The present invention relates to a container, particularly suitable for containing water-based liquids and the like.

As is known, pots, particularly pots intended to contain paints and the like, are constituted by a main body that is generally cylindrical with a circular base, is made of plastic material and has a metallic ring that delimits the mouth for access to said container.

This metallic ring, which is generally clinched to the internal wall of the body of the container and is made of a ferrous material, is adapted to accommodate a press-on closure so as to form a hermetic seal.

These containers of a known type are not free from drawbacks, which include the fact that since the substances contained therein are water-based, the metallic ring and the closure, if made of ferrous materials, are subject to oxidation, which leads to the forming of rust.

Another drawback of containers of the known type resides in that they normally cannot be stacked one inside the other, since their flat bottom allows mutual sliding, with consequent collapse of the stack of containers.

A further drawback of containers of the known type resides in the fact that the metallic ring generally protrudes inward with respect to the walls of the body of the container, and this characteristic does not allow complete and correct emptying of said container, since a point of accumulation of the contained substance is formed.

The aim of the present invention is to provide a container, particularly suitable for containing water-based liquids and the like, that is not subject to oxidation of its parts, so as to have a longer life than containers of the known type and not to alter the physical-chemical properties of the contained substance.

Within this aim, an object of the present invention is to provide a container that can be stacked easily. Another object of the present invention is to provide a container, particularly suitable for water-based liquids and the like, that is highly reliable, relatively simple to provide and has competitive costs in comparison to the background art.

This aim and these and other objects that will become more apparent hereinafter are achieved by a container, particularly suitable for containing water-based liquids and the like, comprising a containment body which has an upper mouth delimited by a metallic ring that is associated with said containment body and can be engaged by pressing with a closure, characterized in that said metallic ring is provided partly by a sealed band that is plastic-coated at least at the region of said metallic ring that is adapted to face the inside of said containment body to prevent direct contact of the water-based liquid substance contained in said containment body with said metallic ring.

Further characteristics and advantages of the invention will become more apparent from the description of a preferred but not exclusive embodiment of a container, particularly suitable for containing water-based liquids and the like, according to the invention, illustrated by way of non- limiting example in the accompanying drawings, wherein:

Figure 1 is an exploded perspective view of an embodiment of the container according to the invention;

Figure 2 is an enlarged- scale view, along an axial sectional plane, of a detail of the container according to the invention;

Figure 3 is a longitudinal sectional view of two stacked containers according to the invention;

Figure 3 a is a longitudinal sectional view of two stacked containers according to a variation of the invention;

Figure 4 is a longitudinal sectional view of the two containers shown in Figure 3 and mutually spaced.

With reference to the figures, the container particularly suitable for containing water-based liquids and the like, generally designated by the reference numeral 1, comprises a containment body 2 made of plastic material, such as for example polypropylene, that has a cylindrical shape with a circular base and is provided with an upper mouth 3 delimited by a metallic ring 4 that is made for example of a ferrous material and is associated with the containment body 2 and can be engaged by pressing with a closure 5.

According to the invention, the metallic ring 4 is provided partly by a sealed band 8a that is plastic-coated at least at the region of the metallic ring 4 that is adapted to face the inside of the containment body 2 to prevent direct contact of the water-based liquid substance contained in the containment body 2 with the metallic ring 4.

Advantageously, the closure 5 has a disk-like shape and comprises an inner edge 6 that protrudes in an axial direction, is adapted to be inserted in the upper mouth 3 and is such as to form an outer abutment ring 7.

More precisely, the closure 5 can be also made of a ferrous material. In this case, it is covered by a plastic-coated layer 8b that is formed at least at the region of the closure 5 that is adapted to face the inside of the containment body 2 to prevent direct contact of the water-based liquid substance contained in the containment body 2 with the plug 5.

As regards the metallic ring 4, it is clinched to the upper mouth 3 so as to be flush with the inner wall 9 of the containment body 2 and so as to form a circular groove 10 that is radially internal to the internal wall 9.

Furthermore, at the lower base 11 of the containment body 2 there is a circular rim 12 that protrudes axially from the lower base 11 and is complementary to the circular groove 10 for the stable stacking of two containers 1, as shown in Figures 1 and 2.

Advantageously, the body of the container 1 can taper slightly and in this case, as shown in Figure 3a, the circular edge 12 is an extension of the container body and rests against the circular groove 10 of said underlying container, when two containers are stacked.

In practice it has been found that the container according to the invention achieves fully the intended aim and objects, since it prevents direct contact between the aqueous substance contained therein and parts thereof that are subject to rusting.

Another advantage of the container according to the invention resides in the fact that it can be stacked easily in a stable manner.

The container, particularly adapted for containing water-based liquids and the like, thus conceived, is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims.

All the details may furthermore be replaced with other technically equivalent members.

In practice, the materials used, as well as the contingent shapes and dimensions, may be any according to the requirements and the state of the art.
