Description

Technical Field

[0001] The invention belongs to the technical field of beverage packaging, and in particular relates to a ready-to-drink beverage bottle cap, a beverage bottle, and a filling method for the ready-to-drink beverage bottle cap. Background Art

[0002] Although ready-to-drink (RTD) honey water beverages have the convenience of drinking as soon as the bottle is opened, they are limited by the characteristics of pre-mixing and industrial production, making it difficult to strike a balance between naturalness and stability. The high-temperature sterilization process will destroy the active enzymes and volatile aroma components in honey, resulting in a faded flavor and loss of nutrients; the glucose in honey is prone to crystallization and precipitation during storage, causing stratification or precipitation, and requires reliance on additives to maintain uniformity, which may affect the natural taste; and due to differences in raw materials, the flavor needs to be stabilized through compounding or flavoring, losing the uniqueness of single honey. At the same time, preservatives may be added to extend the shelf life, which conflicts with consumers' expectations of "natural and additive-free".

[0003] In contrast, ready-to-drink honey water beverages use separate packaging, namely the storage bottle cap and the bottle body, to avoid the loss of active ingredients and flavor deterioration caused by premature mixing of honey and water. It can retain the natural essence of honey to the greatest extent, avoid high-temperature sterilization, and better preserve the original flavor, color and precious active ingredients (such as enzymes) of honey. However, the existing single-layer structure design of the instant beverage bottle cap lacks thermal insulation ability and cannot isolate the influence of external temperature. In the low temperature environment of winter, the independently encapsulated honey or concentrated liquid in the bottle cap is prone to sudden increase in viscosity or even solidification due to freezing, which not only makes it difficult to mix smoothly with the base liquid, but also may damage the sealing structure due to volume expansion. At the same time, to ensure the sealing of the storage bottle cap, the bottom of the dissolving cavity adopts a thickened sealing film (such as composite aluminum foil) and undergoes high-pressure heat sealing treatment, so that the sealing layer fits tightly and has high puncture resistance. However, the bottom of the existing piercing component is mostly cylindrical in design, and its end is a flat surface or a small arc surface, which has a large contact area with the sealing film. During puncture, the pressure is dispersed over a wide area, and it is impossible to form a concentrated piercing force, making it difficult to effectively pierce the sealing layer, resulting in obstruction of the ingredient operation. In addition, to ensure the sealing, the existing storage bottle cap often adopts a multi-component nested design and the superposition of multi-dimensional sealing structures, which increases the number of components in the overall structure and complicates the structure, thereby causing the problem of complex filling process. Summary of the Invention

[0004] In order to overcome the shortcomings of the above-mentioned prior art, the purpose of the present invention is to provide a ready-to-drink beverage bottle cap, a beverage bottle and a filling method for the ready-to-drink beverage bottle cap, which solves the problem that the bottom of the dissolving cavity of the existing ready-to-drink beverage bottle cap is not easily punctured during the ingredient mixing operation. At the same time, the overall structure is simple, which simplifies the filling process.

[0005] The present invention is achieved through the following technical solutions:

[0006] A ready-to-drink beverage bottle cap comprises a screw-on upper cap and a lower cap with a closed top, a pull ring being connected between the screw-on upper cap and the lower cap, and a poke cone being movably provided in the lower cap;

[0007] The lower cover comprises a lower cover body connected to the mouth of the beverage bottle by a threaded connection, and a cavity body penetrating the lower cover body and integrally connected to the lower cover body, with a closed bottom; the top of the cavity body is integrally connected to a connector for connecting to the screw upper cover, and a limiting ring is provided on the inner wall of the connector body at the connection point between the connector and the cavity body; the outer side of the lower cover body is provided with a lower shell body integrally formed with the lower end of the connector body;

[0008] The poking cone includes a cylindrical barrel and a conical puncture structure connected to a cylindrical bottom. A plurality of liquid outlet holes are provided on the cylindrical barrel and at the outer periphery connected to the conical puncture structure. The cross section of the conical puncture structure is cross-shaped. An annular flange is provided on the upper part of the cylindrical barrel, and the annular flange contacts the inner wall of the connector. An extrusion ring is provided at the top inner end of the spiral cover, and the extrusion ring is tightly attached to the annular flange. The rotation of the spiral cover drives the extrusion ring to squeeze the annular flange to slide, thereby driving the poking cone to slide in the connector. The conical puncture structure of the poking cone punctures the bottom of the cavity and the ingredients flow out.

