Abstract:
A sample processing container comprising:a container body having an accommodating part for accommodating a sample therein, a front engagement part arranged at a front of the accommodating part and a rear engagement part arranged at a rear of the accommodating part; and a lid body whereas at least a part thereof is curved, the lid body having a front side and a rear side, the rear side of the lid body being provided with a rear engagement member which is engageable with the rear engagement part of the container body and the front side of the lid body being provided with a rear engagement member which is engageable with the front engagement part of the container body; wherein engagement of the front and rear engagement members of the lid body with the front and rear engagement parts of the container body respectively allows the lid body to be fitted to the container body and causes the lid body to be elastically deformed into either a plane state or a reduced-curved state in which a degree of curvature of the lid body is reduced; and wherein releasing the engagement of the front engagement member of the lid body with the front engagement part of the container body allows the lid body to be restored elastically, so that the front side of the lid body is separated from the container body, wherein: the front engagement part of the container body comprises: a front engagement member which extends in a left-and-right direction of the sample processing container and which is elastically displaceable in a front-and-rear direction of the sample processing container and also engageable with the front engagement member of the lid body; and an immovable member arranged so that a gap is formed between the front engaging member and the immovable member with respect to the front-and-rear direction; when the front engagement member of the lid body is engaged with the front engagement member, the front engagement member is positioned in the gap between the front engagement member and the immovable member of the container body; and upon depressing a predetermined member into the gap between the front engagement member and the immovable member, the front engagement member of the container body is displaced in the front-and-rear direction due to a wedge action of the predetermined member, whereby the engagement of the front engagement member of the lid body with the front engagement member of the container body is released.
