Description

Technical Field

[0001] The utility model relates to the technical field of packaging tightness detection of prepackaged products in industries such as food, medicine, and tobacco. Specifically, it relates to a standard component of a packaging container for calibrating the packaging tightness of prepackaged products. Background Technique

[0002] At present, there are many testing methods for the packaging tightness of prepackaged products such as food, medicine, and other prepackaged products represented by cigarettes at home and abroad, mainly covering vacuum attenuation method, bubble test method, tracer marking method, high-voltage discharge method, microbial immersion method, etc. The existing testing methods mostly evaluate the differences in macroscopic state parameters of products under enhanced leakage conditions. The vacuum attenuation method uses the pressure difference feedback under test-limited conditions to represent the packaging tightness, and is a commonly used testing method for packaging tightness, which is widely used in the food and drug and other packaging fields.

[0003] For example, ASTM F2338-09(2020) of the American Society for Testing and Materials and T / CNFIA 177-2023, a food packaging tightness test method jointly formulated by many enterprises in China's food and packaging industries, are both based on this. The vacuum attenuation method is used for non-destructive leak detection testing, and the recorded results are all pressure differences representing the leak state parameters. In the tobacco industry, YQ-JY / T 2-2018 adopts the "negative pressure pumping-water immersion method" by placing the punched cigarette small box in a closed measurement chamber to carry out the test of characterizing the sealing degree of the cigarette small box by the pressure difference. Without damaging the original prepackaged product, starting from the microscopic physical process of gas movement, the non-destructive test of packaging tightness under negative pressure conditions is completed through numerical simulation. This process has high requirements for space and the opening and closing methods of the system. Inventions such as CN201910788793.0, ZL202010318808.X, and ZL202010319660.1 involve using a negative pressure generator to form a vacuum environment in the test chamber to complete the test of the packaging tightness of the sample.

[0004] Currently, when conducting quantitative detection of packaging seal tightness using destructive testing or non-destructive testing, it is usually directly testing the pre-packaged products to be tested, lacking packaging container standard parts, which will cause the following problems: 1. Lack of unified benchmark: Without standard parts as a reference, it is difficult to form a unified comparison benchmark between different tests. This may lead to significant differences in test results between different test methods or different laboratories, affecting the reliability and comparability of data. 2. Reducing evaluation accuracy: Due to the lack of standard parts, it may not be possible to accurately control all variables during the testing process, resulting in test results being affected by other factors unrelated to seal tightness. For example, differences in physical properties such as the thickness, hardness, and elasticity of packaging materials may all affect the test results, thus reducing the evaluation accuracy. 3. Difficulty in repetition and reproduction: Without standard parts as a benchmark, the repeatability and reproducibility of test results will be questioned. This means that when conducting the same test at different times, locations, or conditions, consistent results may not be obtained. This is a serious problem for quality control and product quality certification. 4. Affecting industry standardization: The development of standardization and normalization in the packaging industry requires unified standard parts to support. If standard parts are lacking, it will be difficult to promote the formulation and implementation of industry standards, thus affecting the development level and competitiveness of the entire industry. 5. Increasing test costs and time: Due to the lack of standard parts as a reference, more samples and test times may be required during the testing process to verify the accuracy and reliability of the results. This will increase test costs and time and reduce test efficiency.

[0005] Therefore, to solve these problems, the development and application of packaging container standard parts are of great significance for realizing the quantitative characterization of packaging seal tightness, improving the accuracy, repeatability, and reproducibility of evaluation methods. Standard parts can serve as a unified test benchmark, help control test variables, improve evaluation accuracy, promote the repetition and reproduction of test results, and drive the development of industry standardization and normalization.

[0006] For this reason, the present utility model is proposed. Content of the Utility Model

[0007] The purpose of the present utility model is to provide a packaging container standard component for calibrating the packaging seal tightness of pre-packaged products in view of the deficiencies of the prior art. It can be applied to the technical field of packaging seal tightness detection of pre-packaged products in industries such as food, medicine, and tobacco. The small box standard part that can characterize the packaging seal tightness of pre-packaged products meets the practical needs of quantitative characterization and provides a basic guarantee for optimizing the accuracy, repeatability, and reproducibility of evaluation methods.

[0008] The present utility model is achieved through the following technical solutions:

[0009] In the present utility model, the packaging containers include common packaging containers such as packaging boxes, packaging bottles, and packaging cans.

