Description

Technical Field

[0001] The utility model relates to the technical field of storage tanks, in particular to a storage tank. Background Art

[0002] Because milk powder contains a variety of nutrients, the processed milk powder is sealed and packed with nitrogen during storage. In order to protect the product from contamination and reduce contamination after opening for consumption, it is necessary to design an effective and reasonable protective cover. The defects in the design of milk powder cans and can lids in the prior art are: (1) The raised points of the can body roll seal and the groove of the lid are used as the sealing structure, with only one seal. The close contact point between the can lid and the can body is too small, resulting in a poor seal and a risk of contamination; (2) The contact area between the raised points of the can body roll seal and the groove of the lid is too small, which can easily cause the can lid to fall off, posing a risk of product contamination. (3) The outer dimensions of the can lid are larger than the outer dimensions of the can body, which can easily cause shaking and scratching during the packaging and transportation process, causing scratches on the product appearance or the can lid to fall off, affecting product quality.

[0003] The utility model with publication number CN218464365U discloses an anti-drop milk powder can assembly, including a can cover, a can body and a milk powder spoon, the can cover includes an upper cover and a lower cover, the milk powder spoon includes a spoon handle and a spoon body, a clamping buckle is fixed on the side wall of the lower cover, the angle formed by the clamping buckle and the inner wall of the lower cover facing the upper cover is an acute angle or a right angle, and a protrusion matched with the clamping buckle is provided on the outer edge of the can body. However, the outer size of the can cover of the anti-drop milk powder can assembly is larger than the outer size of the can body, and it is easy to cause shaking and scratching during the packaging and transportation process, resulting in scratches on the product appearance, or the can cover falling off, affecting the product quality.
