Definitions

  • EP 0 011 911 A shows a chemiluminescent lighting device according to the preamble of claim 1.
  • the devices proposed comprise two chambers respectively containing the first liquid, said oxalate solution and the second liquid, called activator solution. These rooms are separated by a wall that can be broken by the user or have a removable portion. This wall must also be an excellent barrier to gases because the oxalate solution is very sensitive to any contamination from the outside, or the activator.
  • the oxalate solution is enclosed in a breakable glass ampoule. Unfortunately it is not possible to manufacture continuously, starting from rolls of material, elements comprising glass ampoules. In addition, they are expensive.
  • the present invention relates to an element capable of such continuous production, so very economical, especially since the constituent materials are very cheap.
  • the element also has the advantage of being flat, that of being particularly light, and has other auxiliary advantages which will appear in the following discussion.
  • the invention provides a chemiluminescent lighting element comprising at least two chambers respectively filled with an oxalate solution and an activating solution.
  • the oxalate solution is in a sealed pouch of aluminum foil lined on the inside of a polymer, said pouch forming a first chamber.
  • This pouch is itself enclosed in a larger waterproof pouch of translucent polymeric film, forming a second chamber, which also contains the liquid activator.
  • the element according to the invention therefore consists essentially of an aluminum film pouch containing the oxalate solution, disposed inside a translucent plastic film pouch also containing the activating solution.
  • an absorbent felt and a steel ball, or other grain of hard material whose role is to disembowel the aluminum pouch at the time of use, under the effect of the manipulation of the user.
  • the inner pocket 1 consists of two aluminum films 2 and 3 sealed together along a rectangular periphery 4 in FIGS. 1 and 2 and circular in figs. 3 and 4. It contains the solution of liquid oxalate, the level of which is shown in 5.
  • the outer pouch 6 consists of two films 7 and 8 made of translucent flexible polymer, preferably polyolefin, eg polyethylene or polypropylene, sealed together according to a periphery 9, rectangular in FIGS. 1 and 2 and circular in figs. 3 and 4. It contains the activator liquid whose level is represented in 10.
  • the device optionally comprises a ball 11 of steel or a grain of hard material on which the user will support to perforate the aluminum pouch and thus cause mixing. It is also conceivable to dispense with this ball or grain and burst the pouch by pressure. In this case it is good to provide a weakened resistance zone, for example a weld line.
  • Each of the two aluminum films is lined, by coating, lamination or any other technique, with a layer of polymeric varnish on that of their surfaces which is intended to come face to face.
  • This layer of varnish preferably based on a modified polypropylene or not is intended to ensure the adhesion of the two films to one another during the sealing of their periphery by thermal action. This layer is not shown in the figure for reasons of clarity.
  • This polymeric layer besides the adhesion, also plays the role of ensuring good compatibility between the aluminum material and the oxalate solution, which is very delicate and sensitive to contamination, and is compatible only with very few materials.
  • This layer is very thin so as not to strengthen the mechanical strength of the aluminum film, intended to break.
  • the device also comprises, optionally, a felt 12 (succession of small crosses in the figures) of nonwoven material whose fibers are preferably made of the same polymer as the films of the outer pocket. It will be trapped during peripheral thermal sealing between the two films. When storing the element before use, this felt will have time to absorb all the activating liquid and distribute it evenly throughout the pouch. This will result in a nice uniformity of light, after the release of the oxalate liquid, because the two liquids are eager to diffuse into each other in a short time.
  • the activator liquid level, shown at 10 in FIG. 2 is the one we have at the moment of filling, afterwards it is absorbed in the felt as mentioned above.
  • the aluminum pouch remains in place and plays the role of reflector; indeed, all the light emission is on the same side of the aluminum pouch namely the one that was disemboweled. There is almost no liquid from the other side of the aluminum pouch. This intense directional emission is undeniably an advantage over the prior art in the field.
  • peripheral sealing may affect any other form and in particular, for advertising purposes, represent the shape of a brand logo.
  • the machine can be of vertical type, as the figs suggest. 1 and 2, or horizontal type, as suggested in figs. 3 and 4. Stamping is easier in a horizontal machine, and can be limited to the bottom film.
  • the aluminum films have been coated or laminated with the polymeric varnish referred to above, during a preliminary operation, also carried out continuously by known means.
  • a second machine also of the "fill and seal” type, receives sequentially and synchronously with the previous one, the aluminum bags already filled and sealed, and seals together the two flexible plastic films and the felt, if provided. all three running continuously from their storage rollers. Before sealing a dose of activator liquid is introduced, as well as the ball.
  • Finished pockets come out at the bottom of the machine in a chain or sausage, and can be delivered as is to the user if he is interested in lines of light, novelty likely to meet the desires of the forces of the order or army for example.
  • said film was coated on its full width, ie 600 mm, with a polypropylene dispersion and treated in a tunnel oven.
  • the residual thickness deposited after curing is 6 micrometers.
  • the oxalate solution consists of a dibutyl phthalate solvent in which, per liter, are dissolved 120 g of oxalate CPO and 1.5 g of DPEA dye. These components are well known in the art in the field of chemiluminescent elements.
  • the ball is a rolling ball, third choice, with a diameter of 4.5 mm.
  • the outer cover films are polypropylene-polyethylene without slip agent in the formulation, 0.25 m rolls 40 mm wide, length 300 m. They are presented in ribbon width 45 mm, thickness 0.25 mm, in rolls of 300 meters.
  • the doses of oxalate and activator are 1.7 and 0.7 ml, respectively.
  • the seals are made using jaws or anvils in the shape of a rounded corner rectangle, with an effective sealing width of 2 mm.
  • the heat energy of the seals is provided either by electrical resistors or via an ultrasound generator.
  • the felt is a non-woven "spunbond" of polypropylene and polyethylene fibers, of 120 g per square meter.
  • the finished pieces separated by an automatic timed knife, measure 45 x 70 mm and weigh 4 g.
  • the procedure is as in Example 1 but using a machine of the horizontal type.
  • the stamping of the lower aluminum film is operated by lowering a punch before any sealing; then the removal of the liquid is carried out using a removable needle, then sealing between the two aluminum films is operated at once on the entire periphery.
  • the aluminum strips feeding the machine have a width of 41 mm and those of flexible plastic a width of 65 mm.
  • the amounts of oxalate solution and activating solution are 2.2 and 1 ml, respectively.
  • the finished parts have a diameter of 59 mm and weigh 5 g.
