1 Claim. (Cl. 220-76) This invention relates to metallic shipping conre-assembly. Goods which it is desired to intainers or cans", and it is among the objects'of sure against bootlegging re-fllling are accordthe invention to provide a container which can ingly also particularly well safeguarded; In the be sealed quickly and simply without necessity embodiment of the invention in Fig. 1, the conof resort to soldering or mechanical crimping, tainer body 2 has a suitable bottom closure'3 per- I and which can not be unauthorizedly opened manently secured, as by seaming, etc., and after without destroying. the goods have been filled in, the cover 4 is Other objects and advantages will appear as snapped into place by the inter-locking indentathe description proceeds. tions 5, B. The container body is provided with To the accomplishment of the foregoing and a raised be'ad beyond the edge 8 of the cover. 10 related ends, the invention, then, comprises the Such bead may extend transversely more or less features hereinafter fully described, and parcompletely about the container, as convenient. ticularly pointed out in the claim, the following In the case of containers of square section as description and the annexed drawing setting forth' indicated in Fig. 2 in detail, the bead may exin detail certain illustrative embodiments of the tend across the greater expanse of each side, and 15 invention, these being indicative however, of but in the case of a container of circular section, as a few of the various ways in which the principle of indicated in Fig. 4 it may completely encircle the the invention may be employed. circumference if desired.

Instead of having a rounded been such as to permit opening thus as easily or smoothly curved contour as in the preceding as closing.

I therefore particularly point out and distinctly claim as my invention:

A device of the character described comprising a container body, a cover therefor and means for preventing intact removal 'of said cover, said means including a reinforcing bead on said container body to prevent bending therof, said head lying beyond and adjacent said cover when it is in place; a central depression in said cover; a narrow groove in said cover for tightly receiving the upper edge of said container body; and a plurality of spaced interlocking indentations on said container body and cover.
