Abstract: 671,650. Wages envelopes. SMITH, J., and GATES, W. H. July 23, 1949 [May 7, 1949], No. 12254/49. Class 146 (ii). A wages envelope, adapted when sealed to permit counting of currency notes and cash therein, but preventing removal of the notes except by damaging the envelope, comprises a body portion of a width to accommodate the notes widthwise having the edge 1 less than, and the edge 2 approximately equal to the length of the notes 6, a main flap 4 extending beyond the longer edge 2 and an auxiliary flap 8, extending from a point on the edge 2, preferably defined by a hole 11 or other suitable marking, at the same height as the edge 1, and passing across the main flap. The auxiliary flap 8 is first folded over together with the adjacent corners of the notes 6 and secured by a portion of the adhesive area 15 (preferably of the self-adhesive type) together with an adhesive area 14 if desired. The main flap 4 is then folded over together with the notes along a horizontal line and secured by adhesive, the main flap having a cut away part 5 so that when sealed the corners of the notes are exposed for counting. The body of the envelope has openings or a transparent window to allow the coins to be counted. Specification 383,748 is referred to in the Provisional Specification.

Abstract: 1,248,111. Packages. J. MACMANUS. 18 Feb., 1970 [7 March, 1969], No.12265/69. Heading B8C. A flanged pie dish 8 is held against the bottom wall of a containing sleeve by tabs 14 to prevent the pie crust 10 contacting the top wall of the sleeve. The tabs 14 are pressed from the side walls of the sleeve and engage the top of the dish flange. Tabs 17 pressed from the top wall of the sleeve engage the edge of the flange to prevent the dish slipping from the sleeve. The action of the tabs 14 and 17 is reinforced by tabs 15 pressed from the side walls of the sleeve and havslots 16 which engage the dish flange. In a modification, Figs. 5 and 6 (not shown), the dish is prevented from slipping by two elastic bands which engage diagonally opposite pairs of slots cut into the sleeve side walls and extending into the top and bottom walls. The crossed cords also serve as a handle for carrying the container. In another modification (not shown) the sleeve has end closure flaps to prevent slipping of the dish. Plastics posts may extend through the pie from the bottom crust of the pie to engage the top wall of the sleeve, Fig. 7 (not shown). The sleeve may be made of silicon coated cardboard or may be a plastics extrusion.
