Description

Technical Field

[0001] The invention belongs to the technical field of beverage packaging, and in particular relates to an operating method for removing oxygen from a bottle cap. Background Art

[0002] Microorganisms inhabit nearly every corner of our daily lives and workplaces. These microorganisms, in various forms, adhere to the surfaces of solid objects or dissolve within liquid or gaseous fluids. As objects circulate, their species and numbers become increasingly complex. As these microorganisms continue to multiply and proliferate, they can cause changes in the objects themselves. Often, these changes are uncontrollable. Moreover, like other organisms, microbial growth and proliferation are highly dependent on oxygen.

[0003] During the packaging and production of beverages, microorganisms can multiply and reproduce within the product, causing the beverage to spoil. Extending the shelf life, especially for beverages stored at room temperature, is a systematic discipline. On the one hand, the beverage itself, the packaging materials, and the environment must be sterilized to reduce the number of microorganisms, especially harmful ones. This can be achieved through physical filtration sterilization, heat sterilization, and chemical sterilization. On the other hand, the caps of bottled beverages are mostly concave in shape, allowing for effective fixation and sealing using a boss, thread, or crimped edge. However, this concave shape can hinder gas flow, so during filling, it is necessary to reduce the oxygen content within the cap to slow or prevent the reproduction and proliferation of microorganisms. With the increasing focus on food health in recent years, reducing the use of antibacterial additives in beverages has become an inevitable trend. Extending shelf life in a safe and effective way is an urgent issue that needs to be addressed. Summary of the Invention

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] Example 1:

[0029] Wine, drinking water, and beverage bottles are mostly packaged by pressing caps and screwing caps. Usually, after the bottle caps are transported to a designated position through a capping channel, they are fitted to the bottle mouths by hanging caps or removing caps, and then transported to the next process after pressing caps or screwing caps. Therefore, an operating method for removing oxygen from bottle caps of the present invention includes a method for removing oxygen from bottle caps by hanging caps and a method for removing caps, wherein the bottle caps include drinking water bottle caps, beverage bottle caps, and wine bottle caps.

[0030] The bottle caps and bottle openings are fitted with aluminum caps and pull-ring caps by hanging the caps. Figure 5-6 As shown, the method for removing oxygen from bottle caps in a hanging cap manner includes: first forming a relatively sealed space inside the bottle cap conveying channel 1, then conveying multiple bottle caps side by side into the bottle cap conveying channel 1, then continuously inputting filtered, decompressed and pressure-stabilized carbon dioxide gas into the bottle cap conveying channel 1, and blowing the carbon dioxide gas obliquely upward into the bottle caps, so as to cause the carbon dioxide gas to replace the oxygen in the bottle caps, thereby discharging the oxygen in the bottle caps through the upper port of the bottle cap conveying channel 1. Since the density of carbon dioxide gas is greater than that of oxygen, the carbon dioxide gas will slowly settle downward due to its own weight and overflow from the lower port of the bottle cap conveying channel 1, thereby forming a carbon dioxide gas-intensive area inside the bottle cap conveying channel 1 and around the lower port of the bottle cap conveying channel 1, and finally the bottle caps flow out from the lower port of the bottle cap conveying channel 1 and are hung on the bottle mouth of the bottle body below it. This method can effectively reduce the oxygen content inside the bottle caps.

[0031] The bottle cap and the bottle mouth are fitted together by taking the cap, such as PET cap, yellow crown cap, etc. Figure 1-2 and Figure 5-6 As shown, the method for removing oxygen from bottle caps in a cap-removing manner includes: first, forming a relatively sealed space in the area between the position where the bottle body enters the turret 2 and the position where the bottle cap is pressed into the bottle mouth, then conveying multiple bottles side by side into the turret 2, and then, after the capping head 3 completes the cap removal, continuously inputting filtered, decompressed and pressure-stabilized carbon dioxide gas into the area between the position where the bottle body enters the turret 2 and the position where the bottle cap is pressed into the bottle mouth, and blowing the carbon dioxide gas obliquely upward toward the bottle cap to replace the oxygen in the bottle cap with carbon dioxide gas, and finally, the capping head 3 presses the bottle cap on the bottle mouth of the bottle body. This method can effectively reduce the oxygen content inside the bottle cap.

