Abstract

Tooth brush, comprising a body defined by a handle portion (10) and a head portion (20) having a front face, into which is affixed a basic plate (31) incorporating a bristle assembly (30) injected in plastic material.

Description

Toothbrush

The present invention relates to a kind of toothbrush, wherein the bristle member adopts suitable sheet of semirigid plastic material, the injection moulding integrally of for example low-density polyurethane to make.

Its bristle is arranged is with some kinds of injection molded Tooth-brush structures of suitable material monolithic known in the art, and shape is made for and these parts of brushing teeth is had carry out the required anatomic characteristic of proper operation, pliability and flexibility characteristics.In a kind of known structure, toothbrush has the bristle that brush holder, brush and integral molded plastic form, as described in document FR2.559.361, US3.302.230, BR MU 6700603, BR MU5601232 and PCT/EP98/03696.

Make and the operation of nylon bruss pieces is installed and obtains that a kind of structure is very simple, the low-down toothbrush of cost although this organization plan can omit in the traditional toothbrush, but because the material requirements of the remainder of the toothbrush that is constituted to bristle and by brush and brush holder is different, monoblock type injection moulding scheme is very inconvenient.These different requirements have seriously been limited the conceptual design of toothbrush, and make each parts appearance design that constitutes brush holder, brush and bristle depend on the operation requirement of other parts.

Another kind of also adopt the integral molded plastic bristle but representative the more another kind of organization plan of conceptual design be that its head toothbrushes and bristle are linked to be overall structure, usually brush are coupled on the brush holder and just can use (as described in document DE 2728672).Though the available material different with bristle of certain part made on the brush holder, this scheme interdepends the material of bristle and head toothbrushes, and this head toothbrushes makes more greatly and is attached on the handle will cooperate with fixture.This makes that the flexibility of conceptual design is still very little.

In the art, also have some by the toothbrush that the injection moulding body is made, comprise all-in-one-piece brush holder and brush, brush has adapting device, holding and to lock a bare bones, and this bare bones has generally the bristle tuft of the common quantity of being made by nylon.Though this can make the material of bristle and toothbrush body separate, this suggested among the BRPI 8900425 solution is also inconvenient, promptly needs and makes and bristle tuft is fixed to the relevant all operations of bare bones.Therefore, even can select the composition of toothbrush body material and bristle tuft neatly, but the cost of these toothbrushes is quite high.

Catalogue of the present invention be to provide a kind of toothbrush, this toothbrush is made easily, cost is low, and versatility is very strong when determining to make the material of body and bristle tuft.

Of the present invention one more specifically purpose be to provide a kind of aforesaid toothbrush, this toothbrush has the bristle made with the injection-moulded plastic material and body (this body is by brush holder and be used to support that the brush of bristle constitutes).

Toothbrush of the present invention comprises a body of being made up of brush holder part and brushhead portion, and this body has a front, is consolidated with a substrate on this front, on this substrate combination integrally the injection molded many bristles of usefulness plastic material.

Toothbrush of the present invention comprises the body that is made of brush holder part and brushhead portion, and this body tool is used to hold the device with a fixed substrate, integrally is combined with a bristle member on this substrate.

Said structure can be made into a kind of like this toothbrush, its body available energy that is made of the brush holder part and the brushhead branch of monoblock type or non-integral type satisfies the plastic material injection moulding of its function or otherwise makes, and it is irrelevant with the used plastic material of injection moulding brush member, bristle can be attached on the substrate, and substrate is bonded to the brushhead portion of toothbrush body subsequently.

Below with reference to the accompanying drawings to describe the present invention, wherein:

Fig. 1 is the plane that is used for a kind of first half that may embodiment of toothbrush body of the present invention, and its bristle member is not mounted thereon as yet;

Fig. 2 is the central longitdinal cross-section diagram of toothbrush body of the present invention, there is shown before its bristle member is fixed to the brushhead portion of toothbrush body, be in a relevant bristle member that decomposes the position; And

Fig. 3 is and the similar view of Fig. 2 that just the bristle member has been bonded to the brushhead portion of toothbrush body.

As shown in drawings, toothbrush of the present invention is made of a body C with a brush holder part 10 and a brushhead portion 20, and they are injection molded into one with plastic material usually, and the shape of described toothbrush is made for structure, function and the characteristics attractive in appearance that satisfy the toothbrush conceptual design.

Though the body C shown in the figure is all-in-one-piece, but should understand, brush holder part 10 can be made for different parts with brushhead portion 20, when toothbrush is installed they is for good and all linked together, and perhaps can by the user it be cooperatively interacted when the user need begin to brush teeth.

In accordance with the embodiments illustrated, brushhead portion 20 has a flat front, and a groove 21 is arranged on it, the periphery of the relative brushhead portion 20 of this groove only keeps a bit of distance, and the bottom of described groove 21 also has a hole 22, as shown in the figure, the back of brushhead portion 20 is led in this hole, and promptly it is a through hole.

In order to make shaping and compounding practice convenient, groove 21 is circular for ellipse hole 22.

Shown in Fig. 2 and 3, in groove 21, closely be combined with a substrate 31, the front portion of this substrate integrally is combined with a bristle member 30, and this bristle member is injection molded by plastic material.In illustrated embodiment, substrate 31 is combined with a pin 32, this pin be generally circular and from the substrate 31 side opposite with bristle member 30 stretch out, and it is of a size of in the hole 22 that can be engaged in brushhead portion 20 when substrate 31 is engaged in the groove 21 (as shown in Figure 3).

Be to be understood that, substrate 21 be engaged in can realize in the groove 21 between two parts can not break away from fixing, perhaps make a departing assembly, the latter can change bristle member 30 at any time and according to user's needs, perhaps can temporarily separate so that the cleaning auxiliary section from body C simply.

A kind ofly bristle member 30 cooperated and be fixed to embodiment on the brushhead portion 20 though only described in this article, should be understood that can adopt many different structures guarantee to realize a kind of can or cannot by the user take apart firm fixing.
