Claims9
An improvement in a toothbrush comprising a substantially planar head and a handle, especially for combining brushing of the teeth and massage of the gums, and comprising a plurality of toothbrush bristles one end of which is attached to the head of said toothbrush and the other end of which extends freely from the head of said toothbrush, said toothbrush bristles of ordinary cleaning function being arranged in combination with other bristles effecting massage functions, characterized in that the improvement resides in that the toothbrush head comprises an inner area having substantially vertically arranged individual bristles effecting cleansing function, and that said toothbrush head also comprises integrally therewith at least one outer group of substantially vertically arranged individual bristles of length lower than said cleansing bristles, said outer bristles having a rounded portion associated therewith for massage function.
A method for manufacturing a toothbrush, characterized by the following steps:
- providing a toothbrush (101) with original bristles of equal length (H) and having a relatively soft quality and outer bristles having a stiffness greater than that of said original bristles,
- at a later stage further processing a number of said outer bristles (104n, 105n) for the reduction of the length (h) thereof and providing rounded free end portions (106), so that the toothbrush head comprises an inner area having substantially vertically arranged individual bristles effecting cleansing function, and that said toothbrush head also comprises integrally therewith outer groups of substantially vertically arranged individual bristles of length lower than said cleansing bristles said outer bristles having a rounded top portion associated therewith for massage function.
A method for manufacturing a toothbrush comprising a handle, a toothbrush head, and bristles, characterized by the following steps:
- providing a toothbrush (301) having a first number (303a) of bristles of equal length (H1) and having a relative soft quality, arranged at the front end portion (301A) of the toothbrush head (301), and providing a second plurality of bristles (303b) on a second portion (301B) of the head (301) of the toothbrush, said second plurality of bristles being stiffer than said first plurality of bristles,
- further treating a number of outer bristles (304n, 305n) of said second plurality of bristles (303b) for the reduction of the length (h3) thereof such that the height of said outer bristles is less than the height of the remaining second plurality of bristles, and providing on said outer bristles rounded free end portions (306).
