Heat retaining device

A heat retaining device configured to retain a container containing a sample therein at a predetermined temperature, comprising:

• a heat retaining body having an upper face;
• an opening part in the upper face of the heat retaining body;
• an elastic body embedded in the opening part and having an upper face, the upper face of the elastic body being positioned at the same level as the upper face of the heat retaining body;
• and
• a top plate positioned to cover the upper face of the heat retaining body, wherein the elastic body includes a hole at the upper face thereof, the hole being configured to contain the container therein and having an inner face shaped corresponding to a shape of an outer face of the container,
• wherein
• a pressing force, which is applied to a hermetic-sealing closure to be fitted to the container fitted in the hole of the elastic body, compresses the elastic body to move the container downward, wherein release of the pressing force returns the elastic body to an original state and returns the container to an original position, and wherein
• the downward movement of the container brings the container into contact with the top plate.

A heat retaining device configured to retain a container containing a sample therein at a predetermined temperature, comprising:

• a supporting rod;
• a top plate mounted at an upper end of the supporting rod;
• a bottom plate mounted at a lower end of the supporting rod;
• a heat retaining body disposed between the top plate and the bottom plate, the heat retaining body including a hole shaped corresponding to a shape of an outer face of the container;
• and
• a release mechanism which detaches the container contained in the hole of the heat retaining body from the hole of the heat retaining body.

An analyzer comprising:

• a heat retaining device configured to retain a container containing a sample therein at a predetermined temperature;
• a hermetic-sealing closure fitting device to fit a hermetic-sealing closure to the container;
• and
• a detector to detect a reaction product contained in the container,
• wherein
• the heat retaining device includes a supporting rod, a top plate mounted at an upper end of the supporting rod, a bottom plate mounted at a lower end of the supporting rod, a heat retaining body movable along the supporting rod, and a supporting spring provided between the heat retaining body and the bottom plate,
• the heat retaining body includes a hole at an upper face thereof, the hole being configured to contain the container therein and having an inner face shaped corresponding to a shape of an outer face of the container, and
• when a hermetic-sealing closure is fitted to the container contained in the hole of the heat retaining body by the hermetic-sealing closure fitting device, a pressing force applied from the hermetic-sealing closure fitting device to the hermetic-sealing closure compresses the supporting spring to move the heat retaining body downward along the supporting rod, and release of the pressing force moves the heat retaining body upward by an elastic force of the supporting spring until the heat retaining body comes into contact with the top plate.

A heat retaining device configured to retain a container containing a sample therein at a predetermined temperature, comprising:

• a heat retaining body;
• an elastic body provided at an upper face of the heat retaining body, the elastic body including a hole at an upper face thereof, the hole being configured to contain the container therein and having an inner face shaped corresponding to a shape of an outer face of the container,
• wherein
• a pressing force applied to a hermetic-sealing closure so as to be fitted to the container fitted in the hole of the elastic body compresses the elastic body, and release of the pressing force returns the elastic body to an original state and returns the container to an original position;
• and
• a vibration/impact device configured to apply one of vibration and impact to the container held in the hole of the elastic body.

• a supporting rod;
• a top plate mounted at an upper end of the supporting rod;
• a bottom plate mounted at a lower end of the supporting rod;
• a heat retaining body movable along the supporting rod;
• an elastic body provided at an upper face of the heat retaining body, the elastic body including a hole at an upper face thereof, the hole being configured to contain the container therein and having an inner face shaped corresponding to a shape of an outer face of the container,
• wherein
• a pressing force applied to a hermetic-sealing closure to be fitted to the container fitted in the hole of the elastic body compresses the elastic body, and release of the pressing force returns the elastic body to an original state and returns the container to an original position, wherein
• the bottom plate is provided with a cam protrusion, and the heat retaining body includes an opening at a lower face thereof, the opening being connected to the hole at the upper face of the heat retaining body, and the cam protrusion being disposed in the opening, and
• when the heat retaining body moves downwardly along the supporting rod, the container stored in the hole of the heat retaining body is lifted from the hole of the heat retaining body by a cam function between the cam protrusion and the container.
