It is 7. that the purpose of the present invention, which provides one kind containing chlorphenamine and/or its salt and pH in what,In 0 or more liquid preparation, it is able to suppress chlorphenamine and/or its salt absorption what container, thus the technology stably kept. Chlorphenamine and/or its salt are contained to what and pH is 7.For 0 or more liquid preparation, container as receiving, by using the resin for containing polybutylene terephthalate (PBT) as the resin that inner wall surface thereof (pouring out the wall surface etc. that pour out mouth opposed in the wall surface and/or cap of the inner space in portion with the portion that pours out) is made, it is able to suppress the absorption of chlorphenamine and/or its salt to the inner wall, to stably keep the content of the chlorphenamine and/or its salt in liquid preparation.本發明的目的在於提供一種在含有氯苯那敏和/或其鹽、且pH爲7.0以上的液體製劑中，能夠抑制氯苯那敏和/或其鹽吸附於容器，從而穩定地保持的技術。對於含有氯苯那敏和/或其鹽、且pH爲7.0以上的液體製劑而言，作爲容納的容器，通過採用含有聚對苯二甲酸丁二醇酯的樹脂作爲製成其內壁面(傾出部的內部空間的壁面和/或蓋部中與傾出部的傾出口對置的壁面等)的樹脂，能夠抑制氯苯那敏和/或其鹽向該內壁面的吸附，從而穩定地保持液體製劑中的氯苯那敏和/或其鹽的含量。
