Definitions
- Spray bottles used for a wide variety of purposes in everyday life are mostly disposable containers which, after they have either been completely emptied or at least depressurized, must be disposed of separately.
- spray bottles used for a wide variety of purposes in everyday life are mostly disposable containers which, after they have either been completely emptied or at least depressurized, must be disposed of separately.
- several proposals have already been made, in particular for refilling spray bottles.
- a device for refilling spray bottles which has a pressure container screwed to a spray head or otherwise connected manually or mechanically detachably.
- the spray head is removed from the completely empty pressure container, after which the pressure container can be filled again with spray material. Filling up propellants
- Spare sheet middle takes place after the spray head has been screwed back onto the container via the spray valve.
- a device and a method for refilling spray bottles via their filling valve are also specified in the above-mentioned DE-OS. It is assumed that the spray bottle is completely empty, which is filled with the intended contents, known as flowing material, via a filler neck and then also with compressed air via the fill valve.
- Any residues not fully expelled in the spray can therefore contaminate the refilled filler.
- a blowing device provided for blowing away dust which has an essentially cylindrical pressure vessel with an inwardly curved bottom and with a neck-like narrowing upper part, on which a blowing valve is provided.
- a non-return valve via which by means of an air pump
- REPLACEMENT LEAF can be pumped into the pressure vessel. This can be released in a metered manner via the blow valve, so that the blow device is suitable for blowing away dust or other dirt on a smaller scale.
- a device for refilling propellants in spray bottles which is provided with a filling valve at the bottom of the corresponding pressure container.
- the filling device has a pressure container which is brought to the required filling pressure by means of an electric pressure pump.
- the pressure container is connected to an outlet valve which can interact with the filling valve provided on the bottom of the spray bottle and which is opened when the spray bottle is placed on the outlet valve. If the pressure inside the partially empty spray bottle has dropped below the filling pressure in the pressure container, propellant is refilled from the pressure container into the spray bottle.
- this device can maintain a substantially constant spray pressure until the spray bottle is completely emptied by repeatedly refilling propellant into the corresponding spray bottle, there is no refilling of spray material and therefore no real repeated use of the spray bottle.
- DE-GM 90 13 487 describes a spray bottle which has an essentially cylindrical pressure vessel with a curved bottom and an internally threaded, bottle-like tapering neck.
- the neck encloses a relatively wide filling opening, into which a larger screw cap provided with internal threads is screwed.
- the screw cap carries a spray valve, by means of which the spray bottle is actuated in the
- a filling valve designed as a check valve, via which a suitable propellant can be filled.
- the spray bottle is filled by unscrewing the screw cap and the filling opening with the appropriate amount of the spray material. After the screw cap has been screwed on tightly, the appropriate amount of propellant is added via the filling valve arranged on the bottom.
- This refillable spray bottle is provided with a screw cap which, even after being opened and closed several times, must be reliably leakproof, which increases the effort involved in producing this spray bottle.
- the first process step in which the spray bottle is filled with a pressurized fluid, initiates a cleaning phase. Regardless of whether the spray ⁇ bottle is already empty or whether residual amounts of spray material and possibly a residual charge of ad may not blowing agents are present in the spray bottle, this maintaining a defined pressure pad.
- the pressurized fluid in the spray bottle expels any spray material residues and then flows mi * . ; o flow rate, whereby it can whirl up spray material residues hanging on the inside wall of the spray bottle or lying on the bottom thereof and discharge it to the outside.
- the spray bottle is empty following this emptying process. It contains neither fluid under pressure nor spray residue.
- the first and the second method step thus form a cleaning process, the defir.
- the filling process is initiated by the third process step in which new spray material is poured into the spray bottle.
- the spray material can be identical to the spray material previously contained in the spray bottle. If necessary, and if necessary, another spray material can be filled in, in which case the requirements for the cleanliness of the spray bottle are increased. To ensure this, the first and second process steps can be repeated one after the other, if necessary several times.
- the filled spray bottle is now ready for operation be ⁇ . With the specified process steps multiple filling and refilling of spray bottles possible.
- the spray bottles can be reused many times, so that empty spray bottles no longer have to be thrown away. That reduces the amount of gauze.
- both the full steps of the first, third and fourth process steps as well as the emptying process are carried out via one and the same additional valve attached to the spray bottle, Gas Fuilventii through the last process step, nairuicn aas ⁇ in filling of pressure medium in the spray bottle, of possibly
- the separate full valve can be equipped with a cross-section such that both the felling and the emptying take place in a very short time.
