Anti-blocking anti-backflow lining assembly

Technical Field

The utility model relates to a bottle lid technical field especially relates to a bottle lid inside lining subassembly with anti-sticking is dead and prevent flowing backward structure.

Background

Among the counterfeiters of a plurality of wine products in the market, the wine bottle is filled and counterfeited by using the empty wine bottles consumed and used by the original manufacturer, and occupies a considerable proportion. Firstly, the method does not need to make wine bottles again, can make the wine bottles by recycling the wine bottles in the market, and has extremely low cost; secondly, because the wine bottles are original factory products, the consumers can not distinguish the true from the false from the appearance alone.

Aiming at the counterfeiting method, anti-counterfeiting bottle caps with anti-backflow structures are released by a plurality of wine manufacturers so as to prevent and eliminate the counterfeiting products. The anti-counterfeiting bottle caps are characterized in that the wine in the bottle can be poured out normally, but the wine is difficult to pour in from the outside to the inside without damaging the bottle caps. Among them, the most widely used is the glass bead anti-backflow bottle cap. The specific method of the bottle cap comprises the following steps: a glass ball is arranged between the mouth of the bottle cap and the inner plug. When the bottle body is upright, the glass ball is blocked on the wine outlet of the inner plug due to the action of gravity. When the wine needs to be poured, the bottle body is inverted, the glass ball leaves the inner plug wine outlet under the action of gravity, and the wine body can flow out of the inner plug wine outlet and is poured out of the bottle through the bottle mouth. After the wine is poured, the bottle body is placed in the forward direction again, and the glass ball seals the wine outlet again under the action of gravity. At this time, the wine body cannot be poured into the wine bottle by the conventional method. However, if a counterfeiter turns the bottle upside down and the glass ball leaves the wine outlet of the inner plug, the injection needle is inserted into the vicinity of the wine outlet of the inner plug along the inner side of the bottle mouth to prevent the glass ball from resetting, and then the bottle is filled with the counterfeit wine through the injection needle. In addition, the glass ball is blocked at the bottom opening of the inner plug, so that the wine in the bottle can not be poured out.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example one

As shown in fig. 1 and 2. The utility model provides a dead inside lining subassembly of preventing flowing backward of anti-sticking, includes inside lining 1, bottleneck 2, inside lining 1 and bottleneck 2 fixed connection. The inner side of the liner 1 is provided with an inverted buckle 11 and a liner anti-rotation rib 12.

The bottle neck 2 is provided with a backflow prevention cavity 3 on the inner side, and the backflow prevention cavity 3 is composed of two bilaterally symmetrical half cavities. The side surface of the backflow-preventing cavity 3 is provided with a side wine outlet 31, and the bottom of the backflow-preventing cavity is provided with a wine inlet 32. The inner side of the backflow-preventing cavity 3 is provided with a conical top 33.

The backflow prevention cavity 3 is internally provided with a movable block 4, and the movable block 4 is conical. The conical angle of the movable block 4 is less than or equal to that of the conical top 33. The diameter of the bottom surface of the movable block 4 is larger than that of the wine inlet 32 at the bottom of the backflow prevention cavity 3. The lower part of the movable block 4 is connected with a guiding reset piece 41. The guiding and returning element 41 is conical and the direction of the cone is opposite to the direction of the movable blocking piece 4. The total height of the movable block 4 and the guiding and resetting piece 41 is larger than the inner height of the anti-backflow cavity 3. The diameter of the bottom surface of the guiding and resetting piece 41 is smaller than that of the wine inlet 32.

As shown in fig. 6. And the corresponding bottleneck 5 of the utility model is provided with a locking hoop 51 and a bottleneck anti-rotation rib 52. When the anti-blocking anti-backflow lining component is assembled on the bottleneck 5, the back-off 11 is buckled below the locking hoop 51 to prevent the lining 1 from being pulled out; at the same time, the liner rotation preventing rib 12 is stopped by the neck rotation preventing rib 52, so that the liner 1 cannot rotate relative to the neck 5. The anti-blocking anti-backflow lining component is fixedly connected with the bottleneck 5 and can not be pulled up or rotated.

When the wine bottle is placed in the forward direction, the movable blocking block 4 blocks the wine inlet 32 at the bottom of the anti-backflow cavity 3, and wine cannot be poured into the bottle from the upper part. When pouring wine, the wine bottle is inverted, the movable block 4 is separated from the wine inlet 32 under the action of gravity, and the wine body flows into the backflow preventing cavity 3 from the gap between the movable block 4 and the wine inlet 32 and then flows out of the backflow preventing cavity 3 through the side wine outlet 31. When the wine bottle is inverted, the top point of the movable block 4 is guided and limited by the conical top 33 of the anti-backflow cavity 3 and finally slides to the top point of the conical top 33 because the movable block is conical. The two conical tops are matched in structure, so that the wine bottle cannot be clamped when being erected again. And when the wine bottle is inverted, the guiding and resetting piece 41 is still positioned in the wine inlet 32, and when the wine bottle is upright again, the guiding and resetting piece 41 pulls the movable blocking block 4 back to the original position. Because the diameter of the bottom surface of the guiding and resetting piece 41 is smaller than that of the wine inlet 32, the guiding and resetting piece can not be clamped in the wine inlet 32 during wine pouring and returning.

Example two

The guiding and resetting piece 41 has the function of preventing the movable block 4 from returning to the original position when the wine bottle is reset. But its shape is not limited to the conical shape described in the first embodiment. As long as it is spaced from the wine inlet 32, it will not be jammed during pouring and returning, and when pouring, it is ensured that a part of the wine is still left in the wine inlet 32, and other shapes, such as a cylinder, can achieve the same technical effect. As shown in fig. 3 and 4.

The structure of the present embodiment is the same as that of the first embodiment except that the guiding and returning member 41 is cylindrical.
