[0011] The solid-liquid separation bottle cap described in the utility model is as follows Figure 1 and Figure 2 As shown, it includes a cover body 1, which can be screwed onto the bottle mouth of a volumetric flask. A vertically arranged straw 2 is fixedly connected inside the cover body 1. The lower part of the straw 2 is a piercing bevel 3, and the upper part of the straw 2 extends upward from the cover body 1. The straw 2 can rise and fall vertically synchronously with the cover body 1. While serving as a suction channel for the beverage, it can also serve as a piercer to mix the independently packaged solvent with the liquid phase.

[0012] In order to achieve the sealing effect on the straw 2, a buckle cover 4 that can be rotatably opened and closed is installed on the cover body 1. When the buckle cover 4 is buckled on the cover body 1, the upper end of the straw 2 can be blocked. The sealed straw 2 can reduce the deterioration caused by microorganisms entering the bottle.

[0013] In order to realize the independent storage of the solvent and the liquid phase, a silo 5 is further provided in the cover body 1 at the lower end of the straw 2, and a pressing plate 6 is provided at the upper end of the silo 5, wherein the silo 5 is located in the bottle mouth, and the pressing plate 6 is located on the upper side of the bottle mouth, so as to realize the positioning and installation of the silo 5 at the bottle mouth. Aluminum foil sheets 7 are provided in the pressing plate 6 and at the bottom of the silo 5, and when the straw 2 moves vertically downward, the aluminum foil sheets 7 at the upper and lower ends can be pierced, so that the solvent in the silo 5 is mixed with the liquid phase.

[0014] A pressing ring 8 is also provided on the upper side of the pressing plate 6. The pressing ring 8 can position and press the pressing plate 6 on the silo 5 onto the bottle mouth. The pressing ring 8 is an independent part. It only has a matching relationship with the cover body 1 and the bottle mouth, but no connection relationship. In order to realize the installation of the cover body 1 on the bottle mouth, and to ensure that the piercing bevel 3 of the straw 2 will not pierce the aluminum foil 7 after installation, a detachable limiting ring 9 is provided on the inner periphery of the cover body 1. The limiting ring 9 is fixedly arranged on the inner periphery of the cover body 1, and a notch that is easily damaged is opened at the connection position. When the limiting ring 9 is fixed on the cover body 1, it is located on the upper side of the pressing ring 8. The pressing plate 6 of the silo 5 is positioned and pressed together by the pressing ring 8. At this time, the piercing bevel 3 is located on the upper side of the aluminum foil 7 in the pressing plate 6, and will not damage the aluminum foil 7. The solvent in the silo 5 will not mix with the liquid phase.

[0015] An internal thread matching the bottle mouth is provided on the inner circumference of the cover body 1. When the cover body 1 is rotated to move downward relative to the bottle mouth, the limit ring 9 is forced to separate from the cover body 1, and the straw 2 moves downward with the cover body 1 and can penetrate the pressure plate 6 and the aluminum foil 7 at the bottom of the silo 5, so that the solvent and the liquid phase in the silo 5 can be mixed.

[0016] The arrangement of the above structure facilitates installation on the bottle mouth. The outer periphery of the bottle mouth is provided with an external thread that matches with the cover body 1 to achieve a screw connection between them. The built-in installation of the silo 5 and the bottle cap structure is also easy to achieve. First, the silo 5 filled with solvent is placed into the bottle mouth, and the pressure plate 6 on the top of the silo 5 is located on the upper side of the bottle mouth to achieve positioning installation. Subsequently, a pressure ring 8 is installed on the upper part of the pressure plate 6, and the cover body 1 is screwed onto the bottle mouth. After the limiting ring 9 contacts the pressure ring 8, the rotation of the cover body 1 is stopped. At this time, the punctured bevel 3 is located on the upper side of the aluminum foil 7, and the solvent will not mix with the liquid phase in the bottle, thereby completing the limiting installation of the cover body 1.

