Description

Automatic open and close protective lid

The utility model relates to a kind of automatic switch over cap, and the lid of bottle, jar and the teapot mouth of dress liquid, powder is used in suitable the work.

At present, because the raising of standard of living, people also improve the requirement of the preservation quality of varieties of food items, and general natural products is subject to factors such as temperature, weather and can't preserves for a long time, for this reason, need some bottles, jar to come article-containing, improving the holding time, during general storaging liquid, all use bottle, jar come splendid attire, one is anti-pollution, and two come also can conveniently utilize.Usually install a bottle cap additional in the exit of bottle, jar, enter in the bottle to prevent foreign matter.The teapot mouth is that dust protection enters in addition, also adds a cover of dust.The shortcoming of these bottle caps: 1, generally these bottle caps be equiped with two kinds of methods, a kind of is after utilizing the sheetmetal punch forming, directly in the mode that is pressed into bottle, cover is combined with bottle, jar again; Another kind be bottle, jar the exit outside thread is set, make it and female bottle cap is set equally combines; The former mode that is pressed into combination must utilize bottle cap opener that bottle cap is pulled up in the time of will opening bottle cap, will make the bottle cap distortion of metal material like this, can't use again; The latter utilizes the mode of screw thread combination, makes bottle cap distortion though be unlikely, however every use once must open, close once, use bothers, and the bottle cap that is taken off extremely takes up space, moreover bottle cap is easy to land and makes dirty or lose during use; 2, bottle cap mostly adopts metal material to make, and uses once and must open once, is easy to scratch hand; 3, the cover of dust of spout of a teapot and spout of a teapot articulate, and toppling over the tea time influences flow, have the people then simply to take down cover of dust and serve the tea, forget again with Bi Youhui to cover, in addition, do not serve the tea, to certain angle even do not take down lid, this lid can not restore, and also handy hand sets right, and uses very inconvenient.

The purpose of this utility model be a kind of lid of design with bottle, jar or the outlet of teapot combine can be when bottle, jar or teapot be toppled over or are kept flat the energy automatic switch do not influence bottle in article pour out the automatic switch over cap of flow.

The purpose of this utility model is achieved in that the utility model is made up of lid, pivoted pole, clump weight and cover plate, wherein:

A, lid is a long ellipsoid, in the one side open-work that runs through is set, the screw thread or the inlay card ring that match with bottleneck in the setting of open-work inner edge, at its opposite side a circular groove is set, the height of this circular groove is higher than the position of open-work, a ccontaining mobilizable clump weight in circular groove, between circular groove and open-work, offer a short slot, a ccontaining mobilizable pivoted pole in the short slot; Cover plate is made up of portable plate and adapter plate, and portable plate is located at the opposite position of open-work; Adapter plate then is fixed on the circular groove, a pivot joint block is extended at a position at the bottom surface of adapter plate periphery downwards, place the front end of the pivoted pole in the short slot to be fixed in the bottom surface of portable plate, the terminal clump weight interior with placing circular groove fixed, and the place, middle part of pivoted pole extends upward a lug that cooperates with pivot joint block;

B omits cap portion, and cover plate is made up of a portable plate, and pivoted pole is made up of an extended articulated section, portable plate rear end and a pole, fixes a clump weight at the other end of pole.

Over cap of the present utility model needn't directly be stirred with hand in use; as long as bottle is toppled over can directly be opened; keeping flat bottle can directly close; easy to use and safety; and lid can not break away from bottle; needn't worry to land loss, the difform bottle of suitable all kinds of carrying liquids, powder, jar and kettle use.

Details are as follows to structure of the present utility model with reference to the accompanying drawings below:
