Description

Device for applying hail varnish

The invention relates to a device for applying paint or comparable treatment agents of a liquid to pasty nature, in particular nail polish, together with a corresponding storage container, according to the preamble of claim 1.

Nail polish is usually found in small storage bottles. The brush intended for applying the nail polish is attached to the unscrewable part of the cap of the storage bottle in such a way that the unscrewable part of the cap also serves as the handle of the brush.

To prevent the brush hairs from bending when the bottle is screwed on, the tips of the brush hairs extend as far as the bottom of the container. Since nail polish bottles are designed as cheap disposable items and are therefore not precision instruments for cost reasons, the brush hairs normally end slightly above the bottom of the container for "safety reasons".

can be recorded.

According to the invention, the brush can be moved axially relative to the closure cap by means of a displacement mechanism. In this way, the user is able to push the brush a little towards the bottom of the container by pressing a button, so that the brush tip reaches the bottom without the closure cap having to be screwed on each time.

The sliding mechanism preferably has a limiter on both sides. This reliably prevents the brush from being pushed too far into the container.

On the other hand, the brush cannot be completely pulled out of the cap.

If the sliding mechanism also has a return spring, then you only need to press the mechanism down on one side, e.g. with your index finger. The return process is carried out by the return spring.

The sliding mechanism is preferably designed in such a way that the brush tip can just about reach the bottom of the bottle even when the cap is unscrewed.

In addition, the displacement mechanism, designed as a cylinder-piston arrangement, has reliable longitudinal guidance. If the displacement mechanism is also secured against rotation, the brush can be guided precisely.

If you do not want to use the stroke of the shifting mechanism to its full extent, e.g. to avoid the brush hairs being compressed too much when immersed deeper, or to avoid creating too much of a

absorbs the viscous residue of the paint, the sliding mechanism should be able to be locked at any point.

According to a further advantageous embodiment of the application device according to the invention, the displacement mechanism is constructed in the manner of a spindle consisting of a spindle nut and spindle rod, with the axial displacement in the longitudinal direction by finger pressure being superimposed on a rotary movement on the brush side. This results in a good stirring of the nail polish still in the bottle on the one hand, and an even wetting of the brush tip with polish on the other.

The nail polish bottle is perfectly sealed thanks to a precisely fitting cylinder and piston arrangement.

Such a seal can be further improved by adding an additional, flexible membrane.

The nail polish bottle according to the invention and its function are explained in more detail using the attached drawings.

Bs shows:

Fig. 1 shows a nail polish bottle according to the invention; Fig. 2 shows a similar bottle with the cap unscrewed.

The arrangement shown in Fig. 1 consists essentially of a nail polish bottle 2 serving as a storage container for nail polish 4. At its upper neck-shaped end 6, the nail polish bottle 2 has a conventional screw thread 8. The

a closure cap 12 provided with a complementary screw thread 10 is screwed on. A brush 14 serving as an application element is attached axially to the inside of the closure cap 12.

In contrast to conventional nail polish closure caps, the closure cap 12 according to the invention has a cylinder-piston arrangement that serves as a sliding mechanism.

The "cylinder", which in the present embodiment consists only of an upper 16 and a lower guide part 18, is fixedly connected to the closure cap 12. The brush 14, consisting of a brush handle 22 and bristles (hairs) 24, is also arranged axially on the piston 20, which is guided axially by the guide parts 16, 18. With the help of a ring 26 on the piston 20 and corresponding protruding edges 28, 30 on the closure cap 12, the stroke H of the piston 20 is limited in both directions, ie both upwards and downwards.

The starting position of the brush 14 and the stop position of the piston 20 are selected such that the brush 14 just reaches the bottom 32 of the nail polish bottle 2 both in the upper end position of the piston 20 with the screwed-on state of the closure cap 12, on the one hand, and in the lower end position of the piston 20 with the unscrewed state of the closure cap 12, on the other hand.

The upper end of the piston 20, which can be pressed in, protrudes from the closure cap 12. The piston 20, which can be pressed in with the index finger, is pushed back to its starting position and moved back with the help of a return spring.

As can be seen from Fig. 2, the tip of the brush hairs 24 is at a distance A from the bottle bottom 32 when the cap 12 is unscrewed. This distance A can be compensated by the piston stroke H.
