Description

Technical Field

[0001] The utility model relates to a packaging bag, in particular to a detection card packaging bag. Background Art

[0002] A test card is a tool used to detect specific substances. Its types and application fields are wide, including but not limited to drug detection, motherboard fault diagnosis, pesticide residue detection, HIV virus detection and body temperature testing. These test cards usually have specific test sample types and can quickly give test results. Some can even complete the test process within a few minutes. At present, there is a microbial identification and drug sensitivity analysis system test plate, which is one of the test cards. It is used for fungal identification and semi-quantitative analysis of antimicrobial drug MIC. Its storage conditions are 2℃ to 8℃, with a validity period of 12 months, and transportation conditions are 2℃ to 36℃ and within 7 days. In order to meet the light protection requirements of the microbial identification and drug sensitivity analysis system test plate, aluminum foil bags are currently used for packaging. During the packaging production process, we found that due to the large size of the microbial identification and drug sensitivity analysis system test plate, the overall weight is relatively heavier than that of the general small test plate, which makes the test plate easy to move to the bag mouth during the transportation process before the sealing bag mouth, causing the sealing machine to crush the test plate during the sealing. Therefore, it is urgent to develop a packaging bag that can avoid damage to the product when sealing the bag mouth. Utility Model Content

[0005] Furthermore, the connecting piece and the blocking piece are integrally arranged.

[0006] Furthermore, the connecting piece and the blocking piece are combined to form an elastic member.

[0007] Furthermore, the connecting sheet and the blocking sheet are both plastic sheets.

[0008] Furthermore, the bag body is composed of a front aluminum foil composite film and a rear aluminum foil composite film, the front aluminum foil composite film and the rear aluminum foil composite film are overlapped, and the outer end of the front aluminum foil composite film is sealed and connected with the outer end of the rear aluminum foil composite film by heat sealing.

[0009] Furthermore, the barrier structure is disposed on the inner side of the front aluminum foil composite film and the inner side of the rear aluminum foil composite film.

[0010] Furthermore, a tear notch is provided at the bag opening.

[0011] Furthermore, a tear notch is provided on the bag body at one end opposite to the bag opening. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Embodiment 1

[0019] like Figures 1 to 3 As shown, in this embodiment, the utility model includes a bag body 1, the bag body 1 is provided with a bag opening 2, a blocking structure 3 is provided on the inner wall of the bag body 1 and near the bag opening 2, the blocking structure 3 includes a connecting piece 31 connected to the inner wall of the bag body 1 and a blocking piece 32 connected to the connecting piece 31, and the blocking piece 32 is inclined toward the inside of the bag body 1. In this embodiment, the connecting piece 31 and the blocking piece 32 are integrally provided, and the connecting piece 31 and the blocking piece 32 are combined to form an elastic member. Figure 4 As shown, when the detection card a is loaded from the bag opening of the detection card packaging bag, the front end of the detection card a will push open the blocking piece 32. When the detection card a is completely loaded into the detection card packaging bag, the blocking piece 32 of the blocking structure 3 is reset, thereby preventing the detection card a from escaping from the detection card packaging bag, avoiding damage to the detection card a when the bag opening is subsequently sealed.

[0020] In this embodiment, the connecting piece 31 and the blocking piece 32 are both PET plastic sheets. The PET plastic sheet in this embodiment is a PET plastic sheet, which is a plastic sheet made of polyethylene terephthalate, a thermoplastic polyester, and has excellent physical and mechanical properties. Alternatively, the connecting piece 31 and the blocking piece 32 use polyethylene plastic, which has good flexibility and elasticity. In addition, the materials used for the connecting piece 31 and the blocking piece 32 include but are not limited to K-resin, polycarbonate, PETG, PCTA, transparent PP, PBT, transparent ABS, etc. These materials have good flexibility and plasticity and can be bent to a certain extent without breaking. In this embodiment, the thickness of the plastic sheet used for the connecting piece 31 and the blocking piece 32 is between 0.1 mm and 1 mm.

[0021] In this embodiment, the bag body 1 is composed of a front aluminum foil composite film 4 and a rear aluminum foil composite film 5, wherein the front aluminum foil composite film 4 and the rear aluminum foil composite film 5 are overlapped, and the outer end of the front aluminum foil composite film 4 is sealed and connected with the outer end of the rear aluminum foil composite film 5 by heat sealing. The aluminum foil composite film is composed of aluminum foil, coating and substrate, wherein the aluminum foil belongs to a kind of composite film. The coating material of the aluminum foil composite film is varied, including polyester, polyethylene, polypropylene, etc., and the materials of different coatings can meet different packaging requirements. There are also many kinds of substrates, such as polyester, kraft paper, cardboard, foam and other materials. The aluminum foil layer is compounded with other materials to improve the moisture-proof, anti-oxidation, conductivity and other properties of the film. Due to the excellent performance of the aluminum foil composite film, it is widely used in the packaging industry. The aluminum foil composite film can be applied to the packaging of food, cosmetics, medicine and some industrial products, and can effectively prevent moisture, corrosion and ultraviolet damage to ensure product quality.

[0022] In this embodiment, a tear notch 6 is provided at the bag opening 2. In this embodiment, a tear notch 6 is also provided at the end of the bag body 1 opposite to the bag opening 2. The user can easily open the sealed bag body 1 through the tear notch 6, and then can conveniently take out the detection card a.

[0023] Embodiment 2

[0024] As shown Figure 5 and Figure 6As shown, in this embodiment, the difference between this embodiment and the first embodiment is that: in this embodiment, the inner side of the front aluminum foil composite film 4 and the inner side of the rear aluminum foil composite film 5 are both provided with the blocking structure 3. The blocking structure 3 includes a connecting piece 31 connected to the inner wall of the bag body 1 and a blocking piece 32 connected to the connecting piece 31, and the blocking piece 32 is arranged obliquely toward the inside of the bag body 1. In this embodiment, through the design of the two blocking pieces 32, it can be ensured that the detection card a can be blocked when placed in the front and back, avoiding damage to the detection card a when the bag mouth is sealed, and ensuring more stable production.

[0025] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
