Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 to 6 schematically show a multi-sealed package can according to an embodiment of the present invention. As shown in the figure, the device comprises a tank body 1 with a closed bottom and an upper cover 3 which is arranged at the mouth part of the tank body 1 and is connected with the tank body 1 in a sealing mode in a removable mode.
Wherein, a middle cover 2 is arranged between the tank body 1 and the upper cover 3.
The middle cap 2 is a single integrated member, and the lower portion thereof is hermetically connected with the mouth of the can body 1.
The upper part of the middle cover 2 extends to the inner upper side and forms a connecting part 21.
The outer side wall of the connecting part 21 is provided with a thread 211, the inner side wall of the upper cover 3 is provided with a thread 31 matched with the inner side wall, and the connecting part 21 is connected with the upper cover 3 through the thread.
