ABSTRACT:
TECHNICAL FIELD
The present invention relates to toothbrushes with toothpaste delivery systems and more particularly to a toothbrush with toothpaste feed system that includes a toothpaste cartridge feed handle, a hollow brush head, a resilient hinged neck structure connected between the toothpaste cartridge feed handle and the hollow brush head and providing a neck toothpaste passageway between a toothpaste feed end of a toothpaste cartridge cavity within toothpaste cartridge feed handle and a brush head toothpaste passageway formed within hollow brush head, and an accordion fold toothpaste filled cartridge with a rupturable perforated foil end that is sized to fit into the toothpaste cartridge cavity with the rupturable perforated foil end positioned within toothpaste feed end of toothpaste cartridge cavity; toothpaste cartridge feed handle having a rotatable cap and cartridge compressing slide bar that are movable to allow for insertion of the accordion fold toothpaste filled cartridge into the a toothpaste cartridge cavity through a hinged opening provided between the neck of the brush head and the toothpaste cartridge feed handle; the cartridge compressing slide bar being slidable such that the accordion fold toothpaste filled cartridge is compressed sufficiently to rupture the rupturable foil end and force toothpaste through the neck toothpaste passageway and the brush head toothpaste passageway and out onto the brush bristles through a number of toothpaste dispensing openings formed through the exterior of the hollow brush head and positioned adjacent to the bristle bottoms of the brush bristles; the hollow brush head further including a flip open back cap that is in connection with the brush head toothpaste passageway and which is moveable into an open position to allow for cleaning of the brush head toothpaste passageway between uses.
BACKGROUND ART
It can often be desirable to have a toothbrush provided with a quantity of toothpaste which is stored in the handle and which is dispensable onto the bristles of the toothbrush from dispensing orifices provided through the brush head and adjacent to the brush bristles as needed. Although such toothbrushes are known, they can become contaminated between uses by mouth fluids that seep into the toothpaste passageways through the dispensing orifices. It would be desirable, therefore, to have toothbrush with toothpaste delivery system that included a back cap on the brush head that could be removed or opened after brushing and which could be washed out so that contamination occurring during brushing can be removed.
GENERAL SUMMARY DISCUSSION OF INVENTION
It is thus an object of the invention to provide a toothbrush with toothpaste feed system that includes a toothpaste cartridge feed handle, a hollow brush head, a resilient hinged neck structure connected between the toothpaste cartridge feed handle and the hollow brush head and providing a neck toothpaste passageway between a toothpaste feed end of a toothpaste cartridge cavity within toothpaste cartridge feed handle and a brush head toothpaste passageway formed within hollow brush head, and an accordion fold toothpaste filled cartridge with a rupturable perforated foil end that is sized to fit into the toothpaste cartridge cavity with the rupturable perforated foil end positioned within toothpaste feed end of toothpaste cartridge cavity; toothpaste cartridge feed handle having a rotatable cap and cartridge compressing slide bar that are movable to allow for insertion of the accordion fold toothpaste filled cartridge into the a toothpaste cartridge cavity through a hinged opening provided between the neck of the brush head and the toothpaste cartridge feed handle; the cartridge compressing slide bar being slidable such that the accordion fold toothpaste filled cartridge is compressed sufficiently to rupture the rupturable foil end and force toothpaste through the neck toothpaste passageway and the brush head toothpaste passageway and out onto the brush bristles through a number of toothpaste dispensing openings formed through the exterior of the hollow brush head and positioned adjacent to the bristle bottoms of the brush bristles; the hollow brush head further including a flip open back cap that is in connection with the brush head toothpaste passageway and which is moveable into an open position to allow for cleaning of the brush head toothpaste passageway between uses.
Accordingly, a toothbrush with toothpaste feed system is provided. The toothbrush with toothpaste feed system includes a toothpaste cartridge feed handle, a hollow brush head, a resilient hinged neck structure connected between the toothpaste cartridge feed handle and the hollow brush head and providing a neck toothpaste passageway between a toothpaste feed end of a toothpaste cartridge cavity within toothpaste cartridge feed handle and a brush head toothpaste passageway formed within hollow brush head, and an accordion fold toothpaste filled cartridge with a rupturable perforated foil end that is sized to fit into the toothpaste cartridge cavity with the rupturable perforated foil end positioned within toothpaste feed end of toothpaste cartridge cavity; toothpaste cartridge feed handle having a rotatable cap and cartridge compressing slide bar that are movable to allow for insertion of the accordion fold toothpaste filled cartridge into the a toothpaste cartridge cavity through a hinged opening provided between the neck of the brush head and the toothpaste cartridge feed handle; the cartridge compressing slide bar being slidable such that the accordion fold toothpaste filled cartridge is compressed sufficiently to rupture the rupturable foil end and force toothpaste through the neck toothpaste passageway and the brush head toothpaste passageway and out onto the brush bristles through a number of toothpaste dispensing openings formed through the exterior of the hollow brush head and positioned adjacent to the bristle bottoms of the brush bristles; the hollow brush head further including a flip open back cap that is in connection with the brush head toothpaste passageway and which is moveable into an open position to allow for cleaning of the brush head toothpaste passageway between uses.
