As preferably, described seal ring is provided with annular seal groove, and the end face of the open end of described bottle cap is tightly connected with described seal groove.Can improve the sealing effectiveness between bottle cap and the bottleneck.
As preferably, be provided with packing seal in the described seal groove.The processing request of bottleneck open end end face and seal ring be can reduce, comfort feature and yields that bottle cap and bottleneck add man-hour improved.
As preferably, the upper surface of the root of described clasp joint sheet is provided with otch.Play the effect that reduces the required power of clasp joint sheet upset.Be convenient to the unlatching of bottle cap.
As preferably, described otch runs through upper surface and the lower surface of the root of described clasp joint sheet.Can reduce the power of clasp joint sheet elastic recovery.In case bottle cap was unlocked, then the clasp joint sheet can not be fitted together with abutment ring effectively, and whether the user can judge easily bottle cap and be unlocked.Play better anti-theft feature.
As preferably, the roof inside face of described bottle cap is provided with first ring and the second ring, surrounds the positioning groove for accommodating bottleneck apical margin between the roof of first ring, the second ring and bottle cap.When the bottle cap lid is located on the bottleneck, the apical margin of bottleneck is contained in the positioning groove, play the effect that bottleneck is reinforced, in the thinner situation of bottleneck wall thickness, also can firmly fix the bottle cap obscission that can produce the bottleneck distortion together and or not cause between bottle cap and the bottleneck, can save the consumption of bottleneck material.
As preferably, the inside face of described bottleneck is tightly connected with positioning groove.Two road Seal Design are guaranteed bottle interior space with extraneous isolation, and sealing is reliable.
The utlity model has following advantage, sealing surface is designed on the open end of bottle cap, the formed inner chamber in the position that is threaded of bottle cap and bottleneck is with extraneous isolation, so this inner chamber can contaminated and breed bacteria in accumulating way, can guarantee that object can be not contaminated in the bottle, mouth directly contacts bottleneck can not endanger health of human body, safety and sanitation yet.
