in the following examples the hair treating device according to the invention is illustrated in different arrangement combined with media containers of different shape . the system according to the invention is however not limited to certain shapes of container or to certain relative angular settings . the hair treating device according to fig1 and 2 and globally designated by 1 comprises an oval cylindrical container 2 with base 3 and circularly shaped lid area 5 inclined through an angle ( a ) of 45 ° to the main vertical axis 4 of the container 2 . in the illustrated embodiment , the ratio of the larger elliptical semi - axis r to the smaller elliptical semi - axis r is 1 : sin 45 °. an exit hole 6 is disposed in the lid area 5 . this is surrounded by a nipple 7 on the outside of the lid area 5 . the longitudinal axis 8 of the nipple 7 is inclined through an angle ( a ) of 45 ° to the main axis 4 of the container body 2 . the applicator head which is globally designated by 11 , in the embodiment according to fig1 to 5 possesses substantially the shape of an inclined circular cone with a motional cone tip 14 lying perpendicularly above the circumferential line 12 of the cone base 13 and with cone height h being equal to the cone base diameter d ( see fig5 ). the center line passing through the center 9 of the circular lid area 5 of the container 2 coincides with the normal ( center line ) in the center 15 of the cone base 13 and thereby with the longitudinal axis 8 of the nipple 7 . given the above stated presumptions , the inclined circular cone , describing substantial parts of the surface of the applicator head , according to fig1 to 5 possesses a shortest generatrix 16 of the length of the height h and a longest generatrix 17 between the cone tip 14 and the cone base circumference 12 . for the stated angular and length relationships , the ratio of the length s of the longest generatrix 17 to the length h = d of the shortest generatrix 16 is 1 : sin 45 °. the applicator head 11 according to fig1 to 5 possesses a slot opening 18 , which extends parallel to the longest generatrix 17 and perpendicular to the area spanned by the cone base 15 and the longest cone generatrix 17 , at the exit opening 19 . communicating between this and the cone base surface 15 is a product channel 20 , which preferably has the shape of an inclined hollow cone . the product channel 20 narrows in the direction of a straight outlet channel 21 , which extends parallel to the longest cone generatrix 17 , up to the exit opening 19 . beyond that , a receiving nipple 22 for the force - locking ( click - fit ) coupling of the nipple 7 of the container 2 is provided in the interior of the applicator aid 11 , so that a locking rotation means is afforded . external views of a hair treating device 1 are illustrated in fig3 to 5 . in the view according to fig3 the lid area 5 , which is inclined through 45 ° to the vertical axis 4 of the container body 2 , yet circularly shaped when viewed perpendicularly , with nipple 7 is illustrated before the applicator head 11 has been placed on it . according to fig4 the applicator head 11 can be so rotated about its longitudinal axis 8 that the longest generatrix 17 forms a straight continuation of the adjoining generatrix of the container body 2 ( parallel to the main axis 4 of the container ). two slot surfaces 23 of the guide tines 24 and 25 bound the slot opening 18 and then extend likewise in a direction parallel to the vertical axis 4 of the container 2 . when the applicator head 11 is pivoted through 180 ° about the axis 8 according to fig5 the slot surfaces 23 , bounding the slot opening 18 , of the guide tines 24 and 25 are moved into a direction perpendicular to the main axis 4 of the container body 2 . in use , the applicator head 11 can through rotation by up to 180 ° about the axis 8 be pivoted out of the parallel into the perpendicular to the vertical axis 4 of the container 2 . since the container 2 itself forms the handle of the dyeing appliance 1 , a convenient manipulation at all places of the head is thus assured on use of the device according to the invention . a very significant feature of the invention is that the bristles 26 , end within the slot opening 18 , and thus are shorter than the guide tines 25 and 24 . the bristles 26 are arranged around the exit opening 9 in the slot opening 18 remaining between the guide tines 24 and 25 . the bristles 26 shall normally , i . e . without loading , stand about parallel to the slot surfaces 23 and to the longitudinal direction of the guide tines 24 and 25 . they serve to even out the dye or other