Description

TECHNICAL FIELD

[0001] The utility model relates to the field of can technology, more specifically to a kind of anti-pressure leakproof food can. BACKGROUND

[0002] Anti-pressure leakproof food can is the key packaging technology to ensure that food remains fresh, safe and unaffected by the external environment during long-term storage.

[0003] The can is generally made of strong materials, such as tinplate (tinplate), aluminum alloy or stainless steel, which are not only corrosion-resistant but also can withstand high pressure processing and external impact during transportation. The seal design: the lid and the body of the can are sealed with double edge sealing technology, forming an airtight and watertight closed environment, effectively preventing air, microorganisms and moisture from penetrating, thereby ensuring the freshness and safety of the contents.

[0004] When it is necessary to enhance the structural stability in order to save the use of materials (using thinner materials), the existing wave-shaped design is generally used at the position of the can body to increase the structural strength of the can body, so that the can is more resistant to external pressure during transportation and storage, and deformation or damage caused by collision or extrusion is reduced. However, when only this structure is used to improve the pressure resistance, there is still a disadvantage of insufficient pressure resistance. SUMMARY

[0005] The utility model aims at: in order to solve the above technical problem, the utility model provides a kind of anti-pressure leakproof food can.

[0006] The utility model discloses a kind of anti-pressure leakproof food cans to achieve the above purposes, and specifically adopt the following technical solutions:

[0007] The utility model provides a kind of anti-pressure leakproof food can, including can body and the bottom top two ends respectively fixed can bottom and can cover, the can body is in upper and lower continuous concave-convex arrangement wave shape, the can body is provided with the inner protruding point of protruding in the inside of can body and the outer protruding point of protruding in the outside of can body, and inner protruding point and outer protruding point are all provided with multiple groups and its even distribution between.

[0008] As a preferred technical solution of the utility model, the wave peak of the wave-shaped can body is arc-shaped.

[0009] As a preferred technical solution of the utility model, the inner protruding point is on the wave peak of the wave-shaped can body towards its outside, and the outer protruding point is on the wave peak of the wave-shaped can body towards its inside.

[0010] As a preferred technical solution of the utility model, the inner protruding point is formed by pressure forming towards the inside of the can body, and the outer protruding point is formed by pressure forming towards the outside of the can body.

[0011] As a preferred technical solution of this utility model, the bottom end of the can is centrally recessed towards the inside of the can body to form a groove, and a folded groove communicating with the inside of the can body is formed between the bottom of the can body and the bottom of the can.

[0012] As a preferred embodiment of this utility model, the bent end of the groove is arc-shaped.

[0013] The beneficial effects of this utility model are as follows:

[0014] The can body 1 is provided with a wave-like pattern of continuous concave and convex shapes, which provides initial pressure resistance. The can body 1 is provided with inner protrusions 4 protruding on the inner side of the can body 1 and outer protrusions 5 protruding on the outer side of the can body 1. Both the inner protrusions 4 and the outer protrusions 5 are provided in multiple sets and are evenly distributed alternately to further improve the bending resistance of the can body 1 and strengthen its pressure resistance. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the structure of this utility model.

[0016] Attached reference numerals: Can body-1, Can bottom-2, Can lid-3, Inner protrusion-4, Outer protrusion-5, Groove-6, Fold-7. Detailed Implementation Example 1:

[0017] like Figure 1 As shown, this embodiment proposes a pressure-resistant and leak-proof food can, including a can body 1 and a can bottom 2 and a can lid 3 fixed at its bottom and top ends respectively. The can bottom 2 is integrally formed at the bottom end of the can body 1, and the can lid 3 is fixed at the top end of the can body 1 (as shown in the figure, the can lid 3 is an easy-open can lid, which is convenient to open).

[0018] The can body 1 has a wave-like shape with continuous concave and convex arrangements (as shown in the figure, the can body 1 is ring-shaped and the waves are oriented vertically, providing initial pressure resistance in the vertical or inward direction of the can body 1).

[0019] The tank body 1 is provided with an inner protrusion 4 protruding on the inner side of the tank body 1 and an outer protrusion 5 protruding on the outer side of the tank body 1. Both the inner protrusion 4 and the outer protrusion 5 are provided in multiple sets and are evenly distributed alternately (to enhance the bending resistance of the tank body 1 when it is bent, enhance the pressure protection, and the even distribution results in good overall strength).

[0020] It can also increase resistance when gripping, thus enhancing stability. Example 2:

[0021] like Figure 1 As shown, the difference between it and Embodiment 1 is that the crest of the wave-shaped can body 1 is arc-shaped, which can provide better force dispersion and improve pressure resistance when subjected to external pressure. Example 3:

[0022] like Figure 1 As shown, the difference from Embodiment 2 is that, furthermore: the inner protrusion 4 is located on the crest of the wavy can body 1 facing outwards, and the outer protrusion 5 is located on the crest of the wavy can body 1 facing inwards (e.g., Figure 1 As shown, an inner protrusion 4 is provided at the point where the wave crest faces outward from the tank body 1. When bending occurs at this point, the inner protrusion 4 can suppress bending. This reasonable placement of the protrusion improves the compressive strength. Similarly, an outer protrusion 5 is provided at the point where the wave crest faces inward from the tank body 1, also to improve compressive strength. Example 4:

[0023] like Figure 1 As shown, the difference between this and embodiment 3 is that: the inner protrusion 4 is formed by pressure on the outside of the can body 1 towards its inner side, and the outer protrusion 5 is formed by pressure on the inside of the can body 1 towards its outer side (when the can body 1 is manufactured, mechanical pressure stamping or other methods are used to directly form the inner protrusion 4 and the outer protrusion 5 on the surface of the can body 1, that is, the inner protrusion 4 and the outer protrusion 5 are generated by the pressure deformation of the can body 1, which is convenient to process). At the same time, the inner protrusion 4 and the outer protrusion 5 can be set simultaneously when forming the wavy pattern, making the manufacturing process simpler. Example 5:

[0024] like Figure 1 As shown, the difference between this embodiment and embodiment 4 is that it further includes a groove 6 formed by the bottom end of the can bottom 2 being recessed inward toward the can body 1, and a folded groove 7 communicating with the inside of the can body 1 is formed between the bottom of the can body 1 and the can bottom 2 (as shown). Figure 1 As shown, the bottom of the tank 2 arches upwards into the tank body 1, forming a bent bottom with the tank body 1, which can improve the strength of the bottom and increase the overall pressure resistance.

[0025] like Figure 1 As shown, the bent end of the groove 7 is arc-shaped, that is, an arc-shaped bending structure is formed between the outer end of the bottom 2 that arches upward and the lower side of the body 1. The structure at this position has good pressure resistance.
