Description

Technical Field

[0001] The present invention relates to the technical field of beverage containers, and further relates to a sterile quantitative bottle cap and bottle, and in particular to a quantitative bottle cap and bottle having a sealed chamber inside the bottle cap that is separately filled with powder, granules or liquid. Background Art

[0002] At present, a bottle cap with a separate sealed storage space is increasingly appearing in the beverage market. The principle of use is as follows: basic raw materials (such as solid powders, concentrates, medicines or probiotics, etc.) are filled into a bottle cap with a separate sealed chamber to achieve storage and preservation of the basic raw materials. The bottle body below the bottle cap and matched with the bottle cap is then equipped with purified water or a basic solution for mixing with or dissolving the basic raw materials. When drinking, the sealed chamber is opened by the switch mechanism provided on the bottle cap, the basic raw materials are put into the basic solution of the bottle body, and after fully shaking, the beverage can be directly drunk. The beverage of the above-mentioned form can be added with no or a small amount of food additives such as preservatives, and its taste and quality efficacy are guaranteed during the shelf life, which is beneficial to the health of the drinker and gives a sense of pure nature and greenness. In addition, when opening the bottle cap by the switch mechanism and completing the entire process of feeding and drinking, the consumer can be given a sense of sight and accomplishment of personally completing the processing of the beverage, which greatly improves the consumer's user experience.

[0003] However, the existing bottle caps with such functions are usually complex in structure. After the bottle caps are assembled, the chamber for storing the basic raw materials has the disadvantages of many gaps and poor sealing. Therefore, the bottle body matched with the bottle cap cannot achieve aseptic filling of the basic solution inside, resulting in that such bottle caps and the bottle body matched with them can only be used in the non-sterile market, which greatly limits the development of such bottle caps and the bottle body matched with them.

[0004] There is currently no effective solution to the problem that the bottle cap with a separate closed storage space in the related art has poor sealing performance and cannot perform aseptic filling on the bottle body matched therewith.

[0005] Therefore, the inventors, relying on their many years of experience and practice in related industries, have proposed a sterile quantitative bottle cap and bottle to overcome the defects of the prior art. Summary of the Invention

[0059] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described with reference to the accompanying drawings.

[0060] Implementation Method 1

[0061] like Figures 1 to 9As shown, the present invention provides a sterile quantitative bottle cap, which includes an upper cover body 1 and a lower cover body 2. The upper cover body 1 is a cylindrical structure with a top seal and a bottom opening arranged vertically, and the lower cover body 2 is a cylindrical structure with a top opening and a bottom opening arranged vertically. The upper cover body 1 is arranged on the top of the lower cover body 2, and the bottom of the lower cover body 2 is connected to the top opening of the bottle body 3. A storage part 101 is arranged inside the upper cover body 1. The storage part 101 is a cylindrical structure with an bottom opening arranged in a vertical direction. The top of the storage part 101 is fixedly connected to the top inner wall of the upper cover body 1, and a first sealing part is sealed at the bottom opening of the storage part 101. The top of the first sealing piece 111, the inner wall of the storage part 101 and the top inner wall of the upper cover body 1 are combined to form a storage chamber 102 for accommodating the basic raw material 6, and the storage chamber 102 is sealed by the first sealing piece 111; the internal sealing of the lower cover body 2 is provided with a second sealing piece 201, the upper cover body 1 can be downwardly arranged on the top of the lower cover body 2, the second sealing piece 201 is located below the storage chamber 102, and the top of the second sealing piece 201 is fixedly provided with a second cutting knife 202 that can cut the first sealing piece 111, and the top inner wall of the upper cover body 1 is provided with a first cutting knife 109 that can cut the second sealing piece 201. The upper cover 1 is screwed, and the first sealing piece 111 and the first cutting blade 109 rotate with the upper cover 1 . The first cutting blade 109 cuts the second sealing piece 201 along the edge of the second sealing piece 201 , and the second cutting blade 202 cuts the first sealing piece 111 along the edge of the first sealing piece 111 synchronously.

