The present invention relates to a push button for an aerosol container for spraying.
[0002]
[Prior art]
Conventionally, there is an invention described in Japanese Patent No. 2968944 that adjusts the injection amount of the aerosol contents by the downward sliding amount of the stem. According to the present invention, a small amount of injection can be performed by pushing down the stem small, and a large amount of injection can be performed by pressing down the stem largely. The purpose of selectively using small injection and large injection is, for example, in the case of small injection, it is possible to inject an appropriate amount of aerosol content in a narrow space, and in the case of large injection, the aerosol content is efficiently injected into a wide space. It is possible to inject.
[0003]
[Problems to be solved by the invention]
However, the adjustment of the stem push-down amount is not performed with a clear mark or response, but relies on the user's intuition, so the user knows the push-down amount reliably and switches the injection mode appropriately. Was difficult.
[0004]
In order to eliminate the drawbacks as described above, the present invention is an aerosol device having a valve function that adjusts the injection amount of the aerosol contents in accordance with the amount of depression of the stem, and switches between small injection and large injection. The user can reliably and easily switch without relying on intuition and the like to efficiently inject the aerosol contents.
[0005]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention has a valve mechanism that can adjust the injection amount corresponding to the amount of sliding down of the stem in the aerosol container, and the stem can be pushed down by a push button connected to the upper end of the stem. In addition, a rotating plate is arranged in the push-down movement range of the push button, and one end of the rotating plate is pivotally supported on a part of the fixed body to the aerosol container and is pushed on the rotating plate. Side of the push button in the non-pressed state of the push button, a large protrusion that makes it impossible to push down the push button, a small protrusion that allows the push button to be pushed down, and a protrusion that allows the push button to be pushed down largely And forming these large protrusions, small protrusions, and non-forming portions of the protrusions in the range of movement of the push buttons as the rotating plate rotates, and forming them in a color different from that of the rotating plate. The fixed body is provided with display openings of different sizes or shapes facing the rotation destination of the rotating plate at the time of mass injection and small quantity injection, and the push button is pushed by the rotation plate displayed on this display opening That can confirm the amount that can be pushed down In addition, the rotating plate projects the other end opposite to the shaft support to the fixed body to the outside from the sliding long hole provided on the side surface of the fixed body, and the inside of the sliding long hole is in the circumferential direction. The operation lever can be operated with a finger and can be operated with a finger, and the operation lever is temporarily engaged with the non-injection position of the aerosol contents with an elastic piece protruding from the surface of the sliding slot. At the time of mass injection and small amount injection of objects, the rotating plate can be rotated by overcoming this elastic piece with a certain force or more. It consists of
[0006]
In addition, the valve mechanism forms an upper chamber and a lower chamber through an insertion port in a housing whose upper end is fixed inside the lid of the aerosol container, and the upper chamber is covered by a stem gasket in the upper chamber. A stem that is urged outward from the body and that has a lower end pressing portion provided at the lower end facing the insertion opening is mounted to be movable up and down, and the lower chamber is exposed to the lower end pressing portion of the stem and covered. A switching valve that protrudes from the insertion port to the upper chamber side is mounted so that it can move up and down, and a small-volume flow port that connects the upper chamber and the lower chamber is opened in this switching valve and the switching valve is connected to the insertion port. The valve seat is pressed and urged, and the insertion port is closed except for communication with a small amount of flow port. When the stem is pressed slightly, the switching valve is not pressed, and when the stem is pressed large, it is switched by the lower end pressing part of the stem. Valve pressure The presses, a large amount of contents to open the insertion port may be possible injection.
[0007]
[Action]
Since the present invention is configured as described above, when injecting the aerosol contents, it is necessary to switch to small injection or large injection in accordance with the purpose of use, the injection space, and the size of the coating area. Can do. This switching is performed by rotating the rotating plate to the small amount injection side or the large amount injection side, and a display opening having a different size or shape is provided at each of the rotation destinations. Therefore, the operator can clearly confirm the pushable amount of the push button at each rotation destination, and can accurately arrange the rotation plate according to the target injection form.
