Description

Technical Field

[0001] The patent of this invention relates to the technical field of hydrogen beverages, specifically, to a method for packaging hydrogen beverages in full cans with increased hydrogen content. Background Art

[0002] As an emerging functional beverage, hydrogen drinks have gradually attracted attention in the market in recent years. Hydrogen has multiple physiological functions such as antioxidant and anti-inflammatory, so hydrogen drinks are considered to have certain health benefits.

[0003] However, the particularity of hydrogen beverages lies in the hydrogen dissolved in the beverage, which easily escapes during the filling process. This process is directly related to the amount of hydrogen retained in the beverage and the quality stability of the product.

[0004] In existing technologies, beverage filling is mostly done in a partially filled can, meaning the can is filled to a certain height, leaving a certain amount of headspace before capping. However, for hydrogen beverages, hydrogen is a light gas with relatively low solubility in beverages and easily escapes. When the can is partially filled, the environment between the beverage and the hydrogen is relatively open, and hydrogen easily separates from the beverage and escapes into the headspace, resulting in a decrease in the hydrogen content in the beverage and affecting the product's efficacy. Moreover, the existence of the headspace may cause the beverage to be affected by external environmental factors during storage and transportation, such as temperature changes and vibrations, further exacerbating the escape of hydrogen and reducing the quality and stability of hydrogen beverages. Summary of the Invention

[0005] The purpose of the present invention is to provide a method for packaging hydrogen beverages in full cans with increased hydrogen content, aiming to solve the problem in the prior art that the beverage and hydrogen are easily separated when the hydrogen beverage is not fully filled.

[0006] The present invention is achieved by a method for packaging a full can of hydrogen beverage with increased hydrogen content, comprising the following steps: 1) The beverage can is moved to a filling station, where a filling pipe is provided. The beverage can has a tank cavity with a top opening. The filling pipe injects hydrogen beverage into the tank cavity until the tank cavity is completely filled with hydrogen beverage, and the hydrogen beverage has an overflow portion above the top opening. 2) The beverage can filled with hydrogen beverage moves to the cover lowering station, which has a cover lowering rack with a can lid mounted therein. When the beverage can is positioned below the cover lowering rack, the can lid falls onto the overflow portion and is supported by the overflow portion to float above the top opening of the beverage can. 3) The beverage can and the can lid in a suspended state are synchronously moved to a packaging station having a rotating head. When the beverage can and the can lid are synchronously moved to the bottom of the rotating head, the rotating head presses the can lid downward until the can lid seals the top opening. After the overflow portion is squeezed and overflows outward, the rotating head rotates to fix the can lid and the beverage can together, and the can lid seals the top opening.

[0007] Furthermore, in step 1), the filling tube has a downwardly arranged filling port. When the beverage can is moved below the filling port, the filling port is located above the top opening, and the hydrogen beverage in the filling tube is injected into the tank cavity through the filling port.

[0008] Furthermore, in step 1), during the process of injecting the hydrogen beverage into the tank cavity through the injection tube, the injection tube maintains a set flow rate to inject the hydrogen beverage into the tank cavity until the hydrogen beverage in the tank cavity reaches a set height. Thereafter, the injection tube intermittently injects the hydrogen beverage into the tank cavity until the tank cavity is filled with the hydrogen beverage and an overflow portion is formed.

[0010] Furthermore, the outer periphery of the central portion is formed with an annular portion extending upward, the annular portion is arranged around the outer periphery of the central portion, the outer peripheral portion is connected to the annular portion, and is located above the central portion; in the step 3), the rotating head presses downward against the can cover, the central portion moves downward, passes through the top opening, and is embedded in the can cavity, and the annular plate is inserted into the top opening until the outer peripheral portion abuts against the beverage can.

[0011] Furthermore, the outer peripheral portion is curved to enclose an annular groove, the annular groove is arranged around the circumference of the central portion, and the top of the beverage can has an annular top edge, the top edge is arranged around the outer circumference of the top opening; In step 2), the rotating head presses downward against the can cover, and the central portion is embedded in the can cavity until the top edge is embedded in the annular groove; in step 3), when the top edge is embedded in the annular groove and abuts against the outer peripheral portion, the rotating head rotates horizontally in situ to clamp and deform the outer peripheral portion, so that the outer peripheral portion fixes and clamps the top edge, so that the outer peripheral portion is fixedly connected to the beverage can as a whole.