- a drastic emptying process ensures a good cleaning effect of the spray bottle , because the fluid then flowing out at high speed can discharge spray residue.
- a gas is used as the fluid that does not condense even under pressure, a pressure cushion is formed that can expand very quickly. In particular, there is no delay, such as when expanding liquefied gases which first have to absorb ambient heat in order to be able to evaporate.
- a gas mixture whereby compressed air can be used, especially if the spray material to be used is insensitive to atmospheric oxygen.
- a sufficient spray effect and also a sufficient cleaning effect are achieved if the predetermined pressure at which the fluid is located is dimensioned such that the amount of fluid to be filled into the spray bottle is sufficient to expel it, depending on the volume of the spray bottle and the amount of the spray material is.
- a good reproducibility of an intended Sprühgut ⁇ filling in the prayflasche is achieved if the to be filled in the third process step amount of new spray good is metered by an automatically operating dosing and filled '.
- the free space remaining in the spray bottle is determined at the same time ier take the pressurized fluid to be filled in afterwards. This ensures that there is sufficient fluid in each spray bottle to be filled in order to be able to drive out the entire spray material in later use.
- An overfilling with spray material, which would result in a lack of fluid serving as a propellant, is therefore excluded.
- the fluid to be filled in in the fourth process step is a gas.
- a gas mixture and in particular compressed air can be used.
- the process is simplified if the fluid used for the flushing process and the fluid used in the fourth process step to fill the spray bottle with pressure medium originates from the same fluid source in all of the process steps mentioned. If compressed air is used in the example, a common compressed air connection is sufficient. - S -
- the part of the task aimed at creating a refillable spray bottle is solved by a spray bottle with the features of claim 16.
- the spray bottle has, in addition to the already existing Sprühven ⁇ til an additional filling valve, whereby the switching valve Full arbitrarily passage in both flow directions is ⁇ bar. This means that it can be used to fill and empty the spray bottle.
- the separate installation of the filling valve allows it to be designed according to the specific needs when filling and emptying. In particular, it can be provided with an effective cross section which is markedly larger than that of the spray valve. This allows effective cleaning and fast filling processes.
- the spray bottle has a substantially cylindrical pressure vessel with an inwardly curved bottom, in the recess of which the full valve is arranged, the full valve is completely absorbed by the bottom curvature of the spray bottle, so that it remains on a flat surface
- the surface can be set up without falling over.
- the separate filling valve arranged on the bottom shifts the center of gravity of the spray bottle downward, so that even spray bottles that are almost completely empty have improved stability.
- the spray bottle can be filled with a filling device without having to be held separately.
- the holding of the spray bottle which is necessary when filling the spray bottle, takes place on the flange itself.
- the pressure container can have a bottle-like neck on its upper side, which is firmly closed with a cover part carrying a spray valve. Any thread it is not necessary to releasably connect the lid oil to the rest of the pressure bottle in the spray bottle.
- a fixed connection can be produced inexpensively and permanently, for example as a flanged connection.
- the part of the task aimed at creating a device for filling spray bottles is achieved by a device having the features of claim 20.
- the device has a fluid coupling which can be brought into a low-leak connection with the filling valve, which ensures that when the spray bottle in question is filled or emptied, neither spray material nor fluid escapes and is lost or the device is contaminated.
- the control unit controlling the fluid supply and discharge through the fluid coupling and the transfer of predetermined quantities of spray material from the spray material supply into the spray bottle enables both one or more cleaning processes to be carried out and the spray bottle to be reproducibly filled with the Spray material and with pressurized fluid.
- the fluid source is a compressed air source in a simple manner.
- the fluid coupling can be designed as a locking coupling. This ensures that the fluid supply to the spray bottle is automatically interrupted when the spray bottle with its filling valve is released from the closure coupling. A backflow of fluid or sprayed material from the spray bottle into the closure coupling is reliably avoided because of the fluid pressure present until the closure coupling is closed. The connection is therefore low-leak.
- control unit has an arbitrarily controllable channel for pressurizing the fluid coupling with pressure - Lo ⁇ henden fluid, the fluid can be added to the spray bottle arbitrarily regardless of the filling of the spray bottle with spray material.
- control unit has an arbitrarily controllable channel for blowing off fluid stored in the spray bottle.
- a fluid supply located in the spray bottle can be let out in a simple manner, as a result of which residues of spray material located in the spray bottle are printed out and also carried away.
- the spray bottle is then empty and depressurized, thus creating a defined starting basis.
