Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a multi-discharge aerosol device. More specifically, the present invention relates to a multi-discharge aerosol apparatus that separates and stores two or more types of stock solutions, and uses them while being jetted and mixed at the same time.
[0002]
[Prior art]
  Conventionally, a two-component urethane in which a first liquid containing a polyol and a second liquid containing an isocyanate are filled in separate aerosol devices, and a conduit connected to the outlet of the aerosol valve of each aerosol device is connected to a common mixing tube. A foam manufacturing apparatus has been proposed (see Japanese Patent Application Laid-Open No. 58-16832). In this case, when the push button of each aerosol device is pushed and the valve is opened, both are combined together in a common passage and ejected from the ejection port in a mixed or mixed state.
[0003]
[Problems to be solved by the invention]
  The conventional two-component type aerosol apparatus needs to hold each aerosol apparatus in the left and right hands and operate each push button. For this reason, both hands are closed, and it is extremely inconvenient when, for example, a two-component hair dye is discharged onto a comb or the like. In addition, since the amount of operation of both push buttons can be adjusted, the mixing ratio of the first liquid and the second liquid can be finely adjusted. When pressing only strongly, only the first liquid or the second liquid is ejected, which is wasted. An object of the present invention is to provide a multi-discharge aerosol apparatus that can be operated with one hand and can eject two liquids simultaneously without much care.
[0004]
[Means for Solving the Problems]
  The multiple-discharge aerosol device of the present invention includes a pressure-resistant container body, a first stock solution and a propellant accommodated in the container body, and a first air attached to the container body and normally biased to a closed side. A first aerosol device comprising a sol valve and a passage leading from the outlet of the first aerosol valve to the jet outlet, a pressure-resistant container body, a second undiluted solution and a propellant contained in the container body, and the container body A second aerosol device that is attached to the second aerosol valve and is normally biased to the closed side by a return spring, and a passage leading from the outlet of the second aerosol valve to the jet port; Single operating means for operating the aerosol valve and the second aerosol valve at the same time, the discharge amount from the first aerosol valve, and the second aerosol valve And a means for balancing the volume, the means for the balance,When operating force is applied, the amount of operation is increased proportionally as the operating force increases, and even if the operating force is increased from the middle, the amount of operation does not increase so much, and then the amount of operation increases again. As the operation amount increases again, both the aerosol valves are opened,For the operator, the operating force of the operating means passes through a range of minute operating forces that cause a difference in the degree of opening of each aerosol valve, and reaches a strong operating level that provides an appropriate amount of opening. Means to hesitateHasIt is characterized by that.
[0005]
  In such a multi-discharge aerosol device, the passage of the first aerosol device and the passage of the second aerosol device are coupled to a common passage from the middle, and the first stock solution and the second stock solution are put together at the tip of the common passage. You may make it provide the common jet nozzle which spouts.
[0006]
  Means for balancingIsIn addition, an opening / closing mechanism may be further provided that always closes the passage or the spout and opens only when the operation amount of the operation means reaches a predetermined level. Further, the means for balancing may be provided with an opening and closing mechanism that always closes the passage or the outlet and opens only when the pressure on the aerosol valve side reaches a predetermined level..
[0007]
  in frontNotAs means for changing linearly, for example, a cam mechanism or a link mechanism can be used..
[0008]
[Operation and effect of the invention]
  In the apparatus of the present invention, when the operating means is operated, the first valve provided in the first aerosol device and the second valve provided in the second aerosol device are simultaneously opened, and two liquids can be ejected. That is, in the apparatus of the present invention, since the operation means is single, the operation of receiving the ejected matter with a comb or the like while operating the operation means with one hand is simple. In addition, when the first valve and the second valve are operated with a single operating means, depending on the operating state, only the amount of one of the undiluted liquid jets may increase.
  There are various reasons why the discharge amount from the first valve and the discharge amount from the second valve are lost and only the discharge amount from one side is increased. According to the inventor's investigation, the relationship between the operation amount of the aerosol valve and the opening of the valve varies depending on the aerosol valve, so only one of the valves opens first when opening slowly, It turned out that the biggest cause was that the operator stopped the operation there. Therefore, it is sufficient that the user does not stop the operation until both aerosol valves are opened.
