The present application relates to a toothbrush device having a neck and head, wherein the head comprises at least three parts of a first plastics material, at least two of the parts having bristles attached thereto, wherein the neck has the first material as primary material and wherein the bristles on the head are parted hi the longitudinal direction of the head.
There are previously known a number of toothbrushes that comprise more than one bristle portion and wherein the parts of the head bearing the bristle portions are connected to the rest of the toothbrush in such manner that they have some flexibility.
NO313653 describes a two-part bristle head, wherein the two parts of the bristle head are connected to each other and to the brush neck via a hinge piece having two opposing hinge wings. A brush with heads consisting of three or more parts is not described.
US5946759 describes flexible toothbrush heads, which heads are divided into a plurality of sections connected by hinge joints. The spaces between the sections are at least partly filled with a soft plastics material. The section boundaries run transverse to the longitudinal direction of the toothbrush and do not permit the simultaneous brushing of three tooth surfaces.
EP0611282 describes a three-sided toothbrush consisting of three bristle heads, each having an elongate flexible neck connected to a common handle. Two of the bristle heads are in opposing relationship and angled so that they both point in towards the third bristle head. A method for the manufacture of the toothbrush is also described. This method comprises moulding the three heads in one plane, optionally as a single piece, inserting bristles, trimming the bristles, optionally separating the heads by removing the runners between the heads, and bonding the three bristle heads to the same handle. This method of obtaining flexible bristle heads seems to be both costly and time-consuming.
US2002/0157202 describes a toothbrush with several toothbrush heads, wherein side brush heads are connected to a toothbrush handle via a so-called U-joint which gives each brush head individual flexibility. US5934762 and its divisional patent US6108852 disclose a toothbrush construction having two or three heads and manufacturing methods therefor. The construction consists of individual brush heads with a rigid neck that are moulded to a handle. Each brush head has limited flexibility. A method for manufacturing the brush is described which comprises a) moulding the handle, neck and heads in a first moulding step, where channels connect the individual parts, b) attaching bristles to the heads, c) splitting the construction into individual parts by cutting the bridges formed in the channels, and lastly d) moulding a plastics material around the handle and the necks to fasten these to each other, hi the last step at least two of the bristle heads are turned so that the bristles point towards each other. The method is costly as it comprises many and complex process steps.
The object of the present invention is to provide a toothbrush for mechanical or manual use that brushes three tooth surfaces simultaneously. The toothbrush head should be self-adjusting to different tooth sizes. Furthermore, the toothbrush should be comfortable for a user to use.
The present invention provides a toothbrush device having a neck and head, wherein the head comprises at least three parts of a first plastics material, at least two of the parts having bristles attached thereto, wherein the neck has the first material as primary material and wherein the bristles on the head are parted in the longitudinal direction of the head, characterised in that the at least three parts comprise a body portion integrally connected to the neck and at least two wing portions, that the wing portions are integrally connected to the body portion via respective hinge pieces arranged in the longitudinal direction of the brush on each side of the body portion, and that the opposite wing portions, when unloaded, are angled towards each other.
Furthermore, the present invention comprises a method for the manufacture of a toothbrush device, characterised in that it comprises the following steps: - moulding, in a first plastics material, a neck, a body portion integrally connected thereto, at least two hinge pieces integrally connected to the opposite sides of the body portion in the longitudinal direction of the brush and at least two wing portions integrally connected to their respective hinge pieces; and moulding a second, elastic plastics material wholly or partly around the hinge pieces, whilst opposite wing portions form an angle relative to each other. The present invention also provides an electrically operated toothbrush with handle, neck and head, wherein the handle comprises an electrically operated motor unit, characterised in that the head comprises at least three parts of a first plastics material, at least two of the parts having bristles attached thereto, that the neck has the first material as primary material, that the at least three parts comprise a body portion integrally connected to the neck and at least two wing portions integrally connected to the body portion via respective hinge pieces of the first plastics material and arranged in the longitudinal direction of the brush on each side of the body portion, that the wing portions, when unloaded, are angled transverse to the longitudinal direction of the brush, so that opposite wing portions are angled towards each other, and that the neck is movably connectable to an end piece on the handle for movement back and forth in the longitudinal direction of the toothbrush by means of a drive motor arranged in the handle.
Preferred embodiments of the invention are set forth in the dependent claims.
The invention will now be described in more detail with reference to the attached figures, wherein
Figures Ia and Ib are, respectively a rear view and a front view of a toothbrush device according to the invention;
Figure 2a is a top view of a toothbrush head, when unloaded;
Figure 2b is a view of the same toothbrush as in Figure 2a, but when loaded;
Figures 3 a and 3b are, respectively, a front view and a side view of another embodiment of the toothbrush device according to the invention; Figures 3c and 3d are views of the same device as in Figures 3a-3b, but in a second position;
Figures 4a and 4b are, respectively a top view and a front view of parts of a device according to the invention;
Figures 5a-5c are, respectively, a front view, a side view and a rear view of a toothbrush according to the invention; and
Figure 6 is a view of another embodiment of a toothbrush according to the invention.
