Abstract: A dispensing device for a bag container a liquid, made of flexible material and forming upper and lower walls through which holes are formed for receiving the device, has a tubular lower part with a top flange which is sealed to the inside of the lower wall and depends through the hole in the lower wall. A tubular upper part has a top flange sealed to the inside of the upper wall and depends through the hole in that wall and is telescoped inside the lower part so as to move up and down in the lower part. The top of the upper part forms a piston such as a collapsible dome extending upwardly through the hole in the upper wall and exposed on the outside of the upper wall and therefore exposed on the outside of the bag. The lower part has a lower end having a self-closing valve and has at least one side port normally open to a space between the flanges and therefore between the bag walls.

Abstract: A flexible-bag self-closing metering dispensing valve for a flexible bag containing a fluid product, has a collapsible dome with an entrance for the product, and a valve seat supported by spokes, below which a diaphragm is positioned with a hole having a periphery seated on the valve seat. The spider and seat and the diaphragm are mounted so they cannot be driven out by sudden depression of the collapsible dome.

Abstract: A self-closing squeeze bottle dispensing valve includes a vent for venting the bottle after squeezing. The valve is made with a cap which can be rotated so as to positively shut-off not only the valve's dispensing orifice, but also its vent, the two shut-offs being simultaneous.

Abstract: A right-angle spray-nozzle for a squeeze bottle is in the form of a one-piece body and utilizes only one velocity-increasing orifice, thereby avoiding the undesirably slow venting associated with a squeeze bottle having a high velocity jet of liquid that intersects with a second high velocity jet of air.

Abstract: What are disclosed are a one pot moisture-curable two-component coating composition comprising a first component having at least one isocyanate group and at least one hydrolyzable alkoxysilane group therein and a second component having at least one oxazolidine group therein, methods of forming a tenacious coating therewith on non-porous substrates such as glass and of further applying a resinous sealant composition over such a tenacious coating used as a primer, and coated substrates having such a tenacious coating thereon without or with a further resinous sealant composition.

Abstract: What are disclosed are a "one pot" moisture-curable two-component coating composition comprising a first component having at least one isocyanate group and at least one hydrolyzable alkoxysilane group therein and a second component having at least one oxazolidine group therein, methods of forming a tenacious coating therewith on non-porous substrates such as glass and of further applying a resinous sealant composition over such a tenacious coating used as a primer, and coated substrates having such a tenacious coating thereon without or with a further resinous sealant composition.

Abstract: Hollow shapes are blow molded with a special form of gate connecting the shapes to the parison from which they are blow molded and permitting subsequent degating of the shapes by ultrasonic mechanical vibration applied to the gates.

Abstract: A molded plastic pill box has a lid hinged by a living hinge at one side of its top so the box can be loaded by a pill manufacturer, the lid when swing closed, permanently locking against reopening. The lid has a pill dispensing opening and a child-resistant closure hinged by a living hinge to the other side of the box top and normally closing the dispensing opening. The box forms a package for the pills and which can be sold by the pill manufacturer to a druggist, an adult purchaser being capable of opening the child-resistant closure for dispensing of the packaged pills. The entire box can be a one-piece molding for minimum cost.

Abstract: A dispensing spray nozzle particularly adapted for application to a squeeze bottle containing a liquid product, comprises two interfitting parts integrally formed as a single plastic injection molding and including an integral hinge on which, after being injection molded with the hinge holding the two parts side-by-side, the parts can be swung together into interfitting relation so as to produce a finished assembly ready for use.
