Device for applying cosmetic liquids

The invention relates to a device for applying cosmetic liquids, in particular perfume, with a housing for Receipt of a liquid supply and with a rotatably mounted in a bearing seat at the application end of the housing Sphere, part of which protrudes from the end of the application.

Devices with the structural features specified above are for applying, for example, deodorant liquids already known. The as an application surface the skin serving ball is in these known devices in a recess at the application end of the housing a certain preload held so that they are on the one hand on a part of the bearing seat forming lip rests sealingly at the end of the application and thus prevents the liquid from escaping when it is not in use, others on the other hand, however, is still rotatable due to the frictional contact with the skin. If the device is tilted, liquid will be spilled in the bearing seat of the ball so that it is wetted by it on its surface facing the interior of the housing and releases liquid onto the skin in the course of the rolling process.

The need to rotatably mount the ball in order to be able to effect the carrying process, allowed in the known Devices of this type only use relatively viscous liquids if a secure sealing

should be guaranteed when not in use. For thin liquids Cosmetic liquids, e.g. perfume, are the known devices are less suitable because the bearing seat of the ball is not sufficiently tight compared to this granted, so that leakage must be feared when lying down and unused.

There are also devices for applying cosmetic liquids that do not belong to the generic type dealt with above known, in which the application surface is characterized by a fixed membrane permeable to the liquid Fabric or foam is formed, under which a spring-loaded valve with a through the membrane actuatable valve body is arranged. By pressing the membrane against the skin, the valve is opened so that Fluid can leak, penetrate the membrane and be applied to the skin. The arrangement of the Valve, these devices are leak-proof, but the application takes place through rubbing contact with the skin, whereby Skin imperfections, fat and the like are deposited on the outer surface of the membrane over time. That will felt to be unsanitary. There is a common disadvantage of the two known devices discussed above in that the amount of liquid applied to the skin depends on the bearing seat of the ball or the back of the The amount of liquid supplied to the membrane depends, in turn, on the position of the device (more or less strong Tilting) fluctuates.

The invention is therefore based on the object of providing a leak-proof; To create device of the type mentioned, which is also for thin cosmetic liquids, in particular for perfume, and regardless of the position of the device, an even application of the liquid is useful allowed on the skin.

In accordance with the invention, this object is achieved in that the ball with at least part of its surface facing the interior of the housing with a body of capillary material connected to the liquid supply Contact is available.

In the device according to the invention, the cosmetic liquid to the spherical surface facing the interior of the housing not directly, but via the capillary Material of the body resting on the ball, i.e. controlled according to the conveying capacity of this body. Liquid is only sucked out of the body and again from the liquid reserve through its capillary action supplied as long as liquid is released by a rolling movement of the ball on the skin. If no liquid is dispensed, thus there is also essentially no fluid supply through the body of capillary material. Consequently the sealing ability of the ball in its bearing seat is sufficient even when using relatively thin cosmetic liquids the end.

Another important advantage is that the contact of the ball with the body made of capillary material possibly impurities absorbed by the skin continuously be stripped off the body and remain inside the device. The spherical surface itself always remains clean and hygienic.

According to a particularly advantageous development of the invention it is provided that the body of capillary material forms part of the bearing seat of the ball and expediently rests on the ball under elastic pretension. This plant can either be effected by it be that the body is slidably arranged and under

a spring load or the fact that the immovable The body held in the application end of the housing consists of an elastically deformable material and is subject to deformation is built in to the ball. In this embodiment, the body has either a dome-shaped one Bearing recess for the ball or forms it due to its elastic deformability, so that as a result, the ball is sufficiently wetted with liquid for a strong application. In addition, the elastic preload of the ball pressing it against the sealing lip of the bearing seat on the support side, whereby the Sealing when not in use is still improved.

An exemplary embodiment of the invention is explained in more detail below with reference to the accompanying drawing. The drawing shows, on a greatly enlarged scale, a longitudinal section through the order-side end of the (broken off) Housing of the device.

In the plastic or metal housing 1, which preferably has the dimensions of a conventional fountain pen or pen is used as a fluid reservoir a wick 2 made of capillary material emerged. The open end of the housing 1 is closed by a tightly fitted guide cap 3 which follows Tapered conically at the front and holds a socket 4 made of thin stainless steel sheet. The guide cap 3 has on its inside a number of radially inwardly projecting ribs 5, the rearward facing End faces serve as a stop for the wick 2 and their radially inwardly pointing longitudinal sides are a continuation of the Form the mounting hole 6 for the socket 4.

The socket 4 sits sealed with a neck-like part 7 in the receiving bore 6 and expands outside this

for receiving a preferably made of Teflon Ball 8. The ball 8 is held in a bearing seat, which is on the one hand by a curved circumferential sealing lip J-

9 of the mount 4 and, on the other hand, is formed by the front face ff of a body 10 made of capillary material. The body 10 is held in the neck part 7 of the holder 4 and protrudes with its rear end a piece immovable into the wick 2. It consists of an elastically deformable fiber material, such as synthetic fibers, which _means: are bonded to each other a resin and suppressed due to elastic deformation of the ball 8 against the sealing lip 9. This is the front end face of the body

10 dome-shaped on the back of the ball 8.

The guide cap 3 has a circumferential collar 11 with which it is supported on the end face of the housing 1 and which also serves to support a closure cap 12 of the device.

The outwardly widened part of the socket 4 allows the storage of a relative to the diameter of the housing large sized ball 8, the diameter of which is, for example, 1 cm. With a detachable attachment the socket 4 in the guide cap 3, after the amount of liquid contained in the wick 2 has been used up, it can be refilled and the device closed again use.

When using the device, the lip 9 protruding part of the ball 8 placed on the skin and the ball rotated by rubbing. Since the Ball 8 on the back through the body 10 of capillary material is supplied with liquid, it remains during the rolling process is constantly wetted, so that through the contact

fluid can be released onto the skin with the skin. When not in use, i.e. when no liquid is out the dome-shaped end face of the body 10 is removed, no liquid flows through this body either after. Possibly behind the bearing seat over time accumulating liquid is prevented from escaping by the pressure of the ball 8 on the sealing lip 9. Liquid on the surface of the sphere that for some reason has not been applied to the skin and is returned to the interior of the bearing seat, together with any impurities that may be present at the edge of the dome-shaped face of the body 10 stripped, so that only that amount of liquid is present on the ball that the supply through corresponds to the body 10.
