Description

  The present invention easily covers the drinking cup drinking mouth with the opening of the filtering filter bag greatly opened by covering the outside of the drinking cup drinking mouth with a locking frame attached to the filtration filter bag. It relates to a simple coffee bag that can be set.

  Household coffees sold in Japan are broadly divided into regular coffee that is extracted and extracted from coffee beans with an extractor, and instant coffee (including canned coffee) that is industrially made from the regular coffee. The consumption of coffee for home use has tended to increase rapidly in recent years with respect to the share of the total coffee market, and currently about half of it is consumed as home coffee.

  The history of the spread of instant coffee to date is that the import of coffee beans was completely liberalized in 1960, and many domestic manufacturers entered the instant coffee industry in the same year, and the import of instant coffee in the following year. As a result of the liberalization of the entire market, instant coffee was quickly spread to ordinary households as a result of a fierce sales battle, and drinking instant coffee at home became a habit.

  Currently, many instant coffees sold by domestic manufacturers are spray-dried by spraying hot coffee liquid in a high-temperature drying tube and drying quickly, or once the coffee liquid is at minus 40 ° C or less. It is manufactured by freeze-drying or the like in which it is frozen and then crushed into a vacuum to evaporate water.

  On the other hand, the regular spread of regular coffee has required a little time for the spread of instant coffee compared to the spread of instant coffee, as extraction equipment such as drippers and paper filters are sometimes required for extraction. However, regular coffee drinking gradually became common from 1980 to 1990, and since the latter half of the 1990s, simple coffee bags (one cup extraction type) that can enjoy regular coffee as it is without using an extraction device have become popular, The regular coffee market has been expanding rapidly over the last 20 years, as well as a growing preference for enjoying relaxation, free time, and drinking places such as coffee shops. The genuine coffee market and the future purchasing power will increase as the economic power becomes richer. It is expected to be large.

  Among them, regular coffee of paper drip system that anyone can easily brew a certain level of coffee is set with a paper filter (sprinkled paper) on a dripper (a kind of funnel), poured coffee powder and poured with an appropriate amount of hot water, Extraction is started after steaming for a while, and if you remove it before the hot water of the dripper is completely cut off, delicious coffee without miscellaneous taste can be easily brewed, so a certain consumer group that enjoys genuine taste has been established More recently, a simple coffee bag (one cup extraction type) that allows you to drink simple and authentic coffee by putting coffee powder in a filter bag and extracting it with water or hot water has rapidly expanded the market. Have been doing.

However, in order to easily brew delicious coffee using the simple coffee bag, it has been necessary to solve the following problems of the conventional simple coffee bag.
(1) The problem that it is difficult to pour hot water.
The correct way to pour regular hot water during regular coffee extraction is to first pour a small amount of hot water from the center of the coffee bag toward the periphery of the coffee bag as if writing the letter “No”, and gradually add hot water to the coffee powder. After pouring so that hot water spreads throughout, steam it for a while, then add the amount of hot water and pour it while watching the extract drop naturally from the extraction surface of the coffee bag. It is said to be drowning. However, if the hot water spout of the coffee bag is small, this work is difficult, and many of the conventional simple coffee bags adopt a structure that hangs a hanging piece on the drinking cup drinking mouth. Therefore, it was impossible to pour delicious hot water because the spout of the coffee bag was smaller than the spout of the beverage cup.

(2) The problem that the attachment method to a drink cup is troublesome.
The conventional method of attaching a simple coffee bag to the upper edge of the drinking cup's mouth uses a structure in which the hanging piece of the simple coffee bag is hung on the upper edge of the drinking cup's mouth. In addition, it is necessary to perform an operation of opening the latching piece, and it is necessary to hang a plurality of latching pieces one by one on the upper edge of the drinking cup, which is troublesome. It was time-consuming.

(3) The problem that the attachment to the beverage cup is unstable.
Many of the conventional simple coffee bag latches are made of non-rigid thin paperboard, so they tend to be hung in an unstable state at the drinking cup's mouth, and at the same time, It was difficult to put in the mouth, was troublesome, and was troublesome.

(4) Problem of disposal method of filter bag after extraction.
Conventional simple coffee bags do not have a temporary storage place for wet filtered filter bags after drinking, so prepare dishes such as dishes and cups in advance or discard them in the wet state. I had to take either action.

