Description

wine bottle

[0001] This application claims priority to Chinese patent application No. 202310768664.1 filed on June 26, 2023, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of liquid storage devices, and in particular to a wine bottle. Background Art

[0003] In existing bottles for storing red wine, champagne and other liquors, wooden corks are usually pressed directly into the bottle mouth to block and seal the bottle. The tiny pores in the wooden corks allow trace amounts of gas to enter and exit the bottle, allowing the sealed wine to continue to ferment and mature in the trace gas environment, making the flavor of the wine become more mellow as the storage years increase.

[0004] However, when using wooden corks to seal bottles, tools are required to remove the cork when opening the bottle, making it inconvenient to open the bottle. Furthermore, the cork expands after being removed, making it difficult to properly insert the cork back into the bottle mouth for secondary sealing, making it inconvenient to store the bottle after opening. Furthermore, using tools to remove the wooden cork often causes it to break, which can easily cause cork fragments to fall into the wine, affecting the taste of the wine and reducing the user's drinking experience.

[0034] In existing wine bottles for storing red wine, champagne and other liquors, wooden corks are usually directly pressed into the bottle mouth to block and seal the bottle. The tiny pores in the wooden corks allow trace amounts of gas to enter and exit the bottle, allowing the sealed wine to continue to ferment and mature in a trace gas environment, making the flavor of the wine more mellow as the storage period increases. However, when using wooden corks to seal the bottle, it is necessary to use a tool to pull out the cork when opening the bottle, which makes the operation of opening the bottle inconvenient. Moreover, the cork will expand and become larger after being pulled out, resulting in the cork being unable to be properly stuffed back into the bottle mouth for secondary sealing, which is inconvenient for storing the bottle after opening. The process of using a tool to pull out the wooden cork usually causes the wooden cork to break, which can easily cause cork fragments to fall into the wine, thereby affecting the taste of the wine and reducing the user's drinking experience. In response to the above problems, the present application proposes a wine bottle 1000.

[0035] 1 to 5, in the embodiment of the present application, the wine bottle 1000 includes a bottle body 100, a bottle stopper 300 and a cork 500. The bottle body 100 is provided with a liquid storage cavity 11, and one end of the bottle body 100 is provided with a sealing hole 13 connected to the liquid storage cavity 11; the bottle stopper 300 is movably connected to the bottle body 100, and opens or closes the sealing hole 13 during the movement. The bottle stopper 300 is provided with a plunger portion 30a, and the plunger portion 30 a is inserted into the sealing hole 13 and abuts against the inner wall of the sealing hole 13. A accommodating cavity 34 is formed in the plunger portion 30a. The plunger portion 30a is provided with a contact port 341 and an air flow hole 325 communicating with the accommodating cavity 34. The contact port 341 is exposed to the liquid storage cavity 11, and one end of the air flow hole 325 is exposed to the end face of the bottle stopper 300 facing away from the bottle body 100. The wooden plug 500 is arranged in the accommodating cavity 34 and abuts against the inner wall of the accommodating cavity 34.

[0036] It is understandable that when the wine bottle 1000 stores red wine, champagne and other wines with a certain fragrance, the bottle mouth of the wine bottle 1000 is sealed with a wooden plunger supported by compression of cork materials such as natural oak or mixed wood chips. The tiny pores in the wooden plunger can be used to achieve the exchange of trace gases inside and outside the wine bottle 1000, so that the wine can further ferment in a weak oxygen environment, which is conducive to making the flavor of the wine more mellow and fragrant during long-term storage, thereby improving the tasting experience and economy of the wine. In the related art, a wooden plunger is usually compressed and pressed into the mouth of the wine bottle 1000 to seal the wine bottle 1000. When the wine bottle 1000 is opened, a tool is inserted into the wooden plunger and then the tool is used to lift and pull out the wooden plunger to open the wine bottle 1000. When the wooden plunger is pulled out, the wooden plunger will rapidly expand and become larger after being pulled out due to the wooden plunger recovering its elastic deformation or due to the wooden plunger absorbing part of the wine, which makes it impossible for the wooden plunger to be easily inserted into the mouth of the wine bottle 1000 again to store the wine.

