The closing wall 12 is a member that divides the inside of the container body 10 into the first agent storage chamber 13 and the second agent storage chamber 14 in the axial direction, and a circumferential direction is provided between the closing wall 12 and the inner peripheral wall. A communication hole 15 extending in the direction is formed. The first agent storage chamber 13 and the second agent storage chamber 14 communicate with each other through the communication hole 15. The wall portion of the container body 10 is formed with a large diameter portion 16 at the center and small diameter portions 17 and 18 at both ends, and a lid 20 and a rotary lid 30 that correspond to the outer peripheral surfaces of the small diameter portions 17 and 18 at both ends. A threaded portion 19 for screwing together is formed.

As shown in FIGS. 1 and 3, the lid 20 is in the shape of a headed cylinder having substantially the same outer dimensions as the large diameter portion of the container body 10, and has a screw portion 21 on its inner peripheral surface. By engaging with the threaded portion 19 on the outer peripheral surface of the small diameter portion 17, the small diameter portion 17 is screwed into the small diameter portion 17. In addition, the inner cylindrical portion 22 vertically provided on the back surface of the lid 20 is fitted in an opening at one end of the container body 10 in a liquid-tight manner during screwing.

As shown in FIGS. 1 and 3, the rotary lid 30 has a bottomed cylindrical shape having substantially the same external dimensions as the large diameter portion 16 of the container body 10, and has a By engaging the screw portion 31 with the screw portion 19 on the outer peripheral surface of the small diameter portion 18, the screw portion 31 is screwed into the small diameter portion 18 from below. In addition, an inner cylinder 32 is provided upright from the inner surface of the rotary lid 30 so as to slide along the inner peripheral surface of the container body 10 according to the screwing of the rotary lid 30. The inner diameter of the inner cylinder 32 and the outer diameter of the closing wall 12 are set to be substantially equal to each other. When the screwing of the rotary lid 30 is completed, the space between the upper end of the inner cylinder 32 and the closing wall 12 is set. It is kept airtight (the upper end opening of the inner cylinder 32 is sealed by the closing wall 12).

The reverse rotation of the rotary lid 30 forms an open circuit again between the upper end of the inner cylinder 32 and the closing wall 12. The rotary lid 30 retreats for a certain distance, and then the rotary lid 30 is rotated.