- the spray bottle is advantageously filled with spray material via an arbitrarily controllable channel provided in the control unit, in which a metering unit and a pump unit for metering and pumping spray material are arranged.
- the dosing unit and the pump unit can be formed by a single dosing pump, which combines both units. A simple and reliable structure is thus achieved.
- a particularly simple and reliable solution is obtained when the metering pump is actuated by the pressurized fluid.
- the device then manages without additional auxiliary energy, such as, for example, electrical energy.

- the filling valve 8 has a concentric through-hole 83 which tapers in several stages towards its mouth 84, which lies away from the base 5.
- the through bore 83 initially runs in a cylindrical shape, whereupon it widens with a sealing surface 85 lying on a conical surface and merges into a further essentially cylindrical part.
- an O-ring 87 belonging to a valve body 86 is supported, which sits tightly in an annular groove 88 of the valve body 86.
- An annular shoulder 89 is provided on a side of the valve body 86 opposite the O-ring 87, on which a helical spring 92 supported at the other end by a snap ring 91 is supported.
- the closure coupling 14 is provided, which is shown in FIG. 3 in the axial extension of the filling valve 8.
- the locking coupling 14 has a base body 98 consisting of two tube-shaped Tilgen parts 96, 97 screwed together, which limits an approximately cylindrical passage 99 connected to the pressure channel 12 shown in FIGS. 1 and 2.
- a stationary valve mandrel 101 is provided within the passage 99 coaxially with the otherwise rotationally symmetrical base body 98, which is screwed to the base body 98 via a truncated cone-shaped, multi-perforated holder 102.
- the valve mandrel 101 has a diameter that is smaller than the diameter of the mouth 84 of the through bore 83 At its mouth end, the valve mandrel 101 carries an O-Rmg 103 in an annular groove, which seals in the rest position with an annular valve member 104.
- the valve member 104 in turn has an O-ring 106 inserted in an annular groove open on both sides, which seals it against the part 96.
- the O-Rmg 106 lies both on the inner wall of the part 96 and on a rear flank 107 of an axially displaceable, coaxially arranged locking ring 108.
- the locking ring 108 radially covers the bore 96 arranged in the part 96, in which locking balls 110 of the same diameter are seated.
- the locking balls 110 protrude outward beyond the outer lateral surface of the part 96 and protrude into an inwardly open annular groove 112 of the loose sleeve 15, which is mounted coaxially and displaceably on the part 96.
- the loose sleeve 15 is tensioned by a helical spring 114 supported on an annular shoulder provided on it and at the other end on the part 97 on the locking balls 110 and thus on the bottom 5 of the spray bottle 2.
- the valve member 104 is tensioned by a coil spring 115, which is supported at the end of the valve member 104 itself and at the other end of the holder 102.
- the bias of the coil springs 114, 115 biases the valve member 104 to its closed position with its O-Rmg 106, and the annular groove 112 of the loose sleeve 15 is printed against the locking balls 110 with an inclined surface 116.
- the loose sleeve 15 merges into a plate 121 provided with an edge 120, which forms the spray bottle holder 16 shown in FIG. 1.
- the device 1 for filling spray bottles 2 described so far operates according to the method according to the invention as follows: With reference to FIGS. 1 to 3, it is assumed that the spray bottle 2 is inserted with its filling valve 8 into the closure coupling 14 at the beginning of the filling process.
- the flange of the filling valve 8 formed by the sections 79 and 81 enters the opening formed by the passage 99 in the part 96 of the lock coupling 14.
- the filling valve 8 with its end face surrounding the mouth 84, pushes the valve member 104 against the action of the pretensioning of the screwdriver eder 115 into the locking coupling 14, the O-ring 106 sealing with the flat surface adjoining the mouth 84.
- the valve member 104 slides off the O-ring 103 which is mounted on the valve mandrel 101 in a stationary manner, as a result of which the locking coupling 14 opens.
- valve mandrel 101 rests with its face-side flat surface on the outward-facing flat surface of the valve body 86 and moves it against the action of the prestress of the coil spring 92 into the through bore 83, whereby the O-ring 87 lifts off from the sealing surface 85 .
- the full valve 8 is thus also open.
- the control circuit has the state shown in FIG. Compressed air from the compressed air source 45 then penetrates via the compressed air channel 47 into the pressure container 3 of the spray bottle 2 via the compressed air channel 47 and the check valve 48. This happens regardless of whether there is a residual filling of spray material and / or any propellant still present, that is to say compressed air, for example, in the pressure container 3.
