Description
FIELD OF THE INVENTION

This utility model refers to a bag for transporting materials. In particular, the present utility model refers to a bag for transporting cement, or other useful material in various food, chemical and construction sectors, having a reinforcing element equipped with a window useful for looking at the bag inside.


STATE OF THE ART

Currently, for transporting cement and other similar material in the construction sector, as well as for transporting other goods such as in the food, chemical and mineral sectors, paper and plastic bags are typically used.


Such bags generally consist of a main external surface and at least one bottom fixed to the main external surface, so that the bag is made up of a single body. The consistency of the bag external surface typically allows the bag itself to take on the shape defined by the material mass contained therein.


Typically, in the known in the art bottom bags, the bottom is created by folding two flaps of the bag body, completely overlapping one each other, as shown in FIG. 1. This complete overlap thus allowing a continuous surface, without openings; gluing one flap onto the other completely seals and reinforces the bottom closure.


The French Patent No. FR 1.362.4573 describes bags having a round or polygonal shaped window closed by a transparent, plastic or other material sheet placed on the bag bottom.


However, in certain situations, the user of these bags needs to see from the outside the bag content placed inside, in the area corresponding to the bottom.


Therefore, the Applicant has faced the technical problem to effectively and economically produce a bag to improve the visibility of the bag contents at the bag bottom.


SUMMARY

In a first aspect, the present utility model refers to as the one indicated in claim 1.


The Applicant of the present application has in fact surprisingly found that the technical problem encountered above can be effectively and reliably solved by means of a bag consisting of a single body formed by an external surface and at least one bottom fixed to said external surface, wherein:

    • said bottom is made up of a first flap and a second flap which are arranged so as not to overlap one each other or to only partially overlap one each other to create in any case at least an empty area between said first flap and second flap,
    • said bag also includes a transparent covering element applied to said bottom before closing the two flaps and arranged so as to cover at least said empty area,
    • said bag is also provided with a reinforcing element (also called “fondello”) applied to said transparent covering element.


Furthermore:

    • at least the portion of said reinforcing element capable of being positioned in correspondence with said empty part of the bottom is made of transparent material, and/or
    • said reinforcing element is provided with a window or opening suitable for being positioned in correspondence with said empty part of the bottom.


In this way, the bag user has the possibility of seeing the contents placed inside the bag from the outside through the empty area left free between the two flaps making up the bag bottom.


In fact, the covering element covering the bottom empty area is transparent, and therefore the bag inside in correspondence with the empty area is allowed to be seen through it even after the covering element has been applied to the bottom.


At the same time, by applying the covering element to the bottom, a good seal is obtained to avoid unwanted leaks of the material contained inside the bag through any elements of the bottom that are not perfectly sealed.


Furthermore, in any case, whether the reinforcing element is also transparent, or whether it is instead provided with a window, hole or punched opening capable of being positioned in correspondence with the empty part of the bottom, the bag inside will be always visible from the outside in correspondence with the empty area between the two flaps making up the bottom even after the reinforcing element has been applied to the covering element.


In fact, if the reinforcing element is transparent, it is applied to the covering element which is transparent, and therefore there will be no element that will prevent the user from seeing the bag inside through the empty area created between the two flaps making up the bottom.


Conversely, if the reinforcing element applied to the transparent covering element is not transparent but is provided with a window, hole or punched opening, arranged in correspondence with the empty area created between the two flaps constituting the bottom, this opening allows, given that the covering element is transparent, to still see the bag inside through the empty area created between the two flaps making up the bottom.


According to a preferred embodiment, said reinforcing element provided with a window or opening capable of being positioned in correspondence with said empty part of the bottom is made of non-transparent paper.


In this way, thanks to the fact that the reinforcing element 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 content placed inside the bag to be viewed from the outside thanks to the window created in the reinforcing element itself.


According to a preferred embodiment, said empty area between the two flaps is substantially rectangular, octagonal, circular, or oval shaped.


According to a preferred embodiment, said empty area between the two flaps is substantially rectangular shaped with a minimum distance between the two flaps varying in the range from 15 to 50 mm, preferably from 20 to 40 mm.


According to a preferred embodiment, said first and second flaps do not overlap one each other so as to leave an empty area of variable dimensions between them.


According to a preferred embodiment, each of said first flap and said second flap is provided, in correspondence with a central part thereof, with at least one cutout so that, when said first flap and said second flap partially overlap one each other, said cutouts overall create said empty area in the non-overlapping part of said first and second flap.


In this way, even if the two flaps making up the bottom are partially superimposed one each other, there is always an empty area between the two flaps making up the bottom, which acts as a window or opening to allow the user to see the bag inside through it.


According to a preferred embodiment, each of said cutouts is substantially semi-circular shaped so that, when said first flap and said second flap partially overlap each other, said empty area created in the non-overlapping part of said first flap and the second flap is substantially circular shaped.


According to a preferred embodiment, said transparent covering element is made of transparent plastic material or transparent papers.


According to a preferred embodiment, said reinforcing element has substantially the same shape as said bottom.


According to a preferred embodiment, said bottom and said reinforcing element are substantially rectangular shaped.


According to a preferred embodiment, said bag bottom has a flat, at least partially rigid surface.

DETAILED DESCRIPTION

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


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.


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.


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).


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.


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).


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.


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.


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.


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.


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.


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.


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).


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.


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.


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


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.


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.


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.
