Container attachable to another container for mixing ingredients

Abstract

A chamber member for containing a flavored powder or cereal for attaching to a container containing spring water or milk respectively in a manner for mixing the ingredients. The chamber member is molded to define a port extending therein and having a threaded cylindrical wall for threadedly receiving a threaded neck of the container. The chamber member has a portion which is integral with the cylindrical wall and sealingly closes an inner end of the port. The chamber member has a score line formed into and extending partially around the portion thereby defining a breakaway disc having an unscored hinge portion. The breakaway disc is slanted relative to the port cylindrical wall to allow initial contact by the neck with the breakaway disc at a location opposite the unscored hinge portion as the neck is threadedly advanced in the port to allow mixing of the ingredients. Instructions are provided for mixing the ingredients, including instructions on how to locate a suitable container.

1 . A chamber member for containing a first ingredient for attaching to a container containing a second ingredient in a manner for mixing the first and second ingredients, the chamber member molded to define a port extending into the chamber member and having a threaded cylindrical wall for threadedly receiving a threaded neck of the container, the chamber member having a portion which is integral with said cylindrical wall and which sealingly closes an inner end of said port, and the chamber member further having a score line formed into and extending partially around said portion thereby defining a breakaway disc having an unscored hinge portion, said breakaway disc being slanted relative to said port cylindrical wall to allow initial contact by said neck with said breakaway disc at a location opposite said unscored hinge portion as said neck is threadedly advanced in said port. 
   
   
       2 . A chamber member according to  claim 1  further comprising in combination therewith means providing instructions for attaching the chamber member to a container for mixing the ingredients. 
   
   
       3 . A chamber member according to  claim 1  further having at least one threaded neck defining a dispensing opening, said at least one threaded neck having a size to threadedly fit said threaded cylindrical wall, whereby a threaded cap threadedly receivable on the container neck is also threadedly receivable on said at least one chamber member neck. 
   
   
       4 . A chamber member according to  claim 1  comprising a single piece of molded plastic. 
   
   
       5 . A chamber member containing a first ingredient for attaching to a container having a threaded neck which defines an opening and containing a second ingredient in a manner for mixing the first and second ingredients, the chamber member being molded to define a port extending into the chamber member and having a threaded cylindrical wall for threadedly receiving the threaded neck, the chamber member having a portion which is integral with said cylindrical wall and which sealingly closes an inner end of said port, said portion being formed to be frangible so as to break as the neck is threadedly advanced in said port to bear against said portion thereby to allow the first and second ingredients to pass between a container and the chamber member for mixing thereof, and means in combination with the chamber member providing instructions for attaching the chamber member to a container for mixing the ingredients. 
   
   
       6 . A chamber member according to  claim 5  wherein said instructions include instructions on how to locate a suitable container for use with the chamber member. 
   
   
       7 . A chamber member according to  claim 5  further having at least one threaded neck defining a dispensing opening, said at least one threaded neck having a size to threadedly fit said threaded cylindrical wall, whereby a threaded cap threadedly receivable on the container neck is also threadedly receivable on said at least one chamber member neck. 
   
   
       8 . A chamber member according to  claim 5  comprising molded plastic. 
   
   
       9 . A chamber member according to  claim 5  wherein the chamber member further has a score line formed into and extending partially around said portion thereby defining a breakaway disc having an unscored hinge portion, said breakaway disc being slanted relative to said port cylindrical wall to allow initial contact by said neck with said breakaway disc at a location opposite said unscored hinge portion as said neck is threadedly advanced in said port. 
   
   
       10 . A chamber member according to  claim 5  wherein the chamber member contains a powder for mixing with a liquid in the container for drinking the mixture thereof. 
   
   
       11 . A chamber member according to  claim 5  wherein the chamber member has at least one side wall, wherein the chamber member contains cereal for mixing with milk in the container for eating thereof, and wherein said port extends into said side wall, whereby to permit the container to serve as a handle. 
   
   
       12 . In combination with a container which has a threaded neck defining an opening and which is devoid of a threaded port extending into said container, a chamber member attachable to said container in a manner to allow mixing of first and second ingredients in said chamber member and said container respectively, said chamber member being molded to define a port extending into said chamber member and having a threaded cylindrical wall integral therewith for threadedly receiving said threaded neck, said chamber member having a portion which is integral with said cylindrical wall and which sealingly closes an inner end of said chamber member port, said portion being formed to be frangible so as to break as said neck is threadedly advanced in said port to bear against said portion thereby to allow the ingredients to pass between said container and said chamber member for mixing thereof. 
   
   
       13 . A chamber member according to  claim 12  further comprising in combination therewith means providing instructions for attaching the chamber member to the container for mixing the ingredients. 
   
   
       14 . A chamber member according to  claim 12  further having at least one threaded neck defining a dispensing opening, said threaded container neck and said threaded chamber member neck having the same size, and a threaded cap which is threadedly receivable on both said threaded container neck and said threaded chamber member neck. 
   
   
       15 . A chamber member according to  claim 12  comprising molded plastic. 
   
   
       16 . A chamber member according to  claim 12  wherein the chamber member further has a score line formed into and extending partially around said portion thereby defining a breakaway disc having an unscored hinge portion, said breakaway disc being slanted relative to said port cylindrical wall to allow initial contact by said neck with said breakaway disc at a location opposite said unscored hinge portion as said neck is threadedly advanced in said port. 
   
   
       17 . A chamber member according to  claim 12  wherein the chamber member and the container contain powder and a liquid respectively for mixing for drinking the mixture thereof.
