DISPENSING IPAEIIIAGE AND CONTAINIEII 'Ill-IIEIIIEFGIR As evidenced by the prior U.S. Pats. to Rabby et al. No. 3,123,254, Block No. 3,130,875, Zastrow No. 3,246,825 and Carlson No. 3,338,403, it is well known in the prior art to provide various types of receptacles for the packaging, storage or transport of liquid containers. In Carlson, for example, the package includes a pair of containers arranged end to end to permit transfer of the contents of one container to the other. It is also known in the prior art to provide packages in which fluids from two compartments or containers are mixed prior to discharge, as evidenced, for example, by the US. Fat to Flynn No. 3,079,044.
In recent years, a demand has been made for a relatively inexpensive disposable package for dispensing products from a nonrefillable container, such as an aerosol can or similar pressurized container. Furthermore, the need has arisen for a lightweight carton that may be readily carried by one hand, the other hand of the user being free to direct spray means for the fluid dispensed from the container. In order to actuate the discharge valve means associated with the container, discharge operator means are required that are operable by one hand of the user, preferably the one by which the package is being carried. Moreover, in accordance with another recent development in the art, fluids dispensed from a plurality of containers are designed to chemically or physically react with each other to produce a desired end product or reaction. For example, in apparatus developed to produce a rigid urethane foam for use in caulking openings, for sealing cracks and the like, measured quantities of different pressure fluids are dispensed simultaneously from a pair of containers and are mixed to produce a high quality froth foam the ingredients of which react to form a rigid product. The present invention was developed to meet the above and similar additional packaging requirements.
The primary object of the present invention is to provide a lightweight portable carton adapted for use in the housing, transporting and simultaneous dispensing of pressure fluids from a plurality of containers. The carton is of a rectangular configuration formed from a blank of cardboard, paperboard, foil laminate, or the like, said carton including support means for supporting the receptacles in side-by-side relation within, and spaced from the ends of, the carton.
A more specific object of the invention is to provide a light weight carton of the type described above, characterized by the provision of improved handle means adjacent the top of the carton that serve not only for the manual transport of the dispenser package when in a vertical orientation, but also as part of the support means for preventing upward movement of the containers relative to the carton. In one embodiment of the invention, valve operator means are provided including an actuator member arranged adjacent the handle means for operating the valve means of a plurality of containers to simultaneously discharge a plurality of pressure fluids therefrom, whereby a user with one hand may both transport the package and dispense a mixed fluid therefrom. The handle means may either be formed as an opening in the upper portion of one sidewall of the carton, or as an opening in a central divider flap that extends transversely across the upper portion of the carton.
A further object of the invention is to provide a dispensing carton having improved support means for supporting the containers in side-by-side relation intermediate the ends of the carton. In one embodiment, the receptacles have annular flanges adjacent their lower ends that rest on vertical support flaps which extend upwardly within the carton from the lower edges thereof. In a second embodiment, the receptacles are further supported at their lower ends by an additional horizontal support panel that in turn is supported by the upper edges of the aforementioned support flaps.
Other objects and advantages of the invention will become following specification when conin which:

FIGS. Ill-I3 are views of the body, bottom and top handle blanks used in forming the carton of FIG. 8.
Referring first more particularly to FIGS. 1-4 the portable dispensing apparatus includes a lightweight cardboard container 2 in which are mounted a pair of receptacles 4,6 provided at their lower ends with dispensing valves 8 and I0, respectively. In the illustrated embodiment, both of the receptacles comprise aerosol cans the dispensing valves of which include hollow stem members I2 and 14 that are displaceable angularly to discharge fluid under pressure from the cans. Connected at one end with the valve stems I2 and I4 are a pair of flexible conduits I6 and 18, respectively, said conduits being in communication at their other ends with a mixing chamber 20 contained in the cylindrical body 22 of mixing and spray valve means 23, said body having a discharge opening 24.
