Description

The invention relates to an application device, with a storage container for a liquid application medium, with an application element which capillary conveys the application medium, which extends through a screw mouthpiece and protrudes with an application section from the screw mouthpiece, and with an application element on the screw mouthpiece attachable closure cap, which is intended for tightly closing the applicator when not in use.

Such applicators are known in a variety of different embodiments.

For example, describes the DE 10 2008 050 066 B4 an application device of the type mentioned at the beginning, with a storage container for a liquid application medium, with a valve device provided for closing the storage container and with an application element which capillary conveys the application medium and which protrudes with an application section from the screw mouthpiece of the application device. The valve device can be opened by means of the application element. In this known applicator, the applicator element has a central, capillary-promoting, soft applicator element and a dimensionally stable hard sleeve element surrounding this applicator element, which protrudes at the front with a shoulder from the screw mouthpiece of the applicator and the central applicator element with an applicator section over the shoulder protrudes from the sleeve element. To open the valve device, a dimensionally stable, hard actuating element is provided to rest on the shoulder of the sleeve element.

From the DE 10 2011 009 495 B4 an application device is known with a storage container provided for an application liquid, at the housing opening of which a resilient valve device is provided. A front part of the housing is provided at the housing opening, from which an applicator for the application liquid protrudes. The applicator is arranged interchangeably in the front part of the housing and is intended for opening the valve device. The valve device is assigned a holding device, by means of which the applicator is captively arranged in the applicator. For this purpose, the applicator is designed with an undercut on its inside end section and the holding device is designed with a holding area that engages resiliently in the undercut.

The DE 10 2012 013 562 B4 describes an application device with a storage container for a liquid application medium and with an application element that capillary conveys the application medium, which is guided through a screw mouthpiece screwed to the storage container and, when applied, protrudes from the screw mouthpiece with an application section. A valve device is provided in the storage container. A closure cap is provided for tightly closing the applicator in its non-use state, which has an actuating element. When the applicator is not in use, the closure cap presses with its actuating element against the application section of the applicator, so that the valve device is opened in the non-use state against the spring force of its valve spring element by means of the applicator.

The DE 10 2015 009 743 B4 describes an application device with a storage container for a liquid application medium. The storage container is suitable for exerting pressure on the application medium. A valve device is provided at the housing opening of the storage container, which has a valve plunger in a valve housing, which can be axially movable against the spring force of a valve spring element provided in the valve housing and the valve device can be opened by means of a dimensionally stable capillary application element protruding from the screw mouthpiece of the applicator is. The valve plunger is designed with a through channel in which a resilient channel valve device is provided, the resilient channel valve device being opened by exerting pressure on the storage container of the applicator.

From the DE 10 2017 011 173 B4 an adapter for an applicator is known. The applicator has a storage container for a liquid application medium with a device mouthpiece, from which a dimensionally stable device applicator element protrudes that capillary conveys the application medium. A valve device that can be opened by means of the application element is provided in the storage container. The adapter is intended for the axially limited movable mounting of the applicator; it has an adapter sleeve with an adapter mouthpiece, from which a capillary-promoting adapter applicator element protrudes axially immovably and is adjacent to the device applicator element. The adapter mouthpiece is designed with a guide recess in which the device mouthpiece can be moved in a linearly limited manner with a guide section.

With the known applicators, which are designed, for example, as so-called fiber pens or as so-called valve markers, it makes sense from an environmental point of view if the storage container of the respective applicator can be refilled with liquid application medium if necessary. To refill the fiber pens, it is necessary to unscrew the screw mouthpiece from the storage container in order to release the memory The cher container can then be filled with liquid application medium. However, it cannot be reliably prevented that undesirable contamination occurs, for example on the fingers of the person carrying out the filling process. The same applies particularly to valve markers if they need to be refilled with liquid application medium if necessary. What makes valve markers even more difficult is that the valve device has to be removed from the storage container before refilling. In particular, residues of the application medium can lead to undesirable contamination, particularly on the fingers of the person carrying out the refilling.

Knowing these circumstances, the invention is based on the object of creating an application device of the type mentioned at the outset, in which the storage container of the application device can be refilled cleanly manually using structurally simple means, without the risk of unwanted contamination, for example on the fingers of a refilling person person, is possible.

This object is achieved according to the invention by the features of claim 1, i.e. solved in that the screw mouthpiece screwed to the open end section of the storage container is designed on the outside and the closure cap on the inside with shaped elements for a twist-proof connection of the screw mouthpiece to the closure cap.

The applicator device according to the invention has the advantage that the screw mouthpiece can be unscrewed from the open end of the storage container together with the closure cap temporarily tightly attached to it, so that when the storage container is refilled with liquid application medium, there is no unwanted contact with the screw from the screw. Mouthpiece protruding, capillary-promoting application element and thus unwanted contamination, for example on the fingers of a person carrying out the refilling, is easily avoided.

