Injection-molded vacuum packaging machine

Abstract

A vacuum packaging machine having a chamber comprised of an injection-molded lid and an injection-molded basin.

We claim:  
     
         1 . A vacuum packaging machine having a vacuum pump and a vacuum chamber, wherein said chamber is comprised of a lid and a basin, said lid being injection-molded.  
     
     
         2 . The machine as recited in  claim 1  wherein said lid is comprised of a glass-filled resin.  
     
     
         3 . The machine as recited in  claim 1  wherein said lid is comprised of ISOPLAST 101 or Celstran TPU-GF30-01.  
     
     
         4 . The machine as recited in  claim 1  wherein said lid is concave.  
     
     
         5 . The machine as recited in  claim 1  wherein said lid contains a hole for viewing the contents of said machine during operation.  
     
     
         6 . The machine as recited in  claim 5  further comprising an L-shaped ledge that extends into said hole.  
     
     
         7 . The machine as recited in  claim 1  wherein said lid has four trapezoidal side pieces.  
     
     
         8 . The machine as recited in  claim 7  wherein said trapezoidal side pieces contain both an upper section and a lower section, said upper section being positioned more vertically than said lower section.  
     
     
         9 . The machine as recited in  claim 1  wherein said lid contains an edge having a groove.  
     
     
         10 . The machine as recited in  claim 1  wherein said lid contains at least one hinge extension.  
     
     
         11 . The machine as recited in  claim 1  wherein said lid contains at least one reinforcement bar.  
     
     
         12 . The machine as recited in  claim 11  where in said lid has two parallel and two perpendicular reinforcement bars.  
     
     
         13 . The machine as recited in  claim 1  wherein said lid contains at least one thickened corner having a reinforcement strip.  
     
     
         14 . A vacuum packaging machine having a vacuum pump and a vacuum chamber, wherein said chamber is comprised of a lid and a basin, said basin being injection-molded.  
     
     
         15 . The machine as recited in  claim 14  wherein said basin is comprised of a glass-filled resin.  
     
     
         16 . The machine as recited in  claim 14  wherein said basin is comprised of ISOPLAST 101 or Celstran TPU-GF30-01.  
     
     
         17 . The machine in  claim 14  wherein said basin has an L-shaped lip.  
     
     
         18 . The machine in  claim 17  wherein said L-shaped lip contains a strength strip in at least one corner of said L-shaped lip.  
     
     
         19 . The machine in  claim 14  wherein said basin has at least a flattened edge containing at least one hinge slot.  
     
     
         20 . The machine in  claim 14  wherein said basin contains at least one strength rib.  
     
     
         21 . The machine in  claim 20  wherein said at least one strength rib contains at least one pivot hole, said pivot hole used to mount a hinge block assembly to said lid.  
     
     
         22 . The machine in  claim 20  wherein said basin has a bottom wall having both an interior surface and an exterior surface and at least one strength rib contains at least one hole useful for permitting wires to cross the exterior and interior surface.  
     
     
         23 . The machine in  claim 16  wherein said basin contains two vertical pins, said pins useful for guiding a seal bar during operation.  
     
     
         24 . The machine in  claim 16  wherein said basin contains two vertical bars, said bars useful for guiding at least one filler plate during operation.  
     
     
         25 . A vacuum packaging machine having a vacuum chamber, wherein said chamber is comprised of an injection-molded lid and an injection-molded basin.  
     
     
         26 . The machine as recited in  claim 25  wherein said injection molding uses a glass-filled resin.  
     
     
         27 . The machine as recited in  claim 25  wherein said injection molding uses ISOPLAST 101 or Celstran TPU-GF30-01.
