垃圾桶，又名廢物箱或垃圾(ji)箱(xiang)，就是(shi)裝放垃(la)圾(ji)的(de)地方。垃(la)圾(ji)桶多數以(yi)金屬(shu)或塑膠制，用時放入(ru)塑料袋，當垃(la)圾(ji)一多便可扎起袋丟掉。多數垃(la)圾(ji)桶都有蓋以(yi)防垃(la)圾(ji)的(de)異味四(si)散，有些垃(la)圾(ji)(ji)桶可(ke)以(yi)以(yi)腳踏開(kai)啟(qi)。垃(la)圾(ji)(ji)桶是人們(men)生(sheng)活中“藏污納(na)垢”的(de)容(rong)器，也(ye)是社會(hui)文化的(de)一種折射(she)。家居(ju)的(de)垃(la)圾(ji)(ji)桶多數放于廚(chu)(chu)房(fang)，以(yi)便放置廚(chu)(chu)余。垃(la)(la)(la)圾(ji)(ji)(ji)桶(tong)(tong)(tong)(tong)(tong)就(jiu)(jiu)(jiu)使用場(chang)合(he)可(ke)分(fen)為(wei)公(gong)共垃(la)(la)(la)圾(ji)(ji)(ji)桶(tong)(tong)(tong)(tong)(tong)和(he)家庭垃(la)(la)(la)圾(ji)(ji)(ji)桶(tong)(tong)(tong)(tong)(tong)。就(jiu)(jiu)(jiu)盛放垃(la)(la)(la)圾(ji)(ji)(ji)形式可(ke)分(fen)為(wei)獨(du)立垃(la)(la)(la)圾(ji)(ji)(ji)桶(tong)(tong)(tong)(tong)(tong)和(he)分(fen)類垃(la)(la)(la)圾(ji)(ji)(ji)桶(tong)(tong)(tong)(tong)(tong)。就(jiu)(jiu)(jiu)加工材料可(ke)分(fen)為(wei)塑料垃(la)(la)(la)圾(ji)(ji)(ji)桶(tong)(tong)(tong)(tong)(tong)、不銹(xiu)鋼垃(la)(la)(la)圾(ji)(ji)(ji)桶(tong)(tong)(tong)(tong)(tong)、陶瓷(ci)垃(la)(la)(la)圾(ji)(ji)(ji)桶(tong)(tong)(tong)(tong)(tong)、木(mu)質垃(la)(la)(la)圾(ji)(ji)(ji)桶(tong)(tong)(tong)(tong)(tong)、水泥垃(la)(la)(la)圾(ji)(ji)(ji)桶(tong)(tong)(tong)(tong)(tong)和(he)紙漿垃(la)(la)(la)圾(ji)(ji)(ji)桶(tong)(tong)(tong)(tong)(tong)等等。就(jiu)(jiu)(jiu)開(kai)啟方式有敞口式、揭(jie)蓋式、踩踏開(kai)蓋、感應式（紅外線）等。

小編建議大家在選購廚房垃(la)圾(ji)桶(tong)時最好選(xuan)擇帶(dai)蓋(gai)的垃(la)圾(ji)桶(tong)。市(shi)面(mian)上(shang)還有帶(dai)蓋(gai)和不帶(dai)蓋(gai)的兩(liang)種垃(la)圾(ji)桶(tong)。廚(chu)房(fang)因為帶(dai)水(shui)分的垃(la)圾(ji)多，易散(san)發氣(qi)味，最好選(xuan)帶(dai)蓋(gai)的。丟(diu)進垃(la)圾(ji)桶(tong)前(qian)須(xu)瀝去(qu)水(shui)分，隨時封口。不帶蓋(gai)的垃圾桶可放(fang)一些干性、沒有(you)氣(qi)味的垃圾，適合臥室或客廳。干性垃圾中的廢(fei)電池、廢(fei)日光燈管、廢(fei)水(shui)銀溫度計(ji)、過期藥品等有(you)害垃圾，也需(xu)要分(fen)裝(zhuang)并(bing)密封。
