APPARATUS FOR STORING AND DEPOSITING LIQUID PREPARATIONS Russian patent published in 2014 - IPC A61M35/00 A45D34/04 

FIELD: chemistry.

SUBSTANCE: apparatus has a hollow housing with an opening in form of a spout in which is inserted a porous rod which is directed by one end into the cavity of the housing and protrudes outside by the other end, an adapter which tightly grips the porous rod, and a sealing cap which is in contact with part of the housing in which the porous rod is inserted. The apparatus is further provided with a bushing which is fitted in the spout of the housing between inner surface of the spout and the adapter, and has a flanged edge which rests on the top end of the spout of the housing, and the sealing cap has a stepped inner surface, wherein the steps of the inner surface are horizontal and are provided with an annular protrusion designed to be mated with the top end of the surface of the flanged edge of the bushing. The diameter of the lower part of the inner surface of the sealing cap mated with the outer surface of the spout of the housing is greater than the diameter of the top part on the width of the steps, and the outer diameter of flanged edge of the bushing is not greater than the outer diameter of the spout of the housing. The top part of the bushing is cylindrical and the lower part of the bushing is in form of a truncated cone, wherein the outer diameter of the top part of the bushing matches the inner diameter of the spout of the housing, and the inner diameter of the lower part of the bushing is not greater than the outer diameter of the adapter. In the top part of the outer surface of the housing at the base of the spout, there is an annular ledge with a horizontal top part designed to support the lower end of the sealing cap.

EFFECT: disclosed apparatus has higher air-tightness, enables to determine the presence of a preparation therein, enables easier removal of the sealing cap, is easy to manufacture and assemble.
