
Referring to
According to one embodiment, the spacing between the lower (dispensing) end of the receptacle, and the base can be adjusted, so that receiving bowls of various dimensions can be placed upon the base. When a particularly large receiving bowl is to be filled, the receptacle can be secured upon the support at a raised position from which dispensing will proceed.

In all embodiments of the present invention, rotation of the handle in either a clockwise or counterclockwise direction will accomplish identical dispensing results, as long as the handle is rotated to a sufficient extent so as to align a filled serving compartment with the dispensing aperture.
Referring to
In the present invention, optionally, the retaining arm receiving the receptacle can be replaced with a retaining chain or with a flexible retaining band.
The present invention thus provides a dispensing system having minimal components, allowing easy disassembly for cleaning and allowing ease of manufacture. The invention provides freshness-sealing of the food product placed within the receptacle, due to the dimensions, shape and flexible nature of the impeller provided. Such freshness-sealing is novel to the present invention, and is of significant importance in food products.
Having described the invention with regard to certain specific embodiments thereof, it is to be understood that the description is not meant as a limitation, since further modifications will now suggest themselves to those skilled in the art, and it is intended to cover such modifications as fall within the scope of the appended claims.
