A container with a manual pump wherein, with the purpose of ensuring normal, smooth pouring-out of the contained liquid by preventing the outside air drawn into the container for prevention of negative pressure in a container body from entering a bypass pipe during the use of the container in its inverted position, a changeover valve (20) by which the supply of the contained liquid to a manual pump (1) is switched in response to switching between the erect and inverted positions of a container body (50), thereby making it possible to pour out the contained liquid under pressure even in the inverted position, and wherein the opening in a passage inside the container body (50) to lead the outside air into the container body (50) for prevention of negative pressure is positioned in the rear of a cap body (40), the changeover valve (20) being inclined forwardly downward and mounted in the lower portion of the cap body (40), so that the outside air in the contained liquid rising in bubbles is kept away from a through-hole (26) in the changeover valve (20) provided for the suction of the contained liquid, and the placement of the changeover valve (20) on the valve seat for check valve function is stabilized and made easier to secure. <IMAGE> |