[0062] The present invention is provided with a storage part 101 in the upper cover body 1, and a first sealing piece 111 is sealed at the bottom opening of the storage part 101. The top of the first sealing piece 111, the inner wall of the storage part 101 and the top inner wall of the upper cover body 1 are combined to form a storage chamber 102. The basic raw material 6 that can be mixed and dissolved with the pure water or basic solution in the bottle body 3 is sealed and accommodated in the storage chamber 102. A second sealing piece 201 for sealing the lower cover body 2 is provided inside the lower cover body 2. The upper cover body 1 can be downwardly arranged on the top of the lower cover body 2. The first sealing piece 111 and the second sealing piece 201 have a double sealing effect on the basic raw material 6, ensuring that the basic raw material 6 is placed in a separate, closed and well-sealed storage space, thereby meeting the requirements of aseptic filling. The first cutting blade 109 is provided on the inner wall of the top of the upper cover body 1, and the second cutting blade 202 is provided on the top of the second sealing piece 201. After the upper cover body moves down to the preset position (that is, the position where the first cutting blade 109 abuts the second sealing piece 201, and the second cutting blade 202 abuts the first sealing piece 111), during the process of screwing the upper cover body 1, the first cutting blade 109 cuts the second sealing piece 201 along the edge of the second sealing piece 201, and the second cutting blade 202 synchronously cuts the first sealing piece 111 along the edge of the first sealing piece 111. During the entire operation, the synchronous cutting of the first sealing piece 111 and the second sealing piece 201 can be completed only by screwing the upper cover body 1, so that the double sealing structure in the bottle cap can be opened at the same time, which is simpler to operate and more convenient to use, ensuring that the basic raw material 6 can fall into the bottle body 3 smoothly, greatly improving the consumer's usage experience.

[0063] The inner diameter of the lower part of the lower cover body 2 in the present invention is the same as the inner diameter of the currently used ordinary bottle cap, which can meet the requirements of connecting with the existing general bottle body. It not only has a wide range of applications, but also can directly perform cap sorting and capping operations on existing beverage filling machines, and can directly complete sterilization treatment in existing sterilization equipment, easily achieving aseptic filling.

[0064] Further, such as Figure 3 、 Figure 6 As shown, both the first sealing sheet 111 and the second sealing sheet 201 are thin sheet structures arranged in a horizontal direction. The edge of the first sealing sheet 111 is sealed to the bottom of the material storage portion 101, and the edge of the second sealing sheet 201 is sealed to the inner wall of the lower cover 2. The connection between the first sealing sheet 111 and the material storage portion 101 can be, but is not limited to, heat sealing or ultrasonic welding; the connection between the second sealing sheet 201 and the lower cover 2 can be, but is not limited to, heat sealing or ultrasonic welding.

[0065] Furthermore, when the upper cover body 1 is in the initial downward state (i.e., the upper cover body 1 is fixedly connected to the lower cover body 2, and the upper cover body 1 does not move downward), a gap is left between the second cutting knife 202 and the bottom surface of the first sealing piece 111, thereby reserving a certain margin for the downward movement of the upper cover body 1, thereby avoiding the second cutting knife 202 from accidentally cutting the first sealing piece 111.

[0066] In an optional embodiment of the present invention, Figures 6 to 9 As shown, a circular cutting portion 203 is provided along the outer edge of the second sealing piece 201. The second sealing piece 201 is connected to the inner wall of the lower cover 2 through the cutting portion 203. The thickness of the cutting portion 203 is less than the thickness of the second sealing piece 201. During the opening process of the second sealing piece 201, the first cutting knife 109 cuts along the cutting portion 203, thereby facilitating the opening of the second sealing piece 201 by the first cutting knife 109.

