[0067] The inner diameter of the inner cover 3 in the present invention is the same as the inner diameter of the currently used ordinary cover, which can meet the requirements of connecting with the existing general packaging containers. It not only has a wide range of applications, but also can directly perform the cap sorting and capping work on the existing beverage filling machine, and can directly complete the sterilization treatment in the existing sterilization equipment, so aseptic filling can be easily achieved.

[0068] In the present invention, the first sealing film opening member 403 and the second sealing film opening member 601 may be, but are not limited to, cutting knives for cutting the sealing film.

[0069] Further, such as Figure 2 , Fig.12 As shown, the first sealing film 5 and the second sealing film 6 are both thin sheet structures arranged in the horizontal direction, the edge of the first sealing film 5 is sealed to the bottom of the storage bin 4, and the edge of the second sealing film 6 is sealed to the inner wall of the inner cover 3. The connection between the first sealing film 5 and the storage bin 4 may be, but not limited to, heat sealing or ultrasonic welding; the connection between the second sealing film 6 and the inner cover 3 may be, but not limited to, heat sealing or ultrasonic welding. The first sealing film 5 and / or the second sealing film 6 may be, but not limited to, made of aluminum foil. Of course, the first sealing film 5 may also be integrally formed with the same material as the storage bin 4, and the second sealing film 6 may also be integrally formed with the same material as the inner cover 3.

[0070] In an optional embodiment of the present invention, Figure 2 , Fig.11 , Fig.12 As shown, a circular cutting portion 602 is provided along the outer edge of the second sealing film 6, and the second sealing film 6 is connected to the inner wall of the inner cover 3 through the cutting portion 602. The thickness of the cutting portion 602 is less than the thickness of the second sealing film 6. In the process of opening the second sealing film 6, the first sealing film opening piece 403 is cut along the cutting portion 602, thereby facilitating the opening of the second sealing film 6 by the first sealing film opening piece 403.

[0071] Further, such as Figure 2 , Fig.11 , Fig.12 As shown, a cutting and opening groove 603 recessed toward the bottom of the second sealing film 6 is provided at the top of the cutting portion 602. In the initial assembly state (or the initial state in which the first sealing film opening piece 403 cuts the second sealing film 6 and the second sealing film opening piece 601 cuts the first sealing film 5), the second sealing film opening piece 601 abuts against the bottom edge of the first sealing film 5, and the first sealing film opening piece 403 is located in the cutting and opening groove 603. The cutting and opening groove 603 is used as the starting position for cutting the second sealing film 6. The first sealing film opening piece 403 cuts the second sealing film 6 along the cutting portion 602 for one circle and returns to the cutting and opening groove 603. The cutting portion 602 located at the cutting and opening groove 603 remains connected to the inner wall of the inner cover 3. The cutting opening groove 603 facilitates positioning of the initial cutting position of the cutting portion 602 of the first sealing film opening piece 403. During the opening process of the second sealing film 6, the first sealing film opening piece 403 will not cut the cutting portion 602 at the cutting opening groove 603, thereby ensuring that the second sealing film 6 remains connected to the inner cover 3 when it is flipped open, thereby preventing the second sealing film 6 from falling off and falling into the packaging container.

[0072] Further, such as Figure 2 , Fig.11 , Fig.12 As shown, when the first sealing film opening piece 403 starts to cut the second sealing film 6, the first sealing film opening piece 403 and the second sealing film opening piece 601 are arranged opposite to each other along the radial direction of the inner cover 3, so that when the first sealing film opening piece 403 cuts the second sealing film 6 for one circle and returns to the cutting and opening groove 603, the side of the second sealing film 6 away from the cutting and opening groove 603 flips downward, and the second sealing film opening piece 601 is separated from the first sealing film 5. The second sealing film opening piece 601 does not complete the cutting of the first sealing film 5 in a full circle, and a connection position is left between the edge of the first sealing film 5 and the bottom edge of the storage bin 4, so that the first sealing film 5 remains connected to the storage bin 4 when it is flipped down and opened, thereby preventing the first sealing film 5 from falling off and falling into the packaging container.