[0008]
Further, the fixed body and the rotating plate are formed in different colors. For example, if the fixed body is formed in red and the rotating plate is formed in yellow, the yellow of the rotating plate is clearly displayed through the display opening of the red fixed body. Yes. Furthermore, if the display opening is formed in a small triangle shape on the small-quantity injection side and a large triangle shape on the large-volume injection side, for example, the amount of push button that can be pushed down can be clearly confirmed by the size of the triangle, and the injection form can be reliably and easily You can switch.
[0009]
This display opening may be a square, star, round, or the like having a different size, a different shape, or a simple character. Further, it may be a large triangular display opening connected from the small injection position to the large injection position.
[0010]
And when performing small amount injection of the aerosol content, a rotation plate is rotated and arrange | positioned at the display opening side for small amount injection provided in the fixing | fixed part. Thus, by rotating the rotating plate to the small amount injection side, the small protrusion of the rotating plate is arranged on the lower surface of the push button. When the push button is pressed in this arrangement state, the push button comes into contact with the small protrusion, so that the large push-down cannot be performed, and only a small push is possible.
[0011]
By pressing the small push button, the stem is pushed down small, and the spray passage of the aerosol content is opened small, so that a small amount of the aerosol content is injected to the outside. Therefore, it is possible to efficiently and efficiently spray the aerosol contents to the application portion having a narrow space or a small area. In addition, it is not necessary for the operator to adjust the pressing amount of the push button, and it is sufficient to press until the push button hits the small protrusion, so there is no insufficient pressing or excessive pressing, and an appropriate pressing amount is always provided. With this, small amount injection can be performed satisfactorily.
[0012]
Next, when a large amount of aerosol content is to be ejected, it is necessary to push down the stem much more than in the case of a small amount. For this purpose, by rotating the rotating plate to the mass injection position, the non-formed portion of the protrusion is arranged facing the lower surface of the push button. Even on the large-quantity injection side, since the display opening having a different size and shape from the small-quantity injection is provided in the fixed body, the rotation plate can be accurately aligned.
[0013]
As described above, in a state where the protrusion non-forming portion is arranged in the movement range of the push button, the rotation plate does not prevent the push button from being lowered, and the push button can be largely pressed. By pressing the large push button, the stem is largely pushed down, and the ejection passage of the aerosol contents is largely opened, so that the aerosol contents can be ejected in a large amount to the outside. By this mass injection, it becomes possible to quickly and efficiently inject the aerosol contents into a large space or a large area to be coated.
[0014]
In the present invention, it is possible to prevent erroneous injection of aerosol contents even when a pressing force is applied to the push button due to an impact or mischief during transportation, dropping or storage of the aerosol product. For this purpose, the rotation plate is rotated, and the large protrusion of the rotation plate is arranged in the push-down movement range of the push button. With this arrangement, the large protrusion is brought into contact with the lower surface of the push button, so that even if the push button is intentionally or mistakenly pressed, the push button hits the large protrusion and the push button cannot be pushed down. Therefore, the stem is not pushed down by the push button, the valve mechanism is kept closed, and the aerosol contents are not mistakenly injected outside.
[0015]
In this way, the spray form of the aerosol contents can be arbitrarily switched according to the purpose of use, the spray space, and the area of application, and the aerosol contents can be used efficiently. Further, switching between the small quantity injection and the large quantity injection can be performed easily and accurately simply by rotating the rotating plate according to the display opening, and a product with excellent operability can be obtained. Further, the large protrusion provided on the rotating plate is brought into contact with the push button, whereby the erroneous injection of the aerosol contents can be surely prevented, and the safety of the product is increased.
[0016]
Moreover, as long as a rotation plate can arrange | position the large protrusion, a small protrusion, and the non-projection part of a protrusion on the lower surface of a pushbutton corresponding to an injection form, you may form a rotation means suitably. For example, the other end on the opposite side of the shaft support to the fixed body protrudes outside from a sliding long hole provided on the side of the fixed body, and the operation lever that can be slid in the sliding long hole and can be operated with fingers Then, the rotation operation of the rotation plate can be easily performed, and the rotation plate can be stably rotated.
