Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multiple discharge aerosol device. More specifically, the present invention relates to a multiple-ejection aerosol apparatus that separates and stores two or more types of undiluted solutions, ejects them simultaneously, and uses them while mixing.

[0002]

2. Description of the Related Art Conventionally, a first liquid containing a polyol and a second liquid containing an isocyanate are filled in separate aerosol devices, and conduits connected to the outlets of the aerosol valves of the respective aerosol devices are connected to a common mixing pipe. A two-pack type urethane foam manufacturing apparatus has been proposed (Japanese Patent Laid-Open No. 58-168).
No. 32). When the valves are opened by pressing the push buttons of the respective aerosol devices, the two are combined in a common passage, and are ejected from the ejection port in a mixed or mixed state.

[0003]

In the above-mentioned conventional two-pack type evaporator, it is necessary to hold each eazole device in left and right hands and operate each push button. For this reason, both hands are closed, and it is extremely inconvenient to discharge a two-component hair dye to a comb or the like. In addition, since the operation amounts of both push buttons can be adjusted, it is possible to finely adjust the mixing ratio of the first liquid and the second liquid. If only the first liquid is pressed strongly, only the first liquid or the second liquid is ejected, which is wasted. An object of the present invention is to provide a multiple-discharge aerosol apparatus that can be operated with one hand and can simultaneously eject two liquids without using much care.

[0004]

According to the present invention, there is provided a multi-discharge eazor device comprising a pressure-resistant container body, a first undiluted solution and a propellant housed in the container body, and a normally-closed side provided with a return spring attached to the container body. A first aerosol valve biased to the first aerosol valve, a first aerosol device provided with a passage leading from the outlet of the first aerosol valve to the ejection port, a pressure-resistant container body, and a first container accommodated in the container body. (2) a stock solution and a propellant, a second aerosol valve attached to the container body, which is normally urged to a closed side by a return spring, and a passage leading from the outlet of the second aerosol valve to the jet port. A second aerosol device, a single operating means for simultaneously operating the first aerosol valve and the second aerosol valve, and a discharge amount from the first aerosol valve It is characterized in that it comprises a means for balancing the discharge amount from the second Eya tetrazole valve.

In such a multiple discharge aerosol device, the passage of the first aerosol device and the passage of the second aerosol device are connected to a common passage from the middle thereof, and the first undiluted solution and the second undiluted solution are connected to the end of the common passage. A common ejection port for ejecting the undiluted solution together may be provided.

As the means for balancing, it is possible to employ an opening / closing mechanism in which the passage or the ejection port is always closed and opened only when the operation amount of the operation means reaches a predetermined level. Alternatively, as a means for balancing, an opening / closing mechanism that opens only when the pressure on the aerosol valve side reaches a predetermined level while the passage or the ejection port is always closed may be adopted. The balancing means includes a pilot-type valve provided in the middle of a passage communicating with each of the aerosol valves, and a counterpart when the pressure at the outlet of one of the aerosol valves reaches a predetermined pressure. And a pilot circuit for opening the pilot type valve. It is preferable that the apparatus having the above-mentioned balancing means be provided with a means for allowing the operator to sense when the passage or the spout is opened by a change in the operating force.

[0007] Further, the above-mentioned balancing means provides the operator with an operation force of the operation means that passes through a range of a small operation force that causes a difference in the opening degree of each aerosol valve, and an appropriate valve opening amount. It can be used as a means of encouraging the user to reach a strong operation level at a stretch. In this case, as a means for encouraging, when applying the operation force, the operation amount is initially increased proportionally with the increase in the operation force, and even if the operation force is increased halfway, the operation amount does not increase so much. Then, it is possible to use a means for nonlinearly changing the operation amount again. Also, as a means of encouragement, an operation resistance commensurate with the repulsion force of the return spring of the aerosol valve should be given before the aerosol valve starts to open, so that the operator does not sense the opening of the aerosol valve. You can also.

