Hereinafter, the present invention will be described based on embodiments shown in the drawings.
(First embodiment)
1 to 15 show a portable liquid ejecting apparatus 1 used in the first embodiment of the present invention.
The portable liquid ejecting apparatus 1 used in the present embodiment is composed of two ejecting apparatuses 10 and a portable launching apparatus 20 on which these two ejecting apparatuses 10 are mounted.

First, the two injection devices 10 will be described.
As shown in FIG. 3, the two injection devices 10 inject the liquid injection material 12 from the container 11 by pressing the liquid injection material 12 according to the present embodiment and the liquid injection material 12. A piston 13 for generating a gas, a non-explosive pyrotechnic gas generator 14 for generating a gas pressure for pressing the piston 13, a nozzle portion 16 for ejecting a liquid propellant 12 pressed by the piston 13, a nozzle portion 16 and a container 11, and an adapter 17 that connects the nozzle portion 16 and the adapter 17.

The liquid propellant 12 according to the present embodiment includes, for example, a tearing liquid having a viscosity of about 6 to 40 dPa · s, a marking liquid, and the like. Since the liquid propellant 12 is viscous, the liquid propellant 12 is jetted in a lump, hardly diffuses, and the jetting distance becomes long.
The tear solution is made into a viscous tear solution by dissolving a tear component in ethanol, mixing water, and adding a gelling agent. Examples of the lacrimatory component include 2-chloroacetophenone, capsaicin, chili extract, and allyl isothiocyanate. Examples of the gelling agent include xanthan gum, sodium carboxymethyl cellulose, guar gum, pectin, carrageenan, propylene glycol, tamarind gum and the like.

  The marking liquid includes a case where the paint is viscous, a case where the paint is not viscous (water dilutable), a case where the paint is not viscous (ethanol dilutable), and the like. If the paint is viscous, use it as it is within the viscosity range. When the paint is not viscous (dilutable with water), the paint is diluted with water and a gelling agent is added to obtain a viscous marking liquid. When the paint is not viscous (ethanol can be diluted), the paint is diluted with ethanol, mixed with water, and a gelling agent is added to form a viscous marking liquid. Examples of the paint include ultraviolet light-emitting paint, fluorescent paint, phosphorescent paint, paint, and ink. Examples of the gelling agent include xanthan gum, sodium carboxymethylcellulose, guar gum, pectin, carrageenan, propylene glycol, and tamarind gum.

The container 11 filled with the liquid propellant 12 is made of, for example, a cylindrical body made of metal such as stainless steel or aluminum, and is provided with a female screw portion 11a into which a non-explosive pyrotechnic gas generator 14 is screwed at one end portion. A female screw portion 11b into which the adapter 17 is screwed is provided at the other end portion.
The piston 13 includes, for example, a main body 13a having a cylindrical shape made of plastic such as Teflon (registered trademark), ABS resin, nylon resin, and the like, and a pressure release groove 13c provided on the front end portion 13b side that presses the liquid spray 12. And a pressure receiving recess 13e provided on the rear end 13d side in contact with the gas outlet of the non-explosive pyrotechnic gas generator 14. The container 11 is attached to the inner wall surface 11c on the inner side of the female screw portion 11a at one end portion.

  As shown in FIGS. 3 and 4, the non-explosive pyrotechnic gas generator 14 includes a gas generator 14 a and a metal cylindrical body made of, for example, stainless steel or aluminum, and accommodates the gas generator 14 a. The holder 14o, and the leg wires 14j1 and 14j2 connected to the bridge 14g and 14g2 connected to the bridge wire 14g are fixed with epoxy resin, and the leg wires 14j1 and 14j2 connected to the cable bridge 14g are connected to the holder 14o. For example, a wedge base 14n made of a hard resin such as nylon resin or a metal such as stainless steel or aluminum, and a bottomed cylindrical body made of a metal such as stainless steel or aluminum, and covering the wedge base 14n. The cap 14k is screwed into the holder 14o by a female screw portion 14m provided on the inner periphery of the opening end.

  For example, the gas generating unit 14a is filled with a gas generating agent 14c in a gas generator tube 14b made of a metal bottomed cylindrical body made of aluminum, and an igniter cup 14d, an igniting agent 14e, and an igniting agent. The holder 14f and the plug 14g with the bridge line are sequentially loaded, and the gas generator tube body 14b is formed by caulking processing at the site 14h of the igniter holder 14f and the site 14i of the plug 14g with the bridge line.

  For example, by using a soft metal material such as aluminum, the gas generator tube 14b can easily destroy the gas generator tube 14b due to the reaction heat and reaction gas pressure of the gas generating agent 14c which is a non-explosive composition. Can be transmitted to the outside. The gas generator tube 14b may be anything as long as it is a soft metal material with good workability. For example, since the gas generator tube 14b has the same shape as an electric detonator using copper, aluminum (for example, A1-6016-0) is used. By using it, the confusingness is removed. The aluminum gas generator tube 14b is alumite-treated on the inner and outer surfaces.

