Description

Technical Field

[0001] The utility model belongs to the technical field of food microorganism storage, in particular to a food microorganism sample homogenizing bag. Background Art

[0002] In the crucial field of food microbiological testing, every link needs to be treated rigorously. Food microbiological testing is of great significance in ensuring the quality and safety of food. In order to accurately obtain the microbial information in food microbiological samples, the slapping homogenizing bag can effectively homogenize the food microbiological samples so that the food microbiological samples can achieve ideal representativeness and uniformity. The homogenized food microbiological samples are added to the detection enrichment solution for cultivation, laying a solid foundation for subsequent testing work.

[0003] However, in the actual testing process, we are facing some thorny problems. Most of the homogenizing bags we use are single-layer structures. This kind of homogenizing bag is extremely fragile when facing some sharp or hard food microbial samples, and it is easy to break, which leads to frequent spillage and leakage of food microbial samples. In addition, the top of the homogenizing bag is very unstable and easy to slip, which can easily cause the homogenizing bag to fall off when slapped. The homogenizing bag is easily damaged during the slapping process, so when observing food microbial samples, the vision is easily blurred, which is not conducive to observing the food microbial samples in the homogenizing bag.

[0004] What is even more worrying is that in the subsequent culture process, these broken homogenization bags are very likely to leak, spread and other adverse situations, which will undoubtedly greatly increase the biosafety risk. In this way, not only will the accuracy of the test results be seriously affected, but the health of the operators and the environmental safety of the laboratory will also face huge potential threats.

[0005] Therefore, it is necessary to design a food microorganism sample homogenizing bag to solve the above technical problems. Summary of the invention

[0006] In order to solve the above technical problems, the utility model provides a food microorganism sample homogenizing bag.

[0007] The technical solution of the utility model is: a food microorganism sample homogenizing bag, comprising an inner bag, an outer bag and a visualization window, the outer side of the inner bag is fitted with the inner side of the outer bag, a soft lining is provided at the inner bottom of the inner bag, the peripheral side of the visualization window is respectively fitted with the inner bag and the outer bag, and the inner bag and the outer bag are connected at one end away from the soft lining by a sealing strip.

[0008] Preferably, the visualization window is embedded with a concave mirror. Through the visualization window, the condition of the food microorganism sample in the homogenizing bag can be observed in real time. The concave mirror of the visualization window can provide a wider field of view, and tapping the opposite side of the concave mirror can facilitate the operator to accurately understand the state of the food microorganism sample.

[0009] Preferably, lugs are provided on both sides of the outer bag.

[0010] Preferably, the lug surface is provided with anti-skid patterns, or the lug is provided with a grip hole. The provision of the lug is crucial, and compared with directly holding the top of the homogenizing bag with the hand, tapping with the lug can effectively protect the top of the homogenizing bag, and the anti-skid patterns of the lug can increase the friction of holding the homogenizing bag.

[0011] Preferably, the width of the soft lining is the same as the width of the inner bottom of the inner bag, which has good cushioning performance and can effectively prevent the homogenizing bag from being punctured by gravity or sharp samples during the homogenization process.

[0012] Preferably, the width of the soft lining is greater than the width of the sealing strip.

[0013] Preferably, the inner bag is a polyethylene inner bag. The inner bag is made of polyethylene material, which is food grade and non-toxic, ensuring the safety of direct contact with food microbial samples.

[0014] Preferably, the outer bag is a Kevlar outer bag. The outer bag is a Kevlar outer bag, which has extremely high strength and tear resistance, making the homogenizing bag as a whole more sturdy and durable, and can effectively resist damage to the homogenizing bag by external factors.

[0015] Preferably, the soft lining is a polypropylene soft lining.

[0016] Preferably, the thickness of the soft lining is 3-5 mm, which has good buffering performance and can effectively prevent the homogenizing bag from being punctured by gravity or sharp samples during the homogenization process; the soft lining does not absorb moisture and can effectively prevent breakage or deformation.

[0017] Compared with the prior art, the utility model has the following advantages and effects:

[0018] (1) Through the visualization window, the condition of the food microbial sample in the homogenizing bag can be observed in real time. The concave mirror of the visualization window can provide a wider field of view. By tapping the opposite side of the concave mirror, the operator can accurately understand the status of the food microbial sample;

[0019] (2) In order to accurately obtain the microbial information in the food microbial sample, the slapping homogenizing bag can effectively homogenize the food microbial sample so that the food microbial sample can achieve the ideal representativeness and uniformity. The setting of the lug is crucial. Compared with the conventional method of directly holding the top of the homogenizing bag, slapping the lug by hand can effectively protect the top of the homogenizing bag. At the same time, the anti-slip pattern of the lug can increase the friction of holding the homogenizing bag by hand.

