Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging products, and in particular to a double-layer seasoning packaging bag. Background Technology
[0002] Instant noodles are a common type of convenience food. Currently, instant noodles usually have seasoning added after preparation. The seasoning includes powder and oil, which are stored in two separate packets. When needed, the two packets are torn open and the powder and oil are poured into the instant noodles. Although this separate packaging method ensures that the ingredients are easy to preserve, the powder is prone to spillage when the packet is opened and poured out. Also, if there is any residue in the packet after use, it can easily leak into other parts of the room and cause pollution. Utility Model Content
[0003] To address the aforementioned problems, this invention proposes a double-layer seasoning packaging bag that mixes powder and liquid by squeezing different cavities. The mixing amount of liquid and powder can also be adjusted by squeezing different cavities, and no powder spillage occurs during extrusion and disposal.
[0004] The technical solution adopted by this utility model is as follows:
[0005] A double-layer seasoning packaging bag includes a composite film, which is joined together to form a bag body. The bag body is provided with a dividing seal, a longitudinal weak seal, a first transverse weak seal, and a second transverse weak seal. These dividing seals divide the space within the bag body into independent and unconnected liquid chambers, a first powder chamber, a second powder chamber, and a third powder chamber. The longitudinal weak seal is located between the first powder chamber and the liquid chamber; the first transverse weak seal is located between the first powder chamber and the second powder chamber; and the second transverse weak seal is located between the second powder chamber and the third powder chamber. The width of the longitudinal weak seal is 0.1 mm to 0.2 mm, and the widths of the first and second transverse weak seals are both 0.1 mm to 0.2 mm.
[0006] In this type of packaging bag, the liquid chamber is used to hold oil, while the first, second, and third powder chambers are used to hold powder. Since the width of the longitudinal weak seal is 0.1 mm to 0.2 mm, and the widths of the first and second transverse weak seals are also 0.1 mm to 0.2 mm, the heat seal strength of these sections is relatively weak. When the chambers are squeezed, the gas or liquid inside will break the heat seal, thus achieving connection. Therefore, squeezing the liquid chamber can cause the longitudinal weak seal to rupture, allowing the oil to mix with the powder in the first powder chamber. Squeezing the first powder chamber can cause the first transverse weak seal and the longitudinal weak seal to rupture, allowing the powder in the first and second powder chambers to mix with the oil in the liquid chamber. Squeezing the second powder chamber can cause the first and second transverse weak seals to rupture, thus ensuring complete mixing of the powder in the first, second, and third powder chambers. Therefore, in this type of packaging bag, the mixing of liquid and powder, as well as the amount of liquid and powder to be mixed, can be achieved by squeezing different cavities. After the mixing is completed, the corresponding cavity can be cut open to squeeze out the mixture. When the liquid and powder are mixed, the mixture is squeezed out again. This can avoid the powder from spilling out during the extrusion process. At the same time, the corresponding cavity can be squeezed according to the needs to achieve the required amount of powder. The unused powder remains in the sealed state to prevent the powder from spilling to other places when discarded.
[0007] In summary, this type of packaging bag can mix powder and liquid by squeezing different cavities, and the mixing amount of liquid and powder can also be adjusted by squeezing different cavities. No powder spillage will occur during extrusion and disposal.
[0008] Optionally, the first transverse weak sealing portion and the second transverse weak sealing portion are in a parallel state, and the longitudinal weak sealing portion is in a state perpendicular to the first transverse weak sealing portion and the second transverse weak sealing portion.
[0009] Optionally, the bag body is provided with a side seal, and the width of both the side seal and the partition seal is not less than 1 cm.
[0010] Optionally, the side seal is provided with an easy-tear opening, and the easy-tear opening is triangular in shape.
[0011] Specifically, the easy-tear opening is located on one side of the first powder cavity. The first powder cavity can be torn open through the easy-tear opening. Therefore, after the liquid and powder are mixed, the first powder cavity can be torn open through the easy-tear opening to squeeze out the mixture of oil and powder.
[0012] Optionally, the composite film includes a first PE film layer, a second PE film layer, a nylon film layer, and a PET film layer, with the first PE film layer and the second PE film layer on each side of the nylon film layer, and the PET film layer and the nylon film layer on each side of the first PE film layer.
[0013] Specifically, the PET film layer is located on the outer wall of the bag, while the second PE film layer is located on the inner wall of the bag.
[0014] Optionally, the thickness of the first PE film layer is 15 micrometers to 20 micrometers, and the thickness of the second PE film layer is 40 micrometers to 50 micrometers.
[0015] Optionally, the thickness of the nylon film layer is 15 micrometers to 20 micrometers.
[0016] Optionally, the thickness of the PET film layer is 10 micrometers to 15 micrometers.
[0017] The beneficial effects of this utility model are: the mixing of powder and liquid is achieved by extruding different cavities, and the mixing amount of liquid and powder can also be adjusted by extruding different cavities, and no powder spillage occurs during extrusion and disposal.

