Technical field

The utility model relates to a kind of vacuum heat-preserving Food preserving container.

Background technology

At present existing multi-form incubation chamber and vacuum packaging bag, but most incubation chamber all is to adopt thermal insulation material to reduce distributing of heat as box body, not only heat-insulating property is good inadequately, and can not play fresh-keeping effect to the food that is positioned in the box body, its cost of the warm material that will choose is inevitable also high in addition; And present vacuum packaging bag all is to adopt the food with the bag inner packing to vacuumize, make food and the isolated mode of air, reach the purpose of fresh-keeping food, this vacuum packaging bag does not only have function of heat insulation, and basically all can only be when Production and Packaging disposablely vacuumize use, open the function of the vacuum freshness retaining that just is difficult to behind the bag to recur.

The utility model content

The purpose of this utility model is to provide a kind of vacuum heat-preserving Food preserving container, uses this container to place food, can not only play good incubation and thermal insulation function, but also have fresh-keeping function.

Technical solutions of the utility model are to constitute like this, it comprises shell of tank and is located at the interior glove chamber of shell of tank, shell of tank is provided with lid or the door body that is used to open or close the glove chamber and is used to make the glove chamber to form the extraction device of air of vacuum or antivacuum state, described shell of tank and lid or door body are made of double-deck or double-deck above wall body, are provided with vacuum chamber between the adjacent two layers wall body.

Than prior art, the utility model vacuum heat-preserving Food preserving container is owing to can play the dual function that vacuumizes to the glove chamber in shell of tank itself and the housing, therefore have the following advantages: (1) can make be positioned over the indoor food of glove and air isolated fully, thereby avoid food to contact and go bad, play the effect of fresh-keeping food with airborne material; (2) reduce the air dielectric that transmits heat, can play incubation and thermal insulation function preferably; (3) insulation is used during food delivery such as not only applicable fast food restaurant, restaurant, and also applicable to the insulation of family to food, the user can undergo no deterioration food preservation one day, is particularly suitable for the working clan and is with meal to use.

The utility model technique scheme has also been done following improvement:

In order to reach better incubation and thermal insulation function, wall body is provided with insulation material layer around the described glove chamber, by insulation material layer indoor food of glove and glove chamber wall body is all around separated, and can further avoid heat outwards or inwardly to transmit.

In order to make the indoor temperature of glove can further adapt to the needs that food is preserved, also be provided with thermal source or low-temperature receiver supplying layer on the wall body around the described glove chamber, insulation material layer is positioned at the periphery of thermal source or low-temperature receiver supplying layer.Distribute or absorbed heat can make the indoor food of glove maintain in the certain temperature range as far as possible for a long time by thermal source or low-temperature receiver supplying layer.

Make the glove chamber form vacuum or antivacuum state quickly and easily for the ease of the user, described extraction device of air comprises to be located on the shell of tank and to be used to make the turnover gas passage that the glove chamber is communicated with outside air and to be located at check valve on the turnover gas passage respectively, and the check valve on the free air diffuser also is connected with the handle of protruding porthole.After placing food and having closed lid, just can outwards bleed by outlet passageway, the interior check valve of outlet passageway this moment is opened passage under pressure automatically, and the check valve in the free air diffuser is the SELF CL passage under pressure, can make the indoor vacuum state that reaches gradually of glove by bleeding.In the time will opening lid and get food, be pulled outwardly the handle on the free air diffuser check valve, free air diffuser is opened, just can in free air diffuser, inject air, thereby make inner and outer air pressure reach balance, be convenient to the user and open lid.

With the state that is evacuated in the vacuum chamber, described shell of tank and lid or door also are provided with on the body and are used to able to turn on or off bleed-off passage that the vacuum chamber in its wall body is communicated with outside air for the ease of the user.

In order to prevent gas leakage, be provided with sealing arrangement between the joint face of described lid or Men Tiyu shell of tank.

In order to prevent that shell of tank produces distortion when vacuumizing, can be provided with reinforced rib or reinforcing prop between the adjacent wall of formation vacuum chamber.

In order to prevent that the glove chamber produces distortion when vacuumizing, glove is indoor also can be provided with reinforced rib or reinforcing prop.
