My invention relates to closures for aspi rating bottles andthe like, and has for its principal object. the provision of an improved cap and closure construction by meansof which leakagecf fluid from the bottle may be insured against and at the same time the cap, which is usually of metal, may be protected from the fluid in the bottle.

It is also a purpose of this invention to provide a device of thischaracter in which the different parts thereof may be readily separated and cleaned or sterilized independently of each other.

Another and more specific object of the invention is to provide a closure for bottles of the character above referred to, in which a combined rubber stopper and metallic cap are used in such a manner as to enable one to readily open the bottle by unscrewing the cap and to carry the bottle from the same cap by means of a handle co-operating with the cap.

I will describe one form which the invention may take, by reference to the accompanying drawings, wherein,

Fig. 1 is a top plan view of the bottle closure; and

Fig. 2 is a vertical section on line 2-2 of Fig. 1, showing the closure applied to a bottle. I

Referring now in detail to the drawings, I show at 5 a suitable bottle such as is used by embalmers for an aspirating bottle. This bottle has a wide mouth, and, owing to the nature of the fluids which are in the bottle at various times, it is necessary that an exceptionally tight closure be provided therefor if any degree of cleanliness 1s to be maintained. 1

Heretofore, in order to obtain the tight closure necessary, metallic caps have beenused in conjunction. with rubber gaskets or rings to preventthe escape of the liquid from the bottle. However, these devices present one difliculty which mypresent invention is designed to overcome. This ditficulty lies in the fact that the fluids are permitted to contact with the metal at some part or other of the cap, and a cap of this 1929, Serial No. 379,73-L- nature, being provided with a. recess where. it fits over the bottle, is naturally veryhard; to clean, and. if the fiuidwithinthe bottle attacks or corrodes the metal, it becomes; 'a rather unsanitary and unsightly device.

In order to; overcome this, In, provide," in the present invention, a 1 stopper 6', which is: in the nature: of :a ,heavy I rubber, stopper, PRO: 1 vided in the center-with an aperture at:7fto} receive the usual 7 'aspirating stopperrforr ai 601 common, rubber closure. stopper, such as shown. at 8. The stopper; 6", it, will. be: noted, tapers slightly from top to bottom asl. shown at 9, and is provided at'it's top Withlad laterally extending; ledge, or--sl'1oulderf 101 Which rests uponthe top ot the bottle neck. Thus the rubber stopper, when fitted or down. within the bottle neck, forms as doubler-seal, one portionrofwhichfis located within the bottleneck, as at 11, and the other portion 7a of which is'between thew portion-110 of the. stopper andrthe topof thebottleiineck, as" at 12. VI'n'orderto hold the rubber member; 6 ti'ghtlyfinplace, It provide a cap;13-,- which is screw-threaded upon: the neck of the hot tle and iszprovided-at. its top with an in; wardly extending flange: 1 1' that :is adapted; 'tofit down upon theito'p ofztheL-memberi 6, so that,zas the cap 13ris screweddown-on: thebottle, it will force the-member 6* into; so, the'bottle neck'until the shoulder. lOrpressesa tightly againstthe top of the bottle. I

To,make he capeasy to turn,:I- providethe vupwa-rdly extending ears 15 and 16 at diametrically opposed points, so: that .:these ears mayreadilybe grasped by the 'hand of the person using the bottle in -order to turn theca-p, -As aturther feature'of advantage, I: pro vide, at the base of these ears, suitablere1 cesses, such asshown at. 17, to'receive the handle 18 and pivot'it to the'cap'; Theihans dle -18, being'iconnected in this tashion,v

It is highly important in devices of this character that a positive air seal be maintained regardless of whether avacuum or a high pressure is created in the bottle. With'the present invention, the stopper 6 and flange 10, both contacting as'theydo with the bottle mouth and being pressed tightly into position by the cap, make a 3. A closure holding and bottle carrying vdevice for aspirating bottles having a wide neck and a flexible stopper therefor which has a shoulder overlying the "neck of the bottle comprising a cap having a rim portion fitting over the bottle neck and having screw threaded engagement therewith, a flat annular flange extending inwardly from said rim a distance slightly greater than the wall thickness of the bottle neck whereby to secure said stopperand protect the neck of the bottle, said flange having upstanding ears thereon and a handle pivoted in said ears.

Inwitness whereof, I have hereunto subscribed my name this 26 day of .June, A. D.

positive seal so that gaseous or liquid matter in the bottle cannot escape. When a vacuum is created within the bottle, the cap gripping I the flange 10 prevents the rubber stopper 6 from being: drawn down into the bottle.

Also in case of high pressures within the bottle, the cap prevents the stopper from being: forced out of the bottle.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: I

1. A closure device forbottles and the like comprising a'resilient stopper having a portion for fitting tightly in a bottle mouth and an annular flange for engaging the top of the bottle whereby to form anadditional seal therefor, and a cap for holding said stopperin place having an annular rim for fitting down over the top of the bottleand a flange extending inwardly from said lrim to engage the top of'said stopper, said rim having means cooperating with the bottle mouth to clamp said cap tightly thereon,

saidcap having upwardly extending ears.

thereon adjacent the periphery thereof to aid in attaching or removing the same, and

' a bail-like handle pivotally mounted in said ears for carrying the bottle. 2. .A closure combination for aspirating" bottles comprising'fa. cap member having an annular rim provided with means to'receive' the neck of the bottle and means cooperating, therewith to draw the cap down on the bot- I tle neck, said cap having an inwardly extending flange extending over the bottle neck, a rubber closure having a substantialflpor-r tion fitting-within the bottle neck and having a projecting shoulder gripped between I the top of the bottle neck and the flange whereby to prevent the fluid contents of the bottle from reaching the cap, said closure, having an opening vinto said bottle spaced
