Bulk bin and bag dispensing apparatus

Abstract

A bulk bin and bag dispensing apparatus comprises a bag fitment having an elongated buttress female thread and a nipple adapted to be joined to the bag fitment. The nipple comprises an elongated body portion having an axial flow passage therethrough and a projection portion extends radially therefrom. The body portion further includes a first end and a second end. The first end is defined by male buttress thread thereto and the second end is defined by NPT thread thereto. The first end includes a ring cutter and at least one sealing means attached thereto so that the nipple strokes threadedly within the elongated buttress female thread causing the ring cutter to puncture a bag membrane to thereby permit liquid to be dispensed through the flow passage.

What is claimed is: 
     
         1 . A bulk bin and bag dispensing apparatus comprising:
 a bag fitment having an elongated buttress female thread; and   a nipple adapted to be joined to the bag fitment, the nipple comprising an elongated body portion having an axial flow passage therethrough and a projection portion extends radially therefrom, the body portion further includes a first end and a second end wherein the first end defined by male buttress thread thereto and the second end defined by NPT thread thereto, the first end includes a ring cutter and at least one sealing means attached thereto so that the nipple strokes threadedly within the elongated buttress female thread causing the ring cutter to puncture a bag membrane to thereby permits liquid to be dispensed through the flow passage.   
     
     
         2 . The dispensing apparatus of  claim 1  wherein the at least one sealing means includes two O-ring seals that are disposed on the first end of the body portion. 
     
     
         3 . The dispensing apparatus of  claim 1  further comprising two O-ring gaskets each of which is respectively attached to corresponding opposed sides of the projection portion. 
     
     
         4 . The dispensing apparatus of  claim 1  wherein the second annular flange is a mounting flange that is attached to a plastic bag contained in a bulk bin. 
     
     
         5 . The dispensing apparatus of  claim 1  wherein the nipple forms a complete seal within the bag fitment prior to the ring cutter punctures the bag membrane. 
     
     
         6 . The dispensing apparatus of  claim 1  wherein the second end of the body portion is attached to a valve to discharge the liquid from the bag. 
     
     
         7 . A dispensing apparatus for use with intermediate bulk container defined by a bag and box combination wherein the bag and box combination is comprised of a collapsible bulk bin and a bag flexible material, the dispensing apparatus comprising:
 a bag fitment having an elongated buttress female thread, a first annular flange and a second annular flange spaced axially from one another and each of which extends radially from the buttress female thread;   a nipple adapted to be joined to the bag fitment, the nipple comprising
 an elongated body portion having an axial flow passage therethrough wherein the body portion further includes a first end and a second end defined by annular grooves, 
 a projection portion extends radially between the first end and the second end, 
 at least one O-ring seal being disposed onto the annular groove of the first end of the body portion, 
 a ring cutter being adapted to be joined to the first end of the body portion wherein the nipple drives through the elongated buttress female thread puncturing the bag membrane to thereby permits liquid to be dispensed through the flow passage while the nipple seats inside the buttress female thread and forms a complete seal within the bag fitment prior to the ring cutter punctures the bag membrane. 
   
     
     
         8 . The dispensing apparatus of  claim 7  wherein the at least O-ring seal includes two O-ring seals that are disposed on the first end of the body portion. 
     
     
         9 . The dispensing apparatus of  claim 7  dispensing fitment of  claim 1  further comprising two O-ring gaskets each of which is respectively attached to corresponding opposed sides of the projection portion. 
     
     
         10 . A dispensing apparatus for use with intermediate bulk container defined by a bag and box combination wherein the bag and box combination is comprised of a collapsible bulk bin and a bag flexible material, the dispensing apparatus comprising:
 a bag fitment having an elongated buttress female thread, a first annular flange and a second annular flange spaced axially from one another and each of which extends radially from the buttress female thread;   a nipple adapted to be joined to the bag fitment, the nipple comprising
 an elongated body portion having an axial flow passage therethrough wherein the body portion further includes a first end and a second end wherein the first end defined by male buttress thread thereto and the second end defined by NPT thread thereto, 
 a projection portion extends radially between the first end and the second end, 
 two O-ring gaskets each of which attached to respective opposed sides of the projection portion, 
 two O-ring seals being disposed onto the annular groove of the first end of the body portion so as to completely seals the first end of the body portion within the buttress female thread, 
 a ring cutter being adapted to be joined to the first end of the body portion and wherein the first end of the body portion strokes threadedly within the elongated buttress female thread causing the ring cutter to puncture a bag membrane to thereby permit liquid to be dispensed through the flow passage.
