Description

Technical Field

[0001] This utility model relates to the technical field of vapor phase rust-preventive plastic sealing bags, specifically a vapor phase rust-preventive plastic sealing bag. Background Technology

[0002] Self-sealing bags are packaging bags that can be automatically sealed by pressing. Common types include zipper self-sealing bags, blown-bonded self-sealing bags, etc. Zipper self-sealing bags are also known as resealable bags. There are also zipper bags, sealed bags, zipper bags, and keel bags. They are made of polyethylene and high-pressure linear polyethylene through blown film forming and heat-cutting to make a type of plastic bag that can be sealed.

[0003] However, when items with sharp corners, such as mechanical parts, are placed in sealed bags, and multiple sealed bags containing such items are stored together, these bags are prone to touching each other. When the sharp corners touch each other, the solution can break the sealed bag, causing damage to the bag and allowing air to enter, which will affect the sealing effect.

[0004] In view of the above problems, this utility model is proposed. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a vapor phase rust-preventive plastic sealing bag to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution.

[0007] This utility model provides a vapor phase rust-preventive plastic sealing bag, including an inner bag body and an outer bag body. The upper surface of the inner bag body is open, and the upper surface of the outer bag body is open and provided with a connecting pocket. The outer bag body is fitted around the outer surface of the inner bag body, and the inner surface of the connecting pocket is fixedly connected to the surface above the inner bag body.

[0008] A first one-way valve communicating with the interior of the inner bag is provided above the surface of the inner bag body, a through hole penetrating the connecting pocket is provided above the surface of the connecting pocket, and an annular connecting collar is provided around the through hole above the surface of the connecting pocket.

[0009] The first one-way valve is inserted into the through hole, the connecting collar is fitted on the surface of the first one-way valve, and a second one-way valve communicating with the interior of the outer bag body is provided below the surface of the outer bag body.

[0010] The upper surface of the inner bag has a first serrated opening on one side and a second serrated opening on the other side.

[0011] Preferably, the front and back sides of the inner surface of the outer bag, as well as the left and right sides of the inner surface, are spaced apart from the surface of the inner bag.

[0012] Preferably, both the first and second sawtooth openings are formed by splicing together multiple triangular slots end to end, and the slots of the first and second sawtooth openings are staggered.

[0013] Preferably, the inner diameter of the through hole is the same as the inner diameter of the connecting collar, and the inner diameters of the through hole and the connecting collar are smaller than the outer diameter of the tail end of the first one-way valve.

[0014] Preferably, the through hole, the connecting collar, and the tail end of the first one-way valve are interference-fitted.

[0015] Preferably, the first and second serrated openings are evenly distributed at equal intervals along the length direction of the opening on the upper surface of the inner bag.

[0016] Preferably, the upper ends of the left and right sides of the outer bag body and the lower ends of the left and right sides of the connecting pocket form a stepped transition.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The outer bag is located outside the surface of the inner bag. A connecting pocket is provided at the opening of the upper surface of the outer bag. The connecting pocket is fixedly connected to the surface of the inner bag. In this way, the outer bag is connected to the inner bag through the connecting pocket, and there is a gap between the inner surface of the outer bag and the outer surface of the inner bag.

[0019] The connecting pocket is provided with a through hole, which allows the first one-way valve on the inner bag to pass through. The connecting collar is located on the outer surface of the first one-way valve, so the sealing between the connecting pocket and the first one-way valve is good.

[0020] Place the items that need rust prevention into the inner bag from the top opening. Use a sealing device to seal the two sides of the inner bag opening together. Because the first and second serrated edges are staggered, they melt and connect together in the high-temperature environment of the sealing device, thus completely sealing the opening of the inner bag.

[0021] Using an air extraction device, some air is extracted from the inside of the inner bag through the first one-way valve. This allows the inner surface of the inner bag to adhere to the surface of the rust-proof item. After the rust-proof particles on the inner surface of the inner bag are vaporized, they can adhere to the surface of the rust-proof item more effectively. Then, using an air extraction device, gas is injected into the inside of the outer bag through the second one-way valve. The injected gas is located between the inner and outer bags.

