Definitions
- the invention relates to a brush, in particular toothbrush, the one end to a container with a metering pump can be fastened and a brush-container combination with such a brush and a container with a metering pump.
- Toothbrush Container Combinations For pumping through the relatively long outlet channel in the toothbrush and by the viscous Toothpaste a relatively high force to operate the Pump is required, especially for weaker persons difficult or impossible, toothpaste from the tube to the brush head to pump or perform this precisely metered.
- the invention is therefore based on the object, a brush and a To provide brush container combination, which the largely avoid the mentioned disadvantages.
- the invention makes use of the fact that through the brush, in particular a toothbrush, a relatively long lever arm available is placed, with the pumping movement relative to the container can be performed, wherein by the contact surface on the brush the metering pump is actuated on the container.
- a relatively long lever arm on the brush is the force required to perform the Pumping movement significantly reduced and when the point of attack on the end of the brush is done, is also a relatively long Kraftweg available that allows precise dosing.
- the present invention is not limited to toothbrushes and toothpaste container is limited, but also for Any other purposes can be used, with only for example, e.g. Brushes for applying shoe polish or small brushes for applying mascara are mentioned. It it will be understood that instead of the brush head, as e.g. at Toothbrushes use, including any other facilities for applying the liquid or pasty agent, e.g. thrush or spatula-shaped devices can be used.
- a toothbrush 18 is shown in longitudinal section, at one end a brush head 17 and a shaft of the Toothbrush 18 penetrating in the longitudinal direction and in the area of Brush head 17 opening channel 11 has.
- the toothbrush 18 with an approximately cylindrical toothpaste container 1 connected.
- the container 1 indicates his the toothbrush 18 associated end a neck 14 with a Output opening 5 on.
- the toothbrush 18 points in extension the channel 11 at the end 9 a neck 14 correspondingly shaped Recess and an internal thread and can thus on the neck 14th be screwed on.
- Such a screw connection allows a simple attachment and removal of the toothbrush 18 on the container 1, so that the container 1 and the toothbrush 18, if necessary, easily can be exchanged.
- Toothbrush 18 and the container 1 are separated again are also other forms of the compound, such. a bounce connection or sticking of toothbrush 18 and container 1 conceivable.
- the container 1 has a Membrane pump on, by a dome 13, on which also the neck 14 is arranged, as well as a distance from the dome 13 partition 4 is formed.
- the dome 13 connects to an approximately cylindrical wall 22 of the cylindrical container 1 and is elastically deformable executed so that he by a pumping motion with the help of the toothbrush 18 can be elastically deformed, as in the episode yet will be described.
- the partition 4 divides the interior in the container 1 in a Pump chamber 12 between Dom 13 and partition 4 and a storage space 7 between the partition 4 and a not shown in the drawing Bottom of the container 1.
- a valve arranged, only in the direction of the storage space 7 to the pump room 12th can be flowed through.
- the toothbrush 18 In order to carry out a pumping operation, the toothbrush 18 a contact surface 23 which in the region of the end 9 and on the same side as the brush head 17 is arranged on the toothbrush 18 is. If the toothbrush in the direction of arrow 20 relative to Container 1 pivots, deforms the dome 13 in the region of Neck 14 elastic and the contact surface 23 additionally pushes the Dom 13 inside, so that the pump chamber 12 is reduced. Since that Valve 10 is not flowed through to the storage space 7 through toothpaste can be, but at the beginning of the pumping movement immediately in the direction of the arrow 6 closes, toothpaste is passed through the dispensing opening 5 and the channel 11 is pumped in the direction of arrow 19 to the brush head 17.
- Valve 16 e.g. in the form of a rubber plate, be provided that after completion of the squeezing process or after cleaning the Brush head 17 sealingly applies to the output port 15 and this closes.
- a reliable pumping function can be ensured so that the Medium can not flow back in the channel 11.
- a membrane pump can of course also any other shape a metering pump, e.g. a piston pump, used the piston would be actuated by the contact surface 23.
- the toothbrush 18 in the area of their end 9 a conical broadening 24 on their side facing the container 1 forms a support surface 25.
- a corresponding support surface 27 provided with the support surface 25 cooperates with the toothbrush 18. Since the cathedral 13 in the area of Transition 26 has a high deformation resistance is prevents the toothbrush 18 in use against the direction of the arrow 20 is pivoted. Since the support surface 27 on the dome 13 rotationally symmetrical is and the support surface 25 also rotationally symmetrical is and is interrupted only by the support surface 23, the toothbrush 18 is also good on the side next to the support surface 23 supported, so that a lateral tilting or pivoting of the Toothbrush 18 is avoided.
- the toothbrush 18 it would also be conceivable for the toothbrush 18 to be designed in this way is that no separately provided support surface during the Pumping movement on the dome 13 is applied, as already by the elastic Deformation of the dome 13 in the area around the neck 14 during the Pumping a pumping effect occurs.
- the Connecting surface between the end 9 of the toothbrush 18 and the neck 14 in the form of the thread 21 the contact surface, wherein also in In this case, the pivotability of the toothbrush 18 according to the invention relative to the container 1, i. the use of the toothbrush 18 as Pump lever, is realized.
- the toothbrush 18 via a joint is connected to the container 1, so that the container 1 through the Pivoting movement of the toothbrush 18 is not elastically deformed and over the contact surface a pump, e.g. a piston pump or Diaphragm pump, is actuated.
- a pump e.g. a piston pump or Diaphragm pump
- the bottom of the container is ideally a sliding on the inner surface 27 of the container wall 22 Part formed by suitably shaped ribs on the inner surface 27 and / or claws on the ground only in the direction of arrow 8 to the partition 4 towards, whereas a movement in the other direction by the ribs and / or claws is prevented, and by sucking toothpaste from the storage space 7 in the pump chamber 12 automatically is retraced.
