Two bottles/containers in one

Abstract

Two bottles of any size, shape, color or texture one with a regular size spout, another with a much greater opening or any combination of the two. The concave bottom with a cap like grooved stopper within of the first bottle would allow the second bottles neck like structure to penetrate and twist itself tight into the first bottles bottom therefore creating only one bottle with two separate chambers. Allowing you to place any combination of liquid or solid matter like; soda, candy, soup and bread, detergent and fabric softener, oil and coolant, toys, t-shirts, trinkets etc.

1 . A drinking and/or dispensing device that allows another of the same nature to use its bottom as a cap in order for the bottle/container to twist itself into the cap like concave bottom to close shut thus; 
 a bottle with a concave, almost funnel like in shape bottom pointing upwards, within the bottle    a soda like cap found at the highest and thinnest top of the concave funnel to be noticed if looking inwards    looking inwards at the highest top of the concave cap of the first bottle grooves will be found    a second bottle without a cap    second bottle will penetrate the first bottles concave bottom    twisting the second bottle into the first to have one longer bottle with two separate chambers
