Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to hair products, cosmetics, deodorants and antiperspirants, other human products, insecticides, coating agents, cleaners, other household products, industrial products, automobile products, foods, etc. The present invention relates to a push button connected to an aerosol container for filling and spraying contents that are preferably adjusted for spray amount and cooling sensation.

[0002]

2. Description of the Related Art Conventionally, an aerosol container is provided with a mechanism for adjusting a spray amount of contents by a depression amount of a stem, and a small amount of contents is sprayed to reduce a feeling of cooling to a user due to latent heat of evaporation of a propellant. In some cases, the latent heat of vaporization of the propellant is increased by suppressing or spraying a large amount of the content, thereby giving the user a strong cooling sensation in summer or the like.
Also, among other products, there is an aerosol product in which it is preferable to adjust the spray amount of the contents by the amount of depression of the stem.

However, the adjustment of the depression amount of the stem depends on the intuition of the user, and the user cannot know the depression amount without fail and can appropriately adjust the spray amount. Therefore, as in the invention described in JP-A-10-245084, the lower surface of the push button body connected to the stem is
There is one in which an elastically deformable operating piece is protruded, and the operating piece is arranged so as to face a corner which forms irregularities of a component fixed to the aerosol container. The lower end and the corner of this operating piece do not come into contact with the operating piece when the stem is pressed small, and when the stem is pressed strongly, the operating piece crosses over the corner and is elastically deformed. It is arranged in a relationship that gives a feeling.

In this conventional method, when a small amount is sprayed, the operating piece provided on the lower surface of the push button body does not contact the corner formed by the unevenness of the constituent members of the aerosol device, so that the push button body is smoothly pressed. Therefore, there is no resistance to the pressing of the user. Therefore, the user recognizes that the small amount spraying is being performed, and can perform the spraying operation suitable for the small amount spraying.

[0005] When a large pressure is applied, the operating piece of the push button body abuts the corner of the component member of the aerosol device, but is elastically deformable. Get over. The click sensation over the corner is transmitted to the presser, and the presser can recognize that the mode has been switched to the mass spray, and can perform the use suitable for the mass spray.

[0006]

However, in this conventional method, since the operating piece of the push button body only gets over the corner, the click feeling given to the presser is weak.
There is a drawback that it is difficult to transmit to the presser if the user does not press carefully.

The present invention eliminates the above-mentioned drawbacks and provides an aerosol device having a valve function for adjusting the spray amount of the aerosol contents in accordance with the amount of stem depression. At times, the switching feeling is transmitted to the user reliably, and the user can easily and surely adjust the spray amount.

[0008]

According to the present invention, in order to solve the above-mentioned problems, a valve mechanism capable of adjusting the spray amount in accordance with the amount of sliding down of the stem is arranged in the aerosol container and connected to the stem. The one-side engaging projection is provided on the outer side of the push button body, and the other-side engaging projection is provided on the inside of the shoulder cover fixed to the aerosol container. The push button body is arranged to be engageable in the vertical sliding direction, and the arrangement relationship between the one engagement projection and the other engagement projection is not brought into contact with a small pressing of the stem during the spray operation of the aerosol contents, and At the time of the pushing operation of the stem that changes the spray amount, the other or one of the engaging projections moves over the one or the other engaging projection while elastically deforming from the front side to the rear side, so that the clicker of the stem feels a click. Give Those formed by constructed so that.

Further, one or the other engaging projection may be formed of an elastic piece which can be elastically deformed, and the other or one of the engaging projections may be formed of a hard piece which is difficult to elastically deform. good.

In addition, one or the other engagement protrusion projects one, and the other or the one engagement protrusion is formed as a pair facing each other at an interval narrower than the formation width of the one or the other engagement protrusion. It may be something.

Further, one or the other of the engaging projections may be formed by projecting one piece.

