The invention consists of a convertible briefcase which can be used in two different models, each of a different size and capacity. Its technical field is thus that of purses, handbags, and briefcases, with the feature that it does not require ancillary or mechanical resources of any type for the transformation. The invention is characterised by being made up of a container whose internal bottom half constitutes a closed recipient of parallelepiped section, formed on the basis of four walls of parallel pairs, two of which are narrower than the other two and joined by a bottom rib to a flat base. The interior recipient is provided with an upper closure base, opened in two halves, which can be closed by means of a zip. The upper half of the container is made up by the prolongation of the four walls which basically form the interior recipient, with the special feature that those of smaller width, when extended, form a section to cover and close the unit, and these may be joined up by means of a zip closure so as to convert the unit to one of larger size. This unit can be folded along the lines defining the internal recipient conforming the the smaller unit. The two closing bases of both recipients contain an external system of rings which allow for the adaptation of any fixing device. Figures 1 and 2 of the drawings show, in turn, the smaller and larger capacity models of the briefcase. Figure 5 is a cross-section through one of the sides in figure 2, while figure 4 shows a practical example of the phase of conversion.
