In this case, since the elastic valve body 113 moves in the axial direction according to the axial movement of the shaft 114 by rotating the handle 108, the flow rate of the contents 2 can be adjusted arbitrarily, and the flow rate of the contents 2 from the closed container 1 can be adjusted. The extraction can be stopped and started as desired in a state where it is cut off from the outside air.

[Problem that the invention seeks to solve]

However, in the case of this device for taking out the contents of a closed container, there are problems such as breakage of the thin film seal, supply of contents, etc.
Since the exact amount of movement of the handle required to perform each operation of disconnecting the suction tube from the inside of the main body cannot be confirmed from the outside of the device, there is a risk of seal breakage,
If the contents cannot be supplied or the connection between the suction tube and the main unit cannot be accurately disconnected, for example, when the flexible airtight container is used up and replaced with a new flexible airtight container, the contents remaining in the suction tube may leak through the left end opening. There was a risk that the cutter would accidentally break the seal of the new container when the main body was screwed into the new container.

[Means and actions for solving problems]

The present invention has been made in view of the above, and is capable of reliably performing the operations of breaking the seal, supplying the contents, and cutting off the connection between the suction tube and the inside of the main body, and is capable of providing a new By reliably preventing liquid leakage from the sealed container and external leakage (backflow) of the contents remaining in the suction tube, we can always supply fluid substances such as liquids, viscous substances, and powders of stable quality as needed. In order to smoothly supply the fluid substance, a closed container contents extraction device seals an outlet of the fluid substance with a seal and breaks the seal to take out the fluid substance from a bag-like container containing the fluid substance. a tubular body having an outlet at a predetermined position, one end of which is engageable with the outlet and which discharges the extracted flowable substance in the supply direction; a rupturing member that ruptures the hermetic seal with a rupture; a valve member that moves in the axial direction of the tubular body in conjunction with the rupturing member to open or close the discharge port; the rupturing member and the valve member; an operating member that operates the movement of the tubular body from the outside by displacing the tubular body in at least an axial direction; and an indicating means for instructing the amount of displacement of the operating member onto the tubular body, wherein the tip of the breaking member does not protrude from the end of the tubular body when the valve member closes the outlet and the distal end of the breaking member The present invention provides a device for removing the contents of a closed container that is located in a position that does not pierce the seal when the outlet and the tubular body are engaged with each other.
