The present invention relates to a bottle stopper used as a closure which can be made of various silicones or polymers. The invention can be used in any circumstances in which a cork might be used. The present invention is a stopper for wine, soda and most other disposable bottles used by the home consumer.
The common material that has been used as a bottle closure is cork because of its' ability to generally remain intact. Cork can also remain in its' original form which has made it a reliable sealer. However, man-made materials have advantages over those that occur naturally. Substances that occur in nature can have many variances in consistency. A molding process guarantees uniformity. A natural cork can dry out and begin to break apart. These pieces can find their way into the liquid inside the bottle. With the pressure exerted to press and seal, corks can be difficult to remove and may break, leaving a portion of cork inside the bottle.
Synthetic wine stoppers are already available. The flexibility of silicone material used ensures ease of sealing and removal. The color and fleck added make the present invention's “glitz” a feature that makes this stopper even more desirable. The matching colors to seasons and wine varieties, in addition to low cost, make the stopper welcome with wines of all values.
There are existing patents that allow the addition of chemicals and cause the stoppers to expand. Gaseous agents and remnants thereof can make the liquids break down.
Any inscription or mark to be added to the stoppers can be done during molding and not as a separate process.
A demand exists for synthetic bottle stoppers which perform in the same manner as cork. Unlike cork, the present invention can be easily removed with minor back and forth motion with the first and second fingers. Prior art has the disadvantage of being difficult to remove.
The present invention solves the problem by providing a bottle sealing device having the characteristics previously described above.
With a bottle sealing device made of silicones or materials with similar characteristics as described in the attached claims, the problem is solved.
The present invention will be further clarified with references to the drawings.

The present stopper invention is made of silicone which has the mechanical characteristic of being able to maintain its' original molded shape after each mold compression.
Silicones are the preferred material, but may be molded with other materials that may be discovered to have the same characteristics. Example of silicone preferred is RHODORSIL
This type of silicone can withstand cold to −65 degrees (F) and also heat up to 400 degrees (F) and is approved for food contact.
The method to manufacture the present invention stopper is as follows: 90% of silicone is added to 10% of hardener and then mixed. This combination is then placed into an injection mold until the molding process is complete. Each cycle takes approximately 35 seconds. The injected material is water cooled. The stoppers are molded under 125 tons of pressure. The use of a blow mold is also possible.
The present invention can change with the addition of various different pigments or silica flecks that will alter the visual effect for greater desirability. These custom colors, when added, cause no deterioration of the stopper.
