A urinal (pronounced or ) is a sanitary plumbing fixture for urination only, predominantly used by males. It can take the form of a container or simply a wall, with drainage and automatic or manual flushing, or without flush water as is the case for waterless urinals. The different types of urinals, be it for single users or as trough designs for multiple users, are intended to be utilized from a standing position (rather than squatting or sitting). The term may also apply to a small building or other structure containing such fixtures. It can also refer to a small container in which urine can be collected for medical analysis, or for use where access to toilet facilities is not possible, such as in small aircraft, during extended stakeouts, or for the bedridden. While urinals are generally intended for use by males, it is also possible for females to use them. Designers of urinals for women have adopted various approaches: some intending the user to "hover" over the unit, facing away from it, others intending the user to stand facing the urinal, with or without a female urination device. While uncommon due to restroom segregation, it is possible for females to use male urinals.〔() 〕 ==Description== In busy washrooms, urinals are installed for efficiency: compared with urination in a general-purpose toilet, usage is faster because within the room there are no additional doors, no locks, and no seat to turn up; also a urinal takes less space, is simpler, and consumes less water per flush (or even no water at all) than a flush toilet. Urinals also come in different heights, to accommodate tall and short users, men or boys. There are often privacy barriers between the urinals. Public urinals usually have a plastic mesh guard, which may optionally contain a deodorizing urinal deodorizer block or "urinal cake". The mesh is intended to prevent solid objects (such as cigarette butts, feces, chewing gum, or paper) from being flushed and possibly causing a plumbing stoppage. In some restaurants, bars, and clubs, ice may be put in the urinals, serving some of the same purposes as the deodorizing block without dispensing odorous chemicals. The body posture for users of urinals is usually the standing position, except for urinals intended for females which may be used in more of a "hovering" position (partial squat), or even a full squatting position. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「urinal」の詳細全文を読む スポンサード リンク