  The gas generator tube 14b is filled with a gas generating agent 14c in a range of 0.3 g to 0.5 g. This gas generating agent 14c uses a low-vibration and low-noise crushing chemical gunsizer (trade name, manufactured by Nippon Koki Co., Ltd.). This is a consumption permit in exactly the same way as the crushing method using explosives. It is a non-explosive crushing composition that crushes bedrock and the like without need. This non-explosive crushing composition is disclosed, for example, in JP-A-11-029389. The gas generating agent 14c is not for the purpose of crushing the bedrock or the like, but for changing the gas pressure to the purpose of injecting the liquid propellant 12, and as a result, the gas pressure of the gas generating agent 14c is made uniform by adjusting the particle diameter of the gas generating agent 14c. It was found that the variation can be reduced. Further, it is possible to change the dose of the gas generating agent 14c in accordance with the performance of flying an object.

  The gas generating agent 14c is composed of 11.5 parts by weight of aluminum, 38.5 parts by weight of cupric oxide, a thermite agent comprising 50 parts by weight of potassium alum or ammonium alum, and a chloride previously dissolved in acetone. It is constituted by putting 1.5 parts by weight of vinyl powder in the same container, adding an appropriate amount of acetone and mixing well. When acetone is almost volatilized and solidified, it is granulated with an 8-mesh sieve and dried. After drying, 2.5 parts by weight of potassium stearate as a blunting agent and an appropriate amount of acetone are added and slowly mixed, and when acetone is vaporized and solidified, it is granulated and dried to obtain a gas generating agent. As the gas generating agent 14c, a sieved product having 24 Tyler mesh passing 42 Tyler mesh stopping is used. That is, the particle size is adjusted in the range of 0.35 mm to 0.71 mm.

  In the gas generator tube 14b, a capsule-shaped igniter cup 14d made of a synthetic resin, which serves as a partition wall, is disposed to prevent mixing of the filled gas generant 14c and igniter 14e. The igniter cup 14d may be metal or non-metal, but since the metal material is good electric, the electric ignition signal does not flow to the bridge line 14t, but is expended on the discharge energy. Since 14e may be non-ignited, it is necessary to perform an insulating process (for example, anodized process).

  The igniter cup 14d is a thin film having a thickness of 0.1 mm or less and a half-cut capsule is used, and is inserted into the igniter holder 14f. In the igniter cup 14d and the igniter holder 14f, an igniting agent 14e composed of a non-explosive composition and an electric bridge wire (for example, a platinum-iridium wire) 14t of a plug with wire bridge 14g are arranged. The igniting agent 14e was boron / cupric oxide = 10 wt% to 20 wt% / 80 to 90 wt%.

The plug 14g with bridge line is inserted after the igniter holder 14f is inserted into the igniter cup 14d and the igniter 14e is filled in the range of 0.06g to 0.13g, and then the gas generating agent 14c is filled. A gas generator tube body is formed by press-fitting into a gas generator tube body 14b made of aluminum and forming two crimped portions (14h, 14i) from the outside of the gas generator tube body 14b made of aluminum. It is fixed to 14b. The gas generator tube 14b, which is crimped to a plug 14g with a bridge, is inserted into the wedge base 14n and filled with an epoxy resin 14u. Backward gas ejection when the gas generator 14a ignites is blocked by the epoxy resin 14u filled in the wedge base 14n.
Further, the leg lines 14j1 and 14j2 are taken out from two holes 14v vacated at the bottom of the wedge base 14n to form electrical contact portions. The wedge base 14n is provided with a wedge portion 14w to which leg lines 14j1 and 14j2 are attached and coupled to a socket 22c described later.

  The holder 14o has an inner wall portion 14p having a gas jet port 14q attached to the gas generating portion 14a and expanding toward the opening side, and a male screw portion 14r provided on the outer periphery of the opening end on the gas jet port 14q side. A male screw portion 14s that is screwed with the female screw portion 14m of the cap 14k is provided on the outer periphery of the opening end on the cap 14k side. For example, iron or stainless steel can be used as the material of the holder 14o, but aluminum A5056 is preferable in terms of weight reduction and cost. Since the holder 14o engages the male screw portion 14s with the female screw portion 14m of the cap 14k, the gas generating portion 14a is fixed by the holder 14o and the cap 14k, and the gas generating portion 14a is moved backward when the gas generating portion 14a is operated. Prevents jumping out.

The nozzle portion 16 is constituted by a one-hole straight-advancing nozzle made of a metal such as stainless steel or aluminum, or a hard resin such as ABS resin or nylon resin, and the nozzle 16a has a hole diameter of φ1.5 mm to 3 mm. Is provided with a male screw portion 16b for connection to the adapter 17.
The adapter 17 is made of, for example, a cylindrical body made of metal such as stainless steel or aluminum, and is provided with a male screw portion 17a to be screwed into the female screw portion 11b of the container 11 at one end portion, and a male screw of the nozzle portion 16 at the other end portion. A female screw portion 17b into which the portion 16b is screwed is provided. Further, the adapter 17 is provided with an annular piston receiving surface 17c that protrudes from the inner wall surface toward the center, and serves as a wall surface on which the piston 13 collides. The wall surface on the nozzle portion side of the piston receiving surface 17c is sealed so that the liquid ejected matter 12 does not leak when the nozzle portion 16 is attached, for example, from an aluminum seal, an aluminum plate, a grooved synthetic resin sheet, or the like. It is set as the contact surface which interposes the seal 18 which becomes.

