Description

The invention "relates to an application device from KosDietica and other liquid, paste or colloidal agents.

It is a device which has a container receiving the agent, from which it can be fed to the application member by means of a thrust piston Piston rod with the help of a Breh screw mechanism is axially displaceable.

In such a device it is important that the application agent is fed to the application member so that it is of this can be applied evenly to the area to be treated and, if necessary, distributed over it.

It is also important that such a device be very reliable and, for this purpose, of a proportionate nature there is a small number of reliably cooperating parts. These parts should be simple and inexpensive be producible. Furthermore, it is important that this device, which is mostly used by women, is easy to use handle is.

A device of the type specified at the beginning, which is characterized by: that the device jacket is designed in the middle area as a storage container for the agent, in the front area a the Has means in the application member axially introducing injection member and in the rear area to the rear Refilling the container with removable feed mechanism records.

Because of the condition that the applicator applied the agent evenly to the smile to be treated and can be distributed thereon, an essential feature of the invention is that the insect organ is a is axially introduced into the application member hollow needle, which is integral with its holding member and as a result can be produced easily and cheaply by injection molding from plastic.

This holding member is designed as a sleeve which tapers conically towards the front and which is located therein Another important feature of the invention, on the one hand between itself and a front head piece of the jacket the holder of the applicator, e.g. the clamp of a brush, and on the other hand with an outer one Annular bead engages in an inner annular groove of the jacket and in this way reliably in the position of use is fixed.

We already mentioned, represents the middle part of the device casing itself represents the storage container for the agent.

The training is made so that the longitudinally movable in it Thrust piston removed with the feed mechanism housed in the rear area of the device casing can be so that the reservoir can be refilled from behind again and again.

There is a particularly advantageous embodiment in that the jacket has a profiled, e.g. hexagonal inner wall in the rear area and in it the piston

it rod by means of a cross-section adapted link / longitudinal

is displaceably guided.

-A-

With this piston rod, i.e. with its internal thread acts a threaded rod together, which by means of a rear Handle is rotatable, which in turn engages by means of an annular bead in an inner annular groove of the jacket and thereby to One is set in the usage position and the other is secured against longitudinal displacement.

Further features, introductions, and advantages of the invention result from the following description of preferred exemplary embodiments and with reference to the drawing. Here show:

Pig. 1: a longitudinal section through a device according to the invention;

3? Ig. 2: a partial longitudinal section through the device casing;

3: a section according to IH-III;

Pig. 4: a section according to IV-IV;

Pig. 5: the piston rod in view;

Pig. 6: a view in the direction of the arrow X;

Pig. 7: a view of the threaded rod with the rotary knob

As Figures 1 and 2 show dao device has a casing 1, which, as already mentioned, in the central region (B) as a stock V ^ Jiälters 2 ^is for dan cosmetic products or the like. A ^{L) il} '^ * 309,824 / 051 1

In the front area (A) the container 1 goes into the head piece 3 over, which tapers conically towards the front. In it sits the application member 4, in the embodiment shown, a brush. This becomes the cosmetic product fed through the hollow needle 5, which extends axially forward into the center of the brush, so that the agent emerges in the brush axis from the hollow needle 5 and as a result evenly with the brush on the surface in question can be applied. The hollow needle is in one piece with its holder 6, which is a conical shape according to | is the forward running sleeve, which is advantageously made in one piece with the hollow needle 5, preferably made of plastic by injection molding.

The sleeve 6 is fixed in the head piece 3 of the jacket 1 in that its radially outwardly projecting annular bead engages in a corresponding inner-side annular groove 8 of the head piece 3. As a result , it is both fixed in the position of use and secured against longitudinal displacement.

The holder of the application member 4 in the exemplary embodiment shows the brush clamp 9 t with a press fit, such as Mg. 1 represents, between the head piece 3 and the sleeve 6.

30982Λ / 0511/6

In the rear area (G) of the device casing 1 is the feed mechanism housed. This has the piston 9, which is longitudinally displaceable in the storage container 2 and below it Pressure, the cosmetic agent or the like. Is fed to the application member.

shows The device jacket has how! "Fig. 4 / a profiled, e.g. Hexagonal inner wall 10. The cross-sectionally adapted miter 11 of the piston rod 12 cooperates with this.

The longitudinal displacement of this piston rod is done by that the threaded rod 14 engages in its internal thread 13, which can be rotated with the aid of a rear rotary knob 15 is. When the threaded rod 14 is rotated, the piston rod 12 therefore becomes the push piston forwards, depending on the direction of rotation or moved backwards.

The rotary knob 15 has a radial annular bead 17, which engages in a corresponding annular groove 18 on the inside of the device casing 1. In this way the one hand is the Rotary knob on the threaded rod fixed in the position of use, on the other hand, it is secured against longitudinal displacement.

A rotary cap 19 that can be applied can be assigned to the rotary knob which must be removed before the rotary knob can be operated. On the front side can that Device casing to be assigned a deodorant sleeve 20. / "

It is recommended that you proceed in this way when handling the cosmetic agent or the like. Supplied to the application member and distributed by this on the surface to be treated

that
• has been, / at the end of this activity, the threatening button 15 is threatened backwards a little in order to suck the remainder of the application agent that is still in the application element backwards, from which it cannot drip.
