Dry powder tank packaging cover and matched production die

Abstract

A dry powder tank packaging cover comprises an upper cover body and a lower cover body, the rear side of the upper cover body is connected with the rear side of the lower cover body through a connecting mechanism, the upper cover body is provided with two pairs of symmetric straight edges, the ends of the adjacent straight edges are transited through transition sections, the lower cover body is provided with a circular bottom cover, and the upper cover body is transited from a rectangle to a circle of the lower cover in an arc manner. The tank cover is provided with square cover bodies, the straight edges between the cover bodies form a contact surface in the sealing and transporting process, the cover bodies cannot rotate when being positioned on the same horizontal plane, one tank and the other tank cannot rotate, the upper cover body and the lower cover body project, so that the distance between tank bodies is formed, sealing and transporting stability is improved, sealing by knifecards is replaced, cost is saved, and a packaging type is optimized.

Description

technical field [0001] The invention relates to the field of packaging covers for cans and supporting production equipment, in particular to a packaging cover for dry powder cans and a supporting production mold. Background technique [0002] Dry powder cans are mainly used for placing milk powder, rice flour and powdered health care products or other materials. In actual use, the top of the dry powder can is opened and closed with a plastic can lid. In actual use, since the can body is a cylinder, it is easy to transport after placement. In the event of shaking, due to external force and shaking and collision, it is easy to cause scratches, abrasions, deflated cans, etc. on the appearance of the product packaging, resulting in economic losses caused by product overflow. Trouble, since the general tank body is mainly cylindrical and difficult to change, it is necessary to design a corresponding can packaging cover so that the cover cannot be rotated on the same horizontal pl...

[0002] Dry powder cans are mainly used for placing milk powder, rice flour and powdered health care products or other materials. In actual use, the top of the dry powder can is opened and closed with a plastic can lid. In actual use, since the can body is a cylinder, it is easy to transport after placement. In the event of shaking, due to external force and shaking and collision, it is easy to cause scratches, abrasions, deflated cans, etc. on the appearance of the product packaging, resulting in economic losses caused by product overflow. Trouble, since the general tank body is mainly cylindrical and difficult to change, it is necessary to design a corresponding can packaging cover so that the cover cannot be rotated on the same horizontal plane, so that the cans will not rotate between the cans, and the lids protrude to form a can The distance between bodies increases the stability of packaging and transportation, replacing the link of packaging and using knife cards
