[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0022] like Figures 1-4 As shown, a bag opening assembly strip has a U-shaped structure. The assembly strip includes a base part 15, and a cover strip 10 is connected to the outside of the base part 15 through an elastic connecting part 14. The elastic connecting part 14 is made of TPU. A first slot 11 is formed between the base part 15 and the cover strip 10. The first slot 11 is used to engage with the edge of the lower cover 6 or the upper cover 7. A second slot 12 is formed on the base part 15. The opening directions of the first slot 11 and the second slot 12 are opposite. The second slot 12 is used to accommodate the zipper 5.
[0023] During installation, first flip up the cover strip 10, engage the first slot 11 with the edge of the lower cover 6 or upper cover 7, then place the zipper 5 in the second slot 12. Next, sew the base part 15, the edge of the lower cover 6 or upper cover 7, and the zipper 5 together. Finally, flip the cover strip 10 downwards to conceal the stitching, improving aesthetics. It should be noted that the base part 15 is made of rigid plastic to reinforce the bag opening, and the elastic connecting part 14 is made of elastic TPU material, allowing the cover strip 10 to be flexibly flipped upwards or downwards to adapt to the installation process.
[0024] like Figure 3 , Figure 4 As shown, a third slot 13 is provided on the inner side of the base part 15. The third slot 13 is used to accommodate the wire ring 3 at the edge of the partition bag 4.
[0025] During installation, first insert the wire ring 3 at the edge of the divider bag 4 into the third slot 13, and then use the buckle 2 to snap the wire ring 3 into the third slot 13 to prevent the wire ring 3 from falling off, thereby fixing the divider bag 4.
