Description

Technical Field

[0001] The present invention belongs to the technical field of liquid storage equipment, and in particular relates to a storage device. Background Art

[0002] Commonly used storage containers for storing liquids such as red wine, beverages, and oils are mostly simple containers, such as glass bottles. After a portion of the liquid is poured out of the container, air will enter the container, and the remaining liquid in the container is prone to oxidation. For example, after the common red wine bottle is opened, the red wine is easily oxidized and deteriorated by contact with oxygen in the air. When there is still some red wine left in the red wine bottle, it is easy to be oxidized by the air in the bottle, and the shelf life is short. When drinking it again, the taste is quite different.

[0003] If opened wine needs to be stored for a longer period of time, it is still necessary to minimize the oxidation reaction between the wine and oxygen in the air. The traditional storage methods are:

[0004] Refrigeration: It does not isolate the air and has no actual obvious effect in slowing down oxidation. The main function of a wine cabinet is to store unopened bottles of wine. If it is placed in a refrigerator, the excessively low temperature will cause obvious damage to the taste quality of the red wine.

[0005] Refilling the bottle with a smaller one after opening it is troublesome, and the volume of the small bottle is fixed, so it is impossible to adjust the size according to the amount of remaining wine.

[0006] Vacuum stopper: Since the volume of the wine bottle is fixed, its size cannot be adjusted as air is extracted. There is still a large amount of air in the bottle, and there is no obvious effect in preventing oxidation.

[0007] Filling the wine bottle with inert gas: The operation is cumbersome and requires very expensive professional machines and expensive inert gas consumables. The method of injecting inert gas after opening the bottle cannot completely isolate oxygen, but only reduces the oxygen content in the bottle and the amount of oxygen contact with the wine. In addition, the machine equipment is large in size and the inert gas consumables are expensive, so it does not have the value of large-scale promotion. Another method of injecting inert gas without opening the bottle requires the use of original wood corks, while most wines on the market do not use original wood corks. Its scope of use cannot cover most commercially available wines, but the equipment is expensive, the consumables are large and the cost is high, and the operation is cumbersome.

[0008] The above methods and devices have the problems of poor effect in preventing oxidation of wine after opening, high cost of equipment and consumables, complicated operation and inconvenient use. Summary of the invention

[0009] The purpose of the present invention is to provide a storage device, aiming to solve the technical problems of poor anti-oxidation effect, complicated operation and inconvenient use of storage devices in the prior art.

When the plug rotates along the predetermined direction, the driving rod can be driven to rotate, and when the driving rod rotates, the float can be driven to rise relative to the air duct. When the plug is removed from the air duct, the liquid in the container can flow out from the gap between the float and the sealing ring, and then when the container is dumped, the liquid in the container can be poured out through the air duct.

[0017] Furthermore, the inner wall of the groove is provided with a plurality of convex strips at intervals in an annular direction, and protrusions are respectively provided on two opposite sides of the outer peripheral wall of the top end of the driving rod, and the convex strips and the protrusions form the locking structure; the air guide tube is embedded with a fixed sleeve, the driving rod passes through the fixed sleeve, and limiting grooves are respectively provided on two opposite sides of the inner wall of the fixed sleeve, the upper section of the protrusion extends into the groove, and the lower section of the protrusion extends into the limiting groove; an inclined surface is formed in the limiting groove, and when the driving rod rises to the unlocking position, the lower section of the protrusion abuts against the inclined surface, and when the plug rotates along the predetermined direction, the convex strip abuts against the protrusion to drive the driving rod to rotate, and when the driving rod rotates, the lower sections of the protrusions on both sides rise along the corresponding inclined surfaces respectively, thereby causing the driving rod to rise relative to the air guide tube, thereby achieving further close contact between the outer peripheral side wall of the float and the sealing ring.

[0018] Furthermore, the fixed sleeve includes an outer sleeve and an inner sleeve arranged coaxially, the limiting grooves are respectively provided on the opposite sides of the inner wall of the inner sleeve, the inner sleeve is arranged in the outer sleeve and connected to the outer sleeve through a plurality of connecting ribs spaced from each other, the driving rod passes through the inner sleeve, and the inclined surface is a plane or an arc surface.

[0019] Furthermore, the inner wall of the inner sleeve forms a step, and the outer peripheral wall of the driving rod protrudes from one end close to the protrusion to form a retaining ring to limit the driving rod from moving downward relative to the air guide tube.

