The present invention discloses a cover device used to cover the built-in valve mounting channel port of IBC and a container. The IBC comprises a side plate, a base and a channel located in the base and used to receive the built-in valve. The cover device comprises a cover and structures or components used to detachably connect the cover to the side plate over the channel. The cover can be installed on the base at the position adjacent to the side plate, and can be rotated around a rotational axis of the cover itself, so as to open or cover the channel port. The cover is further provided with a lock hole, and the base is provided with a locking slot, so that the cover can be locked to the base by a disposable lock. The cover device of the present invention has a simple structure and is easy to operate. Further, it can well achieve the effect of dust-proof and/or thief-evident.

The IBC according to claim 1, wherein: said structures on said cover body detachably engaged with said side plate include locking slots located at left and right sides respectively;said mating structure on said side plate includes grooves and ribs on both sides of said grooves respectively; andsaid locking slots are engageable with said ribs under elastic deformation so as to keep said cover on said side plate, and said locking slots are disengageable from said ribs so as to disengage said cover from said side plate. 3. The IBC according to claim 1, wherein: said structures on said cover body detachably engaged with said side plate comprise a locking snap projecting integrally from a surface of said cover body;said corresponding structures on said side plate are a snap hole on said side plate; andsaid locking snap is snappable into said snap hole so as to keep said cover on said side plate, and said locking snap is disengageable from said snap hole so that said cover is disengaged from said side plate. 4. The IBC according to claim 1, wherein: said structures on said cover body detachably engaged with said side plate are a metal piece;said mating structure on said side plate is a magnet; andsaid metal piece and said magnet are attractable to or separable from each other so as to respectively keep said cover on said side plate and disengage said cover from said side plate. 5. The IBC according to claim 1, wherein: a rotating part is provided between said fitting part and said cover body, wherein said fitting part, said rotating part, and said cover body are integrally formed; anda thickness of said rotating part is thinner than that of said fitting part and said cover body, so that said rotating part is used as said rotational axis of said cover and when said cover body is flipped upward, said cover body is rotated around said rotating part. 6. The IBC according to claim 1, wherein said fitting part includes hinge holes, and said cover body includes hinge pins, wherein said hinge holes and said hinge pins constitute hinges so that after said fitting part is assembled to said cover body, when said cover body is flipped upward, said cover body is rotated around said hinges. 7. The IBC according to claim 1, wherein said cover body includes a metal piece at a lower part thereof, and said base includes a magnet, so that said metal piece and said magnet are attractable to or disengageable from each other so as to keep said cover on said base or disengage said cover from said base. 8. An intermediate bulk container (IBC) comprising: a side plate, a base, and a channel located in said base and used to receive a built-in valve, wherein:said IBC further comprises a cover device, and said cover device comprises a cover and structures used to detachably connect said cover to said side plate over said channel;said cover is installable on said base at a position adjacent to said side plate, is rotatable around a rotational axis of said cover, so as to open or cover a channel port of said IBC;wherein said cover is a plate member comprising a fitting part and a cover body, wherein said rotational axis is located between said fitting part and said cover body so that said cover body is rotatable around said rotational axis;fitting pins used to assemble said cover to said base are provided at left and right sides of said fitting part respectively, and grooves for engaging with said fitting pins of said cover are provided at an upper edge of said base of said IBC, whereinsaid fitting pins of said cover are mountable to and removable from said grooves when said side plate is collapsed, and wherein said fitting pins of said cover cannot escape from said grooves when said side plate is erected up; andsaid structures used to be detachably engaged with said side plate are provided on said cover body, and a mating structure corresponding to said structures on said cover body is provided at said side plate; andsaid cover includes a lock hole, and said base includes a locking slot, so that said cover is lockable to said base by a disposable lock. 9. The IBC according to claim 8, wherein said cover body includes a metal piece at a lower part thereof, and said base includes a magnet, so that said metal piece and said magnet are attractable to or disengageable from each other so as to keep said cover on said base or disengage said cover from said base. 10. An intermediate bulk container (IBC), comprising: a side plate, a base, and a channel located in said base and used to receive a built-in valve, wherein:said IBC further comprises a cover device, and said cover device comprises a cover and structures used to detachably connect said cover to said side plate over said channel; andsaid cover is installable on said base at a position adjacent to said side plate and is rotatable around a rotational axis of said cover so as to open or cover a channel port;wherein said cover body includes a metal piece at a lower part thereof, and said base includes a magnet, so that said metal piece and said magnet are attractable to or disengageable from each other so as to keep said cover on said base or disengage said cover from said base,wherein said cover is a plate member comprising a fitting part and a cover body, wherein said rotational axis is located between said fitting part and said cover body so that said cover body is rotatable around said rotational axis;fitting pins used to assemble said cover to said base are provided at left and right sides of said fitting part respectively, andsaid structures used to be detachably engaged with said side plate is provided on said cover body, and a mating structure corresponding to said structures on said cover body is provided at said side plate. 11.
