Abstract: The invention includes a method of using a cap containing an internal thread form matching an external thread form on a flexible throat for a collapsible tube enclosing at least one contained product. Twisting the cap engages the internal thread form and the external thread form. These collectively urge the cap and the flexible throat to seal the contained product into the collapsible tube. Deforming the flexible throat through squeezing the collapsible tube dispenses essentially all the product. The collapsible tube may preferably include an external thread form on a flexible throat coupled to a flexible shoulder. The external thread form mates to a cap with an internal thread form urging the flexible throat to seal against the cap when the cap is twisted onto the flexible throat. The flexible throat and flexible shoulder flatten to dispense essentially all of the product.

Abstract: An apparatus for discharging dry bulk material by aeration having a substantially annular flexible aeration liner supported by a substantially cone-shaped perforated hopper, which is affixed to an air disc assembly, whereby air introduced into the air disc assembly is distributed evenly through the perforated hopper that supports the aeration liner that tends to fluidize dry bulk material, thereby allowing the material to discharge.

The fluid supply is adapted to be in selective communication with either or both the fixed and removable fluid dispensing units, such as through the provision of a fluid diverter element located at an inlet of the fixed unit and from which extends a conduit in separate communication with the removable unit.

Abstract: A heated dispense pump overcomes the limitations of conventional systems providing for reliable and efficient heating of the dispensed material in a system that is compact, lightweight, and accurate. A pump housing and cartridge body are formed of a thermally conductive material such as copper, aluminum, or an alloy combination thereof. A heater element is applied directly to the body of the pump housing, and a thermocouple is included to provide for closed-loop controllability. The material flows though the cartridge body and is heated prior to release at the dispense tip. The heated elements, including the pump housing and cartridge body, are thermally insulated from the pump motor and pump gantry to prevent the escape of heat from the system and to protect those adjacent components from heat damage. An optional syringe heater is provided for heating the material in the syringe, and for controlling the temperature of the material, in closed-loop fashion.

Abstract: A fluid dispensing apparatus comprises a collapsible bag capable of being punctured by and essentially sealed about a spike that has an inlet through which fluid can flow from the bag into a conduit leading to a chamber that is situated within an enclosed chamber in a dispensing base unit. The chamber is connected to a valve positioned outside the enclosed chamber through which fluid can be dispensed from the chamber. The enclosed chamber is vented so that as fluid is dispensed from the chamber, the air pressure in the enclosed chamber is allowed to equalize with the ambient air pressure external to the chamber and the bag.

Abstract: A venting system of a manually operated trigger sprayer vents the interior of a liquid container connected to the trigger sprayer. The trigger sprayer is provided with a vent chamber that surrounds the pump chamber, and a vent piston that surrounds the pump piston. The vent piston is received in the vent chamber for reciprocating movements with the pump piston in the pump chamber. The reciprocating movement of the vent piston alternatively opens the vent chamber to the exterior environment of the trigger sprayer and thereby vents the interior of the liquid container connected to the trigger sprayer, and closes the vent chamber thereby sealing the interior of the liquid container from the exterior environment.
