TRIGGER SPRAY TOOTHBRUSH
FIELD OF INVENTION:
The present invention relates to the field of manually operated trigger mist-spray toothbrushes for dispensing desired liquid solutions from the reservoir within the handle, a device that will incorporate toothbrush, dentifrice, and tongue cleaner in one simple to use instrument, and more particularly to a trigger actuated manual spray pump in a toothbrush with an ergonomic trigger which enables consumers or users to operate for extended periods of time with ease while using.
BACKGROUND OF THE INVENTION:
The oral health and hygiene is the most sought after field all over the world, and almost all communities in the world are desperately looking for a more efficient, convenient, hygienic, and easy to use and carry, self-sanitising, and self-sufficient fountain-toothbrush.
Our mouth attracts thousands of harmful micro-organisms along with the good ones. Almost everyone in the world habitually cleans the teeth and the mouth daily with something and the largest chunk of people still use the traditional toothbrush with toothpaste or toothpowder. Even the toothbrush attracts, colonises and breeds harmful micro-organisms (bacteria, viruses and microbes); and keeping it cleaned or sanitized between the uses, is critical for preventing certain diseases and illness.
Unlike those series of revolutionary inventions in making of fountain pens, many inventions all over the world have been trying to effectively put together the toothbrush and toothpaste (dentifrice), but have not succeeded to attract the market because of some technical snags and flaws. Many abortive attempts in the prior art have been made for making a two-in-one or built-in system in the name of 'fountain toothbrush', 'pen toothbrush' and 'dentifrice dispensing toothbrush',
but hardly any so far has successfully meet the popular demand of the people and the market.
People who travel are often restricted with the amount of items that they can carry with them. Thus, a need exists for a device that will incorporate toothbrush, dentifrice and tongue cleaner that people use for dental hygiene in one simple to use instrument, which in a more hygienic way can easily be transported without occupying a great deal of space.
There are some electric tooth spraying or streaming pump devices without brush for cleaning teeth and mouth, which is expensive, cumbersome and not very effective.
Besides allowing effective and convenient oral hygiene, whether in home or outside, the subject device of the present invention has the following distinguishing characteristics: ease of use, disposable, portable (it can even be stored inside small handbag), elasticity (which allows easy holding even in the absence of a handle), the presence of a capsule (or dispenser) in the handle to distribute the desired liquid.
While some devices in the prior art fulfil their respective, particular objective and requirements, but no patent describe such a toothbrush with a trigger actuated manual pumping system for allowing desired fluid / liquid solution to be pumped independently from within the reservoir in the handle of the toothbrush by a easy, reliable, and simple mechanism.
In this respect, the toothbrush with trigger mist pumping system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of oral application, allowing the desired fluid to be pumped and
sprayed independently through the nozzle drawn from within the body of the toothbrush.
Therefore, it can be appreciated that this new and improved invention of toothbrush is devised and designed with a greater concern to be more cost- effective, simple, hygienic, ergonomic, utility, easy to use and carry, and easy to manufacture, i.e. convenient for industrial design-production-application application with few components/parts. It can effectively and independently spray the desired liquid solutions to the desired place of the teeth or in the mouth from the toothbrush itself. In this regard, the present invention substantially fulfils a variety of concerns and needs.
THE OBJECTS / SUMMARY OF THE INVENTION:
The present invention provides a simpler built-in spray mechanism in the 'Trigger Spray Toothbrush', devised and designed to provide an instant, easy and convenient way for not only preventing any contamination of the bristle sanitised with the routine application of antibacterial/antiviral solution, but to clean the teeth effectively, and still open to additional applications for medicinal, therapeutic and freshening need.
The primary object of the invention is to provide a self-sanitising, trigger actuated mist-pump-spray manual toothbrush, which is contrary to the conventional or traditional toothbrush and toothpaste/toothpowder practise. The toothbrush has a conveniently designed button-trigger-lever mechanism to actuate the manual pump to draw liquid solution from the reservoir in the handle to be used in the brushing operation. The reservoir in a transparent plastic handle portion will allow users to see the remaining amount of liquid solution. The ergonomically designed elongated fat handle of the toothbrush will allow sufficient space within to store required amount of desired liquid solution, and fit comfortably in the hand with better grip and manoeuvrability. It is to make choice for the manufacturer of the
present invention refillable or non-refillable, as both options are given. The airtight plastic cap of the toothbrush-head will prevent any contamination and protect from germs to breed and dirt to accumulate over the bristle and the nozzle.
The disinfecting agent in the liquid solution within the trigger spray toothbrush has the potential to dramatically reduce the chances of re-introducing harmful micro-organisms to the mouth that may otherwise linger on the toothbrush during an illness. During healthy periods, the present invention provides a convenient method for the general improvement of oral hygiene practices. In addition, there may be a reduced risk of cross-infection between a sick family member and those who store their toothbrushes within close proximity of the infected instrument.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
