Abstract

A test container including: at least two accommodation portions each accommodating a liquid and internally provided; a flow path connecting the two accommodation portions to each other at respective upper end positions thereof internally provided; and a flexible film deformable inwards of at least one accommodation portion at a portion forming an upper wall surface of the one accommodation portion, in which the liquid accommodated in the one accommodation portion is fed to the other accommodation portion via the flow path due to deformation of the flexible film towards the one accommodation portion, and a breaking elongation of the flexible film is 100% or more and 600% or less.

First claim

What is claimed is:

1. A test container comprising:
at least two accommodation portions each accommodating a liquid and internally provided;
a flow path connecting the two accommodation portions to each other at respective upper end positions thereof and internally provided; and
a flexible film deformable inwards of at least one accommodation portion at a portion forming an upper wall surface of the one accommodation portion,
wherein the liquid accommodated in the one accommodation portion is fed to the other accommodation portion via the flow path due to deformation of the flexible film towards the one accommodation portion, and
a breaking elongation of the flexible film is 100% or more and 600% or less.

2. The test container according to claim 1 ,
wherein, in a case where a thickness of the flexible film is t μm, a modulus of elasticity of the flexible film is β MPa, and a depth of the one accommodation portion is d μm,
relationships of 0.03≤t/d≤2.5 and
2,000≤β×t≤250,000 are satisfied.

3. The test container according to claim 2 ,
wherein relationships of 0.03≤t/d≤1.8 and
2,000≤β×t≤110,000 are satisfied.

4. The test container according to claim 2 ,
wherein relationships of 0.08≤t/d≤1.0 and
2,000≤β×t≤50,000 are satisfied.

5. The test container according to claim 2 ,
wherein relationships of 0.2≤t/d≤0.4 and
4.000≤β×t≤20.000 are satisfied.

6. The test container according to claim 1 ,
wherein the breaking elongation is 200% to 500%.

7. The test container according to claim 1 , further comprising:
a container main body portion in which a portion forming each of the at least two accommodation portions and the flow path is open; and
an upper lid member including the flexible film,
wherein the at least two accommodation portions and the flow path are internally formed by covering an opening of the container main body portion with the upper lid member.

8. The test container according to claim 7 ,
wherein the upper lid member has flexibility over an entire area.

9. The test container according to claim 1 ,
wherein the flexible film consists of any of a silicone resin, a fluororesin, polyolefin, and polycarbonate.

10. The test container according to claim 1 , comprising:
a first accommodation portion; a second accommodation portion as the one accommodation portion; a third accommodation portion as the other accommodation portion;
a first flow path connecting the first accommodation portion and the second accommodation portion to each other at respective upper end positions thereof; and
a second flow path connecting the second accommodation portion and the third accommodation portion to each other at respective upper end positions thereof.

11. The test container according to claim 10 , comprising:
a liquid return prevention structure which prevents a backflow of the liquid to the first accommodation portion, in a case where the liquid accommodated in the second accommodation portion is fed to the third accommodation portion via the second flow path due to deformation of the flexible film toward the second accommodation portion.

12. The test container according to claim 11 ,
wherein the liquid return prevention structure has a structure in which a height from an inner bottom surface of the second accommodation portion to an inner bottom surface of the first flow path is higher than a height from the inner bottom surface of the second accommodation portion to an inner bottom surface of the second flow path.

13. The test container according to claim 11 ,
wherein the liquid return prevention structure has a structure of the first flow path and the second flow path in which a water contact angle of an inner surface of the first flow path is set to be greater than a water contact angle of an inner surface of the second flow path.

14. The test container according to claim 11 ,
wherein the liquid return prevention structure has a structure of a stepped portion which is provided between the first flow path and the second accommodation portion and which includes two or more steps from an inner bottom surface of the second accommodation portion.

15. The test container according to claim 10 , further comprising:
a chromatographic carrier for performing a nucleic acid test; and
a carrier accommodation portion accommodating the chromatographic carrier.

16. The test container according to claim 10 ,
wherein the first accommodation portion accommodates a first liquid containing magnetic particles,
the second accommodation portion accommodates separated magnetic particles separated from the first liquid, and
the first flow path allows the separated magnetic particles to pass.
