[0027] The invention will now be described more fully below with reference to the accompanying drawings, in which preferred embodiments of the invention are illustrated. However, the invention may be embodied in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0028] It should also be understood that when a layer is referred to as being "on" another layer or substrate, it can be directly on the other layer or substrate, or an intermediary layer may be present. Conversely, when an element is referred to as being "on" another element directly, no intermediary element is present.

[0029] For ease of description, spatial relative terms such as “below,” “under,” “lower,” “above,” “upper,” etc., may be used herein to describe the relationship between one element or feature and another element (or feature) or feature (or feature) as shown in the figures. It should be understood that, in addition to the orientation depicted in the figures, spatial relative terms are intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “below” or “under” other elements or features will consequently be oriented “above” other elements or features. Thus, the exemplary term “below” can encompass both above and below orientations. The device may be otherwise oriented (rotated 90 degrees or in other orientations), and the spatial relative descriptive terms used herein should be interpreted accordingly.

[0030] It will be understood that while the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and / or parts, these elements, components, regions, layers, and / or parts should not be limited by these terms. These terms are used only to distinguish one element, component, region, layer, or part from another. Therefore, without departing from the teachings herein, “first element,” “first component,” “first region,” “first layer,” or “first part” discussed below may be referred to as a second element, second component, second region, second layer, or second part.

[0031] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms (including “at least one”) unless the context clearly indicates otherwise. “At least one” should not be construed as limiting “a” or “an.” “Or” means “and / or.” As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items. It will be further understood that, when used in this specification, the terms “comprises” and / or “comprising” or “includes” and / or “including” specify the presence of the described features, areas, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, areas, integrals, steps, operations, elements, components, and / or groups thereof.

[0032] As used in this article, "direction" refers to the route that something is facing. For example, the first direction X can be a route from left to right, and the opposite direction to the first direction X can be a route from right to left.

[0033] Throughout the specification, the same reference numerals denote the same components.

[0034] In the following description, specific embodiments will be described with reference to the accompanying drawings.

[0035] Figure 1 This is a perspective view of a glass-covered loading container according to an embodiment. Figure 2 This is a perspective view of the cover glass according to the embodiment. Figure 3 It is along Figure 2 The sectional view taken from line III-III'.

[0036] refer to Figures 1 to 3According to an embodiment, the cover glass loading container 1 may include a tray 10 and a tray cover 20 coupled to the tray 10. The tray 10 may provide space in which one or more cover glasses 1000 may be loaded, and the tray cover 20 may be mounted on the tray 10 to protect the cover glasses 1000 loaded on the tray 10.

[0037] Multiple cover glass units 1000 can be loaded onto tray 10. Multiple cover glass units 1000 can be arranged to form one or more lines. Figure 1 The illustration shows a plurality of cover glass 1000 arranged in a second direction Y and configured to form two lines arranged in a first direction X, but the present disclosure is not limited thereto.

[0038] The cover glass 1000 according to the embodiment may include a glass member 1100, a printed layer 1200 disposed on one surface of the glass member 1100, and a protective layer 1300 disposed on the other surface of the glass member 1100.

[0039] The glass member 1100 may have a rectangular shape in a plan view. The glass member 1100 may include a short side extending in one direction and a long side extending in another direction intersecting the first direction. One surface of the glass member 1100 may include a flat surface. Another surface of the glass member 1100 may include edges that are respectively disposed along the long side in another direction and in a direction opposite to the first direction, and respectively curved in one direction and in a direction opposite to the first direction. However, this disclosure is not limited thereto, and in another embodiment, the other surface of the glass member 1100 may include edges that are respectively disposed along the short side in one direction and in a direction opposite to the first direction, and respectively curved in another direction and in a direction opposite to the first direction. The other surface of the glass member 1100 may also include edges that are respectively disposed along the long side and curved in another direction and in a direction opposite to the first direction, and edges that are respectively disposed along the short side and curved in one direction and in a direction opposite to the first direction.

[0040] The glass component 1100 can be formed as part of a display device (not shown) through certain processes. The glass component 1100 can be disposed on the front surface of the display device (not shown) to cover other components constituting the display device (not shown), such as a display panel (not shown).

[0041] The glass component 1100 may be made of a light-transmitting material. The glass component 1100 may include silicon dioxide (SiO2) as its main component, and may also include components such as aluminum oxide (Al2O3), lithium oxide (Li2O2), and sodium oxide (Na2O), but this disclosure is not limited thereto, and in another embodiment, the glass component 1100 may also include other components. In one embodiment, the glass component 1100 may include a glass ceramic containing alkaline aluminosilicates.

[0042] The printed layer 1200 may be disposed on one side edge and the other side edge in one direction of a surface of the glass member 1100. That is, the printed layer 1200 may be disposed on the opposing surfaces of the glass member 1100, including the curved edges. On at least one surface of the glass member 1100, the printed layer 1200 may partially block light emitted from a display panel (not shown) to which the glass member 1100 is attached. The printed layer 1200 may be made of a light-shielding member or a predetermined ink.

[0043] On one surface of the glass member 1100, the printed layer 1200 may partially overlap with the area of ​​the curved edge. The printed layer 1200 may be configured to extend in another direction. When the cover glass 1000 is loaded onto the tray 10, it is necessary to prevent damage to the printed layer 1200 formed on the cover glass 1000.

[0044] A protective layer 1300 may be disposed on the other surface of the glass member 1100. The protective layer 1300 may be configured to protect the other surface of the glass member 1100. The protective layer 1300 may be configured to protect the other surface of the glass member 1100 from external environmental influences during the manufacturing process of the display device (not shown) to which the cover glass 1000 is attached. The protective layer 1300 may be disposed over the entire area of ​​the other surface of the glass member 1100 and also cover the curved edges of the glass member 1100.

[0045] The protective layer 1300 may be a protective film. For example, the protective layer 1300 may be made of at least any one of polyethylene terephthalate (PET), thermoplastic polyurethane (TPU), polyvinyl chloride (PVC), polypropylene (PP), and polyimide (PI), or a mixture thereof, but this disclosure is not limited thereto.

[0046] The cover glass 1000 may also include an adhesive member (not shown) disposed between the protective layer 1300 and the glass member 1100. However, this disclosure is not limited thereto, and in another embodiment, one surface of the protective layer 1300 in contact with the glass member 1100 may itself be adhesive.

[0047] The thickness t1 of the cover glass 1000 can be equal to the sum of the thickness t2 of the glass component 1100 and the thickness t3 of the protective layer 1300. The thickness t2 of the glass component 1100 can occupy a large portion of the thickness t1 of the cover glass 1000. For example, the thickness t2 of the glass component 1100 can occupy about 70% or more, about 80% or more, or about 90% or more of the thickness t1 of the cover glass 1000. The thickness t1 of the cover glass 1000 can be less than or equal to about 0.8 mm, less than or equal to about 1.0 mm, or less than or equal to about 2.0 mm, but is not limited thereto.

[0048] The cover glass 1000 can be loaded onto the pallet 10 for transport or storage. The pallet 10 may have a structure that prevents the cover glass 1000 from breaking and damage to the printed layer 1200 during transport or storage. The structure of the pallet 10 that allows the cover glass 1000 to be stably loaded onto the pallet 10 and prevents damage to the printed layer 1200 will be described below.

[0049] Figure 4 This is a perspective view of the tray according to the embodiment. Figure 5 This is a side view of the tray according to the embodiment. Figure 6 This is a plan view of the tray according to the implementation method.

