CAPSULE

摘要

There is provided a capsule in which large and sharp burr is not easily formed in such case of unsealing. This capsule comprises a cap portion 1, a skirt portion 2, and a tearable guarantee strip 3. Weakening lines 4 and 5 are formed at a boundary between the tearable guarantee strip 3 and the cap portion 1, and at a boundary between the tearable guarantee strip 3 and the skirt portion 2. The weakening line 5 comprises linear compressed part 8 and saw-tooth-like compressed parts 9. The saw-tooth-like compressed parts 9 are formed so as to serrate from the linear compressed part 8 to the tearable guarantee strip 3 side. The saw-tooth-like compressed parts 9 may be also formed so as to serrate from the linear compressed part 8 to the skirt portion 2 side. The weakening line 5 may be also formed of a plurality of circular arc compressed parts each drawing an arc on the tearable guarantee strip 3 side and disposed with a certain distance. The weakening line 5 may be also formed of circular arc holes instead of circular arc compressed parts. The weakening line 4 may also comprise either linear compressed part 8 and saw-tooth-like compressed parts 9 or circular arc compressed parts only.
