METHOD OF CAPPING BOTTLES.

No Drawing.

To all whom it may concern:

Be it known that. I, JOHN WYSOCKI, a citizen of the United States, a resident of Brooklyn, in the county of Anne Arundel and State of Maryland, have invented a certain new and useful Method of Capping Bottles, of which the following is a specification.

This invention relates to a capping a bottle.

An object of the invention is the provision of a suitable method for forming a cap over the cork and neck of a bottle to rovide an air-tight closure of the same which may be readily removed when the contents of the bottle are to be used.

The invention may assume various'specific forms, and the following description constitutes merely a preferred embodiment of the invention. This composition in one of its preferred forms consists of 100 grams nitrocellulose such as pyroxylin, 500 c. c. ether, 500 c. c. absolute alcohol, 50 c. c. castor oil, 30 grams aluminum powder,

and a suitable quantity of a yellow aniline dye. This composition has been designed to provide a suitable viscosity so that the composition will spread uniformly over the surface of the bottle and dry to produce a very neat and glossy appearance. It will be understood that the proportions may be varied somewhat while retaining the desired viscosity and that equivalents may be substituted.

l The bottle to be coated with a cap is filled with the liquid intended to be marketed. the cork is properly inserted. and the neck of the bottle is then provided with a thin coat ing of vaseline, after which it is dipped into the above coating composition while the composition is being agitated by any suitable means in order to insure homogeneity. After each dipping-the coating formed on the neck of the bottle and over the cork is method of allowed "to dry before dipping for the next coating, and these dippings are then continued until acap of the desired thickness is obtained. In order to quickly dry the successive coatings. a gentle air blast having :1 temperature of 25 to C, is employed. The coating may be made very smooth and neat in appearance by dipping the neckof the bottle with the coating thereon into cool Application filed December 29, 1921. Serial No. 525,809.

- water for one or two seconds after each coating.

.Before applying the coatings as above described, there may be applied a sub-coating formed of a composition comprising the following constituents: grams nitrocellulose such as pyroxylin. 500 c. c. ether, 500 c. c. absolute alcohol, 25 c. c. castor oil, grams aluminum powder, and a suitable quantity of a yellow aniline dye. This coating provides a dull non-transparent basic layer containing a higher ratio of metallic constituent. The constituents of these coatings may be varied by substituting various cellulose esters or other preferably transparent or translucent coating material for the nitrocellulose, various solvents for the ether and alcohol, suitable softeners in place of cast-or oil, and other metallic powders and non-corrosive or tarnishing substances in place of the aluminum powder. Other suitable greases or oils may of course be substituted for the Vaseline as long as they will have the property of preventing too close an adhesion between the composition .and the glass.

While the bottles arebeing dipped. it is advisable to rotate them either by hand or by machinery so that the coating will be uniform in thickness. and this rotation may be continued after the bottle has left the coating liquid so that the latter will spread uniformly while drying.

As a result of the above described method of procedure. a bottle cap is formed over the cork and on the end of the neck of the bottle, which is air-tight. and not affected by atmospheric influences. that is. it will not tarnish or corrode. It may easily be stripped off because of the underlying film of Vaseline or' other greasy material, and it will resemble a metallic cap in many respects. The dye employed will color the entire composition so that the metallic particles will appear to be one continuous sheet of metal as the metallic'particles will reflect the color of the dye without being themselves colored. This will produce a uniform color without employing a colored metal or alloy of a destructible or nonpermanent nature.

As many apparently widely different embodiments of this invention may be made 2. The method of capping a bottle com- 15 prising applying thereto a solution having a viscosity enabling it to spread uniformly over the surface, this solution containing the following ingredients in the following approximate relative proportions: Ether, 500 c. 0.; alcohol, 500 c. c.; castor oil, 50 c. c.; aluminum powder, 30 grams; nitrocellulose, 100 grams.

In testimony that I claim the foregoing, I have hereunto set my hand this 5th day of 25 December, 1921.
