BACKGROUND

1. Field
This application relates to a flushable urinary device for preventing urine-splatter on and around a toilet during urination from a standing user of the toilet.
2. Prior Art
The usage of urinals is a known method to urinate in most public restrooms. However, most residences and many commercial places do not offer the convenience of urinals. Therefore, toilets designed to receive human waste from a sitting position are also used for directing urine stream from a standing position. In the process, however, urine splatters on and around the toilet, no matter how careful the users may be. Many women, out of no choice, direct urine into a toilet from standing position to avoid germs and the mess on the toilet seats in public restrooms of airports, theaters etc. The urine splatter results in a non-hygienic condition and requires additional cleaning on and around the toilet. There is a solution needed for this problem.
Several attempts have been made in the past to combine a urinal and a toilet. U.S. Pat. No. 6,408,449 issued to Aguirre (2002) disclosed a toilet assembly in combination with a urinal. Most existing bathrooms do not have the extra space required to add a urinal. In U.S. Pat. No. 5,655,230 issued to Corbin (1997), and in U.S. Pat. Nos. 3,412,408 and 3,500,480 issued to Michal (1968 and 1970 respectively), urinal attachments for toilets were presented. These urinal attachments require skilled personnel to install them. They incur extra expenses and inconveniences. Other prior art devices include U.S. Pat. Nos. 3,822,419; 4,137,579; 4,180,875; and 4,750,219. There are female urinary devices also designed for use from a standing position. U.S. Pat. No. 6,202,225 issued to Beck et al provides a non-flushable female urinary device. All these prior art devices for urinary use of toilets are not flushable. Also, they have not solved the problem of urine splatter to any degree of satisfaction. A pressing need exists in the art for a practical, effective and affordable prevention of urine-splatter. The present invention is very affordable, hygienic and is a simple solution to prevent urine splatter on and around the toilets. The deficiencies associated with the prior arts and conventional urinals are not present with the present invention.

SUMMARY OF THE INVENTION

A flushable urinary device for directing urine into a toilet from a standing user comprises a flushable funnel. The funnel has an inlet end, an outlet end and a passage between the two ends. The inlet end is adapted to register with the outlet of urethra of the user. The outlet end is adapted to direct urine into the toilet. A plurality of walls forms a passage between the inlet end and the outlet end of the funnel. Urine is directed from the standing user into the inlet end of the funnel, flows through the passage and exits the funnel through the outlet end and flows into the toilet. The funnel is made of a bio-degradable material configured to retain its substantial strength and shape temporarily when wetted. The funnel includes at least one bendable tail portion adjacent a portion of one of the ends. The tail portion forms a handle to be grasped by the user. The funnel has transitory surface water repellency to at least one surface of the funnel without impairing the ability of the funnel to be disposed of by flushing. The funnel material may have a minimum wet strength resin selected from a group comprising melamine formaldehyde, urea formaldehyde, and a neutral cure wet strength material. The funnel may be tapered between the inlet end and the outlet end. The funnel may be part of a nested stack of the funnels. The nested stack may be placed on a cardboard core. There may be a protrusion forming a lip extending outwardly and around one of the ends of the funnel around the plurality of walls. The lip is configured to hold the funnel in place. The funnel may have the inlet end as the same size as the outlet end. An apparatus is provided for supply of the funnels for the user. The apparatus stores extra funnels and toilet rolls. The apparatus has at least one fastening device on its exterior for attaching the apparatus to water tank of the toilet.
A method for directing urine into a toilet from a standing user comprises the step of providing a supply of the flushable funnels. Each of the funnels has an inlet end, an outlet end and a passage between the two ends. The inlet end is adapted to register with outlet of urethra of the user. The outlet end is adapted to direct urine into the toilet. A plurality of flushable paper walls forms a passage between the inlet end and the outlet end. Urine is directed from the standing user into the inlet end, flows through the passage and exits the funnel through the outlet end and flows into the toilet. The funnel is made of a flushable and bio-degradable material configured to retain its substantial strength and shape temporarily when wetted. The method steps further comprises removing a funnel from the supply of funnels and suspending the funnel relative to the toilet to provide a path for urine from the standing user into the toilet. Then, urine is directed into the suspended funnel to channel the urine into the toilet. The suspended funnel is then released allowing the funnel to drop into the toilet. Flushing the toilet flushes away the dropped funnel. The funnel may be suspended by a tail portion. The funnel may be suspended by a protrusion that forms a lip extending outwardly and around one of the ends of the funnel. The funnel may be suspended by deploying a movable arm. The movable arm will be returned to a stored position after urination.
Thus, the flushable funnel is a novel, unique and very useful device to prevent urine-splatter on and around a toilet. The device is very affordable compared to alternatives like traditional urinals.
The splatter-preventing flushable urinary device alleviates deficiencies of prior arts and provides further benefits including:

- (a) Prevents urine splatter on and around a toilet.
- (b) Keeps the toilet more clean and hygienic.
- (c) Reduces splashing and embarrassing sounds of urine stream.
- (d) Easy to place and easy to use.
- (e) Requires no additional floor space or plumbing work.
- (f) Reduces use of toxic cleaning chemicals.

DETAILED DESCRIPTION OF EMBODIMENTS

The embodiments may be best described by reference to the drawings. Disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. As disclosed in Applicant's prior application Ser. No. 13/368,208, the flushable funnel may be of different suitable shapes and sizes including, but not limited to, square, round, oval, rectangular, or polygon. The funnel may be made in suitable lengths to suit different sizes of toilets. The different suitable shapes and sizes signifies that the walls of the flushable funnel may be flat, curved, tapered upward or tapered downward. The tapered funnels may be stacked in nested stacks. Tubular shaped funnels may be stacked in regular stacks. As illustrated in FIGS. 1 through 5 and 11 are some different shapes and sizes of the flushable funnel. The funnel is comprised of an inlet end, an outlet end and a passage formed by a plurality of flushable paper walls. Additionally, the funnel may have at least one tail adjacent a portion of one of the ends. The tail forms a handle to be held by a user or a funnel dispensing apparatus. The funnel may have more than one tail to form additional handles. The funnel may have a protrusion that forms a lip around the larger end of the funnel to enable the funnel to be held in a place. This place may be a funnel dispensing apparatus or a hand of a user. The funnel is to direct urine into a toilet from a standing user, male or female. The funnel helps prevent urine splatter on and around the toilet by user directed use of the funnel. The user keeps the inlet end of the funnel at the outlet of his or her urethra and the outlet end of the funnel above the middle of the toilet and directs urine into the toilet. After urinating, the user drops the used funnel into the toilet and flushes the toilet. The biodegradable funnel breaks down in the sewer system.
The materials of the flushable funnel may be compounds or papers having a wet strength and temporary water repellency while retaining the property of being flushable. The funnel retains its substantial strength and shape temporarily when wetted. Such papers can be manufactured. For example, an invention in U.S. Pat. No. 4,920,171 presented a paper product suitable for applications requiring wet strength and water repellency while retaining the property of being flushable. The invention in U.S. Pat. No. 4,920,171 may be used in its entirety for manufacturing the flushable funnels. The invention in U.S. Pat. No. 4,920,171 is directed to a coating composition for application to a flushable cellulosic based waterleaf sheet to impart transitory water repellency to at least one surface of the sheet. The funnel paper may have temporary wet strength resin, such as melamine formaldehyde, urea formaldehyde, or a neutral cure wet strength material. Furthermore, the funnel may be strong enough to withstand force of a urine stream from a user. The funnel may be moderately slippery so that it may slide out easily from a stack of the funnels placed around a cardboard core. Different methods may be used to manufacture the funnels.
