Description

The The invention relates to a device for applying paint of a low viscosity viscous texture, in particular of nail varnish, with a supply bottle for the paint, with a cap for one Bottleneck of the storage bottle, with a centrally attached to the inside of the cap brush-shaped Application element and with a snap connection between the bottleneck and cap for a defined end position in the closed state.

Similarly designed Locking systems are known from WO 96/01 768 A1, with a Container, the with a bayonet connection with respect to the closing profiles and from the European draft standard (EN 14059). for oil lamps with safety lock, published in November 2000. Both documents contain the solution of a Security closure based on not on color bottles relates with an order element.

Known are, especially for Cosmetics, containers in the form of small storage bottles, in which the intended for applying the paint brush on unscrew Part of the closure of the Vorratsfläschchens is attached and the unscrewable part of the closure at the same time as a handle of the brush serves. As a locking system is the supply bottle to the bottleneck with an external thread and the cap of the storage bottle with provided a matching internal thread.

From the DE 195 08 836 A1 is a device for applying paint in particular for a cosmetics, known as nail polish, with a container in the form of a bottle with a screw cap, wherein a locking connection is provided, which holds the bottle neck and the cap in the closed state in a defined end position and the bottleneck for applying the cap on the bottleneck has a thread. In the DE 195 25 173 A1 Furthermore, a nail polish bottle is described, in which a bayonet closure is provided between the closure cap and the neck of the bottle and in the closed state, the brush tip just touches the bottom of the Vorratsfläschchens. Furthermore, the container bottom has a downwardly tapering reservoir-like depression.

Around a bending of the brush hair, the so-called broom effect, in the screwed To avoid the condition of the storage bottle, the tips of the brush hairs end in many nail polish bottles for safety reasons already slightly above the tank bottom. Because nail polish bottles as differently shaped disposable items are designed, resulting in practice different tolerances for the safety distance between brush end and container bottom.

Should Now the nail polish on fingernails and / or toenails are applied, so remove the cap with the attached brush from the storage bottle unscrewed, the excess color at the mouth stripped of the bottleneck and located on the brush hairs Paint in desired Way applied. To pick up another color of the brush is again in the storage bottle immersed.

One The problem is that it is due to the repeated Stripping the paint at the bottleneck mouth hardly makes it possible Paint over the edge of the bottle is running, wets the thread of the cap and thus the thread of the Bottle neck glued. Is the nail polish largely used up, so it is impossible at the bottom of the container of the storage bottle to get the rest of the nail polish on the brush. On the one hand ends for reasons the manufacturing tolerances always the brush tip in a certain Distance over the bottom of the storage bottle, on the other hand, you have to, with the brush tip at all near the bottom always re-tighten the cap or the vial tend so strong that the residual paint in it is the bottleneck runs around There to be picked up by the brush. That does not just happen An additional Operation, but it is also very arduous, the Vorratsfläschchen tighten again and tilt again as you can do both Hands needed. It already requires a great skill, if already some nails are painted, but the nail polish is not yet dry, the Vorratsfläschchen ambidextrous to open or to tilt to remove the nail polish residue with the brush too can, without the freshly painted nails to endanger.

The Invention has the object of these disadvantages to overcome, and to provide a device for applying paint, in which the brush also small paint residues from the Vorratsfläschchen without repeated screwing and unscrewing the cap or Tilting the storage bottle can record.

This object is achieved by the characterizing features of the single claim in that arranged outside the bottle neck closing profiles and the bottom of the inside of the closure cap lock pin and Forming a latching connection forming bayonet lock are engageable with each other, wherein each locking profile has a locking cam and a closing stop between which a latching groove for receiving the respective locking pin is formed, that in the closure cap, a seal is arranged, with one at the top The end of the bottleneck cooperates with an axial and a radial sealing surface such that the bayonet closure is closable against the pressure of the crimped seal, that each closing profile has a conical limit stop at the top, which corresponds to a delimiting cone on the inside of the closure cap, thereby the maximum possible applicator element immersion path is limited so far that a brush tip just touches a bottom of the Vorratsfläschchen that in the cap a guide cylinder is formed, in which the bottleneck during the closing process For better axial guidance dips, that at the lower end of the bottle neck firmly associated locking points are arranged, which support the lower inner edge of the cap during the closing process against tilting tendency, and that the container bottom around the central axis of the Vorratsfläschchens a Behälterbodeneinzug and a downwardly tapering reservoir-like depression having

