Abstract: The present invention provides a pet toilet which can suppress breakage of a sheet and can be easily replaced and can be used comfortably by an owner. A pet toilet comprising: a strip-shaped processing sheet for processing excrement of pet; an unwinding roller for unwinding the processing sheet; a pedestal on which the processing sheet is laid; a excrement collecting unit for collecting the excrement; wherein the excrement collecting section including: a winding roller for collecting urine; a feces collecting section for collecting feces.

Abstract: A nose mask including mask portions that can be inserted from nares into a nasal vestibule to fix the mask portions to a nasal cavity of a user. Each of the mask portions includes a cellulose sponge and a pair of perforated silicon rubber members arranged on opposite sides of the cellulose sponge. The mask portions are secured on ends of an axle by a cap and stopper by sandwiching the mask portions between the cap and stopper.

Abstract: A nose mask having either one of several types of mask parts with different functions selectively fitted to an installation shaft, usable without impairing the attractiveness of a nose, and formed so that, when the installation shaft is inserted from nostrils into nose vestibules a nasal septum is held so as to install the mask part. The mask part is engaged with the tips of the installation shaft by caps and stoppers, and cellulose sponges and filters are arranged alternately with each other. The mask parts can be classified into a plurality of groups according to functions, i.e those for underwater action without gas permeability and water permeability, those having fine-mesh filters formed of fiber material with gas permeability and excellent hygroscopicity and capable of filtering contaminated air, and those allowing liquid such as chemicals to be impregnated therein.
