Abstract

ABSTRACT OF THE DISCLOSURE

A container providing for the separate storage of two materials and the admixing of the materials upon opening of the container. A main container holds a quantity of a first material, such as car-bonated water, and a separate compartment holds a small quantity of a second material, such as a dipeptide sweetener flavoring. The disclosure provides several embodiments of the invention where-in a bottle has a compartmented closure applied as a cap thereto. The closure incorporates a compart-ment, which may be substantially cylindrically shaped, for the second material, and has a flexible top wall and a releasable bottom wall which is positioned within the neck of the bottle. An actuat-ing rod extends through the compartment intermediate the flexible top wall to the releasable bottom wall whereby, when it is desired to admix the first and second materials, the flexible top wall is pressed down to force the actuating rod against the releas-able bottom wall, thereby causing it to pivot open and release the second material within the compart-ment to admix with the first material in the bottle.

Description

~1~2951 CONTAINER HAVING SEP~RATE STORAGE
FACILITIES FOR TWO MATERIALS

BACKGROUND OF THE INVENTION
- Field of the Invention The present invention relates, in general, to containers and, more particularly, pertains to containers having separate compartments in which several ingredients of a product may be stored separately until it is desired to admix them, at which time it is possible to establish communication between the compartments so that the separated ~: ingredients may be admixed prior to dispensing of the product from the containers.
~; Containers of this type are useful for the separate storage of ingredients or materials for a ~, variety of products, and have particular applic-ability to the fields of pharmaceuticals and cosmetics, for instance, where at least two ingred-ients can be stored separately for reasonably - 20 lengthy periods of time, but if admixed will produce a product which deteriorates rather rapidly. Such products usually, but not necessarily, comprise at least one liquid ingredient and one other ingredient ` which may be either in the form of a liquid or in ~, 25 the form of dry granules or powder.
~` Other fields of application in whic~ such ~ containers may find utility are in the separate 'x .~ . . . . . .

~ Another important field of use for containers - of this type lies in the storage of foodstuffs and particularly beverages. Thus, a new flavoring constituted of dry ingredients, and being in the form of granular material or a powder may have been developed for carbonated beverages which has signi-ficant potential consumer appeal in comparison with existing products, with the beverage, however, having a limited shelf life after the flavoring is mixed with liquid or carbonated water present in the container. The flavoring has a lengthier shelf life when maintained in a dry condition and separate from , ~20 the water or liquid, and with the product being more flavorful and marketable when stored in a container which maintains the flavoripg and carbonated water in separate compartments and inaccessible to each other until opening of the container for the purpose of dispensing the beverage.
Discussion of thé Prior Art At present, the prior art discloses various containers or receptacles for the separate storage of various materials or ingredients of a product adapted to be admixed prior to dispensing from the containers.

Moreover in the disclosed embodiment, the actuating rod is integrally formed with or connected to the releas-able compartment wall. Furthermore, the disclosed embodiment provides structure in which the closure is formed of inner and-outer members, with the inner member comprising the releasable wall, the actuating rod and the cylindrical side walls of the compart-ment extending over the lip of the bottle neck, and with the outer member comprising the top flexible wall and bottle neck-engaging flange of the closure.
In another embodiment of the invention, there is disclosed an arrangement wherein a container for storing a first material, preferably in the shape of a cylindrical can, has a top closure surface with a pull-top opener attached to the latter. A compart-ment for sèparately storing a second material is attached to the top closure interiorly of the con-tainer and is operatively connected to the pull-top opener. Upon opening of the container by means of the pull-top opener, the compartment tilts downward to dispense the second material in the compartment into the container and admix with the first material.
Moreover, in the disclosed embodiment of the inven-~ion, the container is a can of which the top closure forms one wall surface of the compartment.
Furthermore, the compartment is coupled to the pull-top opener in a manner so that upward pull on , . - :

D~'l'AIL~ CRlP'l`lON Ol~ AWlNCS
Referring now in detail to the drawings, in Figure 1 there is illustrated a first embodiment of the invention wherein a container 10 in the shape of a bottle has a bottle cap closure 14 applied to the top of its neck 12. The container may be a standard commercial bottle formed of glass or plastic, and is adapted to hold a first material 16 therein, prefer-ably a liquid such as carbonated water. The closure14 has a substantially cylindrically shaped compart-ment located therein which contains a second material 18. The second material 18 may be flavoring for the carbonated water, such as a dipeptide sweetener in either granular or pulverulent form. It is desir-able to separately store the dipeptide sweetener from the carbonated water since the dipeptide sweet-ener undergoes a hydrolysis reaction after being admixed w~ith water, which imparts a limited shelf life to the mixture after admixing thereof. The closure 14 is formed of an outer member 20 which has a flexible or resiliently deformable top surface or crown and substantially cylindrically shaped side walls of flange which closely covers an inner compartment-forming~member 22 which has an obliquely sloped bottom wall surface and substantially cylindrically shaped side walls. The outer member 20 may be formed of any flexible or resiliently yieldable material such !as plastic or a thin metal.
The inner member 22 includes a flange portion 24 -: .

