The technical scheme for solving the technical problems is as follows:
the utility model provides a bottle cap, includes inner cup and enclosing cover, the enclosing cover is established the periphery of inner cup, the upper end inboard of enclosing cover is connected on the inner cup lateral surface, the enclosing cover with leave the clearance of precession bottleneck between the inner cup, be equipped with the sealing ring on the inboard top surface of enclosing cover, the medial surface circumference of enclosing cover is equipped with the screw thread, be equipped with the arch on the lateral surface of inner cup.
On the basis of the technical scheme, in order to achieve the convenience of use and the stability of equipment, the utility model can also make the following improvements on the technical scheme:
furthermore, the cross section of the sealing ring is in an inverted triangle shape, and the inverted triangle-shaped sealing ring can be better pressed on the bottle mouth.
Further, the sealing ring comprises a first sealing ring and a second sealing ring, the first sealing ring is close to the inner cover, two sealing rings are arranged, and therefore the sealing effect is better.
Furthermore, the cross sectional area of the second sealing ring is larger than that of the first sealing ring, so that the sealing effect is improved.
Furthermore, the bulge is arranged below the joint of the outer cover and the inner cover and is in contact sealing with the inner side surface of the bottle mouth.
Further, protruding edge inner cup periphery circumference sets up, improves sealed effect.
The utility model also discloses a bottle mouth sealing structure, wherein the bottle mouth is sealed by the bottle cap.
Further, the bottom end of the first sealing ring is in contact with the upper end face of the bottle mouth.
Further, the side face, facing the inner cover, of the second sealing ring is in contact with the outer side of the upper end of the bottle mouth.
Furthermore, the inner side of the bottle mouth is provided with an annular groove corresponding to the bulge, the bulge is matched with the groove, and the bulge is tightly matched with the groove, so that the sealing effect is improved.
The utility model has the advantages that: seal through setting up protruding and bottleneck medial surface contact, seal through the end face contact who sets up sealing ring and bottleneck, multiple sealed improvement is sealed, need not the gasket and can realize that the bottleneck is sealed, and is sealed effectual moreover, fine solution because sealed effectual and the condition of the bottleneck weeping that leads to.