[0017] If you want to drink the beverage, press down hard and rotate the cover 1 to separate the limiting ring 9 from the cover 1, and rotate the cover 1 downward. Figure 3 As shown, the internal straw 2 moves downward synchronously and pierces the aluminum foil sheets 7 at the upper and lower ends of the silo 5, and the bottle body is shaken to mix the solvent in the silo 5 with the liquid phase in the bottle. Then, the buckle cover 4 is opened, and the mixed beverage can flow out from the position of the straw 2 for drinking. After pouring out part of the beverage, the buckle cover 4 can be turned to close to prevent dirt or microorganisms from entering the bottle through the straw 2 and causing the beverage to deteriorate.

[0018] One end of the buckle cover 4 is hingedly mounted on the cover body 1 through a pin 10, and a positioning plug 11 is provided at the other end of the buckle cover 4. A slot that is interference-fitted with the positioning plug 11 is provided on the cover body 1, wherein the positioning plug 11 can be made of elastic material, and the buckle cover 4 is rotated and fastened on the cover body 1 through interference-fit insertion. In order to seal the end of the straw 2 after the buckle cover 4 is rotated and fastened, a sealing ring 12 that matches the end of the straw 2 is also provided on the buckle cover 4.

[0019] After the straw 2 pierces the aluminum foil 7, in order to prevent the pierced and split aluminum foil 7 fragments from being eaten by consumers through the straw 2, a filter 13 is provided inside the upper end of the straw 2, and the filter 13 can prevent the aluminum foil fragments from flowing out through the straw 2. When the straw 2 penetrates and pierces the aluminum foil 7 at the bottom of the pressing plate 6 and the silo 5, the filter 13 is located at the upper part of the pressing plate 6. After the straw 2 pierces the aluminum foil 7 at the upper and lower ends of the silo 5, the filter 13 will not enter the silo 5, and will not interfere with the internal solvent, which can effectively reduce unnecessary resistance and friction, and ensure the completion of the normal piercing operation.

[0020] In order to ensure that the straw 2 can push out all the solvent in the silo 5 to complete the mixing with the liquid phase while piercing the aluminum foil 7 at the upper and lower ends, the outer diameter of the straw 2 is matched with the inner diameter of the silo 5. In order to prevent the silo 5 from swinging or tilting during the rotation of the cover body 1, which will affect the piercing of the aluminum foil 7 by the straw 2, the outer periphery of the pressing plate 6 is matched with the inner periphery of the cover body 1, wherein the aluminum foil 7 is located on the inner periphery of the pressing plate 6, and the center of the aluminum foil 7 will be pierced when the straw 2 moves downward.

[0021] In order to ensure that the straw 2 pierces the aluminum foil sheets 7 at the upper and lower ends of the silo 5 before subsequent drinking, it is avoided that only the aluminum foil sheet 7 at the upper end is pierced and only the solvent is drunk, such as Figure 4 As shown, a puncture unlocking and opening mechanism is installed between the cover body 1 and the buckle cover 4, and the puncture unlocking and opening mechanism includes a locking rod 14 fixed on the buckle cover 4, and the locking rod 14 can move with the buckle cover 4. A through hole is provided on the cover body 1 for the locking rod 14 to pass through, and a locking head 15 is provided at the end of the locking rod 14 located in the cover body 1, and the locking head 15 always has a tendency to hook the inner end surface of the cover body 1 to prevent the buckle cover 4 from rotating and opening.

[0022] The pressing ring 8 is provided with an unlocking groove 16, and the locking head 15 is provided with an inclined surface 17 that matches the unlocking groove 16. After the cover body 1 is rotated downward to allow the straw 2 to pierce the aluminum foil sheet 7 at the bottom of the pressing plate 6 and the silo 5, Figure 5 As shown, the pressing ring 8 moves upward relative to the cover body 1 and pushes the locking head 15 completely into the through hole through the unlocking ring groove 16. After the locking head 15 is no longer limited, the buckle cover 4 can be rotated to open.

[0023] With the above structure, when the straw 2 does not puncture the aluminum foil sheets 7 at the upper and lower ends, the pressure ring 8 will not move up to push the locking head 15 to move, and the buckle cover 4 will not be easily opened under the limiting effect of the locking head 15, which is equivalent to reminding consumers that the solvent has not yet mixed with the liquid phase. Only when the aluminum foil sheets 7 at the upper and lower ends are completely punctured and the solvent and the liquid phase are mixed, the pressure ring 8 moves up to the specified position relative to the cover body 1, and the unlocking ring groove 16 on the pressure ring 8 pushes the locking head 15 to move completely into the through hole, and then the buckle cover 4 can be opened relative to the cover body 1, so that the mixed beverage can be consumed.

