Abstract
Abstract The applicator has a reservoir (1) for nail polish, a brush (2), a chamber (3) formed inside a cap (27), with a liquid absorbing element (4) for cleaning the brush and ensuring that it is ready for use at all times, and a dosing device (5, 6, 7, 8) with a rotatable knob (5). A rotary movement of the knob (5) is translated into an axial movement of the piston (10) via a carrier rod (6) and a threaded hollow rod (7), whose outer thread (18) engages with an inner thread (19) of a fixed ring (8). Halting means (9) disposed in the rotatable knob allow a stepwise forwards movement of the piston (10), thus achieving a dosed delivery of nail polish to the brush (2). Another embodiment intends the reservoir with the brush and the cap which surrounds the brush and forms the chamber to be designed as a replacement unit which can be inserted in a housing in which the dosing device is disposed.

Applicator for applyina resin~ and la~a~ers Technical Field This invention concerns an applicator for applying~
resins and lacquers, particularly nail polish, according to the preamble of claim 1.
State of the art An applicator of the above type is disclosed in the German published patent application DE-OS 35 20 523. The applicator has a tip to which liquid can be compulsorily supplied in a precise dose. For this purpose there is, in the liquid reservoir, a displaceable piston which is displaced by a certain amount towards and onto the applicator tip each time a knob disposed at the rear of the applicator is operated. The liquid reservoir has an outlet sealed by a check valve, said outlet being connected with the applicator tip. An activating rod operable from the outside by means of the press knob extends coaxially to and through the liquid reservoir, and is intended to open the check valve. The activating rod is passed through the piston and is connected with the latter via a sort of one-way coupling in such a manner that when the activating rod is displaced to open the check valve, the piston is also displaced, but remains in the liquid reservoir when the activating rod is retracted.
The disadvantage of this design is that the piston has to be doubly sealed against the wall of the liquid reservoir on the one hand, and against the activating rod on the other hand. Moreover, it is scarcely possible to dose the liquid delivered to the applicator tip in as small a quantity as required since in any case, a minimum path is required for the activating rod to open the check valve. Around this minimum path, the piston is displaced each time downwards.
A similar applicator is disclosed in the English patent application GB 21 50 424. The applicator has a reservoir which is sealed by a piston. Connected with the piston is an activating rod which extends away from the reservoir. Along the activating rod is disposed a delivery mechanism which rotates the activating rod, which has a screw, by a small amount when a knob at the end of the applicator is depressed. Although this applicator does allow finer dosing it evident that an improbable number of individual parts are required for its production.
Both of the above-mentioned applicators are not well suited to be carried in handbags because of the risk of unintentionally and repeatedly operating the button.
The German published patent application 22 07 288 discloses another applicator. In it, a liquid reservoir is also sealed with a longitudinally displaceable piston, on which a threaded rod extends away from the liquid reservoir. Disposed around the threaded rod is a jacket with an inner thread, which is formed as a rotary disk at the end of the applicator.
By rotating this disk, the piston is displaced along the liquid reservoir. It is scarcely possible to achieve accurate dosing with this embodiment, eg. by displacing the piston forwards in a stepwise manner.
Since the piston can be displaced both forwards and backwards with the rotary disk there is no guarantee that on each rotation for a forward movement liquid is actually delivered. This applicator is however of a simple construction. To longitudinally displace the piston, the latter must not turn around its axis.
However there is a certain unreliability in the functioning since such rotation is to be prevented merely by the friction of the piston on the wall of the liquid reservoir.
Disclosure of the invention lo It is the task of this invention to propose an applicator of the above-mentioned type with which it is possible to achieve an accurate dosing and with which no unintentional forward movements of the piston occur.
Moreover, the piston should be of a very simple construction.
This task is solved with an applicator which has the features listed in the characterizing part of claim 1.
Preferred embodiments of the applicator are characterized in the dependent claims.
