BACKGROUND OF THE INVENTION
1. Technical Field
This invention relates to oral hygiene products and, more particularly, to a dental floss dispenser with water reservoir for providing users with an easy and convenient means of wetting the floss with fluid disinfectant to render it more comfortable and hygienic for use.
2. Prior Art
Proper hygiene is a key factor in maintaining a healthy and happy existence. Reducing germs and bacteria, hygiene practices are important for making a person feel clean and fresh on a daily basis. Taking a quick shower or enjoying a long, hot soak in the bathtub, are some activities that can cleanse the body and refresh the spirit. In particular, maintaining proper oral hygiene is crucial to ensure overall good health. Although most adults realize the considerable role daily brushing plays in maintaining health, many overlook the importance of using dental floss. Flossing between the teeth after each meal is an absolute must, if one wishes to keep their breath fresh, teeth clean, and gums healthy. Brushing teeth properly and consistently helps to remove most dental plaque; however, brushing alone cannot remove plaque that is located in places that a toothbrush cannot reach, particularly in between teeth. In addition to removing plaque, flossing also helps to dislodge debris that adheres to teeth and gums, and serves to polish the teeth. Most dentists recommend that flossing should take place at least once a day for two to three minutes each time to be most effective.
Unfortunately, flossing the teeth can be a difficult and unsettling task, simply because the rigid, dry floss can cause discomfort when sliding between the teeth and against the gums. As such, many consumers opt to skip this important hygiene procedure, only to be diagnosed with cavities or other forms of tooth decay on their next visit to the dentist office.
Accordingly, a need remains for an apparatus in order to overcome the above-noted shortcomings. The present invention satisfies such a need by providing a dental floss dispenser with fluid reservoir that is convenient and easy to use, is durable yet lightweight in design, is versatile in its applications, and provides an easy and convenient means of wetting the floss with fluid disinfectant to render it more comfortable and hygienic for use.
BRIEF SUMMARY OF THE INVENTION
In view of the foregoing background, it is therefore an object of the present invention to provide an apparatus for promoting dental hygiene. These and other objects, features, and advantages of the invention are provided by a dental floss dispenser.
The dental floss dispenser may include a portable container body preferably having an interior cavity. A non-linear reservoir may be formed inside the interior cavity and situated along an interior perimeter of the container body. A spool may be rotatably coupled to the container body and seated inside the interior cavity. A predetermined volume of fluid may be housed inside the reservoir. A predetermined quantity of floss may further be releasably wound about the spool. A leading end of the floss may be channeled through the reservoir and thereby soaked in the fluid prior to exiting the container body. The spool may remain isolated from the reservoir such that a remaining portion of the floss is maintained at a dry state. Such an arrangement provides the unexpected and unpredictable advantage of wetting and softening the dental floss as it is being pulled out from the dental floss dispenser. In this way, the dental floss 11 may be wetted with the fluid 24 and made soft so that it can be easily inserted between a user's teeth.
The dental floss dispenser may further include a lid pivotally coupled to the container body. A floss guide may be located inside the container body and situated above the reservoir. A floss cutter may further be connected to the floss guide. The floss guide and the floss cutter may further be situated exterior of the interior cavity for directing the floss away from the container body. Such an arrangement provides the unexpected and unpredictable advantage of guiding the dental floss away from the portable container body and thereafter, allowing a user to cut a desired length for use easily without having to utilize another cutting appliance.
The leading end of the floss may travel along a first passageway located interior of the reservoir before exiting the container body. The first passageway may include first, second and third linear segments conjoined at an end-to-end pattern and extending within the reservoir respectively. The leading end of the floss may further travel along a second passageway located exterior of the reservoir. The second passageway may include a fourth linear segment extending away from the third linear segment and the reservoir respectively. The fourth linear segment may be channeled through the floss guide along a travel path registered parallel to the second linear segment. In this way, the leading end of the floss may be maintained in a wet environment within the fluid while traveling along the first, second and third linear segments; and be maintained in a dry environment while traveling along the fourth linear segment. Such an arrangement provides the unexpected and unpredictable advantage of providing an unimpeded path for the dental floss and to be automatically wetted prior to exiting the dental floss dispenser.
The fluid may include at least two disinfecting agents selected from a group including mouthwash, water, fluoride and any combination thereof. Such an arrangement provides the unexpected and unpredictable advantage of providing a dual use for the dental floss including disengaging leftover food and debris stuck between a user's teeth and disinfecting a user's teeth and gums simultaneously.
