It consists of a stopper/extractor terminal assembly. The stopper has, in its lower and interior part, a cavity that allows the accommodation of organic and inorganic material that will be in contact with the liquid contained in the receptacle (bottle, can, bag, etc.), to which it will impart its characteristics (colour, flavour, bouquet, maturity, ageing, etc.), although a filter will be interposed in order to prevent contamination of the liquid with small particles (sediment). As this cavity prevents the use of conventional "corkscrews", on the outside it has a female-thread housing so that any current type of corkscrew replacing the conventional helical spike will be able to remove the stopper via the extractor end, which is a male thread, requiring less rotation than current corkscrews. According to the contents of the container and the pressure with which the stopper is fitted, it will have a number of hermetic sealing rings or O-rings.
