'- SHIPPING- CAN.

:Application filed February 24-, 1925- To. will whom it 72mg concern Be it knownwthat (I, Jam-ms M..GouenLrN, a citizen of the United states residing at 19 N. Do-rnance St, Kingston,=, in the. county of Luzerneamt-State of Pennsylvania, haveinvented ainew and-useful Shi-ppingfian, of whi-eh the following I is a specification.

;This invention relatestoshipping eontai ners of; the metal; drum: type and more particularly toaa closure for use in Connection therewith, oneof the obj ects;-bein=g to provide a closure-which acts as a positiveseal so ;as--; to 'P'l'QVeimtpowdered contents ofthe container from sifting therefrom.

Another object is to provide a closure which, when-subjected;to;the weight of. the contents of the .conta-iner, will ynot work looseb-ut, onthe eontrary, will .act to more tightly .8631 the. container.-

A still further object is to provide a clos-' ure which can be applied readily and will maintain :the container :sealed in spite of any rough usage to which it may be subjected.

It is the practice to ship poisons in powdered form in metal drums but great care must be exercised to prevent any of the powder from sifting out of the containers. Otherwise poison lost in this Way is likely to be left in cars subsequently used for transporting stock food with the resultant loss of live stock due to consumption of poisoned food. Consequently government requirements are very severe and it is necessary to use containers from which powder cannot sift under any circumstances arising during the transportation and handling of containers. It is an object of the present invention to provide a container and closure meeting all of the tests required without unduly complicating the device.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the coinbination and arrangement of parts and in the details of construction hereinafter de scribed claimed, it being understood that-changes in the precise embodiment of the inventibn herein disclosed maybe made within tliejfscope of what is claimed; without departing from the spirit of the-invention.

:In theiaccoinpanying drawings the prefer-reddiorm of. the invention has been shoavn.

In aid drawings l igure 1 isa plan viewuofa container ShQW'i'llQ the closure fastened in :place.

Fig. 2 is ,a section-on l'i ne,2 -2 of Fig. 1.

:Fig'. is a plan. view ofthe; container, the closure being shown partly inserted.

A; is an eljil-arged section through the interlitting portions of the container and closure.

FFig. i5 is a detail view of one of the l-randles,i its attaching strap-being shown in section.

.Relierringtothe figures by characters of reference 1 designates a metal container or drum preferably cylindrical shown and provided with aihead Zset inwardlyfrom theend. of the. drumand connected tothe drunr in; the usual or anyi preferred manner. Thisfl ead has a central circular opening 3 f om he W al i -Which ex end an; ward y projecting circular flange 4:. This flange constitutes a portion of the sealing means and also holds the head against buckling.

The closure includes a metal disk 5 having an annular flange 6 the free edge of which is turned laterally and upwardly as indicated at 7 to provide an annular channel 8. The external diameter of flange 6 is approximately the same as the internal diameter of flange 4.

Pivotally mounted on the disk 5 near its periphery are buttons 9 adapted, when in one position, to lie Wholly Within the circumference of the disk. When the disk is in position in opening 3, however, these buttons can be turned so as to lap head 2 as shown in Fig. 1.

Secured to the disk 5 at diametrically opposed points are straps 10 each having a central transverse arched portion 11 struck therefrom and outstanding from the disk. Projecting into engagement With each of these arched portions are the terminals 12 of loops 13 constituting handles. Said terminals are normally out of alinement as shown particularly in Figure 5 and, as they are held to the disk 5 by the arched portions, the loops 13 will also be held normally against the disk. By swinging the loop away from normal position the terminals 12 will be sprung or forced into alinement, as will be obvious. After the loop has been used as a handle for lifting the closure, it can be swung back against the disk 5 where it will be held until again swung forcibly away from the disk.

After the container has been filled to a point below the flange 4, it can be closed and sealed by inserting the closure edge first downwardly through the opening 3. The closure is capable of slightly buckling to permit this insertion and thereafter said closure is swung to a substantially horizontal position and pulled upwardly bymeans of handles 18. It might be stated that channel 8 has a soft rubber filling or a filling of anyother suitable sealing material indicated generally at 14. Thus when the closure is forced upwardly its flange 6 will frictionally engage and bind tightly upon the inner surfaceof flange 4 while the inner edge of flange 4 will ultimately become seated in channel 7 and embedded in the sealing material 14:. The parts are so nicely proportioned that the closure will be held in place securely by friction only but as a further guarantee against accidental opening of the container the buttons 9 are provided and can be turned into engagement with the head 2.

It will be obvious that the head is reinforced by the container and it is impossible for any pressure exerted from within the container to force the closure from position. This closure and container have withstood all the requirements of government tests By mounting the handles as described they will not swing downwardly to hanging positions and thus tend to drive the closure inwardly should the container be dropped while in an inverted position.

lVhat is claimed is The combination with a container having a head opening and a continuous flange extending inwardly from the edge of the opening, of a closure insertible edgewise through the opening and including an annular flange of substantially the same diameter as the opening for frictional engagement with the inner surface of the head flange, an annular channel upon the closure flange, and elastic sealing material in the channel for the reception of the free edge portion of the head flange, a handle upon the closure, and means movably mounted on the closure for engaging the head.

In testimony that I claim the foregoing as my own, I have hereto aflixed mysignature.
