Definitions

  • the invention relates to a device for spraying a liquid from a container, with a piston pump, the housing of which can be locked in a liquid-tight manner in a container opening and the delivery chamber of which is connected via a suction valve and a suction pipe directly to the lower part of the container chamber in the normal position and via a piston and axially penetrating the piston rod;
  • Outlet channel can be connected to the outside, a secondary channel leading from an upper part of the container space in the normal position to the suction opening of the suction valve and a gravity-operated auxiliary valve is formed in the secondary channel, which shuts off the secondary channel in the normal position of the container.
  • the preferred field of application of such a spray device is cosmetic and pharmaceutical products.
  • the secondary channel runs through a bore in the auxiliary valve housing above the auxiliary valve space and a bore in the bottom of the auxiliary valve space.
  • auxiliary valve chamber is chosen to be substantially larger than that of the closure piece, this not only leads to a higher material expenditure, but also complicates the implementation of the spraying device through the container opening during assembly.
  • the invention has for its object to provide a device of the generic type, which also allows spraying of the container liquid in the top of the container, but with less material, manufacturing and assembly costs.
  • this object is achieved in that an opening in the wall of the auxiliary valve chamber in the head overlay is released due to the gravity actuation of the auxiliary valve.
  • the liquid in the head overlay of the container flows freely above the closure piece, without the closure piece being brought into the closed position by the flow pressure that it occupies in the normal position.
  • the dimensions of the auxiliary valve can therefore be chosen freely and relatively small, so that it can also be mounted in the container with the spray device.
  • a second auxiliary valve is omitted, which further simplifies the material expenditure and the assembly.
  • an auxiliary valve housing which is separate from the pump housing is arranged between the pump housing and the suction pipe and a connecting piece is formed on the pump housing.
  • this connecting piece can form the suction valve housing and project into the auxiliary valve housing in addition to the auxiliary valve.
  • an outer part of the pump housing is formed in one piece with the auxiliary valve housing, that the suction valve chamber and the auxiliary valve chamber lie next to one another, that the auxiliary valve chamber is covered by an insert which is formed in the outer pump housing part and which coincides with the suction valve chamber connects the delivery chamber of the piston pump.
  • auxiliary valve housing lies within the cross-sectional contour of the pump housing. This allows the use of containers with a relatively small inner diameter of their neck opening because the spraying device has a correspondingly small outer diameter.
  • the insert is provided with a hollow extension which forms the suction valve housing, the insert and the suction valve can be easily preassembled before installation in the pump and auxiliary valve housing.
  • the approach of the insert can be inserted into a corresponding hole in the auxiliary valve housing part, which at the same time forms part of the main and secondary channel for the dispensing.
  • the suction valve chamber and the auxiliary valve chamber each have an upper opening in the normal position through which the liquid is sucked through.
  • these openings are preferably designed for insertion of the respective valve closure piece, the insertion opening of the suction valve chamber being partially closed by the insert can be.
  • the closure pieces can be inserted into the respective valve chamber in a simple manner and secured therein by the insert without the connection between the pump delivery chamber and the suction valve chamber being interrupted.
  • the auxiliary valve closure piece is a ball
  • the ball diameter can be larger than the smallest radial width of the space accommodating the suction valve. This facilitates the assembly of the auxiliary valve plug. It is always inserted in the correct position in the auxiliary valve chamber without the risk that it will be introduced into the space for which the suction valve is intended.
  • auxiliary valve housing 4 with an auxiliary valve 5 and from one to the bottom of the container reaching intake manifold 6 (also called dip tube).
  • the piston pump 2 has a piston 7 with a piston shaft 8, a housing 9 forming the cylinder for the piston with a lower connecting piece 10, a suction valve 11 formed in the connecting piece 10 and a spring 12 between the piston 7 and the bottom of the delivery space 13 of the piston pump 2. Except for the spring 12, all pump parts are made of thermoplastic.
  • the piston shaft 8 has an axial bore 14, which continues as a bore 15 in the spray head 1.
  • a radial bore 16 extends from this bore 15 into the open. The diameter of the bore 16 is so small that the liquid emerging from the delivery chamber 13 when the spray head 1 and thus the piston 7 are depressed is sprayed via the outlet channel formed by the bores 14 to 16.
  • the piston shaft 8 is guided in an upper opening 17 of the hood 3 and is seated firmly in a bore 18 of the spray head 1.
  • the suction valve 11 consists of a valve closure piece in the form of a ball 19 and a conical valve seat 20.
  • the valve chamber 21 is connected to the delivery chamber 13 of the piston pump 2 through an opening 22.
  • Resilient, flexible projections 23 allow it to pass through press the ball 19 through the opening 22 during assembly and the flow of the liquid sucked in by the piston 7, but prevent the ball 19 from escaping from the valve chamber 21 by itself.
