Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid dispensing and atomizing device, and is particularly applicable to devices used as marking or coloring instruments in the graphic arts and fine art fields. However, the application of the present invention is not limited to such fields, but can also be applied to fields such as the pharmaceutical field where liquids are required to be used in a finely atomized form, and various types of liquids are used in atomized form. It is also useful for applications where distribution is required. However, for the sake of clarity, the invention will be described with reference to applications in the field of graphic and fine arts.

In the field of graphic and fine arts, pens have long been used as marking instruments, especially for professional use.

In this case, it is known to provide a set of felt-tip pens, each of which produces a specific shade of a specific color.

Since a large number of shades are required for each color, the total number of felt-tip pens in a set is also large, for example, 150 felt-tip pens.

Although such felt-tip pens have a number of advantages,
It is not possible to make all the markings and colors required. In particular, markings formed using felt-tip pens have sharp outlines, and may form colored markings whose brightness gradually decreases uniformly, or may form markings where two different shades gradually merge with each other. It is virtually impossible to do so. Such a marking effect cannot be easily achieved using a brush or gouache color, but a stream of compressed air is carried by the brush to entrain the colored liquid from the container and transfer it to the spray nozzle. Spray onto the paper or surface to be colored.
This is usually achieved by means of so-called "airbrushes." Although these airbrushes achieve the desired effect very efficiently when used properly, they also have drawbacks.
Second, the density of the sprayed color is adjusted by controlling the air supply, but it is not easy and requires skill to adjust the density while moving the nozzle to mark a desired pattern. Second, the airbrush must be carefully cleaned after completing one spray before spraying the next shade. Furthermore, vessels using air brushes require a separate mooring system for compressed air or other compressed gas.

It is an object of the present invention to be useful as a marking instrument that can achieve effects similar to those achieved using conventional airbrushes, while still meeting the latest requirements in a variety of fields. The object of the present invention is to provide a liquid dispensing and atomizing device that is possible.

According to one aspect of the invention, there is provided a liquid dispensing and atomizing device for distributing a liquid as an atomized spray, the device comprising: a container for containing the liquid to be dispensed; and a container for distributing the liquid from the container to one end of the device. a capillary transfer device for transferring to the tip, and nozzle means for directing a jet of pressurized air or other gas onto the tip so that the liquid is atomized from the tip into the gas jet passing through the tip. The liquid dispensing and atomizing device is provided, which dispenses in an atomized state.

A capillary transfer device, for example, like the nib unit of a conventional drafting pen, is made of an elongated thin metal cylinder and has a filament running in the axial direction, and an annular space between the inner wall of the cylinder and the filament. It may be of the type having one or at most two or three capillaries forming a space through which liquid is sucked by capillary action to the nib. Also,
The capillary transfer device may be of the multi-capillary type, such as conventional felt-tip pens and felt-tip markers, or cores of absorbent material used in fiber-tip pens and markers.

When using such a wick, the tip is preferably pointed or wedge-shaped, and the jet of air or other gas impinges on the sides of the tip at an acute angle to the axis of the tip. It is preferable to arrange it as follows.

A jet of air or other gas impinging on the tip of a wick or other capillary transfer device atomizes the liquid contained in the tip, but also because the liquid is drawn into the tip at least primarily by capillary action. A continuous stream of atomized liquid is produced while the supply of air or gas is maintained.

Preferably, the nozzle means comprises a nozzle connected to a source of pressurized air or other pressurized gas through a manually operated valve. The source of compressed air may be a near compressor or a manually operated air pump, but is conveniently formed as a pressurized air or other pressurized air container connected directly to the nozzle head containing the nozzle. The nozzle head can also be connected by a hose to a remote source of pressurized air or other pressurized gas, with a manually operated valve regulating the flow of gas or air to the nozzle. It is common to operate the valve by manual operation of a lid button or similar means mounted on the outside of the nozzle head, located in the nozzle bed.

