The present invention relates generally to the field of container constructions.
Many nutritive substances which would be beneficial if included in food or drink products are sensitive to heat, light, oxygen, and/or moisture. For example, a nutritive substance which is sensitive to heat cannot be added to a food or drink product that requires heat sterilization because the high sterilization temperatures may damage or destroy the nutritive substance. As a result of these limitations, containers have been developed that can separate the nutritive substance from the food or drink product prior to consumption. The user can then dispense the nutritive substances into the food or drink product just before consumption. The present invention, therefore, relates to a container which can separately contain a nutritive substance and a food or drink product and deliver the nutritive substance to the food or drink product just before consumption.
In an embodiment, the invention comprises a novel apparatus for delivering a nutritive substance comprising a container body having a base at one end thereof, an upper portion adapted for removable receipt of a closure, the upper portion defining an opening therein, and a chamber defined by the container body, the chamber being in fluid communication with the upper portion opening. A laminate seal having at least two layers is bonded across the upper portion opening and is adapted to provide an airtight seal across the opening and prevent contact between said nutritive substance and the contents of said container until said seal is altered. The laminate seal comprises a first layer permanently bonded to a rim defining the opening in the container upper portion and a second layer that is releasably coupled to the first layer. A nutritive substance is bonded to the first layer of the laminate seal. The container additionally comprises a closure removably coupled to the upper portion.
In another embodiment, the invention is directed to an apparatus for delivering a nutritive substance comprising a container body having a base at one end thereof, an upper portion adapted for removable receipt of a closure, said upper portion defining an opening therein, and a chamber defined by said container body, the chamber being in fluid communication with the upper portion opening. The invention also comprises a laminate seal having at least three layers, the laminate seal being bonded across the upper portion opening and adapted to provide an airtight seal across the opening, wherein a centrally-positioned layer of the laminate seal comprises a nutritive substance and wherein the laminate seal prevents contact between the nutritive substance and the contents of the container until said seal is altered. Additionally, the invention comprises a closure removably coupled to said upper portion.
In another embodiment, the invention is directed to a method for making a delivery apparatus, said method comprising the steps of providing a container body having a base at one end thereof, an upper portion at the other end of said body, wherein said upper portion is adapted for removable receipt of a closure, said upper portion defining an opening therein, a chamber defined by said container body, said chamber being in fluid communication with said body upper portion opening, and a closure adapted to be removably received on said upper portion; filling said container with a product; sterilizing the product-filled container; sealing said container upper portion with a laminate seal, said laminate seal having at least two layers, wherein a first layer of said laminate seal is bonded to a rim of said container, a second layer of said laminate seal is removably bonded to said first layer, and a nutritive substance is bonded to said first layer; and placing said closure on said body upper portion, wherein said seal prevents said nutritive substance from contacting said product and the atmosphere surrounding said container until the seal is altered.
A full and enabling disclosure of the present invention, including the best mode thereof directed to one of ordinary skill in the art, is set forth in the specification, which refers to the appended figures, in which:
Repeat use of reference characters in the present specification and drawings is intended to represent same or analogous features or elements of the invention.
One of ordinary skill in the art will understand that the present discussion is a description of exemplary embodiments only, and is not intended as limiting the broader aspects of the present invention, which broader aspects are embodied in the exemplary construction. A repeat use of reference characters in the present specification and drawings represents the same or analogous features or elements of the invention.
As set forth above, the present invention relates generally to the field of container constructions. References related to container constructions may include U.S. Pat. Nos. 5,707,353 and 5,921,955 to Mazer, et al. and U.S. Pat. No. 6,098,795 to Molistam, et al.
The technical problem to be solved by the present invention is to provide novel containers that are useful in delivering a nutritive substance to the contents of a container just before consumption of the contents. Thus, in an embodiment, the present invention is directed to a container having a nutritive substance disposed between at least two layers of a laminate seal. Before consumption of the contents of the container, the laminate seal may be pierced or altered such that the nutritive substance is released into the contents of the container. In other embodiments, the nutritive substance may be present on an insert or may be coated onto the interior of the container such that it does not contact the contents of the container until the container is altered by the consumer just before consumption.
With reference now to the drawings, and in particular to
Referring particularly to
In an embodiment, closure 16 includes an annular cap 28 having a helical thread (not shown) on its inner circumference for operatively engaging threaded cylindrical top portion 18. The outer circumference of annular cap 28 may contain ribs or knurling 32 to allow the user to more easily grip closure 16 to remove it from, or fit it on, top portion 12. In addition to its internally threaded cylindrical wall, cap 28 may include an annular end wall 34 having an extension 36 defining a though hole (not shown) therein. A second annular enclosure 38, having an opening 40 formed therein, may be operatively secured to annular end wall extension 36 so that second annular enclosure 38 is moveable between a first position where second annular enclosure 38 prevents the contents of the container from flowing through opening 40 and a second position where the contents of the container are able to flow through opening 40. It should be understood that closure 16 may be formed from any type of closure known in the art.
With reference to
Second layer 48 may be permanently bonded to rim 20, while first layer 46 may be releasably bonded to rim 20, second layer 48, or third layer 52 so that when first layer 46 is removed, second layer 48 and third layer 52 remain bonded to rim 20 (shown in
In a particular embodiment, first layer 46 is releasably bonded to second layer 48 such that third layer 52, disposed between first layer 46 and second layer 48, cannot contact the container content until first layer 46 is removed. In this embodiment, the second layer hole 50 may be slightly smaller than the third layer hole 54. This configuration allows first layer 46 to bond directly to second layer 48 at the rim of the container and at the hole 50, sealing third layer 52 between the first and second layers.
Referring to
In other embodiments, releasable seal 42 comprises two layers: a first layer 46 and a second layer 48. The first layer may comprise a tab 44 which may be bonded or integrally formed therewith. The second layer 48 may define at least one hole 50 therethrough. A nutritive substance may be bonded to the upper side of second layer 48, disposed between first layer 46 and second layer 48. Second layer 48 may be permanently bonded to rim 20, while first layer 46 may be releasably bonded to second layer 48 so that when first layer 46 is removed, second layer 48 remains bonded to rim 20. In use, tab 44 may be gripped and pulled away from rim 20 causing the bond to fail between releasable seal first and second layers 46 and 48 and exposing nutritive substance to the atmosphere. Closure 16 may then be replaced on threaded cylindrical portion 18 thereby resealing the container. When closure 16 replaced onto the container, each time the consumer inverts the container, the contents of the container flow from the container through aperture 22 and hole 50 into contact with the nutritive substance, providing a gradual release of the nutritive substance prior to or during consumption.

