Definitions

  • the invention relates to a spray can for spraying or foaming liquid products with a product container in a housing jacket with a spray head, which is provided with a product channel and an air supply line, the latter being connected to the pressure port of an air pump, the spray head a closure part, one to this displaceable actuating part and devices for introducing compressed air into the nozzle of the spray head.
  • the invention is therefore based on the object of improving an automatic spray can with the features of the type mentioned in such a way that, particularly when the device is switched off, the compressed air generating the spray jet is abruptly broken down, so that no spraying or dripping takes place.
  • the closure member has a passage provided with line connections, in that a movable with the actuating part, biased by a return spring control slide with passages and sealing beads for air and product liquid, limited by stops to a stroke, is kept movable that in the spray position with the return spring compressed, the line connections in the closure part are connected to the passages of the control slide for air and product liquid and in an adjacent vent position with partial relaxation of the return spring, the line connections in the closure part are partially separated and are partially arranged in connection with vent lines leading to the atmosphere, and that in the closed position with the return spring maximally relaxed, the control slide is in its uppermost, most protruding position from the passage.
  • the spray can according to the invention is therefore provided with a special closure part which seals the opening of the product container, which is preferably arranged at the upper end of the product container.
  • this specially designed closure part is the aforementioned passage, from which line connections start, and is located in the passage the movable control spool.
  • Each spray can has a closure part, although a spray nozzle may also be arranged in this closure part, but according to the invention the movable control slide ensures that the line connections in the closure part, which originate from its passage, and the spray nozzle both with product liquid and with Compressed air on the other hand, partially closed or connected to the corresponding fluid sources.
  • a venting position is arranged next to the spray position on the one hand and next to the closed position on the other hand.
  • the vent position is preferably between the spray and the closed position.
  • the three operating positions mentioned result from the respective position of the control spool. From the spray position, the return spring can therefore only bring the control slide into the closed position after the vent position has been passed over beforehand.
  • the supply lines of air are connected to the outside atmosphere, so that pressure is immediately reduced, and moreover the lines for the supply of product liquid are shut off at the same time.
  • Switching on the new spray can is also much more convenient according to the invention, because when the user presses the spray head, the control slide must first be brought into the vent position and then the spray position is reached so that the spray jet emerges from the nozzle immediately, ie the jet begins suddenly and abruptly breaks off.
  • a spray characteristic is particularly important if spraying is to be carried out at short intervals, such as when styling hair, painting paint, etc.
  • a spray can is thus created which nevertheless has the function of a real "aerosol can character", because the whole spraying process is similar to expires when using propellant gases and in particular post-spraying is switched off.
  • a lower sealing bead is arranged between the air passage of the control slide and its passage for product liquid for closing the line connection for air in the closure part in the closed position of the control slide.
  • the control slide is designed particularly expediently because the individual passages to be separated from one another are separated by bead-like parts which can also be used as sealing devices, e.g. for closing an air supply line.
  • the control slide is actuated or moved by finger pressure with the hand of the end user or user, who places his finger on the top of the finger rest of the actuation part and, against the force of the return spring, moves the actuation part together with the control slide down towards the product container . If the user releases the finger, the return spring pushes both the actuating part and the control slide back into the starting position, the maximum stroke being limited by stops.
  • the return spring can be, for example, a spiral spring, which is still under tension in its maximally relaxed position, so that the actuating part remains held in the initial or closed position against the abovementioned stop. So it goes without saying that in the spraying position the control slide is located furthest in the passage of the closure part and the return spring is maximally compressed, that a further compression of the return spring would still be possible, but is not desirable.
  • line passages are opened or closed, specifically for the compressed air, which is generated in the manner described by the motor-driven air pump, or on the other hand for the product liquid.
  • the compressed air can be connected to the interior of the product container when the control slide is opened, so that the pressure is applied to the liquid level of the product liquid and thus presses this product liquid through a riser connected to the product channel and from there into the spray nozzle.
  • the air passage of the control slide is formed by a recess in the surface of the control slide extending in its longitudinal direction over at least the stroke length.
  • a recess can be provided, for example, by reducing the diameter over a certain height of the cylinder. This ensures that air can flow past ring seals when the ring seal, which generally acts on a sealing bead, reaches the area of such a recess, namely by moving the control slide within the passage of the closure part.
  • the spray can according to the invention is advantageously further designed in that an annular seal is attached to the end of the passage facing the actuating part on the closure part for interaction with the surface of the control slide outside its air supply channel in the closed position.
  • an annular seal is provided on the closure part, which depending on the position of the control slide a sealing bead is engaged so that a line passage is interrupted, or the sealing bead is arranged outside the ring seal, so that the closure is released and the line connection is made instead.
  • an upper sealing bead preferably provided with a ventilation recess, is formed between the air supply duct of the control slide and its air passage for interaction with the ring seal located in the closure part.
