BACKGROUND

1. Field of the Invention

This invention relates to a new and improved single use container. In one respect this invention relates to a single use paperboard and thermoplastic construction container wherein a liquid is aseptically stored and material combinable with the liquid separately stored, and the liquid selectively combined with the material . More particularly, this invention relates to a single use container for the aseptic storage of milk and for the fresh pack storage of cereal, with selectively opening of the container and breaking the aseptic seal to allow the milk to flow onto the cereal. 2. Description of the Related Art

In the field related to aseptic drink containers, it is known to provide a packet of paperboard of plastic film laminate construction for aseptic packaging, with an aperture formed in the top of the packet exposing a thinner area of foil or plastic which the user punctures with the need of a straw. Such constructions are disclosed and discussed in U.S. 4,287,247, issued September 1, 1981 to Reil et al, U.S. 5,303,838, issued April 19, 1994 to Luch et al, and U.S. 4,789,066, issued December 6, 1988 to Lisiecki . In the field related to cereal and milk bowls, it was known to provide a cereal bowl with separate self-contained cereal and milk compartments, as disclosed in U.S. 5,209,348, issued May 11, 1993 to Schafer. The construction disclosed in Schafer is designed to be reusable, and necessarily must be refrigerated in storage prior to use, and then re-washed after use. Schafer provides a valve of complex mechanical design. The Schafer valve extends outwardly from the bowl and can be inadvertently actuated to discharqe the milk onto the cereal prior to the desired use.

The art lacked a single use, commercially practical, disposable, readily and reliably useable cereal and milk container. SUMMARY OF THE INVENTION A single use container for cereal and milk is formed of a first container for aseptically storing a measured supply of milk and a second container for the stay-fresh sealed storage of a measured amount of cereal, with the second container juxtaposed to the first container, and a valve operatively positioned to the first and second containers, so that the user first selectively opens the second container to access the cereal and the valve and then actuates uhe valve by breaking the aseptic seal to allow the milk to gravity flow from the first container onto the cereal in the second container. The valve is protectively disposed in the first container and accessible only from the second container and not accessible until the seal of the second container is broken, thereby avoiding inadvertent breaking of the aseptic seal and concomitant discharge of the milk.

In one embodiment, the valve is a formed of a frangible plastic or metal foil element forming part of the aseptic seal of tne first container, and the second container is formed with an orifice disposed adjacent to the valve so that the milk flows from the first container through the broken frangible element and the orifice into the second container.

In another embodiment, a plastic spoon is designed to be and is positionally disposed within the second container. An end portion of the spoon is specially contoured to permit the user to readily break the frangible seal element

The first and second containers are preferably of rectilinear configuration, with a rectilinear cover or box to hold the first and second containers so as to provide an integral, shelf storable, stackable and displayable single use construction.

In a most preferred embodiment, the first and second containers are of essentially paperboard and thermoplastic laminate construction, and the cover or box of similar construction. The container of the present invention is single use and yet ecologically disposable.

Referring to the FIGS, there is showing the container J O of the present invention. Container 10. is formed of a paperboard box or cover l holding a first paperboard container _. 12 _. for aseptically storing a measured amount of milk 13 _. , a second paperboard container 14 _. for holding a measured supply of cereal 15_, and a metal or thermoplastic

foil top _. 16 _. adhesively sealed to the top edges _. 18 _. of box 1_1 to vacuum seal the cereal in container JL4 _. . A paperboard rectilinear sleeve or spacer 1/7 is provided on which container _. 12. is supportably mounted and in operative disposition to container JL4. B° ^χ -L-L maintains container 12 , container 1_4_ and sleeve 17 in frictional contact . Container 12 may alternatively be thermoplastically sealed or adhesively bonded to container 1_4 to maintain contact, for reasons hereinafter appearing. Container 2_ is formed of generally rectilinear construction and has a top _. 19 _. , sides 2 _. 0, 2JL, _. 22 _. , and 22, and bottom 2_4. Side 2 _. 0 is formed with a recessed orifice 25, disposed adjacent bottom 4. A valve is formed of frangible metal or thermoplastic foil piece 2 _. 6 _. which overlaps orifice 5 _. and is integrally bonded to inside laminate layer 2_7 of container 1 to maintain the aseptic seal, and a tubular plastic member 7 _. 0. Member 7.Q _. is bonded to foil piece 26 , and the walls or sides 2_0 and 3_0 to provide an integral construction. The valve for the aseptic package construction may be constructed as shown and described in

