A brush head () and a method for manufacturing a welded tuft assembly () for a brush head (). The method includes insertin g a bristle tuft () into an opening () in a retention element (). A proximal end of the bristle tuft () and a proximal side () of the retention element are laser welded to at least partially melt the bristle tuft and at least a portion of the proximal side of the retention element together to create a merged proximal end head portion () that holds the welded tuft assembly together.

Brush head manufacturing method

A brush head () and a method for manufacturing a brush head. The method includes forming a plurality of retention elements () each having an opening () therethrough. The retention elements () are positioned into corresponding recesses of a plate. A bristle tuft () is inserted into each of the openings of the retention elements. A proximal end () of each bristle tuft is bonded to the corresponding proximal side of the retention element to form a merged proximal end head portion () that secures the bristle tufts and the corresponding retention elements together as a plurality of merged tuft assemblies (). A neck () of the brush head is positioned in relation to the merged tuft assemblies. A platen () of the neck and the merged tuft assemblies is at least partially encompassed in a matrix ().

A housing interlock () for a power toothbrush () configured to improve the durability of the toothbrush and to simplify the assembly process. The housing interlock () provides for tolerance mitigation and shock protection, and also provides housing interlock tabs () such that the housing interlock can secure the components within the housing.

Housing interlock design

A grating disc () arranged to be rotatably mounted within a food processor (), to rotate in a direction of rotation (), which grating disc () comprises at least one grating tooth () for grating food to be processed. The grating disc () comprises at least one groove () extending from an inner region () to an outer edge () of the grating disc () to assist in guiding food particles outwardly during use of the food processor (). With the provision of a grating disc in accordance with the present invention, improved output of processed food is accomplished in that the at least one groove with assistance of centrifugal force guides the processed food outwardly for retrieval.