[0050] refer to Figures 4 to 6 According to the embodiment, the tray 10 may include a main body portion 100 and a guide portion 200, a partition portion 300 and a separation wall 400 disposed on the main body portion 100.

[0051] The main body portion 100 may include a plurality of sidewalls OW. The main body portion 100 may have a structure in which a guide portion 200 and a partition portion 300, described below, are disposed on the bottom surface of the main body portion 100, and the sidewalls OW surround the guide portion 200 and the partition portion 300. The guide portion 200 may have a shape that protrudes from the sidewalls OW of the main body portion 100 toward the inward side of the main body portion 100. The guide portion 200 may be integrally formed with the bottom surface of the main body portion 100 and the sidewalls OW.

[0052] The sidewalls OW of the main body 100 have a predetermined height and thickness (in the third direction Z). The sidewalls OW are located at the outer boundary of the bottom surface of the main body 100, and their height and thickness can vary depending on the number of cover glass 1000s loaded on the tray 10. The sidewalls OW may include a first sidewall OW1 and a third sidewall OW3 extending in the first direction X, and a second sidewall OW2 and a fourth sidewall OW4 extending in the second direction Y. Sidewalls OW extending in the same direction may be arranged opposite to each other. A receiving portion RA may be defined in the area between them, into which the cover glass 1000 is inserted for loading. The receiving portion RA may be defined by the bottom surface of the main body 100, the side surface of the guide portion 200, and the side surface of the partition portion 300.

[0053] The sidewall OW of the main body 100 can be configured to partially surround the edge of the cover glass 1000. The sidewall OW of the main body 100 can have a lower height than the loaded cover glass 1000, but it prevents the cover glass 1000 from falling off between the guide portions 200 when the cover glass 1000 is loaded on the receiving portion RA for transport or storage.

[0054] Although the accompanying drawings show a case where the corner where the sidewalls OW intersect is angular, this disclosure is not limited thereto, and in another embodiment, the corner may also have a rounded shape.

[0055] In some embodiments, at least some of the sidewalls OW of the main body portion 100 may have a flat upper surface extending in one direction, and the remaining sidewalls OW may have a partially concave curved upper surface.

[0056] like Figure 4 and Figure 5 As shown, the second sidewall OW2 and the fourth sidewall OW4 may have flat upper surfaces extending in one direction (i.e., the second direction Y), and the first sidewall OW1 and the third sidewall OW3 may have partially concave curved upper surfaces. In other words, the first sidewall OW1 and the third sidewall OW3 may have partially different heights, and the area surrounded by the sidewall OW can be partially exposed through the first sidewall OW1 and the third sidewall OW3. When viewing the tray 10 from the front (see...), Figure 5 The upper surface of the third sidewall OW3 may include a recessed portion PA that is partially recessed downward from the central portion, and in the third direction Z, the central portion of the third sidewall OW3 may have a lower height than the height at the opposite side portion of the third sidewall OW3.

[0057] The first sidewall OW1 and the third sidewall OW3 of the main body 100 may define a partially recessed portion PA. When the cover glass 1000 is separated from the tray 10, an external mechanism can be secured to the cover glass 1000 through the recessed portion PA of the first sidewall OW1 and the third sidewall OW3. As will be described below, the receiving portion RA, which serves as the space for loading the cover glass 1000, can be arranged in a second direction Y, which is the direction in which the first sidewall OW1 and the third sidewall OW3 are opposite to each other. The cover glass 1000 loaded on the receiving portion RA can also be arranged in the tray 10 in the second direction Y for loading. Since the recessed portion PA is formed in the first sidewall OW1 and the third sidewall OW3, the external mechanism can easily approach the cover glass 1000 in the second direction Y, and the cover glass 1000 loaded in the second direction Y can be sequentially separated from the tray 10. However, this disclosure is not limited thereto, and in another embodiment, the shape of the sidewall OW of the main body 100 may be changed within a predetermined range.

[0058] According to the embodiment, the tray 10 may define a plurality of receiving portions RA. The plurality of receiving portions RA may be arranged to form one or more receiving lines RL arranged in one direction. The direction in which the plurality of receiving portions RA are arranged to form a single receiving line RL (i.e., the second direction Y) may be perpendicular to the direction in which each receiving portion RA extends (i.e., the first direction X).

[0059] When multiple receiving lines RL exist, they can be arranged in a direction perpendicular to the direction in which each receiving line RL extends (i.e., the first direction X). For example, the receiving lines RL included in the tray 10 may include a first receiving line RL1 extending in the second direction Y and a second receiving line RL2 disposed on one side of the first receiving line RL1 in the first direction X. Although Figure 6 Two receiving lines RL extending in the second direction Y and adjacent to each other in the first direction X are shown, but the extension direction of the receiving lines RL and the number of receiving lines RL according to the invention are not limited thereto.

[0060] The first receiving line RL1 can be disposed between the fourth side wall OW4 and the separation wall 400, and can include a first receiving portion RA1. The second receiving line RL2 can be disposed between the second side wall OW2 and the separation wall 400, and can include a second receiving portion RA2.

[0061] A guide portion 200 is disposed within the main body portion 100. Specifically, the guide portion 200 may be disposed on the bottom surface of the main body portion 100. Multiple guide portions 200 may be spaced apart from each other. For example, the guide portions 200 may be spaced apart at equal intervals in the second direction Y. Adjacent guide portions 200 may define an edge receiving portion PC disposed between the guide portions 200. The edge receiving portion PC will be described in detail below.

[0062] The guide portion 200 may include a first guide portion 210 and a second guide portion 220 disposed in the first receiving line RL1 and disposed opposite to each other. The guide portion 200 may also include a third guide portion 230 and a fourth guide portion 240 disposed in the second receiving line RL2 and disposed opposite to each other.

[0063] The first guide portion 210 and the second guide portion 220 may protrude in opposite directions. For example, the first guide portion 210 and the second guide portion 220 may be arranged to face each other in a first direction X. The first guide portion 210 may have a first direction X (i.e., Figure 6 The shape protruding from the fourth sidewall OW4 in the direction to the right (from the center), and the second guide portion 220 may have a shape in the opposite direction to the first direction X (i.e., Figure 6 The shape protrudes from the separation wall 400 (described below) in a direction from left to right. The first guide portion 210 and the second guide portion 220 may be arranged in the first direction X. The first guide portion 210 and the second guide portion 220, which are arranged opposite to each other, may have a structure symmetrical about a virtual line that is equidistant from the first guide portion 210 and the second guide portion 220 and extends in the second direction Y.

[0064] The first guide portion 210 may be disposed on the bottom surface of the main body portion 100. Furthermore, the first guide portion 210 may have a shape protruding inward from the inner wall of the fourth side wall OW4, and may have a structure integrally formed with the fourth side wall OW4. However, this disclosure is not limited thereto, and in another embodiment, the first guide portion 210 may also be formed as a separate component on the bottom surface of the main body portion 100.

[0065] The tray 10 may include a plurality of first guide portions 210 projecting from a side wall OW (i.e., the fourth side wall OW4). The plurality of first guide portions 210 may be arranged to be spaced apart from each other in the direction in which the side wall OW (i.e., the fourth side wall OW4) on which the first guide portions 210 are disposed. For example, as Figure 6 As shown, the first guide portion 210 may be disposed on the inner sidewall of the fourth sidewall OW4 and arranged in the second direction Y.

