DEVICE FOR MEASURING AND DISPENSING FREE FLOWING MATERIALS
Abstract
The present invention relates to a measuring and dispensing
device having a container cap securely fastened to a container by
screw threads or other suitable means; a two piece rotatable
metering drum connected to the cap by a rotatable, snap-action
ring; and an exit spout on the opposite end of the metering drum
attached to the drum by a rotatable, snap-action ring. An objective
in the development of the present device was to reduce the height
of the metering drum which is achieved by splitting the metering
drum along a parting line, and then permanently joining the two
parts by a non-rotatable locking snap-action ring so that the
entrance and exiting openings to the metering drum are
approximately 3/8 inch in diameter while the interior of the
metering drum chambers vary in size to accommodate the 1/4, 1/2,
and 1 teaspoon measurement amounts.

Description
FIELD OF THE INVENTION
[0001] This invention relates to a measuring and dispensing device
which can be used for powdered and granular materials, and is
particularly suitable for dispensing spices, but it may be used
with other kinds of free flowing materials such as medicines, tooth
powder, sugar, coffee, and the like.
BACKGROUND OF THE INVENTION
[0002] Many people working in the culinary arts, and homemakers
have used measuring spoons over the years to measure liquids, and
free flowing materials of various kinds. There are obvious
disadvantages to the use of measuring spoons such as having them
readily available for use, having to open the condiment or other
jar, and scooping out the correct amount without spilling the
material on the counter top or floor. There has been a need for
measuring devices which are attached directly to the container, and
inventors have responded with alternative concepts for measuring
and dispensing all types of liquids and free flowing materials by
means of container tops having chambers within them. The present
device has features that make it suitable for mounting on standard
31/2 ounce and 51/2 ounce spice jars which have a small exit
opening which has an internal diameter of 1.25 inches, thereby
making it difficult to keep the height of the measuring device,
when measuring 1/4, 1/2, and 1 teaspoon amounts, to a minimum. The
standard spice jars are small, approximately 31/2 inches in height
for a 31/2 ounce jar. Replacing the standard cap, on these small
jars, with a measuring device which is much longer than 1 inch in
height creates multiple problems. Spice jars with measuring caps
that are too long do not fit on many multiple level spice racks. In
multiple level spice racks that can accommodate the added length of
the spice jar, removal and replacement is complicated by the small
clearance between the top of the measurement cap and the next level
of spices. Long measuring and dispensing jar tops on such a small
jar have a poor appearance, and become top heavy especially when
lighter weight spices such as flaked parsley or flaked oregano are
used. A longer jar top also has the disadvantage of having smaller
holes in the entrance and exit openings for the lower volumes of
spice such as 1/4 teaspoon. Smaller diameter chambers with longer
lengths and smaller entrance and exit openings also create flow
problems.
[0003] The Palmer patent, U.S. Pat. No. 4,832,235, shows a
measuring design depicted in FIG. 1B. The Palmer design has a long
length, approximately 2 inches, because the central shaft, and the
largest chamber opening to accommodate a 1 teaspoon measurement
size, take up a large space within the very limited 1.25 inch
diameter of the inside of the exiting diameter of a standard spice
jar. The Palmer design must be rotated 90 degrees to move between
an open chamber and the next chamber. The 90 degree rotation for
each of 4 filling positions restricts the cross-section of the 1
teaspoon size chamber to a 90 degree sector. This restriction along
with the unusable space taken up by the central shaft requires that
the 1 teaspoon size chamber has to be approximately 2 inch in
length. Also, in the Palmer design the required long length of the
drum makes the 1/4 teaspoon entrance and exit diameters of the drum
small, less than 1/4 inch diameter, to achieve the required
volume.
[0004] Other dispensing devices include Slayton, U.S. Pat. No.
3,695,487; Lee, U.S. Pat. No. 3,308,995; Fridman, U.S. Pat. No.
5,271,535; Saunders, U.S. Pat. No. 2,515,735; Tepper, U.S. Pat. No.
2,898,010; and, Bode, U.S. Pat. No. 3,269,612. These patents are
all related to dispensing measured amounts of various free flowing
materials. In Slayton, "pockets" are used to measure the amount of
material selected. The design has a central shaft which reduces the
available space for the pocket opening, and the opening width of
the largest pocket is controlled by the sector size. The restricted
area within a standard spice jar establishes the height of the
pockets for the 1 teaspoon size. The measurement pocket is too high
with the design as shown in the patent for a 1 teaspoon
measurement. Fridman, Saunders, Tepper, and Bode all have the
limitation of central shafts, which occupy space within the
allowable area of a standard spice jar cap opening, thereby
limiting the size of the available measurement chamber opening, and
therefor making a low measurement chamber height unobtainable.
