[0013] FIG. 2 shows a front view of a container according to one embodiment of the invention;

[0014] FIG. 3 shows a top cross-sectional view of a multipack according to one embodiment of the invention; and

DETAILED DESCRIPTION OF THE INVENTION

[0016] The present invention provides beverage multipacks. The multipacks include the use of a functional sleeve or label on a beverage container. The label has an area that can be activated preferably by an inductive field to heat the area. The heated area activates a material that performs as an adhesive when heated. The activated adhesive is used to attach multiple beverage containers to form the multipacks.

[0017] FIG. 1 shows a multipack 100 according to one embodiment of the invention. The multipack 100 includes a plurality of containers 102. The multipack 100 according to FIG. 1 includes six containers 102. The multipacks of according to the invention preferably include at least two containers, although any number of containers may be used.

[0018] The containers 102 of the multipack 100 are arranged in longitudinal rows and transverse ranks. Each container 102 includes a label 104 that at least partially surrounds a portion of the container 102. As shown, the label 104 wraps around a circumference of the container, at a predominantly mid-point along a height of the container. This placement of the labels 104, specifically for bottles as shown in FIG. 1, is preferential as the labels are present along a widest part of the containers. As a wide variety of containers may be used including various shapes and sizes, the size and placement of the labels can be adjusted accordingly.

[0019] FIG. 2 shows a single container 102 of the plurality of containers. The label 104 is made up of a plurality of layers 106. One layer of the plurality of layers 106 includes a barcode 106a. Another layer of the plurality of layers 106 includes an adhesive bond 106b. The adhesive bond 106b allows for temporary adhesion through the use of an adhesive, activated through inductive heating or ultrasonic welding. The adhesive itself can be integrated into material used for the label 104, on the beverage container 102, or applied as a separate element. For example, in one embodiment where the plurality of containers are cans, the adhesive can come from polyethylene and/or polypropylene on the cans themselves. T

[0020] Another layer of the plurality of layers 106 includes a heat-absorbing element 106c. The heat-absorbing element 106c is preferably metal, or any other material that will heat up faster than the containers and their contents. The heat-absorbing or metal element 106c is enclosed within the plurality of layers 106 of the label 104. The metal element 106c can heat in an inductive filed and activate the adhesive element 106b on the label 104 so an adhesive bond forms with another container 102. The adhesive element 106b sticks to the adhesive element 106b of another container, resulting in an evenly-shaped multipack. However, the adhesive element is capable of sticking to any number of placements on a container.

[0021] As shown in FIG. 3, the adhesive element 106b on the label 104 of one container 102 sticks to an adhesive element 106b on the label 104 of at least one other container 102. As each container 102 of the plurality of containers that form the multipack 100 includes a label 104 with an adhesive element 106b, the plurality of containers stick to each other via the adhesive element 106b to form the multipack 100. In some embodiments of the invention where the containers are cans, an induction heater can heat up polyethylene and/or polypropylene on the cans to weld the cans together to form the multipack. Specifically, the metal element can heat a polypropylene coating on an outside of a plurality of cans so that the cans can be welded together.

[0022] Ultrasonic welding can also be used to activate the adhesive elements 106b to bond containers 102 together through the attached labels 104. For example, in embodiments of the invention where the containers are bottles (such as shown in FIGS. 1-2), the label can be used to weld the bottles together to form the multipack. The metal element can be a metal tape inserted in between individual bottles, or the labels can include the metal element. The bond area and strength of the connection to form the multipack 100 keeps the multipack intact until such time an end use consumer wants to separate a container from the multipack matrix. In accordance with embodiments of the invention, a beverage producer can quickly assemble beverage multipacks at a commercial scale without the need for a separate packaging product.

[0023] FIG. 4 shows a multipack 100 where the containers 102 are attached to one another in a staggered arrangement. As the adhesive layer 106b on the labels 104 of the containers 102 may surround the whole container, different multipack arrangements and shapes are also possible. Likewise, some embodiments may not include labels so the containers themselves can be welded together.

[0024] The invention illustratively disclosed herein suitably may be practiced in the absence of any element, part, step, component, or ingredient which is not specifically disclosed herein.

[0025] While in the foregoing detailed description this invention has been described in relation to certain preferred embodiments thereof, and many details have been set forth for purposes of illustration, it will be apparent to those skilled in the art that the invention is susceptible to additional embodiments and that certain of the details described herein can be varied considerably without departing from the basic principles of the invention.