[0066] The second guide portion 220 may be disposed on the bottom surface of the main body portion 100 and on the separation wall 400, the separation wall 400 being configured to extend on the bottom surface of the main body portion 100 in the second direction Y. As described above, the second guide portion 220 may have a shape substantially the same as the first guide portion 210 and a structure symmetrical to the first guide portion 210. That is, the second guide portion 220 may have a shape protruding from the separation wall 400 in a direction opposite to the first direction X, and may have a structure integrally formed with the separation wall 400. However, this disclosure is not limited thereto, and in another embodiment, the second guide portion 220 may also be formed as a separate component on the bottom surface of the main body portion 100.

[0067] Multiple second guide portions 220 may be spaced apart from each other in the direction in which the separation wall 400 extends. For example, as Figure 6 As shown, the second guide portion 220 may have a shape that protrudes from the other side surface of the separation wall 400 in the first direction X, and may be arranged in the second direction Y. Therefore, a plurality of first receiving portions RA1 may also be arranged in the direction in which the first guide portion 210 and the second guide portion 220 are arranged.

[0068] The third guide portion 230 and the fourth guide portion 240 may protrude in opposite directions. For example, the third guide portion 230 and the fourth guide portion 240 may be arranged to be opposite each other in the first direction X.

[0069] The third guiding section 230 may have a first direction X (i.e., Figure 6 The fourth guide portion 240 may have a shape that protrudes from the second sidewall OW2 in a direction opposite to the first direction X, and a plurality of third guide portions 230 and a plurality of fourth guide portions 240 may be arranged in the second direction Y. The third guide portions 230 and the fourth guide portions 240, which are arranged opposite to each other, may have a structure symmetrical about a virtual line that is equidistant from the third guide portions 230 and the fourth guide portions 240 and extends in the second direction Y.

[0070] Since other details relating to the third guide portion 230 and the fourth guide portion 240 are substantially the same as those for the first guide portion 210 and the second guide portion 220, additional descriptions will be omitted.

[0071] The arrangement orientation of the first guide section 210, the second guide section 220, the third guide section 230, and the fourth guide section 240 is not limited to... Figure 6The direction shown is indicated. In some cases, the first guide portion 210 and the fourth guide portion 240 may be disposed on the inner sidewall of the first sidewall OW1 or the third sidewall OW3, and the separation wall 400 on which the second guide portion 220 is disposed may extend in the first direction X on the bottom surface of the main body portion 100. However, as described above, the arrangement direction of the first guide portion 210, the second guide portion 220, the third guide portion 230 and the fourth guide portion 240 may be the same as the arrangement direction of the receiving portion RA and the direction in which the plurality of cover glasses 1000 are sequentially loaded.

[0072] To allow the cover glass 1000 to separate smoothly, the arrangement directions of the first guide portion 210, the second guide portion 220, the third guide portion 230, and the fourth guide portion 240 can correspond to the directions in which the sidewalls OW, in which the recessed portion PA is defined, are opposite to each other. That is, as shown in the figures, since the recessed portion PA is defined in the first sidewall OW1 and the third sidewall OW3, the first guide portion 210, the second guide portion 220, the third guide portion 230, and the fourth guide portion 240 can be arranged in the second direction Y, which is the direction in which the first sidewall OW1 and the third sidewall OW3 are opposite to each other. On the other hand, when the recessed portion PA is defined in the second sidewall OW2 and the fourth sidewall OW4, the first guide portion 210 and the second guide portion 220 can be arranged in the first direction X, which is the direction in which the second sidewall OW2 and the fourth sidewall OW4 are opposite to each other.

[0073] The partition portion 300 may include a first partition portion 310 disposed between the first guide portion 210 and the second guide portion 220, and a second partition portion 320 disposed between the third guide portion 230 and the fourth guide portion 240. A plurality of partition portions 300 may be disposed on the bottom surface of the main body portion 100 and may be arranged to be spaced apart from each other in the second direction Y. A first central receiving portion CR1 may be defined between a plurality of adjacent first partition portions 310, and a second central receiving portion CR2 may be defined between a plurality of adjacent second partition portions 320.

[0074] A single first partition portion 310 may be configured to correspond to a single first guide portion 210 and a single second guide portion 220. The first guide portion 210, the second guide portion 220, and the first partition portion 310 may constitute a single group, and multiple groups may be arranged on the bottom surface of the main body portion 100 in the second direction Y. Between adjacent groups, a first receiving portion RA1 on which the cover glass 1000 is mounted may be defined, each of the adjacent groups consisting of a single first guide portion 210, a single second guide portion 220, and a single first partition portion 310.

[0075] Similarly, a single second partition portion 320 can be configured to correspond to a single third guide portion 230 and a single fourth guide portion 240. The third guide portion 230, the fourth guide portion 240, and the second partition portion 320 can form a single group, and multiple groups can be arranged on the bottom surface of the main body portion 100 in the second direction Y. Between adjacent groups, a second receiving portion RA2 on which the cover glass 1000 is mounted can be defined, each of the adjacent groups consisting of a single third guide portion 230, a single fourth guide portion 240, and a single second partition portion 320.

[0076] Meanwhile, according to the embodiment, at least one surface of the cover glass 1000 may have a predetermined curvature and a curved shape. When the cover glass 1000 is loaded onto the tray 10, the edges of the cover glass 1000 may be loaded between adjacent guide portions 200, and the flat surfaces of the cover glass 1000 may be loaded between adjacent partition portions 300.

[0077] The guide portion 200 may have a structure that prevents the printed layer 1200 disposed on one surface of the cover glass 1000 from contacting another component. The shape and structure of the guide portion 200 will be described in more detail below with reference to other accompanying drawings.

[0079] refer to Figures 7 to 10 According to the embodiment, the guide portion 200 included in the tray 10 may have a structure that allows the cover glass 1000 with a small thickness to be stably mounted on the receiving portion RA and prevents damage to the printed layer 1200.

[0080] The following description is based on the first receiving portion RA1, the first guide portion 210, the second guide portion 220 and the first separation portion 310 provided in the first receiving line RL1, but the description can also be applied to the second receiving line RL2.

[0081] Specifically, the first guide portion 210 may include a first main protrusion 211, a first sub-protrusion 212, and a second sub-protrusion 213, the first sub-protrusion 212 and the second sub-protrusion 213 protruding from the first main protrusion 211 in the second direction Y and in a direction opposite to the second direction Y, respectively. The second guide portion 220 may include a second main protrusion 221, a third sub-protrusion 222, and a fourth sub-protrusion 223, the third sub-protrusion 222 and the fourth sub-protrusion 223 protruding from the second main protrusion 221 in the second direction Y and in a direction opposite to the second direction Y, respectively.

[0082] As described above, the first partition portion 310 may be disposed between the first guide portion 210 and the second guide portion 220. Although the accompanying drawings show a case in which the first partition portion 310 is disposed spaced apart from the first guide portion 210 and the second guide portion 220, the present disclosure is not limited thereto, and in another embodiment, the first partition portion 310 may also be connected to the first guide portion 210 and the second guide portion 220.

[0083] The first guide portion 210 and the second guide portion 220 may have a structure that is symmetrical about a virtual line extending in the second direction Y and dividing the first dividing portion 310 disposed between the first guide portion 210 and the second guide portion 220 into two equal parts.

[0084] The first main protruding portion 211 may have a first direction X (i.e., Figure 8 The first sub-protrusion 212 may have a shape that protrudes from the first main protrusion 211 in the second direction Y. The second sub-protrusion 213 may have a shape that protrudes from the first main protrusion 211 in the opposite direction to the second direction Y. In a single first guide portion 210, the directions in which the first sub-protrusion 212 and the second sub-protrusion 213 protrude may be opposite.

