Device for generating at least partial vacuum in bags for packaging clothes

Abstract

A device for generating at least partial vacuum in bags for packaging clothes comprising a box body that forms a suction chamber designed to accommodate at least one portion of a mouth of a bag for packaging clothes; elements for providing at least partial airtightness act between the bag and the box body; the suction chamber being provided with an air suction intake that can be connected to air suction elements; and heat-sealing elements that act on a region of the bag that is interposed between the mouth portion and the clothes contained within the bag.

1 . A device for generating at least partial vacuum in bags for packaging clothes, comprising a box body that forms a suction chamber designed to accommodate at least one portion of a mouth of a bag for packaging clothes, means for providing at least partial airtightness acting between said bag and said box-like body, said suction chamber having an air suction intake that can be connected to air suction means, said device comprising heat-sealing means that act on a region of said bag that is interposed between said at least one portion of said mouth and the clothes contained within said bag.  
   
   
       2 . The device according to  claim 1 , wherein said suction intake can be connected to a connector of a vacuum cleaner.  
   
   
       3 . The device according to  claim 1 , wherein said box body is formed in two parts that are associated to each other and can move with respect to each other in order to pass from an open condition, in which said at least one portion of said mouth can be arranged within said suction chamber, to a closed active condition, in which said sealing means form an at least partial seal between an outer surface of said bag and said two parts, in order to isolate said suction chamber from the outside.  
   
   
       4 . The device according to  claim 3 , wherein said heat-sealing means comprise heating means that are supported by at least one of said two parts.  
   
   
       5 . The device according to  claim 4 , wherein said heat-sealing means comprise said heating means on one of said two parts and an insulating element on the other one of said two parts, said insulating element facing said heating means when said two parts are in the active closed condition.  
   
   
       6 . The device according to  claim 5 , wherein said heating means comprise an electric resistor that is controlled by a control circuit and a protective element for said resistor that is designed to face said insulating element when said two parts are in the closed active condition.  
   
   
       7 . The device according to  claim 6 , wherein said protective element comprises a plate-like Teflon element.  
   
   
       8 . The device according to  claim 5 , wherein said insulating element comprises a plate element made of silicone material.  
   
   
       9 . The device according to  claim 3 , wherein at least one of said two parts comprises a recess that forms said suction chamber in cooperation with a portion of the other part that faces it in said closed active condition, said sealing means comprising at least one gasket that is designed to act between a perimetric region of said recess and the other part.  
   
   
       10 . The device according to  claim 3 , wherein said two parts are pivoted to each other about a rotation axis, in order to pass from said open condition to said closed active condition, and vice versa, means for retaining said two parts in said closed active condition being provided.  
   
   
       11 . The device according to  claim 3 , wherein said two parts comprise two elongated elements, which are pivoted to each other substantially at one of their longitudinal ends and form respective longitudinal recesses that are surrounded perimetrically by a sealing gasket, said elongated elements comprising, adjacent to said recesses, respectively said heating elements and said insulating elements, said elongated elements comprising said retention means at the other longitudinal end.  
   
   
       12 . The device according to  claim 1 , wherein said bag comprises, at least at a region that is proximate to said mouth, means for spacing internal surfaces thereof that form a plurality of air suction chambers.