The simple constructional features of the applicator, with a rotary knob which can be operated from the outside whose rotary movement is translated via a thread into an axial movement of the piston, whilst the halting means built into the rotary knob allow a stepwise forward movement of the piston thus achieving a defined, portion-wise delivery of nail polish, ensure simple and reliable operation and highly reliable ~unctioning.
A preferred embodiment intends the reservoir with the brush and the cap covering the brush to be designed as a replacement unit. The replacement unit takes environmental considerations into account since the applicator is not designed as a disposable article, and 4 2~56390 all the parts of the applicator not subject to wear due to use are simultaneously replaceable without any danger of pollution.
A further advantage of the applicator according to the invention is that different replacement units, containing different colours of nail polish for example, can be inserted into the applicator as required. A replacement unit can be changed at any time. The remaining content and colour may either be viewed directly on the transparent reservoir or, in the case of one replacement unit inserted, can be read in a display window.
In embodiments without a replacement unit, the level and, depending on the location of the opening, the colour of the content of the reservoir can be made visible by contriving a slit-shaped opening which extends along the housing.
These said displays are important since it may be assumed that a fully transparent applicator is not highly desirable in the cosmetics field.
Short description_of the drawinqs The applicator of the invention will be described in more detail, by way of example, with reference to the drawings, in which:
Fig. 1 is a longitudinal section through an applicator according to the invention, Fig. 2 is a partial cross-section of the applicator of Fig. 1, along the lines II-II, Fig. 3 is a cross-section through the rotatable knob of the applicator, along the lines III-III in Fig. 1, Fig. 4 is another embodiment of the rotary knob, with which it is possible to retract the dosing device, Fig. 5 is a partially cut view of an applicator with a reservoir associated with a replacement unit, Fig. 6 is a replacement unit, Fig. 7 is an applicator according to Fig. 5, without replacement unit, and Fig. 8 is a section through the housing of the applicator of Fig. 7, along the lines VIII-VIII.
The best way of implementing the invention The outer shape of the applicator shown in Fig. 1 is essentially cylindrical. At one end of the cylinder is a removable cap 27 with an inner chamber 3, which is formed between the outer wall of a cap insert 37 and the inner wall of the cap, and in which there is a liquid-absorbing element 4. In the liquid-absorbing element 4 there are means, for example alcohol, for ensuring that a brush 2 is ready to be used at all times. The cap insert 37 has at least one sealing ridge 39. The cap 27 is designed to be screwed closed via the said sealing ridge 39 and a groove running in a helical shape on a closing section 38 of the reservoir.
A ring seal 40 disposed on the closing section 38 prevents the means for keeping the unit operational from evaporating. The cap 27 is used to cover the brush 2, which is disposed around a thin nail polish delivery duct 25 in the closing section 38.
The cap insert 37 is of an essentially hollow cylindrical shape. It becomes wider towards the opening of the cap so that when the cap is put on, there is no problem in centering the brush 2. The inner surface of the cap insert 37 is substantially adapted to the outline of the brush 2 and the abutting closing section 38 of the reservoir. In order to ensure that when the cap is put on, an atmosphere saturated with the means for keeping the unit operational develops as fast as possible, there should be as little hollow space as possible between the brush 2, ie. the closing section 38, and the cap insert 37.
This contributes substantially to prolonging the life of the means for keeping the unit operational. The cap insert 37 also serves to mechanically shield the element 4.
The latter is therefore prevented from swelling up and reducing the size of the opening for the brush 2.
The said duct 25 ends in a reservoir 1. The latter is encased by a cylindrical housing 31 and is sealed on the side opposite the duct 25 by a piston 10 which can be displaced along the cylindrical housing.
