CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is a National Stage Entry of International Application No. PCT / KR2024 / 009042, filed on 06-27-2024, which claims priority to and the benefit of Korean Patent Application No. 10-2023-0048605, filed on April 11, 2024 and Korean Patent Application No. 10-2023-0083453, filed on June 28, 2023, in the Korean Intellectual Property Office, the disclosures of which are incorporated herein by reference in their entireties.TECHNICAL FIELD

[0002] The present invention relates to an aerating device, and more particularly, to an aerating device including preserver and stopper functions.

[0003] Furthermore, the present invention relates to a multifunctional wine pump and a multifunctional wine accessory, and more particularly, to a multifunctional wine pump that may be used at the inlet of a commercially packaged wine and has functions of a wine cutter, opener, aerator, pump, stopper, and preserver - thereby facilitating the opening, consumption, and storage of wine with a single product.BACKGROUND ART

[0004] Generally, wine undergoes very slow aging during storage due to a minute amount of oxygen entering through fine gaps in the cork. During the long aging or maturation process, sediment is formed within the wine. Most of these sediments are filtered out during the bottling process, but some sediment may remain. Accordingly, the process of filtering sediments from the wine in the wine bottle is called decanting, and the instrument used for this is called a decanter. By using such a decanter, wine that is cleaner and free of foreign matter can be enjoyed. Additionally, through such decanter, wine undergoes an aeration process, where the wine is exposed to air for a predetermined period of time. Through this aeration process, a more mature, high-quality wine can be enjoyed. That is, when sufficiently aged wine is brought into contact with oxygen in the air using a decanter - namely, when the wine is aerated - the aroma of the wine is enhanced and the taste becomes smoother.

[0005] In the case of a wine bottle-coupled wine decanter, which is coupled to a wine bottle, decanting can be easily performed, because the decanting process takes place simultaneously while pouring the wine from the wine bottle. During the process of performing wine decanting using such wine bottle-coupled wine decanter, the wine naturally has a substantial contact time with air, so the process of aerating the wine takes place, allowing the wine to have a more favorable taste.

[0006] Meanwhile, once a wine is opened, it is difficult to preserve it, because it easily oxidizes due to the air entering the bottle. As a method for preserving an opened wine, there is a method of injecting nitrogen or argon into the bottle to expel the oxygen inside the bottle to the outside. As another method, there is a method of expelling the air inside the wine bottle to the outside using a vacuum pump.

[0007] Conventionally, a wine aerating device for bringing wine into contact with oxygen, a wine preserver for preserving opened wine, and a stopper for sealing the wine inside the bottle from the outside have been used as separate accessories.

[0008] Generally, wine is aged slowly as oxygen enters the wine bottle through the cork gaps over a long period, and when the aging is complete for a certain period, it is sealed by wrapping the cork and opening of the wine bottle and shipped out as a commercial wine.

[0009] After purchase, the consumer cuts and removes the sealing material (wrapping in plastic or the like around the wine bottle opening), removes the cork stopper, and then performs the aeration process to improve the taste of the wine is performed in order to consume what would be a sufficiently mature wine. When storing the remaining wine, the wine bottle opening is blocked as much as possible to prevent further oxygen from entering from the outside, thereby preventing rapid oxidation of the remaining wine and retaining the aroma and taste as much as possible.

[0010] Conventionally, separate accessories exist and are sold for opening, consuming, and storing wine as described above: a cutter for removing the sealing around the wine bottle opening, an opener for opening the wine by separating the cork stopper from the wine bottle, a wine aerating device that assists the aeration process by exposing the wine to air for a certain period of time when consuming to allow a more mature wine to be enjoyed, a wine preserver for preserving the opened wine, and a stopper for sealing the remaining wine in the wine bottle from the outside.

[0011] However, if there are many accessories required to enjoy wine, managing (e.g., storing) them is difficult; and especially for beginners, there exists a concern that correct use may be difficult, because they may not be sufficiently knowledgeable of the function of each accessory or may find the correct use difficult.

