Abstract: A self-service low temperature cooling cabinet for easily spoilable food and/or edible products, especially ice cream, with an easily accessible front withdrawing opening and two cooling units or groups of cooling units comprising a ventilator and an evaporator. These cooling units or groups of cooling units convey the cooling air in a circuit over the goods to be cooled and subsequently again to the evaporators of the cooling units or group of cooling units. Above and below a display chamber confined by the withdrawing opening and a servicing opening as well as by a closed air impermeable bottom and ceiling wall there is respectively provided an evaporator cell having respectively associated therewith an evaporator or a group of evaporators.

Abstract: In a sealing head for vacuum sealing a cap-shaped cover of relatively soft inelastic permanently deformable material with a sealing insert to a container of at least substantially rigid material provided with a beading on its outer face in the vicinity of its aperture, which sealing head has a flange plate, a head plate carrying a ring of pressure fingers projecting downwards and elastically yielding in a radial direction, which pressure fingers are surrounded by a rubber sleeve and also a steel sleeve placed over the latter, and a pressure plate carried by an axial shaft, held by the pressure fingers and displaceable inside these together with the shaft against the action of a spring, the improvement comprising the head plate together with the pressure fingers carried by it being displaceable relative to the flange plate by a limited amount on the shaft against the action of resilient means and enclosed by a rigid external shell connected to the flange plate and forming underneath the free end of the pressur
