Thereby, the identification label L of the rear reagent container 2 can be easily visually recognized while reducing the width of the reagent container set S.

(Connecting member)
Next, the connecting member 3 will be described in detail. 4A is an explanatory plan view of the connecting member 3 shown in FIG. 1, and FIG. 4B is an explanatory front view thereof.
The connecting member 3 includes a first engagement portion 20 that engages with the container mouth portion 5 of the first reagent container 1, a second engagement portion 21 that engages with the container mouth portion 7 of the second reagent container 2, A connecting portion 22 that connects the first engaging portion 20 and the second engaging portion 21, and a projection 23 that is provided in the first engaging portion 20 and serves as a first restricting portion that restricts the rotation of the first reagent container 1. And a protrusion 24 as a second restricting portion that is provided in the second engaging portion 21 and restricts the rotation of the second reagent container 2. The connecting member 3 is made of a hard material, and the thickness D of the connecting member 3 is about 3.5 mm. As the hard material, it is integrally formed of a synthetic resin such as polypropylene, polyethylene or acrylic.

The first engaging portion 20 and the second engaging portion 21 are both formed in a semi-annular shape and engage with the cylindrical engaged portions 14 and 15 of the container mouth portions 5 and 7. The inner diameter Ri of the semi-annular engaging portions 20 and 21 is slightly larger than the outer diameter Ro (see FIG. 3A) of the cylindrical engaged portions 14 and 15. The engaged portions 14 and 15 are cylindrical, the engaging portions are semi-annular, and the inner diameter Ri of the engaging portions 20 and 21 is slightly larger than the outer diameter Ro of the engaged portions 14 and 15. As a result, the engaging portions 20 and 21 engage with the container mouth portions 5 and 7 in a state where the reagent containers 1 and 2 are rotatable. However, in the present embodiment, since the connecting member 3 includes the protrusions 23 and 24 as restricting portions that restrict the rotation of the reagent containers 1 and 2, the rotation of the reagent containers 1 and 2 is limited to a very small range. (Regulated)
The interval w between the openings of the semi-annular engaging portions 20 and 21 (between the end E1 and the end E2 in this embodiment) is made smaller than the outer diameter Ro of the engaged portions 14 and 15. ing.

  In the present embodiment, the semi-annular engaging portions 20 and 21 are connected by the connecting portion 22 so that the opening portions face the same direction.

The end portions E1 to E4 of the semi-annular engagement portions 20 and 21 are rounded by being subjected to R processing. For this reason, when the engaging portions 20 and 21 are pressed against the engaged portions 14 and 15, the engaged portions 14 and 15 enter inside the openings of the engaging portions 20 and 21, and the opening is expanded. Therefore, the connecting member 3 can be smoothly attached to the cylindrical engaged portions 14 and 15 of the container mouth portions 5 and 7 of the reagent containers 1 and 2.
Moreover, since the hook-shaped stoppers 16 and 17 are provided at the front end side of the cylindrical engaged portions 14 and 15, the axial direction of the connected connecting member 3 (the axial direction of the cylindrical container mouth portion). ) Movement can be suppressed.

  The protrusions 23 and 24 are provided at the peripheral edge portions of the semi-annular engaging portions 20 and 21 so as to protrude downward at positions opposite to the openings of the engaging portions 20 and 21. The protrusion height h of the protrusions 23 and 24 from the engaging portions 20 and 21 is such that the protrusions 23 and 24 are open when the connecting member 3 is attached to the container mouth portions 5 and 7 of the reagent containers 1 and 2. The height is set so as to be able to come into contact with the peripheral edges of the base portions 8a and 9a. Thus, even when the reagent containers 1 and 2 are about to rotate when the reagent container set S is handled, the protrusions 23 and 24 come into contact with the peripheral edges of the base portions 8a and 9a of the open state holding portions 8 and 9, so that the rotation is Limited (restricted) to a very small range. Therefore, it becomes easy to handle the two reagent containers 1 and 2 as a single unit. Moreover, the identification label L affixed to each reagent container 1 and 2 can always be made to face in the same direction, and the possibility that the wrong reagent may be used can be eliminated.

  When the connecting member 3 is attached to the container mouths 5 and 7 of the reagent containers 1 and 2, the openings of the semi-annular engaging portions 20 and 21 are pressed against the cylindrical engaged portions 14 and 15. The opening dimension w of the opening portions of the semi-annular engaging portions 20 and 21 is smaller than the outer diameter Ro of the engaged portions 14 and 15, but the engaged portions 14 and 15 are pressed against each other. The opening is expanded and deformed to allow passage of the engaged portions 14 and 15. Then, the engaged portions 14 and 15 pass through the opening, and the engaging portions 20 and 21 engage with the engaged portions 14 and 15. Once the engaging parts 20 and 21 and the engaged parts 14 and 15 are engaged, the semi-annular engaging parts 20 and 21 return to their original shapes, so the openings of the semi-annular engaging parts 20 and 21 are opened. The opening dimension w of the part becomes smaller than the outer diameter Ro of the engaged parts 14 and 15, and the cylindrical engaged parts 14 and 15 are prevented from coming off from the semi-annular engaging parts 20 and 21.

Next, a usage example of the reagent container set S of the present invention will be described based on the reagent container set S according to the embodiment shown in FIG.
