Description

CONTAINER TO RECEIVE AND DISPENSE A MEASURED AMOUNT OF PARTICULATE MATERIAL Cross-References to Related Applications [0001] This application is a National Stage of International Application No. PCT/AU2005/001019, filed July 12, 2005, and which claims the benefit of Australian Patent Application No. 2004903819 filed July 12, 2005, the disclosures of both of which applications are incorporated herein by reference. Field of the Invention [0002] The present invention relates to containers and, in particular, containers to receive and dispense granular or particulate materials. Description of the Prior Art [0003] There are many containers to dispense materials. However, particular problems arise when dispensing granular or particulate materials, such as, sugar, sand, salt, grains, nuts, coffee, 100 and 1000's and washing powder, for example. The main problem with such containers is that it is difficult to dispense a measured amount without the use of a further item such as a measuring spoon or cup. Also, if the container is placed upside down the contents will flow out. [0004] Some containers include nozzles, caps or heads to limit the flow of the container contents. These nozzles, caps and heads become easily blocked under the weight of the material. Typically, containers also require a minimum amount of material to function, won't completely empty and/or have complicated arrangements such as moving parts to dispense the material from the container. [0005] Accordingly, there is a need to provide a dispenser for granular or particulate materials that dispenses a measured amount of material from a container, is simple and affordable and prevents excess material exiting the container even when the container is placed at unsuitable angles. Summary of the Invention [0006 It is an object of the present invention to overcome or ameliorate some of the disadvantages of the prior art, or at least to provide a useful alternative.

2 [0007] There is firstly disclosed herein a container having an interior to receive granular material, said container having: a hollow body including a base and walls normally extending upwardly from the base defining the interior; a passage extending between said interior to an opening by which said granular material is dispensed from said container when the container is rotated clockwise and anti clockwise; and means located along said passage adjacent the base of said container and operable to limit a measured amount of said granular material to be dispensed from said container at one time, said means including: a first passage defined by spaced-apart first and second members providing spaced-apart first and second surfaces extending in an oblique direction from the interior toward the base, the first member and the first surface terminating in an end that is spaced apart from the base, and the second member extending upwardly from the base to an upper end of the second member, a second passage extending in a generally upward direction away from the base to the opening, and a third passage extending about and spaced apart from the end of the first member defining a chamber proximate the base in communication with the first and second passages, wherein a distance in the oblique direction between the end of the first member and the base of the container is selected so that upon the clockwise and anti-clockwise rotation of the container about a generally horizontal axis, granular material in the chamber flows out of the opening and flow of granular material into or out of the chamber and into the first passage and the interior of the container is prevented. [0008] Preferably, the surfaces form a first passage section extending from the interior, a second passage section extending to the opening and a third passage section defining a chamber between the first and second sections. [0009] Preferably, the sections substantially reverse the direction of the passage from the interior to the opening. [0010] Preferably, the offset surfaces are angularly offset.

3 [0011] Preferably, the material in use moves from the interior to the chamber to settle until dispensed, the measured amount being defined by the amount of the material located in the chamber before the material within the first section blocks the first section, the first section unblocking once the material within the chamber is dispensed from the container. [0012] Preferably, when the container is inverted, the material in the first section is inhibited from exiting the container. [0013] Preferably, the interior includes a wall angularly offset to a side of the container. [0014] Preferably, the side of the container is a container base. [0015] Preferably, the container is integrally formed. [0016] Preferably, the passage forms a spiral. [0017] Preferably, the container includes a lid or cap. [0018] Preferably, the lid or cap includes a first aperture to access the opening. [0019] Preferably, the lid or cap includes a second aperture to access the interior.

