Description

FOLDING BOX

The present invention relates to a folding box. In particular, the present invention relates to a folding box having a folding plate that can be raised or folded.

In general, a box has a storage space formed inside by a side panel erected from the main body to store items. When no items are stored, the side panel is folded to minimize the volume of the box. A technology related to this is disclosed in Korean Utility Model Publication No. 20-2011-0003400 (Patent Document 1).

Conventional folding boxes fix the side panels in an upright state through a specific structure, or prevent unintended folding in an upright state. However, conventional folding boxes have a problem in that the side panels have a somewhat weak fixing force in an upright state because they prevent folding of the box side panels by using a low protrusion structure.

A folding box (10) according to one embodiment of the present invention is illustrated in FIGS. 1 to 7. In FIGS. 1 to 7, 'U' indicates the upper direction, 'D' indicates the lower direction, 'L' indicates the left direction, 'R' indicates the right direction, 'O' indicates the outer direction, 'I' indicates the inner direction, 'A' indicates one side, and 'B' indicates the other side.

Figure 1 is a drawing showing a folding box (10) in an upright state with a folding plate (200) erected.

Referring to FIG. 1, the folding box (10) may include a main body (100) including a bottom plate (110). The main body (100) may include four side plates (120a-1, 120a-2, 120b-1, 120b-2) extending upward from all four sides of the bottom plate (110). The side plates may include two pairs of side plates facing each other. The side plates may include a left side plate (120a-1) and a right side plate (120a-2) facing each other. The side plates may include one side plate (120b-1) and the other side plate (120b-2) facing each other. The side plates may include covering pieces (123a, 123b) formed on each of the one side plate (120b-1) and the other side plate (120b-2). The covering pieces (123a, 123b) may include a one-sided covering piece (123a) formed by protruding upward from the center of one-sided side plate (120b-1). The covering pieces (123a, 123b) may include an other-sided covering piece (123b) formed by protruding upward from the center of the other-sided side plate (120b-2). A storage space (101) surrounded by the side plates on all sides and the bottom plate (110) may be formed in the main body (100). The storage space (101) may be open at the top. A transport target (not shown) may be stored in the storage space (101).

The folding box (10) may include a folding plate (200) rotatably connected to the main body (100). The folding plate (200) may be rotatably connected to an upper side of a side plate. The folding plate (200) may include a left folding plate (200a) rotatably connected to a left side plate (120a-1). The folding plate (200) may include a right folding plate (200b) rotatably connected to a right side plate (120a-2). A state in which the folding plate (200) is erected at a certain angle from the main body (100) may be referred to as a standing state. The folding plate (200) may be erected in an upward direction with respect to the left side plate (120a-1) or the right side plate (120a-2). The folding plate (200) may be erected at a 90 degree angle with respect to the bottom plate (110).

In order to easily check the information of the transported object, the folding box (10) according to one embodiment of the present invention is provided with folding plates (200) only on the left and right sides of the main body (100), unlike existing products. Therefore, the information of the transported object can be easily checked on one side and the other side of the box (10). For example, the folding box (10) can be used in a book logistics center (not shown). Since the folding plates (200) are provided only on the left and right sides of the main body (100), it is easy to easily check the information of the transported object, such as the title and cover of the book. The book can be stored upright in the storage space (101). For example, when the folding box (10) is placed on a conveyor belt (not shown) provided in the logistics center and transported, the transport direction of the box (10) corresponds to the left-right direction (L-R) of FIG. 1. Accordingly, when transporting the box (10), the transport object (book) can be supported only by the folding plates (200) installed on the left and right sides of the box (10). That is, when the folding plates (200) are in an upright state, the transport object can be accommodated in the storage space (101) and positioned between the folding plates (200a, 200b) on both sides, so that the transport object can be prevented from coming off.

The folding plate (200) may include stoppers (207a, 207b) formed on one side and the other side, respectively. The stoppers (207a, 207b) may be formed integrally with the folding plate (200). The stoppers (207a, 207b) may include a one-side stopper (207a) formed to protrude from the lower side of the folding plate (200) to one side. The stoppers (207a, 207b) may include an other-side stopper (207b) formed to protrude from the lower side of the folding plate (200) to one side or the other side. The stoppers (207a, 207b) may be formed in an approximately trapezoidal shape.

