Abstract
Abstract A brush including a brush head and a container from which a viscous substance is dispensed through passages in the brush head directly to the region of the bristles. The flow of the substance to the bristles is manually controlled and the brush head forms an extension of the container which functions as a handle. The container can have a knob for advancing a follower to dispense the substance in response to rotation of the knob. The container can also be of the pressurized type where dispensing the substance is controlled by manipulating a valve. The pressurized container has a flexible wall section which permits locating the valve actuator within the pressurized part of the container so there is no danger of leakage at the connection between the brush head and the container. The brush and container can be used as a self-dispensing toothbrush.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
162 words
A pressurized container for dispensing a viscous material through passages of a brush head to the region of bristles of the head comprising, in combination wall means defining a sealed container having means defining a dispensing opening; connector means for securing a brush head to the container in sealed relation to the dispensing opening; a valve between the dispensing opening and a pressurized region of the container, the valve normally closing the dispensing opening; a flexible section in a defined region of the wall means; and an actuator operably associated with said valve and extending to a location adjacent the flexible wall section, the actuator being movable in response to manual movement of the resilient wall section to open the valve to permit controlled dispensing of material from the container to the dIspensing opening and the bristles of a brush head secured to the container, the resilient wall section including bellows means in the resilient wall section defining a manually operable button.
Claim 2
Dependent Claim
162 words
A pressurized container for dispensing a viscous material through passages of a brush head to the region of bristles of the head comprising, in combination wall means defining a sealed container having means defining a dispensing opening; connector means for securing a brush head to the container in sealed relation to the dispensing opening; a valve between the dispensing opening and a pressurized region of the container, the valve normally closing the dispensing opening; a flexible section in a defined region of the wall means; and an actuator operably associated with said valve and extending to a location adjacent the flexible wall section, the actuator being movable in response to manual movement of the resilient wall section to open the valve to permit controlled dispensing of material from the container to the dIspensing opening and the bristles of a brush head secured to the container, the resilient wall section including bellows means in the resilient wall section defining a manually operable button.
Claim 3
Dependent Claim
40 words
A pressurized container according to claim 1 wherein the valve actuator is rigid with the valve and has an L-shaped stem so that movement of the actuator by depressing the flexible wall section tilts the valve to an open position.
Claim 4
Dependent Claim
32 words
A pressurized container according to claim 2 which further includes means adjacent the valve stem and engaging the stem to prevent rotation of the stem with respect to the flexible wall section.
Claim 5
Dependent Claim
36 words
A pressurized container according to claim 1 wherein the pressure within the container presses the valve toward its normally closed position; and spring means engage the valve and urge the valve toward its normally closed position.
Claim 6
Dependent Claim
48 words
A pressurized container according to claim 1 wherein said actuator includes a stem rigid with a moveable element of the valve; a spring encircles the stem to urge the valve toward its closed position; and the spring permits tilting of the valve element with respect to its seat.
Claim 7
Dependent Claim
75 words
A pressurized container according to claim 1 wherein the pressurized container is the handle of a toothbrush; the brush head is a toothbrush head; a support stem projects from the toothbrush head, the support stem having passage means connecting an inlet at one end of the stem to an outlet adjacent bristles of the toothbrush head; means adjacent the inlet and cooperating with the connector means for removably securing the toothbrush head to the container.
Claim 8
Dependent Claim
54 words
A pressurized container according to claim 6 wherein the means adjacent the inlet comprises an internally threaded end of the stem; the means adjacent the dispensing outlet comprises an externally threaded nipple defining the dispensing opening; said nipple sealing against the stem to prevent leakage between the dispensing opening and inlet of the stem.
