Definitions

  • the invention relates to a refillable dispensing container for liquid media, in particular an aerosol can, in which a dispensing valve is mounted with housing for dispensing the container contents in a mounted on the upper edge of the container valve plate and in which a filling valve for filling the container by sealingly connecting a filler neck is provided with the container for supplying liquid medium and compressed gas.
  • An output container similar to the type described above is known from EP 0 662 431 known.
  • a dispensing container of the type mentioned which can be refilled after emptying with liquid media, whereby a compressed gas is introduced, which serves as a propellant gas.
  • the filling of the known dispensing container via a filling device with a filler neck, on which the refillable dispensing container is placed.
  • the known dispensing container at its top bottom, the dispensing valve and against this at the bottom of a filling valve, with which the filler neck can be connected by placing the bottom of the filler neck.
  • the invention is therefore an object of the invention to improve the output container of the type described so that it has a simpler structure with fewer items, is more economical to produce and ensures safer operation.
  • the filling valve has at least one attached to the dispensing valve flow hole, which is sealable by a movable sealing member made of elastomeric material.
  • the aerosol cans i. the so-called output container in the description, provided with a valve plate, which is attached to the upper edge of the dispensing container and in which the dispensing valve is attached.
  • the construction of the valve disk and the dispensing valve located centrally in the latter has developed as a unit insofar as the valve disk practically belongs to the dispensing valve and a component, i.
  • the new dispensing container is not only more economical to produce, but it is also safer in operation, because even dirt on the bottom of the container are neither feared nor critical.
  • a refilling of, for example, 400 ml in 8 seconds or less is possible.
  • the performance of the new output container can thus be increased by more than 25% compared to known output containers.
  • the sealing member of elastomeric material is movably adjacent, on or in the flow-through hole, wherein either the pressure or a mechanical part of the filler neck can lift the sealing member off the flow-through or expel therefrom or sealingly engage the flow-through hole.
  • a preferred embodiment of the invention is characterized in that the at least one flow-through hole is located in the housing of the dispensing valve and the movable sealing member has a sealing sleeve surrounding at least the part of the dispensing valve housing having the flow-through hole. If you want the filling with liquid medium and compressed gas in less time, then larger flow channels should ensure their passage, but on the other hand also be well sealed.
  • the flow hole provided according to the invention is located in the housing of the dispensing valve in this embodiment. In other words, all means for a good and fast flow of incoming media are present in the dispensing valve itself, especially here in its housing.
  • the movable sealing member has a sealing sleeve.
  • This surrounds at least that part of the housing of the dispensing valve, which has the flow hole.
  • the sealing collar surrounds the cylinder jacket-shaped part of the housing of the dispensing valve, which has the flow-through, from the outside, so that pressure from outside the sealing sleeve provides a sealing closure of the check valve, while an internal pressure causes an opening, because the sealing collar from the flow-through takes off and releases the latter.
  • the sealing collar can be surrounded by a fixing ring. It is particularly advantageous if the sealing collar is provided to its inner end with a flange-like thickening, whereby a step is formed. Appropriately arranges the fixing ring in this stage and thus holds the sealing sleeve very reliable and yet easy.
  • the dispensing container is like many known spray or aerosol cans a substantially cylindrical, elongated hollow body. It is easy to think through the middle of a longitudinal central axis. The footprint of such a dispensing container (spray can) is to think in a plane which is perpendicular to this longitudinal central axis.
  • the annular surface of the valve disk which encompasses the dispensing valve, runs parallel to this level of support. In this annular surface of the valve disk is sufficient space to arrange one or more fürflußloch / holes.
  • the invention provides for the sealing part to have at least one flow-through pin which penetrates through at least one through-hole and which can be applied in a sealing manner against the edge of the flow-through hole.
  • the flow pin By the example punched or drilled circular flow hole (or through the multiple flow holes) should flow during filling the liquid medium and the compressed gas as long as the sealing member, in this preferred embodiment, the flow pin, the flow hole releases.
  • the flow pin described here for example, it can be wholly or partly pushed out of the respective flow hole, so that liquid and gases can flow through it. If the dispensing container filled with the desired amount of liquid and the compressed gas at the desired pressure, then the flow pin is sealingly applied against the edge of the flow-through hole.
  • the pin then reaches through the hole.
  • the filler neck of the filling device is pressed onto the valve disk, then an edge or pin provided on the filler neck ensures that the flow-through pin made of elastomeric material is again forced out of the throughflow hole for filling.
  • the flow-through pin is articulated to a fixing ring surrounding the housing of the dispensing valve.
  • the fixing ring is suitably made of the same elastomeric material as the flow-through, so that it can be produced correspondingly cheaper with the flow-through pin as a single molded part.
