A mounting system to couple containers together includes a pair of container bodies coupled together, each container body having a bottom end connected to a top open end with a cap disposed thereon, a pair of recesses disposed in the bottom ends of the first and second container bodies, the recess of the first container body being sufficiently large to receive the cap of the second container body, the recess formed by an inner face coupled to a side wall, the side wall of the recess having a plurality of friction beam assemblies coupled thereto, each friction beam assembly in the plurality of friction beam assemblies separated from an adjacent friction beam assembly by space along the side wall of the recess. Insertion of the cap of the second container body into the recess of the first container body creates a frictional grip and a vacuum seal.