[0008]

According to the device of the present invention, when the operating means is operated, the first aerosol device provided with the first aerosol device is operated.
The valve and the second valve provided in the second eazole device are simultaneously opened, and the two liquids can be ejected. That is, in the apparatus of the present invention, since there is a single operation means, it is easy to receive the ejected matter with a comb or the like while operating the operation means with one hand. In addition, when the first valve and the second valve are operated by a single operating means, depending on the operation state, only the ejection amount of one of the undiluted solutions may increase. In the apparatus of the present invention, such a problem is avoided by providing a means for balancing the ejection amount, and a multiple-ejection aerosol apparatus that can be operated with one hand has been put to practical use.

When the passages communicating with the respective aerosol valves have respective open ends, the discharged first undiluted solution and the second undiluted solution are received by an object such as a comb or another container, and are discharged from the object. Or in a container. On the other hand, when the two passages are combined as a common passage from the middle of the passage and a common ejection port is provided at the end of the common passage, the two liquids are naturally mixed in the common passage. Even if they are not sufficiently mixed, since they are in a mixed state, the mixing operation after the ejection is facilitated.

There are various possible reasons why the balance between the discharge amount from the first valve and the discharge amount from the second valve is lost and only the discharge amount from one side increases. According to the study of the present inventor, the relationship between the operation amount of the aerosol valve and the opening degree of the valve has variation due to 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 operating there. Therefore, it is sufficient that the user does not stop the operation until both the aerosol valves are opened. As a means for balancing, if a passage or ejection port is always closed and an opening / closing mechanism that opens the ejection port for the first time when the operation amount of the operating means reaches a predetermined level is adopted, only one of the aerosol valves is used for the scale. Even if opened first, the undiluted solution does not squirt. Therefore, the user continues to operate the operation means. Then, when the manipulated variable exceeds a predetermined level and the other aerosol valve is opened, the passage or the ejection port is opened for the first time, and both stock solutions are discharged together. Thereby, a balance between the two can be ensured.

When an opening / closing mechanism which is opened by the pressure of the azole valve is employed as a means for balancing, none of the stock solutions is injected until both valves are sufficiently opened and the pressure in the passage exceeds a predetermined level. Then, when both predetermined levels are exceeded, both stock solutions are ejected together. As a result, it is possible to avoid a situation in which only one undiluted solution is jetted.

In the case where the above-mentioned pilot-type valve and a pilot circuit for opening the other pilot-type valve are used as a means for balancing, if the discharge pressure of one of the valves does not increase to a predetermined pressure, the other valve is used. Pilot type valve on valve side does not open. Only when the pressures at the outlets of both aerosol valves exceed a predetermined level do both pilot valves open and the first
The stock solution and the second stock solution squirt together.

[0013] In a multi-discharge aerosol apparatus provided with means for allowing the operator to sense when the spout is opened by a change in the operating force, the operator can easily maintain the level of the operating force, and during the ejection, A situation in which only one undiluted solution spouts can be avoided.

When a means for encouraging the operating means to be operated at once is provided as a means for balancing, it is possible to prevent only one of them from being opened first during the operation, and to discharge the first undiluted solution and the second undiluted solution. The amount can be balanced.

As an encouraging means, when the operating force is applied, the operating amount is initially increased in proportion to the increase of the operating force. In the case where a means for changing the operation amount in a non-linear manner is employed again so that the operation amount increases again, the operation force becomes considerably large before the valve opens, and both valves can be opened at a stretch with a large force. Therefore, it is avoided that only one of the valves opens first. In addition, as a means of encouraging, before the opening of the aerosol valve, an operation resistance corresponding to the repulsive force of the return spring of the aerosol valve is given,
Accordingly, in the case where a valve that prevents the operator from starting to open the azole valve is employed, the valve is not opened even if the user slightly operates the valve, so that the operator strongly operates the valve. Therefore, both valves are opened greatly at once.

