Waste packing system with fusion seal apparatus

Abstract

The present invention is directed to a waste packaging device, a method of storing waste and to a film for use in this system and method. The device comprises a dispensing apparatus where a plastic film is stored, a bin where a fusion seal apparatus is located, and a fusion seal apparatus.

What is claimed is: 
     
         1 . A waste packaging device comprising
 a. a dispensing apparatus where a plastic film is stored   b. a bin where a fusion seal apparatus is located, and   c. a fusion seal apparatus containing sealing jaws and comprising a battery with a maximum voltage of equal or less than 20V,   
       characterized in that the movement of the sealing jaws is initiated by a rotation of an axis. 
     
     
         2 . The waste packaging device of  claim 1 , where the rotation of the axis is done with a help of a steering wheel. 
     
     
         3 . The waste packaging device of  claim 1  or  2 , where the dispensing apparatus has the form of a cassette. 
     
     
         4 . The waste packaging device of  claim 1 , wherein the voltage is less than 16 V. 
     
     
         5 . The waste packaging device of  claim 1 , wherein the voltage is less than 12V. 
     
     
         6 . The waste packaging device of  claim 1 , where the temperature for the heat seal is set to less than 100° C. 
     
     
         7 . The waste packaging device of  claim 1 , where the temperature for the heat seal is set to less than 90° C. 
     
     
         8 . The waste packaging device of  claim 1 , where the temperature for the heat seal is set to less than 80° C. 
     
     
         9 . The waste packaging device of  claim 1 , where the sealing time is set to less than 5 seconds. 
     
     
         10 . The waste packaging device of  claim 1 , where the sealing time is set to less than 3 seconds. 
     
     
         11 . The waste packaging device of  claim 1 , where the sealing time is set to less than 1 second. 
     
     
         12 . The waste packaging device of  claim 1 , where the plastic film is of a weight/surface ration less than 20 grams per square meter. 
     
     
         13 . A method for storing waste by using the device according to claim comprising
 a. pulling out plastic film from a dispensing apparatus   b. putting a waste item in a suitable length of the film   c. closing hermetically the plastic film with the use of a fusion seal apparatus where the seal is between a part of the film and another part of the same or other film, where the sealed parts are put sequentially in a bin,   
       characterized in that the movement of the sealing jaws is initiated by a rotation of an axis. 
     
     
         14 . The method of  claim 13 , where the rotation of the axis is done with a help of a steering wheel. 
     
     
         15 . The method according to  claim 13  or  14 , where the film comprises at least a layer of at least 50% per weight polyethylene homopolymer and/or copolymer,
 where the weight/surface ratio is less than 20 grams per square meter and the film can be heat sealed with the thermal energy transferred with a battery with a voltage of less than 20 V. 
 
     
     
         16 . The method of  claim 15 , where the film further comprises an internal layer comprising at least one oxygen barrier material, and/or an inner layer comprising at least 50% per weight polyethylene homopolymer and/or copolymer. 
     
     
         17 . The method of  claim 13 , where the film comprises at least
 an outer layer comprising polyethylene homopolymer and/or copolymer   an internal layer comprising at least one oxygen barrier material   an inner layer comprising polyethylene homopolymer and/or copolymer,   
       where the weight/surface ratio is less than 20 grams per square meter and the film can be heat sealed with the thermal energy transferred with a battery with a voltage of less than 20 V. 
     
     
         18 . The method of  claim 17 , wherein the outer and/or inner layer comprise at least 50% per weight polyethylene homopolymer and/or copolymer. 
     
     
         19 . The method of  claim 13 , where the weight/surface ratio of the film is less than 15 g/m 2 . 
     
     
         20 . The method of  claim 13 , where the weight/surface ratio of the film is less than 13 g/m 2 . 
     
     
         21 . The method of  claim 13 , where the film comprises an oxygen barrier material is EVOH, PVDC or polyamide, or where the polyethylene copolymer is a copolymer of ethylene and butene or a copolymer of ethylene and hexene or a copolymer of ethylene and octene.