Next, the portable launcher 20 will be described.
The portable launching device 20 has a container shape in which the outer shape can be made portable by connecting, for example, a split case 21A, 21B made of an injection molded product such as ABS resin or polyacetal resin with a plurality of screws 21a. ing.
The case 21 </ b> A has two attachment portions 22 that attach the two injection devices 10 in an exchangeable manner by exposing the nozzle portion 16, and a power supply portion 23 that supplies electric power to each of the injection devices 10 attached to the two attachment portions 22. And a power supply unit that is provided between the power supply unit 23 and the injection device 10 and that short-circuits the power supply unit 23 and the injection device 10, and the power supply unit 23 and the switch unit 24 are attached and communicated with the attachment unit 22. Circuit board 25.

The attachment portion 22 includes socket assembly portions 22a and 22b in which sockets 22c and 22d that are coupled to the wedge base 14n of each injection device 10 are assembled, and a partition wall portion that rises oppositely so as to restrain the side portion of each injection device 10. 22e, an O-ring 22f for fixing the distal end side portion of the container 11 of each injection device 10, and an adapter 17 of each injection device 10, and an insertion hole 28 of each injection device 10 exposing the nozzle portion 16 is provided. And a recess 22g to be formed.

As a result, the gas generator tube 14b is broken and the gas pressure is released. As shown in FIG. 13A, the released gas pressure pushes the piston 13, and the piston 13 pushes the liquid propellant 12 and pushes it. The liquid ejected material 12 thus broken breaks the seal 18 and is ejected to the outside from the nozzle 16a.

On the other hand, after the switch unit 24 energizes the other injection device 10, the program of the switch circuit is switched to the one injection device 10 side.

As shown in FIG. 28, this sighting device has a convex portion 121l as a target position, and the upper surface of the convex portion 121l and the upper surface of the concave portion 121k are in a straight line, thereby aiming at the top and bottom, and the center of the concave portion 121k. Since the convex part 121l comes to the left and right, it is possible to aim at the left and right.

Next, the operation of the portable liquid ejecting apparatus 100 used in this embodiment will be described.
First, assembly of the portable liquid ejecting apparatus 100 used in this embodiment will be described.

The positive female terminal 122c1 is connected, and similarly, the negative male terminal 114v of the wire mount plug 114k and the female terminal 122c2 on one side of the wire mount sockets 122a and 122b are connected. Further, the protrusion 114y of the wire mount plug 114k enters the hole 122c3 of the wire mount sockets 122a and 122b and is fixed.

As described above, the assembly of the portable liquid ejecting apparatus 100 is completed by attaching the two ejecting apparatuses 110 to the portable launching apparatus 120.
The portable liquid ejecting apparatus 100 allows the user to operate the switch 124a on the nozzle unit 116 side of the projecting apparatus at any time. In order to prevent erroneous operation, the safety cover 126 is attached to the switch 124a and the nozzle part 116 side.

The gas generated by combustion burns the gas generator tube 114b, releases the gas pressure, the released gas pressure pushes the piston 113, the piston 113 pushes the liquid propellant 112, and the pushed liquid The ejected matter 112 breaks the cup 117, breaks the sealing seal 118, and is ejected to the outside from the nozzle 116a.

Here, the force for breaking the cup 117 is about 1 to 3 kgf, and the force for breaking the sealing seal 118 is about 0.5 kgf.
When the piston 113 reaches the pressure release portion 111e of the container 111 during the above-described operation, the gas pressure passes through the gap between the pressure release portion 111e and the piston 113, and the residual pressure is released to the outside.
On the other hand, in the switch unit 124, after energization of one injection device 110, the program of the switch circuit is switched to the other injection device 110 side.

In this state, when the user presses the switch 124a again, the other injector 110 is energized, the current of the battery 123a passes through the leg lines 114j1 and 114j2, and the non-explosive pyrotechnic gas generator 114 is energized. The bridge line 114t is energized, the bridge line 114t generates heat, the igniting agent 114e is ignited, the gas generating agent 114c is combusted by the ignition of the igniting agent 114e, and the generated gas breaks the gas generator tube 114b. The gas pressure is released, the released gas pressure pushes the piston 113, the piston 113 pushes the liquid propellant 112, the pushed liquid propellant 112 breaks the cup 117, breaks the sealing seal 118, and the nozzle 116a From outside.
On the other hand, after the switch unit 124 energizes the other injection device 110, the program of the switch circuit is switched to the one injection device 110 side.