Further, the valve mechanism has an upper chamber and a lower chamber formed through an insertion port in a housing having an upper end fixed inside the lid of the aerosol container, and the upper chamber is provided with vaporized gas in the aerosol container. The upper vapor inlet for introducing the gas is opened, and the upper end is urged outward from the lid via a stem gasket, and the lower end pressing portion provided at the lower end is arranged in the upper chamber facing the insertion opening. The lower chamber opens the lower vapor inlet for introducing vaporized gas in the aerosol container, and the lower chamber faces the lower end pressing part of the stem and inserts the pressed part through the lower chamber. A switching valve protruding from the upper chamber side to the upper chamber side is mounted so as to be able to move up and down, a small flow opening communicating the upper chamber and the lower chamber is opened in this switching valve, and the switching valve is a valve with an insertion port And pressed and urged, the insertion opening is closed except in communicating small amounts flow port, when a small pressing of the stem, the
The switching valve may be set in a non-pressed state, and when the stem is largely pressed, the pressed portion of the switching valve may be pressed by the lower end pressing portion of the stem to open the insertion port so that a large amount of contents can be ejected.

[0013]

Since the present invention is constructed as described above, when the small amount of the contents is to be sprayed, the amount of depression of the push button body is reduced. By pushing down the small push button body, the stem is pushed down slightly, the ejection path of the aerosol contents is opened small, and a small amount of contents is ejected to the outside.

Thus, by a small depression of the stem, only a small amount of the contents is sprayed to the outside. In this small-volume spray, the spray of the propellant contained in the aerosol content is also small, and the latent heat of evaporation is small.For example, when the content is a product used for the human body such as an antiperspirant deodorant, the user is asked It will not make you feel too cold. Therefore, it is suitable for use in a cold season such as winter or for a person who does not like the cold feeling. It is also effective when applying a chemical such as a paint or a rust inhibitor to a product in a small area, or when applying it to a small product.

Also, at the time of this small amount spraying, the one engaging projection and the other engaging projection do not come into contact with each other, or even if they come into contact, one or the other engaging projection becomes the surface of the other or one engaging projection. Since the push button body does not move over from the side to the back side, the push button body is pressed smoothly, and the user does not feel resistance to pressing. Therefore, the user can clearly recognize that the small amount spraying is being performed, and can perform the spraying operation suitable for the small amount spraying.

Next, when a large amount of aerosol contents is to be sprayed, the stem is pushed down more than in the case of a small amount of sprays. The depression of the stem is performed by greatly pressing the push button body. Due to the large depression of the stem, the ejection path of the contents is greatly opened, and the contents are sprayed in large quantities to the outside.

Due to the large pressing of the push button main body, the other or one of the engagement projections moves over the one or the other engagement projection while elastically deforming from the front side to the back side. By the end of this movement, one or the other or both of the engagement projections are strongly restored, and at the time of this restoration, a click sound is generated and vibration is applied to the finger of the presser. The click sensation and the restoration sound are clearly transmitted to the presser of the push button body, and the presser can surely recognize that the switch has been made to the large-volume spraying, and can perform use suitable for the large-volume spraying.

For example, by spraying a large amount of the contents, a large amount of the contents can be sprayed on a user's skin, a product, or the like. improves. And, since the propellant contained in the aerosol content is sprayed in a large amount and over a wide area by the large amount spraying of the content, the amount of heat taken away by the latent heat of vaporization of the propellant is large. It gives a strong cooling sensation to the skin of the elderly. Therefore, when used in a hot season such as summer or a person who likes a cold sensation, the strong cold sensation gives a comfortable refreshing sensation. In addition, even when the affected part generates heat due to sprains or the like, this large amount of spray allows the affected part to be quickly cooled and treated. In addition, it is possible to quickly apply a paint or a chemical to a product over a large area.

As described above, the feeling of switching between the small amount spray and the large amount spray by the pressing amount of the stem is clearly transmitted to the user, so that the user can easily and reliably adjust the spray amount.

Further, the one or other engaging projection may be formed by an elastic piece that can be elastically deformed, and the other or one engaging projection may be formed by a hard piece that is difficult to elastically deform.

Either one or the other of the engagement projections can be used as long as the other or one of the engagement projections can move over the one or the other engagement projection while elastically deforming from the front side to the rear side. The projection may also be formed of an elastic piece that can be elastically deformed.

Further, one or the other engagement protrusion projects one, and the other or the one engagement protrusion is formed as a pair facing each other at an interval narrower than the formation width of the one or the other engagement protrusion. It may be something. As described above, by forming one or the other pair of engagement protrusions, the restoration sound and the click feeling can be increased, and even if one of the pair is damaged, the restoration sound or the click sound is caused by the presence of the other piece. A feeling can be obtained, and operation stability can be maintained.

