Dispenser

Abstract

A dispenser for a roll of film material, comprising a cutting arrangement for cutting polyethylene having an upper portion and a lower portion, the upper portion being configured to move in relation to the lower portion between an open position and a cutting position. One of the upper portion and the lower portion comprises a blade, and the other of the lower portion and the upper portion comprises a cutting channel defined by a first pair of legs. The legs include at least one surface configured to reduce slip of film material across that surface.

1 . A dispenser for a roll of film material, comprising a cutting arrangement for cutting polyethylene having an upper portion and a lower portion, the upper portion being configured to move in relation to the lower portion between an open position and a cutting position;
 wherein one of the upper portion and the lower portion comprises a blade, and   the other of the lower portion and the upper portion comprises a cutting channel defined by a first pair of legs; and   wherein the legs include at least one surface configured to reduce slip of film material across that surface.   
     
     
         2 . A dispenser according to  claim 1  wherein the upper portion comprises the blade and the lower portion comprises the cutting channel. 
     
     
         3 . A dispenser according to  claim 1  wherein the at least one surface comprises a thermoplastic elastomer (TPE) coating. 
     
     
         4 . A dispenser according to  claim 1  wherein each leg comprises a top, a front, outer side and a rear, inner side, and wherein the top and front side of each leg and the rear side of one of the legs is coated with a TPE coating. 
     
     
         5 . A dispenser according to  claim 3  wherein the coating extends down approximately 50% of the front, outer side of each leg and a portion of the rear, inner side of one of the legs. 
     
     
         6 . A dispenser according to  claim 1  wherein when the upper portion is in the cutting position, the blade will cut the portion of film material by the time it has been stretched by a ratio of 4:1 from its original length. 
     
     
         7 . A dispenser according to  claim 1  wherein when the upper portion is in the cutting position the blade extends into the cutting channel by a distance of at least twice the width of the cutting channel. 
     
     
         8 . A dispenser according to  claim 1  wherein the first pair of legs are parallel to one another. 
     
     
         9 . A dispenser according to  claim 1  wherein when the upper portion is in the closed cutting position the blade is centrally positioned within the cutting channel. 
     
     
         10 . A dispenser according to  claim 1  wherein the blade is configured to meet the plane defined by tips of the legs perpendicular to that plane on movement of the upper portion from the open position to the closed cutting position. 
     
     
         11 . A dispenser according to  claim 1  wherein the first pair of legs are at least 1.5 mm thick. 
     
     
         12 . A dispenser according to  claim 1  wherein the upper portion further comprises a second pair of legs. 
     
     
         13 . A dispenser according to  claim 12  wherein when the upper portion is in the closed cutting position the second pair of legs is positioned outside of the first pair of legs. 
     
     
         14 . A dispenser according to  claim 1  wherein the upper portion and the lower portion are hinged together. 
     
     
         15 . A dispenser according to  claim 14  wherein the upper portion comprises a void configured to abut the lower portion so as to prevent horizontal movement of the upper portion during movement of the upper portion between the open position and the cutting position. 
     
     
         16 . A dispenser according to  claim 15  wherein the lower portion comprises a void configured to abut the upper portion.
