A brush for applying liquid or emulsion material such as toothpaste, hair-dye, cleaning material, etc., has a handle, a rod having bristles, sponge, etc. at its head and a pumping mechanism accommodated in the handle. The rod is slidably held, at its rear end, by the main body of the handle. When the rod is pushed rearward and thereafter released, the pumping mechanism is operated so as to such the material from a container forming a part of the handle and feed the sucked material to the head of the rod.

A brush for applying liquid or emulsion material comprising: (a) a handle having a container for containing material in liquid or emulsion form and a main body, a rear end of which is connected detachably to a mouth of the container, the container having a movable bottom body which moves along an inner wall of the container as the material is sucked through the mouth of the container; (b) a rod provided, at its head, with brush means for application of the material and slidable inserted, at its root portion, into a forward bearing portion of the main body in such a manner that rotation of the rod can be avoided and the rod can be reciprocated axially, and the rod having a material feeding passage extending from its root portion to the brush means at the head of the rod; (c) a pumping mechanism disposed within the main body for sucking the material from the container and feeding the sucked material to the head of the rod, and operated in accordance with reciprocal axial movements of the rod, the pumping mechanism including a suction chamber disposed within the main body and sealing means within the suction chamber for keeping the suction chamber airtight in order to prevent foreign matters from being sucked thereinto and for effecting a vacuum in the suction chamber to suck the material from the container into the suction chamber, the suction chamber being in fluid communication with the material feeding passage in the rod and the mouth of the container, the sealing means being connected to the rod for reciprocal axial movement therewith for pumping material to the bursh means and sucking material out of the container; (d) elastic means dipsosed within the suction chamber for biasing the rod in an axial position with respect to the main body of the handle; (e) a rotation preventing means including an operational projection formed on a peripheral surface of the root portion of the rod and functioning as a pushing member on which a finger is put when the rod is pushed axially; and (f) a slit means, axially provided in a bearing portion of the main body, for slidably receiving the operational projection.
