[0026] Figure 1 is a structural schematic view of the utility model.

[0027] Mark: tank body-1, convex ring-2, ring groove-3, adhesive layer-4, cover film-5, tab-6, convex boss-7, tank bottom-8, sealing layer-51, tear-resistant layer-52. DETAILED DESCRIPTION Example 1:

[0028] As Figure 1The embodiment provides a convenient opening type Buddha jumps over the wall can, and the Buddha jumps over the wall can comprises a can body 1, a convex ring 2, a cover film 5 and a tab 6.

[0029] The can body 1 has a headspace inner cavity (the inner cavity is formed by embedding into the can body 1 at the middle of the top end of the can body 1);

[0030] The convex ring 2 is fixedly arranged in the can body 1, and a containing cavity is formed between the lower end of the convex ring 2 and the inner wall of the can body 1; only the inner side of the convex ring 2 and the containing cavity are communicated at the top end of the can body 1 (as shown in the figure, the outer periphery of the convex ring 2 is fixed to the upper part of the inner cavity of the can body 1, and the convex ring 2 can be integrally formed with the can body 1 to simplify the manufacturing process, and the material can be tinplate or the like); the top end of the can body 1 needs to pass through the inner cavity and the convex ring 2 downwards to enter the containing cavity, and the containing cavity is a space for loading Buddha jumps over the wall food;

[0031] The cover film 5 is fixedly arranged on the top end of the convex ring 2 by heat sealing to cover the inner side of the convex ring 2, and the cover film 5 and the convex ring 2 are fixed by heat sealing process or the like at the top end of the convex ring 2;

[0032] The tab 6 is fixedly arranged on the outer periphery of the cover film 5 (as Figure 1 shown in the figure, the tab 6 at the left end of the cover film 5, when opened, only needs to be gripped and applied with force to the right to tear the cover film 5, so that the can is conveniently opened);

[0033] Further comprising a ring groove 3 arranged at the top end of the convex ring 2;

[0034] The adhesive layer 4 (the adhesive layer 4 can be water-based polyurethane adhesive or solvent-free polyurethane adhesive, and the like, which is environmentally friendly and safe) is arranged in the ring groove 3, and the cover film 5 is fixedly arranged on the top end of the convex ring 2 by heat sealing through the adhesive layer 4 (the placement position of the adhesive layer 4 is thus improved, the application amount of the adhesive layer 4 is increased, the bonding area is increased, and the connection strength between the cover film 5 and the convex ring 2 is improved);

[0035] The tab 6 is integrally formed on the outer periphery of the cover film 5, has good integrity and strong connection;

[0036] The inner ring lower end of the convex ring 2 is transitionally connected to the inner wall of the inner cavity (as Figure 1 shown in the figure, the inner ring end of the convex ring 2 is gradually expanded from top to bottom, and the inner ring lower end is at the same transition height as the inner wall of the inner cavity, so that when the Buddha jumps over the wall food in the can body 1 is poured out, the bottom end of the convex ring 2 does not block the Buddha jumps over the wall food, and the food is not difficult to pour out);

[0037] The cover film 5 comprises a sealing layer 51 fixedly arranged on the top end of the convex ring 2 and a tear-resistant layer 52 fixedly arranged on the top end of the sealing layer 51 (the strength of the cover film 5 during use is improved, and the possibility of rupture is reduced).

[0038] The sealing layer 51 is an aluminum foil layer (Al) or the like. The aluminum foil layer provides excellent barrier properties and can effectively block light, oxygen, moisture, etc., thereby improving the shelf life of the packaging.

[0039] The tear-resistant layer 52 is a polyamide (PA) layer, etc. The polyamide layer has high mechanical strength, excellent puncture resistance and good barrier properties. Example 2:

[0040] like Figure 1 As shown, the difference between this and embodiment 1 is that it also includes several sets of protrusions 7 fixed at the inner ring end of the protruding ring 2, and the top of the protrusion 7 is attached and fixed to the sealing layer 51 (as shown in the figure, the protrusion 7 is fixed on the inner ring end of the protruding ring 2, which can also be integrally formed for easy manufacturing), so as to increase the heat bonding surface of the cover film 5 and further improve the connection strength.

[0041] The boss 7 is provided in multiple sets and is evenly distributed at the inner ring end of the boss ring 2. The multiple sets are provided to improve the connection strength. The reasonable distribution position provides a uniform increase in overall strength and good stability. Example 3:

[0042] like Figure 1 As shown, the difference between it and embodiment 2 is that: the bottom of the tank 1 is provided with a tank bottom 8 for placing and supporting the tank 1;

[0043] When the protrusion 6 is bent and attached to the top of the cover film 5, a recessed groove is formed between the top of the protrusion 6 and the top of the inner cavity. The protrusion 6 can be folded at the position where it is connected to the cover film 5 and then attached to the top of the cover film 5. At this time, the top of the protrusion 6 is lower than the top of the inner cavity, that is, a recessed groove with a height difference is formed between the top of the inner cavity and the top of the protrusion 6.

[0044] The bottom of the can is movably supported in the sinking trough. Two or more sets of the cans can be taken, and after one set is placed stably, the bottom of the other set of cans is placed into the sinking trough. In this way, multiple sets can be stacked.

[0045] When the bottom of the can 8 is centered above the top of the convex ring 2, the outer periphery of the bottom of the can 8 is above the convex ring 2 and / or the boss 7. According to the above, when stacking, the bottom of the bottom of the can 8 is above the convex ring 2 and / or the boss 7. That is, when the bottom of the can 8 is placed in the sinking trough, it is supported by the convex ring 2 and / or the boss 7, which improves the support strength and protects the cover film 5.

[0046] The basic principle and main features of the present application and the advantages of the present application are shown and described above, for those skilled in the art, obviously the present application is not limited to the details of the above exemplary embodiments, and can be realized in other specific forms without departing from the spirit or basic characteristics of the present application.
