And the cylinder lower that has an air suctiton inlet 51 that covers cylinder 50 in the bottom of said cylinder 50 hides under 80 the situation, and when opening the lid 10 of container, the air suctiton inlet 51 of cylinder 50 can be to outer exposed, so attractive in appearance in appearance.Also have, in container body 3, be equipped with under the situation of Powdered content, can prevent that powder is prone to sucked by air suctiton inlet 51, valve 90 and sleeve component 70 misoperations are minimized.
Opposite with content shown in Fig. 5 and Fig. 6 a, Fig. 6 b, in order to make piston 30 up-and-down movement successfully, forming vertical engagement groove on the piston 30 or under the outstanding situation that forms binding end portion on the piston guide device 40, also can obtain same effect.
In addition, the valve of installing at the valve groove of said piston 30 32 90, though its material limit especially,, with respect to by forming, can successfully move with better elasticity, so recommended use with said sleeve component 70 identical materials.Said valve 90 forms umbrella continuously by the inclination joint face 90c between the 90b of conical inclination portion, support 90a, the said conical inclination 90b of portion and the support 90a; Wherein, support 90a has hollow bulb 90d and is inserted into (with reference to the enlarged drawing of Fig. 2) in the said valve groove 32 in the downside central interior.
The angle [alpha] that forms between the said support 90a of said valve 90 and the inclination joint face 90c preferably is located at 100 degree to the scope of 130 degree.When said angle [alpha] is spent less than 100, be difficult to seal effectively exhausr port 31, when spending, be sandwiched in the time of maybe exhaust taking place in the exhausr port 31 greater than 130, when air-breathing, be difficult to the phenomenon that comes off.
And the container that the present invention relates to can append around the air suctiton inlet 51 of cylinder 50 as required with vacuum pump 5 filter (not shown) is set, and stops up valve 90 and said raised member 60 so that prevent seed or small Powdered foreign matter.Said filter is attached directly to air suctiton inlet 51 lower ends of said cylinder 50 removably through sticky material commonly used, perhaps adheres to be built in the state that cylinder lower hides in 80.
In addition, shown in Fig. 6 a, Fig. 6 b, owing to be built on the piston guide device 40 in the cylinder 50; From the pair of vertical engagement groove 46a that is provided with in its outside cylindrical portion, the lower end of 46b; Be formed with a pair of horizontal integration groove 47a, 47b along peripheral part at a side direction respectively, so, container body 3 is become when preserving behind the vacuum state; The piston 30 of decline is rotated with respect to piston guide device 40; At this moment, the protruding 39a of a pair of combination, the 39b that on piston 30, forms combines slip with it, thereby piston 30 is in the lock state and keeps sealable locking-in state.
If constituent components as shown in Figure 4 is installed on the lid 10 after assembling each other, the vacuum vessel that the present invention relates to that is made up of above structure forms structure as shown in Figure 2 with vacuum pump 5, and is applicable to container body 3.
To preserve be placed in the container body 3 with food after, cover the lid that vacuum pump 5 is installed 10 as shown in Figure 2, and push the piston 30 of vacuum pump 5 with hand from top, as shown in Figure 3 at this moment, piston 30 is compressing spring 19 and is descending.
At this moment; Along with the decline of piston 30, piston 30 is inner pressurized, and; Be installed in and shrink with sleeve components 70 around the integrally formed raised member 60 of cylinder 50 and be close to around the raised member 60; And this pressure makes the valve 90 in the exhausr port 31 that is located at piston 30 rise a little from exhausr port 31, thereby through exhausr port 31 air in the piston 30 is discharged to the outside by force.At this moment, the 90b of conical inclination portion of said valve 90 is because of the flexible leakage air easily of its peripheral part.
Subsequently; Remove the pressure of pushing piston 30, piston 30 rises owing to the elastic restoring force of spring 19 as illustrated in fig. 2 automatically, at this moment; Rising along with piston 30; Make piston 30 inner spaces become big, thereby in piston 30 inner moments generation negative pressure, said valve 90 sealably cut off the exhausr port 31 of piston 30 fully.Under this state; If piston 30 rises again; Then piston 30 inside form bigger negative pressure state; This negative pressure makes the sleeve component 70 around the raised member 60 be installed in cylinder 50 expand, thus via the air suctiton inlet 51 of cylinder 50 with shown in hollow bulb and the air that sucks in the container bodies 3 through a plurality of openings 61 that are located at the side of raised member 60.The air that is inhaled into flow into piston 30 inside via the hollow bulb of raised member 60 and a plurality of openings 61 that form through its side.
Like this, through pushing piston 30 or removing pressing force, piston 30 is risen and decline.So, after carrying out repeatedly container body 3 in-to-in air are drawn into piston 30 inside, again with it to the action that discharge the outside, make the inside of container body 3 become vacuum state.
That is, to outside air-out by force, make it become low-pressure state, play the effect that food that its inside holds keeps original state for more time, can further prolong the pot-life of food from container body 3 inside.
In addition; The inside of container body 3 is formed after the vacuum state, under the state of piston 30 that descends to greatest extent, if be incorporated into cylinder 50 on the pair of vertical engagement groove 46a, the protruding 39a of a pair of combination, the 39b of piston 30 that 46b combines of piston guide device 40; Along with a pair of horizontal integration groove 47a, the 47b of piston guide device 40 moves; Then form lock-out state, piston 30 becomes the rising holddown, thereby keeps sealable locking-in state.
Afterwards, take out when the food of container body 3 inner preservation certain hours, the vacuum release (relief) valve door 7 of operating common structure allows air to flow into the inside of container body 3, removes vacuum state with this, thereby can easily separate lids 10 from container body 3.
Like this, repeatedly carry out the last lower pumping action of piston 30 repeatedly, discharge by force to the outside after the air in the container body 3 is sucked fully, thereby keep container body 3 in-to-in vacuum states, can food stay-in-grade state be preserved down for a long time.
The vacuum vessel that the present invention relates to can be preserved food such as fruit, aquatic products with long under the original state with vacuum pump freshly.When store to preserve seed etc. little, particularly during pulverous material, also can not shorten because of the rotten and pot-life that misoperation causes, can be used in effectively in the airtight container of preserving food etc.