[0020] (3) The design of the inner bag and the outer bag makes the homogenizing bag as a whole have good tear resistance and durability; the inner bag is made of polyethylene material, which is food grade and non-toxic, ensuring the safety of direct contact with food microbial samples;

[0021] (3) The outer bag is a Kevlar outer bag, which has extremely high strength and tear resistance, making the homogeneous bag more durable and effectively resisting damage to the homogeneous bag by external factors;

[0022] (4) The soft lining is a polypropylene soft lining with a thickness of 3-5 mm. This has good cushioning properties and can effectively prevent the homogenizing bag from being punctured by gravity or sharp samples during the homogenization process. The soft lining does not absorb moisture and can effectively prevent breakage or deformation. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to enable those skilled in the art to better understand the present invention, the present invention is now further described in conjunction with specific implementation methods.

[0028] Example:

[0029] like Figure 1 to Figure 3 As shown, the utility model provides a food microorganism sample homogenizing bag, including an inner bag 1, an outer bag 2 and a visualization window 3. The outer side of the inner bag 1 is fitted with the inner side of the outer bag 2, a soft lining 4 is provided at the inner bottom of the inner bag 1, and the sides of the visualization window 3 are respectively fitted with the inner bag 1 and the outer bag 2, and the inner bag 1 and the outer bag 2 are connected at one end away from the soft lining 4 by a sealing strip 6.

[0030] Furthermore, a concave mirror is embedded in the visualization window 3. Through the visualization window 3, the condition of the food microorganism sample in the homogenizing bag can be observed in real time. The concave mirror of the visualization window 3 can provide a wider field of view, and tapping the opposite side of the concave mirror can facilitate the operator to accurately understand the state of the food microorganism sample.

[0031] Furthermore, lugs 5 are provided on both sides of the outer bag 2 .

[0032] Furthermore, the surface of the lug 5 is provided with anti-skid patterns, or the lug 5 is provided with a gripping hole. The provision of the lug is very important. Compared with directly holding the top of the homogenizing bag with the hand, tapping with the lug can effectively protect the top of the homogenizing bag. At the same time, the anti-skid patterns of the lug can increase the friction of holding the homogenizing bag.

[0033] Furthermore, the width of the soft liner 4 is the same as the width of the inner bottom of the inner bag 1. This has good cushioning performance and can effectively prevent the homogenizing bag from being punctured by gravity or sharp samples during the homogenization process.

[0034] Furthermore, the width of the soft lining 4 is greater than the width of the sealing strip 6 .

[0035] Furthermore, the inner bag 1 is a polyethylene inner bag.

[0036] Furthermore, the outer bag 2 is a Kevlar outer bag.

[0037] Furthermore, the soft lining 4 is a polypropylene soft lining. The polypropylene soft lining does not absorb moisture and can effectively prevent damage or deformation.

[0038] Furthermore, the thickness of the soft lining 4 is 3-5 mm.

[0039] When the food microorganism sample is placed in the inner bag during use, the soft lining 4 plays an important role in buffering and protecting. The soft lining 4 is made of polypropylene material with a thickness of 3-5mm. This material has good buffering performance and can effectively reduce the impact force caused by gravity or sharp food microorganism samples during the homogenization process to prevent the homogenization bag from being punctured. At the same time, the polypropylene material does not absorb moisture, which can maintain the shape and performance of the soft lining and prevent it from being damaged or deformed due to moisture;

[0040] Through the visualization window 3, the condition of the food microbial sample in the homogenizing bag can be observed in real time. The visualization window 3 is designed as a concave mirror, which can provide a wider field of view, making it easier for operators to accurately understand the status of the food microbial sample;

[0041] The outer bag 2 is made of Kevlar material, which has extremely high strength and tear resistance, making the homogenizing bag more durable and effectively resisting damage to the homogenizing bag by external factors;

[0042] The operator holds the lug 5 and taps it. Compared with directly holding the top of the homogenizing bag, this method can better protect the top of the homogenizing bag and prevent it from falling off during the tapping process. The anti-slip pattern on the surface of the lug 5 increases the friction between the hand and the lug 5, so that the operator can hold the homogenizing bag more firmly and perform a stable tapping operation, so that the food microorganism sample is fully mixed in the homogenizing bag;

[0043] In the subsequent detection and enrichment liquid culture process, the sealing strip 6 plays a key sealing role, ensuring that the food microbial sample in the homogenizing bag will not leak and spread, reducing the biosafety risk. At the same time, the width of the soft liner 4 is the same as the width of the bottom of the inner bag 1, and is greater than the width of the sealing strip 6. This design further improves the stability of the homogenizing bag and makes the homogenizing bag more reliable during use.

[0044] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent changes and modifications made within the scope of the present invention should still fall within the scope of the present invention.