On the side furthest from the brush 2, the housing 31 is extended beyond the reservoir 1. This prolongation will be referred to below as the end portion and is designated by reference numeral 11. At the end of the said end portion 11 furthest away from the reservoir 1 there is an activating element, which, in the embodiment illustrated, is a rotatable knob 5. The knob 5 is operationally connected with the piston 10 via coupling elements 6, 7. Via the coupling elements 6, 7, the dosing device designated by 5, 6, 7 and 8 tran~lates a rotary movement applied to the knob 5 into an axial movement of the piston 10. Inside the knob 5 there is a hollow area 12, in which there are disposed coaxially to the longitudinal axis a carrier element 15 with a hexagonal recess 20, and are connected with the jacket-shaped wall of the cap via crosspieces 30. A
carrier rod 6 which is mounted rotatably, but axially undisplaceably, at the end of the end portion 11 which is furthest away from the reservoir 1, has an end which passes through the said hexagonal recess 20 and which is formed as a flexible spreading device with two forks 21. There are hooks 22 on the forks 21 for holding the knob 5, which, when the latter has been slid apen, partially overlap the carrier element 15. The spreading device rests on two opposite sides of the hexagonal recess 20. By rotating the knob, the carrier rod 6 is also rotated. There is a cover 23 to cover an opening in the knob furthest away from the end portion 11. The carrier rod 6, which extends along approximately the entire length of the end portion 11, engages in the opening of a longitudinally displaceable threaded hollow rod 7. The latter has an outer thread 18 which engages with an inner thread contrived on a ring 8. The outer surface 29 of the ring 8 is connected with the inside wall of the casing at approximately the transition point of the reservoir 1 and the end portion 11. This connection may be made either by adhering or by welding, or, as is often the case in plastic injection technology, can be made with appropriately formed grooves and elevations which can be pressed or snapped in to engage with one another. A
slit-shaped opening 33 which runs in the longitudinal direction of the applicator and extends over the end portion 11, serves as a display means to render visible the threaded hollow rod 7 and therefore the level of the content of the reservoir.

These said displays are important since it may be assumed that a fully transparent applicator is not highly desirable in the cosmetics field.
Short description_of the drawinqs The applicator of the invention will be described in more detail, by way of example, with reference to the drawings, in which:
Fig. 1 is a longitudinal section through an applicator according to the invention, Fig. 2 is a partial cross-section of the applicator of Fig. 1, along the lines II-II, Fig. 3 is a cross-section through the rotatable knob of the applicator, along the lines III-III in Fig. 1, Fig. 4 is another embodiment of the rotary knob, with which it is possible to retract the dosing device, Fig. 5 is a partially cut view of an applicator with a reservoir associated with a replacement unit, Fig. 6 is a replacement unit, Fig. 7 is an applicator according to Fig. 5, without replacement unit, and Fig. 8 is a section through the housing of the applicator of Fig. 7, along the lines VIII-VIII.
The best way of implementing the invention The outer shape of the applicator shown in Fig. 1 is essentially cylindrical. At one end of the cylinder is a removable cap 27 with an inner chamber 3, which is formed between the outer wall of a cap insert 37 and the inner wall of the cap, and in which there is a liquid-absorbing element 4. In the liquid-absorbing element 4 there are means, for example alcohol, for ensuring that a brush 2 is ready to be used at all times. The cap insert 37 has at least one sealing ridge 39. The cap 27 is designed to be screwed closed via the said sealing ridge 39 and a groove running in a helical shape on a closing section 38 of the reservoir.
A ring seal 40 disposed on the closing section 38 prevents the means for keeping the unit operational from evaporating. The cap 27 is used to cover the brush 2, which is disposed around a thin nail polish delivery duct 25 in the closing section 38.
The cap insert 37 is of an essentially hollow cylindrical shape. It becomes wider towards the opening of the cap so that when the cap is put on, there is no problem in centering the brush 2. The inner surface of the cap insert 37 is substantially adapted to the outline of the brush 2 and the abutting closing section 38 of the reservoir. In order to ensure that when the cap is put on, an atmosphere saturated with the means for keeping the unit operational develops as fast as possible, there should be as little hollow space as possible between the brush 2, ie. the closing section 38, and the cap insert 37.
