Description

  The present invention relates to a plug used for a sealed container into which a fluid is injected or sucked, such as a floating bag, a cushioning material, a liquid container, an air jack, and a compressed futon bag, a sealed container using the plug, and the The present invention relates to an injection device used for a stopper.

  Conventionally, air is injected into the interior such as a float bag, cushioning material, air jack, etc., liquid is injected into the interior such as a beverage container, or the interior air is aspirated like a compression futon bag. Various sealed containers, such as those, into which fluid is injected or sucked are known.

  When injecting or aspirating fluid into these sealed containers, the fluid is injected or aspirated from the through hole formed in the sealed container, and then the through hole is plugged. Various types are known.

  For example, as an air stopper, an air stopper 10 is used to inject air into an air bag such as a floating ring, a pillow, or a bed that is formed into a bag shape having an air chamber 22 by a soft synthetic resin sheet 21. It is provided with a flexible support portion 11a integrally having a plug 13 that closes the air hole 12, and is attached to the surface of the synthetic resin sheet 21, and on the back surface of the attachment base 11. A housing portion 14 having a plurality of air holes that are integrated to allow air from the air holes to enter and exit the air bag, and a part of the side wall of the housing portion 14 projects inward. The thing provided with the latching | locking part 16 formed by this and the sponge body 17 accommodated in the accommodating part 14 inside this latching | locking part 16 is known (refer patent document 1).

  Also, as a beverage container plug, a pivoting portion 26a is provided at one end of the operation lever 26, a pressing portion 26b is provided at the other end, and a slide member 30 urged to the other end side by a spring member 31 is mounted at the intermediate portion. The hook-shaped engagement portion 30 a is formed on the lower surface of the slide member 30. The pivoting portion 26 a is supported by the stopper body 22 so as to be rotatable and slidable, and an engaging projection 33 c is provided at the tip of the valve rod 33. When the stopper 20 is removed from the container body 10 and the operation lever 26 is rotated more than the rotation limit L1 and is slid to one end side, the slide member 30 is moved to one end side of the operation lever 26, and the engagement protrusion 33c. Is disengaged from the engaging portion 30a, and the valve mechanism 23 is disengaged from the plug body 22. When the stopper 20 is mounted on the container body 10, it is known that the handle 14c restricts the rotation of the operation lever 26, and the engaging protrusion 33c holds the state accommodated in the engaging portion 30a ( Patent Document 2).

  Similarly, as a plug for a beverage container, a valve rod having a liquid passage 10 having an inlet 6 and an outlet 9 in the stopper body 2 and having a water stop valve 11 for opening and closing the inlet 6 at the lower end. 12, the valve member 12 is always urged upward, the spring member 15 is closed to close the water stop valve body 11, and the operation member 3 is rotatably provided on the top of the plug body 2. A pressure reducing port 8 that urges the valve rod 12 downward by turning the member 3 to open the water stop valve body 11, communicates with the inside of the beverage container and the inside of the stopper body 2, and depressurizes the inside of the beverage container; A pressure reducing valve body 16 that opens and closes the pressure reducing port 8 and a small-diameter spring member 20 that normally closes the pressure reducing valve body 16 are provided. It is known that the operation member 3 opens the pressure reducing valve body 16 before the water stop valve body 11 is opened by the rotation of the operation member 3 (see Patent Document 3).
