[0054] This invention can be modified in various ways and can have various embodiments. Specific embodiments will be illustrated in the accompanying drawings and described in detail below. The effects, features, and methods of implementing this invention will become clear with reference to the embodiments described in detail below in conjunction with the accompanying drawings. However, this invention is not limited to the embodiments disclosed below, but can be implemented in various forms.

[0055] In the following description, embodiments of the present invention will be described in detail with reference to the accompanying drawings. When describing the invention with reference to the drawings, the same or corresponding components will be given the same reference numerals and repeated descriptions thereof will be omitted.

[0056] In the following embodiments, the terms "first," "second," etc., are not intended to be limiting, but are used to distinguish one constituent element from other constituent elements.

[0057] In the following embodiments, singular expressions include plural expressions unless explicitly indicated in the context.

[0058] In the following embodiments, terms such as "including" or "having" mean the presence of the features or constituent elements described in the specification, and do not preclude the possibility of additional features or constituent elements beyond one other.

[0059] In the following embodiments, when a membrane, region, constituent element, or other part is described as being located on or above other parts, this includes not only the case where it is directly located on other parts, but also the case where other membranes, regions, constituent elements, etc., are located in between.

[0060] In the accompanying drawings, for ease of explanation, the dimensions of the constituent elements may be shown enlarged or reduced. For example, for ease of explanation, the dimensions and thicknesses of the various components shown in the drawings are arbitrarily depicted; therefore, the present invention is not necessarily limited to the cases shown in the drawings.

[0061] In the following embodiments, the x-axis, y-axis, and z-axis are not limited to the three axes of an orthogonal coordinate system, but can be interpreted in a general sense. For example, the x-axis, y-axis, and z-axis may be orthogonal to each other, but may also refer to different directions that are not orthogonal to each other.

[0062] When an embodiment can be implemented in different forms, the specific process sequence can also be performed differently from the described sequence. For example, two processes described consecutively can be performed substantially simultaneously, or they can be performed in the reverse order of the described sequence.

[0063] Figure 1 This is an exploded perspective view of a packaging container for a display device according to an embodiment of the present invention. Figure 2 It shows Figure 1 The diagram shows a cross-sectional view of the packaging container for the display device.

[0064] refer to Figure 1 as well as Figure 2 The packaging container 1 for the display device includes a cover 10, an inner body 20, and a shell 30.

[0065] The cover 10 may include a cover body 11, a first strength reinforcing part 12, 13, 14 and a fixing protrusion, namely a first fixing protrusion 15.

[0066] The cover body 11 can have a groove formed on one side to accommodate a part of the display device DPM.

