The tongues 5 or fingers 5 are of approximately the same thick ness as the infolded ply 2 (Fig. 3) and terminate adjacent to the edge of said ply 2. A strip 6 is attached to the inner surfaces of the tongues or ñngers 5 entirely around the inside of the box 10 and covers said tongues or fingers and consti The lid of the box may also be formed in a similar manner so that the side wall of the lid tutes an additional reinforcement and ornament will telescope about the side wall of the lower portion of the box or carton.

The strip 6 has one edge seated against the Wall 4 and the opposite edge ap proximately in alinement with the edge of the 15 apparent from the following description, refer ence being made to the annexed drawing, in which Fig. l is a plan view showing the inner side of 20 the outer wall before the same is folded or shaped infolded ply 2. Fig. 3 is a perspective View in section and with parts broken away of a portion of the box or An alternative construction is shown in Figs. 4 and 6. As there shown, a wall I’ is attached to the tongues or fingers 5 and has its edge in aline ment with the exposed surface of the wall 4. In stead of forming an inturned ply 2 integral with the wall I', a separate strip 'I is attached to the inner surfaces of the tongues or fingers 5 and to the inner surface of the wall I' beyond the tongues or ñngers 5, said strip extending the full Width of the wall I’ and having its exposed edge in alinement with the exposed edge of said carton. strip I’. for attachment to the top or bottom wall of the box or carton. Fig. 2 is a plan view of a wall constructed for use to form the bottom wall or the top Wall of the box or carton. Fig. 4 is a perspective view in section and a 30 part broken away showing another portion of the box or carton. Fig. 5 is a vertical cross-sectional view of a complete box or carton made in accordance with this invention. ,5 Fig. 6 is an enlarged sectional View showing a portion of the lid and a portion of the lower part of the box or carton.