It has proven to be advantageous if, in the applicator according to the invention, the screw mouthpiece and the closure cap are each designed with axially oriented longitudinal ribs which are spaced apart from one another in the circumferential direction and which form shaped elements. The longitudinal ribs of the screw mouthpiece engage in the longitudinal recesses of the closure cap - and vice versa - in order to achieve a twist-proof connection of the screw mouthpiece to the closure cap.

It is preferred if the distance between the longitudinal ribs of the screw-nut element and the longitudinal ribs of the closure cap is each greater than their thickness dimension. This results in the advantage that when the closure cap is placed on the screw mouthpiece, the probability that the longitudinal ribs of the screw mouthpiece and the longitudinal ribs of the closure cap come into contact with one another is negligibly low, or an unlikely possible contact can occur very easily a small rotation of the cap relative to the screw mouthpiece can be canceled out.

For the same purpose, to be able to attach the cap easily and securely to the screw mouthpiece in a temporary seal, it is useful if the longitudinal ribs of the screw nut element are designed with inclined surfaces that taper towards the outside.

In the application device according to the invention, a capillary storage body for the liquid application medium can be provided in the storage container, on which the capillary-promoting application element, which extends immovably through the screw mouthpiece, rests. This is a so-called fiber pen, as described above. Another possibility according to the invention is that a valve device is provided in the open end section of the storage container, which can be opened by means of the capillary-promoting application element, which extends axially movably through the screw mouthpiece, and is positively connected to the screw mouthpiece. This is a so-called valve marker, as described above.

In order to reliably achieve, in an applicator according to the invention of the last-mentioned type, that for refilling the emptied storage container with liquid application medium, together with the screw mouthpiece, the valve device provided in the open end section of the storage container, with the help of the closure cap from the storage container Container is removed, it is preferred if the valve device is designed with a collar and the screw mouthpiece with a groove into which the collar protrudes in a form-fitting manner. As a result, the closure cap with the screw mouthpiece and the valve device form a unit that can be manipulated by means of the closure cap.

Further details, features and advantages can be found in the following description in conjunction with the accompanying drawings.

How out 2 As can be seen, the open end section 18 of the storage container 12 is formed with an external thread section 20. A capillary storage body 22 for liquid application medium is provided in the storage container 12.

A capillary-promoting application element 24 extends immovably through the screw mouthpiece 14. The application element 24 is fluidly connected to the storage body 22 by means of its rear contact section 26 in order to transport the application medium through the application element 24 to its front application section 28, which protrudes from the screw mouthpiece 14.

The Schaub mouthpiece 14 has a mounting collar 30, which is formed with an internally threaded section 32 and which is screwed to the externally threaded section 20 of the storage container 12.

The screw mouthpiece 14 screwed onto the open end section 18 of the storage container 12 is formed on the outside with shaped elements 33 and the closure cap 16 is formed on the inside with shaped elements 33 for the rotation-proof connection of the screw mouthpiece 14 to the closure cap 16, as shown 4 is visible. The shaped elements 33 are designed as longitudinal ribs 34, 36, which are spaced apart from one another in the circumferential direction. The distance “a” between the longitudinal ribs 34 of the screw-nut element 14 is larger than their thickness dimensions “d”. The same applies to the longitudinal ribs of the closure cap 16.

How out 3 As can be seen, the longitudinal ribs 34 of the screw-nut element 14 are formed with outwardly tapered inclined surfaces 38.

The same details are in the 1 to 4 each designated with the same reference numbers, so that it is unnecessary to describe all the details in detail in connection with these figures.

The valve device 40 can be opened by means of a capillary-promoting application member 24, which extends axially movably through the screw mouthpiece in order to be able to open the valve device 40. For this purpose, the rear section 26 of the application element 24 is mechanically connected to the valve device 40. The application section 28 of the application element 24 protrudes from the screw mouthpiece 14.

The valve device 40 is positively connected to the screw mouthpiece 14, as shown in detail IX in 7 is clearly visible. For this purpose, the valve device 40 is designed with a circumferential collar 42 and the screw mouthpiece 14 with a circumferential groove 44 into which the collar 42 protrudes. When the closure cap 16 is unscrewed from the storage container 12 to refill the application device 10 with liquid application medium. The entire unit, consisting of the closure cap 16, the screw mouthpiece 14 and the valve device 40, is unscrewed from the storage container 12, so that unwanted contamination on the fingers of a person refilling the applicator 10 is advantageously avoided. After filling the storage container 12, the unit, consisting of the closure cap 16, the screw mouthpiece 14 and the valve device 40, can then be screwed back onto the storage container 12.

The same details are also in the 5 to 9 each with the same reference numbers as in the 1 to 4 so that it is unnecessary to describe all the details in detail in connection with all the figures.
