Embodiment approach 1

[0039] Such as figure 1 As shown, the present invention provides a tea packaging can, which includes an aluminum can body 1 and an aluminum top cover film 2 sealed and welded to the open end 11 of the aluminum can body, the upper side of the aluminum can body 1 The walls are recessed radially inwardly to form a ring groove 12 .

[0040] Specifically, the material of the aluminum tank body 1 is pure aluminum or aluminum alloy, which is generally cylindrical. The upper end of the aluminum tank body 1 forms an open end 11, and the lower end thereof is sealed. In this embodiment, the outer edge of the opening end 11 of the aluminum can body 1 forms an annular platform 13 radially outward, and the width of the annular platform 13 is 0.5mm-8mm. The open end 11 is provided with an annular platform 13, the purpose of which is to increase the contact area between the aluminum can body 1 and the aluminum top cover film 2 and facilitate welding.

[0041] In this embodiment, the upper s...

Embodiment approach 2

[0046] Such as Figure 1-3 Shown, the present invention also provides a kind of manufacturing method of tea packaging jar, it comprises the following steps:

[0047] a) providing an aluminum tank body, performing spinning processing on the upper side wall of the aluminum tank body 1, so that the upper side wall of the aluminum tank body 1 forms a ring groove 12;

[0048] b) flanging the opening end 11 of the aluminum tank body 1, so that the outer edge of the opening end 11 of the aluminum tank body 1 forms an annular platform 13 radially outward;

[0049] c) performing sandblasting and oxidation treatment on the aluminum tank body 1, and then putting tea leaves in the aluminum tank body 1;

[0050]d) heating the aluminum tank body 1 to a certain preset temperature;

Abstract

The invention discloses a tea packaging tin and a manufacturing method thereof. The tea packaging tin comprises an aluminum tin body and an aluminum top cover film welded to the opening end of the aluminum tin body in a sealing mode. The side wall of the upper portion of the aluminum tin body is recessed inwards in the radial direction to form an annular groove. According to the tea packaging tin and the manufacturing method thereof, the tea packaging tin is made of aluminum, has drop resistance and extrusion resistance, and is reliable in sealing and suitable for one-time brewing, and the problem of a tea surplus is solved.

Description

technical field [0001] The invention relates to a packaging can and a manufacturing method thereof, in particular to a tea packaging jar for holding tea leaves and a manufacturing method thereof. Background technique [0002] China is the first country in the world to discover and cultivate tea. With the development of Chinese tea culture, people's requirements for tea quality have been continuously improved, which has prompted the continuous development and improvement of tea production, packaging, transportation and other processes. Tea is easy to absorb moisture, easy to oxidize, easy to break, and easy to deteriorate. Therefore, tea packaging must be able to perfectly solve the above problems. [0003] The existing tea packaging basically adopts two layers of packaging inside and outside, the inner layer is packed in a vacuum plastic bag to ensure that the tea leaves are protected from light, oxygen, and moisture; the outer layer is packed with hard materials to ensure ...
