CASPER E. BLANCHARD, OF CHICAGO, ILLINOIS.

vBOT'ILE-CIJOSURE.

Be it known that I, CASPER E. BLANCHARD,

a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a new' and useful Improvement is Bottle-Closures, of which the following is a full, clear, and exact description.

My invention relates to improvements in bottle closures, and it consists in the combinations, constructions, and arrangements herein described and claimed.

The present invention is designed to be an improvement over that disclosed in my prior application, Serial No. 343,779fi1 ed Dec. In said prior application a bottle closure was disclosed which was submitted in the neck of a bottle and which was designed to betorn when an attempt to remove the closure was made, in order to prevent the refilling of the bottle or the replacement of the closure without detection.

An object of my-invention is to provide a bottle closure which does not require to be cemented in the neck of a bottle, but which when inserted in the neck will, owing to its peculiar structure cling to the neck so that when an attempt is made to remove the closure, it will tear.

A further'object of my invention is -to provide a device in which the closure has a body portion and a cap with a metal cover plate, which not only protects the cap but also secures it to the body portion ofthe closure.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularl pointed out in the appended claims.

Bly invention is illustrated in the accompanying drawings, forming part of this application, in wh1ch-.-

Figure 1 is a section through the neck of a bottle showing the closure in its normal position before being cut.

Fig. 2 is a section through the closure with the cover and ball valve removed. v

Fig. 3 is a section through the cap.

'Fg- 4, s a plan view of the cover.

Fig. 5 is a section* through the cover in perspective.

Fig. 6 is a section through the neck of the bottle, showing portions of the closure removed, and the liquid flowing out of the bottle. l

In carrying out my invention, I provide a Patented Dec. '7, 1920.

Application lcd June 10, 1920. Serial No. 387,925.'

body portion 1 (see Fig. 2), having its outer wall substantially cylindrical in shape. v The closure is preferably made of rubber. The lower interior walls 2 taper inwardly, forming the passage ways 4 and 5, on which rests the ball valve 7, when the bottle 24, is in its normal upright position. Between the curved surface 3 and the top 8 of the body portion 1, I provide inwardly7 tapered interior walls 9, so that at the point 10, where the body portion 1 meets anv outwardly extending fiange 11, the rubber is the thinnest. At the end 21 of the passage way 5 of the body portion 1, the walls 22 are slightly fiared out and are also substantially thinner.

A cap 12 with upstandinglugs 13 has recessed portions14, extending from the .under side of the cap 12 to above the upper surface of said cap. I also provide in the cap 12 a lug 19 extending downwardly into passage way 4 of the body portion 1, said lug 19 having a recess 2O extending up into it from the underside.

A metal cover plate 15 has perforations 16 adapted to come Ain alinement with lugs A13, as shown in Figs. 1 and 3. The inwardly bent portion 17 ofthe cover plate 15 is substantially one-half the width of the flange 11. The diameter of the cover plate 15 is slightly greater than the outside diameter of the flange 11.

When it is desired to pour out somejof the liquid contents, the lugs 13v are cut off, so that the recesses 14 now become openings into the interior of the bottle. When the bottle is tipped, the ball valve 7 will roll down the curved walls 3, thus'permitting the 1 liquid 23 to flow past the valve seat 6 and edge of the metal cover plate 15 and pries.

upwardly, 'the closure will be torn at the point 10 so that the attempt to remove the closure will be easily detected.

I claim:

1. The combination with a cylindrical bottle neck of a substantially cylindrical resilient closure comprising a body portion having outwardly flaring relatively thin walls at one end thereof and being provided with a laterally extending flange at the other end thereof thejunction between the flange and the body portion being relatively thin, a cap arranged to abut the flange on said body portion, and means for securing the cap to the flange.

2. The combination with 'a cylindrical bottle neck of a substantially cylindrical resilient closure comprising a body. portion having outwardly flaring relatively thin walls at one end thereof and being provided with a laterally extending flange at the other end thereof, the junction between the flange and the body portion being relatively thin a cap arranged to abut the flangel .on said body portion, means for securing the cap to the flange, and a ball valve carried by the body portion on the interior thereof and adapted to be unseated when the bottle is tilted.

3. The combination with a cylindrical bottle neck of a closure comprising a substantially cylindrical body portion having flaring and relatively thin walls at one end of the body portion arran ed to engage the interior wall of the bottl, a laterally eX- tending integral flange at the other end of the body portion, `the junction between the flange and the body portion being relatively `thin, the interior walls of the body portion 4. The combination with a cylindrical` bottle neck of a closure comprismg a substantially cylindrical body portion .having flaring and relatively thin walls at one end of the body portion arranged to engage the interior wall of the bottle, alaterally extending `integral flange at the other end of the body portion, the junction between the flange and the body portion being relatively Athin, the interior walls of the body portion tapering inwardly from each end of the body portion, a valve seat formed bythe converging walls, a ball valve normally carried on said valve seat, a cap arranged to rest on said flange, Said cap having outwardly extending hollow lugs adapted to be cut off to permit the outflow of the 4contents of the bottle and the entrance of air and a cover plate having openings arranged to receive the upstanding lugs of the cap, the edges of the metal cover plate being bent around the flange for holding the cap to` the flange.