The main body (100) may include support surfaces (125a, 125b) formed on one side plate (120b-1) and the other side plate (120b-2), respectively. The support surfaces (125a, 125b) may be formed on the left and right sides of the shielding pieces (123a, 123b), respectively. The support surfaces (125a, 125b) may include a left support surface (125a) formed on the left side of the shielding pieces (123a, 123b). The support surfaces (125a, 125b) may include a right support surface (125b) formed on the right side of the shielding pieces (123a, 123b). The left support surface (125a) and the right support surface (125a, 125b) may be formed on the left and right sides of the upper surface of the one side plate (120b-1), respectively (see FIG. 5). The left support surface (125a) and the right support surface (125a, 125b) can be formed on the left and right sides of the upper surface of the other side plate (120b-2), respectively.

Meanwhile, a grip hole (H) into which a hand can be inserted may be formed in the folding plate (200). Accordingly, when a transport object (not shown) is stored in the storage space (101), the folding plate (200) can serve as a handle for the box (10). In addition, a user can hold the folding plate (200) by inserting a hand into the grip hole (H) and lift and move the box (10).

Figure 2 is a drawing showing a folding box (10) with the folding plate (200) folded.

Referring to FIG. 2, a state in which the inner surface of the folding plate (200) is in contact with the upper surface of the main body (100) may be referred to as a folded state. For example, the folded state may be a state in which one stopper (207a) and the other stopper (207b) of the left folding plate (200a) are in contact with the left support surface (125a) of the one side plate (120b-1) and the left support surface (125a) of the other side plate (120b-2), respectively. The folded state may be a state in which one stopper (207a) and the other stopper (207b) of the right folding plate (200b) are in contact with the right support surface (125b) (see FIG. 5) of the one side plate (120b-1) and the right support surface (125b) of the other side plate (120b-2), respectively. At this time, the left folding plate (200a) and the right folding plate (200b) can be spaced apart from each other in the left-right direction. Therefore, the folding plate (200) in the folded state can cover a part of the upper side of the storage space (101). Meanwhile, although not shown in the drawing, another folding box (10) can be loaded on the upper side of the folding box (10) in which the folding plate (200) is in the folded state. At this time, the box loaded on the upper side can be called the upper box, and the box (10) located on the lower side can be called the lower box (10).

When the folding plate (200) is in a folded state, the folding plates (200a, 200b) on both sides can be positioned between the one-sided covering piece (123a) and the other-sided covering piece (123b). Therefore, the one-sided covering piece (123a, 123b) can prevent the left and right folding plates (200a, 200b) from shaking or moving in the one-sided direction. The covering pieces (123a, 123b) can prevent the folding plates (200a, 200b) from being damaged by external impact.

When the folding plate (200) is folded, referring to FIG. 2 and FIG. 7(a), the upper surfaces of the covering pieces (123a, 123b) and the upper surfaces of the stoppers (207a, 207b) can be positioned at the top of the folding box (10). Accordingly, when boxes (10) are stacked vertically, the load of the upper box can be distributed in all directions of the lower box (10), that is, to the covering pieces (123a, 123b) and the stoppers (207a, 207b). That is, the load of the upper box is not directly transmitted to the portion of the folding plate (200) of the lower box (10) located above the storage space (101), so that damage to the folding plates (200a, 200b) can be prevented.

FIG. 3 is a perspective view showing a part of a folding box (10) with a folding plate (200) in an upright state, as shown in FIG. 1.

Referring to FIG. 3, the main body (100) may include a protrusion (130). The protrusion (130) may be formed to protrude toward the folding plate (200) on the upper side of the main body (100). The protrusion (130) may be formed in the center of the left plate and the right plate (120a-1, 120a-2). The protrusion (130) may be formed on the upper surfaces of the left plate and the right plate (120a-1, 120a-2), respectively.

The folding box (10) may include a standing portion (300). A part of the standing portion (300) may be accommodated in the folding plate (200). The standing portion (300) may be accommodated in the center of the folding plate (200). The standing portion (300) may be connected to the main body (100) and the folding plate (200). Therefore, the standing of one folding plate (200) may be stably fixed with only one standing portion (300). This reduces the production cost of the folding box (10).

