Definitions

  • the operating method is very simple: In a metal container, made of aluminum or steel, there is a liquid phase and a liquefied propellant.
  • the container is hermetically closed by means of a dispensing valve.
  • the valve is provided with a plastic dip tube, which is long as the container itself, so as to reach the bottom of the container.
  • aerosol mixture While dosing, a part of the liquefied propellant passes from the liquid state to the gaseous state, pressurizing the entire content.
  • the mixture formed by liquid phase and propellant is called aerosol mixture.
  • Pressing the button or dispensing cap operates the dispensing valve. A fraction of the aerosol mixture is expelled through the valve itself. In the can, a new part of the liquefied gas passes to the gaseous state, and so on until the content is finished.
  • the pressure inside the container remains almost unchanged during the entire time of use.
  • the spray features are changed substantially by working on the valve type and on the dispensing stem type.
  • the finished product In order to be released from a can, the finished product, be it hairspray or furniture polish, must follow an obligatory route.
  • a number of channels allows the passage of the aerosol mixture making it exit outwards.
  • the amount of expelled product and the size of the dispensed particles can be varied by varying the diameter of the channels and their number.
  • the appearance of an aerosol product is adjusted by modifying the type of dispensing stem present on the button or on the dispensing cap.
  • the dispensing stem is an accessory which is usually molded separately and then mounted by pressing onto the dispensing cap or onto the dispensing button.
  • the shape, the spray cone and the size of the dispensed product particles is radially modified as the shape of the stem orifice and of the channels upstream of the outlet orifice vary.
  • EP0693439 A1 discloses a spray cap for an aerosol container according to the prior art.
  • the stemless dispenser inserted in the second step is instead less complicated to make, and therefore less expensive, because the orifice which allows the release of the product is made in a single operation during the molding of the dispensing cap.
  • a dispensing cap is formed by a fixed part, the cap body, and a movable part, constrained to the body as a lever, which works as actuator.
  • the valve dispenses by pressing the actuator.
  • the plastic is injected in the cavity and takes the shape of the mold.
  • the idea is to suggest multiple different dispensing types, incorporating in the mold the actuating part of the cap, the number of channels, the pattern thereof and the diameter of the orifice necessary to obtain a given type of spray.
  • the core of the model is also the button of the dispensing cap, which is the movable upper part of the dispensing control.
  • a dispenser capable of dispensing aerosol in powder form (e.g. deodorants with antiperspirant).
  • the solution was to apply a second injection of polypropylene in the mold, which generates a plastic button adherent to the body of the dispenser which eliminates the release of the product from the body of the dispenser during dispensing.
  • the dispensing system substantially includes three parts.
  • the main body consists of a lower ring 2 followed on top by a smaller concentric ring 1.
  • the upper part 3 is substantially spherical and joined to the lower part 1-2 by a circular rib sector or pin S1 with width of about 45° and by a seal rib S2 of limited width which in the step of first using of the dispenser is broken by pressing on the upper part to be able to dispense the product.
  • the spherical upper part 3 has on one dispensing side a wall 4 with an orifice 5 of diameter 2-3 mm, which is placed in upper position on the wall 4 and to which a circular groove 4A is attached in the lower part, which has the function of distributing the product towards the fan 7A (shown in Figure 2 ).
  • the product which exits from the orifice 5 by effect of the pressure of the can, follows a distribution path in the chamber along the circular channel 4A, the center of which coincides with the axis of the orifice-fan 7-7A.
  • the fan 7A receives the product and dispenses it from the orifice 7, which may have different sizes, to modify the jet also on the outer face.
  • the outer part of the tongue 6 may also have incision of different shapes to modify the jet or be a spherical shaped cavity or other type of recesses either provided with fluid diversion incisions or not.
  • the dispensing fan 7A will be applied after the operation of assembling the upper cap 3. The fan 7A causes the circular distribution of the product which then exits from the front orifice 7.
  • the upper cap part with nozzle-fan is formed by a platform 8 with a recess 9, shown in greater detail in Fig. 2 , with two wings A1 and A2 with various cross sections directed downwards, which will be inserted in two cavities 8A shown in Figure 5 .
  • Two rod-like connections C1 and C2 are present between stem cap and the spherical part 3.
  • a flat tongue 6 provided with orifice 7 is provided in the part of the cap visible from the front.
  • a static fan 7A with various blade shapes is carved in the inner part of the tongue 6 in order to obtain a desired spraying jet type.
  • the outer part of the tongue 6 may have different shapes.
  • the upper recess 9 of approximately rectangular shape rounded on the front part makes it possible to fix the upper molded button 17 ( Fig. 4 ) which will be successively applied with the second plastic molding.
  • the spherical part 3 in the lower part has a tubular protrusion 11, which is the can valve attachment, joined to the spherical part 3 with two ribs 12, 13.
  • the rib 13 connects to part of channel wall 4 which accommodates the tongue 6 with the nozzle-dispensing fan 7 shaped as a fan 7A in the lower wall.
  • the orifice 7 may have different sections of various shape.
  • the cavity 15 which can be seen in this figure will be successively used to accommodate the second molding of the upper button 17, which molding will also cover the step recess 9.
  • In the upper part of the sphere there is a flat part 10 which will also accommodate part of the upper button 17 ( Fig. 4 ) made of different color.
  • Fig. 3 shows the final position of the cap 8 when it was compressed in its housing 14 and in the holes 8A' which can be seen in Fig. 5 and part of the nozzle-fan tongue 6 fitted in its housing 14.
  • Figure 4 shows the button 17 already applied with the second molding of plastic material of different material and/or color which adheres to the housing 15 but peripherally surrounds the fan-nozzle system 7 and 7A. Furthermore, in the molding of this part of different or the same color, an outer plastic winding is formed which joins the housing 15 on the front. Such element hermetically closes the spray chamber between the wall element 6 and the aforesaid wall 4. So, after the application of the hot molding of the upper button 17, a unitary body of the dispensing body 3 and of the button 17 is obtained, which during the use of the dispensing can oscillate about the front pin S1 when the minimum rear seal S2 is broken.
  • Fig. 5 shows the cavities 8A' which accommodate the wings 8A during the molding of the upper button 17.
  • This arrangement system makes it possible to avoid the manufacturing and the assembly of a nozzle-fan insert 17 which was previously manufactured separately and then mounted in its front housing of the dispenser, fact which represents a high economic advantage for saving time and materials.
  • the nozzle-fan 7-7A may have various inner blade shapes with various distance intervals between them and various blade shapes or also with a calibrated orifice of circular or other shape, according to the desired spraying purposes.
  • the presented model is not bound to the exact spherical shape, but may have other shapes on top, e.g. pyramid or egg-shaped, or other shape providing the lower circular shape is maintained for the connection with the can of the material to be dispensed.
