Application arrangement for liquid materials

An application arrangement for flowing cosmetic Material generally comprises an elongated container along with a itself Longitudinal brush with radial bristles for handling the cosmetic product. The brush normally extends longitudinally in the container with means which is integral with the brush to releasably close the container and also to a handle to serve for handling the brush.

The problem with which the invention is concerned is the amount of flieasenden

Measure material that is transferred to the brush, i.e. both the amount and monitor the distribution of flowing material that remains on the brush, when the latter is pulled out of your container. On one side the job is to ensure that the brush is adequately supplied with the flowing material and is on on the other hand, to avoid impregnating the brush to such an extent which the material to be handled by the brush turns into lumps.

An employed means of removing excess liquid material from such Brush, when pulled out of the container, is a ring or an annular flexible one Lip made of elastomeric material at the entrance of the container, which is dimensioned so that he narrows the brush and strips it off. A disadvantage of this narrowing lip is that that the stripping process is too drastic and too little material remains on the brush. Another disadvantage is that the Leaving the bent bristles free from the narrowing lip of the same outwardly into theirs swivel the normal position and throw the adhering material off the brush.

009852/0229

A suitable amount of the liquid material should also be used for the purpose of suitable application adhere to the outer ends of the bristles, but the pivoting action prevents this purpose. Additionally, the narrowing lip doesn't create one close monitoring because any part that is of resilient construction is necessarily in proportion to the amount of superfluous material yields, so that the function as Measuring device is not available. The problem an adequate supply of flowing material to the brush changes when the Feed body for the liquid material is reduced in size in the container. When the feed body is initially large and the predominant part of the brush length in the feed body is immersed, the flowing material saturates the full length of the brush, and it is necessary to drastically reduce the amount of adhering material.

However, since the supply amount in the container decreases with use, and a smaller part of the Length of the brush is immersed, a lesser amount must be taken from the brush that is pulled out removed. When the feed body is reduced, the usual handling closes of the container is the turning of the container into different positions with a consequent transition

of the material to sections of the brush length which are not immersed when the Container stands upright, but such accidental turning of the container cannot prevent it Filling up the desired section of the brush length may be dependent. Hence, if the supply body for the liquid cosmetic agent is reduced, only a smaller one End portion of the brush can be sufficiently supplied with the liquid material by immersion.

One problem is to make provision for stretching the flowing material along the length of the To create brush length if only one end portion of the brush in the reduced Feed body is immersed.

The present invention addresses the problem of the amount of adhering flowing Control materials to prevent high impregnation of the brush and deals furthermore with the problem of redistributing the flowing material along the length of the brush, if a reduced feed body in the container an immersion of more than just one small end section of the brush * prevents.

In the application arrangement in which an elongated brush with radial bristles in a container can be used to collect a quantity of flowing material from a feed body in the container to prepare the application of the flowing material to the Person receiving the user is the degree to which the brush is pulled out is impregnated with the flowing material, controlled in that the container with a Entrance passage of appropriate training and appropriate dimensions is provided .. The entrance The passage is dimensioned so that it narrows the brush radially when it is pulled out and preferably has a length which is several times greater than the cross section, to create a large surface for interaction with the brush.

The radial compression of the withdrawn brush from the entrance passage measures the Amount of flowing material that remains on the pulled out brush, and it it should be noted that the entrance passage is made of relatively rigid material in order to be accurate Measure to allow.

009852/0229 '

When the brush is pulled out of the entrance passage is, a residual amount of flowing material remains on the inner surfaces of the Through, and when the brush is then reinserted, the brush takes that previously uncovered residual material on, so that there is a redistribution of the material along the brush results, even if only a small end portion of the Brush is initially immersed in the feed body.

The inlet passage is preferably enlarged with respect to the cross-sectional area of its inner to the outer end, so that gives maximum radial compression of the brush through the inner end of the passage. As the brush is withdrawn through the passage, the radial compression is reduced the brush progressively through the passage, so that consequently the tendency of the brush is progressively reduced, the rest to sweep flowing material out of the passage.

009852/0229

On the other hand, when the brush is reinserted through the passageway, the progressive radial compression of the brush causes the brush to increasingly brush effectively. In this way, when the brush is reinserted, a substantial amount of the remaining material is transferred to the brush for the purpose of increasing distribution of the flowing material in the longitudinal direction of the brush; at the same time, any amount of the remaining material that has not been transferred directly to the brush is returned to the interior of the container. In this V / else the E ingangsdurchgang reduces the loss of flowing material and also serves as means for promoting the distribution of the flowing material along the brush 'when only one. smaller end portion of the brush is immersed in the feed body.

Preferably, the brush itself is tapered towards its outer end in order to be advantageous with to work together with the correspondingly conical entrance passage. Preferably has the entrance passage is in the. generally longitudinal inner ribs, which in the radial direction can be tapered towards the outer end of the passage in order to achieve the desired pro-

Pig.7 a partial section similar to Pig.4, whereby the brush is in the entrance passage, when pulled out of the container.

In Pig. 1 a container 10 is shown which is provided with a removable closure 12, which is in screw engagement with the container, as shown in Pig. 2. The closure serves as a handle for a brush, indicated generally at 14 isüJ. The brush is of known type and has an axial core 15, which by doubling a wire and made by winding the double wire around a helical series of radial To hold the bristles.

According to the invention, the container 10 is provided with a sleeve 16 which is fixedly arranged on the container and an axial input passage 18 forms. In the construction shown, the sleeve 16 has a radial flange 20, which bumps against the edge of the container. That . outer end of the sleeve is countersunk 21 provided, which at its inner end with a circumferentially extending recess on the inside 22 for receiving a sealing ring made of foamed plastic material when bumped

with a recess shoulder 25 at the inner end the sinking is provided.

