The invention will now be further described with reference to the accompanying drawings.

1 to 4 each show a liquid crystal panel package 10 (referred to as a package 10) according to the present invention. The package 10 includes a case 2. As shown in FIG. 5, the casing 2 has a bottom wall 21 and a peripheral wall 22, and an open cavity 23 defined by the bottom wall 21 and the peripheral wall 22. The opening of the open mouth 23 is located at the top end of the case 2 so that the operator places the liquid crystal panel 1 into the open cavity 23.

In one embodiment, a first superposed structure 24 is provided on the top end of the casing 2, and a second superposed structure is provided on the bottom end of the casing 2. After the first superposed structure 24 of one liquid crystal panel package 10 and the second superposed structure of the other liquid crystal panel package 10 are superposed on each other, the two packages 10 can be prevented from slipping each other. The first and second superimposed structures are well known to those skilled in the art and will not be described in detail herein.

As shown in FIG. 2, the liquid crystal panel package 10 further includes a multilayer spacer 3 disposed in the open cavity 23. The multilayer gasket 3 may be made of a highly elastic material such as foam or pearl cotton. The multilayer spacer 3 is used to sandwich the liquid crystal panel 1 one by one to ensure that the liquid crystal panel 1 is not damaged during transportation. Among them, the so-called one-by-one clamping means that the liquid crystal panels 1 are respectively arranged between the two spacers 3. Since the open cavity 23 is for accommodating the liquid crystal panel 1, and the liquid crystal panel 1 is normally rectangular again, the open cavity 23 of the present embodiment is also rectangular, but means that other shapes are not possible. In this embodiment, the peripheral wall 22 is a rectangular peripheral wall (see Fig. 5) composed of four side walls 22a for forming a rectangular open cavity 23, whereby the use of raw materials can be saved, and the compact structure can be promoted.

According to the present invention, a card slot is provided inside the peripheral wall 22 of the casing 2 (see Figs. 1-5), and a tab is provided on the outer edge of the gasket 3 (see Fig. 6). The tab can cooperate with the card slot and prevent each pad 3 from being turned upside down The sliding of the crucible is parallel to the bottom wall 21, thereby preventing the edge of the gasket 3 from being curled, preventing the flip chip of the liquid crystal panel 1 from being squeezed, and ensuring the safety of the liquid crystal panel 1 and its flip chip.

In the embodiment shown in FIG. 5, the card slot includes a first opening 501 that is substantially parallel to the top surface of the case 2, and a second opening 502 that faces the open cavity 23. The opening size of the second opening 502 is smaller than the maximum inner dimension L _{Max of the} card slot. The shape of the card slot may be a polygon such as a rectangle, a trapezoid, or a diamond when viewed in a direction perpendicular to the first opening 501. The maximum internal dimension L _Max of the card slot may be the diagonal length of the rectangular card slot or the base length of the trapezoidal card slot. Since the shape of the card slot and the tab are the same, and the maximum inner dimension L _{Max of the} card slot is smaller than the opening size of the second opening 502, the tab inserted into the card slot from the first opening 501 will not be able to escape from the second opening 502. This makes it possible to prevent the gasket 3 from slipping correspondingly to avoid curling of its edges.

In one embodiment, the card slot includes a plurality of trapezoidal slots 51 (see FIG. 5) disposed on each of the side walls 22a, the tabs including a trapezoidal tab 61 disposed on the outer edge of the spacer 3 (see FIG. 6). . When the trapezoidal tabs 61 are respectively embedded in the corresponding trapezoidal grooves 51 from the first opening 501, the spacers 3 will not be able to slide parallel to the bottom wall 21, whereby curling of the edges of the spacers 3 can be avoided. However, since each of the side walls 22a can pull the outer edge of the spacer 3 through the mating structure of the trapezoidal groove 51 and the trapezoidal tab 61, the spacer 3 has to be flat and stable, so that the fixing of the liquid crystal panel 1 is more stable.

The crystal panel package 10 according to the present invention may further include a first pressing member 7 provided in each of the trapezoidal grooves 51. The first pressing member 7 serves to prevent the liquid crystal panel 1 from being relatively slid between the corresponding spacers 3 in order to secure the transportation of the liquid crystal panel 1.