[0017]
Further, the rotating plate is an elastic piece protruding from the surface of the sliding long hole, and the operating lever is temporarily engaged with the non-injection position of the aerosol contents. You may form so that rotation of a rotation plate is possible by getting over an elastic piece with more than fixed force. If formed in this way, even if a slight impact is applied to the rotating plate disposed at the non-injection position of the aerosol contents, the erroneous injection prevention function is easily released by rotating to the aerosol contents injection side. It can be kept safe. And when it is going to inject an aerosol content, it can switch to a small injection or a large injection by operating an operation lever with a force more than fixed, and can inject an aerosol content outside.
[0018]
In addition, the structure of the valve mechanism that can adjust the spray amount of the aerosol content corresponding to the amount of sliding down of the stem is formed in the upper chamber through the insertion opening in the housing whose upper end is fixed inside the lid of the aerosol container. And a lower chamber. Then, a stem disposed with a lower end pressing portion provided at the lower end facing the insertion opening and movably moved up and down is mounted in the upper chamber through a stem gasket. A switching valve that faces the lower end pressing portion of the stem and protrudes from the insertion port to the upper chamber side is mounted in the lower chamber so as to be movable up and down. Open a small-volume distribution port that communicates. Then, the switching valve is pressed and urged against the valve seat of the insertion port, and the insertion port is closed except for communication with a small amount of flow port. When the stem is pressed slightly, the switching valve is set to a non-pressed state, and when the stem is pressed largely The pressed portion of the switching valve is pressed by the lower end pressing portion of the stem, and the insertion port is opened to form a large amount of aerosol contents.
[0019]
A rotating plate and an appropriate push button are connected to the outer periphery of the stem of the valve mechanism formed as described above. The large protrusion of the rotating plate is formed with a size that contacts the lower surface of the push button in a non-pressed state of the push button and prevents the lowering. In addition, the small protrusion has a dimension that when the push button is pressed and hits the small protrusion, the stem is pushed down by a small amount to open the valve mechanism, but the lower end pressing portion of the stem does not press the switching valve. Together.
[0020]
With such a configuration, only the aerosol content that has passed through only the small-quantity distribution port is ejected to the outside, and the aerosol content can be ejected in a small amount. And when the projection non-formation part is arranged in the movement range of the push button, the push button can be largely pressed and the pressed part of the switching valve can be pushed by the lower end pushing part of the stem so that the insertion port can be opened. It is possible to form a large amount of aerosol contents.
[0021]
The aerosol container push button of the present invention is suitable for the injection of aerosol contents such as insecticides, cleaners, deodorants, other household products, cosmetics, other human body products, industrial products, automobile products, foods and the like. . And as an insecticide, it can use for a space insecticide, a cockroach insecticide, a gardening insecticide, an acaricide, an unpleasant insect insecticide, etc.

【Example】
Hereinafter, one embodiment of the present invention will be described with reference to the drawings. (1) is an aerosol container filled with an aerosol content, and a lid (2) is fixed to the upper end. A housing (4) is fixed to the inner surface of the lid (2) via a stem gasket (3). As shown in FIGS. 1 and 6, an annular partition wall (5) formed separately from the housing (4) is inserted into the housing (4), and the annular partition wall (5) is disposed. The housing (4) is divided into an upper chamber (6) and a lower chamber (7). In addition, the partition wall (5) has an insertion port (8) opened at the center so that the upper chamber (6) and the lower chamber (7) can communicate with each other.
[0026]
The upper chamber (6) of the housing (4) is fitted with a stem (10) whose upper end protrudes outward from the lid (2) so as to be movable up and down. The stem (10) is pressed and urged upward by the stem ridge (11), and an ejection path (12) for the aerosol contents is formed in the axial direction at the upper end, and the ejection path (12) The communicating orifice (13) is opened from the side.
[0027]
The orifice (13) is normally sealed by the inner peripheral end face of the stem gasket (3), and is in close contact with the inner peripheral end face of the stem gasket (3) in a state where the stem (10) is pushed down. The housing (4) is configured to be able to communicate with the outside and the outside. Moreover, the stem (10) has a lower end pressing portion (14) provided at the lower end disposed so as to face an insertion port (8) that separates the upper chamber (6) and the lower chamber (7).
