Embodiment Construction

[0017] figure 1 It is a push-type sealing device: as shown by the arrow, the top of the cup cover 2 has an opening 14 with a large aperture in the upper half and a small aperture in the lower half. The upper half (that is, the upper half of the opening 14 ) with the sealing ring 7 at the bottom and the middle column 6 is covered with the "I" shaped pressing block 3 with the spring 4 placed in the opening 14 . Under normal circumstances, due to the tension of the spring 4, the sealing ring 7 is lifted up to block the bottom end of the opening 14. The top of the pressing block 3 is equal to or slightly higher than the top of the cup cover 2 . For smoother air intake, an air intake groove 8 is arranged on the central pillar 6 .

[0018] Working principle: When people are making tea, the cup lid 2 is tightly screwed on the cup (the cup has no technical features, which are omitted in the figure). As the boiling water in the cup cools down, the volume of the water shrinks, and a s...

Abstract

The invention provides a cup cover of a tea cup having a screwed cover and being easy to open. For the cup cover, an air inlet hole is arranged in the cup cover, under the normal state, the air inlethole is plugged by a plugging device, and the plugging device escapes from the air inlet hole under the effect of external force. A user only needs to press down a pressing block, a plugging ring thenescapes from a hole, air flow enters the cup along a gap between a center pillar and the hole, or the air flow also can smoothly enter the cup along an air inlet groove, then the differential pressure of the inside and outside of the cup is eliminated, pressure is eliminated, and at the time, after being slightly screwed, the cup cover is opened. With the technical scheme, the life trouble that after tea is made, the cup cover can not be opened due to sucking is eliminated, in addition, the structure is simple, nearly no cost is increased, thus a user is facilitated, and the competitive powerof the cup is increased.

Description

technical field [0001] The invention relates to a teacup with a twisted lid for drinking water and making tea, in particular to an easy-to-open teacup with a twisted lid and a cup cover. Background technique [0002] As we all know, brewing tea requires boiling water. People usually all can tighten cup cover after making tea, especially the teacup that goes out to carry. But when the tea in the cup is gradually cooled to drinkable, it is found that it is difficult to unscrew the cup cover. This phenomenon has puzzled people for a long time and brought inconvenience to drinking tea. [0003] The applicant found that boiling water has a small density and a large volume. When boiling water is poured into the teacup and the lid is tightened, as the water temperature cools, the volume shrinks and the volume of the cavity in the cup increases. Because the air mass remains unchanged and the volume of the cavity increases, the air inside the cup is thinner than the outside, and t...