[0085] The first sub-protrusion 212 and the second sub-protrusion 213 can be configured to protrude alternately. The alternating protrusion of the first sub-protrusion 212 and the second sub-protrusion 213 can mean that the protruding ends of the first sub-protrusion 212 and the second sub-protrusion 213 are alternately positioned, rather than aligned along a straight line in the second direction Y. The protruding end of the first sub-protrusion 212 can refer to the point where it is positioned closest to the side in the second direction Y, and the protruding end of the second sub-protrusion 213 can refer to the point where it is positioned furthest in the direction opposite to the second direction Y.

[0086] Furthermore, the first sub-protrusion 212 and the second sub-protrusion 213 may partially overlap in the second direction Y. This partial overlap in the second direction Y can mean that portions of the first sub-protrusion 212 and the second sub-protrusion 213 are positioned opposite each other in the second direction Y.

[0087] In the first guide portion 210, a first sub-protrusion 212 may be disposed between the first main protrusion 211 and the fourth sidewall OW4. The first sub-protrusion 212 may be partially connected to the first main protrusion 211 and the fourth sidewall OW4. The first sub-protrusion 212 may have a structure in which the thickness increases and then decreases in the direction from the fourth sidewall OW4 toward the protruding end portion of the first main protrusion 211. Here, the thickness of the first sub-protrusion 212 may refer to the thickness in the second direction Y. Furthermore, the protruding end portion of the first main protrusion 211 may refer to a side end portion of the first main protrusion 211 in the first direction X.

[0088] Specifically, the thickness of the other end portion of the first sub-protrusion 212 in the first direction X can be greater than the thickness of one end portion of the first sub-protrusion 212 in the first direction X. However, the thickness of the other end portion of the first sub-protrusion 212 in the first direction X can be less than the thickness of the first sub-protrusion 212 at its protruding end portion. At one side of the first sub-protrusion 212 in the first direction X, one side surface of the first main protrusion 211 in the second direction Y can be exposed to the first edge receiving portion PC1.

[0089] The first sub-protrusion 212 may be connected to the fourth sidewall OW4 at one end in the first direction X, and the first sub-protrusion 212 may be connected to the first main protrusion 211 at one end in the first direction X. A side surface of the first sub-protrusion 212 exposed in the second direction Y may be disposed between the fourth sidewall OW4 and a side surface of the first main protrusion 211 in the second direction Y.

[0090] The second sub-protrusion 213 can be configured to protrude from the protruding end portion of the first main protrusion 211 in a direction opposite to the second direction Y. The second sub-protrusion 213 can have a structure in which the thickness increases and then decreases in the direction from the protruding end portion of the first main protrusion 211 toward the fourth sidewall OW4. Here, the thickness of the second sub-protrusion 213 can refer to the thickness in the second direction Y.

[0091] Specifically, the thickness of one side end of the second sub-protrusion 213 in the first direction X can be greater than the thickness of the other side end of the second sub-protrusion 213 in the first direction X. However, the thickness of one side end of the second sub-protrusion 213 in the first direction X can be less than the thickness of the second sub-protrusion 213 at its protruding end portion. On the other side of the second sub-protrusion 213 in the first direction X, the other side surface of the first main protrusion 211 in the second direction Y can be exposed to the first edge receiving portion PC1.

[0092] The second sub-protrusion 213 may be connected to the first main protrusion 211 via its other end portion and one end portion in the first direction X. An exposed side surface of the second sub-protrusion 213 in the first direction X and the other side surface of the second sub-protrusion 213 in the second direction Y may be disposed between the first main protrusion 211 via one side surface in the first direction X and the other side surface of the first main protrusion 211 in the second direction Y.

[0093] Compared to the second sub-protrusion 213 of another first guide portion 210 which is positioned adjacent to a first guide portion 210 in the second direction Y, the first sub-protrusion 212 of a first guide portion 210 can be positioned further away in the opposite direction to the second direction Y, so as to allow the cover glass 1000 to be accommodated between the first sub-protrusion 212 and the second sub-protrusion 213 of the adjacent first guide portion 210.

[0094] In the second guide portion 220, the second main protrusion 221 may have a shape that protrudes from the separation wall 400 in a direction opposite to the first direction X. The third sub-protrusion 222 may have a shape that protrudes from the second main protrusion 221 in a second direction Y. The fourth sub-protrusion 223 may have a shape that protrudes from the second main protrusion 221 in a direction opposite to the second direction Y. In a single second guide portion 220, the directions in which the third sub-protrusion 222 and the fourth sub-protrusion 223 protrude may be opposite.

[0095] The third sub-protrusion 222 and the fourth sub-protrusion 223 can be alternately arranged. In the following text, the positional relationship between the third sub-protrusion 222 and the fourth sub-protrusion 223 can refer to the positional relationship between the protruding end portion of the third sub-protrusion 222 and the protruding end portion of the fourth sub-protrusion 223. That is, the alternating arrangement of the third sub-protrusion 222 and the fourth sub-protrusion 223 can mean that the protruding end portion of the third sub-protrusion 222 and the protruding end portion of the fourth sub-protrusion 223 are alternately arranged. Furthermore, the protruding end portion of the third sub-protrusion 222 can refer to the point where the third sub-protrusion 222 is positioned closest to the side in the second direction Y, and the protruding end portion of the fourth sub-protrusion 223 can refer to the point where the fourth sub-protrusion 223 is positioned furthest in the direction opposite to the second direction Y.

[0096] The third sub-protrusion 222 may be disposed between the second main protrusion 221 and the separation wall 400. The third sub-protrusion 222 may be partially connected to both the second main protrusion 221 and the separation wall 400. The third sub-protrusion 222 may have a structure in which the thickness increases and then decreases in the direction from the separation wall 400 toward the protruding end portion of the second main protrusion 221. Here, the thickness of the third sub-protrusion 222 may refer to the thickness in the second direction Y. Furthermore, the protruding end portion of the second main protrusion 221 may refer to the other end portion of the second main protrusion 221 in the first direction X.

[0097] Specifically, the thickness of one side end of the third sub-protrusion 222 in the first direction X can be greater than the thickness of the other side end of the third sub-protrusion 222 in the first direction X. However, the thickness of one side end of the third sub-protrusion 222 in the first direction X can be less than the thickness of the third sub-protrusion 222 at its protruding end portion. On the other side of the third sub-protrusion 222 in the first direction X, one side surface of the second main protrusion 221 in the second direction Y can be exposed to the second edge receiving portion PC2.

[0098] The third sub-protrusion 222 may be connected to one side end of the separation wall 400 in the first direction X, and the other side end of the third sub-protrusion 222 in the first direction X may be connected to the second main protrusion 221. An exposed side surface of the third sub-protrusion 222 in the second direction Y may be disposed between the separation wall 400 and the side surface of the second main protrusion 221 in the second direction Y.

[0099] The fourth sub-protrusion 223 can be configured to protrude from the protruding end portion of the second main protrusion 221 in a direction opposite to the second direction Y. The fourth sub-protrusion 223 can have a structure in which the thickness increases and then decreases in the direction from the protruding end portion of the second main protrusion 221 toward the separation wall 400. Here, the thickness of the fourth sub-protrusion 223 can refer to the thickness in the second direction Y.

[0100] Specifically, the thickness of the other end portion of the fourth sub-protrusion 223 in the first direction X can be greater than the thickness of one end portion of the fourth sub-protrusion 223 in the first direction X. However, the thickness of the other end portion of the fourth sub-protrusion 223 in the first direction X can be less than the thickness of the fourth sub-protrusion 223 at its protruding end portion. On one side of the fourth sub-protrusion 223 in the first direction X, the other surface of the second main protrusion 221 in the second direction Y can be exposed to the second edge receiving portion PC2.

