    The nebuliser has a hand-operable valve mechanism (11, 12), consisting of a seal (11) which is placed against a membrane (12) in the neutral position, as well as a hood (17). The pressure occurring when the hood is fitted onto the nebuliser head (8) is passed through the spray nozzle (9) and a duct (14) up to the seal (11), raises the latter and thus passes into the interior of the container (1), whereupon the seal (11) immediately closes again. It is only raised again when the nozzle (9) is pressed down after removal of the hood (17) and, in doing so, pushes the tubular section (10) connected to the seal (11) downwards. The pressure in the container (1) can then propel the liquid (2) into a tube (7) and through the latter to the spray nozzle (9) where it is nebulised. In this way, with only one pumping movement a nebulisation is obtained which is maintained until the pressure in the container (1) is reduced. <IMAGE>

    The invention relates to devices for spraying liquids from vessels, preferably cans or bottles.
    It is known a spray device, 5 consisting of a head with a vertical channel formed in it, mounted in its lower part of the valve mechanism with a seal, located above it with the possibility of moving the nozzle with the tube, and the cap 1.
    The advantage of the known device is that it allows jg to use known vessels, for example a bottle that is not a high pressure vessel.
    However, the known device is complicated by its design and does not ensure satisfactory spraying of the liquid during its delivery. In addition, the known device does not provide long-term continuous operation in case of the need of several consecutive liquid feeds. And among other things, the pumping mechanisms of the device can fill the valve and the valves leak. 30
    The purpose of the invention is to simplify the design of the device.
    This is achieved by the fact that in the proposed spray device the cap is mounted with the possibility of reciprocating relative to the head, and between them a sealing ring is located.
    At the same time the sealing ring is mounted on the head,
    In addition, it can be located on the inner cylindrical surface of the cap.
    In addition, the device is equipped with a membrane, hermetically sealed under the channel of the head, having a hole coaxially with them and rigidly connected to the nozzle.
    In addition, the membrane is made of spring material and is mounted for reciprocating movement.
    In addition, the head contains two concentrically mounted one to the other with the formation between them of the chamber section with channels for the passage of air, while the inner section has an elastic shell fixed in its lower part under the channels and enters the inside of the vessel to prevent its contents from connecting to air, and the valve and nozzle are mounted on the outer section. The device is also equipped with a copcentric mounted on the inner cavity of the cap with a tube covering the head. At the same time in the lower part of the tube there is a flange for the bottom of the seal. 1 schematically shows a spray device, a general view; 2-4 shows the dispensing device of FIG. 1 according to the second. an embodiment in three different positions in the process of its operation, in a longitudinal section; 5 - a third embodiment of the spray device, in longitudinal section; on figb and 7 - the Central part of the head of the device according to figure 5,. in a longitudinal section; in Fig. 8 is a longitudinal section enveloping the head with a flange for sealing. The device (figure 1) contains a head 1 with a vertical 2 formed in it, a valve mechanism, a nozzle 3 with a tube 4 and a cap 5. The valve mechanism is mounted in the lower part of the vertical channel 2 of the head and has a seal 6, and the nozzle 3 is located above the vertical the channel 2 is movably connected to the channel 7 of the tube 4 for communicating the channel 8 of the nozzle with the space of the upper part 9 of the chamber 10 enclosed by the seal 6. The lower part 11 of the chamber 10 serves to communicate with the internal cavity of the vessel 12, the vessel 12 is partially filled with liquid,for example, water 13. At the throat of 14 vessels, the following deposits are installed: -: 15 with a protrusion 16 connected to the pipes. The head 1 is screwed onto the throat of the 14 of the vessel 12 with the possibility of sealing the insert 15 located between the head and the vessel. Cap 5.-mounted with the possibility of return-and-translational movement relative to the head 1 and between them is located the sealing ring 18, which serves to prevent air leakage between the inner surface of the cap and the outer surface of the head when created from excessive pressure in the cavity 19 under the cap . The device also contains a membrane 20, which is hermetically mounted on the head 1, under its channel 2, while the membrane 20 is coaxial with no hole (not shown) and rigidly connected to nozzle 3. The membrane 20 is made of spring material and can be mounted on the annular flange 21 of the tube 4 with a possibility of returning to the patient's position. Figures 2 to 4 show the device in which the insert 15, the nozzle 3 and the reinforcement 6 have a different design compared to those shown in Fig.1, the nozzle 3 is located in the upper part of the head 1, and the configuration of the cap 5 corresponds to the shape of opl 3 for providing a pressure inside the cavity 19 below supercritical level. The sealing ring 18 is mounted on the head 1 and can be located on the inner cylindrical part of the