Abstract:
A directional dispensing package which is easily shipped, filled and assembled is disclosed. The package includes a retaining opening into which a modular pump is snap-fit by inserting the modular pump through an open end of the package. The pump may also be sonically welded to the package. The package also includes a upstanding wall portion, which provides a dispensing actuator locking and sealing mechanism, and can include a tamper-evident tab. The package and pump are assembled at a production site, and are thereafter shipped to a filling site with a bottom portion. The package is filled through the open bottom end, and then the bottom portion is sealingly affixed to the package. The package may include an integrally-molded dip tube structure and a bottom portion with specific structure for allowing easy assembly while preventing leakage. The bottom portion may have an integrally molded dip tube structure. Various devices for allowing inverted dispensing are disclosed. Also, various devices for sealing the spray orifice are disclosed. The device of the present invention can be filled and finally assembled with a minimal number of steps, and is therefore particularly suited for quick-turnaround marketing.

Abstract:
The present invention relates to a dispenser for dispensing medications into the nostril or intravenously. The device has a number of advantageous features. First, the device includes a pump in the outer package, so that it may be used with conventional medication packaging. Second, it includes a stop mechanism for allowing adjustment of the dose to be dispensed. Finally, the device is adapted to be used for both nasal and intravenous dispensing, via a replaceable spray passage or injection needle. The device can also have indicia for indicating when the last dose was dispensed, and can include a disinfecting feature for the spray head. The device can also have a gripping feature which spaces the fingers from the nostril into which medication is dispensed. The package is preferably clear so that the user can determine the quality of the medication being dispensed. The device is particularly useful for dispensing medications such as insulin.
Abstract:
The invention is an atomizing pump for dispensing a quantity of liquid in a fine spray. The pump mechanism is constructed entirely of plastic, including the inlet and outlet valves, the piston, pump housing, and spring. This construction allows the pump to be easily recycled. The pump can also be constructed using two biasing springs. The first spring is used only to return the pump piston; the second spring is used only to bias the outlet valve. In this manner, the person operating the pump only presses downwardly against the force of the first spring, and not the second. As a result of this biasing arrangement, less actuation force is required.
Abstract:
A valving gasket is disclosed for a squeeze bottle sprayer. The gasket includes upper and lower gaskets, each having a vent hole and a flap valve. The vent hole on the upper gasket cooperates with the flap valve on the lower gasket, and the vent hole on the lower gasket cooperates with the flap valve on the upper gasket. The result is that two valved vent paths are created--one for incoming air and one for outgoing air. The incoming air is used to fill the dispenser after squeezing, to equalize pressure in the bottle. The outgoing air is directed through a vent path to a spray chamber and is intermingled with outgoing liquid to create a fine mist spray pattern. The outgoing air vent is small enough to allow escaping air but to prevent exhausting of all pressure during squeezing. The outgoing air flap valve prevents leakage through the outgoing air hole when the bottle is inverted. The upper gasket may also have a flap valve for the outgoing liquid. There is also disclosed a key-keyway arrangement for assisting in assembly of the gaskets so that the valves and holes align.
Abstract:
An actuator for a dispensing pump is disclosed that pressurizes air and releases the air into an internal fluid passage to mix with, and aerate, fluid dispensed from the dispensing pump and expels residual fluid. The actuator has a body portion, an actuating portion biased away from the body portion, and an air chamber formed between the two portions. Force applied to the actuating portion is transmitted to, and serves to operate, the dispensing pump and compresses the actuating portion toward the body portion, pressurizing the air in the air chamber. The pressurized air is selectively released into the fluid passage. Disclosed embodiments employ a dome-shaped resilient membrane and a piston as the actuating portion.

The package includes a retaining opening into which a pump may be snap-fit by inserting the pump through an open end of the package. The package and pump can be assembled at a production site, and are thereafter shipped to a filling site with a bottom portion. The package can be filled through the open bottom end, and then the bottom portion sealingly affixed to the package. The package may include an integrally-molded dip tube structure, which can also serve as the pump housing. The dip tube structure may also be snapped into the package. The dip tube structures of the present invention allow easy assembly while preventing leakage. Various devices for allowing inverted dispensing are disclosed. The device of the present invention can be filled and finally assembled with a minimal number of steps, and is therefore particularly suited for quick-turnaround marketing.
Abstract:
A dispensing container including a interior barrier bag is disclosed, along with a method for filling the barrier bag with a material to be dispensed. The dispensing structure includes a non-vented pump and a dip tube structure, and a mechanism for venting the interior of the container to the atmosphere and for venting the interior of the barrier bag during filling. During assembly and filling, the barrier bag is wrapped or collapsed around the dip tube structure, so that the dip tube structure and the barrier bag can be easily inserted into a conventional container. After insertion, the barrier bag is inflated (with either an air blast or the introduction of the dispensed product) and filled with product. After filling a pump structure can be attached to the container. The method and apparatus allow a barrier bag device to be used on conventionally-designed container structures. The method and apparatus are particularly useful with containers which are made up at least partially of recycled materials.