[0067] Further, such as Figures 6 to 9 As shown, a cutting and opening groove 204 is provided at the top of the cutting portion 203, which is recessed relative to the bottom of the second sealing piece 201. In the initial state where the first cutting knife 109 cuts the second sealing piece 201 and the second cutting knife 202 cuts the first sealing piece 111, the first cutting knife 109 is located in the cutting and opening groove 204 and uses the cutting and opening groove 204 as the starting position for cutting the second sealing piece 201. The first cutting knife 109 cuts the second sealing piece 201 along the cutting portion 203 for one circle and returns to the cutting and opening groove 204. The cutting portion 203 located at the cutting and opening groove 204 remains connected to the inner wall of the lower cover 2. By cutting the opening groove 204, it is convenient to locate the initial cutting position of the cutting portion 203 by the first cutting knife 109. During the opening process of the second sealing piece 201, the first cutting knife 109 will not cut the cutting portion 203 at the cutting opening groove 204, thereby ensuring that the second sealing piece 201 remains connected to the lower cover body 2 when it is flipped down and opened, and preventing the second sealing piece 201 from falling off and falling into the bottle body 3.

[0068] Further, such as Figures 7 to 9As shown, when the first cutting blade 109 is in the starting cutting position for the second sealing piece 201, the first cutting blade 109 and the second cutting blade 202 are arranged opposite to each other along the radial direction of the lower cover body 2, so that the first cutting blade 109 cuts the second sealing piece 201 for a circle and returns to the cutting and opening groove 204. The side of the second sealing piece 201 away from the cutting and opening groove 204 flips downward, and the second cutting blade 202 separates from the first sealing piece 111. The second cutting blade 202 does not complete the cutting of the first sealing piece 111 in a full circle. A connection position is left between the edge of the first sealing piece 111 and the bottom of the storage part 101, so that the first sealing piece 111 remains connected to the storage part 101 when it is flipped down and opened, thereby preventing the first sealing piece 111 from falling off and falling into the bottle body 3.

[0069] Furthermore, a blade is provided on the bottom side edge of the first cutting knife 109 , and the first cutting knife 109 cuts the second sealing piece 201 with the blade of its side edge during rotation, thereby ensuring smooth opening of the second sealing piece 201 .

[0070] Specifically, such as Figure 4 As shown, the cross-section of the material storage part 101 is a "D"-shaped ring structure formed by connecting a straight side and an arc-shaped side. The first cutting knife 109 is located outside the material storage chamber 102 and close to the straight side. When the second cutting knife 202 and the first sealing piece 111 are in a separated state, the position corresponding to the bottom of the material storage part 101 and the straight side is the connection position left between the first sealing piece 111 and the material storage part 101. The first cutting knife 109 uses the position of cutting the opening groove 204 as the cutting starting position, and the second cutting knife 202 uses one end of the straight edge on the storage part 101 as the cutting starting position. When the first cutting knife 109 cuts the second sealing piece 201 for a circle and returns to the cutting and opening groove 204, the second cutting knife 109 cuts the first sealing piece 111 for a circle along the curved edge on the storage part 101 to the other end of the straight edge on the storage part 101. The position where the first sealing piece 111 is relative to the straight edge on the storage part 101 is in a connected state, thereby ensuring that the first sealing piece 111 will not separate from the storage part 101, thereby preventing the first sealing piece 111 from falling off and falling into the bottle body 3.

[0071] In an optional embodiment of the present invention, Figure 9As shown, after the second cutting knife 202 cuts the first sealing piece 111 along the edge of the first sealing piece 111 for a circle, the second sealing piece 201 flips downward to separate the second cutting knife 202 on the second sealing piece 201 from the first sealing piece 111, and the upper cover body 1 moves downward to the end position (i.e., the lowest position), and the connection position between the first sealing piece 111 and the storage part 101 is rotated to the side close to the cutting and opening groove 204, so that the first sealing piece 111 and the second sealing piece 201 flip downward in the same direction, ensuring that the basic raw material 6 in the storage chamber 102 can fall smoothly into the bottle body 3.