[0028]
On the other hand, a switching valve (15) is mounted in the lower chamber (7) of the housing (4) so as to be movable up and down. The switching valve (15) has a body portion formed in a U-shaped cylindrical shape and an upper end projecting in a columnar shape to form a pressed portion (16). The pressed portion (16) is an insertion port. It protrudes to the upper chamber (6) side through (8).
[0029]
The pressed portion (16) is provided with a small-quantity distribution port (17) through which a small amount of aerosol content can be distributed. Further, the switching valve (15) is interposed between the lower bottom (7) and the lower bottom of the lower chamber (7) by pressing the switching valve (15) in the direction of the insertion port (8). The switching valve (15) is brought into close contact with the valve seat (20) of the insertion port (8). In a state where the switching valve (15) is in close contact with the valve seat (20), the communication between the lower chamber (7) and the upper chamber (6) is performed only through the small-volume flow port (17).
[0030]
When the stem (10) is largely pressed, the pressed portion (16) of the switching valve (15) can be pressed by the lower end pressing portion (14), and the upper chamber (6), the lower chamber (7), Can be communicated through the insertion port (8). However, the small pressing of the stem (10) only releases the sealing relationship between the stem gasket (3) and the orifice (13), and does not press the pressed portion (16). ) To keep the insertion port (8) closed. The housing (4) has a dip tube (22) connected to the inlet (21) of the aerosol contents to the lower chamber (7).
[0031]
A push button (24) is connected to the stem (10) of the valve mechanism (23) formed as described above so that the stem (10) can be pushed down. The push button (24) forms an injection nozzle (25) on one side, and the aerosol contents that have passed through the injection passage (12) of the stem (10) can be injected from the injection nozzle (25) to the outside. . Then, the push button (24) is connected to the fixed body (26) via the hinge portion (38), and the fixed body (26) is engaged and fixed to the lid body (2) of the aerosol container (1). Yes.
[0032]
In the fixed body (26), the rotational amount of the push button (24) is regulated by disposing the rotating plate (28) in the movement range (27) when the push button (24) is pushed down. The amount of aerosol spray can be adjusted. As shown in FIG. 1, the rotating plate (28) has a stem (10) inserted through an insertion slot (30) provided in the center and one end pivotally supported by a fixed body (26). ing. Further, the rotating plate (28) projects the other end opposite to the shaft supporting portion (31) to the outside from the sliding long hole (32) opened in the side surface of the fixed body (26), and is moved with fingers. An operable lever (33) is provided. By operating this operating lever (33) with fingers and sliding in the sliding slot (32) in the circumferential direction, the rotating plate (28) is moved in the circumferential direction via the shaft support (31). Can be rotated.
[0033]
Further, as shown in FIGS. 1 to 3, the rotating plate (28) is brought into contact with the lower surface of the push button (24) in the non-pressed state of the push button (24), as shown in FIGS. A large protrusion (34) is provided that makes it impossible to push down (24). Furthermore, a small protrusion (35) is provided on one side of the large protrusion (34) to enable the push button (24) to be pressed down. In order to ensure the engagement with the large protrusion (34) and the small protrusion (35), the push button (24) has a part of the outer periphery of the connection portion with the stem (10) protruding outward. As shown in FIGS. 1 and 2, an engagement rib (36) is provided.
[0034]
As shown in FIGS. 2 and 4, the large protrusion (34) is a push button (when the operation lever (33) of the rotating plate (28) is placed at the center of the sliding slot (32). 24) is formed so as to be in contact with the lower surface of the engagement rib (36). The small protrusion (35) is small when the operating lever (33) is rotated from the position of the large protrusion (34) to one side on the back side of the push button (24) shown in FIGS. The protrusion (35) is formed so as to be disposed on the lower surface of the push button (24).
[0035]
Further, when the operation lever (33) is rotated from the position of the large protrusion (34) to the other, the protrusion non-forming part (37) is arranged on the lower surface of the engagement rib (36) of the push button (24). The alignment is as follows. Due to the disposition of the non-forming portion (37) on the lower surface of the engagement rib (36), the engagement rib (36) does not hit the large protrusion (34) or the small protrusion (35), and the push button (24) is large. It can be pushed down.