  In the apparatus of the present invention, as means for balancing, means for hesitating to operate the operation means at a stretch is provided, so that the person who operates does not stop the operation on the way. Therefore, it is possible to prevent only one of them from being opened first in the middle of the operation, and it is possible to balance the discharge amounts of the first stock solution and the second stock solution. As a result, the problem of increasing the amount of ejection by only one stock solution was avoided, and a multi-discharge aerosol device that could be operated with one hand was put into practical use.
  In addition, as the above-mentioned trapping means, when the operating force is applied, the amount of operation is increased proportionally with the increase of the operating force at first, and the operating amount does not increase much even if the operating force is increased from the middle. Since means for nonlinearly changing so as to increase the operation amount again is adopted, the operating force becomes considerably large before the valves are opened, and both valves can be opened at once with a large force. Therefore, it is avoided that only one valve opens first.
[0009]
  When the passages communicating with the respective aerosol valves have respective open ends, the discharged first stock solution and second stock solution are received by an object such as a comb or other container, and on the object or in the container. Can be mixed in. On the other hand, when connecting as a common passage from the middle of the passage and providing a common jet outlet at the tip of the common passage, the two liquids are naturally mixed in the common passage. Moreover, even if not sufficiently mixed, since it is in a mixed state, mixing work after ejection is facilitated.

So that the balance between the twoMore certaintyCan be secured.

[0017]
  The apparatus A of FIG. 1 includes first and second aerosol apparatuses A1 and A2 each having a container body 1 and an aerosol valve 2, a connecting member 3 that connects the vicinity of the upper ends thereof, and both aerosol valves 2 And an operation mechanism 4 for simultaneously operating the.Further, the device A is provided with means for hesitating to operate the operation means at once as a means for balancing the injection amount. The dredging means will be described later.The operation mechanism 4 includes a push button 6 fitted to the stem 5 of each of the aerosol valves 2 and 2, an operation member 7 also serving as a cover for pushing the push button 6. The container body 1 of each aerosol device is a conventionally known bottomed cylindrical metal pressure resistant container, and has a cylindrical body portion 8 and a bottom portion 9 that closes the lower end thereof.
[0018]
  As shown in FIG. 2, a neck portion 11 that is somewhat narrower is provided at the upper end of the body portion 8 via a tapered shoulder portion 10. A cup-shaped mounting cup 12 is inserted inside the neck portion 11, and a fitting member 13 made of a metal plate is put on the outside of the neck portion 11 and crimped from the outside. The aerosol valve 2 is attached to the mounting cup 12 and accommodated in the neck portion 11. The aerosol valve 2 used here is provided in, for example, a housing 14, the stem 5 accommodated in the housing so as to be movable up and down, a spring 15 that constantly biases the stem 5 upward, and the stem 5. A valve rubber 17 for opening and closing the small hole 16 is provided. In the embodiment of FIG. 2, the valve rubber 17 is sandwiched between the upper end of the housing 14 and the mounting cup 12. However, the mounting cup 12 and the housing 14 are integrated, and the valve rubber of the mounting cup 12 and the fitting member 13 is integrated. A conventionally known one that sandwiches 17 can also be used. Further, an inner bag made of synthetic resin for protecting the inner wall may be accommodated inside the container body 1 and crimped to the container body 1 together with the mounting cup 12.
[0019]
  The container main body 1 of each of the first aerosol device A1 and the second aerosol device A2 is filled with, for example, a first liquid and a second liquid that are oxidative hair dyes, and is mixed immediately before being applied to the hair. These two liquids are separately filled in the container body of the first aerosol device and the container body of the second aerosol device so as to develop color. As the first liquid, for example, a mixture containing an oxidation dye, an alkali agent, a surfactant, or the like is used, and as the second liquid, a liquid containing an oxidant for oxidizing the oxidation dye can be used. Moreover, the above-mentioned two-component mixed urethane foam resin can be filled. These stock solutions are filled together with conventionally known propellants such as liquefied gas and compressed gas.
