Abstract
The utility model discloses a vacuum fresh-keeping box. The vacuum fresh-keeping box comprises a box body, wherein a box cover capable of being combined with the box body in a sealing mode is arranged on the box body, a concave groove is arranged in the upper surface of the box cover, a through hole penetrating through the box cover is arranged at the bottom of the concave groove, a sealing pad playing a role as a one-way valve is arranged on the through hole, an annular boss fixedly arranged at the bottom of the concave groove is arranged at the outer side of the through hole, the annular boss is in threaded connection with a locking cover capable of compressing the sealing pad, the locking cover is screwed up to firmly compress the sealing pad on the through hole, so that when people or other objects touch the sealing pad by mistake, a seam is not generated between the sealing pad and the through hole, external air is prevented from entering the fresh-keeping box, and therefore the fresh-keeping effect of the vacuum fresh-keeping box is guaranteed.
Description
Technical field
The utility model relates to a kind of vacuum crisper for food fresh-keeping.
Background technology
In daily life, no matter go out to carry food or family's store food, reach fresh-keeping purpose in order not make food spoilage, people utilize the vacuum principle to invent vacuum crisper.
present vacuum crisper on the market is generally to be provided with through hole on lid, be provided with the packing seal of check valve effect on through hole, vacuum crisper is by the Bas Discharged it is inner in the through hole of extra air extractor and reach vacuum state, then prevents that by packing seal extraneous air from entering into the inside of vacuum crisper, in the time will opening vacuum crisper, only need to touch the dynamic seal pad with have gentle hands, produce the gap between packing seal and through hole, outside air enters in vacuum crisper, thereby make the inside and outside air pressure of vacuum crisper equate, people just can open vacuum crisper easily, this vacuum crisper is simple in structure, use very convenient, after but above-mentioned vacuum crisper reaches vacuum state, people are in the process of Mobile vacuum crisper, people's hand or other objects easily touch packing seal, between packing seal and through hole, the gap will appear at once, outside air will enter into vacuum crisper inside, thereby make vacuum crisper lose fresh-keeping effect.
The utility model content
In order to address the above problem, it is a kind of simple in structure that the purpose of this utility model is to provide, and can prevent that again encountering packing seal because of people or object false touch makes it lose the vacuum crisper of fresh-keeping effect.
The utility model for the technical scheme that solves its technical matters and adopt is:
a kind of vacuum crisper, comprise box body, be provided with the lid that to be combined with its sealing on box body, the upper surface of lid is provided with groove, the bottom of groove is provided with a through hole that penetrates lid, be provided with the packing seal of check valve effect on through hole, the arranged outside of described through hole has the annular boss that is fixedly mounted on bottom portion of groove, be threaded on described annular boss can the press seal pad tightening cover, be pressed on securely packing seal on through hole by tightening above-mentioned tightening cover, when making people or other object false touches encounter packing seal, can not produce the gap between packing seal and through hole, prevent that outside air from entering in vacuum crisper, thereby guaranteed the fresh-keeping effect of vacuum crisper.
As improvement of the technical scheme, the upper surface of described tightening cover is provided with two and the protrusion on same rectilinear direction, and above-mentioned protrusion can be convenient for people to tighten or unclamp tightening cover to the locking of packing seal.
As further improvement in the technical proposal, the calibration loop that the arranged outside of described annular boss has the inside grooves of being fixedly mounted on and is used for showing date, being provided with on described calibration loop can be along the mobile slide block in its surface, on date when above-mentioned calibration loop and slide block can allow people be used for noting down vacuum crisper to vacuumize, be convenient for people to calculate that in vacuum crisper, article have carried out the number of days of vacuum freshness retaining.
Further, place, the neighboring of described lid is provided with the fastener that is connected for box body, and above-mentioned fastener can make cannot not be tightly connected looseningly between lid and box body.
Further again, the quantity of described fastener is four, and the quantity of above-mentioned fastener is set to four, can make between lid and box body be tightly connected more firm.
The beneficial effects of the utility model are: because the utility model can be with the tightening cover of its locking by being provided with at the packing seal place, after vacuum crisper exhausts vacuum, by tightening tightening cover, packing seal is compressed securely, when packing seal is encountered in people or object false touch, can not produce the gap between packing seal and through hole, prevent that effectively outside air from entering in vacuum crisper, thereby guaranteed the fresh-keeping effect of vacuum crisper; In addition, also be provided with on lid be used to the calibration loop that shows date and slide block, on the date when being used in conjunction with to show that vacuum crisper vacuumizes by slide block and calibration loop, be convenient for people to calculate the interior article of vacuum crisper and carried out fresh-keeping number of days.
