EXAMPLE five

In the above embodiment, the coupling member 3 merely longitudinally couples the mouth 1 to the neck to prevent the vertical separation from the neck, but the rotation of the mouth 1 and the coupling member 3 in the horizontal direction with respect to the neck 4 is not limited. When a user rotates the pull rod 2 with one hand, if the connecting piece 3 is not stabilized with the other hand to keep relative static with the bottle neck 4, it cannot be guaranteed that the bottle mouth 1 will not rotate synchronously when the pull rod 2 rotates. If the bottle mouth 1 and the pull rod 2 rotate synchronously, the pull rod liquid outlet 23 and the inner cylinder liquid outlet 12 cannot form left-right dislocation to close the inner cylinder liquid outlet 12, and secondary sealing cannot be finished. In other words, to ensure that the secondary seal is achieved, the tie rod 2 must be rotated by one hand while the connector 3 must be stabilized by the other hand or otherwise. For most consumers, they are more accustomed to holding the bottle (rather than the connector) with one hand and operating the cap with the other hand, which requires the neck 4 to be able to limit the rotation of the connector 3 and the mouth 1 in the horizontal direction.

As shown in fig. 12, 13, 15.

To achieve the above purpose, the present embodiment is based on any of the above embodiments, and the inner anti-rotation rib 32 is disposed on the inner side of the connecting member 3, and the corresponding bottleneck anti-rotation rib 42 is disposed on the outer side of the bottleneck 4. After the retaining neck finish assembly presses the bottle neck 4, the inner anti-rotation rib 32 of the connecting piece 3 is limited by the bottle neck anti-rotation rib 42 outside the bottle neck 4, and the connecting piece 3 of the retaining neck finish assembly can not be pulled up or rotated relative to the bottle neck 4. Under the structure, if secondary sealing is needed, one hand can hold the bottle, the other hand can rotate the pull rod 2, and the bottle mouth 1 cannot synchronously rotate along with the pull rod 2.

For simplifying the description, the embodiment is only shown in the drawings by adding the anti-rotation rib to the anti-rotation bottle mouth component in the third embodiment, and the same description is omitted for the other embodiments.

EXAMPLE six

In the above embodiments, the bottle mouth 1 and the connecting member 3 are made of plastic material, and are fixedly connected with each other.

The connecting member 3 of the present invention is not limited to the plastic member with the inner buckle 31, and wraps the bottle mouth 1 with the metal pipe (such as aluminum material), and then connects it to the bottle neck through the rolling edge, which is also a common connecting mode in the prior art, as shown in fig. 16.

Before the non-return bottle mouth component of the embodiment is assembled with the bottle neck 4, the connecting piece 3 is wrapped on the outer side of the bottom edge of the bottle mouth 1, the upper part of the connecting piece is provided with an upper folding edge 33 which is covered on the upper part of the bottom edge of the bottle mouth 1, and the connecting piece 3 does not limit the rotation of the bottle mouth 1 and does not limit the downward movement of the bottle mouth 1;

when the anti-return bottle mouth component of the embodiment is assembled with the bottle neck 4, the lower part of the connecting piece 3 is also folded (34 in fig. 16) and is wrapped below the bottle neck locking hoop 41, so that the bottle mouth 1 cannot move relative to the bottle neck in the longitudinal direction; further, if the connector 3 wraps the mouth 1 and neck lock band 41 tightly enough to provide sufficient resistance to rotation of the pull rod 2, the mouth 1 cannot rotate relative to the mouth. No matter which of the above situations, it only affects whether the other hand holds the bottle or the bottle mouth when the consumer opens the bottle, but does not affect the technical problem to be solved by the utility model: opening prompt and secondary sealing.