[0020] Furthermore, a threaded connection structure is formed between the float and the driving rod, and the bottom end of the driving rod is connected to the top end of the float through the threaded connection structure.

[0021] Furthermore, the top end of the container is open and is threadedly connected to a lid, the lid is provided with a through hole, the air duct includes an upper air duct and a lower air duct connected together by threads, the upper air duct passes through the through hole and extends out of the container, and one end of the sealing ring is sleeved on the outer peripheral wall of the lower air duct.

[0022] Furthermore, the upper air duct is formed with a first gradually widening section near the opening of the container, and the diameter of the first gradually widening section gradually increases from bottom to top; the bottom end of the lower air duct is formed with a second gradually widening section, and the diameter of the second gradually widening section gradually increases from top to bottom; the outer peripheral wall of the plug is circumferentially provided with a plurality of protrusions at intervals corresponding to the area of ​​the first gradually widening section, and the sealing ring is engaged with the bottom end of the second gradually widening section.

[0023] Furthermore, the bottom surface of the float is a spherical surface that curves downward, and the outer peripheral side wall of the float includes a first surface, a second surface, and a third surface that are connected in sequence from bottom to top, the first surface is connected to the bottom surface of the float, the second surface is arranged horizontally, and the top ends of the first surface and the third surface are both inclined toward the inner side of the float; a sealing portion is formed annularly at the bottom end of the sealing ring, and the top end of the sealing portion is inclined toward the central axis direction of the container, the outer wall of the sealing portion is tightly attached to the inner surface of the container, and the inner wall contour of the sealing portion is in contact with the second surface when the float rises.

[0024] Beneficial effects of the present invention: In the storage device of the present invention, when the air guide tube drives the piston to move downward relative to the container, a gap is formed between the sealing ring and the float, and the gas can flow into the air guide tube through the gap and be discharged from the top opening of the air guide tube. The float moves until it contacts the liquid surface until the exhaust is completed, and the float rises, and the gap between the float and the outer sealing ring gradually decreases. After the exhaust is completed, the float and the sealing ring are initially in close contact. Since the plug and the float are linked, the plug is inserted into the air guide tube. When the plug rotates in a predetermined direction, it can drive the float to rise, so that the float and the sealing ring can be further in close contact, so that the liquid in the container is isolated from the air, and the outside air is not easy to enter the container from between the sealing ring and the float, which slows down the liquid deterioration process, can achieve a better anti-oxidation effect, and has a long preservation time.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] like Figures 1 to 3 and Figure 5 As shown, the storage device provided by the embodiment of the present invention includes a container 10, an adjusting member 20 and a stopper 30. The container 10 can be made of a transparent or translucent material, and the top of the container 10 is open; the top of the container 10 can be provided with a cover 100, and the cover 100 can be detachably mounted on the container 10. The cover 100 is provided with a through hole, and the through hole is coaxially arranged with the container 10. When the cover 100 is removed and the adjusting member 20 is taken out, the liquid contained in the container 10 can be poured out, and the components in the container 10 can be cleaned.

[0045] like Figure 3 , Figure 5As shown, the regulating member 20 includes an air guide tube 21 and a piston 22. The upper and lower ends of the air guide tube 21 are open. The piston 22 is connected to the bottom end of the air guide tube 21. The top end of the air guide tube 21 passes through the through hole of the cover 100. The air guide tube 21 can drive the piston 22 to move up and down relative to the container 10. The piston 22 includes a float 230 connected to the air guide tube 21 and a sealing ring 220 sleeved on the outer periphery of the float 230. The float 230 and the sealing ring 220 are both made of food grade materials. When the air guide tube 21 moves up and down relative to the container 10, the sealing ring 220 is in close contact with the inner surface of the container 10. When the air guide tube 21 drives the piston 22 to move downward relative to the container 10, a gap is formed between the sealing ring 220 and the float 230, so that the gas can flow into the air guide tube 21 through the gap and be discharged from the top opening of the air guide tube 21.

[0046] When the float 230 moves to the point where the bottom surface of the float 230 is in full contact with the liquid, the outer peripheral side wall of the float 230 is in close contact with the sealing ring 220; the plug 30 and the float 230 are linked, and the plug 30 can drive the float 230 to rise when rotating in a predetermined direction. When the float 230 moves downward until it can no longer move downward, the exhaust is completed. At this time, the plug 30 is inserted into the opening at the top of the air guide tube 21. When the plug 30 is rotated in a predetermined direction, the float 230 is driven by the plug 30 to rise a certain distance. At this time, the float 230 is further in close contact with the sealing ring 220, thereby closing the gap between the sealing ring 220 and the float 230, so that the outside air is not easy to enter the container 10 from the air guide tube 21 and contact the liquid. The sealing effect is good, which can enhance the anti-oxidation function of the storage device and extend the preservation time.

