Oral hygiene implement and method of use

Abstract

Oral hygiene implement including a handle, a first head mounted to the first end of the handle, a second head mounted to the second end of the handle, including a plurality of cleaning elements extending from the first head and the second head wherein the cleaning elements can exhibit releasable dentifrice retained in the cleaning elements.

Description

FIELD OF THE INVENTION[0001]The present invention generally relates to the field of oral hygiene for humans and animals. More specifically, the present invention relates to a device and method of use of same for facilitating the cleansing of the areas of the mouth without damaging tooth enamel and creating irritation to the gum or other portions of the mouth area.BACKGROUND OF THE INVENTION[0002]Oral hygiene is the practice of keeping the oral cavity clean to prevent dental concerns and limit the presence of bacteria in the mouth region resulting in bad breath. The use of oral care implements, such as toothbrushes, soft tissue cleaner devices, and combination devices of similar nature, is highly recommended as severe gum disease results in a substantial percentage of adult tooth loss. In addition, tooth decay is the most common global disease resulting from the generation of cavities inside pits and fissures on chewing surfaces where brushing cannot reach trapped and remaining food ...

AI Technical Summary

Benefits of technology

[0032]In short, in a primary embodiment, provided is a novel toothbrush with dentifrice feed system exhibiting ease of use and improved oral cleaning capability. The toothbrush, made of a common plastic material or the like, includes an ergonomic handle and grip mechanism for comfort of use and having a first head of ergonomic parallelogram shape positioned at a first end of the handle and a second head of ergonomic parallelogram shape positioned at a second end of the handle. The first head and second head employ a plurality of bristles of various shapes, lengths, strengths, and arrangements designed for particular cleaning aspects such as tooth cleaning, roof of mouth cleaning, tongue scrapping, plaque removal, gum massaging, etc. for maximum cleaning efficacy and various applications. Each head further including a plurality of grooves and channels to effectively distributing applied dentifrices during use of the oral care implement. Each head further including one or more reservoirs for maintaining a dentifrice pod or packet sealed in a soluble material such as a film. Such packets can contain any of a plurality of cleaning agents, including but not limited to toothpastes for improved tooth cleaning and mouthwash for killing germs in hard to reach places, freshening breath, loosening food caught between teeth, and fighting cavities.

Problems solved by technology

In addition, tooth decay is the most common global disease resulting from the generation of cavities inside pits and fissures on chewing surfaces where brushing cannot reach trapped and remaining food and saliva or fluoride have no access to neutralize acid and re-mineralize de-mineralized teeth.

Plaque accumulation causes the gingiva to become irritated and inflamed, resulting in the eventual loss of the connective tissue fibers that attach the gums to the teeth and bone that surrounds the tooth (i.e., periodontitis).

Importantly, the design of the toothbrush heads have limited ability to retain dentifrice, mouthwashes, or other oral hygiene pastes and gels for the application on a tooth or soft tissue regions of the mouth.

Specifically, Lafortune claims that while certain toothbrushes in the art employ a brush and dentifrice disposed therein thereby eliminating the need for both a toothbrush and a toothpaste tube such toothbrushes have been intended for long-time use and as a result “complex and expensive solutions” to the refilling of the handles with toothpaste have been implemented.

“Also, in the prior toothbrushes, valves have been used which prevent the expulsion and waste of toothpaste and the contact of the toothpaste with air which would result in caking” and “[s]uch valves add significantly to the cost of the toothbrushes.”

While the Lafortune disclosure is clearly an improvement over the existing art, it is limited to its short-term use.

Further, Lafortune is only useful for the application of toothpaste and does not employ a means to utilize additional oral hygiene products such as mouthwash or the like.

Another possibility is the antibacterial effect even without tooth paste.” While the insertion of a “polishing block” is clearly the novelty of the Durana disclosure, clearly such use of a soluble “polishing block” can not be replenished once the block is depleted after one or more periods of use.

While clearly an improvement over the existing art, Frazell fails to explore and implement a system comprising a dual-head design and means for providing a single compact unit for the dispersion of multiple oral hygiene solutions.

Andersen claims that the device exhibits several advantages over the existing art as “it eliminates multiple users of the common tube of toothpaste, providing separate individual doses of toothpaste to each person” and it aids in the decrease of “the spread of disease between family members and toothpaste users.” While the Andersen disclosure is likely an improvement over the then-existing art as it potentially exhibits its intended objective, the Andersen disclosure fails to provide a system comprising a dual-head design and means for providing a single unit for the dispersion of multiple oral hygiene solutions.

Further, Andersen fails to provide a device capable of providing multiple layers of oral hygiene cleaning such as tongue cleansing or improved bristle placement.

However, it will be readily apparent to one of ordinary skill in the art that Clark fails to disclose a dual-head design and means for providing a single unit for the dispersion of multiple oral hygiene solutions.

Further, Clark fails to provide a device capable of providing multiple layers of oral hygiene cleaning such as tongue cleansing or improved bristle placement.

Clearly, the Wong disclosure includes more than one layer of oral hygiene cleaning (i.e., a toothbrush and an interdental brush designed to “clean areas of the mouth inaccessible or awkward to reach with the main brush”), however, Wong fails to provide a device capable of dispersing toothpaste or similar oral hygiene solutions.

Like several of the earlier disclosures, Wenzler fails to provide a device capable of dispersing toothpaste or similar oral hygiene solutions in conjunction with the multiple oral cleansing devices.

Further, Vazquez et al. fails to provide multiple cleaning implements for the application of more than one dentifrices such as toothpaste accompanied by a whitening gel or a mouthwash.

Finally, Vazquez et al. fails to provide a means for integrating common dental floss or the like in a portable form in one integral unit.

However, Robinson et al. still fails to provide multitude heads to allow for the application of discreet application of a plurality of dentifrice or related agents.

Further, Robinson et al; fails to provide a plurality of cleaning implements to allow for tongue cleaning, roof cleaning, or other regions of the oral cavity, including hard to access regions.

In addition, Robinson et al. fails to provide a means for the release of dental floss in one integral compact unit which is highly useful for personal at home use or use during travel.

Specifically, none of the aforementioned references provide for a hygienic and compact dual head toothbrush capable of adequately dispersing various oral hygiene solutions, pastes, and / or gels designed for single or multi-use which exhibits an ease of manufacture and limited complexity of use.
