Abstract
Description
Technical Field
[0001] The invention relates to the technical field of sealing detection of pre-packaged products in the food, medicine, tobacco and other industries, and in particular to the application of a packaging container standard component for calibrating the sealing of pre-packaged products. Background Art
[0002] At present, there are many testing methods for packaging sealing of food, medicine and other pre-packaged products represented by cigarettes at home and abroad, mainly covering vacuum decay method, bubble test method, tracer labeling method, high-voltage discharge method, microbial immersion method, etc. The existing detection methods are mostly for evaluating the differences in macroscopic state parameters of products under enhanced leakage conditions. The vacuum decay method uses the pressure difference value under limited test conditions to feedback the packaging sealing. As a common testing method for packaging sealing, it is widely used in food, medicine and other packaging fields.
[0003] For example, the American Society for Testing and Materials ASTM F2338-09 (2020) and the food packaging airtightness test method T / CNFIA 177-2023 jointly developed by many companies in my country's food and packaging industry are based on this, using the vacuum decay method for non-destructive leak detection tests, and the recorded results are all pressure difference values representing the leakage state parameters. In the tobacco industry, YQ-JY / T 2-2018 uses the "negative pressure extraction-water immersion method" to place the punched cigarette box in a closed measuring chamber to conduct a pressure difference test to characterize the airtightness of the cigarette box. Without destroying the original packaging products, the microscopic physical process of gas movement is used as the starting point to complete the non-destructive test of the packaging sealing under negative pressure conditions through numerical simulation. This process has high requirements on the space and the opening and closing methods of the system. The inventions such as CN201910788793.0, ZL202010318808.X, and ZL202010319660.1 involve the use of a negative pressure generator to form a vacuum environment in the test cabin to complete the test of the sample packaging sealing.
[0004] At present, when using destructive or non-destructive testing to carry out quantitative testing of packaging sealing, the pre-packaged products to be tested are usually tested directly, and there is a lack of 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 large differences in test results between different test methods or different laboratories, affecting the reliability and comparability of the data. 2. Reduced evaluation accuracy: Due to the lack of standard parts, all variables may not be accurately controlled during the test process, resulting in the test results being affected by other non-sealing related factors. For example, differences in physical properties such as thickness, hardness, and elasticity of packaging materials may affect the test results, thereby reducing the accuracy of the evaluation. 3. Difficult to repeat and reproduce: Without standard parts as a benchmark, the repeatability and reproducibility of the test results will be questioned. This means that when the same test is performed at different times, places, or conditions, it may not be possible to obtain consistent results. This is a serious problem for quality control and product quality certification. 4. Impact on industry standardization: The standardization and normalization development of the packaging industry requires the support of unified standard parts. If standard parts are missing, 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. Increase testing costs and time: Due to the lack of standard parts as 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 testing costs and time and reduce testing efficiency.
[0005] Therefore, in order to solve these problems, the development and application of packaging container standard parts is of great significance for achieving quantitative characterization of packaging sealing and improving the accuracy, repeatability and reproducibility of evaluation methods. Standard parts can serve as a unified test benchmark to help control test variables, improve evaluation accuracy, promote the repetition and reproducibility of test results, and promote the standardization and normalization of the industry.
[0006] To this end, the present invention is proposed. Summary of the invention
[0007] The purpose of the present invention is to address the deficiencies in the prior art and provide a packaging container standard component for calibrating the sealing degree of pre-packaged products, which can be applicable to the technical field of pre-packaged product sealing detection in the food, medicine, tobacco and other industries. The small box standard parts that can characterize the sealing degree of pre-packaged products are the actual needs for realizing quantitative characterization and provide a basic guarantee for optimizing the accuracy, repeatability and reproducibility of the evaluation method.
[0008] The present invention is achieved through the following technical solutions:
[0009] The packaging container in the present invention includes commonly used packaging containers such as packaging boxes, packaging bottles, and packaging cans.
[0010] The first aspect of the present invention provides a packaging container standard assembly for calibrating the sealing degree of pre-packaged products, which comprises a plurality of packaging container standard parts with different apparent leakage areas, each of the packaging container standard parts comprising 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 from each other;
[0012] The three-dimensional structural dimensions of the packaging container standard part are consistent with the three-dimensional structural dimensions of the pre-packaged product to be tested;
[0013] The leakage zone is provided with a leakage hole for gas communication between the internal space of the packaging container body and the outside, and the area of the leakage hole 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.
[0015] The leakage holes can be actual pores visible to the naked eye, or naturally breathable materials can be directly selected as the leakage area material, such as high-permeability paper. There is no need to punch holes here, and the material's own breathable holes can be directly used as leakage holes.
[0016] Preferably, the packaging container body further includes a void portion excluding the filler body.
[0017] Preferably, the void ratio of the standard packaging container part is formed by the void portion, and the void ratio of the standard packaging container part is consistent with the void ratio 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 a hole is punched on the leakage surface to form the leakage hole, or an auxiliary material with the leakage hole is directly used as the leakage area;
[0019] Both of the above methods can form the leakage hole in the leakage area, but it is relatively difficult to directly punch a hole on the surface of the packaging container body during actual use, so it is more inclined to first punch a hole on the auxiliary material to form the leakage hole, and then paste the auxiliary material with the leakage hole to the surface of the packaging container body. In order to ensure better sealing during the pasting process, creases and folds can be formed on the auxiliary material first, and then the folds 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 present invention 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 present invention, 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 present invention has the following beneficial effects:
[0029] 1. The packaging container standard assembly for calibrating the sealing degree of pre-packaged products of the present invention comprises a plurality of packaging container standard parts with different apparent leakage areas. The small box standard parts have the characteristic of traceable leakage areas and can be used as standard parts for evaluating the sealing degree of pre-packaged products or for calibrating sealing detection equipment. The present invention innovatively proposes the use of grouped 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 packaging container standard assembly for calibrating the sealing degree of pre-packaged products of the present invention has the following functions and advantages:
[0031] (1) Unified benchmark: Using standard packaging container parts as a test benchmark can ensure comparability and consistency between different tests, thereby improving the accuracy of test results.

