The food containers that the utility model relates to vacuum seal 100 is, covering lid after being accommodated in food cooked in the container makes internal tank keep the food containers vacuum seal of vacuum state, as shown in Figure 2, the sealing member that the utility model relates to forms ring-type, in order to be combined on the lid outer peripheral face that joins with container.

The structure of the sealing member 100 that further observation the utility model relates to, then as shown in Figure 3, on the end face of sealing member 100, extend downwards and form lid and be close to portion 102 by the medial end of annular body 101, described lid is close to portion 102 and is extended to the main body outside and form compressing piece 103.

And described main body 101 outboard end are extended upward and are formed container and be close to portion 105, the end that described container is close to portion 105 side-prominent extensions and form bayonet socket 107 in the main body 101.

In addition, be formed with outstanding cyclic lug 106 downwards in the main body 101 of described sealing member 100, in the bottom of described main body 101 side with lid is close to the outside of portion 102 and the top of compressing piece 103 is formed with reinforcing chip 104.

As shown in Figure 3 and Figure 4, described reinforcing chip 104 is formed on the sealing member 100 with radial.

Shown in Fig. 5 A, Fig. 5 B, food containers of the present utility model is combined on the outer peripheral face of lid 220 with vacuum seal 100, when the main body upper surface of sealing member 100 and the lid flange 222 of lid 220 join, the lid flange 222 of lid 220 is inserted in the bayonet socket 107 and the groove 108 between the main body 101 of sealing member 100, makes the lid of sealing member 100 be close on the lid shaft wall 223 that portion 102 is close to lid.

As mentioned above, if sealing member 100 is combined on the lid 220, then covers flange 222 and be inserted in the groove 108 that the sealing member 100 at Fig. 3 forms, thereby sealing member 100 firmly is combined on the lid 220.

As mentioned above, cover container 210 with lid 220 after sealing member 100 being combined on the outside face of lid 220, then shown in Fig. 5 A, Fig. 5 B, the compressing piece 103 of sealing member 100 is close to container flange 211, and the lid of sealing member 100 is close to the perpendicular wall 212 of container that container 101 is close to by portion 105.

In addition, when covering container 210 with lid 220, because the weight of lid 220, the outstanding protrusion 106 extruding compressing pieces 103 in main body 101 bottoms of sealing member 100, and between the main body 101 of sealing member 100 and compressing piece 103, keep prescribed distance.

Cover lid 220 after being accommodated in the food of heat of culinary art in the container 210, then along with the cooling of the food in the container 210, the volume of air of container 210 inside is shunk and is formed vacuum state.

Aforesaid if container 210 inside become vacuum state, its negative pressure causes lid 220 to be attracted by powerful, and the sealing member 100 that is incorporated on lid 220 outer peripheral faces firmly is close on the container 210, to keep vacuum state for a long time.

At this moment, by the cyclic lug 106 outstanding in main body 101 bottoms, main body 101 and compressing piece 103 keep prescribed distance, make the compressing piece on the container flange 211 be close to container 210 not exclusively be close on the main body 101 of sealing member 100, so the problem of sealing member 100 distortion can prevent from using for a long time the time.

In addition, be close to the outside of portion 102 and the top of compressing piece 103 in the bottom of described main body 101 side and lid, be formed with reinforcing chip 104.

As shown in Figure 3 and Figure 4, described reinforcing chip 104 is formed on the sealing member 100 with radial, described reinforcing chip 104 functions as follows, when the valve 221 of opening Fig. 5 is removed after the vacuum state of containers 210 inside uncover 220, because the elasticity of reinforcing chip 104 makes sealing member 100 reinstatements, in addition, lid 220 covers under the state of container 210, described reinforcing chip 104 is exerted pressure compressing piece 103 to vessel side, thereby keeps the vacuum state of container 210 inside reliably.
