Definitions

  • the present invention relates to an airless dispensing device, such as a airless pump, i.e. without return air so that the product dispensed is never in contact with air before distribution.
  • a airless pump is especially used for the distribution of products which are likely to be deteriorate on contact with air. It can be pharmaceuticals like cosmetic products.
  • this type of dispenser includes a variable volume distribution with an inlet with an inlet valve and a outlet with an outlet valve.
  • a piston is provided which is generally actuated by means of a so-called rod actuation through which the product is forced out of the chamber. This is there of a completely classic design for an airless pump.
  • the vacuum tank To avoid any possibility of damage to the product to be distributed on contact of air, it is preferable to fill the vacuum tank and to mount the distribution on the tank always under vacuum.
  • the inlet valve which can be present under the shaped like a ball, washer or tapered flange member, which does not provide a perfect seal during this fixing operation of the vacuum distributor.
  • the valve seats do not have a sufficiently perfect surface finish to ensure perfect air tightness. As a result, air is also exhausted from the distribution chamber and there then reigns a partial vacuum.
  • the dispensing head is not still mounted on the valve actuator rod.
  • the vacuum is interrupted once the dispenser is attached to the tank, the tank and the pump are again subjected to atmospheric pressure so that all voids to inside the tank but also inside the distribution chamber are suddenly filled with the product contained in the tank. So there follows a at least partial filling of the distribution chamber.
  • a major drawback is then produced when the dispensing head is mounted on the actuating rod, which has the effect of moving the rod and thereby the piston and thus reducing the volume of the distribution chamber at least partially filled with product. This results in therefore a distribution of the product contained in the distribution chamber.
  • the product fulfills the actuating rod and the distribution head ejection channel. This product is good obvious in contact with outside air and can therefore deteriorate.
  • the present invention aims to overcome this drawback of the art by defining a distributor whose entry is initially closed by a cap easy to install without complicating the molding and which does not risk interfere with the operation of the dispenser once it is dislodged from its sealing position.
  • the present invention provides a dispensing device without air intake, such as an airless pump, for dispensing a fluid product, said device comprising a variable volume distribution chamber provided with an inlet provided an inlet valve and an outlet provided with an outlet valve, said distributor further comprising a piston for varying the volume of the distribution, closure means being provided for sealingly closing the distribution chamber substantially at its entrance before its first use, the closure means being formed by the inlet valve.
  • the outlet valve being perfectly sealed, the means for closing the inlet allow to insulate in a perfectly airtight manner the interior of the distribution. Thus, it is impossible for an air vacuum to be established inside.
  • the piston is mounted on an actuating rod having one end protruding inside the distribution chamber, said end forming a thrust member capable of pushing the inlet valve out of its position at the end of its travel waterproof in its normal working position.
  • the inlet valve is a wedged ball of tightly in a sleeve.
  • the inlet valve is a member with a conical flange comprising a protruding peripheral sealing cord stuck in the entrance to the distribution.
  • the distribution chamber is perfectly isolated from the outside and therefore does not undergo the vacuum which reigns when the distributor is attached to the tank.
  • These sealing means are only released during assembly of the head. distribution on the actuating rod, which has the effect of moving the rod inside of the chamber until its end moves the closure means so to establish communication between the chamber and the tank.
  • inlet valve By using the inlet valve to seal the inlet, there is no need to mold a plug as in the previous art, and once dislodged, the valve is not likely to interfere with the operation of the dispenser.
  • this airless pump comprises a body 1 defining a cylinder 10 in which is mounted a piston 3 mounted on the actuating rod is slidably mounted.
  • the end lower part of the body 1 has an inlet 12 defining a valve seat 13 of frustoconical shape. At its upper end, the body 1 forms a flange of attachment 11 which projects radially outwards. This flange 11 allows the gripping the pump using a crimp ring 83.
  • a crimp ring 83 For sealing the pump on the tank (not shown), there are two O-rings 81 and 82 which are placed respectively between the flange 11 and the crimping ring 83 and between the upper end of the tank (not shown) and the crimp ring 83. The fixing of the pump on the neck of the tank (not shown) is therefore perfectly airtight.
  • the cylinder 10 formed by the body 1 internally receives a piston 3 which is itself slidably mounted on the actuating rod 2.
  • the piston 3 is biased in its high rest position represented in FIG. 1 by a return spring 7 which acts by means of a gland 4 which rests on the piston 3.
  • the rod actuation 2 is biased in its rest position shown in Figure 1 by a spring 4 which bears on the piston 3.
  • the actuating rod 2 defines so conventional an outlet duct 21 which defines near its lower end two lateral openings 22 closed in the rest position (fig. 1a) by the piston.
