Abstract: A closure with a push type opener and a device for automatically keeping slit sealing member inside the cloture. The closure includes a at an inlet of a container, a cutting region provided at the closure body and sealing the inlet of the container or the closure body as a hemispherical region descends by a pressing method, and a device having a function of keeping the slit sealing member therein. The sealing member can be easily by touching it by hand, and thus, a content of a container can be hygienically taken. In addition, content separately stored in the container and in the closure can be simply mixed for use.

Abstract: Disclosed is a cap (20) provided with a push type opener. The cap includes a cap main body (21) detachably connected to an entrance of a container (10), and an opener (30) provided on the cap main body (21) such that the opener (30) moves down by user's push-type operation so as to open a sealing member (15) provided on the entrance of the container (10) or in the cap main body (21) for sealing the container (10). The sealing member (15) is simply removed using the opener (30) without direct contact by a user's hand, thus allowing contents in the container (10) to sanitarily flow out and causing contents in the container (20) cap to be conveniently mixed with the contents in the container (10).

Abstract: The present invention relates to an agitator for suspension polymerization having a more improved structure in effect in contrast to the earlier agitator. The present invention also relates to an improved suspension polymerization method of vinyl chloride using a polymerization reactor equipped with that agitator, by which vinyl chloride resin having excellent quality can be prepared with a diminution of the number of fish eyes which cause many problems such as deterioration of the processed article, low productivity, etc.
