MARIO GIANINI, or new YORK, N. Y.

CLOSURE FOR CONTAINERS.

Application filed October 11 1922. Serial No. 593,700.

To all whom it may concern:

Be it known that I, lVIARIO GIANINI, a citizen of the United States, and a resident of the borough of Bronx, county of Bronx, city and State of New York, have invented certain new and useful Improvements in C10- sures for Containers, of which the following is a specification sutficient to enable those skilled in the artto which the invention ap-,

pertains to utilize the same.

lVhile applicable to containers for commercial commodities generally, my improvements are deslgned more partlcularly for use in conjunction with the glass or ceramlo jars in which various confections are packedfor the market, and especially those of the class in which hermetical sealing is a desideratum; and the invention consists primarily and essentially in the use of an interior supplementary closure disc nterposed between the contents of the package and the" exterior cover or capthereof, substantially in the manner and .for thereasons hereinafter fully set forth. I

In the accompanying drawings 1 'illus trate a practical embodiment of the 'essen-.

t al features of my invention in conjunction with well known types of containers, al-

though I do not limit myself to the identical form and construction of parts shown,

since various modifications in minor details and mechanical expedients maybe resorted to with like result, and without departing from the spirit and intent of my invention in this respect. 1

With this understanding, I Fig. 1. represents a central vertical section of aglass jar or container such as used in the packing of hard candies for commer- =cial purposes;

fl- 15 a p view of such a container,-

without the closure means;

F'g. 3. 's a view similar to Fig.1'2g-with my auxiliary scaling disc in-position;

Fig. 4. is a top view of said-auxiliary sealing disc:

Fig; 5. is a section thereof,

7 taken upon plane of line 55. Fig.4;

Fig. 6. is a central vertical'sectional View; of the upper portion of a cylindrical container. illustrating a. modification in the 'construction. the closure means being omitted-y Fig. 7. is a top view-of the container shown in Fig. 6, also without-the-closure means;

Fig. 8.11s a view similar to Fig; 6, illus--- trating anothermodification in the construc- I known device of tion of-the neck of a container of well known ype; i Fig. 9, is a section of the top of a showing still another modification.

herein exemplify my improvements as adapted to gla'ssjars or containers used for thepacking of so called hard candies, to' which'class of goods my improvements are especially applicable, although, asbefore intimated, I do not limit myself to'this nor to any other type of jar, nor to the packing of any particular commodity,the invention-relating to the sealing means exclusively. Thus, C, represents a container of any well known or desired configuration, formed of glass, ceramic or other material, as may be found most expedient and appropriate forth'e-character 'of the goods to be packed for the market,glass jars being preferable and analogous The. outer cover'or cap K, is also of secondary importance in that any desired or well this character may be used in: conjunction with my inner 0r auxiliary closure disc A, as for instance a gasket-cover such as shown in Fig. 1, and also applicable.

tothe form of jar shown in'Fig. 8, forced into place overthe peripheral edge of the jar; or a screw cap may be provided for as, in Figspti and 9, ofthe drawings. In either and any case the function of the exterior cover K. is essentially the same as heretofore known inutheart, and forms no part ofmy present invention. the I distinctive feature of i which is the aforesaid auxiliary "interior 'clo-- Sure disc A. inconjunction with means, for detachably SGCIUIIIQ' the same within the neck I of the jar.-substantially as herein set forth. l-Icretofore. in the packingofhardsugar can-dies in glass ars. it has been the-common practice tofill the neck'of each jar with a iecenftiss-ue or waxed paper or other suits; able material'. crushed (without unnecessary compression) into the form of atstopper or wad W, and interposed between the goods and the inner side of the cover; and the packinfgis' usually done by unskilled labor. Under ordinary conditions, the most important consideration in the packing of hard candies, in jars is to accomplish the tenance of such Qoods'in perfect condition, as bfvv the' hermeti'cal sealing thereof. This :same in such manner as to insure the main 1 can-be accomplished bythe use of various 3 styles of caps and closures in a manner, and

of'sealing' lugs c, 0, may,

by satisfactory method, however, being that. of vacuum SQdlID In every instance, the wad.

or stopper WV, of crushed waxed paper, or Y equivalent, is resorted to, because without 1t,,,

it would be diflicult and practically impossi-- ble to compactly fill the jar with hard cairdies up to the level of the cover, owing to their shapes and unwieldly, friable character,-so that the omission of said filler wad. or stopper WV, would result inthe movement; of the candies as related to each other in.

the jar, especially during transportation, the-.

disturbance and shaking about of the com-- ponent parts of the contents of the jar thus; involved tending to break or mar the dies superficially, destroying the initial. gloss,'and'resulting in a dusty appearance,

before the goods reach the retailer or cus-- stopper W,

"be hermetical on account thereof, so that: in course of time the inlet of air into the jar will impair the appearance, and causethe deterioration of the candies thus 1m perfectly packed, rendering the goods 'un-- marketable. 4

By my invention I obviate this difficulty and danger by my auxiliary sealing disc A,

because its use necessitates the properpositioning aud compression of the wad W, therebelow, and precludes the possibility of any" portion of said pad interfering with or im'-' pairing the perfect and satisfactory closing: and sealing of the outer cap or cover K.