SUMMARY OF THE INVENTION
[0005] The present invention consists of a jar top device
applicable to all types of containers but specifically suitable for
use with standard spice jars of the 31/2 ounce and 51/2 ounce
sizes, that allows for measurement and dispensing of desired
quantities of free flowing material. The spice jar top has three
primary parts, a jar cap which replaces the standard spice jar cap,
a metering drum section, and a spout. The cap has a threaded
attachment which is screwed onto the spice jar, and an inclined
interface ring which permits attachment to a metering drum by a
rotatable, snap-action ring located on the metering drum. The
metering drum has three measuring chambers for measuring 1/4
teaspoon, 1/2 teaspoon, and 1 teaspoon quantities. The metering
drum is attached to the spice jar cap at the entrance end of the
chambers by the rotatable, snap-action ring. An inclined interface
ring is located at the exit end of the chambers for attachment to
the spout. The spout is attached to the metering drum at the exit
end of the chambers by a rotatable, snap-action ring located on the
spout.
[0006] The jar cap has a single opening approximately 3/8 inch in
diameter which serves as the entrance opening for the spices coming
from the jar into the measuring chambers in the metering drum. The
entrance opening matches three further openings located on the
entrance end of the metering drum which three openings are also
approximately 3/8 inch in diameter. The metering drum has three
measuring chambers, a 1/4 teaspoon, 1/2 teaspoon, and 1 teaspoon
sizes, which have matching, approximately 3/8 inch diameter
entrance openings at the entrance end, and matching, approximately
3/8 inch diameter exit openings at the exit end of the metering
drum. The center portion of the metering drum is expanded in size
from the entrance and exit openings to provide the fall measurement
volume within a reduced length, of approximately 1 inch, of the
metering drum. The choice of 3/8 inch diameters at the metering
drum interface with the jar cap and spout permits 6 rotational
positions. Three positions have approximately 3/8 inch diameter
openings aligned to allow flow into or out of the measuring
chambers of the metering drum, and three positions block flow into
or out of the measuring chambers of the metering drum. To achieve
the openings and volumes within a metering drum height of
approximately 1 inch the metering drum is split into two parts. The
two parts of the metering drum are securely locked in place by a
locking, snap-action ring. The ring is located on the part of the
metering drum furthest away from the spice jar, and mates with a
locking interface ring located on the part of the metering drum
nearest to the spice jar. The two parts of the metering drum are
also aligned during assembly and prevented from rotation by
anti-rotation tabs located on the part nearest the spice jar which
mate with anti-rotation grooves located on the part furthest from
the jar.
[0007] In the present invention the entrance and exit openings of
each of the chambers is intentionally sized at an approximately 3/8
inch diameter which is accomplished by the split metering drum
design. The larger volume contained within the drum does not affect
the size of the entrance and exit openings. The 3/8 inch diameter
entrance and exit openings were selected to provide a sufficient
opening size to improve the flow of smaller measured amounts, such
as the 1/4 teaspoon amount, through the openings, and also to
accommodate larger spices such as flake sized spice materials which
have difficulty passing through holes which are smaller than 3/8
inches in diameter, especially if the length of the chamber is
long. Another benefit of using 3/8 inch diameter entrance and exit
holes is that blank spaces can be accommodated between the entrance
and exit openings so that approximately 60 degrees of rotation in
either direction from the entrance or exit hole blocks the path of
material either into or out of the drum. This feature allows the
measured amount to be pre-selected in the upright position of the
spice jar and then the jar can be inverted for filling that
chamber. Then, once the chamber is filled, the chamber entrance
hole can be closed, by rotation of the cap to a blank space,
thereby blocking any further flow of spice into the chamber. The
spice can then be stored in the chamber or dispensed. If it is
desired to dispense the spice the exit hole in the spout is then
opened by rotating the spout from a blank space to the open
position, while the spice jar is still in the inverted position,
and the spice will be dispensed.