- the pressure container 3 of the spray bottle 2 is thereby filled with compressed air up to the operating pressure of the compressed air source 45 of, for example, 8 bar. This process takes place very quickly immediately after inserting the spray bottle 2 with the filling valve 8 into the closure coupling 14.
- the control line 59 receives compressed air.
- the control line 51 is depressurized.
- the 3/2-way valve 49 accordingly switches over, as a result of which the compressed air channel 47 is shut off and no further compressed air is supplied from the compressed air source 45 into the compressed air channel 47.
- the blow-off valve 57 located in the second controllable compressed-air channel 55 switches over, thereby clearing the way from the spray bottle 2 and the pressure channel 12 via the compressed-air channel 55 and the blow-off valve 57 to the outlet 58.
- This path has a relatively low flow resistance, so that the compressed air stored in the pressure container 3 of the spray bottle 2 first expels any spray material residues which may be in the pressure container 3 and then flows out even at a relatively high flow speed.
- the pressure vessel 3 is depressurized and empty.
- the control line 69 is now pressurized, as a result of which the 5/2-way valve switches and thus connects the partial space delimited by the pneumatic piston 42 and the sealing plate 34 to the compressed air source 45 and thus to compressed air acted upon.
- the pneumatic piston 42 therefore moves to its left position in FIGS. 1 and 2, taking the piston 37 with it via the piston rod 36.
- the metering cylinder formed by the piston 37 and the cylinder 28 thereby draws spray material out of the spray material supply 46 via the ratchet valve 33.
- the pneumatic piston 42 As soon as the pneumatic piston 42 reaches its m FIG. 2 position, it switches over the 3/2-way control valve 72 via a symbolically indicated plunger, thereby connecting the control line 61 to the compressed air source 45. As a result of the pressure now present on the control line 61, the blow-off valve 57 switches over, so that the second controllable compressed air channel 55 serving for blowing off is closed. In addition, the 5/2-way valve 68 is switched back via the pressurized control line 61, so that the compressed air arriving from the compressed air source 45 now flows via the line 66 into the other partial volume delimited by the pneumatic piston 42 and the head plate 41 is directed. The pneumatic piston 42 now pushes the piston 37 into its rightmost position in FIG.
- the 3/2-way valve 49 is switched back to its position shown in FIG. 2, whereby the channel 47 is again connected to the compressed air source 45 and the pressure container 3 of the spray bottle 2 Via the 3/2-way valve 49, the compressed air channel 47, the check valve 48, de Closure coupling 14 and the full valve 8 are charged with compressed air up to the operating pressure of.
- the spray bottle holder 16 connected to the Losehulse 15 is moved downwards, ie from the bottom 5 of the spray bottle 2 moved away until the annular groove 112 comes back into the area of the bores 109.
- the valve member 104 is now displaced, the lock 108, the locking balls 110 driving radially outward.
- the locking balls 110 lock the loose sleeve 15 m in this position.
- the pressure channel 12 is under pressure, so that in the unlocking process just described, a small amount of compressed air may possibly escape to the outside, but in no case can spray material 2 filled in the spray bottle 2 escape.
- the filling process is ended when the spray bottle 2 is removed from the device 1.
- the operation of the device is very simple. After inserting the spray bottle 2 m into the device 1, only the keys 21, 22, 23 are actuated one after the other and the filled spray bottle 1 can be removed.
- the filling quantities and full prints introduced into the spray bottle 2 are not dependent on the duration with which the buttons 21, 22, 23 are printed.
- This filling process is suitable both for filling empty and for refilling partially or completely emptied, already used spray bottles. If a spray bottle to be filled is to be cleaned particularly thoroughly of any spray material residues present in the pressure container 3, the flushing process can be repeated several times by actuating the buttons 21, 23 several times.
- the process can be used to fill the spray bottle 2 briefly through the steps beschrei ⁇ ben:
- a separate full valve 8 can be used as the valve for filling and emptying.
- a gas can be used as the fluid, for example compressed air is suitable.
- the predetermined pressure should be such that the amount of fluid to be filled in the spray bottle is sufficient, depending on the volume of the spray bottle and the amount of spray material, to expel the entire amount of spray material filled.
- the outlet process taking place in the second method step should preferably take place over a period of time which is at most a few seconds.
- the maximum flow rate of the fluid flowing out in the second process step is thus chosen to be so high that spray material residues standing in the spray bottle are whirled up and blown out.
