Abstract
Description
Technical Field
[0001] The present application relates to the field of microbial detection and quality control, and in particular to a packaging box for filter membrane quality control strains. Background Art
[0002] In the field of microbial testing and quality control, filter membrane quality control strains play a crucial role. Filter membrane quality control strains are made by mixing microorganisms with a protective agent, then evenly distributing a specific number of microorganisms on the surface of a microporous filter membrane through spraying or filtration, and then freeze-drying or other methods to fix the microporous filter membrane surface. These strains are characterized by the presence of active microorganisms on the surface of the microporous filter membrane, resulting in a microporous filter membrane with a specific number of microorganisms on its surface.
[0003] However, the current conventional filter membrane packaging forms have many problems in the preservation and transportation of filter membrane quality control strains. On the one hand, conventional packaging will cause the loss of microorganisms due to friction on the filter membrane surface; on the other hand, conventional filter membrane packaging forms are not suitable for the convenient use of filter membrane quality control strains, nor can they achieve complete isolation of filter membrane quality control strains from the external environment. In actual applications, these deficiencies have seriously affected the preservation, transportation integrity and ease of use of filter membrane quality control strains. At the same time, they may also cause microbial loss due to contact with the packaging surface. The contamination of filter membrane quality control strains due to inadequate isolation of the filter membrane quality control strain packaging from the external environment and human operation has limited its application in more scenarios such as culture medium quality control and disinfection effect verification. Utility Model Content
[0004] The purpose of this application is to address the above-mentioned problems existing in the prior art and to provide a packaging box for filter membrane quality control strains.
[0005] In order to achieve the above-mentioned application purpose, the present application adopts the following technical solution: a packaging box for filter membrane quality control strains includes an upper cover and a lower cover, and the lower cover and the upper cover cooperate to form a closed space; the upper cover and the lower cover are both provided with a structure for placing the filter membrane. When the upper cover and the lower cover cooperate, the edge of the filter membrane can be fixed by the structure and avoid the area with strains on the filter membrane.
[0006] Furthermore, the lower cover and / or the upper cover are provided with support ribs capable of supporting the filter membrane.
[0007] Furthermore, it also includes a box body and a push tube for pushing the filter membrane out of the box body. The box body is arranged between the upper cover and the lower cover, and cooperates with the upper and lower covers to form a closed space. The push tube is arranged in the closed space, and the lower cover cooperates with the upper cover through the push tube to fix the filter membrane.
[0008] Furthermore, the maximum outer diameters of the upper cover and the lower cover are both larger than the box body, so as to facilitate the removal of the upper cover and the lower cover.
[0009] Furthermore, a through hole is provided on the upper cover, and a protruding boosting portion is provided on the side of the push tube away from the filter membrane, and the boosting portion passes through the through hole and extends out of the upper cover.
[0010] Furthermore, reinforcing ribs are provided around the boosting portion.
[0011] Furthermore, the portion of the push tube that contacts the box body is provided with an anti-slip structure to prevent the push tube from naturally sliding out of the box body after the upper and lower covers are removed.
[0012] Furthermore, a notch is provided on the lower cover for facilitating removal of the filter membrane.
[0013] Furthermore, the upper cover abuts against the push tube.
[0014] Furthermore, a supporting portion for supporting the filter membrane is provided on the inner wall of the box body, so that the filter membrane can still be retained in the box body after the lower cover is opened.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. Improve storage and transportation quality
[0017] 1. A three-layer design or a two-layer design is adopted, in which the upper cover, the lower cover and the box body (part of the scheme) cooperate to form a closed space. The lower cover has supporting ribs and the bottom of the box body has convex points. These structures can effectively fix the filter membrane with strains and prevent the loss of microorganisms due to friction on the filter membrane surface during storage and transportation.
[0018] 2. The packaging can be vacuumed without affecting the filter membrane quality control strain, further ensuring the stability of the strain during storage and transportation.
[0019] 2. Enhanced ease of use
[0020] 1. For the three-layer design, the filter membrane can be pushed out of the box by pressing the push tube, without the need for tweezers or other tools, making the operation simple and quick.