[0067] The first strength reinforcement portions 12, 13, and 14 can be disposed on the outside of the cover body 11. For example, the first strength reinforcement portions 12, 13, and 14 can be disposed on the top and side of the cover body 11. The first strength reinforcement portions 12, 13, and 14 can protrude or be recessed from the cover body 11 to one side. That is, the first strength reinforcement portions 12, 13, and 14 can be portions of the cover body 11 formed in a concave-convex form. In this case, the first strength reinforcement portions 12, 13, and 14 can include at least one of the first-1 strength reinforcement portion 12, the first-2 strength reinforcement portion 13, and the first-3 strength reinforcement portion 14. In the following, for ease of explanation, the case in which the first strength reinforcement portions 12, 13, and 14 include all of the first-1 strength reinforcement portions 12, the first-2 strength reinforcement portions 13, and the first-3 strength reinforcement portions 14 will be described in detail. The first-1 strength reinforcement portion 12 can be disposed on the top of the cover body 11 along the longitudinal direction (e.g., Figure 1 The first-1 strength reinforcement 12 is formed elongated in the Y direction. One side of the first-1 strength reinforcement 12 can protrude outward from the upper surface of the cover body 11. At this time, the other side of the first-1 strength reinforcement 12 can be recessed from the opposite side of the cover body 11. The first-2 strength reinforcement 13 can be formed on the upper surface of the cover body 11 along the transverse direction (e.g., Figure 1 The first-second strength reinforcement 13 may be formed elongated in the X direction. One side of the first-second strength reinforcement 13 may protrude from the upper surface of the cover body 11, while the other side may be recessed from the opposite side of the cover body 11. The first-third strength reinforcement 14 may be disposed on the side of the cover body 11. For example, the first-third strength reinforcement 14 may be elongated in the vertical direction (e.g., along the X direction). Figure 1The first-3 strength reinforcement 14 is formed elongated in the Z direction. At this time, one side of the first-3 strength reinforcement 14 can be recessed from the side of the cover body 11, and the other side of the first-3 strength reinforcement 14 can protrude from the opposite side of the cover body 11. Each of the first-1 strength reinforcement 12, the first-2 strength reinforcement 13, and the first-3 strength reinforcement 14 as described above can be provided in multiples. It is possible that each first-1 strength reinforcement 12 is spaced apart from each other, each first-2 strength reinforcement 13 is spaced apart from each other, and each first-3 strength reinforcement 14 is spaced apart from each other. At least one of the first-1 strength reinforcement 12, the first-2 strength reinforcement 13, and the first-3 strength reinforcement 14 as described above can not only absorb external forces applied along the length direction or length direction of the first-1 strength reinforcement 12, the first-2 strength reinforcement 13, and the first-3 strength reinforcement 14, but also reduce deformation of the cover 10 due to external forces. That is, the first-1 strength reinforcement 12, the first-2 strength reinforcement 13, and the first-3 strength reinforcement 14 can not only withstand external forces applied along the length direction, but also provide a small margin for external forces applied along the width direction of the first-1 strength reinforcement 12, the first-2 strength reinforcement 13, and the first-3 strength reinforcement 14, thereby absorbing external forces. At this time, the first strength reinforcement 12, 13, and 14 are not limited to the above, and can include any structure that can be formed in a concave-convex form on the outside of the cover body 11 to enhance the strength of the cover body 11.

[0068] The first fixing protrusion 15 can protrude from a portion of the cover body 11. In this case, the first fixing protrusion 15 can fix the display device DPM or limit the movement range of the display device DPM. Multiple first fixing protrusions 15 can be provided, and the multiple first fixing protrusions 15 can be spaced apart from each other along one direction. The first fixing protrusion 15 is perpendicular to the height direction (e.g., Figure 1 The cross-section (in the Z direction) can be variable. Specifically, the cross-section of the first fixed protrusion 15 perpendicular to the height direction can gradually decrease in the direction away from the cover body 11.

[0069] The inner body 20 may include an inner body 21, a folding part 22, a fixing protrusion, namely a second fixing protrusion 23, a fixing protrusion, namely a side fixing protrusion 24, second strength reinforcing parts 26, 27, 28, and a connecting part 29.

[0070] The inner body 21 and the folding portion 22 can be connected by the connecting portion 29. In this case, the inner body 21 can be housed within the housing 30, and the folding portion 22 can be foldably connected to the inner body 21. Additionally, the connecting portion 29 can be positioned at the corner of the housing 30 to absorb external impacts.

[0071] The second fixing protrusion 23 can be disposed protruding from the inner body 21. In this case, multiple second fixing protrusions 23 can be provided, and a portion of the multiple second fixing protrusions 23 can be disposed on an arbitrary curvature, such as the outside of the display device DPM. As described above, the cross-section of the second fixing protrusion 23 perpendicular to the height direction can decrease as it moves away from the inner body 21.