[0009] Furthermore, the distance that the annular flange slides to the limiting ring in the connector must ensure that the piercing cone punctures the bottom opening of the cavity to the maximum.

[0010] Furthermore, the diameter of the lower shell is the same as the diameter of the beverage bottle connected to the instant beverage bottle cap.

[0011] Furthermore, the diameter of the connector in the lower cover is larger than the diameter of the cavity.

[0012] Furthermore, the bottom of the cavity is an inclined end surface.

[0013] Furthermore, the outer periphery of the connector is provided with an external thread segment which is screwed together with the spiral upper cover.

[0014] Furthermore, the outer wall of the spiral cover is provided with anti-slip grooves, an inner ring is provided at the inner end of the top of the spiral cover and the inner side of the extrusion ring, and reinforcing ribs are provided between the extrusion ring and the inner ring.

[0015] Furthermore, a thread is provided on the inner wall of the lower cover.

[0016] A beverage bottle comprising the instant beverage bottle cap has an external bottle mouth thread at the top of the bottle mouth that is screwed together with the thread of the lower cover body, a reinforcement ring is provided at the middle and lower part of the bottle mouth, and the bottle body of the beverage bottle is connected to the lower cover body of the storage bottle cap through the external bottle mouth thread.

[0017] A filling method for the instant beverage bottle cap comprises the following steps:

[0018] Step 1: Honey pretreatment: Preheat the honey to 40-50℃ and place it in a vacuum environment of -0.08 to -0.09MPa for 15-30 minutes to allow bubbles to gather, burst and be discharged. Then filter it through an 80-120 mesh filter to remove impurities and pasteurize it at 55-60℃. Then quickly cool it to below 25℃ and seal it in a sterile environment.

[0019] Step 2: The ready-to-drink beverage bottle caps are passed through an automated cleaning line, sprayed with peracetic acid for disinfection, and then dried with hot air. After sterilization, the total number of microorganisms is ≤100 CFU / g. The sterilized ready-to-drink beverage bottle caps are immediately transferred to a clean workshop;

[0020] Step 3: Fix the lower cover of the beverage bottle cap with an assembly line fixture in a clean workshop so that the filling port of the cavity is facing upward, ensure that it is aligned with the center of the cavity during filling, and place the cone in the connector and the dissolving cavity;

[0021] Step 4: Deduct the volume of the cavity occupied by the cone from the volume of the cavity, preset the filling volume, and use a screw pump filling machine to fill the honey;

[0022] Step 5: Use a servo capping machine to tighten the screw cap and the pull ring onto the connector to obtain the instant beverage bottle cap after filling with honey;

[0023] Step 6: After filling the honey, the instant beverage bottle caps are subjected to an inversion test including vibration, a positive and negative pressure test, and a liquid barrier test, and the instant beverage bottle caps that meet the requirements of 0% leakage rate, no bubbles under a positive pressure of 0.03MPa for 30 seconds, and no air infiltration under a negative pressure of -0.05MPa are selected;

[0024] Step 7: Use a capping machine to screw the screened instant beverage bottle cap onto the bottle filled with water through the lower cover body. The weight ratio of honey to water in the honey storage cavity is 1:10, and the filling process is completed.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] The present invention adopts a conical puncture structure design, so that the puncturing cone can concentrate its force on a smaller area when the spiral upper cover rotates, forming a concentrated puncturing force, effectively and smoothly piercing the sealing layer at the bottom of the cavity, ensuring the smooth flow of ingredients, and avoiding the problem of obstruction of ingredient operation caused by the difficulty in piercing the sealing layer; at the same time, the double-layer insulation structure formed by the lower cover and the cavity can effectively isolate the influence of the external temperature on the honey or concentrated liquid encapsulated in the cavity, avoiding the honey or concentrated liquid from freezing, thickening and solidifying in the low temperature environment in winter, and ensuring smooth mixing with the base liquid.

[0027] The bottom of the cavity of the present invention is an inclined end surface, which guides the force of the poking cone to a localized area. Compared with the uniform force of a horizontal end surface, it is easier to break through the tensile strength of the sealing membrane and achieve rapid puncture. At the same time, the inclined end surface allows the tip of the poking cone to first contact the sealing membrane with "line contact" or "small area point contact". As the poking cone continues to apply pressure, the contact point gradually expands to the periphery. At the same time, the inclined end surface can form a natural diversion slope after puncture. Combined with the design of the poking cone's liquid outlet, it can reduce honey residue at the bottom of the dissolving cavity and further improve the thoroughness of the content mixing.