  • the arrangement formed by the lower end of the actuating rod 2, the piston 3 and the gland 4 constitute the outlet valve of the airless pump.
  • the pump body 1 forms a pump chamber 14 of variable volume.
  • the pump chamber is conventionally provided with a inlet valve 51 which is shown in Figure la in the form of a spherical ball. he can also be considered other forms for the inlet valve such as example a member with a conical flange (fig. 2a and 2b).
  • the ball 51 does not rest on its seat valve 13 but is engaged in a sleeve 61 in which it is stuck.
  • This sleeve is formed by a substantially cylindrical part 6 engaged inside the body 10 and resting on the bottom of the body being pressed by the spring 7 which is supported with its lower end 71. Consequently, the cylindrical part 6 is kept perfectly in place inside the body 10.
  • the cylindrical part 6 further defines lateral grooves 62 for the passage of the product.
  • the inlet valve 51 does not rest on its seat 13 so that it cannot fulfill its function of selective closing of the entrance 12 of the room pump 14.
  • the pump chamber 14 is perfectly insulated from the outside so airtight.
  • the ball 51 wedged in the sleeve 61 prevents any passage of air at the entrance to the pump chamber, and other hand, the positioning of the piston 3 on the lateral openings 22 of the rod actuation 2 prevents any passage of air at the level of the chamber outlet valve
  • the pump chamber 14 therefore defines an isolated space.
  • a conventional dispensing head includes a connection 91 internally defining a channel 92 which is extended laterally by an outlet duct 93 ending in a dispensing spout 94. Externally, the dispensing head 9 can form a peripheral skirt 96 which extends downwards to hide part of the pump and actuation rod 2. To perform the fitting of the dispensing head 9 on the actuating rod 2, it is necessary to position the sleeve 91 in alignment with the rod 2 then to exercise a pushing force on the surface 95 of the head 9 so as to achieve the fitting shown in Figures 1b and 1c. When we exercise this pushing force on the surface 95, the actuating rod 2 is biased downwards inside the body of the pump by driving with it the piston 3.
  • the depression of the actuating rod in the body 1 has the effect of reducing the volume of the pump chamber 14 against the action of the return spring 7.
  • the actuating rod 2 is pushed in inside the body, the piston 3 and the gland 4 move on it in the opposite direction to so as to unmask the side openings 22, which establishes an air passage between the pump chamber 14 and the exterior via the channel 21, the conduit 92 and the channel 93.
  • the outlet valve opens when the pressure inside the pump chamber 14 is sufficient to push back the piston 3 and unmask the side openings 22. If one continues to exert a push on the actuating rod 2, it continues to run inside the pump body until its lower end 23 comes into thrust contact on the ball 51 stuck in the sleeve 61.
  • the end 23 of the rod 2 reaches dislodge the ball 51 from its sleeve 61 as can be seen in Figure 1b.
  • the lower end 23 of the rod 2 serving as a thrust member manages to completely disengage the ball 51 from the sleeve 61 so that it can be positioned on the conical inlet valve seat 13, which constitutes its normal working position allowing selective closure of the inlet 12 of the pump chamber 14.
  • the inlet valve in this case a ball 51 serving as means shutter to isolate the chamber 14 during the vacuum crimping operation, is then pushed into its normal working position using the lower end of the actuating rod 2 serving as a thrust member during mounting of the distribution 9 on this actuating rod 2. Consequently, the release of the ball 51 of its sleeve 61 is possible without additional part and without operation additional, since the mounting of the actuating head 9 on the rod 2 is a conventional and compulsory operation.
  • a secondary advantage also results from the use of the cylindrical part 6 to form the sleeve 61 used for wedging the ball 51.
  • this cylindrical part 6 makes it possible to define with the valve seat 13 a space defining a housing in which the ball 51 is trapped, so that its freedom of movement is limited. This ensures that the ball 51 will always come in perfect position on its valve seat 13.
  • valve inlet in the form of a member 53 having a conical flange 54 intended for cooperate with the conical surface 13 of the valve seat.
  • the shutter function performed by the shutter ball 52 is then provided by a peripheral sealing bead protruding 55 adapted to be positioned at the level of the inlet 12 just like the ball 52.
  • the member 53 is then simply pushed by the push pin 23 which forms the lower end of the actuating rod 2 so that the cord is released from the inlet 12 and that the conical flange can then come to bear sealing against the conical surface of the inlet valve 13.
  • valve member instead balls 51 and 52 offer several advantages.
  • a member can be molded in plastic, which is on the one hand less expensive, and on the other hand advantageous from the point of view of recycling capacity.
  • the invention it is possible to insulate in a perfectly airtight manner the distribution chamber 14 during a fixing operation, in particular of crimping, in a very simple way.
  • the release of resources shuttering is carried out very simply without additional operation or organ.