The folding plate (200) may have a first hole (201) formed at a position corresponding to the position where the standing part (300) is inserted. The first hole (201) may be formed on both the inner and outer surfaces of the folding plate (200). The elastic piece (330) of the standing part (300) may be observed from the outside through the first hole (201).

The folding plate (200) may include a rotation axis (205) formed on the lower side and coupled to the protrusion (130).

Fig. 4 is a perspective view showing a part of a foldable box (10) that has been disassembled. Fig. 5 is a perspective view showing a state in which a standing part (300) is connected to a main body (100) and a folding plate (200) is separated from the main body (100) and the standing part (300). The standing part (300) is in a state in which an insertion piece (320) is inserted into a protrusion (130).

Referring to FIGS. 3 and 4, the protrusion (130) may include a plurality of ribs (133) formed on the inner and outer surfaces. An assembly hole (121) (Hole) (see FIG. 5) into which a rotation shaft (205) of a folding plate (200) is inserted may be formed on one side and the other side (135, 137) of the protrusion (130).

Referring to FIGS. 4 and 5, the standing part (300) can be detachably connected to the main body (100) and the folding plate (200).

The folding box (10) may include a receiving portion in which a standing portion (300) is received. The receiving portion may be formed in the main body (100) and the folding plate (200). The receiving portion may include a standing groove (141) formed in the protrusion (130) of the main body (100). The standing groove (141) may be formed on the upper side (131) of the protrusion (130). The standing groove (141) may be formed on one side and the other side based on the center of the protrusion (130) of the main body (100), and may be referred to as a one-side standing groove (141) and an other-side standing groove (141), respectively.

The standing part (300) may include a body (310). At least a portion of the body (310) may be inserted into the sliding groove (225). The body (310) may be formed in an approximately rectangular parallelepiped shape. A catch projection (313) may be formed on the body (310). The catch projection (313) may be formed on the lower side of the body (310). The catch projection (313) may be formed on the inner surface of the body (310). One catch projection (313) may be formed on each of one side and the other side of the body (310). The catch projection (313) may be formed in a shape that protrudes inwardly from the upper side to the lower side. When the standing part (300) is inserted into the folding plate (200), the catch projection (313) can be caught on the folding plate (200). Therefore, the catch projection (313) can act as a stopper so that when the standing part (300) slides up and down, it slides only within a certain range.

The standing portion (300) may include an insertion piece (320) that is formed to protrude from the body (310) and may be accommodated in the standing groove (141). The insertion piece (320) may be formed one on each of one side and the other side of the body (310). The insertion piece (320) may include a one-side insertion piece (320a) and a other-side insertion piece (320b). The one-side insertion piece (320a) may be accommodated in the one-side standing groove (141). The other-side insertion piece (320b) may be accommodated in the other-side standing groove (141). The one-side insertion piece (320a) and the other-side insertion piece (320b) may be accommodated in the one-side standing groove (141) and the other-side standing groove (141), respectively. Accordingly, since one side and the other side of the standing part (300) are respectively received in one side and the other side of the protrusion (130), the standing of the folding plate (200) can be more stably fixed. The one-side insertion piece (320a) and the other-side insertion piece (320b) can be formed in the same shape.

The standing part (300) may include an elastic piece (330). The elastic piece (330) may be formed on the body (310) and may come into contact with the folding plate (200). The elastic piece (330) may be formed to extend upward from the upper surface of the body (310). The elastic piece (330) may include a first elastic piece (333) extending upward from the upper surface of the body (310). The elastic piece (330) may include a second elastic piece (335) extending upward from the first elastic piece (333) toward the center of the body (310). The first elastic piece (333) may be formed to have a thickness that decreases toward the upper side. Therefore, even if the second elastic piece (335) is elastically deformed multiple times, the first elastic piece (333) is unlikely to be damaged. That is, the durability of the standing part (300) is good. The second elastic piece (335) can come into contact with the inner side of the folding plate (200) when the standing part (300) is inserted into the sliding groove (225). The folding plate (200) can include a support piece (210) formed on the inner side. The standing part (300) can come into contact with the support piece (210). The vertical length of the sliding groove (225) is shorter than the vertical length of the standing part (300). Therefore, the elastic force of the elastic piece (330) can be applied to the folding plate (200). Specifically, the elastic piece (330) can apply an elastic force to the support piece (210) of the folding plate (200) so that the body (310) and the insertion piece (320) are inserted into the standing groove (141). Accordingly, the insertion piece (320) can be brought close to the protrusion (130) of the main body (100) and be in close contact with it due to the elastic force. As a result, the standing state of the folding plate (200) can be maintained simply by rotating the folding plate (200), and the force for maintaining the standing state is improved compared to before, so that the standing state can be stably maintained. In addition, the standing folding plate (200) can be easily folded simply by rotating the folding plate (200).