This contributes substantially to prolonging the life of the means for keeping the unit operational. The cap insert 37 also serves to mechanically shield the element 4.
The latter is therefore prevented from swelling up and reducing the size of the opening for the brush 2.
The said duct 25 ends in a reservoir 1. The latter is encased by a cylindrical housing 31 and is sealed on the side opposite the duct 25 by a piston 10 which can be displaced along the cylindrical housing.
On the side furthest from the brush 2, the housing 31 is extended beyond the reservoir 1. This prolongation will be referred to below as the end portion and is designated by reference numeral 11. At the end of the said end portion 11 furthest away from the reservoir 1 there is an activating element, which, in the embodiment illustrated, is a rotatable knob 5. The knob 5 is operationally connected with the piston 10 via coupling elements 6, 7. Via the coupling elements 6, 7, the dosing device designated by 5, 6, 7 and 8 tran~lates a rotary movement applied to the knob 5 into an axial movement of the piston 10. Inside the knob 5 there is a hollow area 12, in which there are disposed coaxially to the longitudinal axis a carrier element 15 with a hexagonal recess 20, and are connected with the jacket-shaped wall of the cap via crosspieces 30. A
carrier rod 6 which is mounted rotatably, but axially undisplaceably, at the end of the end portion 11 which is furthest away from the reservoir 1, has an end which passes through the said hexagonal recess 20 and which is formed as a flexible spreading device with two forks 21. There are hooks 22 on the forks 21 for holding the knob 5, which, when the latter has been slid apen, partially overlap the carrier element 15. The spreading device rests on two opposite sides of the hexagonal recess 20. By rotating the knob, the carrier rod 6 is also rotated. There is a cover 23 to cover an opening in the knob furthest away from the end portion 11. The carrier rod 6, which extends along approximately the entire length of the end portion 11, engages in the opening of a longitudinally displaceable threaded hollow rod 7. The latter has an outer thread 18 which engages with an inner thread contrived on a ring 8. The outer surface 29 of the ring 8 is connected with the inside wall of the casing at approximately the transition point of the reservoir 1 and the end portion 11. This connection may be made either by adhering or by welding, or, as is often the case in plastic injection technology, can be made with appropriately formed grooves and elevations which can be pressed or snapped in to engage with one another. A
slit-shaped opening 33 which runs in the longitudinal direction of the applicator and extends over the end portion 11, serves as a display means to render visible the threaded hollow rod 7 and therefore the level of the content of the reservoir.
8 2Cs6390 Fig. 2 shows a cross section through the carrier rod 6 and through the threaded hollow rod 7. In the embodiment example illustrated, the carrier rod has a cross-shaped section and comprises four first ribs 17.
The threaded hollow rod 7 has four second ribs 16 protruding into its hollow space and which extend over the entire length of the threaded hollow rod, and are evenly distributed over the circumference of the cross section. The carrier rod 6 can be inserted between the second ribs 16 in such a way that it is longitudinally displaceable relative to the~threaded hollow rod 7, but cannot be rotated. The rotary movement of the knob transferred to the carrier rod 6 is transferred to the threaded hollow rod 7. This latter is displaced as a consequence of the thread 18, 19 with which it is engaged, in the direction of the longitudinal axis of the applicator. The end of the threaded hollow rod 7 which abuts the piston 10 has an added part 26 which abuts the piston 10 in a funnel-shaped indentation 28.
The piston 10 is provided with an O-ring to seal the reservoir 1.
In order to regulate finely and exactly the amount of nail polish stored in the reservoir 1 which is delivered to the brush 2, halting means 9 are provided, with which the piston 10 can be moved forward in a substantially stepwise manner. In this embodiment example these halting means according to Fig. 3, are disposed in the form of vanes 9 in the knob 5.
