Application led February 6, 1922. Serial No. stief To allwlwm z't may concern: l

Be it known that I, EDWARD BURNET, a subject of the Kin 'of Great Britain, residing in London, `ngland, have invented certain new and useful Improvements in Bottles and like Closing Devices, ofv which the following is a specification.

My invention relates to improvements in bottle and like closing devices that form substantially air and Huid-tight closures, and comprises a metallic cover or cap containing an elastic packing or washer that is presse-d and` retained against the mouth on the neck of` the bottle or other receptacle. It has for its object to provide a clos ing device o r stopper that will ermit of the withdrawalof the contents o a bottle without removal of the stopper, which is neat in appearance and hygienic.

The cover or cap of the improved stopper consists .of an end disc of aluminium or other suitable metal, having a central aperture and a depending flange or skirt, the diameters of the a erture in the end or top of the cap an of the lumien of the bottle neck being preferably made the same. Interposed between the inner or lower face of the top of thepcap andthe mouth of the bottle is a packing` piece or washer which consists of a comparatively thick disc of spongiose rubber between two thin lay'- ers of ordinary impermeable rubber. The washer and cap of the stopper may either remain separate or unattached, or the washer may be secured tothe inside of the vcap by means of an appropriate adhesive agent.

When a stopper is placed on theqnouth of the bottle it is kept pressed tightly against it while its skirt 1s made to fit around the neck of the bottle by applying pressure` by means of any suitable appliance, to the Wall of the skirt. Alternatively, the skirt may be formed with a screwthread for engagement with a corresponding thread moulded on the bottle neck.

The improved stopper Ais particularly suited for use with bottles containin vaccine, which can be extracted fromA inside the bottle by puncturing, with the needle of a h podermic syringe, the' portion of the was ier exposed within the a erture of the cap, the spongiose disc face tom with ordinary rubber ensuring that all punctures will be Seli-closing on the withdrawal of the needle.

The invention will be further described with reference to the accompanyin drawings, in which Fig. 1 is a section o a portion of a bottle, drawn to an enlarged scale and havin preferred` orm apphed to it. Fig. 2 is a similar view showing the stopper in another form and screwed on the neck of the bottle, and Fig. 3 is a 'section showing the cap and the associated washer before it is compressed by pressing the cap on to the neck of the, bott e. In the several ligures corresponding parts are indicated bythe same letters.

In the drawings a denotes the upper lportion of a bottle, bis a metallic cover or cap having a central aperture b and a flange or skirt' b2. Nested in the anged cap is an elastic packing or washer consisting, as depicted in F ig. 3, of a layerI yor disc of spongiose rubber c interposed between two discs c, c2 of ordinary impermeable rubber.

top and botthe improved stopper in its' In Fig. 1 the lower edge b3 of the skirt b2 has been bent by Spinnin and made to lit under the lip or rim a o the bttle.

In Fig. 2 the skirt b4 is formed with a screwthread and is engaged with? screwthreads a? on the bottle neck.

.Having thus described the nature of the said invention and the best means I know of carrying the same into practical eiect, I

claim 1. A bottle stopper comprising in combination a metallic cap consisting of a flat top portion having a central aperture and adepending skirt .embracin the' bottle neck, and an elastic washer oused within the cap and interposed between the neck of the bottle and the underside of the cap top, said washer consisting of an upper and a lower disc of impermeable rubber and a disc of spongiose rubber interposed between the said upper and Alower discs.

2. AA bottle 'stopper comprising in combination a metallic cap consistingof a fiat top portion h'wing a central aperture and a e pending skirt embracing thehbottle neck, and an elasticwasher housed within the cap and inter osed between the neck of the bottle an the under side of the cap top, said washer consisting `of an upper and a lower disc of impermeable rubber and o EDWARD BURNET.