[0073] In an optional embodiment of the present invention, Figure 2 , Figures 4 to 7 , Fig. 9 , Fig.12 As shown, the guide member 101 is a vertically arranged cylindrical shape with an open bottom, the top of the guide member 101 is connected to the top inner wall of the upper cover 1, and a first internal thread 1011 is provided on the inner wall of the guide member 101. In the initial assembly state (the upper cover 1 is not screwed), the storage bin 4 is located in the guide member 101, and a first external thread 402 matching the first internal thread 1011 is provided on the outer wall of the storage bin 4. At this time, the storage bin 4 and the guide member 101 are connected by the first external thread 402 and the first internal thread 1011. Connection; a rotation-stop guide column 201 is provided on the inner wall of the lower cover 2, and a one-way drive stop tooth 404 is provided on the outer wall of the storage bin 4. When the guide member 101 rotates and moves upward with the upper cover 1, one side surface of the rotation-stop guide column 201 abuts against one side surface of the corresponding one-way drive stop tooth 404. The rotation-stop guide column 201 cooperates with the corresponding one-way drive stop tooth 404 to prevent the storage bin 4 from rotating and moving upward with the upper cover 1, thereby cooperating with the first internal thread 1011 and the first external thread 402 to make the storage bin 4 rotate downward in the opposite direction relative to the upper cover 1.

[0074] Further, such as Figure 2 , Figure 4 , Figure 8 , Fig. 9 , Fig.12 As shown, the inner wall of the upper cover 1 is provided with a second internal thread 104, the upper outer wall of the lower cover 2 is provided with a second external thread 204, and the upper cover 1 and the lower cover 2 are connected by the second internal thread 104 and the second external thread 204. The first internal thread 1011 and the first external thread 402 may have a rotation direction opposite to that of the second internal thread 104 and the second external thread 204. Specifically, the anti-rotation guide column 201 has at least a flat surface and an inclined surface opposite to the flat surface. When the upper cover 1 is screwed, driven by the upper cover 1, the one-way drive stop tooth 404 will rotate to a position where it is against the flat surface of the anti-rotation guide column 201 and then stop rotating, so that the storage bin 4 can be limited by the flat surface of the anti-rotation guide column 201 as the upper cover 1 rotates; continue to screw the upper cover 1, because the first internal thread 1011 and the first external thread 402 have a rotation direction opposite to that of the second internal thread 104 and the second external thread 204, when the upper cover 1 is rotated along the rotation direction of the second internal thread 104 and the second external thread 204, the first internal thread 1011 will apply a force opposite to the rotation direction of the upper cover 1 and downward to the first external thread 402, so as to push the one-way drive stop tooth 404 to rotate in the opposite direction and pass over the anti-rotation guide column 201 by the inclined surface of the anti-rotation guide column 201, so that the storage bin 4 rotates downward relative to the upper cover 1.

[0075] Furthermore, the guide member 101 and the upper cover 1 may be, but are not limited to, integrally formed.

[0076] Further, such as Figure 2 , Figures 5 to 7 , Fig. 9 As shown, a plurality of anti-rotation guide columns 201 extending vertically are provided on the inner wall of the lower cover 2, and the plurality of anti-rotation guide columns 201 are evenly and spacedly arranged along the circumference of the lower cover 2, and a plurality of one-way drive retaining teeth 404 are provided on the lower outer wall of the storage bin 4, and the plurality of one-way drive retaining teeth 404 are evenly and spacedly arranged along the circumference of the storage bin 4.

Among them, the first sealing ring 103 and the upper cover 1 can be, but are not limited to, integrally formed.

[0082] In an optional embodiment of the present invention, Figure 2 , Fig.12 As shown, a second sealing ring 302 is provided on the top inner wall of the inner cover 3 along the circumference of the inner cover 3. When the storage cover is placed on the opening of the packaging container, the second sealing ring 302 can fit tightly with the opening of the packaging container, thereby ensuring the sealing of the storage cover and the opening of the packaging container. The second sealing ring 302 and the inner cover 3 can be, but are not limited to, integrally formed.

[0083] In an optional embodiment of the present invention, Figure 2 , Fig.11 , Fig.12 As shown, a third internal thread 301 is provided on the inner wall of the inner cover 3. When the storage cover is arranged at the opening of the packaging container, the storage cover and the packaging container are connected through the third internal thread 301 and the third external thread at the opening of the packaging container.

