Abstract: A connector system providing a releasable, liquid-tight seal for a fluid system is provided. The system includes a female connector, having a cylindrical opening, and a male connector, having a tubular end section, which is to be inserted in an insertion direction into the cylindrical opening. Inside the tubular end section, a fluid passage is formed. On an outer circumferential surface of the tubular end section, annular protrusions are integrally formed. When the tubular end section with the annular protrusions is inserted into the cylindrical opening, the intermediate protrusion and the rear protrusion each form a press-fit with the inner circumferential surface of the cylindrical opening, whereby a liquid-tight seal between the male connector and the female connector is generated.

Abstract: The invention relates to a system with a seal between a manifold and a liquid container in which a sealing without an elastomer material is used, wherein the sealing properties of the seal are independent of the rotational position of the manifold in relation to the container

Abstract: A waste disposal system for the disposal of consumables through a waste chute into a waste container includes a waste chute having a first opening and a second opening, wherein the first opening is situated outside the waste container and the second opening opens toward the waste container. The first opening and the second opening are arranged at a first distance from one another, wherein the waste chute includes a plurality of self-resetting lamellae for the partial or complete closure of the openings. The lamellae form at least two lamella annuli arranged at a second distance above one another, wherein at least one first lamella annulus closes the first opening and at least one second lamella annulus closes the second opening, and the second distance between the lamella annuli is at least one third, preferably at least half and particularly preferably at least three quarters of the first distance.
