Abstract
The present invention relates to the gas-tight storage container that under normal pressure, uses.It comprises container body, and seal cover cap (door) it is characterized in that: further comprising air pressure adjustment mechanism.This mechanism can be air bag or barrier film, also can be the combination of air bottle, air pump, blow off valve, baroceptor and controller.When draught head occurring inside and outside the container, the air pressure adjustment mechanism action changes the air pressure of internal tank gas, to reduce or eliminate draught head, keeps the air-tightness of container.It is simple for structure, and airtight effect is good, helps unlatching, " locked in " operation.
Description
The present invention relates to gas-tight storage container.Especially refer to the gas-tight storage container under condition of normal pressure, can repeatedly open and close.
The existing normal pressure gas-tight storage container that can repeatedly open and close, for obtaining good air tightness, all be to improve aspect the gastight material of airtight cover (or door) or the airtight construction, the airtight effect of the simple or gas-tight storage container that cost is low of airtight construction often, particularly the airtight effect of repeatedly opening after using is not ideal enough, owing to gas leakage influences guaranteeing the quality of the article of storing; And the high gas-tight storage container of airtight construction complexity or cost, unlatching, osed top operation more complicated or damage easily are not easy to generally use.Through experimental observation, under identical airtight construction and airtight material strips part, the air-tightness of container is directly relevant with exterior draught head with internal tank, and draught head is bigger, and air-tightness is poorer.
The present invention aims to provide and can reduce or eliminate internal tank and exterior draught head, thereby effectively keeps the bubble-tight gas-tight storage container that can repeatedly open and close.
Technical essential of the present invention is: the air pressure adjustment mechanism of installing the scalable internal tank gas pressure on the gas-tight container that includes container body and airtight cover (or door) additional.Air pressure adjustment mechanism can be air bag or barrier film, the connection container inside, a side of air bag or barrier film, another connection container outside, side; Air pressure adjustment mechanism also can include air bottle, air pump, blow off valve, baroceptor and controller; The inside of the input end connection container of air pump, mouth is communicated with air bottle, and air bottle also is communicated with an end of blow off valve, the inside of the other end connection container of blow off valve, controller and baroceptor, air pump and blow off valve electrically connect respectively.
For the air pressure adjustment mechanism of air bag or barrier film form, when draught head occurring inside and outside the described container, air bag or barrier film distortion change the volume of internal tank gas and pressure, thereby have reduced or eliminated draught head.
For the air pressure adjustment mechanism that forms by air bottle, air pump, blow off valve, baroceptor and controller, baroceptor passes to controller with the draught head information inside and outside the container, controller control air pump pumps into air bottle or control exhaust valve opening with the portion gas in the container, gas in the air bottle is put into container, to reduce or eliminate draught head, keeping container air pressure close is that its internal gas does not exchange with the external world.
Advantage of the present invention is simple for structure, and airtight effect is good, helps unlatching, " locked in " operation.
The present invention is further elaborated below in conjunction with embodiment and accompanying drawing:
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the structural representation of another embodiment of the present invention.
Fig. 3 is the structural representation of another embodiment of the present invention.
Fig. 4 is the structural representation of four embodiment of the invention.
Embodiment illustrated in fig. 1 is an air-tight bottle, and there is outside thread in the oral area outside of bottle 1, and there is corresponding negative thread bottle cap 2 oral area inboards.Clamped seal ring 3 between the convex shoulder 6 of the annular of bottle cap 2 inboards and the oral area of bottle 1.Barrier film 4 is made of one structure with seal ring 3, makes with latex.The thickness of barrier film 4 is much smaller than the thickness of seal ring 3.Breather hole 5 is arranged at bottle cap 2 tops.Form an empty chamber between bottle cap 2 inboard convex shoulders 6 and the end face.
After bottle cap 2 screwed, bottle 1 inboard was hermetic closed by seal ring 3 and barrier film 4.When wherein gaseous tension during less than ambient pressure, barrier film 4 concaves; And when wherein gaseous tension during greater than ambient pressure, barrier film 4 is to evagination; The volume and the pressure of bottle 1 internal gas has been adjusted in the distortion of barrier film 4, but actv. keeps the air-tightness of whole air-tight bottle.Obviously, when this bottle store medication or other article, open the same simple and convenient with general bottle with sealing.
Fig. 2 illustrates the sectional structure in an airtight storehouse, and the inside upper part of storehouse body 7 has support 10, and there is door 8 side, and door 8 is provided with O-ring seal 9, and suitable locking mechanism spare (not shown).The air bag 11 that rubber or plastic sheeting are made is placed on the support 10.Air bag 11 has breather pipe 12 to be encapsulated on the sidewall of storehouse body 7, and it is extraneous that air bag 11 medial surfaces are communicated with, and its lateral surface is communicated with in the storehouse.
When the storehouse internal gas pressure is lower than ambient pressure, air bag 11 inflations; Otherwise air bag 11 loses heart and dwindles; Thereby the surge bunker internal gas pressure reaches maintenance air tight purpose.If install blow off valve and air supply plant additional at the external side end of breather pipe 12, as air pump or air bottle, and baroceptor and control setup are installed inside and outside the storehouse, but automatic guidance storehouse inner and outer air pressure strict conformance then.Door 8 adopts relatively simple for structure, and the airtight construction of conveniently opening and closing still can reach the good air tightness requirement.
Fig. 3 illustrates the structure of an airtight cabinet.The rear side of cabinet 13 has the air bag 14 of air extractor vent 15 diaphragm for passageway formulas.Make the medial surface of air bag 14 be communicated with in the cabinet and the lateral surface connection external world.Cabinet 13 tops are cabinet lid 16 and seal ring 17, and hinge and chucking attacker connect cabinet 13 and cabinet lid 16, make it to constitute an integral body.
When cabinet internal gas pressure during greater than ambient pressure, air bag 14 is forced to expand; Otherwise air bag 14 dwindles.The cabinet internal gas pressure is able to and extraneous balance.
Embodiment shown in Fig. 4 is airtight storehouse, and the door 8 with O-ring seal 9 has been installed on the storehouse body 7, and storehouse body 7 is communicated with the input end of air pump 18 and an end of blow off valve 19 through the breather pipe 17 of three-port structure.The other end of the mouth of air pump 18 and blow off valve 19 is communicated with air bottle 21 by another three-way pipe 20.The sidewall installing gas pressure sensor 22 of storehouse body 7.Gas pressure sensor 22 and controller 23 link.Controller 23 also connects air pump 18 and blow off valve 19.When storehouse internal gas pressure during greater than the external world, 18 work of controller 23 control air pumps pump into air bottle 21 with the portion gas in the storehouse; Otherwise control blow off valve 19 is opened, in the gas loopback is put in storage in the air bottle 21; And after the difference of pressure elimination, air pump 18 and blow off valve 19 are in closed condition.
Connecting of controller 23 and air pump 18, blow off valve 19, gas pressure sensor 22 for electrically connecting.
Remove breather pipe 17, with air pump 18, it also is feasible in the storehouse that blow off valve 19, three-way pipe 20 and air bottle 21 are installed in.