[0084] During use of the storage cover of the present invention:

[0085] First, the storage bin 4 is filled with the basic raw material 8, and the bottom opening of the storage bin 4 is sealed with the first sealing film 5, and then the storage bin 4 is assembled with the guide member 101 in the upper cover 1 through a threaded structure. After that, the upper cover 1 and the lower cover 2 are assembled through a threaded structure. After the upper cover 1 and the lower cover 2 are assembled, the inner cover 3 is assembled to the inside of the lower cover 2 by pressing, and the inner cover 3 is clamped and fixed inside the lower cover 2. When the upper cover 1, the lower cover 2 and the inner cover 3 are assembled, the second sealing film opening piece 601 is against the bottom edge of the first sealing film 5, and the first sealing film opening piece 403 is located in the cutting opening groove 603, and the cutting opening groove 603 is used as the starting position for cutting the second sealing film 6. When opening, the consumer can directly screw the upper cover 1 counterclockwise. Under the cooperation of the threaded structure between the upper cover 1 and the lower cover 2, the upper cover 1 rotates and moves upward (the connection point between the anti-theft ring 7 and the upper cover 1 is disconnected). At this time, the guide member 101 rotates and moves upward synchronously with the upper cover 1. Under the action of the threaded structure (reverse thread), the storage bin 4 and the guide member 101 rotate in the opposite direction relative to the upper cover 1 and move downward. In the process of the storage bin 4 rotating and moving downward, the first sealing film opening member 403 cuts the second sealing film 6 along the edge of the second sealing film 6. At the same time, the second sealing film opening member 601 cuts the first sealing film 5 along the edge of the first sealing film 5. When the convex block on the inner wall of the upper cover 1 is embedded in the groove on the outer wall of the lower cover 2, the upper cover 1 stops rotating. At this time, the first sealing film 5 and the second sealing film 6 are both cut and turned downward. At this time, the basic raw material 8 in the storage bin 4 falls downward into the packaging container below.

[0086] In one embodiment of the present invention, after the basic raw material 8 is added, the upper cover 1 is continued to be screwed. Due to the limiting effect between the protrusion and the groove, the lower cover and the inner cover 3 are driven to rotate and move upward synchronously with the upper cover 1, and finally the storage cover as a whole is separated from the packaging container, and the consumer can directly drink the beverage in the packaging container through the opening of the packaging container.

[0087] In another embodiment of the present invention, no protrusions are provided on the inner wall of the upper cover 1, and no grooves are provided on the outer wall of the lower cover 2. After the basic raw material 8 is added, continuing to screw the upper cover 1 will separate the upper cover 1 from the lower cover 2. At this time, the lower cover 2, the inner cover 3 and the storage bin 4 will remain at the opening of the packaging container, and the consumer can drink the beverage in the packaging container through the top opening of the lower cover 2.

[0088] The characteristics and advantages of the storage cover of the present invention are:

[0089] 1. In the storage cover, a storage bin 4 and a guide member 101 capable of driving the storage bin 4 to rotate and move downward are arranged in the upper cover 1, a storage space is formed in the storage bin 4, a basic raw material that can be mixed and dissolved with water or a basic solution in a packaging container can be accommodated in the storage space, a first sealing film 5 for sealing the storage space is arranged at the bottom opening of the storage bin 4, an inner cover 3 is arranged in the lower cover 2, and a second sealing film 6 is arranged on the inner cover 3, the first sealing film 5 and the second sealing film 6 have a double sealing effect on the basic raw material, ensuring that the basic raw material is placed in a separate, closed and well-sealed storage space, thereby meeting the requirements of aseptic filling.

[0090] 2. The storage cover has a double-layer sealing structure of the first sealing film 5 and the second sealing film 6. A first sealing film opening piece 403 is provided at the bottom edge of the storage bin 4, and a second sealing film opening piece 601 is provided at the edge of the second sealing film 6. During the screwing process of the upper cover 1, the first sealing film opening piece 403 cuts the second sealing film 6 along the edge of the second sealing film 6, and at the same time, the second sealing film opening piece 601 cuts the first sealing film 5 along the edge of the first sealing film 5. The first sealing film 5 and the second sealing film 6 can be cut synchronously only by screwing the upper cover 1, so that the double-layer sealing structure in the cover body can be opened at the same time, the operation is simpler and the use is more convenient, ensuring that the basic raw materials can fall into the packaging container smoothly, greatly improving the consumer's use experience.

[0091] 3. The inner diameter of the inner cover 3 in the storage cover can be the same as the inner diameter of the currently used ordinary cover, which can meet the requirements of connecting with the existing general packaging containers. It not only has a wide range of applications, but also can directly perform the work of cap sorting and capping on the existing beverage filling machine, and can directly complete the sterilization process in the existing sterilization equipment, so aseptic filling can be easily achieved.