[0047] In the storage device provided by the present embodiment, when the air guide tube 21 drives the piston 22 to move downward relative to the container 10, a gap is formed between the sealing ring 220 and the float 230, and the gas can flow into the air guide tube 21 through the gap and be discharged from the top opening of the air guide tube 21. The float 230 moves to contact the liquid surface until the float 230 rises when the exhaust is completed, and the gap between the float 230 and the outer sealing ring 220 gradually decreases. After the exhaust is completed, the float 230 and the sealing ring 220 are initially in close contact. Since the plug 30 and the float 230 are linked, the plug 30 is inserted into the air guide tube 21. When the plug 30 rotates in a predetermined direction, it can drive the float 230 to rise, so that the float 230 and the sealing ring 220 can be further in close contact, so that the liquid in the container 10 is isolated from the air, and the outside air is not easy to enter the container 10 from between the sealing ring 220 and the float 230, which slows down the liquid deterioration process, can achieve a better anti-oxidation effect, and has a long preservation time.

[0048] In one embodiment, if Figure 3 , Figure 5As shown, the top of the float 230 is connected to a driving rod 240, and the driving rod 240 is received in the air guide tube 21. The plug 30 forms a linkage structure with the float 230 through the driving rod 240. The plug 30 moves in a predetermined direction (such as Figure 5 , Figure 8 When the stopper 30 rotates (in the F1 direction), the driving rod 240 can be driven to rotate, and when the driving rod 240 is driven by the stopper 30 to rotate, the float 230 can be driven to rise relative to the air guide tube 21. When the stopper 30 is removed from the air guide tube 21, the liquid in the container 10 can flow out from the gap between the float 230 and the sealing ring 220, and then when the container 10 is tipped, the liquid in the container 10 can be poured out through the air guide tube 21. When performing exhaust operation, the plug 30 can be pulled out and force can be applied to the air pipe 21, so that the air pipe 21 drives the piston 20 to move downward. When the float 230 drops to contact with the liquid surface and the gas is exhausted, the float 230 cannot drop further. At this time, the plug 30 is inserted into the air pipe 21, and the plug 30 is rotated a certain angle in a predetermined direction. The plug 30 lifts the float 230 through the driving rod 240, so that the float 230 rises at the same time, thereby making the outer peripheral side wall of the float 230 and the sealing ring 220 more closely attached. When it is necessary to pour out the liquid in the container 10, the plug 30 is rotated in a direction opposite to the predetermined direction to drive the driving rod 240 to the unlocking position, causing the driving rod 240 to move slightly downward relative to the air guide tube 21, and driving the float 230 to move slightly downward, and the plug 30 is pulled out to release the further close contact between the float 230 and the sealing ring 220, and then the air guide tube 21 is moved upward by external force, driving the driving rod 240 and the float 230 to move upward, and the float 230 and the driving rod 240 drop due to their own gravity, and a gap is formed between the outer peripheral side wall of the float 230 and the sealing ring 220, so that the container 10 is tilted, and the liquid in the container 10 can flow out along the inner wall of the air guide tube 21.

[0049] In one embodiment, if Figure 3 , Figure 7As shown, the bottom surface of the stopper 30 is concave to form a groove 310, and a locking structure is formed between the groove wall of the groove 310 and the driving rod 240. When the air guide tube 21 drives the piston to move downward and the float 230 does not contact the liquid in the container 10, the driving rod 240 and the float 230 are in a free suspension state. At this time, there is a gap between the outer peripheral side wall of the float 230 and the sealing ring 220. During the downward movement of the air guide tube 21, the gas can flow out from the gap and then be discharged through the air guide tube 21. When the float 230 moves and contacts the liquid in the container 10 until the exhaust is completed, the float 230 rises to a predetermined height due to the buoyancy of the liquid. At this time, the driving rod 240 rises to the unlocking position and the top of the driving rod 240 extends into the groove 310, so that when the stopper 30 rotates in a predetermined direction, the driving rod 240 can be driven to rise relative to the air guide tube 21 through the locking structure, thereby making the outer peripheral side wall of the float 230 and the sealing ring 220 more closely attached. That is to say, in this process, the float 230 has two rising actions, the first is the exhaust gas rising due to the buoyancy of the liquid, and the second is the plug 30 driving the driving rod 240 to rise relative to the air guide tube 21 when rotating with the help of the locking structure, so that the float 230 rises again by a certain distance, so that the float 230 and the sealing ring 220 can be more closely attached, and the storage device has a better preservation effect. The cross-sections of the driving rod 240 and the groove 310 can be set to be circular.

