Problems solved by technology

[0006] However, the situation of this type of product still has the following disadvantages: in order to form the groove 100c, not only the forging process but also the metal working process are required to clamp the plastic-molded locking member 200 into the groove 100c of the container 100, and to combine it It is necessary to increase the assembly process, and if it cannot be tightly combined due to carelessness in the operation, there will be penetration in the cracks
[0007] Then, in order to maintain its airtightness, a certain amount of processing technology is required, so it can only be provided (sold) at a high price to a certain extent.

Embodiment Construction

[0029] The following is a preferred implementation example of the present invention, and the metal container with locking parts of the present invention will be further described with reference to the accompanying drawings:

[0030] Such as figure 1 , Figure 1a and Figure 1b As shown, the metal container of the present invention forms the inner space 1 in the center through the metal plate forging process, and after the upper side end of the inner space 1 is extended outward and horizontally bends to form the protruding edge 2, it is injected by embedding. The molding process forms the locking part 4, and the locking part 4 wraps the upper and lower outer sides of the above-mentioned protruding edge part 2, and the whole container 20 is formed into one body, so that the locking part 4 is avoided on the protruding edge part 2. An arbitrary separation occurs.

[0031] At this time, the lock member 4 in the present invention is constituted as follows: Figure 9 As shown, r...

Abstract

The invention discloses a metal container with a locking member, relates to the content related to a plastic lid and a combinable metal enclosed container comprising a locking member, especially improves the manufacturing process of the container, reduces the manufacturing cost greatly, and achieves a more excellent sealing force when combining the metal enclosed container with the plastic lid. Generally, when a locking member is added into a metal enclosed container, the manufacturing process needs a large number of work processes. In this condition, when no additional pre-treatment process exists, quite a lot of technical difficulties exist especially when manufacturing a foursquare shaped product, therefore the container is not easily produced. The metal container of the invention is manufactured by anone-time forging and stamping process and an one-time ejaculation process; and achieves the advantages of simple manufacturing, easy ejaculation moulding and excellent air-tightness.

Description

technical field [0001] The invention relates to an airtight metal container with a locking part, in particular to a manufacturing process of forming the sealing part from the outside of the upper end of the container. Compared with the past, this process not only greatly shortens the production process, but also greatly reduces the manufacturing cost, and can maintain its excellent airtightness. technical background [0002] Usually considering the sanitation of the airtight metal container with locking parts, the metal container must be processed by annealing, but the characteristics of the metal after annealing have brought difficulties to the forging process. A metal container with a locking part is different from a general container in that when it is combined with a lid, the sealing function of the lid and the locking part is tightly combined to maintain the airtightness of its contents. Such as Figure 11 As shown, in the prior art, a combination groove 100c is formed...
