This border is essentially composed of an intermediate polymer layer (20) that provides a barrier against oxygen and flavor. This layer is sensitive to moisture, and on each face of this intermediate layer is one or more polymer layers (1 12 14 10) of polyolefin. All layers are continuously bonded. Importantly, the segments of the layers on the inner faces of the intermediate barrier layer (1 21) have a total thickness between 0 and 150 µm, allowing for better retention of the flavor of the product contained within. The tube should be designed to contain one or two pathways for facilitating and complete dispersion of the product contained within. It is used in the packaging industry for liquid, cream, or paste products.

Claims

1. A tube (B C34 36) is used to contain and distribute a product containing a strong aroma and water. It contains a product dispensing head (38 and 35) attached to a flexible inner tube. The inner tube contains, essentially, an intermediate polymer layer (20) which acts as a barrier against oxygen and flavor or aroma. This layer is sensitive to moisture, and on each face of this intermediate layer there are one or more polymer layers with a polyolefin base (1 100 13 11 and 12 14 10). These layers are continuously connected. Importantly, the segments of the layers placed on the inner faces of the intermediate barrier layer (1 21 100 13 11 21) have a total thickness between 40 and 150 micrometers, which improves the retention of the aroma and flavor of the product contained or potentially contained in the tube.

2. The tube pursuant to claim 1, where the total thickness of the aforementioned layers (1 21 100 13 11 21) placed on the inner face of the intermediate layer is between 55 and 140 micrometers, the presumed thickness to be used being between 65 and 130 micrometers.

3. Tubes under either claim 1 or 2 where the polymer layer, which has polyolefin as the base material, is on one side a low density (1) or very low density or linear low density polyethylene (100) with a specific mass between 0.86 and 0.93 g/cm² and on the other side is a low density polyethylene (LDPE) with a specific mass between 0.90 and 0.93 g/cm² or high density polyethylene (HDPE) with a specific mass between 0.935 and 0.97 g/cm² (13 14).

4. Tubes (34 36) pursuant to claim 3, in which such layer of polyethylene shall have one or more layers of HDPE (13 14) with a total thickness of at least 90 micrometers.

5. Tubes according to claim 4 where the sum of such thicknesses of the HDPE layer (13 14) is between 100 and 140 micrometers and such thickness of the edge is between 260 and 380 micrometers.

6. Tubes according to claim 4 where the sum of twice the thickness of such cross-sectional layer (20) and such thickness of such layer of HDPE (13 14) is between 100 and 140 micrometers. The thickness of such cross-sectional layer is between 130 and 180 micrometers. The thickness of such cross-sectional layer is between 260 and 380 micrometers.

7. A tube under any of the claims 3 through 6 in which such polyethylene layer consists of a first layer (13) HDPE which is inserted between such inner surface layer (100) and an intermediate layer (11) of LDPE which by itself sits on the inside of the intermediate barrier layer (20).

8. A tube pursuant to any of the claims 3 through 7 in which such polyethylene layer consists of a second (14) layer of HDPE which is inserted between the outer (10) layer of LDPE and a second (12) intermediate layer of LDPE which by itself is on the outside of the intermediate barrier layer (20).

9. A tube under either claim 7 or 8 in which the first (13) layer of HDPE and/or the second (14) layer of HDPE are in a continuous state in connection with the said LDPE layer (100 11 12 10) in which it is inserted.

10. Tubes (34 36) pursuant to claim 8 where the thickness of the first and second layers (13 14) of HDPE is between 10 and 50 micrometers and between 60 and 140 micrometers, respectively.

11. Tubes (34 36) in accordance with claim 10 in which the interlayer between the first and second layers (11 13) of each LDPE layer is connected to the face of the intermediate barrier layer (20) by the binding layer (21 22) of EAA or EMA.

12. Any tube under any of the claims 1 to 11 in which the intermediate layer (20) of the tube is made of material of the EVOH, PVOH, PA and PA group that has been modified and has a thickness between 0.01 and 0.05 mm.

13. Tube (34 36) under any one of the above claims, where the distribution head (38 and 35) is fitted with a neck (35) of a diameter less than the flange and a round shoulder (38) connected to the neck (35) by the flange. Such shoulder is between 0.9 times and 1.35 times the thickness of the flange and creates a continuation of the structure with such flange and consists of a folded section which is compressed flat and welded together. Such shoulder (38) can be compressed laterally.

14. (36) According to claim 13, where the folded part of the said shoulder, which is pressed flat and joined together, has an extended section (39 41) of the layer that provides a barrier between (20) the said shoulder, which is folded and pressed flat (Clause 14, page 3, Figure 10).
