Arrangements are provided for an automatic vending machine, including a vertical support frame, a top plate mounted securely on the top end of the support frame, and a bottom plate mounted securely on the bottom end of the support frame. An L-cross-sectioned side plate is hinged to a side wall of the support frame. A rib arrangement is provided on the side plate and includes an L-shaped first horizontal rib, an L-shaped second horizontal rib, an L-shaped third horizontal rib, an L-shaped fourth horizontal rib and a vertical rib. The first horizontal rib is positioned just over the top plate. The second horizontal rib is positioned just under the top plate. The entire length of the second horizontal rib extends under an intermediate portion of the first horizontal rib, so as to conceal an L-shaped peripheral plate portion of the top plate between the first and second horizontal ribs. The third horizontal rib is positioned just under the bottom plate. The fourth horizontal rib is positioned just over the bottom plate. The entire length of the fourth horizontal rib extends over an intermediate portion of the third horizontal rib, so as to conceal an L-shaped peripheral plate portion of the bottom plate between the third and fourth horizontal ribs. The vertical rib connects an end of the second horizontal rib to an end of the fourth horizontal rib.