[0101] The fourth sub-protrusion 223 may be connected to the second main protrusion 221 via one side end portion and the other side end portion in the first direction X. The exposed other side surface of the fourth sub-protrusion 223 in the first direction X and the other side surface of the fourth sub-protrusion 223 in the second direction Y may be disposed between the other side surface of the second main protrusion 221 in the first direction X and the other side surface of the second main protrusion 221 in the second direction Y.

[0102] The fourth sub-protrusion 223 can be set to be farther than the third sub-protrusion 222 in the second direction Y.

[0103] The first receiving portion RA1, defined by the first guide portion 210, the second guide portion 220, the fourth sidewall OW4, the first partition portion 310, and the separation wall 400, will be described in detail below.

[0104] The tray 10 according to an embodiment may include a plurality of receiving portions RA. Each receiving portion RA may have a shape extending in a first direction X. The plurality of receiving portions RA may be arranged in a second direction Y. The plurality of receiving portions RA may include a first receiving portion RA1 and a second receiving portion RA2, the first receiving portion RA1 being included in a first receiving line RL1 disposed between the fourth sidewall OW4 and the separation wall 400, and the second receiving portion RA2 being included in a second receiving line RL2 disposed between the second sidewall OW2 and the separation wall 400. Hereinafter, the receiving portions RA will be described based on the first receiving portion RA1 included in the first receiving line RL1, but this description may also apply to the second receiving portion RA2.

[0105] The first receiving portion RA1 may include a first central receiving portion CR1 extending in the first direction X and edge receiving portions PC disposed on one side and the other side of the first central receiving portion CR1 in the first direction X. The first central receiving portion CR1 may be defined as the region between first dividing portions 310 that are adjacent to each other in the second direction Y. The first central receiving portion CR1 may have a shape extending in the first direction X. When the cover glass 1000 is mounted on the first receiving portion RA1, the region between the opposite side edges of the cover glass 1000 may be mounted on the first central receiving portion CR1. In a plan view, the first central receiving portion CR1 may have a rectangular shape including a long side in the first direction X and a short side in the second direction Y.

[0106] The edge receiving portion PC can be disposed on each of one side and the other side of the first central receiving portion CR1 in the direction extending from the first central receiving portion CR1. The edge receiving portion PC may include a first edge receiving portion PC1 disposed on the other side of the first central receiving portion CR1 in the first direction X and a second edge receiving portion PC2 disposed on one side of the first central receiving portion CR1 in the first direction X. The edge receiving portion PC can be spatially connected to the first central receiving portion CR1.

[0107] The first edge receiving portion PC1 is the space between adjacent first guide portions 210 and can be defined by the adjacent first guide portions 210 and the fourth sidewall OW4 connected to the first guide portions 210.

[0108] The first edge receiving portion PC1 may include a first sub-edge receiving portion PC11, the first sub-edge receiving portion PC11 being disposed in a first direction X (i.e., ...). Figure 8 The first edge receiving portion PC1 is located at a position starting from the fourth sidewall OW4 in the direction from the center to the right, and corresponds to the region extending to the protruding end portion of the first sub-protrusion 212. The first edge receiving portion PC1 may also include a second sub-edge receiving portion PC12, which extends from the protruding end portion of the first main protrusion 211 in a direction opposite to the first direction X, and corresponds to the region extending to the protruding end portion of the second sub-protrusion 213. The first edge receiving portion PC1 may also include a third sub-edge receiving portion PC13 disposed between the first sub-edge receiving portion PC11 and the second sub-edge receiving portion PC12. In the first edge receiving portion PC1, the third sub-edge receiving portion PC13 may correspond to the region in the first direction X from the protruding end portion of the first sub-protrusion 212 to the protruding end portion of the second sub-protrusion 213.

[0109] When the cover glass 1000 is loaded onto the tray 10 according to the embodiment, at least a portion of the printed layer 1200 of the cover glass 1000 may be disposed in the first sub-edge receiving portion PC11. The cover glass 1000 may be configured such that the printed layer 1200 is on the side of the first sub-edge receiving portion PC11 facing the second direction Y, but this disclosure is not limited thereto, and in another embodiment, the cover glass 1000 may also be configured such that the printed layer 1200 is facing a direction opposite to the second direction Y in the first sub-edge receiving portion PC11. However, in terms of protecting the printed layer 1200, it may be more advantageous for the cover glass 1000 to be configured such that the printed layer 1200 is on the side of the first sub-edge receiving portion PC11 facing the second direction Y (which has a larger area).

[0110] When the printed layer 1200 is positioned facing the side in the second direction Y, the protective layer 1300 may be positioned close to the first sub-protrusion 212, and one surface of the glass member 1100 may be positioned close to the second sub-protrusion 213. Conversely, when the printed layer 1200 is positioned facing the direction opposite to the second direction Y, the protective layer 1300 may be positioned close to the second sub-protrusion 213, and one surface of the glass member 1100 may be positioned close to the first sub-protrusion 212.

[0111] In the first edge receiving section PC1, the width of each region can vary. The first width a1 to the sixth width a6, which will be described below, can refer to the length in the second direction Y.

[0112] The first edge receiving portion PC1 may have a first width a1 between the protruding end portion of the first sub-protrusion 212 of a first guide portion 210 and the other side surface of the first main protrusion 211 of another first guide portion 210 in the second direction Y, the other first guide portion 210 being configured to be adjacent to one side of the first guide portion 210 in the second direction Y. The first width a1 may refer to the minimum width measured in the second direction Y in the first sub-edge receiving portion PC11. Furthermore, the first width a1 may be the width in the second direction Y measured at the other side of the third sub-edge receiving portion PC13 in the first direction X.

[0113] The first edge receiving portion PC1 may have a second width a2 between the protruding end portion of the second sub-protrusion 213 of a first guide portion 210 and a side surface of the first main protrusion 211 of another first guide portion 210 in the second direction Y, the other first guide portion 210 being configured to be adjacent to the other side of the first guide portion 210 in the second direction Y. The second width a2 may refer to the minimum width measured in the second direction Y in the second sub-edge receiving portion PC12. Furthermore, the second width a2 may be the width in the second direction Y measured at one side of the third sub-edge receiving portion PC13 in the first direction X. The second width a2 may have a value substantially the same as the first width a1, but this disclosure is not limited thereto.

[0114] The first edge receiving portion PC1 may have a third width a3 in the second direction Y between the end portion of a first sub-protrusion 212 of a first guide portion 210 in a direction opposite to the first direction X and the side surface of a first main protrusion 211 of another first guide portion 210 in a direction opposite to the second direction Y, wherein the other first guide portion 210 is configured to be adjacent to the first guide portion 210 in the second direction Y. The third width a3 may refer to the maximum width of the first sub-edge receiving portion PC11 measured in the second direction Y. The third width a3 may have a value larger than each of the first width a1 and the second width a2, but this disclosure is not limited thereto.

[0115] The first edge receiving portion PC1 may have a fourth width a4 between a side end portion of a second sub-protrusion 213 of a first guide portion 210 in the first direction X and a side surface of a first main protrusion 211 of another first guide portion 210 in the second direction Y, the other first guide portion 210 being configured to be adjacent to the other side of the first guide portion 210 in the second direction Y. The fourth width a4 may refer to the maximum width measured in the second direction Y in the second sub-edge receiving portion PC12. The fourth width a4 may have a value substantially the same as the third width a3, but this disclosure is not limited thereto. Furthermore, similar to the third width a3, the fourth width a4 may have a value larger than each of the first width a1 and the second width a2.

