A li ation filed December 14. 1906. Serial No. 291,708.

To all whom it may concern:

Be it known that I, MAURICE HOFHEIMER, of the city of Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Closures for Bottles, Jars, &c.; and I do hereby declare that the following specification, taken in connection with the drawings furnished and forming a part thereof, is a clear, true, and complete description of the several features of my invention.

M said closures pertain to the class recognize as inside or throat sealing devices, as ished from the outside, or cap forms.

While effective as to the exclusion of air and the retention of liquids, my closures are not intended for, or capable of, resisting such high internal gaseous pressures as are incident to the use of certain well known throat sealin devices.

Alt ough embodiments of one or more of the features of my invention are widely applicable to various uses, and regardless of ordinary variations in the contour of the throats of jars or bottles, their prime value will accrue in connection with the marketing of natural waters in such large bottles as are usually employed, and also in the bottled milk trade withspecial reference to sterilized products, involvlng the use of quite wide mouthed jars or bottles, and requiring in their closures a practically total exclusion of air, a reliable retention of contents, and a capacity to be readily opened.

For securing the stated. results certain conditions are imperative, and these are provided for in my closures. in their simplest form, but for meeting many contin encies, the use of my closures embodying al of the severalxfeatures of my invention may be relied upon.

Considered structurally, my closures in their most complete form are novel in that they have an n wardly extended central cir-' cular boss whic is enlarged at its top; and also have an upwardly extended annular flange which is provided with an inwardly turned or beaded edge;-also, there is between the bpss and the flange an annular recess or space, not only for the reception of an annular tool for setting the closure in a jar or bottle, but also for the reception of the operating tip of a lever opener for removing the closure.

To more particularly describe my invention, I will refer to the drawings in which,

Figures 1, 2 and 3, respectively, illustrate one of my novel closures in its most complete form, in top view, in central vertical section, and as organized with a water Lottle, and, with a lever opener indicated in position for service. Figs. 4 and 5 illustrate a simpler form, respectively in top view and in central vertical section, and in which the edge of the flange is plain. Figs. 6, 7 and 8 illustrate my closure 1n its simplest form, respectively in top view, central vertical section, and as organized with a common form of milk jar. Fig. 9 illustates in section, one of my closures, a water-bottle head and a hand-setting-tool for seating the closure for service.

My closures are composed of any suitable material ca able of being worked into proper contact wit glass, but ductile sheet metal is well adapted to the purpose, referably aluminium, or quite light tin, and

they are molded into form or struck up by means of The closures A, A and A differ only as totheir embodiment of the features of my invention. As in Fi s. 1, 2 and 3, all have an upwardly extended and an upwardly extended annular flange b, terminating at its top in a circumferential edge b and the coincident surfaces of the flange and boss are separated by a properly proportioned annular space 0. These features are essential, and are often relied upon by me for assuring the main objects of my invention. The boss a, being central, and upwardly extended, has two functions: mainly, it afiords an exterior annular surface for reliable contact by the tip of a lever opener, partly overlying the flange, as indicated in F i 3, that closure being organized with a bott e B, so that in the act of o ening it may be lifted free from its seat, or t e side opposite the opener may be swung upwardly as indicated in dotted lines; secondly, the

interior recessed portion of the boss, serves central circular boss a,

to divert from the junction of metal and glass, the impact of liquid when filled bottles and jars are in transit by wagon or rail and subjected to violent rocking movement, because when the eontents are dashed sidewise and upwardly against the closure, they dash into the boss and then takings, ward direction, prevent undue impact at the closure joint, resulting in-a minimum tendency to leakage. The annular recess or space c has also two functions of equal imporlance, first, in affording access .for an annular setting tool (asindicated in Fig. 9) which, when properly manipulated, bears against the flange and forcesits outer surface into close engaging contact with the coincident glass surface of the throat of the jar or bottle; and secondly, said space. or

recess 0 afi'ords free access to an opener, as

hereinbefore indicated.

In some cases the surfaces of bottle throats are ground, so that an effective ongaging contact therewith is attained with a plain edged flange as shown in Figs. 4 and 5, but for use with unground surfaces I deem it wise, as a precautionary measure, to provide the circumferential edge or top of the flan e with an inwardly turned or reinforced e ge as at 1), Figs. 1, 2, 3 and 9, there being a slight space between the metal surfaces so that the setting tool, in forcibly. engaging with the turned metal, can safely drive the outer adjacent portion of the flange into an intimate contact with the nor mal glass surface, which is, of course, more or less irregular, in its contour, as compared with a ground surface whether the circumferential edge I) or top of the flange be of a single thickness of metal or reinforced,.it is susceptible of being worked into close and effective sealing contact with the lass regardless of the usual variations incldent to glass blowing and molding.

In such uses as may require a specially firm setting.of the closure, and involving corres ondingly greater force in opening, it is o importance to provide the boss'with an abutment (for contact with or by an opener) more reliable than is afforded by the plain annular exterior surface, and for meeting such contingency, I provide the top of the boss with a peripheral enlargement 0/, thus securing an effective overhanging shoulder.

"Referring now specially to Figs. 4 and ,5,

it will be seen that the closure A is provided with the boss aand its enlarged top or shoulder a and that it' has the annular space, or

recess 0. .v

In Figs. 6 and 7, the closure A. is in its simplest form, embodying the essentialfeatures hereinbefore referred to, 'i. e.-, the

vertically extended central'boss a, the-upwardly extended flange b, and the double -functional annular space or recess 0.

down- New referring. to the bottle heads and throats of Figs. 3 and 9, it is to'be understood that they illustrate an ordinary form of water bottle having a throat surface slightly inclined inwardlyi'rom the top, enabling an effective seating of the closure as indicated.

Should the throat be ground, a plain flange can be relied upon, but as hereinbeforc stated, the turned edge flange is better adapted for use in an unground throat, the setting tool (1 in either case requiring a downward thrust upon the bottom of the annular recess, with or without a slight rotative a slight gyratory movement of the setting tool while subjected to the thrusting action required as with the water. bottle.

The setting tool C should have a central recess and an appropriately dimensioned annular working face adapted. to snugly enter-the recess or space 0 of the closure, and

slightly tapered at the outer surface; it may be-composed of hard wood or of metal; it may or may not be vertically slitted to prowhich case a slight inward yield will be afforded, and hence its normal diameter may be slightly greater than when not so' slitted, and the tool in either form should be slightly rotated in the act of setting a closure, and in closing jars it should also be sli htly gyrated, as liereinbefore indicated. hould it be found desirable to providea special setting tool for milk jar service, well known expanding devices may be embodied therein for facilitating the operation.

I am aware from actual tests that if the outside of the flange and adjacent thereto be ,thinly coated with an odorless varnish, or paraffin, or even very thin paper, a specially tight joint will be secured.

Having thus described my invention, I

claim as new and desire to secure by Letters,

Patent,
