first , reference is made to fig1 through 3 . the brush according to the invention , shown as executed as a toilet brush , consists of a brush head 10 , as shown in fig1 and a brush head holder as indicated in fig2 in general by the number 20 and in fig3 in general by the number 30 . the brush head is executed as a one - way brush head and consists of a sleeve 2 that precisely fits the brush head holder 20 , 30 . if necessary , the sleeve 2 can be supplemented by an extension tube made of cellulose or the like in order to be able to effectively clean hard - to - reach places in toilet bowls , etc . connected to the sleeve 2 are several rolled - up paper strips or similar that serve as bristles and that are held together by a protective cover 3 . prior to using the one - way brush , the protective cover 3 must be removed , allowing the bristles 1 of the brush head 10 to unfold . after use , the brush head can be thrown off by means of a push button 4 on the brush head holder 20 , 30 and into the toilet bowl , and then disposed of . the brush heads of the invention consist of a well - degradable material , in particular a material that is easily soluble in water , e . g . one similar to toilet paper . preferably , the brush heads are made of cellulose or a water - soluble plastic that can be made from replenishable raw materials . such water - soluble plastic can be processed like normal plastic in jet moldings , but it has the advantage that the brush heads made of this material can also be disposed off via the toilet due to its water solubility . furthermore , the brush head can be impregnated with scent , cleaning and / or disinfection agents , with these agents preferably being used in gel form . the brush head holder 20 , 30 consists of a handle 5 made of metal , pvc or similar that the brush heads are stuck onto . the brush head holder is equipped with a mechanism 6 that makes it possible to slide off the brush heads by means of the push button 4 on the handle . the brush head holder 30 according to fig3 furthermore is equipped with a ball mechanism 7 that firmly locks the brush head in position after it has been stuck on . fig2 shows a simpler solution provided for manual use by hand [ sic ]. however , the model according to fig3 assures a better hold of the brush head on the brush holder and is intended for use with a one - way brush head dispenser . such a one - way brush head dispenser consists , e . g ., of a storage container with several brush heads that drops in front of a removal opening by force of gravity or a spring . several small knives may be arranged around the removal opening that tear open the protective cover of the brush head when it is pulled out of the removal opening . the brush head holder is stuck through the removal opening into the brush head and automatically locked in place by means of the ball mechanism . when the one - way brush is pulled out , the protective cover of the brush head is torn open and the one - way toilet brush is instantly ready to use . the process is shown in fig7 in the sequence a ) through d ). in step a ), a magazine for the storage container is first mounted on the wall with screws or , alternatively , with adhesive tape . the magazine has a front wall that can be folded out and whose lower end has an opening for the insertion of the brush head holder . in step b ), the storage container is placed into the magazine , and it can be seen that the brush sits in a holder on the right side of the magazine . in step c ), the brush head holder is stuck into a brush head , and the brush is thus ready to use . in step d ), the cleaning process can now be carried out . fig4 shows an additional model of a brush head holder 40 according to the invention in a side view . it differs from the models described above in that the handle 5 ′ is equipped with a bend α of approximately 155 °. this makes it possible to clean hard - to - reach places in toilet bowls as well . fig5 shows a longitudinal section through the brush head holder of fig4 that , for space reasons , was separated into two segments . from fig5 one can recognize additional differences of this model of the brush head holder vis - a - vis those of fig2 and 3 . the brush head holder 40 features a movable connection element 11 split lengthwise at the end of the brush head side in the interior of the handle 5 ′ that interlocks with a flexible ( necessary due to the bend ) extension 4 a of the push button 4 and which transfers translation motions of the push button 4 to the sleeve - shaped ejection mechanism 6 via a bolt 9 that can slide in oblong slots 5 a of the handle 5 ′. the ejection mechanism 6 features a flange 6 a that serves as a stopper for the protective cover of the brush head . the protective paper cover is pushed back to said stopper . the spring 12 resets the push button 4 to its starting position . in addition , a cap 8 that can be forced on by pressure closes the tube - shaped handle 5 ′ off . another model of a brush head holder 60 according to the invention is shown in fig6 . it differs from the design models of fig4 and 5 mainly in that the handle is composed of several parts , namely a grip part 5 b , a cone part 5 c , a connection tube 5 d , another connection part 5 e and a head part 5 f that features the oblong slots 5 a for the bolt 9 which traverses the connection part 11 ′. the ejection mechanism 6 is pushed over the head part 5 f . the parts of the handle can be formed of plastic , preferably however of stainless steel , and are cemented together . in contrast with the previous model , the push button 4 does not feature an extension , but is connected , by means of a stud screw 13 , to a relative stiff stainless - steel wire 14 whose other end locks into the connection part 11 ′. the wire 14 transmits the translation motions of the push button 4 to the connection part 11 ′. the spring 12 again serves to reset the push button 4 to its starting position . the connection tube 5 d of the handle is bent prior to the assembly in order to create the aforementioned bend .
