Description

  The present invention relates to a discharge container, and more particularly, to a discharge container including a stopper that prevents the discharge head from being pushed down.

  Various types of discharge containers are known in which the discharge liquid of a pump attached to the container body is moved up and down to discharge the stored liquid from the nozzles of the discharge head. Various types of stoppers have been proposed to prevent inadvertent depression of the ejection head during use.

  These stoppers are generally detachably fitted between the mounting cap and the discharge head, for example, on the outer periphery of the guide cylinder standing on the mounting cap or on the outer periphery of the stem of the operating member. Although the effect of preventing the ejection head from being pushed down is great, there is a disadvantage that there is no way to confirm even if the stopper is removed during distribution or display.

  Therefore, the present applicant has proposed a discharge container with a stopper that can eliminate such inconveniences and that keeps a simple structure as much as possible and prevents fraudulent acts during distribution and display. (For example, see Patent Document 1)

  The discharge container of Patent Document 1 is a discharge container having a shoulder cover (mounting cap) for attaching a pump having a discharge nozzle attached to the mouth of the container body, and the shoulder cover has a discharge nozzle on its upper wall. The guide tube and the protective cover are erected, and the surface of the stopper engaged with the guide tube is covered with the protective cover.
