The present invention relates to a packaging container, and more particularly to a packaging container for a liquid crystal panel.

Recently, with the development of various portable electronic devices such as mobile phones, PDAs, and notebook computers, there is an increasing demand for flat panel display devices for light and thin applications. Such flat panel displays are being actively researched, such as LCD (Liquid Crystal Display), PDP (Plasma Display Panel), FED (Field Emission Display), VFD (Vacuum Fluorescent Display), but mass production technology, ease of driving means, Liquid crystal display devices (LCDs) are in the spotlight for reasons of implementation.

1 is a schematic cross-sectional view of a general liquid crystal display panel. As shown in the figure, the liquid crystal display device 1 is composed of a lower substrate 5 and an upper substrate 3 and a liquid crystal layer 7 formed between the lower substrate 5 and the upper substrate 3. . Although the lower substrate 5 is a driving element array substrate, although not shown in the drawing, a plurality of pixels are formed on the lower substrate 5, and each pixel is driven such as a thin film transistor. An element is formed. The upper substrate 3 is a color filter substrate, and a color filter layer for realizing color and a black matrix for blocking light leakage are formed. In addition, a pixel electrode and a common electrode are formed on the lower substrate 5 and the upper substrate 3, respectively, and an alignment film (not shown) for aligning liquid crystal molecules of the liquid crystal layer 7 is coated.

The lower substrate 5 and the upper substrate 3 are bonded by a sealing material 9, and a liquid crystal layer 7 is formed therebetween so that the liquid crystal is driven by a driving element formed on the lower substrate 5. The information is displayed by driving the molecules to control the amount of light passing through the liquid crystal layer.

In the liquid crystal display panel configured as described above, a plurality of unit liquid crystal display panels are formed on a large mother substrate and completed through a cutting process. The completed liquid crystal display panel is finally packaged and shipped through a test process. Since the liquid crystal display panel includes elements sensitive to static electricity, the liquid crystal display panel is packaged and stored in a special packaging container that can block static electricity.

In general, a packaging container is used to store, store and transport electronic components such as a liquid crystal panel. The packaging container covers a housing portion having a plurality of slots and an upper portion of the housing portion for storing electronic components. It consists of wealth. At this time, by narrowing the distance between the slots, the storage efficiency of the panel can be increased.

The cover part is manufactured by vacuum forming, and when the distance between slots is narrowed, a problem arises that an unmolded area is generated, and particularly, such a problem occurs in the edge area.

Figure 2 shows a part of the cover for explaining the conventional problem.

As shown in the figure, the lid portion 10 of the conventional packaging container is formed with a plurality of partition walls 13 for isolating the liquid crystal panel individually, grooves 15 are provided between the partition walls (13). The liquid crystal panel is configured to be fitted.

By the way, as the space | interval of the partition 13 is reduced in order to increase the capacity | capacitance (charging efficiency) of a liquid crystal panel, the problem which shaping | molding does not occur in the inclined area | region A of the side part of a cover part arises. That is, the cover part is made by vacuum forming, which forms a product such as the formation of a mold by vacuum in a state of ductility by applying heat to a raw material sheet, wherein the width of the partition wall 13 is 10 mm or less. Increasingly, the shaping of the inclined area is not performed properly, so that an unmolded area is generated, or the width of the sheet becomes thin, thereby causing a problem such as a hole or a decrease in strength. Therefore, the conventional packaging container has a limit in increasing the charging efficiency.

Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to provide a packaging container which can increase the charging efficiency of the liquid crystal panel.

Another object of the present invention is to provide a packaging container capable of preventing unmolding and molding failure.

Packaging container of the present invention for achieving the above object is a bottom portion provided with a liquid crystal panel accommodating groove; First and second side portions vertically oriented with respect to the bottom portion, the upper surfaces of which are inclined, and which face each other; A cover portion covering the bottom surface portion, having a plurality of partition walls for separating the liquid crystal panel separately and grooves for accommodating the liquid crystal panel between the partition walls and both sides thereof with an inclined surface in contact with upper surfaces of the first and second side surface portions. And a groove for connecting two grooves adjacent to each other on an inclined surface of the cover part.

