Definitions

  • the invention relates to a dispensing head with a discharge channel for discharging products such as foams, such as shaving cream or gel, self-foaming products and other applicable with a pressurized system products, from a pressurized conventional dispensing container, which is attachable to the discharge valve of the dispenser container and by an external mechanical pressure exerted thereon and a tilting movement of its upper part about a pivot point open the dispensing valve of the dispensing container so that the product flows in from the dispensing valve into the dispensing channel with overpressure and exits the dispenser head through its dispensing opening.
  • products such as foams, such as shaving cream or gel, self-foaming products and other applicable with a pressurized system products
  • the US Pat. No. 5,309,530 proposes a dispensing head with an additional closure device, which is placed on the valve of a conventional dispensing container and which consists of three construction elements.
  • an upper and a lower valve housing part form the discharge channel, whose discharge opening is pin-shaped from the inside through a discharge channel arranged in the discharge channel formed elastic valve body with valve head is closed and opened.
  • the valve head opposite end of the valve body is angled upwards and ends in a button above a Tastmulde the upper valve body part.
  • the lower valve housing part is pushed onto the dispenser container, wherein a corresponding recess of the dispenser container is attached to the valve of the dispenser container.
  • a disadvantage of this known dispenser head is that at the end of the dispensing operation, the closure of the dispensing container valve and the closure the discharge opening takes place in two stages which follow one another in succession, so that the product located in the discharge channel and under overpressure can at least partially escape from the discharge opening.
  • the object is achieved for a dispensing head of the type mentioned by the characterizing features of claim 1, characterized in that the restoring element is resiliently biased in the closed position and designed so that the opening and / or closing of the discharge takes place automatically and the automatic opening and / closing is supported by the over-pressurized product.
  • the inventive design of the dispenser head with its own closure for the discharge opening of the product after use is reliably prevented.
  • the closure device of the dispenser head which can be placed on any conventional aerosol valve, consists in particular of a valve housing, which forms part of the dispensing channel arranged in the top of the dispensing head, a pin-shaped valve body with a valve head for closing the dispensing opening and a return element.
  • the return element is formed from an elastic dome, in the semicircular rear wall, an inner sleeve is arranged, in which the valve head opposite end of the valve body is inserted.
  • the elastic dome pulls the valve head of the valve body from the outside against the discharge opening of the discharge channel by its residual stress and closes it.
  • the position of the elastic Dome with respect to the usual pivot point for the tilting movement of the upper part of the dispenser head is chosen so that its elastic back wall guided in the tilting movement on a circular path against a stationary web of the lower part of the dispenser head and this deformed and by a certain amount in the direction is moved to the discharge opening.
  • the elasticity and existing before deformation residual stress of the elastic dome is so large by appropriate choice of material that after the provision of the upper part of the back wall of the dome returns to its original position and thus retracts the valve head of the valve body from the front to the discharge of the discharge channel. This process is supported by the excess pressure in the valve housing product, which against both the valve head and against the back wall of the dome suppressed.
  • the effective area of the rear wall according to the invention is greater than the effective area of the valve head, as a result of the overpressure of the product on the regression of the rear wall and thus affects the closure of the discharge.
  • valve body whose valve head closes the discharge opening from the front, anchored latching in a valve body sleeve.
  • the rear part of the valve body sleeve is made as a return element of an elastic double wall and fixedly connected to the upper part and / or the lower part of the dispenser head.
  • this elastically formed rear part of the double wall is guided in a circular path against a stationary web of the lower part, thereby deformed and displaced with the valve body in the direction of the discharge opening.
  • the valve head releases the previously closed discharge opening to the outside.
  • the rear part of the discharge opening closing from the inside valve body is double-walled and filled with the product to be discharged.
  • the outer valve body wall is made of an elastic material and serves as a restoring element, for which purpose the front part of the elastic valve body wall is fixedly connected to the upper part and / or to the lower part of the dispensing head.
  • the elastic valve body wall is set in the initial position under tension so that the conical or round tip of the valve head is pulled from the inside against the correspondingly formed nozzle mouth of the discharge and sealingly seals it.
  • the product to be discharged flows with positive pressure into the double wall of the valve body.
  • the pressure exerted on the inner rear wall of the double wall in this case is greater than the tensile stress in the elastic region of the valve body wall, so that the valve body is drawn inwards and the discharge opening is exposed to the inside.
  • the tensile stress already present in the starting position is thereby increased while stretching the elastic region of the valve body wall.
  • the voltage present in the elastic valve body wall extends to an automatic return of the valve body and a renewed closure of the discharge opening.
  • the elastic part of the valve body sleeve (second embodiment) or the valve body wall (third embodiment) is connected in a one-piece production by injection molding with the rest of the inelastic part of the valve body sleeve or the valve body wall in a special injection molding process (2-component injection molding).
  • a corresponding elastic material such as TPE (thermoplastic elastomers), chosen so large that it is sufficient to pull the valve body back to its original position after completion of the dispensing operation and provision of the tilted upper part and the Close the discharge opening again tightly with the valve head.
  • the valve body is formed in a similar manner as in the third embodiment with a double wall, which is filled with the product to be discharged.
  • the double-walled rear part of the valve body against a projecting rib of a stationary web, and the valve head is sealingly against the discharge from the inside, the rear elastic region of the double wall is compressed.
  • the bridge and its rib are arranged so that through the circular Tilting movement of the upper part during dispensing operation of the valve body is rotated out of the lock.
  • valve body pulls inwards, whereby the valve head releases the discharge.
  • the valve body is manually pushed back against the discharge opening by the projecting rib and this is thereby closed, with the elastic region of the double wall of the valve body being compressed again.
  • FIG. 1 shows a vertical section of a dispensing head 1 with a closure device 1 'according to the invention in the starting position. It consists of a valve housing 4, which is at the same time part of the upper (horizontal in the drawing) discharge channel 2 and arranged at right angles to the container axis 15 is a pin-shaped valve body 5 with a valve head 7 and an elastic return element or Dom 6 (see also Figures 5 to 8).
  • the front part of the valve housing 4 terminates at a distance from the front edge 16 of the upper discharge channel 2 with the discharge opening 3 and the rear part of the valve housing 4 (in the drawing on the right) is formed by the turned-up elastic dome 6.
  • the semicircular rear wall 12 of the mandrel 6 has inside a sleeve 8, in which the valve head 7 opposite tapered end 18 of the pin-shaped valve body 5 is inserted.
  • the length of the pin-shaped valve body 5 is dimensioned so that in the starting position of the dispenser head 1 by the residual stress of the elastic mandrel 6 of the valve head 7 is pulled from the front against the discharge opening 3 and closes it.

