TUBE-TYPE CONTAINER HAVING CHECK FUNCTION
First Claim
1. A tube-type container having a check function, comprising:
- a body (100) containing contents in liquid state;
an extension tube (200), located at the upper end of the body (100), having a passage (210) through which the contents passes from the body (100);
a discharge cap (300), heretically connected to the upper end of the extension tube (200), forming a discharge passage (310), through which the contents are discharged to the outside, at its upper end;
a cover (400), screw-coupled to the outer surface of the extension tube (200), preventing foreign matter from flowing into the body (100);
wings (320) that are inwardly protrudently formed on the inner wall of the discharge cap (300) and regularly spaced apart from each other, a space formed between the wings (320);
a fixing member (500) fitted into the wings (320);
an operating member (600) whose upper end is inserted into the fixing member (500) and whose lower end forms a closing plate (610) for closing the passage (210); and
a spring (700) placed between the operating member (600) and the fixing member (500) for allowing the operating member (600) to elastically tightly close the passage (210).

Abstract
A tube-type container having a check function is filled with liquid contents irrespective of the magnitude of viscosity, prevent air flowing inside the container when the liquid contents are used. The container includes a body, an extension tube, a discharge cap, a cover, wings, a fixing member, an operating member, and a spring. The wings are inwardly protrudently formed on the inner wall of the discharge cap and regularly spaced apart from each other, a space formed between the wings. The fixing member is fitted into the wings. The operating member is configured in such way that its upper end is inserted into the fixing member and its lower end forms a closing plate for closing the passage. The spring is placed between the operating member and the fixing member for allowing the operating member to elastically tightly close the passage.
