The utility model discloses a lock bright storing lid and packaging container's use does:

the upper cover 1, the lower cover 2 and the puncture piece 3 are assembled, materials 6 are filled into the storage cavity 201 from the bottom opening of the lower cover 2, and then the bottom opening of the lower cover 2 is sealed by a first sealing film 4, so that the assembly of the fresh-locking storage cover is completed; at the moment, the driving blade 101 below the upper cover 1 extends into the inner side of the puncture piece 3, the root of the driving blade 101 is contacted with the corresponding driving block 301 on the puncture piece 3, and meanwhile, the first sealing ring 104 and the second sealing ring 105 are matched and sealed with the top of the lower cover 2, so that the leakage of the material 6 is avoided; finally, the lower cover 2 is bonded and fixed on the outer wall of the container main body 20, so that the first sealing film 4 is fully attached to the second sealing film 30 at the upper opening of the container main body 20, and the whole filling of the material 6 and the assembly of the container main body 20 are completed.

As shown in fig. 15 and 16, when the first sealing film 4 and the second sealing film 30 are opened, a consumer holds the upper cover 1 and screws the upper cover 1 counterclockwise, at this time, under the action of the thread structure lead between the upper cover 1 and the lower cover 2, the upper cover 1 rotates counterclockwise and moves upward in the vertical direction at the same time, the driving blade 101 located below the upper cover 1 moves synchronously with the upper cover 1 and abuts against the driving block 301 on the puncturing element 3, and under the action of the pressing force of the driving blade 101, the driving block 301 slides along the side edge of the driving blade 101, so that the puncturing element 3 moves in the opposite direction to the upper cover 1, i.e., rotates clockwise and moves downward at the same time (because the acting force of the side edge of the driving blade 101 on the driving block 301 is an oblique force, which can be decomposed into a downward pressing force in the vertical direction and a tangential force in the horizontal direction); the puncturing piece 3 synchronously cuts the first sealing film 4 and the second sealing film 30 along the edges of the first sealing film 4 and the second sealing film 30 in the downward moving process until the guide block 207 on the puncturing piece 3 slides to the top sealing position of the second guide section 3033, the downward moving action of the puncturing piece 3 is stopped, the cutting teeth 302 synchronously cut the first sealing film 4 and the second sealing film 30 at the moment, the first sealing film 4 and the second sealing film 30 which are cut under the downward moving action of the puncturing piece 3 and the gravity action of the material 6 are downwards turned along the still reserved connection point, and the material 6 in the storage cavity 201 also falls into the container main body 20 below along with the downward moving action, so that the opening process of the first sealing film 4 and the second sealing film 30 is completed.

The above description is only exemplary of the present invention, and is not intended to limit the scope of the present invention. Any person skilled in the art should also realize that such equivalent changes and modifications can be made without departing from the spirit and principles of the present invention.
