Abstract
A method of making a toothbrush head by molding a head by having two distinct portions which are spaced a predetermined distance from each other. During molding, at least one tooth cleaning element is secured to one of the two head portions. After molding, heat is applied to at least that part of the head where the two head portions connect. Thereafter, at least that part of the head where the two head portions connect is cooled.
Claims (27)
1. A toothbrush head, comprising a top surface having a plurality of holes extending therefrom, a plurality of tooth cleaning elements, and wherein each of the tooth cleaning elements extends from a base support being connected to an anchor pivot having a hole therethrough and wherein each anchor pivot is disposed within one of the plurality of holes extending from the top surface of the head.
2. The toothbrush head of claim 1, wherein each anchor pivot has an end portion and an intermediate portion that is smaller than the end portion.
3. The toothbrush head of claim 1, wherein the plurality of tooth cleaning elements are non-rotatable.
4. The toothbrush head of claim 1, wherein the plurality of tooth cleaning elements are rotatable.
5. The toothbrush head of claim 1, wherein the plurality of tooth cleaning elements comprise an elastomeric fin.
6. The toothbrush head of claim 5, wherein the elastomeric fin comprises a textured surface.
7. The toothbrush head of claim 6, wherein the textured surface includes ribs or dimples.
8. The toothbrush head of claim 6, wherein the textured surface extends from 2-mil away from the fin.
9. The toothbrush head of claim 1, wherein the tooth cleaning elements comprise a tuft of bristles.
10. The toothbrush head of claim 9, wherein the tooth cleaning elements are crimped or notched.
11. The toothbrush head of claim 1, wherein the tooth cleaning elements are snap-fit to the head.
12. A toothbrush head, comprising a top surface, and one or more tooth cleaning elements extending from the top surface, each of the one or more tooth cleaning elements comprising a tooth cleaning portion, a base support, and an anchor pivot, wherein one end of the tooth cleaning portion is secured to a first end of the base support and a first end of the anchor pivot extends from a second end of the base support and a first portion of the anchor pivot near the anchor pivot's first end is smaller than a second portion of the anchor pivot located near a second end of the anchor pivot
13. The toothbrush head of claim 12, wherein the tooth cleaning portion comprises bristles.
14. The toothbrush head of claim 12, wherein the anchor pivot has an opening therethrough, such that when the anchor pivot is pressed into an entrance of a hole in the top surface of the head, the entrance being smaller than the second portion of the anchor portion, the opening temporarily gets smaller to allow the second portion of the anchor pivot to flex and pass through the entrance.
15. The toothbrush head of claim 12, wherein the tooth cleaning portion is made of polybutylene terephthalate.
16. The toothbrush head of claim 12, wherein the base support and the anchor pivot are a unitary structure.
17. The toothbrush head of claim 12, wherein the tooth cleaning portion is elastomeric.
18. The toothbrush head of claim 16, wherein the tooth cleaning portion is in the form of a fin.
19. The toothbrush head of claim 11, wherein the anchor pivot is pivotably disposed within a hole having an entrance in the top surface of the head.
20. The toothbrush head of claim 19, wherein the head has a bottom surface and the hole extends from the top surface to the bottom surface.
21. The toothbrush head of claim 20, wherein the anchor pivot has a larger section further from the base support than a smaller section of the anchor portion, the larger section and the smaller section each having a length which is longer than a width
22. The toothbrush head of claim 21, wherein a first portion of the hole near the bottom surface of the head has about the same length and width as the length and width of the larger section of the anchor pivot, the larger section of the anchor pivot residing in the first hole portion.
23. The toothbrush head of claim 22, wherein the hole has a second portion near the top surface of the head, the second hole portion having a length which is shorter than a length of the first hole portion.
24. The toothbrush head of claim 23, wherein the second hole portion has a width which is about the same as the width of the first hole portion where the two hole portions meet, the width of the second hole portion flaring from where the hole portions meet toward the top surface.
25. The toothbrush head of claim 24, wherein the base support is located outside of the hole.
26. The toothbrush head of claim 12, wherein at least one of the one or more tooth cleaning elements is snap-fit to the head.
