1. Field of the Invention
The present invention relates to a type of container usually used in large numbers, and more particularly to a stackable container for holding and transporting objects such as LCD panels.
2. Description of the Prior Art
When LCD displays are mass produced, the process usually includes a preliminary process for fabricating LCD panels, and then an assembly process for attaching backlight modules, driving circuits and frames to the LCD panels to thereby produce the LCD displays. The preliminary process and the assembly process are generally performed at different work areas of a factory. The fabricated LCD panels are commonly placed in containers, which are then transported to the assembly work area. The containers protect the LCD panels from damage, and help reduce production costs.
Taiwan patent publication No. 456363 issued on Sep. 21, 2001 discloses a container for holding fragile LCD panels. Referring to
The body 1 includes a pair of opposite sidewalls, and a partition wall 11 midway between the sidewalls. At least two pairs of mutually opposite arrays of insertion slots 12 are defined in the sidewalls and the partition wall 11. First recesses 13 are defined in a bottom of the body 1. Second recesses 21 are defined in a top of the cover 2. The slotted plates 3, 4 respectively define a plurality of slots 31, 41 in one side thereof. The slotted beams 3 further include a backboard 32 that can be inserted into corresponding inserted slots 12 of the body 1. The slotted bottom beams 4 are mounted in the recesses 13, 21 of the body 1 and the cover 2, with fastening protrusions 42 of the slotted bottom beams 4 engaging in fastening sockets 44 located at the first recesses 13 and the second recesses 21. LCD panels are then inserted into the slots 31 of the slotted beams 3, and the cover 2 is mounted onto the body 1. Thus top and bottom ends of the LCD panels are held in the slots 41 of the slotted bottom beams 4 that are located in the bottom of the body 1 and the top of the cover 2 respectively.
Because the slotted beams 3 and the slotted bottom beams 4 are made of an expanded plastic having a high coefficient of expansion, they provide adequate shock-proofing so as to protect the LCD panels from damage during loading, transportation and unloading. In addition, the body 1 and the cover 2 are made of an expanded plastic having a low coefficient of expansion, so that they can withstand external impact and protect the LCD panels from damage.
After the LCD panels are unloaded from the containers, the empty containers must be taken back to the loading area where LCD panels are fabricated. The empty containers occupy a large space, which makes their transportation unduly efficient, and this in effect increases costs.
SUMMARY OF THE INVENTIONIt is therefore an objective of the present invention to provide a stackable container that can increase the efficiency of its mass transportation and thereby reduce costs.
In order to achieve the above objective, a stackable container for storing panels includes a box including a plurality of sidewalls and a bottom, the sidewalls and bottom cooperatively defining a receiving space having an opening; and a holding means removably engaged in the box, for receiving and holding the panels in the box; wherein an area of the opening is larger than an area of the bottom.
When the stackable container is not in use, the holding means can be removed, so that the box is empty. A plurality of the boxes can then easily be stacked. In addition, a plurality of the holding means can be easily stored together. Consequently, the stackable container saves a great deal of space during storage and transportation thereof. Thus, the costs of storage and transportation of the stackable container are reduced.
Other objects, advantages, and novel features of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings, in which:
BRIEF DESCRIPTION OF THE DRAWINGS

Referring to
The holding means 61 includes two first slotted beams 70, two second slotted beams 80, and a slotted bottom beam 90. The first slotted beam 70, the second slotted beams 80, and the slotted bottom beam 90 are all made of an expanded plastic having a high coefficient of expansion, such as expanded polypropylene (EPP). Each first slotted beam 70 defines a plurality of parallel first slots 72. A first fastening protrusion 71 is formed on each of opposite ends of the first slotted beam 70. Each second slotted beam 80 has an “L” shaped profile. The second slotted beam 80 defines a plurality of parallel “L” shaped second slots 82. A second fastening protrusion is formed on each of opposite ends of the second slotted beam 80. The slotted bottom beam 90 defines a plurality of parallel third slots 92. A third fastening protrusion 91 is formed on each of opposite ends of the slotted bottom beam 90.

The cover 50 defines a channel 51 in a periphery of an underside thereof. The channel 51 fasteningly receives the flange 65 of the box 60, so that the cover 50 is tightly attached onto the box 60. Consequently, the cover 50 and the box 60 cooperatively define a sealed space therein. Preferably, a gasket (not shown) is disposed in the channel 51, to increase the hermetic sealing of the cover 50.
In assembly of the stackable container 100, the second slotted beams 80 are mounted into the recesses 67 of the box 60, with the second fastening protrusions 81 removably engaging in the second fastening sockets 643. The slotted bottom beam 90 is mounted in the recess 68, with the third fastening protrusions 91 removably engaging in the third fastening sockets. The first slotted beams 70 are mounted in an upper portion of the box 60, with the first fastening protrusions 71 removably engaging in the first fastening sockets 641. After such mounting, the first slots 72, the second slots 82, and the third slots 92 are aligned with each other in one-to-one correspondence, for cooperatively receiving and holding LCD panels.
Referring also to
In addition, the cover 50 is substantially a flat board, so that a plurality of the covers 50 can easily be stacked. Furthermore, a plurality of the slotted beams 70, 80 and the slotted bottom beams 90 can be easily stored together. Consequently, the stackable container 100 saves a great deal of space during storage and transportation thereof. Thus, the costs of storage and transportation of the stackable container 100 are reduced.
It is to be understood that even though numerous characteristics and advantages of the present invention have been set out in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