media application and to improve the metering . in the drawing according to fig1 the notional part of the cone tip 14 of the applicator aid 11 is illustrated in dashed lines . as mentioned previously , for reasons of stability and safety , it is adviseable to shorten the cone in this region about transversely to the longest generatrix 17 so that the guide tines 24 and 25 are constructed as walls at both sides of the slot opening 18 affording them a stability adequate for the guidance of the hair to be dyed or otherwise treated . fig6 shows an example of an embodiment of an applicator head 11 with a body of about circular cone shape in the lower region and in a certain sense a distally projecting cone tip 14 &# 39 ; bent over about parallel to a generatrix . a product channel 20 , leading to the interior of the rotatably attached container 2 , with exit opening 19 again opens into this cone tip . the exit opening 19 is disposed between both of the guide tines 24 and 25 and is surrounded by bristles 26 . values of about 9 millimeters × 8 millimeters × 12 millimeters have proven useful for the respective length × width × height as dimensions of the guide tines 24 and 25 . the width preferably narrows to about 4 millimeters in the upper ( outer ) third . in the rotary setting of the applicator head 11 according to fig6 the guide tines 24 and 25 and the slot opening 18 disposed therebetween are evidently oriented about parallel to the main axis 4 of the container 2 and a generatrix , adjoining the applicator head 11 , of the container 2 . when the applicator head 11 is pivoted through 180 ° c . about its longitudinal axis 8 , the guide tines 24 and 25 are moved out of the parallel setting to the main axis 4 into a setting perpendicular to the main axis 4 . the manipulation and the details for the remainder agree substantially with the description of the hair treating device 1 according to fig1 to 5 . in the embodiment according to fig7 and 10 , an adapter 28 is placed between the applicator head 11 according to the invention and the container 2 . it is constructed on its side facing the applicator head substantially just as the container 2 according to fig1 and on its side facing the container 2 can possess a thread 29 for threading onto the mouth 30 of the container 2 . the connection between container 2 and adapter 28 can also be structured in different manner , such as a click - fit . it is significant that on the use of the adapter 20 , the requirement of elliptical container cross section in the rotational region of the applicator head 11 is removed . instead , a container 2 of any desired cross section can be used in the embodiment according to fig7 to 10 . the connection means between applicator head 11 and adapter 28 can , for example , be formed by the illustrated impact coupling 31 . the structure according to fig7 to 10 can , basically just as the hair treating devices according to fig1 to 6 , be equipped with a stopper 32 , which after the filling of the container 2 is placed as closure on the mouth 30 thereof . for completion , the adapter 28 with applicator head 11 fastened thereon can then be threaded onto the closed container 2 . on application , the consumer screws off the adapter 28 with applicator 11 , removes the stopper 32 and sets adapter and applicator head again onto the mouth 30 of the container 2 so that the hair treating device 1 according to the invention is ready for operation . after use of the device , the stopper 32 can again be set as closure onto the mouth 23 in reversed sequence of the manipulations . in still another embodiment ( not shown ) the invention device may have a non - rotatable ( i . e . fixed ) applicator head , which is integrally formed with the adapter 28 . in such instance , the bristles 26 and tines 24 , 25 may be permanently mounted parallel to the container vertical axis 4 and would have the same outward appearance as shown in fig8 as well as in the outline of fig7 . while the media flow channel of fig7 could still exist , there would be no need for either a rotation means or opposed faces of the adapter and applicator head , since they would be integrally formed . the internal structure of such a non - rotatable applicator head / adapter combination will be readily apparent to those skilled in the art . alternatively , the bristle 26 / tines 24 , 25 arrangement may be permanently perpendicular to the vertical axis 4 , in which instance the outward appearance would be the same as in fig1 , as well as in the outline of fig9 . the foregoing comments regarding the parallel aligned arrangement are otherwise applicable .
