Abstract: A dispensing closure system for use with an associated container includes a closure assembly having a closure base, and a lid moveably connected to the closure base. The present preferred embodiment of the closure includes a slider element mounted on an upper surface of the closure base for lateral movement between unactuated and actuated positions. The provision of camming surfaces on the slider element, which cooperate with the closure lid, permit convenient, push-button opening of the closure lid to facilitate convenient use by consumers.

Abstract: A dispensing system is provided to dispense a fluent product from a container that has an opening to the container interior. A support base is provided for supporting the container with the container opening oriented at least somewhat downwardly to accommodate gravity flow of the fluent material out of the container through the container opening. The support base has (1) a receiving aperture for receiving the container opening, (2) a discharge aperture, and (3) a flow path extending between the receiving aperture and the discharge aperture.

Abstract: A dispensing valve for dispensing a product from a container. The valve includes a marginal portion, a head portion with a discharge orifice therein, and a resilient, flexible, connector sleeve extending continuously laterally and inwardly from the marginal portion to the head portion. The head portion has an exterior side for interfacing with ambient environment and a peripheral surface. The connector sleeve is connected to the exterior side of the head portion at the peripheral surface of the head portion.

Abstract: A dispensing system is provided for two, constituent, fluent materials which are stored separately and then combined in a dispensing process to form a combination product. The dispensing system includes a container having at least two interior storage chambers, and each chamber has a separate discharge opening. Associated with each discharge opening is a separate, flexible valve. Each valve has an initially closed dispensing orifice which opens in response to a differential between the pressure acting against the side of the closed valve facing toward the associated discharge opening and the pressure acting against the side of the closed valve facing away from the associated discharge opening. In a preferred embodiment, a top is provided downstream of the valve. The top is movable between (1) a close position to occlude a dispensing flow path downstream of the valves, and (2) an open position which permits flow to be discharged from the system.

Abstract: In a dispensing system comprising a container having at least two storage chambers, each for a fluent material, the finishes of the respective chambers are arranged in a contiguous pair defining a cylindrical surface having outer threads, except for two anti-rotational flats. Each finish defines an outlet. A valve of a type that remains closed until opened by a differential between inside pressure and outside pressure overlies the outlet defined by each finish. A fitment defines a mixing chamber having two inlets, one for each storage chamber, and having an outlet. The fitment has two skirts, each having an inner surface having at least one rib, each defining an anti-rotational flat. The fitment fits over the paired finishes and over the valves so that the antirotational flats on the ribs engage the anti-rotational flats on the paired finishes. A collar having inner threads is threaded onto the paired finishes so as to hold the fitment, which holds the valves.

Abstract: A fitment for being sealed to a collapsible pouch has a body having at least one side wall portion, which is provided with spaced steps defining spaced shoulders, an inner end, which faces the interior of the collapsible pouch when the fitment is sealed to the collapsible pouch, and an outer end. The body of the fitment defines a reference plane and a range of peripheral dimensions, each of which is measured around one of the spaced steps or around one of the spaced shoulders, in a plane that is located at one of the inner and outer ends or between the inner and outer ends and that coincides with or is parallel to the reference plane. The peripheral dimensions increase from a smallest dimension at or toward one such end, through intermediate dimensions which between the inner and outer ends do not decrease after increasing, to a largest dimension at or toward the other end.

Abstract: A dispensing system is provided and can be embodied in a dispensing closure for a container having an opening. The system includes a unitary, resiliently flexible, molded valve array structure for being sealingly disposed on the container over the container opening. The valve array structure includes an impervious membrane. The valve array structure also includes a plurality of resiliently flexible, slit valves molded unitary with the membrane. Each valve has a normally closed dispensing orifice which opens when the pressure in the interior of the container exceeds the pressure on the exterior of the valve by a predetermined amount. The valves can be arranged to discharge parallel streams, diverging streams, or converging streams.
