Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an aerosol container filled with contents such as pesticides, cosmetics, pharmaceuticals, etc., and facilitates the discharge of the propellant remaining in the aerosol container after the use of the contents is completed. , A dual aerosol container.

[0002]

[Prior art]

 Conventionally, an aerosol container is configured such that the propellant and the content are directly filled in the aerosol container and the content is ejected to the outside by the pressure of the propellant while the propellant and the content are in contact with each other. There are aerosol devices.

Further, as another mechanism, an inner bag is installed in an aerosol container, the contents for injection are filled in the inner bag, and a propellant is filled between the inner bag and the inside of the aerosol container. There are some that consist of double containers. Then, by pressing the inner bag from the outer surface with a propellant, the contents in the inner bag are sprayed to the outside through the stem.

In an aerosol container that does not form an inner bag, the propellant after use can be discharged relatively easily by making a hole in the aerosol container or continuously pressing the stem for a certain period of time. It is possible to discharge the propellant to the outside.

However, in the case where the inner bag is formed in the aerosol container, even after the injection of the content is completed, the propellant remains in the aerosol container in the same amount as that at the beginning of the filling without being consumed at all. For this reason, if an action such as making a hole from the outside of the container is performed, high-pressure propellant is injected outside, which is dangerous. Further, no matter how much the stem is pressed, the inside of the inner bag, which communicates with the stem, and the filling portion of the propellant are separated by the inner bag, so that the propellant cannot be discharged to the outside.

Then, there is a device described in Japanese Utility Model Publication No. 1-167365 for the purpose of discharging the propellant in such a double container.

In this invention, after the injection of the contents of the inner bag is completed, the needle-like protrusion that is activated by the pressing of the stem is pushed down, and the inner bag is pierced by the needle-like tip portion to destroy the inner bag. By doing so, the propellant is communicated with the inner bag, and the propellant is discharged to the outside.

Further, as in the invention described in Japanese Patent Application Laid-Open No. 2-218462, after the injection of the contents of the inner bag is completed, a thin rod or the like is inserted from the upper part of the mountain cup to deform the gasket inside, and thus the propellant is injected. There are those that are designed to discharge.

[0009]

[Problems to be Solved by the Invention]

 However, in the device disclosed in Japanese Utility Model Laid-Open No. 167365/1989, the inner bag is formed of a thin soft material so that it can be easily deformed. The bag is deformed and cannot be easily destroyed. Moreover, it is difficult to confirm this destruction from the outside. Therefore, if the aerosol container is discarded while misidentifying that the inner bag has been destroyed, there is a high possibility of causing an accident such as an explosion.

Further, in the invention described in Japanese Patent Application Laid-Open No. 2-218462, the gasket must be continuously pressed by a rod or the like until the discharge of the propellant is completed, which is extremely large for a person who performs the propellant discharge work. It is burdensome and not practical.

The present invention intends to make it possible to discharge the propellant filled in the aerosol container very easily by one operation.

[0012]

[Means for Solving the Problems]

 In order to solve the problems described above, the present invention mounts an inner bag filled with contents in an aerosol container, connects the inside of the inner bag and the stem of an aerosol valve, and at the same time, the outer surface of the inner bag and the inside of the aerosol container. In the case where the inner bag is pressed by the propellant filled in the space between and, and the contents in the inner bag can be sprayed to the outside via the stem, the stem is urged toward the outside of the aerosol container. The seat of the ridge is located so as to face the lower surface of the stem, and the seat is projected to the inner surface of the housing through the breakable hinge part, and the exhaust recess is formed on the outer surface of the housing corresponding to this hinge part. However, the inside of the housing and the inside of the aerosol container can be communicated with each other at the time of cutting the hinge portion through the exhaust recess.

[0013]

[Action]

 Since the present invention is configured as described above, when a normal content is to be jetted, the stem is pressed via a push button or the like. By this pressing, the aerosol valve is opened, and the contents in the inner bag, which are constantly pressed by the propellant in the aerosol container, can be ejected to the outside via the aerosol valve.

After the injection of the content is completed and the content in the inner bag is ejected to the outside, the propellant is discarded. To dispose of the propellant, the head of the stem protruding from the aerosol container to the outside is strongly hit with a hammer or the like. Due to this impact, the stem descends rapidly into the housing and strongly strikes the seat of the bar positioned facing the lower surface of the stem.

Since this seat is connected to the inner surface of the housing via a breakable hinge part, the lower end of the stem hits this hinge part to break the seat and drop it into the inner bag. . Due to this drop, the spring loses the pressing force, so that the stem is kept inserted in the housing. Then, the aerosol valve is opened in this state.

