The invention relates to a brush comprising a support made of a plastically deformable plastic material for disposing bristle clusters (13) thereon, the support having a plurality of cluster holes (14) each serving to accommodate one bristle cluster (13), the bristle clusters (13) each being fixed in a cluster hole (14) by means of a clip (16), and the clips (16) being provided with discontinuous structural elements at least in the area of clip projections (23, 24) on at least one longitudinal side (22) disposed essentially parallel to a cluster hole axis, wherein the structural elements are disposed at a distance to the longitudinal edges of the clip (16).

Pruning plants that exude sticky sap may leave pruners gummed up and barely useable. Cleaning edged cutting tools presents injury risks to nursery and farm workers, so a need for rapid and effective cleaning machines exists. This pruner cleaning machine includes a motorized rotor assembly of scrubber discs facing each other and a helical center brush disposed between them. The scrubber discs include helical ramps and step faces at the ends of these ramps which conform to the ends of the helical scrubber, so that the spacing between the scrubber discs may be accurately controlled by the number of turns of the helical scrubber, including partial turns. The rotor may be reconfigured for various types of pruners by selecting from among various lengths of helical scrubbers. Properly configured, by using this machine and its inventive scrubbing rotor, gummed up pruners may be cleaned in seconds.

A handle for a personal-care implement comprises a housing having an inner cavity, the housing having a proximal end closest to a head repeatably attachable to and detachable from the handle, and a distal end, the distal end being opposite the proximal end; a swivel-mounted connector-pressure-sensor unit unitarily made as one piece, the connector-pressure sensor unit comprising a connector extending through an opening at the proximal end of the housing, and a pivot lever accommodated within the inner cavity of the housing and extending towards the distal end of the housing, the pivot lever being attached to the housing via a pivot axis.

The disclosure relates to a method of manufacturing a toothbrush handle and includes heating a pelletized polyolefin based (preferably polyethylene based) polymeric material having a biobased content of at least 60% by weight, and injection moulding the heated polymeric material into a moulding cavity thereby forming a toothbrush handle. The moulding cavity has the shape of a toothbrush handle comprising a gripping portion and a bristle support portion. The disclosure also relates to toothbrush handle, a toothbrush and a method of manufacturing a toothbrush.
