A shock-absorbing subsidiary materials for packaging Plasma Display Panel}

The present invention relates to a shock absorbing member for packaging a finished product PDID, and more particularly to a shock absorbing member for packing a finished product PDIP for transporting the finished product using the plasma display panel to the destination.

PDP, which is commercialized in recent years, is a cutting-edge video equipment that plays the role of DTV, HDTV, and PC monitor as well as general TV viewing, and is currently being developed for liquid crystal display (LCD), field emission display (FED), and electro luminescence display (ELD). Among flat panel displays in the same field, it is suitable for large-sized display, and high quality is maintained even at about 60 ″.

The reason why PDP can be enlarged with a flat plate is to apply a suitable electrode and phosphor to each of two glass substrates, each of which is about 3 mm thick, and to form a plasma in the space between them by keeping an interval of about 0.1 to 0.2 mm. Because it is the way. At the production site, some of these PDPs are shipped as semi-finished products to other assembly producers, while others are combined with various types of cabinets as finished products to end users.

However, considering that the PDP is still expensive, the packaging method that can completely protect it from external shocks without increasing the transportation cost in the process of shipping the finished product after shipment is urgently needed.

Accordingly, an object of the present invention is to provide a shock absorbing member for packing a finished product of PDPD for safely transporting the finished product using the plasma display panel to the destination without any damage.

1 through 5, the present invention proposes three exemplary embodiments related to the cushioning member for packaging a PDP finished product, and has a side end block 10 having ribs 12, 32, 42 on its outer surface. (30) and (40) have a common structure in that they are inserted into and inserted into the corner portions of the finished PDP product. In addition to this, boxes 60 and 62 having a vertical dividing structure for accommodating the finished PDP together with the blocks are used (to be described later in FIG. 6).

1 and 4, it is also possible to further include a central block 20, 50 to be inserted into and removed from the edge of the finished PDP product. 1 and 3, the side end blocks 10 and 30 further include uneven grooves 11 and 31 in close contact with the front and rear sides of the product, and side end grooves 15 and 35 spaced apart from the side ends of the product. It is also possible. This configuration will be described for each embodiment in the order of the drawings.

In the embodiment of the present invention, all blocks are injection molded from expanded polypropylene (EPP) or a material having similar properties (EPE, EPS, Hanaseran, etc.). In addition, if various colors such as red, blue, green, and yellow are added according to the formulation of the pigment, it is easy to distinguish the model of the product or the date of manufacture.

First, in Figure 1, the side end of the side block 10 is provided with ribs 12 in three places and the upper surface has a four-stage structure including the uneven groove 11, the open end 13, the support end (14). The rib 12 preferably protrudes sufficiently for stable support, and the number of the ribs 12 is not limited to three, but may be appropriately provided. The height difference between the uneven groove 11 and the open end 13 is such that the glass G of the PDP finished product is not in contact with each other, and the height difference between the uneven groove 11 and the support end 14 is in contact with the rear surface of the PDP finished product. It is to be measured. The uneven groove 11 is staggered staggered form extending in the vertical downward direction from the open end 13 and the support end 14. The side end groove 15 spaced apart from the side end of the product in the side block 10 is in communication with the uneven groove (11). The side end groove 15 is semicircular in plan view and is symmetrically formed in the front and rear directions to prevent breakage by elastic deformation when an impact is applied at the side end.

In the first embodiment, two side end blocks 10 and one central block 20 are used to support the lower end of the PDP finished product. Similar to the side block 10, the central block 20 also has ribs 22 on the outer surface and uneven grooves 21, open ends 23, and support ends 24 on the upper surface thereof, particularly uneven grooves 21, In the open end 23 and the support end 24, the sameness of dimensions is required. However, the same as the side groove 15 of the side block 10 is excluded in the central block (20).

At this time, the side block 10 has a stepped 12a cut in the letter L at the upper end of the rib 12 in front. The rib 12 in front of the side block 10 has the same height as the open end 13 and at least one of the ribs 12 (preferably the central portion) has a stepped portion 12a which acts on the finished PDP product. Relieve external shocks. The step 22a of the central block 20 has the same in size and function as the step 12a of the side end block 10.

In Fig. 2, reference numeral 16 on the bottom of the side block 10 is a groove formed for weight loss, and 18 is a trace of the pusher and feeders. The groove 16 is formed in a shape and a dimension in which the thickness difference of the material is evenly maintained in connection with the ribs 12 on the three sides, thereby preventing defects in the injection process and increasing strength.