[0012] Furthermore, the lower end of the annular portion is connected to the outer periphery of the central portion, the upper end of the annular portion extends upward, and the outer peripheral portion is connected to the upper end of the annular portion and extends outward away from the annular portion; a positioning groove is provided between the central portion and the annular portion and is open upward, and the positioning groove is arranged around the outer periphery of the central portion; In the step 2), a positioning ring is extended downward from the outer periphery of the rotating head, and the positioning ring is arranged around the outer periphery of the rotating head. A plurality of swinging heads are provided on the outer periphery of the rotating head; when the rotating head presses the can cover and moves downward, the positioning ring is embedded in the positioning groove, and the plurality of swinging heads deviate from the rotating head and swing outward; when the top edge is embedded in the annular groove and abuts against the outer periphery, the swinging head swings inward toward the rotating head, clamping and deforming the outer periphery, and the rotating head rotates horizontally in situ, and the plurality of swinging heads clamp and deform the entire outer periphery, so that the outer periphery fixes the top edge, so that the outer periphery is fixedly connected to the beverage can as a whole.

[0013] Furthermore, in step 1), when the beverage can is placed on the liquid filling station, the beverage can is placed in the lower moving head, the side of the lower moving head is recessed to form a lower restriction area with an open side, and the beverage can is arranged longitudinally and embedded in the lower restriction area; when the tank cavity is filled with hydrogen beverage, the lower moving head drives the beverage can to move linearly to the lower cover station; In step 2), an upper moving head is provided on the lower moving head, and the side of the upper moving head is recessed to form an upper restricted area with a side opening; when the can lid falls on the overflow portion, the can lid is located in the upper restricted area, and the upper moving head moves synchronously with the lower moving head to synchronously move the beverage can and the can lid on the lower cover station to the packaging station.

[0014] Furthermore, in step 1), the injection pipe is connected to the liquid storage tank through a rotary spray structure, the liquid storage tank is connected to a liquid inlet pipe, the injection pipe is connected to a liquid outlet pipe, the rotary spray structure is connected to the liquid storage tank through the liquid inlet pipe, and the rotary spray structure is connected to the injection pipe through the liquid outlet pipe; The rotary spray structure has a plurality of branch flow channels, the diameter of each branch flow channel is smaller than the diameter of the liquid inlet pipe; the plurality of branch flow channels are independently arranged between the liquid inlet pipe and the liquid outlet pipe, the plurality of branch flow channels are connected to the liquid inlet pipe, and the plurality of branch flow channels are connected to the liquid outlet pipe; During the process of injecting the hydrogen beverage into the tank cavity through the injection pipe, the hydrogen beverage in the liquid storage tank passes through the liquid inlet pipe, multiple branch flow channels, the liquid outlet pipe and the injection pipe in sequence, and is then injected into the tank cavity through the injection pipe; during the process of the hydrogen beverage entering the multiple branch flow channels from the liquid inlet pipe, the flow rate of the hydrogen beverage decreases, and the pressure in the liquid inlet pipe and the liquid storage tank increases.

[0015] Furthermore, in step 1), the middle portion of the branch flow channel expands outward to form a spherical area, wherein a rolling suspension ball is provided in the spherical area, wherein the diameter of the suspension ball is smaller than the diameter of the spherical area, and a spherical gap is formed between the outer periphery of the suspension ball and the spherical area, wherein the suspension ball is provided with a plurality of diameter flow channels, wherein the plurality of diameter flow channels penetrate the suspension ball and are arranged along the radial direction of the suspension ball; As the hydrogen beverage passes through the branch flow channel, the suspended ball is suspended in the spherical area. The hydrogen beverage impacts the suspended ball, causing the suspended ball to roll in multiple directions in the spherical area. The hydrogen beverage passes through the spherical gap and multiple diameter flow channels, impacting the suspended ball in multiple directions.

