Definitions

  • the present invention relates to the sealing of containers in applications wherein vacuum can develop inside the containers and more particularly can mechanically deform the containers or wherein an overpressure can build up inside the containers and more particularly can mechanically deform the containers.
  • the invention is more especially useful for hermetically sealing containers in hot-fill applications, or for hermetically sealing containers that have been sterilized, notably by carrying out a pasteurization process or a retort process.
  • the invention relates to a novel venting closure that is suitable for sealing a container and avoiding pressures (vacuum pressures or overpressures) inside the container, and in particular pressures that could mechanically deform the container, and to a process for filling and sealing a container.
  • a container is filled with a commodity such as for example a liquid, while the commodity is at an elevated temperature.
  • a commodity such as for example a liquid
  • the temperature is typically between 68°C and 96°C, and is usually around 85°C.
  • the high temperature of the commodity also sterilizes the container at the time of filling.
  • the container is not completely filled, but the filling is generally performed in such a way to keep a headspace with air inside the container.
  • the container After being hot-filled, the container is capped and allowed to reside at generally the filling temperature for a few minutes and is then actively cooled prior to transferring to labeling, packaging, and shipping operations.
  • PET Polyethylene Terephthalate
  • Plastic hot-fill containers incorporating such deformable structures are for example described in the following publications: U.S. Patents 5,005,716 ; 5,503,283 ; 6,595,380 ; 6,896,147 ; 6,942,116 ; and 7,017,763 , and PCT application WO 2001/014759 .
  • a deformable structure to at least partially compensating the volume reduction that occurs after capping and during cooling of a hot-filled product is located in the base of the container. More particularly, in PCT application WO 2011/014759 , the movable container base includes a central push-up portion and is designed to move up to accommodate internal vacuum pressures.
  • Plastic hot-fill containers are also described for example in the following publications: European patent application EP 1 947 016 and U.S. Patents 5,222,615 ; 5,762,221 ; 6,044,996 ; 6,662,961 ; 6,830,158 .
  • a deformable portion to at least partially compensating the volume reduction that occurs after capping and during cooling of a hot-filled product, is located in the shoulder part of the container.
  • Plastic hot-fill containers are also described for example in the following publications : U.S. Patents 5,092,475 ; 5,141,121 ; 5,178,289 ; 5,303,834 ; 5,704,504 ; 6,585,125 ; 6,698,606 ; 5,392,937 ; 5,407,086 ; 5,598,941 ; 5,971,184 ; 6,554,146 ; 6,796,450 .
  • the deformable portions to at least partially compensating the volume reduction that occurs after capping and during cooling of a hot-filled product, are located in the sidewall of the main body of the container, and are commonly referred as vacuum panels. In this case, the volume compensation can be advantageously increased.
  • the hot filling process is acceptable for commodities having a high acid content, but is not generally acceptable for non-high acid content commodities.
  • non-high acid commodities pasteurization and retort are generally the preferred sterilization processes.
  • Pasteurization and retort are both processes for cooking or sterilizing the contents of a container after filling. Both processes include the heating of the contents of the container to a specified temperature, usually above approximately 70°C for a specified length of time (for example 20 - 60 minutes). Retort differs from pasteurization in that retort uses higher temperatures to sterilize the container and cook its contents. Retort also generally applies elevated air pressure externally to the container to counteract pressure inside the container.
  • One first solution to avoid the development of pressures (vacuum pressures or overpressure) inside a deformable container in hot-fill applications or in pasteurization and retort processes is to perform the sealing of the container in two sequential steps.
  • a closure cap is for example positioned onto the container, but the container is not hermetically sealed, and air from the outside can freely enter inside the container, thereby avoiding the development of internal vacuum during the cooling phase of the product or air can freely escape outside the container, thereby avoiding the development of internal overpressures during the heating phase of the product.
  • the container is hermetically sealed by the closure cap.
  • a major problem of these first and second solutions is that the air entering in the container during the cooling phase can transport contaminating agents, such as for example dust, bacteria and can detrimentally contaminate the product stored in the container.
  • a closure cap having a gas permeable vent with an integral sealing means that is externally activable by a nonmechanical means, to effect hermetic sealing of the container after filling and cooling.
  • the gas permeable vent is a non-fusible porous matrix or membrane and comprises a porous fusible material that can hermetically close the non-fusible porous matrix when it is melted, for example by using an electromagnetic induction source.
  • the sealing of the container is performed in two steps. In a first step, once the container is being filled with a hot product, the container is closed by the said closure cap.
  • the porous fusible material is activated, for example by means of an electromagnetic induction source, and is melted in such a way to hermetically seal the non-fusible porous matrix or membrane, thereby hermetically sealing the container.
  • An objective of the invention is to propose a novel technical solution for sealing a container in applications wherein pressures (vacuum pressures or overpressures) can develop inside the container and in particular can mechanically deform the container, which solution avoids the development of such internal pressures and also reduces the risk of contamination of the inside of the container, and which solution also avoids the use of a special equipment for heat-sealing a venting closure as disclosed in PCT application WO 2009/117328 .
  • Another objective of the invention is to propose a venting closure that can be easily recycled.
  • a first object of the invention is a venting closure as defined in claim 1.
  • Another object of the invention is the container and venting closure of claim 17
  • Another object of the invention is the process for filing and sealing a container as defined in claim 25.
  • a closure 1 A of the invention is fitted onto a standard neck finish 2 of a deformable container C comprising a top opening 20 (container mouth), like for example a bottle neck finish.
  • This top opening 20 of the neck finish 2 is knowingly used for filling the container with a product and/or for pouring the product outside the container.
  • the closure 1 is a cap screwed on the container neck finish 2.
  • the closure 1 could be snapped on the container neck finish 2.
  • the container can be made from any material that makes the container deformable at ambient temperature under an internal pressure (vacuum pressure or overpressure) generated inside the container C.
  • the container C can be for example any plastic container or any cardboard container. More particularly, the container is not made of glass.
  • the container can be for example a bottle-shaped container, a flask, a jar, a tube, a bag, a pouch.
  • the deformable container C can be rigid, semi rigid or flexible.
  • the container C may be either of a monolayer construction or a multilayer construction.
  • suitable thermoplastic materials which may be used, as a layer or part of one or more layers in either monolayer or multilayer containers, include polyesters, and in particular polyethylene terephtalate (PET), polyolefins (including but not limited to polypropylene(PP) and polyethylene (PE)), polyetheresters, polyesteramides, polyurethanes, polyimides, polyureas, polyamideimides, polyamides, polyacrylates, polyphenyleneoxide, phenoxy resins, epoxy resins, polystyrene (PS), polyvinyl (including but not limited to polyvinyl chloride (PVC), polylactic acid (PLA), polyethylene-furanoate (PEF), homo or copolymers thereof, or combinations thereof.

  • air A coming from the outside of the container C is passing necessarily through the porous venting medium 104 ( figure 1 ) and is filtered by the porous venting medium 104 before entering inside the container into contact with the product stored inside the container.
  • This incoming and filtered air advantageously avoids the development of vacuum pressures inside the container C while avoiding a contamination of the inside of the container and of the product.
  • air can advantageously escape outside the container by passing through the porous venting medium 104, thereby avoiding the development of an overpressure inside the container.
