TECHNICAL FIELD
[0001] The utility model relates to bottle cap technical field, specifically is a kind of material silk combination formula anti-fake bottle cap. BACKGROUND
[0002] Wine is usually filled in glass bottle or porcelain bottle, and the bottle opening is sealed with a bottle cap to prevent wine from evaporating. In order to prevent counterfeiting, the bottle cap of the wine bottle is usually provided with certain anti-fake measures, for example, an anti-fake label can be provided on the bottle cap, or a pry-off opening mode is used for anti-fake. The internal explosion cap is a bottle cap with anti-fake effect. The commonly used internal explosion structure is that the lower edge of the sealing cap is in arc shape, which is called explosion edge, and is hidden in the lower cylinder of the bottle cap. When opened, the explosion edge is rubbed with the upper edge of the lower cylinder to cut off the broken material silk, which affects the quality and cleanliness of the wine. SUMMARY
[0003] The utility model discloses to solve the problem of material silk falling when the existing internal explosion cap is opened, and provides a material silk-free combination type anti-fake bottle cap, which does not produce material silk when the bottle cap is opened.
[0004] To solve the above technical problems, the utility model discloses a wine pouring nozzle which is sleeved outside the bottle opening and fixed on the bottle opening when the bottle cap is opened. The wine pouring nozzle is provided with a channel for liquid outflow. The wine pouring nozzle is inserted with a sealing cap for sealing the wine pouring nozzle. The outer side of the wine pouring nozzle is threadedly connected with a screw cap. When the screw cap is screwed, the screw cap is lifted upward relative to the wine pouring nozzle. The structural features are as follows: the wine pouring nozzle comprises a middle threaded section. The upper end of the middle threaded section is connected with the upper side wall of the wine pouring nozzle. The upper end of the upper side wall of the wine pouring nozzle is provided with an outwardly protruding outer edge. The sealing cap comprises a sealing cap plane. The lower surface of the sealing cap plane is connected with a sealing ring for sealing the upper side wall of the wine pouring nozzle. The upper surface of the sealing cap plane is peripherally connected with an upwardly and outwardly inclined and elastic inclined edge. The screw cap comprises a screw cap side wall. The upper end of the screw cap side wall is connected with a limiting upper edge which is inwardly protruding and can be in contact with the inclined edge. When the screw cap is lifted upward relative to the sealing cap, the inclined edge can slide below the limiting upper edge. The inner surface of the screw cap side wall is provided with a limiting table which is inwardly protruding and can prevent the sealing cap from passing. The limiting table is below the limiting upper edge. The limiting table, the limiting upper edge and the screw cap side wall form a limiting groove which can clamp the sealing cap. The lower surface of the sealing cap plane is peripherally connected with a snap ring which is tightly sleeved outside the outer edge and can prevent the sealing cap from being separated from the wine pouring nozzle when the screw cap is lifted upward relative to the sealing cap. The snap ring is outside the sealing ring. The limiting table is below the snap ring and not below the sealing ring.
[0005] After the parts of the bottle cap are assembled, the sealing cover is inserted into the wine pouring spout, the screw cap is screwed on the outside of the wine pouring spout, and the sealing ring seals the inner surface of the wine pouring spout to prevent liquid from evaporating and leaking. The sealing cover plane and the snap ring pass below the limiting upper edge. Since the inclined edge is inclined upward and outward, the outer diameter of the inclined edge is larger than the plane size of the sealing cover plane and other parts of the sealing cover. After the inclined edge contacts the limiting upper edge, the sealing cover is positioned, and the limiting upper edge supports the inclined edge. When the bottle cap is opened, the wine pouring spout is fixed and does not rotate or separate from the bottle mouth. The screw cap is twisted, and the screw cap is lifted upward. The snap ring is tightly sleeved on the outside of the outer edge. Under the action of the friction between the snap ring and the outer edge, the sealing cover is still inserted into the wine pouring spout and does not lift upward with the screw cap. Since the inclined edge is inclined upward and outward, the limiting upper edge exerts pressure on the inclined edge during the upward lifting of the screw cap, and the inclined edge deforms inward. When the inclined edge slides below the limiting upper edge and enters the limiting groove, the deformation of the inclined edge disappears and returns to the original state. At this time, the sealing cover enters the limiting groove, and the limiting platform limits the position of the snap ring, so that the sealing cover cannot continue to move downward. After the deformation of the inclined edge disappears, the inclined edge is located below the limiting upper edge, so that the sealing cover cannot separate upward from the limiting groove. When the screw cap continues to lift upward, the screw cap carries the sealing cover out, so that the sealing cover separates from the wine pouring spout. After the screw cap is removed, the liquid in the bottle can be poured out. When the bottle mouth is sealed again by twisting the bottle cap, the relative position of the sealing cover and the screw cap changes because the sealing cover is in the limiting groove. When the sealing cover is inserted into the wine pouring spout again, the screw cap cannot continue to twist downward. Compared with when the bottle cap is not opened, the position of the screw cap is raised and cannot return to the original position. According to the position of the screw cap, it can be judged whether the bottle cap has been opened, and the anti-fake effect is achieved. The bottle cap of the utility model will not produce silk and powder when it is opened, and the influence on the quality of the liquid is reduced.
[0006] An outer thread is arranged on the outer surface of the middle threaded section, and an inner thread that is engaged with the outer thread is arranged on the inner surface of the screw cap side wall, and the inner thread is located below the limiting platform.
[0007] The contact surface between the limiting upper edge and the inclined edge is an inclined surface, and the inclined surface has the same inclination direction as the inclined edge.
[0008] The diameter of the middle threaded section is larger than the diameter of the upper side wall of the wine pouring spout, and a lower end of the middle threaded section is connected with a lower side wall of the wine pouring spout, and the diameter of the lower side wall of the wine pouring spout is larger than the diameter of the middle threaded section.
[0009] A plurality of bottle mouth clamping claws that prevent the wine pouring spout from separating from the bottle mouth when the bottle cap is opened are arranged on the lower side wall of the wine pouring spout.
[0010] An upper outer cover that can drive the sealing cover to rotate synchronously is sleeved on the outside of the sealing cover, and a lower outer cover that is fixed on the bottle mouth when the bottle cap is opened is sleeved on the outside of the lower side wall of the wine pouring spout.
[0011] The utility model discloses a no material silk combined type anti -fake bottle cap adopts the combined structure, and the main part is formed by the sealing cover, spiral cover, wine pouring nozzle assembly, and the bottle cap does not produce the broken material silk material end when opening, and the cleanliness is not affected when liquid pours out, the sealing cover is clamped into the limiting slot of spiral cover after the bottle cap opens, when the bottle cap is screwed again to the bottle mouth, spiral cover and upper outer cover can not return to the position of bottle cap not opening, the position of spiral cover and upper outer cover is improved after the bottle cap is screwed, can judge whether the bottle cap is opened, plays the anti -fake effect.
