ACCESSORIES, CLOSURES, OR FITTINGS THEREFOR; PACKAGING ELEMENTS; PACKAGES ## Abstract A content container includes an outer container having a first accommodation space formed therein; an inner container accommodated in the first accommodation space and having a second accommodation space formed therein; a shoulder part provided at an upper side of the outer container and having a communication space that is vertically penetrated formed therein to allow the inner container to be inserted; and a cover part configured to seal or open the communication space, wherein a base part is formed to protrude along an inner circumference of the shoulder part, a mounting part is formed to protrude along an outer circumference of the inner container, the inner container is accommodated in the first accommodation space of the outer container when the mounting part is mounted on an upper end of the base part, and when the cover part seals the communication space, mounting of the inner container is fixed and the second accommodation space is sealed. ## Claims ### Claim 1 A content container comprising: an outer container having a first accommodation space defined therein; an inner container accommodated within the first accommodation space and having a second accommodation space defined therein; a shoulder part disposed on a first end of the outer container where the first accommodation space is defined, the shoulder part having a communication space that is vertically penetrated defined therein to allow the inner container to be inserted; and a cover part configured to seal or open the communication space, wherein a base part protrudes along an inner circumference of the shoulder part, and a mounting part protrudes along an outer circumference of the inner container, wherein the inner container includes a downwardly curved part extending downward from an outer end portion of the mounting part, wherein the shoulder part includes at least one upwardly curved part extending upward from an inner end portion of the base part, and wherein the at least one upwardly curved part includes a plurality of upwardly curved parts spaced apart along an inner circumference of the base part, and at least one opening defined between the plurality of upwardly curved parts. ### Claim 2 (depends on 1) The content container of claim 1, wherein: an inner support part and an outer support part each protrude from an upper end of the shoulder part; an inner close contact part configured to come into close contact with an outer side of the inner support part and an outer close contact part configured to come into close contact with an inner side of the outer support part are each formed on a lower end of the cover part; and when the cover part moves downward to seal the communication space, the sealing is reinforced as an airtight space formed between the inner close contact part and the outer close contact part is compressed due to downward movement of the inner close contact part and the outer close contact part. ### Claim 3 (depends on 2) The content container of claim 2, wherein: at least one first hooking part is disposed on an outer side of the outer support part of the shoulder part, at least one second hooking part that corresponding to the at least one first hooking part is disposed on an inner side of the cover part; and the cover part seals the shoulder part by a coupling between the at least one first hooking part and the at least one second hooking part. ### Claim 4 (depends on 2) The content container of claim 2, wherein the shoulder part further comprises an outer edge part coupled to the outer container; an inner edge part provided at an inner side of the outer edge part and from which the base part extends inward; and a connecting part configured to connect the outer edge part and the inner edge part and have the inner support part and the outer support part formed on an upper end. ### Claim 5 (depends on 1) The content container of claim 1, wherein at least one pressing part configured to, when the cover part seals the communication space, press an upper end of the mounting part downward to fix and seal the inner container protrudes from a lower end of the cover part. ### Claim 6 (depends on 1) The content container of claim 1, wherein when the inner container is mounted on the shoulder part, an inner surface of the downwardly curved part is supported by an outer surface of the at least one upwardly curved part. ### Claim 7 (depends on 6) The content container of claim 6, wherein, when a sealed state of the second accommodation space is released and contents accommodated in the second accommodation space leak, the contents are introduced into the first accommodation space through the at least one opening, and leakage of the contents to an outside is prevented. ### Claim 8 (depends on 6) The content container of claim 6, wherein, when the mounting part is mounted on the base part, air in the first accommodation space is discharged to an outside through the at least one opening, and an increase in an internal pressure of the first accommodation space is addressed. ### Claim 9 (depends on 1) The content container of claim 1, wherein the inner container is accommodated in the first accommodation space of the outer container when the mounting part is mounted on an upper end of the base part, and when the cover part seals the communication space, mounting of the inner container is fixed and the second accommodation space is sealed.
