Definitions

  • the invention relates to a discharge head for a dispenser and a dispenser with such a discharge head.
  • a generic discharge head comprises a housing with a coupling device for coupling to a reservoir which is used to receive a liquid or pasty medium, an inlet opening facing the reservoir and a discharge opening for discharging the medium into a surrounding atmosphere, a conveying device for conveying the medium from the Inlet opening to the discharge opening and an actuating handle for actuating the conveyor device, which can be moved manually with respect to the housing.
  • Such discharge heads and dispensers with such discharge heads are generally known from the prior art. They are used to dispense pharmaceutical media. In particular, they are also used to dispense cosmetic creams, lotions and other cosmetic media.
  • the object of the invention is to provide a discharge head which combines high reliability with a simple form of manufacture. It is also a task to provide a dispenser with such a discharge head.
  • a discharge head within the meaning of the invention is that part of a dispenser which is coupled to the preferably bottle-like reservoir in order to allow the dosed discharge of the medium stored in the reservoir.
  • the housing of the discharge head is that part which at least provides the coupling device by means of which the discharge head is connected to the reservoir.
  • the coupling device of the housing surrounds at least the named inlet opening, for example a connecting piece which is provided for attaching a riser pipe which serves the purpose of guiding medium from the reservoir into the discharge head for the purpose of discharge.
  • the discharge head comprises the said conveying device, which can be designed, for example, as a piston pump.
  • the conveying device is actuated by means of the actuating handle, which is movable relative to the housing and thus at least relative to the coupling device of the discharge head and serves the purpose of effecting a discharge process caused by the conveying device by applying a manual force.
  • the invention relates to a generic discharge head in which a one-piece component is provided, which is made as an injection-molded part from two plastics with different properties, this component being the actuating handle and / or a piston of the conveyor on the one hand and one between the actuating handle or the piston and the Housing spring acting as a return spring on the other hand forms.
  • a one-piece component is provided, which is made as an injection-molded part from two plastics with different properties, this component being the actuating handle and / or a piston of the conveyor on the one hand and one between the actuating handle or the piston and the Housing spring acting as a return spring on the other hand forms.
  • At least the guide surface provided on the actuating handle for guiding the same or a sliding sealing surface of the piston for interacting with a cylinder of the conveying device is made from a first of the two plastics and the spring is made from a second of the two plastics.
  • the first plastic is preferably a harder plastic with a higher modulus of elasticity and the second plastic is a softer plastic with a lower modulus of elasticity and good elastic properties.
  • the softer plastic is in particular TPE (thermoplastic elastomers).
  • the harder plastic is preferably polypropylene or HDPE (high density polyethylene).
  • the actuating handle and the return spring provided for resetting the actuating handle are thus formed in one piece with one another, which in turn enables easier assembly, since the easily deformable and therefore difficult to handle spring does not have to be handled separately during assembly. Instead, they are handled jointly with the actuating handle, which is at least partially relatively rigid, or the piston, which is at least partially relatively rigid.
  • the spring can be designed as a helical spring. However, it can also be designed as a closed bellows-like spring.
  • the second of the named plastics, from which at least the return spring is made is also used on an outer surface of the actuating handle. This allows a so-called soft-touch surface to be generated, which is felt to be particularly pleasant to the touch.
  • the spring provided on the inside of the actuating handle and the soft-touch surface provided on the outside of the actuating handle is directly connected to one another, in particular in that a base body of the actuating handle made of the first plastic has openings through which the second plastic extends. This makes the injection molding process easier because the softer plastic only has to be fed in at one point.
  • the invention further relates to a dispenser with a preferably bottle-like reservoir and a discharge head, the discharge head being designed in the manner described.
  • FIGS. 1 and 2 show an embodiment not according to the invention of a discharge head 10, which is provided for attachment to a liquid reservoir 8 indicated by dashed lines.
  • the discharge head 10 has a housing 20 as well as an actuating handle 80 which is movable in an actuating direction 2 in comparison.
  • an inlet opening 22 is provided on the side of the housing 20 facing the liquid reservoir 8, which is passed through a riser pipe provided nozzle is formed.
  • a liquid channel 24 extends from this into a pump chamber 26 which can be changed volumetrically by moving the actuating handle 80 relative to the housing 20.
  • both the housing 20 and the actuating handle 80 have approximately cylindrical walls 28, 82 which rest against one another in a radially sealing manner and form walls of the pumping chamber 26.
