Abstract
A liquid container such that the liquid received in it will not easily spring out from its tip even if it is wrongly operated, comprises a tank portion for receiving a liquid, a knock bar stretching axially movably within the tank portion which is designed to have on its axial tip portion a pump shelf portion whose diameter have been enlarged, an induction bar fixed into the tip of the knock bar, a brush provided on the tip side of the induction bar, and a spring for always energizing the above knock bar and induction bar rearward. On the internal periphery surface of the above tank portion, a plurality of ribs are formed which stretch axially and on top of which the above pump shelf portion can slide, the internal periphery surface ahead of the ribs is at the same level as and continuous with the top face of the ribs and designed as a diameter-reducing portion where the pump shelf portion can slide. The pump shelf portion slidably touches the ribs when it is not biased.
