DETAILED DESCRIPTION OF A PREFERENTIAL FORM OF EMBODIMENT

With reference to FIG. 1, a container 10 according to the present invention is installed in a dispensing machine 11 for a fluid product, of a known type and shown only partly in FIGS. 3, 4 and 5. The dispensing machine 11 comprises (FIG. 3) a plurality of pairs of fixed delivery stations 18, each having a substantially vertical axis of delivery “X1”.

The axes of delivery “X1” of each pair of delivery stations 18 are positioned at a determinate distance “D1” with respect to each other, according to a pre-defined lay-out.

In one form of embodiment, a suction pump 17, for example of the bellows type, is associated with each fixed delivery station 18, and is connected axially to the container 10 along the axis of delivery “X1”.

In this embodiment, the use of two suction pumps 17 substantially allows to double the rate of delivery, making the dispensing machine 11 more productive.

The container 10 according to the invention (FIGS. 1, 2 and 3) comprises, from the top to the bottom, a lid 12, a tank 13, and two outlet pipes 15 and 16, able to be connected coaxially with the respective suction pumps 17.

In the following description, simply as a non-restrictive example, the fluid product is indicated as a dye, but it is clear that the fluid product can be any other coloring liquid, such as for example a base for paint, an enamel, an ink or suchlike.

The lid 12 is shaped in a manner mating with the transverse section of the tank 13, and its only purpose is to selectively close the latter, in order to prevent the impurities and dust present in the air from depositing on the skin of the dye inside the tank 13.

In this case, the lid 12 is advantageously closed on the tank 13 in a seal-tight manner, in order to prevent the dye contained therein from drying out; the seal is achieved by inserting part of the lid 12 inside the tank 13. To be more exact, the tank 13 comprises at the upper part, on an outer wall 21, an insertion seating 19, while the lid 12 comprises on the lower part a perimeter abutment rib 20, able to rest on the upper edge of the outer wall 21, thus defining a position of reciprocal closure between the lid 12 and the tank 13 (FIG. 3). Packings, such as O-rings or suchlike (not shown here) are also advantageously provided, able to ensure the air-tight seal of the closure. According to a variant, not shown in the drawings, attachment members may be provided, of the snap-in type, through interference or coupling in shape, or other known type, suitable to ensure the air-tight seal of the lid 12 and the tank 13.

The tank 13 comprises, as we said, an outer wall 21 shaped so as to define an inner compartment 22 to contain the dye, which substantially consists of two cylindrical zones 23 and 25 (FIG. 2) and an intermediate zone 26 which connects the two cylindrical zones 23 and 25 to each other.

Each of the two cylindrical zones 23 or 25 has a size and an internal containing volume that are substantially equivalent to those of a traditional container, indicated in its entirety by the reference number 110 in FIGS. 4 and 5. The distance “D2” between the longitudinal axes “X2” of the two cylindrical zones 25 or 23 is equal to the distance “D1” between the two axes of delivery “X1” of a pair of delivery stations 18.

In this way it is possible to install the container 10 according to the invention on the dispensing machine 11 without varying the normal lay-out of the delivery stations.

Moreover, inside every cylindrical zone 23, 25 a stirrer device 27 is axially provided, which comprises a plurality of radial blades 29, mounted on an axially rotating shaft 30. The stirrer device 27 is able to keep the dye contained in the tank 13 in constant movement, so as to prevent the homogeneity and stability of the dye from deteriorating.

The intermediate zone 26, as we said, is able to connect the two cylindrical zones 23 and 25 to each other, and is shaped so as to reduce to a minimum the so-called “dead stirring zone”, wherein the action of the stirrer devices 27 has a limited effect.

The inner compartment 22 of the tank 13 thus formed has a greater capacity of the intermediate zone 26 compared with two inner compartments of two traditional containers 110, therefore the frequency at which it has to be filled or topped up is reduced.

The two outlet pipes 15 and 16 are mounted on a bottom wall 31 of the tank 13, respectively in correspondence with the two cylindrical zones 23 and 25, in order to allow the dye to exit from the inner compartment 22. In this case, the two outlet pipes 15 and 16 are mis-aligned with respect to the longitudinal axes “X2” of the relative cylindrical zones 23 and 25, to allow the axial housing of the respective stirrer devices 27 inside the tank 13.

According to a variant, not shown in the drawings, the two outlet pipes 15 and 16 can be arranged coaxial with the respective cylindrical zones 23 and 25. In this case the stirrer devices 27 are mis-aligned with respect to the relative axis X2. Each of said outlet pipes 15 and 16 is provided at its lower end with a sealing valve, of a known type and not shown in the drawings, able to keep the passage normally closed for the dye. The sealing valve is automatically opened at the moment of the axial connection along the axis of delivery “X1” with the relative suction pump 17.

FIG. 4 shows a lay-out of the traditional containers 110 in the dispensing machine 11, while FIG. 5 shows the same dispensing machine 11 on which some containers 10 according to the present invention are installed. If we compare FIG. 4 and FIG. 5, we see that the installation of the containers 10 according to the invention does not entail any increase in the overall bulk of the dispensing machine 11, nor any revision of the initial lay-out.

It is clear, however, that modifications and/or additions may be made to the container 10 as described heretofore, without departing from the field and scope of the present invention. For example, according to a variant, the container 10 can be associated with a single suction pump 17, or with two pumps in order to increase productivity, without worsening the resolution and precision of the dye prepared.

It also comes within the field of the present invention to provide that every suction pump 17 can be associated directly with the container 10, and then connected with the respective delivery station 18.

It is also clear that, although the present invention has been described with reference to specific examples, a person of skill in the art shall certainly be able to achieve other equivalent forms of container to contain fluid products, having the characteristics as set forth in the claims and hence all coming within the field of protection thereof.
