Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.
[0015] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.
[0016] Example 1
[0017] See also Figure 1 and Figure 2 As shown, a plastic bag involved in this embodiment includes a front box board 1 and a rear box board 2, wherein a side panel 3 that can be folded forward and backward is connected to the rear box board 2 and the front box board 1, and a closed chamber 4 is formed between the side panel 3 and the front box board 1 and the rear box board 2, and a compression spring 5 is provided in the closed chamber 4, one end of which is connected to the front box board 1 and the other end of which is connected to the rear box board 2, and a buckle ear 6 is hinged on the edge of the front box board 1, and the inner end face of the buckle ear 6 has a protrusion (not shown) that blocks the back side of the edge of the rear box board 2.
[0018] Furthermore, a take-in / put-out opening is provided on the front box plate 1, a take-in / put-out cover plate 7 is provided inside the take-in / put-out opening, and a zipper 8 is provided between the outer edge of the take-in / put-out cover plate 7 and the inner edge of the take-in / put-out opening.
[0019] Furthermore, a shoulder strap 9 is provided on the rear box panel 2 .
[0020] Furthermore, the compression spring 5 is arranged at the edge of the closed chamber 4 .
[0021] Furthermore, the side panels 3 are arranged at the edges of the front box panel 1 and the rear box panel 2 .
[0022] Furthermore, the front box panel 1 and the rear box panel 2 are both made of PP material; and the side panels 3 are made of soft rubber material.
[0023] In this embodiment, under the elastic force of the compression spring 5, the front box board 1 is away from the rear box board 2, the bag is opened by the spring, and the closed chamber 4 can be used to store objects. If the bag needs to be folded, the bag can be squeezed forward and backward until the front box board 1 and the rear box board 2 are close to each other, the compression spring 5 is compressed, and then the buckle ear 6 is rotated so that the upper protrusion is rotated to the back side of the edge of the rear box board 2, so as to achieve the locking and limiting effect between the front box board 1 and the rear box board 2.