~' ' ' ''' . ' ' ~ . ' - :

~SZ951 which ex~en(ls over a beaded lip 26 fornled at Lhe top of the bottle neck 12 to securely fasten the closure 14 to the bottle. A first portion of the compart-ment con~aining the second material 18 extends into the neck 12 of the bottle in the form of a sleeve 28 in close contact with the inner wall surface of the bottle neck, while a second sleeve-like portion 30 of the compartment projects above the neck of the-bottle into engagement with the inner surface of the cap crown. In modifications of this embodiment of the invention, the compartment might extend to a greater or lesser degree into the neck of the bottle. The sloped bottom wall 32 of the compart-ment is formed with a weakened annular wall section 34 extending almost entirely around its entire circumference proximate its attachment to sleeve 28 with the exception of a small tab portion 36 which is constituted of a slightly heavier thickness than the weakened wall portion. The bottom wall 32 of the compartment has an actuating rod 38 connected thereto or integrally formed therewith which extends j generally vertically upwardly through the compart-: ment to the upper end thereof into contact with the lower or inner crown surface of the outer member 20.
The inner member 22 may be formed of various types ` of materials and, preferably, is formed of molded plastic. The outer member 20 fits snugly over the - inner member 22 in the region extending over the bottle lip 26 so as to form a pressure-tight seal structure.
The arrangement is such that a consumer may press down on the top surface of the closure cap crown in the direction of arrow A, thereby causing the top surface to deflect downwardly and, result-ingly, displace the actuating rod 38 downwardly in .

~1~5Z951 conjunction with the bottom wall 32 of the coml>ar~-ment. The force is sufficient to cause severance of the bottorn wall 32 from sleeve portion 28 along its ,annu'lar wcakened wall section 34 thereby opening the cornpartment and allowing the second material 18 in the compartment to empty into the first material 16 in the container 10. The tab portion 36 prevents '~ the bottom wall 32 from completely separating from the remainder of the inner member 22 and falling into the container. The force exerted against the flexible top surface is also adequate to contain any added pressure acting against the top wall which may be encountered by the release of pressurized gas - from the container into the compartment.
Figures 3, 5 and 5 illustrate a second embodi-ment of the invention in the shape of a wide-mouth jar or bottle 40 which, as in the previous instance, may be formed of glass or plastic. A peel- or pry-off closure 42 includes an outer portiorl 44 and an inner portion 46. The outer portion 44 includes a flexible or resiliently yieldable top wall 48 and a flanged rim section 50 which curves down and about in close engagement with the lip 52 of the container so as to seal the closure to the container. The outer portion 44 may be formed of a relatively soft flexible or pliable material such as aluminum foil which will permit its removal from the container without the need for an opener. The inner portion 46 includes a generally cylindrical side wall 54, the upper portion 56 of which curves upwardly and outwardly over the lip 52 of the container and below the flanged rim section 50 to form a pressure-tight - seal between the top of the bottle 40 and the outer member 44. The inner portion 46 also includes a releasable bottom wall 58, as shown ,in enlarged .

de~ail in ~igure 4 of the drawings. Wall 58 is hinge~ at one edge 60 to the cylindrical side wall 54 at the lower end thereof, as shown in Figure 5.
Bottom wall 58 fits into an annular recess 62 formed in the bottom of the side wall, and may be held in that position closing the compartment by either being force-fitted into recess 62 or, alternatively, held in place by a suitable adhesive. The inner portion 46 also includes an actuating rod 64 which is connected to or formed integrally with the releasable bottom wall 58 and which extends upwardly through and centrally of the compartment into con-tact with the lower surface at the center of the flexible top wall or bottle cover 48.
When a consumer wishes to use the contents of ; the apparatus, the consumer presses down on the center of the top cover wall 48, in the direction of arrow A, thereby flexing the wall downwardly and, resultingly, concurrently downwardly displacing the actuating rod 64, thereby causing the bottom wall 58 to pivot downwardly, as shown in Figure 5, about hinge 60 integrally joining it to side wall 54, and to release the contents of the compartment into the container and admix with the contents of the latter.
After the contents of the compartment have been released into the container, the entire closure, 'L including the inner and outer portions thereof, may `~- be peeled off the top of the container and removed as indicated by the phantom lines in Figure 5. If it is desired to reclose the bottle, the bottom wall 58 together with actuator rod 64 may be detached from the closure structure, i.e. by twisting off a hinge 60, and discarded. The remaining closure structure can then be readily snapped onto the lip ' ~ 35 of the bottle.