[0037] In the present application, the bottle stopper 300 can be made of a plastic material or a metal material with relatively stable chemical properties. At this time, the outer peripheral side of the plunger part 30a can be provided with a soft rubber layer with certain elasticity and stable chemical properties, or the overall structure of the plunger part 30a can be made of a soft rubber material with certain elasticity and stable chemical properties, so that the plunger part 30a can use its own elasticity to more conveniently insert into the sealing hole 13 of the wine bottle 1000, and use the effect of elasticity to more stably abut the inner wall of the sealing hole 13 to achieve a better sealing effect of the wine bottle 1000. By providing a receiving cavity 34 in the plunger portion 30a, and providing a contact port 341 and an air flow hole 325 communicating with the receiving cavity 34 at opposite ends of the plunger portion 30a, the contact port 341 is exposed in the liquid storage cavity 11, and the air flow hole 325 is exposed at the end of the plunger portion 30a facing away from the bottle body 100, so that the contact port 341, the receiving cavity 34 and the air flow hole 325 can form a certain air flow channel in the plunger portion 30a, which facilitates the exchange of gas in the liquid storage cavity 11 and gas outside the bottle body 100; at this time, by pressing or filling the wooden plug 500 into the receiving cavity 34, the wooden plug 500 abuts against the inner wall of the receiving cavity 34 to block the gas. The air flow channel is formed in the plunger portion 30a. The overall material of the cork piece 500 can be natural oak or mixed wood chips and other cork materials. Then, by utilizing the tiny pores formed inside the cork piece 500 itself, the air in the liquid storage chamber 11 and outside the bottle can circulate through the contact port 341, the tiny pores in the cork piece 500 and the air flow holes 325, ensuring that when the bottle body 100 stores wine, the plunger portion 30a is used to allow the liquid storage chamber 11 to maintain trace gas exchange and flow with the gas outside the bottle, so that a micro-oxygen storage environment is formed in the liquid storage chamber 11, which is conducive to further fermentation of the wine when stored in the wine bottle 1000, thereby improving the flavor of the wine stored for a long time. Since the pores in the cork 500 are relatively fine and tiny, only air molecules with a smaller diameter can pass through the cork 500, preventing the wine from flowing out of the wine bottle 1000 through the cork 500 when the wine bottle 1000 is overturned, thereby ensuring the sealed storage effect of the wine bottle 1000. After the wine moistens the cork 500, the cork 500 can absorb water and expand, maintaining a close contact between the cork 500 and the inner wall of the accommodating cavity 34, which is conducive to better improving the storage effect of the wine bottle 1000 and improving the practicality and reliability of the wine bottle 1000.

[0038] In the present application, the bottle stopper 300 is moved on the bottle body 100 to open or cover the sealing hole 13 to realize opening or closing of the wine bottle 1000. The bottle stopper 300 and the bottle body 100 can be fastened by using a fastener, or the bottle stopper 300 can be unscrewed or tightened by setting a thread between the bottle stopper 300 and the bottle body 100, or the plunger part 30a can be tightly fitted and fixed with the sealing hole 13, thereby realizing the covering and opening of the bottle stopper 300 and the bottle body 100, thereby ensuring convenient opening and sealed storage of the wine bottle 1000. Since the plunger portion 30a is provided on the cork 300 to accommodate and fix the cork piece 500, after the wine bottle 1000 is opened and the cork 300 is pulled out, the fixing action of the plunger portion 30a can effectively prevent the cork piece 500 from expanding and squeezing the cork 300 to deform, so that the cork 300 can maintain a stable structure without change. Furthermore, after the cork 300 is pulled out, the cork 300 can be easily moved to the bottle body 100 again to cover the sealing hole 13, and the plunger portion 30a can be stably inserted in the sealing hole 13 again to abut against the inner wall of the sealing hole 13, thereby effectively improving the operation convenience and practicality of the wine bottle 1000. With the cork 300 accommodating and fixing the cork piece 500, the cork 300 and the bottle body 100 can be conveniently opened and sealed by means of a snap, a thread or a plunger, so that the wine bottle 1000 does not need to be opened with the aid of tools, effectively preventing the cork piece 500 from being damaged, and preventing debris of the cork piece 500 from falling into the liquid storage chamber 11 and affecting the drinking taste of the wine, thereby further improving the structural stability and reliability of the wine bottle 1000.

