Problems solved by technology

[0003] The purpose of the present invention is to provide a safe and easy-to-open metal packaging container for solving the problem that the metal packaging container in the prior art requires a large opening force during the opening process and the operator is easily injured. Improve the safety of metal packaging containers during opening
[0004] Another purpose of the present invention is to provide a safe and easy-to-open container for solving the problems of the prior art metal packaging container, such as the collapse of the container and the deformation of the neck of the anti-theft ring of the container due to the excessive pressure on the top of the cap during the capping process. Metal packaging containers can greatly reduce problems such as container collapse and container anti-theft ring neck deformation caused by metal packaging containers during the capping process
[0005] The third purpose of the present invention is to provide a safe and easy-to-open metal packaging container, which has a simple structure and a , good sealing characteristics

Embodiment 1

[0035] exist figure 1 figure 2 In the shown embodiment 1, a safe and easy-to-open metal packaging container includes a container body 25 and a twist-off lid. A cylindrical container opening 26 is formed on the packaging container, and external threads are formed on the outer wall of the container opening. The twist-off cover includes a cover top 1 and a cover wall 2 extending downward from the outer edge of the cover top. The lower surface of the cover top is provided with a gasket 3, and the outer periphery of the gasket extends downward integrally. The inner sealing ring 14 abutting against the inner wall of the container mouth rim 13 and the outer sealing ring 15 abutting against the outer wall of the container mouth rim form a downwardly opening sealing groove 16 between the inner sealing ring and the outer sealing ring. The container body is composed of a single layer of metal material, and the rim of the container mouth is made of four layers of metal material folded....

Embodiment 2

[0037] exist Figure 4 In the shown embodiment 2, the connection between the bridging and the upper acute angle is formed with an upper pre-slit 10, the upper pre-slit extends along the circumference of the cover wall and its opening communicates with the slit, and the upper pre-slit is formed on the periphery of the cover wall. The upward length is 15% of the bridging width; the connection between the bridging and the lower acute angle forms a lower pre-split 12, which extends along the circumference of the cover wall and its opening communicates with the slit, and the lower pre-split is in the cover. The circumferential length of the wall is 70% of the upper pre-slit length, and the rest are the same as in Example 1.

Embodiment 3

[0039] exist Figure 5 In the shown embodiment 3, the top surface of the sealing pad corresponding to the upper and lower sides of the sealing groove is provided with a material holding tank 17. The center line of the section coincides, the opening width of the container is 60% of the width of the sealing groove, and the depth of the container is 45% of the opening width of the container; the lower end of the outer surface of the inner sealing ring is provided with a guide arc edge 19 The upper edge of the guiding arc edge is connected with the lower edge of the interference ring. In this embodiment, the height of the cross-section of the inner seal ring is greater than the height of the cross-section of the outer seal ring, and the lower part of the outer surface of the inner seal ring is provided with an interference ring 18 (the left part of the dotted line in the figure), and the interference ring and the bottom of the seal groove The distance between them is greater than...

Abstract

The invention discloses a safe and easily-opened metal packaging container, which comprises a container body and a twist-off cover, wherein the outer wall of the container opening is provided with anexternal thread; the cover wall is provided with an internal thread matched with the external thread, the lower part of the cover wall is provided with two convex rings which are parallel to each other and surround the cover wall, an annular groove is formed between the two convex rings, a plurality of long-strip-shaped notches are formed in the bottom of the annular groove in the circumferentialdirection of the cover wall, the cover wall between the adjacent notches forms a bridge, the bridge is of an obliquely-arranged equal-width structure, an upper acute angle is formed between the rightside of the upper end of the bridge and the notch in the right side of the bridge, and a lower acute angle is formed between the left side of the lower end of the bridge and the notch in the left sideof the bridge. The packaging container disclosed by the invention effectively solves the problems that the packaging container in the prior art needs a great opening force in the opening process andan operator is easy to be injured, greatly facilitates the opening of the packaging container, improves the safety of the opening process and has very high practical value.

Description

technical field [0001] The invention relates to the technical field of packaging containers, in particular to a safe and easy-to-open metal packaging container. Background technique [0002] In the prior art, the bridge on the twist-off cover is usually rectangular in shape and is vertically connected to the anti-theft ring on the twist-off cover. When the cover is turned, the bridge is broken by the torsional force (transverse shear force) generated by the rotation of the cover. That is, only when the bridge is broken, the cover can be turned and opened by twisting. This vertically connected rectangular bridging structure, after being subjected to a large transverse shear force, the material yields and fractures, and the breaking point is basically in the middle of the bridging (see Figure 13 ), the torque required for twisting is relatively large, and the torque required for turning the cover suddenly becomes smaller after the break. Difficulty, because the bridging and ...
