Third Embodiment

FIG. 15 is a top view showing a third embodiment of the packaging device when expanded according to the present invention.

As shown in FIG. 15, the packaging device for liquid crystal panel of the instant embodiment comprises: a first main body 10, the first main body 10 comprising a bottom 101, and a first side wall 102 and a second side wall 103 connected to two opposite sides of the bottom 101, wherein the two ends of the first side wall 102 and the two ends of the second side wall 103 respectively form a first opening and a second opening of the first main body 10; two second main bodies 20, each of the two second main bodies 20 comprising a bottom 201, and a fourth side wall 202 and a fifth side wall 203 connected to two opposite sides of the bottom 201, wherein a first end 202a of the fourth side wall 202 and a first end 203a of the fifth side wall 203 are connected by a sixth side wall 204; a second end 202b of the fourth side wall 202 and a second end 203b of the fifth side wall 203 form an opening of the second main body 20; wherein the openings of the second main bodies 20 are slightly smaller than the openings of the first main body 10 and the openings of the second main bodies 20 face respectively towards the first opening and the second opening of the first main body 10; the two second main bodies 20 are able to move adjustably into the first main body 10; the bottom 101, the first side wall 102, and the second side wall 103 of the first main body 10 and the bottom 201, the fourth side wall 202, the fifth side wall 203 and the sixth side wall 204 of the two second main bodies 20 form a loading space for loading the liquid crystal panel.

The instant embodiment differs from the first embodiment in that the first main body of the packaging device of this embodiment is disposed with two opposite openings and the two second main bodies 20 can move adjustably through the two openings into the first main body 10.

In summary, the packaging device for the liquid crystal panel according to the present invention uses an assembly of two main bodies, and one of the two main bodies is able to move adjustably. During the manufacturing of the device, no large-sized injection molding equipment is required so as to reduce the manufacturing difficulty and the cost. Also, the packaging device can be expanded when in use for loading large-sized panels, and the size of the packaging device can be reduced when idled or recycled to enhance the efficiency.

It should be noted that in the present disclosure the terms, such as, first, second are only for distinguishing an entity or operation from another entity or operation, and does not imply any specific relation or order between the entities or operations. Also, the terms “comprises”, “include”, and other similar variations, do not exclude the inclusion of other non-listed elements. Without further restrictions, the expression “comprises a . . . ” does not exclude other identical elements from presence besides the listed elements.

Embodiments of the present invention have been described, but not intending to impose any unduly constraint to the appended claims. Any modification of equivalent structure or equivalent process made according to the disclosure and drawings of the present invention, or any application thereof, directly or indirectly, to other related fields of technique, is considered encompassed in the scope of protection defined by the claims of the present invention.
