No. 5,346,324 entitled “Dentifrice Dispensing Toothbrush with Replaceable Cartridge,” United States Patent Application Publication Number 2010/0284726 entitled “Liquid Dentifrice Dispensing Toothbrush,” International Patent Application Publication Number WO 1991/007143 entitled “Dental Floss Applicators,” and Korean Patent Application Publication Number 10-1268233 entitled “Oral Care Implement Having Fluid Delivery System”—all of which are hereby incorporated herein by reference in their entirety including all references cited therein.
U.S. Pat. No. 9,930,957 (hereinafter the '957 patent) appears to disclose various dental devices that are available for cleaning the mouth, gums and teeth. However, these dental devices may also cause abrasions to the mouth and/or gums. The dental devices include a reservoir for storing a liquid and for application of the liquid to the mouth, teeth and/or gums. The liquid may be an antibacterial liquid, such as a hydrogen peroxide solution, a salt solution or a teeth whitening solution or gel, for example. An antibacterial liquid may be applied to prevent infection of the abrasions. The reservoir may be in a hollow handle of the dental device, such that the liquid may be easily pumped or moved from the reservoir to an outlet at the functional end that may cause the abrasions. As is shown in
U.S. Pat. No. 8,668,493 appears to disclose an interdental cleaner that includes a source of liquid and a control system including a manual pump, for moving a selected amount of liquid, suitable for a single use, into a liquid pathway and there to a mixing chamber. A source of pressurized gas, such as a CO2 cartridge, is used to preload a selected amount of gas into a gas chamber. The control system includes a spring-loaded button, which upon operation results in the manual pump being operated, forcing the selected amount of liquid into the mixing chamber, and then upon release, permits the pressurized gas in the gas chamber to enter the mixing chamber, breaking up the liquid therein into droplets and a liquid stream, and propelling the resulting liquid out of a nozzle portion of the cleaner into the interproximal area of the teeth.
U.S. Pat. No. 6,957,958 appears to disclose an applicator having an applicator end portion and a material end portion. The material end portion forms a container holding a material to be applied with the applicator end portion. Upon separating the material end portion from the handle portion of the applicator, a container is formed which is used to dip the applicator into the end portion of the applicator. The present invention is particularly applicable to the dispensing of medicaments, and in particular, dental materials. A single dose of material is integrally formed within the applicator and sealed until ready for use.
U.S. Pat. No. 5,908,257 appears to disclose a toothbrush that is adapted to contain a significant quantity of toothpaste therein and to dispense the toothpaste onto the toothbrush bristles. The toothbrush generally comprises a hollow handle having a brush head formed integrally on its top end, a disposable toothpaste containing cartridge supported within its interior, and a piston mechanism threadably attached to its bottom end. The piston mechanism is adapted to force the toothpaste out of the handle into a conduit formed through the brush head. The conduit leads from the interior of the handle to a plurality of outlet holes disposed below resilient valves in a rubber gasket layer which supports the bristles. The valves allow toothpaste to flow from the conduit onto the bristles of the toothpaste while preventing water or other fluids from flowing into the conduit to contaminate the toothpaste supply.
U.S. Pat. No. 5,906,213 appears to disclose a dental cleaning tool that has a handle, a base, a floss stem, and a supply of dental floss. The dental floss is contained within the base and a supply of fluid is contained within the handle. The base and the handle removably engage each other, frictionally clamping one end of the dental floss therebetween. Both the fluid and the other end of the dental floss exit through a fluid ejection conduit of the base. The floss is removably engaged to a floss locking tip near the terminal end of the floss stem, allowing the user to utilize the dental floss to clean his teeth. While flossing his teeth, the user can squeeze the handle and spray fluid, such as mouth wash, down the length of the dental floss and into his mouth.
U.S. Pat. No. 5,365,956 appears to disclose a toothbrush having a spool of floss that is stored within the handle and a floss holding frame for holding a portion of the floss in a taut condition for use thereof. The toothbrush includes a handle which terminates in a floss holding frame across which floss from the spool may be extended and held tight. The floss spool and the floss holding frame are longitudinally arranged such that a protective cover may be placed thereover.
U.S. Pat. No. 5,346,324 appears to disclose a dentifrice dispensing toothbrush which utilizes a compressible elastic button to pump a controlled quantity of dentifrice material from a replaceable cartridge to the brush head. The toothbrush locks itself to prevent further pumping of dentifrice material when its replaceable cartridge is nearly empty. The self-locking mechanism eliminates the formation of voids in the dentifrice material and consequent pump failure when the spent cartridge is replaced. In one embodiment, a cover is provided which protects the brush head, bristles, pumping mechanism and other parts of the toothbrush. The cover also seals the conduit which supplies dentifrice material to the brush head to prevent it from becoming clogged with dried dentifrice material during periods of non-use and to prevent accidental compression of the button. The compressible elastic button is part of a pump assembly which also includes a pump chamber, a partition which divides the pump chamber into an intake compartment and a discharge compartment, a one way check valve for an opening in the base of the pump chamber to control the flow of dentifrice material from the cartridge to the pump chamber and an opening in the partition between the intake and discharge compartments. A plug is attached to the top of a follower disc which is positioned in the cartridge. When the cartridge is nearly depleted, the plug locks the toothbrush by blocking the dispensing movement of the dentifrice material.
United States Patent Application Publication Number 2010/0284726 appears to disclose a dentifrice dispensing toothbrush for applying a predetermined measured amount of liquid dentifrice from a reservoir of liquid dentifrice into the toothbrush bristles by means of an in integral pump. Liquid dentifrice may be refilled using the handle portion of the toothbrush.
International Patent Application Publication Number WO 1991/007143 appears to disclose a dental floss applicator that comprises a casing to hold a container of dental floss and a pressure activated container of flowable medication or freshness agent. The casing is in two parts, a body portion and a sleeve, the sleeve being slidable relative to the body portion. The body portion holds the containers and has a neck and head portion. The sleeve is relatively slidable towards the head to cause pressure activation and discharge of a controlled small metered dose of agent from outlets in the head into floss carried by pronged arms on the head. Floss is drawn from the container, along the neck to the head then back along the neck to a securing means on the sleeve so that when the sleeve is drawn away from the head a fresh length of floss is drawn onto the head to lie between pronged arms. The lengths of floss upstream and downstream of the head pass under a hinged clamp which tensions the floss or releases the floss to enable the sleeve to draw in a fresh length of floss.
Korean Patent Application Publication Number 10-1268233 appears to disclose an oral care implement that includes a head having a tooth cleaning element on one surface and a reservoir holding at least one active agent. The capillary channel extends through at least a portion of the oral care implement to dispense the active agent(s) to one or more outlets. According to one feature, a vibration generating device is provided that vibrates at least a portion of the instrument to enhance the function of the tooth cleaning element and the distribution of the active agent through capillary action. Various active agents may be administered for treatment, hygiene, and/or other benefits such as fresh breath and teeth whitening or the creation of hot and cold and bitterness.
