Mishnah 1א׳

כָּל יְדוֹת הַכֵּלִים שֶׁהִכְנִיסָן שֶׁלֹּא כְדַרְכָּן, אוֹ שֶׁהִכְנִיסָן כְּדַרְכָּן וְלֹא מֵרְקָן, אוֹ שֶׁמֵּרְקָן וְנִשְׁבְּרוּ, הֲרֵי אֵלּוּ חוֹצְצִין. כְּלִי שֶׁהִטְבִּילוֹ דֶּרֶךְ פִּיו, כְּאִלּוּ לֹא טָבָל. הִטְבִּילוֹ כְדַרְכּוֹ בְלֹא זִבּוֹרִית, עַד שֶׁיַּטֶּנּוּ עַל צִדּוֹ. כְּלִי שֶׁהוּא צַר מִכָּאן וּמִכָּאן וְרָחָב מִן הָאֶמְצַע, אֵינוֹ טָהוֹר עַד שֶׁיַּטֶּנּוּ עַל צִדּוֹ. צְלוֹחִית שֶׁפִּיהָ שׁוֹקֵעַ, אֵינָהּ טְהוֹרָה עַד שֶׁיְּנַקְּבֶנָּה מִצִּדָּהּ. קַלְמָרִין הֶדְיוֹטוֹת, אֵינָהּ טְהוֹרָה עַד שֶׁיְּנַקְּבֶנָּה מִצִּדָּהּ. וְקַלְמָרִין שֶׁל יוֹסֵף הַכֹּהֵן הָיְתָה נְקוּבָה בְצִדָּהּ:

Any handles of vessels which were inserted improperly, or which were inserted properly but not secured, or which were secured but they broke, these thereby interpose [i.e. if they are touching something as is being immersed, they prevent it from being purified]. A vessel that was immersed by way of its mouth [i.e. with its mouth face down] is as though it was not immersed. If one immersed it properly [but] without its bottom rim, [it is not pure] until he tips it to its side [so that it will be fully immersed]. A vessel which is narrow at both ends and wide in the middle is not pure until one tips it on its side. A flask with a sunken mouth is not pure until one punctures it on its side [before immersing it]. The ink jar of a commoner is not pure until one punctures it one its side. And the ink jar of Yosef the Priest was punctured on its side.

Mishnah 2ב׳

הַכַּר וְהַכֶּסֶת שֶׁל עוֹר, הֲרֵי אֵלּוּ צְרִיכִין שֶׁיָּבֹאוּ בָהֶם הַמָּיִם. כֶּסֶת עֲגֻלָּה, וְהַכַּדּוּר, וְהָאֵמוּם, וְהַקָּמֵעַ, וְהַתְּפִלָּה, אֵינָן צְרִיכִין שֶׁיָּבֹאוּ בָהֶם הַמָּיִם. זֶה הַכְּלָל, כֹּל שֶׁאֵין דַּרְכּוֹ לְהַכְנִיס וּלְהוֹצִיא, טוֹבְלִים סְתוּמִים:

A leather pillow or cushion require [if one is immersing them to be purified] that the water enter into them. A round cushion, or a [leather] ball, or a shoemakers last, or an amulet or a tefillah [singular of tefillin] do not require that the water enter into them. This is the general rule: anything into which things are not normally inserted and removed may be immersed while sealed [and does not require that the water enter into it].