[0039] The present invention provides a plunger portion 30a on the bottle stopper 300. When the bottle stopper 300 is movably connected to the bottle body 100 to cover the sealing hole 13, the plunger portion 30a is inserted into the sealing hole 13 and abuts against the inner wall of the sealing hole 13, thereby ensuring the sealed storage effect of the wine bottle 1000. Furthermore, by providing a receiving cavity 34 within the plunger portion 30a and providing a contact port 341 on the plunger portion 30a to connect the receiving cavity 34 with the airflow hole 325, the contact port 341 is exposed in the liquid storage cavity 11, and the airflow hole 325 is exposed on the end surface of the bottle stopper 300 facing away from the bottle body 100. Thus, the airflow hole 325, the receiving cavity 34, and the contact port 341 form an air passage in the bottle stopper 300, connecting the liquid storage cavity 11 with the outside of the bottle. By arranging a cork 500 in the accommodating cavity 34 and making the cork 500 fill the accommodating cavity 34 and abut against the inner wall of the accommodating cavity 34, the tiny pores in the cork 500 can be used to realize the flow of trace gases in and out of the bottle, so that when the wine bottle 1000 stores red wine, champagne and other wines, the wine can continue to ferment and mature in a trace gas environment, which is beneficial to the long-term storage of the wine and improves the flavor of the wine during long-term storage. By providing an accommodating cavity 34 in the plunger portion 30a of the cork 300 to fix the cork piece 500, the wine bottle 1000 can be opened by directly pulling out the cork 300 or unscrewing the cork 300, without the need to use tools to pull out the cork 300, which is conducive to improving the opening convenience of the wine bottle 1000; and after the cork 300 is pulled out, the fixing effect of the plunger portion 30a can keep the shape of the cork piece 500 unchanged, effectively avoiding the expansion and damage of the cork piece 500, ensuring that the overall structure of the cork 300 maintains its original shape after the wine bottle 1000 is opened, so that the cork 300 can be again covered on the bottle body 100 after the wine bottle 1000 is opened to block the sealing hole 13 to achieve closed storage of the wine bottle 1000, thereby ensuring the storage effect of the wine bottle 1000 on the wine liquid and improving the practicality and structural reliability of the wine bottle 1000.

[0040] 3 and 4 , in one embodiment of the present application, the plunger portion 30a includes a plunger barrel 31 and a fixed column 32. The outer circumference of the plunger barrel 31 abuts the inner wall of the sealing hole 13. The fixed column 32 is connected to the plunger barrel 31 and disposed within the plunger barrel 31. The outer wall of the fixed column 32 and the inner wall of the plunger barrel 31 enclose a receiving cavity 34 and a contact port 341. The end of the fixed column 32 facing away from the bottle body 100 is provided with an air flow hole 325. The wooden plug 500 is sleeved on the outer circumference of the fixed column 32 and abuts the inner wall of the plunger barrel 31. A balancing cavity 327 is provided within the fixed column 32. The fixed column 32 is also provided with an air inlet hole 35 that connects the balancing cavity 327 with the liquid storage cavity 11.

[0041] In this embodiment, the plunger portion 30a may include a plunger barrel 31 and a fixed column 32. By placing the fixed column 32 in the plunger barrel 31 and connecting the fixed column 32 to the inner wall of the plunger barrel 31, the outer wall of the fixed column 32 and the inner wall of the plunger barrel 31 can be used to enclose a receiving cavity 34 and a contact port 341. At this time, an air flow hole 325 can be provided at the portion where the fixed column 32 connects the plunger barrel 31, thereby allowing the air flow hole 325, the receiving cavity 34 and the contact port 341 to remain in the same straight line. At this time, the cork 500 can be provided in a cylindrical structure, and the cork 500 can be sleeved on the outer peripheral side of the fixed column 32 and abutted against the inner wall of the plunger barrel 31, so that the fixed column 32 and the plunger barrel 31 can clamp and fix the cork 500 to prevent the cork 500 from falling, thereby further improving the structural stability and reliability of the bottle stopper 300.

[0042] In existing wine bottles 1000, a certain amount of hollow space is typically reserved when storing wine. This allows the wine bottle 1000 to store gases generated by wine fermentation, facilitating long-term storage of the wine. In this embodiment, however, a balancing chamber 327 is provided within the fixed column 32, and an air inlet 35 is provided at the end of the fixed column 32 facing the bottle body 100, connecting the balancing chamber 327 with the liquid storage chamber 11. This allows gases generated by wine fermentation within the liquid storage chamber 11 of the wine bottle 1000 to be stored within the balancing chamber 327. This helps reduce the number of hollow spaces within the bottle body 100, allowing the wine to more effectively fill the bottle 1000. This further reduces redundant space within the wine bottle 1000 and facilitates a lightweight design for the wine bottle 1000. It is also beneficial for the wine in the wine bottle 1000 to more conveniently contact the wetting cork 500 through the contact port 341, thereby ensuring the overall sealing effect of the cork 300 and further improving the practicality and reliability of the wine bottle 1000.