[0010] In the first aspect of the present utility model, a standard component of a packaging container for calibrating the packaging seal degree of pre-packaged products is provided, which includes a plurality of packaging container standard parts with different apparent leakage areas. Each of the packaging container standard parts includes a packaging container body, a leakage area located on the surface of the packaging container body, and a filler body encapsulated in the packaging container body;

[0011] The plurality of packaging container standard parts are relatively independent of each other;

[0012] The three-dimensional structural dimensions of the packaging container standard part are the same as those of the pre-packaged product to be tested;

[0013] The leakage area is provided with leakage holes for gas to connect the internal space of the packaging container body and the outside world, and the area of the leakage holes is the apparent leakage area of the packaging container standard part;

[0014] The apparent leakage areas of the plurality of packaging container standard parts vary in a gradient manner.

[0015] The leakage holes can be actual visible pores to the naked eye, or a material with natural air permeability can be directly selected as the material of the leakage area, such as high-permeability paper. In this case, there is no need to drill holes separately, and the air permeability holes of the material itself can be directly used as the leakage holes.

[0016] Preferably, in addition to the filler body, the packaging container body further includes a void part.

[0017] Preferably, the void ratio of the packaging container standard part is formed by the void part, and the void ratio of the packaging container standard part is the same as that of the pre-packaged product to be tested.

[0018] Preferably, the surface of the packaging container body is directly used as the leakage area, and leakage holes are drilled in the leakage area, or an auxiliary material with the leakage holes is directly used as the leakage area;

[0019] Both of the above methods can form the leakage holes in the leakage area. However, in actual use, it is relatively difficult to drill holes directly on the surface of the packaging container body. Therefore, it is more inclined to drill holes in the auxiliary material to form the leakage holes first, and then paste the auxiliary material with the leakage holes on the surface of the packaging container body. During the pasting process, in order to ensure better pasting tightness, creases and folding pieces can be formed on the auxiliary material first, and then the folding pieces and the surface of the packaging container body are pasted face to face.

[0020] Preferably, the auxiliary material is a metal plate or other plate-shaped component with a stable structure. The packaging container body material and the leakage zone material can be consistent, or different materials can be used for processing, such as the packaging container body is 3D printed with plastic material, while the auxiliary leakage zone is made of stainless steel with holes.

[0021] Preferably, when the auxiliary material with the leakage hole is directly used as the leakage area, the leakage area is slightly lower than the surface of the packaging container body, so as to facilitate the attachment of the auxiliary material to the packaging container body.

[0022] Preferably, the leakage hole is selected from a circular hole, a diamond hole, a polygonal hole, such as a square hole, a triangular hole, and any shape as long as the area can be measured.

[0023] Preferably, the gradient adjustment of the apparent leakage area of ​​different packaging container standard parts is achieved by adjusting the hole area and / or the number of holes of the leakage holes.

[0024] Preferably, the leakage position of different pre-packaged products to be tested can be adjusted by adjusting the hole position of the leakage hole.

[0025] Preferably, the filler body is formed by filling a filling material, and the filling material has a shape of granules, strips, or blocks.

[0026] Preferably, the filling material is selected from dielectric materials that are not easy to adsorb and desorb gases, including glass, metal or ceramic.

[0027] The second aspect of the utility model provides an application of the packaging container standard component for calibrating the packaging tightness of pre-packaged products described in the first aspect of the utility model, which is used as a standard component in the packaging tightness detection of pre-packaged products in the food, medicine and tobacco industries.

[0028] Compared with the prior art, the utility model has the following beneficial effects:

[0029] 1. The packaging container standard assembly for calibrating the sealing degree of pre-packaged products of the utility model includes a plurality of packaging container standard parts with different apparent leakage areas.

The utility model innovatively proposes to use a group of small box standard parts for quantitative characterization of the sealing degree of pre-packaged products, and the leakage hole area interval of the grouped standard parts can be selected according to the interval of the packaging sealing degree. The standard parts have traceable leakage area values ​​and can be used for daily calibration of pre-packaged product sealing detection equipment.

[0030] 2. The standard packaging container assembly for calibrating the sealing degree of pre-packaged products of the utility model has the following functions and advantages:

[0034] (4) The standard parts of packaging containers are representative: The standard parts of the present utility model can represent the types of prepackaged products in common industries such as food, medicine, and tobacco in the market, including small box packages of different materials, sizes, and sealing methods.

[0035] (5) The standard parts of packaging containers have stability: The sealing performance of the standard parts should be stable and reliable, and can maintain consistent results in multiple tests.

[0036] (6) Easy availability of the standard parts of packaging containers: The standard parts should be easy to produce and obtain, so as to be widely promoted and used in the industry.

The standard parts of packaging containers are an important basic guarantee for realizing the quantitative characterization of packaging seal.

[0038] 3. The packaging container standard components for calibrating the packaging seal of the prepackaged products of the present utility model have high specification consistency, are wear-resistant, and are not prone to performance loss based on the seal due to transfer and multiple uses.