[0072] The side fixing protrusion 24 can protrude from the outside of the folding portion 22. In this case, multiple side fixing protrusions 24 can be provided, and the end of the display device DPM can be inserted between adjacent side fixing protrusions 24. The second strength reinforcement portions 26, 27, and 28 can be in the form where one side of at least one of the inner body 21 and the folding portion 22 protrudes from the outside of the inner body portion 20, and the other side of at least one of the inner body 21 and the folding portion 22 disposed on the opposite side of one side of the inner body 21 and the folding portion 22 is recessed from the outside of the inner body portion 20. That is, the second strength reinforcement portions 26, 27, and 28 can be disposed in a concave-convex form in at least one of the inner body 21 and the folding portion 22. The second strength reinforcement portions 26, 27, and 28 can include a second-first strength reinforcement portion 26 disposed in the folding portion 22, a second-second strength reinforcement portion 27 disposed in the inner body 21, and a second-third strength reinforcement portion 28. At this time, at least one of the second-1 strength reinforcement portion 26, the second-2 strength reinforcement portion 27, and the second-3 strength reinforcement portion 28 may be provided in multiple ways. Alternatively, one side of at least one of the second-1 strength reinforcement portion 26, the second-2 strength reinforcement portion 27, and the second-3 strength reinforcement portion 28 may protrude from the outer surface of at least one of the inner body 21 and the folding portion 22, while the other side of at least one of the second-1 strength reinforcement portion 26, the second-2 strength reinforcement portion 27, and the second-3 strength reinforcement portion 28 may be recessed from the other side of at least one of the inner body 21 and the folding portion 22. In this case, at least one of the second-1 strength reinforcement portion 26, the second-2 strength reinforcement portion 27, and the second-3 strength reinforcement portion 28 may absorb or withstand external forces applied to the inner body portion 20. At this time, the second strength reinforcements 26, 27, and 28 are not limited to those described above, and may include any structure that can be formed in a concave-convex form on the outside of at least one of the inner body 21 and the folding portion 22 to enhance the strength of at least one of the inner body 21 and the folding portion 22. The connecting portion 29 can connect the inner body 21 and the folding portion 22 so that the folding portion 22 can rotate about the inner body 21.

[0073] The housing 30 may have a groove to accommodate the inner body 20. The housing 30 may include a housing body 31 with a groove and third strength reinforcements 34, 35, and 36. Multiple third strength reinforcements 34, 35, and 36 may be provided, and each third strength reinforcement 34, 35, and 36 may be similar to the first strength reinforcements 12, 13, and 14 or the second strength reinforcements 26, 27, and 28 described above. These third strength reinforcements 34, 35, and 36 may include a third-first strength reinforcement 34, a third-second strength reinforcement 35, and a third-third strength reinforcement 36. The third-first strength reinforcement 34 may be disposed on the side of the housing body 31, and the third-second strength reinforcement 35 and the third-third strength reinforcement 36 may be disposed on the bottom surface of the housing body 31. At least one of the strength reinforcement part 34 (3-1), the strength reinforcement part 35 (3-2), and the strength reinforcement part 36 (3-3) can absorb a portion of the external force applied to the housing 30 or reduce the deformation of the housing 30 caused by the external force.

[0074] Alternatively, as described above, one of the cover 10 and the housing 30 may include a first connecting portion 16, and the other of the cover 10 and the housing 30 may include a first receiving portion 33. In the following text, for ease of explanation, the case where the cover 10 includes the first connecting portion 16 and the housing 30 includes the first receiving portion 33 will be described in detail.

[0075] The first joint portion 16 may protrude from the outside of the cover 10. For example, the first joint portion 16 may protrude from the outside of the cover 10 toward the housing 30. In this case, the back side of the first joint portion 16 may be recessed. The first joint portion 16 may be formed elongated along the long side of the cover 10.

[0076] The first receiving portion 33 can be recessed into one side of the housing 30 to engage with the first connecting portion 16. In this case, the shape of the first receiving portion 33 can be the same as or similar to the outer surface of the first connecting portion 16. The first connecting portion 16 can be inserted into the first receiving portion 33 to secure the cover 10 to the housing 30. Alternatively, the first connecting portion 16 and the first receiving portion 33, as described above, can form a group, and multiple such groups can be provided. In this case, the groups including the first connecting portion 16 and the first receiving portion 33 can be arranged spaced apart from each other.

