Description

Technical Field

[0001] This utility model relates to the technical field of storage bags, and more specifically to a storage bag with a large opening. Background Technology

[0002] There is a type of large-capacity storage bag on the market that opens horizontally. The bag uses a zipper on the side, and when the zipper is open, the front and back sides of the bag can be laid flat 180° like a tray, creating a large, open design for easy access to items. However, the left and right ends of these bags, where the zipper ends are located, are made of soft fabric and not connected to the zipper. When the side zipper is closed, the left and right ends of the bag are not sealed and are easily deformed, causing items to easily fall out from either end. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a storage bag with a large opening, which uses a zipper to open and close on the side, and no zipper is connected to the left and right ends. While ensuring that the front and back sides of the storage bag can be laid flat like a tray at 180° when the zipper is opened, the zipper can prevent the items inside the storage bag from falling out from the left and right ends of the storage bag when it is closed.

[0004] The technical solution of this utility model is to provide a large-opening storage bag, including a bag body composed of a front side, a rear side, and two left and right end faces. The side of the bag body is provided with a zipper. The front side and the rear side are located on both sides of the zipper. The two left and right end faces are not connected to the zipper and are adjacent to the beginning and end of the zipper respectively. When the zipper is opened, the front side and the rear side can be laid flat 180° into a tray shape. The end face includes a rigid protective sheet and a first flap. The outer periphery of one of the protective sheet and the first flap is connected to the front side, and the outer periphery of the other is connected to the rear side. A soft second flap is provided between the protective sheet and the first flap. The second flap is connected to both the protective sheet and the first flap. The connection part between the second flap and the protective sheet is set as a first fold, which allows the second flap to be folded inward to the protective sheet. The connection part between the second flap and the first flap is set as a second fold, which allows the second flap to be folded outward to the first flap.

[0005] Compared with the prior art, the large-opening storage bag of this utility model has the following advantages: After the zipper is opened, the front and back sides of the storage bag can be laid flat at 180° to form a tray, realizing a double-opening design for easy access to the items inside the storage bag; as the zipper is gradually pulled up, the soft second flap folds outward from the second fold seam towards the outside of the first flap, and folds inward from the first fold seam towards the inside of the protective panel. When the zipper is fully pulled up, on the one hand, the second flap, together with the first flap, is located inside the protective panel, which can close the protective panel and prevent the items inside the storage bag from falling out from the side of the protective panel that is not connected to the front or back sides; on the other hand, the rigid protective panel will not deform and can play a protective role on the outermost side of the end face, preventing the items inside the storage bag from falling out from the two end faces.

[0006] Preferably, the rigid protective sheet comprises a rigid plate and a soft fabric wrapped around the outside of the rigid plate. Both the first and second flaps are made of soft fabric. The first fold seam is a stitch between the second flap and the soft fabric of the protective sheet, and the second fold seam is a stitch between the second flap and the soft fabric of the first flap. This structure facilitates the installation of the first and second fold seams.

[0007] Preferably, the second fold is angled, with the second fold located diagonally above and below the first fold. This structure facilitates the second folding outwards from the first fold as the zipper is gradually pulled up.

[0008] Preferably, the first flap is a right-angled triangle, with both right-angled sides connecting to the front or rear side, and the second fold is located on the hypotenuse of the first flap. This structure facilitates sewing the first and second flaps together; when the zipper is fully zipped up, the left and right ends can form a square shape.

[0009] Preferably, the second fold is vertical, and the second fold is located to the left or right of the first fold. This structure facilitates the second fold to fold outwards from the first fold as the zipper is gradually pulled up.

[0010] Preferably, the first flap is rectangular, with one adjacent side and the bottom edge of the first flap connected to the front or rear side. The second fold is located on the other side of the first flap. This structure facilitates sewing the first and second flaps together, and when the zipper is fully closed, the left and right ends can be square.

[0011] Preferably, the first fold is vertical, and the second fold is located on the left or right side of the protective panel. This structure allows the second fold to easily fold inwards towards the inside of the protective panel as the zipper is gradually pulled up.

[0012] Preferably, the first fold is located on the side or inner side of the protective sheet. This structure facilitates the sewing connection between the protective sheet and the second flap, and also facilitates the folding of the second flap inwards towards the protective sheet.

[0013] Preferably, the first fold is located on the side of the protective sheet, and both the protective sheet and the second flap have a rounded edge above the first fold that connects and transitions with it. This structure allows the second flap to close more snugly with the protective sheet, preventing interference between the second flap and the protective sheet above the first fold during the inward folding process, which would otherwise increase the gap between the second flap, the first flap, and the protective sheet.

[0014] Preferably, both the protective panel and the first flap are provided with connecting arc edges with a central angle of 10 degrees, which are used to connect with the front or rear side. This structure also allows the front and rear sides of the storage bag to be laid flat 180° like a tray when the zipper is opened, achieving a large double-opening design; when the zipper is fully closed, the left and right ends can be circular or semi-circular.

[0021] Example 1: like Figure 1 and Figure 2 As shown, the large-opening storage bag of this utility model includes a bag body 1 composed of a front side 3, a rear side 4, and two left and right end faces 5. A zipper 2 is provided on the side of the bag body 1. The front side 3 and the rear side 4 are located on both sides of the zipper 2. The two left and right end faces 5 are not connected to the zipper 2 and are adjacent to the beginning and end of the zipper 2 respectively. After the zipper is opened, the front side 3 and the rear side 4 can be laid flat 180° into a tray shape.

[0022] End face 5 includes a rigid protective sheet 5-1 and a first hinge 5-2. A portion of the outer periphery of the protective sheet 5-1 is at a right angle and connected to the front side 3. The first hinge 5-2 is a right-angled triangle, with both right-angled sides connected to the rear side 4. A soft second hinge 5-3 is provided between the protective sheet 5-1 and the first hinge 5-2. The second hinge 5-3 is connected to both the protective sheet 5-1 and the first hinge 5-2. The connection between the second hinge 5-3 and the protective sheet 5-1 is a first fold 5-4, which allows the second hinge 5-3 to fold inwards towards the protective sheet 5-1 as the zipper is gradually pulled up. The connection between the second hinge 5-3 and the first hinge 5-2 is a second fold 5-5, which allows the second hinge 5-3 to fold outwards towards the first hinge 5-2 as the zipper is gradually pulled up. When the zipper is fully zipped up, the two end faces 5 on the left and right can be square. The second fold 5-5 is located on the diagonal side of the first fold 5-2, that is, the second fold 5-5 is set diagonally, and the second fold 5-3 is located diagonally above the first fold 5-2; the two sides of the protective plate 5-1 are parallel and both are set vertically, and the first fold 5-4 is set on one side of the protective plate 5-1.
