Paper Roll Holder

Abstract

The invention relates to a paper roll support for use as a room air freshener, in particular for toilet paper rolls, with an internal space and a longitudinal axis ( 14 ) extending horizontally in the operating state. It is proposed according to the invention that a movable membrane element ( 54 ) extending along the longitudinal axis of the paper roll support ( 10 ) be arranged in the internal space ( 50 ), said membrane element subdividing the internal space into two chambers ( 72, 74 ), wherein the membrane element ( 54 ) is arranged in such a way that it moves about the longitudinal axis of the paper roll support ( 10 ) in the operating state on rotation of the latter in such a way that the volumes of the chambers defined by the membrane element ( 54 ) vary inversely, and wherein the chambers ( 72, 74 ) optionally have closable connection openings ( 82 ) for air exchange with the surrounding environment. The invention additionally relates to a system consisting of a paper roll support and a paper roll mounted thereon, a paper roll holder and use of a paper roll support.

       6 . A paper roll support according to  claim 4  wherein said membrane element ( 54 ) is trapezoidal and the distance between the longitudinal sides ( 56   a ,  56   b ) of the trapezium is between 1.2 times and 1.5 times, the maximum inner width of the main body ( 10 ). 
   
   
       7 . A paper roll support according to  claim 4  wherein said membrane element ( 54 ) is rectangular and is of a length which corresponds to 0.8-1 times the clear length of the internal space ( 50 ). 
   
   
       8 . A paper roll support according to  claim 4  wherein said membrane element ( 54 ) comprises
 (a) a flexible plastics film and/or   (b) a flexible textile and/or   (c) paper and/or   (d) paperboard.   
   
   
       9 . A paper roll support according to  claim 4  wherein said membrane element ( 54 ) comprises from individual segments connected together in an articulated manner. 
   
   
       10 . A paper roll support according to  claim 4  wherein said membrane element is weighted that it sags downwards when said paper roll support ( 10 ) is in the operating state. 
   
   
       11 . A paper roll support according to  claim 10 , wherein membrane element ( 54 ) is weighted by a rod ( 68 ), which extends in the middle of the membrane element ( 54 ) parallel to the longitudinal axis ( 14 ). 
   
   
       12 . A paper roll support according to  claim 1  wherein connection openings ( 82 ) for air exchange are provided in end faces of said paper roll support ( 10 ), wherein each chamber ( 72 ,  74 ) has one connection opening ( 82 ) and the respective connection openings ( 82 ) of the two chambers ( 72 ,  74 ) are in opposing end faces of said paper roll support ( 10 ).