[0043] 3 and 4 , in one embodiment of the present application, a sealed cavity 351 is formed within the air inlet 35, and a magnetic structure 32c is provided within the fixed column 32. The magnetic structure 32c is disposed adjacent to the bottom wall of the sealed cavity 351. The plunger portion 30a is further provided with a sealing plug 33, which is movably disposed within the sealed cavity 351 and is magnetically attracted to the magnetic structure 32c.

[0044] In this embodiment, by providing a sealing cavity 351 in the air inlet 35, and by providing a sealing plug 33 in the sealing cavity 351, and by utilizing the sealing plug 33 to move in the sealing cavity 351, the sealing plug 33 can be made to block the air inlet 35, thereby further improving the sealing effect of the wine bottle 1000. Particularly, by providing a magnetic structure 32c in the fixed column 32, and utilizing the magnetic attraction between the magnetic structure 32c and the sealing plug 33, when a large amount of fermentation gas is not generated in the wine bottle 1000 in daily life, the mutual attraction force between the sealing plug 33 and the magnetic structure 32c can be utilized to enable the sealing plug 33 to block the air hole on the bottom wall of the sealing cavity 351 penetrated by the air inlet 35, thereby achieving the blockage of the air inlet 35 and maintaining the overall sealing effect of the wine bottle 1000. When more gas is generated in the wine bottle 1000, the increased air pressure in the liquid storage chamber 11 can cause the air flow to act on the sealing plug 33 through the air inlet hole 35, and then the air flow pushes the sealing plug 33 to move in the sealing chamber 351 to open the air inlet hole 35, so that the gas can enter the balance chamber 327 through the air inlet hole 35, avoiding the high air pressure in the bottle body 100 that makes it inconvenient to pull out the bottle plug 300, reducing the force of the air flow in the liquid storage chamber 11 on the bottle body 100, and further improving the structural stability and reliability of the wine bottle 1000.

[0045] Secondly, the interior of the sealing plug 33 can be configured as a sealed cavity, which provides the sealing plug 33 with a certain amount of buoyancy. When the wine in the liquid storage chamber 11 ferments or expands due to heat, it can enter the sealed chamber 351 through the air inlet 35. After the wine is injected into the sealed chamber 351, the sealing plug 33 is affected by the buoyancy of the wine and floats within the sealed chamber 351, allowing some of the wine to pass through the sealed chamber 351 and into the balancing chamber 327 through the air inlet 35. This reduces the force exerted by the wine expansion on the bottle body 100 and further improves the practicality and reliability of the wine bottle 1000. When the wine cools and contracts, it flows back into the liquid storage chamber 11. At this point, the buoyancy acting on the sealing plug 33 is reduced, allowing the magnetic structure 32c to magnetically attract the sealing plug 33 and move it back to the bottom wall of the sealed chamber 351, covering the air inlet 35 to achieve a seal, thus ensuring the overall sealing effect of the wine bottle 1000.

[0046] Further, referring to Figures 3 and 4, in one embodiment of the present application, a card groove is formed on the bottom wall of the sealing cavity 351, and the inner diameter of the card groove gradually decreases in the direction toward the bottle body 100. One end of the sealing plug 33 is inserted into the card groove, and the outer peripheral side of the end of the sealing plug 33 is arranged to cooperate with the inner wall of the card groove.

[0047] In this embodiment, a retaining groove is formed on the bottom wall of the sealing cavity 351, and the air inlet 35 can be provided through the bottom wall of the retaining groove. The retaining groove allows the sealing plug 33 to abut against the inner wall of the retaining groove when not exposed to air pressure or liquid fluid. This facilitates better positioning and securing of the sealing plug 33 by utilizing the retaining groove, preventing the sealing plug 33 from shifting within the sealing cavity 351, and further improving the sealing effect and reliability of the wine bottle 1000. The inner diameter of the retaining groove can gradually decrease toward the bottle body 100, and the outer circumference of the end of the sealing plug 33 can be aligned with the inner wall of the retaining groove. Furthermore, the tapered end of the sealing plug 33 can be engaged and secured with the inverted tapered retaining groove, effectively securing the sealing plug 33 by utilizing the retaining groove, preventing the sealing plug 33 from shifting, and further improving the structural stability and reliability of the wine bottle 1000.

