Detailed Description

In order to explain the technical solution of the present invention more clearly, the present invention is further explained below by the accompanying drawings and examples.

Example 1:

as shown in figures 1, 2, 3, 5, 6.

The composite inner liner of the bottle cap comprises a plastic inner liner 3 and a metal anti-prying ring 4.

The metal anti-prying ring 4 is tubular in shape, two obliquely upward-pointing reverse buckles 41 are punched inwards on the side surface of the metal anti-prying ring, and two turnover lugs 42 are turned outwards at the bottom edge of the metal anti-prying ring.

The upper part of the plastic inner liner 3 is provided with a bottle mouth 31, the outer side of the bottle mouth 31 is provided with a bottle mouth thread 32, a buckling groove 33 is arranged below the bottle mouth thread 32, an inner liner outer anti-rotation rib 34 is arranged below the buckling groove 33, and an inner liner inner anti-rotation rib 35 is arranged at the lower part of the inner side.

Although the anti-rotation ribs 35 in the lining can also play a certain role in stopping the metal anti-prying ring 4 above the lining, the reliability is poor because the contact surface is small. In order to enhance the reliability of the combination of the metal anti-prying ring 4 and the plastic lining 3, the plastic lining 3 is provided with a retaining buckle 36 at the position corresponding to the turnover lug 42, and the retaining buckle 36 is abutted against and buckled below the turnover lug 42.

The metal anti-prying ring 4 is placed into a cavity of an injection mold in advance before the plastic lining 3 is injected, and the metal anti-prying ring and the plastic lining are connected into a whole when the injection molding is finished.

And integrally assembling the composite lining with the bottle mouth plug 51, the inner plug 52, the outer lower cover 61, the outer upper cover 62 and the like to manufacture the complete bottle cap.

The bottle 1 corresponding to said cap is generally made of glass or ceramic material. The bottle neck 2 is provided with: a bottleneck anti-rotation rib 22 and a locking hoop 21.

When the bottle cap is sealed, the bottle cap is pressed on the bottle neck 2, the reverse buckle 41 of the metal anti-prying ring 4 slides over the bottle neck locking hoop 21 and is buckled below the bottle neck locking hoop 21, and the bottle cap cannot be pulled out. The rotation of the bottle cap is limited by the inner liner rotation-preventing rib 35 of the plastic inner liner 3 and the bottleneck rotation-preventing rib 22, and the bottle cap is fixed on the bottleneck 2 and can not be pulled up or rotated relative to the bottleneck 2.

When the bottleneck locking hoop 21 is large in size, the metal anti-prying ring 4 only receives large reaction force from the plastic lining 3 and the outer lower cover 61 at the turnover lug 42, and the rest edges have large elastic deformation relative to the whole turn-ups, so that the pressure on the bottleneck locking hoop 21 can be reduced, and the bottleneck damage is reduced.