Thereby, that are located on the cylindrical bottleneck and raised executed closing profiles only a partial area of the bottleneck circumference, those in the cap located, projecting to the center locking pin unhindered in the devoted spaces led down and the cap can be combined with brush in a single Use the maximum dive travel towards the bottom of the container. A user person is then able to brush until just before the bottom of the container to dive without for that purpose every time the cap must be screwed.

The with the cap firmly connected locking pin can be made by a small rotational movement the cap are placed in a position where they in the closing profile in a designated Engage groove. Through an audible and noticeable "click" when locking the locking pin the closed state of the storage bottle is clearly displayed.

The locking system has the advantage of a quick, comfortable and safe handling while closing and open of the storage bottle.

closure systems with the usual screw thread, by stronger or weaker Turn a variable closing pressure can generate not the tight condition of a container clearly indicate. In contrast, in the bayonet lock according to the invention achieved a defined in practice use not changeable closing pressure. The perfect tightness of the Vorratsfläschchens invention is made by a flexible, squeezable seal that is axial and radial acts, and achieved by a comparatively large sealing surface.

Furthermore the brush handle at the top of a shaft, which in the closed Condition in the opening of the bottleneck sticks out. In the lying state of the Vorratsfläschchens This prevents the color from escaping, ie a primary pre-seal causes. When closed, the shaft of the brush handle bears Furthermore to a tight fit in the upper part of the cap at.

One tight fit of the lower portion of the cap in the closed position Condition is opposed by two Locking points which are firmly connected to the container at the lower neck of the bottle, achieved. The locking points are dimensioned so that they support inner wall of the cap and thus a tendency to tilt prevent the cap.

The raised on the bottleneck positioned closing profile is from the top to the bottleneck obliquely upward sloping shaped. from that results in a limit stop against which the limiting cone optionally strikes in the cap and from which the advantage arises that when attaching the cap, the lower edge is not on the closing profile can sit up, but is derived.

The top of the neck is with a heel on the outer diameter provided, as a sealing surface acts. This results in an annular increase around the neck opening. This increase serves as Farbabstreifrand when removing the paint with the brush and stops the heel and the closure components are largely free of color, to gluing the locking mechanism to prevent.

The container bottom is further provided with a feeder, which extends depending on the outer contour of the container bottom annular, oval or angular around the central axis. The resulting wall on the outer container bottom circumference is used as a bottle base and ensures a stable state of Vorratsfläschchens. At the same time, the inner container bottom on the central axis on a pronounced depression, which expires towards the outer wall. This depression has the positive effect to As a result, the residual varnish in the storage bottle converges in the downwardly tapered recess like in a collection basin and can be completely absorbed with the brush. The problem of otherwise dried paint residues in nail lacquer bottles, caused by the unfavorable color bottle brush arrangement, is hereby solved.

The Combination of the closure system according to the invention with the in the container bottom of the stock vial trained collecting basin-like depression allows the complete removal in the storage bottle nail polish in a simple and comfortable way, without as usual Throw away dried paint residues, as conventional Color bottles with a brush assembly a complete color removal hardly possible in practice. Also from an ecological point of view is a big one Progress achieved by significantly less, by drying discarded nail polish residues pollute the environment.

in the Following, the invention will be explained in more detail with reference to an exemplary embodiments.

It demonstrate:

1 an inventive vials with dissolved cap;

2 the Vorratsfläschchen in the closed state;

3 the Vorratsfläschchen in plan view.

