Benefits of technology

[0015] a metallic cap with internal plastic plastering (liner) in order to attain airtight closure and a “twist-off” threaded system or the like that allows for a quick opening;

[0017] an external aluminum cover, the internal diameter of which locks with the outside of the said plastic cube, in a cylinder-like and closed manner in one end on which are set the two parts referred to above. It may have different width and length, according to the purpose it is intended to serve, and it holds circular threads or frangible bridges in order to guarantee the safety of the content.

Problems solved by technology

For the sole purpose of mentioning just a few examples of the most widely known stoppers, we may begin by referring to the crown cap which, although it offers many functional advantages, such as prevention of leakage and safety, it is not an adequate stopper, from the aesthetical point of view, for the purpose of closing more expensive beverages, such as wine or champagne; additionally, it lacks certain relevant features for this kind of beverages, as is the case of safety mechanisms.

Another kind of stopper very commonly used in the market is the so-called “pilfer-proof”, which serves the purpose of prevention of leakage, safety and security, but presents the drawback of its high cost and, thus, it can only be used in those cases where so justified by the price of the beverage concerned.

As it is known, cork is a natural material obtained from the cork oak which, although offering the product an excellent aesthetical look, involves countless problems.

In fact, cork must be adequately shaped and placed; otherwise, it may affect the beverage.

Finally, cork is a high-price stopper; therefore, in the case of low-price beverages, second-class cork, called agglomerated cork, is used, which consists of small pieces of cork compacted and bound; this type of cork is not adequate for high-quality beverages.

However, they are not good for high-price beverages, since they pose countless inconveniences, especially due to inadequate adjustments between the stopper and the inner surface of the bottle neck, as well as the difficulty for their removal.