Further, one or the other of the engaging projections may be formed by projecting one piece. In this case, the configuration can be simplified, and the product can be obtained at low cost.

Further, if the spray amount of the aerosol contents can be adjusted in accordance with the sliding amount of pushing down the stem,
An aerosol device can be formed using an appropriate valve mechanism. Then, a push button body provided with an operation piece is connected to the aerosol device. Various conventionally known configurations can be used for the valve mechanism for adjusting the spray amount.

The above-mentioned aerosol container is used for hair products, cosmetics, deodorant / antiperspirants, other human body products, insecticides, coating agents, cleaners, other household products, industrial products, automobile products, foods and the like. The spray amount control can be used for the preferable contents.

The stem (9) has a lower end pressing portion (13) provided at the lower end facing the insertion opening (5) separating the upper chamber (7) and the lower chamber (8).

On the other hand, the lower chamber (8) is provided with an aerosol container (1).
A lower vapor inlet (26) through which vaporized gas inside can be introduced into the lower chamber (8) is opened vertically above the lower chamber (8). A switching valve (14) is vertically movably mounted in the lower chamber (8). This switching valve
(14) The body portion is formed in a cylindrical shape having a U-shaped cross section, and the upper end side is formed in a cylindrical shape to form a pressed portion (15), and the pressed portion (15) is inserted into the insertion port (5). Through the upper chamber
(7) It protrudes to the side.

The pressed part (15) has a small flow opening (16) through which a small amount of aerosol contents can flow. Further, the switching valve (14) is provided between the upper end of the inner surface of the cylindrical portion having a U-shaped cross section and the lower bottom of the lower chamber (8).
(17), the switching valve (14) is constantly pressed in the direction of the insertion port (5), and the partition wall constituting the valve seat (18) of the insertion port (5).
(6) is pressed against the lower surface.

The switching valve is pressed by the pressing of the pressing line (17).
In a state where (14) is in close contact with the valve seat (18), the communication between the lower chamber (8) and the upper chamber (7) is performed only through the small flow port (16), and the lower vapor inlet ( 26) and upper chamber
(7) is a non-communication state. The lower chamber (8) is formed with a flow groove (20) in the vertical direction facing the outer periphery of the switching valve (14) so that a large amount of aerosol contents can flow.

The switching valve (14) is provided with a pressed portion (15) protruding toward the upper chamber (7) and a lower pressing portion of the stem (9).
It is arranged facing (13). When the stem (9) is strongly pressed, the switching valve is provided by the lower end pressing portion (13).
The pressed part (15) of (14) can be pressed, and when the stem (9) is pressed slightly, the stem gasket (3)
The orifice (12) is formed so that it only releases the hermetic relationship and does not press the pressed portion (15).

An inlet 21 for aerosol contents is formed at the lower end of the lower chamber 8 of the housing 4, and a dip tube 22 is connected to the inlet 21. .

The stem (9) can be pushed down by connecting a push button body (28) to the upper end of the stem (9) of the valve mechanism (27) as described above. On one side of the push button body (28), an injection nozzle (30) is formed so as to protrude, so that the contents passing through the ejection path (11) of the stem (9) can be ejected from the injection nozzle (30) to the outside. I have. And a shoulder cover (31) is attached to the lid (2) of the aerosol container (1).
And the shoulder cover (31) and the push button body (28) are connected via a hinge (32) as shown in FIG.

The push button body (28) has an injection nozzle.
A one-side engaging projection (33) protrudes outward on the side surface opposite to (30). On the other hand, the engagement projection (33) has a thickness that is difficult to elastically deform and protrudes from the push button body (28).

The other engaging projection (34) is provided inside the shoulder cover (31) fixed to the aerosol container (1). The other engagement projection (34) is the one engagement projection.
(33), facing each other at an interval smaller than the width of the shoulder cover,
(31) is formed as a pair and is formed so as to be elastically deformable.

