Definitions

  • the invention relates to a liquid dispenser for dispensing pharmaceutical or cosmetic liquids or liquids from the food sector.
  • a generic liquid dispenser is equipped with a liquid reservoir in which the liquid is stored before it is discharged, with an outlet channel through which the liquid can be discharged to an environment, and with a pump chamber, which, starting from an initial state with maximum pump chamber volume, is manual pump actuation can be volumetrically reduced by means of an actuation handle.
  • an inlet valve arrangement is provided between the liquid reservoir and the pump chamber, which opens under pressure control when there is a negative pressure in the pump chamber compared to the liquid reservoir.
  • an outlet valve arrangement is provided between the pumping chamber and the discharge opening.
  • Generic dispensers are widely known from the prior art. They have a pump that includes the pump chamber, the inlet valve arrangement and the outlet valve arrangement and that allows liquid to be discharged by means of an actuating handle that can be actuated manually.
  • liquid is understood to mean not only low-viscosity liquid media but also pasty media.
  • the liquid dispensers of the generic type, on which the invention is based are mobile liquid dispensers with a liquid reservoir of usually less than 200 ml, which are usually designed as disposable dispensers and are sold together with the liquid to be discharged through them.
  • the pumping devices of known generic dispensers usually have inlet and outlet valve arrangements, each of which operates under pressure control.
  • An excess pressure in the liquid reservoir compared to the pump chamber leads to the inlet valve arrangement opening, so that the liquid can flow into the pump chamber.
  • Excessive pressure in the pumping chamber relative to an atmosphere surrounding the dispenser opens the outlet valve assembly so that liquid can be dispensed.
  • the pump chamber is reduced in size, as a result of which the inlet valve arrangement closes and the outlet valve arrangement opens in the type of dispenser mentioned.
  • With the subsequent enlargement of the pump chamber in the course of a return stroke movement and thereby The resulting negative pressure opens the intake valve assembly and the exhaust valve assembly closes. Liquid is drawn from the liquid reservoir into the pump chamber for the next discharge process.
  • the US6406207B1 discloses a dispenser having a bell-shaped pumping chamber which is slotted to form an outlet valve.
  • the outlet valve can be opened by means of liquid pressure.
  • Further designs of dispensers with outlet valves that open for the purpose of dispensing liquid are given in the documents WO 2012/165727 A1 , WO 2004/004921 A1 and DE 3909633 A1 refer to.
  • a liquid dispenser with a trigger which has a pressure-dependent opening outlet valve with an elastic valve flap.
  • This pressure-dependent opening outlet valve is in a secured state when the trigger is not pressed, in which the liquid cannot reach this outlet valve.
  • An elastic component, on which the valve flap is also provided, is only displaced when the trigger is actuated, so that liquid can flow to the valve flap and deflects it there with sufficient pressure, thus opening the outlet valve.
  • the object of the invention is to further develop a liquid dispenser of the generic type in such a way that it has improved protection against leakage.
  • the outlet valve arrangement comprises a switching valve and a pressure relief valve, the switching valve being independent of the liquid pressure in the pump chamber is mechanically positively opened in response to a displacement of the actuating handle and the pressure relief valve opens in a pressure-controlled manner when there is an overpressure in the pump chamber compared to the outlet channel.
  • the outlet valve arrangement is opened in the manner of a forced opening, which means that the displacement of the actuating handle causes the outlet valve arrangement to open regardless of the pressure existing in the pump chamber.
  • the actuation of the actuating handle thus fulfills a dual function, namely on the one hand the aforementioned volumetric reduction in the pumping chamber and on the other hand the pressure-independent positive opening of the outlet valve arrangement by opening the switching valve.
  • the outlet valve arrangement is designed in such a way that, at least up to a limit overpressure, the outlet valve arrangement does not open solely as a result of overpressure in the pump chamber.
  • the outlet valve arrangement is therefore designed according to the invention in such a way that it prevents opening when the actuating handle is not actuated.
  • Such an outlet valve arrangement which cannot be opened solely by excess pressure in the pump chamber or can only be opened when a considerable excess pressure is reached, prevents an unwanted discharge process from occurring if an excess pressure in the pump chamber compared to a environment exists.
  • the switching valve is designed in such a way that it is pressed in the direction of its closed position by excess pressure in the pump chamber, so that an unintentional pressure-dependent opening cannot take place without destroying the dispenser.
  • a particularly preferred embodiment of the switching valve of the outlet valve arrangement provides that this switching valve has a first sealing surface which is forcibly coupled to the actuating handle, in particular connected in one piece, and has a second sealing surface which is movable relative to this first sealing surface and bears against the first sealing surface in the closed state of the outlet valve arrangement.
  • the second sealing surface can be moved relative to the first sealing surface and can be pushed by moving the actuating handle onto an opening area adjacent to the first sealing surface, which is designed in such a way that it prevents the first sealing surface from coming into close contact with the second sealing surface.