[0012] In addition, because the methods of use and parts / components are individualized for each and the size is also small, there exists a concern that the user may lose them. There also exists the hassle of including to figure out how to use the aerating device to perform the aerating task, and there even exists a concern that the user may miss this step and consume the wine, making it difficult to enjoy the wine to the fullest.SUMMARY OF THE INVENTION TECHNICAL PROBLEM

[0013] A technical object to be achieved by the present invention is to provide a multifunctional aerating device equipped with both a wine preserver function for preserving an opened wine and a stopper function for sealing the wine inside the bottle from the outside.

[0044] Hereinafter, preferred embodiments of the present invention are described in more detail with reference to the accompanying drawings.

[0045] FIG. 1A is a diagram showing a first (1st) state of a multifunctional aerating device (1) according to an embodiment of the present invention, and FIG. 2B is a diagram showing a second (2nd) state of the multifunctional aerating device (1) according to an embodiment of the present invention.

[0046] The multifunctional aerating device (1) (hereinafter referred to as the "aerating device") according to the embodiment is an aerating device that is installed at an opening or the mouth of a bottle containing liquid and has both a stopper and a preserver function. The aerating device (1) makes the liquid pour smoothly and well when the bottle is tilted to pour the liquid, and improves the aerating effect by increasing the contact area and time with air. In addition, the aerating device (1) may also function as a stopper, such as a cap, that communicates (e.g., fluidly connects) with or seals the inside of the bottle with the outside while coupled to the bottle. In addition, the aerating device (1) may function as a preserver for preserving the liquid in the bottle by sealing the bottle while the air inside the bottle is discharged by an air pump when attached or coupled with the air pump. The aerating device (1) is installed and used at the opening of the bottle containing the liquid, and may typically be used in a state coupled to the mouth of a wine bottle.

[0047] The aerating device (1) may comprise a fluid moving channel unit (11) and a discharge control unit (12).

FIG. 5 is a diagram showing a perspective view of the discharge control unit according to an embodiment of the present invention in the 2nd state. FIG. 6A is a diagram showing an exploded perspective view of the discharge control unit as viewed from above. FIG. 6B is a diagram showing an exploded perspective view of the discharge control unit as viewed from below.

[0060] The detailed configuration of the discharge control unit (12) will be described below with reference to FIG. 4 through FIG. 6B.

[0061] The discharge control unit (12) may comprise a fluid pipe unit (121), a chamber unit (122), and a sealing control unit (123).

[0062] The chamber unit (122) may be rotatably accommodated in the coupling unit (111) of the fluid moving channel unit (11), and may comprise a fluid flowing space in which fluid flows. The fluid pipe unit (121) may communicate with the fluid flowing space in the chamber unit (122), and may have a Venturi tube shape with a varying diameter. The sealing control unit (123) may comprise an elastic material such as rubber or silicone, be coupled with a pump to discharge air, and be configured to maintain the seal inside the bottle when the inside of the bottle is depressurized.

[0063] The chamber unit (122) may further comprise a through-pipe unit (112p) and a valve seat (122s). The through-pipe unit (112p) may be configured to form a fluid moving channel for discharging the air inside the bottle. A valve seat (122s) may be provided at an upper end of the through-pipe unit (112p). A lower end of the through-pipe unit (112p) may be configured to pass through a through-hole (112h) provided at a lower part of the chamber unit (122). The valve seat (122s) formed at the upper end of the through-pipe unit (112p) may be configured to maintain airtightness in the bottle by being in close contact with the sealing control unit (123).

[0064] The chamber unit (122) may further comprise an air inlet (122th) and a liquid inlet (122ah). The air inlet (122ah) may be configured so that the outside air flows into the chamber unit (122), and the liquid inlet (122th) is configured so that the liquid in the bottle flows into the chamber unit (122) through the fluid moving channel unit (11).

[0065] A chamber plate (122q) may be provided near the liquid inlet (122th) of the chamber unit (122). In the 1st state, when the liquid flows out through the liquid inlet (122th), the aerating effect may be reduced if the liquid is directly transferred to the fluid pipe unit (121) through the space of the chamber unit (122). The liquid flowing out from the liquid inlet (122fh) is transferred to the fluid pipe unit (121) along a / the path flowing along the inner wall of the chamber unit (122) by the chamber plate (122q), thereby maximizing the aerating effect.