In its simplest form, the wick may be held in the path of the air or gas jet by hand; however, if manual or reproducible results are not obtained, the wick may be held by an attachment device. It is preferable. As the container for the liquid to be dispensed, for example a conventional felt-tip pen or marker, or a fiber-tip pen or marker, removably attached to the nozzle head by elastic gripping means is used, and the jet of air or gas is inserted into the felt-tip or fiber-tip. It is convenient to configure it so that it collides with

Although the liquid dispensing and atomizing device of the present invention can take a variety of forms, in advantageous embodiments it is possible to use compressed air or atomizing devices sold under the trade name “FREON”. a self-contained type comprising an elongated container containing another compressed gas (which can also be provided by atomizing a liquid propellant with ease) and a nozzle head attached to one end of the container by a suitable manually operated valve. year,
Compressed air or other propellant gas is configured to flow from the container to one nozzle in the nozzle head by manipulating the valve. The valve can be of any suitable shape, but
Conventional tilt-actuated valves in which the nozzle head is fixed and a valve stem movable within the top of the container is tilted to release pressurized gas from the container have been found to be most preferred. However, as mentioned above, complete separation occurred. It is also possible to connect a source of compressed air or propellant gas to the nozzle head by suitable piping, in which case the nozzle head is conveniently connected to the body of a manually operated valve that controls the flow of propellant gas to the nozzle head. .

Preferably, the nozzle head is configured such that the cross-sectional area of the nozzle through which the flow of gaseous propellant exits the nozzle head is variable. The nozzle cross-sectional area can be changed by forming an annular nozzle with a different area by rotating the outer head member around the inner needle-shaped member through which the propellant passes;
Alternatively, this may be accomplished by varying the width of the annular space formed by axially moving a conical valve member within an opening in a wall extending across a passage through which air or gas is directed toward the nozzle. In this way, it is possible to finely adjust the flow rate of gas passing through the nozzle, and by further rotating the head member about the sword member or by housing the valve member within the l1il II. , the nozzle can be completely closed when the dispensing device is not in use. However, means for varying the cross-sectional area of the nozzle may not be necessary in some cases and the flow rate of propellant passing through the nozzle can be preset to a specific value. In this case, it is possible to use a fixed, non-rotatable nozzle or to omit valve means for changing the flow of air or gas passing through the opening.

A container storing the liquid to be atomized is such that a wick tip extending from the container is located in the path of the air or gas flow passing through the nozzle, and the axis of the wick tip is in the path of the air or gas flow passing through the nozzle. It may be formed as a capsule mounted on the nozzle head so as to form an angle (preferably A being an acute angle) with respect to the direction of . If the wick has a tapered tip, it is useful to attach the capsule to the nozzle head so that the wick can be moved back and forth relative to the air or gas flow, for example by rotating the capsule in the nozzle head. This allows the amount of atomized liquid drawn into the air or gas stream to be adjusted. However, such a configuration may be installed as needed at any time. However, the capsule can be removably attached to the helad member so that after spraying one color, the capsule storing liquid of this color can be removed and replaced with another capsule storing liquid of a different color. is preferred. The container, such as a capsule, contains the liquid to be sprayed in uncombined liquid form, and the end of the wick is immersed in the liquid, or alternatively,
The container forms part of the core absorption t! The absorbent material may be filled with an absorbent material that is in contact with the core so that the absorbent material completely absorbs the liquid. Alternatively, a fixed, non-replaceable, non-refillable container may be used, and the device may be discarded when the liquid in the container is emptied, or a refillable, non-replaceable container may be used.

Alternatively, the container may be constituted by a compartment formed in the nozzle head, the compartment filled with an absorbent material (such as a felt roll) containing a liquid, and the inner end of the wick placed in the compartment. It is also possible to make it rush in. Finally, as mentioned above, the liquid container and the wick may be constructed from a conventional fiber tip pen or marker or a felt tip pen or felt tip marker.

A stand-alone liquid dispensing and atomizing device according to the invention includes an elongated cylinder containing a propellant and having a nozzle head at one end of the cylinder to be similar in size and shape to a pen suitable for manual operation. You can also change the composition. Although this cylinder can be configured to be replaceable and refillable if desired, the atomization device of the present invention can be used after the propellant container is emptied (or, as described above, by a fixed refill). If a non-permanent container is used, it is preferably a "disposable" type that is discarded when the container is emptied. If such a disposable device is used, a set of devices is provided, each with a container containing a liquid to produce the desired shade, similar to the known felt tip or fiber tip pen sets. I understand that. Also,
If replaceable containers are used, it is only necessary to assemble at least one device with a full propellant container and a nozzle head, and a set of containers, each containing a different colored liquid. In this case, for example, three felt tips having large, medium, and small felt tips of different widths for each shade may be used.
It is beneficial to prepare one container. This magnifies the effects achieved by using the device of the invention.

