A method of manufacturing a unitary toothbrush head having a base and filaments extending therefrom. The method includes steps of injecting molten plastic material into a mold cavity having a pre-base cavity and a filament cavity extending therefrom; compressing the molten plastic material, once it is essentially filling the pre-base cavity, by impressing a punching tool into the molten plastic material from the rear side of the pre-base cavity being opposite to a side from which the filament cavity extends; and filling the filament cavity with the molten plastic material under the continuous impression of the punching tool.

Examples of the present disclosure include apparatus and methods for making a brush handle assembly. Specifically, the present disclosure is for a brush handle assembly comprising a flexible handle, an intermediate connector, and a ferrule. In particular, the present disclosure is for an improved interface between each of the flexible handle, the intermediate connector, and the ferrule for an improved construction providing increased durability and longevity.

A dispensing paintbrush includes a handle, a brush head connected to the handle, and bristles attached to the brush head to apply a fluid to a surface. A coupler is attached to the handle and is configured to connect to a fluid source. A nozzle is attached to the coupler and is configured to dispense the fluid to the bristles. The nozzle extends within the bristles and terminates at a position from the brush head that is less than one half the length of the bristles.

A toothbrush comprised at least one unitary brush head having a base and at least one filament and extending therefrom and having a free end terminating with a tip, wherein the filament has a length of from 6.0 mm to 20.0 mm between the base and the free end, and wherein the unitary brush head is made from a plastic material that has a melt flow rate of not greater than about 30 g/10 min measured in accordance with ISO 1133.
