The package shown in Figures 1 to 6 includes a cover 1 and a tray 2 that fixes the cover. including.

The cover is shown in Figure 1 made of cardboard or other suitable sheet material. Formed from blank. Said blank has side panels or flaps 11 along its length. including a rectangular central panel 10 extending from the sides, the side edges of said flap being centered It converges in the direction away from the panel. At least the central panel 10 usually has pictures. It may include a central portion on which the handle material is placed and which is transparent. Blanc Fold the flap 11 along the line 12 and make a crease to make it easier to pop. -Or transform it in other ways. Also, fold the short sides of the center panel in the same way. It has an adjacent end panel or flap 14 with a line 15. Said end flap 14 extend the fold line 12 through the extended end flap portions 16 on their sides. Extends beyond. The flap portions 16 converge away from the central panel 10. It is separated from the flap 14 by a fold line 17.

Parallel perforations 20 or other lines of weakness extend from one end flap 14 at right angles to the flap. It extends from a small notch in the edge of the wrap, said notch being such that the cover 1 2. After assembly, pull the cover upwards to reveal the contents of the tray. A tab portion is defined between the cutouts. one or more of the aforementioned The line of weakness may be continued to the opposite free edge.

The tray 2 is molded of plastic material and has a bottom 25 and side and end walls 26. and the side walls and end walls converge slightly outwardly and upwardly from the bottom to form the basin. This makes it easier to release the tray from the mold it is in. As you can see from the plan, tray 2 has a surface of 29. It has rounded corners 27. Hollow reinforcing ribs 30 are formed on each side. and extends downward to the bottom 25. The free edge of the wall 26 has an outwardly bent edge 31. It is formed as follows.

The cover 1 is assembled with the tray 2 by folding the four flaps 11 and 14 downward. erected, each end flap portion 16 has a fold line 17 at the side edge of the flap 11. They are secured together under the adjacent side flaps 11 with a suitable adhesive. yes The assembled structure then becomes an inverted top release box with its flaps truncated. Forming pyramidal shaped side walls that converge inwardly towards each other.

To assemble cover 1 and tray 2 to complete the package, use a flat and patterned As shown in FIG. 6A, the cover in the form of a blank printed with It is sent from the stack 35 and placed on top of the tray filled with contents. opening of the tray The apex is sealed with a thin transparent plastic film if necessary.

The position at this point is as shown in the bottom view of Figure 4, and the edge 31 of the tray is bent. It lies within the rectangle defined by lines 12 and 15. Next, apply an appropriate amount of suitable adhesive. is applied to the upper surface of the flap end portion 16, as indicated by arrow 40 in FIG. 6B. Pressure is applied by an assembly tool, and the pressure applied in the direction of arrow 41 also causes the flap to These flap portions move downwardly onto the flap 14 as the flap is folded downwardly. Fold minute 16 downward. The free edge of the flap 14 slightly does not reach the floor 25 in position, the end flap portion 16 extends at an angle less than or equal to a right angle to an adjacent flap. and engages the wall 26 of the tray.

During the next step of the assembly process shown in Figure 6C, the end flaps 14 are held in place. Then, the side flaps are also bent downward by an assembly tool acting in the direction of arrow 42. It will be done. The lateral ends of the flaps 11 engage the adhesive surface of the end flap portions 16 and finally position them.

The flaps 11 and 14 are in these positions until the adhesive is sufficient to secure them. The assembly tool is then removed to complete the assembly.