[0028] The present invention realizes the sealed preservation of honey through the cooperation between the spiral upper cover, the pull ring and the lower cover. It has a simple structure and strong sealing performance. It uses a closed cavity to store honey. There is no need to accurately avoid the raised structure during filling. The conventional caliber filling nozzle can be used to directly inject honey in position, eliminating the need for multi-axis displacement debugging. At the same time, since there is no need for secondary assembly of split components, after filling, the sealing can be completed only by the threaded cooperation of the spiral upper cover and the lower cover, reducing the redundant process of "pre-fixing components-filling-removing fixation-secondary sealing". There is no need to adjust multiple sets of parameters for complex structures during production change, which significantly shortens the production cycle, makes the filling process easier to realize automated assembly line operation, and reduces equipment investment and operation difficulty.

DETAILED DESCRIPTION

[0036] The present invention will be further described in detail below with reference to specific embodiments, which are intended to explain the present invention rather than to limit it.

[0037] refer to Figure 1 As shown, a ready-to-drink beverage bottle cap includes a screw cap 1 and a lower cap 2 with a closed top, a pull ring 3 connected between the screw cap 1 and the lower cap 2, and the pull ring 3 is connected to the screw cap 1 and the lower cap 2 through a breakable connection point, and a poke cone 4 is movably provided in the lower cap 2;

[0038] refer to Figure 2 As shown, the lower cover 2 includes a lower cover body 24 that is connected to the mouth of the beverage bottle by a thread, and a cavity body 23 that passes through the lower cover body 24 and is integrally connected to the lower cover body 24 and has a closed bottom. The cavity body is used to store honey; the top of the cavity body 23 is integrally connected to a connector 22 for connecting to the screw-on cover 1, and the outer periphery of the connector 22 is provided with an external thread section that screws with the screw-on cover 1. The diameter of the connector 22 is larger than the diameter of the cavity body 23. At the same time, a limiting ring 25 is provided on the inner wall of the connector 22 at the connection point between the connector 22 and the cavity body 23. The double cooperation of the two methods can prevent the piercing cone from falling into the bottle body, thereby increasing the reliability of the device; the outer side of the lower cover body 24 is provided with a lower shell 21 that is integrally formed with the lower end of the connector 22. The diameter of the lower shell 21 is the same as the diameter of the beverage bottle connected to the instant beverage bottle cap, making the beverage bottle beautiful and simple as a whole;

[0039] refer to Figure 3 As shown, the poke cone 4 includes a cylindrical barrel and a conical puncture structure connected to a cylindrical bottom. A plurality of liquid outlet holes 42 are provided on the cylindrical barrel of the poke cone 4 and at the outer periphery connected to the conical puncture structure. At the same time, the cross-section of the conical puncture structure is cross-shaped, which can concentrate the force to quickly puncture the bottom of the melting cavity and allow the honey to flow into the bottle quickly. An annular flange 41 is provided on the upper part of the cylindrical barrel, and the annular flange 41 contacts the inner wall of the connector 22. An extrusion ring 11 is provided at the top inner end of the spiral cover 1, and the extrusion ring 11 is tightly attached to the annular flange 41. The rotation of the spiral cover 1 drives the extrusion ring 11 to squeeze the annular flange 41 to slide, thereby driving the poke cone 4 to slide in the connector 22. The conical puncture structure of the poke cone 4 punctures the bottom of the cavity 23, and the ingredients flow out.

[0040] The distance between the annular flange 41 and the limiting ring 25 when sliding in the connecting body 22 needs to ensure that the piercing cone 4 punctures the bottom opening of the cavity 23 to the maximum.

[0041] The bottom of the cavity 23 is an inclined end surface. The aluminum-plastic composite film commonly used in honey storage chambers can be localized with this inclined end surface, which, compared to the uniform force of a horizontal end surface, more easily breaks through the tensile strength of the sealing film, achieving rapid puncture. Furthermore, the inclined end surface allows the tip of the cone to first contact the sealing film with "line contact" or "small-area point contact." As the cone continues to apply pressure, the contact point gradually expands toward the periphery. Furthermore, the inclined end surface forms a natural diversion slope after puncture. Combined with the design of the liquid outlet 42 of the cone 4, this can reduce honey residue at the bottom of the cavity 23, further enhancing the thoroughness of the mixing of the contents.

