Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.
[0024] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0025] like Figures 1 to 5 As shown, this application provides an easy-to-store aluminum foil packaging bag, comprising:
[0026] An aluminum foil packaging bag 100 includes a front layer 10, a back layer 20, a separating mechanism 40, a heat-sealing section 50, and a bag opening 60. The separating mechanism 40 is disposed inside the front layer 10 and the back layer 20. The heat-sealing section 50 is a heat-sealed joint formed by heat-sealing the front layer 10 and the back layer 20 on three sides. The bag opening 60 is disposed on the unsealed portion remaining after the heat-sealing sections 50 on the front layer 10 and the back layer 20 on the three sides. A folding mechanism 30 is disposed on one side of the heat-sealing section 50 and includes multiple equally spaced circular holes 31 on one side of the heat-sealing section 50 and folding creases 39 equally spaced on the outer walls of the front layer 10 and the back layer 20. A fixing block 32 is heat-sealed to one side of the heat-sealing section 50. A pull rope 33 is disposed on one side of the fixing block 32. The pull rope 33 enters from the bottommost circular hole 31, passes through each circular hole 31 upwards, and finally exits from the topmost circular hole 31.
[0027] After adopting the above technical solution, by setting a folding mechanism 30 on one side of the hot melt section 50, when it is necessary to store the aluminum foil packaging bag, by pulling the end of the pull rope 33 away from the fixing block 32, the front layer 10 and the back layer 20 are folded along the storage crease 39 set on their outer wall during the pulling process, the aluminum foil packaging bag can be quickly folded and stored.
[0028] It should be noted that when it is necessary to store the aluminum foil packaging bag, simply pull the end of the pull cord 33 away from the fixing block 32. During the pulling process, the front layer 10 and the back layer 20 are folded along the storage crease 39 set on their outer walls. At this time, press the pressing block 36 on one side of the positioning block 34 to make the pressing table 38 on the outer wall of the pressing block 36 move down and stop pressing the pull cord 33. Move the positioning block 34 along the pull cord 33 to the storage crease 39 closest to it and release the pressing block 36. The rebound force of the spring 37 makes the pressing block 36 reset so that the pressing table 38 on its outer wall presses the pull cord again. 33 This fixes the position of the positioning block 34, preventing the aluminum foil bag from springing back after folding. When using the aluminum foil bag, the positioning block 34 is unlocked and pulled to the top of the pull rope 33. After the movement is complete, the aluminum foil bag is unfolded again, allowing for quick use. During the use of the aluminum foil bag, the aluminum foil divider 41 can be pulled up and the release paper on the outer wall of the double-sided adhesive 42 can be removed. The double-sided adhesive 42 after removing the release paper is then bonded to the inner wall of the attachment strip 43, thereby dividing the interior of the aluminum foil bag into multiple different storage areas, making it easier to classify the stored items.
[0029] In an optional embodiment, a boss 61 is integrally provided on the outer wall of the bag opening 60. By providing a boss 61 on the outer wall of the bag opening 60, the two bosses 61 can be quickly separated by rubbing the boss 61.
[0030] In an optional embodiment, a convex zipper 63 is heat-fused to the inner wall of the bag opening 60 located at the front layer 10, and a concave zipper 62 is heat-fused to the inner wall of the bag opening 60 located at the rear layer 20. The front layer 10 and the rear layer 20 are sealed by the concave zipper 62 in conjunction with the convex zipper 63.
[0031] In an optional embodiment, the separating mechanism 40 includes an aluminum foil separator 41 heat-fused to the inner wall of the back layer 20 and an attachment strip 43 bonded to the inner wall of the back layer 20. Double-sided adhesive 42 is bonded to one side of the outer wall of the aluminum foil separator 41. By pulling up the aluminum foil separator 41 and removing the release paper from the outer wall of the double-sided adhesive 42, the double-sided adhesive 42 after removing the release paper is bonded to the inner wall of the attachment strip 43, thereby dividing the interior of the aluminum foil packaging bag into multiple different storage areas, which facilitates the classification of the stored items.
[0032] In an optional embodiment, a positioning block 34 is provided at one end of the outer wall of the pull cord 33. A connecting groove 35 is provided on both the left and right sides of the positioning block 34. A pressing block 36 is slidably connected inside the positioning block 34. A pressing table 38 is fixedly installed on the outer wall of the pressing block 36. By pressing the pressing block 36 on one side of the positioning block 34, the pressing table 38 on the outer wall of the pressing block 36 moves down and no longer presses the pull cord 33, thereby unlocking the positioning block 34 from the outer wall of the pull cord 33. The folded aluminum foil packaging bag is shaped by moving the position of the positioning block 34 to prevent it from springing back after folding.
[0033] In an optional embodiment, a spring 37 is provided between the inner wall of the pressing block 36 and the positioning block 34. By providing the spring 37, the pressing block 36 can be automatically reset, and the spring 37's rebound force can cause the pressing table 38 to press into the outer wall of the pull rope 33, thereby fixing the position of the positioning block 34 on the pull rope 33.