[0048] Referring to Figures 2 to 4, in one embodiment of the present application, the fixed column 32 includes a first fixed section 32a and a second fixed section 32b. One end of the first fixed section 32a is provided with a first groove 3211, and the wooden plug 500 is sleeved around the outer circumference of the first fixed section 32a. The first fixed section 32a has a magnetic structure 32c disposed therein. The second fixed section 32b has a balancing chamber 327 disposed therein. One end of the second fixed section 32b is inserted into the first groove 3211, enclosing the first groove 3211 and forming a sealed chamber 351. An air inlet 35 is provided through the first fixed section 32a and connects to the balancing chamber 327 through the end of the second fixed section 32b disposed in the first groove 3211.

[0049] In this embodiment, the second fixing section 32b is inserted into the first groove 3211 of the first fixing section 32a to enclose a sealed cavity 351. The fixing column 32 can be formed into a first fixing section 32a and a second fixing section 32b that are separately provided. The use of the separately provided fixing column 32 facilitates the assembly of the bottle stopper 300, reduces the assembly burden on workers, further improves the processing efficiency of the bottle stopper 300, and enhances the practicality and reliability of the wine bottle 1000. Furthermore, by sleeve-fitting the cork member 500 onto the outer circumference of the first fixing section 32a, during the production and assembly of the bottle stopper 300, the cork member 500 can first be connected and fixed using the first fixing section 32a, and then the first fixing section 32a, to which the cork member 500 is fixed, is connected and fixed to the second fixing section 32b within the plunger barrel 31, thereby further improving the assembly efficiency of the wine bottle 1000.

[0050] 2 to 4 , in one embodiment of the present application, a limiting groove is formed on the outer circumference of the first fixing section 32 a , and a portion of the wooden plug 500 is disposed in the limiting groove and abuts against the inner wall of the limiting groove.

[0051] In this embodiment, by forming a limiting groove on the outer peripheral side of the first fixed section 32a, a portion of the cork piece 500 can be arranged in the limiting groove, and the cork piece 500 can be made to abut against the inner wall of the limiting groove. Then, under the fixed limiting action of the limiting groove, the cork piece 500 can be more stably and reliably mounted on the outer peripheral side of the first fixed section 32a, which is conducive to better preventing the cork piece 500 from slipping on the first fixed section 32a, and further improving the structural stability and reliability of the wine bottle 1000.

[0052] Further, referring to Figures 2 to 4, in one embodiment of the present application, the first fixing section 32a includes a fixing sleeve 321 and a stopper pin 323. A partition 3213 is provided within the fixing sleeve 321, dividing the inner cavity of the fixing sleeve 321 into a first groove 3211 and a second groove 3215. The wooden plug 500 is sleeved on the outer circumference of the fixing sleeve 321. One end of the stopper pin 323 is inserted into the second groove 3215, and the other end of the stopper pin 323 is provided with a stopper edge 3231, which abuts against the end surfaces of the fixing sleeve 321 and the wooden plug 500. The magnetic structure 32c is provided between the bottom wall of the second groove 3215 and the stopper pin 323. The air inlet 35 is sequentially provided through the stopper pin 323, the magnetic structure 32c, and the partition 3213.

[0053] In this embodiment, the first fixed section 32a may include a fixed sleeve 321 and a limiting pin 323. At this time, by protruding a partition 3213 on the inner wall of the fixed sleeve 321, the partition 3213 can be used to separate the inner cavity of the fixed sleeve 321 into a first groove 3211 and a second groove 3215, so that the second connecting section can be inserted into the first groove 3211, and the limiting pin 323 can be inserted into the second groove 3215, thereby realizing the overall segmented assembly of the fixed column 32, which is conducive to better improving the assembly convenience of the bottle stopper 300. Therefore, during the installation process, the sealing plug 33 can be first placed into the first groove 3211, and the second connecting section can be inserted into the first groove 3211 to enclose a sealing cavity 351; then the second connecting section can be connected to the plunger tube 31, and the cork piece 500 can be sleeved on the outer peripheral side of the fixed sleeve 321; then the limiting pin 323 is inserted into the second groove 3215 at the other end of the plunger tube 31, and a limiting edge 3231 is provided at one end of the limiting pin 323, so that the limiting edge 3231 can abut against the end face of the fixed sleeve 321 and the end face of the cork piece 500 when the limiting pin 323 is inserted into the second groove 3215, thereby realizing the assembly limit of the cork piece 500 on the plunger part 30a, further improving the assembly convenience and practicality of the wine bottle 1000, and ensuring the sealing effect of the wine bottle 1000.