[0020]
  As shown in FIG. 3, the connecting member 3 can be made of a synthetic resin plate or the like having a notch hole 20 that fits into the lower end of the neck 11 of each container body 1, 1. In addition, the cap-shaped member which connects the bottom parts 5 of the container main body 1 can also be employ | adopted together. Furthermore, the band etc. which fasten the trunk | drum 4 of both the container main bodies 1 may be sufficient.
[0021]
  Returning to FIG. 1, cylindrical projections 21, 21 for ejection protrude from the side surfaces of the push buttons 6, 6 so as to face each other. The cylindrical protrusions 21 and 21 are respectively fitted and fixed to the left and right ends of the horizontal member 22 interposed between the push buttons 6 and 6, and the inner holes of the stems 5 and 5 are the horizontal members 22. Are communicated with each other by a communication passage 23 provided in the Further, a needle 24 extends upward from the central portion of the lateral member 22, and the lower end of the common passage 25 formed at the center of the needle 24 communicates with the central portion of the communication passage 23. Accordingly, the communication passage 23 and the common passage 25 are coupled in an inverted T shape.
[0022]
  As shown in FIG. 4, the upper end of the needle 24 is closed, and a shallow annular groove 26 is provided somewhat below the upper end. On the bottom surface of the annular groove 26,CommonA lateral hole 27 that communicates the passage 25 and the outside is formed. Further, a ring-shaped ring rubber 28 that closes the lateral hole 27 is normally put on the annular groove 26 so as to be in close contact therewith. A cap-shaped cap rubber may be used. Furthermore, in this embodiment, the operation member 7 serving as a cover, in which a cylindrical spout portion 30 having a spout 29 at the upper end and an operation step portion 31 for pressing the push buttons 6 and 6 are integrated, It covers the upper ends of the second aerosol devices A1, A2. The annular groove 26, the lateral hole 27, the ring rubber 28, and the operation step portion 31 constitute a spout opening / closing mechanism.
[0023]
  The inner surface of the spout part 30 is slidably fitted to the vicinity of the upper end of the needle 24. An engagement step 33 that engages with the upper end of the ring rubber 28 is provided on the inner surface of the upper end of the spout portion 30. The operation step portion 31 has a rectangular parallelepiped or elliptical column shape, and the spout portion 30 protrudes upward from the center portion of the upper surface thereof. As shown in FIG. 1, springs 32 and 32 are interposed between the push buttons 6 and 6 and the inner surface of the operation step portion 31, respectively.
[0024]
  Further, as shown in FIG. 1, an elliptical columnar skirt portion 34 is provided around the operation step portion 31 so as to cover the upper portions of both the aerosol devices A1 and A2. The skirt portion 34 can slide up and down with respect to the mounting cup 12. However, when the operation portion 21 is separated from the skirt portion 34, or the flat portion 35 between them is configured to be freely deformable, the skirt portion 34 is fitted and fixed to the mounting cup 12 or the neck portion from the outside. be able to. In this case, since the skirt portion 34 also serves as a connecting member, the independent connecting member 3 as shown in FIG. 2 is not necessary.
[0025]
  In the multi-discharge aerosol device A configured as described above, when the operating member 7 is pushed downward, first, the push buttons 6 and 6 and the stems of the aerosol devices A1 and A2 are attached to the springs 15 of the aerosol valves 2 and 2, respectively. Depressed against power. Thereby, the contents of the container body 1 are ejected from the cylindrical projection 21 into the communication passage 23. However, at that time, since the spout part 30 has not yet lowered relative to the needle 24, the lateral hole 27 of the spout part 30 is blocked by the ring rubber 28. Therefore, the contents ejected from both container bodies 1 are sufficiently mixed in the communication passage 23 and the common passage 25.