Referring now to FIGS. 5 and 6, the container is formed from a first blank 26 and a separate panel or blank 28 each formed of cardboard, paperboard, a foil laminate, or the like, the first blank including a series of rectangular sections connected along vertical hinge lines to define, in succession, a first sidewall section 30, a first end wall section 32, a second sidewall section 34, a second end wall section 36, and a third sidewall section 38. Hingedly connected with the lower edges of walls 30, 32, 34 and 36 are support flaps 30a, 32a, 34a and 36a, respectively, said support flaps having the same vertical dimension and being foldable upwardly into engagement with the inner surfaces of the corresponding wall sections toward the vertical receptacle-supporting positions shown in FIG. 7. ll-Iingedly connected with the upper end of first sidewall 30 is a handle flap 30b, said first sidewall 30 and said third sidewall 38 containing adjacent their upper edges identical handle openings 40, 42, and said second sidewall 34 containing adjacent its upper edge a circular nozzle storage aperture 44. The second sidewall 34 also contains adjacent its lower edge an opening 46 that extends partially into flap 34a to define a retainer slot 48 when the support flap 34a is folded upwardly toward the vertical receptacle-supporting position shown in FIG. 7.
The second cardboard blank 28 has a width substantially equal to that of the sidewalls 30, 34 and 38, said second blank including a central section 50 containing an aperture 52, a handle section 543 containing a handle opening 56, and a third section 58 containing a circular nozzle-receiving aperture 60. The width of the central section 50 is generally equal to that of the end wall sections 32 and 36.
Referring again to FIGS. 2 and 4, in accordance with an important feature of the present invention, operator means 68 are provided for simultaneously operating the valve stems I2 and I4 to dispense fluids under pressure-from aerosol cans 4 and 6 into mixing chamber 20 via conduits l6 and I8, respectively. The operator means 68 includes at its lower end a pair of annular member 70, 72 mounted on the stems I2 and 14, respectively, and connected at its upper end by means of an intermediate portion 73 with a trigger ring 74 adjacent the handle opening. To prevent inadvertent operation, the valve stems are normally provided with removable semicircular lock members 75 and 76, respectively, as shown in FIGS. 2.
Referring now to FIG. 7, to assemble the apparatus of FIGS. 1-4, the blank 26 is folded into a rectangular configuration with the sidewall 38 adjacent the inner surface of sidewall 30, and the lower support flaps are folded upwardly to the vertical positions. The valve operator means 68 are connected with the handle blank 28, whereupon the containers 4 and 6, the valve operating means 68 and the handle blank 28 are inserted within the carton, the containers being supported at their lower ends by the cooperation between annular flanges 4a and 6a and the upper extremities of the support flaps 30a, 32a, 34a, and 36a. The vertical flaps of the handle blank are then secured to the corresponding carton sidewalls, and the tab 30b is folded downwardly upon and is secured to the section 54 as shown in FIG. 4. Consequently, owing to the support of the containers afforded by the horizontal panel 50 and the support flaps 3011, 320, 34aand 360, the containers are restrained against vertical movement relative to the carton.
Referring again to FIG. 2, it will be seen that with one hand, the user of the dispensing apparatus may engage both the carrying handle and the trigger ring 74 of the dispenser operator means 68, and with the other hand may direct the mixing and spray nozzle means 23 in any desired direction relative to the carton. Following removal of the valve lock means 74 and 76 (shown in FIG. 4), the dispenser operator means 68 may be actuated to dispense fluids from receptacles 4 and 6 into mixing chamber 20, whereupon the resultant mixture is discharged through discharge opening 24.
Upon release of the operator means 68, valve means 8 and are closed to interrupt discharge of fluid from receptacles 4 and 6, whereupon flexible conduits 16 and 18 are inserted into retainer slot 48, and nozzle 23 is inserted into the storage aperture 44 as shown in FIG. 1. If desired, lock means 75 and 76 may be replaced upon valve stems 12 and 14, respectively, to prevent inadvertent operation of the dispenser means.
Although the handle and upper support sections 50, 54 and 58 have been illustrated as being formed as sections of a separate blank 28, it is apparent that, if desired, these sections could be hingedly connected with the upper edges of either of the sidewalls 34 or 38.
Referring now to FIGS. 8-13, a second carton embodiment is disclosed that is adapted to house and transport a pair of pressure fluid containers 80 and 82 that are appreciably larger and heavier than the aerosol can type containers 4 and 6 of FIG. 2. To this end, the means for supporting the containers at their upper and lower ends are greatly strengthened to provide a more rugged and durable carton construction. As shown, more particularly in FIG. 9, at the lower end of the carton 84, auxiliary lower support means 86 are provided that are mounted upon the vertical support flaps hingedly connected with the lower edges of the carton walls. At the upper end of the carton, improved and strengthened handle and upper support means 88 are provided as shown in FIG. 10.
