Blister pack for a container

Abstract

The present invention relates to a blister pack sealed to the neck of a container and adapted to fit under the container lid forming a seal, said blister pack containing a liquid soluble material such as dissolvable aspirin. When force is applied to the blister pack, the base, which is comprised of a rupturable material, breaks and allows the liquid soluble material to be mixed with the liquid in the container. The blister pack remains as a seal for the container until it is desired that the user remove the blister pack for access to the container. The user can then re-seal the container using the container lid.

1 . A blister pack for use with a container having a body and an opening, said blister pack by including a rupturable base and a cover of formable material, said base and cover defining at least one pocket which accommodates an element to be added to existing contents of said container body, said blister pack being further adapted to seal said container opening. 
     
     
         2 . The blister pack as defined in  claim 1  wherein said opening is associated with a neck portion of said container, said base extending across the opening such that an outer perimeter thereof is fixed to the neck and acts as an anti-tamper seal. 
     
     
         3 . The blister pack as defined in  claim 2  wherein said base ruptures when a minimum amount of force is applied on said cover, causing said element to fall into the container body. 
     
     
         4 . The blister pack as defined in  claim 3  wherein the seal between the outer perimeter of the base and the container neck is such that rupture of said base to allow for said element to be added does not cause said seal to break. 
     
     
         5 . The blister pack as defined in  claim 2 , wherein said seal is such that the blister pack is manually detachable from the neck of the container. 
     
     
         6 . The blister pack as defined in  claim 2 , wherein said blister pack includes tabs which, when pulled, break said seal. 
     
     
         7 . The blister pack as defined in  claim 5  wherein said container further includes a lid that is removably attachable from said neck such that when the lid is attached it envelops said blister pack. 
     
     
         8 . The blister pack as defined in  claim 7  wherein said lid includes a means of sealing said opening when the blister pack has been removed. 
     
     
         9 . The blister pack as defined in  claim 1 , wherein said base is of a lower burst strength than said cover. 
     
     
         10 . The blister pack as defined in  claim 1 , wherein the cover is of thermoformable or coldformable plastic. 
     
     
         11 . The blister pack as defined in  claim 1 , wherein the base is of aluminum. 
     
     
         12 . The blister pack as defined in  claim 1 , wherein said existing content is a liquid and said element to be added is a liquid soluble material. 
     
     
         13 . The blister pack as defined in  claim 1 , wherein said existing content is a liquid and said element to be added is a liquid soluble powder. 
     
     
         14 . The blister pack as defined in  claim 1 , wherein said existing content is a liquid and said element to be added is a second liquid. 
     
     
         15 . The blister pack as defined in  claim 1 , wherein the rupturable base is porous and adapted to diffuse oxygen through said blister pack. 
     
     
         16 . A container including a blister pack as defined in  claim 1 . 
     
     
         17 . A container comprising:
 a body portion carrying a liquid, said body portion including a neck having associated therewith an opening;   at least one blister pack including a base and a formable cover defining a pocket therebetween, said pocket adapted to accommodate an element to be added to said liquid, said base extending across the opening and including an outer perimeter that forms a seal between the blister pack and the neck portion of the container, said base further being rupturable such that when sufficient force is applied to the formable cover and element in a direction against said base, the base ruptures and said element is added to the liquid, said seal being such that the container remains sealed after force has been applied and said base portion ruptured.   
     
     
         18 . The container as defined in  claim 17  wherein said seal is achieved using an adhesive between the neck of the container and the outer perimeter of the blister pack base. 
     
     
         19 . The container as defined in  claim 17  wherein said container further includes a removably attachable lid, said lid including a means of sealing said opening after the blister pack has been completely removed.
