Definitions
- the invention relates to a brush, in particular a toothbrush, with an upper part and a lower part, which are connected to one another via a hinge, wherein in the lower part a storage space for a liquid or pasty agent, in particular toothpaste, and the brush head are arranged on the upper part and wherein between
- Pantry and brush head extends a channel.
- the invention is therefore based on the object to provide such a toothbrush, which consists of a few parts and therefore is easier and cheaper to produce.
- a device is arranged in the channel, which prevents or prevents flow of the agent from the brush head to the storage space, that the upper part and the lower part have rigid wall sections, via the joint are interconnected and that between the rigid wall portions, an elastic wall portion is arranged, which has a wall portion of the
- a preferred embodiment of the invention is characterized in that the storage space on the side opposite the upper part is limited by a bottom part movable only towards the upper part and that the channel is always open from the storage space to the brush head and that in the channel a cross-sectional constriction is provided, which one
- the pumping process carried out by pivoting the upper part relative to the lower part.
- pivoting the upper part relative to the lower part of the storage space is reduced in the region of the elastic wall portion, so that the agent is pressed through the channel to the brush head.
- volume compensation be created, otherwise the agent would be sucked back out of the channel.
- the upper part and the lower part have rigid wall sections, which are connected to one another via the joint and between which the elastic wall section is arranged.
- the rigid wall sections and the hinge are formed from a one-piece part. They can therefore be produced in a single injection process, wherein the joint can be carried out in a known per se, for example as a film hinge.
- the channel is bounded directly by the rigid wall sections and the elastic wall section. That is, there are no further protective or separating layers between the rigid wall sections and the elastic wall section, which further simplifies the production.
- the lower part and the upper part can be formed with their rigid portions of one-piece parts and limit the reservoir or the channel.
- the entire brush apart from the movable bottom part and the bristles on the brush head, can be made in a simple embodiment of a single part, on which only the elastic wall portion must be attached, which can be done by a second injection process in a simple manner.
- the width of the joint is among other things of the diameters of the upper part and the lower part and their length and, of course, also dependent on the desired stability of the joint against lateral kinking.
- width of the joint is between 1/6 and 1/2, preferably about 1/3, of the diameter of the lower part and / or if the width of the joint between 1/5 and 2/3, preferably about 1/2, of
- Diameter of the upper part is. These dimensions ensure in the usual dimensions of such brushes sufficient stability of the joint and functionality of the brush.
- FIG. 3 shows the middle region of the brush in the region of the joint from the side
- FIG. 4 shows the middle region of the brush in the region of the joint from above
- Fig. 5 shows the brush while it is being bent for a pumping operation; and Fig. 6 shows a section through the brush while it is pumping
- the brush according to the invention has an upper part 1 and a lower part 2, which are connected to each other via a hinge 3 on.
- the upper part 1 and the lower part 2 are made of a hard and rigid material, such as polypropylene, and preferably with the joint 3, that in the manner of a
- Film hinge can be made in one piece.
- a brush head 4 with bristles 5 At the upper end of the upper part 1 is a brush head 4 with bristles 5, the number and length of each desired application depends.
- the lower part 2 is cylindrical and encloses a storage space 6 which is delimited on the side opposite the upper part 1 by a bottom part or piston 7.
- the bottom part 7 is ideally a sliding on the inner surface 8 of the wall of the lower part 2, which is movable for example by suitably shaped ribs on the inner surface 8 and / or claws 9 or the like only in the direction of arrow 10 to the upper part 1, whereas a movement in the other direction is prevented by the ribs and / or claws 9.
- the upper part 1 delimits a brush head 4 towards narrowing channel 1 1, which extends from the storage space 6 to the brush head 4 and at the end 18 has its smallest cross-section.
- an extension in the form of an elastic tube 12 can be arranged at the end of the channel 11. on the one hand, in order to adjust the flow resistance in addition to the channel 11 in addition, on the other hand, in order to promote the agent further towards the end of the bristles 5 can.
- the tube can also perform a similar function as a valve if it is elastic enough to fold together.
- an elastic wall portion 13 is arranged in the region of the joint 3, on the one hand to the edges 14, 15 of the rigid wall sections 16 and 17 of the upper part 1 and the lower part 2 and on the other hand to the joint 13 connects.
- Wall section 13 which consists for example of a thermoplastic elastomer, can be injection-molded directly onto the wall sections 16 and 17 by means of a per se known injection molding method and thus be permanently connected thereto.
- the upper part 1 is bent relative to the lower part 2, as shown in Fig. 5 and 6.
- the upper part 1 buckles at the joint 3 with respect to the lower part 2 and a part of the elastic wall portion 13 and, to a certain extent, also the bending-resistant portion 16 adjoining the edge 14 are pressed somewhat into the storage space 6. Since the bottom part 7 can not dodge down, the agent through the channel 11 and the tube 12 to the or
- the bending-resistant wall section of the upper part 1 and the lower part 2 adjoining the joint 3 are offset by approximately the wall thickness of the wall sections relative to each other.
- This arrangement improves the pumping action of the brush according to the invention.
- the wall sections are offset even further or less than shown in the drawings to each other.
- the wall sections in the area of the joint 3 can be aligned with one another.
- the flow resistance of the channel 11 is determined primarily by the flow cross-section in the region of the brush head 4. It is of course possible, alternatively or additionally at other points of the channel 1 1 measures, such as a valve, enforce, which the
- the channel 11 can be filled by pressing on the bottom part 7 until the backflow resistance in the channel 11 is so great that not the agent sucked back from the channel 1 but the bottom part 7 sucked in the direction of the arrow becomes.
