Description

Stainless steel heat-insulation cup body

Technical Field

The utility model relates to a thermos cup field specifically, relates to a stainless steel heat preservation cup.

Background

With the improvement of living standard of people, daily drinking water modes and drinking cups are also changed. The stainless steel vacuum cup with heat preservation performance is developed from the traditional appliances such as an enamel jar, a glass cup, a ceramic cup, a purple sand cup and the like. The cup body of the stainless steel vacuum cup is mainly produced by combining an inner layer stainless steel material and an outer layer stainless steel material through a vacuumizing technology. The vacuum structure of the stainless steel vacuum cup can effectively control three heat transfer ways of heat conduction, heat convection and heat radiation so as to achieve the purposes of heat preservation, cold insulation and fresh keeping. Can be used for containing water, tea, coffee, wine, milk or traditional Chinese medicine and the like, and is convenient for the life of people. The heat insulation performance of the vacuum cup is an important index for measuring the quality of the vacuum cup, but the heat insulation performance of the common stainless steel vacuum cup on the market is not ideal.

The tea is a most traditional favorite beverage for Chinese people, and has the effects of preventing aging and promoting health. However, the stainless steel vacuum cup is not suitable for making tea, on one hand, because the tea mainly contains a plurality of vitamins and trace metal elements, namely weak-base tannic acid, the acid-base and the trace metal elements react with metal on the cup wall to generate other heavy metals which are not easy to be absorbed by human bodies after long-term use of the stainless steel cup, and the health of the human bodies is damaged. On the other hand, when the stainless steel vacuum cup is used for making tea, tea stains can be attached to the surface of the cup wall and are not easy to remove, the tea stains contain various harmful substances, and the long-term use of the vacuum cup with the tea stains can seriously harm the human health.

With the improvement of aesthetic appearance of people, the single color of the stainless steel can not meet the requirements of people on the appearance of the vacuum cup, so that people expect to achieve the aim of aesthetic appearance by measures such as spraying paint on the outer wall of the stainless steel vacuum cup, printing various patterns and the like.

Ceramic paint is an aqueous, healthy, environmentally friendly inorganic paint that has been widely used over a decade of development on the surfaces of food contact appliances, such as: the health-care cup is applied to the cup body of a stainless steel vacuum cup, and can meet the requirements of people on health.