[0008] The spice jar top described herein preferably, but
optionally, has arrows and markings indicating the locations of the
measuring chambers for the 1/4 teaspoon, 1/2 teaspoon, and 1
teaspoon sizes, and further preferably but optionally, raised bars
to indicate the location of blocked spaces. The desired amount of
spice is dialed into the device by rotating the rotatable,
snap-action ring furthest away from the spice jar to a blocked
position, and then rotating the rotatable, snap-action ring nearest
to the spice jar to the desired position. Inverting the jar then
fills the measuring chamber. The entire spice jar top is preferably
made from clear polypropylene plastic material, but other materials
may be used. The filling of the selected chamber is observed
visually through the clear plastic metering drum to insure that it
is completely filled then the rotatable, snap-action ring located
nearest to the spice jar is rotated to a blocked position so no
further contact is made between the spices within the spice jar and
the measuring chamber. Then, the rotatable snap-action ring located
at the exit spout is rotated to the open position to allow the
spices to flow out of the measuring chamber.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0021] The present invention is described in further detail as
follows:
[0022] FIG. 2A shows a cross-section of the entire measuring and
dispensing device and illustrates the relationship of the parts to
each other. The device has a jar cap 20; a metering drum 21
consisting of two parts, a cap to metering drum interface disc 23,
and a primary containment drum 35; and an exit spout 22. The jar
cap 20 has an internal thread 44, and an inclined interface ring 29
on one end, shown in FIG. 2E. The cap to metering drum interface
disc 23 has a rotatable, snap-action ring 30 on one end, and an
inclined interface ring 36 on the opposite end, shown in FIGS. 2E
and 2F. The primary containment drum 35 has a locking, snap-action
ring 37 on one end, and an inclined interface ring 32 on the
opposite end, shown in FIGS. 2A, 2F and 2G. The exit spout 22 has a
rotatable, snap-action ring 33 on one end, shown in FIG. 2G. The
primary containment drum 35 has 1/4 teaspoon, 1/2 teaspoon, and 1
teaspoon chambers designated, respectively, as 26, 27, and 28
contained therein, shown in FIG. 2D.
[0023] The jar cap 20, located nearest to the spice jar 19,
replaces the standard spice jar cap. It has an internal thread 44,
which mates with the standard spice jar 19 threaded end. The jar
cap 20 has an external, inclined interface ring 29, shown in FIG.
2E, on the end of the cap furthest away from the spice jar 19, for
mating with a rotatable, snap-action ring 30. The snap-action ring
is a part of the cap-to-metering drum interface disc 23, shown in
FIGS. 2A and 2F, which is located on the spice entrance end of the
metering drum 21. The described interface permits rotation of the
metering drum 21 with respect to the jar cap 20 while providing
interface pressure between the mating planar faces 41 of the jar
cap 20 and metering drum 21. The interface pressure is used to
prevent leakage between the planar faces 41 when the device is
rotated from position to position. The angle on the incline of the
interface ring 29 is designed to provide sealing pressure directed
inward towards the vertical axis of the metering drum 21 while, at
the same time, providing interface sealing pressure between the
mating planar faces 41 of the jar cap 20 and the metering drum 21.
The angle of the incline is about 60 degrees as shown in FIG. 2E.
An approach ramp 31 is provided on the external surface of the jar
cap 20 at the end furthest away from the spice jar to permit hand
assembly between the jar cap 20, and the metering drum 21. The jar
cap 20 has a single opening 24, approximately 3/8 inch in diameter,
on the planar surface 42 nearest the metering drum 21. The opening
lies completely within the internal 1.25 inch inside diameter of
the spice jar 19 so as to allow spices to enter the opening
freely.
[0024] The metering drum 21 is split into two parts. The part
nearest the spice jar 19 is the spice cap-to-metering drum
interface disc 23, shown in FIGS. 2A and 2F. The spice
cap-to-metering drum interface disc 23 has a rotatable, snap-action
ring 30, shown in FIG. 2E, on the end nearest to the spice jar 19,
and an external inclined interface ring 36, shown in FIG. 2F, on
the end furthest away from the spice jar 19. The spice
cap-to-metering drum interface disc 23 has three, approximately 3/8
inch diameter, entrance openings at the planar surface 42 nearest
to the spice jar 19, and openings matching preferred enlarged size
openings, located in the primary containment drum 35, furthest away
from the spice jar 19. Enlarged openings in the primary containment
drum 35 are preferred in order to keep the length of the
measurement drum 21 as short as practical.