A plurality of slots are provided inside the first and second side parts to fit both sides of the liquid crystal panel, and further include third and fourth side parts facing each other on the front and rear surfaces of the bottom part.

In this case, the third and fourth side portions are integrally formed with the lid portion, and the third and fourth side portions are configured to be folded at right angles from the lid portion, or the third and fourth side portions are the lid portion. It can be configured separately from the part.

 The contact surface of the bottom portion and the first and second side portions has an inclined surface.

The liquid crystal panel container of the present invention configured as described above forms grooves for connecting the liquid crystal panel accommodating grooves on the inclined surfaces of the lid portions in contact with the first and second side portions, thereby preventing molding defects on the inclined surfaces of the lid portions, Can improve the charging efficiency.

In other words, in the past, in order to increase the charging efficiency of the liquid crystal panel, in the process of reducing the width of the partition wall, defective molding of the inclined surface in contact with the side portion occurred, but the present invention allows the two liquid crystal panel accommodating grooves to be connected at the inclined surface. That is, by forming a groove connecting the two liquid crystal panel accommodating grooves on the inclined surface, solving the problem of molding failure of the packaging container, and also improves the charging efficiency.

Hereinafter, the liquid crystal panel packaging container according to the present invention will be described in more detail with reference to the accompanying drawings.

3 schematically shows a packaging container for a liquid crystal panel according to the present invention. In particular, the cover part and the bottom part / side part are separated.

As shown in the figure, the liquid crystal panel packaging container 100 according to the present invention is formed with a plurality of partitions 113, the bottom portion 110 to accommodate the liquid crystal panel 130, and the bottom portion 110 And a liquid crystal panel formed integrally with the first and second side portions 120A and 120B facing each other and in contact with the top surfaces of the first and second side portions 120A and 120B and accommodated in the bottom portion 110. The cover unit 150 covers the 130.

 Grooves 115 are formed between the partition walls 113 by the partition walls 113 arranged at regular intervals on the bottom portion 110, and the liquid crystal panel 130 is accommodated in the grooves 115.

Meanwhile, a plurality of slots 123 are provided in the inner side of the first and second side parts 120A and 120B to allow the side surfaces of the liquid crystal panel 130 to be fitted, respectively, to effectively prevent the liquid crystal panel 130 from bending. . In addition, the first and second side parts 120A and 120B are configured to be folded inward with respect to the bottom part 110, and the bottom part (B) in a state where the first and second side parts 120A and 120B are folded. 110 and the first and second side portions 120A and 120B form a right angle.

At this time, the first and second side portion (120A, 120B) is folded to form a slope so as to be structurally folded. That is, the first and second side surfaces 120A and 120B and the bottom surface 110 are in contact with each of the inclined surfaces 121, and the first and second side surfaces coming into contact with the cover part 150. Top surfaces of 120A and 120B also have inclined surfaces 121.

4A schematically illustrates a state in which the first and second side parts are connected to the bottom part 110 before the first and second side parts are folded, and detailed configurations of the partition and the slot are omitted.

As shown in the figure, first and second side portions 120A and 120B are provided at both sides of the bottom portion 110, and inclined surfaces 122 are formed on the connecting surfaces thereof.

3 and 4, the front and rear surfaces of the packaging container in which the liquid crystal panel 130 is accommodated are configured to be integral with the cover part 150, and the third and fourth side parts 140A and 140B. The third and fourth side parts 140A and 140B may be separated from the cover part 150 to be separately configured. However, when integrally formed with the cover part 150, the contact surface with the cover surface must form an inclined surface so that the third and fourth side parts 140A and 140B can be folded at right angles. 4B is a view showing that the side surface of the cover part 150 in contact with the first and second side parts is formed as an inclined surface.

In addition, when the third and fourth side parts 140A and 140B are integrally formed with the cover part 150, the liquid crystal panel 130 may be stored in a packaging container, and then the packaging time may be shortened. have. That is, when the third and fourth side parts 140A and 140B are connected to the cover part 150, the packaging may be completed by covering the cover part on the upper portion of the liquid crystal panel 130. When the 140B) is configured to be separated from the cover part, the third and fourth side parts 140A and 140B need to be separately inserted into the front and rear surfaces of the packaging container, thereby increasing the packaging time.