The elastic piece (330) may include a one-sided elastic piece (330a) extending from one side of the body (310). The elastic piece (330) may include an other-sided elastic piece (330b) extending from the other side of the body (310). The one-sided elastic piece (330a) may include a first elastic piece (333) and a second elastic piece (335). The other-sided elastic piece (330b) may also include a first elastic piece (333) and a second elastic piece (335).

The standing part (300) can be symmetrical on one side and the other side.

The receiving portion may include a sliding groove (225) formed in the folding plate (200). One sliding groove (225) may be formed in the center of the folding plate (200). The sliding groove (225) may be formed surrounded by five inner surfaces (227, 229). That is, the sliding groove (225) may be formed surrounded by four inner side surfaces (229) and an inner upper surface (227) connected to the upper side of the inner side surfaces (229). A supporting piece (210) may be formed on the inner upper surface (227). The supporting pieces (210) may be formed one at each of one side and the other side based on the center of the sliding groove (225). The one-side supporting piece (210a) may be in contact with the one-side elastic piece (330a), and the other-side supporting piece (210b) may be in contact with the other-side elastic piece (330b). The sliding home (225) can be formed so that the lower part is open. The sliding home (225) can be connected to the first hole (201).

The folding plate (200) can be formed with a rotation axis (205) protruding from one side and the other side of the lower side, that is, lower than the sliding groove (225).

A catch groove (204) may be formed on the inner surface of the folding plate (200). The catch groove (204) may be connected to the sliding groove (225). The catch groove (204) may be formed lower than the first hole (201). The catch projection (313) of the standing portion (300) may be accommodated in the catch groove (204). Accordingly, when the standing portion (300) moves up and down as the elastic piece (330) is elastically deformed, the catch projection (313) may slide up and down within a certain range within the catch groove (204). The catch groove (204) may be formed by penetrating the folding plate (200). When a tool or the like is inserted into the engaging groove (204) from the outside and the engaging projection (313) is pressed, the engaging projection (313) is separated from the engaging groove (204), and the standing part (300) can be separated from the sliding groove (225). Accordingly, the standing part (300) can be separated from the folding plate (200).

Meanwhile, the receiving portion may include an assembly groove (235). The assembly groove (235) may be formed in a concave shape on one side (229) of the inner side surfaces (229) of the folding plate (200). At this time, the assembly groove (235) may be formed on one side and the other side of the inner side surface (229). The assembly groove (235) may be connected to the sliding groove (225). The assembly groove (235) may be formed on the inner side of the sliding groove (225). The engaging projection (313) and the assembly groove (235) may serve as a guide when the standing portion (300) is coupled to the folding plate (200).

Referring to FIG. 4 and FIG. 7(a), the receiving portion may include a folding groove (151) in which a part of the standing portion (300) may be received. At this time, a part of the standing portion (300) may be an insertion piece (320). The folding groove (151) may be formed on the inner surface of the main body (100). The folding groove (151) may be formed on the inner surface of the protrusion (130). The folding groove (151) may be formed on the inner side of the standing groove (141). The folding groove (151) may be formed in a concave shape on the protrusion (130).

The protrusion (130) may include an inclined piece (153). The inclined piece (153) may be formed on the inner surface of the protrusion (130). The folding groove (151) may be formed at least in part by the inclined piece (153). The inclined piece (153) may be formed to be inclined outward from the upper side to the lower side. Accordingly, the inclined piece (153) may form the folding groove (151) in a concave shape.

Figure 6 is a perspective view showing the outer surface of the standing part (300).

