ALFRED INGRAM AND HARRY INGRAM, OF BROOKLYN, NEW YORK, ASSIGNORS To INGRAMS INCORPORATED, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

CLOSURE FOR JARS, BOTTLES, AND OTHER RECEPTAOLES.

Application filed September 8, 1919. Serial No. 322,401.

To all whom it 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, have invented certain new and useful Improvements in Closures for Jars, Bottles, and Other Receptacles, of which the following is a specification.

he invention resides more particularly in a .novel cap and container, the cap being of the so-called screw type and the container having about its neck ribs to engage lugs on the skirt portion of the cap, and the whole being of such character as to permit of the employment of a special gasket adapted to engage the exterior side wall of the container. Our invention provides a special construction of cap adapted to support in an annular recess formed therein the gasket, which will be formed of rubber or other packing material and preferably have in its initial form a downwardly and outwardly tapered lower edge. By prefertwo parts, one being a top disk and the other a band to engage the same, hold the gasket and afford the lugs which engage the rlbs on The cap may, however, be in one integral piece without departure from certain features of our invention.

The invention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which:

Fig. 1 is a side elevation of a portion of a container and of the cap of our invention superposed above the container and ready to'be applied thereto- Fig. 2 is a side elevation of the same,

showing the cap in sealing position on the container;

Fig. 3 is a corresponding view illustrating the method of removing the cap off the container, the lugs on the capwhich previously engaged the lower side of the ribs being shown in Fig. 3 as moving against the u per edge of said ribs for the purpose of ai ing in orcing the cap from the comtainer;

Fig.- 4 is an enlarged sectional View of a portion of the container and a portion of the cap and illustrating the parts as ready to be assembled;

Fig. 5 is-a corresponding view showing the cap as having been secured upon the container, with the gasket deformed against the outer surface of the container;

Fig. 6 is a central vertical section through the cap and gasket, the parts being shown in their initial condition and relation;

Fig. 7 is a corresponding View showing the cap as having been made in one piece;

Fig. 8 is a bottom view of the cap and is presented to illustrate the three lugs formed at the lower edge of the skirt of thgil cap to engage the ribs on the container, an

F ig; 9 is a top view of the container and illustrates the three ribs to be engaged by the lugs shown in Fig. 8.

In the drawings, 10 designates the receptacle or container, which may be a glass bottle or jar, 11 the cap for closing the upper end of the same and which cap will preferably be of thin sheet metal, and 12 a gasket which will preferably be in the form of a vertical band of rubber or other so I suitable packing material and have a down-.

wardly and outwardly. tapered lower edge 13, said gasket having a flat outer wall 14, afiat top edge 15, and an upper inner vertical flat wall 16. v

The container 10 is formed on the exterior of its neck portion 17 with three inclined ribs 18, these ribs preferably being of the same inclination and of the same length, and an open space being provided between the veiortical planes of the adjacent ends of the r1 s.

The cap 11 comprises a top 19 and a skirt portion 20 and preferably said top is in the form of a disk and said skirt portion 20 in the form of a band inwardly flanged at its upper edge, as at 21, to engage the top of the peripheral portions of the disk 19. The band 20 is suitably below its upper edge and above its lower edge formed with an. inwardly extending groove 22 which extends entirely around the band and affords a downwardly and inwardly inclined interior shoulder 23, this shoulder serving as a support for the gasket 12 and also creating an .annular recess or ket- 24 for said gasket. The lower edge of tl ie skirt portion of the cap or band 20 is formed with three equidistant inwardly pressed or extended lugs 25, the u-rpose of these lugs being, as will ap ear ereinafter, to engage the ribs 18.

n the assembling of the parts of the clo- 110 sure, the disk 19 is first applied to position against the flange 21 and the gasket 12 is then inserted partly within the pocket 24 encompassing the upper portion of the band or skirt 20, said gasket being initially somewhat tilted so that its lower sharp edge will rest on the shoulder 23 and a portion of its beveled edge overlie the edges of the neck of the container, as shown in Fig. 4, the gasket in this position not filling the pocket 24 but leaving a space in said pocket between its outer wall 14 and the adjacent surface of the skirt or band 20.

On the application of the cap to the container, said cap is pressed downwardly thereupon, the lugs 25 of the cap passing downwardly between the adjacent ends of the ribs 18, and the gasket 12 during this operation engaging the outer edges of the lip of the container and being by the container deformed outwardly to fill the pocket 24 and enter into sealing engagement with the side of the neck portion of the container, as

' shown in Fig. 5. After the cap has been applied upon the container by being pressed downwardly thereupon, said cap may be locked in position bybeing given a partial turn so as to carry its lugs 25 against the lower surface of the ribs 18, as shown in Figs. 1 and 5. The action of the lugs 25 and ribs 18 serve to tighten the cap in position and prevent any tendency of the cap losing its position by reason of accident or otherwise. The cap may be applied upon the container either manually or by mechanical means and whenever desirable the container and its contents may be subjected to the well known vacuum process. When the cap is merely set upon the container, as shown in Fig. 1, the air may be exhausted from the container and thereupon by mechanical means the cap may be driven downwardly on the container and then turned to carry its lugs 25 below the ribs 18. The effect of the pneumatic pressure in the vacuum sealing process will result in the top of the cap becoming dished downwardly, as we represent in Fig. 5.