[0050] In one embodiment, if Figure 3 , Figure 7 As shown, the inner side wall of the groove 310 is provided with a plurality of convex strips 320 at intervals in an annular direction, and the outer peripheral wall of the top of the driving rod 240 is provided with protrusions 241 on both sides opposite to each other. The diameter of the groove 310 is greater than the distance between the outermost sides of the two protrusions 241, and the convex strips 320 and the protrusions 241 form a locking structure. Figure 7 , Figure 8 As shown, the air guide tube 21 is embedded with a fixed sleeve 250 , and the driving rod 240 passes through the fixed sleeve 250 . The fixed sleeve 250 has limiting grooves 256 on opposite sides of the inner wall. The upper section of the protrusion 241 extends into the groove 310 , and the lower section of the protrusion 241 extends into the limiting groove 256 .

[0051] An inclined surface 257 is formed in the limiting groove 256, and the protrusion 241 abuts against the inclined surface 257. After the exhaust is completed, the driving rod 240 rises to the unlocking position. At this time, the lower section of the protrusion 241 abuts against the inclined surface 257. When the plug 30 rotates in a predetermined direction, the convex strip 320 abuts against the protrusion 241. In this way, the rotation of the plug 30 can drive the driving rod 240 to rotate. During this rotation process of the driving rod 240, the lower sections of the protrusions 241 on both sides rise along the corresponding inclined surfaces 257 respectively, so that the driving rod 240 can rise relative to the air guide tube 21, thereby achieving further close contact between the outer peripheral side wall of the float 230 and the sealing ring 220. The inclined directions of the inclined surfaces 257 in the two limiting grooves 256 are opposite, so that when the driving rod 240 is in the unlocking position, the protrusions 241 on both sides can slide smoothly in the corresponding limiting grooves 256. The cooperation among the convex strip 320, the protrusion 241, the limiting groove 256 and the inclined surface 257 enables the plug 30 and the driving rod 240 to form a linkage, but the plug 30 and the driving rod 240 are not connected together, and both are a rotational adjustment structure.

[0052] In one embodiment, if Figure 8 , Fig. 9 As shown, the fixing sleeve 250 includes an outer sleeve 251 and an inner sleeve 252 arranged coaxially. The inner sleeve 252 is arranged in the outer sleeve 251 and connected to the outer sleeve 251 through a plurality of connecting ribs 253 spaced apart from each other. The inner diameter of the inner sleeve 252 is larger than the outer diameter of the driving rod 240. The driving rod 240 passes through the inner sleeve 252. The inner sleeve 252 has two opposite sides of the inner wall provided with limiting grooves 256. The inclined surface 257 of the limiting groove 256 can be a plane or an arc surface. The inclination angle and length of the inclined surface 257 can be set according to actual application requirements. In one embodiment, as Figure 8 As shown, two symmetrical connecting ribs 253 are provided between the inner sleeve 252 and the outer sleeve 251, and a limiting groove 256 is provided on the inner wall of the inner sleeve 252; there is a gap between the outer sleeve 251 and the bottom surface of the plug 30, a part of the top of the inner sleeve 252 extends out of the outer sleeve 251, and there is also a gap between the inner sleeve 252 and the bottom surface of the plug 30, and the outer sleeve 251, the inner sleeve 252 and the groove 310 on the bottom surface of the plug 30 are coaxially arranged.

[0053] In one embodiment, the number of the ridges 320 of the groove 310 of the plug 30 can be set to 2, 4 or 6. Figure 3 , Figure 7As shown, four convex strips 320 are evenly spaced circumferentially arranged on the inner wall of the groove 310, so that after the container 10 is exhausted, the plug 30 is inserted into the air guide tube 21, and the operation of rotating the plug 30 to make the float 230 rise is more reasonable. After the plug 30 is inserted into the air guide tube 21, no matter whether the position of each convex strip 320 is close or far relative to the protrusion 241, the plug 30 only needs to rotate a small angle to drive the driving rod 240 to start rotating, which can be convenient to use.