However, in the present invention, the configuration of the third and fourth side parts is not limited to a specific form, and the third and fourth side parts 140A and 140B are integrally formed with the cover part 150 or separately separated from each other. Includes all configured packaging.

The packaging container 100 configured as described above uses PE (polyethylene), PP (polypropylene), PET (polyethylene terephthalate), PS (polystyrene), etc., to protect the liquid crystal panel 130 from static electricity and to resist external shocks. do.

Meanwhile, an insertion groove into which the liquid crystal panel is inserted is formed in the cover part 150 by a plurality of partitions. In particular, grooves connecting two liquid crystal panel insertion grooves are formed on both inclined surfaces.

5 shows the cover part of the present invention in detail, and shows the inside of the cover part into which the liquid crystal panel is directly inserted.

As shown in the figure, the cover portion 150 of the packaging container according to the present invention is formed with a plurality of partitions 153 forming the liquid crystal panel insertion groove 155, the partition 153 is formed on both sides thereof It has an inclined surface 151. This is to ensure there is no gap in engagement with the side portion, as described above.

In addition, in the present invention, the liquid crystal panel insertion grooves 155 adjacent to each other with the partition wall 153 interposed therebetween are connected to each other, and in particular, are connected through the connection groove 160 formed on the inclined surface 151. That is, connecting grooves 160 are formed at both sides of the inclined surface 151 to connect neighboring insertion grooves 155 into one, and the connection grooves 160 may reduce the width D ′ of the partition wall 153. As a result, the charging efficiency of the liquid crystal panel is improved.

In more detail, the partition wall 153 is for separating the liquid crystal panels 130 individually, and the narrower the width, the more the charging efficiency for storing the liquid crystal panel inside the predetermined packaging container increases. . However, as mentioned in the prior art, when the width of the partition wall 153 is narrowed to 10 mm or less, problems such as unmolding of an insertion groove in the inclined surface, holes in the inclined surface, and a decrease in strength occur. Will occur. These problems occur because as the width of the partition wall 153 decreases, the sheet becomes thin due to an increase in the number of partition walls, and by minimizing the thinning of the sheet, these problems can be solved.

Therefore, in the present invention, the connecting groove 160 for connecting two neighboring insertion grooves 155 into one with the partition wall 153 therebetween is additionally formed on the inclined surface. In this case, the connecting groove 160 formed on the inclined surface 151 minimizes the sheet bending on the inclined surface 151 to minimize the thinning of the sheet. That is, as in the related art, when the insertion grooves 155 are formed independently, the same number of insertion grooves as the liquid crystal panel to be accommodated are formed on the inclined surface. However, when two insertion grooves are connected to one, the number of grooves on the inclined surface is reduced by half, and the degree of bending of the sheet is reduced, thereby minimizing the thinning of the sheet.

As described above, the present invention relates to a packaging container for a liquid crystal panel, and the basic concept of the present invention is to connect a liquid crystal panel insertion groove adjacent to an inclined surface of the cover portion covering the upper portion of the liquid crystal panel, that is, the surface in contact with the side portion. To form a connecting groove.

As described above, the present invention further forms grooves for connecting the liquid crystal panel insertion grooves on the inclined surface of the cover part, thereby preventing molding defects and reducing the width of the partition wall to 10 mm to improve the charging efficiency of the liquid crystal panel.

As described above, the present invention is formed in the liquid crystal panel packaging container on both sides of the cover portion, that is, the surface in contact with the side portion as an inclined surface, and further formed grooves for connecting the liquid crystal panel receiving groove formed inside the cover portion to the inclined surface. By this, the charging efficiency of the liquid crystal panel is further improved.

In addition, according to the present invention, by adding a groove connecting the liquid crystal panel accommodating groove, it is possible to reduce the material cost by preventing the molding failure of the cover portion.
