Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To prevent dust accumulate at incisions and prevent the dust from reaching the mouth-and-neck part of a container by a method wherein the incisions piercing through from the outside formed with a cutting edge are provided in the plural number at intervals in the circumferential direction at least at one out of two parts including the peripheral part of the top wall and the skirting wall of a synthetic resin container cap. SOLUTION: A container cap 2 is equipped with a circular top wall 4 and a skirting wall 6 hanging down from the circular top wall, and a circumferential break line 8 is formed at the skirting wall 6. The circumferential break line 8 separates a tamper- evident hem part 12 from a main part 10 of the skirting wall 6 by severing a plurality of bridging parts 14. A plurality of incisions 44 extending in the circumferential direction with intervals provided in the circumferential direction are formed by working of a cutting edge piercing through from the outside at the upper part of the skirting wall 6. Thereby, while washing liquid sprayed on the container cap 2 is allowed to permeate through and reach the mouth-and-neck part of the container, dust is effectively prevented from permeating and reaching the mouth-and-neck part of the container.
