1. Field of the Invention
The present invention relates generally to the field of personal sanitation devices, and more specifically, to a portable urine bag.
2. Description of the Related Art
People can become stressed, uncomfortable and often embarrassed when they have a need to urinate, but conventional plumbing is not available or conveniently accessible. This group of people may include healthy individuals as well as sufferers of stress and urgency incontinence who have very limited time to respond to the need to urinate. In addition, those who are wheelchair-bound, travelers in private aircrafts, commuters, vacationers, boaters, rafters, hikers, rock climbers, campers, hunters, fishermen, utility workers, truckers, and military personnel in the field, in combat, on maneuvers or in convoys all may suffer at some time from having to urinate without access to a proper facility. Emergency situations such as hurricanes, earthquakes, power outages, mining accidents, etc. may also disrupt plumbing, creating a need for a safe and sanitary way to urinate.
What is needed is an apparatus that is portable, safe and easy to use, and preferably biodegradable and into which an individual may urinate when other facilities for this purpose are unavailable. The ideal apparatus can be used multiple times and would include a means for controlling odor and facilitating waste decay.

In a preferred embodiment, the bag portion has a length, the plastic collar lies inside of the bag portion and is adhered to a portion of the bag portion, and the plastic collar extends into the bag portion approximately one-fifth of the length of the bag portion. In yet another preferred embodiment, the bag portion has a length, the plastic collar lies inside of the bag portion and is adhered to a portion of the bag portion, and the plastic collar extends into the bag portion approximately one-eighth to approximately one-third of the length of the bag portion.
In a preferred embodiment, the bag contains a composition comprised of a superabsorbent polymer, an odor control agent, and/or a decay catalyst. The superabsorbent polymer is preferably sodium polyacrylate. The odor control agent is preferably zeolite. The decay catalyst is preferably an enzyme found in yeast. In a preferred embodiment, the enzyme is selected from the group consisting of sucrase, zymase, maltase, lactase, hexosephosphatase, reductase, carboxylase, melibiase, and endo-tryptase.
In a preferred embodiment, each of the superabsorbent polymer, odor control agent, and decay catalyst has a percentage by weight of the composition, and the percentage by weight of the superabsorbent polymer is in the range of 0.1% to 99%, the percentage by weight of the odor control agent is in the range of 0.1% to 25%, and the percentage by weight of the decay catalyst is 0.1% to 15%. In yet another preferred embodiment, the percentage by weight of the superabsorbent polymer is 84%, the percentage by weight of the odor control agent is 15%, and the percentage by weight of the decay catalyst is 1%. Preferably, the composition comprises approximately 0.0302 pounds of sodium polyacrylate, approximately 0.0055 pounds of zeolite, and approximately 0.0003 pounds of yeast.
In a preferred embodiment, both the bag portion and the plastic collar are comprised of a biodegradable material.

The present invention is a portable urine bag with a plastic collar that is specifically designed to facilitate use, comfort and sanitation. The bag also contains agents that will cause the urine to solidify within seconds, facilitate waste decay, and control odor. The present invention is discussed more fully below in connection with
In the embodiment shown in
Sodium polyacrylate is a sodium salt of cross-linked polyacrylic acid. It is a white, granular, odorless polymer that yields a gel-like material with the addition of water. It is insoluble in water and causes extremely slippery conditions when wet. It is not regulated as a hazardous material; however, the respirable dust is a potential respiratory tract irritant. The particle size distribution necessary must be between 1 and 1000 microns in order to effectively come into contact with the urine, and the absorption of deionized water is preferably greater than 100 gram per gram. Preferably, the sodium polyacrylate has a teabag absorption of 0.9% sodium chloride of at least 20 grams per gram. The apparent bulk density of the sodium polyacrylate is preferably 500 to 1000 grams per liter, and the percent moisture is preferably 0% to 10%. Sodium polyacrylate is capable of absorbing and retaining amounts of water several times its own weight under a variety of conditions.
A deodorizing agent such as, but not limited to, zeolite will absorb offensive odors. Additional deodorizing agents such as kaolin, clay, talc, cornstarch, essential oils (such as, but not limited to, lavender, thyme, thieves, mint, wintergreen, spearmint, lemon, cherry, citrus, grape, etc.) may be used in lieu of or in addition to zeolite. Zeolite is comprised of a porous structure of negatively charged ions and is recognized for its ability to actively contain odors such as hydrogen sulfide gases, indoles and skatoles. Zeolite is naturally absorptive and traps hydrogen sulfide and other gases by means of its structure, thereby reducing the odor associated with human waste.
The decay catalyst included in the composition of the present invention is preferably an enzyme found in yeast. Saccharomyces cerevisiae (common bread yeast) is an all-natural decay catalyst that, in the presences of liquid waste, produces enzymes that actively break down contaminants (e.g., blood or urinary tract pathogens) found in liquid waste. In addition, Saccharomyces cerevisiae facilitates the decay of waste products such as feces and emesis, which may also be present. Among the catalytic enzymes found in Saccharomyces cerevisiae are sucrase, zymase, maltase, lactase, hexosephosphatase, reductase, carboxylase, melibiase, and endo-tryptase.
As described above, the present invention is portable, easy-to-use, unisex and biodegradable. It preferably contains a non-toxic blend of superabsorbent polymer preferably in powder form, a natural odor control agent, and enzymes in an all-natural decay catalyst. (As used herein, the term “superabsorbent polymer” means a polymer that can absorb and retain extremely large amounts of a liquid relative to its own mass.) The preferred composition will turn up to 24 ounces of urine to a solid in a matter of seconds. When used and sealed, the bag and its contents are easily disposed of in conventional solid waste streams, such as dumpsters, trash cans, trash bins, landfills, and the like.
As the human population increases, problems associated with urination are compounded. These problems include, but are not limited to, contact with unsanitary liquid mess in spilling or splashing, the potential spread of disease, and odor. These problems are alleviated by the present invention, which provides a portable and sanitary device that can be used for urination purposes virtually anywhere. In addition, the present invention is small and light-weight and may be carried in a pocket, purse or glove box.
Although the preferred embodiment of the present invention has been shown and described, it will be apparent to those skilled in the art that many changes and modifications may be made without departing from the invention in its broader aspects. The appended claims are therefore intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