[0026]
  When the operating member 7 is further pushed down to increase the biasing force of the spring 15 of the aerosol valve 2 or when the spring 15 or the stem 5 bottoms out, the needle 24 does not descend any further. Therefore, the springs 32, 32 between the operation step portion 31 and the push buttons 6, 6 start to shrink, the spout portion 30 descends with respect to the needle 24, and the engagement protrusion 33 of the spout portion 30 elastically deforms the ring rubber 28. Thus, the lateral hole 27 is opened. Thereby, the above mixture is ejected from the ejection port 29 to the outside.
[0027]
  as mentioned aboveThis device AThen, until the operation amount of the operation member 7 exceeds a predetermined level, that is, until both the aerosol valves 2 and 2 are sufficiently opened, the spout portion 30 is prevented from being ejected to the outside by the opening / closing mechanism. Therefore, it is possible to prevent waste that only one stock solution is ejected first.
[0028]
  FIG. 5 shows a multi-discharge aerosol apparatus B having a pistol type operation mechanism 4. In this case, a fixing cap 35 that also serves as a connecting member is fitted and fixed to the container main bodies 1 and 1, a needle 36 is projected from the upper side surface of the fixing cap 35, and a spout 37 is slidably fitted to the shaft rod. ing. The needle 36 and the spout 37 are substantially the same as the needle 24 and the spout part 30 of FIG. However, some play 38 is provided between the engagement step portion 33 of the spout 37 and the ring rubber 28 placed around the needle 24. Further, a trigger 39 extending downward is provided at the rear end of the spout 37. The needle 36 is provided with a common passage 40 through which the mixed liquid passes. The common passage 40 reaches the inside of the top plate 41 of the fixed cap 35 and opens to the inner surface side at the center of the top plate 41.
[0029]
  Furthermore thisDevice BThen, the lower end of the rotation link 42 is rotatably connected to the transverse member 22 attached to the push buttons 6 and 6 of both aerosol apparatuses A1 and A2. On the other hand, a slide link 43 extends rearward from the trigger 39, and a rear end of the slide link 43 is rotatably connected to an upper end of the rotary link 42. A pair of L-shaped passages 44 communicating with the push buttons 6, 6 are formed in the transverse member 22, and these passages 44 are opened on the upper surface of the transverse member 22. These passages 44 and the common passage 40 at the center of the top plate of the fixed cap are connected by flexible tubes 45 and 45 so as not to prevent the horizontal member 22 from moving up and down.
[0030]
  In the multi-discharge aerosol device B configured as described above, when the upper part of the container bodies 1 and 1 is gripped and the trigger 39 is pulled, the sliding link 43 is pushed backward, and the rotation link 42 rotates clockwise. As a result, the transverse member 22 is lowered. Thereby, the aerosol valve in the container body 1 is opened. At that time, since there is some play 38 between the engaging step 33 of the spout 37 and the ring rubber 28, the lateral hole of the spout 37 is not immediately opened. Therefore, the two liquids discharged from both the aerosol devices A1 and A2 are filled in the L-shaped passage 44, the tube 45 and the common passage 40, and mixed or mixed in the common passage 40. Next, when the trigger 39 is further pulled, the lateral hole of the spout 37 is opened, and the mixed contents are discharged to the outside. As described above, also in the multiple discharge aerosol device B of FIG. 5, the ejection to the outside is suppressed until the operation amount of the spout 37 as the operation member exceeds a predetermined level, that is, until both the aerosol valves are sufficiently opened. The Therefore, the waste that only one undiluted solution is ejected first is prevented.
[0031]
  When the trigger 39 is released after the two liquids are ejected, the lateral member 22 is raised by the biasing force of the spring of the aerosol valve. Thereby, the rotation link 42 is rotated counterclockwise, and the sliding link 43 is pushed to the tip side. Therefore, it returns to the initial state. When the rotation link 42 is straightened in the vertical direction or further rotated in the clockwise direction, the rotation link 42 becomes locked, and the rotation link 42 cannot be rotated counterclockwise by the rising of the lateral member 22. Therefore, when the rotation link 42 is rotated to such an angle, the return spring 46 is interposed between the rear end of the spout 37 and the fixed cap 41, and the spout 37 is returned by its urging force.
