Definitions

  • the present invention relates to a dispenser of viscous products, such as liquid or pasty soap, comprising a lower part housing a device for dispensing doses of the viscous product, through an outlet mouth in the form of a tubular projection, actuated by a control member and a shell surmounting said lower part arranged to house the product to be dispensed in bulk or in an adequate packaging, the outlet mouth being capped by a cap perforated with an elastically deformable material, the cap being provided with the dome-shaped outlet end of an opening closed in the dispenser rest position and opening under pressure leading to the expulsion of a dose of the product to be dispensed.
  • a dispenser of viscous products such as liquid or pasty soap
  • Such dispensers are mainly used in public places where human beings need to wash their hands, such as toilets, medical offices, factories, ...
  • the present invention aims to overcome the aforementioned drawbacks by proposing a dispenser preventing, on the one hand, the remaining drop in the outlet outlet of the dispenser from falling and, on the other hand, avoiding the possible sealing of said mouth if the dispenser is not used for a relatively long time interval.
  • the dispenser according to the invention is characterized in that said opening is a slot, that the lower part of said dispenser and the dispensing device and the outlet mouth capped with the elastically deformable cap are arranged so that when the control member arrives at the end of the race, in the product expulsion phase, it removes a small internal volume from said elastically deformable cap, said volume being recreated when the control member returns to its initial position thus causing a depression inside said elastically deformable cap.
  • the advantage of this device is that the outlet mouth is in the rest position closed practically hermetically, since the cap made of elastically deformable material thanks to its shape and the single slot can be considered in the rest position as tightly closed, which prevents the product from drying out and blocking the mouth.
  • the quantity of the product located inside the mouth cannot fall by gravity since the cap remains closed until a pressure is exerted on the product to cause the opening of the slit. on the dome end of the cap.
  • the vacuum created during the return phase makes it possible to ensure good closure of the slot, and even to suck up, in particular with particularly viscous products, a small part of the product which remains attached to the lips of the slot outside. of the cap and can cause the same drawbacks mentioned above.
  • the outlet mouth and therefore the cap are integral with a part driven by an alternating linear movement moving in one direction in the phase of expulsion of the product and in the opposite direction for return to the rest position; in addition, the tubular projection of the outlet mouth is provided with a countersink covered by the cap and when the outlet mouth reaches the end of the stroke in the expulsion phase it comes into contact with a projection which enters said countersink by leaning on the cap and taking advantage of its elastic deformation properties to remove a small volume inside the cap and restore it when the outlet mouth begins the return movement towards the rest position thus causing a vacuum allowing the product located outside the cap to be sucked on the lips of the slot .
  • the dispensing device is arranged so that during the return phase the outlet mouth is in communication with a chamber provided with a valve isolating the chamber from the rest of the dispensing device which ensures a reduction in the pressure in said chamber with respect to the pressure during the expulsion of the product and thus making it possible to amplify the depression in the outlet mouth hermetically closing the slot and aspirating the possible drop of the product which could have remained outside.
  • the single figure is a side sectional view of a dispenser according to the invention.
  • the dispenser comprises a lower part 1 and an upper part 2.
  • the upper part 2 is formed of a shell essentially in two parts, a part 2a intended to be fixed against the wall of the room in which the distributor is intended to be used and a second removable part 2b to allow the installation in the dispenser of a package 3 containing the product to be dispensed.
  • Part 2b is provided with a window f located on its lower part to allow visual control of the quantity of product remaining inside the packaging 3.
  • the lower part 1 essentially comprises a body 4 intended to house the device for dosing and expelling the product and it can also be provided with means for being fixed against the wall.
  • the packaging 3 containing the product is placed in a housing 5, in principle cylindrical, provided in some cases with a device 6 to cause the perforation of the plug closing the packaging 3.
  • the housing 5 communicates with a lower chamber 7 which its side is in communication with a first cylindrical chamber 8 whose end communicating with the chamber 7 is closed by a ball 9 pushed against the outlet orifice of said chamber 8 by a spring 10 which is supported on the other side against a shoulder of a hollow piston 11.
  • One end of the piston 11 moves in leaktight manner inside the chamber 8 by means of a seal 12.
  • the hollow piston 11 is located inside a housing 13 of the body 4.
  • the hollow piston 11 has, at about mid-length, an external shoulder 14 against which a spring 15 bears, its other end pressing against another shoulder 29 outside the chamber 8.
  • the spring 15 aims to pull the hollow piston outside of chamber
  • the hollow piston 11 is closed at its second end by a screw plug 16 opening into a bore 17 which continues by another bore 18 of diameter smaller than that of bore 17.
  • the communication between the two bores is closed by a ball 19 thrust against a shoulder 20, between the two bores of different diameter, by a spring 21 pressing at its other end against the plug 16.
  • the bore 17 forms a chamber terminating in an outlet mouth 22 formed by a tubular projection capped by a cap 23 whose lower end is dome-shaped and is provided with a slot 24, which preferably is a cruciform slot.
  • a lever 25 articulated around an axis 26 is linked to the hollow piston 11 so that when the lever is moved in the direction of the arrow F, the hollow piston moves in the opposite direction, that is to say interior of the chamber 8.
  • the tubular projection 22 is provided with a countersink 27 while approximately in the same horizontal plane the lower part of the distributor is provided with a horizontal projection 28.
  • the dispenser works as follows:
  • the product in the package 3 which is also provided with a relatively heavy cover 3a to push the product down and prevent it from sticking to the wall of the package, comes into the chamber 7.
  • the device for expelling the product is already primed, that is to say that the chamber 8, the bores 17 and 18 are already filled with the product to be dispensed and we will come back by the continued on how to boot the device.
  • the hollow piston 11 moves inside the chamber 8 which causes a reduction in the volume of said chamber and the product which is there is pushed towards the ball 19 causing its displacement against the spring 21 thus allowing the product to pass into the bore 17 and push the product which is there in the mouth 22 also causing an overpressure in this part which results in the opening of the slot 24 letting out a dose of product.
  • the hollow piston 11 comes to rest against the ball 9 which coincides with the end of the stroke or the expulsion of the product.
  • the projection 28 partially crushes the cap 23 and tends to enter the countersink 27 of the mouth 22.
  • the chamber 8 regains its dimensions initials that is to say that a depression is created in the space formed by the chamber 8 and the bore 17, which causes the return of the ball 19 against the shoulder 20 thus closing the communication of the bores 17 and 18 and in this case the depression created in the space 8, 18 causes the withdrawal of the ball towards the interior of said space thus leaving the product being in the chamber 7 to refill the chamber 8 until there is pressure balance between the two sides. So the process can continue.
  • the depression created in the chamber 17 amplifies that created in the volume of the sleeve 23.
  • the operation is the same except that at the start there is only air in the different parts and it is advisable to actuate the lever several times to cause the evacuation of the air therein. and allow the product in chamber 7 to enter. To achieve this result, of course, it is necessary to reckon with quality adjustments and sealing.
