Abstract: A container and method for preventing leakage therefrom through isolating deformation in the container caused by external forces. The container comprises a container wall having an opening therein, the opening capable of receiving a closure bushing with a sealing member wedged between the closure bushing and the container wall, and a weakened portion of the container wall not in wedged engagement with the sealing member capable of bending in response to an external force so as not to deform the portion of the container wall in wedged engagement with the sealing member.

Abstract: A childproof lock for a reciprocating fluid dispensing pump of the type that is threaded into a locked position. In one set of embodiments, the lock requires simultaneous displacement in a direction other than unthreading to permit reciprocation of the pump. In another set of embodiments, fluid flow is permitted only when a lock is simultaneously displaced in a direction other than reciprocation of the pump.

Abstract: A gasket singulation apparatus for separating one gasket from a web-connected stack of gaskets includes a mandrel for receiving the web-connected stack and an arrangement of cylinders which are used to support the web-connected stack of gaskets and to pull one gasket away from the remainder of the web-connected stack so as to singulate that one gasket. A first plurality of cylinders are used to support the web-connected stack. A second plurality of cylinders are used to pierce any connecting material between the gasket to be singulated and the remainder of the stack. Once the web material is pierced, cylinder movement is effected so as to pull the selected gasket away from the stack, allowing any connecting material to sever and thereby singulate one gasket from the stack. Once the gasket is singulated, various insertion mechanisms are disclosed for inserting the singulated gasket into a pail lid groove.

Abstract: A fluid dispensing system includes a closure assembly. The closure assembly is configured to enclose a container opening. The closure assembly has a fluid supply tube with an opening and a shut-off valve threadedly coupled to the supply tube. The shut-off valve has a valve member configured to close the opening in the supply tube upon rotating the shut-off valve in a first direction and to open the opening in the supply tube upon rotating the shut-off valve in a second direction. A cap assembly is coupled to the closure assembly. The cap assembly has a connector member with a fluid passage fluidly coupled to the supply tube. The cap assembly is coupled to the shut-off valve to rotate the shut-off valve in the first direction and the second direction. The configuration of the system eliminates the need for spring based valves.

Abstract: A blow-molded, plastic paint container for storing and dispensing paint includes a blow-molded container body defining an externally-threaded neck portion, an injection molded plastic closing cap, internally-threaded so as to be threadedly securable to the neck portion for closing the container body, a liner assembled into the closing cap and a depending annular wall positioned between the neck portion and the liner in order to cause any paint skin that forms to be formed into two portions, one portion being adjacent to the liner and the other portion being adjacent to the container body. Each paint skin portion adhering to its corresponding structural portion of the paint container and remaining intact. In a related embodiment, the annular wall is replaced with three cutting blades.

Abstract: A container for storage and dispensing of paint includes a unitary, molded plastic container body defining an interior volume and including an annular neck portion which is externally threaded and which defines the container opening through which the contents are dispensed. Included as part of the paint container is a dispensing spout which is positioned within the annular neck portion and includes a pouring lip, a wiping edge, and a paint brush receptacle with a plurality of drain-back apertures. The dispensing spout includes two threaded portions, one which engages the neck portion and the other which receives a removable closing cap. The cap is constructed and arranged to close the container opening. A transporting handle is provided and is attached directly to the dispensing spout such that the cap, spout, and handle can be provided as a subassembly for threaded engagement onto the container body.

Abstract: An airless dispenser pump assembly includes a pump mechanism with an inlet valve that is configured to efficiently pump viscous fluids and that is able to be pre-primed when the pump mechanism is attached to a container. In one form, the inlet valve includes a seal member that seals an inlet port of the pump and an outer support member that secures the inlet valve to the rest of the pump mechanism. Two or more legs generally extend in a circumferential direction between the support member and the seal member in order to create a large flow opening for fluid flow through the inlet valve when opened and to rapidly close the inlet valve. The pump mechanism further includes an outlet valve that is configured to draw fluid back from a nozzle of the pump after dispensing in order to minimize build up around the nozzle.

Abstract: A container for the storage and dispensing of a liquid and which incorporates a sealing mechanism includes a blow-molded container body including a neck portion having a series of external threads and defining an annular, non-planar sealing surface, a pouring spout assembled into the body and a unitary closing lid including a series of internal threads constructed and arranged to engage the threads of the neck portion. The unitary closing lid includes the sealing mechanism in the form of a pair of annular sealing lips constructed and arranged to be compressed against the annular, non-planar sealing surface to establish a sealed interface between the closing lid and the body.

Abstract: A container closure assembly for closing the neck opening of a container includes a closure plug for threaded engagement with the neck opening, a sealing gasket positioned between the container and the closure plug, and a unitary, molded plastic overcap constructed and arranged for assembly to the closure plug. The overcap includes a top portion defining a pair of weakened score lines that partition the top portion into three sections. A surrounding sidewall connects a pair of flange sections to first and second outer sections of the top portion. A center post axially extends from the center section and includes external threads for engagement with internal threads on the closure plug. The overcap includes a raised portion in unitary construction with the top portion and spanning the pair of weakened score lines so as to visually reveal stress discoloration upon upward movement of the first and second outer sections.

Abstract: A vented closure for closing and venting a container with threaded engagement to a neck portion of the container for dispensing fluid from the container includes a unitary, molded plastic cap constructed and arranged for threaded engagement to the container. The threaded cap defines a septum orifice that is sized and arranged to receive a siphon tube. A gasket is assembled into the threaded cap for sealing the interfit between the vented closure and the container. An elastomeric venting valve is assembled into the threaded cap and the venting valve includes a septum with a slit therein for receiving in a self-sealing manner the siphon tube. A retainer ring is used to capture the venting valve within the threaded cap and a safety ring in unitary combination with the threaded cap retains the vented closure on the container.
