Description

  The present invention relates to an actuator for an aerosol container for transfer and filling. When used by transferring from an aerosol container having a large capacity to a small aerosol container that is convenient to carry, it is not necessary to remove the actuator and the transfer is automatically performed from injection. It can be switched to filling.

Aerosol products filled with a pressure-resistant aerosol container equipped with an aerosol valve filled with the content liquid and propellant can be easily ejected by operating the actuator such as a push button attached to the aerosol valve. For example, various contents are filled and used.
When such aerosol products are carried and used, many aerosol containers have large contents, and it has been necessary to carry more aerosol containers than necessary.
Therefore, a double-structured small-capacity aerosol container that can separate and fill the content liquid and the propellant is used immediately before use or when the contents are used up from an aerosol container with a large internal capacity. Various proposals have been made that can be refilled and used repeatedly.

For example, in the refill container and in-use filling system disclosed in Patent Document 1, a cylinder and a free piston are provided in an aerosol container body having an aerosol valve at the opening to form a double structure, and the content liquid is placed in the cylinder above the piston. Fill and fill the lower part of the piston and between the cylinder and the container body, and operate the push button attached to the stem of the aerosol valve to perform normal injection and take out only the liquid content On the other hand, when the content liquid is used up, remove the push button on the stem of the aerosol valve just before use, connect the adapter of the stock solution filling device, and put the content liquid into the cylinder above the piston at a pressure higher than the pressure of the propellant. I try to fill it.
Moreover, in the aerosol refilling apparatus of patent document 2, it is set as the double structure which provided the inner bag in the aerosol container, and isolate | separated the propellant and the content liquid, filled the content in the inner bag, The propellant was filled in between and the push button attached to the stem of the aerosol valve communicating with the inner bag was operated to perform normal injection and only the content liquid was taken out, while the content liquid was used up In some cases, the push button on the stem of the aerosol valve is removed just before use, the aerosol injection connection part of the refilling device is connected, and the content liquid is refilled into the inner bag using compressed air higher than the pressure of the propellant as the driving force. I am doing so.

Hereinafter, embodiments for carrying out the present invention will be described in detail.
The transfer container aerosol actuator 10 of the present invention is an actuator that is used by being attached to an aerosol container having a small capacity, which is used when carrying an aerosol product, and is an aerosol container having a large capacity. Is used as a parent container and attached to an aerosol container which is a child container when the content liquid is transferred and filled, for example, as a push button.

  The transfer-filling aerosol container (child can) C to which the transfer-filling aerosol container actuator 10 is attached is a double-structured aerosol container capable of separating and filling the content liquid and the propellant. A flexible inner bag is provided, and the inner bag is filled with the content liquid, while a propellant is filled between the inner bag and the aerosol container, and the stem S communicates with the inner bag via the aerosol valve. By operating the aerosol valve through the stem S, only the content liquid in the inner bag can be ejected and taken out by the pressure of the propellant. And in this dual-structure aerosol container, the propellant remains in the aerosol container as it is even after the content liquid is used up, and by refilling the content liquid in the inner bag, it becomes an aerosol product again. The content liquid can be ejected and taken out.

  The aerosol container for transfer and filling is not limited to a double structure container having a flexible inner bag, and may be a double structure container having another structure such as a double structure container using a cylinder and a free piston. It is sufficient that the propellant and the content liquid are separated and only the content liquid can be injected.

  The actuator 10 used by being attached to such a double-structure aerosol container is composed of, for example, a push button, and includes an actuator body 11 constituting the push button body. A fitting hole 12 into which S is fitted is formed. The lower end portion of the fitting hole 12 is formed in a conical shape so that the fitting to the stem S can be easily performed, and a first horizontal flow path 13 is formed on the upper portion of the fitting hole 12 to communicate with each other. The first vertical flow path 14 is formed and communicated upward from the end of the first horizontal flow path 13.

