Abstract
Description
- Not applicable.
- Not applicable.

- Not applicable.
- The present invention relates generally to a folding box and, more particularly, to a folding box which has a space for storing items therein and which can be folded and unfolded to minimize volume of the folding box.
- Generally, boxes, which are made of synthetic resin and required to be cushioned, lightweight, and impact resistant, are mainly used to transport or store items repeatedly without separate cushioning materials and each have an inside space for storing the items.
- Such a storage box requires a storage space equal to volume of the storage box, when the storage box stores the items therein.
- However, in the case of an empty box, a space for storing the empty box without the items to be stored is needed, so the space is wasted for storing the empty box, and portability of the box is reduced, which cause a problem of inconvenience.
- Here, there is Korean Patent No. 10-1179611 entitled “Packing box of foldable foam plastic”. In this case, when a packing box is stored or carried without the items to be stored therein, a method of folding a box body by pressing a folding part provided on the box body from outside to inside after separating an upper cover and a lower cover from the box body is disclosed.
- However, in order to fold the box body, the upper cover and the lower cover should be separated from the box body in advance, thus the packing box is inconvenient to use.
- In addition, another example is disclosed in Korean Patent Application Publication No. 10-2015-0011668 entitled “Folding type packing box”. In this case, when a packing box is stored or carried without storing the items inside the packing box, volume of the box is reduced by only folding side parts sequentially toward a bottom part in a state of opening an upper covering member, which causes a problem of inconvenience.
- The foregoing is intended merely to aid in the understanding of the background of the present invention, and is not intended to mean that the present invention falls within the purview of the related art that is already known to those skilled in the art.
- (Patent Document 1) Korean Patent No. 10-1179611 (Sep. 4, 2012); and (Patent Document 2) Korean Patent Application Publication No. 10-2015-0011668 (Feb. 2, 2015).
- Accordingly, the present invention has been made keeping in mind the above problems occurring in the related art, and the present invention is intended to propose a folding box, in which a soft flexible side part is provided on each of a left side part and a right side part of the folding box, thereby allowing the box to be easily folded and unfolded, and maximizing convenience in use of the box.
- According to one aspect of the present invention, there is provided a folding box, including: a bottom part folded inward by at least one bottom folding means; a front side part connected to a front side of the bottom part; a
rear side part 3 connected to a rear side of the bottom part; a left side part connected to a left side of the bottom part, and folded inward by at least one left folding means; and a right side part connected to a right side of the bottom part, and folded inward by at least one right folding means, wherein the left side part and the right side part each have a flexible side part made of a soft material, which is located at a lower area of folding means on left and right sides and allows the bottom part to be folded inward when the left side part and the right side part are folded inward. - According to an embodiment of the present invention, the left side part may have a first left side panel and a second left side panel that are connected to each other by the left folding means and folded inward, the right side part may have a first right side panel and a second right side panel that are connected to each other by the right folding means and folded inward, and the bottom part may have a first bottom panel and a second bottom panel that are connected to each other by the bottom folding means and folded inward by the flexible side part when the left side part and the right side part are folded inward.
- According to an embodiment of the present invention, the flexible side part of the folding box is formed in a triangular shape, and the first left side panel, the second left side panel, the first right side panel, and the second side panel may be formed in a trapezoidal shape.
- According to the embodiment of the present invention, the bottom folding means, the left folding means, and the right folding means of the folding box may be configured as hinges.
- According to the embodiment of the present invention, each of the left folding means and the right folding means may be provided with a left hinge magnet and a right hinge magnet, respectively, for keeping a state in which the left side part and the right side part are unfolded.
- According to the embodiment of the present invention, the bottom folding means may have a bottom hinge spring and a spring case for providing elastic force to the bottom folding means when the bottom part is folded inward.
- According to another embodiment of the present invention, at a lower side of the rear side part, one or more rear wheels may be provided for moving the folding box.
