Abstract: FIELD: medicine; veterinary medicine. 
     SUBSTANCE: invention relates to medicine and veterinary medicine and can be used for waste collection. The loading device-insert of a container for medical waste contains a cylindrical body designed to be placed in an opening of a plastic or cardboard container for medical waste. The body is equipped with a flange for abutting against the outer surface of the container and a cylindrical sleeve connected to the body by means of a threaded connection. The sleeve is provided with a flange at the end for abutting against the inner surface of the container to ensure compression of the surface of the container between the sides of the cylindrical body and the sleeve. The outer cylindrical surface of the body and the inner cylindrical surface of the sleeve, intended to interact with each other by means of a threaded connection, are provided with a pair of opposite oblique longitudinal protrusions serving as a threaded connection. The lower surface of each oblique longitudinal projection of the cylindrical body is provided with an oblique latching projection located at the end of the oblique longitudinal projection of the body. The latch protrusion is made of trapezoidal shape with an outer inclined lower side. The inclination of the underside of the latch-projection is directed from the edge of the inclined longitudinal projection of the cylindrical body in such a way that the smaller vertical side of the latch-projection is located closer to the end of the inclined longitudinal projection of the cylindrical body than its larger vertical side. On the inner cylindrical surface of the sleeve along its perimeter, inclined barrier projections are made, located below the inclined longitudinal projections of the sleeve parallel to them. The bushing barriers are arranged in groups. The number of groups of barrier projections of the sleeve corresponds to the number of oblique longitudinal projections made on the inner surface of the sleeve. The extreme barrier protrusion of each group is located not further than the edge of the corresponding oblique longitudinal protrusion of the sleeve, under which it is located. Each barrier protrusion of the sleeve is trapezoidal. The slope of the upper side of each barrier protrusion is directed from the edge of the oblique longitudinal protrusion of the cylindrical sleeve such that the large vertical side of each barrier protrusion is closer to the edge of the oblique longitudinal protrusion of the sleeve than its large vertical side. The distance between adjacent barrier protrusions of the sleeve is not less than the width of the housing latch to ensure unobstructed placement of the housing latch between adjacent barrier protrusions of the sleeve. The latch-latch of the body and the barrier projections of the sleeve are vertically spaced from each other at a distance at which the lower outer inclined side of the latch-latch of the body is provided to slide along the outer surface of the upper inclined side of the barrier projections of the sleeve during the rotational-translational movement of the sleeve when it is screwed onto the body. 
     EFFECT: increasing the reliability of the loading device-insert of the container for medical waste during operation and fixing it on the package by ensuring a reliable connection of the elements of the device-insert, simplifying the design, ease of fastening.
