DEVICE FOR DIRECTING FOOD WASTE INTO GARBAGE DISPOSAL INLET
Abstract
A device for safely directing food waste through a flexible
cover guard and into the inlet of a garbage disposal unit. The
device comprises a pusher-scraper blade. Integrally formed at the
end of the pusher-scraper blade is a hand grip. Auxiliary pusher
blades are formed along the sides of the pusher-scraper blade and
extend partially therealong at right angles thereto. The auxiliary
pusher blades extend lengthwise along the pusher-scraper blade from
the vicinity of the hand grip to a point removed from the free end
of the pushing-scraping blade. The auxiliary blades serve to
facilitate the opening of the flexible cover guard so that food
waste passes from a sink into the inlet of a garbage disposal unit.
The hand grip is sufficiently large so that it cannot advance
beyond the cover guard and pass into the garbage disposal unit. The
pusher-scraper blade is sufficiently short so that even when
inserted fully through the cover guard, it will not contact the
moving parts of the garbage disposal unit.

Description
BACKGROUND OF THE INVENTION
Garbage disposal units generally have an inlet which is covered by
a rubber or plastic guard. The guard is generally separatd radially
into a plurality of flaps. The flaps can be pushed open by the
exertion of pressure thereupon as by pushing food waste through the
guard and down into the garbage disposal unit.
In the past, it has been the custom of housewives to push the food
waste into the garbage disposal unit using their fingers, spoons,
spatulas, and the like. Clearly, this is not a safe procedure,
since if the garbage disposal unit is operating, the fingers,
spoons, spatulas, or the like can become enmeshed with th moving
parts of the garbage disposal unit, thereby causing great harm to
the hand, spoon, or spatula, as well as to the garbage disposal
unit.
Accordingly, it is an object of the present invention to provide a
device for safely and sanitarily directing food waste through the
inlet of a garbage disposal unit.
Another object of the present invention is to provide a device
which can be used to scrape food off plates or off a sink bottom
and to eliminate direct hand or kitchen utensil contact of the food
waste in moving the food waste directly through the guard inlet of
a garbage disposal unit.
A further object of the present invention is to provide a device
for safely and sanitarily directing food waste through the guard
inlet of a garbage disposal unit in which the device is
proportioned so that even when inserted as far as possible through
the guard inlet, the device cannot contact the movable parts within
the garbage disposal unit.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view of the device of the present invention
for directing food waste into a garbage disposal unit.
FIG. 2 is a front elevation view of the device shown in FIG. 1.
FIG. 3 is an end elevation view of the device shown in FIGS. 1 and
2.
FIG. 4 is a vertical cross-sectional view of the device shown in
FIGS. 1-3, taken along line 4--4 of FIG. 2.
SUMMARY OF THE INVENTION
A device for safely and sanitarily directing food waste through the
inlet of a garbage disposal unit comprising: a pusher-scraper
blade; a hand grip attached to the end of the pusher-scraper blade
opposite the pushing-scraping end thereof; and at least one
auxiliary pusher blade formed along the side of said pusher-scraper
blade and extending lengthwise along said pusher-scraper blade,
said auxiliary blade serving to facilitate the opening of the
flexible cover guard of the inlet from a sink into a garbage
disposal unit.
The pusher-scraper blade and the auxiliary pusher blade or blades
must, of course, be small enough to be insertable into a garbage
disposal unit and large enough to force open the flaps of said
unit.
Preferably, the auxiliary pusher blade is attached perpendicularly
to said pusher-scraper blade along the perpendicular bisector
thereof and spaced from the free end thereof; preferably, the
device includes two auxiliary pusher blades each attached
perpendicularly to said pusher-scraper blade along the
perpendicular bisector thereof, said two auxiliary pusher blades
being attached to said pusher-scraper blade on opposite sides
thereof. It is preferred that the manual grip be large enough so
that it cannot pass through the flexible cover guard and into the
inlet of a garbage disposal unit. It is also preferred that the
pusher-scraper blade by short enough so that even when inserted
fully into a garbage disposal unit it will not contact the movable
parts within said unit. In the exemplary embodiment, the
pushing-scraping end of said pusher-scraper blade is rounded to
reduce scratched plates and sinks which contain garbage disposal
units. It is also preferred that the gripping means includes a hole
for hanging the device from a hook means, e.g., a nail or the like,
whereby the device can be mounted nearby a sink. It is further
preferred that the gripping means be integral with the
pusher-scraper blade.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Illustrated in FIGS. 1--4 is the device 9 of the invention which
comprises a pusher-scraper blade 10 having a rounded
pushing-scraping end 11. A handle 12 is attached to the
pusher-scraper blade at the end thereof 13 opposite the
pushing-scraping end 11. The handle 12 is adapted for easy manual
gripping in that it contains a hole 14 wherein the four fingers of
a hand may be inserted and a gripping portion 15 which rests in the
palm of the hand. The handle further contains a second hole 16,
whereby the device may be hung vertically from a hook or the
like.
The width of the handle extending from side 17 thereof to side 18
thereof is large enough so that the handle and, hence, the entire
device, cannot pass through a guard into a garbage disposal
unit.
The device 10 also comprises two auxiliary pusher blades 19 and 20,
each auxiliary pusher blade being disposed perpendicularly to the
pusher-scraper blade 10 along the perpendicular bisector thereof,
said two auxiliary pusher blades being disposed to said
pusher-scraper blade on opposite sides thereof. The auxiliary
blades 19 and 20 in the exemplary embodiment extend from the hand
grip 12 to a point removed from the free end of the pusher-scraper
blade 10. The handle 12, the pusher-scraper blade 10 and the
auxiliary blades 19 and 20 are preferably integrally formed.
In operation, the pusher-scraper blade 10 is used to scrape food
off plates and/or the sink bottom and onto the flexible cover or
splash guard of a garbage disposal unit (not illustrated). The
pusher-scraper blade 10 is also used to push food waste through the
flexible cover guard and into the inlet of a garbage disposal unit.
It is in this later operation that the leading edges of the
auxiliary pusher blades 19 and 20 become useful in that they serve
to gather and contain food waste in front of the blades and to
cause the guard inlet of the garbage disposal unit to open
sufficiently to allow the relatively unhindered passage of food
waste into the garbage disposal unit. It also reduces drawback of
the food waste. The handle 12 is sufficiently wide so that it
cannot pass through the flexible cover guard into the garbage
disposal unit. Further, the pusher-scraper blade 10 is sufficiently
short so that even when the device is inserted as far as possible
through the flexible cover guard it will not contact the movable
parts within the garbage disposal unit.
It is desired in the operation of the device 9 that the
pusher-scraper blade 10 extend beyond the auxiliary pusher blade or
blades 19 and 20, since this enables the scraping function of the
pusher-scraper blade to be implemented.
In the preferred embodiment, the device 9 is made from a
semi-rigid, durable plastic, such as polyethylene, which can be
washed in a dishwasher. In the exemplary embodiment, the device 9
has the dimensions hereinafter set forth. The width of the handle
12 from side 17 to side 18 is approximately 41/2 inches. The length
of the pusher-scraper blade 10 is approximately 41/4 inches from
that portion of the handle 12 which in operation approaches nearest
to the garbage disposal unit (the side 21). The pushing edge of
edges 22 of the auxiliary pusher blade or blades 19 and 20
preferably end at about 1 inch from the pushing-scraping edge 11 of
the pusher-scraper blade 10.