  • This upper sealing bead can, only interrupted by individual line exits, extend over the entire upper end of the slide, which is ultimately attached to the actuating part.
  • a preferred embodiment is provided with the characteristic that the elongated passage in the closure part is arranged centrally and parallel to the longitudinal central axis of the closure part, the line connections of the closure part extend perpendicularly radially to the passage, the product channel in the extension of the passage downward to that of the return spring Side of the closure part is provided that further the spool is longer than the passage and at the two ends of the spool in the middle in its longitudinal axis and opening in radially extending channels openings for air and product liquid are arranged and that finally the downstream end of the air supply line over the Control slide is connectable to the interior of the product container.
  • Such an embodiment is technically particularly inexpensive to manufacture and also leads to the best user function because the end user generally presses on the middle of a finger rest and, in the construction described above, the control slide is arranged just below it. So mainly axial forces act, so that wear can be kept low and the structure with the closure part, control slide and actuating part is hardly subject to wear. Furthermore, it is advantageous if, according to the invention, the product container is arranged displaceably in the housing jacket and is held on a switching finger that is resiliently biased against the housing jacket to actuate a motor switch.
  • the housing jacket accommodates the drive units with battery, motor, switch and air pump in its closed lower part, and the product container is pushed onto the energy supply described in the upper part. Due to friction, the product container sits quite firmly in the casing. Nevertheless, the friction between the outer wall of the product container and the inner wall of the housing shell is kept so low that when the finger is pressed on the actuating part, the entire product container moves down, as a result of which the motor switch is switched on.
  • the shift finger is fastened to a displaceable guide pin which is supported by a shift spring against the housing base attached to the housing jacket.
  • the housing base for example, separates the energy part from the receiving space for the product container.
  • the housing base can have an opening, in which the guide pin mentioned is slidably held and biased by the switch spring.
  • a sealing membrane can extend, for example, over the guide pin, the switching finger and the motor switch, so that no liquids, dirt or the like can get into the energy part under the housing base, although the space is accessible from above for the end user so that it can e.g. pushes the product container from above into the housing jacket down to the shift finger.
  • the switching spring is harder than the return spring which prestresses the control slide resiliently against the closure part, then the control slide is moved first, and then the motor for the air pump is switched on or is switched off when If the air pressure is still present, the fluid supply is shut off by the slide, and only then is the air pump switched off.
  • the invention is expediently further embodied in that a line connection in the closure part is connected to the product container via a valve device.
  • This is the line connection that feeds the product liquid to the swirl nozzle.
  • This line connection thus connects the swirl nozzle on the one hand to the interior of the product container on the other.
  • the valve device now ensures that, depending on the position of the spray can, the valve closes or keeps the mentioned line connection open.
  • the valve device mentioned here ensures that the product liquid does not flow into the swirl nozzle without actuating the actuating part.
  • the line connection to be closed is in fact necessary to apply air to the interior of the product container so that this air pressure presses the product liquid through the riser pipe into the nozzle.
  • said valve device has a ball cage, preferably with a steel ball or the like, which is supported on retaining cams and is held within ring-shaped roller webs and can be moved against a sealing seat. In no position of the spray can, i.e. also of the product container, liquid can thus penetrate into the air pump via the mentioned line connection, which is an air supply duct. If the device is held horizontally or upside down, the steel ball rolling in its sealing seat prevents liquid from penetrating into the air supply duct described.
  • Another embodiment of the invention is characterized in that in the product container a film container which can be filled with product liquid is fastened, the outlet opening of which is sealingly connected to the product channel, the upper end part of the control slide connected to the actuating part of the spray head being closed without a passage for air forms, the downstream end of the air supply line opens into the interior of the product container and at least one line connection of the closure part is connected to the interior of the product container.
  • the upper end of the control slide is no longer provided with a central channel, for example for the air supply, but rather is designed to be closed, for example solid. So that the compressed air can no longer be guided from the outside to the spray nozzle via the control slide and the passage in the closure part.
  • the above-mentioned line connection in the closure part ie the air supply channel between the passage and the interior of the product container, is used to convey the compressed air from the product container, which is located outside the film container, into the spray nozzle.
  • the product liquid passes from the film container to the spray nozzle via the product channel.
  • the advantage of this embodiment lies in the avoidance of the valve device mentioned above, in particular that with the ball cage.
  • the product liquid is only in the film container here, so that the interior of the product container outside of it is dry. Even if the spray can according to the invention is arranged upside down, liquid can no longer get into the spray nozzle unintentionally. Nevertheless, the displacement of the control slide can ensure that the spray begins abruptly and also ends suddenly, if this is desired by the user and controlled by finger pressure.