[0054] 3 , in one embodiment of the present application, the outer circumference of the limiting latch 323 is threadedly connected to the inner wall of the second groove 3215 , and / or the outer circumference of the second fixing section 32b is threadedly connected to the inner wall of the first groove 3211 .

[0055] In this embodiment, by threadedly connecting the outer peripheral side of the limit pin 323 to the inner wall of the second groove 3215, the connection and fixation between the two can be achieved by directly twisting the limit pin 323 or the fixing sleeve 321, which is conducive to better improving the connection stability and reliability of the limit pin 323 and the fixing sleeve 321, and further improving the assembly convenience of the stopper 300.

[0056] Similarly, by threadedly connecting the outer peripheral side of the second fixed section 32b to the inner wall of the first groove 3211, the connection and fixation between the two can be achieved by directly twisting the second fixed section 32b or the fixed sleeve 321, which is conducive to better improving the connection stability and reliability between the second fixed section 32b and the fixed sleeve 321, and further improving the assembly convenience of the stopper 300.

[0057] 1 , 3 and 4 , in one embodiment of the present application, an exhaust hole 329 connected to the balancing chamber 327 is further provided at one end of the fixed column 32 facing away from the bottle body 100, and the bottle stopper 300 is further provided with a valve body structure 30c, which is connected to the end of the fixed column 32 facing away from the bottle body 100 and covers the exhaust hole 329.

[0058] In this embodiment, a vent 329 communicating with the balancing chamber 327 is provided at the opposite end of the fixed column 32, and a valve structure 30c is provided on the end surface of the fixed column 32 to cover the vent 329. This valve structure 30c can be a one-way valve structure, allowing gas within the wine bottle 1000 to escape from the bottle while preventing air from outside the bottle from entering the vent 329. When the air pressure within the liquid storage chamber 11 is higher than the air pressure outside the bottle, the airflow within the liquid storage chamber 11, after filling the balancing chamber 327, can act on the valve structure 30c through the vent 329. Furthermore, when the air pressure within the wine bottle 1000 exceeds a certain threshold, the valve structure 30c can be pushed open to vent air. This prevents prolonged fermentation in the wine bottle 1000 from generating excessive gas and increasing the internal pressure of the wine bottle 1000, ensuring that the wine bottle 1000 can be opened more conveniently. When the air pressure in the liquid storage chamber 11 is equal to or lower than the external air pressure, the valve body structure 30c can be subjected to less force and the exhaust hole 329 can be re-covered, thereby ensuring the sealing effect of the bottle stopper 300 and further improving the structural stability and reliability of the wine bottle 1000.

[0059] 1 and 3 , in one embodiment of the present application, the valve body structure 30 c is provided with a spring piece 37 , which is connected to the end face of the fixed column 32 and covers the exhaust hole 329 , and a sealing protrusion 38 is provided on the surface of the spring piece 37 facing the fixed column 32 , and the sealing protrusion 38 is movably inserted into the exhaust hole 329 .

[0060] In this embodiment, the valve body structure 30c may include a spring plate 37, which may be connected to a mounting structure on the surface of the fixed column 32. By providing a sealing protrusion 38 on the spring plate 37 and inserting it into the vent 329, the spring plate 37 can maintain a certain elasticity during normal storage, pressing the sealing protrusion 38 against the vent 329, thereby ensuring the overall sealing performance of the wine bottle 1000. When the air pressure within the wine bottle 1000 increases, the high-pressure airflow acts on the sealing protrusion 38 and the spring plate 37, thereby pushing the sealing protrusion 38 away from the bottle body 100 and pressing the spring plate 37, causing the spring plate 37 to elastically deform. This allows the gas within the vent 329 to be discharged through the gap between the spring plate 37 and the end surface of the fixed body, thereby venting the wine bottle 1000. After the exhaust is completed, the spring 37 can restore its elastic deformation to drive the sealing protrusion 38 to be inserted into the exhaust hole 329 again to seal the exhaust hole 329, further improving the sealing reliability and stability of the wine bottle 1000.