[0077] Alternatively, one of the inner body portion 20 and the housing 30 may include a second connecting portion 32, and the other of the inner body portion 20 and the housing 30 may include a second receiving portion 25. In this case, the second connecting portion 32 and the second receiving portion 25 may be similar to the first connecting portion 16 and the first receiving portion 33, respectively. In the following text, for ease of explanation, the case in which the inner body portion 20 includes the second receiving portion 25 and the housing 30 includes the second connecting portion 32 will be described in detail.

[0078] Alternatively, the second connecting portion 32 and the second receiving portion 25, as described above, can form a group, and multiple such groups can be provided. Furthermore, the groups including the second connecting portion 32 and the second receiving portion 25 can be arranged spaced apart from each other.

[0079] The display device DPM, which has a curved shape, can be accommodated in the packaging container 1 described above. In this case, the front surface of the display device DPM can be curved. As one embodiment, one side of the display device DPM can have a constant radius of curvature throughout the entire display device DPM. As another embodiment, one side of the display device DPM can be formed as a curved surface, with the radius of curvature of one part of the display device DPM differing from that of another part. As yet another embodiment, the cross-section of one side of the display device can also be elliptical.

[0080] To accommodate the display device DPM as described above, a packaging container 1 for the display device can be assembled. Specifically, an inner body portion 20 can be accommodated within a housing 30. At this time, the folding portion 22 can be folded around the inner body portion 21 to place the inner body portion 20 inside the housing 30. In this case, the second connecting portion 32 can be inserted into the second receiving portion 25. Afterward, the display device DPM can be positioned within the inner body portion 20. At this time, the first fixing protrusion 15 and the second fixing protrusion 23 can contact the front or back of the display device DPM. Additionally, the side fixing protrusion 24 provides space at both ends to accommodate the display device DPM. After the display device DPM is accommodated, a cover 10 can be placed on the housing 30. At this time, the first connecting portion 16 is inserted into the first receiving portion 33, thereby connecting the cover 10 and the housing 30. Afterward, although not shown in the accompanying drawings, after inserting the packaging container 1 for the display device inside the outer packaging paper, the outer packaging paper can be sealed and the device moved to the outside.

[0081] Therefore, the packaging container 1 for the display device can not only accommodate the display device DPM with curvature, but also fix the display device DPM while accommodating it, thereby preventing the display device DPM from moving.

[0082] The packaging container 1 for the display device can reduce the transmission of external impacts to the display device DPM. The packaging container 1 for the display device can be easily assembled.

[0083] Figure 3 It shows Figure 1 The back view of the cover shown.

[0084] refer to Figure 3The cover 10 may include a cover body 11, first strength reinforcing portions 12, 13, and 14, a first fixing protrusion 15, and a first connecting portion 16. In this case, the first strength reinforcing portions 12, 13, and 14 may include a first-1 strength reinforcing portion 12, a first-2 strength reinforcing portion 13, and a first-3 strength reinforcing portion 14. Since the cover body 11, the first strength reinforcing portions 12, 13, and 14, and the first connecting portion 16 are the same as those described above, detailed descriptions will be omitted.

[0085] The first fixing protrusion 15 can be multiple depending on the curvature of the display device (not shown). For example, the first fixing protrusion 15 may include a first-1 fixing protrusion 15a, a first-2 fixing protrusion 15b, a first-3 fixing protrusion 15c, and a first-4 fixing protrusion 15d. In this case, the number of first fixing protrusions 15 is not limited to the above, and there may be at least two, so as to contact one side and the other side of the display device respectively. In the following, for ease of explanation, the case where the first fixing protrusion 15 includes the first-1 fixing protrusion 15a, the first-2 fixing protrusion 15b, the first-3 fixing protrusion 15c, and the first-4 fixing protrusion 15d will be described in detail.