[0016] Compared with the prior art, the method for packaging a full can of hydrogen beverage with increased hydrogen content provided by the present invention significantly improves the hydrogen retention rate in the hydrogen beverage through specific filling steps. Specifically, the following points are achieved: 1) In the first step, the beverage can moves to the filling station, and the filling pipe injects the hydrogen beverage into the tank cavity until the tank cavity is filled with hydrogen beverage and an overflow is formed. This ensures that the hydrogen beverage is always full during the filling process, avoiding the problem of hydrogen gas escaping due to the existence of the head space. The overflow also provides the basic conditions for the subsequent tank cover support. 2) In the second step, the full hydrogen beverage can moves to the lower cover station, where the can lid falls onto the overflow and is supported by it to float above the top opening of the tank cavity. This utilizes the surface tension of the liquid in the overflow to keep the can lid stably suspended above the beverage before capping, further reducing the chance of hydrogen coming into contact with the outside air. This is significantly different from the partially filled can filling method. In addition, the suspended state of the can lid facilitates subsequent packaging operations and also ensures the retention of hydrogen. 3) In the third step, the rotating head presses the can lid downward until the top opening is sealed. At this time, the overflow part is squeezed and overflows outward. The rotating head continues to rotate, and finally the can lid completes the closure of the top opening. During this process, the overflow of the overflow part and the sealing operation of the can lid are closely connected, ensuring that hydrogen will not escape in large quantities due to pressure changes at the moment of sealing, further reducing the separation of the beverage and hydrogen, thereby improving the quality and stability of the hydrogen beverage.

[0021] Reference Figure 1-8 The figure shows a preferred embodiment of the present invention.

[0022] A method for packaging a full can of hydrogen beverage with increased hydrogen content comprises the following steps: 1) The beverage can 101 is moved to the filling station, where a filling pipe 100 is provided. The beverage can 101 has a tank cavity with a top opening. The filling pipe 100 injects hydrogen beverage into the tank cavity until the tank cavity is completely filled with hydrogen beverage, and the hydrogen beverage has an overflow portion 103 above the top opening. 2) The full hydrogen beverage can 101 moves to the cover lowering station, which has a cover lowering rack 300 with a can lid 301 mounted therein. When the beverage can 101 is positioned below the cover lowering rack 300, the can lid 301 falls onto the overflow portion 103 and is supported by the overflow portion 103 to float above the top opening of the beverage can 101. 3) The beverage can 101 and the can lid 301 in a suspended state are synchronously moved to the packaging station, which has a rotating head 302. When the beverage can 101 and the can lid 301 are synchronously moved to the bottom of the rotating head 302, the rotating head 302 presses the can lid 301 downward until the can lid 301 covers the top opening. After the overflow portion 103 is squeezed and overflows outward, the rotating head 302 rotates to fix the can lid 301 and the beverage can 101 together, and the can lid 301 closes the top opening.

[0023] The above-mentioned method for packaging a full can of hydrogen beverage with increased hydrogen content significantly improves the hydrogen retention rate in the hydrogen beverage through specific filling steps. Specifically, the following points are achieved: 1) In the first step, the beverage can moves to the filling station, and the filling pipe injects the hydrogen beverage into the tank cavity until the tank cavity is filled with hydrogen beverage and an overflow is formed. This ensures that the hydrogen beverage is always full during the filling process, avoiding the problem of hydrogen gas escaping due to the existence of the head space. The overflow also provides the basic conditions for the subsequent tank cover support. 2) In the second step, the full hydrogen beverage can moves to the lower cover station, where the can lid falls onto the overflow and is supported by it to float above the top opening of the tank cavity. This utilizes the surface tension of the liquid in the overflow to keep the can lid stably suspended above the beverage before capping, further reducing the chance of hydrogen coming into contact with the outside air. This is significantly different from the partially filled can filling method. In addition, the suspended state of the can lid facilitates subsequent packaging operations and also ensures the retention of hydrogen. 3) In the third step, the rotating head presses the can lid downward until the top opening is sealed. At this time, the overflow part is squeezed and overflows outward. The rotating head continues to rotate, and finally the can lid completes the closure of the top opening. During this process, the overflow of the overflow part and the sealing operation of the can lid are closely connected, ensuring that hydrogen will not escape in large quantities due to pressure changes at the moment of sealing, further reducing the separation of the beverage and hydrogen, thereby improving the quality and stability of the hydrogen beverage.

