Container cap for storing specimen

A container cover for specimen storage, the container cover comprising:

• a cover body comprising a tubular side portion and a bottom portion coupled to one end of the tubular side portion, the cover body being detachably screwed to open one side of a specimen preservation container in which one or more specimen collection swabs are provided by insertion, each of the one or more specimen collection swabs including a stick portion;
• an insertion coupling portion formed so as to protrude from the bottom portion toward the specimen preservation container, the insertion coupling portion having an inner space defined therein such that the stick portion can be inserted and fitted into and coupled to the inner space;
• and
• a protruding fitting portion located in the inner space, the protruding fitting portion being formed so as to protrude from the bottom portion, the protruding fitting portion being configured such that the stick portion is fitted and coupled between an outer surface of the protruding fitting portion and an inner surface of the insertion coupling portion, wherein
• when the specimen preservation container is coupled to the container cover, the stick portion is fitted into and coupled to a position in the inner space,
• the container cover further comprising a separation prevention portion provided at the insertion coupling portion, the separation prevention portion being caught by the stick portion in a contact state when the cover body is coupled to the specimen preservation container to prevent the stick portion from being separated from the insertion coupling portion, wherein
• the separation prevention portion comprises a catching portion formed at the inner surface of the insertion coupling portion so as to protrude therefrom and formed along the inner surface,
• when the cover body is screwed to the specimen preservation container, the stick portion is guided toward a lower surface of the cover body along the catching portion so as to be fitted into and coupled to the insertion coupling portion,
• the catching portion is formed so as to be spirally wound a plurality of times around the inner surface of the insertion coupling portion in response to rotation of the container cover by screw coupling, and
• when the cover body is screwed to the specimen preservation container, the stick portion is guided toward the lower surface of the cover body along the spiral catching portion so as to be fitted into and coupled to the insertion coupling portion.
