Definitions
- the invention is in the field of flexible tubes or pouches formed by means of plastic films. It relates more specifically the flexible tubes or pockets whose ends are welded end to end.
- FIG. 1 illustrates a solution described in the application WO20071 13781.
- a tubular packaging body 1 is formed from a multilayer flexible film 2 having a intermediate layer 4 whose butt welding is only partial or nonexistent.
- the patent application WO20071 13781 describes the use of a reinforcing strip 7 of fine thickness and high strength.
- the strip 7 is welded to the lower layer 5 of the multilayer film and connects the two welded ends of the laminate.
- the packaging thus obtained has a high tensile strength, bursting or tearing at the zone 6 thanks to the properties of the reinforcing strip 7.
- the patent application EP0177470 describes the use of a reinforcing strip welded inside the tube and connecting the ends of the film welded end to end. It proposes a band of large width containing a thick aluminum foil giving the plastic tube a deformation behavior similar to that of an aluminum tube (no springback). This band is at least 10% of the circumference of the tube and mainly modifies the behavior of the tube (stiffness) in the direction of the axis of the package.
- a tube made according to the patent application EP0177470 has the major disadvantage that the packaged product is in contact with the aluminum layer of the reinforcing strip. Direct aluminum - product contact is generally avoided in the field of packaging and mainly for liquid or pasty products packed in tubes.
- FIG. 2 shows that, despite the rupture of the butt weld, the packaging retains its seal thanks to the properties of the strip 7.
- the appearance of this defect may lead to believe that user that the packaging is of poor quality or defective.
- Multilayer film film with several layers.
- the multilayer film can be obtained by coextrusion or / and lamination.
- PET bi-oriented polyethylene terephthalate
- BOPP bi-oriented polypropylene
- PA polyamide
- PE polyethylene
- LLDPE linear low density polyethylene
- HDPE high density polyethylene
- EVOH ethylene vinyl alcohol
- Adhesive glue used to combine several layers by complexing
- the invention consists in adding at the butt joint a reinforcement element having the effect of rendering the weld zone dimensionally stable perpendicular to the welded ends without substantially modifying the flexibility of the welded zone in the direction tangential to the welded ends.
- the reinforcement element added at the end-to-end weld is invisible and imperceptible. It is invisible because located inside the packaging. It is imperceptible because its small size does not significantly alter the flexibility of the packaging.
- the reinforcement element added at the butt weld is made of plastic.
- the weld zone is made indeformable locally and in the direction perpendicular to the welded ends by the addition to the inside of the package of a reinforcing element which is indeformable under the action of the fingers in the direction perpendicular to the axis of the reinforcing element, and easily deformable in the direction of the reinforcing element.
- the height h is equal to or greater than the thickness e of the film
- the ratio (le) / h 2 is between 1 and 10.
- the invention consists of a tubular packaging formed of a flexible film welded end to end and comprising at the weld an invisible and imperceptible reinforcing element connecting the welded ends and preventing any stress on the welded zone perpendicular to the welded ends.
- the invention consists of a tubular packaging body formed from a flexible film of a thickness e whose ends are welded end to end and covered by a plastic reinforcing element disposed on the inner surface of said tubular body and having a section defined by a width I and a height h, said tubular body being characterized by the fact that all the following conditions must be fulfilled:
- h is equal to or greater than e
- the ratio (le) / h 2 is between 1 and 10.
- the height h of the reinforcing element is at most equal to twice the thickness e of the film. More preferably, the following conditions must also be fulfilled:
- h is between 100 ⁇ and 500 ⁇
- e is between 100 ⁇ and 400 ⁇ .
- the height h of the reinforcing element is 1, 2 times equal to the thickness e of the film.
- I is between 1 and 3 mm.
- the film may be monolayer or multilayer.
- the invention is particularly advantageous when the multilayer film comprises layers which do not weld or are only partially welded, for example aluminum, EVOH, PA, PET, BOPP, paper or product layers. cellulose based.
- the invention is particularly advantageous when the layer forming the outer surface of the package does not weld or only partially bonds. This is the case for example multilayer films having outer layers of PET, BOPP, paper, PA.
- the reinforcing element added inside the packaging also appreciably improves the impermeability properties of the welded zone, for example the impermeability to oxygen, to aromas , with steam or with solvents.
- the reinforcing element may be multilayer and / or contain oxygen absorbers.
- the reinforcing element may comprise layers consisting of polyolefins, for example PE, PP and / or layers consisting of barrier polymers such as EVOH.