[0054] In one embodiment, if Figures 7 to 9 As shown, the inner wall of the inner sleeve 252 forms a step 258, and the outer peripheral wall of the driving rod 240 protrudes to form a stop ring 242 at one end close to the protrusion 241 to limit the driving rod 240 from moving downward relative to the air guide tube 21. In other words, when the driving rod 240 is at the initial position (not rising), the bottom surface of the stop ring 242 abuts against the step 258, so that the driving rod 240 will not fall downward along the inner sleeve 252.

[0055] In one embodiment, the driving rod 240 and the float 230 are detachably connected, and the two can be detachably assembled by buckling, threading or other methods. In one embodiment, a threaded connection structure is formed between the float 230 and the driving rod 240, and the bottom end of the driving rod 240 is connected to the top end of the float 230 through the threaded connection structure, that is, the float 230 and the driving rod 240 are screwed. Figure 5 , Figure 6 As shown, a hollow extension section 234 is vertically arranged at the central position of the top surface of the float 230, and the driving rod 240 is screwed to the extension section 234, thereby realizing detachable assembly with the float 230; the top end of the extension section 234 is open, and the inner peripheral wall of the top end is provided with an internal thread, and the outer peripheral wall of the bottom end of the driving rod 240 is provided with a matching external thread, and the driving rod 240 extends into the top end of the extension section 234, and the screw connection is realized by the thread matching of the internal thread and the external thread.

[0056] In one embodiment, if Figure 3 , Figure 5As shown, the air duct 21 includes an upper air duct 210 and a lower air duct 211 that are detachably connected. In one embodiment, the top of the container 10 is threadedly connected with a lid 100, and the lid 100 is provided with a through hole. The air duct 21 includes an upper air duct 210 and a lower air duct 211 that are threadedly connected together. The upper air duct 210 passes through the through hole and extends out of the container 10, and one end of the sealing ring 220 is sleeved on the outer peripheral wall of the lower air duct 211; the top of the lower air duct 211 is embedded with a fixed ring 214, and the inner peripheral wall of the fixed ring 214 is provided with an internal thread, and the outer peripheral wall of the bottom end of the upper air duct 210 is provided with an adapted external thread, and the external thread of the upper air duct 210 is threadedly matched with the internal thread of the fixed ring 214, so that the components are easy to process, and the upper air duct 210 and the lower air duct 211 are easy to assemble, and the disassembly and assembly operations between the two are very convenient, and they are also convenient for cleaning and disinfection operations.

[0057] In one embodiment, if Figure 3 , Figure 5 As shown, the upper air duct 210 is formed with a first gradually widening section 212 near the opening of the container 10, and the diameter of the first gradually widening section 212 gradually increases from bottom to top. The bottom end of the lower air duct 211 is formed with a second gradually widening section 213, and the diameter of the second gradually widening section 213 gradually increases from top to bottom.

[0058] like Figure 3 , Figure 5 and Figure 7 As shown, the plug 30 includes a coaxially arranged head 31 and a rod 32, a groove is formed at the central position of the bottom surface of the rod 32, and an outer circumferential side wall of the rod 32 protrudes at one end close to the head 31 to form a shoulder 33, the top surface of the shoulder 33 is connected to the bottom surface of the head 31, and the bottom surface of the shoulder 33 is an annular inclined surface, the inclination angle of the annular inclined surface is adapted to the inclination angle of the first gradually widening section 212, and a plurality of protrusions 330 are circumferentially evenly spaced on the annular inclined surface. When the plug 30 is inserted into the upper air duct 210, the rod 32 is accommodated in the upper air duct 210, and there is a gap between the head 31 and the upper air duct 210, and each protrusion 330 is respectively in contact with the inner surface of the first gradually widening section 212.

[0059] In one embodiment, if Figure 3 As shown, the bottom surface of the float 230 is a spherical surface that curves downward, and the radius and curvature of the spherical surface can be set according to the inner diameter of the container 10. In this way, when the float 230 moves to contact the liquid in the container 10, the bottom surface of the float 230 can better match the shape of the liquid surface, and the gas near the peripheral side is easier to discharge when the float 230 moves downward.

