Mounting Assembly For a Paper Dispenser

Abstract

A mounting assembly for mounting a roll of sheet material having a central cylindrical opening in a dispenser for dispensing sections of the sheet material. The dispenser ( 10 ) is one of a type having a housing with a main plate ( 27 ) and a cover ( 14 ). The mounting assembly comprises a bung ( 30 ) having a tubular body ( 35 ) with a plurality of outwardly projecting ribs ( 34 ) operative to tightly engage an interior cylindrical surface of the roll of sheet material. A short cylindrical portion ( 32 ) of the bung is frangibly connected to the tubular body. A bung receptacle ( 16 ) is mounted on one of the main plate and the cover for receiving and retaining the short tubular portion in sliding engagement. A conical roll engagement element ( 20, 22 ) is mounted on another of the main plate and the cover operative to slidably engage an end of the central cylindrical opening of the roll of sheet material opposite to an end into which the bung is inserted.

       10 . A mounting assembly according to  claim 1 , wherein said roll engagement element is a conical element insertable into said central cylindrical opening. 
   
   
       11 . A dispenser of sections of a roll of sheet material having a housing with a main plate and a cover, comprising:
 (a) a bung having a tubular body with a plurality of outwardly projecting ribs operative to tightly engage an interior cylindrical surface of said roll of sheet material and a short cylindrical portion frangibly connected to said tubular body;   (b) a receptacle mounted on one of said main plate and said cover for receiving and retaining said short cylindrical portion in sliding engagement; and   (c) a roll engagement element mounted on another of said base plate and said cover operative to slidably engage an end of said central cylindrical opening opposite to an end into which said bung is inserted.   
   
   
       12 . A mounting assembly according to  claim 11 , wherein said bung further includes a flange extending outwardly at an intersection of said short cylindrical portion and said tubular body. 
   
   
       13 . A mounting assembly according to  claim 12 , wherein said plurality of outwardly projecting ribs each have a point directed towards said flange operative to resist withdrawal of said bung. 
   
   
       14 . A mounting assembly according to  claim 11 , wherein said plurality of outwardly projecting ribs have a sharp elongated edge extending parallel to said tubular body. 
   
   
       15 . A mounting assembly according to  claim 11 , wherein said tubular body has a round interior and a diameter larger than said short cylindrical portion. 
   
   
       16 . A mounting assembly according to  claim 11 , wherein said roll engagement element is a conical element insertable into said central cylindrical opening. 
   
   
       17 . A method of dispensing sections of a roll of sheet material having a housing with a main plate and a cover, comprising:
 (a) providing a bung having a tubular body for insertion into an end of said roll of sheet material and a short cylindrical portion frangibly connected to said tubular body;   (b) inserting said bung into an interior cylindrical surface of said roll of sheet material to tightly engage said tubular body with said interior cylindrical surface;   (c) placing said short cylindrical portion in rotational engagement with a receptacle mounted on one of said main plate and said cover for receiving and retaining said short cylindrical portion in rotational engagement; and   (d) placing an end of said central cylindrical opening opposite to an end into which said bung is inserted into rotational engagement with a roll engagement element mounted on another of said base plate and said cover.   
   
   
       18 . A mounting assembly according to  claim 17 , wherein said tubular body includes a plurality of outwardly directed projections.