The con~ainer 70 is the sanle ~ype of wide~ ouLh jar or ~otLle, sui~ably formed of g1ass or plasLic, how-ever, the closure 72 is formed somewhat differently.
lhe outer closure portion 74 now comprises an annular rolled flange sealing member 76 which extends about and over a lip 78 formed at the tOp or orifice of the bottle. The function of the outer portion 74, in this embodiment, is primarily to seal the closure to the bottle.
The outer portion-may be formed of various types of materials, with a suitable material being a soft metal, such as aluminum or aluminum foil. The inner closure portion 80 includes structure for forming the complete compartment, including a flexible or resiliently yieldable top wall 82, an annular or toroidal flanged sealing portion 84 which extends below the annular outer portion 74 so as to complete the seal with the lip 78 of the bottle 70.
A cylindrical side wall 86 which is integrally formed with portion 80 extends into the neck portion of the bottle in proximity to the inner wall thereof. An actuating rod 88 is formed integrally with the center of the top wall portion 82 and depends down-wardly therefrom into contact with a horizontal bottom wall 90. A flexible hinge 92 connects one edge portion of bottom wall 90 to the lower end of side wall 86 in a manner adapted to form a closed compartment, in effect, either force-fitted into a recess provided in the bottom of the side wall 86, or adhesively fastened thereto. Inner member 74 may be formed of various materials, with one suitable construction being of molded plastic. In one .

~;2951 a]ternative ~lodification of this embodimen-, the releasable bottom wall 90 may be formed of a thin rupturable film, such as aluminum foil, which will , rca~ily rup~ure upon ~orce being applie(l Lhere~o by ,thc actuating ro~ 88. The embodioen~ of the inven-tion shown in Figure 6 provides for an arrangement which operates in much ~he same manner as ~ha~
'` illustrated in Figures 3 to 5 of the drawings.
The embod,iments of the invention described,thus far have a number of advantages over known prior art constructions. Thus, the closure is of a simple construction which may be easily formed or molded from two pieces of material. The compartment in the closure may be readil~ filled with a product ingred-ient, and the compartmen$ sealed by interfitting thetwo segments of the closure prior to the latter being mounted on the container. If the container holds carbonated water, the initial depression of the closure top surface so as to open the compart-ment and release its content into the containerconfines the release of carbon dioxide which occurs upon occasion when a carbonated beverage container is opened. The entire closure may be removed from ,!
the container without leaving behind any remnants or residue in the container. Further~ the contents of the compartment are released into the container past the neck of the container whereby, if the container is imbibed from directly, no residue of the second material is found around the opening or bottle orifice which,will be directly contacted by the lips. Moreover, the closure is a type which may be '' reapplied so as to reseal the container.

A small depression 114 for~ d in ,' the top of the càn closure 102 allows a consumer convenient gripping access to a pull-tab 116 on the opener 112 when it is desired to open the container, and an aperture 118 in the opener which permits the consumer to firmly grasp the opener. 'rhe opener 112 extends over and seals-off a round-cornered rec-tangular access aperture 120 formed in the top closure 102 of the can. The body and/or closures of the can may be formed of any suitable material, such as aluminum or steel. A compartment in the form of a cup 122 is filled with an ingredient 124 adapted to be ev~ntually admixed with the contents of the ,20 can, and the cup 122 is fastened, as by a releasable glue, along its rim portion to the inner wall sur-face of opener 112 facing the can top closure 102.
Thc area defined by the side walls of the cup is smaller than the aperture 120 formed in the top closure 102 of the can above the location of the cup and, accordingly, the main portion of the cup is held in place only by adherence to the surface of the opener 112, a flange portion 128 and a handle section 130 on the cup upper rim preventing movement out of the aperture 120. The handle section 130 of the cup is attached directly to the inner surface of the top closure of the can and not to the opener.

from adherence to the opener 112. Upon release of the cup, the cup is biased down, as shown by the phantom lines in ~igure 7, to assume a downwardly inclined position in which its contents are released into the container so as to admix with the contents in the latter. The top closure 102 of the can is also provided with a small pressure release aperture 134 which allows pressurized gas in the can to be vented preceding the opening of the access aperture 120 and release of the contents of cup 122. The pressure release aperture 134 is normally covered and sealed by the pull-tab opener 112. As the opener 112 is pulled off, the pressure release aperture 134 is vented prior to opening of the access aperture 120, which allows any excess pres-sure in the container to be released prior to open-ing of accéss aperture 120. This feature prevents vented gas from the container from entraining material contained in the cup 122 from being blown out of the container. The top closure 102 and opener 112 may be formed of metal, with aluminum being particularly suitable, and the cup 122 may be constituted of plastic. The embodiment of the invention shown in Figures 7 and 8 has a number of advantages over known prior art constructions, including the following: The top of the can may be relatively easily manufactured from three pieces;
the top closure, the pull-top opener and the cup.
The cùp may be filled prior to being assembled with the top closure and the three-piece assembly may then be easily applied to a standard can body.

The vent aperture provides for the venting of any excess gas pressure present in the can prior to opening of the can. Furthermore, after opening of the container, no loose debris remains in the can;
Although several embodiments of the invention have been described herein in detail, the teachings of the present invention will suggest many other embodiments to those skilled in the art. For instance, although only two separately stored ingredients for a product are shown and described in the disclosed embodiments, it should be apparent to one skilled in the art that embodiments fall within the scope of the invention wherein three or more materials may be separately stored and automatically admixed upon or preceding opening of the container.
Furthermore, although several types of convenience openers for the containers have been illustrated, other types of openers may be used in other embodi-ments or modifications of the invention.