As described above, the portable liquid ejecting apparatus 100 used in the present embodiment can perform the ejection of the liquid ejected matter 112 twice against the suspicious person X, and thus can self-defense. .
Therefore, as shown in FIG. 28, the liquid jet is obtained by the user Y aiming up, down, left, and right by making full use of the convex part 121l and the concave part 121k constituting the sighting device provided in the portable launching device 120. 112 injections are more accurate and can be self-defending.
And after using the two injection devices 110, the two used injection devices 110 are extracted from the portable launch device 120, and the new injection devices 110 are respectively mounted on the portable launch devices 120.

As shown in FIG. 27, the ejection device 110 is removed from the portable launcher 120 by holding the release button 121g of the portable launcher 120 and holding the nozzle portion 116 of the ejection device 110. This is accomplished by pulling it out of the portable launcher 120.
As shown in FIG. 26, by pushing the release button 121g, the claw portion 114x of the wire mount plug 114k of the injection device 110 is pushed, and the convex portion 114y of the wire mount plug 114k becomes the wire mount of the portable launch device 120. The sockets 122a and 122b are removed from the holes 122c3. The injection device 110 can be extracted from the portable launch device 120 by pulling out the injection device 110 in this state.

The injection device 110 can be attached to the portable launching device 120 by attaching a Δ seal 119 attached to the container 111 of the injection device 110 and a Δ portion provided near the insertion hole 128 of the portable launching device 120. The injection device 110 is inserted into the insertion hole 128 of the portable launching device 120 while keeping the vertex position of 129 aligned.
Thereby, the portable liquid ejecting apparatus 100 used in the present embodiment can be put into a usable state again.
The battery 123a is replaced by removing the screw 121a and removing the case 121B from the case 121A.

Next, in the portable liquid ejecting apparatus 100 used in the present embodiment, the optimum conditions for the clearance between the piston 113 (outer diameter, length, groove size) and the container pressure release portion (inner diameter, inner diameter length) were examined.
In the present embodiment, the function of the adapter 17 in the first embodiment is added to the container 111, and the container 111 is a single component having a pressure release portion 111e, so the piston in which the pressure release mechanism in the first embodiment functions. 13 and the adapter 17 are the same result.
Therefore, also in this embodiment, the same result as the first embodiment could be obtained.

  In the above-described embodiment, the case where the pressure release mechanism that releases the gas pressure from the nozzle portion 116 to the outside when the piston 113 collides is configured by the piston 113 and the pressure release portion 111e provided in the container 111 has been described. The present invention is not limited to this. For example, the present invention may be configured by forming a plurality of pressure release grooves connected to the inner wall of the pressure release portion 111e of the container 111 and the piston receiving surface 111d.

Although the case where the pressure release part 111e was provided in the container 111 was demonstrated in the said embodiment, this invention is not limited to this, For example, as shown in FIG. 30, the container 111 is adapter like 1st embodiment. 17 may be provided.
Moreover, although the said embodiment demonstrated the case where the coupling | bonding of the wire mount plug 114k and wire mount socket 122a, 122b was used for the coupling | bonding of the injection apparatus 110 and the portable launching apparatus 120, this invention is based on this. Not limited to this, as shown in FIG. 29, similarly to the first embodiment, the injection device 110 may be connected to the wedge base 14n and the socket 22c.

  Moreover, although the said embodiment demonstrated the case where a sighting device was comprised with the convex part 121l and the recessed part 121k, this invention is not restricted to this, For example, it replaces with the recessed part 121k by the side of a recessed part, as shown in FIG. It is also possible to provide two convex portions 121m and to aim at the convex portion 121z coming to the center of the two convex portions 121m. Further, as shown in FIG. 32, a ring portion 121n may be provided instead of the concave portion 121k, and the convex portion 121z may come to the center of the circle of the ring portion 121n to aim. Furthermore, as shown in FIG. 33, a laser pointer 121o may be attached to aim.

In the above embodiment, the case where the safety cover 26 or 126 is made detachable has been described. However, the present invention is not limited to this, and as shown in FIG. 34, it can be opened and closed by a hinge (not shown). A connecting member 126f connected to a hinge (not shown) may be provided so that it can be opened and closed by the hinge (not shown).
Moreover, although the case where the safety cover 26 or 126 was made detachable was described in the above embodiment, the present invention is not limited to this, and the safety cover 26 or 126 may be slid sideways.

In the first embodiment, xanthan gum (gelling agent) is added to the ink diluted with water, and the liquid diameter is adjusted according to the amount of addition, and the nozzle diameter is 1.5 mm to 3 mm. The case where the jetting material is jetted under the condition of the viscosity of 6 dPa · s to 40 dPa · s has been described.
The liquid propellant of the present invention is not limited to this. In the present invention, basically, as in the first embodiment, the case of water + action effect substance (such as ink) + gelling agent, and water + ethanol It is divided into the case of + active substance + gelling agent.

