BACKGROUND--FIELD OF INVENTION
This invention is a disposable cat litter box waste receptacle
assembly, with enclosure, constructed primarily from recycled materials,
and which includes a quantity of disposable litter latrines pre-filled
with a quantity of absorbent litter.
BACKGROUND--DESCRIPTION OF PRIOR ART
The inconvenience, cost and effort of maintaining a cat litter
box is of concern to many owners, witness the number of patented
and trademarked devices which are designed to address the tasks.
Also of concern to present day humankind is the reality that recycling
and composting have become a necessity in order to protect and preserve
the environment. Cat litter waste receptacles have conventionally
been composed of plastic or polyinal and require the addition of
absorbent litter, usually clay based. In addition, repeated maintenance
and cleaning is required after they are soiled by waste before re-use.
They conventionally have not been designed to be disposed of, recycled
Several inventors have created cat litter boxes which address one
or more concerns; but fall short of solving several. U.S. Pat. No.
4779567 to Smith (1987) discloses a disposable travel type pet
litter box; however, it is a single use device which must be maintained
by cleaning and refilled with litter in order to be reused. It requires
the use of a disposable bag liner, and does not provide a dome or
enclosure for an animal to enter for privacy, tidiness and odor
U.S. Pat. No. 4732111 Runion (1987) shows a unit which includes
a disposable insert tray. Although this device is re-usable and
disposable; it requires refilling with a conventional litter material,
cleaning and maintenance for repeated use. The disposable tray is
of such construction that it would require a separate moisture proof
liner for extended and repeated use in order to prevent waste soilage.
Waste must be removed between litter refilling for extended use.
U.S. Pat. No. 5060849 to King (1990) is a dual purpose- home
and transportable disposable device. However, it to is limited to
single use. U.S. Pat. Nos. 5048465 & 5477812 (1990-91) to
Windmere is a self cleaning electromechanical litter box, constructed
of sturdy polyvinal plastic, and metal, and requires a motor, power,
a specially designed refuse collection bag, maintenance and refilling
with clumping litter exclusively. This device is complex, costly
and not intended to be recyclable or disposable.
Other inventions in this field range from simple plastic trays,
to disposable single use cardboard travel boxes, to prepackaged
disposable single use units which incorporate a plastic tray filled
with high quality anti-bacterial clay litter, such as the Johnny
Cat Toss Away.TM. First Brands Corporation, USA.
There are a multitude of innovative cat litter waste receptacles,
and several clever waste removal, cleaning and sifting devices or
systems. Such as the Self Cleaning Cat Box.TM. Roll To Clean Co.,
Canada. The polyvinal Sifting Cat Pan.TM. Van Ness Plastics, USA.
A Hooded Cat Box with air filter.TM. Doskocil Corp, USA. All of
which that were herein disclosed have inherent limitations. They
are of a permanent not disposable or recyclable nature, require
specially designed clay litter and bag liners, are costly, not ecologically
conscious in design, require separate maintenance operations to
remove waste, refill litter, and clean between soilings for extended
use, require separate packaging and supplies. Although innovative
and convenient, all cat litter waste receptacle devices heretofore
known suffer from one or more common disadvantages:
(a) The use of primarily polyvinal plastic construction results
in a permanent rather than disposable, recyclable, or compostable
(b) Plastic products are expensive to manufacture.
(c) Recycling polyvinal is a complex and costly process.
(d) Plastic is not generally considered to be compostable or biodegradable.
(e) Many existing litter waste devices require special auxiliary
supplies for use. Such as a particular type of litter, bags or liners,
air filters, and even batteries or power supplies.
(f) Prior devices and systems are often costly, complex difficult
to use, and inconvenient to clean and maintain.
(g) The common exclusion of a latrine privacy enclosure on many
allows the soiled litter to be spread about during and after use.
Lack of such an enclosure allows excessive odors to escape and is
not attractive to cats. Felines tend to be attracted to and like
to enter boxes or enclosures.
