    Abstract: A fluid dispensing oral care implement having a low profile pump includes a head, a reservoir for storing an oral care fluid, at least one liquid outlet in the head, and a pump. The pump includes a flexible membrane movable between alternating pump intake and discharge motions. The pump includes inlet and outlet flap valves, which may be formed integrally from portions of the membrane. In one embodiment, the valves are integrally formed in the membrane as flexible cantilevered tabs movable between open and closed positions. In some embodiments, the pump may be mounted in the toothbrush head or forms the head. In some embodiments, the pump may be disposed in a neck or a handle portion of the toothbrush.

    CPC classification number: C07C219/06

    Abstract: The invention provides fabric conditioning compositions, which include as the conditioning agent, one or more quaternary ester ammonium salt compounds, which include a mixture of quaternary mono-, di- and tri-ester ammonium salt components, wherein the amount of quaternary diester ammonium salts is greater than about 40% by weight, and the amount of quaternary triester ammonium salts is less than about 20% by weight based on the total amount of quaternary ester ammonium salts. The composition contains a high level of quaternary diester ammonium salt content, and low level of quaternary triester ammonium salt content.

    Abstract: A system for detecting blood in an oral cavity during toothbrushing. The system may include a toothbrush having a sensor that is configured to emit first light at a first wavelength and second light at a second wavelength, receive reflected portions of the first and second light, and generate a first signal indicative of a first intensity of the reflected portion of the first light and a second signal indicative of a second intensity of the reflected portion of the second light. The system may include a processor operably coupled to the sensor, the processor being configured to receive the first and second signals and calculate a ratio of the first intensity to the second intensity to determine whether hemoglobin/blood is present in the oral cavity. The processor may be a part of the toothbrush or a part of a portable electronic device such as a smart phone.
