Description

FIELD OF THE INVENTION

The present invention relates to a technical field of packaging, and more particularly to a packaging carton.

The existing processes for manufacturing a liquid crystal display device generally includes the following steps:

Primary Array process: in this process, the whole array substrate and color filter substrate are manufactured.

Intermediate Cell Process: in the process, the array substrate and the color filter substrate are married or assembled together, filling with liquid crystal, and then cutting into panels of pre-determined dimensions.

Post Module Process: in this process, those panels will be further incorporated with other vital components, such as the backlight module, the circuits, and frame so as to complete the manufacturing of the liquid crystal display device.

However, once the panels is prepared with pre-determined dimensions, the panels have to be properly packed into storage boxes so as to deliver to an assembling factory for final assembling of LCD module.

As shown in FIG. 1, in the packaging carton 10, the glass substrates 12 and the but pads 11 are alternatively stacked therein. In order to prevent any occurrence of dust or powder resulted from impact during transportation from one place to the other, and consequently and negatively affecting the air quality of clean-room. It is desirably to have the packaging carton made from a certain material, such as Polypropylene (also known as PP), which features a certain rigidity as well as sound impact-absorbing capability. However, the PP is quite expensive, and is not beneficial for cost reduction for the final product.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

Detailed description will be given with the accompanied drawings.

Referring to FIGS. 2 and 3 which are a perspective and exploded view of a packaging carton made in accordance with the present invention; and a perspective and exploded view of a packaging carton with the bottom assembled completely, respectively.

As shown in Figures, the packaging carton 20 includes a container 21 and a top lid 22. The container 21 includes a base 211, a bottom buffering, pad 211, and a corner buffering pad 213. The base 211 is defined with a receiving space 23 for receiving a workload therein. The base 211 can be implemented into a drawer configuration. Alternatively, the base 211 can be configured by assembling different parts made from engineering plastic. In general, the engineering plastic parts may have two. In the present embodiment, the base 211 is inherited with a first buffering property. In addition, the base 211 is located at outmost peripheral and which does not in contact with the workload. In this regard, the base 211 can be made from material with certain buffering property, such as the engineering plastic which is comparably inexpensive, for example, Acrylonitrile butadiene styrene (ABS) or polyethylene (PE). In addition, in order to reduce the material cost while increasing the buffering performance, the base 211 can be made from hollowed board.

The bottom buffering pad 212 is disposed on the bottom of the receiving space 23 of the base 211. The bottom buffering pad 212 is inherited with a second buffering property which can properly protect the corners of the workload which are not covered and protected by the corner buffering pad 212. The bottom buffering pad 212 can be dimensioned to have the same dimension of the bottom of the receiving space 23 of the base 211, such that the whole bottom of the receiving space 23 can be covered by the bottom buffering pad 212. In one of the embodiments, the bottom buffering pad 212 can he made from polypropylene (PP) film.

The corner buffering pad 213 is disposed on corners of the receiving space 23 of the base 211, and which is dimensioned to match with the shape of the corners of the workload. The corner buffering pad 213 is directly in contact with the workload. The corner buffering pad 213 has an L-shaped configuration, and is configured with an L-shaped base board 2131 and L-shaped sidewall 2132 which extends upward from the base board 2131. In this embodiment, the sidewall 2132 of the corner buffering pad 213 can be arranged with a retainer or hook in a surface facing the base 211, while the base 211 is arranged with a corresponding buckle to engage with the retainer. By this arrangement, the corner buffering pad 213 can he readily and securely attached to the base 211. Of course, and it should be noted that the engagement between the corner buffering pads 213 and the base 211 is not limited to what disclosed above. For example, the corner buffering pad 213 can be glued to the base 211 or attached thereto with double-sided tape. The corner buffering pad 213 is inherited with a third buffering property. When the packaging carton 20 is used to pack the workload, when the packaging carton 20 contains the workload, the workload is directly supported and protected by the corner buffering pads 213 such that during the transportation, the workload will not in contact with the base 211 and no damages will be experienced. In the current embodiment, the corner buffering pad 213 can be made from material with excellent buffering performance, such as the expanded polypropylene (EPP). There are totally four corner buffering pads 213, and each is arranged in a corresponding corner of the receiving space 23 of the base 211. When the workload is seated into the base 211, those four corner buffering pads 213 withhold the workload respectively. As a result, not only the workload is properly supported, the corners of the workload are also well protected.

It should be noted and specially explained that the third and second buffering properties are superior to the first buffering property. It is for sure that the material with better buffering property will also be expensive as well. In the present invention, the base 211 which does not directly in contact with the workload can be made from material with ordinary buffering property, while the bottom buffering pad 212 and the corner buffering pad 213 can be made from material with excellent buffering performance. Since the usage of the material in making both the bottom buffering pad 212 and the corner buffering pad 213 is comparably small, accordingly, this can readily reduce the overall cost of the packaging carton.

Referring to again FIGS. 2 and 3, the top lid 22 is arranged on top of the container 21 so as to enclose the container 20. In the present invention, the container 20 is used to contain the liquid crystal display panels. Of course, the container is not limited only thereto.

In the current embodiment, the packaging carton made in accordance with the present invention includes a container configured with base integrated with the bottom buffering pads and corner buffering pads. With this arrangement, the bottom buffering pad which has excellent buffering performance is arranged on the bottom of the receiving space of the base, and the corner buffering pads with excellent buffering performance is arranged on each of the corners of the receiving space. Both of the bottom and corner buffering pads are directly in contact with the workload. However, the base which is made from material with comparably poor buffering performance as compared to the bottom and corner buffering pad is arranged on the outmost of the bottom buffering pad and the corner buffering pad. By this arrangement, when the packaging carton is used to contain the workload, the corner buffering pads can directly withhold the workload, while the base is indirectly withholding the workload. In this regard, the base can be made from material of less expensive. Once the cost of the packaging carton is reduced, the cost of final product is reduced as well.
