Description

Shock absorbing box for thin panel {Shock absorbing box for thin panel}

The present invention relates to a cushioning box for panel products, and more particularly, a panel that can be used semi-permanently and repeatedly while semi-permanently protecting from external impact when packing a plate-shaped finished product or intermediate product such as TFT-LCD. A buffer box for a product.

TFT-LCD has a panel in which liquid crystal is injected between two glass substrates, a driving circuit with various circuit elements such as a driver for driving the panel, and a backlight which maintains brightness by using a light source. It consists of a chassis structure such as (Backlight). However, in the actual industrial field is often transported in a semi-finished (middle product) state before being modularized as described above, the packaging method as shown in Figure 1 is applied for the safe transport of such expensive goods.

1 is a configuration diagram showing a conventional buffer box, which is disclosed in Korean Utility Model Registration No. 20-0229096.

That is, when the side buffer 14 is connected to both sides of the planar buffer 12 and folded in a U-shape, the upper and front and rear sides are completed in an open box, and the top buffer 16 at the upper end of the side buffer 14, respectively. The top cover is completed when is folded in the form of an "-". Each of the buffer members 12, 14 and 16 has ribs 12a, 14a and 16a on the outer surface to absorb shocks, and fixing ribs 14b are formed on the inner surface of the side buffer 14. Support panel products.

Typically, corrugated paper or pulp mold is used as a material of the conventional buffer box. In the latter case, a pulp solution obtained by decomposing waste paper or pure pulp in water is vacuum-dried and molded into a mold (mould), followed by dry recycled paper.

However, when a paper material such as corrugated paper or pulp mold is used, the strength is weak, and thus the role of the cushioning material is insufficient, and it is difficult to be repeatedly used due to the easy deformation by the environment such as humidity. In the structure of bonding and finishing, the bonding part is easy to fall during transportation or storage, so there is a high possibility that the product will be damaged due to the loss of the buffer function.

In particular, in the structure as shown in Figure 1, each of the buffer material 12, 14, 16 is connected to the V-shaped groove so that the connection portion is folded well, and after repeated use, the damage starts to occur in this portion first. In addition, the fixing rib 14b is also weak in strength, there is a closed end that is limited to be applied to long-distance transportation of medium and large panel products.

Accordingly, the present invention has been devised in view of the above, and when packaging a finished product or intermediate product such as a TFT-LCD, it is possible to repeatedly use it semi-permanently while protecting it from external impacts, thereby reducing the logistics cost. It is an object to provide a buffer box.

27: U groove 28, 29: groove

30: cover 33, 34: locking jaw

In order to achieve this object, the present invention provides a cushioning box for accommodating a plurality of panel products P by using at least three partition walls 21 and 22: a hook having an uneven shape at an upper end bent to three sides. A main body 20 having grooves 23 and 24 and absorbing shocks by ribs 25 and 26 and grooves 28 and 29 on the outer surface; And a locking jaw 33 and 34 having a cross-section so as to be coupled to the locking grooves 23 and 24 of the main body 20, respectively, and the cover 30 absorbing the impact by the ribs 36 on the upper surface. Characterized in that comprises a.

The main body 20 of the present invention is provided with a U-shaped groove 27 in the entire length of the bent portion, the U-shaped groove 27 is reinforced with a plurality of circular ribs (27a).

The ribs 25 and 26 of the body 20 and the ribs 36 of the cover 30 according to the present invention are formed in an uneven shape so that the thickness thereof varies.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment according to the present invention.

Figure 2 is a perspective view showing the separation of the buffer box according to the present invention, Figure 3 is a block diagram showing the development of the buffer box according to the present invention, Figure 4 is a plan view showing the assembled state of the buffer box according to the present invention. .

The present invention relates to a buffer box for accommodating a plurality of panel products (P) using at least three partition walls (21, 22), applying a foamed resin material to compensate for the disadvantages of conventional paper materials do. As a foamed resin material, non-crosslinked EPE (LLDPE) and Expanded Polypropylene (EPP) are generally excellent in cushioning, flexibility, and chemical resistance, resulting in improved packaging stability and smaller packaging volume. Normally, EPE is relatively soft and is used in light weight products, while EPP is relatively hard and has a breaking property, but high strength. In the present invention, it is also preferable to use EPP of strength that can replace plastic.

In forming the box form consisting of the main body 20 and the cover 30 in the present invention, if EPP or equivalent materials are used, not only the physical properties such as impact resistance and water resistance, but also formability and dimensional stability are good and economical, as compared to paper materials. Secured.