  • Another embodiment is characterized in that the film container which can be filled with liquid product is fastened in the product container again, the outlet opening of which is sealingly connected to the product channel, but the film container is now provided with a check valve connected to the downstream end of the air supply line and with a riser , Furthermore, the product container can only be opened via the product channel by means of the control slide.
  • the check valve ensures that the air pump has a compressed air cushion inside the film container can build, which presses on the liquid product or its liquid level and thus conveys the liquid through the riser in the desired manner into the spray nozzle if the control slide allows this.
  • the interior of the product container is dry again with the resulting advantages, as mentioned before.
  • a further alternative embodiment of the spray can according to the invention is characterized in that, as above, a film container which can be filled with product liquid is fastened in the product container, the outlet opening of which is sealingly connected to the product channel, but here the downstream end of the air supply line via the control slide to the interior of the Product container is connectable and the product container can only be opened via the product channel by means of the control slide.
  • the compressed air acts on the film container from the outside and thus presses the product liquid into the spray nozzle when the control slide is in the appropriate position.
  • this air located in the interior of the product container cannot be led directly from the product container into the spray nozzle, but instead the passage arranged in the center at the upper end of the control slide is used, which leads the air via a radially extending channel into the spray nozzle.
  • the housing jacket is provided with an orientation screen that reduces its cross-section, according to which the product container has a recess on the outside, then the insertion of a new product container after an exchange is made easier for the end user, because then the rotational position is always exactly correct, so that one at a corresponding one Embodiment provided below air inlet opening in the product container then always fits exactly on an air nozzle on the air supply line.
  • the mentioned riser is known per se from other spray cans and can also be used in most of the above-mentioned embodiments of the invention. It can partially be designed as a riser pipe and, in the case of the embodiment with the check valve in the film container, is designed as a hose, to the outlet opening of which a weight is preferably still attached, so that the outlet opening of the riser hose is always in the volume of the film container in which it is located the product liquid stops, so that regardless of the position of the entire spray can, the desired function is always guaranteed, ie abrupt insertion of the spray jet when actuating and breaking off the spray jet when relieving the actuating part.
  • a first embodiment of the first embodiment of a spray can which is best seen overall from FIG. 5, is described with reference to FIGS. 1 to 6.
  • the energy part with batteries 39, a motor switch 34, direct current motor 36 and air pump 37 with pressure connection 60 is located in a housing shell 42 of cylindrical shell shape between an underbody with suction filter 38 and a housing bottom 35.
  • the energy part takes up well the lower third of the cylindrical housing shell 42.
  • the upper two thirds are filled by a product container 26, which can also be cylindrical, but is preferably flattened on one side, so that there is a flat container surface 76 in the illustration in FIG. 6. In conjunction with an orientation panel 44 attached to the housing jacket 42 at the top (FIG. 8), this serves to correctly insert the product container 26.
  • the product container 26 is provided at the top with a spray head, generally designated 1a.

It consists of a sealing part which surrounds the product container 26 at its upper outlet and which is provided at the top with an actuating part 1 and a nozzle receptacle 3 in which a spray nozzle 4 is seated. If one looks in FIGS. 1 to 5 from top to bottom, as can be seen for example in FIG. 6, then one sees the finger rest 5 of the actuating part 1, which opposes the force of a return spring 15 in the direction of the dash-dotted longitudinal central axis 67 (FIG. 3) the ver closing part 2 is movable.
  • a stop ring 16 which can cooperate with a stop ring 17 on the actuating part 1 such that the return spring 15 sets the maximum distance of the actuating part 1 from the closure part when the actuating part 1 is released.
  • This distance is also found on the underside of the actuating part 1, which is maximum in the closed position according to the illustration in FIG. 1 and represents the stroke H, while in the spray position according to FIG. 2 it has become zero.
  • the stop rings 16 and 17 are at a distance of the stroke H from one another.
  • the spray head 1a also has devices for introducing compressed air into the spray nozzle 4, of which there is a control slide 13 (and the motor switch 34 already mentioned). As will be explained with reference to FIG. 2 and the spray position, it depends on the position of the control slide 13 whether a connection is created between the spray nozzle 4 and the air supply line 14 or this connection is interrupted.
  • the closure part 2 has a longitudinal central axis 67, which is also the longitudinal direction of the control slide 13.
  • the elongated passage 61 in the closure part 2 is arranged centrally and parallel to the longitudinal central axis 67.
  • line connections 20, 21, 27 extend from the passage 61, 20 being the air supply channel for the spray nozzle, which is shown as a two-fluid swirl system 24 (FIG. 3) with a swirl nozzle opening 25, 21 the air supply channel to the product container 26 and 27 represent the inlet opening to the spray nozzle 4.
  • control slide 13 is longer than the passage 61 itself, so that the passage 61 in all positions tion of the spool is essentially occupied by this.
  • the passage for air is with the radially extending air supply duct 19 and the passage 71 for product liquid is connected to the slide channel 22 of the control slide 13.