[0025] As attached Figure 1 and appendix Figure 2 As shown, a double-layer seasoning packaging bag includes a composite film, which is joined together to form a bag body. The bag body is provided with a dividing seal 3, a longitudinal weak seal 5, a first transverse weak seal 61, and a second transverse weak seal 62. The dividing seal 3, longitudinal weak seal 5, first transverse weak seal 61, and second transverse weak seal 62 divide the space inside the bag body into independent and unconnected liquid chamber 41, first powder chamber 421, second powder chamber 422, and third powder chamber 423. The longitudinal weak seal 5 is located between the first powder chamber 421 and the liquid chamber 41. The first transverse weak seal 61 is located between the first powder chamber 421 and the second powder chamber 422. The second transverse weak seal 62 is located between the second powder chamber 422 and the third powder chamber 423. The width of the longitudinal weak seal 5 is 0.1 mm to 0.2 mm, and the widths of the first transverse weak seal 61 and the second transverse weak seal 62 are 0.1 mm to 0.2 mm.
[0026] In this type of packaging bag, the liquid cavity 41 is used to hold oil, while the first powder cavity 421, the second powder cavity 422, and the third powder cavity 423 are used to hold powder. Since the width of the longitudinal weak seal 5 is 0.1 mm to 0.2 mm, and the widths of the first transverse weak seal 61 and the second transverse weak seal 62 are also 0.1 mm to 0.2 mm, the heat seal strength of the longitudinal weak seal 5, the first transverse weak seal 61, and the second transverse weak seal 62 is relatively weak. When the cavity is squeezed, the gas or liquid inside the cavity will break the heat seal of the weak seal, thus achieving connection. Therefore, squeezing the liquid chamber 41 can cause the longitudinal weak seal 5 to break, thereby allowing the oil to mix with the powder in the first powder chamber 421. When squeezing the first powder chamber 421, the first airflow weak seal and the longitudinal weak seal 5 can break, thus allowing the powder in the first powder chamber 421 and the second powder chamber 422 to mix with the oil in the liquid chamber 41. When squeezing the second powder chamber 422, the first transverse weak seal 61 and the second transverse weak seal 62 can break, thus allowing the powder in the first powder chamber 421, the second powder chamber 422 and the third powder chamber 423 to be completely mixed. Therefore, in this type of packaging bag, the mixing of liquid and powder, as well as the amount of liquid and powder to be mixed, can be achieved by squeezing different cavities. After the mixing is completed, the corresponding cavity can be cut open to squeeze out the mixture. When the liquid and powder are mixed, the mixture is squeezed out again. This can avoid the powder from spilling out during the extrusion process. At the same time, the corresponding cavity can be squeezed according to the needs to achieve the required amount of powder. The unused powder remains in the sealed state to prevent the powder from spilling to other places when discarded.
[0027] In summary, this type of packaging bag can mix powder and liquid by squeezing different cavities, and the amount of liquid and powder mixed can also be adjusted by squeezing different cavities. No powder spillage will occur during extrusion and disposal.
[0028] This type of packaging bag can be considered as consisting of two pieces as shown in the attached image. Figure 2 The composite film shown is heat-sealed, wherein it contains... Figure 2 The shaded and black-lined areas are the heat-sealing bonding areas. The bag's condition immediately after preparation is shown in the attached image. Figure 2 As shown, the liquid chamber 41, the first powder chamber 421, the second powder chamber 422, and the third powder chamber 423 are all in an open state. After the liquid and powder are filled, heat sealing is performed on both ends to complete the sealing of the liquid chamber 41, the first powder chamber 421, the second powder chamber 422, and the third powder chamber 423 (i.e., heat sealing of the two longitudinal side seals is completed). Figure 2 The image only shows two horizontal side seals.
[0029] As attached Figure 1 and appendix Figure 2As shown, the first transverse weak sealing portion 61 and the second transverse weak sealing portion 62 are in a parallel state, and the longitudinal weak sealing portion 5 is in a state perpendicular to the first transverse weak sealing portion 61 and the second transverse weak sealing portion 62.
[0030] As attached Figure 1 and appendix Figure 2 As shown, the bag body is provided with a side seal 2, and the width of both the side seal 2 and the partition seal 3 is not less than 1 cm.
[0031] As attached Figure 1 and appendix Figure 2 As shown, the side seal 2 is provided with an easy-tear opening, and the easy-tear opening is triangular in shape.
[0032] Specifically, the easy-tear opening is located on one side of the first powder cavity 421. The first powder cavity 421 can be torn open through the easy-tear opening. Therefore, after the liquid and powder are mixed, the first powder cavity 421 can be torn open through the easy-tear opening to squeeze out the mixture of oil and powder.
[0033] As attached Figure 1 and appendix Figure 2 As shown, the composite film includes a first PE film layer 102, a second PE film layer, a nylon film layer 103, and a PET film layer 101. The first PE film layer 102 and the second PE film layer are located on both sides of the nylon film layer 103, and the PET film layer 101 and the nylon film layer 103 are located on both sides of the first PE film layer 102.
[0034] Specifically, the PET film layer 101 is located on the outer wall of the bag, while the second PE film layer is located on the inner wall of the bag.
[0035] As attached Figure 1 and appendix Figure 2 As shown, the thickness of the first PE film layer 102 is 15 micrometers to 20 micrometers, and the thickness of the second PE film layer is 40 micrometers to 50 micrometers.
[0036] As attached Figure 1 and appendix Figure 2 As shown, the thickness of the nylon film 103 is 15 micrometers to 20 micrometers.
[0037] As attached Figure 1 and appendix Figure 2 As shown, the thickness of the PET film layer 101 is 10 micrometers to 15 micrometers.