In the construction shown, a handle or rod 26 for the brush 14 abuts against the inner end wall of the closure 12 and has an enlargement 28, which with the surrounding Closure is connected and abuts against the outer end of the sleeve 16 when the container is closed is. The handle 26 of the brush also has a smaller enlargement 30, which is inserted into the recess 21 and compresses the sealing ring 24 when the container is closed, as shown in Pig.2.

The bottom end of the core 15 of the brush 14 is firmly seated in an axial bore 32 on the outside End of the handle 26 and the brush 14 preferably, but not necessarily, have one conical design, as shown, with the larger diameter at the bottom end located.

The opening or entrance passage 18 has a length which is several times greater than the cross-section or diameter, by one axial containment of the surface for wiping between the brush 14 and the passage walls

to accomplish.

As can be seen from Pig. 2 and 4, enlarged the entrance passage 18 is preferably in its cross-section from a minimum to its inner end to a maximum at its outer end. In its cross-section, the entrance passage 18 Circumferentially spaced, multiply connected parts which, in the embodiment shown, are in the form of inner elongated ribs 34. The ribs run conically in the radial direction towards the outer end of the passage and thus contribute to the progressive increase in the cross-section of the passage. As mentioned, the inner end of the entrance passage is essential smaller in cross-sectional area than brush 14 and preferably as shown although the outer end of the passage is smaller in cross-section than the brush.

As shown in cross section in Fig. 3, the particular embodiment of the invention eight ribs 34 evenly distributed around the circumference, which have eight alternating radial divisions 35 form. In this way, the inner edges of the ribs 34 limit a so-called inner diameter or circumference, and limit the outer ends of the radial divisions

- 12 -

009852/0229

a so-called outer diameter or circumference is the inner diameter of the entrance passage for example, approximately $ 30 to $ 40 des Diameter of the inner end of the brush 14, and the outer diameter can be approximately 75 to 85 $ the diameter of the inner end of the brush. In the particular embodiment the diameter of the countersink 21 is shown so that it is approximately equal to the maximum diameter of the brush 14. The entry to the eight compartments 35 can be sized to be approximately $ 40 des Inside circumference, d Jl. that about $ 60 of the bristles of each helical row of the brush is shrunk by the ribs 34 or are compressed radially, with the remaining portion of approximately $ 60 of the bristles can expand within the radial divisions 35.

The manner in which the entrance passage 18 cooperates with the brush 14 can be with reference to Fig.4 to 7 can be understood. As the brush is withdrawn from the container the first helical row of the brush initially contacts the inner end of the entrance passage as shown in Fig. 4 and in Fig. 6 shows how the eight ribs 34 of the passage when the first screw

009852/0229

shaped row of the brush leads in the entrance passage, eight corresponding tufts 36 of the first helical row rose dramatically inwards, while the eight divisions 35 eight other tufts 38 bend inward less strongly. Hence the finite interior removes Diameter of the entrance diameter at its inner ends considerable amounts of adhering liquid material from eight evenly spaced sectors 36 of the brush, with considerably fewer amounts of the adhering liquid material from the alternative eight sectors 36 in the eight radial Departments 35 are removed.

As the brush 14 is advanced through the entrance passage as shown in Figure 7, the eight inner tufts 36 of each helical row of the brush can become the same Expand the diameter, like the eight outer BüBchel 38 with a subsequent option for the liquid material, to a considerable degree from the eight inner tufts, whichever less are supplied to migrate to the outer tufts, which are more supplied. A subsequent The helical row of the brush thus reaches the outer end of the entrance passage with a predetermined measured amount

-U-

009852/0229

of liquid material which is substantially uniform around the circumference of the helical Row is distributed.

It is important to note that when using the brush to apply the liquid material on the person of the user the application is initially carried out from the outer ends of the bristles, so the problem is not just the transition of the adhering material to the Brush sized, but also to ensure that the outer ends of the bristles are even are supplied with the measured material. The eight outer tufts 38 of each are helical Row of brushes are only bent slightly as they traverse the length of the entrance passage, and the remaining ones the more bent inner tufts 36 expand, and these facts favor retention of adhering material on the outer ends of the bristles. As every helical row is only slightly compressed when it leaves the outer end of the passage, occurs just a slight expansion by snapping the helical thread back into its original position Shape a. If the helical rows were drastically compressed at the far end of the entrance passage, the freed bristles would come out so violently that they would remove a lot of the liquid

Throw away any material which desirably adheres to the outer ends of the bristles.

As the brush passes through the entrance passage in the is returned in the manner shown in Pig.7 A layer of the flowing material is deposited on the inner surfaces of the inlet channel, and there is a tendency that this remaining flowing material expands towards the outer end of the passage. The inclination however, the flow of material to expand along the inner surfaces of the lips 34 increases progressively because of the progressive increase in the inside diameter of the passage so that when considering the passage as a whole, the expansion effect against the outer end of the Reduced passage downwards. If the brush 14 is then inserted in the container, the bristles of the brush pass through the entrance passage in contrast to the method according to Pig.7 bent, and now the incline of the helical row of the brush increases, the remaining one To convey flowing material into the container, progressively, because the cross-sectional area of the entrance passage is progressively against its inner end diminished. It is clear that when the feed body for the flowing Material in the container is drastically reduced,

009852/0229

only one end portion of the brush is immersed in the feed body when the container stands upright, but the expansion of the rest of the flowing material in front of and results in back along the length of the pass when repeated Inserting the brush distributing the flowing material from the oversaturated immersed end portion of the brush to the portions of the brush which are not immersed are. In this way, the entrance passage serves to keep the flowing material longitudinally the brush to distribute.

Several modifications can be made to the device described without affecting but to remove it from the core of the invention.
