Holder for effervescent liquids

Abstract

The specification relates to the retention of carbonation of effervescent liquids stored in plastic bottles. The invention is holder that allows the plastic bottle to be held in an inverted position and forms a liquid seal between the threaded top of the bottle and the holder's threaded cavity.

Description

BACKGROUND OF THE INVENTION[0001]Effervescent beverages are very popular with consumers. Effervescent beverages are produced by dissolving a gas, typically carbon dioxide, into the liquid beverage. This process is often called carbonation. The use of low gas permeable plastics has allowed the packaging of effervescent beverages in plastic containers. Effervescent beverages are provided in a variety of plastic containers of different volumes. One popular size is the two liter bottle. Although popular, the two liter bottle once opened and recapped my lose carbonation or go flat before the entire contents are consumed. This invention relates to the improvement of the retention of carbonation of beverages or any effervescent liquid stored in plastic bottles.SUMMARY OF THE INVENTION[0002]The use of plastic containers to store effervescent liquids or beverages is an accepted practice. The retention of carbonation of an unopened container is sufficient for shipment, warehousing and retail ...

AI Technical Summary

Benefits of technology

[0004]Others have developed holders to keep bottles in inverted positions, however, these inventions are inferior because they do not address another cause for the loss of carbonation, that is the thickness of the cap. A tight seal between the cap and the bottle prevents loss of carbonation. However the gas can also simply diffuse through the plastic at the top of the bottle top and the cap. The rate of diffusion is dependent on the thickness of the material it must defuse through, the more material the less the rate of diffusion. Additionally, a sturdier cap will allow for more torque force to be applied to the cap / bottle top assembly thereby providing a better primary seal not possible with the original cap. Thus the disclosed invention improves the retention of carbonation by replacing the original cap with a holder that will screw on to the top of the bottle and keeps the bottle in an inverted position allowing the liquid to form a secondary seal. Additionally, a thicker cap provides a better barrier against diffusion and allows for more torque to be applied forming a tighter seal.

Problems solved by technology

Once the bottle is opened, however, the effervescent liquid may lose its “fizz” or carbonation before the contents are consumed.

One cause for the loss of carbonation is the failure of the seal between the cap and the top of opened bottle.

The replaced cap does not provide a sufficient seal to the top of the bottle, allowing the gas to slowly escape, thereby causing the effervescent liquid to lose its “fizz” or carbonation.

Inversion, however, is not practical without a holder for the bottle because the diameter of the cap is significantly less than that of the bottle allowing the bottle to tip over.

Others have developed holders to keep bottles in inverted positions, however, these inventions are inferior because they do not address another cause for the loss of carbonation, that is the thickness of the cap.