[0072] In an optional embodiment of the present invention, Figure 2 、 Figure 3 、 Figure 7 As shown, a circular tear ring 4 is provided between the upper cover body 1 and the lower cover body 2, and the tear ring 4 is arranged along the circumference of the upper cover body 1 and the lower cover body 2. A circular step with an increased diameter is provided on the middle outer wall of the lower cover body 2 along the circumference of the lower cover body 2. The top of the tear ring 4 is connected to the bottom edge of the upper cover body 1, and the bottom of the tear ring 4 is connected to the top of the circular step. The upper cover body 1 and the lower cover body 2 are fixed by the tear ring 4 to ensure that the upper cover body 1 and the lower cover body 2 are firmly connected before the bottle cap is opened.

[0073] Further, such as Figure 2 、 Figure 3 As shown, a tear ring opening 401 is left on the tear ring 4 to facilitate tearing the tear ring 4 so that the upper cover body 1 can be smoothly screwed down.

[0074] In an optional embodiment of the present invention, Figure 3 、 Figure 5 、 Figure 6 As shown, a plurality of first non-return grooves 108 are provided on the inner wall of the upper cover body 1 along the circumference of the upper cover body 1, a plurality of second non-return grooves 402 corresponding to the vertical positions of the first non-return grooves 108 are provided on the inner wall of the tear ring 4 along the circumference of the tear ring 4, and a plurality of non-return bosses 206 that can respectively cooperate with the first non-return grooves 108 and the second non-return grooves 402 are provided on the outer wall of the lower cover body 2 along the circumference of the lower cover body 2. When the upper cover body 1 is connected to the lower cover body 2 and the tear ring 4 is not torn off, the second non-return grooves 402 on the tear ring 4 cooperate and engage with the non-return boss 206 on the lower cover body 2; when the upper cover body 1 is connected to the lower cover body 2 and the tear ring 4 has been torn off, the upper cover body 1 moves downward and the first non-return grooves 108 on the upper cover body 1 cooperate and engage with the non-return boss 206 on the lower cover body 2. During the entire process of opening the first sealing piece 111 and the second sealing piece 201, the first non-return grooves 108 and the second non-return grooves 402 cooperate and engage with the non-return boss 206 respectively to ensure that the upper cover body 1 cannot be reversely twisted, thereby ensuring the safety of the basic raw material 6.

[0075] Specifically, such as Figure 3 、 Figure 6 As shown, the cross-sections of each first non-return groove 108, each second non-return groove 402 and each non-return boss 206 are all serrated and inclined toward the screwing direction of the upper cover body 1, thereby ensuring that the upper cover body 1 can be screwed in one direction.

[0076] In an optional embodiment of the present invention, Figure 3 、 Figures 7 to 9 As shown, a push rod 110 is vertically arranged inside the upper cover body 1, and the push rod 110 is connected to the first cutting knife 109. The bottom end of the push rod 110 extends downward to above the second sealing piece 201. The vertical length of the push rod 110 located between the first sealing piece 111 and the second sealing piece 201 is smaller than the vertical length of the first cutting knife 109 located between the first sealing piece 111 and the second sealing piece 201. When the upper cover body 1 moves downward, after the first cutting knife 109 cuts the second sealing piece 201, the bottom end of the push rod 110 can abut against the second sealing piece 201, thereby pushing the second sealing piece 201 open to ensure that the basic raw material in the storage chamber 102 can smoothly fall into the bottle body 3.

[0077] In an optional embodiment of the present invention, Figure 3 As shown, a circular sealing boss 103 is provided on the top inner wall of the upper cover body 1 along the circumference of the upper cover body 1, and the sealing boss 103 is arranged in a ring on the outer side of the storage part 101. The bottom of the sealing boss 103 is connected to an extension rod 1031 extending downward, and the first cutting knife 109 is connected to the extension rod 1031, and the first cutting knife 109 is located on the inner side of the sealing boss 103, and the root outer wall of the first cutting knife 109 is connected to the inner wall of the sealing boss 103, and the end of the first cutting knife 109 extends downward to above the edge of the second sealing piece 201. When the upper cover body 1 moves down to the end position, the outer wall of the sealing boss 103 is sealed with the upper inner wall of the lower cover body 2, thereby improving the sealing effect between the upper cover body 1 and the lower cover body 2.