[0116] The first edge receiving portion PC1 may have a fifth width a5 between a virtual cross-section of the protruding end portion of a first sub-protrusion 212 of a first guide portion 210 and a virtual cross-section of the protruding end portion of a second sub-protrusion 213 of another first guide portion 210, the other first guide portion 210 being configured to be adjacent to one side of the first guide portion 210 in a second direction Y. In other words, the fifth width a5 may refer to the gap in the second direction Y between the first sub-protrusions 212 and the second sub-protrusions 213 that are opposite each other. The thickness t1 of the cover glass 1000 mounted on the receiving portion RA may be at least less than or equal to the fifth width a5. The fifth width a5 may be less than each of the first widths a1 to the fourth width a4. The fifth width a5 may also be less than each of the sixth widths a6 to the eighth widths a8, which will be described below. That is, the fifth width a5 may be less than or equal to the gap measured between the first guide portions 210 that are adjacent to each other.

[0117] The tray 10 according to the embodiment can be manufactured using a mold via vacuum forming. When machining the mold used to manufacture the tray 10, a minimum machining width may exist. For example, the minimum machining width may be approximately 2.5 mm. However, by including a structure comprising a first sub-protrusion 212 and a second sub-protrusion 213 that are opposite to each other and alternately arranged, the tray 10 according to the embodiment can ensure that the fifth width a5 has a value smaller than the minimum machining width.

[0118] When the gap between the cover glass 1000 and the tray 10 is large, the cover glass 1000 may be damaged due to external impact when it is loaded onto the tray 10 for storage or transportation. Therefore, even when the cover glass 1000 loaded on the tray 10 according to the embodiment has a thickness t1 less than the minimum processing width, the cover glass 1000 can be loaded stably because no damage to the cover glass 1000 due to the gap will occur.

[0119] The first edge receiving portion PC1 may have a sixth width a6 between a virtual plane extending from the other side surface of a first main protrusion 211 of a first guide portion 210 in the second direction Y and a virtual plane extending from one side surface of a first main protrusion 211 of another first guide portion 210 in the second direction Y, the other first guide portion 210 being configured to be adjacent to the other side of the first guide portion 210 in the second direction Y. In other words, the sixth width a6 may refer to the spacing distance between the first main protrusions 211 of adjacent first guide portions 210.

[0120] The first edge receiving portion PC1 may have a seventh width a7, which is the shortest distance between the first sub-protrusion 212 and the second sub-protrusion 213. The seventh width a7 may be less than or equal to each of the first width a1 and the second width a2, but this disclosure is not limited thereto.

[0121] In the first edge receiving portion PC1, the protruding end portion of the first sub-protrusion 212 and the protruding end portion of the second sub-protrusion 213 can be spaced apart by an eighth width a8 in the first direction X.

[0122] The second edge receiving portion PC2 is the space between adjacent second guide portions 220, and can be defined by adjacent second guide portions 220 and a separating wall 400 connected to the second guide portions 220. Similar to the above-described relationship between the first guide portion 210 and the second guide portion 220, the second edge receiving portion PC2 can have a structure symmetrical with respect to the first edge receiving portion PC1 with regard to a virtual line extending in the second direction Y and dividing the first separating portion 310 disposed between the first guide portion 210 and the second guide portion 220 into two equal parts.

[0123] The second edge receiving portion PC2 may include a fourth sub-edge receiving portion PC21, which is defined in a direction opposite to the first direction X (i.e., Figure 10 The second edge receiving portion PC2 may further include a fifth sub-edge receiving portion PC22, defined in the first direction X, starting from the protruding end portion of the second main protrusion 221, and corresponding to the region extending up to the protruding end portion of the fourth sub-protrusion 223. The second edge receiving portion PC2 may also include a sixth sub-edge receiving portion PC23, defined between the fourth sub-edge receiving portion PC21 and the fifth sub-edge receiving portion PC22. In the second edge receiving portion PC2, the sixth sub-edge receiving portion PC23 may correspond to the region extending from the protruding end portion of the third sub-protrusion 222 to the protruding end portion of the fourth sub-protrusion 223 in a direction opposite to the first direction X.

[0124] The fourth sub-edge receiving part PC21 may have a structure symmetrical to the first sub-edge receiving part PC11, the fifth sub-edge receiving part PC22 may have a structure symmetrical to the second sub-edge receiving part PC12, and the sixth sub-edge receiving part PC23 may have a structure symmetrical to the third sub-edge receiving part PC13.

[0125] Therefore, since the descriptions related to the fourth sub-edge receiving section PC21, the fifth sub-edge receiving section PC22, and the sixth sub-edge receiving section PC23 are substantially the same as those related to the first sub-edge receiving section PC11, the second sub-edge receiving section PC12, and the third sub-edge receiving section PC13, except for the reverse direction, their additional descriptions will be omitted. Similarly, since the descriptions related to the first width b1 to the eighth width b8 of the second edge receiving section PC2 are also substantially the same as those related to the first width a1 to the eighth width a8 of the first edge receiving section PC1, their additional descriptions will be omitted.

[0126] The second receiving portion RA2 may have a structure symmetrical to the first receiving portion RA1 with respect to a virtual line extending in the second direction Y and dividing the separating wall 400 into two equal parts. Furthermore, the third guiding portion 230 may have a structure substantially the same as the first guiding portion 210, and may also have a structure symmetrical to the second guiding portion 220 with respect to a virtual line extending in the second direction Y and dividing the separating wall 400 into two equal parts. The fourth guiding portion 240 may have a structure substantially the same as the second guiding portion 220, and may also have a structure symmetrical to the first guiding portion 210 with respect to a virtual line extending in the second direction Y and dividing the separating wall 400 into two equal parts. The third edge receiving portion PC3 and the fourth edge receiving portion PC4 of the second receiving portion RA2 are similar to the first edge receiving portion PC1 and the second edge receiving portion PC2 of the first receiving portion RA1, and therefore their detailed description will be omitted.

[0127] Since the tray 10 according to the embodiment includes a first guide portion 210 having a first sub-protrusion 212 and a second sub-protrusion 213 that are opposite to each other and alternately arranged, and a second guide portion 220 having a third sub-protrusion 222 and a fourth sub-protrusion 223, the cover glass 1000 can be stably loaded on the tray 10 even when the thickness of the cover glass 1000 loaded on the tray 10 is small. Specifically, the gap between the guide portion 200 and the cover glass 1000 can be reduced to minimize damage to the cover glass 1000 during storage and transportation of the cover glass 1000 loaded on the tray 10.

[0128] Furthermore, the tray 10 according to the embodiment may have an edge receiving portion PC to prevent damage to the printed layer 1200 of the cover glass 1000 loaded on the tray 10.

[0129] Figure 11 It is along Figure 8 A sectional view taken by line X-X'.

[0130] refer to Figure 11The tray 10 according to the embodiment may not include an undercut structure that obstructs the removal of the product from the mold. The tray 10 can be manufactured using mold forming. For example, the tray 10 can be manufactured by vacuum forming. When separating the tray 10 from the mold during the process of manufacturing the tray 10 by vacuum forming, separation may not be easy when the tray 10 includes an undercut structure.

[0131] Specifically, the angle θ between the bottom surface of the main body portion 100 of the tray 10 and the side wall of the guide portion 200 can be greater than or equal to approximately 90 degrees (°). The angle (not shown) between the bottom surface of the main body portion 100 and the inner surface of the side wall OW, and the angle (not shown) between the bottom surface of the main body portion 100 and the side wall of the partition portion 300 can also be greater than or equal to approximately 90°. Furthermore, the internal width of the edge receiving portion PC can remain the same or can gradually increase upwards from the bottom surface of the main body portion 100.