[0066] The discharge control unit (12) may comprise a pair of coupling protrusions (122t) (122t1, 122t2) formed at opposing positions. The fluid moving channel unit (11) may comprise a pair of coupling grooves (11th) formed at positions corresponding to the coupling protrusions (122t). State switching between the 1st state and the 2nd state may be performed by rotation of the discharge control unit (12) around the pair of coupling protrusions (122t) as a rotation axis.

[0067] In another embodiment, one or more coupling protrusions (122t) may be provided, and the fluid moving channel unit (11) may comprise one or more coupling grooves (11th) formed at positions corresponding to the coupling protrusions (122t), and the discharge control unit (12) may be configured to rotate in a state coupled to the fluid moving channel unit (11). In the embodiment of the present invention, the discharge control unit (12) is shown to rotate by the coupling protrusions (122t) and the coupling grooves (111h); however, the configuration that allows the discharge control unit (12) to rotate by other methods beside the coupling protrusion (122t) and the coupling groove (111h) are also within the technical scope of the present invention.

[0068] FIG. 7 is a cross-sectional view explaining the fluid discharge flow when the multifunctional aerator device (1) performs an aerating function in the 1st state.

[0069] In the 1st state, when the opening of the bottle containing the liquid (wine, etc.) is lowered, the liquid in the bottle may be discharged to the 1st communication hole (112h1) through the liquid moving channel of the insertion unit (113). In the 1st state, the 1st communication hole (112h1) communicates with the liquid inlet (122th), so the liquid may flow into the chamber unit (122) through the liquid inlet (122th). The liquid discharged through the liquid inlet (122th) by the chamber plate (122q) in the chamber unit (122) does not flow directly into the fluid pipe unit (121), but may flow into the fluid pipe unit (121) along the inner wall surface of the chamber unit (122). The liquid introduced may be discharged to the outside through the Venturi tube-shaped fluid pipe unit (121). Aerating of the liquid may be performed via contact with the air (oxygen) as a flow rate of the liquid increases in a narrow part of the Venturi tube-shaped fluid pipe unit (212).

[0070] FIG. 8 is a diagram showing a cross-sectional view explaining the air discharge flow when the multifunctional aerator device performs stopper and preserver functions in the 2nd state.

[0071] In the 2nd state shown in FIG. 8, when a pumping operation is performed through the air pump on an upper part of the sealing control unit (123), the air in the bottle may flow into the through-pipe unit (112p) in the chamber unit (122) through the 1st communication hole (112h1) and the through-hole (112h) via the air moving channel in the insertion unit (113). The air flow in the through-pipe unit (112p) may be discharged to the outside through the gap between the valve seat (122s) and the sealing control unit (123). When the air in the bottle is discharged to the outside, the inside of the bottle has a lower pressure than the outside. In such situation, a force acts from the outside of the sealing control unit (123) toward the inside of the bottle, and the sealing control unit (123) is brought into close contact with the valve seat (122s), and the gap between the sealing control unit (123) and the valve seat (122s) may thus be sealed. When the housing of the sealing control unit (12) is pushed to the left or right in the sealed state by depressurization, the outside air flows in from the gap between the sealing control unit (12) and the valve seat (122s), and the depressurized state may be released / cancelled.

[0073] Hereinafter, a multifunctional wine pump and a multifunctional wine accessory are described with reference to FIG. 9 to FIG. 15.

[0074] The present invention relates to a multifunctional wine pump and a multifunctional wine accessory, and more particularly, to a multifunctional wine pump and multifunctional wine accessory that may be used at the opening of a packaged wine and has / have integrated functions of a wine cutter, opener, aerator, pump, stopper, and preserver, thereby facilitating the opening, consumption, and storage of wine with one single product.

[0075] Such multifunctional wine accessory (2) comprises: a multifunctional wine pump (1000) (hereinafter referred to as "wine pump") that may be applied to a sealed wine bottle opening to perform cutter, opener, and pump functions; and a wine stopper (2000) that may be mounted on an upper end of a wine pump (1000) and has an interior communicating with each other (e.g., other part), and may be attached (coupled) to or detached (separated) from the wine pump (1000) as needed, to perform aerator, stopper, and preserver functions.

