Aluminum thin-wall screw beverage bottle and manufacturing method thereof

Abstract

The invention discloses an aluminum thin-wall screw beverage bottle. The aluminum thin-wall screw beverage bottle comprises a bottle bottom (1), a bottle cylinder (2), a bottle shoulder (3), a bottle neck (4) and a bottle cover (5), wherein the bottle bottom (1) comprises a recess part (1-1) and a supporting part (1-2); the recess part (1-1) is recessed into the bottle; the supporting part (1-2) is used for supporting a bottle body; the first diameter (R1) of the bottom of the recess part (1-1) is greater than the second diameter (R2) of the top of the recess part (1-1); the supporting part (1-2) encircles the bottle bottom for a circle to form an annular shape; the thickness of the bottle bottom (1) is 0.25-0.70mm; the thickness of each of the bottle cylinder (2), the bottle shoulder (3) and the bottle neck (4) is 0.02-0.08m; an annular groove (4-1), an annular convex edge (4-2) and an external thread (4-3) are sequentially formed in the bottle neck (4) from bottom to top; a bottle opening (4-4) is formed in the top of the bottle neck (4) by folded edges.

Description

【Technical field】 [0001] The invention relates to an aluminum thin-wall screw-mouth beverage bottle and a manufacturing method thereof. 【Background technique】 [0002] Aluminum thin-wall screw-top beverage bottle is a packaging container widely used in various industries, and can be used to hold beverages, wine, etc. Thin-wall screw-top beverage bottles are light in weight and easy to carry, easy to operate, safe and reliable, and are very popular among users. [0003] At present, screw-top beverage bottles used in the market are generally made of glass, and glass packaging bottles have the following disadvantages: poor light-shielding performance, and cannot be adapted to the preservation of the filling inside; glass packaging bottles are not easy to print, and usually use labels To indicate that moisture-proof, waterproof and anti-counterfeiting are poor, and at the same time, transportation and storage costs are high. For this reason, people are more willing to use alumi...

AI Technical Summary

Problems solved by technology

[0003] At present, screw-top beverage bottles used in the market are generally made of glass, and glass packaging bottles have the following disadvantages: poor light-shielding performance, and cannot be adapted to the preservation of the filling inside; glass packaging bottles are not easy to print, and usually use labels To indicate that moisture-proof, waterproof and anti-counterfeiting are poor, and at the same time, transportation and storage costs are high. For this reason, people are more willing to use aluminum beverage bottles

Existing aluminum bottles are directly provided with external threads or sleeves with external threads on the outer wall of the bottleneck near the bottle mouth, and the bottleneck part below the threads is not provided with the groove function for installing the anti-counterfeiting lock ring of the bottle cap. The wall thickness and structural pressure capacity are poor, and the bottleneck’s resistance to pressure and twisting is low

In addition, the wall thickness of the existing aluminum thin-walled screw-top beverage bottles is generally greater than 0.65mm, which makes the product use more materials and the manufacturing cost is high.
