The invention relates to a toothbrush having a head area comprising cleaning elements, a grip area, and a neck area, which connects the head and the grip areas to each other, wherein the toothbrush is configured having a first component made of plastic, and at least one further second component made of plastic, wherein the first component has a relief structure that is covered by the second component. The relief structure comprises high regions having the shortest distance to the outer surface of the second component, and low regions having the greatest distance to the outer surface of the second component, and the relief structure has intermediate regions adjacent to the high and low regions, the distance to the outer surface of the second component of the intermediate regions being between that of the high and low regions.
A toothbrush having a head area (1) that has cleaning elements (4), a grip area (2), and a neck area (3) that connects the head and grip areas to one another, wherein the toothbrush is fashioned with a first component (X) made of plastic and at least one additional second component (Y) made of plastic, wherein the first component (X) has a relief structure (11) covered by the second component (Y), wherein the relief structure (11) has high regions (14) with the shortest distance (P, O) to the outer surface (8) of the second component (Y), and has low regions (13) with the greatest distance to the outer surface (8) of the second component (Y), and wherein the relief structure (11) has regions of intermediate height (12) adjacent to the high and low regions, whose distance to the outer surface (8) of the second component (Y) is between that of the high and low regions.
The toothbrush according to any one of the preceding claims, characterized in that the relief structure (11) is situated exclusively on the upper side (8) of the grip area (2), said upper side corresponding to the side on which the tooth-cleaning elements (4) of the head area (1) are provided.
The toothbrush according to any one of the preceding claims, characterized in that the edges of the relief structure (11) are rounded with a radius of >0.2 mm.
The toothbrush according to any one of the preceding claims, characterized in that the first component (X) is formed from hard plastic.
The toothbrush according to any one of the preceding claims, characterized in that the second component (Y) is fashioned from hard plastic.
A toothbrush, characterized in that in addition to polypropylene or some other hard
The toothbrush according to any one of the preceding claims, characterized in that colorant components are admixed to the second component (Y) in a proportion of 0.5% to 6%, in particular 1% to 5%.
The toothbrush according to any one of the preceding claims, characterized in that the regions of intermediate height (12) have a surface of >1 mm2.
The toothbrush according to any one of the preceding claims, characterized in that the regions of intermediate height (12) enclose a positive or negative angle of 0° to 75°, in particular of 0° to 60°, relative to a planar horizontal surface along the longitudinal axis (30) of the toothbrush.
The toothbrush according to any one of the preceding claims, characterized in that the grip area (2) is fashioned from the first component (X) in a proportion of 20% to 80%, in particular of 30% to 70%, and from the second component (Y) in a proportion of 20% to 80%, in particular of 30% to 70%.
The toothbrush according to any one of the preceding claims, characterized in that the first component is bonded to the second component (X, Y) by mechanical means (9, 10, X, Y).
The toothbrush according to one of the preceding claims, characterized in that the relief structure (11) extends onto or is provided on a side of the toothbrush that differs from the side of the toothbrush on which the injection point (17, 18) for one or two components (X, Y) is situated.
The toothbrush according to any one of the preceding claims, characterized in that the relief structure (11) is situated on the same side of the toothbrush as the cleaning elements (4) for the teeth.
The toothbrush according to any one of the preceding claims, characterized in that the relief structure (11) is situated on the upper side (8) of the grip, and the injection point (17, 18) for one or two components (X, Y) is situated opposite thereto, on the underside of the grip (2).
The toothbrush according to any one of the preceding claims, characterized in that the high regions (14) have segments that run transverse, or that run transverse with a curve, to the longitudinal axis (30).
