CLOSURE FOR BOTTLES AND LIKE RECEPTACLES Filed April 22, 1927 Patented July 30, 1929.
UNITED. STATES I 1,722,909 PATENT OFFICE.
EWALD GOIITSTEIN, OF BONN, AND EBEREARD MEYER, OF TROISDORF, GERMANY.
CLOSURE FOR BOTTLES AND LIKE BECEPTAGLES.
Application filed April 22, 1927, Serial No. 185,856, and in Germany May 1, 1926.
This invention relates to closures for hottles or like receptacles of the having a packing disc covered with an insoluble cuticle placed inside a metal capsule.
' The object of the invention is to provide a closure for bottles which will be absolutely ti ht.
another object of the invention is to form a closure which will be impervious to liquids and will not impart a taste thereto or be acted upon thereby.
The present invention consists in the improved bottle closure to be hereinafter described and more particularly pointed out in the claims.
The invention is clearly illustrated in the accompanying, drawings, in which F ig. l is a perspective view showlng a combination of the cuticle with cellulose cardboard, V
Fig. 2 is an elevational detail of modified form of the invention, and
Fig. 3 is a vertical sectional view embodying the combination of a metal capsule and pad. 7
According to. the present invention, each bottle closure is formed of which is fitted with a packing disc. composed of textile material or of paper, cardboard or like fibrous material and covered on one or both sides with an elastic cuticle.
By this means the bottle is hermetically sealed and the liquid comes in contact only with the glass and the cuticle. The cuticle must be so flexible and elastic that it will perfectly adapt itself tov the shape of the edge of the bottle mouth and for this purpose it is formed of nitrocellulose or its solution in volatile organic" solvents. The flexibility of the-nitrocellulose may be if required enhanced by the addition of a gelatinizing agent. I
The following may be taken as typical examples of suitable gelatinizing agents 1) Triacetic-ester of glycerine.
2 Tricresyl-ester of phosphoric acid. 3 Ethyl ester of phthalic acid.
By coating with such solutions extremely tough cuticles are formed on pads made oftextile materials or made of' paper, cardboard or like fibrous materials, which will provide .an excellent packing material.
The solution, when applied, penetrates the cardboard as if with a slightly a metal capsule of the capsules they may retain the form of a flat disc. If, however, they are made separately, it is necessary, in order that they may lie correctly in the capsules, either to coat them on both sides of the cuticle or to give them a certain curvature, as shown in Figure 2. This curvature makes it possible to introduce the discs correctly into the capsules by means of sorting machines.
In Fig. 3 there is shown another form of the invention and in reducing this feature of the invention to practice each bottle 1 is provided with a closure generally indicated by the numeral 2 comprism a metal capsule 3 which is fitted with a pacliing disc 4 composed of textile material of paper, cardboard or like fibrous material on both sides with an elastic cuticle 5.
Having now described our invention, what we claim as new and desire to secure by Letters Patent is 1. A closure for bottles and like receptacles, comprising a metal ca sule, a paid of artificially manufactured brous material inserted in said capsule, and an elastic cuticle composed of nitrocellulose attached to 'manufactured fibrous material coated wit an elastic cuticle composed of nitrocellulose.
4. Packing material for bottle closures and the like, comprising a pad of artificiall manufactured fibrous material coated wit an elastic cuticle composed of nitrocellu lose treated with a gelatinizing agent.
In testimony whereof we afiix our signatures.
