DETAILED DESCRIPTION

[0045] The following detailed description refers to particular embodiments of bag 1 of the present utility model, without limiting its content.

[0046] The bag 1 of the present utility model is suitable for containing cement, or other similar material useful in the construction, or in the food, mineral, chemical sectors, such as for example sand, gravel, or other useful material, for example, in the animal feed and seeds or similar sectors.

[0047] In a first embodiment shown with reference to FIGS. 2-5, a bag 1 is shown, consisting of an external lateral surface 2 and a bottom 3 so that the bag 1 is made up of a single body. The bottom 3 has a flat, partially rigid surface, so as to facilitate placing the bag 1 on the ground on flat surfaces when the bag is full, or partially full. The bag 1 then assumes a vertical position when the bottom 3 is placed on the ground.

[0048] The bottom 3 is made up of a first flap 3a and a second flap 3b which are arranged so as to form and close the bottom 3 and so as not to overlap one each other. An empty area 4 is thus formed between the first flap 3a and the second flap 3b. The empty area 4 is substantially rectangular in shape, with a minimum distance between the two flaps varying in the range from 15 to 50 mm, preferably from 20 to 40 mm, for example approximately 30 mm (see FIG. 3).

[0049] A covering element 5 is applied to the two flaps 3a and 3b, before they are closed, so that the empty area 4 between the two flaps 3a and 3b is also covered (see FIG. 4). At the same time, by applying the covering element 5 to the bottom 3 made up of the two flaps 3a and 3b, a good seal is obtained to avoid unwanted leakage of the material contained inside the bag 1 through any elements of the flaps 3a and 3b that are not perfectly sealed. The covering element 5 is made of transparent plastic material or transparent papers.

[0050] On the transparent covering element 5, after closing the bottom 3, a reinforcing element 6 (also called fondello) is applied, made of paper and provided with a window (or punch, or through opening) 7 suitable for being positioned in correspondence with the empty part 4 between the first flap 3a and the second flap 3b of the bottom 3 (see FIG. 5).

[0051] In this way, the user can see the inside bag contents (going from the bag outside towards the bag inside) through the window or opening 7 obtained in the reinforcement element 6, the transparent covering element 5 and the empty area 4 between the first flap 3a and the second flap 3b.

[0052] At the same time, in this first embodiment, thanks to the fact that the reinforcing element 6 is made of non-transparent paper, the various elements making up the bag, necessary for its formation and closure, are covered. In this way, the aesthetic bag shape is made more pleasant, while still allowing the contents placed inside the bag to be viewed from the outside thanks to the window 7 obtained in the reinforcing element 6.

[0053] In a second embodiment of the present utility model with reference to FIG. 6, the same bag as in FIGS. 2-5 is shown, where the reinforcing element 6 is transparent.

[0054] In this second embodiment, the user can see the contents inside the bag through (going from the bag outside towards the bag inside) the transparent reinforcement element 6, the transparent covering element 5 and the empty area 4 between the first flap 3a and the second flap 3b.

[0055] In a third embodiment of the present utility model with reference to FIGS. 7-9, a bag similar to the bag shown in FIGS. 2-6 is shown. However, unlike the embodiments shown above with reference to FIGS. 2-6 where the first flap 3a and the second flap 3b of the bottom 3 are not superimposed on each other leaving the empty area 4 between them, in FIGS. 7-9 the first flap 3a and the second flap 3b of the bottom 3 are at least partially overlapped with each other.

[0056] Furthermore, in the embodiment shown in FIGS. 7-9, each of the first flap 3a and the second flap 3b is provided, in correspondence with a central part thereof, with a cutout 8a, 8b (see FIG. 7). In this way, when the first flap 3a partially overlaps the second flap, the cutouts 8a, 8b collectively create the empty area 4 in the non-overlapping part of the first flap 3a and the second flap 3b. In particular, the cutouts 8a, 8b are substantially semi-circular in shape; in this way, the empty area 4, which is created in the non-overlapping part when the first flap 3a partially overlaps the second flap 3b, is substantially circular in shape.

[0057] Also in the embodiment shown in FIGS. 7-9, to seal the product bagged inside the bag, before closing the flaps 3a and 3b, a transparent covering element 5 is first applied to them (see FIG. 8), and then a reinforcing element 6 made of paper and provided with a window (or punch, or through opening) 9 capable of being positioned in correspondence with the empty part 4 between the first flap 3a and the second flap 3b of the bottom 3 is applied thereto (see FIG. 9).

[0058] In this third embodiment, the user can thus see the contents inside the bag through (going from the bag outside towards the bag inside) the window (or opening) 9 obtained in the reinforcing element 6, the transparent covering element 5 and the circular empty area 4 formed by the semi-circular cutouts 8a, 8b.

[0059] At the same time, also in this third embodiment (as already seen above with reference to the first embodiment), thanks to the fact that the reinforcing element 6 is made of non-transparent paper, the various elements making up the bag, necessary for its formation and closure, are covered. In this way, the bag aesthetic shape is made more pleasant, while still allowing the contents placed inside the bag to be viewed from the outside thanks to the window 9 obtained in the reinforcing element 6.

[0060] In a further embodiment shown in FIG. 10, the reinforcing element 6 is transparent.

[0061] In this way, the user can see the contents inside the bag through (going from the bag outside towards the bag inside) the transparent reinforcement element 6, the transparent covering element 5 and the empty circular area 4 formed by the semi-circular cutouts 8a, 8b.

[0062] Of course, many modifications and variations of the preferred embodiments described above will be apparent to those skilled in the art, while still remaining within the scope of the utility model.

[0063] Therefore, the present utility model is not limited to the preferred embodiments described, illustrated for illustrative and non-limiting purposes only, but is defined by the following claims.