A large-diameter hole 15 and a small-diameter hole 16 having a step from the center of the upper surface of the actuator body 11 are formed, and an annular hole 17 having the same diameter as the small-diameter hole 16 is formed below the small-diameter hole 16. The inner peripheral corner portion 17 and the upper end portion of the first vertical flow path 14 communicate with each other.
Further, a central hole 18 is formed at the center of the annular hole 17 below the small-diameter hole 16 of the actuator body 11, and a second vertical flow path 19 is formed in communication with the lower portion of the central hole 18. A second horizontal flow path 20 is formed horizontally from the end of the vertical flow path 19.
Also, a large side hole 21 and a small side hole 22 having a step are formed from the center of the side surface of the actuator body 11, and the bottom corner of the small diameter hole communicates with the outer end of the second horizontal channel 20. It is supposed to be.

A transfer / filling member 24 having a transfer / filling port 23 is mounted so as to close the large-diameter hole 15 on the upper surface of the actuator body 11, and a two-stage cylindrical shape is formed by an upper large-diameter cylindrical portion 25 and a lower small-diameter cylindrical portion 26. The actuator body 11 is fitted and attached to the step of the large diameter hole 15 and the small diameter hole 16 and the outer peripheral surface of the annular hole 17.
The cylindrical center of the large-diameter cylindrical portion 25 of the transfer-filling member 24 is the transfer-fill port 23, while the upper portion of the small-diameter cylindrical portion 26 is formed by a conical surface 27, and a communication hole is formed in the bottom of the large-diameter cylindrical portion 25. 28 is formed so as to communicate with the inside of the cylinder of the small diameter cylindrical portion 26.
Thus, the actuator body 11 and the transfer and filling member 24 have the upper part formed as a conical surface 27 below the communication hole 28, the intermediate part as a partial cylindrical part of the small diameter cylindrical part 26, and the lower part as the small diameter cylindrical part 26. A space formed by the annular hole portion and the center hole 18 formed by the inner peripheral surface of the annular hole 17 and the outer peripheral surface of the annular hole 17 is formed, and this space serves as the valve chamber 31 of the automatic switching valve mechanism 30.

  In the valve chamber 31 of the automatic switching valve mechanism 30, the conical surface 27 serves as the upper valve seat 32, and the cylindrical upper surface of the annular hole 17 and the center hole 18 serves as the lower valve seat 33. A backflow prevention valve 34 is mounted as an automatic switching valve.

  The backflow prevention valve 34 is made of an elastic body such as synthetic rubber, and has a valve main body 34a in which a conical body is integrated vertically, and a cylindrical portion 34b is formed at the upper center of the valve main body 34a. The circular plate portion 34c is formed horizontally and the skirt-shaped cylindrical portion 34d protruding downward from the circular plate portion 34c is formed, or the cylindrical portion 34d is omitted as shown in FIGS. The one with the shape is used.

  The injection flow path A and the transfer flow path B are automatically switched by the upper valve seat 32 and the lower valve seat 33 of the valve chamber 31 of the automatic switching valve mechanism 30, from the stem S. A flow path to the valve chamber 31 is mainly a transfer and filling flow path B, and a flow path after the valve chamber 31 is mainly an injection flow path A.

That is, the transfer / filling flow path B is configured from the stem S to the first horizontal flow path 13, the first vertical flow path 14, the communication hole 28 of the transfer / filling member 24, and the transfer / filling port 23.
The injection flow path A is mainly composed of the second vertical flow path 19 after the valve chamber 31, the second horizontal flow path 20, the annular flow path 37 of the injection member 35, and the injection port 36. Up to the chamber 31, a part of the first horizontal flow path 13 and the first vertical flow path 14 of the transfer / filling flow path B is a common flow path.

  In the large side hole 21 and the small side hole 22 opened on the side surface of the actuator body 11, a two-stage cylindrical injection member 35 is fitted and attached to the stepped portion, and the injection member 35 is centered. The outer side is provided with an injection port 36 that expands in a conical shape, and an annular flow path 37 is formed on the inner periphery of the small-diameter cylindrical portion to communicate with the second horizontal flow path 20.

  The injection member 35 is not limited to the one provided with the injection port (mist-like nozzle) 36 that diffuses in the form of a mist according to the injection shape of the content liquid, but has the injection port (gel nozzle) with a small injection angle. Other structures may be used.

