[0002] The safety of food contact materials is closely related to food safety. In order to test the safety of food contact materials, migration tests need to be conducted on food contact materials. 3.3 of the national standard GB 5009.156-2016 clearly states that the object of migration test is the surface that may be in direct contact with food under reasonable expected conditions of use. Therefore, for samples that are in contact with food on one side and the materials on both sides are inconsistent, a migration test cell is required to conduct a single-sided migration test.

[0035] For details, see Figure 3 Unlike the existing migration test pool, the second container 9 of the migration test pool can be disassembled, and the shape of the bottom surface is adapted to the shape of the sample to be tested, that is, the size and dimensions are the same. Since the bottom surface is used as the test surface, the second container 9 can be replaced according to the shape of the sample to be tested, and a bottom surface adapted to the shape of the sample to be tested can be selected, such as a circular, triangular, rectangular, square and other irregular shapes, so as to meet the migration test in a variety of scenarios. In addition, the detachable connection method of the second container 9 includes but is not limited to bolt connection, threaded connection, snap connection, etc.

[0036] In the above embodiment, further, the container also includes a first container 1, the first container 1 and the second container 9 are detachably connected, the lower portion of the first container has a first opening, the interior of the first container 1 has a first cavity, the first container 1 is provided with a liquid injection port 4, the liquid injection port 4 is detachably connected with a cover 2, the upper portion of the second container 9 has a second opening, and the second container 9 has a second cavity; when the first container 1 is connected to the second container 9, the liquid injection port 4, the first cavity, the first opening, the second opening, and the second cavity are connected.

[0037] For details, see Figure 1 and Figure 2 The container of the migration test pool is a split structure, which is divided into a first container 1 and a second container 9. The split design is convenient for cleaning and storage. When a part is damaged, it can be replaced to extend the service life. At the same time, it is convenient for storage and greatly saves storage space. In addition, the detachable connection methods of the first container 1 and the second container 9, the cover 2 and the liquid injection port 4 include but are not limited to threaded connection, snap connection, hinge connection, etc. Therefore, the utility model has a wider scope of application and can test samples of various shapes.

[0040] For details, see Figure 4 and Figure 5 In order to improve the stability of the migration test pool, the base 13 and the pressure cover plate 15 are also used to clamp the container to prevent the container from tipping over during the migration test, thereby causing the migration test to fail. The connector includes but is not limited to components that can be connected, such as buckles, clamps, and screws. For example, when a buckle is used as a connector, two buckles are respectively installed on the two opposite sides of the base 13 and the pressure cover plate 15, and the two buckles are interlocked to clamp the container in the middle; when a clamp is used as a connector, the clamp is embedded in the two outward sides of the base 13 and the pressure cover plate 15 to clamp the container in the middle; when a screw is used as a connector, a corresponding threaded hole is opened on the base 13 or the pressure cover plate 15 to cooperate with the screw thread to clamp the container in the middle. In addition, the clamping assembly also plays a role in protecting the container and the sample.

[0041] As an optional implementation, in some embodiments, the connecting member includes a butterfly nut 11 and a screw 12, a plurality of first notches are formed on the edge of the base 13, a plurality of second notches are formed on the edge of the gland plate 15, the plurality of first notches are opposite to the plurality of second notches, one end of the screw 12 is fixed at the first notch, the other end of the screw 12 passes through the second notch and is threadedly connected to the butterfly nut 11, and the butterfly nut 11 abuts against the gland plate 15. The base 13 and the gland plate 15 are connected by the cooperation of the screw 12 and the butterfly nut 11, and downward pressure is applied to the gland plate 15 by tightening the butterfly nut 11 on the screw 12, thereby clamping the container. The structure is simple and stable, and the operation is simple, and the assembly can be completed without the use of additional tools.
