CLOSURE FOR JARS, BOTTLES, AND OTHER RECEPTACIi-ES.

Application led J'uly 5,' 1917, Serial No. 178,597.

T 0 all whom t may concern:

Be it known that we, ALFRED INGRAM and HARRY INGRAM, citizens of the United States, and residents of Brooklyn, in the county of Kings and State of New York, lhave invented certain new and useful Im provements in Closures for Jars, Bottles, and other Receptacles, of which the following is a specification.

l lhe invention pertains more particularly, although not exclusively, to closures of the screw cap type adapted for sauce and catsup andA other receptacles. y

We present our invention as embodied in a screw cap comprising a threaded barrel portion and a top portionvhaving a depending central part bearing'on its side a gasket, said depending portion and gasket being adapted to be forced in the mouth of the receptacle so that the gasket may seal against the inner upper edges of said mouth. We preferably form a groove around the upper inner edges of the barrel portion of the cap to receive the outer peripheral edges of the top of the cap, there preferably being a loose connection between said barrel portion and said top so that when the barrel portion is screwed downwardly upon the the edges of the bottle mouth, said top may have a direct downward movement without rotating while the barrel portion is being screwed downwardly to effect a tight seal. The gasket is of special construction in that it is a ring or band of rubber or other suitable packing material having a liat upper edge, a flat inner wall to engage the depending portion of the top of the cap, and an outer surface which is in part parallel with the inner surface of the ring or band and has an inwardly beveled lower edge portion to engage the inner-edges of they mouth of the bottle. l p kThe invention will be fully understood from the detailed description hereinafter presented, reference being. had to the accompanying drawings, vin which:

Figure 1 is -a vertical section through a portion of the neck of a bottle with the cap ofv our invention applied thereto 'preparatory to being screwed downwardly upon said neck so as to seal the bottle;

away and partly in section, of the neck of the bottle, with the cap of our invention screwed downwardly thereon and sealing the mouth thereof;

Fig. 3 is a bottom view ofthe cap detached from the bottle, and

Fig. 4 is a central vertical section through a modified construction of the cap.

In the drawings, 5 denotes the neck of the bottle, 6 slightly conveXedinner edges around the mouth thereof, 7 a screw thread of usual character formed directly upon the neck of the bottle, bottle, and 9 the cap of our invention.

The cap 9 comprises a cylindrical or barrel portion 10 grooved in its lower walls, as at 11, to engage the thread 7 formed on the neck of the bottle, a top 12 having a depending central portion 13 and a gasket 14 applied upon the exterior sides of said depending portion 13. The top 12 is of disk outline, and at its peripheral edges is held within a groove 15 formed by Hanging the upper edges of the barrel portion 10 outwardly said edges of the top 12. The barrel portion 10 and top 12 will preferably be formed from sheet metal and the connection .between the barrel portion 10 and top 12 will be suiciently free to permit the barrel portion 10 to be screwed upon that ordinarily when the gasket 14 engages the edges 6 of the mouth of the bottle, the resistance created against rotary motion of the top will? result in the further downward movement of the barrel portion 1() exerting a direct downward vpull on the top 12 so that the central portion the gasket 14 may move the mouth of the bottle without being caused to rotate within said mouth. The depending portion 13 of the top 12 is cylindrical, and upon the sides of saidportion a gaskety 14 which is of special character andextends from the lower surface of the top 12 to about the lower edge of the depressed portion 13. 14 is a continuous ring or band of rubber or other suitable packing material v4and vhas an inner flat wall engaging the wall of the depressed portion 13, a flat top edge to engage the surface of the top '12, a n upper below and thenv inwardly overy 8 the contents of the 13 of saidtop and downwardly within The Agasket anda lower inwardly and We revouter flat surface, downwardly beveled surface 16.

i gard the form of the gasket 14 of considerable importance in respect to its efficiency diumA will be also under in creating a proper inner seal and also in that when the cap is screwed downwardly upon a bottle neck the lower edge of the gasket may readily enter the month of the bottle and said gasket, above its beveled portion 16, may afford a proper sealing shoulder to firmly seat against the inwardly curved edges at the mouth of the bottle, the parts Ataking the position shown in Fig. 2 after the cap has been screwed downwardly upon the neck ofthe bottle. The eliciency of the gasket 14 as a sealing readily apparent from an inspection of Fig. 2, in which it may be seen that the surface 6 at the mouth of the bottle and is pressure against the sides of the depressed portion 13 of the top and also againstk the' lower` surface of said top ad? jacent to said portion 13.

The construction of cap shown in Fig. 4 differs from the caps shown in Figs. 1 and 2 in that it is formed in one integral piece of metal or other suitable material in lieu of having the top in vseparate pleces, with said skirtor barrel portion rotatable around/the top portion. n Fig. 4 we number the cap as a whole 20, and said cap comprises the skirt orr b-arrel portion 21 to be connected with the neck of a bottle, a top 22 havinga central depending portion 23, and a gasket 24 applied upon the side of said depending portion 23 and being of exactly the same character and shape as the gasket 14 hereinbefore speciically described. The part 23 of the top 22 corres onds with the portion 13 of the v top 12. he construction shown in Fig. 4 will, therefore, be fully understood without further specific description.'

e have shown and described preferred embodiments of our invention without intending to limit the same unduly thereto, since we are aware that the cap may be variously modied Within the scope and spirit of our invention. We, therefore, desire to claim the invention broadly.

at we claim as ourinvention and desire to secure by Letters Patent, isz'` 1. A closure comprising an exterior bar-l rel or skirt portion to pass downwardly over the neck of a receptacle, a top compris. ing a lateral portion extending annularly over the rim of the receptacle to said barrel portion and a depending central part adapt- IIlegasket is compressed against the closely encircling the p portion and extending from said lateral lportion to substantially the lower end of and skirt or barrel portions v s'aid depending 4. In combination with a closure therefor '..tion and said top being in independent parts interengaged at their adjoining edges and said barrel or skirt portion being rotatable around the outer edges of said top.

3. A closure comprising an exterior barrel or skirt portion to pass downwardly over the neck of a receptacle, a top comprising a lateral portion extending annularly over the rim of the receptacle to said barrel ortion and a depending central part adapte to pass downwardly into the mouth of the receptacle, and a sealing gasket side of said depending portion and having a fiat inner wall, a flat whose upper portion is parallel with said inner wall and whose lower ortion is bevel'ed downwardly and inwar ly. y

receptacle, a comprising an exteriorbarrel or skirt portion to ass downwardly over the neck of a receptacla, a top comprising a lateral portion extending annularly over the rim of the receptacle to said barrel portion and a depending central part adapted to pass downwardly into the mouth of the receptacle, and a sealing gasket closely encircling the side of said depending portion and having a downwardly and `inwardly beveled lower edge, said barrel or skirt portion and said top being in independent parts interengaged at their adjoining edges and said barrel or skirt portion being rotatable around the outer edges of said top, and said barrel portion and receptacle having interengafring portions for detachably securing the cllosure on the receptacle.
