Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

Hereinafter, the same reference numerals will be used to denote the same constituent elements in addition to the reference numerals even if they are shown in other drawings.

A shopping bag 100 according to a preferred embodiment of the present invention includes a bottom plate 110, a front plate 120, a rear plate 130, side plates 140a and 140b, and a wing 150. [

The bottom plate 110 constitutes the bottom surface of the shopping bag 100 and is provided in a rectangular plate shape having four ridges 111, 112, 113 and 114.

A front plate 120 and a rear plate 130 of a rectangular plate shape having a predetermined area are connected to the first and second edges 111 and 112 of the four edges 111, 112, 113 and 114, respectively. Accordingly, the front plate 120 and the rear plate 130 are connected to the bottom plate 110 so as to be able to be folded with respect to the first frame 111 and the second frame 112, respectively.

The third rim 113 and the fourth rim 114 connecting the first rim 111 and the second rim 112 of the four rims 111, 112, 113 and 114, respectively, The first and second ridges 150 and 150 are connected to the bottom plate 110 so as to be able to be connected to each other with the boundary between the third rim 113 and the fourth rim 114.

The front plate 120 and the rear plate 130 which are connected to the first rim 111 and the second rim 112 of the bottom plate 110 and opposed to each other have a pair of side plates 140a, Respectively.

Accordingly, the shopping bag 100 according to the present invention can be easily removed from the shopping bag 100 surrounded by the front plate 120, the rear plate 130, the pair of side plates 140a and 140b, and the bottom plate 110, Thereby forming an inner space having an open upper portion so as to be embedded therein. At this time, the lower ends of the pair of side plates 140a and 140b are positioned on the third rim 113 and the fourth rim 114.

Here, the bottom plate 110 may be provided with a separate floor folding line 115 formed therein so as to be parallel to the first and second edges 111 and 112. When the shopping bag 100 is not used, the bottom folding line 115 overlaps the two portions of the bottom plate 110 divided by the bottom folding line 115 through the bottom folding line 115, The front plate 120 and the back plate 130 connected to the plate 110 are overlapped with each other to reduce the total volume of the shopping bag 100.

The pair of side plates 140a and 140b may have an auxiliary wing portion 151 having a shape corresponding to the wing portion 150 at the lower end of the pair of side plates 140a and 140b, Lt; / RTI > The other end of the auxiliary wing 151 is connected to the wing 150 by a wing fold line 152. Accordingly, when the wing 150 and the auxiliary wing 151 are folded with the wing fold line 152 as a boundary, the wing 150 and the auxiliary wing 151 are overlapped with each other, When the first and second wings 150 and 151 are folded upward at the boundary between the third and fourth edges 113 and 114 of the bottom plate 110 and the lower ends of the side plates 140a and 140b, Respectively, to the side plates 140a and 140b. In order to fix the wings 150 and the auxiliary wings 151 to the side plates 140a and 140b, the fixing portions 145 and the fixing portions 153 corresponding to the side plates 140a and 140b and the wings 150a and 140b, (150). That is, the side plates 140a and 140b are provided at one end thereof with a fixing portion 145 having a head portion 145a having a relatively larger cross-sectional area than the middle portion, The wing portion 151 is provided with a slit groove 153 having a predetermined length to allow the head portion 145a to pass therethrough. The wings 150 and the auxiliary wings 151 are overlapped with each other via the wing fold lines 152 and the third and fourth rims 113 and 114 of the bottom plate 110 and the side plates 140a 140b are fixed to the side plates 140a, 140b by being passed through the head portion 145a of the fixing portion to the slit grooves 153 after being folded upward by the lower ends of the side plates 140a, 140b. Because the lower ends of the side plates 140a and 140b are kept in contact with the third rim 113 and the fourth rim 114 of the bottom plate 110, The lower end of the side plates 140a and 140b is prevented from being separated from the third rim 113 and the fourth rim 114 due to the weight of the article so that the overall shape of the shopping bag 100 can be maintained.

On the other hand, the pair of side plates 140a and 140b are provided with partitioning lines 142 dividing an area inside the height direction into two areas, a first area 141a and a second area 141b. Accordingly, when the first area 141a and the second area 141b are folded by the boundary of the partition line 142, the shopping bag 100 according to the present invention can be used as a general shopping cart having a wide upper part and a narrow lower part. . As a result, as the area of the open top portion becomes wider, it becomes possible to easily store the article having a larger area. At this time, a pair of lower folding lines 143 connected to the lower vertexes P of the side plates 140a and 140b are symmetrically provided at the lower side of the partitioning line 142 with the boundary of the partitioning lines 142 . Accordingly, when the first area 141a and the second area 141b are folded at a predetermined angle through the partition line 142, the wings 150 fixed to the side plates 140a, The lower fold line 143 can maintain a flat state.

A pair of upper folding lines 144 formed at an upper side of the partitioning line 142 at an angle inclined toward both side edges of the side plates 140a and 140b are symmetrical with respect to the partitioning line 142 . The upper fold line 144 may extend to the upper end of the front plate 120 and the upper plate 130. Accordingly, when the upper side of the side plates 140a and 140b is pushed into the inner space side via the upper folding line 144, the shopping bag 100 according to the present invention changes its shape into an approximately octagonal shape, The shape of the shopping bag 100 can be changed. When the shape of the shopping bag 100 is changed to an octagonal shape as described above, the area of the opened upper portion is reduced, thereby preventing the articles contained in the shopping bag 100 from being exposed to the outside during the movement process.

The partition line 142 is divided into a first area 141a partitioned by the partition line 142 and a second area 141a partitioned by the partition line 142 when the shopping bag 100 is not used as in the floor fold line 115 formed on the bottom plate 110. [ The folding line 141b is folded over the partition line 142 and overlapped with each other to form a folding line for reducing the total volume of the shopping bag 100. [

On the upper side of the front plate 120 and the rear plate 130, a pair of knobs 160 are provided at positions corresponding to each other so that the user can easily mount the shopping bag 100.

As described above, the shopping bag 100 according to the present invention can be changed into the shopping bag 100 having various shapes through the folding process using the partition line 142, the upper fold line 144 and the lower fold line 143, So that it can be suitably changed according to the taste or use state of the user.
