The apparatus includes an attachment having a pump sprayer that is pressurized on the upstroke. The attachment includes a body that defines a chamber, a shaft moveable between a first and second position in the body, a piston, a first valve and a second valve. The first valve permits the flow of fluid into the chamber and restricts the flow of fluid out of the chamber. The second valve moves between an open position-permitting the flow out of the chamber and a biased closed position restricting the flow out of the chamber. When the shaft is moved to the first position, the shafts moves the second valve from the closed position to the open position. An apparatus with a bleeder orifice for automatically releasing pressure is also disclosed.

Abstract: A capped container is disclosed, which includes a container body, a nozzle, a cap, and retainer means provided between the inside wall of the cap and the shoulder or nozzle tip of the nozzle for enabling the nozzle to be press-fitted first into the cap and then fastened to the opening of the container body with the cap. When holding the cap to aim the nozzle at the opening of the container body, the punch of an automatic machine is pressed on the top of the cap to force the nozzle into engagement with the opening of the container body without causing damage to the nozzle.

Abstract: An anti-float plunger for a pneumatically actuated syringe includes an inner cylindrical ring with two open ends held within a cylindrical cover having one open end and one closed end. The open end is at the backside of the plunger. The closed end is at the frontside, in contact with liquid to be forced through the syringe outlet. The cover includes an outer flexible wiper extending around the circumference. This wiper maintains an airtight seal with the syringe walls even when the walls bulge outwardly due to excessive backside pressure. The cover also includes a deformable membrane at the closed end, which deforms away from the outlet to alleviate residual pressure buildup on the liquid in the frontside. This structure eliminates air entrapment within the syringe, while also preventing residual pressure buildup within the syringe.

Abstract: An aerosol container for dispensing adhesives under pressure is retrofitted with an adapter means for preventing clogging of the discharge valve with old adhesive after use. The adapter means comprises an interior sleeve inserted within an exterior dispensing tip where the assembly is retrofitted into the discharge valve of the aerosol container. A trigger mechanism attached to the top of the aerosol container engages the aerosol can discharge valve to facilitate bias engagement of the discharge valve of the aerosol container.

Abstract: A limited pour neck finish bottle wherein a plurality of radially inwardly extending flexible fingers are integral with the peripheral edge portion of the open end of the neck of a bottle and extend across the open end of the neck to restrict or interfere with the flow of liquid from the bottle if an attempt is made to pour the liquid from the bottle rather than employing an exact dose dispensing device. The bottle is made by molding a plurality of axially extending flexible fingers on the peripheral edge portion at the open end of the neck simultaneously with the molding of the bottle, and then bending the fingers downwardly to the radially inwardly extending position.

Abstract: A product dispenser for compelling a product from a container is provided having a frame with opposed end walls defining first and second axially aligned sockets and a dispensing hole. An drive member with first and second opposed ends is releasably engaged by the first and second sockets, respectively. A bearing member is adapted to travel between the first and second opposed ends of the drive member, whereby a deformable container holding a flowable product inserted into the frame expels the product through the dispensing hole under pressure exerted upon the container by the bearing member. The drive member is releasable from the frame and is re-engaged by the frame, whereby the first and second opposed ends are then releasably engaged by the second and first sockets, respectively. Therefore, after the bearing member has traveled from the first end to the second end, the bearing member may be repositioned within the frame to reinitiate travel towards the dispensing hole.

Abstract: A pressurized tank dispenser assembly generally includes an extractor valve and a relief valve component mounted on a common fitting which may be held to a tank by a securement ring. The extractor valve permits pressurizing the tank and dispensing liquid by the attachment of a coupler thereon without the need for tools, while the relief valve component includes both vacuum relief and overpressure relief valves. The fitting is attached to the tank by the annular securement ring, whereby only a single opening through the tank is necessary to perform all operating functions of the tank.

The apparatus desirably includes an attachment having a pump sprayer which is pressurized on the upstroke enabling the sprayer to be shipped and stored in a relaxed position. The attachment includes a body, a coupling, a shaft, a piston, an inlet valve and a biasing member. The body defines an elongate chamber having the first end, second end, and an interior wall extending between the first end and second end. The coupler is sized and shaped to secure the body to the neck of a container. The shaft extends through the opening in the first end of the chamber and defines an internal flow channel. The piston is reciprocally mounted within the chamber and includes an inner annular surface surrounding the shaft and an outer annular surface sized and shaped to form a sealing engagement with the interior wall of the body.

The concentrate cartridge is caused to open by the rotating engagement of a closure cap on the diluting and dispensing container to which causes the closure portion of the hollow tube to disengage to release the concentrate material.

Abstract: A liquid sprayer incorporating an air pump to force pressurized air into the interior of a receptacle. The air pump is operated, by stroking of a cover. The cover has an opening allowing finger access to the plunger of a spray nozzle in one rotated position of the cover, the cover being held in that position. In another rotated position the cover is released for stroking. A piston on the cover projects into a central tubular portion on the cap with valving sealing allowing air to be drawn past the piston and forced into the receptacle. The spray nozzle is offset from the tubular portion and the plunger is accessible through the cover without removing the same.
