Definitions
- the present invention relates to a pouch, specifically for liquid or granular products.
- the invention relates to an inflatable pouch.
- the present invention also relates to a method of manufacturing said pouch.
- Pouches are well-known in the art. They are for example used to package liquid or granular products for food and medical use.
- a known pouch typically consists of two superimposed walls of flexible plastic material, such as polyethylene, bonded to each other, typically heat-sealed, at peripheral edges thereof, so as to form an internal space of the pouch, suitable for being filled with the product to be packaged.
- the pouch can be also provided with a closure spout.
- the pouch is not impervious to the transmission of contaminant agents, such as microorganisms, oxygen, other gases and water vapour, then the product packaged in the pouch can undergo a degradation by transmission through the walls.
- oxygen normally permeates the internal space along the sealed peripheral edges of the pouch.
- a gas more particularly, oxygen
- other contaminant agents which can pass through the pouch walls and degrade the product packaged therein might be considered in place or in combination with the aforementioned gas.
- aseptic and ultra clean pouches are available on the market. They are typically made of laminate materials, for example comprising one or more layers of polypropylene and a layer of aluminium or polyethylene with Deposited Silicon Oxide (PET-SiOx).
- laminate materials for example comprising one or more layers of polypropylene and a layer of aluminium or polyethylene with Deposited Silicon Oxide (PET-SiOx).
- the aseptic and ultra clean pouches are produced in aseptic and ultra clean filling systems.
- the aseptic filling systems provide commercial sterility, whereby no unwanted organisms will grow in the filled pouch, whereas the ultra clean filling reduces the presence of organisms to levels approaching zero, but are not designed to ensure zero contamination.
- EP 1 2 42 293 discloses a packaging container made of plastic material consisting of a flat hose, which is sealed at least on one side and forms a bag-shaped container.
- the flat hose is surrounded by two flat film sections, which overlap the edge regions.
- the hose has a filling opening and connection seams.
- US 5,588,532 discloses an inflatable package comprising a pair of overlying inner panels defining an item-receiving zone therebetween to have the object received therein, a pair of outer panels each overlying a respective one of the inner panels to form an inflatable chamber therebetween and inflating means for at least partially inflating the inflatable chamber with a filler medium.
- US 4,872,558 discloses a packaging system including an outer bag defining a sealed chamber therein, an inner bag defining a pocket adapted to retain an article therein and means for filling the chamber with a filling medium to substantially encapsulate and support the inner bag and article within the outer bag.
- US 4 454 945 discloses a pouch made from two tubular films.
- the superimposed walls typically heat-sealed, they can delaminate, i. e. the walls can partially separate from each other. As a result, ruptures or micro-perforations can generate at the sealed edges, thus causing the oxygen to enter the pouch, so deteriorating the product present therein.
- the laminate materials are thick, this considerably increasing the manufacturing and shipment costs of the pouch, as well as the environmental impact of the pouch in that more plastic is needed for producing it and needed to be disposed at the end of its lifecycle.
- the pouch when the pouch is produced in aseptic or ultra clean filling systems, it is not possible to use a printed film, because the ink is dissolved when the film enters a chemical decontamination area, e.g. it is dipped in a tank containing for example a hydrogen peroxide decontaminating liquid. In order to avoid the ink to be dissolved, expensive trap printing systems are used, thus further increasing the production costs of the pouch.
- the present invention provides a pouch, particularly for liquid or granular products, which is suitable for increasing the gas-barrier effect at the sealed edges thereof, meanwhile making it possible to reduce the material thickness and, consequently, the manufacturing and shipment costs of the pouch.
- the present pouch can be easily printed avoiding any problem of ink discoloration.
- the present invention in a first aspect thereof, relates to a pouch comprising:- an inner pouch comprising a bottom surface and opposite side walls extending upwardly from the bottom surface, said opposite side walls being associated to each other along at least one peripheral edge thereof, thereby delimiting a product-filling area; characterized in that the pouch comprises a pair of outer films, each overlying a respective one of said opposite side walls of the inner pouch, said outer films being associated to each other through a first seal at said at least one peripheral edge of the inner pouch; and in that the outer films are further associated to each other through a second seal spaced apart from the first seal with respect to the product-filling area, thereby delimiting between said first seal and second seal at least one inflatable chamber filled with an inert gas.
- the pouch of the present invention has enhanced properties in terms of gas-barrier at the sealed edges thereof,
- gas-barrier is meant the capability to limit to a certain extent the passage of contaminant agent.
- the desired gas-barrier properties are achieved by a layer, seal or structure when the OTR (Oxygen Transmission Rate) evaluated at 23°C and 0% R.H. according to ASTM D-3985 is lower than 500 cm 3 /m 2 •day•atm, preferably lower than 100 cm 3 /m 2 ⁇ day ⁇ atm, more preferably lower that 50 cm 3 /m 2 ⁇ day ⁇ atm.
- the outer films are directly associated, one inflatable chamber being defined between the outer films.
