Dispensing system with catching arm for sheet material rolls

Abstract

The invention relates to a roll of sheet material to be used in a dispenser having guides in opposing sides and at least one catching arm. The roll comprises a hollow core around which sheet material is wound, and a first and second end cap placed at each end of the core. The first end cap has a part of the end cap extending inside the core and a part that extends outwardly from an end surface. The outwardly extending part comprises a pin and at least a first annular part at least partly surrounding the pin. The invention further relates to a dispensing system for dispensing sheet material from a roll comprising an end cap at each end. The system comprises a dispenser and at least one roll of sheet material. The dispenser has opposing sides each having a guide that co-operate with the end caps.

       2 . A roll ( 2 ) according to  claim 1 , wherein the pin ( 11 ) extends further away from the end surface ( 10 ) of the first end cap ( 6 ) than the first annular part ( 12 ). 
   
   
       3 . A roll ( 2 ) according to  claim 1 , wherein the outwardly extending part of the first end cap ( 6 ) further comprises one or more additional annular part(s) ( 13 ), at least partly surrounding the first annular part ( 12 ). 
   
   
       4 . A roll ( 2 ) according to  claim 1 , wherein the second end cap ( 8 ) is of the same type as the first end cap ( 6 ). 
   
   
       5 . A dispensing system ( 1 ) for dispensing sheet material ( 20 ) from a roll ( 2 ), said system ( 1 ) comprising
 a dispenser ( 3 ) having
 a first and a second opposing sides ( 3   a ) each having a guide ( 4 ), and 
 at least one catching arm, 
   at least one roll of sheet material ( 2 ), said roll ( 2 ) comprising a hollow core ( 5 ) having a first and a second end ( 7 , 9 ), a first end cap ( 6 ) placed at the first end ( 7 ) and a second end cap ( 8 ) placed at the second end ( 9 ), the first end cap ( 6 ) having a part of the end cap ( 6 ) extending inside the core ( 5 ), said part having an end surface ( 10 ) at a distal end from the first end ( 7 ) of the core ( 5 ), and a part of the end cap ( 6 ) extending outwardly from the end surface ( 10 ), the outwardly extending part comprising a first annular part ( 12 ) having an inner and an outer diameter,   
     in which dispensing system ( 1 ) the guides ( 4 ) co-operate with the end caps ( 6 , 8 ), and the at least one catching arm ( 16 ) has a catching part ( 17 ) adapted to engage at least with the inner diameter of the first annular part ( 12 ) of the first end cap ( 6 ). 
   
   
       6 . A dispensing system ( 1 ) according to  claim 5 , wherein the dispenser ( 3 ) is adapted to receive one roll of sheet material ( 2 ), and wherein the at least one catching arm ( 16 ) comprises a guide ( 4 ) co-operating with the first end cap ( 6 ) and a catching part ( 17 ) adapted to engage at least with the inner diameter of the first annular part ( 12 ) of the first end cap ( 6 ). 
   
   
       7 . A dispensing system ( 1 ) according to  claim 5 , wherein the dispenser ( 3 ) is adapted to receive two or more rolls of sheet material ( 2 ), and wherein the catching arm ( 16 ) is moveable between a first position in which the first end cap ( 6 ) of an inserted roll ( 2 ) can pass the catching part ( 17 ) of the catching arm ( 16 ) and a second position in which the catching part ( 17 ) of the catching arm ( 16 ) engages with the first end cap ( 6 ) of an inserted roll ( 2 ). 
   
   
       8 . A dispensing system ( 1 ) according to  claim 7 , wherein the first end cap comprises a pin at least partly surrounded by the by the first annular part, and where in the pin ( 11 ) of a first inserted roll ( 2 ) moves the catching arm ( 16 ) from the first position to the second position. 
   
   
       9 . A dispensing system ( 1 ) according to  claim 7 , wherein the dispenser ( 3 ) further comprises a side track ( 18 ) placed in connection with and at an obtuse angle β to the guide ( 4 ). 
   
   
       10 . A dispensing system ( 1 ) according to  claim 9 , wherein the catching part ( 17 ) of the catching arm ( 16 ) is adapted to guide a roll ( 2 ) comprising a first end cap ( 6 ) having an outwardly extending part only comprising a pin ( 11 ) in such a way that the pin ( 11 ) is moved to the side track ( 18 ) when the catching arm ( 16 ) is in the second position.