' The arrangement of the ribs 18 and lugs 25 not only serve to aid in looking the cap on the container, but affords a further advantage in that, should the gasket be of a tacky nature and bind the cap and container together, the cap may be turned horizontally to a sufficient extent to effect the breaking away of the gasket from the container or from the cap before said capis caused to move upwardly on the ribs 18. If the cap and container should be fastened together by the tacky nature'of the gasket, it might be difiicult to move the cap directly upwardly, whereas under such condition the cap could be turned horizontally without particular effort, and in our arrangement of the ribs and lugs the cap may be turned horizontally for a definite distance before the lugs commence to ride upwardly on the upper surfaces of the ribs. When the lugs 25 are riding on the upper surfaces of the ribs 18, said ribs operate very much as wedges to force the cap upwardly. The ribs 18 are to be distinguished from continuous screw threads, and preferably only three of these ribs will be made use of. The lugs 25 are all on the same horizontal plane and coact simultaneously in their engagement with the ribs. While the closure may be classed as being of the screw cap type, it, as a matter of fact, dispenses with the ordinary screw threaded cap to engage a screw thread formed on the neck of the container.

In Fig. 7 we show a construction which is identical with that presented in Fig. 6 with the exception that the top of the cap is integral with the band or skirt portion there of instead of being in the form of a disk engaged by a flange on said band or skirt portion. When the top of the cap is in the form of a disk, as shown in Fig. 6, the disk may remain stationary during the rotation of the band or skirt portion, while in the construction shown in Fig. 7 the top and skirt of the cap must move together.

What we claim as our invention and desire to secure by Letters Patent, is:

l. A receptacle and a closure therefor comprising a top, a skirt portion to encompass the neck of the receptacle and annularly grooved inwardly suitably below its upper end to form a gasket supporting inset annular shoulder and above the same an annular recess for a gasket, and a gasket in said recess adapted to fill the same and to seal against the side of the neck of the receptacle and initially not filling said recess and having a downwardly and outwardly tapered lower edge a portion of which initially extends inwardly over the lip of the receptacle to be displaced by said lip into said recess, and said receptacle having on its neck and below its sealing zones corresponding inclined ribs which are laterally spaced apart at their adjacent ends and independent of one another and each having between the adjacent ends and below the upper plane of the ribs on the application ofthe closure to position and being adapted on the removal of the closure to leave the ribs they engaged and thereafter move to andride upwardl upon the upper surface of the adjacent ri s in series.

2. A receptacle and a closure therefor comprising a disk top to engage the lip of the receptacle and extend outwardly be yond the same, a skirt portion rotatable around said disk and to encompass the neck of the receptacle and having at its upper edge a flange extending upon said disk top and below its said u per edge an inwardly extending annular s oulder to support a gasket and form above the shoulder an an? nular gasket-receiving recess below the outwardly projecting portion of said disk top, and a gasket in said recess. adapted to fill said recess and seal against the side of the neck of the receptacle and initially not fill ingsaid recess and having a downwardly and outwardly tapered lower edge a portion of which initially extends in'wardly over the li of the receptacle to be displaced outward y by said lip into said recess, and said receptacle having on its neck corresponding inclined ribs which are laterally spaced apart at their adjoining ends and independent of one another and each having a clear vertical space above it extending to,

the top of the receptacle, and said skirt having inwardly extended lugs to engage said ribs, said lugs passing directly down between the adjacent ends and below the upper plane of the 'ribs on the application of the closure to position. and being adapted on the removal of the closure to leave the ribs they engaged and thereafter move to and ride upwardly upon the upper surface of the adjacent ribs in series.

3. A. receptacle and a closure therefor comprising a disk top to engage the lip of the receptacle and extend outwardly beyond the same, a skirt portion rotatable around said top and to encompass the neck of the receptacle and having at its upper edge a flange extending upon said top and being below said edge grooved inwardl to form an annular gasket-supporting shou der and above the same an annular gasketreceiving recess below the outwardly proj ecting portion of said top, and a gasket in said recess adapted to seal against the side of the neck of the receptacle, and said re ceptacle having on its neck corresponding inclined ribs in different vertical planes and which ribs are laterally spaced apart at their adjoining ends and independent of one another and each having a vertical clear space-above it extending to the top of the receptacle, and said skirt having inwardly extended lugs to engage said ribs, saidlugs passing directly down between the adjacent ends and below the upper planes of the ribs on the application of the closure to position and being adapted on the removal of the closure to leave the ribs they engaged and thereafter move to and ride upwardly upon the upper surface of the adjacent. ribs in series.