The one engagement projection (33) and the other engagement projection (34) are arranged to be engageable in the vertical sliding direction of the push button body (28). Also, the one-side engaging projection
The arrangement relationship between (33) and the other engaging projection (34) is such that the small contact of the stem (9) during the spraying operation of the aerosol contents does not make contact with the other, and the one-sided pressing relationship of the stem that changes the spray amount. The engagement projection (33) is the other engagement projection.
From the front side to the rear side of (34), the other engaging projection (34) is arranged to move over while elastically deforming.

The distance between the lower surface of the one engagement projection (33) and the upper surface of the other engagement projection (34) is equal to the distance between the lower end of the stem (9) and the upper surface of the switching valve (14) when not pressed. When the stem (9) pushes down the switching valve (14) to switch to the large-volume spraying, one of the engaging projections (3
3) abuts on the other engaging projection (34), gets over it, and moves to the back side of the other engaging projection (34). Sound is transmitted. Therefore, the switching to the large-volume spraying and the transmission of the click feeling and the restoration sound to the presser are linked, so that the spraying amount can be reliably adjusted.

Also, one engagement projection (33) and the other engagement projection are provided.
As described above, (34) forms one engagement projection (33) and a pair of other engagement projections (34), but in another embodiment, as shown in FIG. The other engaging projection
Each of (33) and (34) may be formed by projecting one piece.

FIGS. 3 and 4 show a state in which the aerosol contents are not injected in the above-described structure.
As shown in the figure, the stem (9) is in a non-pressed state,
The orifice (12) of the stem (9) is urged outward by the pressing force of (10), and the stem gasket (3)
Are sealed by the inner peripheral end surface of the. Also, the lower end pressing portion (13) of the stem (9) and the switching valve (14)
A fixed interval is formed between the pressed portion (15) and
Depending on the small amount of pressing of the stem (9), the switching valve (14)
Are provided so as not to be pressed.

When a small amount of aerosol contents is to be injected, as shown in FIGS.
(9) is pressed with a small pressing force by a small amount. In this state, the lower end pressing portion (13) of the stem (9) does not press the pressed portion (15) of the switching valve (14) as shown in FIGS. The sealing relationship between the inner peripheral end face of (3) and the orifice (12) is released, but the switching valve (14)
Is not pressed. Since the switching valve (14) is in a non-pressed state, the upper chamber (7) and the lower chamber (8) communicate with each other only through the small flow port (16).

In this state, the contents of the aerosol flow into the housing (4) through the dip tube (22), the inflow port (21), and the lower chamber (8). As shown, the inflow into the upper chamber (7) takes place only through the small flow openings (16). Therefore, the ejection amount of the aerosol contents is limited only to the amount that flows through the small amount circulation port (16).
In the housing (4), an upper vapor inlet (25) of the upper chamber (7) and a lower vapor inlet (2) of the lower chamber (8) are provided.
The vaporized gas in the aerosol container (1) flows in through (6). However, since the insertion port (5) is closed, the vaporized gas in only the upper vapor inlet (25) enters the upper chamber (7). And vaporized gas from the lower vapor inlet (26) flows into the upper chamber.
It does not flow into (7).

Then, in the upper chamber (7), a small amount of the vaporized gas and a small amount of the aerosol content are mixed, and this mixture is supplied through the orifice (12) of the stem (9) to the jet passage (11). Leaked to Then, the aerosol content is atomized by the crushing force of the vaporized gas, and is sprayed in a small amount to the outside via the spray nozzle (30). Further, since the ratio of the vaporized gas to the contents of the aerosol is appropriate, the aerosol contents can be finely atomized, and the coating can be performed without causing dripping or uneven coating.

In this state, the one engaging projection 33 and the other engaging projection 34 do not come into contact with each other. The restoring sound of the joint projection (34) is not transmitted, and the presser can recognize that the small amount of spraying is being performed.

As described above, when it is preferable to spray a small amount of the contents, the push button body (28) can be pressed with a small amount of pressing, and the position of the push button body (28) can be held without feeling a click feeling. It will be good. For this reason, when the paint is applied to a small area, the paint is not wastefully used by thick coating, and the dripping can be prevented. Further, since the spraying amount of the propellant is small, the latent heat of evaporation is also small, so that a product used for the human body does not give the user a strong cooling sensation. Therefore, it becomes possible to use in cold seasons such as winter, for use by people who do not like cold sensation, and when cold stimulus such as wound medicine is not preferable.

