Definitions

  • the invention relates to a foam head for a manually operated pressure vessel with a dispensing valve, on the tubular valve stem with a foam head tubular outlet nozzle for actuating the dispensing valve is attachable, with an outlet channel through the Exhaust pipe extends through and with at least one Exhaust opening of the foam head communicates with open dispensing valve with the interior of the pressure vessel connected is.
  • Such a foam head is known from EP 0 581 158 A2.
  • Document WO-A-94/27890 also discloses a foam head according to the preamble of claim 1.
  • the well-known foam head has the disadvantage that the Outlet opening concentric to the longitudinal center axis of the Foam head or the outlet nozzle is formed, the exit plane defined by the exit opening itself extends perpendicular to the longitudinal central axis mentioned, which with the Longitudinal center axis of the pressure vessel coincides. This will when actuating the dispensing valve, the outlet level into a Position shifted obliquely to the longitudinal center axis of the pressure vessel with the result that this must be tilted so that the Exit plane is again approximately parallel to the surface extends to which the container medium is applied.
  • the formation of a shapely pile of foam possible. Also, only then is it safely avoided, for example when forming a pile of foam on the palm of the User foam reaches beyond the palm of the hand and is sprayed on the floor or the like
  • outlet opening it is also important to design the outlet opening so that a particularly voluminous pile of foam can be formed.
  • EP 0 581 158 A2 suggested the outlet opening in the form of evenly Outlet slots distributed over the circumference train that in a particular embodiment concentric within a pot-like recess of the Foam head arranged and directed radially outwards are. This construction is very technical complex.
  • EP 0 452 208 A1 proposes the outlet opening through a sieve plate to define a voluminous Get Foam Pile.
  • the known construction is relative complex, since it is made up of several parts.
  • the present invention is based on the object known foam head to improve that Using this foam head handling the Overall arrangement including pressure vessel becomes more consumer-friendly, and that with comparatively simple means a particularly voluminous and shapely pile of foam can be produced.
  • the one defined by the outlet gap preferably closes Exit plane with the longitudinal center axis of the foam head one An angle of about 40 to 75 degrees, especially about 70 degrees.
  • the outlet gap is preferably also along the circumference variable depth, being in the area or near the maximum gap depth the at least one outlet opening flows, in or near the slit floor.
  • the bottom extends of the outlet gap approximately perpendicular to the longitudinal center axis of the Foam head.
  • the exit gap is approximately oval in shape, the small axis in one through the longitudinal center axis of the foam head plane lying through it, while the major axis lies in one is at a distance from the longitudinal center axis of the foam head and lies parallel to it and approximately extends perpendicular to the longitudinal center axis of the foam head.
  • the small axis closes with the longitudinal center axis of the foam head an angle of about 40 to 75 degrees, especially about 70 Degrees, a.
  • This angle corresponds to the inclination of the gap exit plane opposite the longitudinal center axis of the foam head or in the closed position of the dispensing valve relative to the Longitudinal center axis of the pressure vessel, which is usually in Closed position of the dispensing valve with the longitudinal center axis of the Foam head is aligned.
  • the dimensions of the outlet openings and their placement in or near the bottom of the Exit gap are such that the rate of increase of the in the outlet gap filled medium is such that the medium the gap exit plane at any point of the same to about reached the same time. This means that at every point of the Exit gap about the same amount of foam per unit of time exit.
  • the convenience of the construction according to the invention can be additionally promote that the exit gap comprehensive head wall of the conical upper part of the foam head is spherical on the outside.
  • FIGS. 1-4 and 5-8 each have a foam head 10 shown, the one-piece injection molding process made of plastic is made for a known and therefore not illustrated, manually operated pressure vessel with a Dispensing valve, on the tubular valve stem of the Foam head 10 with a tubular outlet nozzle 12 for Actuation of the dispensing valve can be plugged on.
  • An outlet duct 14 extends through the outlet pipe 12 and stands with 2 outlet openings 11 and 13 of the foam head in connection, the with the interior of the Pressure vessel are connected.
  • the outlet openings 11 and 13 open into an oval circumferential outlet gap 15, namely diametrically away from each other in the direction of arrows 16 and 17 in FIGS. 4 and 8.
  • the exit gap 15 defines one Exit plane 18, which is inclined to the longitudinal center axis 19 of the Foam head 10, which is usually with the longitudinal center axis of the assigned pressure vessel covers, extends.