[0025] The 3/8 inch diameter openings in the cap-to-metering drum
interface disc 23 have a transition 45 from the 3/8 inch diameter
sizes to their respective measurement chambers, 1/4 teaspoon, 1/2
teaspoon, and 1 teaspoon, 26, 27, and 28 respectively, located in
the primary containment drum 35. The primary containment drum
chambers 26, 27, and 28 have a transition 45 from the measurement
chambers to the 3/8 inch diameter openings at the exit spout 22
interface. The transition 45 from the 3/8 inch diameter inlet and
exiting openings of the metering drum 21 to the measuring chambers
26, 27, and 28 have straight sides between them, but other
transition contours can be used. The increased volumetric feature
provided by the split metering drum permits the length of the
metering drum 21 to be shortened, controlled by the allowable
volume of the largest, 1 teaspoon, measurement. The metering drum
21, shown in FIG. 2A, is approximately 1 inch in length although it
could be made even shorter by increasing the cross-section of the
largest, 1 teaspoon, chamber 28. But, as described herein, there is
a practical limit for the length of the metering drum 21 related to
operational considerations.
[0026] The primary containment drum 35 has the measuring chambers
26, 27, and 28, shown in FIG. 2D, contained therein. Each of the
chambers have a center-line on the same diameter as the entrance
openings located on the cap-to-metering drum interface disc 23, and
the opening located in the jar cap 24, as well as the exit spout
opening 25. This permits all openings to be aligned to each other
during filling and dispensing of spices. The primary containment
drum 35 has a locking, snap-action ring 37, shown in FIG. 2F,
located on its exterior surface at the end nearest to the spice jar
19, and an inclined interface ring 32, shown in FIG. 2G, located on
its exterior surface at the end furthest away from the spice jar
19. The inclined ring 32 mates with the rotatable, snap-action ring
33 on the exit spout 22. The primary containment drum 35 has three
approximately 3/8 inch openings located at the planar interface 43
nearest to the exit spout 22. The 3/8 inch diameter exit openings
on the containment drum 35 bring the enlarged chambers back to the
original entry opening size to interface with the 3/8 inch aperture
25 located in the exit spout 22. The locking snap-action ring 37,
shown in FIG. 2F, on the primary containment drum 35 engages the
locking interface ring 36, on the cap-to-metering drum interface
disc 23, and is prevented from rotating by anti-rotation tabs 40
located on the cap-to-metering drum interface disc 23, and the
anti-rotation grooves 41, shown in FIG. 2D and 2F, located on the
primary containment drum 35. There are four anti-rotation tabs 40,
and four mating anti-rotation grooves 41, although other numbers of
tabs and grooves could be used. One tab and groove is located 10
degrees off the vertical so that the matching openings in the
metering drum interface disc 23, and the primary containment drum
35 can only be aligned in one orientation. This insures that the
correct aperture sizes will match each other in the mating parts.
Further, the anti-rotation tabs 40, and anti-rotation grooves 41
prevent rotation of the two sections of the metering drum 21 from
rotating with respect to each another.
[0027] The locking snap-action ring 37, shown in FIG. 2F, has a
flat 38, on the inside surface of the bulb end of the ring 37. The
flat is angled about 30 degrees from the horizontal, and mates with
the about 30 degree flat surface 39 on the locking interface ring
36. Flats 38 and 39 cooperate to provide a high interface pressure
between the two sections of the metering drum 21 to prevent
leakage.
[0028] The exit spout 22 is connected to the metering drum using an
inclined interface ring 32 similar to the design of the interface
used to attach the jar cap 20 to the metering drum 21. The
rotatable, snap-action ring 33 is wider than the rotatable,
snap-action ring 30 at the cap interface in order to provide a
better gripping area for rotating the exit spout 25 as the spout is
smaller in diameter than the rotatable, snap-action ring 30 used to
attach the metering drum 21 to the jar cap 20. The exit spout 22
has exit spout opening 25, approximately 3/8 inch in diameter, for
final dispensing of the desired quantity of spices.
[0029] FIG. 3B shows the complete assembly of the standard size
31/2 ounce spice jar 19 with the measurement and dispensing device
mounted to it. FIGS. 3A and 3B also show arrows and bars used for
aligning the three primary sections of the device to permit
filling, and dispensing of the respective amounts, 1/4, 1/2 and 1
teaspoon, of spices. If the arrows are aligned as shown in FIG. 3A
the device can be used to sprinkle the desired amount of spices
because a straight-through opening will be provided. If a table
spoon is required the device can be used by measuring three
teaspoons since three teaspoons are equal to one tablespoon.