  • valve chamber 21 is connected via an opening 24 coaxially through the valve seat 20 to a housing chamber 25, in which the connecting piece 10 is sealed and which in turn is connected via an opening 26, a connecting piece 27 on the underside of the auxiliary valve housing 4 and the suction pipe 6 received by the connecting piece 27 is connected to the lower part of the container space in the normal position of the liquid container.
  • the auxiliary valve 5 has a closure piece in the form of a ball 28 and a conical valve seat 29 which interacts with it.
  • the ball 28 is located in a valve chamber 30 formed in the auxiliary valve housing 4, which has an upper opening with a radially inwardly projecting annular circumferential elastic projection 31, which has a similar function to the projections 23, and a lateral opening in the form of a Has outer wall of the valve chamber 30 penetrating axial slot 32. Then the valve chamber 30 is lifted from the valve seat 29 ball 28 via an opening 33 passing through the valve seat 29, the opening 26, the connecting piece 27 and the suction pipe 6 also with the top in the head overlay of the liquid container and via the slot 32 with the connected to the head part of the lower part of the liquid container space.
  • a radially inwardly projecting rib 34 in the connecting piece 27 prevents the suction pipe 6 from being inserted into the connecting piece 27 during assembly and against the lower edge of the opening 33 and interrupting the connection to or from the valve chamber 30.
  • the spray head 1 and thus the piston 7 are first pressed down against the force of the spring 12.
  • the ball 19 is pressed against the valve seat 20 so that the suction valve 11 is closed and the air contained in the delivery chamber 13 is displaced into the open via the outlet channel 14, 15, 16.
  • the spring pushes the piston 7 upward, so that due to the throttling action of the bore 16 in the delivery chamber 13, a negative pressure is created which lifts the ball 19 from the valve seat 20 and liquid from the lower part of the liquid container chamber via the channel 6, 26, 25, 24, 21, 22 sucks into the delivery chamber 13 of the piston pump 2, the auxiliary valve 5 being closed at the same time. This closing is ensured both by the negative pressure and by the weight of the ball 28. Pressing the spray head 1 or the piston 7 down again causes the suction valve 11 to close and the liquid now contained in the delivery chamber 13 to be displaced into the open via the outlet channel 14, 15, 16 and thereby being sprayed at the outlet end of the bore 16. After releasing the spray head 1, the spring 12 again effects a return piston stroke while the delivery chamber 13 is filled again, so that liquid can be sprayed again with the next actuation stroke.
  • both balls 19 and 28 fall down to the projections 23 and 31.
  • the liquid can now, provided the liquid level is higher than that in this position of the container Lower edge of the opening 26, via the secondary channel formed by the slot 32, the valve chamber 30 and the opening 33 continue to flow via the opening 26, the housing space 25, the opening 24, the valve space 21 and the opening 22 into the delivery space 13 and into the duct section 14, 15, since the air which may be contained in the spaces 21 and 13 escapes through the outlet duct, on the other hand, the liquid is prevented from escaping through the throttling bore 16 under normal pressure.
  • a sealing ring 47 which is supported by an intermediate ring 48 on the underside of the hood upper part, ensures a seal between the upper edge of the container opening and the screwed-on spray device.
  • the upper part of the exemplary embodiment according to FIG. 2 does not differ from that according to FIG. 1. This part is therefore not shown in FIG. 2.
  • the difference from Fig. 1 is essentially only that the connecting piece 10 is not coaxially, but eccentrically attached to the pump housing 9, eccentrically by an amount such that the auxiliary valve housing 4 lies within the circumferential contour of the pump housing 9 .
  • This spray device is therefore suitable for liquid containers with a smaller inner diameter or opening.
  • FIG. 3 differs from that of FIG. 2 in that the outer part 9a of the pump housing is formed in one piece with the auxiliary valve housing 4 and the remaining part 9b as an insert. In this way, a projection 31 in the insertion opening 37 of the auxiliary valve chamber 30 can be omitted.
  • the diameter of the ball 28 is larger than the smallest width or the inner diameter of the space 25 into which the connecting piece 10 is inserted. The ball 28 can therefore simply be thrown into the housing part 9a during assembly. Nevertheless, it always falls into the auxiliary valve space 30.
  • FIG. 4 differs from that of FIG. 3 only in that the insert 9c has no connection piece 10 and the suction valve 11a is formed in the space 25a of the auxiliary valve housing 4a is.
  • the ball 19a and the suction valve seat 20a are therefore larger, and the opening 24a is formed directly in the auxiliary valve housing 4a.
  • the ball 19a is inserted unhindered through the opening 38 before the insert 9c is inserted.
  • Both balls 19a and 28 are of the same size, so that no distinction is required in the assembly and storage of the ball. Overall, the manufacture is easier.
  • all parts of the spray head and the housing are made of thermoplastic material.
  • the valve closure balls are preferably made of metal.
  • suction pipe 6 can also be pushed outside over the connecting piece 27.
  • a check valve can be provided in the channel 14 or 15, which closes during the suction stroke of the piston 7.