Hereinafter, the injection in this invention is demonstrated in detail.
First, the composition ratio in the case where the working effect substance is an edible dye and the solvent is only water and the composition ratio in the case of ethanol mixing will be examined.
(1) The basic requirements when the action-effect substance is an edible pigment will be described.
Since the gelling agent (sodium carboxymethylcellulose (hereinafter referred to as CMC)) and the food colorant are dissolved in water, a viscous propellant can be formed without mixing ethanol. In this case, the component composition requirements may be 1.3 wt% to 2.3 wt% of CMC, 0.01 wt% to 5 wt% of food coloring matter (action effect substance), and 92.7 wt% to 98.69 wt% of water. found.

(2) The advantages of mixing ethanol will be described.
Mixing ethanol produces the following advantages.
1) Decrease in freezing point Freezing point of ethanol: -117 ° C
2) Improvement of long-term storage stability Bactericidal effect by ethanol 3) Improvement of solvent volatility Because of the high volatility of ethanol, the effect of the effect substance after adhesion tends to appear more quickly.
4) Dispersion of water-soluble solid content (CMC, food coloring) In a state where the solid content is dispersed, water is added and dissolved to dissolve quickly.

The addition ratio of ethanol varies depending on the purpose (value) in the above 1) to 3).
On the other hand, in the above 4), there is a relationship with the manufacturing method of the injection, and it is as follows.
In the method for producing a propellant according to the present invention, when a water-soluble solid content (CMC, food coloring) is added to water or an aqueous ethanol solution, the solid content becomes a lump (Production Method 1 or Production Method 2 described later). It shows that efficiency is bad. As a method for avoiding this phenomenon, the water-soluble solid content is dispersed in ethanol and then water, which is a solvent for the water-soluble solid content, is added to dissolve the water-soluble solid content in a short time. The minimum mixing ratio of ethanol required to disperse the water-soluble solid content is the minimum composition ratio of ethanol when the solvent is an ethanol aqueous solution.
The minimum composition ratio of water-soluble solids is 1.3 wt% CMC and 0.01 wt% food color, and the ratio of ethanol required to disperse it in ethanol before adding water is the same as that of water-soluble solids. It was thought that it was necessary to have the same volume, and trial manufacture shown in Table 5 was performed.

※ＣＭＣ＋食用色素＝１．３ｇ＋０．０１ｇ≒２．５ｃｃ
２．５ｃｃ×０．７９ｇ／ｃｃ≒２．０ｇ

* CMC + food color = 1.3g + 0.01g ≒ 2.5cc
2.5cc × 0.79g / cc ≒ 2.0g

In Table 5, at level 2, the dispersion in ethanol was not sufficient and the dissolution time after adding water was long.
Therefore, the component composition requirements when the solvent is water and ethanol (dispersion medium) are as shown in Table 6.

※水の下限割合及びエタノールの上限割合は、後述する「エタノール水溶液の水とエタノールの割合検証」による

* The lower limit ratio of water and the upper limit ratio of ethanol are based on “Verification of ratio of water and ethanol in ethanol aqueous solution” described later.

Next, the composition ratio in the case where the working effect substance is ink or water-based fluorescent paint when the solvent is only water and the composition ratio in the case of alcohol mixing will be discussed.
(1) Basic requirements when the effect substance is ink or water-based fluorescent paint CMC and water-based fluorescent paint are soluble in water and insoluble in ethanol. Moreover, since the ink is dissolved in water and ethanol, a viscous propellant can be formed without mixing ethanol. In this case, the component composition requirements are CMC 1.3 wt% to 2.3 wt%, ink or water-based fluorescent paint (active effect substance) 1 wt% to 12 wt%, and water 85.7 wt% to 97.7 wt% by experiment. There was found.

(2) Advantage by mixing ethanol It is completely the same as the advantage by mixing ethanol mentioned above, The ratio was verified similarly. Table 7 shows.

※ＣＭＣ＋墨汁又は水性蛍光塗料＝１．３ｇ＋１ｇ≒３．５ｃｃ
３．５ｃｃ×約０．７９ｇ／ｃｃ≒２．８ｇ

* CMC + black ink or water-based fluorescent paint = 1.3g + 1g ≒ 3.5cc
3.5cc x about 0.79g / cc ≒ 2.8g

In Table 7, at level 2, the dispersion in ethanol was not sufficient and the dissolution time after adding water was long.
Therefore, the component composition requirements when the solvent is water and ethanol (dispersion medium) are as shown in Table 8.

※水の下限割合及びエタノールの上限割合は、後述する「エタノール水溶液の水とエタノールの割合検証」による

* The lower limit ratio of water and the upper limit ratio of ethanol are based on “Verification of ratio of water and ethanol in ethanol aqueous solution” described later.

Next, verification of the marking effect will be described.
(1) Since the viscous propellant to which 2-chloroacetophenone (hereinafter referred to as CN) is added as a lacrimatory component as an action-effect substance is colorless and transparent, after the propellant is ejected, the operator It was necessary to be able to judge whether it adhered. As a countermeasure, coloring means was used. In coloring, it is necessary to set the composition ratio, and similarly, the case of only food color not adding CN as an effect substance is also set.