  Further, in this actuator 10, a shoulder cover 38 that covers the shoulder of the aerosol container C is mounted, and double cylindrical guide portions 38a and 38b are formed on the upper surface of the aerosol container C. Corresponding to these guide portions 38a, 38b, the actuator body 10 has an annular recess 12a formed on the outside of the stem fitting hole 12, and the annular recess of the actuator body 11 fitted to the stem S by the inside guide portion 38a. The actuator 10 is configured to guide the inner peripheral surface portion of 12a and guide the outer peripheral surface portion of the actuator body 11 and the outer inner peripheral surface portion of the annular recess 12a between the inner guide portion 38a and the outer guide portion 38b. Push button operation (injection and transfer filling) can be performed smoothly.

In such an actuator 10, for example, an aerosol container C1 having a large capacity filled with a propellant having a higher injection pressure than the aerosol container C is used as a parent can for transferring and filling the content liquid.
It should be noted that the present invention is not limited to an aerosol container having a large capacity, and other transfer and filling devices having a higher injection pressure than the aerosol container C may be used.

  When the aerosol container C1 as the parent can is used, the stem S1 of the aerosol container C1 is fitted and connected to the transfer / filling port 23 of the transfer / filling member 24 fitted and attached to the actuator body 11 of the actuator 10. A stem fitting hole 39 is formed.

The aerosol container (child can) C provided with the actuator 10 for the transfer container having the above-described configuration is transferred and filled from the aerosol container (parent can) C1, the aerosol container (child can) C is jetted and stationary. The operation at the time will be described.
As in the past, the aerosol container C is filled with a propellant between the outside of the double-structure inner bag and the aerosol container C.

  At rest, the aerosol valve attached to the aerosol container C is closed, and the stem S and the actuator 10 are shut off. At the time of rest, the backflow prevention valve 34 of the automatic switching valve mechanism 30 in the actuator 10 is in a free state.

Next, when the content liquid in the aerosol container C runs out or at the time of transfer / filling immediately before using the content liquid, the aerosol container C1 is inserted into the stem fitting hole 39 of the transfer / fill port 23 on the upper surface of the actuator 10 of the aerosol container C. The stem S1 is fitted and mounted and pushed in.
Then, each of the aerosol valves of the aerosol container C and the aerosol container C1 is opened via the stems S and S1, and the automatic switching is performed because the pressure of the propellant in the aerosol container C1 is higher than the pressure of the propellant in the aerosol container C. The backflow prevention valve 34 of the valve mechanism 30 is pushed downward.
Thus, the upper valve seat 32 of the valve chamber 31 is opened and the lower valve seat 33 is closed, and the second vertical flow path 19 and the second horizontal flow path 20 after the valve chamber 31 are interposed. The injection flow path A to the injection member 35 is closed.
On the other hand, the skirt-shaped cylindrical portion 34d of the backflow prevention valve 34 is pressed from the outside by the pressure of the propellant in the aerosol container C1, and a gap is formed between the outer peripheral side of the annular hole 17 and the small-diameter cylindrical portion 26 of the transfer filling member 24. And a transfer / filling flow path B communicating with the stem S via the first vertical flow path 14 and the first horizontal flow path 13 is formed, whereby the stem S is placed in the inner bag of the aerosol container C. The content liquid can be transfilled via
Then, after completion of the transfer and filling, by stopping the pushing by the aerosol container C1, the aerosol valves of the aerosol container C1 and the aerosol container C are closed, and the aerosol containers C and C1 return to the stationary state.

Next, when the content liquid is jetted out from the transferred aerosol container C, the actuator 10 is operated to be pushed down as before.
Then, when the stem S of the aerosol container C is pushed down, the aerosol valve is opened, and the backflow prevention valve 34 of the automatic switching valve mechanism 30 is pushed up by the pressure of the content liquid pressurized by the propellant, and the valve chamber 31. By closing the upper valve seat 32, the communication with the transfer filling port 23 is blocked.
At the same time, when the backflow prevention valve 34 is pushed up, the lower valve seat 33 of the valve chamber 31 is opened, and the valve chamber 31 passes through the stem S, the first horizontal flow path 13 and the first vertical flow path 14. The sent content liquid communicates with the annular flow path 37 of the injection member 35 via the second vertical flow path 19 and the second horizontal flow path 20 in the valve chamber 31 to form the injection flow path A. The content liquid is ejected from the ejection port 36 of the ejection member 35.