Of course, it is also possible to use non-disposable nozzle heads with disposable propellant and liquid containers. In this case, it may be convenient to provide a valve to control the flow of air or other gas from the container to the nozzle of the nozzle head.

It is necessary that the liquid being sprayed be relatively fluid. That is, such liquid must be absorbed and transported by the wick. For coloring, inks or dyes based on water or alcohol can be used. However, it is also possible to use a 1-nonvarnish, provided that the varnish has a sufficiently low mi or consists of a paint diluted with turpentine oil. Other liquids that need to be sprayed in a controlled manner, such as local anesthetics or drugs used in medical or internal medicine, or perfumes, are also available.

As is clear from the above description, the dispensing and atomizing device of the present invention has a wide range of applications, is simple to use, and is inexpensive to manufacture using relatively inexpensive plastic materials for most of the parts. be able to. The device is useful for creating coloring kits of ``C ink or other coloring media using compatible containers, allowing graphic artists to quickly change colors.The control of the device is simple. This makes it easy to use even for beginners, and it is also suitable for professionals as it can form various forms of atomized liquid.

Embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The dispensing device N (dispensing device 1) shown in FIG.
has. The container (1) contains a pressurized propellant. The propellant may be compressed air, but ``FREON'' (
Easily atomizable propellants (3) are preferred, such as one of the organofluorine compounds sold under the trademark Freon.

The open end of the container (1>) is closed by a valve body (4), which is hermetically fixed to the container, for example by caulking, and a tilt-operated valve (15) of known construction. The details of the tilt-operated valve (15) are not shown, but as will be described later, it is operated by tilting the valve shaft (6).

The dispensing device is usually installed with the nozzle head pointing downwards as shown.
When using a liquid propellant (3), a pumping pipe (7) is installed at the inlet of the valve (5) that extends from the closed end of the container (1) to the gas layer. There is. This allows gaseous rather than liquid propellant to flow into the valve (5) when the container (1) is inverted. When not in use, the dispensing device is stored with the nozzle head facing -, so a valve means (8) such as a ball valve is provided at the open end of the pumping pipe (7) to ensure that the container (1) stands upright. With the valve means (
8) When the dispensing device is closed and the liquid propellant is stored in the tube (7)
Preferably, the valve means (8) is constructed such that when the container is inverted, the valve means (8) is opened. If compressed gas is used as the propellant, no pumping tube is required.

The nozzle head (2) is attached to the container (1) by a valve stem (6). Nozzle head <2> has two parts,
That is, the inner knee, the needle member (9) and the needle member (
The outer nozzle control member (10) is rotatably mounted on the outer nozzle control member (10).
). The needle member (9) has an externally threaded cylindrical part (11) having a hole (12) at one end that is press-fitted into the valve stem (6) and fixes the nozzle head to the container (1), and a cylindrical part (11).
) and a conical portion (13) provided at the other end. The hole (12) of the cylindrical part (11) is stepped at the inner end;
Next, a right-angled hole (14) is formed in the conical part (13), and a third
It terminates in an opening in the side wall of the conical section as shown in more detail in the figures. The control member (10) has a through hole. This through hole has an internally threaded cylindrical portion (12) that rotationally engages with the externally threaded cylindrical portion (11) of the needle member (9), and an inclination angle that corresponds to the conical portion (13) of the needle member (9). Convergent part (17
) and an enlarged end (18), and the cylindrical part (12) is provided with a recessed part for receiving the sealing ring (16). The control member (10) is centered around the needle member (9).
By rotating the , a conical space having a predetermined width is formed between the conical part (13) of the needle opening (9) and the widened end part (18) of the through hole, and a conical space is formed with a predetermined width through which the propellant passes. A cross-sectional annular nozzle (19) [FIG. 3] is formed. When the dispensing device is not in use, further rotation of the control member (10) about the needle member (9) completely closes the conical space 1, i.e. the nozzle, as shown in FIG. Prevent escape. Control 81i1<10

8). The axis of the screw hole (21) extends at an acute angle to the central axis of the through hole of the control member (10). This threaded hole (21) has an externally threaded turnip 1 which forms a container for the liquid to be sprayed. /Shuku22) is screwed up. Projecting from the inner end of the capsule (22) is a pointed tip (23) of a wick which extends into the liquid within the capsule and, if desired, allows the capsule to be completely viewed and the entire volume of liquid to be detected. accommodate. The chip (23) is a control member (
The intrusion nozzle (19) of the enlarged part (18) of the through hole (10)
) extends in the flow path of the propellant through the In general, the tip (23) is inserted into the path of the propellant by rotating the capsule (22) within the threaded hole (21) by means of a knurled wall (24) provided at the outer end of the capsule (22). It is possible to advance and retreat. A small opening (25) is provided in the wall near the outer end of the capsule (22), so that as liquid exits the capsule (22), air flows into the interior of the capsule through the opening (25) and Preventing a vacuum from forming inside. This opening (
Similar effects can be achieved by using a grooved core instead of 25).

Finally, a cap (26) is fitted onto the outer end of the control member (10) when the device is not in use.

When using a device that has been stored with the nozzle head facing upward, the cap (26) is removed and the control section If (10) is rotated around the needle member (9) to open the nozzle orifice (19). Set the width to the required width, and insert the screw hole (2
1) Rotating the capsule (22) within the chamber further adjusts the position of the tip (23) with respect to the propellant flow. After making such adjustments, the device is held in the same manner as a conventional pen by inverting the nozzle head downwards. By manually tilting the nozzle head (2), the valve stem (6) also tilts, and the tilting valve (5) operates, pumping the gaseous propellant through the V-tube (7), the valve (5), and the valve. It enters the conical space between the cone 811 (13) and the control member (10) through the shaft (6) and the hole (14) in the conical part of the needle member (9) and then through the nozzle (19). (forms a jet,
This jet flows into the core tip (23) of the capsule (22).
! i hit. The liquid to be sprayed is drawn into the wick tip at Jζ by the Bernoulli effect exerted by the high pressure propellant flow passing over the tip (23) and capillary action aided by gravity. the liquid is atomized from the tip (23) to an area (27) slightly beyond the tip (23);
The atomized liquid is directed onto the receiving surface by a flow of propellant.

The width of the nozzle (19), i.e. the flow rate of propellant, and the position of the tip of the wick with respect to the flow of propellant are individually adjustable, so that while the pen is moved to create the desired pattern, the pen Manual adjustment is possible by simply tilting the nozzle head with your hand to open and close the propellant gas supply. Therefore, the device is simple to use and easy to handle even for beginners.

Furthermore, the ability to vary a number of factors (propellant flow rate and delivery time as well as the width of the nozzle tip with which the propellant stream impinges) makes the device useful as a marking and coloring instrument in the field of graphic and fine art. A very wide range of effects can be achieved when used. Very precise effects are achieved by forcing the propellant stream to impinge only on the tip of the wick. Furthermore, it is also possible to replace the liquid to be sprayed with another liquid, e.g. to replace a liquid of one shade with a liquid of another shade, by removing one capsule (22) from the screw hole (21) and containing the other shade. This can be done quickly by replacing the capsule with another capsule.

The device does not require cleaning between color changes even when using different colored liquids since the liquid (at least in theory) does not come into contact with any parts of the device except for the container and wick.

The conversion of empty capsules (23) is extremely simple.

The flow of propellant gas through the A-refrigerator (19) and the adjustment of the tip (23) with respect to the flow of propellant gas can be effected by rotating the control member (10) and the capsule (22); In this case, it is convenient to provide a school and a pointer to indicate the opening degree of the A-rifice and the position of the tip of the core, if desired. Even when using liquids at a relatively high temperature of 8 degrees Celsius, there is no risk of clogging the device if the liquid can be transferred to the wick.

It is also possible to provide a locking means to prevent the nozzle head from suddenly tilting when the device is temporarily left with the nozzle open.

From the above description, it is possible to make various modifications to the configuration of the dispensing and atomizing device. For example, it is unnecessary to use a container of propellant that forms part of the pen. A separate propellant source may also be used, in which case the propellant source is attached to the nozzle head through suitable piping. The nozzle head is attached to an elongated body containing a manually operated valve that regulates the propellant supply. In this case, the propellant source is a near compressor, compressed air cylinder, or other compressed gas cylinder, or 'FREON'.
It can be composed of a liquid propellant container such as ``.

In the illustrated embodiment, when the propellant in the container (1) is empty, the container (1), the valve (5) and the valve stem (6) pull out the head from the valve stem (6). By doing so, it can be easily removed as a single unit. However, since the entire device is constructed from relatively inexpensive materials, it is common to discard the container (1) when the propellant is emptied. Alternatively, a refillable container may be used if desired.

Although it is convenient to use a tilting valve as valve (5), it is not a requirement. It is sufficient to use other types of valves, such as valves that can be easily actuated by pressing or sliding a button or other device with the finger.

In some cases, the nozzle opening can be fixed to a predetermined area. In this case, the control member (10) is fixed relative to the needle member (9). Similarly, the capsule (
22) is also permanently fixed to the head.

The type of dispensing device shown is one dispensing device and a quantity of water- or alcohol-based dyes or colorants, etc.
Compatible capsules (22) each containing a liquid
It is preferable to use it in a kit consisting of. For each shade, two or more core chips with different widths may be prepared. By using such Kira 1, you can achieve extremely high coloring from a wide range of colors! A wide range of working effects can be achieved, including coloring of dense spots. The device of the present invention can also be used in capsules in which each capsule contains a different type of drug or perfume.

Another arrangement is that the container is accommodated in the nozzle head to form a gap between the container itself and the needle member (9), with the tapered end of the wick extending from the end of the conical portion (13). The contour may be such that it acts as a central needle portion of the nozzle.

In this case, the propellant emerges as a converging stream from an annular nozzle surrounding the core tip or from a plurality of independent A rifices surrounding the core tip, and impinges on the core tip in two or more strips. The propellant flow can be created to create a ``double spray'' or ``multispray'' effect to form a wide range of spray patterns.

FIG. 4 shows another embodiment of the present invention.

This embodiment is a stand-alone dispensing device in which the liquid to be dispensed is contained in a chamber formed in the nozzle head rather than in a separate turnip hill.

Like the embodiment shown in FIGS. 1-3, the embodiment of FIG. 4 also features an elongated container (30) containing pressurized propellant and a nozzle head (31). The container (30) has a structure similar to that shown in FIGS. 1 to 3, and the container (30)
The end of the valve includes a tilt-operated valve of known construction and has a protruding valve stem (

50) Preferably, the nozzle head 1 extends over the edge of the container (30) to prevent the nozzle head 1 from tilting relative to the container. By tilting the lever, the tilting valve (32) is actuated. This allows compressed air or other debris to be removed from the container (
30), passes through the hole (35) and exits the nozzle [1 (3).
6) emits a high-speed jet. This jet impinges on the tip (49) of the wick (49) to form an atomized liquid spray, which is ejected through the open end of the recess (43). At the same time, liquid is drawn into the wick from the wad in the annular chamber (44), so that a continuous atomized spray is formed as long as the valve (32) is activated and the liquid supply continues. - When the container (30) becomes empty, the valve stem (33) must be pulled out from the end of the hole (35) and the valve stem of a new container inserted (thus, it is possible to replace the valve stem (33)). Similarly, to supply liquid to the annular chamber (44), the central member (
34) from the outer member (39) and replacing the empty wadding with a new wadding.

This type of liquid dispensing and atomizing device is suitable for use in applications consisting of a plurality of devices, each containing a liquid of a particular color. As in the embodiment of FIGS. 1-3, the device allows the container (32) to be discarded when empty or to replace the old container with a new container. Annular chamber (4

A wick (118) extends through an orifice in the lower end wall of 8). The core (118) is formed from an absorbent material, preferably a fibrous material. The upper end of the wick is immersed in the liquid within the capsule (113), while the lower end of the wick is formed into a point. At least one groove is provided on the side surface of the wick, through which air flows into the capsule (1
13) converting the liquid that enters and is drawn from the capsule through the wick.

When the device is not in use, the knob (1ie) is attached to the head (103).
Move the capsule (113) until it touches the top surface of the chamber (108).

And particulates are discharged from the device through h9 outlet J--7 (111), which is disposed inside the unit (108).

At the same time, liquid is drawn further into the wick tip by the aerodynamic action of the jet and gravity-assisted capillary action. Since the amount of propellant gas released with each actuation of the actuation button is determined by setting the cylindrical volume valve, the amount of liquid dispensed with each button actuation is similarly metered.

The apparatus shown in FIG. 9 makes it possible to form finely divided sprays with a particle size of less than 5 μm, which are necessary for the administration and dispensing of many medicinal solutions, especially inhaled medicinal solutions.

Although the apparatus of Figure 9 is particularly suitable for dispensing pharmaceutical liquids, it can also be used for dispensing other liquids, such as perfumes, which require a finely divided spray.
