222336000 | With biasing means for discharge assistant and/or its casing | 13 |
20110303702 | Liquid spray head assembly - A spray head assembly includes a push member, a piston rod, a spring, a seal member, a link, a movable member, a cylinder and a resilient valve. The link includes multiple axial slots defined in an outer surface thereof so that no surplus and rough material is left during manufacturing. The spiral valve effectively responses the operation of the spray assembly to seal or open the path in the cylinder. | 12-15-2011 |
20130264359 | One Turn Actuated Duration Spray Pump Mechanism - A power assembly that can obtain duration discharge of product upon a single turn of an actuator sleeve to pressurize product and ready it for dispensing. The assembly includes a piston carried by a piston housing for reciprocation in a cylinder cup having a pump chamber. The actuator sleeve is connected through a clutch disc to a drive screw that is connected to reciprocate the piston housing and piston when the actuator sleeve is rotated. The clutch disc is operative to first disengage the actuator sleeve from the drive screw and then move a stem valve to an open position when an actuator is depressed to dispense product. The power assembly can be used with various energy storage devices such as springs, gases or elastics to exert pressure on product to be dispensed when the actuator is turned. | 10-10-2013 |
20140103074 | DRIPPING PREVENTION APPARATUS IN SEALER GUN - A sealer gun that discharges a liquid material of a coating agent/a filler from a nozzle on its tip is securely prevented from producing dripping that arises as a liquid material drips from the tip of the nozzle and remains when a discharge of the liquid material is stopped. | 04-17-2014 |
20160136665 | SPRAYER FOR LIQUIDS WITH USD DEVICE THAT CAN BE USED ALSO IN HORIZONTAL POSITION - A sprayer for liquids ( | 05-19-2016 |

20090152304 | Break-Away Spring and Piston Rod for a Trigger Sprayer - A manually operated trigger sprayer has an integral plastic spring and pump piston rod that are connected by a breakable connection, whereby the spring and piston rod can be assembled to the trigger sprayer as one piece and are subsequently broken into two separate pieces in response to their assembly to the trigger sprayer, or subsequent manual operation of the trigger sprayer. | 06-18-2009 |
20110278328 | DISPENSING PUMP - Disclosed is a dispenser pump mounted to an opening of a container to allow a user to dispense a cosmetic product accommodated in the container to the outside by a predetermined amount through a pumping operation. In order to achieve this object, there is provided a dispenser pump for allowing a user to dispense contents by a predetermined amount through a cylinder ( | 11-17-2011 |
20140091110 | DISPENSING DEVICE - A dispensing device is disclosed having a cylinder, a piston disposed in the cylinder and moveable in priming and dispensing directions, including a spring device biasing the piston to move in the priming direction at a predetermined rate, and an operating plunger connectable to the piston and moveable along a path to move the piston in the dispensing direction. The operating plunger has an engagement device and is moveable between an engaged position in which the engagement device is connected to the piston and movement of the plunger along the path is transmitted to the piston, and a disengaged position in which the engagement device is disconnected from the piston and movement of the plunger along the path is independent of the piston. The engagement device is arranged such that movement of the plunger between the engaged and disengaged positions is of a different kind to movement along the path. | 04-03-2014 |
20150014362 | LIQUID MATERIAL DISCHARGE DEVICE AND DISCHARGE METHOD - The present invention provides a discharge device ( | 01-15-2015 |
20150342706 | DISCHARGING DEVICE - A dispensing apparatus for a flowable component includes a storage container having a storage chamber for the reception of the component, a filling opening and a dispensing opening. A piston is displaceably arranged within the storage container in the direction of an expulsion direction. Moreover, dispensing apparatus includes an actuation element by which the piston can be displaced stepwise in the direction of the dispensing opening. After release of the actuation element actuation element is displaced from a final position into a starting position by a spring. | 12-03-2015 |
20160136670 | CONTENTS DISPENSING PUMP - The present invention relates to a contents dispensing pump used by being mounted in a container so as to dispense, to the outside, contents accommodated in the container by a fixed quantity through a pumping operation and use the same, and particularly, to a contents dispensing pump which can: increase productivity and lower a product price by allowing a deformed pressing member to function as a cylinder and an opening and closing valve so as to simplify a structure of the contents dispensing pump; and at the same time, be easily mounted in a product having a small space in which the dispensing pump is to be mounted, by performing a pumping operation by changing the volume of a temporary contents reservoir due to a deformation of the deformed pressing member such that a working stroke distance of the dispensing pump can be short. To this end, the present invention relates to the contents dispensing pump which is coupled to a container for accommodating the contents therein and dispenses the contents, wherein a deformed pressing member ( | 05-19-2016 |

20150090741 | Compression Spring and Pump for Dispensing Fluid - Springs having various configurations include upper and lower connecting members and spring elements extending therebetween. The configurations of the springs may enable them to be formed of polymeric material such as by injection molding. Pumps for pumping fluid or adapted for other uses may include such springs and may include interfacing arrangements with the springs. | 04-02-2015 |
20160129463 | Surface Tension Condiment Dispenser - A condiment dispenser dispenses a portion of a condiment held within a reservoir. The condiment dispenser includes a housing that defines the reservoir and a piston assembly that is translatable within the housing between a first position and a second position. A chamber insert is connected to a dispensing end of the housing and the chamber insert includes an insert bottom wall and at least one orifice extending through the insert bottom wall. A sealing ring is engageable with the seat of the piston assembly and a bottom wall includes at least one nozzle and is disposed below the chamber insert to define a void between the bottom wall and the insert bottom wall. | 05-12-2016 |