In a preferred embodiment, the first pressing member 7 comprises a rectangular block 71 and a trapezoidal block 72 fixed at an angle of 90 to it, which is clearly shown in FIG. The rectangular block 71 and the trapezoidal block 72 may be integrally formed. As shown in FIG. 4, the first pressing member 7 can embed its rectangular block 71 into the trapezoidal groove 51 from the groove wall away from the second opening 502, and the bottom surface of the trapezoidal block 72 and the uppermost spacer 3 contact. When an object such as another liquid crystal panel package 10 is overlaid on the top end of the case 2, the bottom of the liquid crystal panel package 10 can apply pressure to each of the spacers 3 through the trapezoidal block 72 to increase the spacer 3 and the liquid crystal panel. The friction between 1 prevents the liquid crystal panels 1 from sliding between the corresponding spacers 3, thereby ensuring the safety of the liquid crystal panel 1 and its flip chip.

In order to prevent the first pressing member 7 from being inclined, a first positioning groove 8 (see Fig. 2) for accommodating and positioning the rectangular block 71 is provided on the groove bottom of the trapezoidal groove 51. Preferably, the bottom shape of the rectangular block 71 is the same as the shape of the first positioning groove 8, and the size is also the same. When the rectangular block 71 is inserted into the first positioning groove 8, the inclination of the first pressing member 7 can be avoided. The stability of the first pressing member 7 is enhanced.

As shown in FIGS. 1 and 3, the card slot may further include an open rectangular groove 52 provided at a corner of the rectangular peripheral wall 22. The opening angle of the open rectangular slot 52 is the second opening 502. At the same time, the tab further includes a notched rectangular tongue 62 (see Fig. 6) provided at the corner of the spacer 3. The notch of the notched rectangular tongue 62 corresponds to the open angle of the open rectangular slot 52. When the notched rectangular tongues 62 are respectively embedded in the corresponding open rectangular grooves 52 from the first opening 501, the sliding of the spacers 3 parallel to the bottom wall 21 can be prevented, thereby preventing the edges of the spacers 3 from being rolled up. side. On the basis of the cooperation of the trapezoidal groove 51 and the trapezoidal tongue 61, the cooperation of the open rectangular groove 52 and the notched rectangular tongue 62 is further increased, and the structure of the gasket 3 is further promoted.

The liquid crystal panel package 10 according to the present invention may further include a second pressing member 9 (see Fig. 3) provided in each of the open rectangular grooves 52, respectively. The second pressing member 9 serves to prevent the liquid crystal panel 1 from slipping between the corresponding spacers 3 in order to secure the liquid crystal panel 1 and its flip chip.

In the embodiment shown in Fig. 8, the second pressing member 9 includes a right-angled block 91 and a flat block 92 covering and fixed to the top end of the right-angled block 91. The right angle block 91 can be optionally integrally formed with the flat block 92. The second pressing member 9 can embed its right-angled block 91 into the open-angle rectangular groove 52 from the groove wall away from the second opening 502, and bring the bottom surface of the flat block 92 into contact with the uppermost spacer 3. When an object such as another liquid crystal panel package 10 covers the top end of the case 2, the bottom of the liquid crystal panel package 10 can apply pressure to each of the spacers 3 through the flat block 92 to increase the spacer 3 and the liquid crystal panel. The friction between 1 prevents the liquid crystal panel 1 from slipping between the corresponding spacers 3, thereby ensuring the safety of the liquid crystal panel 1 and its flip chip.

In order to prevent the second pressing member 9 from being inclined, a second positioning groove (not shown) capable of accommodating and positioning the right-angled block 91 is provided on the groove bottom of the open-angle rectangular groove 52. Since the second positioning groove has the same shape and the same size as the bottom end of the right-angled block 91, the right-angled block 91 can be stably positioned by the second positioning groove after being embedded in the second positioning groove to prevent the second pressure. The part 9 is tilted.

The liquid crystal panel packaging box 10 according to the present invention can prevent the gasket 3 in the packaging box 10 from slipping during the bumpy conveyance by the cooperation of the card slot and the tab, thereby preventing the edge of the gasket 3 from being curled, thereby The transportation of the liquid crystal panel 1 and its flip chip is ensured.
