Description

A bottle cap with a movable sealing ring

technical field

The utility model relates to a bottle cap, in particular to a bottle cap with a movable sealing ring.

Background technique

The bottom of the bottle cap of existing general bottle is all provided with sealing ring, and when bottle cap is tightened, sealing ring is pressed on the bottleneck, guarantees that article in the bottle especially liquid can not leak out. When tightening the bottle cap, the sealing ring rotates with the bottle cap during the process from the sealing ring contacting the bottle mouth to the pressing process, which is easy to be damaged by the bottle mouth, especially when the smoothness of the bottle mouth is not smooth enough, it will cause the deformation of the contact between the sealing ring and the bottle mouth Damaged, affecting the sealing effect. For frequently used water cups, after repeated use, the probability of leakage gradually increases.

Utility model content

Aiming at the above-mentioned prior art, the technical problem to be solved by the utility model is to provide a bottle cap with a movable sealing ring.

The technical solution provided by the utility model is: a bottle cap with a movable sealing ring, including a bottle cap and a sealing ring, which is characterized in that: a sealing groove is arranged on the inner wall of the bottle cap opening, and a sealing ring is arranged in the sealing groove; The sealing ring base is hard glue, and the contact surface between the sealing ring and the bottle body is coated with soft glue; a protrusion is arranged in the sealing groove, and an annular groove is arranged on the corresponding sealing ring. The object is matched with the groove, and the protrusion can slide along the groove.

As a further improvement, the top of the sealing ring is also coated with soft glue.

As a further improvement, the sealing ring is provided with a handle.

As a further improvement, the protrusions in the sealing groove are closed annular protrusions, or discontinuous protrusions distributed along the ring.

The beneficial effect of the utility model is that, after the sealing ring contacts the bottle body, there is basically no relative rotation between the two, which avoids wear and damage of the sealing ring and ensures the sealing effect.

detailed description

As shown in Figures 1 to 2, the utility model can conveniently disassemble the bottle cap of the sealing ring, including the bottle cap 2, and the inner wall of the bottle cap 2 is provided with a sealing groove 3, and the sealing groove 3 is in an inverted L shape. There is a protrusion 31 integrally formed with the bottle cap on the long side of the shape, and the axial section of the protrusion 31 is a rectangle with rounded corners. The protrusion 31 can be an annular band around the inner wall of the sealing groove 3, or it can be several discontinuous protrusions 31 distributed along the ring, and the protrusion 31 corresponds to the groove 41 on the sealing ring 4. Cooperate with the sealing ring 4 and play a positioning role to prevent the sealing ring 4 from dislocation and falling off. The sealing ring 4 is a ring, and its substrate is hard plastic, and the surface of the substrate where the sealing ring 4 is in contact with the bottle body 1 is covered with a layer of soft rubber, such as silica gel. Of course, the top of the sealing ring 4 can also be coated with soft glue to increase the sealing effect. An annular groove 41 is opened on the outer surface of the sealing ring 4, and the groove 41 matches the protrusion 31 on the sealing groove 3, and is slightly larger than the cross section of the protrusion 31, so that when the sealing ring 4 is packed into the sealing groove At 3 o'clock, the protrusion 31 is inserted into the groove 41, and there is a gap between the two. At the same time, because the base of the sealing ring 4 is hard plastic, it will not be deformed excessively, so that the sealing ring 4 can be placed on the sealing groove 3. Slide on the protrusion 31. The bottom of bottle cap 2 also has an inner cover, and the inner cover outer ring has thread, and the bottle mouth inboard of bottle body 1 has the screw thread that matches with bottle cap inner cover thread. The mouth of the bottle body 1 has a horn-like slope. When the bottle cap 2 is put on the bottle mouth of the bottle body 1, during the tightening process, when the sealing ring 4 contacts the bottle body 1 and deforms, there is less relative rotation between the sealing ring 4 and the bottle body 1, and the sealing ring 4 Basically no damage will occur. In order to facilitate the disassembly of the sealing ring 4, a handle 5 can be integrally formed on the sealing ring 4, and the handle 5 stretches out from the bottle cap 2. As long as the handle 5 is pulled, the sealing ring 4 can be directly pulled out from the bottle cap.

Above, the embodiments of the utility model have been described in detail in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments, and within the scope of knowledge of those of ordinary skill in the art, it is also possible to Make various changes.
