Container assembly having an overcap with a storage compartment

Abstract

There is provided an overcap that includes a storage compartment for receiving a product to be mixed with a hot liquid. The overcap includes a top wall defining the storage compartment in an underside of the top wall surrounded by an annular portion. The overcap includes an aperture in the annular portion. The overcap also includes a skirt extending downward from a rim surrounding the annular portion. The skirt extends below a lowermost surface of the top wall and can define a grip surface which a consumer may use to hold the container assembly, such that the grip surface insulates against heat if a hot liquid is held in the container. The storage compartment is sealed with a membrane that is relatively impermeable to moisture. In addition, the skirt includes a plurality of spacers on the inside surface of the skirt that are circumferentially spaced apart and that extend downwardly from the rim of the overcap.

       6 . An overcap of  claim 5 , wherein the plurality of spacers are circumferentially spaced apart from each other and extend downwardly from the rim of the overcap.  
   
   
       7 . An overcap of  claim 1 , wherein the storage compartment defines a domed portion.  
   
   
       8 . An overcap of  claim 7 , wherein the domed portion has incorporated therein a desiccant.  
   
   
       9 . An overcap of  claim 1 , wherein the membrane is relatively impermeable to moisture.  
   
   
       10 . An overcap for a container, wherein the overcap can store a product for mixing with a liquid held in the container, the overcap comprising: 
 a rim configured to engage the container;    a top wall defining a storage compartment in an underside of the top wall, the top wall having a substantially horizontal annular portion radially inward of the rim and surrounding the storage compartment;    a skirt extending downwardly from the rim, wherein the skirt defines a grip surface; and    a membrane removably attached to the underside of the top wall of the overcap covering the storage compartment for sealing a product contained in the storage compartment.    
   
   
       11 . An overcap of  claim 10 , wherein the skirt extends below a lowermost surface of the top wall of the overcap.  
   
   
       12 . An overcap of  claim 11 , wherein the skirt includes a plurality of spacers extending along an inner surface of the skirt.  
   
   
       13 . An overcap of  claim 12 , wherein the plurality of spacers are circumferentially spaced apart from each other and extend downwardly from the rim of the overcap.  
   
   
       14 . An overcap of  claim 13 , wherein the storage compartment defines a domed portion.  
   
   
       15 . An overcap of  claim 14 , wherein the domed portion has incorporated therein a desiccant.  
   
   
       16 . An overcap of  claim 10 , wherein the membrane is relatively impermeable to moisture.  
   
   
       17 . An overcap of  claim 10 , further comprising a drinking aperture defined in the annular portion.  
   
   
       18 . A container assembly comprising: 
 a container comprising a bottom wall and a tubular side wall upstanding from the bottom wall, the side wall having a top edge encircling a top opening of the container;    a cap having rim configured to engage the top edge of the container, the cap having a top wall defining a storage compartment in an underside of the top wall, the top wall having a substantially horizontal annular portion radially inward of the rim and surrounding the storage compartment, a drinking aperture being defined in the annular portion; and    a membrane removably attached to the underside of the top wall of the overcap covering the storage compartment for sealing a product contained in the storage compartment.    
   
   
       19 . A container assembly of  claim 18 , further comprising a skirt extending downwardly from the rim.  
   
   
       20 . A container assembly of  claim 19 , wherein the skirt extends below a lowermost surface of the top wall of the overcap and defines a grip surface.  
   
   
       21 . A container assembly of  claim 20 , wherein the skirt includes a plurality of spacers extending along an inner surface of the skirt, wherein the plurality of spacers are circumferentially spaced apart from each other and extend downwardly from the rim of the overcap.  
   
   
       22 . A container assembly of  claim 18 , wherein the membrane is relatively impermeable to moisture.