Description of the Preferred Embodiments [0034] Referring to the drawings there is shown a container 1 having an interior 5 to receive particulate material 7. The particulate material 7 could be, for example, sugar, sand, salt, grains, nuts, coffee, 100 and 1000's, washing powder or other such materials. The container I is generally not for use with a liquid. The container I includes a passage 10 extending between the interior 5 to an opening 15 by which the material 7 is dispensed from the container 1. Means are located along the passage 10 and are operable to limit a measured amount of the material 7 to be dispensed from the container I at one time. The means shown in Figure 1 includes walls or surfaces 15a,b,c,d,e angularly offset from each other to alter a direction of the passage 10 to thereby define the measured amount. A first passage section 20 extends from the interior 5, a second passage section 25 extends from the opening 15 towards the first passage section 20 and a third passage section 30 defines a chamber between the first and second sections 20, 25. Alternate embodiments are shown in Figures 2 to 5, 6a-6c and 7a-7g. In Figure 2, the angularly offset walls or surfaces are shown as items 16a,b,c,d; in Figure 3 as 17a,b,c,d; and in Figures 7 a to g as 18a,b,c,d. [0035] As shown in the drawings, the three passage sections 20, 25, 30 substantially reverse the direction of the passage 10 from the interior 5 to the opening 15. It should be understood that different embodiments of the invention having the passage 10 being formed by more or less angularly offset walls or surfaces are within the scope of the invention. To assist the material 7 in the interior 5 to move into the first passage section 20, the interior 5 can include a wall or barrier 35 angularly offset to a side of the container I and, in particular, the container base 40. The wall 35 may be part of a block 37 as shown in Figures 1 to 3 or may be integrally formed, hollow or any like arrangement.

5 [0036] As best seen in Figures 4 and 5, the container I can include a lid or cap 45 secured to the top of the container I to further assist in dispensing particulate material 7 from the interior 5. The lid or cap 45 can include a first aperture 50 providing access to the opening 15 of the second passage 25. The aperture 50 can include a flip-top portion 55 or the like as shown in Figure 5. The lid or cap 45 could also include a second aperture 60 providing access to the interior 5 for filling the container 1. The second aperture 60 could also include a flip-top portion 57 or the like as also shown in Figure 5. The lid or cap 45 in the preferred form would be an injection molded polypropylene one or two-part piece. The container 1 would preferably be a blow molded HTPE. However, the lid or cap 45 and container I could be manufactured using most typical manufacturing processes and materials. The passage 10 can be of various shapes and sizes, for example a spiral. [0037] In use, and as best seen in Figures 7a to 7g the interior 5 would be filled with a particulate material 7 by way of second aperture 60. The particulate material 7 substantially moves under gravity towards the first passage section 20. The bulk of the particulate material 7 is held in the interior 5. A predetermined amount of particulate material 7 will settle in the chamber 30 as shown in Figure 7a. Due to the friction between the particles 7 and the angular walls or surfaces 17a,b,c,d the first passage 20 will become blocked, preventing further material 7 from settling in the chamber 30. At this stage, the container I has been primed and is ready for use. As shown in Figures 7b,c, and d, a user rotates the container 1 with the particulate material 7 of the chamber 30 moving into the second passage 25 towards and out the opening 15. As the container 1 is further rotated as seen in Figure 7c due to the angular offsets further particulate material 7 from the interior 5 cannot flow into the chamber 30 and only the predetermined amount can proceed down passage 25 and out the opening 15. Referring to Figures 7e to g, once the predetermined amount of particulate material 7 has been dispensed from the container 1, the user reorients the container 1, and the particulate material 7 from the interior 5 reloads the chamber 30 by gravity, drawing the contents to the lowest point. The chamber 30 once filled is ready for the next dispensing action. [0038] Accordingly, the present invention provides a container I having no moving parts which dispenses a measured amount of granular or particulate material 7 until the container I is completely exhausted of material 7 at which time it can be refilled. The container I is simple, efficient and affordable to manufacture and does not require a 6 minimum amount of material 7 to function. Advantageously, only the material 7 in the chamber 30 is allowed to exit with the remainder of the material 7 moving back into the interior 5. It is also conveniently designed to substantially prevent children from spilling the material 7. [0039] Although the invention has been described with reference to specific examples, it will be appreciated by those skilled in the art that the invention may be embodied in many other forms.
