The utility model can be used for containing pickles, glutinous rice wine, fermented bean curd, flour paste and sweetmeat and storing medicine. The one-way valve of the utility model is precise and sensitive, and the utility model has the advantages good sealing performance, firmness, easy manufacture, low cost, convenient operation, sanitation, beautiful appearance and convenient carrying.

Description

Improved multipurpose container

The utility model belongs to the small stores field.

Present new-type pickle jar design is that altar body and altar have covered respective threaded, screw the packing ring between compacting altar body and the altar lid, play sealing function, altar covers useful nylon sleeve and makes up and form check valve, produce gas in the pickles process, the altar internal pressure is greater than the outer bar pressure of altar, the interior gas of altar makes the place up by nylon sleeve and outwards releases, and altar external body gas can't enter, but one of actual nylon and other plastic material common features---elastic restoration, passing in time progressively is reduced to original shape, makes to make the not good enough or inefficacy of sealing effectiveness up.

The purpose of this utility model provides a kind of follow-on multipurpose container.Utilization is contained in being active in one's movements and unidirectional exhaust gear that air-tightness is good on the container, to guarantee that gas pressure balancing in the container is in a predetermined value.

The utility model has adopted following structure in order to achieve the above object: comprise that top has the shell of tank that connects registration device, the material of shell of tank can be glass or pottery or rustless metal; Can be connected the container cover of locating and having check valve with shell of tank, the material of container cover can be nonpoisonous and tasteless plastics or pottery or rustless metal; Tightening seal washer, the material of tightening seal washer are nonpoisonous and tasteless rubber or plastics; Take gas port out of and have the valve gap that connects registration device, fuse with container cover and can be connected the valve body of location with above-mentioned valve gap, the valve body hollow space is a valve pocket, spring, spool are arranged in the valve pocket, make the valve opening that has that is communicated with in valve pocket and the shell of tank on container cover, the material of valve gap is plastics or metallo-; Valve body, the valve pocket material that links to each other with container cover is identical with container cover, and the material of spool is the ceramic or nonpoisonous and tasteless plastics of non-corrosive metal or glass; The form of spool can adopt needle-valve or ball valve, and the material of spring is rustless metal or nonpoisonous and tasteless elastoplast; Can cover the protective case of the check valve that links to each other with container cover, the check valve protective case is stamped the device that is connected the location with container; The material of check valve protective case is plastics or glass or metallo-.

After other part of container is finished by the designing requirement combination, when internal tank gas pressure adds spring pressure greater than the external container bar pressure, gas in the container is by valve opening, and the jack-up spool makes deflection of spring and enters valve pocket, releases gas by the air extractor duct on the valve gap that is connected the location with valve pocket again; When the gaseous tension in container equals the external container bar pressure, by the pressure of valve pocket medi-spring, the reduction of spring shape, pressure transmission spool seals valve opening again, and container is inside and outside isolated, reaches the leak free purpose; When the pressure of internal tank gas adds spring pressure less than the external container bar pressure, outside atmospheric pressure adds spring pressure and acts on spool greater than container internal pressure, and spool is against on the valve opening, and the sealing valve opening can't enter in the container extraneous gas.The mode of changing says that the irreversibility that is exactly check valve makes external container gas can't enter internal tank.

The utility model good airproof performance, precision, sensitivity, firm, easy manufacturing, low cost, easy to use, health, attractive in appearance, the transportation that is easy to carry, and be a kind of can infusion, brewage pickled, store multi-purpose container.

Below accompanying drawing is further specified:

Fig. 1 is the half-sectional view of improved type multipurpose container

Fig. 2 is the section-drawing of check valve among Fig. 1 (3)

Shell of tank (1), container cover (2), check valve (3), check valve protective case (4), tightening seal washer (5), shell of tank outside thread (6), container cover negative thread (7), valve gap (8), valve gap negative thread (9), air extractor duct (10), valve body (11), valve body outside thread (12), valve pocket (13), spring (14), spool (15), valve opening (16).

Followingly be illustrated with reference to accompanying drawing 1,2 couples of embodiment of the present utility model of accompanying drawing:

The outside thread (6) and the inboard negative thread of container cover (2) (7) of shell of tank (1) outer, top are tightened, shell of tank and container cover are closely linked, compress the tightening seal washer (5) that the shell of tank oral area is placed, make seal of vessel with outside isolated, valve gap (8) on the check valve (3) adopts valve gap negative thread (9) with valve body (11), valve body outside thread (12) form unscrews the connection that screws, to regulate the pressure that withstands on the spring (14) on the needle-valve (15) in the valve pocket (13), this needle-valve sealing valve opening (16), spring inside diameter is less than the needle-valve outside diameter, when being ball valve greater than end diameter or spool, spring inside diameter completely cuts off the circulation of the inside and outside gas of container less than the ball valve diameter.When gas differential pressure equals zero inside and outside the container, make container be in sealing state by tightening seal washer and check valve; When gaseous tension in the container during less than bar pressure, because the irreversibility of check valve work, then container is in sealing state.Example: be placed with article or medicine in the container, extract gas in the container by vacuum pump out from air extractor duct, reach vacuum partial vacuum state, obviously internal tank gas pressure adds spring pressure less than outside atmospheric pressure, outside atmospheric pressure adds spring pressure and acts on the needle-valve, make needle-valve sealing valve opening tighter, make extraneous air enter container by air extractor duct with by spring application needle-valve osed top valve opening, reach insect protected protection against the tide, mildew-resistant, anti-oxidation effect, guaranteed the quality of stores or medicine, prolonged never degenerating.When gaseous tension in the container during greater than outside atmospheric pressure, then gas is outwards exitted by check valve in the container, when gaseous tension equals outside atmospheric pressure in container, needle-valve seals valve opening again by the pressure of spring, make container be in sealing state again, example: when making pickles, after proper temperature soaked certain hour, fermentation produced gas to the interior vegetables of container through pickled vegetable brine, and container internal pressure is greater than outside atmospheric pressure, gas passes through valve opening, the jack-up needle-valve makes deflection of spring, releases gas through valve pocket by the air extractor duct on the valve gap, internal tank gas pressure is reduced to when equaling outside atmospheric pressure, by the reduction of spring shape, pressure transmission needle-valve seals valve opening again in valve pocket, make seal of vessel, thereby extraneous gas can't enter in the container.Reached isolated external container air admission, the purpose that internal gas still can release, the quality flavor of assurance pickles, hygienic standard, not putrid and deteriorated, easy and simple to handle.

Certainly, the positioning form that is connected between shell of tank and container cover and check valve and the valve body can be any connection positioning form except that being threaded, as segmentation thread forms or bayonet socket form.

The check valve spool can be the spool of any form except that needle-valve also, as ball valve core.