Referring to Fig. 6, the body (310) of the standing member (300) may include a plurality of reinforcing ribs (311) on the outer surface. The reinforcing ribs (311) may form a grid pattern. Accordingly, the body (310) may have its strength secured while minimizing its weight.

The insertion piece (320) may be formed in a concave-convex shape. The insertion piece (320) may include a contact piece (323) and a connection piece (325). The connection piece (325) may be connected to the contact piece (323). The connection piece (325) may be connected to one side and the other side of the contact piece (323). The connection piece (325) may be connected to the center of the contact piece (323). The connection piece (325) may be formed such that the length of one side is longer than the thickness of the inner and outer sides. The insertion piece (320) may include a plurality of contact pieces (323). The insertion piece (320) may include a plurality of connection pieces (325). As illustrated in FIG. 6, the insertion piece (320) may be composed of three contact pieces (323) and two connection pieces (325). The contact piece (323) and the connecting piece (325) may be formed alternately. Accordingly, a plurality of grooves (not shown in the drawing symbol) may be formed on the outer surface of the insertion piece (320). A plurality of grooves may also be formed on the inner surface of the insertion piece (320) (see FIG. 4). The insertion piece (320) may be formed symmetrically on the inner and outer sides. Accordingly, the insertion piece (320) may have its strength secured while its weight is minimized.

Referring to FIGS. 6 and 7, the insertion piece (320) may be formed as a curved surface at a portion. At this time, the curved surface may be included in the contact piece (323). The contact piece (323) may be formed as an approximately semicircular cross-section in the upper and lower directions. The contact piece (323) may be brought into contact with the main body (100). With the contact piece (323) in contact with the protrusion (130), the standing portion (300) may be rotated at a certain angle with respect to the main body (100) together with the folding plate (200). Therefore, when the standing portion (300) is rotated, the standing and folding of the folding plate (200) may be more easily performed, and damage to the contact piece (323) may be prevented.

The standing part (300) can secure strength while minimizing weight through the structure described above.

Figure 7 is a cross-sectional view illustrating the process in which the folding plate (200) becomes an upright state from a folded state.

Referring to FIG. 7, the protrusion (130) may include a folding lower part (157), an inclined part (153), and a folding inner part (155) in which the upper and lower sides are respectively connected to the inclined part (153) and the folding lower part (157). The folding lower part (157), the folding inner part (155), and the inclined part (153) may form a folding groove (151). The folding inner part (155) may be connected to the upper side of the folding lower part (157). The folding inner part (155) may be arranged to be long in the up-down direction. The folding lower part (157) may be arranged to be long in the inward and outward direction. The folding lower part (157) and the folding inner part (155) may be connected orthogonally to each other. The lower side of the inclined portion (153) can be connected to the folding inner portion (155). The inclined portion (153) can be formed to slope outwardly from the upper side to the lower side. Accordingly, the folding groove (151) can be formed to have an inner and outer width that increases from the upper side to the lower side. The folding groove (151) can be open on the inner side.

The protrusion (130) may include an inner standing piece (143), an outer standing piece (145), and a lower standing piece (147). The inner standing piece (143), the outer standing piece (145), and the lower standing piece (147) may form a standing groove (141). The inner standing piece (143) and the outer standing piece (145) may be spaced apart from each other and face each other. The lower standing piece (147) may be connected to the lower side of the inner standing piece (143) and the lower side of the outer standing piece (145) on the inner and outer sides, respectively. The upper side of the standing groove (141) may be open. The upper surface of the inner standing piece (143) may be formed as a curved surface. The upper surface of the inner standing piece (143) can be formed to slope upward from the inner side to the outer side.

The inner standing piece (143) and the inclined piece (153) may be connected to each other and formed as one piece. At this time, the inner standing piece (143) and the inclined piece (153) formed as one piece may be collectively referred to as a guide piece (160). A plurality of guide pieces (160) may be formed to be spaced apart from each other, and a groove (not shown in the drawing) may be formed between each of the plurality of guide pieces (160) (see FIG. 4). The guide piece (160) may be included in the protrusion (130). The guide piece (160) may be positioned between the folding groove (151) and the standing groove (141). The upper surface of the guide piece (160) may be formed as a curved surface. In addition, the inner and outer thicknesses of the guide piece (160) may be formed in a shape that becomes thicker from the lower side to the upper side. Therefore, the strength of the protrusion (130) may be secured. In addition, even if the folding of the folding plate (200) is repeated and the insertion piece (320) is continuously rubbed against the guide piece (160) as shown in Figs. 7(b) and (c), the possibility of damage to the guide piece (160) is low. In other words, the durability of the protrusion (130) is good.

