Definitions

• the present invention essentially relates to a device for delivering any product, such as for example a liquid, a powder or a paste, contained in a container or reservoir with a deformable wall.
• Containers with a deformable wall have already been proposed containing means which can be actuated by an external pressure exerted on the deformable wall of the container in order to control a valve capable of closing or opening the container.
• valve control means were constituted by rigid mechanical means and not necessarily suitable for a wide variety of products more or less viscous than can receive the container 20.
• the present invention aims to remedy these drawbacks in particular by proposing a system for opening and closing the valve which is
• the invention relates to a device. delivery of any product contained in a container with a deformable wall containing means which can be actuated by an external pressure exerted c ⁇
• said deformable wall to control a valve allowing the opening and closing of the container, characterized in that said means consist of at least one elastically deformable member which bears on the internal wall of the container.
• this elastically deformable member is constituted by a ring.
• This ring can be an articulated ring or not.
• joints of the ring can be constituted by a web of material coming from molding with the ring.
• the aforementioned ring is mounted on a crosspiece itself mounted inside the container and is itself crossed substantially along its diameter by the valve stem coupled to said ring.
• the ring is supported between a cross member fixed inside the container and the end of the valve stem.
• the ring can form an open loop, the two free ends of which are fixed to the aforementioned crosspiece.
• the ring can be fixed by gluing, for example to the aforementioned cross member and to the stem of the valve.
• the ring can have a shape admitting two orthogonal axes of symmetry, one of which merges with the axis of the rod.
• the ring has the shape of an ellipse or of a polygon inscribed in this ellipse whose large axis merges with the axis of the valve stem.
• Figure 1 is a schematic view in axial section of a container equipped with a valve control system according to the principles of this invention.
• Figure 2 illustrates, in axial section, a container which is equipped with a valve control system according to the invention, but which is here arranged differently.
• Figure 3 is a perspective view of an elastically deformable member capable of being mounted inside the container for controlling the valve.
• Figures 4 and 5 respectively illustrate in axial section, two container variants, corresponding substantially to the embodiments of Figures 1 and 2, but both equipped with an elastically deformable circular ring and not articulated.
• the means for actuating the valve 3, and more precisely the rod 7 which carries this valve are constituted by an elastically deformable member 5 which bears on the internal face of the wall 2 of the tank 1, as is can clearly see in Figures 1 and 2, 4 and 5.
• the member 5 has the general shape of an elastically deformable ring which can be produced for example from a suitable metallic or plastic material.
• the expression "ring” should be understood to mean any circular, elliptical or polygonal shape, regular or not, as will be explained in detail below.
• the ring 5 is constituted by a plurality of elements 5a hinged together so that the ring has a polygonal configuration.
• the reservoir 1 a non-articulated ring of substantially circular or elliptical shape, as shown in FIGS.
• the elements 5a of the ring 5 are articulated by a simple web of material 6 coming from molding with the ring 5 which, in this case, is made of a suitable synthetic material such as polypropylene or polyamide by example.
• the ring 5 is mounted on a cross member 8 fixed inside the container R.
• the rod 7 of the valve 3 passes through an orifice 9 formed in the cross member 8, and -.
• - Crosses the ring 5 substantially along its diameter, while the end of the rod 7, opposite to that carrying the valve 3, is coupled to the ring 5 by passing through this ring.
• the ring 5 constitutes in a way a loop shown here flat, and the two free ends 12 of which are fixed by means of pins or the like 13 on the cross-member 8.
• end of the rod 7 carrying the stop 11 could be fixed by gluing or the like on the ring 5 instead of being mounted passing through the orifice 10, as explained above.
• a spring arranged between the cross-member 8 and the valve 3 to constantly urge the latter in the closed position, that is to say to bear on the orifice forming the seat 4.
• valve 3 closes the reservoir 1 of the container R, thanks to the spring 14.
• the structure and operation of the variant shown in Figure 4 are substantially the same as for the embodiment of Figure 1, except that the variant of Figure 4 uses an elastically deformable circular ring open and not articulated 5.
• This ring made of plastic or suitable metal such as spring steel, has an omega shape whose free ends 18 are clipped into the orifice 9 of the cross member 8, while the rod 7 of the valve 3 is coupled to the part of the ring 5 diametrically opposite its free ends 18, using an appropriate fastening 19 and such as a rivet or a stirrup.
• the ring 5 is supported on a crosspiece 16 inside the container R, this crosspiece being here situated towards the bottom of the container R and comprising, just like the crosspiece 8 mentioned previously, orifices 17 for the passage of the product.
• the ring 5 also bears on the end of the rod 7 which is opposite to that carrying the valve 3 possibly fitted with hair 1 5.
• the opening of the valve 3 is effected here by pushing on the rod 7, against the force of the spring 14, while, in the embodiment of Figures 1 and 4, the opening of the valve 3 s' carried out by traction on the rod 7.
• the ring 5 can be fixed, for example by gluing, to the crosspiece 16, and possibly to the end of the rod 7 of the valve 3.
• FIG. 5 is very similar to the embodiment of FIG. 2, except that here an elastically deformable closed circular ring is used, non-articulated and made for example of plastic or metallic, such as spring steel, possibly protected by an anti-corrosion coating such as a varnish for example.
• an elastically deformable closed circular ring is used, non-articulated and made for example of plastic or metallic, such as spring steel, possibly protected by an anti-corrosion coating such as a varnish for example.
• an elastically deformable member constituted by several rings such as 5 coupled and articulated in the manner of articulated parallelograms for example, so as to increase the opening stroke of the valve.
• the ring (s) 5 can be of any elastically deformable material.
