Abstract

The utility model relates to a decompression container. A cover body composed of a base, a pressing casing, a spring, a unidirectional opening air gate and an oil seal is directly buckled on a tank body. An air chamber composed of a base, an upright wall and a pressing casing is arranged in a container. Air in the tank body is compelled to be exhausted by the air gate through the force application of the pressing casing and the press of the pressing casing, and the pressing casing is pushed to rise by the spring to make the air chamber expanded after external force is eliminated. The air in the container can be extracted via the operation for a plurality of times, which is favorable to the preservation of foods and articles. The utility model which has a simple structure is suitable for being used for a family.

Description

Decompression container

The utility model relates to a kind of pressure reduction vessel of preserving food, article use, and especially a kind of container itself has the container of the pressure reduction structure that extracts some air.

It is a kind of better method of preserving food, article that food, implements are completely cut off with air as far as possible, yet general family is difficult in and realizes above-mentioned hope under the simple condition owing to lack this equipment.

There are following three kinds of modes can make food or article and air isolated at present, the vacuum packaging that the first is carried out with mass production method in factory; It two is to establish a valve on container, and the equipment that is equipped with in addition by dust collecting fan etc. comes extracting air; The 3rd installs air extractor as US Patent us4911314 on bottle.

Above-mentioned first kind of mode can't be implemented in general family easily; The second way needs to prepare in addition suction device, uses inconvenience; The third mode is because of using on bottle, its fixed form, and pressure regulating equipment all has limitation.

The purpose of this utility model proposes a kind of can the use in average family, simple in structure, effect of easing stress is good, and container can store the pressure reduction vessel of respective volume article, and does not need other attendant equipment.

The utility model is achieved in that it comprises tank body 1, lid 2, is characterized in that: by pedestal 3, form lid 2 by pressure shell 4, spring 5, valve 6, oil sealing 7, pedestal 3 be installed in the lid bottom and with tank body 1 snapping; Central authorities at pedestal 3 are provided with unidirectional unlatching valve 6, and upstanding wall 3b is set around the outer shroud of valve 6, encircle 3c establishing above the upstanding wall 3b, establish flange and spring 5 build-ins around valve 6 by the inwall middle part of pressure shell 4; Between by the flange 4b of pressure shell 4 and steady ring 4c, oil sealing 7 is set, described outer rim 4a and the last ring 3c bearing fit of pressing pressure shell, presses pressure shell flange 4b and upstanding wall 3b bearing fit; Described pedestal 3, upstanding wall 3b, by forming air chamber between the pressure shell 4.Tank body 1 upper limb and pedestal 3 are with oil sealing 3a driving fit.Press the diameter of the gap of the steady ring 4c of pressure shell 4 and flange 4b greater than oil sealing 7.Press pressure shell flange 4b groove with holes, steady ring 4c is provided with breather hole.

The utlity model has simple in structurely, the characteristics of method of operation can reduce the air of internal tank easily, preserve food, article effectively.

Fig. 1 is for the utility model generalized section--spring is in open configuration.

Fig. 2 is for the utility model generalized section--spring is confined state.

Now further narrate structure of the present utility model in conjunction with the accompanying drawings:

Referring to Fig. 1-2: the utility model comprise comprise pedestal 3 in tank body 1, lid 2, the lid, by pressure shell 4, spring 5, valve 6 and oil sealing 7.Food or article are positioned in the tank body 1.Tank body 1 can manufacture various height as required, so that place the article of different volumes, shown in tank body 1.

Lid 2 refers to the integral body of tank body more than 1.Lid 2 is with after tank body 1 combines, and can extract air in the tank body 1 to preserve food or article.

Pedestal 3 is the fixed position of lid 2 belows, be closed state by oil sealing 3a and tank body 1, central part at pedestal 3 is provided with valve 6, the upstanding wall 3b of one annular arrangement is set on around the outer shroud of valve 6, above upstanding wall 3b, establish and encircle 3c on one, form a stable upstanding wall 3b body, so that cooperate with oil sealing 7 by pressure shell 4.

At above-mentioned pedestal 3, upstanding wall 3b, press between the pressure shell 4 and to form an air chamber.On circular outer rim 4a, oil sealing 7 is set by pressure shell 4, flange 4b is established in the below of this outer rim 4a, above oil sealing 7, establish steady ring 4c, gap between steady ring 4c and flange 4b is greater than the diameter of oil sealing 7, that is to say, oil sealing 7 can rely on the flange 4b, and is one at interval with steady ring 4c, or oil sealing 7 is against steady ring 4c and makes and form the gap between oil sealing 7 and flange 4b; Spring 5 is arranged at the bosom by pressure shell 4, and the central space of this spring 5 just can ccontaining valve 6, spring 5 can not be hindered and the function of valve 6 when the action of stretching, pressing; Valve 6 is a check valve, it is not when pressing by pressure shell 4, be the state of closing, when pressing by pressure shell 4, air in the air chamber can't follow this valve 6 and enter in the container, only when being subjected to spring 5 to make progress jack-up by pressure shell 4,, just making the interior appearance gas of container follow this valve 6 and enter in the air chamber because of the rarefaction of air in the air ratio container in the air chamber.The matching relationship of above-mentioned oil sealing 7, upstanding wall 3b and outer rim 4a is: when pressing down by pressure shell 4, oil sealing 7 is against steady ring 4c place, and the gas in the air chamber follows flange 4a, oil sealing 7 and by discharging at steady ring 4c place; And when making progress by pressure shell, steady ring 4c is against ring 3c below, and oil sealing 7, upstanding wall 3b and flange 4b form a closed state, the interior infrabar of air chamber this moment, and rarefaction of air, the air in the tank body 1 is entered in the air chamber by valve 6 automatically; So repeatedly, through after the compression of several times, the gas in the tank body 1 is extracted major part.Said flange 4b has hole slot, if the time be closed by oil sealing 3a compressing; Whether steady ring 4c has breather hole, no matter oppressed by oil sealing 3a, can both breathe freely.

When pushing downwards by pressure shell 4, spring 5 is compressed, when pushing the external force disappearance, because the screen resilience of spring 5, automatically make by pressure shell 4 and rise, therefore, in needs extract jar during air, only need the application of force downwards by giving as security by pressure shell 4, after discharging some air, press pressure shell and can recover automatically to rise, once more by signature, just can begin second and take turns extracting air, so by giving as security repeatedly, outside the air exhaustion jar that can extract right quantity.

In order to strengthen inspiratory effects, in by pressure shell 4, spring 5 foreign sides are provided with a fixed block 8, when making by the air of pressure shell 4 in discharging air chamber, also corresponding the reducing in space in the air chamber.

Connect pedestal 3 and last ring 3c with tightening screw 9.
