Inspection Standards:
1. Capacity: On the one hand, the capacity of the insulated container can hold enough items. On the other hand, it is directly related to the holding temperature, that is, the same caliber, the larger the capacity, the higher the holding temperature. Therefore, the positive and negative deviations of the capacity of the insulated container cannot be too large.
2. Hot water leakage: This project involves the use of safety and affects the beauty of the use environment. When the problem of this project is serious, as long as the thermos bottle filled with water is lifted, hot water will leak between the bladder and the shell, and the user will be burned if the amount is large. Even if the amount is small, it will leak water on the table and the floor, affecting the environment Beautiful.
3. Impact resistance: This item is related to the service life of the product. During the use of the product, bumps are unavoidable. If the materials used in the product accessories have poor shock resistance or the accuracy of the accessories is insufficient, there will be a gap between the bottle liner and the shell. Shaking and bumps in use may cause stone damage. Cotton pad displacement and cracks in the small tail affect the product’s thermal insulation performance. In severe cases, it can cause cracks and even breakage of the bottle liner.
4. Identification: National standards stipulate that the product name, capacity, caliber, manufacturer’s name and address, the standard number used, the method of use, and the precautions in use must be clearly marked.
Precautions:
1. Appearance. The beautiful shape of the insulation cup will be attractive, of course, it depends on the technology of the insulation cup, the details of the workmanship, whether the interface will be delicate, whether the edge of the insulation cup will be smooth and flat. An exquisitely crafted insulation cup represents the importance that manufacturers place on product quality.
2. Material. Stainless steel insulation cups must be food-grade 304 stainless steel. It is best to use 304 steel for the inner tank to ensure that the amount of heavy metals dissolved in the insulation cup used for water does not exceed the standard, including lead. The amount of heavy metals dissolved in the cheap 201 or 202 stainless steel cup is more than 100 times that of 304 steel. The outer shell is irrelevant. Both inside and outside are made of 304 steel. The inner cover is plastic. It is easy to identify. It smells odorless. The best is the PC material. The PC material is boiled in boiling water and has no taste and will not deform.
3. Look at the inner cover. The inner lid of a good insulated cup is normally made of PC material, it smells no taste, and the plastic has good brightness and flatness. The lid should be easy to clear, and there should be no sanitary blind spots that cannot be cleaned, so that it can be cleaned and used.
4. Twist the lid. A good quality thermos cup should be quite smooth and smooth when twisting the lid, with a uniform 360-degree rotation. The thermos cup is used to drink water. It must be opened and tightened several times a day. If the cap is twisted at the beginning, it will be uneven in weight or make a harsh sound. Such a thermos cup will not be used for a long time.
