Technical Field
[0001] The utility model belongs to the technical field of packaging cans, and particularly relates to a high-grade tea can packaging structure. Background Art
[0002] Traditional high-grade tea packaging adopts two-layer packaging inside and outside, mainly in the following three ways: The first is that the inner layer is a small packaging can (the amount of tea in each can is prepared for one brewing), and the outer layer is a packaging box; the second is that the inner layer is a small packaging bag (the amount of tea in each bag is prepared for one brewing), and the outer layer is a packaging box; the third way is that the inner layer is a packaging bag and the outer layer is a packaging can.
[0003] Since the usage amount after each opening of the first and second packaging forms is constant and cannot be adjusted according to the personal preference of the user for the strength of the tea, there may be a certain degree of waste problem. High-grade tea needs to avoid waste as much as possible, and the amount taken each time is preferably adjusted according to the personal preference of the user for the strength of the tea. Therefore, it is not suitable to adopt the packaging method of a fixed quantity each time. Generally, the third way is adopted, that is, the inner layer is a completely sealed metal-coated packaging bag, the packaging bag is provided with a sealing line and a hermetic seal line, the outer layer is a packaging can, and the capacity of each bag is expected to be brewed about 6-10 times.
[0004] However, the third packaging method has the following problems: 1. After the inner packaging bag is opened, the tea cannot be taken out completely at one time, and the hermetic seal line of the packaging bag has been torn open. Even if the sealing line is sealed again, it is very difficult to obtain a tight sealing effect; 2. A common outer packaging can is provided with a can lid, a can wall and a can bottom. Among them, the can wall and the can bottom are fixed as a whole, and the can lid is separated from the can wall and forms a seal by tightly fitting the outer diameter of the can lid with the can wall from the radial direction. In this way, if the outer diameter of the can lid and the can wall are too tightly fitted, it will be very difficult to open or close. On the contrary, if the edge of the can lid and the can wall are fitted loosely for easier opening or closing of the can lid, the sealing performance will be affected, and the remaining tea will slightly develop a smell, slightly oxidize, and slightly get damp. For high-grade tea and picky consumers, this is a problem that needs to be overcome; 3. In the traditional tea structure packaging can, no packaging structure with a threaded tightening of the inner and outer cans has been found; this is because, as Figure 1 shown, if a threaded screwing structure is adopted between the outer can lid 23 and the outer can wall 24, due to the limitation of the number of turns of the thread (only about two turns, otherwise it will be very time-consuming to unscrew or tighten), the vertical height of the outer can lid 23 cannot be too high. Therefore, after the outer can lid 23 is unscrewed, the exposed height of the inner can 1 is too short, making it inconvenient to grasp the inner can 1, as Figure 1 shown. Content of the Utility Model
[0005] The purpose of the present utility model is to overcome the above-mentioned drawbacks and provide a high-grade tea can structure, which has an easy opening or closing action and good sealing performance after closing.
[0006] Its purpose can be achieved by the following solution: A high-grade tea packaging can structure, including an inner can, the inner can is provided with an inner tank body and an inner can cover, and is characterized in that it also has an outer can made of plastic material. The outer can includes a circular base and a circular cover. The circular base is located below the circular cover. The circular cover includes a cover top surface and a cover circumferential side wall, and the cover top surface and the cover circumferential side wall are integrally formed; an upwardly protruding annular rib is provided at the edge of the circular base, and the lower end of the cover circumferential side wall is movably screwed to the annular rib of the circular base; the inner can is placed in the can cavity of the outer can.
[0007] A ventilation small hole is provided at the central part of the cover top surface, and an upwardly protruding circular ring wall is formed around the ventilation small hole. The inner diameter of the circular ring wall is 1-3 cm, and the circular ring wall is integrally injection-molded with the circular cover. An external thread is formed on the outer circumference of the circular ring wall, and a sealing cover is screwed onto the circular ring wall using this thread. The space surrounded by the central part of the cover top surface, the circular ring wall, and the sealing cover forms a small chamber for storing desiccant.
[0008] The lower end of the cover circumferential side wall is threadedly connected to the annular rib of the circular base.
[0009] The circular cover is made of transparent plastic.
[0010] The outer diameter of the annular rib is smaller than the diameter of the circular base.
[0011] The present utility model has the following advantages and effects:
[0012] First, the present utility model is provided with an inner and outer double-layer tank body, so that the remaining tea after use can be in a basically sealed environment, avoiding problems such as moisture absorption. Moreover, the sealing performance is guaranteed after closing. In addition, the cover top surface and the cover circumferential side wall are integrally formed, and the lower end of the cover circumferential side wall is connected to the annular rib at the edge of the circular base by a threaded connection or other movable screwing connection forms, so the opening or closing of the outer tank body is easy; the opening method of the outer tank body is to unscrew the circular cover and the annular rib, then move the circular cover away to completely expose the inner can, and then the can cover of the inner can can be opened to expose the tea. During the above tea-taking process, the inner can can remain stationary, and the action is leisurely and generous, highlighting the grade of high-grade tea and its consumers.
[0013] Second, the small chamber is communicated with the outer can cavity and can store desiccant, so that the outer can cavity is kept dry, and thus the inner can cavity is kept dry. Description of the Drawings
