Abstract: A method for manufacturing a hardened casing for a vane pump is disclosed. The method includes providing a vane pump casing; hardening the casing by (i) cleaning the casing with a high pressure fluid containing abrasive material, (ii) loading the casing in a furnace, (iii) purging the furnace with an inert gas followed by purging the furnace with ammonia, (iv) conducting a first heating of the casing in the furnace at a first temperature of about 1200° F. for a time period of about 4 hours, (v) conducting a second heating of the casing in the furnace at a second temperature of about 1000° F. for a time period of about 4 hours, and (vi) cooling the casing and purging the furnace with an inert gas before removing the casing.

Abstract: An integrally formed closure for a container is provided. The closure includes a base with a plurality of dispensing apertures and a cover coupled to the base for movement between a closed position and an open position to allow dispensing of matter from the container. The base includes a top portion having a first contour and the cover has a second contour configured to substantially correspond to the first contour.

Abstract: A closure for a container is disclosed having a base with at least one dispensing aperture and a cover coupled to the base for movement between a closed position and an open position to allow dispensing of matter from the container. The base includes a top portion having a first contour and the cover has a second contour. The second contour may be configured to substantially correspond to the first contour. A closure for a container is also disclosed having a base that includes a topside having a contour. A cover is coupled to the base and includes an underside configured to substantially correspond to the contour and a rib extending downwardly from the underside to move matter accumulated on the topside of the base into the container when the cover is moved toward the closed position.

Abstract: A container having a receptacle and a cover is disclosed. The receptacle includes a generally rectangular base portion, a continuous sidewall portion, and a collar. The sidewall portion includes a lower end and an upper end. The lower end of the sidewall portion is coupled to the base portion and the upper end defines an opening. The collar extends around the sidewall portion proximate the upper end. The cover is coupled to the receptacle and includes a top portion, a skirt, a flap, and a tear strip. The skirt extends downwardly from the periphery of the top portion. The flap is hingably coupled to the top portion proximate a corner of the closure and is moveable between an open position in which access is provided to the opening in the receptacle and a closed position in which the opening in the receptacle is closed. The flap includes a closing apparatus to releasably retain the flap in the closed position. The tear strip is removable and is coupled to the flap and the skirt.

Abstract: A closure for a container includes a base having a first end configured for mounting on a container and a second end enclosed by a top portion. The container includes a first projection extending from an outside wall. The top portion includes a platform having at least one opening for dispensing material from the container. At least one flap is coupled to the top portion and movable between an open position for dispensing the material and a closed position for covering the opening. A second projection extends from an inside wall of the base toward the top portion and is configured to coact with the first projection on the outside of the container, so that the closure is configured to resist separation from the container once the closure has been attached to the container.