[0032] Example 2:

[0033] Based on Example 1 Figure 1-4As shown, the bottle cap conveying channel 1 is a conventional structure in this field; the bottle cap conveying channel 1 is arranged on the tangent line of the rotation center of the bottle body, and a cover shell 4 is fixedly installed on the outer periphery of the bottle cap conveying channel 1; the cover shell 4 is used to form a relatively sealed space inside the bottle cap conveying channel 1; a plurality of slots 401 are provided side by side on one side wall of the cover shell 4 from top to bottom; a bracket 5 with an L-shaped cross-section is screwed to the outer side of the slot 401; a first mounting block 6 is screwed to the bracket 5, and the first mounting block 6 can rotate around the screw thereon to adjust the installation direction of the first air nozzle 7; a first air nozzle 7 is fixed on the first mounting block 6; the outlet end of the first air nozzle 7 is arranged obliquely upward in the slot 401; the inlet end of the first air nozzle 7 is connected to a conventional first control valve 701 in this field; the first control valve 701 is used to control the blowing pressure in the first air nozzle 7. During use, the filtered, decompressed and stabilized carbon dioxide gas is delivered to the first gas nozzle 7 through the first control valve 701. The first gas nozzle 7 blows the carbon dioxide gas obliquely upward into the cover 4, thereby forming forced convection inside the bottle cap, and then replacing the oxygen in the bottle cap with carbon dioxide gas, which can effectively reduce the oxygen content inside the bottle cap.

[0034] Example 3:

[0035] Based on Example 2, Figure 5-6As shown, the turret 2 is a conventional structure in this field; a number of capping heads 3 are evenly arranged around the turret 2, and the center of the capping head 3 coincides with the rotation center of the bottle; the crown cap is transported to the cap removal position through the outer cap channel, and the capping head 3 completes the cap removal when it rotates with the turret 2 to the cap removal position. From the time the capping head 3 completes the cap removal to the time the bottle cap is pressed into the bottle mouth, the bottle cap is always exposed to the air; the inner guard plate of the bottleneck of the turret 2 is connected to the cylinder 8 by vertical screws; the outer guard plate of the bottleneck of the turret 2 is connected to the arc plate 9 arranged coaxially with the cylinder 8 by vertical screws; the arc plate 9 is arranged at Between the position where the bottle body enters the turret 2 and the position where the bottle cap is pressed into the bottle mouth; a relatively sealed space is formed between the curved plate 9 and the cylinder 8; a first blowing assembly 10 is installed on the lower surface of the ring of the turret 2; the first blowing assembly 10 is arranged between the capping head 3 and the curved plate 9; a second blowing assembly 11 and a third blowing assembly 12 are installed on the outer guard plate of the bottleneck of the turret 2; the second blowing assembly 11 is arranged between the curved plate 9 and the cylinder 9; the third blowing assembly 12 is arranged on one side of the curved plate 9 away from the capping head 3. During use, multiple bottles are transported side by side into the turret 2. After the capping head 3 completes removing the cap, the first blowing assembly 10 will blow out the oxygen inside the bottle cap and replace it with carbon dioxide gas. At this time, the oxygen content in the bottle cap is greatly reduced. When the capping head 3 enters the relatively closed space between the curved plate 9 and the cylinder 8 and before the bottle cap is pressed into the bottle mouth, the second blowing assembly 11 continues to spray carbon dioxide gas onto the bottle cap, which can continue to replace the oxygen inside the bottle cap with carbon dioxide gas, further reducing the oxygen content in the bottle cap. Finally, the third blowing assembly 12 blows carbon dioxide gas into the relatively sealed space between the curved plate 9 and the cylinder 8 in the opposite direction of rotation of the capping head 3, which can reduce the oxygen content in this space, and discharge the oxygen blown out of the bottle cap through the other side, which can effectively reduce the oxygen content inside the bottle cap.