- Oxygen absorbers may be for example organic polymers which function by oxidation of iron, ascorbic acid or a cobalt catalyzed polyamide; these products are standard on the market. These elements react with oxygen to limit the migration of oxygen molecules inside the package.
- the reinforcing element contains additives for combating counterfeiting. These additives of microscopic or nanoscopic size do not modify the mechanical properties of the reinforcing element.
- additives are, for example, metal salts or derivatives of crosslinked melamine particles or powders of micrometric or nanometric size. These additives added in a very small quantity in the plastic material are generally sold in the form of masterbatch compounds and can be easily integrated into the manufacturing process of the reinforcement element 7. These products are marketed for example by the companies Micro trace, Polysecure or Phoenix plastics.
- the first method of producing the tubular packaging body according to the invention consists in forming the reinforcing element together with the butt-welding of the flexible film.
- a bead of plastic material is extruded and melt-laid on the ends of the flexible film; the heat energy contained in the bead is used to weld the bead to the flexible film and at least partially weld the ends of the flexible film against each other; and finally the bead is shaped by a tool adapted to form the reinforcing element according to the dimensions defined in the invention.
- a second method consists in welding on the ends of the flexible film a previously made plastic reinforcing element.
- the welding of the reinforcing element on the face of the flexible film forming the inner wall of the package is done in conjunction with the butt welding of the flexible film.
- the cord is preheated before the welding operation.
- the method is advantageously coupled to a bevel cut of the ends of the flexible film to facilitate butt welding.
- the beveled cut of the welded ends of the flexible film makes it possible to increase the surface in contact and the pressurization of the welded zone.
- a cutting angle of 45 ° with respect to the surface of the film is used.
- Figure 1 depicts the use of a welding reinforcing member within a package as described in the prior art.
- FIG. 2 illustrates the defect observed with the welding reinforcement elements described in the prior art.
- Figures 3 to 8 illustrate several embodiments of the invention.
- Figures 3 to 8 show the sectional view of the welded zone of the tubular packaging, the section being taken perpendicular to the axis of the tubular body.
- Figure 3 shows a first embodiment of the invention to use a reinforcement element of semi-oval section characterized by its width and height to strengthen the weld.
- Figure 4 shows the effect of the reinforcing element on the reinforcement of the welded zone and the displacement of stresses outside the welded zone.
- Figures 5 to 7 illustrate different sections of reinforcing elements for reinforcing the welded zone according to the invention.
- Figure 8 shows a variant of the invention also to constrain the welded zone in the opposite direction to the stress of the weld during use of the package.
- the invention consists of a novel flexible film butt welding configuration of adding a small plastic reinforcing element to the interior of the package connecting the welded ends of the flexible film; said reinforcing element having the effect of preventing any deformation of the welded zone perpendicular to the welded ends; and said reinforcing member having a geometry such that the flexibility of the welded zone in the tangential direction at the welded ends is not substantially changed.
- the reinforcing element has the effect of preventing modification of the radius of curvature of the package at the butt welded zone.
- Figures 3 to 8 show the sectional view of the welded zone of the tubular packaging, the section being taken perpendicular to the axis of the tubular body.
- FIG. 3 illustrates a first exemplary embodiment of the invention.
- the tubular body 1 is formed by butt welding the ends of a flexible film 2 of thickness e.
- the welded zone 2 is parallel to the axis of the tubular body.
- a reinforcing element of semi-oval section 7 connects the ends of the flexible film 2 and strengthens the welded zone 6.
- the invention is characterized in that the reinforcing element 7 prevents any local deformation of the welded zone 6 perpendicular to the welded ends while hardly changing the flexibility of the package parallel to the welded ends.
- the reinforcing element 7 prevents the variation of the radius of curvature which would have the effect of pulling the welded ends of the flexible film in tension.

- FIG. 6 an isosceles trapezoid-shaped section reinforcing element whose two sides are concave
- FIG. 7 a rectangle-shaped section reinforcement element.
- the geometries of the reinforcing element illustrated in FIGS. 5 and 6 make it possible to limit the concentration of stress that can appear in zones 8 and 9 when the multilayer film is folded strongly at the level of the weld.
- These sections of the reinforcing element 7 allow a more gradual transition of the deformation of the multilayer film in the zones 8 and 9 and avoid possible stress concentrations which would have the effect of degrading the multilayer film.
- FIG. 7 illustrates the section of a reinforcing element 7 which is easy to produce but which can create high concentrations of stresses in the zones 8 and 9 during the bending of the film 1 along the weld 6.
- FIG. 8 shows a variant of the invention consisting in prestressing the multilayer film by the reinforcing element of section 7 at the level of the weld 6.
