To make the retainer from the material shown in FIG. 2, the inner surfaces of the handle plates 27 and 28 and the reinforcing plates 29 and 30 are first coated with dots as shown in FIG. 2.
Adhesive is applied and then reinforcing plates 29 and 30
are lifted and bent to the right along fold lines 31 and 32, respectively, and the handle plates 27, 28
is placed in a position where it makes surface contact with the inner surface of the

Next, the horizontal partition plates 54 and 55 are attached to the fixing pieces 6.
2 and 65 from the surface of the material downward (toward the back side of the drawing in FIG. 2), and then bent 180 degrees to the left and placed in the position shown in FIG. 3. Adhesive is then applied to the transverse bulkhead plates 44 and 45, as shown in stippling in FIG. Almost simultaneously with the bending of the transverse bulkhead plates 54 and 55, the transverse bulkhead plates 56 and 57 and the fixing pieces 68 and 71 attached thereto are lifted along the fold lines 60 and 61 and then moved 180 degrees to the right. The inner surfaces of the partition plates 56 and 57 are bonded to the inner surfaces of the partition plates 44 and 45, respectively. The shape of the cage at this time is as shown in FIG.

Following the above operation, adhesive is applied to the fixing pieces 68, 71, handle plates 27, 28, and intermediate plates 9, 19 as shown in dots in FIG. After the transverse bulkhead structure located at is lifted together with the intermediate partition structure consisting of the intermediate plates 9, 19 and the intermediate partition plate 40, the fold line 1
1 and 20, so that the fixing pieces 68 and 71 are bent to the left along lines 1 and 20, respectively, as shown in FIG.
It is glued to the inner surfaces of side walls 12 and 1. moreover,
In Figure 3, the transverse bulkhead structures on the left side of the material are shown at fold line 4 along with the fixing pieces attached to them.
6, 47, 48, and 49 to the right and placed in the position shown in FIG. The intermediate wall plate 40 is then lifted and bent downward along the fold line 41 and placed in the position shown in FIG.

Next, the intermediate plates 8, 17 and the fixing pieces 62, 6
5, adhesive is applied as shown in stippling in FIG.
After the intermediate wall plate 38, the sub-bottom plate 24, and the transverse bulkhead structure on the left side of the material in FIG. 5 are lifted, they are bent to the right along fold lines 5, 15, and 25, as shown in FIG. placed in position. By this operation, the fixing pieces 62 and 65 are adhered to the inner surfaces of the side walls 1 and 12, respectively. Furthermore, in the secondary piece 33,
Adhesive is applied as shown in stippling in FIG. 6, and then this sub-piece 33 is bent along the fold line 32 and adhered to a part of the surface of the intermediate plate 17. Then, after the intermediate wall plate 38 is lifted, the fold line 39
7 and placed in the position shown in FIG.

In order to complete the cage, adhesive is further applied to the intermediate plates 8, 9, 17, 19, the reinforcing plates 29, 30, the sub-piece 33 and the adhesive piece 2, as shown in dots in FIG. Next, the bottom plate 21 and the sub-bottom plate 24 are bent along the fold lines 23 and 26, respectively (folded into two vertically). Next, the part of the material above the fold line F in Figure 7 is lifted and bent downward, and placed in the position shown in Figure 8, thus completing the cage in the crushed state. be done.

In order to change the cage from the collapsed state shown in FIG. 8 to the state shown in FIG. It is sufficient to apply a leftward force to the intermediate ends of the end wall plates 6 and 14 while restraining the end wall plates 6 and 14. This inflates the retainer and separates the side walls, and at the same time, the bottom plate 21 and the sub-bottom plate 24 return to the planar shape. The retainer is then folded back to the locking notches 8a, 17.
The state shown in FIG. 1 is maintained by the engagement of part a with one end of the bottom plate 21.

(Effects of the Invention) Thus, a product holder according to the invention is provided which has a reinforced bottom wall structure with a double plate structure, which structure provides the required additional strength and retains the product. The tendency for vessel breakage, particularly along fold lines 3 and 22, is reduced. Furthermore, the sub-bottom plate 24 is wider than the bottom plate 21, and
Since the sub-bottom plate 24 is placed on the top surface of 21, the sub-bottom plate 24 and the adhesive strip 2 are bonded together on the untreated side (side) of the cardboard material, thereby causing the adhesive to penetrate into the cardboard material. Sufficient permeation is allowed, and therefore the adhesive strength between the sub-bottom plate 24 and the adhesive piece 2 is strengthened.

As shown in Figure 9, materials can be "interleaved" with adjacent materials to save on materials, and in a typical interleaving method, the bottom walls of two adjacent materials are The parts are placed abutting each other, and corresponding parts of both materials are placed offset relative to each other. Thus, there is material along one edge of each material that must eventually be discarded (ie, a strip of unused material). In the present invention, the irregular shape of the bottom wall allows the bottom wall of one material to be interleaved with the bottom wall of an adjacent material, and in this state, the basic structure of the cage is The target parts are longitudinally collinear, as shown in FIG. Therefore, in the present invention, the maximum amount of cardboard material can be effectively used without creating the amount of waste material that would normally be the case.

Thus, the present invention provides a double-plate bottom wall that has double-thickness intermediate and transverse bulkheads at all points in contact with the product and is less prone to breakage even at points where large stresses are applied. A product holder is provided herein.
