Abstract: The present invention provides a sealing plug for liquid-tight sealing off hollow flotation elements of a strip for a cover of a liquid-filled container. The sealing plug comprises an end plate and at least two protrusions extending from the end plate. The at least two protrusions comprise at least two lips. The end plate and the protrusions are formed of a first material and the lips are formed of a second material, the first material being harder than the second material. The at least two lips extend in a first direction including an angle between +/?90° and +/?180° with the direction in which the sealing plug is pushed into the hollow flotation elements and preferably have decreasing height starting from the end plate toward a free extremity of the protrusion.

Abstract: The invention relates to a tablet dispenser, including a dispenser housing, a replaceable tablet package to be accommodated in the housing, an adjustable periodicity indicator and a single tablet dispensing aperture in the dispenser cover. The tablet package includes a cover, rotatably connected to the bottom portion of the package and provided with an opening which, upon use of the dispenser, is in alignment with the tablet dispensing aperture. The dispenser further includes a locking device to compel joint rotational movement of periodicity indicator and package bottom portion, and an operating member to effect stepwise rotation of the package bottom portion relative to said package cover.