  • FIGS. 1 to 3 also show an annular groove 18 next to the downstream end of the air supply line 14, this annular groove extending next to the upper distribution space in the control slide in connection with it.
  • This upper end of the control slide 13 is connected to the actuating part 1, so that the control slide 13 can slide against the force of the return spring 15 in the direction of the axis 67 together with the actuating part down and up.
  • the end of the air supply line 14 moves together with the control slide 13.

  • This last embodiment, not shown, is an alternative to that of FIG. 11 in that the Product liquid 52 in the film container 47 is pressed into the spray head 1 a by air pressure in the interior 74 of the product container 26.
  • the spray can works as follows.
  • the actuating part 1 is normally in the closed position in FIG. 1.
  • the finger rest 5 of the actuating part 1 By finger pressure on the finger rest 5 of the actuating part 1, the latter is brought into the spraying position in FIG. 2, and it is delivered by the air supply line 14
  • Compressed air is conveyed into the control slide 13 via an annular groove 18. It flows through the air supply channels 19 into the air supply channel 20 of the two-fluid vortex system 24 and at the same time into the air supply channel 21 of the product container 26. Due to this pressurization on the surface 32 of the product liquid 52, liquid product is passed via the riser 7 into the slide channels 22 and from there promoted in the product channel 23 of the vortex system 24. This is where the swirling of product takes place with the air flowing in at the same time, so that a fine spray mist leaves the spray nozzle 4 through the swirl nozzle opening 25.
  • the ball cage 8 with the steel ball 9 also serves this purpose and prevents the penetration of product liquid into the air supply system when the spray can is held horizontally or upside down.
  • the steel ball 9 rolls over the webs 10 into the sealing seat 11 and thus closes the air supply channel 21 for the product container 26.
  • the inflowing air prevents liquid from entering the product container 26 into the air supply channel 21. If you interrupt in this Position the spraying process, then it can happen that due to the internal pressure in the product container 26 a small amount of product liquid gets into the air supply channel 21 before the sealing bead 29 can effectively close this channel. This phenomenon is prevented with the help of the ball cage in the manner described.
  • the steel ball 9 falls back into its starting position, where it finds its hold on the holding cams 12.
  • the film container 47 can practically perform the riser function, but with the following serious advantages: the sprayer can spray the contents perfectly in all positions, including overhead. The possibility that product liquid gets into the air-carrying channels is excluded.
  • product liquid 52 is always present in the product channel 51, so that there is no delay in the spray effect after actuation by pressure on the finger rest 5.
  • the embodiment according to FIG. 11 works in such a way that when the finger is pressed on the actuating part 1, the motor switch 34 sets the air pump 37 in operation and compressed air is conducted in two parts. Firstly, it reaches the interior of the film container 47 via the air end connector 48 and the check valve 75, as a result of which the pressure exerted therein pushes the product liquid 52 upward into the spray head 1a. Second, compressed air reaches the air distribution space 33 in the control slide 13 via the air supply line 14, as in FIG 4 funded.
  • a check valve in the product channel of the closure part is at a distance from the spray nozzle directed entrance opening is arranged.
  • This check valve can consist, for example, of a sealing seat for a steel ball (when the spray can is upright in the vertical direction) the upper end of the riser pipe.
  • This check valve thus ensures when spraying is switched off, i.e. Removal of finger pressure from the actuating part for a closure so that the liquid column of the product in the riser is prevented from falling down.
  • the liquid column is kept within the riser for days. Such a tightness is sufficient, however, if the liquid column is held for a few seconds because the intervals in critical applications are shorter than this time.
  • the liquid application of the product can thus be used even more quickly and the entire spray can is more convenient.
  • FIGS. 12 and 13 This new embodiment of the spray can is shown in FIGS. 12 and 13, specifically in FIG. 12 in a broken-away vertical sectional view of the upper part of the product container and without an actuating part, and in FIG. 13 as view A on FIG. 12 from below, although the product container 26 has been omitted here is.
  • the closure part 2 is pressed onto the product container 26 over the clamping bead 57 and is snapped captively underneath.
  • the clamping bead 57 is annular and hollow in the middle, so that a riser 7 can protrude freely.
  • a hollow cylinder protrudes approximately in the area of the inner circumference of the clamping bead 57, into which an annular sealing lip 58 is clamped when the closure part 2 is placed on the product container 26. This serves to hold the closure part 2 upright after clamping by means of a clamping bead 57. Coaxially in the closure part 2 one can see a hollow cylinder-shaped part within the sealing lip 58, which forms the product channel 51.
  • the steel ball 53 shown in broken lines lies in the closed state and is lifted into the position 55 shown in solid lines during the spraying process.
  • the check valve is therefore closed when the steel ball 53 is in the sealing seat 54.