[0024] In this embodiment, in step 1), the filling tube 100 has a downwardly arranged filling port 104. When the beverage can 101 moves below the filling port 104, the filling port 104 is located above the top opening, and the hydrogen beverage in the filling tube 100 is injected into the tank cavity through the filling port 104.

[0025] In this way, the hydrogen beverage is accurately injected into the tank cavity, ensuring that the hydrogen beverage can smoothly fill the tank cavity, creating conditions for the subsequent formation of the overflow portion 103, and laying the foundation for solving the problem of easy separation of the beverage and hydrogen when the tank is not full.

[0026] In this embodiment, in step 1), during the process of the injection tube 100 injecting the hydrogen beverage into the tank cavity, the injection tube 100 maintains a set flow rate to inject the hydrogen beverage into the tank cavity until the hydrogen beverage in the tank cavity reaches a set height. Then, the injection tube 100 intermittently injects the hydrogen beverage into the tank cavity until the tank cavity is filled with the hydrogen beverage and the hydrogen beverage forms an overflow portion 103.

[0027] By maintaining a set flow rate to inject the hydrogen beverage, it is possible to ensure that the hydrogen beverage is smoothly filled in the tank cavity, thereby preventing hydrogen gas from escaping or beverage splashing due to an excessively fast flow rate. When the hydrogen beverage in the tank cavity reaches a set height, intermittent injection is used to further stabilize the hydrogen beverage in the tank cavity, allowing it to smoothly form the overflow portion 103. The overflow portion 103 can effectively reduce the channels for hydrogen to escape, allowing hydrogen to be better dissolved in the hydrogen beverage, thereby significantly improving the retention rate of hydrogen in the hydrogen beverage.

[0028] In this embodiment, the can cover 301 includes a central portion 400, and the outer periphery of the central portion 400 is surrounded by the outer periphery 401, and the central portion 400 is arched upward to form a raised groove 402 with a bottom opening; in step 2), when the can cover 301 falls on the overflow portion 103, the overflow portion 103 is embedded in the raised groove 402, supporting the can cover 301 to float above the top opening; in step 3), the rotating head 302 rotates to fix the outer periphery 401 and the beverage can 101 into one.

[0029] By utilizing the surface tension of the overflow portion 103, the can lid 301 can be stably suspended above the top opening. When the rotating head 302 fixedly connects the outer peripheral portion 401 and the beverage can 101 as a whole, the can lid 301 can tightly seal the top opening, further reducing the possibility of hydrogen leakage. This not only improves the sealing between the can lid 301 and the beverage can 101, but also provides reliable protection for the packaging of hydrogen beverages.

[0030] In this embodiment, an annular portion 403 extending upward is formed on the outer periphery of the central portion 400, and the annular portion 403 is arranged around the outer periphery of the central portion 400. The peripheral portion 401 is connected to the annular portion 403 and is located above the central portion 400; in step 3), the rotating head 302 presses the can cover 301 downward, and the central portion 400 moves downward, passes through the top opening, and is embedded in the can cavity. The annular plate is inserted into the top opening until the peripheral portion 401 abuts against the beverage can.

[0031] When the central portion 400 passes through the top opening and is embedded in the tank cavity, the annular portion 403 is passed through the top opening, which can better guide the connection between the tank cover 301 and the beverage can 101, so that the peripheral portion 401 can accurately abut against the beverage can, which helps to improve the connection accuracy and sealing between the tank cover 301 and the beverage can 101, and improves the packaging quality and stability of the hydrogen beverage.

[0032] In this embodiment, the outer peripheral portion 401 is curved and encloses an annular groove 404. The annular groove 404 is arranged around the circumference of the central portion 400. The top of the beverage can 101 has an annular top edge 102. The top edge 102 is arranged around the outer circumference of the top opening. In step 2), the rotating head 302 presses downward against the can cover 301, and the central portion 400 is embedded in the can cavity until the top edge 102 is embedded in the annular groove 404; in step 3), when the top edge 102 is embedded in the annular groove 404 and abuts against the peripheral portion 401, the rotating head 302 rotates horizontally in situ, clamping and deforming the peripheral portion 401, so that the peripheral portion 401 fixes the top edge 102, so that the peripheral portion 401 is fixedly connected to the beverage can 101 as a whole.

