Problems solved by technology

[0005] 1. In the process of hot pressing, the plastic film will be denatured and physically damaged, which will interfere with the subsequent immersion, resulting in inaccurate test results and affecting the accuracy of the test results; 2. The operation is complicated and cumbersome, and must be repeated for each soak Making four-sided sealed bags results in a waste of time and cost; 3. Poor sealing, the soaking solution is volatile, and the test results have large errors

Embodiment 1

[0043] Such as Figure 1 to Figure 3 As shown, a food contact material one-sided soaking device of the present invention includes a sealing cover 1 and a container body 2 for containing the soaking solution, and the sealing cover 1 is detachably arranged on the opening of the container body 2 The storage bottle 2 includes a storage tube 21 and an adjustment body 22 for adjusting the volume of the storage bottle 2. The adjustment body 22 is slidably arranged inside the storage tube 21 or connected to the storage tube through threads. 21 connections. The sealing cover 1 is mainly used to press the food contact material to be tested on the opening end of the container body 2, and at the same time avoid the volatilization of the soaking solution. The sealing cover 1 can be connected to the opening end of the container body 2 through threads, or can Other fastening devices are fastened to the opening end of the container body 2; when testing, first fill the container body 2 with t...

Embodiment 2

[0057] Such as figure 1 , 3 , 4, the difference between this embodiment and the first embodiment is that it also includes a second sealing ring 83 arranged between the sealing cover 1 and the container body 2, the second sealing ring 83 and the first sealing ring 81 Coaxial and adjacently arranged, the sealing cover 1 is provided with a second ring groove 84 for fixing the second sealing ring 83; the second sealing ring 83 is used to further improve the sealing effect of the device, and the second sealing ring 83 is clamped or glued Connected to the second ring groove 84; since the second sealing ring 83 is coaxial and adjacent to the first sealing ring 81, when soaking, the edge of the food contact material to be tested is clamped between the first sealing ring 81 and the second sealing ring. Between the rings 83, thereby greatly improving the sealing effect of the device, further avoiding easy volatilization after soaking, and further reducing measurement errors.

Abstract

The invention relates to the technical field of food contact material detection devices, in particular to a food contact material single-face soaking device. The food contact material single-face soaking device disclosed by the invention comprises a seal cover and an accommodating bottle body for accommodating a soaking solution, wherein the seal cover is detachably arranged at the opening end of the accommodating bottle body; the accommodating bottle body comprises an accommodating pipe body and an adjusting body for adjusting the volume of the accommodating bottle body, and the adjusting body is movably arranged on the accommodating pipe body. According to the food contact material single-face soaking device disclosed by the invention, the volume of the accommodating bottle body can be adjusted by adjusting the relative position of the accommodating pipe body and the adjusting body, the soaking tests of a plurality of groups of soaking solutions with different volumes are conveniently carried out on the soaking material, seal bags with different sizes do not need to be remanufactured compared with a traditional soaking manner, and the soaking area of a measured food contact material is accurate, so that the volume of the soaking solution can be accurately controlled, and the measuring result is little in error.

Description

technical field [0001] The invention relates to the technical field of detection devices for food contact materials, in particular to a single-side soaking device for food contact materials. Background technique [0002] Food contact materials are a crucial link in the food safety system, so ensuring the safety of food contact materials is a prerequisite for ensuring that food is not contaminated during packaging and packaging. Among them, plastic products are a major source of food contact materials. Plastics refer to organic macromolecules obtained by polymerization, polycondensation, polyaddition (or any similar steps) of low molecular weight molecules, or by chemically modifying natural molecules. Other substances can be added to these compounds, so migration will inevitably occur during use, and most food contact materials are in contact with food on one side during use, so it is important to detect the migration of pollutants It involves single-sided detection to avoi...