The reservoir may include an access port for depositing and draining the fluid from the reservoir while the leading end of the floss remains housed inside the reservoir. An inlet port may be formed at a first top end of the cavity and disposed at a beginning of the first linear segment. An outlet port may be formed at a second top end of the cavity and disposed at an end of the third linear segment. In this way, the leading end of the floss may ingress the reservoir via the inlet port and thereafter may egress the reservoir via the outlet port prior to reaching the floss guide. Such an arrangement provides the unexpected and unpredictable advantage of holding the fluid in the reservoir as well as providing a channel for the dental floss to be wetted within a water tight assembly.
The reservoir may further include a first guide pulley rotatably situated at a junction of the first and second linear segments and a second guide pulley rotatably situated at a junction of the second and third linear segments respectively. In this way, each of the first and second guide pulleys may maintain continuous contact with the leading end of the floss and thereby continuously direct the leading end of the floss along the first, second and third linear segments inside the reservoir respectively. Such an arrangement provides the unexpected and unpredictable advantage of ensuring that the dental floss may be smoothly extracted from the container body without being entangled in any way.
The first and third linear segments may further have coextensive longitudinal lengths and are registered parallel to each other, while the second and fourth linear segments have coextensive longitudinal lengths and are registered parallel to each other. Such an arrangement provides the unexpected and unpredictable advantage of providing a box-shaped and compact enclosure whereby a user may rest the apparatus upright on a side of the container body corresponding to the second segment of the reservoir. In this way, the user may make doubly sure that the fluid contained within the reservoir may not egress from the inlet and outlet ports of the container cavity.
The invention may include a method of utilizing a dental floss dispenser for promoting dental hygiene. Such a method may include the chronological steps of: providing a portable container body preferably having an interior cavity formed therein; providing a non-linear reservoir formed inside the interior cavity and situated along an interior perimeter thereof; providing and seating a spool inside the interior cavity by rotatably coupling the spool to the container body; providing and housing a predetermined volume of fluid inside the reservoir; providing and releasably winding a predetermined quantity of floss about the spool; providing for soaking a leading end of the floss in the fluid prior to exiting the container body by channeling the leading end of the floss through the reservoir; and providing for maintaining a remaining portion of the floss at a dry state by isolating the spool from the reservoir. There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.

The below disclosed subject matter is to be considered illustrative, and not restrictive, and the appended claims are intended to cover all such modifications, enhancements, and other embodiments which fall within the true scope of the present invention. Thus, to the maximum extent allowed by law, the scope of the present invention is to be determined by the broadest permissible interpretation of the following claims and their equivalents, and shall not be restricted or limited by the foregoing detailed description.
The apparatus of this invention is referred to generally in FIGS. 1-4 by the reference numeral 10 and is intended to provide a dental floss dispenser. It should be understood that the dental dispenser 10 may be used to provide a dental floss and many different types of stringed implements that is soft, wet and hygienic for use.
Referring generally to FIGS. 1-4, the dental floss dispenser 10 may include a portable container body 20 preferably having an interior cavity 21. A non-linear reservoir 22 may be formed inside the interior cavity 21 and situated along an interior perimeter of the container body 20. A spool 23 may be rotatably coupled to the container body 20 and seated inside the interior cavity 21. A predetermined volume of fluid 24 may be housed inside the reservoir 22. A predetermined quantity of floss 11 may further be releasably wound about the spool 23. In this manner, a leading end of the floss 11 may be channeled through the reservoir 22 and thereby soaked in the fluid 24 prior to exiting the container body 20. Advantageously, the spool 23 remains isolated from the reservoir 22 such that a remaining portion of the floss 11 is maintained at a dry state. Such an arrangement provides the unexpected and unpredictable advantage of wetting and softening the dental floss 11 as it is being pulled out from the apparatus 10. In this way, the dental floss 11 may be wetted with the fluid 24 and made soft so that it can be easily inserted between a user's teeth.
Referring again to FIGS. 1-4, the dental floss dispenser 10 may further include a lid 26 pivotally coupled to the container body 20. A floss guide 27 may be located inside the container body 20 and situated above the reservoir 22. A floss cutter 28 may be connected to the floss guide 27. The floss guide 27 and the floss cutter 28 may be situated exterior of the interior cavity 21 for directing the floss 11 away from the container body 20. Such an arrangement provides the unexpected and unpredictable advantage of guiding the dental floss 11 away from the portable container body 20 and thereafter, allowing a user to cut a desired length after the floss 11 is soaked.