U.S. 5,303,838. Bottom 2-i is provided with a slight central fold on trough 4_9, for purposes hereinafter appearing. Container 1 is of paperboard and thermoplastic or foil laminate construction for the aseptic storage of milk, such is shown and described in U.S. 4,287,247 and U.S. 4,789,066. Container 14. is formed of a paperboard rectilinear construction having sides -2 ---!- HZ, ---2/ and bottom 34. Side 3JD and member 7JD form through hold or orifice 2-2. which

is coincidentally disposed to orifice 2-5 of container 12 for purposes hereafter appearing. As previously mentioned, an adhesive or thermoplastic bond 4_8 may be employed to seal or bond side Q of container 1 to side of container 14. This seal or bond surrounds member _. 70 _. and maintains the integral construction. The paperboard of container 1Λ _. may be thermoplastically lined or coated 36 _. on the inside of container _. 14 _. . A measured amount of dry breakfast cereal, such as flakes 1_5, is contained at the bottom of container 14.. Liner 2- _2. protects the stay fresh condition of the cereal, and the liner 2-i helps contain the milk nd cereal within container 14.

A second valve 2 _/ similar in construction to valve 70 , is disposed in the top 1_9 of container 22- Valve 7J- may, after removal of foil 1_6, be punctured with the end of straw in the well known manner. Valve 7JL may be opened prior to opening valve 1_0_ so that the user may drink some of the milk prior to adding the remainder to the cereal. Valve 21 also serves as an air relief to provide the even flow of milk from valve .70. It is to be born in mind that the invention is operable without valve 1■ and the inclusion of valve 1 is an alternate embodiment.

Box 11 is of paperboard construction and is of rectilinear confirmation having sides 21_, 2JS_, 3_9- 12 and bottom 4_1. The cardboard folded sleeve 17 is positioned in box 11. Container 12 is supportably mounted on sleeve 17. Containers 2 and 14, and sleeve 17 are frictionally held and secured within box H. The foil top piece 16 is releasably

adhesively bonded to contiguous top edge 18 _. of the sides o container 14, by means well known in the packaging art.

Foil piece 16 is provided with lift or pull tab _. 58 _. . The rectilinear folded paperboard construction of units 12, 14 , 1 and H are well known, and such rectilinear boxes or containers are readily constructed by those skilled in the box making art .

A molded thermoplastic spoon 22 is sized and contoured to be removably positioned at its ends 21 and 52 in respective corners 52 and 5_4 of container 4 Spoon 2 is formed with a cylindrical end portion 22 which is sized to be slidable within holes 22 and 2 for reasons hereinafter By means of the aforesaid construction, cereal 1 is vacuum sealed in container J 4, with spoon 2 disposed on the cereal and at the corners of container 14 _. . A measured supply of whole or unprocessed milk 12 is aseptically packaged in container 12.

In operation, the user lifts pull tab 58. of foil piece

16 to break the vacuum seal and pulls or removes the foil piece 16. In this manner, the user then moves spoon 22 through the cereal and inserts end portion 22 through member

70 and holes 22 and 2- _2. to break foil piece 22 With removal of the spoon end 2 the milk 12 gravity flows from container 12 through member and orifices 22 and 22 into container 14 _. and onto cereal 12- Fold 4_9 at the bottom 2± of container 12 ensures that essentially all the milk gravity flows out of container 12.

It is important to note that foil piece 2 β_ is recessed in holes 2-L and so that it cannot be inadvertently damaged or broken, and may only be broken once the user opens container 14 _. and then purposefully inserts the specially designed end 2 of spoon 50.

The box 11, containers 12 and ϋ, and sleeve 17 constructions provide an integral unit which may be stacked and stored on supermarket shelves. Box side 2 by way of example, provides product display information 61. The box ϋ, containers 12 and ϋ and sleeve 17 may be of paperboard or fiberboard construction or like conventional construction, and may be coated and/or impregnated with thermoplastics or waxes, so as to provide semi-rigid, protective packaging. After the user consumes the cereal and milk, the container may be readily ecologically disposed in receptacles designed for waste plastic and paperboard.

It is within the broad contemplation of this invention to provide for all known, and to be invented, forms of milk, such as by way of example, whole, skimmed, low-fat, and the like, and all forms of cereal, such as by way of example, flakes, puffs, granules, and the like. It is also within the broad contemplation of the invention that any liquid and liquid combinable material may be stored and used in the semi-rigid container construction.

The frangible foil construction may be as shown and described in U.S. 5,303,838 and U.S. 4,789,066, as is well known in the art. The valve may be a specially designed

aseptic orifice seal which is first molded and constructed and then thermoplastically bonded to the aseptic container, as is shown and described in U.S. 5,303,838.