(h) Clay litter is a physically heavy material to transport and
(i) Clay litter is not a recycled or recyclable product.
(j) Existing devices often require external packaging which unnecessarily
increase the cost of manufacture and requires separate disposal
of said packaging.
(k) Many units are intended for single use and must be disposed
of once soiled.
(l) Most designs for permanent type litter waste recepticles require
ongoing separate cleaning, refilling and maintenance operations
to be performed.
(m) Of the single use disposable units, many of which are constructed
of cardboard like materials, most of this type require auxiliary
supplies and are not moisture or odor resistant. Those not made
of cardboard tend to be disposable; but not recyclable or compostable.

FIGS. 1 to 5
A typical embodiment of the present litter box assembly invention
is illustrated in FIG. 1 a perspective view of the litter box assembled
in its use configuration. In the preferred embodiment the box has
a box tray 10 made of a paper product or byproduct such as corrugated
or chipboard, which have interior moisture resistant surfaces. However;
said tray can consist of any other material that can be readily
recycled, such as
various laminated or extruded materials, fibrous materials, cloth,
wood products or byproducts, leather, metal, recyclable polyvinal
or plastic, etc. A latrine privacy enclosure cover 12 is similarly
constructed as is the box tray 10. A prepackaged litter latrine
14 with litter, is shown in place for use. A cut out removable entry
16 is shown in place functioning as an optional cat paw cleaning
device. A self adhesive deodorizing device 26 is shown in place.
In the preferred embodiment the assembled box FIG. 1 has approximately
parallel surfaces; the opposing top, sides and bottom form a shape
approximating a rectangular shaped cube. However; other shapes such
as oblong, round or rounded, or angular could be used.
FIG. 2 represents a perspective view of the box in its assembled
for transport or shipping/inverted configuration. In this position,
the bottom tray 10 acts as a top. The enclosure 12 acts as a receptacle
and shipping- transport container. A cut out removable entry 16a
opening is shown in place, a carrying handle 18 and a closure device
20 or means for securing the assembly in a closed condition during
shipping are represented.
FIG. 3 is an expanded perspective view of the litter latrine 12.
Said latrine is similarly constructed as tray 10 and enclosure 12
with its interior surface being moisture resistant. A removable
latrine seal sheet 22 keeps the prepackaged absorbent litter 24
in place during shipping, transport and storage.
FIG. 4 is a perspective representation of the litter latrine assembly
14 a-f stacked for shipping. FIG. 5 shows a perspective exploded
view with cross section of the box assembly with the litter latrine
14 in both its shipping and use position.
In the preferred embodiment the entire box assembly, FIGS. 1-2-3-4-5
is constructed of paper products or by-products. However; the entire
assembly could be constructed from any other material that can be
readily recycled, such as various laminated or extruded fibrous
material, cloth, wood products or by-products, leather, metal, recyclable
polyvinal or plastic, etc.
The manner of using the box assembly is to open it by removing
the box tray 10 as shown in FIG. 2. Then the user takes out the
litter latrines 14 a-f shown in FIG. 4. One latrine 14 is opened
to expose the prepackaged absorbent litter 24 contained inside
by removing a latrine seal sheet 22 shown in FIG. 3. The user then
inverts tray 10 FIG. 1 inserts the opened latrine 14. The assembly
is completed by removing the cut out 16 from a latrine privacy enclosure
cover 12 and placing said cut out in front of the box tray, then
placing the enclosure 12 over the tray 10 and latrine 14 as shown
in FIG. 1.
To remove and dispose of the soiled latrine 14 FIG. 1 the enclosure
12 is removed and the entire latrine 14 is removed for disposal,
recycling, or composting. A replacement latrine 14 is then opened
and inserted as previously described. The enclosure 12 is then replaced.
Upon exhaustion of unused latrines 14 a-f FIG. 4 the entire box
assembly is disposed of, recycled, composted, and replaced with
