Abstract

A test reagent container includes: a bottom part; a peripheral wall part on the periphery of the bottom part; a storage part which opens upward and with an internal diameter of an inner peripheral wall decreased with depth; a film which seals the opening of the storage part; a discharge channel which penetratingly passes from an inner bottom surface of the storage part to the bottom part of the container body; a projecting part formed downwardly projecting from the bottom part to seal an outlet of the discharge channel; a breakable part including a thick-walled part and a thin-walled part thinner than the thick-walled part formed on the periphery of the projecting part. The breakable part is broken when the projecting part is depressed from outside of the container, the projecting part is inserted into the inside of the discharge channel, and the sealed state of the outlet is released.

First claim

The invention claimed is:

1. A test reagent container comprising:
a bottom part;
a peripheral wall part which is erected on a periphery of the bottom part;
a storage part which opens upward and is formed such that an internal diameter of an inner peripheral wall is continuously decreased with depth from an upper portion to a lower portion of the inner peripheral wall;
a stretchable film which seals an opening of the storage part and is pressurizable from an outside of the container;
a discharge channel which passes from an inner bottom surface of the storage part to the bottom part of the container in a penetrating manner; and
a projecting part which is formed in a downwardly projecting manner from the bottom part so as to seal an outlet of the discharge channel, wherein
a breakable part composed of a thick-walled part and a thin-walled part thinner than the thick-walled part is formed on a periphery of the projecting part, the breakable part is broken when the projecting part is depressed from the outside of the container, the projecting part is inserted into an inside of the discharge channel without reaching the storage part, a sealed state of the outlet is released, and
wherein the film is inflatable into the storage part thereby discharging a content of the container and extendable to the inner bottom surface of the storage part without reaching the discharge channel.

2. The test reagent container according to claim 1 , wherein the thin-walled part is continuously formed so as to extend over ¼ or more of a length of the whole periphery of the projecting part.

3. The test reagent container according to claim 1 , wherein the thin-walled part is formed on the periphery of the projecting part at a plurality of positions, and at least one of the thin-walled part is continuously formed so as to extend over ¼ or more of length of the whole periphery of the projecting part.

4. The test reagent container according to claim 1 , wherein an internal diameter decreasing rate is greater in the lower portion than in the upper portion of the inner peripheral wall of the storage part.

5. The test reagent container according to claim 1 , wherein a thickness of the thin-walled part falls within a range of 0.03<t 1 <0.1 mm, a thickness of the thick-walled part falls within a range of 0.06<t 2 <0.2 mm, a width of the thin-walled part falls within a range of 0<w≦1 mm, and a width of the thick-walled part falls within a range of 0<w≦1 mm.

6. The test reagent container according to claim 1 , wherein the discharge channel is formed eccentrically in any one direction from a center axis of the container toward a peripheral wall side.

7. The test reagent container according to claim 1 , wherein a flange member is formed on an upper end of the peripheral wall part in a projecting manner, the film is attached onto an upper surface of the flange member so as to seal a container opening part.

8. The test reagent container according claim 7 , wherein an annular projecting part is formed on a lower surface of the flange member around the peripheral wall part.
