Application died June 8,

To all whom it my COMQW/ti Be it known that l, FREDERICK G. Sunni; a citlzen of the United States, residing at Dallas, in the county of Dallas and State" of Texas, have invented certain new and useful improvements in Bottle Closures; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Th present invention relates to closures for glass receptacles and more particularly to closures of this type embodying a removable seal and a. perforated top employed in conjunction therewith.

The object of the present invention is to provide new and improved form of clo sure for glass bottles containing liquids or dry materials or mixtures of both which provides a hermetically closed seal for the bottle prior to the use of the liquid or substance contained therein and a perforated permanent top for the bottle which is exposed upon removal of the outer seal and which serve to control the removal of the contents from the bottle in the usual maer.

With this object in view the several tea tures of the invention consist in certain novel features of construction, combinations and arrangements of parts. hereinafter de-= scribed and claimed, the advantages of which will be obvious to those skilled in the art from the following description.

In the accompanying drawing illustrating the preferred form of the invention Fig. 1 represents a section in elevation of a bottle top havin the new form of closure applied thereto; F 1g. 2 is a view of the ordinary form of seal illustrating the maer in which the removal of the seal is initiated; Fig. 3- is a perspective view illustrating a further stage in the removal of the outer seal; Fig. at is a perspective view of the clo sure, ilnstratin the appearance of the inner perforate too alter the outer seal has been removed; ig. 5 is a bottom plan view of the inner perforated top before application to the bottle; and Fig. 6 is-a cross section in elevation of the'pertorated e present invention comprises essen tially an inner perforated cap and an outer seal which are so designed with res set to one another that they may be app ied will.

I to the end of a bottle hy a single crowning operation. With both seals in position the end of the bottle is hermetically sealed and the contents may be preserved for an indelinite period without deterioration. When it is desired to use the contents of the bottle the outer metallic seal is easily removed in a manner which will he obvious to those skilled in the art, exposing the inner perforated seal which remain permanently connected to the end of the bottle in such a manner as to prevent discharge of the contents except through the openings.

As indicated clearly in Fig.1, the bottle indicated at 10 is provided with a lip l2 about which the closure is locked. The

new closure comprises an inner cap 14: having perforations 16 in the end and pro vided with an inner sealing ringhl of compressible material, which formsa hermetic seal hetween the; cap and the ll of the hottle, as indicated in Fig. l. T e outer seal comprises a rin 20 of thin material having a tlap 22 locate centrally thereof and connected to the ring at one end. vThe ring, 20 encloses and holds in place a metallic dish 24 which overlies a compressible disk 26 of cork or similar material for sealing the end of a bottle. The inner and outer sealing caps may conveniently be made oi? aluminum or similar material in thin sheet form which may be readily applied to the end of the bottle and crimped about the lip 12 in the manner indicated in Fig. 1 without the necessity of two separate crowning tions. en both seals are in position, as indicated in Fig. l, the bottle or other container is hermetically sealed and the con tents are not adected by the atmosphere. When it is desired to use the contents, on the other hand, the ha 22 may be easily lifted. as indicated in ig. 2, and drawn hack, tearing the outer enclosin ring 20, as shown in Fig. 3. This permits the removal of the entire ring 20, releasing the metallic dish 24 and compressible disk 26 to expose the inner seal it with its pertorated surface. The removal of the outer seal does not loosen or in any manner alicct the inner seal which remains permanently in position so long as the bottle is in use, the contents being discharged through the perforations in the surface in a manner which will be obvious to those skilled in the art.

too i ill?) opera- 9 This form of closn're provides a compact and relatively simple seal which has'exceptional advantages in connection with the bottling of vinegar and similar liquids, condiments, ground spices, toilet preparations,

powders, etc. In spite of the fact that the new form of seal provides essentially two y separate and complete closures for the com tainer it does not substantially complicate the application of the closure to the end outer sealing caps of a ummum or like material having flanges crimped about the lip to secure and hermetically seal the caps thereto, the outer cap being provided with a flap to facilitate its removal from the container and the inner cap being provided with perforations or openings through which,'the contents of the container may be discharged,

and a compressible packing member inter posed between the outer and inner sealing caps to hermetically seal the contents of the container when the outer cap is in position.

2. The combination with a container, hav ing a sealing lip adjacent the mouth, of an inner cap having a perforated top and a flan e crlmped about the lip, an outer seal. of thin sheet metal having a flange crimped to the lip about the outside of the first menla a tione'd flange and provided with a flap to 'facilitate the removal thereof from the container, a metal disk enclosed within the outer sealing cap and a sheet of compressible material underlying the" metal disk and engaging with the inner sealing cap and acting in tit? ible material interposed between the outer and inner caps to hermetically seal the contents of the container,

"41. The combination with a container of glass or similar material, having an annular sealing lip, of an inner perforated sealing cap of aluminum or like material having a flange adapted to be crimped about the lip of the container, a rubber sealing ring posed between the cap and lip of t e container, an outer sealing cap of aluminum or like material having a flange adapted to be crimped about the lip of the container outside of the inner flange and provided with a flap connected to the cap at one side, a thin disk enclosed within the cap, and a sealing disk of cork or like material underlying the thin disk and serving to hermetically seal the contents of the container when the outer sealing cap is in position.