[0063] Embodiment 1

[0064] The following is a further detailed description of the technical solution of the present invention through the specific implementation of the small box packaging sealing degree standard component in the cigarette industry.

[0065] As Figure 1 Shown in the figure is a structural schematic diagram of a small box standard part applicable to the detection / calibration of the sealing degree of cigarette small box packaging. As shown in the figure, the standard part is composed of a box body 1-1, a leakage area 1-2 on the surface of the box body, and a filler body 1-3 inside the box body. The leakage area 1-2 can be directly punched on the surface of the standard part box body (a) or made of an auxiliary material with a punched hole on the surface of the standard part by bonding.

[0066] To ensure the durability of the small box and avoid the loss of sealing degree performance caused by collisions, abrasions and other losses during frequent use, the outer frame material of the standard part is made of metal material or plastic material. To facilitate assembly and forming, if the leakage area uses auxiliary materials, the material can be the same as or different from the material of the outer frame of the box body. For example, it can be an integral structure formed by one-piece cutting of metal material, a plastic structural part formed by one-time molding of a plastic model, or an assembly form in which a box body with an assembly port is assembled together by welding, gluing, etc.

[0067] In the present invention, the leakage area 1-2 is specific positions on the surface of the standard part including leakage holes 1-2-1, and the leakage holes communicate the internal space of the standard part with the outside.

[0068] The auxiliary material of the leakage area is designed to be circular to ensure processing accuracy and convenience.

[0069] In a specific implementation, the leakage area adopts a standard part combination with different hole areas set by the number of single holes to achieve a gradient change in the sealing degree. For example, Figure 2 Shown is a standard part combination that uses the adjustment of the hole area to achieve a gradient change in the sealing degree.

[0070] In a specific implementation, the leakage area adopts a standard part combination with a fixed hole area and the number of holes adjusted to achieve a gradient change in the sealing degree. For example, Figure 3 Shown is a standard part combination with the same single hole area and an increased number of holes to achieve a gradient of leakage area.

[0071] In a specific implementation, the leakage area can be set at a single position or multiple positions on the surface of the standard part. For example, Figure 4 Shown is a display of standard parts with leakage areas arranged at different positions.

[0072] In a specific implementation, the filler inside the standard part is not easy to adsorb and desorb gas, and glass or metal or ceramic material fillers can be selected.

[0073] As Figure 5 And Figure 6 Shown, the filler of the standard part can select a suitable filler form according to the specifications of the pre-packaged product, and adopt block fillers or strip fillers or granular fillers.

[0074] Example 2

[0075] The technical solution of the present utility model will be further described in detail below through the specific implementation manner of the vial packaging sealability standard component in the pharmaceutical industry.

[0076] As Figure 7 is a schematic structural view of a vial standard part for detecting / calibrating the packaging sealability of a vial. As shown in the figure, the standard part is composed of a vial body 7-1, a leakage area 7-2 on the vial body surface, and a filler body 7-3 inside the vial body. Preferably, the leakage area 7-2 can be directly punched on the surface of the standard part vial body (a) or made of auxiliary materials with surface-bonded punching on the standard part.

[0077] The vial body of the standard part is made of glass material, the bottle cap is a sleeve cap, the inner cap is made of plastic material, and the outer cap is made of metal material. In order to facilitate assembly and molding, if the leakage area uses auxiliary materials, whether the same or different from the material of the outer frame of the vial body is selected, such as an integral structure formed by integrally cutting a metal material, or a plastic structural part formed by one-time molding of a plastic model, or an assembly form in which a vial with an assembly port is assembled together by welding, gluing, etc.

[0078] In a specific implementation manner, as Figure 7 shown, the leakage holes are selected from circular holes, rectangular holes, and hexagonal holes.

[0079] In a specific implementation manner, the leakage area is specific positions on the surface of the standard part that include leakage holes, and the leakage holes communicate the internal space of the standard part with the outside.

[0080] The auxiliary material of the leakage area is preferably designed to be circular or square or diamond-shaped to ensure processing accuracy and convenience.

[0081] In a specific implementation manner, the leakage area adopts a combination of standard parts with different hole areas set by the number of single holes to achieve a gradient change in sealability, such as Figure 8 is a combination of standard parts that uses the adjustment of hole area to achieve a gradient change in sealability.

[0082] In a specific implementation manner, the leakage area adopts a combination of standard parts with a fixed hole area and adjustable hole quantity to achieve a gradient change in sealability, such as Figure 9 is a combination of standard parts with the same single-hole area and an increased number of holes to achieve a gradient of leakage area.

[0083] In a specific implementation manner, the filler inside the standard part is selected according to the actual sample filling state of the sample to be tested. The filler should not easily adsorb and desorb gas, and glass or metal or ceramic material fillers can be selected.
