DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The preferred embodiment of the present invention includes a flexible pouch having a fitment at the top. The fitment includes a canoe portion to which the panels of the pouch are affixed. The fitment includes a spout with a channel which extends vertically through the canoe portion and connects to a tube portion of the metering pump. A cap is mounted by a living hinge on top of the canoe portion. The metering pump is suspended from the bottom of the canoe portion to draw the contents of the pouch into the spout and through the channel and out through the cap portion.
FIG. 1 illustrates a first embodiment of the assembly having the pump portion on a partially exterior portion of the pouch. A second embodiment of the pouch is also illustrated in FIG. 5. A third and preferred embodiment is illustrated in FIGS. 6-8.
A fitment for dispensing fluid from a flexible pouch is provided where the fitment includes a pump and a canoe portion having a passage in fluid communication with the pump, the canoe portion having side walls mounted to the flexible pouch whereby activation of the pump draws fluid from the pouch and through the passage to dispense the fluid.
In reference again to FIG. 1, an assembly 10 having a cap portion 12 and a flexible pouch 14 is disclosed. The assembly 10 further includes a metered dispensing pump 16. The pump includes a dome shaped press button 18 and side walls 20, 22. A first embodiment of a pump capable of being used in all embodiments will now be described. The pump includes a lower portion below the canoe of the fitment which has an orifice to receive fluid from the pump into a large cavity in the lower portion which tapers to a narrow channel which extends through the canoe of the fitment. In an alternative embodiment (such as shown in FIG. 6), the dome portion draws and holds the predetermined amount of fluid. A passageway connects the dome to the outlet of the pump directly in one straight passageway. When the user presses the dome a second time, the predetermined amount of liquid is dispensed.
A base plate for the pump extends downwardly on the side of a lower portion of the pump. The base plate may be molded integrally with the fitment or heat welded to the fitment. The pump has a top portion secured to the base plate. The top portion has a ring surrounding a dome which extends over a one-way flapper valve. A passage extends from the dome along the base plate to the spout orifice. When the dome is depressed, air or fluid is expelled from the cavity under the dome and on its release fluid from the pouch is drawn into the cavity through the flapper valve and forced through the passage of the orifice and into the spout upon a second depression of the pump.
Accordingly, now in reference to FIG. 1, when the dome 18 of the pump 16 is depressed, air is expelled from the pump portion. When the dome is released, fluid from the interior of the pouch is drawn into the holding portion of the pump. Upon a second depression of the dome 18 of the pump 16, fluid is moved out through the orifice or opening of the fitment and cap 12. This movement is illustrated by directional arrow 36.
The pouch 14 is formed by joining two panels at an outer seam (to form a sleeve). The outer edges of the panels are heat welded or otherwise connected to form a pouch-like configuration.
