Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a national entry of PCT Application No. PCT/KR2018/006922 filed on Jun. 19, 2018, which claims priority to and the benefit of Korean Application No. 10-2017-0093460 filed Jul. 24, 2017, in the Korean Patent Office, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present invention relates to a coffee vending machine that is capable of feeding water or steam to a capsule in which a material for coffee is contained to directly vend the coffee to a consumer.

BACKGROUND ART

A vending machine is a device for automatically selling goods, without a salesman, and if a coin, bill, or card is inserted into the vending machine to select a desired item or if payment for a desired item is finished through a mobile phone, the item is discharged from the vending machine. The vending machine is simply called an automated machine. The vending machines have been found in many countries, and according to investigation of Japanese vending machine industry association, the number of vending machines is 5,094,000 on 2013, which is substantially large. As various kinds of goods are sold through vending machines, further, the vending machines become more popularly introduced and used.

Generally, a variety of capsules for storing a powder, liquid or viscous material for long hours have been suggested. For example, as shown in FIG. 26, a coffee capsule plate CP (hereinafter, referred to as “capsule”) is suggested in Korean Patent Application Laid-Open No. 10-2004-0021918, which will be explained below.

The conventional coffee capsule plate CP has storage holes BW for storing coffee powder (not shown) and cutting grooves CH formed around the storage holes BW on a top surface of a sheet SH located on top thereof and an underside thereof. The cutting grooves CH serve to easily cut the capsules having the coffee powder stored in the storage holes BW to sets having appropriate numbers and also to easily open the capsules separated from the sets.

However, the capsule has to be one by one sold in a state where a salesman is standing by, which causes waste of labor forces. Besides, the capsule is drawn, and water is poured into the capsule to make coffee, which is inefficient in making the coffee and also requires a lot of time.

If beverages are sold through a vending machine, on the other hand, a consumer can drink the beverages contained in plastic, aluminum can, glass, and so on or the beverages contained in cups where a powder or liquid material is mixed with water.

As coffee as a kind of beverage has been recently very popular, various coffee vending machines have been developed and introduced. Further, consumers desire to have their brand coffee according to their preference. Under such a coffee trend atmosphere, accordingly, a coffee vending machine or a supplier for making or supplying the coffee vending machines have to satisfy the consumer's desire to drink his or her brand coffee.
