Dish cleaning brushes
View Patent ↗Disclosed is a hand-held dish cleaning brush that includes an elongate handle with a scrubbing head at one end, the scrubbing head including a working part of an elastomer integrally formed with a plurality of bristles and with a plurality of scraping projections that are formed as an array of scraping teeth, wherein the bristles are not directly aligned with but off-set from the scraping teeth and pass between the scraping teeth when flexed forwardly or rearwardly toward the scraping teeth.
1. A hand-held dish cleaning brush that comprises an elongate handle with a scrubbing head at a distal end, the brush having a distal end furthest from the handle and a proximal end furthest from the scrubbing head and the brush having a longitudinal axis running between the distal and proximal ends of the brush, the scrubbing head including a working part of an elastomer integrally formed with a plurality of bristles and with a plurality of scraping projections that are formed as an array of scraping teeth, wherein the bristles are not directly aligned with the scraping teeth along the longitudinal axis of the brush but off-set from the scraping teeth, the bristles and the scraping projections being arranged such that the bristles pass between the scraping teeth when the bristles are flexed longitudinally towards the scraping teeth along the longitudinal axis of the brush.
2. The hand-held dish cleaning brush as claimed in claim 1 , wherein the bristles and scraping teeth nearer the front/distal end of the brush are longer than those farther away from the front/distal end of the brush.
3. The hand-held dish cleaning brush as claimed in claim 2 , wherein the bristles and scraping teeth are progressively of shorter length the greater their distance from the front/distal end of the brush.
4. The hand-held dish cleaning brush as claimed in claim 1 , wherein the elastomer is a thermoplastic elastomer.
5. The hand-held dish cleaning brush as claimed in claim 4 , wherein the elastomer is a thermoplastic copolymer.
6. The band-held dish cleaning brush as claimed in claim 1 , wherein the distal end of the handle and working part of the head is oriented at an angle to the main length and proximal end of the handle of the brush in order to facilitate application of substantial manual handling pressure onto the handle and thereby through the head.
7. The hand-held dish cleaning brush as claimed in claim 1 , wherein the bristles are at least partially shielded by at least one scraping projection.
8. The hand-held dish cleaning brush as claimed in claim 1 , Wherein the scraping teeth are less flexible, broader projections than the bristles.
9. The hand-held dish cleaning brush as claimed in claim 1 , wherein one or more scraping projections are positioned on the brush forward of the bristles, closer to the distal end of the brush than some or all of the bristles.
10. The hand-held dish cleaning brush as claimed in claim 1 , wherein the scraping teeth are interspersed among the bristles.
11. The hand-held dish cleaning brush as claimed in claim 1 , Wherein the scraping teeth are in rows.
12. The band held dish cleaning brush as claimed in claim 1 , wherein the scraping teeth alternate with the bristles longitudinally of the brush.
13. The hand-held dish cleaning brush as claimed in claim 1 , wherein a row of scraping teeth is substantially parallel to a row of bristles.
14. The hand-held dish cleaning brush as claimed in claim 1 , wherein the dish cleaning brush is generally flexible.
15. The hand-held dish cleaning brush as claimed in claim 1 , wherein the dish cleaning brush has an undulating form in side view.
16. The hand-held dish cleaning brush as claimed in claim 15 , wherein the dish cleaning brush has a substantially sigmoidal (S-shaped) form in side view.
17. The hand-held dish cleaning brush as claimed in claim 1 , wherein the scraping teeth are projections from the head that are less flexible than the bristles and presenting an elongate scraping form/end edge.
18. The hand-held dish cleaning brush as claimed in claim 1 , wherein the scraping teeth are substantially shorter than adjacent bristles.
19. The hand-held dish cleaning brush as claimed in claim 1 , wherein the scraping teeth are generally substantially broader than the bristles, being of a large cross-sectional area and relatively flattened/planar.
20. The hand-held dish cleaning brush as claimed in claim 1 , wherein the scraping teeth are wider/of greater spread laterally/transverse of the longitudinal axis of the brush/handle than they are longitudinally of the brush/handle.
