Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging box for storing a plurality of CRT panels. 2. Description of the Related Art Conventionally, when a plurality of CRT panels are stored upright in a packaging box, a plurality of CRT panels are placed in an outer box (made of cardboard) in order to prevent minute scratches on the effective surface of the panel.
Although a plurality of resin partition members are accommodated and both ends of each panel are held by the partition members, the center of the outer box tends to open, and there is a disadvantage that the center panel cannot be sufficiently held. Therefore, as shown in FIGS. 4A and 4B, a partition member (1) made of corrugated cardboard is provided at the center of the outer box (11).
2). (13) is a partition member made of resin, and is stored facing both sides of the outer box (11). (14) are pads on the bottom and end faces, which are stored on both sides of the outer box (11). [0004] In the above-mentioned conventional device, a slit-like groove (12) intersecting with the partition member (12) is provided at the center of a resin partition member (13) holding the panel (15). 16) is required, and when used as a returnable box, a slit-shaped groove (1) at the center of the resin partition member (13) is required.
There was much more damage than in section 6). SUMMARY OF THE INVENTION It is an object of the present invention to prevent the central part of an outer box from being opened and to sufficiently hold the central panel without bringing any object into contact with a portion (effective surface) of the panel surface to be protected. Another object of the present invention is to provide a packaging box for a cathode ray tube which can be used for a long time as a returnable box by significantly reducing breakage of the partition member. [0006] In order to achieve the above object, the present invention comprises a rectangular box-shaped outer box and three surfaces that can be bent in a U-shape. It has a shape in which a plurality of convex portions that abut against the peripheral portion of the panel and support the panel in an upright state on two opposing surfaces are arranged side by side at intervals substantially equal to the width of the peripheral portion of the panel. In the state in which the two partition members are bent into a U-shape in an outer box and their respective central surfaces are back-to-back, and the back-to-back portion partitions the central portion of the outer box. It is stored. The two partition members according to the present invention do not have a slit-like groove as in the prior art, and therefore are less likely to be damaged. In addition, the two partition members were bent in a U-shape in the outer box, and the respective central surfaces were back-to-back, and the back-to-back portion was stored in a state of partitioning the center of the outer box. Opening can be prevented. Then, a plurality of panels are bent in a U-shape on two opposing surfaces of a partition member by a plurality of protrusions juxtaposed at intervals substantially equal to the width of the peripheral portion of the panel, and the panel surface is leaned up. It can be stored and held in the outer box without bringing any object into contact with the site (effective surface) to be protected. FIG. 1 is an exploded perspective view of a packaging box for a cathode ray tube according to the present invention, FIG. 2A is a front view of a developed state of a resin partitioning material according to the present invention, and FIG. FIG. 3C is a cross-sectional view taken along the line BB, FIG. 3C is a cross-sectional view taken along the line CC, and FIG. In FIG. 1, (1) shows a rectangular box-shaped outer box made of corrugated cardboard, (2) a partition member made of a resin vacuum molded product, and (3) shows bottom and end pads made of corrugated cardboard. I have. The bottom and end pads (3) have a bottom pad portion (3a) substantially identical to the bottom surface of the outer box (1), and an end face pad portion (3b) at both ends of the bottom pad portion (3a). It is formed and stored in the outer box (1). As shown in FIGS. 2 and 3, the partition member (2) has three surfaces (2a) (2) which can be bent in a U-shape.
b) (2c), and when bent into a U-shape, the peripheral portion (4) of the panel (4) is provided on two opposing surfaces (2a) and (2c).
a) a plurality of projections (2d) that abut against the panel (4) to support the panel (4) in a leaning state at intervals substantially equal to the width of the peripheral edge (4a) of the panel (4) (the drawing illustrates a case of three). Two partitioning members (2) are prepared and folded in a U-shape in the outer box (1), and the respective central surfaces (2b) and (2b) are back-to-back. Then, the back-to-back portion is stored in a state of partitioning the central portion of the outer box (1). The three surfaces (2a) (2) of the partition member (2)
b) (2c), reinforcing ribs (2e) are formed at appropriate intervals, and when folded into a U-shape, a panel (4) is provided below the two opposing surfaces (2a) and (2c). ), A ridge (2f) for holding a lower corner of the peripheral edge (4a) is formed in series with the protrusion (2d). The above three surfaces (2
a) A thin portion (2g) for bending into a U-shape is formed at the boundary between (2b) and (2c), and an auxiliary surface (2h) has a thin portion (2h) for bending at both ends. 2g). The present invention is constituted as described above. Next, a method for packaging the panel (4) will be described. First, the outer box (1)
The pad (3) is stored in the inside, and then the two partition members (2) and (2) are bent in a U-shape to form a central surface (2).
b) (2b) is back-to-back, and the back-to-back portion is stored in a state of partitioning the center of the outer box (1). Then, the two opposing surfaces (2a) (2) of each partition member (2) (2)
c) The panel (4) is stored in a leaning state in a space partitioned by the respective convex portions (2d) and (2d). Each panel (4)
Are stored in the partition members (2) and (2) on both sides such that the front surface (4b) of the panel (4) faces each other at the center of the outer box (1). Finally, a cardboard lid is placed on the upper surface, bound with a tying strap or the like, and shipped. Although the above-described embodiment exemplifies a case where six panels are stored, the number of stored panels is not limited to this and can be increased or decreased as appropriate. According to the present invention, the breakage of the resin partition member can be significantly reduced, and the partition wall can be used for a long time as a returnable box. Since the outer box is stored in a state in which the center of the outer box is partitioned back to back, the center of the outer box can be prevented from opening. Then, a plurality of panels are bent in a U-shape, and a plurality of projections juxtaposed on two opposing surfaces of a partition member are provided in a leaning state in a portion (effective surface) of the panel surface to be protected (effective surface). Can be housed and held in the outer box without making the contact.
