  • the central body 110 is provided with a wholly cap shape and is adapted to cover at least partially the cap portion 64 of the elastic diaphragm 52.
  • the rigid jig 58 is at least partially in connection with the elastic diaphragm 52 so as to assure that in the deformed configuration of the elastic diaphragm 52, the latter is not deformed at least at the contact position with the rigid jig 58.
  • the rigid jig is counter-shaped relative to the portion of the elastic diaphragm comprising the eject pipe 76, so that in a deformed configuration of the elastic diaphragm 52, the portion of the elastic diaphragm 52 comprising the eject pipe 76 does not substantially change its own shape; in other words, the rigid jig 58 assures the substantial shape-retaining ability of that portion of the elastic diaphragm 52 in direct contact with it.
  • the portion of the elastic diaphragm 52 being in direct contact with the rigid jig 58 comprises the eject pipe 76, so as to assure that the eject pipe 76 in the shape-retaining configuration is parallel to the eject pipe 76 in the deformed configuration.
  • the central body 110 comprises a fixing portion 114, preferably of a cylindrical shape, adapted to fasten the central body 110 at the second end 22 of the tank 10, so as to block in position the lower edge 68 of the diaphragm 52 in contact with the tank 10.
  • the fixing portion 114 covers the coupler portion 42 of the tank 10 according to a forced coupling, so as to press the lower edge 68 of the cap portion 64 against said coupler portion 42.
  • the fixing portion 114 assures the seat blocking of the circular projections 44 of the diaphragm in its respective notch 45 of the tank 10; the lower edge 68 of the cap portion 64 is stapled between the fixing portion 114 and the coupler portion 42.
  • the fixing portion 114 contributes to confer rigidity to the lower edge 68 of the diaphragm so as to avoid possible paste drawings through the lower edge itself.
  • the rigid jig 58 provides a window 118, so that in an assembly configuration of the rigid jig onto the elastic diaphragm, this window overlaps at least partially said operating portion 108 of the cap 64.
  • the operating portion 108 of the cap 64 is easy to be reached by an operator through the window, so as to allow a finger to be leant in order to cause the cap to be deformed and obtain the delivery of the paste through the eject pipe.
  • the rigid jig 58 comprises a ring 122, being substantially hollow and rigidly connected to the central body 110, and adapted to coupling at least partially with said eject pipe, particularly with the second portion 80 of the eject pipe 76.

  • rigid jig is indicated a jig having such a material and configuration that it is not deformed during the starting of the delivery device 3 i.e. while the elastic diaphragm 52 is passing from the shape-retaining configuration to the deformed configuration.
  • the function of the rigid jig 58 is to control the deforming of the elastic diaphragm 52 while operating; for example, the ring 122 prevents that the eject pipe 76 may be moved or inclined so that the Y-axis of the eject pipe is substantially parallel to the X-axis of the tank 10.
  • the rigid jig 58 and the elastic diaphragm 52 are enbloc moulded, for example by means of double-moulding techniques.
  • the eject pipe is not part of the elastic diaphragm 52, but it belongs to the rigid jig 58.

Accordingly, the first portion 78 is cantilevered relative to the second portion 80 which is rigidly fastened to the rigid jig 58.
  • the ring 122 comprises a stiffening wall 140 which cooperates with the cap 136 at one end in the direction of the second portion 80, and substantially abuts on the vertex 100 of the cap portion at one end in the direction of the cap portion 64, so as to fasten the deforming of the cap portion along the X-axis.
  • said stiffening wall 140 is included between said X-axis and Y-axis.
  • the cap 136 is open, then the operator presses for example the elastic diaphragm 52 by one finger in the direction of the thrust unit 34.
  • the piston 36 of the thrust unit 34 is supported by the flexible ring 38, thus it can not move to the first end 16 of the tank 10 along the X-axis.
  • the paste contained in the tank 10 is raised steam and obliged to flow through the first portion 78 of the eject pipe 76.
  • the volume of the paste ejected is substantially equal to the volume obtained by deforming the cap portion 64, i.e. the difference between the volumes of the shape-retaining cap portion 64 and the deformed cap portion 64.
  • the minor body 6 flows through the holes 94 of the eject pipe 76 combining with the main body 5 which is conveyed through the inlet aperture 82 to the eject pipe 76.
  • a delivery device 3 comprising a multi-mould paste 4 having several bodies in the tank 10, as illustrated for example in figures 5, 6, 7 and 8, the paste is conveyed to the inlet aperture 82 of the eject pipe 76.
  • This vacuum has the effect of pushing the piston 36 towards the second end 22 of the tank 10, causing the feed of the piston itself.
  • said vacuum being generated inside the delivery device has the effect of drawing in an amount of air through the eject aperture 106 so as to push an amount of paste that is in the eject pipe towards the inlet aperture 82 of the pipe itself.
  • the length and section of the eject pipe are set up by physical and geometrical parameters of the paste and the tank, as known in the art, so as to assure that the eject pipe is never completely empty, thus preventing that the air may enter the tank.
  • the feed of the piston assures that the outlet length, i.e. the second portion 80 of the eject pipe 76 is always filled at the end of each paste pumping, so as to avoid the forming of vortex which would irreparably endanger the visual aspect as well as the paste composition.
  • the eject pipe is at least partially filled with paste, so that when the elastic diaphragm is first put into operation, the paste completely fills up the eject pipe, thus preventing that the air may enter during the following intake or vacuum step.
  • fastening means 51 particularly of the rigid jig 58 assures that the eject pipe 76 in its shape-retaining condition is parallel to the eject pipe 76 in its deformed configuration.
  • the delivery device 3 according to the invention allows drawbacks that may exist in the delivery devices of the prior art to be overcome.
  • the described delivery device allows a multi-mould type paste to be delivered by assuring the composition and the desired aesthetical aspect thereof.
  • the main body is contained in the tank and the minor body in the cap portion.
  • the piston pushes the main body into the eject pipe and the elastic diaphragm directly conveys the minor body to the same duct, so as to provide a multi-mould paste having for example a die consisting of the main body and a certain number of stripes, equal to the number of holes that are on the sidewall of the eject pipe, being composed by the minor body and in equal distance from the die of the main body.
  • the fastening means of the eject pipe assure the blocking in position of the eject pipe and the desired aesthetical aspect for the delivered paste.
  • the various bodies are contained in the tank, comprising for example a central pipe containing the main body and a lateral tube nest containing the various main bodies.
  • the piston pushes the various bodies in the eject pipe so as to provide the desired multi-mould configuration; following the operation of the elastic diaphragm, the parallelism of the eject pipe assures the preservation of the paste thus combined in the duct itself.
  • the parallelism of the eject pipe with the X-axis of the tank assures that the main body is properly combined with the minor bodies, thus avoiding the forming of vortex inside the paste, which would endanger the aesthetical aspect and the delivered paste composition.
  • the delivery device is cost-effective in order to be embodied and assembled.
