A glue bottle with flow regulation comprises a bottle body, a bottle cap, and a liquid outlet cap engaged with the bottle cap through thread. The bottle cap is partially contained in the liquid outlet cap. A cavity is formed between the inner wall of the liquid outlet cap and the outer wall of the bottle cap. and is provided with a first opening and a second opening. A seal body is arranged on the top part of the bottle cap, and is positioned inside of the cavity. The position of the seal body in the cavity is adjusted by rotating the liquid outlet cap relative to the bottle cap. The closer the seal body is to the second opening, the smaller the gap is between the liquid outlet cap and the bottle cap. The glue bottle is capable of precisely controlling the quantity of the glue flowing out.

An oral care system includes a handle and a head, the handle having a proximal end and a distal end, the head being coupled to the distal end of the handle and including at least one oral surface engaging element. The oral care system further includes a mechanism including first and second housing portions, each including a first and a second end; and an applicator loaded with an oral care material and positioned within the mechanism. The first ends of the first and second housing portions are pivotably coupled to one another about a rotational axis so as to be alterable between: (1) a closed state in which the first and second housing portions form an enclosure that contains the applicator; and (2) an open state in which the second ends of the first and second housing portions are spaced from one another and the applicator is exposed.

Disclosed is an oral care implement, comprising: a body comprising a handle and a head, the body having a cavity, and the head having at least one oral care element extending therefrom; a movable wall in the cavity that divides the cavity into first and second reservoirs, the first reservoir for storing an oral care fluid; a fluid outlet through which the oral care fluid is dispensable to an exterior of the oral care implement; a passageway fluidly connecting the first reservoir with the fluid outlet; a control valve movable between a first position and a second position for preventing and permitting fluid flow from the first reservoir, respectively; a first opening fluidly connecting the second reservoir with the exterior of the oral care implement; and a first check valve for permitting and restricting air flow into and out of the second reservoir from the exterior.

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.

Disclosed is an oral care implement, comprising: a body comprising a handle, a head at an end of the handle, and at least one fluid outlet, the head having at least one oral care element extending therefrom; a reservoir in the body and for storing an oral care fluid; and a supply mechanism connected to the body, the supply mechanism comprising: a user-operable selector comprising a cam, and an actuator comprising a follower in contact with the same, the actuator operable to cause the oral care fluid to flow from the reservoir towards the fluid outlet, and wherein the cam is movable relative to the body to cause movement of the follower relative to the body and thereby operate the actuator.

An oral care system includes a first package, a second package, and a container. The first package has a first identifier associated with a first time of day. The first package contains a first unit dose suction brush. The first unit dose suction brush includes a first handle, a first cleaning head, and a first vacuum port. The first handle has a first brush first end and a first brush second end opposite the first brush first end, the first handle having a first suction channel extending from the first brush first end to the first brush second end. The first cleaning head is connected to the first brush first end. The first cleaning head includes a first suction port and a plurality of first bristles arranged in a first pattern surrounding the first suction port. The first vacuum port is located at the first brush second end.