[0076] The wine pump (1000) may comprise a cutter frame (1100) for removing the sealed packaging such as foil or vinyl at the opening of the commercial wine, an opening frame (1200) coupled to the cutter frame (1100) and communicating with an inside of the cutter frame (1100) to separate the cork stopper from the sealed packaging at the opening that is cut in order to open the wine, and a pump frame (1300) communicating with the inside of the cutter frame (1100) and the opening frame (1200) and performing a pump function of introducing or discharging air into or out of the wine bottle through a vertical operation.

[0077] The cutter frame (1100), the opening frame(1200), and the pump frame (1300) are cylindrical in form and may be coupled integrally, and a hole may be formed at one end of the wine pump (1000) so that a part of a lower end of the wine stopper (2000) may be inserted and fixed.

[0078] The cutter frame (1100) has a cylindrical shape, but a diametric width of a lower end of the cutter frame (1100) may be formed to be wider than a diametric width of an upper end of the cutter frame (1100) so that the wine pump (1000) and the wine stopper (2000) may be securely mounted and fixed on the ground or a surface.

[0079] Upper and lower surfaces of the cutter frame (1100) may be open, but are fitted into an inner lower end of the opening frame (1200).

[0080] Inside the cutter frame (1100), an insertion hole (1110) is formed, which is positioned in an up-and-down direction with an opening hole (1220) (to be described later) so that the insides thereof communicate with each other, and the insertion hole (1110) is also formed in which a lower end portion of a screw (1210) is located. On one lower surface of the cutter frame (1100), an entry hole (1120) is formed, which is recessed with a predetermined width in an upward direction to allow the opening of a wine bottle to be positioned therein, and a cutter (1130) capable of removing the sealing material at the wine bottle opening is formed at an inner edge of the entry hole (1120).

[0081] Accordingly, when a user positions a sealed portion of the wine bottle inside the entry hole (1120) and then rotates the wine pump (1000) including the cutter frame (1100), the cutter (1130) comes into contact with the sealed portion, whereby the sealed portion can be cut by the cutter (1130). The user can easily grasp and tear off the torn seal portion.

[0082] Through the entry hole (1120) and the cutter (1130), the present invention may be applied in a variety of ways to different wine bottle openings, and the sealed portion may be removed while only the outer surface of the wine bottle opening is in close contact. Since the cutter (1130) is not exposed to the outside, the seal portion are safely removed. This applies not only to wine bottle openings that are sealed with foil or the like, but also to cases where a vinyl cover or the like is tightly attached under high pressure; by positioning the wine bottle opening inside the entry hole (1120) and then rotating it, the cutter (1130) and the wine bottle opening are brought into close contact to enable cutting / tearing and removal.

[0083] The opening frame (1200) has a cylindrical shape and is provided with the cutter frame (1100) at a lower inner side thereof, and performs an opener function to remove a cork stopper that closes the wine bottle opening by being coupled thereto in communication with the inside of the insertion hole (1110) of the cutter frame (1100).

[0084] The opening frame (1200) has a cylindrical shape and may comprise: a screw (1210) configured to penetrate into the cork stopper through rotation in one direction and then separate the cork stopper from the wine bottle opening through rotation in the opposite direction; and an opening hole (1220) having the screw (1210) provided at an inner center thereof and having an inside communicating with the insertion hole (1110) so that the wine bottle opening including the cork stopper may be positioned therein.

[0085] The screw (1210) has a shape of a metal screw used in a wine opener, and a lower end thereof is located at the inner center of the insertion hole (1110) of the cutter frame (1100) so that when the user inserts the wine bottle opening into the insertion hole (1110), the lower end of the screw (1210) may be coupled after being brought into close contact with the cork stopper. An upper end of the screw (1210) is coupled and fixed to an inner frame (1320) of a pump frame (1300) (to be described later), and when the user rotates the wine pump (1000), the screw also rotates along the fixed pump frame (1300) to pull the coupled cork stopper out from the wine bottle opening.

[0086] The user may easily rotate the wine pump (1000) through friction protrusions (1311) of an outer frame (1310), and through this, the user may rotate and lift the wine pump (1000) including the screw (1210) coupled through the cork stopper, thereby performing an opener function to remove the cork stopper.