[0034] (4) The standard parts of packaging containers are representative: The standard parts of the present invention can represent the types of pre-packaged products commonly found in the food, medicine, tobacco and other industries on the market, including small box packages of different materials, sizes and sealing methods.
[0035] (5) Standard parts for packaging containers should be stable: The sealing performance of standard parts should be stable and reliable, and be able to maintain consistent results in multiple tests.
[0036] (6) Availability of standard parts for packaging containers: Standard parts should be easy to produce and obtain so that they can be widely promoted and used in the industry.
[0037] The small box packaging standard provided by the present invention can not only improve the accuracy and reliability of the evaluation method, but also promote the standardization and normalization of the packaging industry. The packaging container standard is an important basic guarantee for the quantitative characterization of packaging sealing.
[0038] 3.

[0063] Example 1
[0064] The technical solution of the present invention is further described in detail below through the specific implementation of the standard component of the sealing degree of small box packaging in the cigarette industry.
[0065] like Figure 1 The schematic diagram of the structure of a small box standard part for cigarette small box packaging sealing detection / calibration is shown in the figure. 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 made by directly punching holes on the surface of the standard box body (a) or by using auxiliary materials bonded to the surface of the standard part to punch holes.
[0066] In order to ensure the durability of the small box and avoid the loss of sealing performance due to bumps, wear and tear during frequent use, the standard part outer frame material is metal or plastic. In order to facilitate assembly and molding, if the leakage area uses auxiliary materials, the material is the same or different from the material of the outer frame of the box body, such as an integrated structure formed by integral cutting of metal materials, or a plastic structural part formed in one step of a plastic model, or a box body with an assembly port assembled together by welding, gluing, etc.
[0067] In the present invention, the leakage area 1-2 is a specific location on the surface of the standard part including a leakage hole 1-2-1, and the leakage hole connects the internal space of the standard part with the outside.
[0068] The leakage zone auxiliary material is designed to be circular to ensure processing accuracy and convenience.
[0069] In a specific implementation scheme, the leakage zone adopts a combination of standard parts with different hole areas and single hole numbers to achieve a gradient change in sealing degree, such as Figure 2 It is a combination of standard parts that uses the hole area adjustment to achieve a gradient change in sealing degree.
[0070] In a specific implementation scheme, the leakage zone adopts a combination of standard parts with fixed hole area and adjustable hole number to achieve a gradient change in sealing degree, such as Figure 3 To keep the single hole area the same, the number of holes is increased to achieve a standard parts combination with a leakage area gradient.
[0071] In a specific embodiment, the leakage area can be set at a single point or multiple points on the surface of the standard, such as Figure 4 Standard parts display for arranging leakage zones at different locations.
[0072] In a specific implementation scheme, the filler inside the standard part is not easy to adsorb and desorb gas, and glass, metal or ceramic fillers can be selected.
[0073] like Figure 5 and Figure 6 As shown, the standard filler can select a suitable filler form according to the specifications of the pre-packaged product, using block filler, strip filler or granular filler.
[0074] Example 2
[0075] The technical solution of the present invention is further described in detail below through the specific implementation method of the standard sealing component of the vial packaging in the pharmaceutical industry.
[0076] like Figure 7 The schematic diagram of the structure of a vial standard part for testing / calibrating the tightness of vial packaging is shown in the figure. As shown in the figure, the standard part is composed of a bottle body 7-1, a leakage area 7-2 on the surface of the bottle body, and a filler body 7-3 inside the bottle body. Preferably, the leakage area 7-2 can be made by directly punching holes on the surface of the standard bottle body (a) or by using auxiliary materials bonded to the surface of the standard part to punch holes.
[0077] The standard bottle body is made of glass, the bottle cap is a sleeve cap, the inner cap is made of plastic, and the outer cap is made of metal. In order to facilitate assembly and molding, if the leakage area is made of auxiliary materials, the material is the same or different from the material of the outer frame of the bottle body, such as an integrated structure formed by integral cutting of metal materials, or a plastic structural part formed in one step of a plastic model, or a bottle body with an assembly port assembled together by welding, gluing, etc.
[0078] In a specific embodiment, Figure 7 The leakage hole shown is selected from a circular hole, a rectangular hole, and a hexagonal hole.
[0079] In a specific embodiment, the leakage area is a leakage hole at a specific location on the surface of the standard part, and the leakage hole connects the internal space of the standard part and the outside.
[0080] The leakage zone auxiliary material is preferably designed to be circular, square or diamond-shaped to ensure processing accuracy and convenience.
[0081] In a specific implementation scheme, the leakage zone adopts a combination of standard parts with different hole areas and single hole numbers to achieve a gradient change in sealing degree, such as Figure 8 It is a combination of standard parts that uses the hole area adjustment to achieve a gradient change in sealing degree.
[0082] In a specific implementation scheme, the leakage zone adopts a combination of standard parts with fixed hole area and adjustable hole number to achieve a gradient change in sealing degree, such as Fig. 9 To keep the single hole area the same, the number of holes is increased to achieve a standard parts combination with a leakage area gradient.
[0083] In a specific implementation scheme, the internal filler of the standard part is selected according to the actual sample filling state of the sample to be tested. The filler should not be easy to adsorb and desorb gas, and glass, metal or ceramic fillers can be selected.