Starting from the said carrier element 15 of the knob 5, the vanes 9 extend spirally in the direction of the wall 14 of the knob. At the end of the end portion 11 nearest the knob substantially saw-tooth-shaped notches 13 are disposed along the inner wall of the g ZC56390 circumference, into which snap the flexible vanes 9.
This engagement is possible because the said end of the end portion and the knob overlap over a short area.
The halting means 9 and the notches 13 can be designed for example, so that the knob 5 can only be rotated in one direction.
Fig. 4 shows another embodiment of a rotary knob.
The overlap region of the rotary knob 5 with the end of the end region 11 is enlarged with respect to the example previously illustrated. Between the front side of the carrier element 15 furthest from the reservoir and the forks of the spreading device 21, a pressure spring 43 is held between a support disk 41 and a sealing disk 42. The knob 5 can be lifted off the applicator by an amount determined by the distance of the two said disks. When this happens, the vanes 9 disengage from the notches 13 and the threaded hollow rod 7 can be rotated back into its starting position.
When the button 5 is released, engagement chamfers 44, which are disposed to the side of the notches 13, ensure that the vanes 9 engage again with the notches 13.
Figs. 5, 6 and 7 show an applicator of the type mentioned above, in which the reservoir 1 with the sealing piece 38 and the brush 2 attached thereto as well as the cap 27 which surrounds the chamber 3, are united as a replacement unit 32. The replacement unit can be inserted into the housing 31 of the applicator.
The latter comprises a hollow area for receiving the reservoir 1 and the adjoining end portion 11, in which are disposed the previously described coupling elements for moving the longitudinally displaceable piston 10 which seals the reservoir. The rotary knob 5, which is preferably the same as that previously described with respect to Fig. 4, is disposed at the end of the housing 31 lying opposite the replacement unit. It is intended that the replacement unit 32 may be at least partially inserted into the housing 31 and engaged with the latter. By means of a simple manipulation, the replacement unit 32 should also be able to be disengaged or released again at any time for removal from the housing part 31. The example illustrated assumes that an elongated ridge 36, protruding on the surface, is disposed on the reservoir. On the inside of housing part 31 there is a lead-in groove 45 which has a lead-in enlargement 34 towards the open end of the housing part 31 so that the ridge 36 can be easily attached when the replacement unit 32 is inserted.
When the ridge 36 is located towards the rear end of the groove 45, the replacement unit 32 can be rotated with respect to the housing part 31, causing the ridge to overcome an obstacle to engagement 46, and engage in a window 35. This is a slit-shaped opening disposed in housing part 31, whose outline corresponds essentially with the outline of the ridge 36. Since the reservoir 1 with the ridge 36 is made from a transparent thermoplastic, the level and colour of the lacquer in the reservoir can be seen in the window through the ridge. Said slit-shaped opening serves on the one hand to retain the replacement unit 32 in the housing part 31 and, on the other hand, as a window. The adjoining surfaces of the ridge 36 engaged in the window 35, and the engagement obstacle 46, are essentally radially directed so that disengagement is impossible. Lying opposite, disposed on the side of the window 35 furthest away from the lead-in groove 45, there is a disengagement groove 47. On the corresponding side of the window 35, abutting the ridge, there is a disengagement obstacle 48 which may be overcome by the ridge. In accordance with the example illustrated, the disengagement obstacle may consist of one side surface of the window which forms an inclined plane, said side surface abutting an appropriately inclined surface of the ridge. By continuing to rotate the replacement unit 32 the wall of the window is raised by the side surface of the ridge and the ridge enters the disengagement channel. The replacement unit 32 can be removed from the housing part. Fig. 8 is a partial section illustrating what has just been described. The way in which the ridge 36 engages and disengages is illustrated in self-explanatory manner.