[0021] 2. The top and bottom covers can be removed separately for ease of use. For example, removing the top cover directly exposes the filter membrane for disinfection verification; removing the bottom cover allows the filter membrane to be attached to the culture medium surface by pressing the push tube for culture.
[0022] 3. For the two-layer design, the lower cover is provided with a notch for taking out the filter membrane, which is convenient for clamping the filter membrane and improves the convenience of operation.
[0023] 3. Ensure environmental isolation and reduce pollution
[0024] 1. Each scheme can form a relatively good closed space, effectively isolating the filter membrane quality control strain from the external environment, and avoiding contamination of the filter membrane quality control strain due to inadequate isolation and human operation.
[0025] 2. When conducting a disinfection effect test, you can first remove the top cover for disinfection. After disinfection is completed, put the top cover back on to isolate environmental interference before performing subsequent operations to ensure the accuracy and reliability of the test.
[0026] 4. Wide applicability
[0027] The various packaging forms of the utility model can meet different usage requirements and are suitable for various scenarios such as culture medium quality control and disinfection effect verification, providing more options for the application of filter membrane quality control strains.

[0035] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms cannot be understood as limiting this application.
[0037] Example 1
[0038] like Figure 1 and Figure 2 As shown, the packaging box for filter membrane quality control strains is mainly composed of two parts: an upper cover 5 and a lower cover 1. The upper cover 5 and the lower cover 1 cooperate to form a seal. The upper cover 5 and the lower cover 1 are provided with supporting ribs. The filter membrane 2 is placed between the ribs of the upper cover 5 and the lower cover 1. The ribs of the upper cover 5 need to avoid the area with strains on the filter membrane 2. If vacuum packaging is required, vacuum can be directly drawn.
[0039] Preferably, to facilitate opening, the upper cover 5 and the lower cover 1 are sealed by a ring of ribs, so the maximum radius of the upper cover 5 and the lower cover 1 is larger than the area where they are connected. In addition, to facilitate removal and clamping of the filter membrane 2, a notch 11 is provided in the lower cover 1.
[0040] When using, if you use it directly, tear open the packaging bag, remove the upper cover 5, and use tweezers to move the filter membrane 2 with the strain to a solid culture medium containing agar for cultivation; if you need to use the filter membrane 2 strain to test the disinfection effect of the disinfectant, remove the upper cover 5 and disinfect the filter membrane 2 with the strain first. After disinfection is completed, use tweezers to move it to a solid culture medium containing agar for cultivation.
[0041] This solution, as the basic solution (two-layer), has the simplest structure and can be packaged using only two components. This packaging box can be directly vacuumed when placed in a packaging bag without affecting the quality control strain of the filter membrane 2. After removing the upper cover 5, the filter membrane 2 is directly exposed for disinfection verification.
[0042] The upper cover 5 and the lower cover 1 can also be connected at the outer edges so that the upper cover 5 can be turned around the connection with the bottom of the box, saving space and facilitating storage.
[0043] Example 2
[0044] like Figure 3 and Figure 4 As shown, based on Example 1, a three-layer design is adopted, with the addition of a box body 3 and a push tube 4. This packaging format primarily consists of four parts: an upper cover 5, a lower cover 1, the box body 3, and a push tube 4. The push tube 4 is installed inside the box body 3, forming a mating fit with the box body 3. The filter membrane 2 containing the strain is placed on the filter membrane 2's gripping point between the push tube 4 and the box body 3. After the upper and lower covers 1 are installed and the upper cover 5 is closed, the packaging bag can be placed. If vacuuming is required, this can be done directly.
[0045] Preferably, the lower cover 1 is provided with supporting ribs, which are consistent with the diameter of the push tube 4, so as to cooperate with the push tube 4 to fix the filter membrane 2 with the strain, and prevent the loss of microorganisms due to friction on the surface of the filter membrane 2 during the storage and transportation of the filter membrane quality control strain. The filter membrane 2 with the strain is directly pushed out by the push tube 4 and placed in the culture medium, avoiding the contamination of the filter membrane 2 quality control strain caused by inadequate isolation from the external environment and human operation. The hollow design inside the push tube 4 facilitates direct contact between the bacterial surface of the filter membrane 2 and the disinfectant. Before cultivation, the strain can be fully contacted with the disinfectant by removing the upper cover 5 and then cultured. The bottom of the box body 3 has an inward convex point (support portion 31), which cooperates with the push tube 4 to achieve the fixation of the filter membrane 2, mainly to prevent the filter membrane 2 from falling off directly after the lower cover 1 is removed. In addition, in order to prevent the push tube 4 from naturally sliding out of the box body 3 after the lower cover 1 or the upper cover 5 is removed, an anti-slip structure 42 is also provided on the outer periphery of the push tube 4, such as an anti-slip rib position or an anti-slip protrusion.
