Description

Bag with handle

This patent is related to plastic container bags and, in particular, is related to a new container bag made of plastic material, particularly suitable for food products for animal use, equipped with a single loop or double loop handle.

As is known from the prior art, there are container bags made of at least one sheet or a continuous support, for example made of plastic material, which is processed in various stages including folding, cutting and sealing, to obtain a bag with a closed bottom and an opening to fill the bag from above, opposite the bottom, which after the filling operation is closed and sealed.

As is known from the prior art, there are container bags containing at least one handle generally located near said opening to fill the bag, that is, on the top edge of the bag, opposite the bottom.

As is known, there are large bags, such as bags intended to contain food products for animal use, and where said upper handle is therefore at a significant distance from said bottom.

Therefore, the operations involved with the displacement of the bag are uncomfortable, because the user, particularly if he is short, cannot lift the bag from the ground by simply grasping it from said upper handle.

To solve this problem, container bags are known where the handle is not located on the top edge of the bag, but on a vertical surface of said bag, usually on one side, in an intermediate position between the bottom and the top edge, of so that the user can transport the bag horizontally instead of vertically, and therefore with less effort and greater maneuverability.

Handles made of a strip of heat-sealed plastic material at the ends of the outer surface of the bag and preferably positioned in the direction of the height of said bag are known.

EP 2 035 288 concerns a container bag made of plastic material that has side walls with inserted reinforcements, where the handles are made from two openings next to each other, made in the inserted reinforcements of one of said walls lateral. To prevent the material contained in the bag from exiting said openings, at least one additional label or sheet is applied inside said bag, in correspondence with said openings, to close them.

Other known container bags have the handle comprising a tape internally attached to the bag and accessible from the outside through an opening in said bag, which has substantially the dimensions of said handle, said opening being sealed from below by means of a label applied inside said bag.

Solutions similar to that mentioned above are described, for example, in patent applications WO 2008/145164, EP 0553693, US 2006/0188178.

United States Patent No. 2009/022430 discloses a packaging bag comprising a panel with two holes, a reinforcement strip covering said holes, and a handle, wherein said handle 28 is attached to the reinforcement strip through said holes.

EP 1712482 discloses a bag made of thermoplastic material, which has holes closed by an internal strip, where a handle with its opposite ends is fixed to said internal strip, through said holes.

In known bags, said handles are applied to the bag during the continuous production cycle of said bag, where said production cycle provides for the perforation or cutting of the sheet or support material in the area where the handle is applied, constituting the handle the application of a strip, which is heat sealed at its ends to the foil or support surface facing the inside of said bag, and the application of a label to close the hole.

When the bag is made, filled and ready for use, the user must first remove any possible portion of the perforated sheet to access the handle from the outside of the bag, while the sealing label applied to the inside of said bag guarantees the tightness of the seal of said bag.

Known bags for container use have a single handle on one side, placed substantially centrally with respect to the height of said bag.

Known bags for container use have at least one opening to access its contents, placed along the top of the bag, near a corner, to facilitate the operation of pouring its contents.

To perform said operation, the user must grab said bag, lift, tilt and tip it to direct the opening down to pour the contents of the bag.

Therefore, the user must use the single-sided handle to tip the bag.

This operation is very convenient especially with very heavy or very large bags, since users can easily place the bag horizontally by gripping the single side handle, but then they may not be able to tilt said bag even more, without grasping the bag itself.

In addition, the handle on a single side is particularly inconvenient, especially for large or heavy bags, because when the bag is raised using the handle, the handle itself deforms in a U-shape, leaving little space for the hand, whose fingers are crushed .

In addition, since the handle is really anchored to the bag at two points, corresponding to its two ends, the tensile forces generated during the lifting, transport and handling of the bag using said handle, are concentrated in said two points, with the risk of breakage of the handle itself or of the sheet or support material that constitutes the bag.

The object of this patent is a new type of plastic container bag, particularly suitable for food products for animal use, equipped with a double loop handle.

The main objective of this invention is to make the transport and handling of the bag less difficult and uncomfortable.

Another objective of this invention is to allow the bag to tip over more easily during the operation of pouring its contents.

Another objective of this invention is to ensure a better distribution of tensile forces in at least three points or areas of the sheet or support material comprising the bag, making it easier for the user to grasp and also reducing the risk of breaking said handle. or said sheet or support material comprising the bag.

These and other objectives, whether direct or complementary, are achieved with a new plastic container bag, particularly suitable for food products for animal use, equipped with a double loop handle.

The new container bag comprises at least one handle located on one side of said bag, in an intermediate position between the bottom and the upper edge of the bag itself, and wherein said handle comprises at least one tape directly attached to said bag in at least three points or zones that create two loops.

The sheet or support material constituting said bag comprises at least three holes, with a single closure tag of said holes applied to the inner surface, and where said handle is attached at both ends, and at a central point of said label of close, in said three holes, leaving the unbound part of the handle out of the bag.

Therefore, in practical terms, said handle is attached to said bag at least at its two opposite ends and at a central point, in order to create two loops, preferably symmetrical with respect to said center point, so that the user can insert the hand with two fingers in a loop and two fingers in the other loop, distributing the tensioning forces during the lifting, transport and handling of the bag.

This handle is substantially centered with respect to the height of the bag and, in particular, said intermediate fixing zone is preferably centrally positioned, so that said two loops move in comparison with said central position and, in particular, with a first loop, which is positioned closer to the bottom of the bag, below the center point or center of gravity of the bag, and a second upper loop, which is positioned farther from the bottom of the bag, above the center or center point of gravity of the bag.

