Abstract

Improvements in the manufacture of stackable collapsible containers, especially those intended for the transport and storage of fruits and the like, characterized by the fact that they start from a sheet of semirigid material, such as corrugated cardboard, in which some blanks and lines are cut. longitudinal bends that result in the obtaining of a central portion and two other lateral ones that correspond, respectively, to the base and the larger sides of the container, the portions of which are extended, with sectioning of the said bending lines, to provide, in the central portion, double-walled sides and, in the lateral portions, reinforcing elements to be interposed between this double wall, these last elements being achieved by repeated bends of the corresponding portions until forming parallelepiped bodies which are arranged inside the double wall , each one in the opposite part in relation to the greater side from which it proceeds, in order to give n between the various component sides of the container, derived from these reinforcing elements, in the central part, upper flanges to offer prominences in order to obtain fitting arrangements for the coupling of the containers in stacking, whereby such prominences they coincide with slots made in the lower part of the container, for the penetration of those, existing in the central part of the portion destined to form the double wall, a window through which emerges the corresponding prominence, of whose window, of profile in T, a tongue is extracted such that it is applied, along its longitudinal section, around the same prominence, while its transverse section is tight, for its retention, inside the longitudinal opening of the window itself.