[0087] The opening hole (1220) is a hollow formed in a height direction along the inner center of the opening frame (1200), and when the cutter frame (1100) is provided at the inner lower end of the opening frame (1200), the opening hole (1220) may communicate with the inside of the insertion hole (1110). The screw (1210) is located inside the opening hole (1220), and the opening of the cork stopper may be coupled with the screw (1210) within the opening hole (1220).

[0088] The user may use the opener function to remove the cork stopper through a rotation by coupling the wine bottle opening and the wine pump (1000). A checking hole (1230) is formed by perforation on one side of the front surface so that it can be easily checked from the outside whether the cork stopper is being properly coupled and fixed to the screw (1210) and removed.

[0089] Accordingly, the user may easily, visually confirm whether the wine pump (1000) rotates in one direction such that the screw (1210) penetrates and is fixed to the cork stopper in the wine bottle opening, and when rotated in the other direction (opposite to the "one direction"), the cork stopper coupled with the screw (1210) moves in an upward direction to facilitate the separation of the cork stopper, i.e., the opening of the wine, without needless turning.

[0090] The pump frame (1300) may perform a role of discharging air (oxygen) inside the wine bottle. The pump frame (1300) may comprise an outer frame (1310) and an inner frame (1320).

[0091] The outer frame (1310) is provided on the outside and located at an outer upper end of the wine pump (1000), and may be configured to be gripped and rotated by a user. The inner frame (1320) is provided inside the outer frame (1310) and is connected to the screw (1210), and an outer surface thereof is spaced apart from an inner surface of the outer frame (1310) to be configurable to introduce or discharge air through such gap / space.

[0092] On the outer upper end of the outer frame (1310), a plurality of friction protrusions (1311) are to protrude at predetermined intervals so that the user can easily grip and rotate the wine pump (1000) including the pump frame (1300) through frictional force. Accordingly, by grasping and rotating the outer surface of the outer frame (1310) including the friction protrusions (1311), rotation or movement in an up-and-down direction of the pump frame (1300) is possible.

[0093] The inner frame (1320) has a cylindrical shape identical to that of the outer frame (1310), but an outer diameter of the inner frame (1320) is smaller than an inner diameter of the outer frame (1310) such that the gap formed by spacing exists between the inner frame (1320) and the outer frame (1310). An upper surface of the inner frame (1320) is open to allow the wine stopper (2000) to be inserted therein, and an upper end of the screw (1210) is coupled and fixed to the center of a lower surface thereof.

[0094] In such instance, a rail groove (1321) recessed along a longitudinal direction is formed at one part of an outer surface of the inner frame (1320). This rail groove (1321) serves to guide a rail protrusion (1312), which protrudes from the inner surface of the outer frame (1310) and is inserted into the rail groove (1321), to move along the rail groove (1321) when the outer frame (1310) moves in an up-and-down direction.

[0095] In such instance, a protruding length of the rail protrusion (1312) is formed to be longer than a recessed length of the rail groove (1321) so that the outer frame (1310) and the inner frame (1320) are coupled such that a / the gap occurs between the inner surface of the outer frame (1310) and the outer surface of the inner frame (1320).

[0096] Accordingly, a gap occurs between the upper end of the inner frame (1320) and the upper end of the outer frame (1310), and a packing member (1322) capable of sealing this gap is formed along an outer peripheral surface of the upper end of the inner frame (1320).

[0097] The packing member (1322) may have a truncated cone shape with a slope that gradually widens toward the bottom. When the inner frame (1320) moves to the opposite side of the wine bottle (upward arrow direction in FIG. 14) and the inner frame (1320) is exposed to the outside, the packing member (1322) comes into close contact with the outer surface of the inner frame (1320) to close the gap between the inner surface of the outer frame (1310) and the outer surface of the inner frame (1320), thereby maintaining airtightness. Accordingly, a second communication hole (2122) of the wine stopper (2000) (to be described later) is opened through the packing member (1322), and the air inside the wine bottle is sucked toward the wine stopper (2000) through the second communication hole (2122).

[0098] When the inner frame (1320) moves in a direction toward the wine bottle (downward arrow direction in FIG. 14) so that the inner frame (1320) is positioned inside the outer frame (1310), the state in which airtightness was maintained by the close contact between the packing member (1322) and the inner surface of the outer frame (1310) is released / cancelled. When the airtight state is released, the previously opened second communication hole (2122) is closed. Accordingly, air between the inner surface of the outer frame (1310) and the outer surface of the inner frame (1320) is discharged to the outside through the gap between the packing member (1322) and the outer frame (1310).