  • the switching valve is thus designed in the manner of a slide valve.
  • the second sealing surface is displaced on the first sealing surface until, in the opening area adjoining the first sealing surface, it necessarily separates from the first sealing surface, at least in sections, in such a way that liquid can flow through between the first sealing surface and the second sealing surface.
  • a particularly advantageous embodiment of this provides that in the opening area, which adjoins the first sealing surface, a ramp-like web or several spaced-apart ramp-like webs is or are provided, onto which the second sealing surface is pushed, so that on both sides of this web a separation of the both sealing surfaces takes place.
  • This ramp-like web is preferably provided with one or more points of interruption, at which a separation of the second sealing surface from the contact with the opening area is forced.
  • the component on which the first sealing surface is provided and the component on which the second sealing surface is provided are connected to one another via a spring element which is tensioned when the second sealing surface is transferred into the opening area .
  • the spring element can be a separate spring element such as a helical spring.
  • the spring element is preferably an elastically formable section which is formed in one piece with the second sealing surface and which is supported on the component on which the first sealing surface is provided, in particular on the actuating handle.
  • the spring element can therefore in particular be formed as a circumferential deformable web on the outside of a pump wall body.
  • the outlet valve arrangement in addition to the switching valve provided according to the invention, also has a separate overpressure valve which opens under pressure control when there is an overpressure in the pump chamber compared to the outlet channel.
  • the outlet valve arrangement thus has two separate valves which are provided in series one behind the other between the pump chamber and the discharge opening. In order for a discharge process to take place, both the switching valve and the pressure relief valve must be opened.
  • This design with a separate pressure relief valve is advantageous above all because this pressure relief valve closes immediately during the return stroke of the actuating handle after a discharge process has taken place when the pump chamber volume increases again. Thus, the suction process taking place in the pump chamber during the return stroke is not delayed by the fact that the switching valve does not close immediately.
  • the second sealing surface of the switching valve is formed in one piece around at least one sealing surface of the pressure relief valve.
  • a common, preferably elastically deformable component is therefore provided, which sealing surfaces of both separate valves provides.
  • the pump chamber has a flexible wall that allows its volumetric variability.
  • This wall surrounds the pumping chamber. It is preferably an essentially rotationally symmetrical component which is open at both ends. Said second sealing surface of the switching valve and/or said sealing surface of the overpressure valve can advantageously be formed in one piece with this wall.
  • a particularly advantageous design of the liquid dispenser can thus be achieved in which the entire outlet valve arrangement, including the switching valve and the pressure relief valve, is formed jointly by the component that also forms the wall of the pump chamber on the one hand and the actuating handle on the other.
  • the component forming the wall of the pump chamber can also act as a return spring of the liquid dispenser at the same time.
  • the pump chamber wall is designed to be closed all the way around and has a substantially cylindrical first section at a first end with an outer diameter that is smaller than the inner diameter of a substantially cylindrical second section at an opposite second end, wherein the pump chamber wall is deformed in the actuated state of the actuating handle in such a way that the first section is surrounded by the second section.
  • Such a pump chamber wall has an approximately cup-shaped shape when the actuating handle is not actuated.
  • the second end which is larger in terms of diameter, is pushed over the first end and overlaps it in relation to the direction of compression of the pumping chamber wall.
  • a connection area that connecting the cylindrical sections of different diameters preferably acts as an elastically deformable spring element for the purpose of resetting. This connection area is preferably designed with thinner walls than the cylindrical areas.
  • An advantageous design of a liquid dispenser according to the invention provides that the actuating handle is operatively coupled to the pump chamber and the switching valve in such a way that when the actuating handle is actuated, the switching valve is first opened and then the pump chamber is reduced in size.
  • Figures 1a to 1c an embodiment of a dispenser according to the invention in the unactuated, partially actuated and actuated state.
  • the exemplary embodiment described below represents a liquid dispenser which can have different types of liquid reservoirs. Since the design according to the invention is particularly advantageous in the case of liquid reservoirs designed as tubes, such tube-like liquid reservoirs are named below. However, this is to be understood as an example.
  • the dispenser described below has a discharge head which is attached to this tube or some other liquid reservoir and which has a volumetrically variable pump chamber which can be reduced in size by moving an actuating handle relative to an associated base in order to discharge liquid.
  • a volumetrically variable pump chamber which can be reduced in size by moving an actuating handle relative to an associated base in order to discharge liquid.
  • the Figures 1a to 1c show an embodiment of a dispenser according to the invention.
  • the exemplary tube-like liquid reservoir 12 of this dispenser is only partially shown.
  • the discharge head 20 of the dispenser consists of only three components, namely a base 30, an actuating handle 40 with a discharge opening 42 and an intermediate pump chamber component 50.
  • a riser pipe which is preferably provided in dispensers according to the invention and extends into the liquid reservoir 12.