[0042] refer to Figure 4 and 5 As shown, the outer wall of the spiral cover 1 is provided with anti-slip grooves, an inner ring 12 is provided at the inner end of the top of the spiral cover 1 and the inner side of the extrusion ring 11, and a reinforcing rib 13 is provided between the extrusion ring 11 and the inner ring 12. In view of the characteristics of the bottle cap such as thin wall, high frequency use and high sealing requirements, the rigidity, sealing and durability of the bottle cap can be guaranteed.

[0043] The inner wall of the lower cover 24 is provided with a thread for connecting to the bottle mouth of a beverage bottle.

[0044] refer to Figure 1 and Figure 6 As shown, a beverage bottle including the instant beverage bottle cap is provided with an external bottle thread 51 at the top of the bottle mouth 5 of the beverage bottle, which is screwed together with the thread of the lower cover body 24. A reinforcement ring 52 is provided at the middle and lower part of the bottle mouth 5. The bottle body of the beverage bottle is connected to the lower cover body 24 of the storage bottle cap via the bottle mouth external thread 51. Generally, beverage bottles are mostly made of plastic. The reinforcement ring 52 closely fits the outer wall of the bottle mouth 5 to form a "support section", shortening the effective cantilever length of the bottle mouth, dispersing the stress at the connection between the instant beverage bottle cap and the bottle mouth, and avoiding the risk of deformation and breakage caused by the bottle mouth being too high.

[0045] When it is necessary to prepare a beverage for drinking, tear off the pull ring 3, grab the screw cap 1 and rotate it. The screw cap 1 cooperates with the external threaded section on the outer periphery of the connector 22 to drive the screw cap 1 to move downward, and the extrusion ring 11 pushes the annular flange 41 to move downward, thereby driving the poke cone 4 to move downward until the annular flange 41 stops moving in the limit ring 25. During this process, the conical puncture structure of the poke cone 4 pierces the bottom of the dissolving cavity 23, and the honey in the dissolving cavity 23 flows into the bottle through the rupture. The bottle can also be shaken to allow water in the bottle to enter the lower cover 2 through the rupture for flushing, and the honey enters the bottle. After shaking well, the screw cap 1 is removed by rotating the screw cap in the opposite direction, and the mixed beverage flows out through the lower cover 2 and the poke cone 4 and is ready for drinking.

[0046] A filling method for the instant beverage bottle cap comprises the following steps:

[0047] Step 1: Honey pretreatment: Preheat the honey to 40-50℃ and place it in a vacuum environment of -0.08 to -0.09MPa for 15-30 minutes to allow bubbles to gather, burst and be discharged. Then filter it through an 80-120 mesh filter to remove impurities and pasteurize it at 55-60℃. Then quickly cool it to below 25℃ and seal it in a sterile environment.

[0048] Step 2: The ready-to-drink beverage bottle caps are passed through an automated cleaning line, sprayed with peracetic acid for disinfection, and then dried with hot air. After sterilization, the total number of microorganisms is ≤100 CFU / g. The sterilized ready-to-drink beverage bottle caps are immediately transferred to a clean workshop;

[0049] Step 3: Fix the lower cover 2 of the beverage bottle cap with an assembly line fixture in a clean workshop so that the filling port of the cavity 23 faces upward, ensuring that it is aligned with the center of the cavity during filling, and place the poke cone 4 in the connector 22 and the dissolving cavity 23;

[0050] Step 4: Based on the volume of the cavity 23 minus the volume of the piercing cone 4, the filling volume is preset and honey is filled using a screw pump filling machine;

[0051] Step 5: Use a servo capping machine to tighten the screw cap 1 and the pull ring 3 onto the connector 22 to obtain the instant beverage bottle cap filled with honey;

[0052] Step 6: After filling the honey, the instant beverage bottle caps are subjected to an inversion test including vibration, a positive and negative pressure test, and a liquid barrier test, and the instant beverage bottle caps that meet the requirements of 0% leakage rate, no bubbles under a positive pressure of 0.03MPa for 30 seconds, and no air infiltration under a negative pressure of -0.05MPa are selected;

[0053] Step 7: The screened instant beverage bottle cap is screwed onto the bottle filled with water through the lower cover 24 by a capping machine. The weight ratio of honey to water in the honey storage cavity is 1:10, and the filling process is completed.
