Definitions

  • the present invention relates to a dispenser for liquid or pasty products consisting of a deformable container hermetically sealed by a valve.
  • the elasticity of the container (in the sense of a fully reversible deformability) is also used to pressurize the product to be dispensed.
  • German patent DE-A-1 136 600 describes a bottle which is produced in an original configuration corresponding inter alia to a round shape. It is then filled while it is imposed, in particular by means mechanical, another configuration therefore leading to a smaller interior volume. After its hermetic closure, it tends to resume its original configuration so that an empty space is created which can then fill with carbon dioxide from the product.
  • the document also provides for an original configuration far from the round shape, the filling configuration being on the contrary closer to the round shape and therefore of greater volume.
  • the present invention retains the idea of a deformation imposed beforehand on an elastic container to pressurize the product contained inside the container while it seeks to return to its original configuration. It aims to find a structure of the container which lends itself particularly well to the transition from the original configuration to the configuration of larger volume by means of simple mechanical means while guaranteeing both easy manufacture and use.
  • a device for dispensing a pasty or liquid product comprising a container adapted to be mechanically deformed between an original configuration and a configuration of larger volume so that after it is filled with said product in the configuration of large volume, then its hermetic closure by a valve, the container tends to resume its original configuration and thus pressurize the product to be dispensed, characterized in that said container has two flexible faces connected together by a reinforced fold so that the faces container can move relative to each other, allowing passage from one configuration to another, and in that a distribution valve without air intake hermetically seals said distributor.
  • the faces of said container are in particular arranged so that the transition from the original configuration to the configuration of larger volume is obtained by introducing the container into a recess of a non-deformable part which constitutes the simple mechanical means sought after.
  • said container is a flat tube, said fold connecting the two flexible faces forming two sides, a bottom as well as corners of said flat tube, said flat tube further comprising a neck consisting of a rigid base surmounted by a neck.
  • a neck consisting of a rigid base surmounted by a neck.
  • an envelope comprising said faces, said sides, said bottom and said corners is welded to said base of said neck.
  • said corners of said flat tube are rounded to facilitate the introduction of said tube into said recess of said non-deformable part constituting said mechanical means.
  • said recess of said non-deformable part constituting said mechanical means is preferably a cylinder of elliptical section, the long side of said elliptical section being less than the distance separating said sides of said tube when said tube is at rest.
  • said container is a cylindrical bottle having an elongated neck, an ovoid body and a bottom, the reinforced fold connecting the two faces to form with them said ovoid body, said neck and said bottom being rigid.
  • said recess of said non-deformable part constituting said mechanical means is advantageously a cylinder of circular section, the diameter of said section being less than the diameter of said edge of said bottle when said bottle is at rest.
  • said container It is particularly easy to produce said container from molded plastic. Furthermore, said valve finds a clear advantage in being a precompression pump.
  • the dispenser of the invention does not require that the product is introduced therein under pressure.
  • the filling is effected at atmospheric pressure, which considerably simplifies this operation as well as that of crimping the valve.
  • the product remains at all times sheltered from air and therefore does not risk deteriorating by oxidation or contamination. This absence of air also avoids the need for a dip tube since the interior of the container contains only product to be dispensed.
  • the emission of the product can be caused in any position of the dispenser relative to the vertical.
  • the very structure of the present dispensing device is particularly interesting. It indeed comprises two flexible faces connected together by a reinforced fold. The latter can therefore act as a hinge and allow the displacement of the faces relative to each other. The latter are in particular able to move away from one another so that the capacity of the container increases.
  • a clever arrangement of the faces and of the fold is found which allows the hinges to be played with very simple mechanical means. It is, for example, a non-deformable part comprising a recess. Provided that its size is adapted to that of the dispensing device, the introduction of the latter into the recess has the effect of exerting pressure on the fold. It follows the separation of the flexible faces by their flexion according to a buckling mechanism.
  • Figures 1 to 4 it is a flat tube 1.
  • the front view of Figure 1 shows, thanks to a partial longitudinal section along the plane II-II of Figure 2, that it consists of an elongated envelope and a neck.
  • the neck also specified by the top view of FIG. 3, comprises a base 16 of elliptical shape surmounted by a cylindrical neck 17. It is preferably molded in one piece from a fairly rigid plastic material.
