Description

Technical Field

[0001] This utility model specifically relates to press-to-expand wine bottle stoppers, belonging to the field of bottle stopper technology. Background Technology

[0002] A wine bottle is a container that is open at one end and closed at the other, used to hold liquid alcoholic beverages; a bottle stopper is a sealing component that can be inserted into the opening and, by relying on a tight fit, prevents the liquid and gas inside the bottle from escaping, while also preventing outside air and impurities from entering.

[0003] Once a bottle of red wine is opened, the original cork at the neck of the bottle will usually be deformed or broken and cannot be reused. Even if it can be reused, the sealing effect of the cork at the bottle neck will decrease, causing air to continuously seep in and the aroma to fade quickly. Common universal rubber stoppers or disposable plastic stoppers on the market have a fixed taper, which is either too tight and difficult to insert or too loose and easy to fall off when facing bottle necks with different inner diameters. After repeated insertion and removal, they are more prone to aging and cracking, further reducing the reliability of the seal. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a press-to-expand bottle stopper to solve the problems mentioned in the background section.

[0005] Press and expand the bottle cork, including:

[0006] The main body is columnar, and an axial insertion hole is formed inside it for guidance.

[0007] The extrusion mechanism is slidably inserted into the insertion hole and can move along the axial direction of the main body.

[0008] A sealing assembly, which is sleeved on the extrusion mechanism and abuts against the main body, is used to generate radial expansion when the extrusion mechanism moves;

[0009] The pressing component is disposed on the upper end of the main body and is connected to the extrusion mechanism for driving the extrusion mechanism to slide within the insertion hole, thereby causing the sealing component to form a recoverable deformation blockage state within the bottle mouth.

[0010] Furthermore, a flip groove is provided on the top of the main body at the location of the insertion hole.

[0011] Furthermore, the extrusion mechanism includes:

[0012] A lifting column, which is slidably inserted into the insertion hole, and a base plate is fixed to the bottom of the lifting column;

[0013] A rectangular column is fixed to the top of the lifting column, and a first connecting hole is provided on the rectangular column.

[0014] Furthermore, the sealing assembly includes:

[0015] The first rubber ring is fitted onto the lifting column, and the bottom of the first rubber ring abuts against the chassis.

[0016] A sleeve is fitted onto the lifting column, and the bottom of the sleeve abuts against the top of the first rubber ring.

[0017] The second rubber ring is sleeved on the lifting column, with its bottom abutting against the top of the sleeve and its top abutting against the main body.

[0018] Furthermore, the first and second rubber rings are made of rubber.

[0019] The sleeve is made of ABS material.

[0020] Furthermore, the pressing component includes:

[0021] A cover plate, on which a connecting seat is fixed, the connecting seat being adapted to be embedded in the flip groove;

[0022] A second connecting hole is formed on the connecting seat, and a connecting pin is inserted into the second connecting hole. The connecting pin is adapted to be inserted into the first connecting hole.

[0023] Furthermore, a first contact surface is provided on one side of the connector, and a second contact surface is provided on the other side. The distance between the second connecting hole and the first contact surface is greater than the distance between the second connecting hole and the second contact surface.

[0024] Beneficial effects:

[0025] This invention integrates the main body and the protruding post into a single unit with a coaxial insertion hole, ensuring the extrusion mechanism moves linearly within the insertion hole and preventing swaying, thus guaranteeing uniform force on the sealing component. The lifting post and the base work together to compress the sealing component, causing it to expand radially within the bottle neck, forming a continuous and stable sealing ring. This effectively overcomes the problem of traditional conical stoppers being too tight or too loose due to dimensional errors. The lever stroke amplification structure formed by the first and second contact surfaces of the connecting seat allows for a larger radial expansion with a smaller pressing stroke, improving sealing force while reducing operating effort. This bottle stopper can fit tightly to various bottle neck sizes with the same body. It releases instantly after pressing and can be pulled out with one hand, eliminating the need to re-press deformed bottle caps or repeatedly cut corks. This completely avoids the problems of traditional stopper breakage, debris falling into the wine, and the additional consumables required for secondary sealing. The entire unit is reusable, significantly extending its service life and reducing both production and usage costs. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1-6 As shown, pressing the expanding bottle cork includes:

[0035] The main body 1 is columnar, and an axial insertion hole 3 is formed inside it for guidance.

[0036] The extrusion mechanism is inserted into the insertion hole 3 in a sliding fit manner and can move along the axial direction of the main body 1.

[0037] A sealing assembly, which is sleeved on the extrusion mechanism and abuts against the main body 1, is used to generate radial expansion when the extrusion mechanism moves;

[0038] The pressing component is disposed on the upper end of the main body 1 and is connected to the extrusion mechanism for driving the extrusion mechanism to slide within the insertion hole 3, thereby causing the sealing component to form a recoverable deformation blockage state within the bottle mouth.

