Abstract
The utility model discloses a vacuum fresh-keeping device for food, which is also suitable for nonfood isolation from air. The vacuum fresh-keeping device for food is composed of a container, pressure pistons, a compressing air-exhausting chamber, etc. The vacuum fresh-keeping device for food is characterized in that the container is provided with a double-ring-shaped sealing opening, one is a sealing ring, the other is a helical ring opening thereof, and a vacuum display, two pressure pistons, an air suction piston, two rubber sealing rings, the compressing air-exhausting chamber, a pressure spring, and a vacuum forming device are arranged. The container is made of transparent glass. The vacuum forming device is molded by plastic injected die. The vacuum fresh-keeping device for food has the advantages of simple structure and low cost, but can play the vacuum fresh-keeping function.
Description
The utility model belongs to vacuum freshness retaining aspect technology.
Tinned food is the vacuum freshness retaining food that the crowd knows, because of its long shelf-life, can keep original local flavor, portable characteristics, and be widely used in the mining area, field work, aviation, navigation and armament.Also be applied to civilian food, it is very high that unique deficiency is to only limit to disposable fresh-keeping and fresh-keeping technology cost, have only professed machine equipment just can finish, mostly the container of fresh-keeping foodstuff packing is to be made or glass bottle adds the sheet tin lid and makes by sheet tin, but promptly lost the vacuum freshness retaining characteristic with after crossing, become waste product and throw away, caused very big waste like this.
Purpose for " energy savings " " easy to use ", I at the deficiency of tinned food and unique design novel evacuated preservation device, it has the vacuum freshness retaining characteristic of tinned food and easy to use, the individual is manual can to finish vacuum freshness retaining technology, can also repeated use, thus the waste of the expensive raw MAT'L and the energy avoided.
The purpose of this utility model is achieved in that
In transparent glass container, put into food or the fresh-keeping non-edible product of other need, covering fresh-keeping cover (vacuum forms the device housing) makes the article in the container isolated with extraneous air, push vacuum with hand then and form the device piston, air sucking-off in the container is drained into the outside, make internal tank form nearly vacuum state, to reach fresh-keeping purpose.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is that vacuum of the present utility model shows the meter front elevation
Fig. 3 is the detailed construction figure of exhaust gas pressure piston of the present utility model
Fig. 4 is a container scheme drawing of the present utility model
Fig. 5 is a container appearances scheme drawing of the present utility model
Among the figure: 1 air-breathing piston 2 springs 3 exhaust pitions 4 vacuum show that counting 5 fresh-keeping covers (vacuum shaper housing), 6 nontoxic rubber sealing ring pads, 7 vacuum shapers presses piston 8 antistaling containers 9 compression exhaust chambeies 10 exhaust pition enlarged diagrams, 11 compression springs, 12 fresh-keeping cover air entries, 13 vacuum demonstration meter probe 14 helixseal collar extensions 15 flat mouthes sealing collar extension.
Among the figure one, the fresh-keeping device of food vacuum is made up of fresh-keeping cover 5 and antistaling container 8, fresh-keeping cover 5 is formed with compression exhaust chamber 9 by the high-temperature resistance plastice injection molding and is connected as one, can stretch up and down in compression exhaust chamber 9, have an air suctiton inlet 12 to communicate with compression exhaust chamber 9 at fresh-keeping cover 5 middle parts, the air in the air suctiton inlet 12 energy sucking-off antistaling containers 8 is equipped with the air-breathing piston 1 of a unidirectional unlatching on air suctiton inlet 12, just open the air when opening in the sucking-off antistaling container 8 when only being negative pressure in compression exhaust chamber 9.Spring 2 is installed on vacuum formation device and pushes between piston 7 and the fresh-keeping cover 5, is equipped with exhaust piston 3 on compression exhaust chamber 9, makes air can not suck outside air from discharge in the compression chamber 9.In fresh-keeping cover 5 and antistaling container 8 sealings place two nontoxic rubber sealing ring pads 6 are arranged, form device in vacuum and push and have a vacuum to show meter 4 on the piston 7, its probe 13 passes compression exhaust chamber 9 fresh-keeping covers 5 to container 8, contacts with air in the container 8.Container 3 is the pyroceram steel, has two sealing collar extensions 14,15, and wherein helixseal collar extension 14 is for to have the collar extension of two-sided screw thread, and is corresponding with the screw thread hitch on the fresh-keeping cover 8.
7 push the piston front elevation for vacuum forms device among the figure two, and 4 show for vacuum and to count the installation site
Figure three is exhaust piston 3 enlarged drawings, 10 exhaust pistons of making for rubber, and the back is tight against pressure spring 11, just opens when the pressure of air in the compression exhaust chamber reaches certain pressure.
Figure four is the side schematic view of antistaling container
Figure five is antistaling container thread seal ring and the outside drawing that seals collar extension, and the thread seal collar extension is in the outer ring, and flat mouthful of sealing collar extension is at inner ring.
The fresh-keeping program of food vacuum is performed such:
1, in container 8, puts into food, cover fresh-keeping cover 5 then, begin to push vacuum formation device and push piston 7, under the effect of manpower, compression exhaust chamber 9 and spring 2 shrinks, and makes original air from exhaust piston 3 discharges in the chamber in, air-breathing this moment piston 1 is closed, and exhaust piston 3 is opened.
2, when hand lifts, the compression chamber exhaust 9 recovery original state of under the application force of spring 2, upspringing, air are negative pressure state in the compression exhaust chamber 9 this moment, and exhaust piston 3 is closed, and air-breathing piston 1 is opened, and enters air in the container to compression chamber 9.
3, compression exhaust chamber 9 is full of and is full behind the air in the container 8 and closes state, and air-breathing piston 1 is closed, and when pushing vacuum once more when forming device and pushing piston 7, what discharge from exhaust piston 3 is air in the container.
4, so push vacuum and form device piston 7, thereby reach the vacuum freshness retaining purpose progressively with the extremely nearly vacuum state of the eliminating of the air in the container 8.
