Description
TWO-COMPARTMENT CONTAINER HAVING DEPRESSIBLE FLEXIBLE DOME FOR RUPTURING LAYER BETWEEN
COMPARTMENTS
BACKGROUND OF THE INVENTION
Field of the Invention
This invention relates to packages and containers, and in patticular, pertains to containers having two compartments and that may be used to keep two components separate until use.
Description of the Related Art
Many different types of packages have been designed to enable product components to be kept separate until use and, in some cases, to allow one component to remain sterile until use of the product. In one type of two-compartment package, a stopper or othei means is placed in the hole between the two compartments For example, the two-cornpailment containei of Halm (U S Patent No. 5,417,321) comprises a one-piece containei having two compartments assembled one upon another interlinked by a stoppeied opening. The disclosuie of ail patents refeired to herein is incorpoiated herein by leference.
Other two-compaitment packages utilize a peiforattng unit to allow the two pieviously separated components to mix See, for example, the patents of Goncalves (U.S Patent No 5,170,888 which has a glass defining a first compartment, which is provided with a neck upon which is mounted a bottle defining a second compartment, with a membrane between the two compaitments that is perfoiated when a perforating unit is displaced relative to the glass, and U S. Patent No. 4,757,916 which has two units sepatated by a covei perfoiatable as a result of the manipulation of a mixing perforator). The two-pait container of Wiegner (U.S Patent No. 4,103,772) has a frangible partition of coated aluminum foi! dividing the compartments and a pieicing member mounted on a resilient portion tiansversely directed toward the partition. In the patent of White (U.S. Patent No. 4,637,934) rigid penetrating means are used to penetrate a compartment closing diaphragm to allow nursing liquid to flow fiom the compartment to a communicating, attached nipple. Two compartment packages have also been previously developed which have an opening container attached to the top of the package and are piovided with a screw cap
and a cylinder jacket shaped suppoiting ring The cylinder jacket shaped supporting ring is attached to the top of the package by means of a fixing flange externally sunoυnding the opening disc and is provided on its inner surface with a iaised thread The ring surrounds the external thread of the plastic sciew cap A cutter is integtally molded onto the free edge of the screw cap, and is provided with a Front cutting edge which passes at an angle through the free edge.
For such pioducts as two-part epoxy glues, two compartments are also needed to keep the products from leacting, as in the patent of Wilkinson et al. (U. S Patent No 4,786,279). The dispenser of Renault (U S Patent No 5,564,600) has two compartments sepaiated by a sealing member sealed against a seat, so that movement of one of the containeis lelative to the other causes the sealing membei to move away fiom the seat and form an annular passage between the sealing member and the seat
U.S Patent Nos 6,209,718, 6,105,76O5 6,51 3,650 and 6,786,330 disclose a iwo- compartment package, which keeps a first component separate from a liquid component until use, so that the fiist component does not become wetted until just before use The two-compartment package keeps at least one of the components sterile until just before use, at or befoie which time, the two components may be easily mixed. The prioi invention can thus be used for containers for the separate packaging of dried microbial cultυtes which aie to be added to a food, liquid nutiition, medicine, oi beverage product just before consumption, for the separate packaging of caibonation tablets from a liquid until just befoie consumption, and for separate packaging of vitamins oi other unstable components before addition to a beverage, liquid nutrition, medicine oi beverage before consumption U, S Patent No. 6,098,795 discloses a container and means for adding a selected component to a main package, thus forming a two-compartment container that keeps a fiisi component, which may, for example, be moistuie sensitive, fiom a second component, preferably a liquid, until a selected time before use. The deliveiy package, preferably containing a second component in a compaitment inside a cavity in the delivery package, may be mountable on the outside surface of a main package, A puncture means is provided foi cutting through the compartment and the main package to gain access to the main package, for example, to release the fust component fiom the compaitment into the main package Alternatively, the main package may be a bag, such as an enteral bag in the preferred use of the fust embodiment In the second embodiment of the invention, the main package preferably is for holding a liquid beveiage, and the deliveiy package is attached to the main package during the manufacturing process.