[0036]
In this embodiment, the rotating plate (28) is formed in yellow, and the push button (24) and the fixed body (26) are formed in red, so that they are formed in different colors. As shown in FIG. 5, the fixed body (26) is provided with a display opening (40) by cutting out the surface on the side where the operation lever (33) is located at the time of small amount injection into a small triangle shape. . Further, a display opening (41) having a triangular shape larger than the display opening (40) for small amount injection is also provided on the surface on which the operation lever (33) is located at the time of mass injection.
[0037]
As described above, since the display openings (40) and (41) are provided in triangular shapes having different sizes for the small amount injection and the large amount injection, the rotation direction of the operation lever (33) corresponding to the injection mode is set as follows. The operator can distinguish at a glance. Further, when the rotating plate (28) moves to the small quantity injection and mass injection side, the yellow rotating plate is displayed through the display openings (40) (41) of the fixed body (26) formed in red. Since (28) is displayed, the operator can easily rotate the rotating plate (28) to an accurate position corresponding to the pushable amount of the push button (24).
[0038]
Further, as described above, when the large protrusion (34) and the engaging rib (36) are engaged and the rotating plate (28) is at the non-injection position of the aerosol contents, the operation lever (33) Is located in the center of the sliding slot (32). In this central position, the sliding slot (32) is provided with an arc-shaped elastic piece (42) as shown in FIG. 4, and this elastic piece (42) is provided at the lower end of the operating lever (33). Temporarily engage with the engaging recess (43). By this engagement, the operation lever (33) is not easily rotated even if a slight impact is applied by transportation or the like, and the non-injection state of the aerosol contents can be maintained.
[0039]
When the aerosol contents are ejected, the operation lever (33) is moved over the elastic piece (42) while being elastically deformed by operating the operation lever (33) with a certain force or more. It is assumed to rotate to the injection side. Further, even if the rotation destination is not operated with a certain force or more, the operation lever (33) does not easily return to the original position over the elastic piece (42). Therefore, the rotation plate (28) is stably temporarily engaged at the rotation destination, and it is possible to smoothly perform a small amount injection and a large amount injection of the aerosol contents.
[0040]
Further, in order to enable switching of the injection mode of the valve mechanism (23) corresponding to the pressing amount of the push button (24) due to the restriction of the rotating plate (28), the engagement rib (36) of the push button (24). The distance between the lower surface of the projection and the upper surface of the small projection (35) is substantially the same as or slightly shorter than the distance between the lower end of the stem (10) and the upper surface of the switching valve (15) when not pressed. Then, when the push button (24) is pressed and abutted against the small protrusion (35), the stem (10) is pushed down to open the valve mechanism (23), but the lower end pressing portion of the stem (10) is opened. (14) does not push down the switching valve (15), and a small amount of aerosol content can be injected. Further, when the push button (24) is largely pressed by disposing the protrusion non-forming portion (37) of the rotating plate (28) on the lower surface of the push button (24), the lower end pressing portion ( 14) pushes down the switching valve (15) and opens the insertion port (8), so that a large amount of aerosol contents can be injected.
[0041]
When the aerosol contents are not jetted in the configuration as described above, as shown in FIG. 4, the operating lever (33) of the rotating plate (28) is moved to the sliding slot (32). Place it in the center of With this arrangement, as shown in FIGS. 1 and 2, the large projection (34) of the rotating plate (28) comes into contact with the lower surface of the engagement rib (36) of the push button (24), and the push button (24). Can not be pushed down. Accordingly, even if the push button (24) is intentionally pressed or any impact force is applied to the push button (24), the push button (24) does not descend and push down the stem (10). (23) is not opened, and erroneous injection of aerosol contents can be reliably prevented.
[0042]
Further, as shown in FIG. 4, the operating lever (33) of the rotating plate (28) is temporarily engaged by the elastic piece (42), so that some external force such as vibration and rear-end collision is applied to the operating lever (33). In addition, the rotating plate (28) does not rotate in the direction in which the aerosol contents are injected, and the non-injecting state can be maintained.
