Dispenser for rolled paper webs and a paper product for use in such a dispenser

Abstract

A centreflow web roll dispenser has a housing including a first section for attaching the dispenser to a support surface, a second section at least partially enclosing a radial circumference of a web roll, a third section enclosing a lower part of the web roll, a fourth section enclosing at least an upper part of the web roll, and an exit port in connection with the third section for dispensing a web from the web roll wherein a cross-section through the dispenser taken perpendicular to a central axis through a hole in the web roll has a major axis and a minor axis, the major axis being substantially parallel to the support surface for the dispenser. A web roll for use in such a dispenser and a method for compressing such a web roll are also disclosed.

1 . A centrefeed web roll, structured and arranged to be compressed into a non-cylindrical shape, wherein a cross-section taken perpendicular to a central axis through a centre hole in the web roll has a major axis and a minor axis; the cross-section of the web roll corresponding to a corresponding cross-section through a dispenser for which the web roll is intended; the major axis being substantially parallel to a support surface for the dispenser.  
     
     
         2 . The web roll according to  claim 1 , wherein the web roll has a roll density less than 0.2 g/cm 3 , but not less than 0.1 g/cm 3 , allowing manual compression of the roll before insertion into the dispenser.  
     
     
         3 . The web roll according to  claim 1 , wherein the web roll is permanently compressed.  
     
     
         4 . The web roll according to  claim 3 , wherein the web roll has a roll density in the range 0.2-0.3 g/cm 3 .  
     
     
         5 . The web roll according to  claim 1 , wherein the web roll is compressed into a substantially elliptical cross-section.  
     
     
         6 . The web roll according to  claim 1 , wherein the web roll is compressed into a substantially rectangular cross-section.  
     
     
         7 . The web roll according to  claim 4 , wherein the web roll is compressed so that its centre hole is at least partially collapsed.  
     
     
         8 . The web roll according to  claim 1 , wherein the ratio of the major axis over the minor axis is in the range 1.1:1 to 2:1.  
     
     
         9 . A web roll dispenser containing a centrefeed web roll according to  claim 1 , the dispenser having a housing comprising at least a first section for attaching the dispenser to a support surface and a second section at least partially enclosing a radial circumference of a web roll, whereby at least one end of the dispenser is provided with an opening for dispensing a web from said web roll, wherein a cross-section through the dispenser, taken perpendicular to a central axis through the web roll, has a major axis and a minor axis, the major axis being substantially parallel to the support surface for the dispenser.  
     
     
         10 . The dispenser according to  claim 9 , wherein the second section is connected to the first section by a resilient means.  
     
     
         11 . The dispenser according to  claim 9 , wherein the second section comprises a resilient sheet of material.  
     
     
         12 . The dispenser according to  claim 9 , wherein the dispenser further comprises a third section enclosing a lower part of the web roll, a fourth section enclosing at least an upper part of the web roll, and an exit port in connection with said third section for dispensing a web from said web roll.  
     
     
         13 . The dispenser according to  claim 12 , wherein at least the second section is removably attached to said first section to allow loading of the web roll.  
     
     
         14 . The dispenser according to  claim 12 , wherein a unit comprising the second and the fourth section is removably attached to at least said third section to allow loading of the web roll.  
     
     
         15 . The dispenser according to  claim 12 , wherein the third section, for enclosing a lower part of the web roll, is arranged to support the web roll.  
     
     
         16 . The dispenser according to  claim 9 , wherein the dispenser is configured for web rolls with an elliptical cross-section.  
     
     
         17 . The dispenser according to  claim 9 , wherein the dispenser is configured for web rolls with a substantially rectangular cross-section.  
     
     
         18 . The dispenser according to  claim 9 , wherein the ratio of the major axis over the minor axis is in the range 1.1:1 to 2:1.  
     
     
         19 . A method for producing deformed centrefeed web rolls according to  claim 1 , which method can be applied to single or multiple rolls, the method comprising steps of: 
 placing one or more rolls on a support surface, between opposing punching plates and an adjustable support plate;    applying a sufficient directional compressive loading on said one or more rolls by actuating said punching plates, to substantially deform said one or more rolls until said rolls contacts the support plate; whereby said one or more rolls are compressed into a non-cylindrical shape where a cross-section taken perpendicular to a central axis through a centre hole in the web roll has a major axis and a minor axis; and    relieving said compressive loading.    
     
     
         20 . The method according to  claim 19 , wherein the web roll is compressed into a substantially elliptical cross-section.  
     
     
         21 . The method according to  claim 19 , wherein the web roll is compressed into a substantially rectangular cross-section.
