[0029] The fermented food container according to the first embodiment includes a container body 10 having a plurality of locking protrusions 15 provided along a circumferential outer surface of an open top of the container body at predetermined intervals. The fermented food container further includes an inner lid 20 to close the open top of the container body 10, and an outer lid 35 which is coupled to the container body 10 and spaced apart from the inner lid 20 by a predetermined distance. In the present invention, the locking protrusions 15 constituting a locking unit may be provided in various shapes.
[0030] The inner lid 20 has an inner lid plate 21 which forms an upper plate of the inner lid 20, with a sealing channel 25 defined around an edge of the inner lid plate 21. The sealing channel 25 is opened downwards, so that an edge of the open top of the container body 10 is received in the sealing channel 25 of the inner lid plate 21. The inner lid 20 further has a sidewall part ...
Example
[0041] As shown in FIG. 2, in the second embodiment, an inner lid 120 is not separately coupled to a container body 110, but is integrated with an outer lid 135, unlike the first embodiment. The inner lid 120 has an inner lid plate 121 which forms an upper plate of the inner lid 120 to close an open top of the container body 110, and a sidewall part 122 which extends upwards from an edge of the inner lid plate 121. The outer lid 135 has a sealing channel 141 which is provided under a lower surface of the outer lid 135 to receive therein an upper edge of the sidewall part 122 of the inner lid 120. The inner lid 120 is coupled to the lower surface of the outer lid 135, thus defining a gas storage space between the inner and outer lids 120 and 135. An inner valve unit 30 is provided on the inner lid 120 to discharge fermentation gas from the container body 110 into the gas storage space. An outer valve unit 40 is provided on the outer lid 135 to discharge the fermentation gas from the ...
Example
[0042] As shown in FIG. 3, in the third embodiment, a container body 310 includes an extension part 313 which extends outwards from a circumferential outer surface of an open top of the container body 310 and is bent upwards to extend to a predetermined height. A plurality of locking protrusions 315 are provided along a circumferential outer surface of the extension part 313 of the container body 310 at predetermined intervals. A first sealing channel 321 is defined between the extension part 313 and the circumferential outer surface of the open top of the container body 310. An inner lid 320, which is received in the extension part 313, has a rim part which is provided around an edge of a lower surface of the inner lid. Thus, when the inner lid 320 is placed on the open top of the container body 310, the rim part is received in the first sealing channel 321. An outer lid 335 has a second sealing channel 343 which is provided on a lower surface of the outer lid 335 to receive therei...
