Case for liquid state cosmetics

A case for liquid state cosmetics, the case comprising:

• a case body provided with a content storage part in which the liquid content is stored;
• a shoulder unit coupled to close an upper portion of the case body and provided with an inflow part having a content inflow hole in a center thereof;
• a piston unit disposed in the case body to move according to discharge of the content;
• a pumping unit inserted into the inflow part and connected to the content inflow hole to discharge the content through pumping action due to elasticity;
• and
• a button unit elevatably coupled to an upper portion of the shoulder unit and connected to the pumping unit and having an outlet hole, through which the content is discharged, at a center thereof, the button unit operating the pumping unit to discharge the content to the outlet hole by the pumping action of the pumping unit,
• wherein the pumping unit comprises:
• a pumping member which is made of an elastic material so that the content is discharged through the pumping action such as compression and expansion due to the elasticity and through which a content moving passage connected to the content inflow hole passes through the inside thereof;
• a valve member integrated with the pumping member to open a lower side of the content moving passage communicating with the content inflow hole;
• a nozzle member inserted into an upper portion of the pumping member to open and close an upper side of the content moving passage while coming into contact and non-contact with the pumping member when the pumping member is elastically deformed, thereby discharging the content;
• and
• a pumping cap disposed below the button unit and coupled to the upper portion of the pumping member and having a discharge hole connected to a nozzle hole of the nozzle member at a center thereof.
