Abstract
A method () for manufacturing a brush head (). The method includes the steps of providing a plurality of polypropylene bristle tuft retention rings (), and inserting a respective nylon bristle tuft () into each of the bristle tuft retention rings. Heat is applied to each bristle tuft proximal end () at a temperature sufficient to at least partially melt the bristle tuft proximal end and create a proximal head portion (). The platen () of the brush head is positioned in relation to the retaining rings () and proximal head portions () to define a space () in relation to the proximal head portions for injection of a thermoplastic elastomer, and the thermoplastic elastomer is injected into the space to create an elastomeric matrix () that at least partially encompasses the neck and the proximal head portions.