  • the Outlet connector 12 is in the two embodiments according to the 1-4 or 5-8 of a conical upper part 20 with a on a peripheral edge of the pressure vessel, not shown attachable ring shoulder 21 and one opposite formed head wall 22, in which the outlet gap 15th is formed, this being relative to the longitudinal center axis 19 of the foam head 10 is on one side of the same (see Fig. 4 and 8).
  • On the opposite side is diametrical to Exit gap 15 in the conical upper part 20 of the foam head 10 a finger dent 23 formed.
  • the exit gap 15 comprehensive side of the conical top 20 is by a Film hinge 24 connected to the annular shoulder 21, while the opposite side, which has the finger dent 23 a predetermined breaking web 25 with the annular shoulder 21 in connection stands. If the finger dent 23 by a finger of the user pressed down, d. H. in the direction parallel to Longitudinal center axis 19 in the direction of the annular shoulder 21, breaks first use of the foam head 10 of the predetermined breaking web mentioned 25.
  • the foam head 10 or the conical Upper part 20 of the same including outlet pipe 12 in one position tilted in which the oblique to the longitudinal center axis 19th Extending exit plane 18 of the exit gap 15 almost perpendicular to the longitudinal center axis 19 in its original Starting position extends. At least the exit level 18 arrives in a position in which the angle ⁇ , the exit plane 18th with the longitudinal center axis 19 in its original Starting position includes, is larger and in extreme cases is 90 degrees. This means that when the tilting as intended Foam head 10, the exit plane 18 of the exit gap 15 gets into a user-friendly dispenser position.
  • the outlet gap is 15 in both embodiments with variable over the scope Depth, being in or near the maximum Gap depth the two outlet openings 11 and 13 in the Exit gap 15 open, in the gap floor 26.
  • This Slit floor 26 also extends approximately perpendicular to Longitudinal center axis 19 of the foam head 10.
  • the gap exit plane 18 closes with the longitudinal center axis 19 of the Foam head 10 an angle ⁇ of about 40 to 75 degrees, especially about 70 degrees. This means that with one Tilting the foam head 10 by exercising corresponding pressure on the finger dent 23 by about 20 degrees the gap exit plane 18 is approximately perpendicular to original position of the longitudinal center axis 19 extends.
  • the outlet gap is 15 in Top view oval-shaped, the small one Axis 27 in a by the longitudinal center axis 19 of the Foam head lies through the plane while the major axis 28 at a distance from the Longitudinal center axis 19 of the foam head (see Fig. 4) or at asymmetrical design of the exit gap according to Fig. 8 through the longitudinal center axis 19 of the foam head 10 and lies parallel to it and approximately perpendicular to the longitudinal center axis 19 of the foam head 10 extends.
  • the outlet openings 11 and 13 open in the area of maximum gap depth diametrically away from each other such that first the areas with a smaller to minimal gap depth filled with the container medium, especially foam medium before this medium in the area of maximum gap depth increases. This ensures that the scope of the Exit gap 15 or the associated exit level 18 approximately uniform exit of the container medium takes place.
  • the head wall comprising the outlet gap 15 22 of the conical upper part 20 is convex on the outside, as can be seen very well in FIGS. 3 and 7.
  • the lid 30 is with its peripheral edge on the ring shoulder 21 of the foam head 10 snapped on. It is about this a known construction.
  • the two differ primarily Embodiments only in aesthetics. This is especially true for the finger dent 23 and the exit gap 15, which in Top view is almost kidney-shaped.
  • the finger dent 23 in the embodiment according to FIGS. 5 to 8 is stronger highlighted than in the embodiment of FIGS. 1 to 4.
  • the stronger emphasis of the finger dent 23 results in the embodiment according to FIGS. 5 to 8 primarily in that it is laterally opposite the outer wall of the Upper part 20, which surrounds the outlet pipe 12, a little more emphasized is discontinued.
  • the peripheral wall of the finger dent 23 does not go as in the embodiment of FIGS. 1 to 4 integral in the outer wall of the conical upper part 20 over. Functional this however results for the two embodiments no differences.
  • the finger dent 23 a corresponding Recess 32 in the conical upper part 20 is assigned so that the finger dent 23 is easily accessible from above.