[0060] like Figures 10-12As shown, the outer peripheral side wall of the float 230 includes a first surface 231, a second surface 232 and a third surface 233 which are sequentially connected from bottom to top, the first surface 231 is connected to the bottom surface of the float 230, the second surface 232 is arranged horizontally, and the top ends of the first surface 231 and the third surface 233 are both inclined toward the inner side of the float 230. In this way, the outer peripheral side wall of the float 230 forms a zigzag surface. The setting of the zigzag surface is conducive to not leaving liquid at this position after the liquid is poured in, so that the liquid can flow into the container 10. The bottom end of the sealing ring 220 is circumferentially formed with a sealing portion 222, the top end of the sealing portion 222 is inclined toward the central axis of the container 10, the outer wall of the sealing portion 222 is in close contact with the inner surface of the container 10, and the inner wall contour of the sealing portion 222 is consistent with the outer peripheral side wall contour of the float 230, so that after the exhaust is completed, the corresponding area of ​​the inner wall of the sealing portion 222 is in close contact with the second surface 232 of the float 230 during the further rise of the float 230. Fig.11 As shown, the inner wall of the sealing part 222 is in close contact with the second surface 232, and there is a gap between the inner wall of the sealing part 222 near the top and the third surface 233 to facilitate exhaust. The float 230 can be a hollow structure, and the top surface of the float 230 can be provided with an arc surface, and the extension section 234 is integrally formed at the central position of the arc surface, and the bottom end of the arc surface is connected to the third surface 233. The setting of the arc surface makes the upper part of the float 230 have a structure that is thick in the middle and thin on the sides, and the upper part of the float 230 forms a trumpet-like structure. The setting of the arc surface also facilitates the gas to flow out of the gap into the air guide pipe 21 more smoothly during exhaust.

[0061] like Figure 4 , Fig.11 and Fig.12 As shown, the sealing ring 220 also includes a connecting portion 221 integrally formed with the sealing portion 222, and there is a gap between the connecting portion 221 and the inner surface of the container 10, and the connecting portion 221 is used to engage with the lower air guide tube 211. The bottom end of the first gradually widened section 212 is provided with an extension portion 215, and the outer side wall of the extension portion 215 is formed with a first step surface extending horizontally and a second step surface extending vertically; the connecting portion 221 is formed with an annular retaining edge 223 extending toward the central axis of the container 10, and the bottom surface of the annular retaining edge 223 abuts against the first step surface, and the inner wall of the sealing ring 220 close to the annular retaining edge 223 is in close contact with the second step surface, and the inner wall of the connecting portion 221, the annular retaining edge 223 and the sealing portion 222 together form an annular groove 228 adapted to accommodate the extension portion 215, and the extension portion 215 is clamped in the annular groove 228.

[0062] like Figures 10-12As shown, the inner wall of the sealing portion 222 is formed with a first mating surface 225 and a second mating surface 226 near the bottom end; the inner wall of the sealing portion 222 is evenly spaced at annular intervals near the top end, such as 4 limiting portions 224, and the limiting portions 224 are formed with a third mating surface 227. When the float 230 is lifted by the buoyancy of the liquid and pressed against the sealing ring 220, the second mating surface 226 is in close contact with the second surface 232, and the third mating surface 227 is in close contact with the third surface 233. The setting of the limiting portion 224 enables a relatively stable mating structure to be formed between the sealing ring 220 and the air guide tube 21. For example, when the air guide tube 12 moves up and down relative to the container 10, the sealing ring 220 can be relatively stably clamped on the air guide tube 21 and move with the air guide tube 21.

[0063] In one embodiment, the outer surfaces of the cover 100, the air duct 21 and the plug 30 may be provided with a copper plating layer, which not only makes the storage device more beautiful as a whole, but also makes it difficult to see fingerprints and adhesions left by users after contact on the outer surfaces of these components.

[0064] The outer side wall of the container 10 may be provided with an anti-slip structure to facilitate gripping and force application when the lid 100 is twisted. The anti-slip structure may be a combination of one or more of stripes, protrusions 241 , and grooves 310 .

[0065] like Figure 3 As shown, the cover 100 may include an outer cover 110 and an inner cover 120 embedded in the inner surface of the outer cover 110. The outer cover 110 may be made of a metal part, and the inner cover 120 may be made of an elastic non-metallic part. The inner surface of the inner cover 120 is provided with an internal thread to facilitate screw connection with the container 10; a ring 121 may be formed near the through hole of the inner cover 120, and the diameter of the ring 121 is adapted to the diameter of the air guide tube 21.

[0066] The driving rod 240 may be a hollow rigid member, such as a hollow and lightweight rigid non-metallic member. Specifically, the driving rod 240 may be made of food-grade polypropylene; the float 230 may also be made of food-grade polypropylene.

[0067] 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 protection scope of the present invention.
