Rav Shlomo Zalman Auerbach: Disposable Ready Made Neiros Chanukah
There is a machlokes whether you may use a throw away cup for Kiddush on Shabbos. What about Neiros Chanuka, may you use the throw away glasses that come complete with oil and wick inside and are disposed each day?
The Halichos Shlomo (2:15:5) writes that Rav Shlomo Zalman Auerbach was matir L'chatchila. In the footnotes below it explains that the whole question is based on whether it is nice for the mitzva of Chanuka to use a throw away item. Since this throw away item is made special for use on Chanuka Rav Shlomo Zalman holds that it is permissible without any reservation.
The Minchas Yitzchok however holds that the problem with a throw away items is that it may not be considered a Keili. To this Rav Shlomo Zalman says that a Keili is not subject to the criteria of multi-use. The question is looking at the Keili itself is it sufficient to be considered a vessel.
