Abstract

A compound container which is comprised of a container main body 2 forming a first accommodation chamber 20 and an auxiliary container 3 forming a second accommodation chamber 30, wherein a mounting part 22 on which the auxiliary container 3 is mounted is provided in the container main body 2 and a cutting part 221 which cuts a second accommodation chamber partition wall 30a which partitions part of the second accommodation chamber 30 formed in the auxiliary container 3 is formed, and when the auxiliary container 3 is mounted on the container main body 2, the second accommodation chamber partition wall 30a is cut, whereby the first accommodation chamber 20 and the second accommodation chamber 30 are intercommunicated. As a result, if contents which are needed to be heat-treated are heated while keeping the state where the contents are sealed within the container, the contents which are sealed in a plurality of accommodation chambers formed in the container can be mixed while keeping the contents being isolated from the outside environment by effectively preventing the contents to be heated from leaking outside as well as by preventing deterioration of sealing performance.

Claims

1. A compound container which at least comprises a container main body forming a first accommodation chamber and an auxiliary container forming a second accommodation chamber,

wherein a mounting part on which the auxiliary container is mounted is provided in the container main body and a cutting part which cuts a second accommodation chamber partition wall which partitions part of the second accommodation chamber formed in the auxiliary container is formed, and

when the auxiliary container is mounted on the container main body, the second accommodation chamber partition wall is cut, whereby the first accommodation chamber and the second accommodation chamber are intercommunicated.

2. The compound container according to claim 1, wherein a contents outlet port is provided in the container main body and an opening pouring element to be mounted on the contents output port is comprised,

the opening pouring element is provided with a cutting part which cuts a first accommodation chamber partition wall which partitions part of the first accommodation chamber formed in the container main body, and

when the opening pouring element is mounted on the container main body, the first accommodation chamber partition wall is cut to allow the contents to be taken out from the first accommodation chamber.

3. The compound container according to claim 2, wherein a narrowing part which narrows the area of the opening of the pouring port is formed on the front end side of the pouring port formed in the opening pouring element, and a truncated cone-shaped concave part is formed on the front end of the pouring port.

4. The compound container according to claim 2, wherein the opening pouring element is provided with an outer cylindrical part in which a pouring port is formed, the cutting part which is installed on the inside of the outer cylindrical part, and a filter which is retained between the outer cylindrical part and the cutting part.

5. The compound container according to claim 2, which further comprises a sealing element which is detachably attached to the mounting part provided in the container main body to seal the first accommodation chamber,

the sealing element is removed from the mounting part when the auxiliary container is attached to the container main body, and

when the container is disposed, the sealing element is attached to the pouring port of the opening pouring element to seal the container, and prevents the leakage of the contents remaining in the container.

6. The compound container according to claim 2, which further comprises a protection element which is detachably attached to the content output port provided in the container main body.

7. The compound container according to claim 1, wherein the container main body has a trunk part formed of a flexible material and the mounting part is formed separately from the trunk part.

8. The compound container according to claim 1, wherein the auxiliary container further comprises a trunk part of which the one end side serves as an opening part and the other end side is blocked by the second accommodation chamber partition wall and a lid which is installed on the opening part and serves to seal the second accommodation chamber, and the lid has a part which is in close contact with the inner peripheral surface of the trunk part.

9. The compound container according to claim 8, wherein circular projections which contact the front end surface of the peripheral edge of the opening part of the trunk part of the auxiliary container are formed at a corresponding position on the side of the lid.

10. The compound container according to claim 8, wherein a sealing cylinder is formed on the outer peripheral side of the cutting part formed on the mounting part, whereby, when the auxiliary container is mounted on the mounting part for cutting the second accommodation chamber partition wall, the cutting part is in close contact with the inner peripheral surface of the trunk part, and the sealing cylinder is allowed to be in close contact with the outer peripheral surface of the trunk part of the auxiliary container.

11. The compound container according to claim 1, wherein a sample which has been collected from a subject is added to a reagent accommodated within the second accommodation chamber, the contents are treated together with the auxiliary container, the auxiliary container is mounted on the container main body, and the contents in the second accommodation chamber are flown into the first accommodation chamber, followed by stirring and mixing, thereby to allow all or part of unnecessary substances to be adsorbed in an adsorbent accommodated in the first accommodation chamber.

12. The compound container according to claim 2, wherein a sample which has been collected from a subject is added to a reagent accommodated within the second accommodation chamber, the contents are treated together with the auxiliary container, the auxiliary container is mounted on the container main body, and the contents in the second accommodation chamber are flown into the first accommodation chamber, followed by stirring and mixing, thereby to allow all or part of unnecessary substances to be adsorbed in an adsorbent accommodated in the first accommodation chamber, and

the opening pouring element is attached to the container main body to cut the first accommodation chamber partition wall, thereby allowing a sample preparation liquid which has been prepared to be poured from a pouring port formed in the opening pouring element.

13. The compound container according to claim 12, which further comprises a positioning means which positions, when the sample preparation liquid is poured from the pouring port and dripped to a predetermined dropping container, the front end of the pouring port which is inserted into the dropping container so that the distance between the front end of the pouring port and the inner bottom surface of the dropping container becomes constant.

14. A pouring method for pouring a predetermined amount of a sample preparation liquid from the compound container according to claim 13, which comprises:

displaying on the dropping container a liquid level line indicating at least the lower limit of the predetermined amount,

after positioning the front end of the pouring port while inserting the pouring port into the dropping container,

squeezing the container main body to allow the sample preparation liquid to be poured until the amount of the liquid which has been poured exceeds the liquid level line showing the lower limit, and

when the liquid level of the sample preparation liquid which has been poured exceeds the front end of the positioned pouring port, while keeping the positioned state, restoring the container main body to suck the sample preparation liquid which has been excessively poured, thereby allowing an adequate amount of a sample preparation liquid to be poured.