The container body 1 of each aerosol device is a conventionally known bottomed cylindrical metal pressure-resistant container, and has a cylindrical body 8 and a bottom 9 closing the lower end thereof.

As shown in FIG. 2, an upper end of the body portion 8 is provided with a neck portion 11 which is slightly thinner via a tapered shoulder portion 10. A cup-shaped mounting cup 12 is inserted into the neck 11, and a fitting member 13 made of a metal plate is put on the outside of the neck 11 and crimped from the outside. The aerosol valve 2 is attached to a mounting cup 12 and housed in a neck 11. The aerosol valve 2 used here is provided in, for example, a housing 14, the stem 5 housed in the housing so as to be vertically movable, a spring 15 for constantly urging the stem 5 upward, and the stem 5. A valve rubber 17 for opening and closing the small hole 16 is provided.
Although the valve rubber 17 is interposed between the upper end of the housing 14 and the mounting cup 12 in the embodiment of FIG.
4 can be used as well, and a conventionally known one that sandwiches the valve rubber 17 of the mounting cup 12 and the fitting member 13 can be used. Also, an inner bag made of a synthetic resin for protecting the inner wall is accommodated inside the container body 1, and the mounting cup 1 is provided.
The container body 1 may be crimped together with the container body 2.

In each of the container bodies 1 of the first and second aerosol devices A1 and A2, for example, a first liquid and a second liquid serving as an oxidative hair dye are filled.
The two liquids are separately filled into the container body of the first aerosol device and the container body of the second aerosol device so as to mix and develop color immediately before application to the hair. First
As the liquid, for example, a mixture containing an oxidation dye, an alkali agent, a surfactant, and the like is used. As the second liquid, a liquid containing an oxidizing agent for oxidizing the oxidation dye is used. Further, 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.

As shown in FIG. 3, the connecting member 3 has a cut-out hole 2 fitted to the lower end of the neck 11 of each container body 1, 1.
It can be composed of a plate made of a synthetic resin provided with 0. In addition, the cap-shaped member which connects the bottom parts 5 of the container main body 1 can also be employ | adopted together. Further, a band or the like for fastening the body portions 4 of both the container bodies 1 may be used.

Returning to FIG. 1, the side surfaces of the push buttons 6 and 6 have cylindrical projections 21 for discharge facing each other.
21 protrudes. The cylindrical projections 21, 21 are
The right and left ends of the horizontal member 22 interposed between the two push buttons 6, 6 are fitted and fixed respectively, and the inner holes of the stems 5, 5 communicate with each other by a communication passage 23 provided in the horizontal member 22. ing. Further, a needle 24 extends upward from the center of the horizontal member 22, and the lower end of a common passage 25 formed at the center of the needle 24 is connected to the communication passage 2.
3 communicates with the center. Thereby, the communication passage 23
And the common passage 25 are connected in an inverted T-shape.

As shown in FIG. 4, the upper end of the needle 24 is closed, and a little below the upper end, a shallow annular groove 2 is formed.
6 are provided. A lateral hole 27 is formed in the bottom surface of the annular groove 26 to communicate the communication passage 25 with the outside. Further, the annular groove 26 is covered with a ring-shaped rubber 28 which normally closes the horizontal hole 27 so as to be in close contact with the annular groove 26. Note that a cap-shaped cap rubber may be used.
Further, in the present embodiment, the operating member 7 serving also as a cover, in which the cylindrical spout portion 30 having the ejection port 29 at the upper end and the operating step portion 31 for pressing the push buttons 6, 6 are integrated,
It is put on the upper end of the first and 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.

The inner surface of the spout portion 30 is slidably fitted near the upper end of the needle 24. Spout part 3
An engagement step portion 33 that engages with the upper end of the ring rubber 28 is provided on the inner surface of the upper end of the ring rubber 28. The operation step portion 31 has a rectangular parallelepiped or elliptical column shape, and the spout portion 30 protrudes upward from the center of the upper surface thereof.
Also, as shown in FIG.
The springs 32, 32 are interposed between the inner surfaces of the springs 1 and 1, respectively.

