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. When folded, the side walls of the collapsible container according to this invention will not inclined relative to the base. In addition, the collapsible container of the invention can be detached or folded in any consequences without tool.

1. A collapsible container, comprising a base and two pairs of opposite side walls, wherein: each of the side walls is provided with one or more movable portions extending from a bottom of the side walls, and the base is provided with one or more opening pockets, wherein the side walls are positioned in corresponding opening pockets on the base via the movable portions;a hinge device is provided between the movable portions and the opening pockets, wherein 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; wherein,the connecter is movable up and down in a vertical direction along the guiding device in the opening pockets via the sliding device, and the hinge pins are disposed in the hinge holes and enable the side walls to be rotated around the hinge pins. 2. The collapsible container according to claim 1, wherein an interlocking device is disposed between at least one side wall and the base, so that the interlocking device prevents the side wall from moving in vertical direction relative to the base when the side wall is in erected status relative to the base, and the interlocking device between the side wall and the base is releasable through the rotation of the side wall around the hinge pins. 3. The collapsible container according to claim 1, wherein the sliding device on the connecter is a through hole in the center thereof; the hinge pins are located perpendicular to an axis of the through hole on one or two sides of the connecter; and the guiding device in the opening pockets of the base is a vertical cylinder capable of passing through the through hole, so that the connecter is movable along an axis of a cylinder. 4. The collapsible container according to claim 1, wherein the sliding device on the connecter is a straight wall disposed on one end of the connecter; the hinge pins are located at an other end of the connecter and perpendicular to the straight wall; and the guiding device in the opening pocket is a straight slot perpendicular to a plane of the base, wherein the straight wall is slidable along the straight slot, so that the connecter is movable along the straight slot. 5. The collapsible container according to claim 1, wherein the opening pockets in the base are provided with lateral shoulders with a lateral distance H2 from an end surface thereof to an axis of the hinge pins; wherein a distance from an external edge of the movable portion of the side walls disposed in the opening pocket to the axis of the hinge pin is larger than H2. 6. The collapsible container according to claim 1, wherein the movable portion is provided with a recess at a lower portion thereof; the hinge hole is an arc profile disposed at a root of the recess; and a narrowed segment is provided between the arc profile and an opening of the recess, so as to prevent the hinge pins from easily dropping off after entering into the recess. 7. The collapsible container according to claim 2, wherein the interlocking device comprises ledges provided on the two sides of the movable portion and grooves on the base for engaging with the ledges, so as to restrict a movement of the side wall in vertical direction relative to the base when the side wall is in erected status. 8. The collapsible container according to claim 1, wherein the movable portion is provided with an inclined ramp, when connected, a vertical distance from the ramp to an axis of the hinge pins of the connecter is no greater than a vertical distance H2 from the axis of the hinge pin to an end surface of a shoulder on the base. 9. The collapsible container according to claim 1, wherein the movable portion is provided with a slot at a bottom end on one side thereof, and the base is provided with a baffle, wherein the slot allows the baffle of the base to be received therein when the side walls are erected, so as to restrict the side walls from moving inwardly when suffering external force.