When adding a marking effect to a viscous propellant, the addition ratio of food dyes to be added is verified.
A white target is placed 4 m ahead of the effective range of the portable liquid jetting device shown in this use example using a red food as a food coloring, and the ratio of the red food added is changed. From this, it was evaluated whether or not it could be visually confirmed whether or not it adhered.
A wide variety of colors and patterns can be considered as targets, but here we wanted to obtain the minimum necessary ratio of food coloring, so we decided to use a completely different white from the coloring.
The composition of the projectile at that time is as shown in Table 9.

評価結果の表し方は、付着したことを視認できたものを○、付着したことを視認できなかったものを×とした。
その結果を表１０に示す。

The evaluation result was expressed as “◯” when it was visually recognized that it was adhered, and “X” when it was not visually recognized that it was adhered.
The results are shown in Table 10.

As is clear from Table 10, all the three testers were able to visually recognize even the lowest 0.01 wt% tested this time.
Therefore, the lower limit of the addition ratio of the food coloring is 0.01 wt%.
On the other hand, when the upper limit is 3 wt% or more, there is no great difference in color strength, and it is economically not preferable to increase the amount of food color that is higher than that of an aqueous ethanol solution that is reduced when the amount of food color is increased.
Therefore, the upper limit of the addition ratio of the edible dye is 5 wt%, preferably 3 wt%.
(Reference: food red 40,000 yen / kg, CMC 4,000 yen / kg, ethanol aqueous solution 1,500 yen / kg)
Therefore, the addition ratio of the food coloring is 0.01 wt% to 5 wt%.

(2) The viscous propellant to which CN is added as a working effect substance was colorless and transparent. Therefore, it was necessary to be able to determine whether the operator adhered to the target object after the propellant was injected. It was. As a countermeasure, coloring means was used. In coloring, it is necessary to set the composition ratio, and similarly, it is also set only in the case of ink or water-based fluorescent paint without adding CN as an effect substance.
When a marking effect is added to a viscous jetted product, the addition ratio of black ink or water-based fluorescent paint to be added is verified.

A white target is placed 4 m ahead of the effective range of the portable liquid ejecting apparatus shown in this use example for the jet liquid in which the ink or water-based fluorescent paint (yellow) addition ratio is changed. It was evaluated whether or not it could be visually confirmed whether or not it adhered.
The target may be a wide variety of colors and patterns, but here, since the minimum required ratio of ink or water-based fluorescent paint is desired, it was set to be completely different from the pigment.
The composition of the projectile is as shown in Table 11.

The evaluation result was expressed as “◯” when it was visually recognized that it was adhered, and “X” when it was not visually recognized that it was adhered.
The results are shown in Table 12.

All three testers were able to see even the lowest 1.0 wt% tested this time.
Therefore, the lower limit of the addition ratio of black ink or water-based fluorescent paint is 1 wt%.
On the other hand, with respect to the upper limit value, 10 wt% or more is not much different in the color intensity, and if the ink or water-based fluorescent paint is increased, the amount of ink or water-based fluorescent paint whose unit price is higher than the ethanol aqueous solution to be reduced is not increased. Economically unfavorable.
Therefore, the upper limit of the addition ratio of black ink or water-based fluorescent paint is 12 wt%, preferably 10 wt%.
(Reference: Indian ink 1,800 yen / kg, aqueous fluorescent paint: 5,600 yen / kg, CMC 4,000 yen / kg, ethanol aqueous solution 1,500 yen / kg)
Therefore, the addition ratio of ink or water-based fluorescent paint is 1 wt% to 12 wt%.

Next, the amount of CN added when a tearing effect is added to a viscous propellant is verified.
One drop of the propellant with varying CN addition amount was attached to the human mucosa (tongue), and the time until irritation was sensed, the degree of irritation, and the time until irritation subsided were measured. When irritation was felt, it was washed away with water. Since the test with the eyeball is difficult, the test was performed on the tongue, which is a mucous membrane part, and the ejected matter can be easily removed.
Table 13 shows the composition table of the test spray. The results are shown in Table 14.

Regardless of the amount of CN added, a strong irritation was felt as soon as it adhered (less than 1 second).
After the stimulus was sensed, it was washed away with water immediately, but it took time until the stimulus subsided. The greater the amount of CN added, the longer the recovery time.
From the above results, when the CN addition ratio is 0.1 wt%, the recovery time is short, but the sensing time and the degree of stimulation are sufficient, and this is the lower limit of the addition ratio (0 wt% is ineffective) .
In addition, regarding the upper limit of the CN addition ratio, commercially available tear sprays using CN are 1 wt% to 2 wt% (reference: Japan poisoning information center, HP for members, summary information on tears), If it is the lower limit of this, it will be considered that there is little influence on a human body, and 1 wt% was made into the upper limit.
Therefore, the CN addition amount was set to 0.1 wt% to 1 wt%.

