Overview
An aspect of some embodiments of the current invention relates to a composition for use in reducing splashing on excretion into a toilet is disclosed and described. Optionally, the composition may reduce noise and/or odor on excretion into a toilet. Optionally, the composition may disinfect a toilet after use. Optionally, the composition may remove and/or prevent accumulation of dirt on the inner walls of a toilet.
There is a need for an easily portable composition which prevents splashing for use in the home and in particular in public restrooms. Optionally, the composition may also reduce unpleasant noise while providing a pleasant scent, disinfection and cleaning of the toilet.
According to some embodiments, the composition may react with water, e.g., in the toilet bowl, to produce a foam. Optionally, the composition may include one or more carbon dioxide sources, one or more acids and a one or more surfactants. Optionally, the composition may include one or more additional excipient. Optionally, the composition may include one or more disintegrants.
According to some embodiments, the composition may be in the form of a tablet, capsule, wafer, sheet, powder, granules, crystals, etc. Optionally, the composition may float on or near the surface of the water-air interface. Optionally, the composition may rapidly dissolve and/or disintegrate in the water. Optionally, the composition may sink slowly. Optionally, the composition may be easily portable, e.g., easily transported and/or concealed in a pocket and/or a handbag and/or backpack and/or briefcase, etc. Unless otherwise stated, the word tablet is used herein in a general sense as any solid form of a chemical composition. For example, a tablet may be made up of compressed powder. Optionally a tablet may have any shape. Optionally, a tablet may have a homogenous and/or an heterogenous composition on different scales.
According to some embodiments, the foam generated on reaction with the toilet water may be a thick layer of carbon dioxide bubbles. Optionally, the composition may react rapidly with the water in the toilet bowl to produce a thick layer of foam. Optionally, the foam may allow matter to pass through it. Optionally, the foam may slow the passage of matter dropped onto it. Optionally, the foam may catch matter dropped onto it. Optionally the composition may change characteristics of the water (e.g., surface tension, density, viscosity). Optionally, the foam may dissipate after a period of time. Optionally, the foam may disintegrate after a period of time. Optionally, the foam and the waste may be flushed away. Optionally, the composition and/or the foam may not produce a blockage in the drain and/or drainage system. Optionally, the composition and/or the foam may be biodegradable.
According to some embodiments, the composition may include a pleasant scent which may be released on use. Optionally, the composition may be used to remove and/or prevent accumulation of dirt on the walls of the toilet. Optionally the composition may contain a disinfectant. For example, the composition may be dropped into a toilet, foam is generated upon contact with water, the foam reduces noise, splashing and/or unpleasant odors produced upon excretion into the toilet.
In some embodiments, the composition attempts to provide a solution to a widespread, but sometimes unspoken about problem, that might affect many people. Preventing the splashing of the water in the toilet on the falling may cause people discomfort, disgust and/or disease when this water splashes onto them or near to them.
In some embodiments, the splash effect can occur as a result of an object, like a rock for example, falling down into the water, the pressure of the object pushing into the water pushing the water around it in the upward position, resulting in a splash upwards. Some embodiments of the invention attempt to change how the pressure is applied to the water from the falling object e.g., excrement and/or other substances. This problem may be a worldwide problem, which may not have a widely used industrial solution, in the public bathrooms of North America, Europe, and other places. In parts of North America, the problem can be even more noticed because water level in the toilet can reach to ¾ of the height of the toilet bowl. In such a case, the splash can be relatively large, in this somewhat large amount of water, and can greatly discomfort the toilet user and/or a person sitting near the public and/or private toilet. Sometimes people, in attempt to prevent such a splash, before excreting, place in the toilet bowl substantial amounts of toilet paper and/or other substances which may result in clogging of the toilet system. Sometimes there can be multiple people in a short period of time attempting to put toilet paper or another substance to prevent the splash which can result in even more clogging. In addition, this practice can result in excessive use and/or waste of toilet paper and water, through multiple flushes to push the waste down the drain. Also, the splashing may result in noises which may further discomfort and/or embarrass the user in some public or private bathrooms.
In some embodiments, an additional problem that can occur: there could be bathrooms that require cleaning multiple times per day, and when not cleaned germs and/or potentially unhygienic and/or possibly harmful and/or contagious and/or unhealthy and/or unpleasant entities can build up in the toilet. As a result, of an unhygienic bathroom and/or toilet people may refrain from entering and/or may cause themselves damage by preventing themselves from excreting.
There may be a perceived need for a simple, light, not bulky, and inexpensive, product, which does not require extensive operation and extensive time, that may prevent unwanted actions, that will help maintain healthy and comfortable life. In some embodiments, the composition may advantageously preserve hygiene. In some embodiments, the composition may be suitable for any type of toilet. According to some embodiments, the composition may be used to sanitize the toilet and/or the water therein. According to some embodiments, the composition may require no extensive operation and/or does not require physical contact of the user with the toilet bowl and/or the water therein.

While the invention has been described in its preferred form or embodiment with some degree of particularity, it is understood that this description has been given only by way of example and that numerous changes in the details of construction, fabrication, and use, including the combination and arrangement of parts, may be made without departing from the spirit and scope of the invention.
Some embodiments, the composition may solve some or all the problems listed above, under certain conditions. For example, the composition in the form of a tablet may be thrown into the water of the toilet. Optionally, contact with the water, under the right conditions, may cause the tablet to expand rapidly, for example within seconds. Optionally, the tablet may expand like a flower, at the air-water interface, or causing it to touch and/or grasp the walls and/or of the bottom of the toilet bowl.