[0033] By utilizing the curved arrangement of the outer periphery 401 and the guiding effect of the annular groove 404, when the top edge 102 is embedded in the annular groove 404, the in-situ horizontal rotation of the rotating head 302 can cause the outer periphery 401 to be clamped and deformed, thereby firmly clamping the top edge 102 between the outer periphery 401 and the annular groove 404, thereby improving the connection strength and sealing between the can cover 301 and the beverage can 101, and can also effectively prevent the can cover 301 from loosening or falling off during subsequent use.

[0034] In this embodiment, the lower end of the annular portion 403 is connected to the outer periphery of the central portion 400, the upper end of the annular portion 403 extends upward, and the peripheral portion 401 is connected to the upper end of the annular portion 403 and extends outward away from the annular portion 403. A positioning groove 405 is provided between the central portion 400 and the annular portion 403 and is open upward. The positioning groove 405 is arranged around the outer periphery of the central portion 400. In step 2), a positioning ring 303 extends downward from the outer periphery of the rotating head 302, and the positioning ring 303 is arranged around the outer periphery of the rotating head 302, and a plurality of swinging heads 304 are provided on the outer periphery of the rotating head 302; when the rotating head 302 presses the can cover 301 and moves downward, the positioning ring 303 is embedded in the positioning groove 405, and the plurality of swinging heads 304 deviate from the rotating head 302 and swing outward; when the top edge 102 is embedded in the annular groove 404 and abuts against the outer periphery 401, the swinging heads 304 swing inward toward the rotating head 302, clamping and deforming the outer periphery 401, and the rotating head 302 rotates horizontally in situ, and the plurality of swinging heads 304 clamp and deform the entire outer periphery 401, so that the outer periphery 401 fixes and clamps the top edge 102, so that the outer periphery 401 and the beverage can 101 are fixedly connected as one.

[0035] By utilizing the positioning function of the positioning groove 405 and the positioning ring 303, when the positioning ring 303 is inserted into the positioning groove 405, the plurality of swing heads 304 can accurately deviate from the rotating head 302 and swing outward, thereby providing space for subsequent clamping and deformation operations; When the top edge 102 is embedded in the annular groove 404, the swing head 304 swings inward, clamping and deforming the outer peripheral portion 401. The in-situ horizontal rotation of the rotating head 302 further strengthens the fixed connection between the outer peripheral portion 401 and the top edge 102. This not only improves the connection accuracy and sealing between the can cover 301 and the beverage can 101, but also effectively prevents the can cover 301 from loosening or falling off during subsequent use, further reducing the possibility of hydrogen leakage.

[0036] In this embodiment, in step 1), when the beverage can 101 is placed on the filling station, it is placed in the lower moving head 105. The side of the lower moving head 105 is recessed to form a lower restricted area 106 with an open side. The beverage can 101 is arranged longitudinally and embedded in the lower restricted area 106. When the tank cavity is filled with hydrogen beverage, the lower moving head 105 drives the beverage can 101 to move linearly to the lower cover station. In step 2), an upper moving head 107 is provided on the lower moving head 105, and the side of the upper moving head 107 is recessed to form an upper restricted area with an open side; when the can lid 301 falls on the overflow portion 103, the can lid 301 is located in the upper restricted area, and the upper moving head 107 moves synchronously with the lower moving head 105, synchronously moving the beverage can 101 and the can lid 301 on the lower cover station to the packaging station.

[0037] By setting up a moving head, the beverage can 101 and the can cover 301 can move smoothly between various workstations, avoiding shaking or deviation of the beverage can 101 and the can cover 301 during the movement, thereby ensuring the stability and reliability of the entire filling process and further improving the packaging quality and stability of the hydrogen beverage.