As shown in FIG. 1, an elliptical column-shaped 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 is slidable up and down with respect to the mounting cup 12. However, in the case where the operating portion 21 is separated from the skirt portion 34 or the flat portion 35 between the two is configured to be flexibly 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, an independent connecting member 3 as shown in FIG. 2 is not required.

When the operating member 7 is depressed downward, the multi-discharge aerosol apparatus A constructed as described above first presses the push buttons 6 of the respective aerosol apparatuses A1, A2.
The stem 6 and the stem are pushed down against the urging force of the spring 15 of the aerosol valves 2, 2. Thereby, the contents of the container body 1 are ejected from the cylindrical projection 21 into the communication passage 23. However, at this time, since the spout portion 30 has not yet been lowered relative to the needle 24, the lateral hole 27 of the spout portion 30 is closed 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.

When the operating member 7 is further depressed to increase the urging force of the spring 15 of the aerosol valve 2 or when the spring 15 or the stem 5 strikes the bottom, the needle 24 does not descend any further. Therefore, springs 32, 32 between the operation step portion 31 and the push buttons 6, 6 start to contract, the spout portion 30 descends with respect to the needle 24, and the engagement protrusion 33 of the spout portion 30 moves to the ring rubber 28.
Is elastically deformed to open the lateral hole 27. As a result, the above mixture is ejected from the ejection port 29 to the outside.

As described above, in the present embodiment, the operating member 7
Until the operation amount 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 spouted to the outside by the opening and closing mechanism. Therefore, waste such that only one of the undiluted liquids is ejected first is prevented.

FIG. 5 shows a multiple-discharge evaporator B having a pistol-type operating mechanism 4. In this apparatus, a fixing cap 35 also serving as a connecting member is fitted and fixed to the container bodies 1 and 1, a needle 36 is projected from an upper side surface of the fixing cap 35, and a spout 37 is slidably fitted to the shaft. ing. The needle 36 and the spout 37 are substantially the same as the needle 24 and the spout portion 30 in FIG. However, some play 38 is provided between the engagement step 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 is provided on the top plate 4 of the fixed cap 35.
1 and open to the inner surface side at the center of the top plate 41.

Further, in this embodiment, the lower end of the rotating link 42 is rotatably connected to the horizontal member 22 attached to the push buttons 6, 6 of both the aerosol devices A1, A2. On the other hand, backward from the trigger 39, the sliding link 43
The rear end of the sliding link 43 is rotatably connected to the upper end of the rotating link 42. The lateral member 22 has a pair of L-shaped passages 4 communicating with the respective push buttons 6, 6.
4 are formed, and the passages 44 are open on the upper surface of the cross member 22. The passages 44 and the common passage 40 in the center of the top plate of the fixed cap are respectively provided with flexible tubes 45 and
It is connected at 45.

The multi-discharge aerosol apparatus B constructed as described above holds the upper parts of the container bodies 1 and 1 and the trigger 3
When the user pulls 9, the sliding link 43 is pushed rearward, and the rotating link 42 rotates clockwise, and the horizontal member 22 is lowered by the action. Thereby, the aerosol valve in the container body 1 is opened. At this time, there is some play 38 between the engagement step 33 of the spout 37 and the ring rubber 28, so that the lateral hole of the spout 37 is not immediately opened. Therefore, the two liquids discharged from both the aerosol devices A1 and A2 fill the L-shaped passage 44, the tube 45 and the common passage 40, and are mixed or mixed in the common passage 40. Then, when the trigger 39 is further pulled, the lateral hole of the spout 37 is opened, and the mixed content is discharged to the outside. As described above, in the multiple discharge aerosol apparatus B of FIG. 5 as well, 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. You. Therefore, waste such that only one undiluted solution is ejected first is prevented.