In some embodiments, the composition may have one or more advantages. For example, prevention of splashing water onto the person sitting on the toilet.
In some embodiments, the composition may include a sheet of paper which may be strong enough to not dissolve immediately in the water of the toilet in order to provide the desired effect, but may also disintegrate in water and therefore may not cause to problems in the pipes of the toilet. In some embodiments. the composition may not contain oils that are used in various wipes to make them softer to the skin, which may cause clogging of the pipes.
In some embodiments, on contact with the water the composition expands to a sheet and/or curls upward, for example at the outer edges. The sheet may optionally continue to expand until it reaches the walls of the toilet bowl. The upward curled edges of the sheet may optionally protect the walls of the toilet from becoming soiled. Optionally, there may be different sized compositions and/or tablets. For example, a larger composition may be configured to spread over surfaces of larger toilets. Optionally, the sheet contacts the inner walls of the toilet. In some embodiments, as the edges of the composition reach the walls of the toilet, they may continue to expand upward along the walls the toilet. For example, this may protect the walls of the toilet from becoming soiled. Optionally, there may be different sized composition and/or tablets. For example, a larger composition may be configured to spread over surfaces of larger toilets.
In some embodiments, the composition may be to remove foul odors and/or provide good smells. For example, on contact of the composition with the toilet water it may release fragrant substances, that provide a good scent. There are many compositions for the purpose of providing good scent. Among them are: air fresher, to provide a good scent after the use of the bathroom, or devices which are built onto or hanging from the toilet which drop liquid and spread a good scent at the time of the flushing the water. In some embodiments, the composition may provide a good scent even before the flushing of the toilet, and/or even before the act of excreting.
In some embodiments, the composition may prevent the buildup of foul odors over time from excrement and/or other filth. Generally, most of the excrement and filth in the toilet centralizes in the bottom of the toilet bowl, however according to some embodiments. the composition may reduce and/or prevent the buildup, allowing it to easily be entirely flushed away with the composition after use. Optionally, the composition may shield the bottom of the toilet from sticking excrement and/or the material of the composition which the excrement is on, itself gets easily flushed and/or draws the excrement down the drain. In some embodiments, this may reduce the amount of constant cleaning required in some bathrooms and/or could reduce the buildup of germs. In some embodiments, the composition may contain antibacterial substances, as is known that excrement contains many germs. There are toilets which might have various wedges, nooks and/or crannies in the toilet bowl in which filth gets stuck a can build up and even be hard to clean. In some embodiments, the composition may prevent filth from getting caught in wedges, nooks and/or crannies in the toilet bowl. For example, the filth may be easily flushed away along with the composition after use. In addition, in some embodiments, the composition may dampen or remove the noise of excrement falling into the water. This is a problem which may yet not have an industrial solution which is widespread. In some embodiments, the composition may be small and/or compact enabling it to not take up much space. In some embodiments, the composition may be easily portable. In some embodiments, the composition may be packaged with illustrated pictures for children which may encourage children to also use the composition and even encourage them to potty train and/or move from a potty to use a full toilet.
List of some aspects of some advantages of composition according to some embodiments follow:
In some embodiments, the composition may be eco-friendly, e.g., it may be biodegradable, break up in water and/or may not cause clogging. In some embodiments, the composition may be sufficiently sturdy to withstand some time in water to fulfill its purpose and/or expands nearly instantaneously, (e.g., in seconds), when touched with the water of the toilet. In some embodiments, the composition may be compact, portable, possible to be in every bathroom as is toilet paper, both public and private bathrooms and/or encourages children to potty train.
Reference is now made to the figures.
Optionally, the foam may be thick enough to catch the fecal matter. Optionally, the foam generated on reaction of the composition with the toilet water may be a thick layer of bubbles. Optionally, the thickness of the foam layer may be between about 0.25 cm to about 15 cm, between about 0.5 cm to about 12.5 cm, between about 1 cm to about 10 cm, or between about 2 cm to about 7.5 cm.
Optionally, the time to ¾ of maximum foam volume may be less than 5 s, 10 s, less than 20 s, less than 30 s, less than 40 s, less than 50 s, less than 1 min, less than 1.5 mins, less than 2 mins, less than 2.5 mins, less than 3 mins, less than 3.5 mins, less than 4 mins, less than 4.5 mins, or less than 5 mins.
Optionally, the foam may absorb and/or prevent the water from an upward splash from rising above the upper surface of the foam.
Optionally, the composition may comprise multiple portions of the composition. Optionally, some of the portions of the composition may be configured to disintegrate and/or dissolve and/or react slower than others. Optionally, this may ensure continuous production of foam over several minutes. Optionally, this may provide waves of foam which may replace areas of foam as it is depleted.
According to some embodiments, the composition should not sink into the toilet trap and/or drain. Optionally, the buoyancy of the composition may be affected by its shape and/or surface features.
According to some embodiments, the composition may be in the form of a capsule, ball, tablet, sachet, coated sachet, granules, wafer, sheet, powder, granules, crystals, pellets, beads, pods, disk, donut (disk with a hole), horseshoe shaped 604, interlocking shapes 606 and 608, and/or a combination thereof. Optionally, the composition may be configured to provide a large surface area. Optionally, the composition may include surface features such as folds, indentations, channels, cut-outs, bubbles, hollows, etc. Optionally, the composition may have a large surface area.
