DEFORMABLE CONTAINER FOR INJECTING MEDICAL OR COSMETIC SUBSTANCES DESCRIPTION OF THE INVENTION The present invention relates to a deformable container for injecting medicinal or cosmetic substances, that is, a container for dispersing a dose of medicinal or cosmetic substance, in the form of a liquid or a foam, and injecting it into a cavity. of the human body, for example, in the anal cavity, the nose or the ears. The state of the art includes the Italian patent for utility model No. 213,228 by the same applicant, which relates to bellows dispensers for medicinal substances for microenemas, with a built-in cannula, which includes bellows with a cylindrical body equipped with a cannula whose axis is aligned with the axis of the bellows. The bellows of the dispenser are more than uncomfortable to use, since they force the user to rotate his wrist to compress or squeeze the body of the bellows; furthermore, it is impossible to completely empty the body, since the reduction in the axial length of the bellows when compressed is limited by the pleats of the bellows that are closed or together. REF: 25208 The incomplete discharge of the body of the bellows makes it impossible to use all the substance contained in the dispenser. The state of the art also includes deformable containers, with drip nozzle or atomizer, for introducing liquids in the nasal cavity or in the ears; the containers also have the defect that they are difficult to empty completely, due to the limited deformability of the container. The present invention aims to solve the technical problem of finding a deformable container for injecting medicinal or cosmetic substances, in the form of a liquid or a foam, into the cavities of the human body, which can be emptied almost completely, reducing to a minimum the amount of substance contained in this that can not be used and that does not force the user to perform unnatural rotations of the wrist when using the container. The present invention solves such a technical problem by adopting a deformable container having a body in the form of bellows and a dispensing cannula, characterized in that the axis of the bellows and the axis of the cannula are substantially perpendicular to each other, the section of the bellows has dimensions that increase progressively, from the extremities to the center of the bellows. The advantages offered by the invention are: its easier and more comfortable use, particularly when the container is used for microenemas; the container can be emptied almost completely, thereby reducing to a minimum the amount of substance that is not used; simplicity and low production costs. Some embodiments of the invention are illustrated, simply by way of example, in the two tables of annexed drawings, in which Figure 1 is a perspective view of a first version of the container described; Figure 2 is a view like that of Figure 1, with the protective cap removed; Figure 3 is an exploded view, partially cut away from the container of Figure 1; Figure 3A is a partial longitudinal section of the container of Figure 1, assembled; Figure 4 is a side view of the container of Figure 1 during use; Figure 5 is a view like that of Figure 1, which relates to a second version of the container described with a cannula obturator; Figure 6 is a view like that of Figure 3 that relates to the container of Figure 5; Figure 7 is a view like that of Figure 3A, which relates to the container of Figure 5.

Figure 1 shows a container according to the invention, consisting of a body 2 in the form of bellows, with a neck 3, whose axis is perpendicular to the axis of the fuell. The body 2 of the bellows is made of a number of pairs of layers folded as in an accordion, with transverse dimensions that increase from the ends towards the bellows towards the center and with the intermediate layers being annular in shape. The contour of the layers can be polygonal or curved. The body 2 is therefore collapsible in a double truncated pyramid or cone with the width of the bases in the center. The neck 3 (Figure 3) has an outer ring 4, in an intermediate position, and a conical elongation in the neck opening 6. A dispenser or dispenser in the form of a cannula 7 is inserted in the opening ß of the neck 3, the dispenser or distributor has at its lower end a ring 8 that is supported on the edge of the neck 3, and a lower cylindrical extension 9 for its insertion in the opening 6 of the neck 3 to form a seal. A cover 11 is inserted over the cannula 7 and the neck 3, which consists of a hollow cylindrical base 12, whose internal diameter is smaller than the external diameter of the ring 4 to allow the lower edge of the base to be felt on it. Inside the cylindrical base there are: a seat 13 for the rapid insertion of the ring 8 of the cannula 7; a conical seat for the insertion in this of the conical elongation 5 of the neck 3 of the container 1 and an annular projection 15 which acts as a guide notch for the elongation 5. The upper part of the lid 11 ends in a removable plug 16 connected to the base 12 along a predetermined fracture line 16a. The plug 16 has an internal projection 17 for closing the dispensing opening 18 of the cannula 7. Figure 5 shows a second version 19 of the container as described, in which the cannula 7 and the lid 11 are replaced with an integrated lid 20 with a cannula 21 (figure 6). The base 22 of the lid 20 is hollow with, on its inner side, a conical seat 23 for elongation 5 of the neck 3 and an annular projection 24 which acts as a guide notch for the elongation 5. Within the lid 20 a projection substantially cylindrical 25 extends downward which is inserted and seals the neck 3. A removable closure seal 26 for the opening 27 of the cannula 21 is connected to the opening along a predetermined fracture line. The operation is as follows: once the plug or obturator 16, or the guarantee seal 26, has been removed, the cannula 7, or 21 is inserted into the body cavity in which the substance contained in the container 1, or 19, has been introduced, and the body 2 of the container is compressed in transverse direction with respect to the axis of the cannula, thus dispensing or distributing the substance contained in the body 2. It should be noted that with the layers of the body 2 of the fully compressed bellows, the configuration of the bellows layers, with dimensions decreasing outwards, allow a greater degree of compression and, consequently, an improved emptying of the body 2. In the case of the first version of the container, as in Figures 1 to 3A, it is possible to close the container by inserting the cap or obturator 16 into the cannula 7 in such a way that the internal projection 17 closes the opening 18 of the cannula: this allows one or more posterior installations of the container. In practice the materials, dimensions and execution details may be different but technically equivalent to those described without departing from the legal domain of the present invention.

It is noted that in relation to this date, the best method known by the applicant to carry out the aforementioned invention, is the conventional one for the manufacture of the objects to which it relates. Having described the invention as above, property is claimed as contained in the following:
