Description
PACKAGING WITH BREATHABLE VALVE FOR PRODUCTS
PERISHABLE
1 . Field of technique
A gasket with a breathable valve is disclosed to prolong the green life of perishable products. The packaging consists of a flexible container (1) and a breathable valve assembly (2) that allows to control the concentration of oxygen, carbon dioxide, water vapor and ethylene in the internal atmosphere, at a desired value depending on the weight and the breathing speed of the product. The breathable valve assembly (2) comprises a ring (3) and a breathable plug (4) which is assembled to close the flexible container (1). Compared to the prior art, the disclosed packaging has the advantage of being able to be assembled without the need for a heat sealing technique and to increase the green life of perishable products, such as vegetables and fruits.
2. objective
The present invention relates to the packaging of perishable products, such as vegetables and fruits, in particular with the means to control the composition of the gases in the internal atmosphere and facilitate the closure, for example, packaging manual, without the need to use techniques automatic, such as heat sealing.
3. Description of the state of the art
Some perishable products, such as vegetables and fruits, continue their ripening and aging process after harvesting. During ripening and aging, the product exhibits a respiration process characterized by the absorption of oxygen and the release of carbon dioxide and ethylene. Additionally, the product exhibits moisture perspiration, decreasing its weight. The decrease in respiration and transpiration in the package is crucial to extend the green life of perishable products. Another problem associated with uncontrolled respiration is that of reaching a high concentration of carbon dioxide in the atmosphere inside the package, which affects the organoleptic properties of the perishable product.
Some alternatives for the control of respiration and transpiration of perishable products in packaging have been recorded in the state of the art. These technologies include the following: transport in refrigerated containers; hypobaric packing; containers with devices that remove ethylene; active packing that traps oxygen, carbon dioxide and ethylene; packing in modified atmosphere; coatings on cardboard; chemical or physical treatment directly on the product; and breathable packaging. Comparatively with the breathable packaging, the other technologies have some disadvantages, such as the possibility of damage by low temperatures in refrigerated options, high costs, consumer perception and difficulties in packaging operations.
One of the most used packaging for perishable products is the breathable packaging, due to the convenience in costs. The technologies of breathable packaging includes several possibilities among which are: high permeability films; macro and micro-perforated films; the permeable patches and windows; the valves and ventilation channels.
Macro and micro perforated films have been disclosed in several patents (US51301 52, US20051 80664, DE20200501 1737, GB1 106265, GB1 134667, GB2141688, and JP6199385). This alternative has some disadvantages, such as: the need to seal the mouth of the package, the product can block some of the perforations and the need for additional operations to manufacture the film or the bag.
Permeable patches and windows have been disclosed in the state of the art (US4842875, US4943440, US5045331, GB1071586, FR2686577 and CN 1 036539). The main disadvantages of this technology are: the need to seal the mouth of the packaging and the need for additional operations to manufacture the film or bag.
Ventilation channels have been disclosed in the state of the art (US2004131731, US2007257040, US20081 16098, WO2007008459, WO2010141467 and J P2002308293). The main disadvantages of this technology are: the need to seal the mouth of the package and the need for additional manufacturing operations of the bag.
Although some valves have been reported in the state of the art
(US3937396, US5996800, US20031 52296, WO2004108557, WO2004043191, EP0700839, JP1279073, JP1 1301743 and JP2006125559), all valves require sealing to the bag, as well as additional operations for manufacturing the bag.
The package of the present invention discloses a combination of a flexible container and a breathable valve, itself comprised of a ring and a breathable cap to prolong the green life of perishable products, such as vegetables and fruits. The packaging of the present invention provides the possibility of performing a mechanical assembly, either manual or automatic, without the need for heat sealing technologies; of not requiring additional operations in the manufacture of the bags; to be able to open and reopen in the ripening chambers; of being recyclable and of low cost. In addition to prolonging the green life of the product it is possible to increase the time of growth of the fruit or vegetable in the plant.
4. BRIEF DESCRIPTION OF THE INVENTION
The present invention provides a package with a breathable valve to prolong the green life of perishable products that exhibit post-harvest respiration, such as vegetables and fruits. The package comprises a flexible container and a valve assembly that is assembled in the mouth of the flexible package to create a controlled gaseous atmosphere inside the package. In turn, the valve assembly comprises a ring located outside the flexible container and a breathable cap located inside the flexible container.
flexible container; These two components can be assembled mechanically without the need for heat sealing technologies to close the mouth of the flexible container. The breathable cap has fixing means for joining both parts with the flexible container in the middle, which can be assembled by interference and pressure adjustments. The breathable cap can be a plastic cap with a plurality of microperforations or nanoperforations, or an annular section that allows the installation of a permeable membrane sandwiched between the ring, the flexible container and the breathable cap. The permeable membrane can be a cavitated, microperforated or nanoperforated film. The concentration of oxygen, water vapor, carbon dioxide and ethylene is controlled by the permeation of the breathable cap, the weight and breathing speed of the perishable product contained. The permeation of the breathable cap is controlled with the number and size of micro and nanoperforations, in the case of the plastic lid and the perforated micro and nano film; and with the permeability to gases in the case of cavitated film.

6. Detailed description of the invention :
The present invention provides a package provided with a breathable valve to prolong the green life of perishable products that exhibit respiration after harvesting, such as vegetables and fruits. With reference to the embodiment illustrated in figures 1 and 2, the package comprises a flexible container (1) characterized by the presence of at least one mouth, and at least one valve assembly (2) composed of two parts: a ring ( 3), which is located on the periphery and external surface of the mouth of the flexible container (1), and a breathable cap (4), which is mechanically coupled with the inside of the ring (3) in such a way that the material of the The mouth of the flexible container (1) is fixed between the breathable cap (4) and the ring (3).
The flexible container (1) is a flexible film, produced for example by casting, blown extrusion, flat film extrusion, co-extrusion or rolling. The polymer film is produced with a polymer preferably selected from the group comprising Polyethylene, Polypropylene, Polyethylene terephthalate, Polyamide, Polystyrene copolymers, Cellophane, Polylactic acid, Acetate.
of cellulose, thermoplastic starch and its derivatives, and mixtures thereof.
With reference to figures 3 and 4, the valve assembly (2) comprises two parts: the ring (3) and the breathable plug (4), which can be assembled mechanically without the need to use heat sealing technologies to close the mouth of the flexible container (1), nor does it require additional operations in the manufacture of the bag. The breathable cap (4) has fixing means for joining both of its parts to the flexible container (1) in such a way that the film forming the mouth of the container is fixed between the two parts of the valve. In the embodiment illustrated in Figures 3 and 4, a pressure adjustment (6) is used. Figures 3 and 4 also show a rectangular channel (7) in the breathable cap (4) for the demolding without moving elements of the parts to be assembled by pressure (6).
With reference to Figures 1, 2 and 5, in another embodiment of the present invention, the fixing means for joining both parts of the valve assembly (2) with the flexible container (1), is by interference of the ring (3). ) and breathable cap (4). In this sense, it is convenient that the breathable cap (4) have conical side walls to facilitate the assembly with the ring (3). Referring now to Figure 5, in a particular embodiment of the present invention, the interference assembly is produced between an extension (8) of the breathable cap (4) and the corresponding cavity in the ring (3). With reference to Figures 5 to 7, although the preferred embodiment is a ring (3) and a breathable cap (4) of circular shape, other forms are also
possible, for example polygonal or triangular shapes.
The ring (3) and breathable plug (4) of the valve assembly (2) can be produced by injection molding or by press molding, using a polymer preferably from the group comprising thermoplastic polyurethane, vulcanized thermoplastics, thermoplastic elastomers , Polyethylene, Polypropylene, Polyethylene terephthalate, Polyamide, Polystyrene copolymers, Polylactic acid, Cellulose acetate, Thermoplastic starch and its derivatives, and mixtures thereof. In a particular embodiment of the present invention, the ring (3) and breathable cap (4) of the valve assembly (2) are made of a material whose hardness must be less than that which produces a mark on the fruit or vegetable. For example, in the plantain hardness should be less than 80 Shore A in the case of banana, preferably less than 60 Shore A, to ensure that the banana does not suffer damage, nor is carved with the valve. For the same reason it is advantageous that the contours are rounded.
With reference to figures 1 to 7, in another embodiment, the breathable cap (4) can be a plastic cap characterized by a plurality of micro or nano perforations (5).
Referring now to Figure 8, another embodiment of the present invention uses an annular section (9) which allows the installation of a permeable membrane (10) interspersed between the ring (3), the flexible container (1) and the annular section ( 9). The permeable membrane (10) can be a cavitated film, a perforated micro or nano film. The cavitated film can be produced using a cavitating charge, such as
calcium carbonate. The microperforated film can be produced using for example mechanical, laser or electrostatic technology. The present invention can use any embodiment of the breathable cap (4) even with the permeable membrane (10) sandwiched between the ring (3) and the flexible container (1). The annular section (9) of this embodiment is mechanically coupled to the ring (3) and the mouth of the flexible container (1) to tension the permeable membrane (10).
The concentration of oxygen, water vapor, carbon dioxide and ethylene can be controlled by permeating the breathable cap (4), the weight and the respiration rate of perishable product content. The permeability of the breathable cap (4) is controlled by the number and size of the micro and nano perforations in the case of the plastic lid and the perforated micro and nano film, and with the permeability to gases in the case of the film cavitated

Breathable valve packaging increases green life, decreases weight loss and reduces the conversion of starch into carbohydrates (measured as brix degrees).
Example 3:
In this example, he compares the evolution of the concentration of oxygen and carbon dioxide at 1 3 ° C for two plastic lids with 1 1 and 18 perforations. The same flexible container, the same valve assembly and the same amount of bananas of example 1 were used. Referring to Figure 9, after 4 days the concentration of gases is regulated to a constant value that depends on the number of perforations.
Example 4:
An important characteristic of the breathable valve material is its hardness and its contours, so that it does not generate damage in the perishable product that is being packed. In this example, the effect of the hardness and contour of the packaging material with breathable valve in bananas is evaluated. The effect of 3.5 kg (approximately three bunches of green bananas) applied on the breathable valve and on the banana peel is evaluated. The use of a Shore A hardness of less than 80 and a valve with a rounded contour is essential to avoid skinning the banana peel.