Below, the process of erecting the folding plate (200) will be described in order with reference to Fig. 7.

First, when the folding plate (200) is folded as shown in Fig. 7(a), the insertion piece (320) can be received in the folding home (151). The folding plate (200) can be in contact with the upper surface of the main body (100). In addition, the insertion piece (320) can be in contact with the inclined piece (153). Specifically, the contact piece (323) can be in contact with the inclined piece (153). The elastic piece (330) can be in contact with the support piece (210). At this time, the elastic force of the elastic piece (330) can be applied to the support piece (210).

Thereafter, when the folding plate (200) is rotated outwardly by about 30 degrees based on the upper surface of the main body (100), the folding plate (200) may be rotated from the upper surface of the body (310) as shown in Fig. 7(b). The standing portion (300) may be moved upwards more than before the folding plate (200) is rotated. The elastic piece (330) may be deformed in shape so that it is pressed more than before the folding plate (200) is rotated. That is, the elastic piece (330) may have a reduced vertical length. Due to this, the elastic piece (330) may apply a stronger elastic force to the support piece (210) than before. At this time, the insertion piece (320) may come into contact with the upper end of the inclined piece (153) among the upper surfaces of the guide piece (160).

Thereafter, when the folding plate (200) is rotated outwardly at an angle of about 75 degrees based on the upper surface of the main body (100), the folding plate (200) may be further spaced from the upper surface of the body (310) than before, as shown in Fig. 7(c). At this time, the insertion piece (320) may be in contact with the upper end of the guide piece (160). The insertion piece (320) may be in contact with the upper end of the inner standing piece (143). In this state, the elastic piece (330) may be in a state of applying elastic force to the support piece (210).

Although not shown in the drawing, during the process of rotating the folding plate (200) from the state shown in Fig. 7(b) to the state shown in Fig. 7(c), the insertion piece (320) can be maintained in contact with the upper surface of the guide piece (160).

Thereafter, when the folding plate (200) is rotated outwardly at an angle of about 90 degrees based on the upper surface of the main body (100), the folding plate (200) can be in an upright state as shown in Fig. 7(d). At this time, the elastic piece (330) can apply elastic force to the support piece (210). Therefore, when the folding plate (200) is rotated at an angle of 90 degrees, the insertion piece (320), which is a part of the standing portion (300), can be received in the standing groove (141) by the elastic force. As a result, the standing portion (300) is fixed to the protrusion (130), and the upright state of the folding plate (200) can be maintained by the standing portion (300). The contact surface of the insertion piece (320) can contact the inner and outer standing portions (143 and 145) respectively. The contact surface may not be in contact with the lower standing piece (147). Therefore, the upper surface of the protrusion (130) may not be in contact with the lower surface of the folding plate (200) and may be spaced apart. Accordingly, when the folding plate (200) is folded or raised, the area where the protrusion (130) and the folding plate (200) come into contact with each other may be minimized. Therefore, even if the folding plate (200) is folded repeatedly, the possibility of damage to the protrusion (130) or the folding plate (200) is low.

The invention described above can maintain the standing state by combining the standing part (300) assembled to the folding plate (200) with the main body (100) when the folding plate (200) is in an upright state as shown in FIG. 7(d). The standing part (300) helps the folding plate (200) to maintain the upright state without separately fixing the folding plate (200). Meanwhile, in a state as shown in FIG. 7(d), when a user folds the upright folding plate (200), the insertion piece (320) of the standing part (300) can be separated from the standing groove (141) by the force of the folding plate (200) to become a state as shown in FIG. 7(c). In this process, the user does not need to separately control the standing part (300), and therefore, the present invention has the effect of reducing the work required to fold and unfold the folding plate (200).

Meanwhile, in order to fold the standing folding plate (200), the processes (d), (c), (b), and (a) of Fig. 7 should be performed in order.
