Abstract
The utility model relates to a cup lid, in particular to a negative pressure prevention cup lid. The negative pressure prevention cup lid is composed of a cup lid body and a sealing ring, wherein the sealing ring is arranged inside the cup lid body, a plurality of cavitation bubbles are arranged on the circumference of the inner bore of the sealing ring at intervals, vent holes which correspond to the cavitation bubbles are arranged in the sealing ring, and the vent holes and the cavitation bubbles are communicated. The negative pressure prevention cup lid is simple in structure, low in cost, convenient to operate, capable of solving the problems that the purpose of opening the cup lid can be achieved, however, operation processes are complicated and consumers can not accept the cup lid easily, capable of effectively preventing negative pressure inside a cup from generating, reliable in performance, and safe in using.
Description
Technical field
The utility model relates to a kind of bowl cover, is specifically related to a kind of anti-negative pressure bowl cover.
Background technology
The teacup that uses in the daily life mostly disposes bowl cover, and especially thing is carried the teacup of use during the journey, and bowl cover all is to be configured in threadably on the teacup, its objective is the sealing that increases teacup.But in actual use, because the decline of tea temperature, the pressure in the cup progressively forms negative pressure less than the pressure in the external world, causes bowl cover to open difficulty.For addressing this problem, people have found out a lot of solutions, as: application number is 201010230397.5, name is called the patent of invention of " breathable teacup device ", it is to be provided with recess in the bowl cover middle part of bowl cover, be installed with the hole in the middle of the depression, T-shaped nut passes a rubber ring, pass again the middle mesopore of bowl cover, pass again a spring, the other end of spring then by T-shaped screw as baffle plate, so that the elastic force of spring acts on the rubber ring between T-shaped nut and the bowl cover all the time, to reach the purpose of sealing.At ordinary times with common teacup difference useless, run into inner air and outer air and do not circulate not cause when opening and only need press gently button, make glass internal and external pressure balance just can open easily teacup.Although this scheme can reach the purpose of open cup cover, affect the specious property of teacup, be not easy to consumers in general and accept.
Summary of the invention
The purpose of this utility model is: provide a kind of simple in structure, can effectively prevent glass anti-negative pressure bowl cover that interior negative pressure produces.
The technical solution of the utility model is:
A kind of anti-negative pressure bowl cover, it is made of bowl cover body and sealing ring, is provided with sealing ring in the bowl cover body, it is characterized in that: the interval shape is provided with a plurality of cavitys on the endoporus circumference of sealing ring, be provided with passage on the sealing ring corresponding with cavity, passage is communicated with cavity.
Be provided with otch on the described cavity.
The utility model has the advantage of
Should prevent that the negative pressure bowl cover was simple in structure, with low cost, easy to operate, although avoided prior art can reach the purpose of open cup cover, but operating process is loaded down with trivial details, be not easy to the problem that consumers in general accept, effectively prevented the generation of negative pressure in the cup, and dependable performance, use safety.
Description of drawings:
Fig. 1 is plan structure schematic diagram of the present utility model;
Fig. 2 is the structural representation of sealing ring of the present utility model;
Fig. 3 is cross section structure schematic diagram of the present utility model.
Among the figure: 1, bowl cover body, 2, sealing ring, 3, cavity, 4, passage, 5, otch.
The specific embodiment
Should be consisted of by bowl cover body 1 and sealing ring 2 by anti-negative pressure bowl cover, be provided with sealing ring 2 in the bowl cover body 1.The interval shape is provided with a plurality of cavitys 3 on the endoporus circumference of sealing ring 2, and cavity 3 tops are provided with slot-shaped otch 5.Be provided with passage 4 on the sealing ring 2 corresponding with cavity 3, passage 4 is communicated with cavity 3.
Should prevent the negative pressure bowl cover in use, after the injection boiling water covers bowl cover in cup, owing to have the slit between the internal thread on the bowl cover and the external screw thread on the rim of a cup, extraneous air can enter in the passage 4 of sealing ring 2 by this slit, and enter in the cavity 3, after the water temperature in the cup descends cooling, the cup internal pressure is less than the external world, be that cavity 3 chamber pressures are greater than the ambient pressure of cavity 3, at this moment, the otch 5 that air can strut on the cavity 3 enters in the water tumbler automatically, thereby makes the inside and outside pressure balance of water tumbler, and bowl cover can be opened freely.Otherwise when cup internal pressure during greater than ambient pressure, namely cavity 3 chamber pressures are less than the ambient pressure of cavity 3, and the cup internal pressure can be with otch 5 sealings, thereby reach the purpose (referring to accompanying drawing 1-3) that prevent the interior tea leakage of cup.
Embodiment described in the utility model only is the description that preferred embodiment of the present utility model is carried out; be not that the utility model design and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; engineers and technicians make the technical solution of the utility model in this area various distortion and improvement; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