- the outer films are sealed at the at least one peripheral edge of the inner pouch, one inflatable chamber being defined between each outer film and the at least one peripheral edge.

- PET-SiOx Deposited Silicon Oxide
- At least one outer film has a printed surface.
- the outer printed film needs not to undergo any decontamination process but is applied externally to the aseptic inner pouch. This advantageously allows to have a printed pouch and avoids expensive trap printing systems to be used when the pouch is produced in aseptic or ultra clean filling systems, thus reducing the pouch production costs.

Description
- The present invention relates to a pouch, specifically for liquid or granular products. In particular, the invention relates to an inflatable pouch.
- The present invention also relates to a method of manufacturing said pouch.
- Pouches are well-known in the art. They are for example used to package liquid or granular products for food and medical use.
- A known pouch typically consists of two superimposed walls of flexible plastic material, such as polyethylene, bonded to each other, typically heat-sealed, at peripheral edges thereof, so as to form an internal space of the pouch, suitable for being filled with the product to be packaged. The pouch can be also provided with a closure spout.
- With specific reference to products having high degradability, such as food products, there is a growing demand for extending the shelf life of these products when packaged.
- If the pouch is not impervious to the transmission of contaminant agents, such as microorganisms, oxygen, other gases and water vapour, then the product packaged in the pouch can undergo a degradation by transmission through the walls. In particular, oxygen normally permeates the internal space along the sealed peripheral edges of the pouch.
- Throughout the following description and the annexed claims, by "sealing" or "seal" a hermetical junction of the pouch walls, which can be made by means of heat-sealing or ultrasound sealing, or with other known methods is meant.
- Throughout the following description and the annexed claims, reference will be specifically made to a gas (more particularly, oxygen) as a contaminant agent, while other contaminant agents which can pass through the pouch walls and degrade the product packaged therein might be considered in place or in combination with the aforementioned gas.
- In order to extend the shelf life of the packaged product, so called aseptic and ultra clean pouches are available on the market. They are typically made of laminate materials, for example comprising one or more layers of polypropylene and a layer of aluminium or polyethylene with Deposited Silicon Oxide (PET-SiOx).
- The aseptic and ultra clean pouches are produced in aseptic and ultra clean filling systems.
- In particular, the aseptic filling systems provide commercial sterility, whereby no unwanted organisms will grow in the filled pouch, whereas the ultra clean filling reduces the presence of organisms to levels approaching zero, but are not designed to ensure zero contamination.

EP 1 2 42 293 -
US 5,588,532 discloses an inflatable package comprising a pair of overlying inner panels defining an item-receiving zone therebetween to have the object received therein, a pair of outer panels each overlying a respective one of the inner panels to form an inflatable chamber therebetween and inflating means for at least partially inflating the inflatable chamber with a filler medium. -
US 4,872,558 discloses a packaging system including an outer bag defining a sealed chamber therein, an inner bag defining a pocket adapted to retain an article therein and means for filling the chamber with a filling medium to substantially encapsulate and support the inner bag and article within the outer bag. -
US 4 454 945 discloses a pouch made from two tubular films. - The Applicant has found that, although the laminate materials of the prior art are known as having high gas-barrier properties, pouches made of these materials have some drawbacks.
- Firstly, being the superimposed walls typically heat-sealed, they can delaminate, i. e. the walls can partially separate from each other. As a result, ruptures or micro-perforations can generate at the sealed edges, thus causing the oxygen to enter the pouch, so deteriorating the product present therein. Further, the laminate materials are thick, this considerably increasing the manufacturing and shipment costs of the pouch, as well as the environmental impact of the pouch in that more plastic is needed for producing it and needed to be disposed at the end of its lifecycle.
- Furthermore, when the pouch is produced in aseptic or ultra clean filling systems, it is not possible to use a printed film, because the ink is dissolved when the film enters a chemical decontamination area, e.g. it is dipped in a tank containing for example a hydrogen peroxide decontaminating liquid. In order to avoid the ink to be dissolved, expensive trap printing systems are used, thus further increasing the production costs of the pouch.
- The present invention provides a pouch, particularly for liquid or granular products, which is suitable for increasing the gas-barrier effect at the sealed edges thereof, meanwhile making it possible to reduce the material thickness and, consequently, the manufacturing and shipment costs of the pouch. In addition the present pouch can be easily printed avoiding any problem of ink discoloration.
- The present invention, in a first aspect thereof, relates to a pouch comprising:- an inner pouch comprising a bottom surface and opposite side walls extending upwardly from the bottom surface, said opposite side walls being associated to each other along at least one peripheral edge thereof, thereby delimiting a product-filling area; characterized in that the pouch comprises a pair of outer films, each overlying a respective one of said opposite side walls of the inner pouch, said outer films being associated to each other through a first seal at said at least one peripheral edge of the inner pouch; and in that the outer films are further associated to each other through a second seal spaced apart from the first seal with respect to the product-filling area, thereby delimiting between said first seal and second seal at least one inflatable chamber filled with an inert gas.