The main body 20 according to the present invention is provided with locking grooves 23 and 24 having an uneven shape at an upper end that is bent into three surfaces, and by ribs 25 and 26 and grooves 28 and 29 of the outer surface. Absorb the shock. The main body 20 has a structure that can be folded into three surfaces, and partition walls 21 and 22 are formed on each inner surface. The size of the partitions 21 and 22 is adjusted according to the size of the panel product P, but it is advantageous in terms of ease of packaging to have a length for free space on the upper and lower sides. The locking groove 23 on one side has a concave center, and the locking groove 24 on the other side has a convex center. In each of the engaging grooves 23 and 24, the concave and convex portions are not meshed with each other but have the same dimensions. Of the three-face member of the main body 20, the member standing upright is provided with grooves 28 and 29, the groove 28 on one side is formed in the corner portion and the other groove 29 on the outer flat portion Form. The grooves 28 and 29 are elastically deformed when the external impact is applied at the same time to save the resin material during molding to increase the cushioning properties.

At this time, the main body 20 is provided with a U-shaped groove 27 in the entire length of the bent portion, the U-shaped groove 27 is reinforced with a plurality of circular ribs (27a). As shown in Figure 3, the three-sided member of the main body 20 is connected through the U-shaped groove 27, so it is easy to fold and unfold as indicated by the double-dot chain line. The circular ribs 27a are formed to maintain a constant interval and width in the direction in which the thickness of the U-shaped grooves 27 is increased. Even if the main body 20 is repeatedly folded and unfolded, fatigue destruction of the U-shaped grooves 27 is prevented by the circular ribs 27a. In the case of using a paper material such as corrugated cardboard or pulp mold, it is difficult to form a U-shape and thus becomes a V-shape. On the other hand, the folding operation is relatively easy, but is easily cut when repeated use.

The cover 30 according to the present invention is provided with locking projections 33 and 34 having a cross section so as to be coupled to the locking grooves 23 and 24 of the main body 20, respectively, by the ribs 36 of the upper surface. Absorb the shock. The locking jaws 33 and 34 extend in the horizontal plane of the cover 30 and are bent downward at the ends. The locking jaw 33 of one side protrudes from the center to be engaged with the locking groove 23 of one side, and the locking jaw 34 of the other protrudes from both sides to be engaged with the locking groove 24 of the other side. The inner surface bent downward in the locking step (33) (34) maintains the dimensions to contact the outer surface of the locking groove (23) (24). The partition 31 which supports the panel product P is formed in the bottom surface of the cover 30, and the rib 36 is formed in the upper surface.

At this time, the ribs 25 and 26 of the main body 20 and the ribs 36 of the cover 30 are formed in an uneven shape so that the thickness thereof varies. The uneven structure of the ribs 25, 26 and 36 improves the cushioning function against external shock while saving the resin material. Reference numeral 25 is a concave form at the center, and 26 and 36 are convex forms at the center.

In addition, the partition walls 21, 22, 31 and the ribs 25, 26, 36 are preferably formed in a cross section that is closer to a trapezoid than an angular rectangle. Rounding the corners reduces wear and improves durability by absorbing shocks.

In the present invention, since the locking grooves 23 and 24 and the locking projections 33 and 34 propose asymmetrical structures from side to side, there is a direction in coupling the cover 30 to the body 20. This is only to keep the packaging of the panel product (P) in a uniform direction, so it is not limited to this may alternatively change to a symmetrical structure from side to side.

Meanwhile, although not shown in the drawing, a feeder for injecting the pre-molding material of the main body 20 and the cover 30 and a compact piece for ejecting the product after molding are formed on the outer surfaces of the ribs 25, 26, 36. It is good to put.

In use, the three sides of the main body 20 are folded into a box (not shown) as shown in FIG. 3, and then the panel products P are inserted into the partition walls 21 and 22 one by one, and finally the cover 30 as shown in FIG. 4. ) And the locking step (33) (34) is engaged with the locking grooves (23) (24) of the main body 20, the cover is covered with a plastic wrap and bundled with a band to complete the packaging. If the size of the panel product (P) is small and transported in a short distance, it is possible to omit the above box and tie the band directly to the outer surface of the main body 20 and the cover 30. The use of the uneven structure of the ribs 25, 26 and 36 when binding the band prevents slippage of the band.

At this time, when the main body 20 and the cover 30 is molded in a suitable amount of pigments such as black, blue, red, yellow, various colors are expressed. This makes it easy to classify products by type, use, and transport area on site. A pigment is used in the range which does not weaken the physical property of foamed resin material.

According to the above configuration and operation, the present invention can be used semi-permanently repeated while protecting the plate-shaped finished products or intermediate products such as TFT-LCD safe from external shock, thereby reducing the logistics cost.