cap 5. The device (Fig.1-4) works as follows. The cap 5 is pressed against the head 1 (Fig. 2), as a result of which an overpressure is created in the cavity 19 under the cap 5, which with further lowering of the cap propagates to the channel 8 of the nozzle 3 and the channel 7 downwards to the seal 6 and removes the latter from the position it is tightly connected to the membrane 20. As a result, air will flow into the lower part 11 of the chamber 10 and then through the tube 17 into the inner part of the vessel 12 (the bottle), where excessive pressure is created. The cap 5 in its upper part has an opening 22 (slit), which when pressed on the cap is closed by the operator’s finger. When the cap 5 reaches the lowermost position, the finger is removed from the orifice, as a result of which the excess pressure is removed from the cavity 19 under the cap, and the existing excess pressure in the internal part of the device presses the seal b to the membrane 20, thus preserving the excess pressure inside the vessel ( FIG. 3). When the vessel is used for spraying the liquid, the cap 5 is removed and removed, while the nozzle 3 opens and the liquid flows upwards through the tube 17, the chamber 10, the channel 7 and is discharged through the nozzle 3 (Fig. 4). When the pressure on the nozzle is released, the membrane 20 moves back, as a result of which the interaction between the seal 6 and the membrane 20 is restored. The described spray device has a number of advantages over the known one. During storage of the vessel, it is not necessary to maintain an overpressure within it. When using a vessel, you should only slightly raise the cap 5 and then lower it again relative to the head 1, then remove the cap 5 from the vessel and remove it from the vessel. In the case of using a liquid spraying device, this is done by simply pressing the nozzle 3. Multiple short movements the swings during spraying are thus not repeated, but instead
    They are sprayed as easily as using aerosol cans.
    The simplicity of the design of the device ensures the preservation of tightness for a long time due to the slight wear of its elements and the elimination of excess pressure leaking from the vessel in the event that the latter is not used for a certain period of time.
    In addition, the volume around the nozzle 3 remains constant after maximum lowering of the cap 5, which provides an exception to the appearance inside the cavity 19 of the pressure of the supercritical level, which occurs under the conditions of lowering the cap 5 completely and contacting it with the upper surface of the head 1.
    In the case of direct contact of air and liquid in a vessel, in particular, a liquid that is exposed to air, the head 1 of the device (FIGS. 5-7) contains two inner and outer sections 23 and 24 concentrically mounted one into the other to form chambers between them . The sections have flow channels 25, 26 and 27 for the passage of air. The inner section 23 has an elastic sheath 29 fixed in its lower part 28 under the channels, the latter entering the inside of the vessel 30 to prevent the fluid 31 inside it with air. The valve 32 and the nozzle 3 are mounted on the outer section 24.
    The membrane 20 is sandwiched between the sections.
    23 and 24 and its end portion 33 tightly adjoins the outer section 24, while the valve also fits tightly against the membrane 20 with an interaction force slightly exceeding the engagement force of the end portion 33.
    During operation of the device, the elastic shell is introduced into the vessel 30 after it is filled with liquid 31. When the outer section
    24 is screwed onto the inner section 23, then its lower part 28 is displaced upward into contact with the neck of the vessel, and the elastic shell is tightly clamped between it and the wall of the vessel.
    When the cap 5 is pressed downwards. Regarding sections 23 and 24 when the opening 22 is closed and the air is compressed in the cavity 19, the valve will not open and the membrane end section 33 will be turned downwards (fig. Dash-dotted line). the channels 25-27 down into the elastic sheath 29, where the air pressure is thus increased.
    As soon as the air pressure in cavity 19 drops below the pressure in
    elastic sheath 29, the end portion 33 of the membrane closes the channel 25-27.
    When the nozzle 3 is lowered, the valve 32 opens and the liquid is expelled from the nozzle as a spray jet (Fig. 5). At the same time, its pressure drops to a level lower than the atmospheric one. As a result, the elastic shell fills the osculate gradually at a rate equal to the flow rate.
    C are liquid 31, the air and the liquid not contacting each other inside the vessel.
    The device (Fig.8) can be equipped concentrically mounted on
    5 of the inner cavity of the column 34 with a tube 35 covering the head 36 to form a channel 37. At the bottom of the tube 34 there is a flange 38 for sealing, while the flange fits tightly to the walls of the column 34. In this case a cavity 19 is formed between the head 36, a tube 35 and cap 39.
    When the opening 22 is blocked, the air pressure inside the cavity 19 is increased so that the membrane 20
    5 opens air communication with the vessel 40 for liquid. In this case, air flows into the vessel and an overpressure is created inside the latter.

    The spraying process is carried out as previously described.
    When using the proposed spraying device, known vessels can be used and there is no need to develop new machines for the manufacture of new ones, which is economically advantageous.