[0132] However, this disclosure is not limited thereto, and depending on the material constituting the tray 10, it may be possible to forcibly remove the tray 10 from the mold, or when using a mold including a slide core, the angle (not shown) between the bottom surface of the main body portion 100 and the inner surface of the side wall OW, the angle (not shown) between the bottom surface of the main body portion 100 and the side wall of the partition portion 300, and the angle θ between the bottom surface of the main body portion 100 of the tray 10 and the side wall of the guide portion 200 may be less than about 90°. Furthermore, the edge receiving portion PC may include a portion in which the inner width decreases upward from the bottom surface of the main body portion 100.

[0133] In the case where the angle θ between the bottom surface of the main body portion 100 and the side wall of the guide portion 200 of the tray 10 is greater than or equal to approximately 90° and the internal width of the edge receiving portion PC remains the same or gradually increases upward from the bottom surface of the main body portion 100, the tray 10 can be easily separated from the mold during the manufacturing process because it does not include an undercut structure. Furthermore, since the tray 10 can be manufactured using a mold with a relatively simple structure, manufacturing costs can be reduced.

[0134] In the following description, a tray 10 according to another embodiment will be described. In the following description, the description of the same configuration as that described above with respect to the previous embodiment will be omitted or simplified, and the differences from the previous embodiment will be mainly described.

[0135] Figure 12 This is an enlarged view of a portion of the tray according to another embodiment.

[0136] refer to Figure 12The difference between the tray 10_1 according to this embodiment and the tray 10 according to the previous embodiment is that the tray 10_1 includes a second sub-protrusion 213_1 with a different shape.

[0137] In this embodiment, the second sub-protrusion 213_1 can be configured to protrude from the protruding end portion of the first main protrusion 211 in a direction opposite to the second direction Y. The second sub-protrusion 213_1 can have a structure in which the thickness gradually decreases from the protruding end portion of the first main protrusion 211 toward the fourth sidewall OW4. Here, the thickness of the second sub-protrusion 213_1 can refer to its thickness in the second direction Y. That is, the protruding end portion of the second sub-protrusion 213_1 can be aligned with the protruding end portion of the first main protrusion 211 in the second direction Y.

[0138] Furthermore, in the first edge receiving portion PC1_1, the second width a2_1 between the protruding end portion of the second sub-protrusion 213_1 of a first guide portion 210_1 and a side surface of the first main protrusion 211 of another first guide portion 210_1 (which is configured to be adjacent to the other side of the first guide portion 210_1 in the second direction Y) can be substantially the same as the fourth width a4_1 between the one side end portion of the second sub-protrusion 213_1 of a first guide portion 210_1 in the first direction X and a side surface of the first main protrusion 211 of another first guide portion 210_1 (which is configured to be adjacent to the other side of the first guide portion 210_1 in the second direction Y).

[0139] Furthermore, the first edge receiving portion PC1_1 may include a first sub-edge receiving portion PC11, which is defined at a position extending from the fourth sidewall OW4 in the first direction X, and corresponds to the region extending up to the protruding end portion of the first sub-protrusion 212. The first edge receiving portion PC1_1 may also include a second sub-edge receiving portion PC12_1, which is defined at a position extending from the protruding end portion of the second sub-protrusion 213_1 in a direction opposite to the first direction X, and corresponds to the region extending up to the protruding end portion of the first sub-protrusion 212.

[0140] Since the tray 10_1 according to this embodiment includes a first guide portion 210_1 having a first sub-protrusion 212 and a second sub-protrusion 213_1 that are opposite to each other and alternately arranged, the cover glass 1000 can be stably loaded on the tray 10_1 even when the thickness of the cover glass 1000 loaded on the tray 10_1 is small. Specifically, the gap between the guide portion 200 and the cover glass 1000 can be reduced to minimize damage to the cover glass 1000 during storage and transportation of the cover glass 1000 loaded on the tray 10_1.

[0141] Furthermore, the tray 10_1 according to this embodiment may have an edge receiving portion PC to prevent damage to the printed layer 1200 of the cover glass 1000 loaded on the tray 10_1.

[0142] Furthermore, since the tray 10_1 according to this embodiment includes a second sub-protrusion 213_1 whose protruding end portion is aligned with the protruding end portion of the first main protrusion 211, the space for loading the cover glass 1000 can be adjusted more easily. That is, since the second sub-protrusion 213_1 is further disposed inwardly within the tray 10_1, the mold for manufacturing the tray 10_1 can be conveniently designed.

[0143] Figure 13 This is an enlarged view of a portion of the tray according to yet another embodiment.

[0144] refer to Figure 13 The difference between the tray 10_2 according to this embodiment and the tray 10 according to the previous embodiment is that the tray 10_2 includes a first sub-protrusion 212_2 with a different shape.

[0145] In this embodiment, the thickness of the first sub-protrusion 212_2 on one side (i.e., the left side) in the direction opposite to the first direction X can be greater than the thickness of the first sub-protrusion 212_2 on the other side (i.e., the right side) in the first direction X. Here, the thickness of the first sub-protrusion 212_2 can refer to the thickness in the second direction Y.

[0146] Therefore, compared to the side surface of the first main protrusion 211 on one side in the second direction Y, the side end portion of the first sub-protrusion 212_2 in the direction opposite to the first direction X can have a more concave shape in the direction opposite to the second direction Y.

[0147] In the first edge receiving portion PC1_2, the third width a3_2 in the second direction Y between the end portion of the first sub-protrusion 212_2 of a first guide portion 210_2 in the direction opposite to the first direction X and the side surface of the first main protrusion 211 of another first guide portion 210_2 (which is configured to be adjacent to the first guide portion 210_2 in the second direction Y) in the direction opposite to the second direction Y can be greater than the fourth width a4 in the second direction Y between the side end portion of the second sub-protrusion 213 of a first guide portion 210_2 in the first direction X and the side surface of the first main protrusion 211 of another first guide portion 210_2 (which is configured to be adjacent to the first guide portion 210_2 in the direction opposite to the second direction Y).

[0148] Furthermore, in this embodiment, the first edge receiving portion PC1_2 may include a first sub-edge receiving portion PC11_2, which is defined at a position starting from the fourth sidewall OW4 in the first direction X, and corresponds to the region extending up to the protruding end portion of the first sub-protrusion 212_2. The first edge receiving portion PC1_2 may also include a second sub-edge receiving portion PC12, which is defined at a position starting from the protruding end portion of the first main protrusion 211 in a direction opposite to the first direction X, and corresponds to the region extending up to the protruding end portion of the second sub-protrusion 213. The first edge receiving portion PC1_2 may also include a third sub-edge receiving portion PC13 defined between the first sub-edge receiving portion PC11_2 and the second sub-edge receiving portion PC12. The third sub-edge receiving portion PC13 may correspond to the region in the first edge receiving portion PC1_2 extending from the protruding end portion of the first sub-protrusion 212_2 to the protruding end portion of the second sub-protrusion 213 in the first direction X.

[0149] The first sub-edge receiving portion PC11_2 may include a space wider than each of the second sub-edge receiving portion PC12 and the third sub-edge receiving portion PC13. Therefore, when the cover glass 1000 is loaded on the tray 10_2, the printed layer 1200 disposed on the first sub-edge receiving portion PC11_2 can be protected more effectively.

