To all whom it may concern:

Be it known that l, EDMUND HOFFMAN, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, county of Kings, State of New York, have invented a certain new and useful Improvement in Closures for Rece tacles, of which the following is a speci calDlOIl.

This invention relates to a metal closure for bottles, jars, metal boxes, or other receptacles, and the object of thisinvention is to provide a cap which can be readily applied by either hand or machinery,-and which will provide a positive and secure closure means under all conditions With this object, and other objects which may hereinafter appear, in view, I have devised the particular arrangement of parts hereinafter set forth, and more particularly 7 pointed out in the claims appended hereto.

eference is to be had to the accompanying drawing, forming a part hereof, in whichv Figure 1 is a side elevation, partly in section, of a metal closure, provided with my improvement:

Figure 2 is a side elevation, partly in section, of the upper end of a glass or like receptacle provided with my improvement; and

Figure 3 is a closure cap.

Throughout the various views of the drawings, similar reference characters designate similar parts. g

In the preferred embodiment of my invention, as disclosed in the accompanying drawing, 1 indicates a metal receptacle which 1s provided at its upper ede with strengthening bea 2, and

plan view of my improved w th a plurality of like su nce, these lugs 3 are formed integrally with the conta ne of spaced apart In 3. f'lhese lugs are elongated members an 0* are machinery, is all that position.

a container as disclosed in Figure 2. The closure ca is indicated at 6, which is in this case provided with a dome and a continuous circumferential downwardly extending flange 8, said flange being provided with inwardly projecting lugs 9. These lugs 9 are preferably formed at the extreme lower edge of the flange 8 and are produced by forcing inwardly the metal of the flange 8. These lugs 9 are provided with rounded shoulders to aid them in passing under the lugs 3 on the container. There are preferably as many of these inwardly projecting lugs 9 on the flange 8 21s there are. the outwardly projecting lugs per end ofthe container It will also be noted that the spaces between the lugs 3 on the container are wide enough to permit the lugs on the cap to pass therethrough for the purpose of removing the cap when desired.

Intermediate the upper edge of the container l and the inner face of the cap is provided a washer or gasket 10 for the pur pose of sealing the'closure'when the cap is placed down upon the container. it will be described, the cap down upon its container, and it will provide an effective seal therefor without being rotated to place it in position. The lugs 9 on the flange 8 of the cap contact with the inclined faces a of the'lugs 3 on the container or receptacle, and are, expanded suficiently until they reach a point below the shoulder 5 on the lugs 3 when they snap into engagement therewith at the same time forcing the gasket or washer 10 tightly between the inner face of the cap 6 and the bead 2 or upper edge of the receptacle. To remove the cap it is sim ly necessary to rotate the same until the ugs 9 on the flange 8 come into registration with the spaces 11 intermediate of the lu s 3 and the can can then be lifted ofi.

t will be noted that in View of the fact that the cap can be placed upon the container without the necessity for rotating the cap, it can be placed upon the container by as a simple downward pressure is required to place the cap in hit will also be seen that the only contact of the Han e 8 with the container is at the points w ere the inwardly bent lugs 9 contact therewith. The cap 6 is preferably made of a resilient metal so that while the same is being placed in position on the reprising a receptacle having a to be spaced away ceptacle and the lugs clined surfaces t of the lugs' 3, these parts of the flange 8 situated intermediate the lugs 9 can distort slightly to permit the lugs 9 to pass over the lugs 3 without excessive strain on the flange 8 of the cap. The parts of the flange 8 situated intermediate of the lugs 9 being spaced away from the container, permit this temporary distorting of the flange and the resiliency of the cap causes the flange to spring back into itsnormal circular shape the moment that the lugs 9 snap into position below the shoulders 5 on the lugs 3. i

In Figure 2, I have shown the device as applied to a glass or earthenware jar or receptacle, which operates in substantially the same manner as in connection with a metal closure as above described.

From the foregoing it is obvious that my invention is not to be restricted to the exact embodiment shown, but is broad enough to cover all structures coming within the scope of the annexed claims.

Having described my invention, claim is: v

1. A device of the class described complurality of spaced-apart lugs on its outer face and adj acent its upper end, a closure cap hav ng a continuous flange of a diameter adapting 'it from the sides of the receptacle, and having a plurality of spacedapart inwardly projecting lugs formed by forcing inwardly portions of the flange. and

a. sealing gasket spaced between the upper and the cap, the lugs arranged with respect container whereby the lugs on the cap may be caused to ride over the lugs on the container and engage beneath the same and the gasket compressed,

end of the container on the cap being so to the lugson the by direct downward pressure and the cap may be removed from the container by rotary movement.

2. In a device of container having a the class described, a plurality of outwardly projecting spaced-apart lugs on its exterior face near its upper edge, said lugs having inclined faces, and a closure cap provided with a continuous flange having a plurality of inwardly extending lugs adapted to slide over said inclined faces and enage beneath the lugs on the container when the cap s forced directly downward, said lugs on the closure cap being of a width to permit them to pass between the spaces separating the lugs on the container, whereby the cap can be removed by a rotary move,

ment which brings he liigs on the cap in 9 are riding on the in-' what I aeaeae alignment with the spaces between the lugs and also 7 prising a receptacle having a pluralityof spaced-apart lugs, said lugs being provided with inclined faces, a closure cap having a continuous flange of sufficient resiliency to permit distortion, said flange being provided with a. plurality jecting lugs adapted to ride on the inclined faces of the lugs on the receptacle and enof inwardly progage beneath the lower edges of said lugs 1 when the capis forced downwardly by direct downward pressure, said lugs on the receptacle being situated at spaced-apart intervals whereby the closure cap can be ro-, tated to bring its lugs in registration with the spaces located between the lugs on the receptacle and the lugs on the cap can be moved through said spaces Q 5. A device of the class described com prising a container having a plurality of spaced-apart lugs outer faces, a cap having a downwardly extending continuous and resilient annular flange capable of being distorted, portions of said flange at the lower edge thereof being inwardly bent to prov de a plurality of spaced-apart lugs on the flange, said cap being capable of being placed on said container by direct downward pressure and removedby a rotary movement, the flange on said cap having those portions situated intermediate of its lugs spaced away from the sides of the container, the lugs on the flange being adapted to pass over the inclined faces of the lugs on the container and engage beneath the same when the cap is forced downward by direct downward pressure whereby temporary distortion of those portions of the flange located between the lugs thereon is caused during such down ward pressure on the cap.