[0043]
And when performing the injection of the aerosol content, an injection form can be arbitrarily selected according to the purpose of use, the injection space, and the width of the application area. First, when it is desired to inject a small amount of the aerosol contents, the operating lever (33) is rotated leftward with a certain force or more against the engaging force of the elastic piece (42). As shown, the red rotating body (26) is arranged at a position where the yellow rotating plate (28) is displayed through the display opening (40) indicated by a small triangle. Even at this rotation destination, the operating lever (33) is temporarily engaged by the elastic piece (42), so that the rotating plate (28) can be moved even if the operator releases the finger from the operating lever (33). There is no restoration to the non-injection position.
[0044]
By this rotation toward the small amount injection side, the small protrusion (35) of the rotation plate (28) is arranged on the lower surface of the engagement rib (36) of the push button (24). When the push button (24) is pressed in this arrangement state, the push button (24) is lowered by a small amount, and then the engagement rib (36) hits the small protrusion (35) and stops. Due to the small lowering of the push button (24), as shown in FIG. 7, the stem (10) is pushed into the housing (4) by a small amount, and the sealing relationship between the inner peripheral end face of the stem gasket (3) and the orifice (13) However, the lower end pressing portion (14) of the stem (10) does not press the pressed portion (16) of the switching valve (15), and the upper chamber (6) and the lower chamber (7) Is communicated only via the small-quantity distribution port (17).
[0045]
In this state, the aerosol content in the aerosol container (1) flows into the lower chamber (7) of the housing (4) through the dip tube (22) and the inlet (21). The inflow into the upper chamber (6) is performed only through the small-volume flow port (17). Therefore, the spray amount of the aerosol content from the spray nozzle (25) to the outside is limited only to the amount that flows through the small flow port (17). Therefore, it is possible to inject a small amount of the aerosol contents, and it is possible to efficiently inject an appropriate amount even in a narrow space and a coated area having a small area.
[0046]
Next, when a large amount of aerosol content is to be ejected, the operating lever (33) is rotated to the right, and the rotating plate is placed on the display opening (41) side of the fixed body (26) indicated by a large triangle. (28) is arranged. With this arrangement, the projection non-forming part (37) of the rotating plate (28) is arranged at a position facing the engagement rib (36) of the push button (24). Accordingly, the lowering of the push button (24) is not hindered by the large protrusion (34) or the small protrusion (35), and the push button (24) can be largely pushed down.
[0047]
By the large depression of the push button (24), the stem (10) is largely pushed into the aerosol container (1) as shown in FIG. In response to the large depression of the stem (10), the lower end pressing portion (14) of the stem (10) presses the pressed portion (16) of the switching valve (15), so that the switching valve (15) is moved to the valve seat ( 20). Therefore, since the insertion port (8) closed by the switching valve (15) is opened, the aerosol content flowing into the lower chamber (7) is not only the small-volume flow port (17) but also the insertion port. It is introduced into the upper chamber (6) via (8). Therefore, a lot of aerosol contents can be jetted from the upper chamber (6) through the orifice (13). As described above, since a large amount of aerosol contents can be ejected, even a wide space or a large area to be coated can be ejected quickly and efficiently.
[0048]
When the small amount injection or the large amount injection of the aerosol content is completed, the operation lever (33) is returned to the center position of the sliding long hole (32), and the large protrusion (34) is contacted with the lower surface of the push button (24). By combining, the aerosol contents can be prevented from being mistakenly injected and the aerosol product can be safely stored until the next use.
[0049]
Moreover, the formulation example of each content at the time of filling the aerosol container (1) of a present Example with an insecticide and a deodorizer is shown below.

【The invention's effect】
Since the present invention is configured as described above, in an aerosol product capable of switching between a small amount injection and a large amount injection of an aerosol content, the size is changed according to a display opening which is displayed in an easy-to-understand manner. By simply rotating the plate, switching between small injection and large injection can be performed accurately and easily. And the aerosol content can be used efficiently by properly using the spraying form according to the purpose of use, the spraying space and the area of the coating area. In addition, since the large protrusion provided on the rotating plate can be brought into contact with the push button to make it impossible to push down the push button, it is possible to reliably prevent erroneous injection of aerosol contents, and to ensure product safety. The nature will also increase.