  • a discharge channel 30 connects to the pump chamber 26 and opens into a discharge opening 32.
  • a two-component injection-molded valve component 70 is provided on the housing 20, which provides both an inlet valve 72 and an outlet valve 74.
  • the inlet valve 72 opens when there is a negative pressure in the pump chamber 26 with respect to the liquid reservoir 8.
  • the outlet valve 74 opens when there is overpressure in the pump chamber with respect to a surrounding atmosphere.
  • a conveying device is thus formed which, when the actuating handle 80 is pressed down, discharges medium from the pump chamber 26 and sucks in medium from the medium reservoir 8 while it is pressed down.
  • a coil spring 90 made of plastic is provided between the housing 20 and the actuating handle 80 and can press the actuating handle and thus also the cylinder surface 82 in direction 2a, that is to say in the direction of its starting position.
  • This spring is designed in such a way that in the inoperative state of the Figs. 1 and 2 is completely relaxed, whereby relaxation processes in the material of the spring are avoided.
  • the spring 90 is elastically compressed only when the actuating handle 80 is actuated.
  • That component 20 which forms the housing also forms, in particular, a coupling device 40 of this housing 20 in the form of an internal thread, by means of which the discharge head 10 is coupled to the liquid reservoir 8.
  • a further essential part of the one-piece housing 20 is a section 50 surrounding the inlet connector 22, which is formed in one piece with the other components of the housing 20, but at least compared to the coupling device 40 is made of a softer and more flexible plastic.
  • This section 50 fulfills two functions. On the one hand, it forms a sealing ring area 52 resting on the bottle neck of the liquid reservoir 8, which is compressed by screwing the discharge head 10 onto the liquid reservoir 8 and thus prevents liquid from escaping in this transition area.
  • the section 50 forms a bell-shaped ventilation valve 54 which has a slot-like opening 54a. The purpose of this venting valve 54 is to allow air to flow in when there is negative pressure in the reservoir, which is generated by discharging liquid. The valve 54 prevents the corresponding path of the air, which is illustrated by the dashed line 4 in the opposite direction, from inadvertently allowing the escape of liquid.
  • the ventilation valve 54 opens only when there is negative pressure in the liquid reservoir 8.
  • the housing 20 including the section 50 is produced as a one-piece component from two different plastics in multi-component injection molding, in this case from TPE for the section 50 and PP or HDPE for all other sections.
  • This one-piece design facilitates assembly.
  • the number of those contact points between components at which liquid can escape from the liquid reservoir 8 in an improper manner is reduced.
  • the discharge head 110 of the Figure 3 differs from the embodiment of FIG Figures 1 and 2 .
  • the section 50 is not connected in one piece to the housing 20 in this embodiment. Instead, it forms a separate component made of a uniform, soft plastic, in particular made of TPE, which is arranged in a depression 20a of the housing 20 that is open at the bottom and is held here with a force fit.
  • this section 50 in turn includes both a sealing ring area 52 and a ventilation valve 54, each of which is constructed in such a way as the Figs. 1 and 2 demonstrate. Even if the section 50 is not an integral part of the housing 20, the integration of the sealing ring and the ventilation valve in one component can achieve a considerable simplification of assembly. Nevertheless, it can of course also be used in the design of the Fig. 2 a cohesive one-piece design of the housing 20 and of the section 50 can be provided.
  • the return spring 92 and the actuating handle 80 are provided as a common one-piece component. These are also produced in the manner already described by two-component injection molding. While the cylindrical outer wall 84 as well as the cylindrical wall 82 belonging to the conveyor device and an end face 86 connecting these cylindrical walls 82, 84 are made of a hard plastic, in particular of PP or HDPE, the restoring spring 92, which is designed in the form of a bellows as an example, is made of a softer and Formed plastic that is well suited for resetting, in this case, for example, from LDPE. The assembly of the actuating handle 80 with the integrally formed return spring 92 is facilitated by the combination in a common component.
  • a particular advantage results from the fact that the material of the return spring 92 is also used on an outer side 88 of the actuating handle 80. This outer side 88 is directly connected to the return spring 92 via openings in the end face 86.
  • the use of the soft, elastic material also on the outside 88 gives a very pleasant haptic impression during actuation.
  • the entire discharge head 110 of Figure 3 thus consists of only four components to be joined together during assembly, namely the housing 20, the sealing and valve section 50, the valve unit 70 and the actuating handle 80 with an integrally formed return spring 92.
