Each of the pumps has an inlet for receiving liquid from the associated chamber. A surface applicator is mounted on the housing to apply the two-component solution to a surface, such as a user's skin. A manifold is connected to the outlets of the pumps to mix the liquids from the pump outlets and direct the mixed liquids to the applicator. One of the housing and the applicator has a portion that is moveable with respect to the pumps for activating the pumps and delivering liquids from the chambers simultaneously to the applicator.

Abstract: The invention is a trigger sprayer comprising a tubular nozzle bushing and a nozzle cap rotatable on the bushing. The nozzle cap has an end wall with a first swirl chamber formed on the rear face thereof offset from the axis. Passages to a second chamber are diametrically opposite the first chamber. Both chambers have orifices directed out the front of the cap. The first orifices is surrounded by a foaming sleeve. The second orifice is positioned forward of the first orifice so that the spray cone emanating from the second orifice does not hit the foaming sleeve. The cap can be rotated to connect liquid from the delivery tube to the swirl chamber for one or the other orifices.

Abstract: The invention relates to a hand lever-operated spray pump (3), particularly for attaching to bottles (2) or similar, having a pump plunger (6) which moves linear in a pump chamber (7) on the housing side and which is connected with the hand lever (5) at the rear of a mouth piece opening (9) and which returns to its starting position as a result of a spring loading, and proposes, for the purpose of achieving a structurally simple, functionally reliable solution, to allocate two hinge points (I, II) to the hand lever (5) one of which (I) is movable in a linear guide on the housing side and the other (II) is arranged on the housing on the side opposite to the mouthpiece (9). In such a way that both hinge points (I, II) are connected by means of two buckling bridge sections (a, b).

Abstract: A toggle-action dispensing closure includes a base having an upper edge, and internal thread or bead for securement to a container, and a recessed deck disposed beneath the upper edge and having a fluid dispensing opening. A dispensing disk or actuator is pivotally mounted to the base above the deck, and includes a seal for cooperating with the dispensing opening for selectively opening and closing the dispensing opening. A lug element on a periphery of the disk has a sharp edge in opposed abutment with the upper edge of the base to resist first movement of the actuator to open the dispensing opening. First movement of the actuator to open the dispensing opening causes permanent deformation at the upper edge of the base and/or at the lower edge of the element, such that the element and the edge present lesser resistance to opening of the actuator after such first opening.

Abstract: This pump body is mounted on a container and has a forward manually operated pump and a rearward vertical container fill conduit. In the filling process, the container is filled through the conduit, and a closure is then applied to the top of the conduit. The closure may be part of the pump body housing. Multiple containers with their pump bodies may be filled simultaneously.

Abstract: A package for tablet products that includes a container having an interior volume for holding the tablet products and a closure secured to a cylindrical finish of the container. A product hold-down device has an axially resilient central portion, a lower portion for engaging the upper surface of the product within the container, and an upper portion for securement within the container finish to hold the device in place within the finish, with the closure removed from the finish, against the axially resilient forces applied to the device by engagement of the lower portion with product in the container and resilient compression of the central portion of the device. Thus, the hold-down device can be inserted into the container and secured to the container using automatic packaging equipment, and the container closure then applied to the container. In use, the closure is removed from the container, and the device is removed and discarded by the user.

Abstract: A plastic closure that includes a cap having a base with a peripheral skirt defining a cap interior and threads on the skirt for securing the closure to a container. A liner is secured to the interior of the cap, preferably by compression molding in situ. The liner consists essentially of a blend of a matrix polymer, a particulate barrier polymer and an compatibilizer. The heat and pressure of compression forms the particles of barrier polymer into platelets that are oriented essentially parallel to the plane of the disk.

Abstract: A closure and container package that includes a container having a finish with an external thread, and a closure having a base wall and a peripheral skirt with an internal thread for threadably engaging the external thread on the container finish. An internal rib on the skirt extends axially of the skirt between overlapping reaches of the internal thread for frictional engagement with the external thread on the container finish to retard rotation of the closure onto and off of the finish. In the preferred embodiments of the invention, there are diametrically opposed ribs on the internal surface of the peripheral skirt extending between overlapping reaches of the internal thread, with the ribs being of lesser radial thickness than the internal threads. A tamper-indicating band is coupled to the lower edge of the peripheral skirt by frangible bridges for engagement with a bead on the container finish.

Abstract: A tamper-indicating closure of integrally molded plastic construction that includes a base wall having a peripheral skirt with internal threads for engaging external threads on a container finish. A tamper-indicating band is connected to the edge of the skirt by a plurality of circumferentially spaced integral frangible bridges. A stop flange extends axially outwardly and radially inwardly from an edge of the band remote from the skirt for inversion and engagement with a bead on the container finish. The stop flange is in the form of a circumferentially continuous base of uniform thickness circumferentially of the band, and either uniform or increasing thickness radially and axially of the band. A plurality of circumferentially spaced lugs are integral with and extend from the base. The lugs widen uniformly from zero thickness at the band to a maximum thickness at the free edge of the flange.

Abstract: The selector wheel is mounted to rotate about the axis of the nozzle cap, and a spray window and foaming sleeve are formed in the wheel offset from the axis. The window or sleeve is registrable with the offset spray orifice by rotating the wheel. Either window or sleeve can be brought into registry so that the discharge is spray or foam.

Abstract: A plastic closure that comprises a cap having a base with a peripheral skirt defining the cap interior and threads on the skirt for securing the closure to a container. A liner is secured to the interior of the cap, preferably by being compression molded in situ on the base. The liner consists essentially of a multiplicity of alternating layers of a matrix polymer material such as EVA and a barrier material such as EVOH to resist transmission of gas, water vapor and/or flavorants through the liner. The matrix polymer material preferably is preblended with a compatibilizer material such as a maleic anhydride grafted polymer that ties the matrix polymer material to the barrier material.

Abstract: This articulated trigger/cover unit for a pump dispenser is formed with retainers on proximate relatively moveable walls to hold parts in stable configuration for handling by automatic assembly equipment.

Abstract: A pill dispensing package that includes a circular base having a pill dispensing opening adjacent to its periphery. A circular package disk has a peripheral array of frangible elements containing pills to be dispensed disposed for selective alignment with the base dispensing opening, and indicia for indicating dosage periodicity. A circular cover overlies the package disk, and is moveably secured to the base. The cover has a window for observing the periodicity indicia on the package disk, and a button for manual urging against the package disk to dispense a pill through the base opening from the frangible element aligned with the opening. The cover is resiliently urged axially away from the base and circumferentially with respect to the base, and is constructed to permit limited axial and circumferential movement with respect to the base.

Abstract: This pump dispenser has a downward tubular support providing a lead-in for a resilient closure. The closure is formed with an upwardly facing inward lead-in chamfer and spaced deep arcuate recesses in the top surface so that the wall between the recesses and the inner diameter is outwardly resilient to permit an attachment flange to stretch the wall outward and permit snap passage of the attachment flange. In this manner the closure is permanently attached to the pump body without the need for welding or separate attaching parts.