[0078] Furthermore, the sealing boss 103 and the upper cover 1 may be, but are not limited to, integrally formed.

[0079] In an optional embodiment of the present invention, Figure 3 、 Figures 7 to 9As shown, at least one first sealing ring 106 and at least one second sealing ring 107 are provided on the top inner wall of the upper cover body 1 along the circumference of the upper cover body 1. The setting position of the first sealing ring 106 is opposite to the top plane position of the lower cover body 2, and the setting position of the second sealing ring 107 is opposite to the upper outer wall position of the lower cover body 2. When the upper cover body 1 moves down to the terminal position, the first sealing ring 106 is pressed between the top inner wall of the upper cover body 1 and the top edge of the lower cover body 2, and the second sealing ring 107 is pressed between the top inner wall of the upper cover body 1 and the upper outer wall of the lower cover body 2. When the upper cover body 1 moves down to the end position, the sealing boss 103 is sealedly connected to the inner wall of the lower cover body 2, the first sealing ring 106 is sealedly connected to the top edge of the lower cover body 2, and the second sealing ring 107 is sealedly connected to the upper outer wall of the lower cover body 2, thereby forming an inner seal, a top seal and an outer seal for the storage chamber 102, improving the sealing effect. After the basic raw material 6 in the storage chamber 102 falls into the bottle body 3, it can still ensure good sealing between the upper cover body 1 and the lower cover body 2, thereby meeting the requirements of aseptic filling.

[0080] Furthermore, the first sealing ring 106 and the upper cover body 1 may be, but are not limited to, integrally formed; the second sealing ring 107 and the upper cover body 1 may be, but are not limited to, integrally formed.

[0081] In an optional embodiment of the present invention, Figure 5 、 Figure 6 As shown, an anti-theft ring 5 is provided under the lower cover body 2, and the top of the anti-theft ring 5 is connected to the bottom edge of the lower cover body 2 through multiple connection points. The anti-theft ring 5 is sleeved on the outside of the top opening of the bottle body 3, and the lower cover body 2 is fixed by the anti-theft ring 5 to prevent the lower cover body 2 from being separated from the bottle body 3 when the sterile quantitative bottle cap is not opened, thereby improving the stability of the connection between the sterile quantitative bottle cap and the bottle body 3.

[0082] In an optional embodiment of the present invention, the upper cover body 1 and the lower cover body 2 are connected via a threaded structure, and the lower cover body 2 and the bottle body 3 are connected via a threaded structure.

[0083] Specifically, such as Figures 3 to 9 As shown, a first internal thread 105 is provided on the lower inner wall of the upper cover body 1, and a first external thread 205 is provided on the upper outer wall of the lower cover body 2. The lower inner wall of the upper cover body 1 and the upper outer wall of the lower cover body 2 are connected by the first internal thread 105 and the first external thread 205; a second internal thread 208 is provided on the lower inner wall of the lower cover body 2, and a second external thread 301 is provided on the outer wall of the top opening of the bottle body 3. The lower inner wall of the lower cover body 2 and the outer wall of the top opening of the bottle body 3 are connected by the second internal thread 208 and the second external thread 301.

[0084] In another optional embodiment of the present invention, the upper cover body 1 and the lower cover body 2 can also be connected by a snap-fit ​​structure to ensure that the upper cover body 1 can move downward relative to the lower cover body 2 and the upper cover body 1 and the lower cover body 2 can rotate relative to each other.

[0085] Specifically, the snap-fit ​​structure includes a plurality of first snap rings with serrated cross-sections arranged on the inner wall of the upper cover body 1 and a plurality of second snap rings with serrated cross-sections arranged on the outer wall of the lower cover body 2. The upper cover body 1 and the lower cover body 2 are snap-fitted together by the cooperation of each first snap ring and each second snap ring. After tearing off the tear ring 4, the upper cover body 1 can be controlled to move downward by pressing downward.

