Abstract: A filter housing assembly includes a base plate, an adapter block, and a shroud. The base plate may be permanently installed in a fluid-conveying system of conduits. A filter member is secured to a filter-receiving formation such as a pipe nipple extending from the adapter block and the shroud is secured to the adapter block to cover and seal the filter member. The adapter block is releasably secured to the base plate. The arrangement facilitates insertion and removal of the filter housing assembly into and out of the fluid-conveying system of conduits by converting multiple junction points into a single junction point, at which a subassembly consisting of just the shroud and the adapter block are connected into the system.

Abstract: A tamper-evident label suitable for placement onto a container and cap assembly. The label may be characterized as a planar sheet having a tear strip that divides upper and lower panels. The lower panel of the label attaches to the container, while the upper panel, defined by at least one tab, and preferably two tabs, is attached to the cap. To open the container and cap assembly, the tear strip is pulled across the label to separate the two panels of the label. Thereafter, the cap may be removed from the container to reveal the contents of the container.

Abstract: The invention relates to an assembly for preparing and dispensing a solution and to the stopper for such an assembly, said assembly comprising a first bottle containing a first liquid component, with an elongated head; a second bottle containing a second component, liquid or solid; a stopper for this second bottle presenting a recess whose shape is homologous of the head of the first bottle, and in which said head is for example screwed. The bottom of the recess is constituted by a membrane of deformable material comprising an axial orifice which is hermetically closed, in the absence of deformation of the membrane, by the natural radial constriction of the material of the membrane. By screwing the first bottle in the stopper, the membrane is axially deformed and the orifice is radially distended, thus allowing the two bottles to be placed in communication in reversible manner. The invention also relates to a process for making the stopper.
