Flexible pouch having dispensing nozzle and frangible seal

Abstract

A collapsible pouch for motor oil includes a bulb-shaped storage chamber and an elongated dispensing nozzle. The storage chamber and the dispensing nozzle include first and second panels of a flexible laminate material secured together along opposite sides. The pouch further includes a burstable closure seal located in the dispensing nozzle including strips of an adhesively bondable material. The strips are capable of forming a bond having sufficient strength to maintain closure of the dispensing nozzle in the absence of a predetermined pressure applied to the motor oil. The pouch may include a bottom panel secured to the first and second panels to provide for self-support of the pouch when filled. The pouch may also include a removable end portion connected to the dispensing nozzle opposite the storage chamber.

What is claimed is:  
     
         1 . A collapsible pouch for engine lubricating oil comprising: 
 a storage chamber having a bulb shape when filled with an engine oil;    an elongated dispensing nozzle extending from the storage chamber, each of the storage chamber and the dispensing nozzle including first and second panels of a flexible laminate secured to each other along opposite sides; and    a burstable closure seal located in the dispensing nozzle, the closure seal including strips of an adhesively bondable material secured to confronting surfaces of the first and second panels, the strips capable of forming a bond having sufficient strength to maintain closure of the dispensing nozzle in the absence of a predetermined pressure applied to the engine lubricating oil.    
     
     
         2 . The pouch according to  claim 1  further comprising a removable portion connected to an end of the dispensing nozzle opposite the storage chamber, the removable portion including first and second panels of flexible laminate material secured to each other about a periphery of the removable portion such that the burstable closure seal is enclosed within the dispensing nozzle by the removable portion.  
     
     
         3 . The pouch according to  claim 2 , wherein a notch is formed in one of the opposite sides of the dispensing nozzle adjacent the removable portion to facilitate tearing of the pouch.  
     
     
         4 . The pouch according to  claim 1 , wherein the storage chamber further includes a bottom panel of a flexible laminate material secured to each of the first and second panels of the storage chamber, the bottom panel including opposite gusset folds to provide for self-support of the pouch when the pouch is filled with engine lubricating oil.  
     
     
         5 . The pouch according to  claim 1 , wherein the flexible laminate material of the storage chamber and the dispensing nozzle comprises at least one layer of polyethylene.  
     
     
         6 . The pouch according to  claim 1 , wherein the flexible laminate material of the storage chamber and the dispensing nozzle comprises at least one layer of nylon.  
     
     
         7 . The pouch according to  claim 1 , wherein the flexible laminate material of the storage chamber and the dispensing nozzle comprises at least one layer of polyethyleneterephthalate.  
     
     
         8 . The pouch according to  claim 1 , wherein the strips of the burstable closure include a cold seal adhesive material pattern applied to the respective first and second panels of the dispensing nozzle.  
     
     
         9 . The pouch according to  claim 1 , wherein the first and second strips of the burstable closure seal include a heat sealable material pattern applied to the respective first and second panels of the dispensing nozzle.  
     
     
         10 . A stand-up pouch for a liquid comprising: 
 first and second panels of a flexible laminate material each forming a portion of a storage chamber, the storage chamber having a generally rounded shape when filled with a liquid, the first and second panels further forming an elongated dispensing nozzle extending from the storage chamber, the first and second panels secured together along opposite sides of the panels;    a bottom panel of a flexible laminate material secured to each of the first and second panels to form a portion of the storage chamber, the storage chamber having a rounded shape when filled with a liquid, the bottom panel including gusset folds at opposite sides; and    a frangible seal located in the dispensing nozzle, the frangible seal including first and second strips of an adhesively bondable material respectively secured to the first and second panels, the strips positioned on confronting surfaces of the panels to provide for contact between the first and second strips and an adhesive bonding therebetween, the adhesive bond between the strips having a strength sufficient such that the contact between the strips will be maintained in the absence of a predetermined pressure applied to the pouch.    
     
     
         11 . The stand-up pouch according to  claim 10  wherein the first and second panels further form a removable portion of the pouch connected to an end of the dispensing nozzle opposite the storage chamber.  
     
     
         12 . The stand-up pouch according to  claim 11 , wherein the pouch includes a notch formed in one of opposite sides of the dispensing nozzle adjacent the removable portion to facilitate tearing of the pouch.  
     
     
         13 . The stand-up pouch according to  claim 10 , wherein the first and second strips of the frangible seal include a cold seal adhesive material pattern applied to the respective first and second panels.  
     
     
         14 . A container for a liquid comprising: 
 a storage chamber made from a flexible laminate material;    an elongated nozzle connected to the storage chamber, the elongated nozzle including an interior having opposing surfaces, the elongated nozzle made from a flexible laminate material such that the nozzle can be closed by bringing the opposing surfaces of the nozzle into contact with each other; and    a burstable seal located within the interior of the nozzle, the burstable seal including a layer of an adhesive material applied to at least one of the opposing surfaces, the adhesive capable of joining the opposing surfaces together with a sufficient bond such that the nozzle will remain closed in the absence of a predetermined pressure applied to the container.    
     
     
         15 . The container according to  claim 14 , wherein the nozzle includes first and second panels secured to each other along opposite sides of the panels and wherein the adhesive material is a cold seal adhesive pattern applied to the first and second panels.  
     
     
         16 . The container according to  claim 14  further comprising a removable portion connected to the nozzle opposite the storage chamber, the removable portion including first and second panels of a flexible laminate material.  
     
     
         17 . The container according to  claim 14  wherein the storage chamber includes first and second panels of a flexible laminate material secured to each other along opposite sides of the panels, the storage chamber further including a third panel secured to the first and second panels to form a bottom of a self-supporting container when the container is filled with a liquid.
