Sealable valve bag and method for making a sealable valve bag

Abstract

The valve bag includes a bag body having a valve end portion, the valve end portion constructed to form a filling passage in which a valve sleeve is inserted. The valve sleeve has a first end extending into the interior of the valve bag and a second end secured to the bag body. A valve protection member is secured to the second end.

What is claimed is:  
     
         1 . A valve bag apparatus for the containment of material, comprising: 
 a bag body portion having a valve end portion;    a filling passage formed in the bag body at the valve end portion;    a sealable valve sleeve secured within the filling passage, the sealable valve sleeve having a first end extending into the interior of the bag body and a second end extending exteriorly from the bag body;    a protection member secured to the second end; and    an adhesive member securing the valve sleeve to the bag body.    
     
     
         2 . The valve bag of  claim 1 , wherein the adhesive member is secured to the valve sleeve.  
     
     
         3 . The valve bag of  claim 1 , wherein the adhesive member is secured to the protection member.  
     
     
         4 . The valve bag of  claim 1 , wherein the adhesive member is a starch based glue.  
     
     
         5 . The valve bag of  claim 1 , wherein the adhesive member is a resin based glue.  
     
     
         6 . A method of constructing a valve bag, the method comprising the steps of: 
 providing a bag body portion having a valve end portion;    constructing a filling passage in the bag body at the valve end portion;    securing a valve sleeve within the filling passage, the valve sleeve having a first end extending into the bag body and a second end extending exteriorly from the bag body;    securing a protective member to the second end; and    affixing the protective member to a side wall.    
     
     
         7 . The method of  claim 6 , wherein the protective member is affixed to the side wall using an adhesive.  
     
     
         8 . The method of  claim 6 , wherein the protective member is affixed to the side wall using a starch based glue.  
     
     
         9 . The method of  claim 6 , wherein the protective member is affixed to the side wall using a resin based glue.  
     
     
         10 . A method of filling a valve bag, the method comprising the steps of: 
 providing an unerected valve bag having a valve end portion;    inserting a valve sleeve having a protective member into the valve end portion;    creating a valve sleeve passage in the valve end portion having a fixed lower surface and a moveable top surface;    inserting a filling member in valve sleeve passage;    discharging material through the filling member into the valve bag thereby reconfiguring the valve bag from the unerected position to an erect position.    
     
     
         11 . The method of  claim 10 , wherein the secured lower surface is secured to a side wall of the valve bag.  
     
     
         12 . The method of  claim 10 , wherein the secured lower surface is secured using an adhesive material.  
     
     
         13 . The method of  claim 12 , wherein the adhesive material is a starch based adhesive.  
     
     
         14 . The method of  claim 12 , wherein the adhesive material is a resin based adhesive.  
     
     
         15 . The method of  claim 10 , wherein the valve sleeve passage is created by moving the top surface using a suction device.  
     
     
         16 . The method of  claim 10 , wherein the valve sleeve passage is created by moving the top surface using a mechanical actuator.
