Definitions

  • the present invention relates to an improvement of the viscous substance dispensing container, as described and represented in French patent application No. 87 10053 filed on July 16, 1987 and published on January 20, 1989 under No. 2618127, which corresponds to European patent application filed on July 15, 1988 under No. 88401847.4.
  • the container described in this prior document comprises, as shown in FIG. 1 attached, a container body 1 provided with a reservoir 2 containing the substance to be dispensed and with a dispensing head 3 capable of being controlled upon opening or closing, the reservoir 2 being made of flexible material and the container further comprising pressure means 20, 23 making it possible to exert permanent pressure on the reservoir 2, in the presence of substance, in order to allow the distribution of the substance on single command when opening the dispensing head 3.
  • the improvement, according to the present invention, in the viscous substance distributor container according to French patent application No. 87 10053 filed on July 16, 1987 is remarkable in that the elastic means, bearing on the internal wall of the container body, include first and second elastic blades forming a spring between the internal faces of which the reservoir made of flexible material is placed and external return means acting on the external face of the springs.
  • the container according to the invention finds application in the distribution of creamy substances, either of high viscosity, conditioned under a pressure of 800 g / cm2, or of more fluid substances such as emulsions. .
  • the viscous substance dispensing container to which the invention applies comprises a container body 1, provided with a reservoir 2 containing the viscous substance to be dispensed.
  • the viscous substance dispensing container also comprises a dispensing head 3, capable of being controlled on opening or closing, in order to ensure the distribution of the aforementioned substance or its storage in the container.
  • the tank denoted 2 is made of flexible material, and means denoted 20, 23 designated by pressure means, make it possible to exert on the reservoir 2, in the presence of substance, a permanent pressure.
  • the aforementioned pressure means associated with the flexible material reservoir allow, on a single command when the dispensing head 3 is opened, the distribution of the viscous substance to be dispensed.
  • the tank 2 is advantageously constituted by a flexible elastic material constituting the wall or walls of the tank. These walls during the loading of viscous substance to be dispensed are put under mechanical tension, and the pressure means 20 are in this case, constituted in a nonlimiting manner by the elastic tension of the walls.
  • the elastic means 23, bearing on the internal wall of the container body 1, comprise a first 230 and a second 231 elastic blades forming a spring between the internal faces of which the reservoir 2 made of flexible material is placed.
  • means 2400 play the role of external return means acting on the external face of the springs.
  • FIG. 2a shows the first 230 and the second 231 elastic blades surrounding the reservoir 2 made of flexible material, when the latter is completely empty.
  • the external return means are advantageously constituted by an elastic sheath 2400, which is attached to the external face of the elastic blades 230 and 231.
  • the elastic sheath 2400 is stretched over the elastic blades 230, 231 when the reservoir 2 made of elastic material is empty, the two elastic blades 230, 231 have a minimum spacing.
  • the sheath is deformed transversely so as to have a dimension d elongation greater than the size of the blades 230 and 231, the subassembly consisting of the elastic blades 230, 231 and the reservoir 2 made of elastic material then being introduced into the expanded sheath.
  • the sheath is released and the latter comes to adapt directly to the elastic blades 230, 231, on the external wall of the latter.
  • the elastic sheath 2400 can be formed by a cylindrical rubber sleeve whose diameter, in the absence of deformation, is less than the diameter of the container body 1.
  • a rubber sleeve of medium quality such as a synthetic rubber sleeve since, of course, the viscous substance to be dispensed does not come into contact with the latter.
  • FIGS. 2a and 2b has the advantage of isolating the elastic blades 230, 231 made of steel from the contact of the container body 1, this contact having to be notably avoided when the container body 1 is made of aluminum, in order to avoid interactions by electropositivity between aluminum and steel.
  • the embodiment, as shown in FIGS. 2a and 2b, is thus very economical insofar as it makes it possible to provide for the use of elastic blades 230, 231 of small thickness, which makes it possible to reduce the manufacturing costs as a result. .
  • the rendering power of the viscous substance is thus linked, not only to the elasticity of the springs and their mechanical quality, but also to that of the sleeve 2400.
  • the rendering power of the viscous substance can be adjusted by the choice of the thickness of the elastic blades 230, 231, as well as the elasticity and the tension of the sheath 2400.
  • the embodiment shown in FIGS. 2a and 2b is particularly suitable for the distribution of emulsions of the viscous substance in the form of milk, such as toilet milk or even medicinal products, such as biafine, distributed by Laboratoires MEDIX in France and by its representatives.
  • a particularly efficient viscous substance dispensing container has thus been described in so far as an action external to the spring or elastic blades finally makes it possible, depending on the application considered, to modulate the dispensing power of the viscous substance considered.
