Abstract

PURPOSE: To make an beverage flow out smoothly by constituting a beverage package in such a way that the outlet of the beverage package has a recessed part adjoining the outlet and a material covering the outlet is bent into the recessed part by piercing motion of a tool to move the material out of the passage of the beverage. CONSTITUTION: A beverage package 1 has an outlet nozzle 2 and the outlet nozzle 2 is surrounded by a wall 3 and a beverage flows through the outlet opening 4 of the outlet nozzle 2. The outlet opening 4 is covered with an aluminum foil 5. The aluminum foil 5 is hermetically sealed on the wall 3 but is not hermetically sealed on the outlet nozzle 2. A cutting tool 7 for opening the outlet of the package is constituted of a cylinder with a larger outer diameter dimension than the outlet nozzle 2 and the bow-shaped part 8 of the top end is formed into a serrated shape to cut the aluminum foil by piercing it. The straight rod part 9 of the cutting tool 7 is cut short to the base part of teeth of the serrated part and the outlet of the beverage package is opened by bending the cut aluminum foil into a recessed part 6. It is possible thereby to make the beverage flow out smoothly when the beverage flows out from the outlet as it is not brought into contact with the cut aluminum foil.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to beverage containers, in particular air and water impermeable containers.
le) a sealed beverage container made of material and containing one or more ingredients for preparing a beverage;

(Prior Art and Problems to Be Solved) Brewing freshly brewed tea or coffee (prod++ctioa) involves contacting tea leaves or roasted and ground coffee with boiling water to form a beverage. or separating it from ground coffee. Various methods of brewing freshly made coffee or tea are well known. For example, tea is traditionally prepared in a teapot, where the tea leaves are steeped in boiling water and remain there until poured from the teapot. Freshly made coffee can be made by continuously passing boiling water through roasted and ground coffee contained in a filter and collecting the coffee in a cup or other container, or by continuously pouring boiling water through roasted and ground coffee. Percolation (perc), which involves repeated passing
o1stio1: leaching filtration).

It has previously been proposed to seal freshly roasted and ground coffee or tea leaves in separate air- and water-tight containers. For example, it is known that cartridges or capsules filled with ground coffee are used in coffee brewing machines, commonly referred to as "espresso" machines. When making coffee using these machines, a cartridge containing coffee is placed in a brewing chamber and hot water under pressure is passed through the cartridge, which extracts the aromatic coffee components from the ground coffee. , and becomes a coffee drink.

Cartridges are also known in which hot water is passed by gravity through a cartridge containing roasted and ground coffee. This common type of cartridge is described in British Patent No. 13971.
It is described in No. 16.

In European Patent Application No. 873l 25.2 a container is described containing at least one beverage preparation ingredient, for example roasted and ground coffee. In a preferred embodiment of the container of this European patent, the container is formed of an air- and water-impermeable material and has a compartment for containing the beverage ingredients and to avoid the need for an external filter when the prepared beverage is used. and outlet means designed to be filtered.

The European patent application further describes a method for preparing a beverage. The method involves placing a container containing a beverage at a dispensing station, introducing water into the container through water introduction means, allowing the water to mix into the beverage, and dispensing the beverage so made into the container. It is constructed from collecting through a closed exit.

Beverage containers and cartridges such as those described above typically have an area adapted to form an outlet for the beverage from the beverage container in use. The outlet of the beverage container or cartridge is designed to be opened by the user during use, for example by means of a tear strip, a tear strip or a peelable tab. Alternatively, the beverage container or cartridge is
It can be designed for use in machines where the outlet of the container is opened automatically by cutting or piercing the material covering the outlet opening. Outlets automatically formed in beverage containers and cartridges by machines that cut or pierce the material with the outlet opening, as described above, have the disadvantage that the beverage is susceptible to splashing.

In the applicant's pending UK patent application no. ggoa6ay, the applicant described a beverage container with a sealed outlet. In the beverage container, the outlet has a counterbore (C
taterbot), the piercing action of the cutting or piercing tool folds the material surrounding the exit opening formed by the tool inwardly, so that the material lies inside the exit counterbore.

(Means to solve)

Claims (1)

Claims: 1. A sealed beverage container formed from an air- and water-impermeable material and containing one or more beverage preparation ingredients, the beverage container having an outlet nozzle formed in the beverage container; an outlet nozzle is surrounded by a wall, an air and water impermeable material covering the outlet nozzle is sealed to the wall, and the beverage container has a recess formed between the outlet nozzle and at least a portion of the wall, the recess containing the beverage. The recess is adapted to accommodate an air- and water-impermeable material covering the outlet nozzle during use of the beverage container for dispensing, and the material covering the outlet nozzle is partially cut around the outlet nozzle to form a drip plate. A beverage container, characterized in that the flap plate is folded away from the outlet nozzle while the outlet of the beverage container is being formed. 2. The beverage container according to claim 1, wherein the air- and water-impermeable material covering the outlet nozzle has the property of being appropriately foldable, so that together with the formation of the outlet in the beverage container, the recess adjacent to the outlet nozzle is formed. A beverage container characterized in that it remains bent inward. 3. The beverage container according to claim 2, wherein the material impermeable to air and water is aluminum foil or a laminated material. 4. A beverage container according to any one of claims 1 to 3, characterized in that the wall surrounding the outlet nozzle is rectangular, square, or circular. 5. The beverage container according to any one of claims 1 to 4, wherein the depth B of the depression is 2B≧A with respect to the width A of the hanging plate. 6. A beverage container according to any one of claims 1 to 5, characterized in that the recess entirely surrounds the outlet nozzle.