  • the articulation of the flow pin on the fixing ring via a film hinge is expedient if, in a further embodiment of the invention, the articulation of the flow pin on the fixing ring via a film hinge.
  • the flow pin can be fastened or articulated to the fixing ring in different degrees of stiffness.
  • Particularly safe is the penetration of the fixing ring when it rests in a further embodiment of the invention on the inner surface of the annular surface of the valve disk.
  • the sealing member has an annular, the housing of the dispensing valve encompassing flat gasket, which is sealingly above the at least one flow hole.
  • This flat gasket has over the embodiment with the flow pins or the sealing sleeve the further advantage that it needs to be oriented during assembly with respect to the dispensing valve and not even with respect to the valve disk.
  • the flat ring of elastomeric material forming the sealing member need only be placed over the housing of the dispensing valve and pushed up over the housing so that it lies sealingly over the through-hole or over-flow holes.
  • the surface of this gasket is relatively large, and it results from the usual internal pressure, under which the filled, liquid medium is, a good sealing force.
  • a further advantageous embodiment of an embodiment of the invention is characterized in that the flat gasket between the annular surface of the valve disk and a housing surrounding the dispensing valve encompassing fixing ring is arranged.
  • the opening of the latter is predominantly mechanically, for example by depression by means of an edge on the filler neck, it can be the flow hole in the embodiments with the flat gasket and with the sealing sleeve thereby reveal or open that from the filling side a pressure with the liquid medium and / or the compressed gas takes place, which is higher than the pressure in the dispensing container to be filled.
  • the flat gasket or the sealing collar lifts off in the region of the flow-through hole or of the through-flow holes, and the medium can flow into the dispensing container in the desired manner.
  • none of the embodiments described herein does one have to use a special tool to expose or open the flow hole.
  • FIG. 1 shows in cross section the broken off upper part of a refillable dispensing container 1.
  • a valve plate 4 is attached via a seal 3.

  • valve disk 4 engages in the middle of the housing 8 of the dispensing valve 9 and is crimped for attachment to the housing 8 from the outside inwards, as in the Figures 2 and 5a at 16 (Crimpline) is indicated. From this crimping line 16 radially outward, the dispensing valve 9 enclosing annular surface 17 of the valve plate 4 connects. This annular surface 17 is located in a thinking, in FIG. 5a Dashed line indicated plane 18 perpendicular to the longitudinal center axis 5 of the output container. 1
  • the sealing member 15 a in contrast to the second embodiment 15 b of FIG. 5a ) a Quiflußit 15 a ', which passes through the respective flow hole 14.
  • the flow pin 15a ' is in the sealing state against the edge of the flow hole 14 at. This condition can be seen in particular in the FIGS. 1 and 2 , In these and the cross-sectional views of Figures 4c and 4d recognizes the root portion 19 of the flow pin 15 a '.
  • the sealing function is particularly favorable when an O-ring seal 20 surrounds the flow-through pin 15a 'at its root region 19.
  • the flow pin 15a ' is movable relative to the flow hole 14, but on the other hand is hinged to the output valve 9 reproducible, it is provided that the flow pin 15a' is articulated to a fixing ring 21 which surrounds the housing 8 of the discharge valve 9. The articulation takes place via a film hinge 22. While on the fixing ring 21 after the FIG. 4a a single flow pin 15a 'is hinged over the film hinge 22 are in the embodiment of the Figures 4b and 4d four radially outwardly extending film hinges 22 hinged to these outside flow pins 15a '.
  • FIG. 5a shows another preferred embodiment, according to which the sealing member 15b is an annular, the housing 8 of the dispensing valve 9 embracing flat gasket 15b, which according to the left side of the FIG. 5a is above the flow hole 14 and this seals.
  • the housing 8 of the dispensing valve 9 is also surrounded by the interior of the container 1 through a fixing ring 21 '. Between this and the annular surface 17 of the valve disk 4, the flat gasket 15b 'is clamped.
  • FIG. 5b is a similar view in many parts as FIG. 5a Therefore, the matching features and parts will not be described again here.
  • FIG. 5b in the valve disk 4 is not a through hole in the said dispensing valve 9 encompassing annular surface 17 is present. It also lacks the flat gasket 15b, 15b 'and from the bottom outside patch fixing ring 21'. Instead, in the embodiment, the surrounds FIG. 5b the sealing collar 24, the housing 8 of the dispensing valve 9.
  • the sealing sleeve has an axial length which corresponds to almost half the axial length of the housing 8. Therefore, the sealing sleeve 24 also does not project beyond this housing 8.
  • the sealing collar 24 ends in the form of a flange-like thickening 25, through which a shoulder is formed down into the interior of the aerosol can.
  • the fixing ring 21 holds the sealing sleeve firmly on the outer surface of the housing 8.