  By using such an actuator 10, the injection is automatically stopped by the operation of fitting and connecting the aerosol container C1, which is the parent can, without requiring any special operation in either case of transfer filling or injection. In addition to being able to be switched so as to be able to transfer and filling, the transfer and filling is automatically stopped by the injection operation of the actuator 10 and can be switched to the injection state. It can be carried and sprayed.

  Moreover, the aerosol container C for transfer and filling can be used repeatedly, and it is not necessary to purchase an aerosol container having a small capacity each time, which is economical and can reduce waste.

  Similarly, when the shape of the backflow prevention valve 34 of the automatic switching valve mechanism 30 is changed, the switching between the injection flow path A and the transfer flow path B at the time of rest, transfer filling, and injection is performed. 3 and FIG. 4, the same symbols are given to the same members, and duplicate descriptions are omitted.

  Further, the aerosol container C at the time of transfer and filling can be transferred and filled even when it is arranged in the lower direction or conversely when it is arranged in the other direction such as when arranged in the upper direction.

Next, an actuator for a transfer and filling aerosol container provided with an identification means that can prevent filling with a wrong content liquid when transferring and filling will be described.
In this actuator 10A, instead of the stem fitting hole 39 that becomes the transfer filling port 23 of the transfer filling member 24, an identification annular hole 41 is formed concentrically with the communication hole 28 as the identification means 40, and the connection hole 28 An identification groove 42 orthogonal to the upper end surface is formed.
On the other hand, the aerosol container C1 which is a parent can has a tip shape of a stem S1 which can be fitted and fitted into the identification annular hole 41, and a transfer filling nozzle whose tip is larger in diameter than a normal stem S1. 43, which is integrally formed at the tip of the stem S1. It is also possible to form the transfer and filling nozzle 43 part separately from the stem S1 and connect it to the stem S1.

In the actuator 10A provided with such an identification means 40, at the time of transfer and filling, the transfer and filling nozzle 43 at the tip of the stem S1 of the aerosol container C1 is fitted and fitted into the identification annular hole 41 of the actuator 10A and pushed. .
Then, each of the aerosol valves of the aerosol container C and the aerosol container C1 is opened via the stems S and S1, and the automatic switching is performed because the pressure of the propellant in the aerosol container C1 is higher than the pressure of the propellant in the aerosol container C. The backflow prevention valve 34 of the valve mechanism 30 is pushed down, and the injection channel A is automatically closed and the transfer / filling channel B is opened automatically as described above, and the aerosol container C is transferred and filled.

On the other hand, when trying to transfer and fill from the aerosol container C1 having only the normal stem S1, the stem S1 cannot be fitted into the identification annular hole 41, and the liquid in the aerosol container C1 is transferred and filled even if pushed in this state. However, even if the stem S1 is pressed against the upper end surface of the communication hole 28, the content liquid is not transferred and filled by the identification groove 42 but is released into the atmosphere.
As a result, the content liquid in the aerosol container C1 other than the one provided with the transfer filling nozzle 43 in the stem S1 cannot be transferred and can be transferred only with a predetermined content liquid.

Further, in this actuator 10B, instead of the stem fitting hole 39 serving as the transfer filling port 23 of the transfer filling member 24, an identification large-diameter hole 51 is formed in the upper portion of the communication hole 28 as the identification means 50, and this identification is performed. An identification groove 52 orthogonal to the bottom portion of the large-diameter hole 51 is formed.
On the other hand, the aerosol container C1 as a parent can has a tip shape of the stem S1 that can be fitted and fitted into the large-diameter hole 51 for identification, and the tip portion has a larger diameter cylindrical transfer than the normal stem S1. Nozzle adapter 53 is provided. Here, the transfer-fill nozzle adapter 53 is formed separately from the stem S1, and is fitted to the stem S1. It is also possible to integrally form the adapter 53 portion at the tip of the stem S1.

