As thus clearly understood, the containers in unassembled condition are supplied at the point of ?lling, and are packed with the articles to be enclosed, whereupon the cover I‘ is pressed down into position, the inter-locking indentations 6, 5, 10 etc., snapping together, and the end edge of the container body seating into the cover-groove ill. The cover is thereby positioned to remain, until destroyed in opening. v Other modes of applying the principle of the invention may be employed, change being made as regards the details described, provided the fea tures stated in the following claim, or the equiva lent of such, be employed. I therefore particularly point out and dis tinctly 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 con tainer body to prevent bending therof, said head lying beyond and adjacent said cover when it is 10 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 15 said container body and cover. ~ GEORGE M.