[0032]
  The multi-discharge aerosol device C in FIG.Outside the scope of the present inventionThe first passage 51 and the second passage 52 connected to the stems of the aerosol devices A1 and A2 are connected together in the vicinity of the opening end 53. A pilot-type first valve 55a and a second valve 55b are interposed on the aerosol valve side of the branch portion 54 of each passage. Further, first and second pilot circuits 56a and 56b are led out from between the valves 55a and 55b and the stem 5 of the aerosol valve, and are connected to the pilot ports 57b and 57a of the counterpart valve. The open end 53 is provided with a spout that is always open. Although not shown, thisDevice CIn this case, operation members such as a push button and a lever for simultaneously operating both aerosol valves are provided.
[0033]
  thisDevice CThen, for example, when both pushbuttons are pushed down to open both aerosol valves, the stock solution and the like are filled between the valves 55a and 55b and the stem 5 in the respective passages 51 and 52, and the pressure in that region rises. Therefore, the pilot ports 57b and 57a on the other side are energized, and the respective passages 51 and 52 are opened. Therefore, the undiluted | stock solution and propellant of each container main body 1 are ejected in the state mixed in the opening end 53. FIG.
[0034]
  At this time, if the push button is not pressed sufficiently, only one of the aerosol valves of the first aerosol device A1 is opened and the aerosol valve of the second aerosol device A2 is not yet opened. The undiluted solution and propellant are filled between the aerosol valve and the first valve 55a. This opens the second valve 55b on the second aerosol device side. However, since the aerosol valve on the second aerosol device side is not sufficiently opened, the stock solution and the propellant are not ejected. Therefore, the pressure of the second passage 52 on the second aerosol device side and the second pilot circuit 56b communicating with the second passage 52 do not increase. Therefore, the first passage 51 on the first aerosol device side remains closed. Therefore, both stock solutions do not erupt eventually.
[0035]
  When the push button is further pressed and the aerosol valve of the second aerosol device A2 is opened, the pressure of the second pilot circuit 56b rises for the first time, and the first valve 55a of the first aerosol device A1 is opened. Therefore, the stock solution of the second aerosol device A2 and the like are ejected through the first valve 55a at the same time as the stock solution of the second aerosol device A2 is ejected through the previously opened second valve 55b on the second aerosol device A2 side. To do. As a result, both stock solutions and the like are ejected to the outside while being mixed on the downstream side of the branching portion 54.
[0036]
  In this way, in the apparatus C of FIG. 6, the action of the pair of pilot-type valves 55a and 55b that restrain each other prevents the situation where only one of the undiluted liquids is ejected, and the two liquids are reliably ejected. .
[0037]
  thisDevice CThen, a pilot valve is provided in each stock solution passage, and an opening / closing mechanism is not provided in the common passage after the branching portion 54. For this reason, the common passage can be omitted, and a spout can be separately provided at the discharge port of each pilot valve so that the two stock solutions can be mixed after being discharged to the outside. On the other hand, in order to protect the inside of the spout, an opening / closing mechanism that opens in cooperation with the operation of the push button may be provided at the open end of each passage or common passage as desired. In addition, a relief valve that opens by an internal pressure can be provided at the opening end.
[0038]
  The apparatus D of FIG. 7 ejects the stock solutions of the three aerosol apparatuses A1, A2, and A3 in a mixed state. In this device, one end of a passage 61 is connected to the stem 5 of the aerosol valve of each aerosol device, and a common passage 62 is formed at the tip side, and a normal aerosol valve 63 is attached to the tip of the common passage 62. It is connected as an opening / closing mechanism. Although not shown, a common push button for operating the three stems 5 at the same time is provided, and after the common push button is pressed, a sequential operation mechanism is provided to open the spout aerosol valve 63. Yes. Reference numeral 65 denotes a check valve for preventing the stock solution or the like from flowing back into the container body.