Myauxiliary closure disc A, is preferably, althouglrnot necessarily, seated on an .m-- ternal annular shoulder a, mouth or neck'of the jar'or container C, as. illustrated in Figs.'1,2 and .8, of the drawings, although in lieu of the said annular shoulder c, a plurality of spaced apart sections thereof, or supporting lugs or shoulders 0, may obviously dicated particularly in ings.

hOWGV1,l)Q dlspensed with in certain cases if preferred, an il my auxiliary closure disc as it were, directly on the top of the filler or wad TV, as indicated in Fig 9,"of the d raw ings, the really indispensable parts in this respect, being the plurality of spaced apart disc-retaining lugs or shoulders c", formed internally on the neckof the jar C, for en'- gagement with the upperperipheral edge of said auxiliary closure disc A,- the latter bespaceding; formed with correspondingl means, well known in the art, the most through carelessness, will.

fOI'lTlQd in the be substituted, a's'in' Fig. 6', of the draw The sealing shoulder a, or plurality A, may be seated,

apart peripheral notches a, a, adapted to fit over said retaining shoulders 0", 0*, for the purpose of applying or removing the said disc A. That is to say, the disc may be ap disc A, being rotated when thus applied to bring the peripheral edges a, 64, thereof between the notches a, a, into engagement with the under sides of said retaining shoulders and thereby locking the disc A, in position, .as shown in Figs. 1 and 3 of the drawings.

Any desired plural number of these .notches a, a. and retaining shoulders 0 0", may be provided for the purposes of thus detachably locking my auxiliary closure disc in position, three being a preferable number in this respect, as shown in the accompanying drawings, as attaining the desired result in a simple and effective manner.

My auxiliary closure disc A, may be made of parafiined card-board, or other fibrous or textile material, or of tin or other sheet metal, or in fact of any composition or material'afiording the requisite degree of per-- manence in shape.

In order to facilitate manipulation thereof, I form my auxiliary closure disc A, with finger butments or bearings a*, a, which may be grasped between the thumb and indeX finger nailsfor the purpose of applying 7 or removing the disc, or turning it axially as related. to the retainer shoulders c", 0*, of the jar. I 1

My auxiliary closure disc A, embodies a double function, in that it not only answers the purpose of a supplementary seal as here inb'efore set forth, but also affords a convenient means of closure after the removal of the outer cap 'or'cover K, which is usually so bent or damaged in effectingthe opening of the jar as to be practically useless, as a means of proper closure thereafter. Of course where screw caps are used as a means of external closure, the same are not usually damaged by removal; but nevertheless, even in such'cases my auxiliary closure disc affords a convenient means of protecting the contents of the jar in the absence of the outer cover.

What I'cla-imas my invention and desire to secure byLetters Patent is,

actersdesignated, a jar formed witha plu- "1. In closures for containers of the char.-

rality of spaced-apart inturned retaining shoulders in the mouth thereof, and an auxiliary closure disc fitting within the mouth of the jar and formed with a plurality of peripheral notches cooperating with said shoulders, and with manipulative finger contact shoulders, substantially in the manner and for the purpose-set forth.

3. In closures for containers of the character designated, a jar formed with discsupporting means and a plurality of spacedapart inturned retaining shoulders in the mouth thereof, and an auxiliary closure disc fitting within the mouth of the jar and formed with a plurality of peripheral notches cooperating with said shoulders, substantially in the manner and for the purpose described.

4:. In closures for containers of the character designated, a jar formed with discsupporting means and a plurality of spacedapart inturned retaining shoulders in the mouth thereof, and an auxiliary closure disc fitting within the mouth of the jar and formed with a plurality of peripheral notches cooperating with said shoulders, and with manipulative finger contact shoulders,

substantially in the manner and for the purpose described.

5. In closures for containers of the character designated, a jar, the mouth of which is formed with a plurality of spacedapart inturned retaining shoulders and with a dis0-supporting annular shoulder, and an auxiliary closure disc fitting within the mouth of the jar and formed with a plural ity of peripheral notches cooperating with said shoulders, substantially in the manner and for the purpose described.

6. In closures for containers of the character designated, a jar, the mouth of which, is formed with a plurality of spaced-apart inturned retaining shoulders and with a disc-supporting annular shoulder, and an auxiliary closure disc fitting within the mouth of the jar and formed wth a plurality of peripheral notches, cooperating with said shoulders, and with manipulative finger-contact shoulders, substantially in the manner and for the purpose set forth.