In the second embodiment of FIG. 3, two side end blocks 30 are used and a structure is not provided in the center. This is a form for transporting a smaller and lighter PDP finished product, which has the same uneven groove 31 and an outer rib 32 as compared with FIG. 1, but does not have an open end 13 and a support end. 14 is formed at a small height at the bottom of the uneven groove 31. The ribs 32 may be formed in various shapes at different heights. Although there is no open end 13, it is in contact with the glass (G) of the PDP finished product, but almost no problem was found in the impact test results. The side end groove 35 supporting the side surface of the PDP finished product has a shape smaller than that of the side end groove 15 of FIG. 1, as if it is an extension of the uneven groove 31. The side end groove 35 prevents breakage of the side end block 30 by appropriately allowing elastic deformation when an external impact is applied.

At this time, the side end block 30 is provided with a through hole 36 and a cutting groove 38 on the bottom of the uneven groove 31. The through hole 36 formed in the bottom surface of the uneven groove 31 in the side end block 30 on one side vertically penetrates downwardly of the uneven groove 31 to perform a function of a power point through which the wire of the finished PDP product is passed. do. Incision groove 38 formed on the bottom surface of the uneven groove 31 in the side end block 30 on both sides induces a smooth coupling according to the cabinet shape of the finished PDP.

The bottom structure of FIG. 3 does not differ greatly in that the recess 16 is provided as in FIG. 2, but the protrusion pieces may be added in only two places. If the bottom surface of the packaging box is formed to engage with the same position and size of the projection pieces to facilitate engagement is less shaking of the side block 30 in the process of inserting the finished PDP product.

In the third embodiment of FIG. 4, the left and right two side end blocks 40 and the side end blocks 40 each having ribs 42 and 52 on the outer surface for supporting the lower end of the PDP finished product are placed in the middle. Losing one central block 50 is used. Compared with the previous embodiments, although the open end 43, the support end 44, and the side end groove 45 are provided, the shape is slightly different, and the above-mentioned uneven grooves 11 and 31 are excluded and are in a planar state. It is in contact with the PDP finished product. The open end 43 is a plane of height not in contact with the glass G of the product P, while the support end 44 is formed with an inclined surface coincident with the cabinet behind the product P. The side end groove 45 is in close contact with the product. This is a structure in which the foaming ratio of the material is increased to increase the strength instead of the simple form compared with the first and second embodiments described above. The structure of the ribs 42 and 52 is simplified and reduced in size. The central block 50 has the same identity as the side block 40 in the dimensions of the open end 53 and the support end 54. The rib 52 in front of the central block 50 lowers the height for the same purpose as the step 12a, 22a of FIG.

At this time, the side end block 40 is provided with a protrusion (42a) protruding horizontally on the upper end from the front rib (42). The protrusion 42a protrudes forward from the side end blocks 40 on both sides and covers the lower box 60 but is not formed in the central block 50. The operation of the protrusion 42a is described in detail later with reference to FIG. 6.

On the other hand, as can be seen through the embodiment of the present invention, each block consisting of two or three parts may be formed separately, but each block is molded integrally by thinning the flesh of the parts connected to each other, and in actual use Each block can be separated and used as needed.

6 is a schematic view showing a state of use of the buffer member according to the present invention.

The present invention uses a lower height box 60 and a high height upper box (62) (64). The lower box 60 is convenient to put the product in a state supporting the block if the height similar to the block. In FIG. 6a, the lower box 60 is placed on the floor, and the side end block 10 and the center block 20 are inserted, and then the product is inserted. The lower box 60 prevents the central block 20 from being pushed out when the product is inserted. Subsequently, the side block 10 and the central block 20 are inserted into the upper side of the product, and then the upper box 62 is covered from the top and sealed, and the plurality of bands 66 are bound to the outside. In FIG. 6B, the packing using the lower box 60, the side end block 10, the center block 20, and the upper box 64 is the same, but the band 66 may be excluded. In FIG. 6B, the upper box 64 has a higher strength than the upper box 62 of FIG. 6A and may include other fastening means such as bolts and clamps.

In the third embodiment of the present invention (FIGS. 4 and 5), the protrusion 42a on the rib 42 is caught on the upper end of the lower box 60 to prevent the shaking during packing or transportation. Since the upper boxes 62 and 64 have high heights, the protrusion 42a is omitted in the side end block 40 coupled to the upper end of the product.

Although not shown, all the blocks of the embodiment according to the present invention may be provided with a chamber (Chamber) in the corner portion contacted when the product is inserted in addition to the uneven groove (11, 21, 31). The chamber can be molded integrally during injection and prevents breakage by mitigating impact when the product is inserted into place. In the present invention, because the product is mounted vertically downward to the block, the chamber at the edge of the horizontal plane than the vertical plane exhibits a more useful function.

On the other hand, PDP is generally divided into AC type and DC type, and AC type is divided into counter discharge type and surface discharge type again. Such DC type and AC type have different structure for current limiting, In terms of form, there is no difference in application.

According to the above configuration and operation, the present invention has a useful effect that can safely transport the finished product using the plasma display panel to the destination without any damage.
