Abstract

The invention relates to a small tea leaf three-piece can. The small tea leaf three-piece can is composed of three parts of a can body, a bottom cover and an upper cover. The small tea leaf three-piece can is made from a tinplate material. The can body of the small tea leaf three-piece can is in a hollow cylinder shape. A reducing neck is arranged on the upper portion of a can opening. A reducing neck is arranged the bottom of the can body. Each reducing neck is connected with the can body by a radian. The cross section of the upper cover is in a convex shape. The tinplate material at an opening of the upper cover is coiled with the cross section being in a circular shape. The top of the upper cover is in a boss shape, the tinplate of the can body is welded into a cylinder through high frequency resistance welding, after flanging of the upper reducing neck and the lower reducing neck, the top cover, the can body and the bottom cover part are sealed through a double seaming technology, and the small tea leaf three-piece can is formed.

Description

technical field [0001] The invention relates to a small three-piece tea can. Background technique [0002] China is the hometown of tea, the birthplace of tea culture, and the place that produces the most tea in the world. As people's living requirements are increasing day by day, the country has also issued relevant standards and regulations in response to the development of the tea market, and tea is also in accordance with food standards. However, the current production technology of tea packaging cans is relatively backward, and most of them are produced by manual simple punching machines and small workshops, which has low production efficiency and large resource consumption. At the same time, there is no way to guarantee the sealing and safety; Tea packaging jars on the market are inconvenient to carry around; therefore, improvements are necessary. Contents of the invention [0003] The purpose of the present invention is to provide a new type of small three-piece t...
