SEALED PACKAGE.-

APPLICATION FILED FEB. 10. I913- Patented Oct. 26, 1915.

FRANK PAYNE, OF ST. LOUIS, MISSOURI, ASSIGNOR- TO AMERICAN CAN COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY.

SEALED PACKAGE.

Specification of Letters Patent.

Patented Oct. 276, 1915..

Application fi1ed February 10, 1913. Serial No. 747,272.

To all whom it may concern:

Be it known that I, FRANK PAYNE, a citizen of the United States, residing in St. Louis, in the State of Missouri, have invented a new and useful Improvement in Sealed Packages, of which the following is a specification.

This invention relates to improvements in wide mouthed sheet metal sealed package and'it consists in the novel devices, parts and combinations of devices and parts, hereinafter described and made the subject matter of claim.

In the accompanying drawing which forms a part of this specification, Figure 1 is a plan view of a wide mouthed sealed Vessel, its removable cap being shown in section. Fig. 2 is a vertical section of the upper portion of a wide mouthed sheet metal sealed vessel with the cap removed, the seal being shown, as applied, but not secured. Fig. 3 is a sectional view similar to Fig. 2 showing the seal plate after the same is swaged or sealed. Fig. l is a View of the removable screw cap.

Certain kinds of trade, as for example merchants who deal in freshly roasted coffee,

require a reasonably air-tight package with a wide mouth, nearly or quite the diameter of the package in extent, to enable them to handle the roasted coffee easily. It is extremely desirable that there should be some method of not only closing but also of sealing this package, and various contrivances for securing the cap in place so that its removal and the consequent opening of the can will require the breaking of a seal of some sort, have been suggested and attempted. In the present invention no attempt is made to secure the removable screw cap to the wide mouthed opening, but instead a supplemental flanged countersunk sealing cap made of thin ductile metal, as taggers tin, is applied and secured by being swaged with a bead while thus in place so that it cannot be removed without cutting or disfigurement. This supplemental sealing cap is to be applied and sealed by the merchant after the can is filled, and may be readily and easily removed and thrown away by the user. It insures, by a cheap and simple device, the contents of the can from being tampered with while in transit, and at the same time enables the use of the common easily manipulated wide mouthed screw cap cover opening.

In the accompanying drawing, A represents the ordinary sheet metal coffee can.

B is the breast or top double seamed thereto. g

C 'is the neck of the wide mouthed opening, the upper edge of which is bent inward and downward forming an internal shoulder 0. This internal shouldered neck is provided exteriorly with the usual screw thread or bayonet catch projections D, and the cover E, see Fig. 4, provided with corresoonding screw thread or bayonet recesses D After the can. is filled with coffee the shallow cup-shaped sealing-plate F made with the walls f and the flange f is slipped into the mouth of the wide opening and forced down until the flange f encounters the upper edge of the neck, after which, in order to prevent the removal of this sealing plate, it is swaged in place, which may be done by applying a blunt tool, as indicated in dotted lines in Fig. 3, to form an external bead G which may extend all around or sufficiently to-lock the soft metal plate in position. After this the cap may be applied in the ordinary way.

I claim I In a sheet metal sealed container, in combinationz-a can body; a top permanently secured thereto, the top beingformed with an upwardly extending neck consisting of an outer wall having means for engaging the inclosing flange of a cover, an inwardly extending annular top and a short inner wall depending from the inner edge of said annular top. the lower edge of said depending wall forming a shoulder; a cup-shaped sealing plate of thin ductile metal fitted tightly within said depending wall, having a top flange extending over said annular top of the neck and having its vertical wall swaged outward against said depending wall and the lower portion of its vertical wall under the said shoulder of the depending wall; and a removable and replaceable cover having a securing flange which incloses said neck and engages the outer wall of the same.

FRANK PAYNE.
