Envelope

Abstract

An envelope is disclosed herein which comprises a perforated line 1 formed parallel in proximity to the edge of an envelope 10 preferably at the shorter edge 2 intersecting the closed flap 5 from one edge 3 to the opposite edge 4 . The sealed envelope can be opened by tearing along the perforated line 1 until the two parts 6 and 7 are completed separated.

1 . An envelope comprising 
 a flap attached to an edge of the envelope movable between an open position and    a sealed position in which in the sealed position the flap is folded on to the remainder of the envelope, and    a perforated line formed on the envelope whereby,    when the flap is in the sealed position, the perforated line runs through the flap and the remainder of the envelope.    
     
     
         2 . An envelope according to  claim 1 , wherein the perforated line is formed near to an edge of the envelope.  
     
     
         3 . An envelope according to  claim 2 , wherein the perforated line is substantially parallel to the edge of the envelope.  
     
     
         4 . An envelope according to any one of the preceding claims, wherein the perforated line extends from one edge to another edge of the envelope.  
     
     
         5 . An envelope according to any one of the preceding claims, wherein the flap is formed on a short side of the envelope.  
     
     
         6 . A method of producing a perforated line on an envelope having a flap movable between an open and a sealed position in which in the sealed position, the flap is folded on to the remainder of the envelope, the method comprising the steps of; 
 folding the flap to the sealed position, and    thereafter forming a perforated line through the flap and the remainder of the envelope.    
     
     
         7 . A method according to  claim 6 , wherein the perforated line is formed at a short side of the envelope.  
     
     
         8 . A method of producing a perforated line on an envelope having a flap movable between an open and a sealed position in which in the sealed position, the flap is folded on to the remainder of the envelope, the method comprising the step of; 
 forming a perforated line on the envelope, characterised in that when the flap is in the sealed position, the perforated line runs through the flap and the remainder of the envelope.    
     
     
         9 . An envelope comprising a perforated line formed on the surface parallel in proximity to the edge of the envelope preferably at the shorter edge characterized by said line formed over the closed flap of the envelope.  
     
     
         10 . An envelope according to  claim 9  in that perforated line can be applied to all sizes and types of envelope.  
     
     
         11 . An envelope according to  claim 9  in that perforations are dotted.  
     
     
         12 . An envelope according to  claim 9  in that perforations are short slit line.  
     
     
         13 . An envelope according to  claim 9  in that perforated line need not be straight.  
     
     
         14 . An envelope according to  claims 9  to  13  in that the method of opening is a perforated line.
