Description

Coffee capsules for coffee machine {coffee capsules for coffee machine}

The present invention relates to a coffee capsule for a coffee machine, and more particularly, for a coffee machine capable of extracting a coffee beverage with improved taste and aroma by increasing the residence time of the feed water injected into the coffee capsule filled with beverage powder It is intended to provide coffee capsules.

As the daily life of modern people progresses and becomes specialized, a myriad of devices that can be used and utilized simply and efficiently in daily life and social life are being developed. It is one of the devices made possible.

A coffee extraction device such as a so-called coffee maker is a device for producing coffee that is mainly drunk by heating water, such as coffee, black tea, and cocoa, and a heating steam device that heats water stored in a water tank and supplies it at high pressure, and the above. A coffee extracting device unit that supplies hot water and steam from a heating steam device to the capsules loaded in the capsule extraction device to extract a liquid coffee beverage, and discharges the capsule, and the liquid coffee discharged from the coffee extraction device is placed in a cup. A cup holder for receiving and a capsule storage container for receiving and storing discharged capsules are installed inside the housing, and a disposable coffee capsule filled with powder ingredients for preparing coffee is separately provided.

As is already known, in the coffee extraction device such as the so-called coffee maker, the operation of the extraction cycle of the device for extracting the coffee powder in the form of powder filled in a one-time package, that is, a disposable coffee capsule, into liquid coffee is automated.

In the automated coffee extraction device, when the user operates the button, the disposable coffee capsules are loaded in the extraction device from the plastic container, and the extraction device operates to make a hole in the disposable coffee capsule and supply high-temperature water and water pressure to the liquid. The coffee is filled in the cup in which it is placed, and the disposable coffee capsules in which the coffee undiluted solution is exhausted are dropped into the collecting bin.

As such, as consumers' interest in coffee capsules, which is easy to drink by putting disposable coffee capsules into a capsule machine, continues to increase, the related market is growing every year.

According to Euromonitor, a global market research company, the size of the capsule coffee market increased from KRW 44.5 billion in 2015 to KRW 143.4 billion in 2019, and the sales volume of capsule machines increased from 120,000 units in 2011 to 65 in 2019 by one company with the highest market share. The cumulative sales of ten thousand units were recorded.

At this time, the above-mentioned coffee extraction device is easy to use because it extracts coffee extract water by supplying hot water and water pressure by punching a hole in the lower surface of the capsule and the cover paper of the coffee capsule by means of a perforation pin, and the coffee extraction device after coffee extraction The coffee capsule related prior art has been proposed to further strengthen the advantages because it has several advantages, such as being able to use a certain amount of coffee and maintaining a constant coffee taste.

Disposable capsule (Korean Patent Application Laid-Open No. 10-2012-0119193) having the powder of the proposed prior art 1 is a disposable capsule that allows beverages to be prepared by high-pressure steam spray or hot pressurized water. In the capsule, the capsule contains a powder such as a single-use coffee powder component, and is molded into a cylindrical shape using a flexible plastic or metal material that can be molded in a synthetic resin system and the capsule body and the capsule body Inverted column shape or truncated with an injection locking jaw extending to one end of the tip side and formed with a stepped jaw bent at an angle of 90° and a thin fragile layer that is located in the center of the circular plane at the lower end of the capsule body The lower end of the capsule body and the lower end of the capsule body to protect the penetrating portion formed in a conical shape and the penetrating portion, to facilitate storage and handling of the disposable capsule, and to induce smooth injection into the inner diameter of the circular holder of the capsule punching holder It extends and protects the penetrating part protection rim, which has a 15-20° angle and formed a curved inward inclined part, and the powder stored in the capsule body. A cap for a capsule cover in which a double-bonded aluminum (aluminum: AL) and polyethylene (PE) thin film is double-bonded so as to be supported by and a filter attached to the rim of the circular upper surface of the radiation protruding rib.

As in the prior art 1, in the coffee capsule-related technology, a technology for improving the external structure of the capsule container for improving the convenience of extraction from the coffee capsule has been developed. Since it is discharged, the beverage is not sufficiently extracted from the beverage powder, and thus the taste and flavor of the beverage are relatively poor.