When the seat is dropped from the hinge part by the impact of the hinge part with the stem, the exhaust recess formed on the outer surface of the housing is opened, and the inside of the housing communicates with the inside of the aerosol container. Becomes Therefore, the propellant remaining inside the aerosol container is discharged to the outside through the valve mechanism that opens from this exhaust recess.

Therefore, the discharge of the propellant cannot be confirmed as in the conventional case, and if the stem is inserted into the housing without being restored by the impact of the stem, the hinge portion must be destroyed. Therefore, the propellant is reliably discharged from the exhaust recess. Moreover, since the stem is inserted into the housing by a single impact, no continuous pressing is required, and the propellant can be discharged very easily.

[0018]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. (1) is an aerosol container having a mountain cup (2) fixed to the upper end thereof and a gasket (3) provided on the inner surface of the mountain cup (2). The housing (4) is fixed via the. An inner bag (5) made of a soft elastic film or the like is connected to the lower end of the housing (4), and the inner bag (5) is filled with the content for injection.

Further, the stem (6) is inserted into the housing (4), and the upper end of the stem (6) is projected outward through the gasket (3). The stem (6) is pressed and urged outward by the spring (7), and the orifice (8) provided on the side surface is normally sealed by the inner peripheral end surface of the gasket (3). .

The spring (7) that pushes the stem (6) outward is connected to the stem (6) at the upper end and pushes the lower end against the seat (10) to push the stem (6) outward. It is pressing and urging. The seat (10) is fixedly formed on the inner surface of the housing (4) via a hinge (11).

The hinge portion (11) is formed to be thin so that it can be broken by hitting or the like, and is formed into two U-shapes at the top and bottom, and at the formation interval of the two hinge portions (11), The exhaust recess (12) is formed from the outside of the housing (4). The exhaust recess (12) is formed so that the inside of the aerosol container (1) and the inside of the housing (4) do not always communicate with each other, but the exhaust recess (12) is exposed to the lower surface of the stem (6) so as to face the housing (4). It is formed by projecting inward.

In the structure configured as described above, when the normal ejection of the contents is to be performed, the stem (6) is pushed through the push button (13) fixed to the upper end of the stem (6). Press. By this pressing, the stem (6) is pushed down into the housing (4) against the restoring force of the spring (7), and the orifice (8) is released from the sealing of the gasket (3). The contents in the inner bag (5), which is pressurized by the propellant in (), can be sprayed to the outside.

In this case, since the stem (6) is only manually pressed normally, the hinge part (11) is not destroyed, and the stem (6) functions as an ordinary aerosol valve. It is possible to spray the contents. In addition, in order to prevent the stem (6) from being pressed too much by mistake, the distance between the lower end of the push button (13) fixed to the upper end of the stem (6) and the upper end surface of the mountain cup (2) should be set to By forming the stem (6) shorter than the interval until it contacts the hinge (11), the stem (6) can be prevented from coming into contact with the hinge (11) by pressing. .

After the injection of the contents in the inner bag (5) is completed, the push button (13) is removed from the stem (6) and the upper end of the stem (6) is hit hard with a hammer or the like. By this striking, the seat (10) desired to be located at the lower end of the stem (6) is strongly striking by the stem (6), and the hinge part (11) is separated from the inner surface of the housing (4). Fall inside the bag (5).

When the seat (10) is dropped, the exhaust recess (12) acts as a communication hole, and communicates the inside of the aerosol container (1) with the inside of the housing (4). The propellant located inside 1) is discharged to the outside via the stem (6). Further, the stem (6) is released from the upward biasing by the spring (7) due to the breakage of the seat (10), so that the state of being pushed into the housing (4) continues, The fiss (8) remains released from the gasket (3).

Therefore, the ejection of the propellant can be performed by only one operation of striking the stem (6), and the ejection of the propellant can be surely performed by an extremely simple method.

[0027]

[Effect of device]

 As described above, the present invention can very easily discharge the propellant in the double aerosol container provided with the inner bag. In addition, the discharge of the propellant can be easily confirmed from the outside by keeping the insertion state of the stem into the housing, and it can be mistakenly discarded that the discharge has been completed, resulting in an explosion accident. There is no danger of it occurring.

Further, since the discharge of the propellant is completed by one operation by striking the stem with a hammer or the like, it is not necessary to perform a constant operation for a long time, and it is possible to discharge the propellant very easily. To do.
