Abstract
A toothbrush having a handle a head extending from the handle, and a plurality of tufts of bristles secured to the head. One of the tufts is secured to the head at a location such that no other tuft is secured to the head at a location which is more distal from the handle than the location where the one tuft is secured to the head. The one tuft is angled by about 81 degrees or less relative to an imaginary line which is tangent to or co-planar with a surface of the head through which the one tuft is secured to the head. The one tuft is tilted away from the handle towards a direction along which the head extends from the handle.
Claims35
A toothbrush, comprising:
- a handle;
- a head extending from the handle;
- and
- a plurality of tufts of bristles secured to the head, one of the tufts being secured to the head at a location such that no other tuft is secured to the head at a location which is more distal from the handle than the location where the one tuft is secured to the head, the one tuft being angled by 81 degrees or less relative to an imaginary line which is tangent to or co-planar with a surface of the head through which the one tuft is secured to the head, the one tuft being tilted away from the handle towards a direction along which the head extends from the handle, a second one of the tufts being tilted towards the handle, all of the bristles of a third one of the tufts being angled at an acute angle relative to the imaginary line, the second and third tufts have different cross-sections from each other.
1 more element
A toothbrush, comprising:
- a handle;
- a head extending from the handle;
- and
- a plurality of tufts of bristles secured to the head, three of the tufts each being at an acute angle relative to an Imaginary line which is tangent to or co-planar with a surface of the head through which the three tufts are secured to the head, the three tufts being angled and aligned substantially toward the same direction, the direction being substantially parallel with the handle, the direction being substantially towards or away from the handle, a first one of the three tufts having a length, a second one of the three tufts being adjacent to the first tuft and having a length shorter than the length of the first tuft, and a third one of the three tufts being adjacent to the first tuft and having a length shorter than the length of the first tuft, a fourth tuft being secured to the head at a location such that no other tuft is secured to the head at a location which is more distal from the handle than the location where the fourth tuft is secured to the head, the cross-sectional area of the fourth tuft being at least four times as large as the cross-sectional area of any other tuft secured to the head.
1 more element
A toothbrush, comprising:
- a handle;
- a head extending from the handle;
- and
- three tufts of bristles secured to the head, the tufts each being at an acute angle relative to an imaginary line which is tangent to or co-planar with a surface of the head through which the tufts are secured to the head, two of the three tufts differing in cross-section, the three tufts being angled and aligned substantially toward the same direction, the direction being substantially parallel with the handle, the direction being substantially towards or away from the handle, a first one of the three tufts having a length, a second one of the three tufts being adjacent to the first tuft and having a length shorter than the length of the first tuft, and a third one of the three tufts being adjacent to the first tuft and having a length shorter than the length of the first tuft.
1 more element
A toothbrush, comprising:
- a head with a frontal free end and a rearward section;
- a handle connected to the head;
- tufts of bristles arranged in longitudinal rows on the rearward section of the head, tufts in a first row being tilted in a first direction towards the free end of the head, tufts in a second row being tilted towards a second direction opposite the first direction;
- and
- a further tuft of bristles secured to the frontal free end of the head and being tilted towards the first direction, the further tuft having a first length, the tufts on the rearward section of the head either having the first length or a second length, the first length being longer than the second length, each longitudinal row including tufts of bristles of the first and second lengths, adjacent tufts in a longitudinal row alternately having the first and second length.