If the user pulls annular cap 224 upward, annular cap inwardly pointing flange 226 moves over flange 246 and is prevented further upward movement when it contacts vertical wall outwardly pointing flange 222. In this position, each time the consumer inverts the container, the contents of the container flow from the container through hole 248 into contact with the nutritive substance layer, which provides a gradual release of the nutritive substance during consumption of the product. Similar to the previously described embodiment, the configuration of seal 240 protects the nutritive substance from exposure to the atmosphere and the contents of the container prior to piercing of the seal, thereby extending the shelf life of the nutritive substance. In this embodiment, seal 240 provides a seal on container 212 and provides a vehicle for carrying the nutritive substance.
It should be understood that a tear band is not required in this embodiment. Any device which prevents spike 236 from contacting releasable seal 240 until just before consumption of the product may be utilized in this embodiment.

Closure 316 may include an annular cap 328 having a helical thread 329 (
With reference to
An insert 352, which is coated with a nutritive substance, may be snap-fitted inside annular end wall extension 336 or may be secured in place by any other suitable method. In the alternative, a nutritive substance may be coated directly on the inside surface of annular end wall extension 336 or any other portion of the annular cap 328 or closure 316 that contacts the contents of the container upon consumption. In yet another embodiment, insert 352 may be secured within annular end wall extension 336 and a nutritive substance may be coated directly on the inside surface of annular wall extension 336. If utilized, insert 352 may be placed within the closure just prior to the capping procedure down stream from the filling/sealing procedure so that the nutritive substance is exposed to the atmosphere for only a limited period of time. The use of an insert may allow for standard closures to be retrofitted with the inserts without the need to redesign the closure.
In use, a consumer may remove closure 316 to reveal releasable seal 342. As the releasable seal tab is pulled away from rim 320, the tensile force applied on the bond between releasable seal 342 and rim 320 causes the bond to fail, thereby allowing the user to remove the releasable seal. In the arrangement shown in

Threaded cylindrical body 418 is adapted to threadably receive a removable cover 416. An inner circumference of threaded cylindrical body 418 may be coated with a nutritive substance layer 430 on the surface above the connection of circular seal base 428 and threaded cylindrical body 418. It should be understood by those in the art that nutritive substance layer 430 may take various forms so long as the nutritive substance is maintained in place above closure circular seal base 428. Thus, an insert having a nutritive substance coating may be press fitted into the inner circumference of threaded cylindrical body 418.
Cylindrical top portion 418 and body 412 may be integrally molded of a suitable polymer material, which may be blow molded, by extrusion or injection, so that it is a unitary member of uniform wall thickness. Suitable polymers for forming the container include, but are not limited to, polystyrene, polystyrene-acrylonitile, acrylonitile-butadiene-styrene, styrene-maleicanhydride, polycarbonate, polyethylene terephthalate, polyvinylcyclohexane, and blends thereof. In the alternative, top portion 418 may be bonded to body 412 by threaded cylindrical body base 422.

In some embodiments, the level of probiotic present is within the range of about 1×105 colony forming units (cfu) per gram formula to about 1×1010 cfu per gram formula. In other embodiments, the level of probiotic present is within the range of about 1×106 colony forming units (cfu) per gram formula to about 1×109 cfu per gram formula. In some embodiments, the level of probiotic present is within the range of about 1×106 colony forming units (cfu) per gram formula to about 1×108 cfu per gram formula.
Because many probiotics are sensitive to heat and may be damaged or killed if subjected to the heat treatment that is necessary for many food and drink products, the present invention provides the compartmentalized storage of a probiotic. In the present invention, the product contained within the container may undergo heat treatment or sterilization during the packaging process. After the product has been packaged into a container and sterilized, a seal containing a probiotic layer may be affixed to the container. Alternatively, the probiotic may be contained on an insert as described herein or may be coated within the upper portion of the container or the container closure. The package may then be prepared for shipment or display. In these configurations, the probiotic is not subjected to damaging heat treatment during packaging and is kept separate from the product itself until consumption, at which time the two can be intermixed.
Thus, in some embodiments, the invention comprises a method for making a delivery apparatus comprising a) providing a container as described herein, b) filling the container with a product; c) sterilizing the product-filled container; d) sealing the container with a laminate seal as described herein; and e) placing a closure on the container.
The product contained within the container may be any product known in the art. In some embodiments, the product is in a form selected from a liquid, ready-to-use product, liquid concentrate, fluid, powder, suspension, emulsion, or combination thereof. In some embodiments, the product contained within the container is a food or drink product. In a particular embodiment, the product contained within the container is a nutritional supplement for children or adults.
