Is it permissible to break off the top of the glass oil vials on yom tov? The vial already contains the oil and wick, and will not be reused once the light goes out. Picture of an example is attached.
We are not allowed to open such a vile on yom tov. The reason is because when the vile is sealed it is essentially unusable nd not considered a kli, and when the top is cracked off it becomes a useable kli and therefore it is considered boneh, which is not permitted on yom tov. Therefore they should be opened before shabbos and yom tov.