Next, it verifies about the ratio of water and ethanol of ethanol aqueous solution.
First, the ratio of water and ethanol in an ethanol aqueous solution added to various (a tear solution, marking solution) viscous propellant is verified.
Therefore, the ratio of water and ethanol that can be produced by various viscous propellants (a to e) is obtained. Depending on the ratio of water and ethanol, CMC and action-effect substances (CN, food coloring, ink, water-based fluorescent paint) do not dissolve.
a: Viscous tear solution (CN added)
b: Viscous marking liquid (food colorant added)
c: Sexual marking liquid (addition of ink or water-based fluorescent paint)
d: Liquid with marking effect (addition of food coloring added) to viscous tear solution (CN added) e: Liquid with marking effect (ink ink or aqueous fluorescent paint added) added to viscous tear solution (CN added)

Explain the test results.
The ratio of water and ethanol that can produce various viscous sprays is shown. (Water + ethanol = 100 wt%)
FIG. 35 shows a: viscous lacrimal fluid (CN added) (CMC 1.3 wt% to 2.3 wt%, CN 0.1 wt% to 1 wt%, liquid temperature 20 ° C.).
CMC is soluble in water but insoluble in ethanol. CN is insoluble in water but soluble in ethanol.
For this reason, as is clear from FIG. 35, CMC is not completely dissolved when water is less than 54 wt%, and CN is not completely dissolved when water exceeds 61 wt%.
Further, when ethanol is less than 39 wt%, CN is not completely dissolved, and when it exceeds 46 wt%, CMC is not completely dissolved.
It was found that the ratios of water and ethanol for dissolving CMC and CN were 54 wt% to 61 wt% water and 39 wt% to 46 wt% ethanol.

FIG. 36 shows b: viscous marking liquid (food colorant added) (CMC 1.3 wt% to 2.3 wt%, food color 0.01 wt% to 5 wt%, liquid temperature 20 ° C.).
CMC is soluble in water but insoluble in ethanol. Food dyes are soluble in water and ethanol.
For this reason, as apparent from FIG. 36, CMC is not completely dissolved when water is less than 54 wt% or ethanol exceeds 46 wt%. Moreover, when ethanol was less than 2 wt%, CMC was not efficiently dissolved and it took time.
It was found that the ratio of water and ethanol for dissolving CMC and food coloring was 54 wt% to 98 wt% water and 2 wt% to 46 wt% ethanol.

FIG. 37 shows c: a viscous marking liquid (addition of ink or aqueous fluorescent paint) (CMC 1.3 to 2.3 wt%, ink or water fluorescent paint 1 wt% to 12 wt%, liquid temperature 20 ° C.).
CMC and water-based fluorescent paint are soluble in water but insoluble in ethanol. Ink is soluble in both water and ethanol.
For this reason, as shown in FIG. 37, when water is less than 54 wt% or ethanol exceeds 46 wt%, CMC and the aqueous fluorescent paint are not completely dissolved. Moreover, when ethanol was less than 2.8 wt%, CMC and the water-based fluorescent paint did not dissolve efficiently, and it took time.
It was found that the ratio of water and ethanol for dissolving CMC and ink or water-based fluorescent paint was 54 wt% to 97.2 wt% of water and 2.8 wt% to 46 wt% of ethanol.

FIG. 38 shows d: a solution obtained by adding a marking effect (addition of food coloring) to a viscous tear solution (CN addition) (CMC 1.3 wt% to 2.3 wt%, CN 0.1 wt% to 1 wt%, food coloring 0. (01 wt% to 5 wt%, liquid temperature: 20 ° C.).
CMC is soluble in water but insoluble in ethanol. CN is insoluble in water but soluble in ethanol. Food dyes are soluble in water and ethanol.
For this reason, as shown in FIG. 38, CMC will not melt | dissolve if water is less than 54 wt%, and CN will not melt | dissolve if it exceeds 61 wt%.
Further, when ethanol is less than 39 wt%, CN does not dissolve, and when it exceeds 46 wt%, CMC does not dissolve.
It was found that the ratios of water and ethanol for dissolving CMC and CN and food coloring were 54 wt% to 61 wt% water and 39 wt% to 46 wt% ethanol.

FIG. 39 shows e: a liquid obtained by adding a marking effect (inkbrush or water-based fluorescent paint addition) to a viscous tear solution (CN addition) (CMC: 1.3 wt% to 2.3 wt%, CN: 0.1 wt% to 1 wt%, black ink and water-based fluorescent paint: 1 wt% to 12 wt%, liquid temperature: 20 ° C.)
CMC and water-based fluorescent paint are soluble in water but insoluble in ethanol. CN is insoluble in water but soluble in ethanol. Ink is soluble in both water and ethanol.
For this reason, as shown in FIG. 39, CMC and the fluorescent paint do not dissolve when the water is less than 54 wt%, and CN does not dissolve when the water exceeds 61 wt%.
When ethanol is less than 39 wt%, CN does not dissolve, and when it exceeds 46 wt%, CMC and water-based fluorescent paint do not dissolve.
It was found that the ratios of water and ethanol for dissolving CMC and CN, ink, and aqueous fluorescent paint were 54 wt% to 61 wt% water and 39 wt% to 46 wt% ethanol.