Next, when a large amount of aerosol contents is to be sprayed, as shown in FIGS.
Into the aerosol container. In response to the pushing of the large stem (9), the pressed portion (15) of the switching valve (14) is moved to the lower end pressing portion of the stem (9) as shown in FIG.
It is pressed by (13) and separates from the valve seat (18). Therefore, the closing of the insertion port (5) by the switching valve (14) is released, and the aerosol content flowing from the dip tube (22) and the inflow port (21) passes through the insertion port (20) through the flow groove (20). 5), and flows into the upper chamber (7) from the insertion port (5). Then, the aerosol content is supplied to the small amount distribution port (1
Since it is introduced into the upper chamber (7) also from 6), a large amount of aerosol contents can be injected from the upper chamber (7) to the outside through the orifice (12).

Further, vaporized gas for crushing the contents of the aerosol flows into the upper chamber (7) from the upper vapor inlet (25), and also flows from the lower vapor inlet (26) to the lower chamber.
(8) The vaporized gas flowing into the upper chamber from the insertion port (5)
(7). By introducing this large amount of vaporized gas,
A large amount of aerosol content will also be well crushed into a fine mist. Therefore, as in the case of the small-volume injection, it is possible to jet the aerosol contents without causing dripping or uneven coating.

When the switching valve (14) is depressed to switch to large-volume spraying, a large pressing of the push button body (28) causes the one-side engaging projection provided on the push button body (28).
(33) abuts the other engagement projection (34) of the shoulder cover (31). This one engagement projection (33) or the other engagement projection
(34) is elastically deformable, so that the pushbutton body (2
8), as shown in FIG.
3) elastically deforms over the other engaging projection (34) and gets over it, and moves to the back side of the other engaging projection (34). The impact generated when the one engagement projection (33) gets over the other engagement projection (34) gives the pressing person a click feeling. When the one engagement projection (33) elastically deforms the other engagement projection (34) and moves to the back side of the other engagement projection (34), the other engagement projection (34) is rapidly restored to the original position. However, the restoring sound generated at the time of restoring also allows the presser to clearly recognize the switch to the large-volume spray.

Since a large amount of contents can be sprayed on a large area by mass spraying, work time can be reduced and work efficiency can be improved. In addition, since a large amount of the content is sprayed, the propellant is also sprayed in a large amount, so that a large amount of latent heat of vaporization is lost. for that reason,
In the case of a product used for the human body, a strong cooling sensation is given to the user, and a good cooling sensation is given to the user when used by a person who likes a hot season such as summer or a cooling sensation. It is also suitable for spraying a large area or a large amount of other coating agents, cleaners, other household goods, industrial goods, automobile goods, foods, and the like.

As described above, the feeling of switching from the small amount spraying of the contents to the large amount spraying is the click feeling and the one-side engaging projection (33).
Alternatively, since the restoration sound of the other engagement projection (34) is clearly transmitted to the user, the user can use this switching feeling as a clue,
It is possible to easily and reliably adjust the spray amount of the contents, and to use one aerosol product properly according to the purpose of use and preference.

After the end of the mass spraying, the push button body (28)
By releasing the pressing, the push button body (28)
It is restored to the original position by the restoring force of (9).
(33) also restores the other engagement projection (34) to its original position by elastically deforming it.

In the above embodiment, the one-side engaging projection (33)
Is hard and not deformed, and a restoring sound is generated by elastically deforming the other engaging protrusion (34). Either the one engaging protrusion (33) or the other engaging protrusion (34) is used. May be formed of an elastic piece that can be elastically deformed, and the corresponding engagement projection may be formed of a hard piece that is difficult to elastically deform.

In the above embodiment, the push button body (28) and the shoulder cover (31) are connected by the hinge part (32). However, as shown in FIG. 10, the push button body is not provided with the hinge part (32).
(28) and the shoulder cover (31) may be separate.

Further, in each of the above embodiments, the one engaging projection (33) or the other engaging projection (34) is formed by an elastic piece that is elastically deformable or a hard piece that is difficult to elastically deform. The elastic piece and the hard piece may be formed by using an elastic material or a hard material as the material of the one engaging protrusion (33) or the other engaging protrusion (34). Thereby, it is good also as an elastic piece and a hard piece.
