The locking blades are integrally formed so as to be pivotable outward along the edge of the lid, and each of the locking blades is provided with a locking protrusion so as to be caught by the locking protrusion. Therefore, when the lid is covered on the upper part of the container body and then the locking blades are downwardly pressed downward, the latching jaw is elastically coupled to the latching projection of the container body, and the lid is securely locked. When the lock wing is lifted upwards, the latching restraint is released and the lid can be opened.

However, when the lid is covered on the upper part of the container body and then the locking wings are downwardly pressed downward, the upper part of the lid is bent upward convexly by the pressing force of the part to be engaged when the latching jaw is elastically coupled to the latching projection of the container body, A gap such as a square corner of the container main body which is not coupled with the tongue-and-hanging jaw is generated, and a complete sealing is not achieved.

In addition, according to the material of the rubber packing used in the conventional hermetically sealed container, the constant pressing force is maintained for a predetermined time or more, and when refrigerated, the rubber packing is cured and the sealing force is reduced, .

In addition, it is difficult to confirm the shelf life of food or the storage time of the food in the container, and the food is not corroded when stored for a long time, and also affects other foods stored in the refrigerator .

In addition, in the conventional sealed container, the packing is inserted into the lid. In addition to the difficulty of removing the packing, the water is not dried properly, and the packing may be fungus or hygienic due to moss. And, it was inconvenient because it was washed for hygiene but it was not easily washed.

A food sealed container according to the present invention includes a container body (10), a lid (20), and a side sealing packing (40).

First, the upper portion of the container body 10 is opened, and a space for storing food is formed. In addition, the container body 10 may be formed in various shapes such as a square shape or a circular shape.

A catching jaw 25 is formed on the outer peripheral surface of the container body 10 so that the latching protrusion 11 formed on the locking blade 24 of the lid 20 can be hooked.

The lid 20 is capable of opening and closing the container body 10, and has a plurality of locking blades 24 formed on the outer periphery thereof. A plurality of latching protrusions 11 are formed to protrude from the latching jaw 25 by rotating the locking blade 24 of the lid 20.

That is, when the lid 20 is positioned at the upper end of the container body 10 and the locking vane 24 is rotated toward the container body 10, the locking protrusion 11 formed on the locking vane 24, And is caught on the lower side of the latching jaw 25. In this way, the lid 20 and the container body 10 are coupled to seal the inside of the container body 10.

Further, the lid 20 is formed with an outer wall 21 projecting downward at its outer peripheral end.

The lid 20 is formed on the inner side of the outer wall 21, that is, on the lower side of the lid 20, with an inner wall 22 protruding downward at a position spaced apart from the outer wall 21 by a predetermined distance. At this time, the inner side wall 22 is protruded longer than the outer side wall 21.

At this time, the lid 20 has the first fixing groove 23 formed between the outer wall 21 and the inner wall 22 while the outer wall 21 and the inner wall 22 are protruded. In the first fixing groove 23, the upper end of the container body 10 is fitted and fitted.

Further, the lid 20 is inserted into the outer side surface of the inner wall 22 to further form the second fixing groove 26. In the second fixing groove 26, a side sealing packing 40 to be described later is fitted and fixed.

The side sealing packing 40 is inserted and fixed in the second fixing groove 26, and a tightening vane 41 protrudes from the outer circumferential surface.

That is, the container body 10 and the lid 20 are sealed to each other by the side sealing packing 40 while being interposed between the inner side surface of the container body 10 and the inner side wall 22 of the lid 20.

Further, the container main body 10 is provided with the fourth fixing groove 13 which is inserted into the third fixing groove 12.

In addition, the side auxiliary packing 50 is formed with a fixing protrusion 52 on the outer circumferential surface thereof, in which the fourth fixing groove 13 is tightly fixed. Accordingly, the side auxiliary packing 50 is stably fixed to the third fixing groove 12 while the fixing protrusion 52 is fitted into the fourth fixing groove 13.

Particularly, the diameter of the fixing protrusion 52 increases as the protrusion is formed. Therefore, when the lid 20 is detached from the container body 10, The side auxiliary packing 50 is prevented from being detached from the container body 10 together with the lid 20 in a state in which the close contact vane 41 and the close contact groove 51 are engaged by the internal pressure of the lid 20.

Also, the plurality of tightening vanes 41 are formed to protrude by being inclined at a certain angle toward the lower side as the protrusions are formed.

The contact grooves 51 are formed by a plurality of openings, and are inclined at an angle toward the lower side as they are inserted and formed.

That is, the tightening vane 41 is inclined at a predetermined angle to protrude and is smoothly inserted into the close contact groove 51. The number of the contact blades 41 and the number of the contact grooves 51 is correspondingly formed, and preferably three contact blades 41 are formed. The sealing force between the inner side wall 22 of the container main body 10 and the outer side surface of the inner side wall 22 of the lid 20 is increased three times by forming three tightly connecting blades 41 and three contact grooves 51. [

Accordingly, the food sealed container according to the present invention is formed as described above, thereby completely sealing the inside of the container body 10, preventing contact with the outside and preventing food spoilage, and even if foods are stored for a long time The odor of the food or the gas generated by the food is not discharged to the outside, thereby keeping the inside of the refrigerator fresh.

The period display section 62 includes a display section 63 on which a day set by the day setting button 66 is displayed and a time display section 64 on which a time set by the time setting button 67 is displayed .

The status display unit 61 displays the food status as the day and time displayed on the time display unit 64 are counted down by the control unit.

In other words, the control unit displays on the time display unit 64 the day and time set when the day of the week is set by the period setting unit 67. Then, the control unit immediately starts to count down the time and date displayed in the time display unit 64, that is, the period. At this time, the control section divides the set period into four stages by dividing setting in advance. If the day and time displayed in the time display unit 64 belong to the period divided by the division setting, the control unit brightens the brightness of the portion of the status display unit 61 corresponding to the belonging step.

Here, the status display section 61 displays four levels of 'fresh', 'normal', 'danger', and 'corruption'. In addition, the division setting is based on the set period of 10, and is defined as 'fresh' from 0 to 3/10, 'normal' from 4/10 to 7/10, 'danger' from 8/10 to 1, Corruption ', but is not limited thereto.

For example, when the user puts the tofu into the container body 10 and closes the container through the lid 20, and sets the remaining shelf life of the tofu 00 hours by using the period setting unit 67, '05: 00' is displayed on the display unit 62 and the period is counted down by the control unit. Here, the controller sets 'fresh', 'normal', 'danger', and 'corruption' through the division setting and brightens the brightness of the 'fresh' portion of the status display unit 61. If the period of five days has elapsed, '00: 00' is displayed in the period display section 62 and brightness is brightly adjusted in the 'corruption' part of the status display section 61.

Accordingly, the user can easily recognize the expiration date, and it is possible not only to reduce the amount of discharged food by treating the food before expiration of the expiration date, but also to prevent ingestion of the food after expiration of the expiration date, .
