Such a job device is for example from the DE 197 30 454 A1
known. In this known applicator, the applicator consists of a liquid capillary promoting material.
An applicator with a capillary applicator, for example, from the DE 201 09 542 U1
In order to operate ie to open the resilient valve device of such a known applicator, it is necessary that the capillary applicator has sufficient hardness and dimensional stability. This requirement is the demand for a capillary promoting applicator member, which usually has a correspondingly low hardness, contrary. A soft application member is hardly suitable for the actuation of the resilient valve device, because deformations of the applicator member at its front-side application end portion by the repeated pumping of the valve device are hardly or not to avoid. However, such deformations of the applicator end portion of the applicator affect the applicator properties of an applicator accordingly. That's why the beats DE 20 2004 020 008 U1
an applicator of the type mentioned above, wherein the applicator member has two Auftragorganbereiche, each extending from the voltage applied to the resilient valve means inner end of the applicator member to the front-side application end, said an applicator organ soft and capillary promotional and with an application surface for the liquid Application medium is formed, and of which the second Auftragorganbereich dimensionally stable hard and is provided for actuating the valve device. Both the hard second applicator region and the soft, capillary-promoting first applicator region can each consist of capillary fiber material, the capillarity of the central first applicator region being large compared to the capillarity of the second applicator region. Even with this latter applicator, the applicator thus consists of capillary promotional materials.
Invention is the object of an applicator of the above
mentioned type to be applied with the dosed liquids
and wherein the applicator has excellent dimensional stability and creep resistance.
The object is achieved by the

4 a view of the applicator in the direction of arrow IV in 1 ,
1 shows a longitudinal section of an embodiment of the applicator 10 whose case 12 is drawn off. The housing 12 serves as storage for a liquid 14 , The liquid 14 is used to remove stains.
The housing 12 has a housing opening 16 , on which a resilient valve device 18 is provided. Such a resilient valve device 18 is known per se, so that it need not be described in detail.
At the housing opening 16 of the housing 12 is a housing front part 20 attached, from which an applicator 22 of the applicator 10 for the liquid 14 protrudes. The applicator 22 also serves to actuate the valve device 18 ,
The applicator 22 consists of a dense, ie non-capillary promotional, dimensionally stable hard material, it is with a Auftragendabschnitt 24 (see for example also 3 ) and formed with a pin portion axially aligned with the applicator end portion. The pen section 26 of the applicator 22 lies with its inner end 28 on the resilient valve device 18 at. Will on the applicator 22 exerted a pressure, so with the help of the applicator 22 the valve device 18 opened, after which out of the case 12 a certain quantity of liquid 14 to the order end section 24 of the applicator 22 can be issued. For this purpose extend along the pin section 26 of the applicator 22 two diametrically opposed conveyor troughs 30 (see also the 2 . 3 and 4 ) to the order end section 24 of the applicator 22 and into these.
Like from the 1 and 3 can be seen possesses the Auftragendabschnitt 24 a cross-sectional area that is greater than the cross-sectional area of the pin portion 26 ,
The housing front part 20 is with a guide section 30 designed to guide the pin portion 26 of the applicator 22 serves. The guide section 30 is with ribs 32 (please refer 2 ) formed in the conveyor troughs 30 of the applicator 22 into it are. In this way, an unwanted twist of the applicator 22 relative to the front housing part 20 and thus relative to the housing 12 of the applicator 10 prevented. For the same purpose, it is helpful if the leadership section 31 of the front housing part 20 with a leadership rib 34 is formed in an associated guide groove 36 of the pin section 26 of the applicator 22 is in (see 2 ). Of course, the applicator 22 in relation to the housing 12 of the applicator 10 also be rotatable about its central longitudinal axis.
While the conveyor troughs 30 from the inside end 28 until the order end section 24 of the applicator 22 extend, the guide groove extends 36 only along the pin section 26 and ends at the order end section 24 of the applicator 22 ,
How out 1 it can be seen, is the front housing part 20 to the guide section 31 axially outside adjacent to a recess 38 formed in the pressed state of the applicator 22 - to dispense liquid 14 out of the case 12 of the applicator 10 - For partial recording of Auftragendabschnittes 24 of the applicator 22 is provided. Even in the pressed state of the applicator 22 is the order end section 24 So from the front housing part 20 in front.
At the guide section 31 adjacent to the inside is the front housing part 20 with a capillary liquid leakage protection 40 material integral or with a leakage protection 40 Mistake.
The pen section 26 of the applicator 22 has, for example, such an axial length dimension that the applicator 22 in the non-depressed normal storage condition of the applicator 10 with a to the order end section 24 subsequent front section 42 of the pin section 26 from the housing advantage 20 protrudes.
The order end section 24 of the commissioning body 22 has a cylindrical surface 44 and two diametrically opposite inclined surfaces 46 on. The two inclined surfaces 46 close an acute angle with each other 48 and form a common rounded leading edge 50 , The rounded front edge 50 is against the longitudinal ie axis direction of the applicator 22 or against the longitudinal ie axis direction of the applicator 10 inclined as the 1 clarified.
The conveyor troughs 30 of the applicator 22 extend into the inclined surfaces 46 of the order end section 24 into it.
4 clarifies that the order end section 24 of the applicator 22 has an elliptical cross-sectional area, the leading edge 50 of the order end section 24 is provided congruent with the long axis of the elliptical cross-sectional area.