  • the envelope is on the contrary molded in a flexible material, advantageously polyethylene or polypropylene. It is welded at its upper edge 14 to the base 16 of the neck. Given the respective sections of the base 16 and the envelope, there follows a certain setback of the edge 14 along the throttled part of the neck.
  • the one shown in Figure 2 is specific to the tube when it has just been manufactured.
  • the tube 1 is in fact placed in a rigid tube holder 3 (made of steel for example).
  • the rounded corners 15 of the envelope facilitate its introduction into the recess 31 of the tube holder 3.
  • the latter has a height slightly less than that of the envelope of the tube 1 (cf. FIG. 5) and an elliptical section (cf. Figure 6).
  • the long side of the ellipse is however less than the distance between the two sides 11 and 12 of the unconstrained envelope. Also when the latter is forced into the recess 31 of the tube holder 3, it is caused to deform.
  • the periphery of the tube 1 at rest is shown in dotted lines in FIGS. 5 and 6.
  • the valve 2 can be formed of a simple valve whose actuation frees a passage for the product towards the outside.
  • the hermetically closed tube 1 is removed from the tube holder 3, its elastic walls seek to resume their original shape (cf. FIGS. 7 and 8). They therefore tend to compress the product.
  • the latter is not very compressible, such as a liquid or a paste, this results in an increase in its pressure which therefore becomes greater than atmospheric pressure. Therefore, the simple actuation of the valve causes a lively emission of product to the outside.
  • Its outlet valve opens only if the pressure prevailing in the pump chamber exceeds a certain value determined by a prior setting of elastic means. In this case, this value is chosen to be greater than the maximum pressure of the product, to which is added the additional pressure appearing when the user manipulates the tube. No product is therefore likely to be released unintentionally.
  • the pump really begins to be useful when a sufficient quantity of product has been emitted so that the tube has returned to its initial shape. It allows you to continue extracting the product. For this there is no need for a dip tube since all the volume available inside the tube is occupied by product. For the same reason, emission can be caused in all positions of the tube relative to the vertical. While the evacuation of the product continues, a depression then develops within the tube 1. Its faces 10 therefore begin to approach one another finally giving the shape described by the front, side and in cross section of Figures 9, 10 and 11 respectively. By this means, it is possible to expel between 90% and 95% of the product initially placed in the tube 1.
  • Such a cylindrical bottle 1 is shown just after its manufacture in front view in FIG. 13 and in top view in FIG. 12. It comprises an elongated neck 17 molded in one piece with a body of ovoid shape. The most rounded part of the ovoid has an edge 11 which is equivalent to the sides 11 and 12 of the envelope of the flat tube. It is in fact reinforced by an extra thickness of material while the faces 10 of the body of the bottle 1 are thinner. Furthermore, a bottom 13, also reinforced, makes it possible to give the bottle a seat. It also offers a support point for the thumb, for example of the user, who can thus manipulate it with one hand by passing two fingers over the face 10 of the bottle opposite the bottom 13.
  • the bottle is filled while it is placed in a rigid bottle holder 3.
  • the recess 31 of the bottle holder 3 is this time cylindrical, its inner section having a diameter substantially smaller than the outside diameter presented by the edge 11 when the bottle is at rest (see the outline drawn in dotted lines in FIG. 14).
  • the positioning of the bottle within the recess 31 results in a change in shape which the faces 10 of the bottle allow due to their elasticity. This results in a significant increase in its capacity (for example double the capacity of the unconstrained bottle).
  • valve 2 When the bottle 1 is filled to the brim, a valve 2 is crimped onto its neck 17 so that all the air is absent inside the bottle.
  • the valve 2 is preferably a precompression pump.
  • the pressure prevailing within the bottle also goes through three phases. Initially, the walls of the bottle 1 seek to return to their original shape and therefore compress the liquid or pasty product present in the bottle. Then, over the product emissions, the pressure decreases while the bottle 1 returns to its original size. Finally, the pump 2 authorizing further extraction of the product, the interior of the bottle is placed under vacuum.
  • the flexible faces 10 then approach each other as shown in FIG. 15. The absence of the dip tube allows maximum flattening of the initially ovoid body.
  • the user can favor the latest emissions by pressing on the bottom 13 of the bottle. This possibility is made all the easier since the assembly of the bottle 1 and of the valve 2 constitutes a sprayer operating in all positions. It follows an exhaustion of the product which easily reaches 95% of the initial quantity