[0036] Among them Figure 5 and Figure 7As shown, the first blowing assembly 10 includes a supporting bar 1001 connected to the lower surface of the turret ring 2 by a vertical screw; a straight slot is vertically opened at the lower end of the supporting bar 1001; a support rod 1002 is horizontally inserted in the straight slot; the support rod 1002 is fixed to the supporting bar 1001 by a pair of nuts, and the support rod 1002 can move up and down in the straight slot to adjust the blowing position; a second mounting block 1003 is fixed to the end of the support rod 1002 away from the supporting bar 1001; a first arc tube 1004 is horizontally fixed on the second mounting block 1003; a conventional second control valve 1005 in this field is connected to one end of the first arc tube 1004; a plurality of conventional second gas nozzles 1006 in this field are fixed side by side in a circular direction on the first arc tube 1004; the outlet end of the second gas nozzle 1006 is tilted upward to point to the bottle cap; the second control valve 1005 is used to control the blowing pressure in the second gas nozzle 1006. When in use, the carbon dioxide gas is transported into the first arc tube 1004 through the second control valve 1005, and the carbon dioxide gas is blown upwardly into the bottle cap through the second gas nozzle 1006, thereby achieving a one-time replacement of the oxygen in the bottle cap, which can effectively reduce the oxygen content inside the bottle cap.

[0037] Among them Figure 6 and Figure 8 As shown, the second blowing assembly 11 includes a pair of third mounting blocks 1101 connected to the outer guard plate of the bottleneck of the turret 2 by screws in parallel; a accommodating groove is provided on the outer guard plate of the bottleneck of the turret 2 along the radial direction of its rotation center; the third mounting block 1101 is screwed into the accommodating groove, and this structure can achieve adjustment of the blowing position by adjusting the position of the third mounting block 1101; the two third mounting blocks 1101 are connected by a second arc tube 1102; one end of the second arc tube 1102 is connected to a conventional third control valve 1103 in this field; a plurality of conventional third gas nozzles 1104 in this field are fixed side by side along a circular direction on the second arc tube 1102; the outlet end of the third gas nozzle 1104 is tilted upward to point to the bottle cap; the third control valve 1103 is used to control the blowing pressure in the third gas nozzle 1104. During use, the carbon dioxide gas is transported into the second arc tube 1102 through the third control valve 1103 and blown obliquely upward into the bottle cap through the third gas nozzle 1104, thereby achieving a one-time replacement of the oxygen in the bottle cap, which can effectively reduce the oxygen content inside the bottle cap.

[0038] Among them Figure 6 and Figure 9As shown, the third air blowing assembly 12 includes a fourth mounting block 1201 screwed to the outer protective plate of the neck of the turret 2; the position of the fourth mounting block 1201 on the outer protective plate of the neck of the turret 2 is adjustable; a fourth air nozzle 1202, conventional in the art, is horizontally fixed to the fourth mounting block 1201; the outlet end of the fourth air nozzle 1202 is inserted between the curved plate 9 and the cylinder 9; the inlet end of the fourth air nozzle 1202 is connected to a fourth control valve 1203, conventional in the art; and the fourth control valve 1203 is used to control the air pressure within the fourth air nozzle 1202. During use, carbon dioxide gas is delivered to the fourth air nozzle 1202 through the fourth control valve 1203. The fourth air nozzle 1202 blows the carbon dioxide gas into the relatively sealed space between the curved plate 9 and the cylinder 8 against the direction of rotation of the capping head 3, thereby reducing the oxygen content in this space. The oxygen blown out of the bottle cap is discharged through the other side, effectively reducing the oxygen content inside the bottle cap.
