end. In the event-that a metal upper wall is provided cnthe container and a screwclosure formed, difficulty? hasbeen experienced inremoving the contents,; particularly: in cases "Where they havebecome caked or otherwise adhered together. In instanceswherein the entire head isremovabladifiiculty has been experienceddnproviding a-suitableseal-which will prevent the contents from sifting out in the eventthat -the container is placed upon its side. Also in most cases wherein a fullremovable head is provided; theclosure is damaged during its firstvremovaL and cannot-thereafter be replaced,- should: only a portion of the contents be removed in the first instance.

A container closure constructed in accordance with the present invention:- provides a highlyeffective seal, which, if desired may be made invention is to provide a, container having a closure head wh-ich maybe quickly-"- applied and locked-in closing relation, thus definitely pre venting loss of contents due to accidental opening. The: closure may, with equal facility,*-b'e removed and the contents taken-from the co'ntainer with ease, Whether such contents comprise comminuted material or are in one piece,a's-inthe caseof parafiine or other solids.

A further object-t the invention is to provide a closure'element for a container of the type described, which will strengthen the container andwiltincrease' its' effective life, permittin continued re-use.

tratedin'FiQ 9; Referring now tothestructure illustratedi'n Figs-:1 and 2, the container is of the general cylindrical type having. annularsid wallsl D which ma'yibe formed of heavy cardboard, fiber board oi' anylother suitable material, including-metal, plasno material," or otherwise. ,Thebottom closure 1 I is permanentlysecured to thecontainer and forms no part; of the present" invention At the upper end oi-the container, a continuous ring l2 of metal, or any other suitable material; is posi- 3- of the ring being planartionedi-the'upp'er edge with the upper edge Id of thecontainer.

A This -ring =is formedwith a upper edge I 4 ofthe of apertures IT,- and into threaded aperture lt in ring l2. Theshowing ofthe thickness ofsring [2 in Fig, 1 is, of course, exaggerated, although the in manyinstances wherein it is desired-"t0 provide additional reinforcement for-the upper-' endof the container, a rin wiformed of heavy 'gauge Except ierthe thickness metal may bedesi-red; of this ring, however, the diameter of the upper discharge opening of the container is the same as the diameter of the container. This would be otherwise if the side walls of the container were tapered, which construction is Within the scope of the present invention.

The top closure element 2| may be formed of metal, or any other suitable material, and around its marginal edges is formed with an upwardlydisposed flange 22 and a downwardly-extending 'plurality of spaced; threaded apertures 16' which are alignedwith apertures l l adjacent tothe container;- Aheaded screw it passes through each annular flange 23. A plurality of bayonet slots 24 are formed in flange 23 at points adjacent to screws l8. When it is desired to aflix the top closure to the container, the vertical portions of the bayonet slots are aligned with screws 15, the closure moved downwardly until upper flange 22 is in firm engagement with upper edges I3 and I4 of ring and container, respectively, the closure then rotated to a point wherein screws [8 are positioned at the inner end of the horizontal portions of the bayonet slots, and the screws then tightened.

The number of screws is also a matter of choice,

and in case it is desired to make the container substantially air-tight, more screws may be provided. Also, to further increase the sealing qualities of the container, any conventional, fiat,annular gasket of resilient material may be placed on the upper edge of the container before the closure is moved into place. This particular arrangement is illustrated in Fig. 3, wherein the annular gasket 26 is positioned on the upper edge of the container. In this instance, also, screws 18 carry relatively large, fiat washers 21 to further enhance the sealing qualities of the container closure.

In the embodiment of the invention illustrated in Figs. 4 and 5, the container is formed with the same spaced apertures I1 adjacent to its upper marginal edge; and inthis instance, the ring may be split, as illustrated at 31 in Fig. 5. The ringis formed with spaced apertures 32 which receive bolts 33, which may, if desired, be welded in apertures, as shown at 34, or they may be other wise secured. Bolts'33 are threaded,as shown at 35;"andfnuts 36 firmly secured downwardly-extending flange 23 of top closure 2| to'the side walls of the container. Annular flange23 of closure 2| is also formed with the same bayonet slots 24, and the closure is applied in the manner previously described, and when in place, nuts 35 are tightened.

v Themodified arrangement illustrated in Figs. 6, '7 and-8 includes the inner ring 40 having the apertures 4| therein, such apertures receiving hollow; bolt-receiving stud 42; In this instance,

ring 40 need not besplit, and the ring may first be inserted in the upper end of container l0, so that apertures 43 are alignedwith apertures I! in the container. Studs 42 are "formed with splines 45 which,when the studs are forced outwardly in apertures, cut keyways 46. This force-fit of studs 42 is sufficient to normally retain studs 42 in the ring;- and also prevent'rotation thereof. The closuremember 2| is formed as in the other embodiments of the invention, and'fiange 23 is secured against the side walls of container I0 by means of bolts 41 which are received inthe internally-threaded bore of'studs 42.

In the last form of the invention illustrated in Figs. 9 and 10, container I0 is formed with the usual apertures H. In this instance, however, the

continuous or split ring of the other embodiments is eliminated, and the closure disc maybe provided with an upwardly-disposed annular bead 5| around its marginal edge, such bead terminating in a downwardly-depending annular flange 52. At spaced points adjacent to the periphery of the closure element 50, there are secured, by means of welding or otherwise, a plurality of spaced angle brackets 53 having vertical portions 54, such vertical. portions having threaded apertures 55 therein which receive screws 56. In this instance, apertures 51 in flange 52 neednot be of the bayonet-type, since the closure member 5|] is adapted to be initially secured in place before the bolts 56 are screwed into the apertures 55. After the closure is properly positioned, the screws are moved into the apertures, as shown in Fig, 9, and the container is ready for shipment,

While four forms or embodiments of the invention have been shown and described herein for illustrative purposes, and the construction and arrangement incidental to several specific applications thereof have been disclosed and discussed in detail, it is to be understood that the invention is limited neither to the mere detail or relative arrangement of parts, nor to its specific embodiments shown herein, but that extensive deviations from the illustrated forms or embodiments of the invention may be made, without departing from the principles thereof.

What I claim is: A container and closure therefor, the container being of generally cylindrical shape and having a' lower wall, an internal metallic ring positioned at the'upper end of the container, the container and the ring having a plurality of spaced, aligned apertures therein, the apertures in the ring being threaded, the closure comprising a metallic membe'r formed with an upwardly-extending annular flange closely fitting the upper, inner marginal edge of the ring, and a downwardly-depending annular flange closely fitting the upper, outer marginal edge of the container, such latter flange having bayonet slots therein aligned with the apertures in the container and ring, and headed screws positioned in such apertures to lock the closure in'clos'ing relation after such closure has been rotated to position such screws at the inner ends of the bayonet slots.
