Abstract
The present invention is directed to a toothbrush having a handle portion, a neck portion and a head (1), said head (1) being provided with bristle tufts (6) arranged in a complex internal geometry by means of the stapling technique. To enable a visually flawless molding to be produced, material cross-sections in the head (1), in particular in the area of the blind-end holes (11, 12) provided for tufting, are taken into consideration.
Claims (14)
1. A toothbrush having a handle portion and a neck portion connecting the handle portion with a head (1), said head (1) having a brushing side (5) and a rear side (21) opposite thereto, said brushing side (5) including a plurality of bristle tufts (6) for cleaning the teeth, said tufts being attachable in the head (1) through tufting apertures (10) using an anchor (15), with each tufting aperture being (10) assigned a blind-end hole (11, 12, 13, 14) having sidewalls (16) and a bottom (17, 18), wherein provision is made for a chamfer or radius (19) in the transition area between the bottom (17, 18) and the sidewalls (16), with a cross-sectional area of the head (1) between a first bottom (17, 18) and the rear side (21) differing from a cross-sectional area of the head between a second bottom (17, 18) and the rear side (21), and said first bottom and said second bottom (17, 18) being arranged in the head in such a way that the minimum distance y between the first bottom (17, 18) and the rear side (21) as well as the minimum distance x between the second bottom (17, 18) and the rear side (21) are each in the range of between 0.5 and 2.5 mm.
2. The toothbrush according to claim 1, characterized in that the first and the second bottom (17, 18) are arranged in the head (1) in such a way that the minimum distance x and y amounts to between 0.8 and 2 mm each.
3. The toothbrush according to claim 1 or 2, characterized in that the head (1) includes third and fourth blind-end holes (11, 12) which can be tufted with bristle tufts (6a) to the same depth, said third and fourth blind-end holes (11, 12) being constructed such that their bottoms (17, 18) extend to different depths.
4. The toothbrush according to claim 3, characterized in that in the fourth blind-end hole (12) the chamfer or radius (19) is followed by a constriction (20) and an adjoining further radius or chamfer (19) and thereafter by the adjoining bottom (18).
5. The toothbrush according to at least one of the preceding claims, characterized in that the head (1) has a first interior region and a second interior region, said first interior region (9) being made of hard plastic and said second interior region including an electrically operable function element (4) or part thereof.
6. The toothbrush according to claim 5, characterized in that provision is made for an injection point for the hard plastic of the head (1) on the neck or on the handle portion and that the blind-end holes (11, 12, 13, 14) are spaced at different relative axial distances to the injection point on the head (1), and that in the hard plastic of the head (1) a free space is provided for the function element (4) between said blind-end holes (11, 12, 13, 14) spaced at different relative distances.
7. The toothbrush according to at least one of the preceding claims, characterized in that the head includes at least one fifth blind-end hole (13) which is arranged adjacent to and above the function element (4) and is shorter than the third and fourth blind-end holes (11, 12, 14).
8. The toothbrush according to at least one of the preceding claims, characterized in that the rear side of the head (1) is made at least in part of the same hard plastic as the brushing side (5).
9. The toothbrush according to at least one of the preceding claims, characterized in that the head is formed of a hard plastic material which exhibits more than 1% material shrinkage after an injection-molding operation.
10. The toothbrush according to at least one of the preceding claims, characterized in that the head is formed of polypropylene hard plastic.
11. The toothbrush according to at least one of the claims 1 to 9, characterized in that the head is formed of polyethylene, POM, SAN or copolyester hard plastic.
12. The toothbrush according to at least one of the preceding claims, characterized in that the head (1) includes first and second bristle tufts (6a, 6b, 6c) of different lengths from the bottom (17) of the blind-end hole to the bristle end, said first and second bristle tufts (6a, 6b, 6c) being of approximately equal length from the brushing side (5) to the bristle end.
13. The toothbrush according to at least one of the preceding claims, characterized in that provision is made in the head for at least one blind-end hole having its central axis arranged at an angle to the perpendicular on the brushing side.
14. A method of manufacturing a toothbrush according to claim 1.
