Abstract: An actuator tip diffuser may be retrofitted onto existing pump dispensers to create a scatter flow. The scatter flow can be induced by using patterns with larger area sections produce separate, individual streams. Increasing the length of the orifice adapter and adding a center outer ring also reduced spatter. In all instances, the actuator tip diffuser includes a through-channel, with an inlet fitted to the existing actuator nozzle on one end and a downwardly disposed outlet for discharging fluid via the pattern of orifices/structure noted above. The tip may also include one or more retainer tabs to create a snap fitting to existing dispenser pumps.

Abstract: A surgical preparation applicator device has a pre-loaded container of surgical preparation liquid, the container having a front closure at its front end. The container is received in an applicator body which includes a tubular receiving structure, movable from an initial position to an open position whereby a cutter of the applicator body opens the front closure to allow liquid to flow forwardly to an applicator pad. The applicator body defines a flow path between the container and the applicator pad. The container has separate chambers containing different component liquids of the surgical preparation liquid. The chambers are separated by an internal wall and being side-by-side, each having a front opening at the front end of the container with the front closure closing off both front openings.

Abstract: An injection molded plastic closure, stackable with similar closures in a known manner to prevent warping during cooling and to increase box storage capacity, is formed with a lead-in taper at the bottom of the closure skirt, maintaining and enhancing the stacking function while greatly reducing and nearly eliminating problems of cross-threading when the closure is screwed onto a container by machinery during a capping operation.

Abstract: A dosing device for dispensing liquid from a container (1) in which flow through flow openings (23) to an outlet tube (44) is blocked after controlled delay by an obturator (3) moveable within a control chamber (2) mounted in a container neck (101) behind the outlet tube (44). Movement of the obturator (3) is governed by restricted flow through control openings (28) at the rear of the control chamber. Restoration of the obturator to the back of the control chamber facilitates repeated dosing. An elastomeric element (6) of resiliently deformable material promotes a seal to achieve a cleanly defined dose. In one proposal the elastomeric element coats the surface of the obturator and/or the outlet tube (64) to cut off the flow. Another proposal provides a one-way elastomeric valve element (63) for blocking the flow openings to enable rapid recovery after a dosing operation.

The funnel includes an inlet portion for receiving the flowable product, an inserting end portion for insertion into the capless fitment and a body portion having a tapered hollow interior and extending between the inlet portion and the inserting end portion. The inserting end portion includes a skirt which is constructed and arranged for proper engagement with the normally-closed capless fitment so as to open that capless fitment and allow the flowable product to be dispensed into the receptacle.

Abstract: The invention relates to dispensers for fluid products, particularly oral dosing of medicines. The dispenser is a pump dispenser and has a separate nozzle attachment. The nozzle and dispenser may be uncoupled in a holding position or coupled position. A child resistance feature is disclosed which prevents unauthorized coupling of the dispenser and nozzle, thereby preventing unauthorized dispensing of product. The child resistance feature only allows coupling of the dispenser and nozzle when a coupling control element is triggered and then maintains this coupling with additional features. A protective cover for the dispenser is also disclosed, which covers the nozzle attachment and pump plunger button.

Abstract: The present invention relates to an adaptation device arranged to transform a pump not specific to the production of foam into a foam pump. The device comprises a supply conduit extending from the inlet of the pump as far as an elbow below the level of foaming liquid and rising above the level of the liquid to terminate in air added to the structure of a pump for fluids. The supply conduit comprises a suction hole enabling suction of liquid when air circulates before the hole. A filtering grate is added to a discharge conduit and connected to the pumping outlet. The foaming liquid comprises, in part, water to produce foam without additional water.

Abstract: Pump dispenser, particularly a movable-nozzle pump dispenser, is intended especially for use in dispensing oral medicines e.g. to children. One feature disclosed is a tooth or ratchet structure engageable between the plunger head and the pump cylinder body. This enables optional holding of the plunger at an intermediate position during a dispensing stroke, so that a dose can be given bit by bit. Other proposals are formations around the top of the cylinder body which interact with the inside of the plunger to control or limit movement of the plunger according to their relative rotational orientation. For example the plunger may be locked up unless turned forcibly past a rotational stop. A related feature is a spring lock tab preventing rotation of the plunger unless the tab is pressed to release it. The product container may contain balls to cause agitation.