[0024] The solid-liquid separation bottle cap of the present invention has a simple overall manufacturing process, is easy to place and use, and can make the contents such as solvents have a longer shelf life. The product of this design can be large or small, and can be used for beverages, and can also be used for the storage of materials that are not easy to mix and need to be stored for a long time. After the contents such as solvents are placed in this structure, if it is not opened, the shelf life can be as long as 36 months, or even longer, which fully meets the manufacturer's requirements for product quality and the health requirements of consumers.

[0025] The solvent in the silo 5 can be a dry or wet content, and the content is separated from the solution in the bottle. For example, if the content in the bottle is water and the silo 5 is a nutrient-rich solvent, the water in the bottle will not change or deteriorate due to the nutrients in the silo.

[0026] The upper end of the silo 5 can be connected with aluminum foil or other materials by ultrasonic or heat sealing, and then sealed after the set material is installed, so that it cannot contact with the air, and microorganisms in the air cannot enter, so as to achieve the purpose of long-term preservation. After the dry material solvent is loaded into the silo 5, the microorganisms in the material in the silo 5 are inactivated by disinfection. At the same time, due to the effect of tight sealing, any microorganisms or air in the space cannot enter, so that the contents of the silo 5 can be kept for a long time without deterioration. The disinfection method can be cobalt 60 or single number blast disinfection, or pasteurization or flash sterilization at a temperature lower than the silo material temperature but higher than or equal to the inactivation temperature.

[0027] The bottom of the silo 5 can be an ultra-thin part during injection molding, which can be easily pierced and damaged by the straw 2, so that the liquid in the volumetric flask can be mixed with the material in the silo 5 to achieve the purpose of use. After mixing, the buckle cover 4 is opened, and the solid-liquid mixture in the bottle can flow out through the straw 2. If the flow needs to be stopped, the buckle cover 4 can be closed. After closing the buckle cover 4, the buckle cover 4 is tightly combined with the straw 2, and the liquid in the bottle cannot flow out.

[0028] The structure of the utility model can be used for all food-grade polypropylene and polyethylene materials that are resistant to high temperatures. When using this patent to contain corrosive substances, attention should be paid to whether the placed object may corrode and damage the entire bottle cap (plastic part). The utility model can also use food-grade polyethylene, polypropylene or other materials that meet food requirements and be applied to mineral water, beverages, alcoholic beverages, etc.

[0029] The structure also has the following features: 1. The structure is user-friendly and easily accepted by consumers. 2. It has a wide range of uses, and can be used in liquid and powder forms. 3. The manufacturing process is simple, and it can be combined with a bottle made of any material without injection molding. 4. It extends the shelf life of beverages, mineral water, etc. The solid-liquid separation and the inactivation of the solids after strict sealing prevent the space microorganisms from entering the liquid phase, and the contents of the silo cannot be exposed to the air, thereby extending the shelf life.

[0030] The shelf life of beverages filled with beverages using the bottle cap of this structure is as follows (storage temperature is minus to 20 degrees):

[0031] The silo contains protein-rich beverage solids, and the bottle body contains liquid (drinking water, ethanol and other food-grade materials). When not opened, the shelf life can reach 36 months. After opening, the liquid is mixed with the solid in the silo, and the shelf life is good for 24 hours at room temperature. After the liquid and solid are mixed, the cover needs to be pressed tightly, and it can be stored for a long time in a frozen state. When liquid nutrients are placed in the silo, it should be noted that the aluminum foil film or other materials should be tightly combined with the silo to ensure that the liquid nutrients inside do not overflow (there are many reasons for overflow, such as overheating, overcooling or unstable temperature in the storage site, which can cause cracking). Therefore, beverages using the bottle cap of this structure should be stored at an appropriate temperature like conventional food and beverages.

[0032] The technical solution of the present invention is not limited to the scope of the embodiments described in the present invention. The technical contents not described in detail in the present invention are all known technologies.
