Description

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 or composted.

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 control.

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 product.

(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 ship.

(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.

OBJECTS AND ADVANTAGES

Accordingly, several objects and advantages of my invention are:

(a) to provide a cat litter box waste receptacle assembly with enclosure that is disposable, recyclable, and compostable,

(b) to provide a litter box not constructed of plastic or metal; but primarily from paper based materials,