[0022] The inflated gas causes the outer bag to expand, creating an air shield around the rust-proof items. This prevents multiple sealed rust-proof items from directly contacting or colliding with each other when stored together. It also protects the inner bag of each rust-proof item, ensuring that the inner bag remains intact and maintaining a long-term sealing and rust-proof effect. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] like Figure 1-4 As shown, a vapor phase rust-preventive plastic sealing bag includes an inner bag body 1 and an outer bag body 2. The upper surface of the inner bag body 1 is open, and the upper surface of the outer bag body 2 is open and provided with a connecting pocket 21. The outer bag body 2 is fitted around the outer surface of the inner bag body 1, and the inner surface of the connecting pocket 21 is fixedly connected to the surface above the inner bag body 1.

[0031] A first one-way valve 11 communicating with the inside of the inner bag body 1 is provided above the surface of the inner bag body 1. A through hole 211 penetrating the connecting pocket 21 is provided above the surface of the connecting pocket 21. A circular connecting collar 212 is provided around the through hole 211 above the surface of the connecting pocket 21.

[0032] The first check valve 11 is inserted into the through hole 211, and the connecting collar 212 is fitted on the surface of the first check valve 11. A second check valve 22 communicating with the inside of the outer bag body 2 is provided below the surface of the outer bag body 2.

[0033] The upper surface of the inner bag 1 has a first serrated opening 12 on one side of the opening and a second serrated opening 13 on the other side of the opening.

[0034] There is a gap between the front and back sides, the left and right sides of the inner surface of the outer bag 2 and the surface of the inner bag 1.

[0035] The first serrated opening 12 and the second serrated opening 13 are both formed by splicing together multiple triangular slots end to end, and the slots of the first serrated opening 12 and the second serrated opening 13 are staggered.

[0036] The inner diameter of the through hole 211 is the same as the inner diameter of the connecting collar 212. The inner diameters of the through hole 211 and the connecting collar 212 are smaller than the outer diameter of the tail end of the first one-way valve 11.

[0037] The through hole 211, the connecting collar 212 and the tail end of the first one-way valve 11 are interference fit; the first serrated opening 12 and the second serrated opening 13 are evenly distributed at equal intervals along the length direction of the opening on the upper surface of the inner bag body 1; the upper ends of the left and right sides of the outer bag body 2 and the lower ends of the left and right sides of the connecting pocket 21 are in a stepped transition shape.

[0038] In summary: the outer bag 2 is located outside the surface of the inner bag 1. The upper surface of the outer bag 2 is provided with a connecting pocket 21. The connecting pocket 21 is fixedly connected to the surface of the inner bag 1. In this way, the outer bag 2 is connected to the inner bag 1 through the connecting pocket 21, and there is a gap between the inner surface of the outer bag 2 and the outer surface of the inner bag 1.

[0039] The connecting pocket 21 is provided with a through hole 211, which allows the first one-way valve 11 on the inner bag body 1 to pass through. The connecting collar 212 is located on the outer surface of the first one-way valve 11, so the sealing between the connecting pocket 21 and the first one-way valve 11 is good.

[0040] The items requiring rust prevention are placed into the inner bag 1 through the opening on the upper surface. The two sides of the opening of the inner bag 1 are sealed together using a sealing device. Due to the staggered distribution of the first serrated opening 12 and the second serrated opening 13, the first serrated opening 12 and the second serrated opening 13 can melt and connect together in the high-temperature environment of the sealing device, thus completely sealing the opening of the inner bag 1.

[0041] Using an air extraction device, some air is extracted from the inside of the inner bag 1 through the first one-way valve 11, so that the inner surface of the inner bag 1 can adhere to the surface of the rust-proof item. After the rust-proof particles on the inner surface of the inner bag 1 are vaporized, they can adhere to the surface of the rust-proof item more effectively. Then, using an air extraction device, gas is injected into the inside of the outer bag 2 through the second one-way valve 22, so that the injected gas is located between the inner bag 1 and the outer bag 2.

[0042] The inflated gas causes the outer bag 2 to expand, thus creating an air protective shield around the rust-proof items. This prevents multiple sealed rust-proof items from directly contacting or colliding with each other when stored together. It also protects the inner bag 1 of each rust-proof item, ensuring that the inner bag 1 remains intact and maintains a long-term sealing and rust-proof effect.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