[0099] Therefore, by driving the pump frame (1300) through manual force, air remaining inside the wine bottle is sucked into the wine stopper (2000) and then discharged to the outside, whereby the air remaining inside the wine bottle may be vacuum-sucked. According to this configuration, the air inside the wine bottle is discharged to the outside to create a vacuum state inside the wine bottle, enabling the wine to be stored for a long period without denaturation.

[0100] Through the wine pump (1000) described above, the roles of a wine cutter, an opener, and a pump may be performed. In addition, the wine pump (1000) may be detachably couplable to one end of the wine stopper (2000) and may have a cylindrical shape to also perform a role of a holder that stably supports the wine stopper (2000).

[0101] FIG. 16 is a diagram showing a coupling frame, according to the present invention. FIG. 17A and FIG. 17B respectively show a front perspective view and rear perspective view of the discharge frame, according to the present invention. FIG. 18A and FIG. 18B respectively show the front and rear perspective views of the discharge frame as disassembled, according to the present invention.

[0102] Hereinafter, a wine stopper (2000), which is detachably couplable to the wine pump (1000), is described with reference to FIG. 16 to FIG. 18B.

[0103] The wine stopper (2000) may have functions of an aerator, a preserver, and a stopper. The wine stopper (2000) may comprise: a coupling frame (2100) provided with a / the fluid moving channel and having a lower portion inserted into an upper end of the wine pump (1000); and a discharge frame (2200) coupled to the coupling frame (2100) and provided with a flow path communicating with the fluid moving channel; and a discharge port for discharging liquid, i.e., wine.

[0104] The coupling frame (2100) may comprise a coupling frame body (2110), a sealing unit (2120), an insertion unit (2130), and a flow tube (2140).

[0105] The coupling frame body (2110) may be coupled to an outer part of the discharge frame (2200) and may be configured in a hemispherical shape as shown in FIG. 16, but is not limited thereto.

[0106] The coupling frame body (2110) has a hollow space there-within so that the discharge frame (2200) may be provided in a form inserted into the inside thereof.

[0107] The sealing unit (2120) may comprise a first communication hole (2121) communicating with a liquid movement channel of the insertion unit (2130) and a second communication hole (2122) communicating with an air moving channel of the flow tube (2140). The sealing unit (2120) is configured to be in close contact with a part of a housing of the discharge frame (2200) to maintain airtightness between the part of the housing of the discharge frame (2200) and the coupling frame body (2110). In such instance, the sealing unit (2120) is made of a material having elasticity, such as rubber or silicone, to improve airtightness.

[0108] The coupling frame body (2110) may be formed with a plurality of cut-out grooves (2111), and these cut-out grooves (2111) may facilitate the coupling between the coupling frame body (2110) and the discharge frame (2200), even if there is a gap or clearance when the coupling frame (2100) and the discharge frame (2200) are coupled. In addition, a rotation groove (2112) - into which a rotation protrusion (2220a) of the discharge frame (2200) (to be described later) is fitted and coupled - is recessed inside the coupling frame body (2110) so that the discharge frame (2200) may rotate with respect to the rotation protrusion (2220a).

[0109] Through the coupling between the rotation groove (2112) and the rotation protrusion (2220a), the discharge frame (2200) may easily rotate in a predetermined direction inside the coupling frame (2100).

[0110] The insertion unit (2130) communicates with the inside of the coupling frame body (2110) and has a pipe shape that extends and protrudes downward so that a part of the insertion unit (2130) may be inserted into the wine bottle. In such instance, the insertion unit (2130) has a shape in which a diameter gradually decreases toward the lower side, and a liquid movement channel through which liquid in the wine bottle can move is formed therein.

[0111] The movement tube (2140) is inserted into the insertion unit (2130) to form an air moving channel through which external air moves into the wine bottle.

[0112] The discharge frame (2200) may comprise a fluid pipe (2210), a discharge frame body (2220), and a sealing control member (2230).

