Tamper evident plastic bag incorporating a combination zipper and double resealable enclosure and method of manufacturing the same

Abstract

A tamper evident and resealable bag and associated method of producing having first and second sheets of a plasticized material and which are secured together along opposite extending side edges. A pair of reclosable portions extending in opposing and spaced apart fashion and proximate a top extending edge of the sheets of material. A looped header portion extends from the reclosable portions and along a selected distance corresponding to the top. A zipper is secured over the reclosable portions in proximity to the looped header portion. One or more items are pre-inserted into an open bottom established between the opposite extending sides of the first and second sheets and prior to sealingly engaging the bottom. The zipper is then traversed along the reclosable portions, in order to section the tamper-evident looped header portion in combination with opening an upper one of the pairs of reclosable portions, the lower pair of reclosable portions subsequently being manually disengaged to complete the opening process of the bag.

1 . A tamper evident and resealable bag, comprising: 
 a first sheet and a second sheet of a plasticized material, said sheets being secured together along opposite extending side edges;    at least one pair of reclosable portions extending in opposing fashion and proximate a top extending edge of said sheets of material;    a looped header portion extending from said reclosable portions along a selected distance corresponding to said top; and    a zipper secured over said reclosable portions in proximity to said looped header portion;    at least one item being pre-inserted into an open bottom established between said opposite extending sides of said first and second sheets and prior to sealingly engaging said bottom.    
   
   
       2 . The bag as described in  claim 1 , said zipper further comprising an axially extending slot through which said reclosable portions are seated, said zipper being traversable along said reclosable portions and in order to disengage said looped header portion.  
   
   
       3 . The bag as described in  claim 2 , further comprising first and second pairs of reclosable portions extending in spaced apart fashion along said top.  
   
   
       4 . The bag as described in  claim 3 , said zipper further comprising first and second extending slots for respectively seating said first and second pairs of reclosable portions.  
   
   
       5 . The bag as described in  claim 4 , further comprising said zipper traversing to reclosably open a selected one of said first and second pairs of reclosable portions.  
   
   
       6 . The bag as described in  claim 5 , further comprising said zipper traversing to reclosably open an upper selected one of said pairs of reclosable portions.  
   
   
       7 . The bag as described in  claim 1 , further comprising an end stop being formed at each of opposite ends of said reclosable portions subsequent to attaching said zipper.  
   
   
       8 . The bag as described in  claim 7 , said end stops each further comprising heat compressing said side edges of said bag and proximate said reclosable portions.  
   
   
       9 . The bag as described in  claim 1 , further comprising adhesively sealing said bottom following pre-insertion of said items.  
   
   
       10 . The bag as described in  claim 1 , further comprising heat sealing said bottom following pre-insertion of said items.  
   
   
       11 . A method of manufacturing a tamper evident and resealable bag, comprising the steps of: 
 securing together first and second sheets of a plasticized material along opposite extending side edges thereof;    forming at least one pair of extending and reclosable portions in inwardly opposing fashion and proximate top extending edges of said sheets of material;    forming a looped header portion in extending fashion from said reclosable portions and along a selected distance corresponding to said top;    attaching a zipper over said reclosable portions in proximity to said looped header portion; and    pre-inserting at least one item into an open bottom established between said opposite extending sides of said first and second sheets and prior to sealingly engaging said bottom.    
   
   
       12 . The method as described in  claim 11 , further comprising the step of traversing said zipper along said reclosable portions and in order to disengage said looped header portion.  
   
   
       13 . The method as described in  claim 11 , further comprising the step of forming first and second pairs of reclosable portions in spaced apart fashion.  
   
   
       14 . The method as described in  claim 13 , further comprising the step of attaching said zipper to said first and second pairs of reclosable portions.  
   
   
       15 . The method as described in  claim 14 , further comprising the step of traversing said zipper to reclosably open a selected one of said first and second pairs of reclosable portions.  
   
   
       16 . The method as described in  claim 15 , further comprising the step of reclosably opening an upper selected one of said pairs of reclosable portions.  
   
   
       17 . The method as described in  claim 11 , further comprising the step of forming end stops at opposite ends of said reclosable portions and subsequent to attaching said zipper.  
   
   
       18 . The method as described in  claim 17 , said step of forming end stops further comprising heat compressing said side edges of said bag and proximate said reclosable portions.  
   
   
       19 . The method as described in  claim 11 , further comprising the step of adhesively sealing said bottom following pre-insertion of said items.  
   
   
       20 . The method as described in  claim 11 , further comprising the step of heat sealing said bottom following pre-insertion of said items.
