DESCRIPTION OF THE DRAWINGS

[0012] To complement the description being made and with the aim of assisting in a better understanding of the features of the invention, a set of drawings is attached wherein the following is represented for illustrative and non-limiting purposes.

[0013] FIG. 1: Side view of a container according to an example embodiment.

[0014] FIG. 2: Detail of an example embodiment in an open condition.

[0015] FIG. 3: Detail of the previous example in a closed condition.

DETAILED DESCRIPTION OF THE INVENTION

[0016] Next, an embodiment of the invention will be briefly described as an illustrative, non-limiting example thereof.

[0017] In FIG. 1, an example embodiment made up of a container with an approximately cylindrical wall (1), a lower base (2) and an upper base (3) can be seen. The two bases (2,3) have a matching shape so that similar containers can be stably stacked. The lower base (2) is concave, and the upper base (3) is convex and protrudes at a shorter distance than the lower base (2) to allow it to be inserted in the lower base (2) of a can placed thereon. Generally, the upper base (3) is surrounded by an indentation, as is typical for this type of container.

[0018] Similar to the above-mentioned utility model, the can's opening tab (4) is located at the maximum of the upper base (3) and possesses an opening pull ring (5). The edge of the tab (4) is frangible along all or part of its perimeter to define the pouring aperture.

[0019] A flange 6 is arranged around the tab (4), useful both to increase the mechanical resistance and to serve as a pouring edge, in such a way that the indentation in the upper base (3) does not come into contact with the liquid. The portion of the upper base (3) within the flange (6) is preferably flat. The flange can be made similarly to the flange of each base (2, 3), i.e., by overlapping and folding the edges of each part. Thus, the upper base (3) is made in two pieces, one in the form of an annulus (31) between the wall (1) and the flange (6) and a circular one or the lid (32) where the aperture is defined (FIG. 3). The annulus can be made of a different material from the inside of the flange (6), which requires a more carefully selected material. That is, the material of the annulus

[0020] As can be seen in the figures, the wall (1) is not cylindrical, but has a neck (11) with a reducing diameter in the area close to the upper base (3). The neck (11) is made by means of rollers prior to producing the can.

[0021] To open the can, the ring (5) is lifted, on the side opposite to its attachment to the tab (4), which allows the can to be ventilated. Subsequently, the ring (5) is pulled and the tab (4) breaks along its perimeter through a fracture or weakening line. The tab (4) and the ring (5) can be positioned on the other side of the flange (6). At this point, the liquid can be dispensed, not coming in contact with the outside of the can at any time and avoiding contamination. In particular, impurities built up at the junction of the upper base (3) and the wall (1) are prevented.

[0022] Furthermore, due to the definition of the annulus (31) and the lid (32), different materials can be used in each portion, leaving the high-performance material solely for the lid (32). For example, 5XXX series aluminum can be used for the lid (32) and 3XXX series aluminum for the remaining parts.

[0023] The force needed to open the lid (32) can be made using the ring (5) with a single movement and only one hand.