[0039] In this embodiment, after the main body 1 is vertically inserted into the bottle mouth, the user can push the pressing component, and the driving force will drive the squeezing mechanism to move smoothly downward in the insertion hole 3 through axial transmission. The outer conical surface of the squeezing mechanism gradually squeezes the sealing component, and the sealing component will expand radially in sync under the axial thrust. The outer edge will evenly fit against the inner wall of the bottle mouth to form a continuous circumferential sealing band. When it is necessary to open the bottle mouth, the pressing component is pulled in the opposite direction, the squeezing mechanism will reset upward, and the sealing component will retract under its own elasticity and disengage from the inner wall of the bottle mouth, so it can be easily pulled out. The whole process does not require rotation, and only a single press or pull is needed to complete the sealing and release. The operation is labor-saving and the sealing is reliable.

[0040] Please see Figure 1 and Figure 2 As shown, as a technical optimization of this utility model, a flip groove 2 is provided on the top of the main body 1 at the location of the insertion hole 3.

[0041] In this embodiment, the flip groove 2 opens outward from the upper edge of the insertion hole 3, allowing the pressing component to be flipped and adjusted on the main body 1 to achieve compression expansion or release of the sealing component.

[0042] Please see Figures 1-4 As shown, as a technical optimization of this utility model, the extrusion mechanism includes:

[0043] The lifting column 4 is slidably inserted into the insertion hole 3, and the bottom of the lifting column 4 is fixed with a base plate 5.

[0044] A rectangular column 6 is fixed to the top of the lifting column 4, and a first connecting hole 7 is provided on the rectangular column 6.

[0045] In this embodiment, when the lifting column 4 slides up and down along the insertion hole 3, the chassis 5 is always located at the lower end of the main body 1 and maintains coaxial contact with the sealing component, so that the sealing component is subjected to uniform force; the rectangular column 6 protrudes from the upper end of the main body 1, and its first connecting hole 7 provides a stable connection point for the pressing component, so that the downward pressure is directly transmitted along the axis of the lifting column 4, avoiding deviation, and ensuring that the axial compression of the sealing component by the chassis 5 is stable and reliable.

[0046] Please see Figures 1-5 As shown, as a technical optimization of this utility model, the sealing assembly includes:

[0047] The first rubber ring 8 is sleeved on the lifting column 4, and the bottom of the first rubber ring 8 abuts against the chassis 5.

[0048] Sleeve 9, sleeved on the lifting column 4, with the bottom of sleeve 9 abutting against the top of the first rubber ring 8;

[0049] The second rubber ring 10 is sleeved on the lifting column 4. The bottom of the second rubber ring 10 abuts against the top of the sleeve 9, and the top of the second rubber ring 10 abuts against the main body 1.

[0050] The first rubber ring 8 and the second rubber ring 10 are made of rubber.

[0051] The sleeve 9 is made of ABS material.

[0052] In this embodiment, when the lifting column 4 moves upward, the base plate 5 first pushes the first rubber ring 8, causing it to bulge radially and fit tightly against the inner wall of the bottle mouth; then the sleeve 9 moves upward, pressing the second rubber ring 10 against the lower end face of the main body 1. The second rubber ring 10 also expands outward, forming two continuous sealing rings with the first rubber ring 8. The elastic recovery force of the rubber material and the rigid support of the ABS sleeve 9 work together to ensure that the sealing rings expand fully while avoiding excessive deformation, thereby forming a reliable blockage inside the bottle mouth. The lifting column 4 can simultaneously release the seal and return to the initial position by moving in the opposite direction.

[0053] Please see Figures 1-6 As shown, as a technical optimization of this utility model, the pressing component includes:

[0054] Cover plate 11, on which a connecting seat 12 is fixed, the connecting seat 12 being adapted to be embedded in the flip groove 2;

[0055] The second connecting hole 13 is formed on the connecting seat 12, and a connecting pin 16 is inserted into the second connecting hole 13. The connecting pin 16 is adapted to be inserted into the first connecting hole 7.

[0056] The connector 12 has a first contact surface 14 on one side and a second contact surface 15 on the other side. The distance between the second connecting hole 13 and the first contact surface 14 is greater than the distance between the second connecting hole 13 and the second contact surface 15.

[0057] In this embodiment, the cover plate 11 and the connecting seat 12 are integrally formed and embedded in the flip groove 2. The connecting pin 16 passes through the second connecting hole 13 and the first connecting hole 7 at the same time, forming a rotatable hinge fulcrum. When the cover plate 11 is pressed down, it will rotate around the hinge fulcrum as the center of rotation. The first contact surface 14 first contacts the top surface of the main body 1 and acts as a short lever arm. Then the connecting seat 12 rotates around the connecting pin 16, and the second contact surface 15 becomes a long lever arm. The difference in lever arm amplifies the downward pressure and smoothly transmits it to the lifting column 4, realizing effortless pressing, smooth flipping and reliable return. This allows the first rubber ring 8 and the second rubber ring 10 to expand to adapt to the bottle mouth sealing use in different occasions.
