Embodiments of the present invention are described below with reference to the drawings.

An embodiment of the utility model relates to a collapsible container. As shown in fig. 1, 2, 3, 5, 6, and 7, the foldable container 100 includes: outer container 1 and detachably set up the inner bag 2 in outer container 1, inner bag 2 has opening up's holding opening 20. The outer carton 1 has a base 11, a lid 12 for closing the receiving opening 20 of the sealed inner carton 2, a pair of opposing first side panels 13 and a pair of opposing second side panels 14 foldably connected to the base 11, and the adjacent first side panels 13 and second side panels 14 are connected to surround the base 11, and the lid 12 is hinged to the top end of one of the first side panels 13 by a first hinge 3. A first edge of the box cover 12 is connected with a first side plate 13 through the first hinge 3, a locking hook is further arranged on a second edge of the box cover 12 opposite to the first edge, and a lock matched with the locking hook is further arranged on the other first side plate 13. Each of the first side plate 13 and the second side plate 14 is operable to be turned inside or outside the outer carton 1 relative to the base 11. The flap 12 is operatively reversible to and disposed opposite the outer surface of a first side panel 13 hingedly connected thereto. When the outer box 1 is folded, the first side plates 13, the second side plates 14, and the cover 12 are stacked on the base 11 in a covering manner. The base 11 of the outer box 1 in the folded state is operable to be in stacked abutment with the base 11 of the outer box 1 in the other folded state.

The inner diameter of the top of the inner container 2 is larger than the outer diameter of the bottom of the inner container 2.

Through the above, it is found that, since the inner container 2 and the outer container 1 are detachably connected, and the box cover 12 is hinged to one first side plate 13 and can be turned and folded to the outer surface of the first side plate 13, when the first side plate 13 and the second side plate 14 are folded onto the base 11, the box cover 12 is also folded onto the base 11, thereby realizing the folding of the outer container 1. In addition, the inner diameter of the top of the inner container 2 is larger than the outer diameter of the bottom of the inner container 2, so that a plurality of inner containers 2 can be nested. The foldable container 100 can be separately recycled, the outer box 1 is folded, and the inner container 2 can be overlapped, so that the space is saved, and the transportation cost is reduced.

Further, as shown in fig. 1 and 3, the base 11 has a bottom plate 111, and two pairs of opposite posts 112 and 113 connected to four corner ends of the bottom plate 111, respectively, and the posts may be metal posts. The bottom plate 111 is rectangular, four upright posts are respectively arranged at four corner ends of the rectangle, and each second side plate 14 and each first side plate 13 are respectively clamped between two different upright posts and hinged with two adjacent upright posts. As shown, a first side plate 13 is sandwiched between one upright 112 and one upright 113, and a second side plate 14 is sandwiched between two uprights 112.

As shown in fig. 6, when the outer box 1 is folded, each of the first side plates 13 and each of the second side plates 14 are connected with the corresponding upright column in a bent manner, and the top of the upright column is operatively connected with the bottom of the upright column of the outer box 1 in the rest folded state. Specifically speaking, the bottom of stand is seted up flutedly, and the external diameter at the top of stand is less than the internal diameter of recess, and two outer containers 1 after folding can pile up, and the top of the outer container 1 center pillar that is located the top can insert in the recess of the outer container 1 center pillar that is located the below. In particular, the present invention relates to a method for producing,

further, the upright column 112 and the upright column 113 have the same structure, and the following description will specifically refer to an upright column 112 as an example, as shown in fig. 3, 4 and 5, the upright column has a column body and a support foot 10 with a groove, the column body is vertically connected with the support foot 10, and the first side plate 13 and the second side plate 14 are both connected with the column body in a hinged manner. The top of the upright post 112 is opened with a slot 114 with an upward opening, and the side prism 130 of the first side plate 13 is provided with a protrusion 131 which can be operatively inserted into the slot 114. The upright post is provided with a slide way 115 extending from top to bottom, the side prism 130 of the first side plate 13 can slide along the slide way 115, the clamping groove 114 is arranged at the top of the wall surface of the slide way 115, and the clamping groove 114 is provided with an upward opening. The wall of the slide channel 115 is provided with a long groove 116 extending from top to bottom, and the side prism 132 of the first side plate 13 is provided with an insert 133 capable of sliding along the long groove 116. When the first side plate 13 is erected, the insert 133 is clamped at the bottom of the long groove 116, and the protrusion 131 is inserted into the clamping groove 114. When the first side plate 13 needs to be folded, the lock bolt 6 for locking the first side plate 13 and the second side plate 14 is pulled open, the first side plate 13 is firstly lifted, the embedded part 133 upwards slides in the long groove, the protrusion 131 is separated from the clamping groove 114, and then the first side plate 13 is bent towards the inner side of the outer box 1, so that the first side plate 13 is finally folded. Each second side plate 14 is hinged to the corresponding upright via a hinge shaft 4, and the second side plate 14 is folded toward the base 11 by rotating around the axial direction of the hinge shaft 4. The lower ends of the upright posts 112 and 113 have hinge holes which are closer to the bottom plate 111 than the elongated slots 116, and hinge shafts are connected to the hinge holes. When the outer box 1 is folded, the two second side plates 14 are folded first, and then the two first side plates 13 are folded, so that the second side plates 14 are located below the first side plates 13.

In addition, as shown in fig. 5, the folded first side panel 13 and the folded second side panel 14 are spaced from the vertical columns to form a space 70, which leaves a space for the vertical columns of other outer cases 1. As shown in the figure, the pillar of the upright 112 has a first vertical plate 1121, and a second vertical plate 1122 forming an included angle with the first vertical plate 1121, the bottom of the first vertical plate 1121 and the second vertical plate 1122 is inserted into the supporting leg 10, the bottom of the supporting leg 10 is provided with a groove, the edges of the first vertical plate 1121 and the second vertical plate 1122 connected together form side edges of the upright, a sliding groove is formed between the first vertical plate 1121 and the second vertical plate 1122, one side of the first vertical plate 1121 and the second vertical plate 1122 deviating from each other has an inclined surface, and the two inclined surfaces are gradually far away from the side edges from top to bottom, so that the top sizes of the first vertical plate 1121 and the second vertical plate 1122 are smaller, and the first side plate 13 and the second side plate 14 are far away from, the supporting leg can be inserted into the supporting leg 10 of other outer cases 1, and a space is provided for the supporting leg 10 of other outer cases 1.

As shown in fig. 8, when the outer box 1 is not folded, two outer boxes 1 may be stacked. The outer diameter of the top of the side prism 130 of the first side plate 13 is smaller than the inner diameter of the groove into which the side prism 130 of the first side plate 13 can be inserted. That is, when two outer cases 1 are stacked, the side prism 130 of the first side plate 13 is inserted into the groove at the bottom of the supporting foot 10. It is understood that in other embodiments, a recessed opening may be provided at the top of the side prism of the first side plate 13, and the supporting foot 10 is inserted into the recessed opening when stacking.

The second embodiment of the present invention relates to an outer box of a foldable container 100, which is the outer box 1 of the first embodiment, and is supported by a stopper 139 on the outer surface of a first side plate 13 hinged to a box cover 12, as shown in fig. 3, 4 and 10.