[0061] 3 and 4 , in one embodiment of the present application, a limiting protrusion 311 is provided on the inner wall of the plunger tube 31, and the limiting protrusion 311 abuts against the end surface of the wooden plug 500. Alternatively, a notch is provided on the outer circumference of the plunger tube to communicate with the accommodating cavity, and the wooden plug partially blocks the notch.

[0062] In this embodiment, by providing a limiting protrusion 311 on the inner wall of the plunger barrel 31, the limiting protrusion 311 can better abut the end surface of the cork 500 under the action of the limiting protrusion 311, so that the limiting protrusion 311 can play a certain role in limiting and fixing the cork 500, thereby more stably positioning the cork 500 in the accommodating cavity 34, effectively preventing the cork 500 from sliding and deflecting in the accommodating cavity 34, better ensuring the sealing effect of the bottle stopper 300, and further improving the structural reliability and practicality of the wine bottle 1000. The limiting protrusion 311 can be formed as an integral structure with the plunger barrel 31, or the limiting protrusion 311 can be a limiting retaining ring that is interference-fitted on the inner wall of the plunger barrel 31, which can also play a certain role in abutting the fiber cork 500, thereby improving the practicality and reliability of the wine bottle 1000.

[0063] Secondly, a notch connecting to the accommodating chamber 34 can be opened on the outer peripheral side of the plunger tube 31. When the cork piece 500 is set in the accommodating chamber 34, the cork piece 500 can be abutted against the inner wall of the plunger tube 31 and part of the cork piece 500 can be squeezed out on the notch to block the notch. Then, when the wine bottle 1000 is sealed with wine or the wine bottle 1000 containing wine is transported, part of the wine can wet the cork piece 500, so that the cork piece 500 expands after absorbing a small amount of wine, so that part of the cork piece 500 can expand and be squeezed out on the outer peripheral side of the plunger tube 31 through the notch, so that part of the cork piece 500 can abut against the inner wall of the sealing hole 13 through the notch after expansion, thereby further utilizing the part of the cork piece 500 protruding from the outer peripheral side of the plunger tube 31 to improve the contact sealing effect between the bottle stopper 300 and the bottle body 100, further improve the sealing performance of the wine bottle 1000, and improve the structural stability and reliability of the wine bottle 1000. The notch provided on the outside of the plunger tube 31 is mostly small in size, and the part of the cork piece 500 protruding from the notch on the outer peripheral side of the plunger tube 31 is also small, so that when the cork 300 is pulled out of the bottle body 100 and reinserted into the bottle body 100 for sealing, the part of the cork piece 500 protruding from the outer peripheral side of the plunger tube 31 can be cut off, or the part of the cork piece 500 protruding from the notch can be pressed under the action of external force to make it inserted into the accommodating cavity 34 to avoid the plunger part 30a from being inserted into the sealing hole 13, so that the cork 300 can be reinserted into the bottle body 100 more stably, ensuring that the wine bottle 1000 is sealed for a long time after being opened.

[0064] 1 to 4 , in one embodiment of the present application, the bottle stopper 300 is further provided with a screw-on capping cylinder 30 b , the plunger portion 30 a is connected to the screw-on capping cylinder 30 b and is disposed inside the screw-on capping cylinder 30 b , and the inner wall of the screw-on capping cylinder 30 b is threadedly connected to the outer peripheral side of the bottle body 100 .

[0065] In this embodiment, the bottle stopper 300 may also be provided with a screw-on capping cylinder 30b. By disposing the plunger portion 30a in the screw-on capping cylinder 30b and connecting the plunger portion 30a to the inner wall of the screw-on capping cylinder 30b, the bottle stopper 300 can be connected to the bottle body 100 using a screw threaded connection, thereby achieving the opening and sealing closure of the wine bottle 1000. The bottle stopper 300 can then be opened by unscrewing the bottle stopper 300, which can help to better improve the operability of the wine bottle 1000 and further enhance the practicality and reliability of the wine bottle 1000. The inner wall of the screw-on capping cylinder 30b can abut against the outer circumference of the bottle body 100. The screw-on capping cylinder 30b and the plunger portion 30a can respectively abut against the outer wall and inner wall of the end of the bottle body 100, so that the bottle stopper 300 can more stably clamp and fix the end of the bottle body 100, achieving a better sealed storage effect, and further enhancing the structural stability and reliability of the wine bottle 1000.

