Description
The instant invention is generally concerned with portable waste
receptacles, and more particularly relates to a receptacle which
utilizes disposable bags and provides for a flushing type operation
without requiring mechanical mechanisms or the like to provide for
a segregation of the waste received within the bag so as to
preclude the escape of pollutants or objectionable odors to the
atmosphere.
A primary object of the instant invention is to provide an
effective means for temporarily storing waste, including body
waste, in a manner whereby the waste is completely contained and
escape thereof, or odors therefrom, is effectively precluded.
In conjunction with the above object, it is also a highly
significant object of the instant invention to provide for the
confining of the waste in a simple and highly effective manner
requiring no operating mechanisms and only a simple manual
manipulation of the receptacle to completely confine the waste and
prepare the receptacle for the introduction of additional
waste.
Also of primary significance is the intention of the instant
invention to provide an effective waste receptacle which, while
highly unique in construction and operation, is simple and
inexpensive to both manufacture and use, normally being constructed
of appropriate plastic or lightweight metal.
In conjunction with the above object, it is also an object of the
instant invention to provide a waste receptacle which utilizes few
component parts, these parts being easily dismantled for cleaning
purposes.
Basically, the above objects are achieved through the utilization
of a vertically elongated generally cylindrical container which has
an offset funnel seated within the upper portion thereof. An
enlarged disposable bag, of plastic or the like, is provided within
the funnel and extends through the open spout or lower end thereof
with the bag folding about a slightly elevated crossbar and then
continuing to the lower end of the container. The fold in the bag
forms a reverse trap which, in conjunction with a small amount of
water introduced through the funnel, will effectively seal the
lower end of the bag. The waste introduced into the funnel is
selectively deposited into the lower end of the bag simply by
elevating the funnel and upper portion of the bag so as to
straighten out the trap forming reverse bends therein and allow the
waste to slide freely thereby. A subsequent reseating of the funnel
again forms the trap, alone or preferably with a small amount of
additional water introduced into the funnel.
These together with other objects and advantages which will become
subsequently apparent reside in the details of construction and
operation as more fully hereinafter described and claimed,
reference being had to the accompanying drawings forming a part
hereof, wherein like numerals refer to like parts throughout, and
in which:
FIG. 1 is a perspective view of the portable waste receptacle
completely enclosed;
FIG. 2 is an enlarged cross-sectional view taken substantially on a
plane passing along line 2--2 in FIG. 1;
FIG. 3 is an exploded perspective view of the components of the
waste receptacle;
FIGS. 4, 5 and 6 are cross-sectional views illustrating a series of
steps in the use of the receptacle;
FIG. 7 is a top plan view of the receptacle container with the
funnel and bag removed; and
FIG. 8 is a cross-sectional detail of the bar mount, taken
substantially on a plane passing along line 8--8 in FIG. 7.
Referring now more specifically to the drawings, reference numeral
10 is used to generally designate the portable waste receptacle
comprising the instant invention. This receptacle 10 includes an
enlarged vertically orientated container 12 which will normally be
generally cylindrical and within which the other component parts
are received, a lid or cover 14 sealing the top of the container 12
and confining the received components.
Within the enlarged internal chamber 16, formed within the
container 12, is a diametrically orientated bar or rod 18
positioned at or slightly above midheight and extending
transversely thereacross into supporting engagement with the
opposed portions of the container 12. The bar 18 is to be removably
supported in an appropriate manner. This can be effected by the
provision of opposed brackets or, as illustrated in FIG. 8, seats
or depressions 20 formed within the container wall. The removal of
the bar 18 when mounted as illustrated in FIG. 8 would require only
a slight flexing of the container and an upward swinging of one end
of the bar 18.
An enlarged funnel 22 is provided within the upper portion of the
container chamber 16 and so configured or tapered as to position
the lower discharge end or spout 24 thereof below and to one side
of the crossbar 18. The upper end of this offset funnel 22 has an
outwardly rolled or beaded edge 26 thereabout which rests on a
series of inwardly projecting shoulders or ledges 28 provided about
the upper portion of the chamber 16 below the top edge of the
container a slight distance whereby the upper edge 26 of the funnel
22 will, when thereon, be generally coextensive with the upper edge
of the container.