Abstract: A pump dispenser includes a container whose top opening is closed off by a base structure of a pump module. The structure is shaped to guide air to an air pocket region adjacent the wall. This air pocket region communicates with the pump inlet opening so that air can be discharged. The pump may include a pump body and a plunger which incorporate respective different ones of a click projection and a click actuating formation, constituting a click indicator.

Abstract: Applicators are described suitable for the application of liquid to patient's skin. An applicator pad (3) is supported on a support flange (23) of an applicator housing (2), which receives a liquid cartridge (5). To moderate the rush of liquid on to the back of the applicator pad a flow distributor plate (6) is positioned on the rear position of the pad (3), restricting flow onto the pad to an annular slit opening around the plate (6). The front surface of the plate (6), opposing the pad (3), may have one or more grooves so that liquid can flow from the edge towards the center. Also disclosed, as an alternative, is the use of a projecting cantilevered tongue structure to distribute liquid across the rear surface of the sponge pad. The pad may have a hooked lobe shape for a front end of the applicator pad.

Abstract: A pump dispenser is intended for oral administration of medicines. A pump receives fluid product through a valved inlet from a container, preferably of the airless type with a follower piston. The dispenser may be a movable-nozzle or fixed-nozzle dispenser. The discharge outlet of the dispenser has a stub nozzle incorporating a closure valve. A spring urges the closure valve forward to close a discharge opening of the stub nozzle. The nozzle attachment is shaped for oral dosing and has an internal rearwardly-projecting actuating structure which, when the nozzle attachment is coupled onto the stub nozzle, pushes the closure valve open. When the nozzle attachment is removed the spring closes the outlet again. Child-resistant features are described for fitting the nozzle attachment to the stub nozzle.

Abstract: A pump dispenser for dispensing a liquid product from a container includes an inlet valving arrangement, a plunger and piston arrangement, an outlet valving arrangement and a dispensing nozzle. The dispensing nozzle is a snap-together combination of a unitary, molded plastic nozzle body and a unitary, molded plastic outlet member. The nozzle body defines an exit passageway for the liquid product being dispensed from the container. The outlet member includes an outlet opening and a weir which is positioned between the outlet opening and the exit passageway. Use of the weir affects the exit velocity of the product being dispensed and also provides a barrier so as to prevent remainder or residual product from seeping into or around the outlet opening where it might coagulate.

Abstract: A dispenser pump is disclosed of the moveable-nozzle type, arranged for sealing a vent path in the extended position of the pump plunger. A pump body includes an internal collar formed at the lower end of a tubular insert, through which the vent path passes. This collar has a seal portion. The plunger has a complementary seal portion which makes a guided and fitting engagement with the collar seal portion. One or both of the plunger seal portion and the collar seal portion is formed as an annular taper, so that the seal portions are guided into close engagement with one another. Plunger lock-down formations are constructed to engage at the bottom of the body insert and remain below the top opening of the body.

Abstract: A closure assembly for a container including an internally-threaded annular flange, an externally-threaded closure plug that is received by the annular flange, and an annular gasket positioned between the annular flange and the closure plug for establishing a sealed interface. The container includes a container end panel that is formed over and around a portion of the annular flange and provides an inner axial wall that is positioned between the annular flange and the annular gasket. The clearance between the closing plug and the inner axial wall relative to the size of the annular gasket determines the degree of radial compression of the annular gasket as the plug is threaded into the flange. A radial lip of the plug is designed to contact an upper surface of the container end panel that is formed over the flange as a visual indication when the required tightening torque of the plug within the flange has been reached.

Abstract: A pump dispenser in which the associated container interior reduces its volume progressively as product is dispensed to avoid air contact with the product. An air trap member having a downwardly-convex dish form is provided below a floor of the associated dispenser module around an inlet to guide any such air away from the inlet. A peripheral portion forms a retaining lip for flexible wiping contact with the container wall interior, allowing air passage on assembly of the dispenser. A central tubular formation of the trap member separates the trapped air from the inlet and can be used to plug the trap member into the inlet.
