Combined pacifying nipple and mouth thermometer device

A combined pacifying nipple and mouth thermometer device comprising a liquid thermometer tube including a temperature displaying main portion and a liquid bulb portion at one end of the main portion, a flexible pacifying nipple including a flexible tubular mouth-piece portion having an outer end and an inner end, a lip abutment flange fixed to said inner end and surrounding the same, the outer end and the inner end of said mouthpiece portion both having apertures aligned longitudinally of the pacifying nipple, the liquid thermometer tube having a part of its main portion extending through said mouth-piece portion and frictionally extending through both apertures such that said liquid bulb portion is located exteriorly of said mouth-piece portion adjacent said outer end and the remaining part of said main portion of said thermometer tube extends exteriorly from the inner end of said mouthpiece portion, an elastic sleeve tightly engages over a substantial portion of the part of said thermometer tube extending within said mouthpiece portion, said elastic sleeve having an outer end disposed short of said liquid bulb portion, the marginal portion of the aperture at the outer end of said mouthpiece portion abutting against said outer end of said sleeve, and a transparent protector tube having an open end removably secured to said abutment flange and surrounding the temperature displaying main portion of said thermometer tube and having a closed end at its outer end engaged over the other end of the thermometer tube and wherein the aperture at the inner end of said mouthpiece portion forms an annular external bead, said inner end engages in a recess made in the aperture of said lip abutment flange, the latter being further integrally formed with an internally threaded sleeve portion axially projecting away from said mouthpiece portion and said protector tube is removably screwed within said internally threaded sleeve portion and abuts said bead and axially compresses the latter to cause the same to tightly engage said thermometer tube to prevent sliding of the thermometer tube relative to said lip abutment flange.