Therefore, the user can grasp both loops with one hand, as described above, and tilt the bag from the vertical to the horizontal position.

Then, as a result of the two loops moving relative to the center of gravity or center point of the height of the bag, the user can tilt the bag further to pour its contents by raising the bottom, simply acting on the lower loop only.

The characteristics of the new bag will be clearer through the following description with reference to the drawings, which are attached by way of non-limiting example.

Figure 1 shows a section of a bag (S) in correspondence with a handle (C) with a single loop (C2), of a reference example that is not part of the invention.

Figures 2 and 3 respectively represent a handle (C) in an embodiment of the present invention, which has a double loop (C2, C4) and a closing tag (B), where the sealing areas and / are indicated. or union.

Figure 4 is a diagram with the distribution of three holes (A1, A2, A3) made in the sheet or support material (A) constituting a bag (S), in accordance with the present invention.

Figure 5 shows a section of a bag (S) in correspondence with a handle (C) having a double loop (C2, C4), in accordance with the present invention.

Figures 6a and 6b are diagrams depicting the use of a bag (S) with a handle (C) having a double loop (C2, C4), in accordance with the present invention.

This is a container bag (S) made with at least one sheet or support material (A), such as plastic material, which undergoes successive bending, cutting and welding operations, to make a wrap that can be closed several times, as is depicted in figures 6a and 6b.

The bag (S) comprises a closed bottom (S1), at least one opening (S2) on the opposite end of the bag (S), side walls, two of which are larger opposite walls (S3) and two of the which are side walls (S4), such as side walls of inserted reinforcements.

The bag (S) is particularly useful and usable to contain the intended food products, for example for animal use, preferably in granulated form.

The new container bag (S) comprises at least one handle (C) applied on the outside of said bag (S), on at least one side (S4), in a substantially intermediate position between the bottom (S1) and the upper opening (S2).

In detail, said handle (C) includes at least one band, represented in Figure 2, placed substantially parallel to the reinforcement inserted, that is, in the direction of the height of the bag (S).

As illustrated in Figure 1, which represents a reference example, on said sheet or support material (A) constituting said bag (S), there are at least two holes (A1, A3), that is, at least one hole for each zone or anchor point for the handle (C).

In correspondence with said holes (A1, A3), at least one label (B) is applied to close said holes (A1, A3) and it is sealed on the surface (A4) of the looking sheet or support material (A) into the bag (S).

Said handle (C) is attached to said label (B) from outside the bag (S) at two opposite ends (C1, C5), in correspondence with said two holes (A1, A3) of said sheet or material (A ) of support, so that the sheet or support material (A) is really sandwiched between the label (B) and said handle (C).

According to the present invention, as illustrated in Figure 4, on said sheet or support material (A) constituting said bag (S), there are at least three holes (A1, A2, A3), that is, at minus one hole for each point

or anchor zone for the handle (C).

In correspondence with said holes (A1, A2, A3) a single closing label (B) is applied for said holes (A1, A2, A3) and sealed on the surface (A4) of the sheet or material (A) of support that looks into the bag (S).

As illustrated in Figure 5, said label (B) is sealed to said sheet or support material (A) along the perimeter (B1), illustrated in Figure 3 with a dotted line, by heat sealing or glue (B11).

Said handle (C) is attached to the label (B) from outside the bag (S) in at least three zones (C1, C3, C5), that is, as illustrated in Figure 5, at two opposite ends (C1, C5) and in an intermediate zone (C3), corresponding to said three holes (A1, A2, A3) made on said support sheet or material (A), such that the support sheet or material (A) It is really sandwiched between the label (B) and the handle (C).

In particular, said handle (C) is, for example, heat sealed (D11, D21, D31) and / or glued (E11, E21, E31) in at least three zones.

In particular, as illustrated in Figure 2, the embodiment provides that said handle (C) is heat sealed to the label (B), in correspondence with the zones (D1, D3) for example substantially to C in both ends (C1, C5) and with an additional zone (D2) substantially in the center (C3) of the handle (C).

Another embodiment can also provide as an alternative, or preferably in combination with said heat sealing method, that said handle (C) is attached to the label (B) by means of a corona and glue treatment in the areas ( E1, E3) at the two opposite ends (C1, C5) and at least in an area (E2) located substantially in the center (C3) of the handle (C).

Thus, as illustrated in Figure 5, the handle (C) thus attached to the label (B) creates at least two loops (C2, C4) placed on both sides with respect to the central part (C3) of said handle (C).

As can be seen in Figures 6a and 6b, said handle (C) is placed on said bag (S) in a substantially central position along the height of the bag (S), or substantially aligned with the center of gravity

5 of the bag (S), such that said central part (C3) of the handle (C) is substantially aligned with the center point of the height of the bag (S) or center of gravity, while one of said loops (C2), or upper loop, is closer to said opening (S2) of the bag, and the second of said loops (C4) or lower loop, is closer to said bottom (S1).

To carry the bag (S) in a horizontal position, as illustrated in Figure 6a, the user grabs both of said

10 loops (C2, C4) of the handle (C) with one hand, for example with two fingers in a loop (C2) and two fingers in the other loop (C4), distributing the tensile forces evenly over these three joining areas ( C1, C3, C5) of the handle (C) with said label (B).

To further dump the bag (S), as in Figure 6b, by tilting said upper opening (S2) down to pour the contents of the bag (S), the user can raise the bottom (S1) of the bag (S) acting on said lower loop

15 (C4), which is offset from the center of gravity or midpoint of the bag (S).

Therefore, with reference to the preceding description and the accompanying diagrams, the following claims are constructed.