  • the dome 6 was guided on a circular path with its semicircular rear wall 12 against the fixed web 9 down towards the dispenser container, whereby the rear wall 12 was deformed and moved in the direction towards the discharge.
  • valve body 5 By this displacement of the rear wall 12 and the inside of the rear wall 12 inserted into the sleeve 8 valve body 5 has been moved with its valve head 7 in the same direction, thereby releasing the discharge port 3. In this dispenser position, the product already contained in the valve housing 4 can emerge from the discharge opening 3.
  • closure device 1 ' is that the contact pressure of the valve head 7 on the discharge opening 3 not only by the residual stress of the elastic dome 6, but in addition by the different sized, acted upon by the product with pressure effective surfaces 13, 14 of rear wall 12 and valve head 7 is effected. Since the effective area 14 of the rear wall 12 of the mandrel 6 is substantially larger than the effective area 13 of the valve head 7, a resultant force results, which acts only on the rear wall 12 with the result that the greater the overpressure, the higher the higher the force with which the valve head 7 is pulled against the discharge opening 3, and the higher the tightness of the system. The stated object of the invention to suppress repressions of the product after the end of the dispensing process is thus achieved.

    la partie arrière du corps de valve (45, 65) faisant office d'élément de rappel est doté d'une double paroi, dont une paroi de corps de valve extérieure élastique (46, 66), et peut être rempli avec le produit à évacuer, la partie avant de la paroi de corps de valve élastique (46, 66) étant solidarisée au moyen de bourrelets annulaires (46', 46", 66', 66") avec la partie supérieure (50, 70) et/ou avec la partie inférieure (51, 71) de la tête de diffusion (40, 60) et la tête de soupape (47, 67) ferme l'ouverture d'évacuation (43, 63) de l'intérieur.
  9. Tête de diffusion (1, 20, 40) selon une des revendications 3 à 8,
    caractérisée en ce que
    la tension propre de l'élément de rappel élastique (6, 26, 46) est telle qu'après la fin de l'opération de diffusion et le retour de la partie supérieure (10, 30, 50) basculée, elle soutient activement les forces de propulsion de la pression résiduelle du produit, pour remettre le corps de valve (5, 25, 45) dans sa position initiale et ainsi refermer l'ouverture d'évacuation (3, 23, 43) avec la tête de valve (7, 27, 47).
  10. Tête de diffusion (20, 40, 60) selon une des revendications 5 à 8,
    caractérisée en ce que
    la partie élastique (26) du manchon de corps de valve (28) ou la partie élastique (46, 66) du corps de valve (45, 65) est reliée, par un procédé de moulage par injection spécial (moulage par injection à deux composants) avec la partie restante non élastique du manchon du corps de valve (28) ou du corps de valve (45, 65), avec laquelle elle forme une seule pièce.
  11. Tête de diffusion (60) selon la revendication 1 ou 2,
    caractérisée en ce que
    le corps de valve (65) est configuré avec une double paroi (72) pouvant être remplie avec le produit à évacuer et, dans la position de départ, est pressée avec sa tête de valve (67) de l'intérieur contre l'ouverture d'évacuation (63), par une nervure saillante (69') d'une ailette fixe (69) de la partie inférieure (61) qui se verrouille sur son extrémité arrière (72'), et la région arrière élastique (66) de la double paroi (72) est ainsi comprimée, l'ailette (69) avec sa nervure (69') étant disposée de telle sorte que le corps de valve (65) est déverrouillé par le mouvement de basculement de la partie supérieure (70) du corps de valve (65), et qu'après la suppression du verrouillage, la pression du produit agissant dans la double paroi (72) et la force de rappel de la région comprimée (66) déplacent le corps de valve (65) pour libérer l'ouverture d'évacuation (63).
  12. Tête de diffusion (1, 20, 40, 60) selon une des revendications 3 à 11,
    caractérisée en ce que
    l'élasticité de l'élément de rappel élastique (6, 26, 46, 66) est déterminée, par l'utilisation d'un matériau élastique approprié, par exemple un élastomère thermoplastique (ETP), de telle sorte qu'elle permet un mouvement relatif limité entre la tête de valve (7, 27, 47, 67) et l'ouverture d'évacuation (3, 23, 43, 63).
