Figure 7 is a side sectional view of the lower section of a jug of a blender or similar apparatus, having the support system of the invention in a modified alternative, together with the detailed enlarged view D, which allows better observation of the mentioned modification.

Detailed description of the invention Figure 1 shows a side section view of a jug (0) of a blender or similar device, which has a mounting (2) of sheet support (L) installed. It is possible to observe a jug (C) belonging to the blender or similar device, comprised of a catch (8) for the limitation of the run and a dividing element (9), which is fixed to the motor shaft of the mentioned apparatus and it is the first to be coupled to the coupling element (M) whose axis rotates inside the internal bearing (not shown) of the mentioned assembly (2) fixed to the leaves (L) to rotate them. Accordingly, the divider element (9) and the coupling element (M) form an elastic coupling sleeve between the motor shaft and the shaft (2) of the blade support assembly (L). They also have a notch (4) in the aforementioned assembly (2), which houses a latch (7 ') in a band of flexible material (11) diametrically surrounding a round part (15) which comprises the assembly (2) . The jug (0) has around its internal section a surrounding protrusion (14) which makes contact with a sealing ring (12) of deformable material, which applies pressure at all times when the assembly (2) is installed in the pitcher (0), thus providing an efficient seal. The mentioned band also has two curved bending spring portions (6), not shown in this Figure, integrated to a length of the rectilinear band (10) fixed to a button (3); near the portions (6) of the spring, projecting from the length (10), there are two arms of clips (1) of a laminar shape showing a latch (7) at one of its ends. The jug (0) has, on the side of its body, near its base, a through opening in which the button (3) is fixed, which can be depressed by the user, moving it through the aforementioned opening, without However, without the challenge of the jar (0). Obviously, this button (3) is projected towards the external side of the aforementioned jar (0), for user access. Figure 2 shows a side view of the support assembly (2) outside the jar (0), comprised of the round part (15) which is hollow, truncated cone-shaped in its upper section, forming an open cavity in its lower section wherein the coupling element (M) will be located, not shown; there is also a detailed notch (4) parallel to a notch (5), both around the intermediate portion of the part (15). The notch (4) will accommodate the latches (7) and (7"), when the assembly (2) is installed in the jar (0), while the notch (5), which has all around its bottom edge a surrounding wall (13), is proposed to house the sealing ring (12). Figure 3 shows a top view of the inner lower section of the jug of a blender or similar apparatus, showing the mentioned assembly (2) installed in the jug (0), represented by a dotted line, and with the leaves (L) ), the sealing ring (12), the notch (5) and the surrounding wall (13) that have been omitted to give a clearer view. Notice how the latches (7) and (7 ') fit or fit into the aforementioned notch (4), firmly holding the assembly (2) in place. The portions (6) of the spring of the band (11) are interconnected with each other, as explained above, by a length (10) of the rectilinear band, which is integrated to them, fastened to the button (3) and the arms of the clamps (1). Figure 4 shows what happens when the user presses the button (3) to remove the support assembly (2) from the sheet from the jug (0). The leaves (L), the sealing ring (12), the notch (5) and the surrounding wall (13) were omitted to offer a clearer view. The button (3) pushes the rectilinear length (10) of the band, which in turn pushes the spring portions (6) and will lean on the inner wall of the jar (0) and, since they are integrated with the band (11), will cause it to open, which causes the movement of the sear or bolt (7 ') coming out of the notch (4) of the assembly (2). At the same time, the intermediate section of the arms (1) of the clamps, are also pressed against the assembly (2) that makes them open, also moving their latches (7) out of the notch (4). Figure 5 ends by showing the situation of the maximum pressure on the button (3), when the clamps (1) and the band or strap (11) have already fully opened and the latches (7) and (7 ') they are already completely out of the notch (4), thus releasing the assembly (2) and allowing its quiet removal from below the jug (0). The leaves (L), the sealing ring (12), the notch (5) and the surrounding wall (13) were omitted to offer a clearer view. Figure 6 is a side view of a support assembly (2 ') separate from a jug (0) of a blender or similar apparatus, not shown, which constitutes an alternative modification of the invention. Leaves (L) were omitted only because of a larger graphic simplicity. This assembly. { 2 '), is almost completely identical to the support assembly (2) already described, which is formed by the same round hollow part (15), which also has the notch (4) mentioned, parallel to a notch (5') , which surround both the middle section of part (15). The notch (5 '), proposed to house the sealing ring (12'), not shown, has its entire surrounding lower edge wedged and does not have the surrounding wall (13) mentioned, this being the only difference between the support mounts ( 2) and (2 '). Figure 7, a side sectional view of the jug (0), has the support assembly (2 ') installed and constitutes an alternative modification of the invention. It is possible to observe the body (C) belonging to the blender or similar device, already described. The jug (0 ') has around it a surrounding projection (14'), this projection (14 ') has everything around its lower edge in the shape of a wedged edge (17). This edge (17) makes contact with a wedged edge (16) of a sealing ring (12 ') made of a deformable material, pressing it in all. While the assembly (2 ') is installed in the jar (0'), thus providing an alternative form of sealing, this variation is equally efficient. The detailed view D, indicated in a circle of dotted lines, shows an enlarged cut of the wedged edge (16) of the sealing ring (12 '), noting that it is located adjacent to the outer side and the upper sections of the ring (12'). ). This view also provides a better picture of the contact area between this edge (16) and the wedged edge (17) of the surrounding projection (14 '), as well as the notch (5') in which the sealing ring (12) ') is hosted. Now it is possible to understand the function of the run stop limiter (8) in the body (C), with the assembly (2, 2 ') installed, even if you try to push the said button (3), the rectilinear length ( 10) of the band will make contact with the retainer (8) without allowing the button to move, thus preventing the release or removal of the mentioned assembly (2, 2 '). The jug (0, 0 ') must be removed from the body (C) of the apparatus so that it is capable of removing the mentioned assembly (2, 2'). To insert the assembly (2, 2 ') into the jar (0, 0 ') it is sufficient to introduce it through the opening in the bottom of the jar (0, 0') and push it into place. Thanks to the truncated cone shape of the part (15), the assembly (2, 2 ') is introduced to the jar (0, 0') and stops when the surrounding projection (14, 14 ') touches the sealing ring (12, 12') and, simultaneously, the detents or latches (7) and (7 ') are inserted into the notch (4) strongly securing the assembly (2, 2'). The following advantages can be obtained with the system proposed here, either that originally described according to Figures 1 to 5 or its variable described in Figures 6 and 7: the jug (0, 0 ') without the blade assembly (2, 2 '), can be washed better and easier in dishwashing machines; the system of equipment or adjustment of the assembly (2, 2 ') to the jar (0, 0') is very reliable to keep the leaves in their correct position, even when it is operated with foods that are difficult to be shredded, such like seeds, ice cubes, etc .; low cost Having described a preferred embodiment, it should be understood that the scope of the present invention covers other possible variations, being limited only by the content of the appended claims, wherein possible equivalents are included.

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.
