Description
2:~000~6 DEVICE ~OR DISPENSING A PR~D~TERMINED
AMOUNT OF SOLIDS
The present invention relates to a dispensing device 5 and more specifically to a dispensing device for dispensing a predetermined amount of solid materials in powder or granular form.
Dispensing devices positioned beneath hoppers, containers and the like are well known. In some cases these devices dispense solid materials in the form of powder or granular materials by pushing or pulling a lever such that a measured quantity of the material is dispen~ed. Examples of such dispensing devices are disclosed by ~ammer in U.S. Patent No. 2,561,696 and 15 Jone~ in U.S. Patent 559,386. ~oth of these patents disclose a dispensing aperture or chamber which is positioned first under an opening from a container, hopper or the like 90 material fills the chamber. The chamber is then moved oYer a discharge opening so that the material is dispensed.
Castro in U.S. Patent 4,109,835 shows another embodiment of a dispensing device wherein a dispensing aperture or chamber is fixedly positioned with a top or filling aperture in a top sliding plate and a bottom or discharge aperture in a bottom sliding plate. The plates are moved together from a first position to a second position, in the first position the chamber fills and in the second position the chamber empties. The patents described herein are but a few o~ the known types of dispensers. Furthermore liquid dispensers for soap and the like having similar types of mechanisms are known.
o~
It is an aim of the present invention to provide a portable dispensing device that can be used for dispensing food such as coffee, sugar, salt and the like and which can be hand held over for example a cup of coffee. By squeezing or depressing a handle or dispensing knob, a predetermined measure of sugar can be dispensed into the coffee. The device can preferably be used with one hand. Such a device avoids having to use a spoon to measure a specific quantity of sugar. In 10 existing types of sugar jars it is difficult to control ~-the exact quantity of sugar dispensed and the present measuring device provides a dispenser which always dispenses the same quantity of sugar or othex particulate material every time the handle or knob is depressed.
The present invention provides a device or dispensing a predetermined amount of i~olids comprising a container, a body member below the container having a longitudinal pas~age therein, a top opening from the container to the longitudinal passage, a sliding member with a substantially rectangular cross-section, the sliding member having a sliding fit within the - longitudinal passa~e movable from a first position to a second position, a dispenser aperture extending through the sliding member and positioned under the top opening from the container when the sliding member is in the first position, a bottom openin~ in the body member from a bottom surface of the longitudinal pasisage to permit solids to dispense from the body mem~er when the sliding member is in the second position, the bottom opening not overlapping the top opening.
In another embodiment there is provided an adjustment mechanism for varying the volume of the dispenser aperture so that the amount of solids being dispensed can be varied.

~100046 In drawings which illustrate embodiments of the present invention, Figure 1 is an elevational cross-sectional view showing one embodiment of a dispenser according to the present invention with the dispenser aperture in the fill ` position, Figure 2 is an elevational cross-sectional view o~
the dispenser shown in Figure 1 with the dispenser aperture in the dispense position, Figure 3 is an isometric exploded view of the dispenser shown in Figures 1 and 2, Figure 4 is an isometric exploded view showing another embodiment of a dispenser according to the present invention having a di~penser aperture of which the volume may be varied.
The dispenser 10 shown in Figures 1 to 3 has a clear plastic container 12 with slightly tapered sides and a side indent 14 for insertion of a squeeze handle 16. A
lid 18 is provided at the top of the container 12. At the base of the container 12 a sloped bottom surface 20 extends to a top opening 22 which is positioned adjacent the indent 14. Beneath the container 12 is a body member 22 having transverse to the container 12 a longitudinal i passage 24 in which slide~ a sliding member 26. The !25 sliding member 26 has a slicling fit within the pa~sage 24 and a dispenser aperture 28 extends vertically thro~gh the sliding member 26 having substantially the same cross-sectional area as the top opening 20 in the base of the container 12. The dispenser aperture 28 i8 positioned directly under the top openin~ 20 in the container 12 when the sliding member 26 i~ in the first position or fill position. A steel spring 30 is ~10~)0~6 positioned in the passageway 24 at a closed end pushing against the sliding member 26. A retaining screw 32 is provided extending up from a bottom platle 34 of the body member 22 and acts as a stop to retain the sliding member 24 in the first position or fill positiom, with the top opening 20 aligned with the dispenser apler-ture 28.
The squeeze handle 16 fits into the indent 14 and has a pivot point 36 at the top and two ,engagement protrusions 38 which engage in slots 40 in the top o~ the sliding member 26. When the squeeze handle 16 is squeezed, the sliding member 26 moves in the longitudinal passage 24 to a second position, or dispense position as --shown in Figure 2 wherein a bottom opening 42 in the bottom plate 34 is positioned dixectly underneath the dispenser aperture 28. Thus, solid materials in the dispenser aperture 28 are dispensed from the dispenser 10. The bottom opening 42 is not aligned with the top opening 20 50 that there iB no flow through of solid ingredients from the container 12. As shown in Figures 1 and 2, the bottom opening 42 is approximately in the centre of the container 12, thus the dispenser can be held over a cup o~ coffee or whatever is required to be filled, and ensure that ingredients will be dispensed from approximately the centre of the di~penser.
. .
Rubber feet 44 are shown fitting into appropriate sockets in the base 34 of the body member 22 so that the unit will stand on a smooth table or counter surfaces without sliding. As shown in Figure 3, machine screws 46 are provided on two sides to hold the container 12 and body member 22 including the bottom plate 34 together.
In operation, the container 12 is held in one hand and the squeeze handle 16 squeezed. This action moves the sliding member 26 in the passageway 24 to the second or dispense position and sugar or other granular or ~o~
powder ingredients in the dispenser aperture 28 are dispensed through the bottom opening 42 in the bottom plate 34. When the gripping handle 16 is released, the spring 30 pushes the sliding member 26 back to the first or fill position, and ingredients in the container 12 fill up the dispenser aperture 28 ready for the next dispensing application. In one embodiment the size of the dispenser aperture 28 represents half a teaspoon and thus one requires four squeezes of the squeeze handle 16 to obtain two teaspoons of, for example, sugar from the dispenser 10.
Another embodiment is illustrated in Figure 4 wherein the dispenser aperture 28 has a slide plate member 50 therein which moves in a larger aperture 52 of ; 15 the sliding member 26. A threaded hole 54 extends out : through the end of the sliding member 26 and a threaded rod 56 fits therein having an end attachment 58 which engages the sliding plate member 50 within the aperture 52. The threaded rod 56 extends through a slot 60 at the bottom of the squeeze handle 16 and has a knob 62 at the end of the rod 56. Thus, rotation of the knob 62 moves the threaded rod 56 backwards and forwards in the threaded hole 54 which in turn moves the sliding plate member 50 backwards and forwards in the aperture 52.
This movement changes the size of the dispenser aperture 28. For example the dispenser aperture 28 may be changed from a half tea~poon to one teaspoon or any other desired size that is required. Provi~ion is provided to prevent the sliding plate member 50 being pushed too far forward 30 thus preventing ingredients from the top opening 20 -.
falling behind the sliding plate member 50. Graduations tnot shown) may be provided on the knob 62 or adjacent the knob 62 so that the volume of the dispenser aperture 28 is known.
In the embodiment shown, the dispenser 10 is grippable in one hand and operable by squeezing the squeeze handle 16. Other types of dispensers may be provided. For example, dispensers provided in kitchen cupboards or the like may be fixed in position or may be mounted along a kitchen wall. The squeeze handle 16 may then be replaced by a plunger which simply requires a push. This is particularly true when the dispenser is attached to a wall or a shelf.
Various changes may be made to the embodiments shown herein without departing from the scope of the present invention which is limited only by the following claims.