[0150] Since the tray 10_2 according to this embodiment includes a first guide portion 210_2 having a first sub-protrusion 212_2 and a second sub-protrusion 213 that are opposite to each other and alternately arranged, the cover glass 1000 can be stably loaded on the tray 10_2 even when the thickness of the cover glass 1000 loaded on the tray 10_2 is small. Specifically, the gap between the guide portion 200 and the cover glass 1000 can be reduced to minimize damage to the cover glass 1000 during storage and transportation of the cover glass 1000 loaded on the tray 10_2.

[0151] Furthermore, the tray 10_2 according to this embodiment may have an edge receiving portion PC to prevent damage to the printed layer 1200 of the cover glass 1000 loaded on the tray 10_2.

[0152] Furthermore, since the tray 10_2 according to this embodiment has a first sub-edge receiving portion PC11_2 including a wider space, the printed layer 1200 disposed on the first sub-edge receiving portion PC11_2 can be protected more effectively when the cover glass 1000 is loaded on the tray 10_2. For example, the tray 10_2 according to this embodiment can effectively protect the printed layer 1200 regardless of whether the printed layer 1200 is oriented towards the second direction Y or towards a direction opposite to the second direction Y.

[0153] Figure 14 This is an enlarged view of a portion of the tray according to another embodiment.

[0154] refer to Figure 14 The tray 10_3 according to this embodiment differs from the tray 10 according to the previous embodiment in that the tray 10_3 includes a first sub-protrusion 212_3 with a different shape. The first sub-protrusion 212_3 may have a shape in which its thickness in the second direction Y increases and then decreases in the first direction X. The first sub-protrusion 212_3 may have a structure symmetrical about a virtual line extending through the protruding end portion of the first sub-protrusion 212_3 and in the second direction Y.

[0155] Therefore, the area between the fourth sidewall OW4 and the other end of the first sub-protrusion 212_3 in the first direction X can be aligned with one side surface of the first main protrusion 211 in the second direction Y.

[0156] In the first edge receiving portion PC1_3, the third width a3_3 in the second direction Y between the end portion of the first sub-protrusion 212_3 of a first guide portion 210_3 in the direction opposite to the first direction X and the side surface of the first main protrusion 211 of another first guide portion 210_3 (which is configured to be adjacent to the first guide portion 210_3 in the second direction Y) in the direction opposite to the second direction Y can be substantially the same as the sixth width a6 in the second direction Y between the virtual plane extending from the side surface of the first main protrusion 211 of the first guide portion 210_3 in the direction opposite to the second direction Y and the virtual plane extending from the side surface of the first main protrusion 211 of the other first guide portion 210_3 (which is configured to be adjacent to the first guide portion 210_3 in the direction opposite to the second direction Y).

[0157] Furthermore, in this embodiment, the first edge receiving portion PC1_3 may include a first sub-edge receiving portion PC11_3, which is defined at a position starting from the fourth sidewall OW4 in the first direction X, and corresponds to the region extending up to the protruding end portion of the first sub-protrusion 212_3. The first edge receiving portion PC1_3 may also include a second sub-edge receiving portion PC12, which is defined at a position starting from the protruding end portion of the first main protrusion 211 in a direction opposite to the first direction X, and corresponds to the region extending up to the protruding end portion of the second sub-protrusion 213. The first edge receiving portion PC1_3 may also include a third sub-edge receiving portion PC13 defined between the first sub-edge receiving portion PC11_3 and the second sub-edge receiving portion PC12. The third sub-edge receiving portion PC13 may correspond to the region in the first edge receiving portion PC1_3 extending from the protruding end portion of the first sub-protrusion 212_3 to the protruding end portion of the second sub-protrusion 213 in the first direction X.

[0158] The first sub-edge receiving portion PC11_3 may include a space wider than each of the second sub-edge receiving portion PC12 and the third sub-edge receiving portion PC13. Therefore, when the cover glass 1000 is loaded on the tray 10_3, the printed layer 1200 disposed on the first sub-edge receiving portion PC11_3 can be protected more effectively.

[0159] Since the tray 10_3 according to this embodiment includes a first guide portion 210_3 having a first sub-protrusion 212_3 and a second sub-protrusion 213 that are opposite to each other and alternately arranged, the cover glass 1000 can be stably loaded on the tray 10_3 even when the thickness of the cover glass 1000 loaded on the tray 10_3 is small. Specifically, the gap between the guide portion 200 and the cover glass 1000 can be reduced to minimize damage to the cover glass 1000 during storage and transportation of the cover glass 1000 loaded on the tray 10_3.

[0160] Furthermore, the tray 10_3 according to this embodiment may have an edge receiving portion PC to prevent damage to the printed layer 1200 of the cover glass 1000 loaded on the tray 10_3.

[0161] Furthermore, since the tray 10_3 according to this embodiment has a first sub-edge receiving portion PC11_3 including a wider space, the printed layer 1200 disposed on the first sub-edge receiving portion PC11_3 can be protected more effectively when the cover glass 1000 is loaded on the tray 10_3. For example, the tray 10_3 according to this embodiment can effectively protect the printed layer 1200 regardless of whether the printed layer 1200 is disposed facing the second direction Y or facing a direction opposite to the second direction Y.

[0162] Figure 15 This is an enlarged view of a portion of the tray according to another embodiment.

[0163] refer to Figure 15 The difference between the tray 10_4 according to this embodiment and the tray 10 according to the previous embodiment is that the first edge receiving portion PC1_4 and the second edge receiving portion PC2_4 are point-symmetric to each other in the plan view about the midpoint of the first central receiving portion CR1.

[0164] In the tray 10_4 according to this embodiment, as described above, since the first edge receiving portion PC1_4 and the second edge receiving portion PC2_4 are point-symmetric to each other, the space in which the cover glass 1000 can partially rotate while being loaded onto the tray 10_4 can be provided to be larger than the space in the tray 10 according to the previous embodiment. Therefore, it is easier to load the cover glass 1000 onto the tray 10_4 or to detach the cover glass 1000 from the tray 10_4.

[0165] Since the tray 10_4 according to this embodiment includes a first guide portion 210_4 having first and second sub-protrusions that are opposite to each other and alternately arranged, the cover glass 1000 can be stably loaded onto the tray 10_4 even when the thickness of the cover glass 1000 loaded on the tray 10_4 is small. Specifically, the gap between the guide portion 200 and the cover glass 1000 can be reduced to minimize damage to the cover glass 1000 during storage and transportation of the cover glass 1000 loaded on the tray 10_4.

[0166] Furthermore, the tray 10_4 according to this embodiment may have an edge receiving portion PC_4 to prevent damage to the printed layer 1200 of the cover glass 1000 loaded on the tray 10_4.

[0167] Furthermore, since the tray 10_4 according to this embodiment includes a first edge receiving portion PC1_4 and a second edge receiving portion PC2_4 that are point-symmetric to each other about the midpoint of the first central receiving portion CR1 in a plan view, the process of loading the cover glass 1000 onto the tray 10_4 or separating the cover glass 1000 from the tray 10_4 can be easily performed.

[0168] According to one embodiment, the tray allows for stable loading of the cover glass by means of multiple guide portions arranged alternately and including protruding shapes. Furthermore, the tray includes an edge receiving portion separately disposed on one side of the guide portions to prevent damage to the printed layer formed on the cover glass.

[0169] The beneficial effects of the embodiments are not limited to those described above, and various other beneficial effects are included herein.

[0170] In concluding this detailed description, those skilled in the art will understand that many variations and modifications can be made to the preferred embodiments without substantially departing from the principles of the invention. Therefore, the preferred embodiments disclosed herein are used only in a general and descriptive sense and not for limiting purposes.
