Abstract: A unitary biological specimen processing apparatus has a bottom (1) and a lid (2) for use in the processing multiple tissues of different sizes of biological and medical specimens, such as tissue samples for microscopy, whereby the plate part (15, 18) of the lid (2) and the plate part (14, 17) of the bottom 81) in the apparatus (1, 2) are perforated and in the form of strainers. The apparatus is in its closed position divided by one or more opposing chamber walls (11, 12) into two or more chambers (9, 10) being formed by mating of the opposing chamber walls. The strainer perforations (16, 19) in the plate part (15, 18) of the lid (2) and the plate part (14, 17) of the bottom (2) in a chamber (9, 10) are of the same dimension, and said dimension is different for at least two of the chambers (9, 10). Thereby it is achieved that the number of different apparatuses to be stored for such processings, can be reduced.

Abstract: Unitary biological processing apparatus for processing specimens therein is described wherein a perforated receptacle member with two arc shaped abutment means and a third hook shaped abutment means is attached through a frangible hinge portion to a perforated lid member with two arc shaped detent means at the two edges of the lid member which are perpendicular to the lid member edge extending along the hinge portion, and a third detent means engageable with the hook shaped abutment means. When the lid member is swung about the hinge the arc shaped engagement means become engaged even before the lid member mates against the receptacle member and the two arc shaped engagement means provide with the third engagement means a three-point lock of the lid member onto the receptacle member.

Abstract: The present invention relates to a valve element for a deformable container for liquid products, such as soap, skin preparations, etc., wherein the valve element is adapted to be located in close proximity to an outlet of the container. The valve element [1] has a yieldable domed section [1b] having at least one central slit or fissure [8]. The valve element [1] is arranged to prevent leakage through the slit or fissure [8] when a moderate pressure corresponding to the sum of the atmospheric pressure and the static pressure from the product inside the container is exerted on the domed section [1a] of the element but to permit the product to be dispensed from the container when the pressure in the container is increased, the increased pressure acting upon the yieldable domed section [1a] to expand the central slit or fissure [8].
