A personal care implement, such as an oral care implement, that includes a body containing a supply of a fluid. A flow barrier is positioned with a first surface adjacent to the supply of fluid and a second surface opposite the first surface. The flow barrier allows flow of the fluid through the flow barrier for application to a biological surface when the flow barrier is compressed and prevents or inhibits flow of another fluid that is in contact with the second surface of the flow barrier through the flow barrier in a static state. In certain embodiments, the fluid in the supply may have a first viscosity and a first surface tension and the another fluid may have a second viscosity and a second surface tension such that one of the first and second viscosities and one of the first and second surface tensions are different from each other.

In one aspect, the present disclosure provides a brush for applying a formulation, the brush having a core having an outer surface and a longitudinal axis, a plurality of bristle rings protruding from the core and spaced apart along the longitudinal axis, each bristle ring having at least 6 bristles spaced radially apart around the outer surface of the core, and a high density zone that covers at least a portion of the outer surface of the core, the high density zone having an equivalent 360 degree linear bristle density of 13 to 31 whole bristles per 0.5 mm of length along the outer surface of the core measured along the longitudinal axis, and a surface bristle density of 3 to 5 bristles per square millimeter of area of the outer surface of the core.

A hand attachable animal washing apparatus, attachable upon the hand of a user, is provided enabling singlehanded control of waterflow and application of water into the coat of an animal. Control of waterflow though a molded body member is enabled by operation of a compressible portion disposed to control a valve assembly disposed interiorly within the molded body member. A proximal arced edge is disposed projected rearwardly from the molded body member and curved downward to direct waterflow away from a user operating the device, particularly when the device is elevated above a user, as when washing a large animal such as a horse, for example. A user may thereby control and apply water to an animal with one hand while securing and comforting the animal with the other hand.

A surface attachable washing apparatus is provided to enable easy control of water flow through a molded body member. A valve assembly, disposed interiorly within the body member, is actuated by simple depression of an overlying portion of an obverse surface of the molded body member, to toggle a valve assembly between each of a closed position and an open position. Water flow is therefore controllable by manual pressure to alternately emit and prevent water flow sprayed through each of a plurality of outlets. At least one suction cup enables selective positioning of the molded body member upon a surface distally situated relative to an existing water outlet to which the apparatus is connected. A user may therefore position the apparatus at a desired height in the bath room, for example, to correspond with a child who can then easily control of the water flow during bath time.

A spray dispensing cleaning implement for cleaning hard to reach places includes a handle that is coupled to a bar. A plurality of bristles is coupled to and extends from a bottom of the bar. The handle is hollow and defines a reservoir that is configured to position a solution. A nozzle is coupled to the bar. A tube is coupled to the nozzle and extends into the reservoir. A pump, which is coupled to and positioned in the reservoir, is operationally coupled to the tube. A trigger is pivotally coupled to the handle and is operationally coupled to the pump. The handle is configured to be grasped in a hand of a user positioning a digit of the hand to pivot the trigger to actuate the pump to spray the solution from the nozzle onto a surface. The user brushes the bristles on the surface to clean the surface.

A hand attachable animal washing apparatus, attachable upon the hand of a user, enables singlehanded control of water flow and application of water into the coat of an animal. Control of water flow though a molded body portion is effective by singlehanded operation of a valve assembly disposed interiorly within the molded body portion. A user is enabled to open and close the valve assembly by compressing a compressible portion disposed proximally overlying the user's palm when wearing the apparatus upon one hand. A user may thereby control and apply water applied to an animal with one hand while securing and comforting the animal with the other hand.

A brush (200) for delivering a glutinous substance (168) to a workpiece (170) from an end-effector (102) is disclosed. The brush (200) comprises a body (202), having a rotational axis (238) and comprising a first channel (208) that comprises an inlet (209) and a first outlet (280). The inlet (209) is coaxial with the rotational axis (238) and the first outlet (280) is offset from the rotational axis (238). The brush (200) also comprises tufts (222), extending from the body (202) and each comprising at least one bristle (220) and a tip (227). The brush (200) further comprises a first tube (210), communicatively coupled with the first outlet (280) of the first channel (208) of the body (202).

A brush for delivering a glutinous substance to a workpiece from an end-effector is disclosed. The brush comprises a body having a rotational axis. The body comprises a first end, a second end, opposite the first end, and a channel, comprising an axial inlet and an outlet. The axial inlet is at the first end of the body and is coaxial with the rotational axis. The brush also comprises bristles, extending from the body so that the bristles are not parallel to the rotational axis of the body.

Formulation delivery systems, formulation delivery devices, and formulation cartridges for the same are provided. Formulation delivery systems include a reusable handle, a formulation dispensing assembly, and a controller. The formulation dispensing assembly includes a reciprocating nozzle assembly and a pump. The reciprocating nozzle assembly is fluidically-couplable to the formulation cartridge or the cleaning cartridge received within the reusable handle. Formulation delivery devices include a reusable handle configured to receive a formulation cartridge therein, and a formulation dispensing assembly disposed in the reusable handle. The formulation dispensing assembly includes fluid conduits, a pump fluidically connected to the fluid conduits, a reciprocating nozzle assembly, and a controller. Formulation cartridges include a reusable cartridge body and a formulation cartridge refill unit.