In the actuator 10B provided with such an identification means 50, at the time of transfer and filling, the transfer and filling nozzle adapter 53 at the tip of the stem S1 of the aerosol container C1 is mounted and fitted into the identification large-diameter hole 51 of the actuator 10B and pushed. To.
Then, each of the aerosol valves of the aerosol container C and the aerosol container C1 is opened via the stems S and S1, and the automatic switching is performed because the pressure of the propellant in the aerosol container C1 is higher than the pressure of the propellant in the aerosol container C. The backflow prevention valve 34 of the valve mechanism 30 is pushed down, and the injection channel A is automatically closed and the transfer / filling channel B is opened automatically as described above, and the aerosol container C is transferred and filled.

On the other hand, if an attempt is made to transfer and fill from an aerosol container C1 having only a normal stem S1, a gap is formed when the stem S1 is attached to the large-diameter hole 51 for identification, and the aerosol container cannot be fitted. Even if the content liquid of C1 is discharged to the atmosphere without being transferred or filled, even if the stem S1 is pressed against the upper end surface of the communication hole 28 by the identification groove 52 at the bottom of the large diameter hole 51 for identification, the content liquid is not transferred and filled. To the atmosphere.
As a result, the content liquid in the aerosol container C1 other than the one provided with the transfer filling nozzle adapter 53 in the stem S1 cannot be transferred, and only the predetermined content liquid can be transferred and filled.

  The identification means is not limited to the above embodiment, and the shape of the identification hole on the actuator side and the transfer and filling nozzle on the parent can (double structure aerosol container) side fitted and mounted in the identification hole It is only necessary to have a fitting relationship with no gap (so-called male-female relationship), and not only when using large-diameter holes or annular holes, but also with regular stems such as polygonal shapes, cross shapes, and star shapes. Any shape that cannot be connected is acceptable. Further, the transfer and filling nozzle is not limited to being integrated with the stem, but may be an adapter type that is attached separately.

In addition, in the actuator of this transfer and filling aerosol container, the content liquid to be filled in the aerosol container is not limited at all, and can be widely applied to the content liquid usually used as an aerosol product, especially to be carried around. Is suitable for the preferred contents.
Further, the content liquid to be filled is not limited to a liquid form but can be applied to a gel-like or foam-like content liquid.

As a parent can used for the actuator of such an aerosol container for transfer and filling, it is necessary to ensure a sufficient injection pressure even when the transfer and filling to the child can be repeated, and to ensure a pressure higher than that of the child can.
Therefore, for example, the inner bag of the double-structured parent can is filled with the content liquid, and LPG adjusted to about 0.5 MPa as a propellant is filled between the inner bag and the aerosol container to the extent that the liquid phase exists. Keep it. On the other hand, the double structure can is filled with, for example, nitrogen as a propellant between the inner bag and the aerosol container, and the pressure is set to 0.25 MPa.
When transfer filling is performed using a parent can filled with a propellant having such a liquid phase, the inner bag of the parent can shrinks in accordance with the transfer filling amount, and the volume outside the inner bag increases accordingly, and as a propellant When compressed gas is used, the pressure of the propellant in the parent can decreases, but in this case as well, LPG, which is a liquefied gas, is used as a propellant, causing vaporization from the liquid phase and pressure drop. Is prevented.
In the child can, the content liquid is transferred and filled until an equilibrium pressure with the parent can is reached or an allowable amount in the inner bag is reached.

It has been confirmed by experiments that a predetermined amount of content liquid is transferred and filled in the child can even when such transfer from the parent can to the child can is repeated.
In the experiment, an aerosol container having a filling amount of 120 g was used, and LPG adjusted to about 0.5 MPa as a propellant was filled to the extent that a liquid phase was present. An aerosol container having a filling amount of 20 g was used as a child can, and nitrogen having a pressure of 0.25 MPa was filled as a propellant.
Then, after degassing the inner bag of the child can, the weight of the child can was measured. Next, transfer filling from the parent can to the child can was performed, the weight of the child can after the transfer filling was measured, and the pressure of the child can was measured.
Such transfer filling was repeated 5 times using one parent can, and the measurement results of the child cans in each transfer filling are shown in Table 1.