- According to still another embodiment of the present invention, at a lower side of the front side part, one or more front wheels may be provided for moving the folding box.
- In the case of the present invention, since the flexible side part is provided on the left side part and the right side part, the folding box can be easily folded or unfolded. Therefore, there is effect in which convenience in use is maximized.

right hinge 51 a and a second right hinge 51 b. Specifically, the firstright hinge 51 a may be positioned on a lower side of the right handle and the second right hinge 51 b may be positioned on an upper side thereof. - In addition, since a
right hinge magnet 53 is provided on the firstright hinge 51 a or the second right hinge 51 b, structural force between the firstright side panel 5 a and the secondright side panel 5 b can be increased when the right side part 5 is unfolded. - A first right
hinge reinforcement part 51 c and a second righthinge reinforcement part 51 e may be provided around the firstright hinge 51 a and the second right hinge 51 b so as to protect the firstright hinge 51 a and the second right hinge 51 b and increase strength thereof. - Further, each of the first
right side panel 5 a and the secondright side panel 5 b may have a right edge reinforcement part 51 f on an upper end thereof. Therefore, when theright handle 52 is gripped, it is possible to protect the firstright side panel 5 a and the secondright side panel 5 b and to increase strength thereof. - Referring to
FIGS. 9 and 10 , in the folding box according to the embodiment of the present invention, the bottom folding means 11 may have abottom hinge spring 13 and aspring case 13 a for providing elastic force to the bottom folding means 11 when thebottom part 1 is folded inward. - Specifically, the
spring case 13 a is provided to cover thebottom hinge spring 13. In addition, both ends of thebottom hinge spring 13 are inserted in spring holes 13 b that are respectively provided in the first bottom panel 1 a and the secondbottom panel 1 b, thereby protecting thehinge spring 13 without being exposed to the outside. - Accordingly, in this case of the present invention, when the
bottom part 1 is unfolded, a predetermined force for allowing thebottom part 1 to be folded inward is generated by the elastic force of thebottom hinge spring 13. Thus, when the left side part 4 and the right side part 5 are folded inward, thebottom part 1 can be easily folded inward at the same time. - In addition, a
bottom reinforcement part 11 b may be provided on upper surface of each of the first bottom panel 1 a and the secondbottom panel 1 b to protect the first bottom panel 1 a and the secondbottom panel 1 b and increase strength thereof, as shown inFIG. 12 . That is, at a state in which the folding box is folded, overall thickness of the folding box may be maintained due to thebottom reinforcement part 11 b being positioned between the left side part 4 and the right side part 5, and strength of thebottom part 1 can be increased through thebottom reinforcement part 11 b. - Referring to
FIGS. 8 and 12 , thebottom reinforcement part 11 b may have abottom hinge step 11 a contacted with the bottom folding means 11. Thus, when the items are stored in the folding box in which thebottom part 1 is unfolded, by thebottom hinge step 11 a and tensile force of theflexible side part 6 connected to the first bottom panel 1 a and the secondbottom panel 1 b, the first bottom panel 1 a and the secondbottom panel 1 b may support loads of the items and can maintain a horizontal state without being folded outward. - The
flexible side part 6 of the folding box according to the embodiment of the present invention is formed in a triangular shape, and the firstleft side panel 4 a, the secondleft side panel 4 b, the firstright side panel 5 a, and the secondright side panel 5 b may be formed in a trapezoidal shape. Specifically, theflexible side part 6 is preferably formed in the triangular shape, in which a part of an upper vertex of the triangular shape is removed, to be connected to the firstleft side panel 4 a and the secondleft side panel 4 b, or the firstright side panel 5 a and the secondright side panel 5 b. That is, since theflexible side part 6 is connected to the firstleft side panel 4 a and the secondleft side panel 4 b, or the firstright side panel 5 a and the secondright side panel 5 b, theflexible side part 6 is preferably formed in the triangular shape in which the part of the vertex of the triangular shape is cut by width of each of the left folding means 41 or the right folding means 51. - In addition, left
