Description Referring to FIGS. 1-5, the dispensing package embodying the invention comprises a container 10, a hanger and pouch assembly 11 and a removable head assembly 12 as well as a snap on cap 13.
The container 19 is made of plastic material and includes a side wall 14, an integral bottom wall 15 having an opening 16 and a peripheral annular base 17 forming a foot so that the container can be placed upright on a flat surface.
The container 10 further includes a thread 18 on the upper end and an annular flange 19 below the thread 18 (Fig. 3).
The hanger and pouch assembly 11 includes a pla~tic hanger 20 having a cylindrical body portion 21 an open bottsm end 22 and an integral annular flange 23 extending radially about the open upper end. The hanger 20 further includes an integral annular wall 24 spaced below the flange 23 and integrally connected by radial wall 25 with the interior surface of the hanger 20 and defining an opening.
A plastic ferrule 26 is snapped onto the wall 24, the ferrule having spaced flanges 27 and 28 for retaining the ferrule on the wall 24 (Fig 3A). The ferrule 26 defines an opening 29 for dispensing the viscous product which is supported in a flexible plastic pouch 30 that has an open end 31, a closed bottom end 32, and a cylindrical side wall 33 having and an open end 31 that is bonded to the inner surface of the wall 29 of the ferrule 26 as by heat sealing. The pouch 30 i3 also bonded at spaced areas to the inside surface of the body portion ~0~6~5 21 of hanger 20, preferably adjacent the lower end of the body portion 21.
The head 12 includes a housing 40 having a lower peripheral skirt 41 with internal threads 42 which engage the threads 18 on the upper end of the container 10. The housing 40 supports the pumping mechanism 43, which may be of any well known construction. The pumping mechanism is preferably of the type shown in the aforementioned patent application Serial No.
07/715,187 incorporated herein by reference. The pumping o mechanism 43 includes a transversely extending inner member 44 which is frictionally interlocked with housing 40 by a cylinder 45 which snaps into engagement with spaced internal ribs 46 on the housing 40.
A separate reciprocable, pumping or dosing piston 47. The dosing piston 47 has an integral upwardly extending portion 48. The upwardly extending portion 4~ of the dosing piston 47 extends through an opening in the end member 44 and is within such opening. The upwardly extending portion 48 of the docing piston 47 includes a collar 49 which is coaxially fitted thereto and which is in telescopic slidable communication with the inlet portion 50a of the dispensing spout 50 of the housing 40 to permit product to be dispensed from the container throughout the range of travel of the dosing piston 47. An outlet portion 50b of the dispensing spout 50 extends obli~uely from the inlet portion 50a, which is coaxial with the longitudinal central axis of the container and the upwardly extending portion 48 of the dosing piston 47. The orientation of the inlet portion i9 best sulted for the flow of product ~rom within the body and the orientation of the outlet portion provides that the product will be dispensed at a location which i~ quite convenient for a user who is grasping the package for application to an article such as a toothbrush.
An integral one way valve 51 is provided adjacent the lower portion of the dispensing chamber D adjacent the opening in the ferrule 26 which cooperates with a radial wall 55 of the ferrule 26 to provide a qeal. Valve 51 is shown in FIG. 5 and comprises a flat annular disk 52 connected to the inwardly extending annular flange 53 on the skirt of the cylinder wall 45 and having an annular bead 54 on the under surface thereof engaging a radial wall 55 on the ferrule 26 to provide the seat.
In accordance with the invention, a second one way valve 56 is provided on the collar and is preferably of the construction shown FIGS. 4A, 4B and 4C wherein the valve i9 molded by injection molding in the configuration shown in Fig.
4C and includes an annular wall 57, a sealing flap 58 connected b~ an integral hinge 59 to the annular wall. After molding, the hinge is bent to bring the hinge 59 into an axial groove 60 and the disk 58 into the position shown in FIG. 4b where the memory of the plastic holds the disk 58 yieldingly against an integral annular axially extending seat 61.
In order to assemble the package, the hanger and pouch assembly 11 are first inserted in the container 10 and the flange 23 on the hanger 20 engages the upper end of the container 10. The pouch is then filled with product through the ferrule 26. The head assembly 12 i9 then threaded onto the container and thereby holds the hanger and pouch assembly in position.
A dose or shot of product from the container 10 is dispensed by moving the dosing piston 47 downwardly. This pressurizes the product in chamber D in a way which can only be relieved by the flow or displacement of product outwardly from the chamber D, given the one-way limitation on the travel of the valve 51. The downward movement of the dosing piston 47 is actuated by a pumping lever 65 which is carried by the housing o 40 and which is oscillatable with respect to the head portion 16 about opposed coaxial axes tnot shown) on housing 40. The pumping lever 65 is preferably of a different color than the housing 40 to be readily distinguishable therefrom.
To initiate a dispensing cycle, a finger engaging portion of the pumping lever 65 is moved by finger force through a limited arc in a clockwise direction in the orientation of the package 14 as viewed in FIG. 2. This action lifts a tip portion 65a of the pumping lever 65 clear of the outlet portion 50b. The clockwise movement of the pumping lever 65, as described, also moves the piston 47 downwardly. After the desired amount of product has been dispensed from the container, the finger force is removed from the pumping lever 65. A spring 60 will then return the pumping lever 65 to its original position, substantially closing the tip of the dispensing spout 50b, to await the next dispensing cycle. This will also cause the second one-way valve 56 to close and the valve 51 to open so 2 0 (~ a that viscous product can be drawn by the reduced pressure into chamber D to replenish the product dispensed.
After all or subqtantially all product haq been dispensed from the body portion 18 in a multiplicity of doses or shot~, each of a relatively small mass, the container 10 and head 12 may be disengaged from one another. The exhausted hanger and pouch assembly 11 can be removed and a fresh hanger and pouch assembly 11 be inserted. The head portion 10 can then be reapplied. The replacement hanger and pouch aqsembly 11 includes a removable clo~ing member C (FIG. 9).
In the modified form of di~penser package shown in FIG. 6, the construction i9 identical to that in the form shown in FIGS. 1-5 except that the container lOa has a separate bottom member 16a and is formed with a thickened portion lOb on the outer wall 15a to provide a foot for engaging a flat surface.
The container lOa further differs in that the upper end thereof has a shoulder lOc adjacent the threaded portion. In all other respects the inner is the same~
In the form shown in FIG. 7, the construction is substantially identical to that shown in FIGS. 1-5 except that the bottom wall 16b of the container is made as a separate part and includes spaced axial walls 16d, 16e defining a groove into which the lower end of the container lOd extends.
In the form shown in FIG. a, the ferrule i~ omitted and the pouch is sealed directly to an integral vertical wall 70 on the hanger.
This i9 a continuation-in-part of application Serial No. ~7/759,328 filed September 13, 1991.
