The Beverage Package Of The Invention
The beverage packaging line may be formed with a body portion which also acts as the bottom of the package
. Alternatively, the body portion may be of an essentially hollow construction in which case the beverage package will have a flexible bottom portion sealed to the body portion adjacent the periphery of the bottom thereof.
Preferably the top portion of the package is made from a flexible material such as aluminium foil or a laminated material, such as a laminate comprising a metal layer laminated to a barrier layer of a plastics material. Many laminates of this type are known in the art and an example thereof is a polyester/aluminium/polypropylene laminate. The optional bottom portion of the
beverage package line may also be formed from a material of this type.
In one embodiment of the invention the beverage outlet channel is provided in a flange which forms part of the body portion. It is preferred, in this embodiment of the invention, that the flange provided in the body portion should totally surround the compartment containing the beverage ingredients, although it is contemplated that this will not always be necessary. Furthermore, it is also preferred that the beverage outlet channel should extend in the flange around the whole of the periphery of the compartment containing the beverage ingredients. However, the present invention also includes within its scope beverage packages in which the beverage outlet channel extends in the flange only along a part of the periphery of the compartment containing the beverage ingredients. For example, if the
beverage packaging machine is of elongate form then the beverage outlet channel may extend along the length of one long edge only.
In another embodiment of the invention a beverage outlet channel is formed along at least a part of the periphery of the compartment containing the beverage ingredients. for a package which is of elongate form a beverage outlet channel may be formed along one or both longitudinal edges of the compartment containing the beverage ingredients. Alternatively, or in addition, a beverage outlet channel may span the compartment containing the beverage ingredients.
The beverage package of the invention may be of any desired shape, although essentially round, rectangular or square packages are preferred. In an embodiment of the invention the package of the present invention preferably has an area which is adapted, when in use, to form an outlet for the beverage from the package. Alternatively, the body portion of the package may also have an outlet formed therein which communicates with the
beverage production line outlet channel. The outlet of the package may be designed to be opened, in use, by the user for example, by means of tear springs, tear strips or peelable tabs. Alternatively, the package of the present invention may be designed for use with a machine in which the outlet of the package is opened automatically by cutting or piercing, or by the pressure of the water introduced into the package and from which the beverage is made. In the embodiment of the invention in which the package has a region which is intended, in use, to form an outlet for the beverage from the package a V-shape channel may be formed which communicates with the beverage outlet channel so that the beverage is funnelled into a narrow stream for collection in an appropriate cup or other receptacle.
The beverage outlet channel formed in the body portion and the compartment containing the beverage ingredients communicate in such a manner that, in use, the compartment and the beverage outlet channel co-operate to act as a filter during the preparation of a beverage from the package. This can be achieved in a variety of ways. For example, when the
beverage packaging lines are formed in a flange which surrounds or at least partially surrounds the compartment containing the beverage ingredients, then the top portion of the package may be sealed not only to the body portion adjacent the periphery of the flange, but also at various points along the edge of the outlet channel which communicates with the said compartment. similarly, when the beverage outlet channel is formed along at least a part of the periphery of the compartment containing the beverage ingredients, the top portion of the package may be sealed to the body portion not only adjacent the periphery thereof, but also at various points along the edge of the outlet channel which communicates with the said compartment, for example by making appropriate spot welds of the top portion of the package package to this edge. The seals along the edge of the outlet channel may be formed by providing castellations in the edge to which the top portion can readily be sealed. In this manner, a plurality of very narrow channels or slots are provided connecting the compartment containing the beverage ingredients to the beverage outlet channel, thereby acting as a filter. It will be understood that the channels or slots should be of a size such that the majority of the roast and ground coffee particles are retained in the coffee bed. This will generally be achieved with castellation 0.2 to 0.5 millimetres high, depending upon the particular particle size of the coffee contained in the
beverage packaging machine .
Food packaging provides barrier protection to not only keep the product fresh, but also safe. Some products, for example, contain desiccants or oxygen absorbers to help extend shelf life. Modified atmospheres or controlled atmospheres are also maintained in some food packages. The importance of food packaging essentially creates a fake piece of armor that prevents harmful bacteria or other diseases from corrupting the food. Some products, like meat, may not even be removed from their original packaging but will still go bad because they were not kept in the correct temperature or environment. It's important to understand where to store the product not only before the packaging is opened, but also after it's opened because some types of foods have different needs.
Several materials are used either alone or in combination with other materials to provide proper food packaging. Aseptic processings help protect whole eggs while cartons provide protection for a batch of eggs. Plastic trays may protect fish or meats in combination with plastic wrap. Bags preserve and protect chips, crackers, and even salads while cans package soup, fruit and vegetables.
Did you know food packaging is a $110 billion per year industry? Food packaging is the third-largest industry in the United States. An estimated 350 billion packages exist on U.S. store shelves alone. While most types of packaging are necessary to provide proper health and protection for food products, many environmentalists are attempting to find ways to save on paper, plastic and other materials used for food packaging. Consumers may do their part by recycling packaging products (such as aluminum, glass and plastic) instead of throwing them in the trash.