In some cases, such as with aseptically-filled bottles or cartons, there is a need to provide a means foi adding a selected separate first component to a package after manufactuie of the package and/oι at a location on the package, which component may vary in concentration and/or composition, depending, foi example, on the patient's history and diagnosis. Providing a means of attaching a fust compartment to a package after both the fust compartment and package have been manufactured allows a user to select both a patticulai first component to add to a package and the time and place of addition of the first component to the package There is also need to have the capability to add beverage additives, particularly degradable or moisture-sensitive or oxygen- sensitive components (for example, vitamins) to liquid beverage bottles at oi just before the time the beverage is consumed.
The types of structuies used for many prior two-corn paitment containers aie complicated and often subject to leakage Thus, there remains a need to have two- compattmeπt packages which keep a First component separate from a liquid component until use, so that the First component does not become wetted until just before use, that keep at least one of the components sterile until just before use, and in which the two components may be easily mixed just before use, and which has minimal or no leakage prioi to mixing of the components and once the components have been mixed, Foi example, there is a need for such containers fot the separate packaging of diied microbial cultuies which aie to be added to a food, liquid nutrition, medicine, or beverage product just before consumption, for the separate packaging of carbonation tablets fiom a liquid until just befoie consumption, and for sepaiate packaging of for example vitamins, flavoring or coloring agents or othei unstable components before addition to a beveiage, liquid nutrition, medicine or beveiage before consumption. It is therefore an object of the invention to provide a two-compartment container that keeps a First component, which may be moisture sensitive, from a second component, preferably a liquid, until a selected time before use, and that then the separation between the components may be removed without utilizing a puncturing stiuclure.
It is a further object of the invention to provide a two-compartment container that has impioved inanufactui ability and decreased leakage
Other objects and advantages will be more fully appaient fiom the following disclosure and appended claims,
SUMMARY OF THE INVENTION The invention herein is a two-compartment container. The first compartment has an upper layer and a lower layer and contains a first component that is to be added to the
second compartment. Above the fiist compartment is a dome that is bowed upwaid and is flexible Depiessing the dome by pushing downward on it causes the dome to iupture the lower layet of the first compartment, without iupiuiing the upper layer, ieleasing the first component into the second compartment Othei objects and featuies of the inventions will be more fully apparent from the following disclosure and appended claims.

DETAILED DESCRIPTION OF THE INVENTION AND PREFERRED EMBODIMENTS THEREOF
The present invention piovides an impioved two-compaitment containei having a depiessibie dome to release a sensitive component from a first compartment into a second compartment by rupturing a iowet layer between the compaitments, with minimal oi no possibility of leakage As used herein, the lelative directional teims "above", "below" and the like aie used to specify the lelative orientations of the patts of the invention when the container is a bottle, caiton or the like oriented having the opening of the second compartment facing upward. In particular stiuclures or usages of the container of the invention, the container may be oriented in other mannets without departing fiom the invention herein, and it is understood that in such instances, the actual orientation of the paits of the invention are correspondingly changed.