In the 1 illustrated device for applying paint of low viscosity to thick liquid composition consists essentially of a storage container for color, preferably nail polish serving vials 1 , In contrast to conventional nail polish bottles, the Vorratsfläschchen 1 in the middle on the outside of a bottleneck 23 two closing profiles 2 on. A cap 3 for the storage bottle 1 contains two latchable locking pins 4 , On the inside of the cap 3 is axially a brush-shaped applicator element 21 attached, a brush cone 7 and a shaft 8th includes.

To open the storage bottle 1 the back pressure of a squeezed seal must be 10 be overcome and the cap 3 Press down on the bottom of the inside of the cap 3 arranged locking pin 4 below locking cams 14 to be able to turn over in the direction of closing profile opening.

To remove the nail polish from the storage bottle 1 can be the order item 21 so far in the Vorratsfläschchen 1 be introduced until the seal 10 on an axial sealing surface 22 rests. The brush cone 7 of the brush-shaped applicator element 21 at the top of a brushstalk 6 causes a centering of the cap 3 when lowering the applicator element 21 and when closing the Vorratsfläschchens 1 , The locking pins 4 then be vertical to the closing profiles 2 passed by. To achieve an approximately unhindered immersion of the brush-shaped applicator element 21 , obstructed by the inwardly projecting locking pin 4 , assigns each closing profile 2 above a cone-shaped limit stop 11 with a trapezoidal outline. A usable immersion circle cutout α at the bottleneck circumference between the closing profiles 2 is thereby extended. The locking pins 4 are to over the trapezoid edges of the cone-shaped limit stop 11 derived downwards. Another favorable feature of this device are therefore on the inside of the cap 3 at the lower end V-shaped locking pin 4 , The withdrawal of the brush-shaped applicator element 21 nail polish on a brush handle 6 , is at an increased designed Farbabstreifrand 25 stripped.

The small height difference H between the open Vorratsfläschchen 1 ( 1 ) and the closed Vorratsfläschchen 1 ( 2 ), if necessary by a finger pressure on the cap 3 compensated, even exceeded with increasing pressure. With increased axial pressure on the cap 3 sits a boundary cone 5 on the cone-shaped limit stop 11 reliably prevents too deep immersion of the brush-shaped applicator element 21 into the container of the storage bottle 1 , The flexible seal 10 Its degree of hardness is such that compression without much effort is possible. As the pressure decreases, the cap will become 3 independently in their starting position accordingly 1 moved back.

When closing the storage bottle 1 from the starting position as in 1 shown, the locking pins move 4 in the direction of rotation for opening the closing profile 2 on obliquely downward closing edges 13 , The case in a guide cylinder 24 in the cap 3 is formed, protruding bottleneck 23 stabilizes the axial position of the cap 3 during the closing process. The thus achieved longitudinal guidance of the cap 3 counteracts a tilting tendency and allows a precise closing process.

By increasing rotation, the Ver closure cap 3 Pulled down, while at the same time the seal 10 against the axial sealing surface 2 2 and a radial sealing surface 26 crushed. The resulting back pressure of the seal 10 pulls the locking pin 4 complete with cap 3 while underrunning a locking cam 14 in a snap-in groove 12 to the outside at the bottleneck 4 arranged closing profiles 2 and the bottom of the inside of the cap 3 arranged locking pin 4 to engage each other to form a latching bayonet fitting, each closing profile 2 a locking cam 14 and a closing stop 15 between which the latching groove 12 for receiving the respective locking pin 4 is formed. The closing stop 15 and the locking cam 14 prevent unintentional rotation and secure the cap 3 in her position.

At the bottom of a bottle neck 23 of the storage bottle 1 are firmly arranged locking points 16 arranged, which are roof-shaped upwards to support the closing operation against tilting tendency, ie a seating of the locking pin 4 to prevent them from sliding off the slope.

A floor 20 of the storage bottle 1 with a container bottom feeder 17 and its resulting bottle base 18 is sized to the brush tip 9 the brush-shaped applicator element 21 in the lowered state of the applicator element 21 in one on the bottle central axis of the Vorratsfläschchens 1 lying and in the container bottom 20 Trained downwardly tapering reservoir-like depression 19 protrudes.
