A typical single-serve beverage container is fabricated from various substrates and come in many different form factors and shapes. These include standard beverage cans with “pop top” or stay-on-tab lids, glass bottles with push-twist or pre-perforated closures as well as numerous other plastic designs. The majority of these containers hold beverage products that are typically carbonated or vacuum packed; from thermal sterilization processes. Additionally, existing containers also have a method of indicating whether or not the product has been previously opened or tampered with. Some of these methods are more obvious and effective than others, such as a permanent sheering of metal from itself in a beverage lid versus a tamper evident band around a perforated closure. Cans and bottles are the most popular formats for beverages with many brands using label designs and secondary packaging to differentiate themselves from others on shelf. Innovation in the beverage industry has driven much of the growth in consumption, however, this innovation has typically been limited to a packaging format (slim cans circa 2010) or formulation (spiked seltzer circa 2018) and rarely a combination of the two. It would be ideal for a new type of beverage packaging to stand out while also creating a potentially new category within the industry. The package would preferably be made of a sustainable material that is infinitely recyclable; such as metal, and provides the product protection and shelf life required for distribution through consumption. A new shape and physical appearance would differentiate the product on-shelf and provide an advantage within through the supply chain. Additionally, the package would feature a robust tamper evident system with additional functionality features such as recloseability, product authentication and digital interactive options. The package would be capable of accommodating product formulations from coffee-based drinks, alcohol-infused juices and mixers to specialty craft cocktails.
Furthermore, the package must be designed to accommodate high-speed manufacturing and leverage existing substrate supply chains to benefit from known economies of scale. The packaging could be configured such that they are nestable (stacked within each other) to allow for greater density during shipping. The package would be separate (de-nested) during the filling process using known methods.
One embodiment of the invention relates to a metal container with a conical or tapered sidewall profile. The container includes a top portion that is circular with a curled edge profile. The curled edge profile has a distinct radius so as to provide an appropriate sealing surface to match with a lid. The curled edge profile also provides for a safe, non-sharp, interface from which the end user is able to consume the product. The circular inside edge at the top has a diameter with the outside edge having a second diameter with a relationship of material thickness plus the curl diameter of the edge profile. The inside diameter of the container at the top is reduced according to the taper angle of the container which could be designed from 1 degree to 6 degrees relative to the vertical axis of the container. The bottom of the container has an integral wall connected to the conical/tapered sidewalls with an inside diameter and an outside diameter with a relationship of material thickness plus the inside diameter. Additionally the bottom of the container has a profile that is flat with indented sections that are either round or with defined radius or flat segments.
Another embodiment of the invention relates to a metal container with a conical or tapered sidewall profile and a defined geometry comprising of what are typically known as body beads in the can making/packaging industry. These beads are concentric and their number and design are determined by the final performance requirements of the package so as to survive the filling, sealing and distribution process.
Another embodiment of the invention relates to a metal container with a conical or tapered sidewall profile and lid. Whereas the container defined in [0001], [0002] and [0003] above is accompanied by a mating lid made also of metal comprising of an inner diameter and outer diameter, with an additional extended outer diameter created by an outward curl. The lid is applied to the top of the container and forms a hermetic seal to seal the contents stored within the metal container.
Another embodiment of the invention relates to a metal container with a conical or tapered sidewall profile and lid. Whereas the container defined in [0001], [0002] and [0003] above is accompanied by a mating lid made also of metal comprising of an inner diameter and outer diameter, and an inward curl. The lid is applied to the top of the container and forms a hermetic seal to seal the contents stored within the metal container.
Another embodiment of the invention relates to the metal lid described in [0004] and [0005] where the lid has a puncture or hole purposefully incorporated into the design. The hole is created during the manufacturing process and sealed using a polymer, polymer-derivative, foil membrane, or any material capable of preventing oxygen ingress/egress, into the package once the lid is applied and a hermetic seal is formed. The hole location can be placed in the center of the lid or offset in any direction circumferentially about the center of the lid.
Another embodiment of the invention relates to the metal lid described in [0004] and [0005] where the lid incorporates a tamper evident feature such as an audible “clicking” or “popping” sound when the seal above the hole in [0006] is broken.
Another embodiment of the invention relates to the metal lid described in [0004] and [0005] where the lid incorporates a visual inversion cue that indicates the package has been opened. This is a “button” feature on many lids today where the center panel of the closure is noticibly raised relative to the horizontal plane.
Another embodiment of the invention relates to the metal lid described in [0004] and [0005] where the lid incorporates a secondary authentication feature such as a QR or holographic imaging system. Other secondary systems also function as dual authentication and tamper evidence in a two-factor confirmation arrangement.
The figures illustrate a conical/tapered metal container 10. The purpose of container 10 is to provide a vessel for a new type of mixed or craft beverage that can be consumed as a single serving or occasion. Metal container 10 is produced and formed from a metal, such as steel or aluminum, which makes it ideal for recycling. Metal container 10 offers product protection and shelf life performance expected in the beverage industry while simultaneously providing a differentiated design and consumer experience.

A conical/tapered metal container in
A separate lid component 14 made of metal. The purpose of lid 14 is to perform as a closure for container 10 and create a hermetic seal once product is filled. Lid component 14 is made of metal, which makes it ideal for recycling. Lid component 14 can incorporate a number of commercially available and demonstrated technologies to provide for a method of tamper evidence notification and product authentication.
Lid component 14 has a diameter ϕ3 to the vertical outer wall 27 with diameter ϕ4 measured to the outer edge of curled finish 28. Lid diameter ϕ3 has a range between 1 to 4 inches and diameter ϕ4 has a range between 3.010 to 4.500″. The vertical outer wall 27 has a height of H2 ranging from 0.100″ to 0.500″.
Lid component 14 includes a liner or compound material 30 inserted in its inner channel made of a polymer, polymer derivative, rubber or other material acting as a seal.
Lid component 14 also incorporates a puncture 31 positioned anywhere about the horizontal plane 32. The puncture is meant to be sealed over with a polymer, polymer-derivative, foil membrane, or any material 33 capable of preventing oxygen ingress/egress.
Container 10 is made from a metal such as steel or aluminum. The metal provides a complete barrier to oxygen ingress/egress which provides super product protection and shelf life. Additional coatings are contemplated that are additive to the base substrate to protect the metal from filled product as well as corrosion from the environment. The coating system used could be a type of polymer or organic material; which also assists with the manufacturability of container 10 or 18.
Once container 10 is filled with a beverage product the component lid 14 is placed on top of the container, aligning the vertical outer wall 27 on the lid with the curled flange 18 on the container. A vacuum is keeps the lid in place once the product reaches ambient conditions; in particular during packaging, distribution and storage.