[0066] 2 , 3 and 5 , in one embodiment of the present application, the bottle body 100 includes a bottle body section 10a, a bottleneck section 10b and a threaded sleeve 10c. The bottle body section 10a is provided with a liquid storage chamber 11; the bottleneck section 10b is connected to the bottle body section 10a, and a sealing hole 13 is provided in the bottleneck section 10b; the threaded sleeve 10c is sleeved on the outer peripheral side of the bottleneck section 10b, and a threaded structure 15 is provided on the surface of the threaded sleeve 10c facing away from the bottleneck section 10b, and the inner wall of the screw cap cylinder 30b is threadedly connected to the threaded structure 15.

[0067] In this embodiment, a threaded sleeve 10c is sleeved on the neck section 10b of the bottle body 100, and the threaded structure 15 on the outer periphery of the threaded sleeve 10c is threadedly connected to the inner wall of the screw cap cylinder 30b to achieve the connection and fixation between the bottle stopper 300 and the bottle body 100. The threaded sleeve 10c can better protect the structure of the bottle body 100, preventing the bottle body 100 and the stopper 300 from being directly threadedly connected. Damage to the appearance of the bottle body 100 is thus improved, thereby enhancing the aesthetics of the wine bottle 1000. Furthermore, by sleeved on the neck section 10b of the bottle body, the wine bottle 1000 can be recycled, and the threaded sleeve 10c can be fixed and assembled using the existing structure on the neck of the bottle body 100, which is conducive to further reducing the production cost of the wine bottle 1000 and further improving the practicality of the wine bottle 1000.

[0068] 3 and 4 , in one embodiment of the present application, a sealing gasket 36 is provided between the inner wall of the screw-capping cylinder 30 b and the outer wall of the plunger portion 30 a , and the sealing gasket 36 is used to abut against the end of the bottle body 100 .

[0069] In this embodiment, by arranging a sealing gasket 36 between the inner wall of the screw-on cap cylinder 30b and the outer wall of the plunger portion 30a, when the bottle stopper 300 covers the bottle body 100, the end of the bottle body 100 can be passed through the screw-on cap cylinder 30b and the plunger portion 30a and can directly abut against the sealing gasket 36, and then the sealing gasket 36 can be used to surround the end face of the bottle body 100, which is conducive to better utilizing the sealing gasket 36 to block the gap between the bottle stopper 300 and the bottle body 100, thereby achieving a better sealing effect of the wine bottle 1000 and further improving the practicality and structural reliability of the wine bottle 1000. Among them, if the plunger part 30a is connected to the inner wall of the screw-on cap cylinder 30b, the sealing gasket 36 can be connected and fixed to the part of the plunger part 30a connected to the stopper cylinder, and then when the plunger part 30a is inserted into the sealing hole 13, the sealing gasket 36 can be made to abut the end face of the sealed bottle body 100, which is conducive to better utilizing the sealing effect of the plunger part 30a and the sealing gasket 36 to further improve the sealing reliability and stability of the wine bottle 1000.

[0070] 5 , in one embodiment of the present application, the bottle body 100 is defined as having a height direction, and the inner diameter of the sealing hole 13 gradually decreases from top to bottom along the height direction.

[0071] In this embodiment, by gradually reducing the inner diameter of the sealing hole 13 from top to bottom along the height direction, the sealing hole 13 can be configured to be wider at the top and narrower at the bottom. Consequently, when the bottle stopper 300 is moved onto the bottle body 100 to cover the sealing hole 13, the wider bottle mouth of the sealing hole 13 can be utilized to facilitate insertion of the plunger portion 30a of the bottle stopper 300 into the sealing hole 13. As the plunger portion 30a is inserted deeper into the sealing hole 13, it gradually abuts against the inner wall of the lower portion of the sealing hole 13, thereby blocking and sealing the gap between the plunger portion 30a and the sealing hole 13, thereby ensuring a sealed effect for the wine bottle 1000. By varying the inner diameter of the sealing hole 13 along the height direction, the assembly convenience of the wine bottle 1000 can be improved while also ensuring better assembly reliability and stability of the wine bottle 1000. Among them, the outer peripheral side of the plunger part 30a can be set in coordination with the inner wall of the sealing hole 13, so that the outer peripheral side of the plunger part 30a is also set at an angle, and then the outer peripheral side of the plunger part 30a and the inner wall of the sealing hole 13 are matched with each other, which is conducive to further increasing the contact area between the plunger part 30a and the sealing hole 13, and improving the connection stability and reliability of the bottle body 100 and the bottle stopper 300.
