Packaging for freezer pops containing at least one active agent

Abstract

A packaging in the form of a freezer pop for storing a freezable liquid the packaging includes a sealed chamber for storing the freezable liquid formed from at least one inner layer having a sealable edge portion composed of a sealable material and sealed at the edge portion; at least one outer layer composed of a tear and puncture resistant material having an outside surface; at least one intermediate layer which is in sealable contact with both the at least one inner and outer layers, such that all layers are sealable together to form the sealed chamber; and at least one moisture barrier layer in proximity to the outer layer for at least substantially preventing moisture from escaping the sealed chamber for an extended period of time.

1 . A packaging in the form of a freezer pop for storing a freezable liquid, the packaging comprising: 
 a sealed chamber for storing the freezable liquid formed from at least one inner layer having a sealable edge portion comprised of a sealable material and sealed at the edge portion;    at least one outer layer comprised of a tear and puncture resistant material having an outside surface;    at least one intermediate layer which is in sealable contact with both the at least one inner and outer layers, such that all layers are sealable together to form the sealed chamber; and    at least one moisture barrier layer in proximity to the outer layer for at least substantially preventing moisture from escaping the sealed chamber for an extended period of time.    
     
     
         2 . The packaging of  claim 1  wherein the at least one moisture barrier layer is located between the intermediate and outer layers.  
     
     
         3 . The packaging of  claim 1  wherein one of the moisture barrier layers overlays the outside surface of one of the outer layers.  
     
     
         4 . The packaging of  claim 1  wherein the packaging has a water vapor transmission rate of less than 0.25 gms/100 inch 2 /24 hours at 100° F., 90% RH.  
     
     
         5 . The packaging of  claim 1  wherein the at least one moisture barrier layer is comprised of a low moisture transmission material selected from the group consisting of low moisture transmission polymer films and metal foils.  
     
     
         6 . The packaging of  claim 5  wherein the low moisture transmission polymer film is selected from the group consisting of polyvinylidene chloride and polychlorotrifluoroethylene.  
     
     
         7 . The packaging of  claim 5  wherein the metal foil is aluminum foil.  
     
     
         8 . The packaging of  claim 1  wherein the thickness of the at least one moisture barrier layer is up to 2 gauge.  
     
     
         9 . The packaging of  claim 1  wherein the sealable material is an adhesive material.  
     
     
         10 . The packaging of  claim 9  wherein the adhesive material is selected from the group consisting of pressure sealable adhesive materials, heat sealable adhesive materials, and combinations thereof.  
     
     
         11 . The packaging of  claim 10  wherein the sealable adhesive material is low-density polyethylene-linear low-density polyethylene.  
     
     
         12 . The packaging of  claim 1  wherein the sealable material is in the form of a sealable layer having a thickness of from 100 to 400 gauge.  
     
     
         13 . The packaging of  claim 1  wherein the tear and puncture resistant material is selected from the group consisting of polyethylene terephthalate, and oriented polypropylene, and biaxial nylon.