[0039]
  As the sequential operation mechanism, for example, a mechanism that opens the aerosol valve first by providing a difference in spring strength as shown in FIG. 1 can be adopted. AlsoOutside the scope of the present invention,It can also be realized by a pilot type valve similar to FIG. However, in FIG.Device DIn this case, since there are three aerosol devices, a pilot type valve is provided in each passage, and the pilot type valve is not provided until the pilot pressure from the other two aerosol valves exceeds the predetermined pressure. To open. For example, the pilot pressures of the other two aerosol valves are connected by an AND circuit and then connected to a pilot type valve.
[0040]
  aboveApparatus ADIn either case, an opening / closing mechanism is actually provided on the way from the aerosol valve to the spout, but only one undiluted solution is ejected by providing a means to hesitate to operate the operating member at once. You can avoid the situation.The apparatus of the present invention is characterized by providing this means.As such a wrinkle means, for example, the change in the operation amount with respect to the pressing force of the operation member is made non-linear as shown in FIG.
[0041]
  In the graph of FIG. 8, the horizontal axis indicates the operation force F, and the vertical axis indicates the operation amount L. In this graph, at the initial stage R1 of the operation, the operation amount L increases proportionally as the operating force F is increased. When the operation amount reaches a certain level L0, even if the operation force is increased, the operation amount hardly increases, and the level R2 is maintained. Next, when the operating force F is further increased to exceed a predetermined level F0, the operation amount L increases at a stroke (step R3). Thereafter, the phase R4 is increased again proportionally.
[0042]
  After the relationship between the operation force and the operation amount is determined as described above, the opening timing of the aerosol valves of the first and second aerosol devices is increased to the positions indicated by the symbols T1 and T2 in FIG. Set to stage R3. Then, even when the operation member is slowly pushed down, the user gradually increases the operation force at the stage R1 where the injection does not start, and operates strongly at the stage R2 where the operation amount does not increase. When the operating force exceeds the predetermined level F0, the operation amount suddenly increases from there, so that the two aerosol valves are naturally pushed down simultaneously. Therefore, the situation where only one of the aerosol valves is opened first is avoided.
[0043]
  The relationship between the operation force F and the operation amount L is that a common operation member that pushes down the push buttons of both aerosol valves is a link mechanism such as a toggle link or a cam such as a plate cam whose operating radius varies depending on the angle. This can be realized by operating the mechanism with an operation lever or the like via a mechanism or a transmission mechanism similar to the mechanism. That is, generally, the biasing force and the deflection amount of the spring of the aerosol valve are linearly deformed, so that the relationship between the input side and the output side of the transmission mechanism is made constant in the first stage R1, and doubled in the next stage R2. By applying a force action or providing an additional load, only the operating force is increased. In step R3 where the manipulated variable suddenly increases, a speed increasing action is applied. Thereby, a relative relationship approximate to the graph of FIG. 8 can be obtained.
[0044]
  In the middle of the stroke of the operating member, a resistance means such as a protrusion that cannot be overcome unless a predetermined operating force is applied may be provided. Strictly speaking, in this case, the corresponding relationship is different from the graph of FIG. 8, but when there is not much difference in the valve opening starting force, both the aerosol valves are opened at once when the resistance means is overcome. Can do. Therefore, substantially the same effect can be achieved.
[0045]
  Means or resistance means for making the operating force and operation amount non-linearAgainst1 through 6 spout opening and closing mechanismTheIt can also be employed together. In that caseIs openSince the opening side of the spout does not open until the aerosol valve is sufficiently opened by the closing mechanism, the non-linear means and the resistance means serve to improve the usability of the aerosol apparatus to the user. That is, in FIG.Device AIn other words, since the operation force of the operation member 7 changes in two stages, it is difficult to understand how much the operation member 7 should be pushed down. Therefore, try not to feel the feeling of opening the aerosol valve as much as possible, and emphasize the feeling of opening the spout. This makes it easier for the user to grasp the feeling of opening the spout by depressing the operating member and the level of operating force that maintains that state.
