Container Sealing Device

Abstract

The utility model can be used in food industry and it is designated for storage and/or transportation of containers filled with low-viscosity and normal-density fluids. The technical result of the present device is the improvement of the locking properties of the sealing ring of the stoppered container and the ability to use specific tamper-proof closures that need protection from overtwisting on the first unstopping and that contain both elements of fixation with the sealing ring collar of the stoppered container and a threaded joint. The above-mentioned technical result is achieved by introducing unidirectional hooks on the preform sealing ring or on the ready-made container sealing ring, namely the flanges must be placed on the side face of the sealing ring below the thread. Also, the technical result is partially achieved by the presence of the thread itself.

1 . A bottle sealing ring characterized by the presence of thread and an encircling projection, in addition to which on the lateral outer surface of the sealing ring there are added unidirectional hooks, located between the encircling projection and the thread of the sealing ring, that interact with the mating teeth of the closure or its elements as in a ratchet mechanism. 
     
     
         2 . The preform or bottle sealing ring abovementioned in the clause  1 , with the difference that the encircling projection is flattened and has holes.
