| 20110240677 | Airless double-piston double-action pump and cosmetics bottle dispensing device - An airless double-piston double-action pump device comprises a pump assembly, and bottle assembly comprising a volume adjustment piston therein retained by a plug. A nozzle head/valve spool combination is driven from a first to a second position, where the spool openings are exposed beyond a valve seat piston to a cosmetic substance. Continued movement to a third position, ending the down stroke, causes the combination to shrink the reservoir volume and force substance up the spool/nozzle conduit for delivery. During spring-biased nozzle head/spool upstroke, vacuum pressure causes quantities of substance to be drawn upward from the bottle to refill the reservoir, and which also correspondingly causes the bottle piston to adjust vertically. A loose friction fit between the bottle piston and bottle ensures that the bottle piston is static during down strokes, but may be overcome by the vacuum during the spring-biased up stroke. | 10-06-2011 |

Air is discharged from the openings in the body. | 07-23-2009 |
| 20130087583 | GREASE GUN - A lubricant dispenser and an electrical tool. The dispenser includes a housing; a reservoir for containing lubricant; a pump assembly operable to pump lubricant; and a purge assembly including a channel defined by the housing and extending between the reservoir and atmosphere, at least a portion of the channel extending along a channel axis through an opening in the housing and to atmosphere, and a plunger slidable along a plunger axis between a sealed position, in which the reservoir is isolated from atmosphere, and an open position, in which the reservoir is in fluid communication with atmosphere, the plunger axis extending at an angle with respect to the channel axis. The purge assembly may include a biasing member operable to bias the plunger toward the sealed position. The tool may be a dispenser and may include a motor supported by the housing; a trigger; and a trigger lock assembly. | 04-11-2013 |
| 20130341360 | GREASE GUN - An improved grease gun head has a rotating cylindrical lobed channel situated within the head so that the grease gun may utilize its own grease pump to refill its grease reservoir. The channel and configuration of ports may also be modified to remove the need for rotation of the grease channel. | 12-26-2013 |

| 20120024908 | DEVICE TO ALLOW FOR CLEANING ACCESS IN SEMI-SOLID METERING MACHINES - The invention is directed to semi-solid food product metering devices that typically have two counter rotating feed rollers with ends to entrain the semi-solid food product and has an at least one actuating device. The two feed rollers have two roller end plates at each end of the feed rollers, one being at a distal end of the rollers and the other at a proximal end of the rollers relative to the at least one actuating device with an at least one support bar. The feed rollers make a positive seal with the end plates. The semi-solid food product metering device of the invention has an open position and an operating position where the at least one support bar supports the two roller end plates in position while in the operating position and operating the semi-solid food product metering device, and allowing for lateral movement of the end plates away from the ends of the feed rollers to allow access to the gap between the feed roller ends and the roller end plates in the open position. | 02-02-2012 |

| 20110226815 | DISPENSING CONTROL DEVICE FOR ICEMAKER - A dispensing control device for an icemaker includes a dispensing structure and a control structure assembled with the dispensing structure. The dispensing structure includes at least a first dispensing portion and a second dispensing portion for dispensing at least two kinds of materials, wherein the first and the second dispensing portion and the dispensing structure form a dispensing area in which a first position and a second position are defined respectively. The control structure includes a first trigger unit and a second trigger unit, for respectively triggering the corresponding first and second dispensing portion to dispense materials respectively thereof, wherein the first and the second trigger units respectively include a first and a second actuating element mounted at the first position and the second position in the dispensing area, and a first and a second trigger components which are respectively triggered by the first and the second actuating elements to control the material dispensing of the first and second dispensing portion. Therefore, the user can obtain different desired materials by operating at different positions in the dispensing area. | 09-22-2011 |