[0086] In an optional embodiment of the present invention, Figure 1 、 Figure 2 As shown, a first anti-slip pattern 104 is provided on the outer wall of the upper cover body 1. The first anti-slip pattern 104 is a plurality of first convex ribs provided on the outer wall of the upper cover body 1 along the vertical direction. The first convex ribs are evenly arranged on the outer wall of the upper cover body 1 along the circumference of the upper cover body 1. The friction force of the outer wall of the upper cover body 1 is increased by the first anti-slip pattern 104, which facilitates the screwing of the upper cover body 1 and the opening of the first sealing piece 111 and the second sealing piece 201.

[0087] Further, such as Figures 1 to 3 As shown, each first rib is in an arc shape that bulges away from the upper cover body 1 , which further increases the friction force of the outer wall of the upper cover body 1 compared with the existing anti-slip grooves, making it easier to screw the upper cover body 1 .

[0088] In an optional embodiment of the present invention, Figure 1 、 Figure 5 As shown, a second anti-slip pattern 207 is provided on the outer wall of the lower cover body 2. The second anti-slip pattern 207 is a plurality of second convex ribs provided on the outer wall of the lower cover body 2 along the vertical direction. The second convex ribs are evenly arranged on the outer wall of the lower cover body 2 along the circumference of the lower cover body 2. The friction force of the outer wall of the lower cover body 2 is increased by the second anti-slip pattern 207, which facilitates the screwing of the lower cover body 2 and facilitates the opening of the puncture bottle cap of the present invention.

[0089] After the bottle 3 is filled with pure water or basic solution, the upper cover body 1 is inverted, and the basic raw material 6 is filled from the bottom opening of the storage part 101 into the storage chamber 102 on the filling and storage equipment. After the filling of the basic raw material 6 is completed, the first sealing piece 111 is sealed at the bottom opening of the storage part 101 by heat sealing or ultrasonic welding, so that the storage chamber 102 forms a closed space. Then, the upper cover body 1 and the lower cover body 2 are connected by a threaded structure, and a certain margin is left between the top of the lower cover body 2 and the top inner wall of the upper cover body 1 (that is, after the upper cover body 1 is assembled with the lower cover body 2, the upper cover body 1 can still move downward a distance), completing the assembly of the upper cover body 1 and the lower cover body 2 and the sealing of the bottle body 3. When drinking, first tear off the tear ring 4 between the upper cover body 1 and the lower cover body 2, hold the first anti-slip groove 104 on the outer wall of the upper cover body 1 and screw the upper cover body 1 in the clockwise direction, and the upper cover body 1 moves downward along the threaded structure. When the first sealing piece 111 contacts the second cutting knife 202, the second cutting knife 202 cuts the first sealing piece 111 along the edge of the first sealing piece 111. At the same time, the first cutting knife 109 falls into the cutting and opening groove 204 and cuts the second sealing piece 201 along the cutting portion 203 from the cutting and opening groove 204 as the starting position. When the first cutting knife 109 cuts the second sealing piece 201 once and returns to the cutting and opening groove 204, the first cutting knife 109 is in a suspended state in the cutting and opening groove 204, thereby ensuring that the second sealing piece 201 will not be completely cut off. Under the action of the force, the side of the second sealing piece 201 away from the cutting and opening groove 204 flips downward by a certain angle, so that the second cutting knife 202 connected to the second sealing piece 201 moves downward by an end distance and separates from the first sealing piece 111. Since the first cutting knife 109 and the second cutting knife 202 are designed to be diagonal (that is, the first cutting knife 109 and the second cutting knife 202 are arranged opposite to each other along the radial direction of the lower cover 2), the second cutting knife 109 cuts along the arc edge on the material storage part 101, leaving the straight edge on the material storage part 101 always connected to the first sealing piece 109, and the first cutting knife 109 and the second cutting knife 202 perform cutting synchronously, thereby ensuring that the first sealing piece 111 will not be completely cut off, and the connection position between the first sealing piece 111 and the material storage part 101 is still retained, thereby preventing the first sealing piece 111 from falling off. At this time, the basic raw materials in the storage chamber 102 fall into the bottle body 3 under the action of gravity, completing the entire opening process of the aseptic quantitative bottle cap.