[0038] In this embodiment, in step 1), the injection pipe 100 is connected to the liquid storage tank through the rotary spray structure, the liquid storage tank is connected to the liquid inlet pipe 200, the injection pipe 100 is connected to the liquid outlet pipe 201, the rotary spray structure is connected to the liquid storage tank through the liquid inlet pipe 200, and the rotary spray structure is connected to the injection pipe 100 through the liquid outlet pipe 201; The rotary spray structure has multiple branch flow channels 202, and the diameter of the branch flow channels 202 is smaller than the diameter of the liquid inlet pipe 200; the multiple branch flow channels 202 are independently arranged between the liquid inlet pipe 200 and the liquid outlet pipe 201, and the multiple branch flow channels 202 are connected to the liquid inlet pipe 200, and the multiple branch flow channels 202 are connected to the liquid outlet pipe 201; During the process of injecting hydrogen beverage into the tank cavity through the liquid injection pipe 100, the hydrogen beverage in the liquid storage tank passes through the liquid inlet pipe 200, multiple branch flow channels 202, the liquid outlet pipe 201 and the liquid injection pipe 100 in sequence, and is then injected into the tank cavity through the liquid injection pipe 100; during the process of the hydrogen beverage entering the multiple branch flow channels 202 from the liquid inlet pipe 200, the flow rate of the hydrogen beverage decreases, and the pressure in the liquid inlet pipe 200 and the liquid storage tank increases.

[0039] The rotary spray structure can effectively control the injection flow rate and pressure of the hydrogen beverage. The diversion effect of multiple branch flow channels 202 reduces the flow rate of the hydrogen beverage before it enters the injection pipe, thereby avoiding the occurrence of hydrogen gas leakage or beverage splashing due to excessive flow rate. At the same time, the increased pressure in the liquid inlet pipe 200 and the liquid storage tank helps to improve the filling efficiency of the hydrogen beverage in the tank cavity and ensure that the hydrogen beverage can be more evenly distributed in the entire tank cavity. This not only improves the stability and reliability of the filling process, but also effectively reduces the escape of hydrogen during the filling process, thereby improving the retention rate of hydrogen in the hydrogen beverage.

[0040] In this embodiment, in step 1), the middle portion of the branch flow channel 202 expands outward to form a spherical area 203 in the shape of a sphere. A rolling suspension ball 204 is provided in the spherical area 203. The diameter of the suspension ball 204 is smaller than the diameter of the spherical area 203. A spherical gap 205 is defined between the outer periphery of the suspension ball 204 and the spherical area 203. The suspension ball 204 is provided with a plurality of diameter flow channels 206. The plurality of diameter flow channels 206 penetrate the suspension ball 204 and extend radially along the suspension ball 204. As the hydrogen beverage passes through the branch flow channel 202, the suspended ball 204 moves and suspends in the spherical area 203. The hydrogen beverage impacts the suspended ball 204, causing the suspended ball 204 to roll in multiple directions in the spherical area 203. The hydrogen beverage passes through the spherical gap 205 and multiple diameter flow channels 206, impacting the suspended ball 204 in multiple directions.

[0041] The suspended ball 204 is impacted by the hydrogen beverage in the spherical area 203, so that the suspended ball 204 is in an active suspended state in the spherical area 203, so that the hydrogen beverage can pass through the spherical gap 205 and the multiple diameter flow channels 206, and the suspended ball 204 is in an active rolling state. According to the pressure changes of the liquid inlet pipe 200 and the liquid storage tank, and the active rolling state of the suspended ball 204, the speed and flow rate of the hydrogen beverage through the branch flow channel 202 are realized, and the effect of automatic flow rate change and regulation is achieved to avoid blockage and ensure that a sufficient pressure difference is maintained between the liquid inlet pipe 200 and the liquid outlet pipe 201.

[0042] In addition, multiple diameter flow channels 206 are formed in the suspension ball 204, and the diameter flow channels 206 pass through the center position of the suspension ball 204. In this way, the hydrogen beverage can achieve multi-directional impact on the suspension ball 204 during the process of passing through the diameter flow channels 206 of the suspension ball 204, so as to keep the suspension ball 204 in a real-time dynamic rolling state.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
