Definitions

  • the present invention relates to an installation for packaging products in containers, of the type comprising a conveyor above which are arranged a device for injecting liquefied gas into the containers and, downstream thereof relative to the direction movement of the conveyor, a container closure device.
  • Protection against oxygen may be necessary for various reasons, including the risk of degradation of the product by oxygen in the air, the possible attack of the product by a product of this reaction, depressurization (or the rise in pressure ) of the container (more or less flexible) of the container following reactions of the product with oxygen (for example in the case of products containing terpenes). This change in pressure distorts the packaging and leads to storage problems (curved bottles for example), aesthetics or adhesion of labels subsequently deposited.
  • the pressurization of the containers makes it possible to compensate for a depressurization of the containers during the cooling of hot packaged products, and / or to compensate for the permeation of gases through the wall of the containers, and it improves the mechanical strength of the containers during handling, reducing the wall thickness necessary for their realization.
  • - inerting by gas the containers pass through a tunnel, or hooded passage, with or without airlock, under maintained gas pressure, or under devices, (pipes, canes, nozzles ...) injecting the gas under consideration.
  • the gas used is generally nitrogen, carbon dioxide, or a mixture of the two. It is thus possible to obtain fairly low residual oxygen levels (up to approximately 3%, in certain cases), but it is not possible to generate or maintain a significant overpressure;
  • - inerting / pressurization by liquid the containers receive, before fitting the cap, a few drops of liquefied gas, which vaporize by expelling the air and creating the desired overpressure.
  • the present invention aims to provide an installation capable of generating and maintaining on the one hand a constant and adjustable overpressure, on the other hand a very low residual oxygen level, whatever the type of product added.
  • the subject of the invention is an installation of the aforementioned type, characterized in that it comprises a device for protecting the containers against ambient air extending between the injection device and the closure device.
  • the protection device forms a tunnel covering the conveyor, and the installation comprises means for injecting said gas in the gaseous state into the tunnel.
  • the protective device may in particular comprise, at least over part of its length, a flexible upper wall located a short distance from the opening of the containers.
  • the packaging installation shown in FIGS. 1 to 3 essentially comprises a conveyor 1 on which containers 2 run in a single row, a device 3 for injecting liquid nitrogen, a device 4 for closing the containers, and a protection tunnel 5.
  • the devices 3 and 4 are arranged directly above the conveyor, the device 4 being located downstream of the device 3 relative to the direction of travel of this conveyor; the tunnel 5 covers the conveyor between these two devices, from a location located a little downstream of the device 3 to a location located a little upstream of the device 4.
  • the containers 2, which are plastic bottles in this example after having received a determined quantity of a product 6, which can in particular be an organic liquid, pass successively under the device 3, through the tunnel 5 then under the device 4.
  • the liquid nitrogen injection device 3 can be any one of the various types of known devices, for example as described in the aforementioned patent EP 103 506. It is supplied with liquid nitrogen by a thermally insulated pipe 7 connected to the lower part of a tank 8 of liquid nitrogen.
  • the shutter device 4 is also conventional. It is used to fix by crimping a cap 9 on each bottle leaving the tunnel 5.
  • the tunnel 5, open at both ends, comprises a flexible wall 10 made of a material resistant to low temperatures, for example a sheet of "Mylar", held by a series of arches 11 which are themselves fixed on the fixed edges 12 ( Figures 2 and 3) of the conveyor 1.
  • These arches give the wall 10 a roughly constant cross section, for example rectangular as shown in Figure 3, with an upper wall 13 and two side walls 14 they also fixed to the edges 11.
  • two cables 15, threaded in longitudinal rows of holes 16 provided in the upper wall 13, include tensioning means (not shown) and make it possible to prevent the deflection of this wall 13 between the arches 11.
  • the wall 13 descends slightly from upstream to downstream.
  • Each ramp 17 is mounted in the tunnel 5, on either side of the bottles 2, and extend over the entire length of the tunnel.
  • Each ramp has a longitudinal slot 18 located approximately almost two thirds of the height of the bottles 2 and oriented at about 45 ° downwards.
  • Each ramp is supplied by a pipe 19 connected to the top of the liquid nitrogen tank 8 and passing through an orifice 20 in the corresponding side wall 14.
  • each bottle receives, directly on the product 6, a small determined quantity of liquid nitrogen.
  • This liquid gradually vaporizes during the passage in the tunnel 5, generating nitrogen gas which expels the air contained in the upper part of the bottles.
  • the bottles 2 are subjected to shocks or vibrations in the tunnel 5, by known means not shown, in order to break into multiple droplets the single drop of liquid nitrogen which forms on the product 6 under the effect of calefaction.
  • tunnel 5 The purpose of tunnel 5 is to prevent backscattering of the air in the bottles.
  • the upper wall 13 limits the gas passage section around the necks of the bottles and increases the speed of exit of the gases out of these necks, and the ramps 17 permanently inject nitrogen gas into the tunnel, this nitrogen gas licking bottles from top to bottom as shown in Figure 3.
  • the length of the tunnel is chosen so that the end of the vaporization of the liquid nitrogen occurs a little upstream of its exit.
  • the downward shape of the wall 13 makes it possible to generate an almost constant overpressure in the bottles 2 over the entire length of the tunnel, at least in the terminal part of it.
  • the upper part of the bottles thus contains nitrogen gas under a slight overpressure, which maintains an ascending current of nitrogen during the short time, of the order of a second, which separates the exit of a bottle from the tunnel from the moment it is provided with a stopper by the device 4.
  • the invention applies to the packaging of very diverse products, especially liquid or pasty, such as: non-carbonated drinks, pesticides, fungicides, phytosanitary products or liquid detergents, solvents and chemical or petroleum products, cosmetics and pharmaceuticals, etc. ..
  • the containers can be bottles, boxes etc ..., and be made of glass, metal, plastic, etc ...