  • the actuating handle 40 comprises a pressure surface 43 and a lateral surface 44 projecting downwards therefrom. Together with an inner and an outer circumferential guide web 31, 32 on the side of the base 30, this lateral surface 44 forms a guide along which the actuating handle 40 can be moved in the direction of arrow 2 is relocatable.
  • the pump chamber component 50 arranged between them is made of an elastically deformable material such as an elastomer.
  • the pump chamber component 50 has an essentially rotationally symmetrical shape and is designed to be open at its lower end 50b and at its upper end 50a. Holding sections 51a, 51b are provided at both ends 50a and 50b, by means of which the component 50 is fastened to the base 30 on the one hand and to the actuating handle 40 on the other hand. The pump chamber component 50 is therefore compressed in the direction of arrow 2 when the actuating handle 40 is pressed down.
  • the component 50 has a cup-like shape, which has two approximately cylindrical portions 52a, 52b and a connecting portion 52c therebetween.
  • the wall thickness of the component is reduced in the connection area 52c compared to the average wall thickness in the cylindrical areas 52a, 52b.
  • the connection area 52c acts as a spring during operation, as will be explained below.
  • the pump chamber component 50 surrounds a pump chamber 60 of the dispenser, which is volumetrically reduced in accordance with the purpose for dispensing liquid.
  • an inlet valve arrangement 70 and an outlet valve arrangement 80 are provided, which are arranged on the inlet side and outlet side of the pump chamber 60 .
  • the inlet valve arrangement 70 has an inlet valve, which is formed by a valve lip 72 and a mating surface 74 provided on a central pin. This inlet valve opens as a function of the differential pressure between the pump chamber 60 and the liquid reservoir 12. If there is a vacuum in the pump chamber 60 during the return stroke, the inlet valve opens and allows liquid to flow into the pump chamber 60.
  • the valve lip 72 is designed in one piece with the pump chamber component 50 .
  • the outlet valve assembly 80 is more complex and in Figure 1a therefore shown enlarged again. It comprises an outlet valve 82 which also opens as a function of the pressure and has a sealing lip 82a and a counter surface 82b which is provided on a collar-like web 46 which is provided in one piece on the actuating handle 40 .
  • a switching valve 84 is part of the outlet valve assembly.
  • This switching valve 84 has a valve lip 84a which, like the valve lip 82a, is provided in one piece on the pump chamber component 50. It also has a cylindrical mating surface 84b, which is arranged on the outside of the valve lip 84a and is an integral part of the actuating handle 40.
  • This switching valve 84 is closed when the dispenser is not actuated.
  • the sealing lip 84b rests circumferentially on the counter surface 84a from the inside.
  • the switching valve 84 cannot be opened by an increase in pressure in the pump chamber 60 either, since such an increased pressure, for example achieved by compressing the tube 12, can open the inlet valve arrangement 70 and the pressure relief valve 82, but the pressure can still seal the switching valve 84 amplified instead of opening this valve as well.
  • the higher the pressure in the pump chamber 60 and beyond the pressure relief valve 82 the stronger the valve lip 84b is pressed against the counter surface 84a.
  • Fig. 1b and 1c Based on Fig. 1b and 1c is clarified as per the donor Fig. 1a functions. Is based on the state of Fig. 1a If the actuating handle 40 is pressed downwards in the direction of the arrow 2a, this is inevitably accompanied by a deformation of the pump chamber component 50. However, the pump chamber component 50 is initially only deformed to a small extent, since the upper end of the component 50 beyond the upper holding section 51a can dip deeper into the actuating handle 40, with elastic deformation of a circumferential spring area 53 on the inside of the upper holding section 51a.
  • valve lip 84b This also results in a corresponding relative movement between the valve lip 84b and the mating surface 84a in the state of Fig. 1b .
  • the sealing lip 84b is pushed onto an opening portion 84c on the side of the operating handle 40, which is on the opposite surface 84b connects.
  • this opening area 84c there is a bevel 84d with multiple interruptions, which is positioned opposite to the direction of the arrow 2a and which is not provided all the way round, but rather has an interruption 84e on the left-hand side in relation to the illustrations.
  • the bevel 84d and the interruption 84e ensure that it is no longer possible for the valve lip 84a to lie tightly all around.
  • the valve lip 84a separates from the actuating handle 40 at least in the area of the interruption 84e.
  • the pump chamber component 50 is then clearly deformed.
  • the upper cylindrical area 52a is pushed over the lower cylindrical area 52b with increasing elastic bending and stretching deformation, particularly in the connecting area 52c.
  • the internal volume of the pump chamber is reduced in the process, so that medium that is under overpressure therein is discharged along the path 8 .
  • the pressure relief valve 82 closes immediately, so that a negative pressure is created in the pump chamber 60, which is suitable for sucking in new medium from the liquid reservoir 12.
  • the spring force from the spring area 53 ensures that the sealing lip 84b of the switching valve 84 is also pushed back again, so that towards the end of the return stroke it again rests sealingly against its counter surface 84a.