When the trigger 39 is released after ejecting the two liquids, the horizontal member 22 is raised by the urging force of the spring of the aerosol valve. As a result, the rotating link 42 rotates counterclockwise, and pushes the sliding link 43 toward the distal end. Therefore, it returns to the initial state. When the rotating link 42 is straightened in the vertical direction or further rotated clockwise, the locked state is established, and the rotating link 42 is
Cannot be rotated counterclockwise. Therefore, when rotating the rotation link 42 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 the urging force.

In the multiple discharge aerosol device C shown in FIG. 6, the first passage 51 and the second passage 52 connected to the stems of the aerosol devices A1 and A2 are connected together near the open end 53. Then, a pilot type first valve 55 is provided to the aerosol valve side from the branch portion 54 of each passage.
a and the second valve 55b. Further, first and second pilot circuits 56a, 56b are led out from between the valves 55a, 55b and the stem 5 of the azole valve, and pilot ports 57b, 5b,
7a. A spout or the like which is always open is provided at the opening end 53. Although not shown, also in this embodiment, operating members such as push buttons and levers for simultaneously operating both the aerosol valves are provided.

In this embodiment, when, for example, the push button is depressed to open both the aerosol valves, the undiluted solution or the like fills between the valves 55a, 55b and the stem 5 in the respective passages 51, 52, and the pressure in that region is increased. Rises. Therefore, the pilot ports 57b and 57a of the other party
And the respective passages 51 and 52 are opened. Therefore, the undiluted solution and the propellant of each container body 1 are ejected in a mixed state at the opening end 53.

At this time, the pressing method of the push button is insufficient,
If only one of them, for example, only the aerosol valve of the first aerosol device A1 opens and the aerosol valve of the second aerosol device A2 does not open yet, the undiluted solution and the propellant on the first aerosol valve side will be the same as the aerosol valve and the propellant. It is filled between one valve 55a. Thereby, the second valve 55b on the side of the second aerosol device is opened. However, since the aerosol valve on the second aerosol device side is not sufficiently opened, the undiluted solution and the propellant do not squirt. Therefore, the pressure of the second passage 52 on the side of the second azole device and the pressure of the second pilot circuit 56b communicating therewith do not increase.
For this reason, the first passage 51 on the first aerosol device side remains closed. Therefore, neither of the stock solutions ends up squirting.

When the push button is further pressed and the azole valve of the second azole device A2 is opened, the pressure of the second pilot circuit 56b first rises, and the first valve 55a of the first azole device A1 is opened. Therefore, the undiluted solution and the like of the second aerosol device A2 are ejected through the second valve 55b of the second aerosol device A2 which has been opened in advance, and the undiluted solution and the like of the first aerosol device A1 are also ejected through the first valve 55a. I do. As a result, both undiluted solutions and the like are ejected to the outside while being mixed on the downstream side of the branch portion 54.

As described above, in the device C shown in FIG. 6, a pair of pilot-type valves 55a, 55
By the action of b, the situation where only one of the undiluted liquids is ejected is avoided, and the two liquids are surely ejected in a mixed state.

In this embodiment, a pilot valve is provided in each stock solution passage, and no opening / closing mechanism is provided in the common passage after the branch portion 54. Therefore, the common passage may be omitted, and spouts may be separately provided at the discharge ports of the respective pilot valves so that the two undiluted solutions can be mixed after being discharged 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 opening end of each passage or the common passage, if desired. Further, a relief valve or the like that opens by internal pressure can be provided at the open end.

The device D of FIG.
The stock solution of 1, A2 and A3 is ejected in a mixed state. In this apparatus, 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 on the distal end side, and a normal aerosol valve 63 is connected to the distal end of the common passage 62 by a spout. It is connected as an opening and closing mechanism. Although not shown, three stems 5
Are provided at the same time, and after the common push button is depressed, a sequential operation mechanism for opening the spout aerosol valve 63 is provided. Reference numeral 65 denotes a check valve for preventing the undiluted solution or the like from flowing back into the container body.

