PRESSURIZED DISPENSING DEVICE Filed April 8, 1964 FIG.|.

FIG.3.

INVENTOR John P. Modderno United States Patent 3,255,924 I PRESSURIZED DISPENSING DEVICE John Paul Modderno, Gambrills, Md., assignor to Modern-Lab., Incorporated, Baltimore, Md., a corporation of Maryland Filed Apr. 8, 1964, Ser. No. 358,311 8 Claims. (Cl. 222--82) The present invention relates to a compartmentalized pressurized dispensing device for keeping two or more materials separated from each other until time of use. More particularly, this invention relates to a pressurized container in which two or more materials are kept separated from each other, and are combined before dispensing from the pressurized device.

It will be appreciated that there are various compo-sitions which cannot be marketed in premixed form. Such compositions as dental impression formulas, polyurethanes, rubberized silicones, epoxies, polystyrene foams, and certain other two or more component systems cannot be mixed until use because the mixing causes an immediate chemical reaction, making the pressurized container inoperative. Materials of this type require a special packaging and dispensing device in order to maintain the portions distinct during shipment and in storage prior to sale, and yet allow the portions to be brought together in a convenient manner when their use is desired.

The present invention is directed broadly to the dispensing of all types of compositions of the abovementioned character and it has found further utility for foods, insecticides, lacquers, paint compositions, and the like, which, to be effective as usable products, must be mixed in situ when use is desired. It is essential in the commercialization of such products that the reactive ingredients be held in a state of inactivity for an indefinite period of time to account for shipping and storage periods, to provide an effective product when needed.

The dispensing device of this invention meets these needs by providing partition means which divide the container into two or more separate compartments. Cutting means operatively connected to the discharge nozzle of the dispensing device are effective to cut a plastic Wall portion separating the compartments so that the ingredients may be mixed prior to dispelling for the intended use.

One of the primary objects of the present invention is to provide a compartmentalized dispensing device suited for packaging compositions, the ingredients of which should be kept separate until use.

Another object of the present invention is to provide a compartmentalized dispensing device in which means facilitating the mixing of the separated ingredients are operatively connected to the discharge nozzle assembly 'of the dispensing device.

A further object of the present invention is to provide a compartmentalized dispensing device which can be produced efficiently and economically.

The above and other objects, features, and advantages of the invention will become more apparent from an examination of the drawings, specification, and appended claims.

In the drawings:

FIGURE 1 is an elevational cross-sectional view of one embodiment of a compartmentalized dispensing device of the present invention;

FIGURE 2 is a view similar to FIGURE 1 but showing the cutting means in the process of cutting the container partition means;

FIGURE 3 is a horizontal cross-sectional view taken along the line 33 of FIGURE 1; and

FIGURE 4 is a horizontal cross-sectional view taken along the line 4-4 of FIGURE 2.

3,255,924 Patented June 14, 1966 tainer has a cup-shaped cover 12 fitting into the upperopen end of container 10 and clinched by a rolling flange 14 to provide an hermetic seal between cover 12 and container 10. The top of cover 12 defines a central aperture which is bounded by a rolled flange or bead 16. An

annular insert 18 fits within the aperture and is provided with a rolled flange 20 which embraces the bead 16 to form an hermetic seal at this point. Insert 18 has an annular bottom 22 adapted to be received and retained within a groove in an annular gasket 24..

Rotatably positioned in annular gasket 24 is a discharge nozzle 26 which has a flared flange 28 providing an abutment for the upper end of gasket 24. At the lower end of discharge nozzle 26 there is formed a valve unit consisting of a plurality of apertures 29 which provide access to the interior of the discharge nozzle, and a valve stem 30 which in its normal position is in sealing engagement with a valve seat 32 formed by the bottom end of gasket 24. It will be appreciated that a lateral force applied to deflect the upper end of discharge nozzle 26 in directions as shown by arrows 33 in FIGURE 2 is effective to unseat valve stem 30 and to establish a flow path from the interior of container 10 through apertures 29 into discharge nozzle 26. Integral with valve .stem 30 is a downwardly depending rod 34.

A sealed plastic sac 36 is positioned within container 10 with its upper end fastened to gasket 24 by an adhesive or other suitable securing means and with its lower end fastened adjacent the free end of rod 34 by an adhesive or other suitable securing means. Sac 36 may be constructed of any plastic material which is impervious to the ingredients stored in the container. It has been found that the sac may be made of a Mylar film, a highly durable, transparent, water-repellent film of polyethylene terephthalate resin characterized by outstanding strength and chemical inertness. Many other materials may be used to form the sac, e.g., polyethylene, nylon, and the like. The thickness of the sac will depend, of course, upon the condition under which the pressurized container is to operate.

A suitable puncturing device or cutter 38 is mounted on rod 34 at the underside of valve stem 30. Upon manual rotation of discharge nozzle 26 in the direction shown by arrow 40 of FIGURE 2, cutter 38 is rotated in the direction shown by solid arrows 42 of FIGURE 4 to cut or otherwise rupture sac 36 so that the ingredients within the container may be mixed just prior to utilization. If discharge nozzle 26 is rotated in the opposite direction, cutter 38 will take the path shown by dashed arrows 44 of FIGURE 4. It will be appreciated that prior to rupturing sac 36, cutter 38 is maintained in an inoperative position away from sac 36. The frictional engagement of the discharge nozzle within annular gasket 24 inhibits inadvertent contact between cutter 38 and sac 36.

Sac 36 may optionally be secured in any other suitable manner so as to be in position to be ruptured by cutter 38. For example, the upper end of the sac might be secured to annular insert 18. It is also within the scope of the invention to fasten only one end of sac 36. In the event that more than two ingredients are to be combined, a plurality of'sacs 36 may be provided.

When not in use, discharge nozzle 26 may be covered by a suitable cap (not shown).

In operation, container 10 is partially filled with one of the ingredients to be discharged. In the case of a twocomponent system, the other ingredient is placed within sac 36 which is fastened in position by suitable securing means to a sub-assembly consisting of insert 18, gasket 24, discharge nozzle 26 and the associated structure. This sub-assembly may now be hermetically sealed to cover 12 which is then in turn hermetically sealed to container 10. The assembled container may be pressurized in known manner with a propellant such as one or more of the Freons, nitrogen, argon, or other suitable inert gas. The container in this condition may be stored until use is desired, whereby unscrewing of the cap, and manual rotation of discharge nozzle 26 causes cutter 38 to rupture sac 36 readying the container for use. Pressing the discharge nozzle laterally unseats valve stem 30, thereby discharging material from the container as desired.

Although the present invention has been described with particaularity with reference to preferred embodiments, it will be appreciated, after understanding the invention, that various changes and modifications may be made therein without departing from the scope and spirit of the invention. Accordingly, it is intended to encompass all such changes and modifications as fall within the scope of the appended claims.
