Zusammenfassung: | PROBLEM TO BE SOLVED: To improve usability of a pump type discharge container provided with a suction hole for taking in outside air to a nozzle head, and more specifically, to prevent suction of water adhering to the outer surface of the container when the container is restored after discharging a content fluid.SOLUTION: In a pump type discharge container provided with a suction hole for taking in outside air to a nozzle head, a flexible diameter-reduced cylindrical portion which is inclined downward in an inside direction is provided integrally at a lower end of an outer cylindrical portion of the nozzle head of a double cylinder structure. A gap between a base cap and the nozzle head is blocked by bringing the diameter-reduced cylindrical portion into slidable-contact with the outer surface of a cylindrical portion which becomes a guide stem of the base cap at the lower tip end of the diameter-reduced cylindrical portion. Since water adhering to the outer surface of the container when pushing down the nozzle head is scraped off by the diameter-reduced cylindrical portion, thereafter, when the push-down of the nozzle head is released and the container is restored, suction of the water adhering to the outer surface of the container into the container does not occur, and thereby usability as the pump-type discharge container is improved significantly.
【課題】 ノズルヘッドへ外気を取り込むための吸気孔が設けられたポンプ式吐出容器における使用性の改善、より具体的には、内容液の吐出後に容器を復元する際の容器外面に付着した水の吸い込みを防止する。【解決手段】 ノズルヘッドへ外気を取り込むための吸気孔が設けられたポンプ式吐出容器において、二重筒構造のノズルヘッドの外側の筒状部分の下端へと、下方内側方向に傾斜した可撓性の縮径筒状部分を一体に設け、この縮径筒状部分の下方先端においてベースキャップのガイドステムとなる筒状部分の外面と摺接させることによって、ベースキャップとノズルヘッドとの隙間が塞がれるとともに、ノズルヘッドの押し下げの際に容器外面に付着した水が該縮径筒状部分によって掻き落とされるため、その後、ノズルヘッドの押し下げが解除されて容器が復元する際に、容器外面に付着した水の容器内への吸い込みが起こらず、ポンプ式吐出容器としての使用性が著しく改善される。【選択図】 図1 |
