  • the present invention relates to a device for the packaging and distribution of pasty or liquid products in the form of a gel or emulsion such as, for example, cosmetic or pharmaceutical products.
  • a gel or emulsion such as, for example, cosmetic or pharmaceutical products.
  • tubes or jars are used.
  • the drawbacks linked to the use of plastic tubes reside in the fact that once opened, the elasticity of the plastic allows air to be drawn back inside the tube which, after each expulsion of a dose of product , presents problems of oxidation or contamination of the contents.
  • Aluminum tubes do not have this drawback, but their deformability makes them unsightly and impractical after a few uses.
  • the present invention relates to a device for the packaging and distribution of pasty or liquid products which overcomes the aforementioned drawbacks and is distinguished by the characteristics listed in claim 1.
  • FIG. 1 The distribution and packaging device or packaging according to the invention as illustrated in FIG. 1 comprises a rigid box of rectangular shape, this box is pierced with a channel terminated by an expulsion orifice 2 on one of its faces.

  • the head of the body 28 sinks into the housing, the cutout 29, allowing the product to be expelled.
  • FIG 10 shows a fourth variant of the packaging according to the first embodiment of the invention in which two different products are present in the housing and mix at the time of expulsion.
  • the housing 1 comprises a primary chamber separated longitudinally into two half-chambers 30.30 'by a watertight partition 31, each of these half-chambers 30.30' comprises a free primary piston 32.32 ' fitted with a 33.33 'gasket.
  • a spring 34.34 ' is introduced between the bottom of the housing and the primary piston 32.32' of each of the two half-chambers 30.30 'so that the products contained in each of the upper parts of said half-chambers 30.30 'are under pressure.

  • the packaging does not deform and enjoys aesthetic qualities far superior to those of deformable tubes.
  • the use of the packaging is extremely simple and can be used with one hand which is not the case for tubes.
  • the product can be used in its entirety which is not easy when dealing with plastic tubes.
  • the external shape as well as the materials used for the manufacture of the packaging are adaptable to the storage constraints of transport and compatibility with the product. Finally, it is possible to simultaneously distribute doses of different products, in a proportion determined by the actuation of a single pusher.

  • This second non-return valve 59 is sandwiched between the front face of the main piston 56 and a washer 59a of which the hole is of a dimension corresponding to the passage of the valve 59.
  • the washer 59a and the valve 59 are applied against the face of the piston 56 by the spring 57.
  • This chamber 58 is connected by a channel 60 to an annular chamber 61 opening out on the periphery of the main piston. Seals are provided between the main piston 56 and the housing 50 near the front end of the piston and on each side of the annular chamber 61. These seals may have come from a molding piece with the piston 56.
  • the main piston 56 also has a blind central bore 62, having a shoulder, opening into the chamber 58.

  • the chamber 51 containing the product to be packaged and dispensed is closed towards the bottom of the case 50 by a movable bottom 66 provided with sealing lips rubbing against the case 50 and sliding freely in said chamber 51.
  • the main piston 56 When the user releases the plunger 65, the main piston 56 returns to the rest position (fig. 11) under the action of the spring 57. In doing so, the non-return valve 59 closes preventing any call for air by the outlet 55 while the non-return valve 53 opens and the product from the chamber 51 is vacuum drawn through the channel 52 into the end of the bore 54. End of return stroke of the main piston 56, the outlet orifice 55 is again closed. The movable bottom 66 rises in the chamber 51 under the effect of the vacuum created, thus avoiding any contact of the product with the air.
  • this mechanism is very simple, requires few parts and is easy to manufacture, the parts can either be easily machined, injected or molded.
  • the housing 50 has two chambers 51, 51a, intended to receive two different products, one pasty and the other liquid for example.
  • the mechanism for dispensing and metering the product contained in the chamber 51 of the housing is identical to that described in relation to FIGS. 11 to 13.
  • the mechanism for dispensing and metering the product contained in the chamber 51 a may include a check valve. non-return 67 located in the top of the chamber 51 a which has a hole 68 opening into the bore 54. In a variant, this non-return valve or valve 67 can be omitted.

  • the annular chamber 69 is no longer in connection with the outlet orifice 70 and the hole 68, the expulsion of the second product is stopped.
  • the displacement of the bottom 66 of the chamber 51 is used, taking place by vacuum to cause a corresponding displacement of the bottom 66a of the chamber 51 a. In this way, it is ensured that the two chambers 51 and 51 a are empty simultaneously.
  • the device is similar to that described with reference to Figure 14, but the second chamber 51a is entirely surrounded by the chamber 51 which has a hollow cylindrical shape.
