摘要:
A container and associated dispenser for liquid is configured to dispense residual liquid from the container after the bulk of liquid has been dispensed from the container. This is accomplished by having a conical projection on the bottom of the container which causes residual liquid to flow into a gutter defined by the wall of the container and the surface of the conical projection. A dip-tube is connected to the dispenser and is rotatable in order to revolve the open free end of the dip-tube to access any circumferential location in the gutter in order to pick up residual liquid.

An apparatus and method for accurately measuring and dispensing a predetermined amount of product from a dispensing system to a given surface area is disclosed. The dispensing system (100) includes a container (102) having a main chamber (106) to hold product and a dosing chamber (108) having an opening (110) in communication with the main chamber (106). The dosing chamber (108) is configured to hold a metered amount of product (112) received from the main chamber (106). A spray head (128) when connected to the container (102) is brought into operable and fluid communication with a dip tube (114), optionally cut to a selected length, which is positioned within the dosing chamber (108) for dispensing by activation of a trigger (136) product (112) to a given surface area or air space.
摘要:
A trigger pump dispenser comprises an outlet valve which is adapted to open an outlet port when a pump chamber decreases in volume as liquid therein is dispensed through the outlet port, and which is adapted to close when the pump chamber increases in volume. The outlet valve comprises a precompression valve operable to allow liquid through the outlet only after a predetermined elevated pressure is established in the pump chamber. The valve has a movable valve member carried on or by a spring member which biases the valve member to a closed position but flexes in response to the elevated pressure in the chamber acting on the valve member to move the valve member to an open position so that liquid can pass from the chamber and thereafter be dispensed through an outlet nozzle.

A discharge pump equipped with a push-down head in which a nozzle is opened and closed by advancing and retracting a valve rod member by a lever member and a first pressing member, wherein a second pressing member is provided between the base and the tip of the valve rod member to prevent back flow of air. A push-down head discharge pump has a head body configured by providing a liquid flow pipe to the lower surface of a laterally facing cylinder section so as to extend vertically downward from the lower surface, the liquid flow pipe communicating with a stem of a discharge pump, the cylinder section having a nozzle opened at the front thereof. When the head body is pushed down, a valve rod member mounted in the cylinder section is advanced and retracted. The valve rod member is composed of the base and the tip, and a second pressing member is mounted between the base and the tip.

A dosing head for dispensing a fluid from a container is presented. The dosing head has an inlet opening connected to the container, an outlet opening connected to the inlet opening via a conduit, a pump provided in the conduit, and a aerating opening. The dosing head can be used in an upside down position. A liquid seal is arranged between the aerating opening and the container. The seal can include an aerating channel that is rotated twice through about 180° and which can be assembled from two mutually connected parts. The liquid seal can have a restriction which prevents liquid form reaching the aerating opening when upside down.

According to one aspect of the present invention, a liquid reductant tank for supplying liquid reductant to a selective catalytic reduction system is disclosed. The tank includes a tank cavity for holding a liquid reductant and being at least partially defined by one or more side walls; a liquid reductant supply line at least partially situated within the tank cavity and for communicating liquid reductant from the tank cavity to outside of the tank cavity; and a heating element situated at least partially within the liquid reductant supply line and for thawing frozen reductant situated within the supply line during cold start conditions to obtain liquid reductant for use in a selective catalytic reduction system.
摘要:
A trigger dispenser device for a liquid provides an integral valve element comprising a suction duct and at least one flexible suction lip to obstruct the suction duct during the dispensing phase, and an annular obturator and a flexible flange supporting it, for opening the pressure chamber toward the dispenser duct during the dispensing phase.

摘要:
Described is a multi-chamber fluid dispensing container with multiple dip tubes, and a package including the container and trigger sprayer having multiple supply lines for fluid connection to the multiple dip tubes. The container includes a body having a first wall defining a first interior volume and a second wall defining a second interior volume, a first dip tube fluidly connected to the first interior volume, and a second dip tube fluidly connected to the second interior volume. The package may include the container and a trigger sprayer coupled to the container, and fluidly connected to the first dip tube and to the second dip tube. Other embodiments may also be disclosed and claimed.
摘要:
A closure for a liquid container is provided between the container and a liquid dispenser head. The closure includes an intermediate body between the dispenser head and the container. The dispenser head can be rotated with respect to the container, without unscrewing the closure, except when the intermediate body is manually prevented from rotating.