fastening protrusions 44 and right fastening protrusions (not shown) may be respectively provided on the left side part 4 and the right side part 5, and may be fitted in fastening holes H on left and right edges of theflexible side part 6. In addition, a left fastening cover and a right fastening cover may be fastened to theleft fastening protrusions 44 and the right fastening protrusions, thus theflexible side part 6 may be coupled to each of the left side part 4 and the right side part 5. - Further, a
bottom fastening protrusions 14 may be provided on both ends of an under surface of thebottom part 1, and may be fitted in fastening holes H on a lower edge of theflexible side part 6. In addition, abottom fastening cover 61 c may be fastened to thebottom fastening protrusions 14, thus the bottom part may be coupled to theflexible side part 6. - Therefore, referring to
FIGS. 5 and 6 , since each of the left side part 4 and the right side part 5 have theflexible side part 6, when the left folding means 41 and the right folding means 51 are pushed inward, the left side part 4 and the right side part 5 are folded inward and thebottom part 1 is easily folded inward at the same time. - When an entire area of the left side part 4 and the right side part 5 are made of hard materials, the left side part 4, the right side part 5, and also the
bottom part 1 may not be folded inward. In addition, when theflexible side part 6 provided on the left side part 4 and the right side part 5 is provided as an opened empty space, the items stored in the folding box escape from the folding box through the empty space, which is problematic. In addition, when the entire part of the folding box is made of a soft material, it is difficult to protect the items stored therein and strength of the folding box is lowered, which are problematic. - Accordingly, as the folding box of the present invention has the
flexible side part 6 that is soft, flexible, and triangular shaped on the left side part 4 and the right side part 5, the above-mentioned problems can be solved and convenience of the folding box can be maximized because it is easy to fold and unfold the box. - Referring to
FIG. 13 , according to another embodiment of the present invention, abottom part 1, afront side part 2, arear side part 3, a left side part 4, and a right side part 5 may be connected to each other by one of these methods such as adhesion, welding, fastening, and injection methods. Likewise, a bottom folding means 11, a left folding means 41, and a right folding means 51 may be provided so that a first bottom panel 1 a and a secondbottom panel 1 b, a firstleft side panel 4 a and a secondleft side panel 4 b, and a firstright side panel 5 a and a secondright side panel 5 b can be folded inward in a state of being connected by one of the above-mentioned methods, such as adhesion, welding, fastening, and injection methods. Thus, when external force is applied to the bottom folding means 11, the left folding means 41, and the right folding means 51, abottom part 1, a left side part 4, and a right side part 5 are folded inward together. - Additionally, referring to
FIG. 14 , according to another embodiment of the present invention, one or morerear wheels 33 for moving the folding box may be provided in a protruding shape at a lower side of arear side part 3 toward the ground. When the folding box is provided with therear wheels 33, afront supporter 24 may be provided in a protruding shape at a lower side of afront side part 2 and an opposed side corresponding to therear wheels 33. Thus, when the folding box is stationary, the folding box can stay in a stable horizontal state with the ground. - In addition, referring to
FIG. 15 , according to still another embodiment of the present invention, when the rear wheels are provided at a lower side of arear side part 3, one or more front wheels for moving the folding box may be provided at a lower side of afront side part 2. Thesefront wheels 23 may be provided in the protruding shape toward the ground at an opposite side corresponding to therear wheels 33. - Further, depending on surrounding usage environment and preference of the user, when the
rear wheels 33 are provided on therear side part 3 of the folding box of the present invention, or when thefront wheels 23 and therear wheels 33 are respectively provided together on thefront side part 2 and therear side part 3, aportable handle 34 that is gripped by the user is provided on a side of therear side part 3. Thus, the user can conveniently move the folding box with the stored items by using theportable handle 34. - Additionally, the folding box of the present invention may have a cover (not shown) for covering an upper surface of the folding box. By the cover, the items stored in the folding box can be protected.