- The Applicant has surprisingly found that, owing to the provision of the inflatable chamber/s filled with an inert gas formed by the outer films, the pouch of the present invention has enhanced properties in terms of gas-barrier at the sealed edges thereof,
- with respect to the conventional pouches. This advantageously allows the use of thinner and cheaper materials for the inner pouch as well as for the outer films, thus reducing the manufacturing and shipment costs of the pouch.
- Throughout the following description and the annexed claims, by "associated" and "associating" a direct association between the outer films or an association between the outer films with the interposition of the associated side walls of the inner pouch is meant.
- Throughout the following description and the annexed claims, by "gas-barrier" is meant the capability to limit to a certain extent the passage of contaminant agent. With specific reference to oxygen, the desired gas-barrier properties are achieved by a layer, seal or structure when the OTR (Oxygen Transmission Rate) evaluated at 23°C and 0% R.H. according to ASTM D-3985 is lower than 500 cm3/m2•day•atm, preferably lower than 100 cm3/m2·day·atm, more preferably lower that 50 cm3/m2·day·atm.
- In a preferred embodiment, at the second seal, the outer films are directly associated, one inflatable chamber being defined between the outer films.
- In a further preferred embodiment, at the second seal, the outer films are sealed at the at least one peripheral edge of the inner pouch, one inflatable chamber being defined between each outer film and the at least one peripheral edge.
- Preferably, each of the outer film is sealed around the perimeter of a respective side wall of the inner pouch. This advantageously ensures a better matching between the inner pouch and the outer walls.
- Preferably, the inert gas filling the at least one inflatable chamber is nitrogen. This advantageously increases the gas-barrier properties of the pouch. However, different inert gases can be used.
- In a preferred embodiment, the inner pouch is made of a flexible plastic material, such as polyethylene.
- Preferably, the inner pouch is made of a material with gas-barrier properties, such as a mono or multilayer film or laminate comprising one or more layers of gas-barrier resins, such as polypropylene, ethylvinyl alcohol, polyvinylidenchloride, optionally including one or more layers of non plastic material, such as aluminium or polyethylene with Deposited Silicon Oxide (PET-SiOx). This additional material advantageously further increases the gas-barrier properties of the pouch, particularly in the event of an aseptic pouch.
- In a preferred embodiment, the outer films are made of a flexible plastic material, such as polyethylene.
- Preferably, the outer films are made of a material with gas-barrier properties, such as a mono or multilayer film or laminate comprising one or more layers of gas-barrier resins, such as polypropylene or others, optionally including one or more layers of non plastic material, such as aluminium or polyethylene with Deposited Silicon Oxide (PET-SiOx). This additional material advantageously further increases the gas-barrier properties of the pouch, particularly in the event of an aseptic pouch.
- Preferably, at least one outer film has a printed surface. The outer printed film needs not to undergo any decontamination process but is applied externally to the aseptic inner pouch. This advantageously allows to have a printed pouch and avoids expensive trap printing systems to be used when the pouch is produced in aseptic or ultra clean filling systems, thus reducing the pouch production costs.
- In a second aspect thereof, the present invention relates to a method of manufacturing a pouch comprising:
- providing an inner pouch, comprising a bottom surface and opposite side walls extending upwardly from the bottom surface, the opposite side walls being associated to each other along at least one peripheral edge thereof, thereby delimiting a product-filling area;
- feeding a pair of outer films, each of said outer films overlying a respective side wall of the inner pouch;
- associating the outer films to each other through a first seal at said at least one peripheral edge of the inner pouch;
- associating the outer films to each other through a second seal spaced apart from said first seal with respect to the product-filling area, thereby delimiting between said first seal and second seal at least one inflatable chamber ;
- inflating the at least one inflatable chamber with an inert gas; and
- sealing said at least one inflated chamber (34).
- In a preferred embodiment of the method, associating the outer films through a second seal comprises directly associating the outer film, one inflatable chamber being defined between the outer films.
- In a further preferred embodiment of the method, associating the outer films through a second seal comprises sealing the outer films to said at least one peripheral edge of the inner pouch, one inflatable chamber being defined between each outer film and said at least one peripheral edge.
- In a preferred embodiment of the method, a plurality of inner pouches are provided, said plurality of inner pouches being aligned along a feeding direction, before feeding said pair of outer films.
- Preferably, said plurality of inner pouches (20) are connected to each other at the peripheral edge.
- Preferably, associating the outer films to the inner pouch comprises sealing each outer films around the perimeter of a respective side wall of the inner pouch. This advantageously ensures a better matching between the inner pouch and the outer walls.
- Preferably, associating the outer films to each other through a second seal comprises associating the outer film through a weakening line (L). This advantageously allows a desired number of pouches to be grouped without providing expensive cardboard boxes. Moreover, owing to the connection weakening lines, the grouped pouches can be easily separated by an user.
- In a third aspect, thereof, the present invention relates to a set of pouches, each pouch being of the type discussed above, wherein at the outer films said pouches are associated to each other through respective weakening lines.
