Description
BACKGROUND OF THE INVENTION

1. Field of the Invention


The present invention relates to an improved structure for fragile plate packaging and protection device, and in particular to a packaging box capable of accommodating fragile plates of various sizes, and having better carrying and protection capability, so as to prevent damages of fragile plates in a positive manner.


2. The Prior Arts


In general, the transportation of an ordinary fragile plate, such as a glass substrate, a liquid crystal panel, a solar energy module plate, or a plasma display panel glass substrate is realized through a box main body having a very good shock-proof and buffering capability to provide sufficient protection, so as to reduce the possibility that the fragile plate may be damaged or even be broken during its transportation.


Referring to FIG. 1 for a packaging box structure of a kind of fragile plate according to the prior art. As shown in FIG. 1, such a packaging box structure includes: a box main body 10, and a box cover 11, the box main body 10 and the box cover 11 are made of a plastic foaming material. Wherein, a protection plate 12 is provided each correspondingly on both sides of the box main body 10, and a plurality of insertion slots 13 are provided on the protection plate 12. Each of the insertion slots 13 is used to embed a fragile plate, thus providing the positioning and protection functions for a fragile plate during transportation. However, for a conventional packaging box structure of fragile plates as shown in FIG. 1, since a protection plate 12 is formed directly on a box main body 10, thus it will be very uneconomical that, the entire box main body must be replaced when insertion slots 13 are damaged or are unable to effectively hold the fragile plates. Meanwhile, since this kind of design is not fit for transporting fragile plates of various different sizes, therefore, transportation boxes of various sizes must be prepared, hereby resulting in an increase of cost of transportation.


Therefore, another kind of transportation box is proposed that its protection plate can be installed separately and it fits for various sizes of fragile plates. Referring to FIG. 2 for a transportation box of a glass substrate as disclosed in Patent Publication Number 456363 of Taiwan, ROC. As shown in FIG. 2, a glass substrate transportation box 20 includes a box main body 21, a removable slot insertion plate 22, and a removable slot insertion plate stand 23. The removable slot insertion plate 22 and the removable slot insertion plate stand 23 are each provided with a plurality of fixing slots 25. As such, through the plurality of insertion slots 25 disposed on the removable slot insertion plate 22 and the removable slot insertion plate stand 23 for securing the fragile plates, and by utilizing insertion slots 24 that are used to receive the inserted removable slot insertion plates at various portions of a box main body, though this kind of arrangement may improve the shortcomings of the prior art as shown in FIG. 1 that protection plates 12 are formed directly on a box main body 10, so that the entire box main body has to be replaced, when the insertion slots 13 are damaged or are not able to hold glass substrates effectively. Moreover, this kind of design and arrangement are suitable for transporting fragile plates of various sizes.


However, regardless of the design that the protection plate 12 as shown in FIG. 1 or the removable slot insertion plate 22 as shown in FIG. 2 is an integrally formed or a separable protection plate structure, yet in both the cases, the insertion slots are mainly used to hold and fix fragile plates effectively, thus when the gaps between insertion slots are getting overly large, then the insertion slots are not able to hold and fix the fragile plates stably, and thus is liable to cause vibrations during the process of fragile plate transportation, in addition, there exists no buffer protection structure in contact with fragile plates, thus increasing the possibility of its being damaged. In particular, the four corners of a fragile plate are most vulnerable to the vibrations, and therefore are liable to be damaged first.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The purpose, construction, features, functions and advantages of the present invention can be appreciated and understood more thoroughly through the following detailed description with reference to the attached drawings.


Referring to FIGS. 3, 4, and 5 for a perspective, an exploded perspective, and an exploded perspective views respectively of an improved structure for a packaging and protection device of fragile plates according to an embodiment of the present invention. As shown in FIGS. 3, 4, and 5, a fragile plates packaging and protection device 30 includes: a box main body 31, a bottom plate 33, two first fixing elements 34, two second fixing elements 35, a plurality of buffer elements 36, and a plurality of positioning strips 37.


Wherein, the box main body 31 is provided with an accommodating space, and a box cover 32 used to cover and close an opening of the box main body. The bottom plate 33 is provided in the accommodating space of the box main body 31 and is in contact with a bottom portion of the box main body 31. Two first fixing elements 34 are provided in an accommodating space of the box main body 31 face-to-face, and are disposed vertically at the bottom portion of the box main body 31. In addition, two first fixing elements 34 are each provided with a plurality of first fixing slots 341, and each of the bottom portions of a plurality of first fixing slots 341 is provided respectively with embedded slots 38 of a right angle configuration (as shown in FIG. 6). In an embedded slot 38 is provided with a buffer element 36. A plurality of buffer elements 36 are each provided with a gap (as shown in FIG. 7) and are in a configuration of a right-angle triangle, so that corners of a bottom portion of a fragile plate 40 can slide downward along the first fixing slots 341 of two first fixing elements 34 to the gaps of buffer elements 36. Each of the two second fixing elements 35 is also provided with a plurality of second fixing slots 351, and a top portion of each of a plurality of second fixing slots 351 is also provided with an embedded slot 38 in a right angle configuration respectively (as shown in FIG. 6). In an embedded slot 38 is provided with a buffer element 36. When each of the two second fixing elements 35 is installed in an accommodating space of a box main body 31, through the sliding downward of the two sides of a fragile plate 40 along the second fixing slots 351, thus corners of a top portion of a fragile plate 40 are placed in the gaps of the buffer elements 36 of the second fixing slots 351.