[0113] The discharge frame body (2220) may be received inside the coupling frame body (2110) so as to be rotatable and may include a fluid moving space therein through which fluid moves.

[0114] The fluid pipe (2210) communicates with the fluid moving space in the discharge frame body (2220) and may have a Venturi tube shape with a varying diameter.

[0115] The sealing control unit (2230) is made of a material having elasticity, such as rubber or silicone, and is coupled with the wine pump (1000) to discharge the air and is configured to maintain the wine bottle in a sealed state when the inside of the wine bottle is decompressed.

[0116] In such instance, the discharge frame body (2220) may further comprise a through-pipe (2221) and a valve seat (2222). The through-pipe (2221) is configured to form the fluid moving channel for discharging the air from the inside of the wine bottle, and the valve seat (2222) is formed at an upper end of the through-pipe (2221). In addition, a lower end of the through-pipe (2221) may be configured to pass through a through-hole (2220b) provided at a bottom of the discharge frame body (2220). The valve seat (2222) formed at the upper end of the through-pipe (2221) may be configured to be in close contact with the sealing control unit (2230) to maintain airtightness inside the wine bottle.

[0117] The discharge frame body (2220) may further comprise an air inlet (2223) and a liquid inlet (2224). The air inlet (2223) is configured such that external air may be introduced into the discharge frame body (2220), and the liquid inlet (2224) is configured such that liquid in the wine bottle may be introduced into the discharge frame body (2220) through the coupling frame (2100).

[0118] In such instance, a body plate (2225) may be provided around the liquid inlet (2224). That is, when the liquid flows out through the liquid inlet (2224) in a first state, if the liquid is directly transferred to the fluid pipe (2210) through the space of the discharge frame body (2220), the aerating effect may be halved. Therefore, the liquid flowing out from the liquid inlet (2224) is transferred to the fluid pipe (2210) via a path flowing along an inner wall of the discharge frame body (2220) by the body plate (2225), thereby maximizing the aerating effect.

[0119] When the discharge frame (2200) is inserted into the coupling frame (2100), a rotation protrusion (2220a) is formed to protrude at a position corresponding to the aforementioned rotation groove (2112). As the rotation protrusion (2220a) is inserted into and fitted with the rotation groove (2112), the discharge frame (2200) is rotated with respect to an axial direction of the rotation protrusion (2220a).

[0120] Through this rotation of the discharge frame (2200), the state may be switched as needed between the 1st state as shown in FIG. 20 and the 2nd state as shown in FIG. 21.

[0121] In such instance, the rotation protrusion (2220a) may be formed as a single unit or a plurality of units, and the rotation groove (2112) may be also recessed in the same number and position as the rotation protrusion (2220a). The discharge frame (2200) may be rotated directly inside the coupling frame (2100), or the discharge frame (2200) may be rotated to the position of the first or the second state in advance and then coupled with the coupling frame (2100). Not limited to rotation through axial coupling such as the rotation protrusion (2220a) and the rotation groove (2112), various other forms of coupling and rotation methods may be implemented through configuration changes.

[0122] After the wine stopper (2000) is coupled to the wine bottle in the 1st state as shown in FIG. 20, the opening of the wine bottle is tilted so that the liquid (wine) inside the wine bottle may be discharged to the first communication hole (2121) through the liquid moving channel of the insertion part (2130). In this first state, since the first communication hole (2121) and the liquid inlet (2224) communicate with each other, the liquid flows into the discharge frame body (2220) through the liquid inlet (2224). The liquid discharged through the liquid inlet (2224) is not directly introduced into the fluid pipe (2210) due to the body plate (2225) in the discharge frame body (2220), but flows along the inner wall surface of the discharge frame body (2220) and then enters the fluid pipe (2210). The introduced liquid is discharged to the outside through the Venturi-shaped fluid pipe (2210). In such instance, the flow rate of the liquid increases at the portion where the diameter narrows due to the Venturi tube shape of the fluid pipe (2210), and an aerating effect occurs due to contact with external air (or oxygen).

[0123] Additionally, in the 2nd state as shown in FIG. 21, when the upper part of the sealing control member (2230) performs the pumping operation through the pump frame (1300), the air inside the wine bottle may be introduced into the through-pipe (2221) in the discharge frame body (2220) via the air moving channel in the insertion part (2130), the first communication hole (2121), and the through-hole (2220b).

