Description

A kind of vacuum fresh-retaining container

Technical field

The utility model relates to a kind of vacuum fresh-retaining container, especially portable vacuum fresh-retaining container.

Background technique

Antistaling container is that the daily daily necessity of one kind gathers around Packed inside for storing various food or drug Cavity can effectively completely cut off dust or the bacterium of external container air, but still have the air of Gai Heqian, food in cavity Or drug still contacts with air and causes to aoxidize, and substantially reduces the time limit of food；Therefore occurs a kind of band in the prior art There is the vacuum fresh-retaining container of Vacuuming structure, to ensure the vacuum state in cavity, the vacuum structure of setting is complicated, and part is numerous It is more, it is not convenient to use；And container inevitably loosens gas leakage due to shaking the valve body for making to maintain vacuum in movement or transportational process, It is unreliable to cause to seal, and is not able to maintain good vacuum state in cavity.

Summary of the invention

For overcome the deficiencies in the prior art, it is simple and can ensure that the vacuum of vacuum is protected to provide a kind of structure for the utility model Fresh container.

The technical scheme adopted by the utility model to solve the technical problem is as follows:

A kind of vacuum fresh-retaining container, including container cavity and chamber lid, the chamber lid is equipped with vacuum orifice, described to vacuumize Mouth is closed by flip sealing cover；Vacuum orifice is built-in with aspirating hole and covers the silica gel check valve of aspirating hole, and the check valve includes The penetration portions of lower part and the seal face on top, the aspirating hole bottom is equipped with the mounting hole for penetration portions insertion, described Surrounding's ring of mounting hole is furnished with the venthole being connected to cavity inner cavity, and the seal face fitting covers the institute at the top of aspirating hole It states flip inner surface and is additionally provided with pressing ring and seal face is pressed at the top of aspirating hole.

The check valve is the closed hollow funnel type structure in bottom.

The funnel type inclined-plane of the check valve is equipped with pillar.

The penetration portions bottom of the check valve is equipped with barb.

Ring wall is convexly equipped at the top of the aspirating hole.

The venthole is arranged in aspirating hole side wall.

Gasket is equipped between the vacuum orifice inner wall and the aspirating hole.

The chamber lid is equipped with recess, and the flip and vacuum orifice are located in recess.

The beneficial effects of the utility model are: check valve is realized unidirectionally by the cooperation of the mounting hole of its penetration portions and aspirating hole The installation of valve, and sealed and cover by the seal face of check valve at the top of aspirating hole, when vacuumizing, air-flow is entered by venthole In aspirating hole, and the sealing sealed end for opening check valve is pumped, and is vacuumized and is finished, and seal face is tight under negative-pressure sucking effect It is tightly fitted at aspirating hole, prevents air-flow from blowing back into cavity；At this point, cover flip, by the pressing ring of flip by seal face side Edge compresses, and guarantees that container check valve in the case where movement or vibration will not loosen, it is ensured that the vacuum sealing state in container Securely and reliably, food is made to keep fresh；Above structure is simple, simple to install, easy to use, can ensure that food can be in for a long time It is fresh-keeping in vacuum space.

Specific embodiment

A kind of vacuum fresh-retaining container embodiment referring to figs. 1 to Fig. 6 is vacuum crisper, including cavity 1 and chamber lid 2, chamber Lid 2 is equipped with vacuum orifice 3, and vacuum orifice 3 is closed by 4 sealing cover of flip；Vacuum orifice 3 is built-in with aspirating hole 31 and covering pumping The silica gel check valve 5 in hole 31, check valve 5 include the penetration portions 51 of lower part and the seal face 52 on top, the bottom of aspirating hole 31 Equipped with the mounting hole 32 for the penetration portions 51 insertion, surrounding's ring of mounting hole 32 is furnished with the venthole being connected to 1 inner cavity of cavity 33, the fitting of seal face 52 covers at 31 top of aspirating hole, and 4 inner surface of flip is additionally provided with pressing ring 41 and is pressed on seal face 52 31 top of aspirating hole.

Referring to Fig. 7, Fig. 8, when being vacuumized using vacuum evacuation device 6 to crisper, flip 4 is opened, vacuum evacuation device 6 It is directed at vacuum orifice 3 to be evacuated, the air in crisper cavity 1 enters in aspirating hole 31 through venthole 33, and opens check valve 5 Seal face 52 be pumped；It vacuumizes and finishes, 1 air pressure inside of cavity is lower than external pressure, and seal face 52 is in suction Under be tightly fitted at aspirating hole 31, prevent air-flow from blowing back into cavity 1.At this point, being closed on vacuum orifice 3 with the lid of flip 4, lift The pressing ring 41 of lid 4 compresses 52 edge of seal face, and guaranteeing container, check valve 5 will not pine in the case where movement or vibration It is dynamic, so that food in crisper is in vacuum sealing state, keeps fresh.

As a preferred embodiment of the present invention, check valve 5 is the hollow funnel type structure of sealed bottom, can make check valve 5 mass become lighter, and seal face 52 becomes thinner, it is easier to be pushed open and sucked by negative pressure of vacuum by air-flow；Seal face 52 It is equipped with pillar 53, user can be started seal face by pillar 53, to carry out pressure release, chamber lid 2 be facilitated to open；It is interspersed The bottom in portion 51 is equipped with barb 54, and check valve 5 is prevented to be extracted when vacuumizing.

Further, ring wall 34 is convexly equipped at the top of aspirating hole 31, ring wall 34 is close in 52 bottom surface of seal face of check valve 5 Top surface is conducive to be better achieved seal face sealing between the two, prevents gas backstreaming；Venthole 33 is arranged in aspirating hole 31 side walls avoid directly being evacuated food and taking up swill particle and enter inconvenient cleaning in aspirating hole.

Preferably, being equipped with gasket 7, the specially inner wall of vacuum orifice 3 between the inner wall and aspirating hole 31 of bleeding point 3 Between ring wall 34, after vacuum evacuation device 6 is directed at vacuum orifice 3, gasket 7 is close at pumping end, keeps vacuum evacuation device 6 real Existing more efficient vacuum detaches.

Chamber lid 2 is equipped with recess 21, and the shape of recess 21 matches with the appearance profile of flip 4, flip 4 and vacuum orifice 3 In recess 21, as 4 Gai Hehou of flip, 4 top surface of flip and 2 flush of chamber lid keep the appearance of container more beautiful.
