Abstract: This invention discloses a collapsible container, comprising a base and two pairs of opposite side walls. The side walls are provided with one or more movable portions extending from the bottom of the side walls. The base is provided with one or more opening pockets, wherein the side walls are disposed in the corresponding opening pockets on the base via the movable portions. A hinge device is provided between the movable portions and the opening pockets. The hinge device comprises: hinge holes provided in the movable portions of the side walls; a guiding device provided in the opening pockets of the base; and a connecter provided with hinge pins and a sliding device to be engaged with the guiding device. The sliding device of the connecter is movable up and down in vertical direction along the guiding device in the opening pockets. The hinge pins are disposed in the hinge holes and are rotable around the hinge pins.

Abstract: The present invention discloses an intermediate bulk container (IBC) and a valve opening/closing device therefor. The container comprises a base, side plates, and a valve installed at the bottom of the container. The valve opening/closing device comprises a handle, a motion-transferring device and a valve opening/closing mechanism. The handle is installed at the side plate and is connected with the motion-transferring device. The motion-transferring device is at least partially located in the cavity between two sidewalls of the side plate of the container or at least partially located in the groove provided on the side plate, and is used to transfer the actions acting on the handle to the valve opening/closing mechanism to open/close the valve.

Abstract: A valve core assembly and a valve adopting the valve core assembly. The valve core assembly comprises a valve core (4) and a transmission member (7) having a common axis, and a sliding ejector pin (6) arranged along an axis perpendicular to the common axis. The valve core assembly is disposed inside a valve body (1) and is rotatable about the common axis upon engaging with the valve body (1). The valve core (4) has one concave portion, and the transmission member (7) is at least partially placed inside the concave portion.

Abstract: The present invention discloses a retractable handle assembly, a valve using same and IBC. The retractable handle assembly is used in a valve of IBC. The valve comprises a valve body, a valve core, and a valve stem. The valve stem is used to drive the valve core to move so as to open/close the valve. The handle of the handle assembly is connected to the valve stem and can be rotated around the central rotating axis of the valve stem. When the valve needs to be opened/closed, the handle can be rotated around the central rotating axis to a deployed state to open/close the valve. The handle is rotated around the central rotating axis to a retracted state so as to reduce the space occupied by the valve for the valve to be welded to the liner bag or installed to IBC. In the handle assembly of the present invention, the handle can be switched between a deployed state and a retracted state.

Abstract: The present invention relates to a valve with a hinged valve core. The valve comprises a valve body, a valve core, an operating mechanism, a motion-transferring device and a locking device. The valve body is a housing. The housing is formed with a operating hole used to partially accommodate the operating mechanism and a channel having an inlet and an outlet. The valve core is connected with the valve body through a hinge. The operating mechanism is used to operate the valve core to be rotated around the central axis of the hinge to open/close the valve. The motion-transferring device is used to transfer actions on the operating mechanism to the valve core, and when the valve is closed or open, the valve core is locked on the valve body through the locking device. The valve of the present invention has a compact structure, is easy to operate, requires a small torque for opening and allows a large flow when opened.

Abstract: A lid hanging structure of a container is disclosed in the present invention. The container includes a base, side plates and a lid. the hanging structure includes hanging members and hanging slots, wherein the hanging members are engaged or disengaged with the hanging slots respectively so as to hang the lid on the container or remove the lid from the container, and one of the anging members and the hanging slot is provided on the lid and the other is provided on the side plates. According to the lid hanging structure, it is convenient to remove the lid from the container when necessary. That is to say that, the lid can be removed directly when not in use or in the hanging state, and can be removed by simple operation in the hanging state, so as to reduce the amount of labor, and the structure is simple and the cost is low.

Abstract: The present invention discloses an intermediate bulk container and a valve opening/closing device therefor. The container comprises a base, side plates, and a valve installed at the bottom of the container. The valve opening/closing device comprises a handle, a motion-transferring device, a valve opening/closing mechanism and a clutch device. The handle is installed on the side plate and is connected to the motion-transferring device. The motion-transferring device is used to transfer the actions acting on the handle to the valve opening/closing mechanism so as to achieve opening/closing of the valve. The clutch device is used to engage the motion-transferring device with the valve opening/closing mechanism or disengage the motion-transferring device from the valve opening/closing mechanism.

Abstract: The present invention discloses a valve opening/closing device for an intermediate bulk container. the container comprises a base, side plates, and a valve provided on the base. Wherein the valve opening/closing device comprises a handle, a motion-transferring device, and a valve opening/closing mechanism, wherein the handle is mounted on the side plate and connected to the motion-transferring device, and the motion-transferring device is used to transfer the force applied on the handle to the valve, so as to open or close the valve. For the valve opening/closing device of the present invention, the operating handle is provided at an appropriate position at the side plate of the container, thereby avoiding bending over or squatting on the ground, etc when opening or closing the valve, facilitating use. In addition, the operating moment can be adjusted through adjusting the transmission ratio of the motion-transferring device, which makes it easy to control the operating force.
