Description

Food preserving box

Technical field

The utility model relates to a kind of crisper manufacture technology field, especially refers to the fresh-keeping bright box of a kind of sealing that can bleed.

Background technology

Existing a kind of patent No. is that 03232316.6 Chinese utility model patent that is called " vacuum crisper " has proposed a kind of structure, it is provided with seal ring on the faying face of box body and lid, have through hole on the lid, the top of through hole has been provided with the packing seal of check valve effect, described packing seal is limited in shoulder in the stop lid, in stop lid then snapped onto and renovates with the lid pivotally attached, the middle body that it is characterized in that described packing seal was the thin-wall semi hull shape of epirelief and exposes outside the stop lid; Cover in stop in addition and also be provided with date stamp.Have to be easy to judge whether still be in the vacuum freshness retaining state in the box and understood food preservation advantage how long, and easy and simple to handle, be suitable for the fresh-keeping storage of food.The shortcoming of this crisper is a complex structure, the cost height, and the packing seal of described thin-wall semi hull shape is damaged easily, service life is short, so actual application value is little, so its structure is still waiting to improve.

Summary of the invention

Technical problem to be solved in the utility model is that a kind of simple in structure, use, easy to carry and food preserving box with air extracting seal function are provided at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this food preserving box, include box body and lid, on lid, be provided with through hole, described lid detached type lid places on the box body, and be provided with seal ring between lid and the box body, described lid is for having compressible elastomeric cap, and be provided with the cavity of upward opening on the lid surface, described through hole is positioned on the cavity bottom surface, and in cavity, be provided with and seal device close and the unlatching through hole, it is characterized in that described device comprises a rotatable cover plate that is arranged in the cavity, on the eccentric position of this cover plate, have air extractor vent, in air extractor vent, be provided with the sealing member suitable with through hole.

As improvement, described cavity can be preferably circular-shaped, concave cavity, and described cover plate is by with the suitable round of circular-shaped, concave cavity be positioned at pulling to buckle and forming of round top, described air extractor vent is positioned at that round and pulling is smashed and upper and lower opening and being connected, and described sealing member is up-small and down-bigly to be platform level shape and to be arranged in the air extractor vent.

As further improvement, described lid detached type lid places the structure on the box body to may be selected to be its periphery of described lid to extend downwards and the suitable bulge loop of box body inner chamber, this bulge loop is that the inner chamber that is inserted in box body covers and places on the box body, and described seal ring is to be placed on the periphery of bulge loop; And described seal ring is formed by sealing big protruding circle and sealing little protruding circle, and is fixed on the upper-lower position compartment of terrain on the peripheral groove of bulge loop; The big protruding circle of described sealing and seal little protruding circle and be designed to integral structure; And described through hole is " T " font, and also is provided with the annular arrangement projection that can play better sealing function with easier being close together in sealing member bottom surface on the periphery of its upper end open.

Improve again, it is arranged at the jack that center that structure in the lid cavity may be selected to be cover plate is provided with lower openings rotationally described cover plate, and the center that is positioned at cavity convexes with inserted link, described cover plate is inserted on the inserted link by jack sleeve, and cavity is provided with little protruding button the in the location that can conveniently make cover plate back seal spare seal through hole, and this little protruding button matches spacing with the spacing inner chamber two side of pulling button.

Compared with prior art, device of the present utility model adopts a rotatable cover plate that is arranged in the cavity, has air extractor vent on the eccentric position of this cover plate, is provided with the sealing member suitable with through hole in air extractor vent.This structure is behind the tray cover upper box cover, seal through hole again, push lid with hand, gas in the box body can be discharged, because of sealing member is that flexible material is made, when making the volume-diminished of box body so push lid, the impulse force of gas makes sealing member generation deformation and discharges in the via through holes in the box body, when letting go, extraneous barometric pressure is sealed the sealing member compressing with through hole, thereby lid can be unified with tray cover securely, and does not need other fixed sturcture, be easy to carry, and in the time will opening,, make the box body inner and outer air pressure keep balance as long as open through hole, can like a cork lid be opened, so use very convenient; And the design's crisper is simple in structure, and He Gai and its bulge loop can be made in disposable injection moulding, and be simple in structure, and it is low to make adult; If gas leak phenomenon can reach good sealing effectiveness as long as change seal ring, again so service life is also long; Have, crisper of the present utility model can be made from a variety of materials again, as long as its lid possesses to push with hand elastic deformation can take place.So the utility model is a kind of product of great practical value, is worthy of popularization.