[0086] Multiple first-1 fixed protrusions 15a may be provided and arranged spaced apart from each other in the central portion of the cover body 11. In this case, the multiple first-1 fixed protrusions 15a may be arranged in a row with a constant spacing in the width direction of the cover body 11.

[0087] Each of the first-2 fixing protrusions 15b, the first-3 fixing protrusions 15c, and the first-4 fixing protrusions 15d can be symmetrically arranged with the first-1 fixing protrusion 15a as the center. That is, the first-2 fixing protrusions 15b can be arranged on both sides of the first-1 fixing protrusion 15a with the first-1 fixing protrusion 15a as the center, and each of the first-3 fixing protrusions 15c and the first-4 fixing protrusions 15d can also be arranged on both sides of the first-1 fixing protrusion 15a with the first-1 fixing protrusion 15a as the center. In this case, each of the first-3 fixing protrusions 15c can be configured to be further away from the first-1 fixing protrusion 15a than each of the first-2 fixing protrusions 15b, and each of the first-4 fixing protrusions 15d can be configured to be further away from the first-1 fixing protrusion 15a than each of the first-3 fixing protrusions 15c. Furthermore, each of the first-2 fixing protrusions 15b, the first-3 fixing protrusions 15c, and the first-4 fixing protrusions 15d can be provided in multiples. In this case, the multiple first-2 fixing protrusions 15b can be arranged in a row spaced apart from each other in the width direction of the cover body 11, the multiple first-3 fixing protrusions 15c can also be arranged in a row spaced apart from each other in the width direction of the cover body 11, and the multiple first-4 fixing protrusions 15d can be arranged in a row spaced apart from each other in the width direction of the cover body 11.

[0088] One of the first fixed protrusion 15a, the first fixed protrusion 15b, the first fixed protrusion 15c, and the first fixed protrusion 15d may contact one side of the display device or maintain a constant distance from one side of the display device. Additionally, the other of the first fixed protrusion 15a, the first fixed protrusion 15b, the first fixed protrusion 15c, and the first fixed protrusion 15d may contact the other side of the display device or maintain a constant distance from the other side of the display device. Specifically, the first fixed protrusion 15a and the first fixed protrusion 15c may be configured facing the other side of the display device, while the first fixed protrusion 15b and the first fixed protrusion 15d may be configured facing one side of the display device. In another embodiment, the first-1 fixed protrusion 15a and the first-3 fixed protrusion 15c may be configured facing one side of the display device, and the first-2 fixed protrusion 15b and the first-4 fixed protrusion 15d may be configured facing the other side of the display device. In the case described above, the first-1 fixed protrusion 15a, the first-2 fixed protrusion 15b, the first-3 fixed protrusion 15c, and the first-4 fixed protrusion 15d may be arranged in the manner described above for the display device, and in the opposite manner for another display device adjacent to the display device. In this case, one side of the display device may refer to one of the surface displaying the image and its opposite side, and the other side of the display device may refer to the other of the surface displaying the image and its opposite side.

[0089] The first-1 fixed protrusion 15a can be along the length direction of the planar shape of the cover body 11 (e.g., Figure 3 The first-2 fixed protrusion 15b, the first-3 fixed protrusion 15c, and the first-4 fixed protrusion 15d are formed elongatedly in the length direction of the planar shape of the cover body 11. In this case, the planar shape of the face of at least one of the first-2 fixed protrusion 15b, the first-3 fixed protrusion 15c, and the first-4 fixed protrusion 15d facing one of the sides of the display device can be curved. That is, one side of at least one of the first-2 fixed protrusion 15b, the first-3 fixed protrusion 15c, and the first-4 fixed protrusion 15d can be a curved surface to correspond to one of the sides of the display device.

[0090] Therefore, the first fixed protrusion 15 can be configured to correspond to one side and the other side of the display device, thereby reducing the movement of the display device or limiting the range of movement of the display device when it moves.
