A fluid coupling includes a body, a poppet valve assembly, a handle shaft assembly, and a retention member. The body has a fluid conduit, a through-hole extending through a sidewall, and one or more openings that extend between an external surface of the body and an interior of the through hole. The poppet valve assembly is disposed within the fluid conduit and is selectively movable between an open position and a closed position. The handle shaft assembly extends through the through-hole and into the fluid conduit and is interconnected with the poppet valve assembly such that the handle shaft assembly can be actuated to move the poppet valve assembly between the open position and the closed position. The retention member is insertable through the one or more openings and into the through-hole to interact with the handle shaft assembly to selectively hold the handle shaft assembly in the body.

A container comprises a base, side panels and a cover. The side panels are connected to the base. The cover is locked onto the tops of the side panels through a locking device. The locking device comprises automatic locks and manual locks. The automatic locks are arranged on two opposite sides of the cover, and the manual locks are arranged on the other two sides of the cover. The automatic locks and the manual locks are both adopted on the cover and used in cooperation with a tilting-prevention device, thus the container has the tilting-prevention effect, the stacking and supporting effect, and the locking and unlocking guiding and return guiding effect. The locking strength is increased, and the convenience in locking operation and unlocking operation is improved.

A raw material feed hopper according to the present embodiment may include a hollow tube having a raw material accommodating space formed therein, a supporter supporting the hollow tube, a cone accommodated in the raw material accommodating space so as to be able to lift up and down, a rod connected to the cone, a connector connected to an upper portion of the rod, a lifting rod connected to the connector, and an elevator installed on the supporter for lifting up and down the lifting rod.

A charging port 5 in an upper part is covered in an openable and closeable manner with a lid body 6 of a sliding door type (sliding type) that reciprocates horizontally. The lid body 6 reciprocates in conjunction with a movement of an operation member 50 provided in a side part of a container vessel 3 or at a location close to the side part. It is preferable that the charging port 5 includes an opening that is long along a length direction of the container vessel 3, and the lid body 6 reciprocates horizontally in a width direction of the container vessel 3 to open and close the charging port 5.