As the above-mentioned sequential operation mechanism, for example, as shown in FIG. 1, a mechanism in which an aerosol valve opens first by providing a difference in spring strength can be employed.
It can also be realized by a pilot-type valve similar to FIG. However, in the case of the embodiment of FIG. 7, since there are three aerosol devices, a pilot-type valve is provided in each passage, and when both pilot pressures from the other two aerosol valves exceed a predetermined pressure. For the first time, open the pilot type valve. 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.

In each of the above embodiments, the opening / closing mechanism is actually provided on the way from the aerosol valve to the spout. However, it is also possible to provide means for encouraging the operator to operate the operating member at once. Thus, it is possible to avoid a situation in which only one of the undiluted liquids is spouted. As a means for such encouragement, for example, a change in the operation amount with respect to the pressing force of the operation member is made non-linear as shown in FIG.

In the graph of FIG. 8, the horizontal axis represents the operation force F, and the vertical axis represents the operation amount L. In this graph, in the initial stage R1 of the operation, the operation amount L increases proportionally as the operation force F increases. When the operation amount reaches a certain level L0, the operation amount hardly increases even if the operating force is increased, and the level R is maintained at that level.
It becomes 2. Next, when the operating force F is further increased to exceed a predetermined level F0, the operation amount L increases at a stretch (step R3). After that, the process reaches the stage R4 which increases again proportionally.

After the relationship between the operation force and the operation amount is determined as described above, the timing at which the aerosol valves of the first and second aerosol devices are opened is set to the positions indicated by reference numerals T1 and T2 in FIG. It is set to the step R3 which increases at a stretch. Then, even when the operation member is slowly pushed down, the user gradually increases the operating force in the stage R1 where the injection does not start, and performs the operation strongly in the stage R2 where the operation amount does not increase. The operating force is at a predetermined level F0
Is exceeded, the manipulated variable suddenly increases from that point, and naturally the two aerosol valves are simultaneously depressed. Therefore, a situation in which only one of the azole valves is opened first can be avoided.

The relationship between the operation force F and the operation amount L is such that a common operation member for depressing the push buttons of both the aerosol valves includes a link mechanism such as a toggle link,
This can be realized by a structure in which the operating radius is changed by an angle using a cam mechanism such as a plate cam, or an operation lever or the like via a transmission mechanism similar to them. That is, in general, the biasing force and the amount of deflection of the spring of the aerosol valve are linearly deformed. Therefore, in the first stage R1, the relationship between the input side and the output side of the transmission mechanism is kept constant, and in the next stage R2, the relationship is doubled. By exerting a force effect or providing an additional load, only the operating force is increased. Then, at a stage R3 in which the operation amount suddenly increases, the speed increasing action is applied. FIG. 8
Can be obtained.

In the middle of the stroke of the operating member, a resistance means such as a projection which cannot be overcome without applying a predetermined operating force may be provided. In that case, the correspondence is strictly different from the graph of FIG. 7. However, if there is not much difference in the valve opening start force, when overcoming the resistance means, it is necessary to open both the aerosol valves at once with the momentum. Can be. Therefore, substantially the same operation and effect can be achieved.

The above-mentioned means for making the operating force and the operation amount non-linear or the resistance means can be employed together with the spout opening / closing mechanism shown in FIGS. In that case, since the opening side of the spout is not opened until the azole valve is fully opened by the opening / closing mechanism, the means for making the non-linearity and the resistance means rather serve to improve the user's feeling of using the azole system. That is, in the embodiment of FIG. 1, since the operating force of the operating member 7 changes in two stages, it is difficult to know how much the operating member 7 has to be pushed down. For this reason, the feeling of opening the aerosol valve is made as little as possible, and the operation feeling of opening the spout is emphasized. This makes it easier for the user to grasp the feeling of opening the spout by pressing down the operation member and the degree of operation force for maintaining the state.
