A sealed container that enables safe and smooth exchange while preventing backflow of the fluid substance once taken out from the above route when replacing the sealed container with a new sealed container upon completion of removal. The present invention relates to a contents removal device.

[Conventional technology]

Japanese Patent Application Laid-Open No. 1983-1983 as a conventional container contents removal device
There is an invention disclosed in No. 13396.

The discharge valve of the present invention includes an inner cylinder having a blade fixed to one end thereof, which cuts a seal plug that closes a liquid outlet nozzle provided at the lower part of a liquid container on the circumference, leaving a part when discharging, and the inner cylinder. It consists of an outer cylinder into which a cylinder is inserted and the inner cylinder is rotated by a screw to move it back and forth, and when discharging, the blade cuts the seal plug circumferentially through the socket, releasing the liquid in the liquid container to the outside. This means that the waste is discharged. The outer cylinder has a liquid outlet for discharging liquid, and a gasket is provided on the outer peripheral surface of the inner cylinder to adjust the amount of liquid discharged after the seal plug is opened.
It also plays the role of blocking the liquid outlet and preventing the backflow of liquid once discharged from the liquid outlet.

[Problem to be solved by the invention]

However, in the above-mentioned conventional technology, since a blade fixed to the end of the inner cylinder cuts the seal plug circumferentially, when the seal plug is cut to a certain extent (for example, about 1/2 of the circumference), The liquid leaks to the head of the cylinder, and the liquid pressure prevents the inner cylinder from moving forward, making it difficult to break the seal evenly. However, when the amount of liquid discharged increases rapidly due to operation of the discharge valve, there is a problem that there is a risk that the incised portion may peel off and enter the discharge path.

On the other hand, in this conventional technology, when attaching a discharge valve to a new liquid container, the inner cylinder is moved back and the blade is retracted, so there is a problem that the liquid remaining in the discharge path flows backward from the liquid outlet and comes into contact with the outside air. It was hot.

On the other hand, it is necessary to use a sharp blade to cut the seal, and it is not safe to handle.

[Means to solve the problem]

The present invention has been made in view of the above, and it is possible to discharge a fluid substance from a closed container (liquid container) in a state where it is sealed from the outside air, and to facilitate the discharge operation.
For safety, the container is sealed with an outlet sealed with a seal that is provided at the bottom of a closed container housing a fluid substance that is likely to deteriorate in quality due to contact with the outside air, and the fluid substance is discharged to the outside. a cylindrical body provided with an outlet for discharging; a means inserted into the main body for breaking the seal; and a cylindrical body attached to the breaking means for discharging the air from the outlet when the seal is broken; and a valve body for adjusting the flow rate of the fluid substance to be removed and for closing the outlet when exchanging it with another sealed container, wherein the means for breaking the hermetic seal is provided in the main body. A rod-shaped body disposed on a central axis in the longitudinal direction and having a pointed head, which pierces the seal by movement along the central axis to form a liquid passage hole on the seal, and Contents of a sealed container, characterized in that the head is in a position where the head does not protrude from the end of the main body when the valve body closes the outlet and does not pierce the seal when the sealed container and the main body are engaged. A take-out device is provided.

[Effect]