[0124] In such instance, the air flow in the through-pipe (2221) passes through the gap between the valve seat (2222) and the sealing control member (2230) and is discharged to the outside through the gap between the outer frame (1310) and the inner frame (1320) of the pump frame (1300). When the air inside the wine bottle is discharged to the outside, the inside of the wine bottle has a relatively lower air pressure than the outside. When such decompression occurs, a force directed from the outside of the sealing control unit (2230) toward the inside of the wine bottle is applied, causing the sealing control unit (2230) to come into close contact with the valve seat (2222), thereby sealing the space between them. Similarly, the packing member (1322) also closes the gap between the inner surface of the outer frame (1310) and the outer surface of the inner frame (1320), completing the sealing of the wine bottle.

[0125] Furthermore, when pressure is applied to a part of the housing of the sealing control unit (2230) in an upward direction while in a sealed state due to decompression, the sealing control unit (2230) moves, allowing external air to be introduced through the gap between the sealing control unit (2230) and the valve seat (2222), thereby releasing the decompressed state.

[0126] The discharge frame (2200) is formed of a transparent material so that the liquid movement state may be checked from the outside, allowing the discharge of wine to be visually confirmed.

[0127] For ordinary use, the wine stopper (2000) may be coupled to the upper end of the wine pump (1000) so it can be placed at an installation site. When performing the pumping operation through the pump frame (1300) while coupled with the wine pump (1000), the wine stopper (2000) also serves to discharge the air introduced into the wine bottle to the outside by maintaining or releasing the airtight state inside the pump frame (1300) together with the packing member (1322).

[0128] In addition, when the wine stopper (2000) is separated from the wine pump (1000) and coupled directly to the wine bottle opening, it allows the wine to be poured smoothly when the bottle is tilted. It enhances the aerating effect by increasing the contact area and time with air and may also function as a stopper that connects or closes off the inside of the wine bottle to the outside.

[0129] The wine pump (1000) and wine stopper (2000) may be kept in a wine display case or the like with the stopper coupled to the pump. As needed, the wine pump (1000) may be used to cut the seal and open the wine, and then the wine stopper (2000), separated from the pump and coupled to the bottle opening, providing the advantage of functioning as an aerator, pump, stopper, and preserver.

[0130] Furthermore, even if the wine stopper (2000) is coupled with another wine bottle, the wine pump (1000) may still be used as a sealing-material cutter and opener for other wines. Thus, it has the advantage of being usable in various ways by attaching or detaching the wine stopper (2000) and the wine pump (1000), as needed.

[0131] FIG. 22 is a diagram showing the wine cutter, according to another embodiment of the present invention.

[0132] Referring to FIG. 22, the opening frame (1200) may be provided with a cutting member (1250) near a checking hole (1230). The cutting member (1250) may be generally, bracelet-shaped and may be manufactured in a shape in which a part of a ring-shaped plate is cut out near the checking hole (1230). The cutting member (1250) may include two ends (1251).

[0133] The checking hole (1230) may be formed to have an area larger than the opening of a wine bottle, and the cutting member (1250) may be manufactured such that a gap between both ends (1251) of the cutting member (1250) narrows when both side surfaces of the cutting member (1250) are pressed.

[0134] When a user presses the side surfaces of the cutting member (1250) in a state where the wine bottle opening is inserted into the checking hole (1230), (the) both ends (1251) come into contact with a sealing (foil) of the wine bottle opening. In this state, the sealing of the wine bottle opening may be easily cut by the user rotating the wine bottle or rotating the cutting member (1250) and the opening frame (1200).

[0135] The foregoing description of the present invention is for illustrative purposes, and those skilled in the art to which the present invention pertains will understand that the present invention may be easily modified into other specific forms without departing from the technical spirit or essential characteristics thereof. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not limited. For example, each element described as a singular entity may be separately implemented, and similarly, elements described as being separated may also be implemented in a combined form.

[0136] The scope of the present invention is defined by the claims to be recited later, and all changes or modifications derived from the subject matter and scope of the claims and their equivalents should be interpreted as being included in the scope of the present invention.Reference Numerals:
