Prevention of biocontamination by mailing

Abstract

For a biological contamination by mail of a person to who it is addressed an envelope is used which has a material which forms an envelope with a closed inner space, and at least one throughgoing opening provided in the material so as to communicate an interior of the envelope with its exterior so that if a particulate material is introduced into the interior of the envelope it will discharge through the at least one through going opening outwardly and the particulate material will not stay in the interior of the envelope.

1 . An envelope preventing a biological contamination by mail of a person to who it is mailed, comprising a material which forms an envelope with a closed inner space; and at least one throughgoing opening provided in said material so as to communicate an interior of the envelope with its exterior so that if a particulate material is introduced into the interior of the envelope it will discharge through said at least one through going opening outwardly and the particulate material will not stay in the interior of the envelope.  
   
   
       2 . An envelope as defined in  claim 1;  and further comprising at least one another throughgoing opening which is spaced from said first mentioned throughgoing opening.  
   
   
       3 . An envelope as defined in  claim 1 , wherein said at least one throughgoing opening is located in one wall of the envelope.  
   
   
       4 . An envelope as defined in  claim 1 , wherein said at least one throughgoing opening extends through two opposite walls of the envelope.  
   
   
       5 . An envelope as defined in  claim 1 , wherein said at least one throughgoing opening is formed as a cutoff edge of the envelope.  
   
   
       6 . An envelope as defined in  claim 1 , wherein said at least one throughgoing opening is formed as a circular opening.  
   
   
       7 . An envelope as defined in  claim 1 , wherein said at least one throughgoing opening is formed as a semi-circular opening.  
   
   
       8 . An envelope as defined in  claim 1 , wherein said throughgoing opening is formed as an elongated slot.  
   
   
       9 . An envelope as defined in  claim 1 , wherein said at least one throughgoing opening is located near at least one edge of the envelope.  
   
   
       10 . A method of preventing biological contamination by mail of a person to who it is addressed, comprising the steps of providing an envelope which is formed of a material which forms the envelope with a closed inner space; and forming in the material at least one throughgoing opening which communicates an interior of the envelope with an exterior of the envelope, so that if a particulate material is introduced into the interior of the envelope it will discharge through the at least one throughgoing opening.  
   
   
       11 . A method as defined in  claim 10 , wherein said step of providing at least one throughgoing opening includes providing a plurality of throughgoing openings in the material.  
   
   
       12 . A method as defined in  claim 10 , wherein said step of providing at least one throughgoing opening includes providing the opening with a shape selected from the group consisting of a circular shape, a semi-circular shape, and a slot shape.  
   
   
       13 . A method as defined in  claim 10 , wherein said providing at least one throughgoing opening includes providing said throughgoing opening at an edge of said envelope.  
   
   
       14 . A method as defined in  claim 10 , wherein said step of providing at least one throughgoing opening includes providing said at least one throughgoing opening in at least one wall of the envelope.  
   
   
       15 . A method as defined in  claim 10 , wherein said step of providing at least one throughgoing opening includes providing said at least one throughgoing opening in two opposite walls of the envelope.  
   
   
       16 . A method as defined in  claim 10 , wherein said step of providing at least one throughgoing opening includes cutting off at least one corner of the envelope.  
   
   
       17 . A method as defined in  claim 10;  and further comprising shaking an envelope so as to enhance discharging of the particulate material from the interior of the analog to its exterior.  
   
   
       18 . A method as defined in  claim 10;  and further comprising testing a throughgoing nature of said throughgoing opening by introducing a tool through said throughgoing opening.  
   
   
       19 . A method as defined in  claim 10;  and further comprising the step of testing a throughgoing nature of said throughgoing opening by irradiating the envelope with a radiation showing whether the throughgoing opening is closed or open.
