ある。Detailed Description of the Invention [Field of Application and Summary of the Invention] The present invention relates to a valve device used in an aerosol container, etc., and a method of filling contents into a sealed container using this valve device. When filling containers with contents such as liquid drugs or propellant gas using the pressure filling method,
By making it possible to widen the opening of the valve device during filling,
It is possible to shorten the time for filling the contents, and for this purpose, the valve device that opens when filling the contents is provided separately from the valve device that opens when the contents are injected.
［従来技術及びその課題］

には大掛りな充填装置を使用しなければならない。The latter under-cup method has the advantage that since the container is filled with the lid of the sealed container removed, the opening for filling is large and the injection gas etc. can be filled at high speed. However,
In this method, it is necessary to seal the mouth of the container with a lid equipped with a valve device immediately after filling is completed, and for this purpose, a large-scale filling device must be used.

した構成である。As shown in the figure, a conventional valve device has an annular ring made of an elastic material attached to an upper end flange (13) of a cylindrical portion (12) of a lid (11) that closes the mouth of a container (1). Valve body (21)
and the upper end flange (13).

The inner peripheral edge of the annular valve body (21) is fitted into an annular groove (24) formed in the middle outer periphery of the shaft body (23). . And the shaft body (
A hollow chamber (25) that is open only at the protruding end of the groove (23) communicates with the annular groove (24) via a through hole (2B) (26).

1) is elastically deformed to form the through hole (26) and the annular valve body (21).
A gap is created between the inner peripheral surface of the container (1) and the hollow chamber (25) in this state.

The injection gas, etc. is
26) and between the shaft body (23) and the cylinder part (12) V4 (G
)”Injection gas etc. will be filled into the container (1) along the route of the middle casing (22)=>container (1). However, in this gas filling path, especially the annular valve body (21)
The cross-sectional area of the flow path near the inner peripheral edge cannot be set to a sufficient size due to the dimensional and structural constraints of the lid (11) and the cylindrical portion (12). It takes a long time to fill. On the other hand, the gap (G) is also set to be extremely small due to the above reasons as well as the requirement for stability in the vertical movement of the shaft body (23), and the cross-sectional area of the flow path for filling the contents when the valve device is opened is set to be very small. becomes extremely small. As a result, the workability of this gas filling operation is extremely inferior to that of the under-cup method.

(12) or the inner peripheral edge of the annular valve body (21) tightly attached to the casing (22) is fitted into the annular groove (24) formed in the middle of the outer circumference of the cylinder shaft (20). ) is made of an elastic material, and a through hole (26) passing through the inner peripheral side of the cylinder shaft (20) is formed in the annular groove (24), so that the container (
1) A lift valve (3) that closes the inner end is provided, and the valve shaft (31) of the lift valve (3) is loosely fitted through the inside of the cylinder shaft (20) to open the container of the cylinder shaft (20). The lift valve (3) is urged in the valve closing direction by protruding from the outer end.
［作用］ 本発明の上記技術的手段は次のように作用する。[Effect] The above technical means of the present invention operates as follows.
リフト弁（３）は筒軸（２０）の容器内端部に対接し、
このリフト弁（３）は常時閉弁方向に付勢されている。The lift valve (3) is in contact with the inner end of the container of the cylinder shaft (20),
This lift valve (3) is always biased in the valve closing direction.
従って、筒軸（２０）も突出方向に付勢されており、環
状弁体（２１）の内周端面ば環状溝（２４）の底壁に対
接して貫通孔（２６）を閉塞する。Therefore, the cylindrical shaft (20) is also urged in the protruding direction, and the inner peripheral end surface of the annular valve body (21) comes into contact with the bottom wall of the annular groove (24) and closes the through hole (26).
これにより、自由状態では、バルブ装置は閉弁状態とな

してその内周端面が貫通孔（２６）を閉塞する。When the cylinder shaft (20) is pushed in from this state, the annular valve body (21
) is curved at its inner peripheral edge side as in the conventional one, and the circuit of the through hole (26) is opened. Therefore, if a push button is attached to the cylinder shaft (20) in the same manner as the valve device described above, the valve device can be opened by operating the push button. Furthermore, when the operating force is released, since the lift valve (3) is always biased in the valve closing direction, the cylindrical shaft (20) that is in contact with it is also biased in the protruding direction, and the annular valve body (21 ) is restored to its initial state and its inner peripheral end surface closes the through hole (26).

が容器（１）内に充填されることとなる。In order to fill the contents into the container (1) through the valve device, the valve stem (31) is pushed in relative to the cylinder axis (20), and the cylinder axis (20) is pushed in. The cylinder is pushed in a fixed stroke to open the annular valve body (21) and the lift valve (3), and the contents are directly filled into the container (1) through the inside of the cylinder shaft (20). At this time, since the valve stem (31) and the annular valve body (21) are loosely fitted, the through hole (26)
Since the circuit through the container (1) is also open, the contents are filled into the container (1) with a sufficient cross-sectional area of the flow path as a circuit for filling the contents.
