Cap for packing containers including an integral powder or liquid

Abstract

A cap for use with a container having a liquid food, the cap including a spout sealed at one end by a lid and at the other end by a foil and including a blister pack containing a component to be added to the liquid food at the time of consumption, the fully assembled cap adapted to be sealingly attached to the container having an opening sealed by a foil. Various mechanisms are proposed to break the foils of both the cap and the container to allow the component to be mixed with the liquid food. The cap may further include a seal to prevent ingress of particulates and/or water.

1 . A cap adapted to be sealingly attached to a container having a top wall and with an opening sealed by a first foil, the first foil extending under the top wall; the container holding a liquid food, the cap including a spout sealed at one end by a lid and at the other end by a second foil or rupturing material and including a component to be added to the liquid food at the time of consumption; whereby when the cap is attached to the container the first foil and the second foil are not in contact, there being a gap thereinbetween. 
     
     
         2 . The cap as in  claim 1  including a means to perforate both foils to allow the component to be mixed with the liquid food. 
     
     
         3 . The cap as in  claim 1  whereby the component is contained in a blister pack located in the cap. 
     
     
         4 . The cap as in  claim 3  whereby the bottom of the blister pack acts as the second foil. 
     
     
         5 . The cap as in  claim 1  whereby the cap includes a foot adapted to be sealingly attached to the top wall of the container.
