Abstract:
Apparatuses and methods for producing improved photographs suitable for measuring teeth whiteness with a handheld camera using a camera jig are provided. The camera jig includes a base that contacts a surface. The camera jig also includes a light shield made from a tubular structure defining an interior cavity. The camera jig further includes a slot in the tubular structure that supports the handheld camera at a predetermined distance from a target, which may be teeth of a user. The slot aligns a lens of the handheld camera with the target. Further, the light shield blocks substantially all ambient light, other than light of a light source of the handheld camera, from the target as it is photographed.
Abstract:
Disclosed is an oral care implement, comprising: a body comprising a handle and a head at an end of the handle; the body having a cavity therein for storing an oral care fluid; the head having at least one oral care element extending therefrom, and a fluid outlet through which the oral care fluid is dispensable to an exterior of the oral care implement; a passageway fluidly connecting the cavity with the fluid outlet; a mechanism for introducing air into the cavity from the exterior of the oral care implement; and a control valve on the head movable relative to the head between a first position for preventing fluid flow from the cavity through the fluid outlet and a second position for permitting fluid flow from the cavity through the fluid outlet.
Abstract:
Disclosed is an oral care implement, comprising: a body comprising a handle, a head having at least one oral care element extending therefrom, and at least one fluid outlet; a reservoir in the body and for storing an oral care fluid; and a pump in the body for pumping the oral care fluid from the reservoir towards the fluid outlet, wherein the pump comprises an umbrella check valve circumferentially surrounding a duckbill check valve. Also disclosed is a method of manufacturing an oral care implement, comprising: providing a body comprising a base having first and second holes extending therethrough; and fitting to the body a unitary component comprising first and second valves at a position at which the first valve blocks the first hole and the second valve blocks the second hole, wherein the first valve comprises an umbrella check valve that circumferentially surrounds the second valve.
Abstract:
An oral care system including a handle and a toothbrush member and dispenser rotatably coupled to the handle. In one aspect, the toothbrush member is rotatably coupled to the handle for rotation between: (1) a first state in which the toothbrush member is positioned within the cavity; and (2) a second state in which the toothbrush member extends from the distal end of the handle. The first dispenser comprises a first store of oral care material and is rotatably coupled to the handle for rotation between: (1) a first state in which the first dispenser is positioned within the cavity; and (2) a second state in which the first dispenser extends from the distal end of the handle. In another aspect, the invention can be an oral care system comprising first and second dispensers and a toothbrush member rotatably coupled to a handle.
Abstract:
A method of producing arginine bicarbonate is provided including reacting an arginine slurry with a source of carbon dioxide gas under elevated temperature and low pressure to form a solution of at least 50% arginine bicarbonate, and recovering arginine bicarbonate from the solution.
Abstract:
An oral care implement (1) includes a head (12), a handle (10), a neck portion (11) connecting the head and the handle, and a reservoir (15) which contains at least one active agent. The implement has an activator (22) for activating a delivery device which delivers the active agent to one or more outlets (50). A powered delivery device (18) disposed in the head to deliver a liquid from the reservoir via the outlet. A wide variety of types of active agents may be administered at appropriate and accurate doses for therapeutic, hygienic, and/or other benefit.