Referring now more particularly to FIG. 11, the carton blank includes, in succession, a locking wall 90, a first end wall 92, a first sidewall 94, a second end wall 96 and a second sidewall 98, said walls being vertical and hingedly connected for folding to the vertical rectangular carton configuration of FIGS. 8-10. Support flaps 92a, 94a, 96a and 98a are hingedly connected with the lower extremities of the walls by the intermediate panels 92b, 94b, 96b and 98b. Connected with the upper edges of sidewalls 92 and 96 by the intermediate horizontal panels 92d and 96d are locking flaps 92c and 96c having at each vertical edge locking tabs 92c and 96:2, respectively. The sidewall 94 contains a pair of access openings 102, and the support flap 94a contains corresponding access slots 104, whereby access is provided to the discharge valve means 800 and 820 at the lower ends of the containers 80 and 82 as will be described below.
The lower support blank 86 includes successive hingedly connected section 110, 112, 114, 116, 118 and 120, said blank being foldable in half about hinge line 122, and then into the U-shaped configuration of FIG. 9, whereupon sections 110 and 120, 112 and 118, and 114 and 116 are contiguous, respectively, sections 112 and 118 containing aligned openings 124 for receiving the valve means a and 82a when the containers are supported thereon, and sections 114 and 116 containing aligned openings 126 for arrangement opposite the wall openings 102 and the flap access slots 104.
The upper handle blank 88 includes, as shown in FIG. 12, successive hingedly connected sections 140, 142, 144, 146, 148, 150, 152 and 154, securing flaps 146a and 148a being hingedly connected with the lateral edges of sections 146 and 148, respectively. Sections 144, 146, 148 and 150 containing handle openings 158 so arranged that when the blank is folded about center edge 147 and then sections 142 and 152 are folded to the horizontal container supporting positions of FIG. 10, the handle openings are in alignment. Furthermore, openings 160 contained in the handle sections 144, 146, 148 and 150 define slots in the upper edges of the handle means 88 when in the folded condition of FIG. 10.
To assemble the carton of FIGS. 8 10, the sections 90, 92, 94, 96 and 98 are folded to the illustrated rectangular configuration, and containers 80 and 82 (with the corrugated cardboard spacer means therebetween) are inserted in parallel side-by-side relation within the carton. The bottom support blank 86 is folded to the generally U-shaped configuration of FIG. 9, and is inserted within the lower portion of the carton with the container valve means 80a and 82a being received by the aligned openings 124. The support flaps 92a, 94a, 96a and 98a are then foldable upwardly to the vertical support positions with the horizontal support panels 112 and 118 of blank 86 being supported by the upper edges of the vertical support flaps, and the vertical sections 110 and 120 and 114 and 116 being contained between the support flaps 98a and 94a and the corresponding carton sidewalls. At the upper end, the handle blank 88 is folded and inserted within the canon as shown in FIG. 10, the handle flaps 146a and 1480 being folded outwardly against the inner surfaces of the end walls 92 and 96. The locking flaps are then folded downwardly with the sections 92d and 96darranged in horizontal engagement with the upper surfaces of the central handle sections, the vertical flaps 92c being inserted downwardly with the slots 92f and 96f in locking cooperation with the handle slots 160. Locking tabs 92c and 96e are secured (by stapling, adhesive means, or the like) to the corresponding carton sidewalls to complete the carton assembly.
To use the apparatus of FIGS. 8-13, the flexible conduits 180, 182 of the mixing nozzle means 184 are inserted through the openings 102, 126 and 124 for connection with the manually operable valve means 80aand 820. Following openings of the valve means, the user may transport the apparatus with one hand by the handle means 86, and with the other hand may dispense the pressure fluid mixture via the mixing and and dispensing nozzle means 184.
In the illustrated invention, the containers contain pressure fluids that, when mixed, react to produce a foamed product. For example, in the case of polyurethane foam, one container may contain pressurized polymeric isocyanate adapted for reaction with an amine and fluorocarbon-containing polyol pressure fluid in the other container.
While in accordance with the provisions of the Patent Statutes, the preferred form and embodiment of the invention has been illustrated and described, it will be apparent to those skilled in the art that various changes and modifications may be made in the apparatus described without deviating from the inventive concept.