[0090] When the opening operation of the first sealing piece 111 and the second sealing piece 201 is completed, the upper cover body 1 has moved down to the end position, and the inner side sealing, top sealing and outer side sealing of the upper cover body 1 and the lower cover body 2 are achieved through the sealing boss 103, the first sealing ring 106 and the second sealing ring 107, ensuring that the bottle cap as a whole can still maintain a good secondary sealing effect after the basic raw material 6 is added.

[0091] The characteristics and advantages of the aseptic quantitative bottle cap of the present invention are:

[0092] 1. The aseptic quantitative bottle cap is provided with a first sealing piece 111 and a second sealing piece 201. The first sealing piece 111 and the second sealing piece 201 can achieve a double sealing effect on the basic raw material 6, ensuring that the basic raw material 6 is always placed in a separate, sealed and well-sealed storage space, thereby meeting the requirements of aseptic filling. The second cutting knife 202 and the first cutting knife 109 can synchronously cut the first sealing piece 111 and the second sealing piece 201, quickly completing the opening of the double sealing structure, which is convenient and quick, ensuring that the basic raw material 6 can fall smoothly into the bottle body 3, and greatly improving the consumer's usage experience.

[0093] 2. The inner diameter of the lower part of the lower cover body 2 in the aseptic quantitative bottle cap is the same as the inner diameter of the existing ordinary bottle cap, which can meet the requirements of connecting with the existing general bottle body. It not only has a wide range of applications, but also can be directly used in the existing beverage filling machine to perform cap sorting and capping work without the need to modify the equipment. Especially for aseptic filling products, the lower cover body 2 can be directly sterilized in the existing sterilization equipment without worrying about incomplete sterilization or residual sterilization solvents, and aseptic filling can be easily achieved.

[0094] 201 , the second sealing piece 201 is opened by the first cutting blade 109, and the second sealing piece 201 is opened by the first cutting blade 109.

[0095] 4. In the sterile quantitative bottle cap, a plurality of first non-return grooves 108 are provided on the inner wall of the upper cover body 1, a plurality of second non-return grooves 402 are provided on the inner wall of the tear ring 4, and a plurality of non-return bosses 206 are provided on the outer wall of the lower cover body 2. The first non-return grooves 108 and the second non-return grooves 402 can be respectively engaged with the non-return bosses 206 to ensure that the upper cover body 1 cannot be rotated in the reverse direction, thereby ensuring the safety of the basic raw material 6.

[0096] Implementation Method 2

[0097] like Figures 7 to 9 As shown, the present invention provides a bottle, which includes a bottle body 3 and the above-mentioned sterile quantitative bottle cap, and the sterile quantitative bottle cap is arranged on the top opening of the bottle body 3.

[0098] Further, such as Figures 7 to 9 As shown, a second internal thread 208 is provided on the inner wall of the bottom of the sterile quantitative bottle cap, and a second external thread 301 is provided on the outer wall of the top opening of the bottle body 3. The sterile quantitative bottle cap and the bottle body 3 are connected through the second internal thread 208 and the second external thread 301.

[0099] The characteristics and advantages of the bottle of the present invention are:

[0100] The bottle has a simple structure, and the bottle body 3 and the sterile quantitative bottle cap can be matched and connected. The sterile quantitative bottle cap can provide a separate and stable sealed space for the basic raw material 6, and has good sealing performance. The sterile quantitative bottle cap and the bottle body 3 are sealed and connected, which can realize the aseptic filling of the basic solution inside the bottle body 3, so that the bottle body 3 and the puncture bottle cap can also be used in the sterile market, and have a wider range of applications.
