[0004] To achieve the above-mentioned purpose, the utility model discloses a connected double-cavity packaging bag, including a bag body and a diaphragm, wherein the diaphragm is arranged in the bag body to form a first cavity and a second cavity in the bag body, and the lower part of the diaphragm has a through hole that allows the first cavity and the second cavity to communicate with each other, a sealing film is arranged on the inner bottom surface of the bag body, and the periphery of the sealing film is heat-sealed with the surface of the diaphragm so that the sealing film seals the through hole of the diaphragm, and a tearing portion is arranged on the bottom surface of the bag body, and the sealing film and the diaphragm are separated by pulling the bottom surface of the bag body through the tearing portion, so that the first cavity and the second cavity are communicated through the through hole of the diaphragm.

[0005] Furthermore, the bag body includes a first bag sheet, a second bag sheet, and a bag bottom sheet, the bag bottom sheet is connected to the bottom of the first bag sheet and the second bag sheet, and the periphery of the bag bottom sheet is heat-sealed to the first bag sheet and the second bag sheet, and the periphery of the diaphragm is heat-sealed to the periphery of the first bag sheet or the second bag sheet.

[0006] Furthermore, the periphery of the sealing film is heat-sealed to the bag bottom film.

[0007] Furthermore, the tearing portion includes a first bottom hole and a second bottom hole, and the first bottom hole and the second bottom hole are located below the sealing film and are arranged on the bag bottom film, so that a pull ring is formed on the surface of the bag bottom film between the first bottom hole and the second bottom hole, and the sealing film is pulled apart from the through hole of the diaphragm by the pull ring.

[0008] Furthermore, it also includes a nozzle head, and the nozzle head is heat-sealed between the diaphragm and the first bag sheet or the second bag sheet.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] In the utility model, a sealing film for sealing the through hole is heat-sealed between the bottom surface of the packaging bag and the diaphragm to prevent the beverages in the first cavity from mixing with the beverages in the second cavity, so that beverages with different flavors can be stored. A pull ring is designed on the bottom surface of the packaging bag, so that the sealing film can be torn off the diaphragm by using the pull ring, so that the first cavity is connected with the second cavity, so that beverages with different flavors can be drunk or two flavors of beverages can be mixed to form a new flavor.

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0017] Reference Figure 1 , Figure 2 As shown, a connected double-chamber packaging bag includes a bag body 1, a diaphragm 2, and a nozzle head 3. The diaphragm 2 is arranged in the bag body 1. In this embodiment, the bag body 1 includes a first bag sheet 11, a second bag sheet 12, and a bag bottom sheet 13. The two sides of the bag bottom sheet 13 are respectively connected to the bottom of the first bag sheet 11 and the second bag sheet 12, and the periphery of the bag bottom sheet 13 is heat-sealed to the first bag sheet 11 and the second bag sheet 12, and the diaphragm 2 is arranged between the first bag sheet 11 and the second bag sheet 12. The periphery of the diaphragm 2 is heat-sealed to the periphery of the first bag sheet 11 or the second bag sheet 12. In this embodiment, the diaphragm 2 is heat-sealed to the first bag sheet 11 to form a first cavity 5 and a second cavity 6 in the bag body 1, so that drinks of different flavors can be accommodated. The nozzle head 3 is heat-sealed between the diaphragm 2 and the first bag sheet 11 or the second bag sheet 12, thereby forming a packaging bag with a double cavity.

[0018] More preferably, the lower portion of the diaphragm 2 has a through hole 21 that allows the first cavity 5 and the second cavity 6 to communicate with each other. In order to prevent the liquids in the first cavity 5 and the second cavity 6 from mixing with each other, a sealing film 4 is provided on the inner bottom surface of the bag body 1 in this embodiment. Specifically, the periphery of the sealing film 4 is heat-sealed to the bag bottom film 13, and the periphery of the sealing film 4 is heat-sealed to the surface of the diaphragm 2, so that the sealing film 4 seals the through hole 21 of the diaphragm 2 to prevent the liquid in the first cavity 5 from mixing with the liquid in the second cavity 6 through the through hole 21.

[0019] Furthermore, a tearing portion 7 is provided on the bottom surface of the bag body 1, and the tearing portion 7 includes a first bottom hole 71 and a second bottom hole 72. The first bottom hole 71 and the second bottom hole 72 are located below the sealing film 4 and are provided on the bag bottom film 13, so that a pull ring 73 is formed on the surface of the bag bottom film 13 between the first bottom hole 71 and the second bottom hole 72. Since the periphery of the sealing film 4 is heat-sealed to the bag bottom film 13, liquid can be prevented from leaking out from the first bottom hole 71 and the second bottom hole 72 through the gap between the sealing film 4 and the bag bottom film 13. The sealing film 4 is torn from the diaphragm 2 by grasping the pull ring 73 on the bag bottom film 13 and pulling the pull ring 73, so as to separate the sealing film 4 from the through hole 21 of the diaphragm 2, so that the first cavity 5 is connected to the second cavity 6, so that drinks of different flavors can be drunk or two flavors of drinks can be mixed to form a new flavor.

[0020] Of course, the above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. Any modifications made according to the spirit of the main technical scheme of the utility model should be included in the protection scope of the utility model.