[0046] When using, if it is used directly, after tearing open the packaging bag, remove the lower cover 1, push the middle part of the upper cover 5 (to deform it), which can drive the pushing tube 4 to push the filter membrane 2 with the strain out of the box body 3, and place the filter membrane 2 with the strain on a solid culture medium containing agar for cultivation; if the filter membrane 2 strain needs to be used to test the disinfection effect of the disinfectant, the upper cover 5 can be removed first, and the filter membrane 2 with the strain can be disinfected by placing it on the front. After the disinfection is completed, the upper cover 5 is covered to isolate it from environmental interference. When used after disinfection, the lower cover 1 can be removed again, and the middle part of the upper cover 5 can be pushed to drive the pushing tube 4 to push the filter membrane 2 with the strain out of the box body 3, and the filter membrane 2 with the strain can be placed on a solid culture medium containing agar for cultivation.
[0047] This solution further improves upon the basic solution of Example 1. Both the upper cover 5 and the lower cover 1 can be removed separately. Removing the lower cover 1 not only exposes the filter membrane 2 for disinfection verification, but also allows the filter membrane 2 to be released for quality control strains by pressing, without the need for tweezers or other instruments. Removing the lower cover 1 allows the filter membrane 2 to be attached to the surface of the culture medium by directly pressing the push tube 4 for culturing. This packaging method also allows for direct vacuum extraction when placed in a packaging bag without affecting the quality control strains of the filter membrane 2.
[0048] Example 3
[0049] like Figure 5 and Figure 6 As shown, based on Example 2, further improvements are made, that is, on the basis of maintaining the three-layer structure, a through hole is provided on the upper cover 5, and a boosting portion 41 is provided on the push tube 4. The boosting portion 41 extends out of the upper cover 5 through the through hole, and a reinforcing rib is provided on the outside of the hollow part of the boosting portion 41 to prevent the push tube 4 from deformation. The boosting portion 41 can facilitate the pushing of the tube 4.
[0050] When in use, if used directly, after tearing open the packaging bag, remove the lower cover 1. Because of the support part 31, the filter membrane 2 will not fall directly. Push the circular column (boosting part 41) of the push tube 4 in the middle of the upper cover 5 to push the filter membrane 2 with the strain out of the box body 3, and place the filter membrane 2 with the strain on a solid culture medium containing agar for cultivation; if the filter membrane strain needs to be used to test the disinfection effect of the disinfectant, the upper cover 5 can be removed first, and the filter membrane 2 with the strain can be disinfected by placing it on the front. After the disinfection is completed, the upper cover 5 is covered to isolate it from environmental interference. When used after disinfection, remove the lower cover 1 again, push the circular column of the push tube 4 in the middle of the upper cover 5, drive the push tube 4 to push the filter membrane 2 with the strain out of the box body 3, and place the filter membrane 2 with the strain on a solid culture medium containing agar for cultivation.
[0051] This solution retains the advantages of the solution in Example 2 and can further facilitate operation.
[0052] The parts not described in detail in this application are prior art, so this application does not describe them in detail.
[0053] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.
[0054] Although this document frequently uses terms such as lower cover 1, filter membrane 2, box body 3, push tube 4, upper cover 5, notch 11, support portion 31, push-assisting portion 41, and anti-slip structure 42, the use of other terms is not excluded. These terms are used solely to more conveniently describe and explain the essence of this application; interpreting them as any additional limitations is contrary to the spirit of this application.
[0055] This application is not limited to the above-mentioned optimal implementation method. Anyone can derive various other forms of products based on the inspiration of this application. However, no matter what changes are made in their shape or structure, any technical solution that is the same or similar to that of this application falls within the scope of protection of this application.