As perhaps best shown in FIG. 4, the leading end of the floss 11 may travel along a first passageway 29 located interior of the reservoir 22 before exiting the container body 20. The first passageway 29 may include a first linear segment 30, a second linear segment 31, and third linear segment 32 conjoined at an end-to-end pattern and extending within the reservoir 22, respectively. The leading end of the floss 11 may further travel along a second passageway 33 located exterior of the reservoir 22. The second passageway 33 may include a fourth linear segment 34 extending away from the third linear segment 32 and the reservoir 22, respectively. The fourth linear segment 34 may be channeled through the floss guide 27 along a travel path registered parallel to the second linear segment 31. In this way, the leading end of the floss 11 is advantageously maintained in a wet environment within fluid 24 while traveling along the first, second and third linear segments 30, 31, 32, respectively, and maintained in a dry environment while traveling along the fourth linear segment 34. Such an arrangement provides the unexpected and unpredictable advantage of providing an unimpeded wet passageway 29 for dental floss 11 wherein excess fluid 24 is wiped from floss 11 along the dry passageway 33 prior to exiting the apparatus 10 so that fluid residue is not deposited exterior of the container body 20
Referring to FIG. 4 again, the fluid 24 may include at least two disinfecting agents selected from a group including mouthwash, water, fluoride and any combination thereof. Such an arrangement provides the unexpected and unpredictable advantage of soaking floss 11 in a disinfectant fluid prior to expelling floss 11 from container body 20.
Referring to FIGS. 2-4, the reservoir 22 may include an access port 35 for depositing and draining the fluid 24 from the reservoir 22 while the leading end of the floss 11 remains housed inside the reservoir 22. An inlet port 36 may be formed at a first top end of the cavity 21 and disposed at a beginning of the first linear segment 30. An outlet port 37 may be formed at a second top end of the cavity 21 and disposed at an end of the third linear segment 32. In this manner, the leading end of floss 11 ingresses reservoir 22 via inlet port 36 and thereafter egresses reservoir 22 via outlet port 37 prior to reaching floss guide 27. Such an arrangement provides the unexpected and unpredictable advantage of holding the fluid 24 in the reservoir 22 as well as providing a channel for the dental floss 11 to be wetted prior to being cut by floss cutter 28.
Referring to FIGS. 1, 2 and 4, the reservoir 22 may further include a first guide pulley 38 rotatably situated at a junction of the first and second linear segments 30, 31 and a second guide pulley 39 rotatably situated at a junction of the second and third linear segments 31, 32, respectively. In this way, each of the first and second guide pulleys 38, 39 maintain continuous contact with the leading end of floss 11 and thereby continuously direct the leading end of the floss 11 along the first, second and third linear segments 30, 31, 32 inside reservoir 22, respectively. Such an arrangement provides the unexpected and unpredictable advantage of ensuring that the dental floss 11 is smoothly extracted from the container body 20 without being entangled or rubbed against an interior wall of reservoir 22 during the unwinding process.
Referring again to FIG. 4, the first and third linear segments 30, 32 may further have coextensive longitudinal lengths and are registered parallel to each other, while the second and fourth linear segments 31, 34 have coextensive longitudinal lengths and are registered parallel to each other. Such an arrangement provides the unexpected and unpredictable advantage of providing a box-shaped and compact enclosure whereby a user may rest the apparatus 10 upright on a side of the container body 20 corresponding to the second segment 31 of the reservoir 22. In this way, the fluid 24 remains contained within the reservoir 22 and will not prematurely leak out form inlet and outlet ports 36, 37 of the container cavity 21.
The present invention may further include a method of utilizing a dental floss dispenser 10 for promoting dental hygiene. Such a method may include the chronological steps of: providing a portable container body 20 preferably having an interior cavity 21 formed therein; providing a non-linear reservoir 22 formed inside the interior cavity 21 and situated along an interior perimeter thereof; providing and seating a spool 23 inside the interior cavity 21 by rotatably coupling the spool 23 to the container body 20; providing and housing a predetermined volume of fluid 24 inside the reservoir 22.
The method may further include the chronological steps of: providing and releasably winding a predetermined quantity of floss 11 about the spool 23; soaking a leading end of the floss 11 in fluid 24 prior to exiting the container body 20 by channeling the leading end of the floss 11 through the reservoir 22; and maintaining a remaining portion of the floss 11 at a dry state by isolating the spool 23 from the reservoir 22.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The combination of such claimed elements provides an unpredictable and unexpected benefit of wetting a dental floss hygienically while removing it from the dental floss dispenser, which solves the problem of having to position the floss under a bottle of disinfectant or running tap to wet and soften the floss.
While the invention has been described with respect to a certain specific embodiment, it will be appreciated that many modifications and changes may be made by those skilled in the art without departing from the spirit of the invention. It is intended, therefore, by the appended claims to cover all such modifications and changes as fall within the true spirit and scope of the invention.
In particular, with respect to the above description, it is to be realized that the optimum dimensional relationships for the parts of the present invention may include variations in size, materials, shape, form, function and manner of operation. The assembly and use of the present invention are deemed readily apparent and obvious to one skilled in the art.