As already mentioned, the replacement unit 32 comprises the reservoir 1 and the cap 27 with its inner chamber 3. The side of the reservoir 1 nearest the cap 27 is sealed with the sealing section 38, which has also already been mentioned, and to which the brush (not visible in Figs. 5 and 6) is attached. On the side furthest away from the cap 27, the reservoir is sealed with the piston 10. The cap 27 is preferably, as mentioned at the beginning, designed to be sealed by a rotary movement. Simple engagement and disengagement of the replacement unit is then guaranteed if the lead- -in groove 45 and the disengagement groove 47 are disposed on the inner circumference of the housing part 31 in the direction in which the cap 27 is turned for sealing.
Although only one ridge 36 and one window 35 are shown in the embodiment example illustrated, in a preferred embodiment they may be disposed twice, 12 2 ~5 63 90 staggered at 180. Each window 35 will have one lead-in groove and one disengagement groove.
In this embodiment example, the reservoir 1 can be filled in the same way as described above, namely by welding on the sealing element 38 after filling with the lacquer. It is however also possible to manufacture the saaling element as one piece together with the reservoir and to seal the latter by inserting the piston 10 after filling. In this way, the reservoir could be designed as a returnable, refillable part.
The individual parts of the applicator are preferably made from thermoplastic. All parts coming into contact with the lacquer substance which contains alcohol must be made from an alcohol-impermeable thermoplastic, or from another material. For luxury production, it is also conceivable to produce individual parts from metal or plastic with a metallized surface. In this respect, there are no limits to the design.
The threaded hollow rod 7 has four second ribs 16 protruding into its hollow space and which extend over the entire length of the threaded hollow rod, and are evenly distributed over the circumference of the cross section. The carrier rod 6 can be inserted between the second ribs 16 in such a way that it is longitudinally displaceable relative to the~threaded hollow rod 7, but cannot be rotated. The rotary movement of the knob transferred to the carrier rod 6 is transferred to the threaded hollow rod 7. This latter is displaced as a consequence of the thread 18, 19 with which it is engaged, in the direction of the longitudinal axis of the applicator. The end of the threaded hollow rod 7 which abuts the piston 10 has an added part 26 which abuts the piston 10 in a funnel-shaped indentation 28.
The piston 10 is provided with an O-ring to seal the reservoir 1.
In order to regulate finely and exactly the amount of nail polish stored in the reservoir 1 which is delivered to the brush 2, halting means 9 are provided, with which the piston 10 can be moved forward in a substantially stepwise manner. In this embodiment example these halting means according to Fig. 3, are disposed in the form of vanes 9 in the knob 5.
Starting from the said carrier element 15 of the knob 5, the vanes 9 extend spirally in the direction of the wall 14 of the knob. At the end of the end portion 11 nearest the knob substantially saw-tooth-shaped notches 13 are disposed along the inner wall of the g ZC56390 circumference, into which snap the flexible vanes 9.
This engagement is possible because the said end of the end portion and the knob overlap over a short area.
The halting means 9 and the notches 13 can be designed for example, so that the knob 5 can only be rotated in one direction.
Fig. 4 shows another embodiment of a rotary knob.
The overlap region of the rotary knob 5 with the end of the end region 11 is enlarged with respect to the example previously illustrated. Between the front side of the carrier element 15 furthest from the reservoir and the forks of the spreading device 21, a pressure spring 43 is held between a support disk 41 and a sealing disk 42. The knob 5 can be lifted off the applicator by an amount determined by the distance of the two said disks. When this happens, the vanes 9 disengage from the notches 13 and the threaded hollow rod 7 can be rotated back into its starting position.
When the button 5 is released, engagement chamfers 44, which are disposed to the side of the notches 13, ensure that the vanes 9 engage again with the notches 13.
Figs. 5, 6 and 7 show an applicator of the type mentioned above, in which the reservoir 1 with the sealing piece 38 and the brush 2 attached thereto as well as the cap 27 which surrounds the chamber 3, are united as a replacement unit 32. The replacement unit can be inserted into the housing 31 of the applicator.
