Abstract: An airless squeeze bottle sprayer comprised of a tube retainer, an orifice cup and a closure. The tube retainer has a product outlet port, a post, and at least one tangential apertures through which fluid is expelled from within the container. The orifice cup has an annular mixing or turbulence chamber wherein the fluid from within the container is mixed up before being expelled out of the orifice cup through a discharge orifice. A dip tube depends from the tube retainer and defines a path for the fluid from the bottom of the container to the annular mixing chamber. When the container is squeezed, fluid is forced up through the dip tube into the mixing chamber and out of the container through the discharge orifice in the orifice cup. Any air that is introduced into the container and expelled out of the container is done so through the same path as the fluid, the sprayer lacks any distinct or separate air ports.

Abstract: An aspiration-type sprayer assembly adapted for being coupled to both the end of the hose and to a chemical container has a housing including a carrier liquid inlet passage, a chemical liquid inlet passage and a discharge passage. The cylindrical rotatable valve within the housing has a carrier liquid duct and a chemical liquid duct opening into the carrier duct for interconnecting the inlet passage in a first rotative position of the valve, and the valve is capable of closing the inlet passages in a second rotative position of the valve. The rotatable nozzle versus the discharge in selective directions, and the assembly is capable of being manipulated by the provision of a handle grip. An anti-siphon assembly is provided at the coupling between the sprayer housing and the water hose end to avoid pressure and back flow from the sprayer. And chemical/water mix can be exchanged substituting the various tube retainers having different size inlet ports.

Abstract: An actuation device capable of adapting a conventional pump dispenser into a lever or trigger sprayer, the actuation device having a housing comprised of a first part that is removably connected to a second part and when the two parts are connected, a pump dispenser is received within the housing. The first part of the housing has an opening adjacent the nozzle of the pump dispenser that allows the contents of the pump dispenser to be sprayed out through the opening. A lever is hingedly mounted to the housing via a plurality of trunnions and associated trunnion cradles and has a leg portion that makes holding and squeezing the lever easy and comfortable. The lever also has at least one arm disposed adjacent an annular rim of the skirt of the pump dispenser so that when the lever is moved, the arm of the lever presses against the annular rim and causes the pump dispenser to actuate and spray fluid from the pump dispenser to the target.

Abstract: A fluid pump dispenser of the loss motion piston type provides for maintaining the discharge open a slight interval at the commencement of each plunger upstroke while the pump chamber expands to retract product from the discharge passage into the chamber to thereby avoid the formation of product droplets at the exit end of the discharge. Such is effected in accordance with one embodiment by reducing the friction force acting between the piston and the pump cylinder relative to the friction force acting between the piston and the stem. In another embodiment an inlet valve assembly has a portion lying in the path of the piston which portion is connected by spring legs to a valve portion such that the restoring force of the spring legs shifts the piston together with the stem at the commencement of the plunger upstroke which maintains the discharge passage in open communication with the chamber.

Abstract: A trigger actuated sprayer has its shroud provided with laterally extending side saddles having undersurfaces defining supports extending longitudinally and continuously between forward and rearward ends of the shroud to provide for ergonomic supports of the sprayer on the top of the hand of the operator when the sprayer is grasped during use. The lateral outward extent of the side saddles is minimized by the provision of a constricted throat portion of the shroud located beneath side saddles.

Abstract: An open-fronted shroud covers a pump body of a trigger actuated pump sprayer and comprises a one-piece cover of at least one molded thermoplastic material having an upper section and a lower section, the cover having a rearwardly extending portion defining a saddle for supporting the pump sprayer on top of the operators hand during use. The upper and lower sections are interconnected by an integral hinge at a terminal end of the rearwardly extending portion for pivotal movement between an open position of the sections during molding and a closed position when mounted on the pump body during use.

Abstract: A self-resetting child-resistant trigger sprayer having a lock slidingly mounted on the trigger lever for locking the trigger sprayer. The lock has a pair of extensions, a biasing member and a projection that all extend away from the main portion of the body of the lock. The extensions engage a portion of the trigger sprayer and the biasing member provide a restoring force that enables the trigger sprayer to be self-resetting. The projection is capable of being moved by the operator of the sprayer along the trigger lever. When in a raised position, the extensions disengage from a portion of the body of the sprayer placing the sprayer in an unlocked position. However, when the projection is released, the extensions engage a portion of the piston cylinder preventing the piston cylinder from moving and the biasing member automatically force the lock into a lower, locked position on the trigger lever thus rendering the sprayer self-resetting and child-resistant.

Abstract: A vial access spike adapter for connecting a pump dispenser to a vial. The vial access spike adapter is capable of piercing a seal insert in the vial and guiding a dip tube of a pump dispenser into the vial so the contents of the vial can be dispensed directly from the vial. The vial access spike adapter has an upper tubular body with a threaded connection at one end, an annular snap ring connection at the opposite end and a hollow interior throughout. Within the hollow interior, is a central passage used to facilitate the placement of the dip tube into the interior of the vial. A central support is integral with and supports the central passage within the hollow body, and seals the vial access spike adapter to prevent leakage.

Abstract: A flexible dip tube for a liquid dispenser, the tube comprising an elongated integrally formed element having elongated end sections and an elongated intermediate section with a pair of spaced bellows defining flexible/weight portions respectively between one end section and the intermediate section and between the other end section and the intermediate section, one of the bellows functioning as a weight filled with liquid causing the tube to flex at the other end of the bellows.

Abstract: A manually actuated pump sprayer has a cover on the plunger head which is shifted relative thereto, the cover having an opening for exposing the discharge orifice when relatively shifted. In a non-use condition a portion of the cover side wall fluid tightly seals the orifice closed by engaging a circular seal bead provided on the outer face of the orifice cup concentric with the orifice. The outer face of the orifice cup may be textured to increase the hang time of any residual liquid product at that area which is likewise prevented from drying to avoid clogging by the sealed condition presented between the cover and the circular seal bead in the non-use position.

Abstract: A squeeze bottle atomizer comprised of a tube retainer having a product outlet port in a conical shaped central post through which fluid is expelled from within the container. A plurality of air inlet ports are located adjacent the central post and allow air to be forced and sucked out of the container when squeezed as well as return and be sucked into the interior of the container when the container is released. The orifice cup has an annular mixing or turbulence chamber wherein the air and the fluid from within the container are mixed before being expelled out of the orifice cup through a discharge orifice. The axis of the product outlet port is coincident with the axis of the discharge orifice. A dip tube depends from the tube retainer and defines a path for the fluid from the bottom of the container to the annular mixing chamber.

Abstract: A one-piece filter for the distal end of a dip tube of a manually actuated liquid sprayer has an elongated tubular body open at one end with a perforate bottom wall at its other end.
