Aluminum variable wall special-shaped packaging tin and manufacturing method thereof

Abstract

The invention discloses an aluminum variable wall special-shaped packaging tin and a manufacturing method thereof. The aluminum variable wall special-shaped packaging tin comprises a tin bottom, a tin barrel, a tin shoulder and a tin opening. The tin barrel is divided into a barrel body lower section, a barrel body middle section and a barrel body upper section, and the wall thickness of the barrel body lower section, the wall thickness of the barrel body middle section and the wall thickness of the barrel body upper section are sequentially increased. An annular groove capable of enabling a user to grab the tin conveniently is formed in the barrel body upper section, and accordingly the hand feeling is more comfortable and firmer. The tin shoulder is conical, a plurality of pits which are recessed inwards are formed in the outer wall of the tin, so that the aluminum variable wall special-shaped packaging tin is overall more attractive, and the visual stereoscopic impression is enhanced. Anti-counterfeiting can also be effectively achieved, and enterprise brands are made to be highlight. The aluminum variable wall special-shaped packaging tin which is simple in manufacturing method, simple in structure, attractive in appearance, convenient to grab, capable of effectively achieving the anti-counterfeiting function and low in production cost and the method for manufacturing the packaging tin are provided.

Description

【Technical field】 [0001] The invention relates to an aluminum variable-wall special-shaped packaging can and a manufacturing method thereof. 【Background technique】 [0002] Packaging can is a kind of packaging container widely used in various industries. It can be used to hold beverages, liquor, etc. When using packaging cans, it is easy to operate, safe and reliable, and is deeply loved by users. [0003] At present, the packaging jars used in the market are generally made of glass. Glass packaging bottles have the following disadvantages: poor light-shielding performance, unable to adapt to the filling in them, and the product grade of glass packaging jars is low, and the added value is low. Glass packaging jars The body is not easy to print, and is usually marked with a label, which has poor anti-counterfeiting. At the same time, the glass packaging is bulky, and the label on the bottle body is moisture-proof and waterproof, which makes transportation and storage costs hi...

Problems solved by technology

[0003] At present, the packaging jars used in the market are generally made of glass. Glass packaging bottles have the following disadvantages: poor light-shielding performance, unable to adapt to the filling in them, and the product grade of glass packaging jars is low, and the added value is low. Glass packaging jars The body is not easy to print, usually marked with a label, which has poor anti-counterfeiting performance. At the same time, the glass packaging is bulky, and the label on the bottle is moisture-proof and water-proof, which makes the transportation and storage costs high.

For this reason, people began to use aluminum packaging cans. The existing aluminum packaging cans generally include: tank bottom, can barrel, can shoulder and can mouth. The thickness of the bottom of the tank punched into the packaging tank needs to ensure the deformation pressure and burst pressure and cannot be changed at will. At the same time, the thickness of the can mouth must ensure the quality of the crimping of the can mouth and cannot be thinned arbitrarily. In meeting the national standard GB / T25164-2010 Under the conditions of deformation pressure and burst pressure, the wall thickness of the can body part of the packaging tank must be surplus. If the wall thickness of the surplus part is thinned, raw materials can be saved, thereby reducing production costs; in addition, the existing packaging tanks do not have hand grips The groove is inconvenient to grasp; therefore, it is necessary to improve the existing packaging cans and their processing methods