Next, the wind resistance performance of the viscous projectile and the non-viscous projectile is verified.
For this purpose, as shown in FIG. 40, the target is placed at the tip of the position where the ejection device (portable liquid ejection device) is fixed indoors. A fan is installed diagonally behind the target, and the wind is sent to the spraying device. In the headwind, activate the spray device and verify that the spray is attached to the target.
In this test, the injection distance was 3 m and 4 m, and the wind speed was 3 m / s at the position of the injection device.
Table 15 shows the composition of the projectile.

The injection result is evaluated by ◯ × according to the state of attachment of the injection product to the target, and is shown in FIG. 41 and Table 16.
In FIG. 41, (a) shows the case of ◯: adhering in a circular shape, and (b) is adhering with x: dots. Or the case where it does not adhere is shown.

As shown in Table 16, when a non-viscous propellant is jetted in the head wind, it is diffused by the wind and does not adhere to the target.
Moreover, most of the projectiles are caused to flow toward the injector by the wind.
The viscous propellant adheres to the target without being diffused by the wind even when jetted in the head wind.
Therefore, it can be seen that the viscous jetted material has wind resistance and a longer injection distance.

Next, the ejection distance between the viscous tear liquid and the non-viscous tear liquid is verified (the ejection distance is verified by the CN intensity (index of arrival amount)).
Therefore, as shown in FIG. 42, a sampling container is installed at the tip of a position where the ejection device (portable liquid ejection device) is fixed indoors. The tear liquid is sprayed toward the sampling container, and the tear liquid is sampled (after the tear liquid is sprayed, the sampling container is immediately covered). The gas in the sampling container is analyzed by a gas chromatograph.
In this test, the sampling distance was 1 m, 2 m, 3 m, 4 m, and the sampling container size was 8 l (250 × W170 × H180 mm).
Table 17 shows the composition of the projectile.

As a result of the analysis, the waveform area of CN which is a tearing component in the sampling container was obtained. With this waveform area as the CN strength (an indicator of the amount reached), FIG. 43 shows the change in CN strength at each spray distance of viscous tear fluid and non-tear fluid.
Up to a spray distance of 3 m, both tear fluids have the same CN strength, but at 4 m, the CN strength of non-viscous tear fluid decreased by about 80 to 90%.
On the other hand, the viscous tear solution showed almost no decrease in CN strength even at 4 m.
Therefore, it was found that the jetting distance is longer in the case of a viscous jet.

Next, the manufacturing method of the injection thing concerning the present invention is explained.
Here, a method capable of easily producing a viscous propellant in a short time will be verified.
For the verification of the manufacturing method, from the following (1) to (7) viscous propellants, (1) a simple method for manufacturing a viscous tear solution is verified in a short time. The same manufacturing method is applied to the other spray liquids (2) to (7), and it is verified whether it can be manufactured in the same manner.
(1) viscous tear solution
(2) to (4) viscous marking fluid
(5)-(7) Liquid with marking effect added to viscous tear solution
Table 18 shows the compositions of the propellants (1) to (7).

Next, a manufacturing method will be described.
The production volume of viscous tear solution (1) is 400 ml, and three production methods are verified (working environment: 20 ° C.).
<Manufacturing method 1>
Ethanol is weighed, put into a container and stirred, and CN is weighed and put into it, stirred and dissolved. Water is weighed and added to it, and further stirred and mixed. Next, CMC is weighed, charged, heated to about 50 ° C. and stirred to dissolve the CMC to produce a spray.

<Manufacturing method 2>
Ethanol is weighed, put into a container and stirred, and CN is weighed and put into it, stirred and dissolved. On the other hand, water is weighed and put into a container, heated and stirred at about 50 degrees, and CMC is weighed and put therein, and stirred and dissolved.

An object of the present invention is to inject a projectile far away.
In the case of a conventional projectile, it is conceivable that the projectile is dispersed into small particles and receives a large air resistance as a reason why it cannot be ejected far.
As a solution, in the present invention, attention has been paid to suppressing the dispersion of the projectile by increasing the viscosity of the projectile.
The projectile is a liquid. About 90% or more of the components are water or an aqueous ethanol solution, each having a viscosity of about 0 dPa · s, and the problem cannot be solved as it is.
Therefore, a gelling agent was added to increase the viscosity.

First, it was confirmed how the viscosity changes according to the ratio of adding the gelling agent.
The result is the graph shown in FIG.
As the addition ratio of the gelling agent increased, the viscosity increased exponentially.
Then, the viscosity was increased and whether or not the projectile could be ejected far (whether or not) was evaluated using the confirmation criteria in the second embodiment according to the following criteria.
The case where it adhered to the circular shape shown in FIG.15 (C) evaluated that dispersion | distribution of the injection thing was suppressed.
The addition ratio of CMC, which is a result of good adhesion, is 1.3 wt% to 2.3 wt%, and the viscosity at that time is 6 dPa · s (20 ° C.) to 40 dPa · s (20 ° C.). I understood.
