The closing together of the side wall sections to the form illustrated in FIGURES 3 and 4 is then completed, and the tabs 8), 81 and 82 on the end wall 30 are inserted into the slots '78, '79 and 80.

The bank or hollow body is thus set up to the form illustrated in FIGURES 3 and 4. The-end wall 11 is shown as having a slot or opening 120 through which coins, etc., may be inserted into the interior of the hollow body. When the bank is filled, or its contents ready for deposit, it may be taken to the bank for deposit of the contents, and a new bank or hollow body may be furnished.

In FIGURE 3 the wing sections 2f), 21 and 25, 26 are illustrated in downwardly inclined positions substantially coextensive with the upper side wall section, and extend downwardly therefrom. The wing sections are illustrated of generally triangular form and thus present downwardly directed pointed ends, but this may vary within the scope of the present invention.

In FIGURE 4, the wing sections 2t), 21 and 25, 26 are illustrated in upwardly inclined positions substantially 2o-extensive with the lower side wall sections 12 and 16, and extending upwardly thereabove.

The wing sections 20, 21 and 25, 26 are swingable to the positions illustrated in FIGURES 3 and 4 about the fold lines 23, 24 and 28, 29.

The. outer surfaces of the side wall sections 12, 13 and 16, 17 are preferably ornamented, for example, by printed matter 121 thereon` The outer surfaces of the end walls 11 and 30 and the outer surfaces of the top and bottom wall sections are preferably ornamented as shown at 122. The outer surfaces of the wing sections 20, 21 and 25, 26 are also preferably ornamented as shown at 124 and 125. The ornamentations on the outer surfaces of the wing sections 20 and 25 are preferably different from the ornamentations on the outer surfaces of the wing sections 21 and 26, or differently colored, to provide different appearances, depending upon whether the wing sections are turned downwardly, as illustrated in FIGURE 3, or upwardly, as illustrated in FIGURE 4. This provides a novelty and interest for the child.

When the structure is set up as illustrated in FIGURES 3 and 4, the wing sections are two-ply and of a character to make the structure rigid and sturdy. And the manner in which the sections are interlocked is effective to secure or lock the sections together and to provide a sturdy and rigid structure.

It is to be understood that the ornamentations illustrated in FIGURES 3 and 4 are merely illustrative and may vary widely within the scope of the present invention. Moreover, it will be understood that a great variety of figures and shapes ornamented as desired may be Pm duced by only slight changes in the lines of fold and the shapes of the various portions of the blank, with variations in ornamentations as suitable or desired.

Therefore, the embodiment of the invention disclosed in the drawings and the specification is for illustrative purposes only, and it is to be expressly understood that said drawings and the specification are not to be construed as a definition of the limits or scope of the invention, reference being had to the appended claims for that purpose.
