Location arrangements

Abstract

A dispenser for dispensing sheet material from a roll. The roll has a location arrangement for releasably mounting the roll between a spigot and an oppositely facing support element for rotation about a longitudinal axis of the dispenser. The arrangement includes: a core around which the sheet material is wrapped, one end of the core being mounted or mountable relative to the support element, the other end having a wall region defining a generally hollow cylindrical portion projecting from the wrapped material, a generally axial slot being provided in the wall region extending to the free edge thereof; and a fixing provided on the cylindrical portion. The fixing has a bearing surface for rotatably engaging the spigot for rotational movement about the longitudinal axis, and a radial path to the bearing surface, the path being radially aligned with the slot in the core, whereby the end of the core may be laterally engaged with the spigot support element.

1 . A location arrangement for releasably mounting a roll of sheet material between a spigot and an oppositely facing support element for rotation about a longitudinal axis, the arrangement comprising: a core around which the sheet material is wrapped, one end of said core being mounted or mountable relative to said support element for rotation, the other end of the core having a wall region defining a generally hollow cylindrical portion projecting from the wrapped material, a generally axial slot being provided in the wall region extending to the free edge thereof; and a fixing provided on said cylindrical portion, the fixing having a bearing surface for rotatably engaging said spigot for rotational movement about said longitudinal axis, the fixing having a radial path to said bearing surface, the path being radially aligned with the slot in said core, whereby the end of the core may be laterally engaged with said spigot support element. 
     
     
         2 . A location arrangement as claimed in  claim 1 , wherein said fixing comprises a generally cylindrical inner portion for being push-fitted into the end of the cylindrical portion of said core. 
     
     
         3 . A location arrangement as claimed in  claim 1 , wherein the fixing includes one or more external constraining elements that fit around at least part of the outer surface of the cylindrical portion of the core. 
     
     
         4 . A location arrangement as claimed in  claim 2 , wherein the fixing includes one or more external constraining elements that fit around at least part of the outer surface of the cylindrical portion of the core. 
     
     
         5 . A location arrangement as claimed in  claim 3 , wherein the external constraining element comprises an external skirt extending around said fitting but interrupted adjacent the radial path. 
     
     
         6 . A location arrangement as claimed in  claim 1 , wherein the fixing includes at least one elements for resiliently and releasably trapping said spigot into engagement with an arcuate bearing surface of the fixing. 
     
     
         7 . A location arrangement as claimed in  claim 6 , wherein said at least one element for trapping comprises at least one flexible finger adapted to snap around said spigot in use. 
     
     
         8 . A dispenser for dispensing sheet material from a roll, comprising a spigot and an oppositely facing support element, and comprising a location arrangement for releasably mounting a roll of sheet material between the spigot and the oppositely facing support element for rotation about a longitudinal axis, the arrangement comprising: a core around which the sheet material is wrapped, one end of said core being mounted or mountable relative to said support element for rotation, the other end of the core having a wall region defining a generally hollow cylindrical portion projecting from the wrapped material, a generally axial slot being provided in the wall region extending to the free edge thereof; and a fixing provided on said cylindrical portion, the fixing having a bearing surface for rotatably engaging said spigot for rotational movement about said longitudinal axis, the fixing having a radial path to said bearing surface, the path being radially aligned with the slot in said core, whereby the end of the core may be laterally engaged with said spigot support element. 
     
     
         9 . A dispenser as claimed in  claim 8 , further including a guide surface provided adjacent said spigot onto which an external surface of the fixing and/or core may be pushed when the spigot is moved, relative to the fixing, along said radial path in use. 
     
     
         10 . A dispenser as claimed in  claim 9 , wherein the guide surface is curved to assist the user to manipulate the core of the roll clear of the spigot, at least when the roll is empty. 
     
     
         11 . A dispenser as claimed in  claim 8 , wherein the oppositely facing support element includes a U shaped formation having a edge facing the roll for abuting the material on the roll, and for allowing disengaging axial movement of the core away from the spigot when the core is spent. 
     
     
         12 . A dispenser as claimed in  claim 11 , wherein said support element further includes a restriction allowing forced removal of the core radially, when the roll is not spent. 
     
     
         13 . A roll of sheet material wrapped around a core, one end of said core having a wall region defining a generally hollow cylindrical portion projecting from the wrapped material, there being a generally axial slot provided in the wall region extending to the free edge thereof, and a fixing fitted into said cylindrical portion, the fixing having an arcuate bearing surface for rotatably engaging, in use, a spigot, the fixing having a radial path to said bearing surface, with the path being radially aligned with the slot in said core. 
     
     
         14 . A dispenser as claimed in  claim 9 , wherein the oppositely facing support element includes a U shaped formation having a edge facing the roll for abuting the material on the roll, and for allowing disengaging axial movement of the core away from the spigot when the core is spent. 
     
     
         15 . A dispenser as claimed in  claim 10 , wherein the oppositely facing support element includes a U shaped formation having a edge facing the roll for abuting the material on the roll, and for allowing disengaging axial movement of the core away from the spigot when the core is spent. 
     
     
         16 . A dispenser as claimed in  claim 14 , wherein said support element further includes a restriction allowing forced removal of the core radially, when the roll is not spent. 
     
     
         17 . A dispenser as claimed in  claim 15 , wherein said support element further includes a restriction allowing forced removal of the core radially, when the roll is not spent.