Since a buffer element 36 is provided respectively in an embedded slot 38 of a first fixing slot 341 and a second fixing slot 351. Therefore, a bottom surface of a fragile plate 40 is in contact with a bottom plate 33, and both sides of a fragile plate 40 are in close contact with a first fixing slot 341 and a second fixing slot 351.


In addition, a fragile plate packaging and protection device 30 further includes a plurality of positioning strips 37, and each of the plurality of positioning strips 37 is provided with a plurality of positioning slots 371 respectively, such that the positioning strips 37 are placed on a top surface of a box cover 32 and are in contact with the box cover 32. When the box cover 32 is put and closed on a box main body 31, a top surface of a fragile plate 40 is in close contact with a positioning slot 371 of a positioning strip 37 respectively.


Since when a box cover 32 is put and closed on a box main body 31, a bottom surface of a fragile plate 40 is in contact with a bottom plate 33, thus the bottom plate is able to share the gravitation force of a fragile plate. Moreover, since each of the four corners of a fragile plate 40 is placed in a gap of a buffer element 36, so that the fragile plate can be placed stably in the first fixing slots 341 and the second fixing slots 342, hereby overcoming the problem that the gaps of fixing slots are too large to hold a fragile plate stably. Meanwhile, each of the two sides of a fragile plate 40 is in close contact with a first fixing slot 341 or a second fixing slot 342 respectively, thus an upper top surface of a fragile plate is in close contact with a positioning slot 371 of a positioning strip 37, such that when a packaging and protection device is subject to a piling, mounting & dismounting, or transportation process, the vibrations incurred can be reduced, thus the four corners of a fragile plate is protected from being damaged.


Furthermore, a bottom plate 33 of a fragile plate packaging and protection device 30 can also designed into having a plurality of positioning strips (not shown), thus when a fragile plate is positioned stably in a positioning slot of a positioning strip, the gravitation force can also be shared by the positioning slot. Meanwhile, in case that the bottom portion of a first fixing slot and the top portion of a second fixing slot are not provided with embedded slots, then the thickness of a bottom plate and a positioning strip can be increased correspondingly, so that the first positioning slot and the second positioning slot can be in a complete close contact with the top surface and the bottom surface of a fragile plate, hereby avoiding gaps that may lead to the damage of a fragile plate.


In addition, in the present embodiment, one of the major functions of a bottom plate 33, two first fixing elements 34, two second fixing elements 35, and a positioning strip 37 is to share the gravitation force, buffering and absorbing vibrations, thus the material utilized is preferred to be an Extruded Polyethylene (EPE) or an Extruded Polypropylene (EPP), however, the present invention is not limited to this. Meanwhile, in addition to the functions of buffering and absorbing vibrations, a buffer element 36 is used to hold a fragile plate 40 stably in a first fixing slot 341 and a second fixing slot 352, as such, it is preferably made of a plastic material, preferably Polypropylene (PP) material, however, the present invention is not limited to this.


Furthermore, referring to FIG. 8 for an improved structure of a fragile plate packaging and protection device according to another embodiment of the present invention. The assembly principle utilized in the present embodiment is the same as that of the previous embodiment, yet the difference is that the fragile plate packaging and protection device 30 can match and accommodate fragile plates 40 of various sizes. In case that a fragile plate 40 is of a smaller size, then the bottom plate 33 can be designed to be a smaller size, or at least a positioning strip 37 is utilized to match the length of a fragile plate 40, meanwhile, two first fixing elements 34 and two second fixing elements 35 are made to move closer to each other, so that the fragile plate 40 can be held stably in a first fixing slot 341 and a second fixing slot 351. However, when two first fixing elements 34 and two second fixing elements 35 are made to move closer to each other, a gap will be formed between a first fixing element 34, a second fixing element 35, and a box main body 31 respectively, as such, a fragile plate 40 is liable to displace and move during a transportation process and thus be damaged. Therefore, when the size of a fragile plate 40 is smaller such that a first fixing element 34 and a second fixing element 35 can not be in close contact with inner walls of a box main body 31, then a padding element 39 can be used to fill in and pad the gap. The padding element 39 is made of a foaming material, such as Extruded Polyethylene (EPE) or Extruded Polypropylene (EPP), however, the present invention is not limited to this. Therefore, in addition to being able to fix the elements inside a box main body 31, a padding element 39 is also capable of buffering and absorbing shocks and vibrations, thus enhancing the protection effect of a fragile plate packaging and protection device 30.


In addition, in case that the size of a fragile plate 40 is changed to a larger or smaller size in height, so that a fragile plate 40 is higher or lower, namely higher or lower than the original fragile plate, and since the first fixing element 34 and the second fixing element 35 are able to make vertical movements in an up-and-down direction, thus in case that a fragile plate 40 is higher or lower, then up-and-down movements of adjustment can be made through two second fixing elements 35. Naturally, in case that a fragile plate 40 is too high, such that a distance between a first fixing element 34 and a second fixing element 35 is too large, then a connection plate can be added additionally between the first fixing element 34 and the second fixing element 35, so that the fragile plate 40 can have better protection.


Summing up the above, through the application of the present invention, excellent safety, practicality, and economy can be achieved for a packaging and protection device of fragile plates. As such, it is indeed a superior results of creative thinking, thus it is prepared for a patent application. However, the above description is intended merely for presenting Preferred Embodiments of the present invention, and any variations or modifications of the present invention are within the scope of the appended Claims.


The above detailed description of the preferred embodiment is intended to describe more clearly the characteristics and spirit of the present invention. However, the preferred embodiments disclosed above are not intended to be any restrictions to the scope of the present invention. Conversely, its purpose is to include the various changes and equivalent arrangements which are within the scope of the appended claims.
