Abstract: A polyolefin mould for casting contact lenses from a polymerizable monomer composition which shrinks on polymerization, said mould comprising: male (50) and female (51) mould halves at least one of which has a flexible diaphragm portion (53, 54) which is shaped to provide a surface corresponding to a lenticular surface, said mould halves (50, 51), when closed together, cooperating to define a mould cavity (52) for receiving a volume of said monomer composition, at least one of said mould halves (50, 51) having a shoulder portion (55, 56) surrounding said cavity and shaped to engage with said other mould half to define an edge moulding portion of said cavity: whereby in use said diaphragm (53, 54) is deflected into said cavity under forces exerted on said mould by said monomer composition when polymerized in said closed cavity (52), thereby compensating for the shrinkage occurring on polymerization and avoiding the formation of bubbles or voids in the resulting lenses.

Abstract: A plastics can 15 has a screw closure comprising a screw cap 34. In the closed position, a flat surface 44 of the screw cap 34 lies in one common horizontal plane with the upper edge of two edge handles 28, 29. When several such cans are stacked one upon another, as the result of the additional support on the flat surface 44, greater stability is achieved. Such cans can, therefore, be stacked with less danger. Of particular importance for cans of more than 10 liter capacity (FIG. 1).

Abstract: The interior of the case is divided by compartmenting walls into a plurality of bottle-receiving compartments and also a central compartment which is not suited for receiving bottles and is elongated. The compartments are hexagonal. At each end of the central compartment there is a Y-intersection of three compartmenting walls. The compartmenting walls are extended upwards at these two intersections at each end of the central compartment and tapered together as they rise. Across the top of the central compartment and attached to the shanks formed by the extensions of the compartmenting wall intersections is a central handle for carrying the case. The handle shanks thus do not require space in the case in addition to the space already taken up by the compartmenting walls, and at the same time provide guide surfaces for the bottles being inserted into the compartments surrounding the end regions of the central compartment. This greatly facilitates machine loading of the case with bottles.

The storage container also includes feet disposed at each corner on the outer surface of the bottom of the container to facilitate mounting containers top to bottom and to securely fasten two containers bottom to bottom. The feet prevent relative lateral movement between two containers.

Abstract: A container for liquids is formed of a shell of resilient plastic which defines a hollow body with at least two spaced posts upstanding from one side, and at least two recesses on the opposite side in which the posts of similar containers may be snugly received. One post has an opening at its upper end for filling the container and emptying liquid from it. The container can be used for the packaging and sale of liquids and, after the container has been emptied of its liquid contents, the containers can be used as toy interlocking building blocks. The stacking of the containers with the posts of containers received in the recesses of adjacent containers in interlocking fashion also facilitates the building of walls or other extensive assemblies of the containers for display purposes and the like.

Abstract: A molded plastic and metal case is provided which is designed to be stackable with other cases of the same construction to provide a sturdy display of the products contained therein and which is also nestable with other like cases to provide compact storage of empty cases. The display case is formed primarily of molded plastic and includes two upstanding metal frames on either side which form handles for carrying the case. Along the inside bottom of the case is a metal ring which is welded to the upstanding metal frames. The upper portion of each handle forms a stacking ledge which is received within a channel positioned adjacent and parallel to the side edges along the underside of each case, thus allowing the cases to be securely stacked. Adjacent each channel is a parallel slot which extends through the underside of each case and is used for nesting empty cases. The slot is designed to receive the frames of the next two lower cases thereby permitting a nesting ratio of 3:1 or greater.

Abstract: A non-skid case for carrying packaged soft drinks and the like. The case has depressions in the lower surface of the bottom panel thereof which extend only partially through the bottom panel. The depressions are configured to entrap a portion of a high friction pad inserted therein to retain the pad, the pad forming a non-skid surface at the bottom of the case. Using this configuration, cases for carrying soft drinks may be molded in one piece using polyethylene and used on conveyor systems, etc. in place of wooden cases without sliding tendencies which are otherwise caused by the self-lubricating characteristics of polyethylene. Alignment of the pads in accordance with the ordered disposition of bottles in the case further enhances the stability of filled and stacked cases, with the lack of a through-hole in the region of the pad avoiding the local entrapment of syrups, etc., thereby avoiding any organic growth in that region.

Abstract: A top insertion, tray stacking wire with coplanar feet extending outwardly in opposite directions at the bottom of the wire with a prong extending laterally outward from the end of each foot at a substantial angle to the plane of the feet. The wire is held in a horizontal disposition for insertion of the feet and attached prongs into a slot aperture in the top edge of a corrugated paperboard tray and the like having a double wall construction. The wire includes a U-shaped body attached to the divergent feet wherein the legs thereof resiliently separate from one another to abut the ends of the slot aperture with the divergent wire feet projecting underneath the ends of the aperture. While the U-shaped body is being pivoted to assume a vertical orientation, the prongs bite into the corrugations of the adjacent wall, simultaneously pressing the pivoting feet into firm engagement against the wall adjacent thereto whereby the stacking wire is maintained in a firm, upright disposition.

Each vertical section extends vertically along one side of the vacuum cleaner and through a respective handle on the upper container and engages a respective handle on the lower container. A hook is formed in the lower end of each vertical section for extending around and underneath the respective lower handles for engaging the same. The horizontal sections extend from the upper end of the vertical section over the top of the upper container to a point where they meet. At this point the ends of the horizontal sections turn upward and abut against each other.

The bottom portion is provided with supporting and stacking nubs that are situated at positions corresponding to the projecting top wall portions, and the top wall portions have nub-receiving stacking recesses positioned on opposite sides of the handle so as to enable stacking of a like container on the container by engagement of supporting and stacking nubs of the like container in the stacking recesses of the container.

Abstract: Viable cells of an avirulent self-clearing strain of B. bronchiseptica are administered as an intra-respiratory vaccine. An aqueous suspension of the cells is applied to the respiratory mucosa immediately after incorporating a non-inhibitory amount of a wetting agent promoting the mucosal implantation of the cells. Effective immunization can thereby be obtained against diseases such as kennel cough in dogs and atrophic rhinitis in swine even through the strain of B. bronchiseptica is so highly attenuated that it is self-clearing from the respiratory mucosa.