The latter comprises a hollow area for receiving the reservoir 1 and the adjoining end portion 11, in which are disposed the previously described coupling elements for moving the longitudinally displaceable piston 10 which seals the reservoir. The rotary knob 5, which is preferably the same as that previously described with respect to Fig. 4, is disposed at the end of the housing 31 lying opposite the replacement unit. It is intended that the replacement unit 32 may be at least partially inserted into the housing 31 and engaged with the latter. By means of a simple manipulation, the replacement unit 32 should also be able to be disengaged or released again at any time for removal from the housing part 31. The example illustrated assumes that an elongated ridge 36, protruding on the surface, is disposed on the reservoir. On the inside of housing part 31 there is a lead-in groove 45 which has a lead-in enlargement 34 towards the open end of the housing part 31 so that the ridge 36 can be easily attached when the replacement unit 32 is inserted.
When the ridge 36 is located towards the rear end of the groove 45, the replacement unit 32 can be rotated with respect to the housing part 31, causing the ridge to overcome an obstacle to engagement 46, and engage in a window 35. This is a slit-shaped opening disposed in housing part 31, whose outline corresponds essentially with the outline of the ridge 36. Since the reservoir 1 with the ridge 36 is made from a transparent thermoplastic, the level and colour of the lacquer in the reservoir can be seen in the window through the ridge. Said slit-shaped opening serves on the one hand to retain the replacement unit 32 in the housing part 31 and, on the other hand, as a window. The adjoining surfaces of the ridge 36 engaged in the window 35, and the engagement obstacle 46, are essentally radially directed so that disengagement is impossible. Lying opposite, disposed on the side of the window 35 furthest away from the lead-in groove 45, there is a disengagement groove 47. On the corresponding side of the window 35, abutting the ridge, there is a disengagement obstacle 48 which may be overcome by the ridge. In accordance with the example illustrated, the disengagement obstacle may consist of one side surface of the window which forms an inclined plane, said side surface abutting an appropriately inclined surface of the ridge. By continuing to rotate the replacement unit 32 the wall of the window is raised by the side surface of the ridge and the ridge enters the disengagement channel. The replacement unit 32 can be removed from the housing part. Fig. 8 is a partial section illustrating what has just been described. The way in which the ridge 36 engages and disengages is illustrated in self-explanatory manner.
As already mentioned, the replacement unit 32 comprises the reservoir 1 and the cap 27 with its inner chamber 3. The side of the reservoir 1 nearest the cap 27 is sealed with the sealing section 38, which has also already been mentioned, and to which the brush (not visible in Figs. 5 and 6) is attached. On the side furthest away from the cap 27, the reservoir is sealed with the piston 10. The cap 27 is preferably, as mentioned at the beginning, designed to be sealed by a rotary movement. Simple engagement and disengagement of the replacement unit is then guaranteed if the lead- -in groove 45 and the disengagement groove 47 are disposed on the inner circumference of the housing part 31 in the direction in which the cap 27 is turned for sealing.
Although only one ridge 36 and one window 35 are shown in the embodiment example illustrated, in a preferred embodiment they may be disposed twice, 12 2 ~5 63 90 staggered at 180. Each window 35 will have one lead-in groove and one disengagement groove.
In this embodiment example, the reservoir 1 can be filled in the same way as described above, namely by welding on the sealing element 38 after filling with the lacquer. It is however also possible to manufacture the saaling element as one piece together with the reservoir and to seal the latter by inserting the piston 10 after filling. In this way, the reservoir could be designed as a returnable, refillable part.
The individual parts of the applicator are preferably made from thermoplastic. All parts coming into contact with the lacquer substance which contains alcohol must be made from an alcohol-impermeable thermoplastic, or from another material. For luxury production, it is also conceivable to produce individual parts from metal or plastic with a metallized surface. In this respect, there are no limits to the design.
