Two genus mixed formulation notes the upward step

摘要

PROBLEM TO BE SOLVED: To provide a container in which a second drug stored in the upper part of a main cylinder drops into a first drug storage compartment in the lower part of the main cylinder to form a mixture drug when a lid screwed on the main cylinder but not permitted to turn to move upward is turned to move downward, and a part of container formed of the main cylinder and lid is pressed to increase the inner pressure of the container, causing the mixture drug in the container to drop out of a spout hole formed on the wall of the main cylinder, and which simplifies a function of preventing the lid being turned against the main cylinder to move upward.;SOLUTION: A spacer 31 supporting the lower end surface of the outer peripheral wall 22 of the lid is formed on the upper surface of the outer periphery of an upward step 12 of the main cylinder. A plurality of elastic pieces 17 are erected from the inner part of the upward step 12 along the inner surface of the spacer 31. Nails 17 formed on the tops of the elastic pieces 17 are made to slide over a plurality of engaging projecting stripes 26, which are formed vertically on the inner surface of the lid outer peripheral wall 22, in a direction of screwing down the lid, and to engage with the stripes 26 in a direction of screwing up, so that the lid is made incapable of screwing up further.;COPYRIGHT: (C)2007,JPO&INPIT