The device shown in Figures Ia-Ib comprises a neck 1 and a head 2. The head consists of a body portion 3 and two wing portions 4, 4' connected to the body portion via respective hinge pieces 5, 5'. in this embodiment both the body portion and the two wing portions are equipped with bristles 6, 6' and 6". In the illustrated embodiment, the brush head is equipped with one wing portion on each side of the body portion. Li another non-illustrated embodiment, it is possible, in a similar manner, to fasten several optionally interconnected wing portions to each side of the body portion.
Figures 2a and 2b are top views of a toothbrush head according to the invention, when unloaded and loaded respectively. The angle between the two opposite wing portions 4, 41 in the unloaded state is less than in the loaded state. The head is preferably so designed that the hinge pieces have a spring-like effect to ensure that the wing portions 4, 4' return to the starting position, the unloaded state, as soon as the load ceases. There is no connection between the hinge pieces 5, 51, and therefore each wing portion adjusts individually to the load that is applied. The length of the different bristle portions 6, 6' and 6" is preferably such that when the brush is loaded in that a tooth is passed into the space 11, the bristles 6, 61 will brush the side surfaces of the tooth whilst the bristles 6" brush the masticating surface. Thus, the tooth is brushed on three sides at the same time. Because of the elastic hinging of the wing portions 4, 4' to the body portion 3, the brush will automatically adjust to the size of the teeth to be cleaned. It is preferably possible to subject the brush head to such a load that the angle between the wing portions 4, 4' is 180°. This is particularly advantageous in the manufacture of the brush, as the bristles 6, 6' and 6" can be inserted into the wing portions 4, 41 and the body portion 3 whilst the wing portions 4, 4' and the body portion 3 have such a planar configuration.
Figures 3a - 3d are views of a toothbrush head 2. Figures 3a and 3c are front views of the brush, whilst Figures 3b and 3d are side views thereof. The brush neck is telescopically movable in a sleeve 7 for movement back and forth in the longitudinal direction of the brush. The figure shows the extreme position in this movement pattern. hi Figures 3 a and 3b, the distance B between the head 2 and the sleeve 7 is substantially greater than in Figures 3c and 3d. hi the illustrated embodiment, the wing portions 4, 4' are equipped with bristles 6, 6'. The length of the bristles is preferably adapted so that the brush can brush at least two tooth surfaces at the same time.
Figure 4 is a view of a possible embodiment of the neck 1 , the body portion 3, the wing portions 4, 4' and the hinge pieces 15, 15'. Figure 4a is a top view of the head whilst Figure 4b is a front view thereof, hi this embodiment all the illustrated parts are moulded in a first plastics material. In a preferred embodiment, the illustrated hinge pieces 15, 15' of a first plastics material will be wholly or partly surrounded by a second, elastic plastics material as shown in Fig. 1. Figure 4 illustrates a possible design of the part of the hinge pieces that can be made of the first plastics material. The hinge pieces 15, 15' may be configured in any suitable manner. Figures 5a - 5c are, respectively, a front view, a side view and a rear view of the device according to the invention with neck 1 and head 2. The neck is detachably connected to an end piece 9 on a handle 8. Furthermore, the neck 1 and the end piece 9 are surrounded by a sleeve 7 detachably connected to the handle 8. The handle 8 comprises a motor unit, not shown, which can cause the end piece 9 to move in and out of the handle 8. This motion is transmitted to the neck 1 which then will move in and out of the sleeve 7. Consequently, the head 2 moves back and forth in the longitudinal direction of the brush. The motion is started and stopped via a switch 10.
Figure 6 shows another possible embodiment of a toothbrush comprising a device according to the invention. In this case, a head 2 and a neck 1 are integrally connected to a handle 11. Preferably, the handle has the first plastics material as primary material. Furthermore, parts of the handle 11 may be made of the second plastics material. This is not shown in the drawing.
The device according to the invention can be made by first moulding the neck 1, body portion 3, wing portions 4, 4' and optionally parts of the hinge pieces 15, 15' in a first plastics material. Thus, a device as shown in Figure 4 is provided, optionally without hinge pieces 15, 15'. The wing portions 4, 4' may either be moulded at an angle to each other as shown in the figure, or the device can be moulded in one plane, that is to say without an angle between the wing portions, and the wing portions 4, 4' are then angled after moulding. It is also possible to first mould three separate parts consisting of two separate wing portions 4, 4' and a common neck and body portion 1, 3. A second plastics material is subsequently moulded between the body portion 3 and the wing portions 4, 41 so that this second material constitutes at least a part of the hinge pieces. The second plastics material preferably surrounds the hinge pieces 15, 15'. A device according to the invention is made most preferably by a so-called two-component moulding process.
