Abstract: A toggle-action dispensing closure for a container is provided for manipulation between a closed, non-dispensing orientation and an open, dispensing orientation. The closure includes an actuator pivotally mounted along a tilting axis on a body secured to the container. The actuator is tiltable by applying force to the actuator on one side of the tilting axis so as to move the actuator from a non-dispensing position to a dispensing position. The actuator includes a flange having an engagable surface. The closure body includes an annular wall in which the actuator is received, and the annular wall includes an inwardly projecting interference member which underlies the actuator engagable surface and prevents tilting of the actuator unless a sufficient predetermined, initial opening force is exerted on the actuator to cause permanent, plastic deformation of the engagable surface and/or interference member.

Abstract: A valve system is provided with a wall portion that includes an inlet side, an outlet side, at least one aperture extending between the inlet and outlet sides, and a valve seat on the outlet side. One preferred form of the valve system also includes a movable valve member having a spout, a mounting portion, a toggle portion, and at least one seal surface for sealingly engaging the wall portion valve seat when the valve member is toggled to a closed position to prevent flow from the wall portion aperture through the spout.

Abstract: A dispensing closure that has a cover which is provided with a scrubbing structure that includes protuberances. In a preferred embodiment, the scrubbing structure is a resilient flexible material which has been molded on a generally rigid base. The base is injection molded in an initial injection molding step from a first material, and the scrubbing structure is injection molded in situ in a subsequent molding step from a second material onto said first material to become bonded thereto.

Abstract: An improved dispensing closure system for dispensing a product from a container includes an elongate or oblong dispensing orifice for dispensing a ribbon of product. One form of the dispensing closure system also includes a spout having a dispensing orifice that is oriented at an angle relative to the closure deck and relative to the flow direction of product from the orifice. The closure provides for the dispensing of product in a clean and controlled manner without mess. One form of the closure system also incorporates conical geometries in transition surfaces extending from the container opening to the dispensing orifice. The conical geometries of the transition surfaces provides for a smooth transition of product flow from the container opening to the dispensing orifice, while minimizing the volume defined by the closure system spout and thereby providing increased “suck-back” and an abrupt “cut-off” of product compared to prior art devices.

Abstract: A closure structure for a container includes a cap and a surrounding tamper-evident sleeve. The tamper-evident sleeve is initially engageable with a retaining element of the container located below the cap to prevent axial upward displacement of the sleeve with respect to the container. The sleeve includes a retention member overlying the cap to prevent manipulation of the cap to an open condition. The sleeve includes a frangible feature arranged to be torn to facilitate removal of the sleeve to permit manipulation of the cap to an open condition.

Abstract: A tamper-evident dispensing closure system is provided for a container. The system has a body for extending from the container at the container opening. The body defines a dispensing orifice, a channel, and a retention member projecting over a portion of the channel. The system includes a lid for being moved between a closed position and an open position. An anchor member is provided for being received in the channel and has an engaging portion for engaging the retention member when the anchor member is received in the channel. At least one frangible web initially connects the anchor member with the lid so that the frangible web breaks when the lid is initially lifted from the closed position.

Abstract: A closure structure includes a closure body having a deck and depending sidewall, and a dispensing orifice through said deck. A closure cap has a lid part attached by a hinge to the body, and a cover part frangibly connected to the lid part, on a side of the lid part opposite the hinge. The lid part is latched to the body at lateral positions located between the hinge and the cover part. The cover part covers a lifting lip extending from the lid part. Removal of the cover part exposes the lifting lip for lifting by the user to open the lid part from the closure body.

Abstract: A dispensing valve is mounted in a dispensing aperture of a closure that has (1) a deck around the aperture, and (2) a hinged lid for closing over the aperture. The valve includes a marginal portion, a head portion with a discharge orifice therein, and a resilient, connector sleeve extending between the marginal portion to the head portion. The connector sleeve has a generally U-shaped cross-section that defines a first leg that is connected with the marginal portion and a shorter second leg connected with the head portion. The connector sleeve locates the head portion below the closed lid. An arcuate junction portion of the connector sleeve joins the first and second legs. The arcuate junction portion projects from the deck aperture when the lid is open. When the lid is closed, the arcuate junction portion is engaged and elastically deformed by the lid, and that prevents the valve orifice from opening.

Abstract: A molded article is produced by a method of compression molding employing a specially shaped billet of thermoplastic material which is positioned at a predetermined location in a predetermined orientation with respect to the mold cavity surfaces of a mold part. In a preferred embodiment, the billet has a generally egg shape and is located adjacent a mold surface defining a small mold cavity region between two larger cavity regions.

Abstract: A tamper-evident structure for use in a resealable dispensing closure system includes a lid and a flexible, frangible tamper-evident member extending from the lid to a drop ring. The drop ring is adapted to engage a bottom end of a closure body in the closure system. Preferably, the lid, frangible tamper-evident member, and drop ring are provided as a unitary, integrally molded structure. In a preferred embodiment, the closure body can also be molded as a unitary part of the structure. The lid, frangible tamper-evident member and drop ring are assembled on the closure body by first installing the lid in a closed position on the closure body. The drop ring is then pivoted downward relative to the lid, thereby causing the frangible tamper-evident member to become disposed adjacent the closure body skirt. The drop ring is located at the bottom of the closure body. The system can then be installed on a container so that the drop ring locks under a bead or lip on the container.

Abstract: A fluid dispenser is provided with a fluid containment unit and a support unit. The fluid containment unit includes a bulb, a nipple, and a tether connecting the bulb to the nipple. The support unit includes a face plate, a retaining ring, and a releasable latch for securing the face plate and retainer ring together to clamp between them the fluid containment unit when the fluid containment unit is in a folded configuration locating the bulb and nipple in communication with each other.

Abstract: A dispensing valve is provided for being sealingly disposed with respect to, and dispensing a product from, a discharge opening of a container. The preferred form of the valve includes a generally annular marginal portion adapted to be sealingly engaged when the valve is sealingly disposed with respect to the container discharge opening. The valve also includes a central head portion extending from the marginal portion. The head portion has an exterior side with a generally concave shape when viewed from outside the container and has an interior side with (1) a planar central area, and (2) a generally curved, radially outer portion which tapers toward the exterior side such that the periphery of the head portion is preferably thinner than the center of the head portion. The head portion includes at least one normally closed orifice that is defined by at least one slit that extends transversely through the head portion from the exterior side to the interior side to define flaps.

Abstract: A spray dispensing closure includes a spray plug and a cap cooperating therewith to selectively occlude passages in the spray plug. In one embodiment, a spray plug includes a set of inner passages for conveying product from a dip tube through the spray plug and a set of outer passages for conveying air from a head space in the container. The inner passages communicate with an inner flow space and the outer passages communicate with an outer flow space. A cap cooperates with the spray plug to define an outer chamber and an inner chamber which are isolated from one another when the cap is in the closed position, thereby preventing the mixing of air and product. As the cap is moved to the open position, the cap chambers are permitted to communicate with one another and, as the container is squeezed, a product/air mixture is formed in the closure. A central spray plug post has an upper portion that forms at least one restrictive passage with an inner wall of the cap when the cap is in the open position.
