Abstract
A cup lid with air pressure balancing function for the air tight cup such as travel cup or insulating cup features the use of screw valve, spring acting on valve and pash button connected to valve. Its advantages are simple structure and low cost.
Description
The present invention relates to the inside and outside air pressure balance technology of bowl cover.
At present, all kinds of traveling glasses and the thermos cup sold on the market, in order to make its water-tight and raising heat-insulating property when being inverted, the air-tightness of its cup and bowl cover is generally all very high.When having contained boiling water in the cup and bowl cover covered, the inside and outside air pressure of bowl cover is the same, but, after the boiling water in the cup cools off in time, air pressure in the bowl cover just changes, the temperature fall of boiling water must be low more, and the air pressure in the cup also will become low more thereupon, and a barometric pressure outer with cup formed difference of pressure.When people's desire was opened bowl cover drinking-water, the strength that often needs to cost a lot of money just can be taken off bowl cover, and the little child of strength just can't open bowl cover at all.This has brought very big inconvenience to use.Can therefore, make above-mentioned traveling glass and thermos cup both to have had very high air-tightness, can take off the bowl cover that is enclosed on the cup easily at any time again, be that users wish the problem that solves.
The objective of the invention is to solve the problems referred to above by a kind of air-pressure balancing device of simply and easily going of on bowl cover, establishing.
The present invention is achieved in that
Structurally constitute by screw valve and the spring that acts on it at least; The pine of spring with tightly be to regulate by the turn of button on the screw valve; Screw valve have drawn from plastics or rustless metal; Its using method can have manual or automatic two kinds:
Manual method: the unlatching of screw valve is finished by pressing the button;
Automatic method: the unlatching of screw valve is to finish by the draught head in the outside in the cup (a cup external pressure is higher than in the cup);
The present invention's characteristics compared with the prior art:
Because the present invention has the air pressure balance function, this has created condition with regard to the bowl cover that at any time can both easily and reliably open traveling glass and thermos cup one class cup tool for the present invention in using.
Figure has illustrated an enforcement of the present invention.
The 1-bowl cover; The 2-button; The 3-spring; 4-plastics or corrosion-resistant steel sealed screw valve; The 5-cup.
Figure has illustrated:
Button " 2 " links to each other by screw thread with sealed screw valve " 4 ", and during button " 2 " dextrorotation, spring " 3 " is compacted, and when left-handed, spring " 3 " is loose; Should slightly exceed bowl cover " 1 " end face after button " 2 " is installed is appropriate for about 5 millimeters.
When the bottom surface of the top cap of sealed screw valve " 4 " and bowl cover " 1 " relies on the elastic force of spring " 3 " that they are adjacent to mutually, will play the sealing function of isolating outside gas in the cup " 5 ".
When sealed screw valve " 4 " when moving down, the air in cup " 5 " outside will be under the ordering about of difference of pressure, penetrate into cup " 5 " inboard the slit from screw valve " 4 " and being connected of bowl cover " 1 " soon, make that the air pressure in the outside keeps balance in the cup " 5 ".
First kind of using method of the present invention:
With the flexible adjustment of spring " 3 " to: make cup " 5 " after covering bowl cover " 1 ", wherein a small amount of boiling water of Shenging drops to Celsius 0 when spending from 100, screw valve " 4 " just can be driven and move down by cup " 5 " external and internal pressure difference, makes that pressure and the pressure outside the cup " 5 " in the cup " 5 " keeps balance.
In the process of using, if dropping to, the boiling water temperature in the cup can not make screw valve " 4 " when moving down, that is: water temperature is higher than 0 when spending, and cup " 5 " and its bowl cover " 1 " are in good sealing state all the time, if need drink water, directly opening bowl cover " 1 " can be gruelling, at this moment, only need to place on the bowl cover " 1 " button " 2 " flicking once, screw valve " 4 " promptly moves down, the inside and outside air pressure of cup " 5 " tends to balance very soon, just can open bowl cover " 1 " easily and drink water.
Second kind of using method of the present invention:
On the elastic foundation of the spring " 3 " of above-mentioned first kind of using method, left-handed button " 2 ", make that spring " 3 " is loose, loosely descend about 10 when spending to water temperature, screw valve " 4 " will be driven and move down automatically by the atmospheric pressure difference in the outside in the cup " 5 ", during this, when the every decline 10 of the water in the cup " 5 " is spent, screw valve " 4 " will self-opening make the outside in the cup " 5 " equilibrium of pressure once, under such situation, in the time of need drinking water, just open bowl cover " 1 " at any time, just may use some power slightly sometimes in the opening process.
If it is more painstaking that sensation is opened bowl cover " 1 ", so, above-mentioned " 10 degree " temperature difference can be dwindled example again: 5 degree.In a word, the present invention is to allow and can regulate by rotary knob " 2 " because of the people changes places structurally, reaches till user's satisfaction of each bowl cover " 1 ".
Enforcement of the present invention mainly is to set up the air pressure balance functional device on existing bowl cover " 1 ", and its enforcement difficulty and cost increase are all little.
Claims (4)
1. a bowl cover and using method thereof that the air pressure balance functional device is set, A. structurally is made of screw valve " 4 " and the spring " 3 " that acts on it at least;
2. a bowl cover and using method thereof that the air pressure balance functional device is set, A. structurally is made of screw valve " 4 " and the spring " 3 " that acts on it at least; B. structurally the pine of spring " 3 " with tightly be to regulate by the turn of button " 2 " on screw valve " 4 ";
3. a bowl cover and using method thereof that the air pressure balance functional device is set, A. structurally is made of screw valve " 4 " and the spring " 3 " that acts on it at least; B. structurally the pine of spring " 3 " with tightly be that turn by button " 2 " is regulated; C. using method: manually method or method automatically,
Manual method: the unlatching of screw valve " 4 " is finished by pressing the button " 2 ";
Automatic method: the unlatching of screw valve " 4 " is by finishing by the draught head in the outside in the cup " 5 ";
4. according to claim 1,2 and 3 described a kind of bowl cover and using method thereof that the air pressure balance functional device is set, it is characterized in that: described screw valve " 4 ", its have drawn from plastics or rustless metal.
