20080223875 | DISPENSER WITH DUAL PUMP SYSTEM - A fluid dispenser is provided that includes a multiple chamber fluid storage region, each having a dispensing pump of its own such that the dispenser can dispense the fluids from within the multiple fluid storage regions. Further, the multiple fluid storage regions may each contain the same or different liquids. The dispensing pumps include a metering housing, which when depressed, generate a one-way flow from the interior fluid storage region of the container that serves to fill the predetermined volume of the chamber within the metering housing. When the metering housing is depressed a second time a substantially equal volume of each of the fluids is dispensed from the container, while upon release, the metering housings are refilled by drawing fluids from their respective fluid storage regions. The fluids are mixed in the exit port as they are dispensed from the metering pumps. | 09-18-2008 |
20080237262 | HANGING LIQUID DISPENSER - A hanging liquid dispenser is provided that includes a pump and valving for delivering the fluid material when the dispenser is operated by the user in a controlled fashion. The hanging dispenser includes a main body that serves as a fluid reservoir and has an eyelet formed therein which is suitable for use in hanging the dispenser from a suitable support. In addition to including the ability to hang, the dispenser preferably includes a pump for metered dosing of the fluid within the dispenser wherein operation of the pump delivers a controlled volume of the fluid as desired by the user. | 10-02-2008 |
20080264972 | METERING DISPENSING SYSTEM WITH IMPROVED VALVING TO PREVENT ACCIDENTAL DISPENSING OF LIQUID THEREFROM - A liquid dispensing device includes a storage container and dome pump mechanism attached thereto for metered dispensing. A one-way valve is employed to pull liquid from the storage container into the dome for metering. An exit passageway serves as an output valve. Each time the dome pump housing is depressed, a substantially equal volume of fluid is dispensed from the container. To prevent accidental dispensing, the one-way valve in the dome pump remains normally open and unsealed to allow backflow of liquid back into the storage container pouch when pressure is placed on the dome. The user squeezes the dome and base plate together to seal the one-way valve to urge liquid out through the exit port for actual dispensing. Also, interior pouch force creates blackflow through the exit port back into the containment chamber to further prevent leakage. | 10-30-2008 |
20080264973 | METERING DISPENSING SYSTEM WITH IMPROVED VALVING TO PREVENT ACCIDENTAL DISPENSING OF LIQUID THEREFROM - A liquid dispensing device includes a storage container and dome pump mechanism attached thereto for metered dispensing. A one-way valve is employed to pull liquid from the storage container into the dome for metering. An exit passageway serves as an output valve. Each time the dome pump housing is depressed, a substantially equal volume of fluid is dispensed from the container. To prevent accidental dispensing, the one-way valve in the dome pump remains normally open and unsealed to allow backflow of liquid back into the storage container pouch when pressure is placed on the dome. The user squeezes the dome and base plate together to seal the one-way valve to urge liquid out through the exit port for actual dispensing. The dome pump is integrally formed with a top portion of the exit pathway. Optionally, the base plate and bottom portion of the exit pathway are also integrally formed to facilitate manufacture and reduce costs of the pump while improving performance thereof. | 10-30-2008 |
20090183371 | Razor With Integrated Dispensing of Shaving Treatments - A shaving apparatus includes a main body, a shaving head attached to the main body and an integrated mechanism for dispensing the shaving treatment disposed within the main body. The integrated mechanism includes a pouch defining a reservoir containing the shaving treatment, at least a portion of the pouch being flexible such that the reservoir decreases in size as the shaving treatment is withdrawn therefrom, a flexible button at least partially defining a metering chamber in fluid communication with the reservoir, an output one-way valve in fluid communication with the metering chamber and permitting unidirectional flow of the shaving treatment from the metering chamber when the flexible button is pressed by the user and an intake one-way valve disposed between the metering chamber and the reservoir and permitting unidirectional flow of shaving treatment from the reservoir into the metering chamber when the flexible button is released by the user. | 07-23-2009 |
20090263176 | Replaceable Cartridge Dispenser Assembly - In accordance with one embodiment of the present invention, a fluid dispensing device includes a housing having a wall defining an interior compartment, the wall having an opening passing therethrough, and an exit port located therein or thereon, and a replaceable cartridge dispenser assembly disposed within the interior compartment. The replaceable cartridge dispenser assembly includes a fluid reservoir containing a fluid and a metered dispensing pump integrally formed with the fluid reservoir, the metered dispensing pump in fluid communication with the fluid reservoir and with the exit port of the housing and including a button, actuation of which causes metered dispensing of the fluid within the fluid reservoir to the exit port. The button is accessible through the opening in the wall of the housing, and the cartridge assembly, including the fluid reservoir and the metered dispensing pump, is replaceable as a unit such that the housing is reusable. | 10-22-2009 |
20090266834 | Snap closure - A snap closure for a container includes an annular snap bead in a skirt portion. A top portion extends upwardly from the skirt portion, the top portion having horizontal slits. When the snap closure is engaged with a container, the snap beads snap onto a mating locking ring of the container. An upwards force is applied to the snap closure to disengage the closure from the container. The horizontal slits enable the top portion to flex axially to provide additional rotational leverage for disengaging the snap beads from the annular locking ring. | 10-29-2009 |
20110027507 | Multi-Layer Product With Sealing Areas Of Varying Temperature - An article of manufacture that has at least three layers of heat sealable material. There is at least one first heat seal between at least two of the layers in a first area effected at a first temperature. There is also at least one second heat seal between at least two more layers, where at least one of these two layers is distinct from the at least two layers joined by the first heat seal, in a second area effected at a second temperature, where the second temperature is different than the first temperature, thereby allowing for heat sealing of discrete areas of the article in discrete steps. | 02-03-2011 |
20110027508 | Multi-Layer Product With Sealing Areas Of Varying Sealing Affinities - An article of manufacture that has at least three layers of sealable material.

20130146227 | Variable Temperature Seal Element - Devices and methods for fusing materials using a heating element, where the overall mass to be sealed varies along the length of the seal. According to the invention, the heating element has a different profile in different areas. According to some aspects, the thickness and/or cross section of the heating element is different in different areas so that when a current is passed through the heating element, each area heats to a different degree. In some aspects, the heating element is shaped to conform to the shape of the parts to be fused together. The transition between areas of different thickness or cross-sectional area, or between areas of different shape may be sharply defined. This abrupt transition may be created by machining the heating element to a finished shape rather than bending flat stock to shape. | 06-13-2013 |
