  • 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 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 thanks 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 fixation of the circular projections 44 of the diaphragm in the notch 45 of the tank 10; the lower edge 68 of the cap portion 64 is fixed 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 the possibility of paste passing through the lower edge itself.
  • the rigid jig 58 provides a window 118, so that in an assembled configuration of the rigid jig onto the elastic diaphragm, this window overlaps at least partially said operating portion 108 of the cap 64.

  • 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.

  • the tip 128 has a circular ring shape so as to form a cut-off for the second portion 80 of the eject pipe 76 towards the Y-axis and in a direction removed from the cap itself.
  • the cylindrical length 126 is adapted to accommodate at least partially the second portion of the eject pipe, so as to limit the shifting of the eject pipe to a plane perpendicular to the Y-axis.

  • rigid jig is indicated a jig having such a material and configuration that it is not deformed during the dispensing action 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 deformation of the elastic diaphragm 52 while operating; for example, the ring 122 prevents the eject pipe 76 from moving or inclining 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 forms part of the rigid jig 58.

  • the cylindrical length 126 of the rigid jig 58 is integrally connected with the second portion 80 of the eject pipe 76.
  • the eject pipe 76 is connected or cantilevered relative to the rigid jig 58, i.e. the second portion 80 of the eject pipe 76 is rigidly connected to the cylindrical length 126 of the rigid jig 58, whereas the first portion 78 penetrates into the elastic diaphragm 52 through said housing 138, without being connected with the elastic diaphragm 52. 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 and substantially abuts on the vertex 100 of the cap portion 64, so as to limit the deformation 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 opened, then the operator presses the elastic diaphragm 52 with 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 pressurised 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 component 6 flows through the holes 94 of the eject pipe 76 combining with the main component 5 which is conveyed through the inlet aperture 82 to the eject pipe 76.
  • the paste is conveyed to the inlet aperture 82 of the eject pipe 76.
  • This under-pressure 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 under-pressure 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 a vortex which would compromise the visual aspect as well as the paste composition.
  • the eject pipe Before first use of the delivery device, 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 under-pressure 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-component type paste to be delivered by assuring the composition and the desired aesthetical aspect thereof.
  • the main component is contained in the tank and the minor component in the cap portion.
  • the piston pushes the main component into the eject pipe and the elastic diaphragm directly conveys the minor component to the same duct, so as to provide a multi-component paste having for example, a form consisting of the main component 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 component and equally spaced around the main component.
  • the fastening means of the eject pipe assures the fixing in position of the eject pipe and the desired aesthetical aspect for the delivered paste.
  • the various components are contained in the tank, comprising for example a central pipe containing the main component and a lateral tube nest containing the various minor components.
  • the piston pushes the various bodies in the eject pipe so as to provide the desired multi-component 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, while passing from the shape-retaining configuration to the deformed configuration and vice versa assures that the main component is properly combined with the minor components, thus avoiding the forming of a vortex inside the paste, which would compromise the aesthetical aspect of and the composition of the delivered paste.
  • the delivery device is cost-effective in production and assembly.