In particular, the invention herein is containei 10 comprising a first compaitment 12 and a second compartment 14 (Figures 1-2) Although generally the second compartment 14 seives as the main compaitment containing second component C2 that is normally a liquid, and the fust compartment 12 serves as a deliveiy package foi a first component Cl to be added to the second compaitment 14, it is understood that by use of the teims "main" package and "delivery" package as used heieiπ, no limitation is placed on the absolute or relative sizes of the packages The teims are used merely to distinguish the two packages by difference in function and sliucluial chaiactei istics, with the main package including packages known in the prior ait for holding substances and the delivery package preferably designed foi holding a first component to be added to the main
package In the prefetred embodiments herein, the second compartment 14 is a screw- capped bottle Oi a carton, such as a juice carton as is known in the art
The first compaitment 12 has an uppei layer 16 and a lowei Iayei 18 and contains a fust component Cl that is to be added to the second compaitment 14 The stiuctuie of the first compartment 12 is pteferably similar to those disclosed in prior patents of the iefeiied to above (see, foi example, U S. Patent Nos 6,098,795; 6,105,760; 6,209,718; and 6,786,330), the disclosure of which is incorpoiated herein by leference. Thus, a pieferred first compartment 12 is pteferably made of foil, and most preferably of foil having a plastic layer on one surface on the outside of the compartment, such as a polyvinyl laminated aluminum foil and with a lacqueied surface on the inside such as OPA lacquer , for example, matei ial nr 31 31781 of ALCAN PACKAGING AG5 (Kreuzlingen Switzerland), Above the first compaitment 12 is a dome 20 that is pait of the cap 24 covering the second compartment 14 and that is bowed upwaid and is flexible Pieferably, the dome 20 is formed of a thin flexible plastic mateiial, as is known in the ait
In the invention herein, collar 36 extending above a threaded area 38 of the cap 24 holds the dome 20 suspended over the second compartment 14 Thus, in use of the invention, depressing the dome 20 by pushing downward on it lowers the dome 20 so that the lower layer 38 of the first compaitment 32, but not uppei layer 16, is i tiptured by pressure of dome 20, releasing the first component Cl into the second compartment 14 Because upper layer 16 is not cut or ruptured, there is not leakage from the outer part due to the movement
In the invention, the first compaitment 12 is bowed upwaid, with the upper layer 16 prefeiably being quite thick, such as being made of a thick plastic and/or foil material The flat lower layer 18 is a thin, easily iupturable foil. Thus, when dome 20 is depressed in this embodiment, it pushes upper Iayei 16 downwaid as shown in Figure 2, so the intact but pushed downward upper layer 16 is pushed against and ultimately ruptures lowet layer 18 as shown, without punctuiing oi rupturing upper layer 16.
In the invention, there is preferably an outer cap 34 over the cap 24, as shown in Figure 1, which prevents accidental depression of the dome 20 pi ior to use, such as during shipping and storage. The foim of this cap 34 may be any known in the ait or as may be useful, and is not a specific part of the invention herein,
The invention is primarily designed for addition of a selected, sensitive fust component Cl, preferably located in first compartment 12, to a liquid located in the main package (second compartment 14) The term "selected" first component Cl as used herein includes fast component(s) chosen foi a particular use, e g., addition to a bottle or
carton to be used by a person requiring additional vitamins or antibiotics, or having a paiticulai volume or concentration, and the like The first component may be a single compound, mixtuie, solution, capsule, tabiet, powder, or any othei containable component(s) to be added to a main package that preferably contains a second component (which may in turn be any containable comρoιmd(s) to which the first component may be added to iesult in a useful pioduct. The ability to select from an assortment of prepackaged first components in the first embodiment herein allows the put chases to puichase and stoie first and second components separately, for example, to keep non- perishable second components at ioom-temperature, and to keep fiist compaitments, each of which has one of any number of assorted first components under appiopriate, possibly separate, storage, for latei addition to the second component. When the first component Cl comprises microorganism cells, the first component is preferably in a powdered formulation as described in the patent applications hereto.
The term "sensitive" includes fiist components which are moisture-sensitive, or which interact with the second component, foi example, by foiming by-products that change the usefulness of the combined components, for example, from initially useful to too weak, due, foi example, to loss oi change of strength oi value with time after the combination of components "Sensitive" first components also include those components that may require special storage and/or handling until just before addition to a second component, for example, refrigeration, desiccation, oi heating; as well as first components that foi any other ιeason(s) are desired to be kept separate from a second component between the time of manufacture and until a later time, such as the time of addition to a second component
It is preferred that the first component be in the form of a powder that is stable when diy and that is easily dissolved oi suspended in the liquid in the main package as disclosed in the parent applications heieto The invention is paidciilatly useful for adding unstable and/oi sterile components to a beverage, liquid enteral nutrition or medicine, for example, adding vitamins or beneficial gastrointestinal microorganisms, such as Lactobacillus reitteri, to fruit juice, milk, water, and medicine While the invention has been desciibed with refeience to specific embodiments, it will be appreciated that numerous variations, modifications, and embodiments are possible, and accordingly , all such variations, modifications, and embodiments are to be regarded as being within the spii it and scope of the invention
