The application method and the course of work of the present embodiment are as follows：

As shown in Figure 2,3, fresh-keeping cover is filled on crisper 4, ring packing side 22 can by 4 inner wall of crisper squeeze to Radial compression, while the air inside crisper can be squeezed out to a part, and the inner wall under natural resiliency effect with crisper 4 Realization of combining closely seals.After fresh-keeping cover installs, sealing piston 3 is pressed, makes elastic packing disk 33 and 11 bottom surface of bleeding point Contact.When vacuumizing, the suction nozzle of vacuum machine is made to cover bleeding point, air-flow enters elasticity from the gas passage between locking protrusion 34 Gap between piston boit 32 and stomata 12, and then elastic packing disk 33 is opened, it is extracted out from crisper.Due to family during this Generally little with the power of vacuum machine, under the locking effect of locking protrusion 34, sealing piston is not fallen out.Vacuumize end Afterwards, vacuum switch is closed, removes and vacuumizes host, then elastic packing disk 33 is pressed into flat abutting under atmospheric pressure effect The glossy bottom surface of bleeding point 11 realizes vacuum freshness retaining so that gas be prevented to enter crisper.

As shown in figure 4, when needing to open fresh-keeping cover, pinch piston cap 31 extract sealing piston make elastic packing disk 33 from The bottom surface for opening bleeding point 11 can pressure release.Since the hollow construction of yielding movable stick harness 32 has preferable flexible and extrusion performance, When extracting and install manually, locking protrusion 34 can be pressed against 32 center of yielding movable stick harness by 12 inner wall of stomata and gather, to pass through Stomata 12 is not easy to be damaged, and can be repeatedly used for a long.If not engaging protrusion 34, only retention bead 35, although not having to frequency Numerous dismounting sealing piston, still, if hand leaves sealing piston, sealing piston can decline naturally under the effect of gravity, so that bullet Property seal disc 33 contacted again with the bottom surface of bleeding point 11, formed sealing state.In this case, although pressure release early period So that crisper inside and outside air pressure balance, still, since the junction of fresh-keeping cover and crisper has certain elasticity, guarantor when uncapping The inner space of fresh box can be stretched increase, be lower than external pressure again so as to cause crisper air pressure inside, difficulty of uncapping.If One hand pinches sealing piston, if another hand one hand is uncapped, for somewhat larger crisper, and will lead to operation not Just.

Therefore, the present embodiment setting locking protrusion 34, when locking protrusion 34 is located above the bottom surface of bleeding point 11, user Hand can leave sealing piston, locking protrusion 34 prevents sealing piston from falling, and keeps being in communication with the outside inside crisper, balance Inner and outer air pressure, so as to use both hands smoothly to uncap.Meanwhile locking protrusion 34 has apparent Caton when extraction from stomata 12 Sense, and since the diameter of retention bead 35 is greater than the diameter of locking protrusion 34, after locking protrusion 34 is extracted from stomata 12, When retention bead 35 and 12 lower edge of stomata contact, user can experience pull-out resistance and increase suddenly, Caton sense and extraction resistance The feel that power increases suddenly may help to the position of user's visual perception sealing piston, realize " blind operation ".Also, bleeding point 11 bottom surface is stuck between locking protrusion 34 and retention bead 35, and sealing piston is not easily to fall off, avoids frequently dismounting or losing, Prolong the service life.User does not need hand steered sealing piston, therefore can normally be uncapped with both hands.

Since ring packing side 22 is set in circular body portion 21, ring packing side 22 is the horn-like structure of opening upwards It makes, there is elasticity, and diameter under natural conditions is greater than the diameter in crisper matching face, under lid when fresh-keeping cover, ring packing The radial contraction under the extruding of crisper inner wall of side 22, while the air inside crisper is squeezed out into crisper a part, until Crisper inside and outside air pressure balance；Be not switched on sealing piston, i.e., when opening fresh-keeping cover under holding air-tight state, ring packing side 22 Since natural resiliency is still tightly attached to crisper inner wall, leading to fresh-keeping cover is only to rise a distance, crisper during this Inner space is in the state that is stretched, and atmospheric density reduces, and inner and outer air pressure becomes air pressure inside less than external gas from equilibrium state Pressure prevents fresh-keeping cover from opening, to increase difficulty of uncapping, can prevent from opening by mistake lid.If needs are uncapped really, then opens sealing and live Plug makes the inside and outside connection of crisper, and air pressure is always consistent, can smoothly uncap.

In certain occasions, such as user's band after vacuum sealing food of being in is gone out as box lunch, but outside and be not eager or Inconvenience eats up food at once, and at this time due at one's side without vacuum machine, but it is inconvenient vacuumize again, fresh-keeping cover is non-at this time Self-sealing performance and avoiding improper opening under vacuum state anti-spill performance and are particularly important.

Fig. 7~10 are please referred to, is the 3rd embodiment of the utility model, is with the main distinction of the first two embodiment The up and down motion of sealing piston 3 is realized by rotation.Specifically, bleeding point 11 is radially inside set there are two about axis The guide post 114 that line symmetrically and to axis direction protrusion is arranged；It is set on piston cap 31 there are two guide groove symmetric about the axis, Each guide groove includes vertical slot 313 and lateral skewed slot 314, and 313 lower ending opening of vertical slot is for the insertion of guide post 114, laterally tiltedly 314 head end of slot is connected to 313 top of vertical slot, and the tail end height of lateral skewed slot 314 is lower than head end, is tilted between head end and tail end It crosses, the depth displacement of head end and tail end is at a distance from sealing piston moves up and down when rotating.In the present embodiment, lateral 314 tail of skewed slot End is mainly used for resting on the stabilization of guide post 314 at this, external environment vibration or improper stress is avoided to miss there are also a flat segments Revolve piston cap 31.

3 installation process of sealing piston and motion principle of the present embodiment are as follows：313 alignment guide column 114 of vertical slot is packed into Bleeding point 11, when guide post 114 is located at the interconnecting piece of vertical slot 313 and lateral skewed slot 314, locking protrusion 34 passes through stomata 12, 12 lower section of stomata is reached, and elastic packing disk 33 is then contacted with 11 bottom surface of bleeding point, and stomata 12 is covered.When rotating clockwise work When cock cap 31, transversely skewed slot 314 moves guide post 114, actual since guide post 114 is fixed in bleeding point 11 The result is that piston cap 31 moves upwards, so that yielding movable stick harness 32 be pulled up, locking protrusion 34 is pulled out into 12 top of stomata.It is complete It when full opening, will be connected to inside and outside crisper 4 by air slot 36, carry out pressure release.When due to fully opening, guide post 114 is located at The flat part of lateral 314 tail end of skewed slot, can not only prevent sealing piston from falling naturally, but also can be to avoid sealing piston from lid 1 On fall off.Reversely rotating piston cap 31 again returns to guide post 114 at vertical slot 313, then yielding movable stick harness 32 is driven to transport downwards It is dynamic, so that locking protrusion 34 is passed through stomata 12, reaches 12 lower section of stomata, and elastic packing disk 33 is then contacted with 11 bottom surface of bleeding point, Again stomata 12 is covered.

As it will be easily appreciated by one skilled in the art that the above is only the preferred embodiment of the utility model only, not To limit the utility model, any modification made within the spirit and principle of the present invention, equivalent replacement and change Into etc., it should be included within the scope of protection of this utility model.