The final major component of the receptacle 10 is an elongated
disposable bag 30 of a suitable nonporous nature, preferably
constructed of plastic. This bag 30 lines the interior of the
funnel 22 and has the upper edge portion thereof folded outwardly
about the upper edge 26 of the funnel 22 and downward a short
distance about the outer periphery of the funnel 22 where it is
secured by an encircling elastomeric band 32. In order to assist in
the retention of this upper edge of the bag, a groove 34 can be
provided about the exterior of the upper portion of the funnel 22
for a reception of the band-clamped edge portion of the bag 30.
This recess or groove 34 can be formed by the utilization of an
annular bead or rib 36 provided about the funnel 22 in slightly
spaced relation below the funnel edge 26. The lower portion of the
bag extends through the open lower end or spout 24 of the funnel 22
and then bends or is folded upwardly over the bar 18 and downwardly
into the bottom of the container chamber 16, thus forming a reverse
bend in the bag 30 along the length thereof with the bag, as it
passes over the bar 18, being completely or substantially
completely collapsed on itself. There is thus formed an effective
reverse bend trap between the upper and lower portions of the bag
30. The effectiveness of this trap will be further enhanced by the
introduction of a small amount of water through the funnel 22 and
into that portion of the bag 30 immediately below the funnel spout
24, note for example FIG. 2.
In use, waste will be introduced into the bag lined funnel 22,
preferably falling directly into the normally provided small water
reservoir. Subsequent to the introduction of the waste, noting
particularly the sequence of steps illustrated in FIGS. 4, 5 and 6,
the funnel 22 is elevated and, if so desired, shifted slightly
laterally so as to eliminate the reverse bends or trap within the
bag 30 so as to allow the waste to fall into the chamber received
lower portion of the bag 30. The funnel is then repositioned, which
automatically places the spout 24 below and to one side of the
crossbar 18, so as to redefine the trap and completely confine the
waste, and any odors emanating therefrom, in the lower portion of
the bag 30. As previously stated, the effectiveness of the trap can
be substantially enhanced by again introducing a small amount of
water or other appropriate liquid, such as a disinfectant which
will be confined within the bag immediately below and possibly
within the lower portion of the funnel 22. Once the bag 30, below
the crossbar 18, has filled, the bag 30 will be tied off
immediately below the funnel 22 and removed therefrom in an obvious
manner for disposal. The portable receptacle will then be prepared
by the mounting of a new bag.
It will be readily appreciated from the above that the waste is at
all times confined within the bag itself, thus avoiding any
contamination of the remainder of the receptacle and providing for
a complete disposal of all of the waste at the time of the disposal
of the bag itself. Should it become necessary for any reason to
clean the remainder of the receptacle, the readily separable nature
of the simple component parts thereof will make this an easy
task.
While not specifically referred to supra, should it be desirable,
an outwardly projecting handle 38 can be provided on the upper end
of the funnel 22 so as to facilitate its removal. The provision of
such a handle 38 would of course require either a slot within the
upper edge portion of the bag 30 or a folding of the edge about the
handle. In neither case will this interfere with the proper
mounting of the bag. Further it should be appreciated that the
upper edge of the container 12, in conjunction with the outwardly
rolled upper edge 26 of the funnel 22, can form a seat for the use
of the receptacle as a toilet.
From the foregoing, it should be appreciated that a highly unique
waste receptacle has been defined wherein a waste-receiving bag is,
in effect, formed into an upper waste-receiving portion and a lower
waste-storing portion divided by a trap which is selectively
removed to enable a movement of the waste from the receiving
portion to the storing portion and subsequently redefined to seal
the waste within the storing portion.
The foregoing is considered as illustrative only of the principles
of the invention. Further, since numerous modifications and changes
will readily occur to those skilled in the art, it is not desired
to limit the invention to the exact construction and operation
shown and described, and accordingly all suitable modifications and
equivalents may be resorted to, falling within the scope of the
invention as claimed.
