DETAILED DESCRIPTION

Below, the embodiments of the present application are described in detail with reference to the accompanying drawings.

In Figure 1, the cover body 1 is provided with an edge 2, and a first pull tab 3 is provided on the inner side of the edge 2. The first pull tab 3 is made integrally with the cover body 1, and the first pull tab 3 and the cover body 1 are connected by a first tear line. The first pull tab 3 is connected to the pull ring 5 by a riveted portion 4 on the side away from the edge 2. The pull ring 5 can be used to tear the first pull tab 3 away from the cover body along the first tear line 31 to form a through opening. The edge 2 is higher than the surface of the easy-open cover 1.

Referring to FIG. 2 , the pull ring 5 is provided with a stress portion 51 at the middle position between the riveted portion 4 and the pull opening 52. The stress portion 51 causes the pull ring 5 to bend downward and to be close to the surface of the cover body 1. Since the pull ring 5 is curved, the position actually in contact with the surface of the cover body 1 is the pull opening 52 of the pull ring 5. When the stress portion 51 of the pull ring 5 is pressed toward the cover body 1 by manpower, the stress portion 51 of the pull ring 5 moves downward and bends upward under the action of the stress portion 51, so that the pull opening 52 of the pull ring 5 partially tilts upward. At this time, the human body can easily open the pull tab 3 by using the pull ring 5. In order to realize the function of the stress portion 51, the pull ring 5 can be made of steel, stainless steel, plastic, or composite materials, etc. It can be made of aluminum alloy materials, plastic materials such as polycarbonate, and composite materials such as carbon fiber composite materials. Although the elasticity of aluminum alloy materials is not as good as that of steel, it still has a certain elasticity and is used in the pull ring 5 of the present application. The pull ring 5 can be made of a variety of different types of materials. For the stress portion 51 of the pull ring 5 made of different materials, different processing methods can be used to obtain stress. For example, the stress portion 51 of the pull ring 5 made of metal can be unevenly heated at different positions of the stress portion 51 to obtain different internal stresses. For the stress portion 51 of the pull ring 5 made of plastic and other materials, different processing lengths can be used to achieve different internal stresses at different positions of the stress portion 51. A strip-shaped seam 513 can be provided between the pre-tensioning portion 511 and the pre-tensioning portion 512 to isolate the pre-tensioning portion 511 and the pre-tensioning portion 512. The mold for manufacturing the pull ring 5 shown in FIG9 can be designed so that the length of the pre-tensioning portion 511 of the stress portion 51 of the manufactured pull ring 5 is greater than the pre-tensioning portions 512 on both sides and is elastically bent, thereby making the pull ring 5 bend to one side as a whole. When an external force is applied to bend the pull ring 5 to the other side, the elastic force of the tension portion 511 is overcome and the elastic force of the pre-tensioning portion 511 is used to keep the pull ring 5 bent to the other side in the opposite direction. See FIG3, FIG8, FIG9, FIG10, FIG11 and FIG12 for understanding the above-mentioned arrangement. In FIG9, between the pre-tensioning portion 511 and the pre-tensioning portion 512, the length of the pre-tensioning portion 511 of the stress portion 51 is greater than the pre-tensioning portions 512 on both sides and is elastically bent. A strip seam 513 is arranged between the force parts 512, and a rivet joint 53 is arranged at one end of the pull ring 5. FIG10 shows the pull ring 5 in an initial state. Referring to FIG11, the pre-tensioning part 511 bends upward, and works together with the pre-tensioning part 512 to bend the pull ring 5 downward. In this state, the pull ring 5 can be close to the easy-open lid body 1. FIG11 is a side schematic diagram thereof. In this state, the pre-tensioning part 511 is pressed downward with force. Under the joint action of the pre-tensioning part 511 and the pre-tensioning part 512, the buckle 52 of the pull ring 5 is partially tilted upward, and the pull ring 5 is in an upwardly bent state as a whole. Referring to FIG12, in this state, the buckle 52 of the pull ring 5 can be kept away from the easy-open lid body 1, so as to facilitate further operation of the pull ring.

Figure 8 is a schematic cross-sectional view of the stress portion of a pull ring of an easy-open lid of the present application; the upper half of the figure shows the state of the pull ring 5 before the stress portion 51 is used, the stress portion 51 is provided with a pre-tensioning portion 511 and pre-tensioning portions 512 arranged on both sides of the pre-tensioning portion 511, and the stress portion 51 is in an arc shape that bends downward toward the lid body 1. When the stress portion 5 is pressed toward the lid body 1, under the joint action of the pre-tensioning portion 511 and the pre-tensioning portions 512 arranged on both sides of the pre-tensioning portion 511, the pull ring 5 bends upward, and the stress portion 51 bends upward away from the lid body 1, see the lower half of Figure 8.

FIG4 is a top schematic diagram of another easy-open lid of the present application before use; in the embodiment of the present figure, the position where the second pull-tab 6 is connected to the pull-ring 5 is set at the position where the second pull-ring 6 is close to the edge 2 of the lid body 1, and the pull-ring 5 and the second pull-tab 6 are connected by a rivet portion 4, which can adopt the riveting setting in the prior art, that is, a small hole is provided on the pull-ring, and a rivet protrusion is integrally provided on the second pull-tab 6, and the rivet protrusion is inserted into the small hole to flatten and lock the small hole, and the pull-ring 5 and the second pull-tab 6 are arranged to be rotatable, referring to FIG5, which shows that the second pull-tab 6 has a ring with a notch, and the notch is provided in the notch. The second pull tab 6 is far away from the edge 2 of the cover body 1. When in use, first press the stress portion 51 of the pull tab 5 to bend the pull tab 5 upward, then rotate the pull tab 5 to rotate to the side of the edge 2 close to the second pull tab 6, pull the pull tab 5 upward to make the second pull tab 6 crack first from the end close to the edge 2, and then continue to pull the pull tab 5 until the notch of the second pull tab 6 is located. Refer to Figure 6, which shows that after the second pull tab 6 is fully opened, pressing the second pull tab 6 can make both the pull tab 5 and the second pull tab 6 close to the surface of the cover body 1, thereby preventing the pull tab 5 and the second pull tab 6 from affecting the use of the easy-open cover.

Figure 7 is an overall schematic diagram of a can of the present application; it includes the above-mentioned cover body 1 and can body 7, the cover body 1 and can body 7 are sealed at the edge 2, the pull ring 5 and the disposable unsealing device are arranged on the side of the cover body 1 close to the edge 2, the bottom of the can body 7 of the can is recessed into the can body 7, which can increase the pressure resistance of the can body 7. When the cans are stacked, the space between the bottom of the upper can and the lower can can accommodate the disposable unsealing device of the lower can. The cover body 1 and can body 7 in this embodiment can be made of aluminum alloy.

The pull ring 5 described in the present application can be provided with a pointed head at one end close to the riveted portion 4. When the pull ring 5 starts to act on the pull tab 3, the pointed head first presses the pull tab 3 to open a small opening along the tear line 31, and then further directly opens the pull tab 3, or rotates the pull ring 5 to further open the pull tab 3. This is the prior art and can be provided on the pull ring 5 of the present application.