(5) Problems with simplicity and economy.
As a simple coffee bag, it is desired to have a shape and a structure that are simple in structure and easy in attaching means, and that can reduce the cost of manufacturing.

(6) The problem that the extraction method cannot be selected.
The regular regular coffee extraction method is to put coffee powder in a filter bag and drop water and hot water into it, and then add hot water to the coffee powder in the beverage cup. Waiting for a while, soaking method that drinks only the supernatant is often adopted, but since many of the extraction methods in conventional commercially available simple coffee bags adopt so-called drip soaking method that combines drip method and soaking method, The extraction method according to the taste of the drinker cannot be selected, and after the extraction of the drip method that is mild and free from miscellaneous extraction, it is impossible to follow up the extraction by adding richness and depth.

  Conventionally, a simple coffee bag that attempts to solve the above-described problems has been proposed. For example, “card coffee” (see Patent Document 1) in which a card-type extraction bag is put into a beverage cup has been proposed and is a known technique.

  However, the above-mentioned “card coffee” is a method in which a card-type extraction bag is directly put into a beverage cup, and although the problems of simplicity and economy of the coffee bag are cleared, the coffee bag is placed on the surface of the cup extraction liquid. Due to the direct immersion structure, there is a problem that the coffee bag is not maintained in a stable state in the cup, and there is a problem that it is difficult to pour hot water because the opening of the coffee bag is smaller than the drinking mouth of the cup. In addition, since the actual state of the sealed encapsulated bag is not described, the problem of the disposal method of the coffee bag after extraction and the problem that the extraction method cannot be selected cannot be cleared. Proposal with means to solve the problems of brewing all the above delicious coffees like coffee bags There was no.

  In addition, “coffee bags” (see Patent Document 2) and “extracted raw material packaging bags” (see Patent Document 3) of the type in which a packaging bag is cut and inserted into the drinking cup's mouth part are proposed and become known techniques. ing.

  However, since the above coffee bag has a structure in which the packaging bag is cut and inserted into the drinking cup, the problem of simplicity and economics of the coffee bag is cleared, but the coffee bag is made of the cup. The structure is soaked directly in the surface of the extraction liquid, so it is difficult to pour hot water because the opening of the coffee bag is smaller than the mouth of the cup, and the coffee bag is not maintained in a stable state in the cup. In addition, there is a problem that the extraction method cannot be selected, and since the actual situation of the sealed encapsulated bag is not described especially regarding the proposal of “coffee bag”, the problem of the disposal method of the coffee bag after extraction should be cleared All the delicious coffees mentioned above, such as the simple coffee bag of the present invention. It was not proposed comprises means for solving the problems for brewing over.

  Further, a “drip bag” (see Patent Document 6) provided with a plurality of engaging pieces for engaging a coffee bag with a beverage cup, or “article support body having a cited engaging piece” (see Patent Document 7). ) And “taste beverage extraction bag with holder” (see Patent Document 8) have been proposed and are well-known techniques.

  However, since the above-mentioned coffee bag is made of a thin plate material that can be caused by the engagement piece being stuck to the outer surface of the coffee bag, the problems of simplicity and economy of the simple coffee bag are cleared. However, there is a problem that the extraction method cannot be selected because of the structure in which the coffee bag is immersed in the extraction liquid surface of the cup, the problem that it is difficult to pour hot water from the structure where the opening is smaller than the drinking mouth of the cup, and the hanging Problem of how to attach the simple coffee bag to the beverage cup due to multiple members, and the problem of the disposal method of the bag body and the retaining member after extraction because the actual state of the sealed sealed bag is not described For brewing all the above-mentioned delicious coffee like the simple coffee bag of the present invention. It was not proposed comprises means for solving the problem point.

  The present applicant has a problem that when the conventional simple coffee bag is placed on the drinking mouth of the beverage cup, the opening of the filtration filter bag is not greatly opened, or the locking piece is easily set on the drinking cup mouth. Focusing on the problem of not being able to do so and improving the convenience by filling regular coffee or other powder into a simple coffee bag, whether these problems can be solved with a simple structure and inexpensive means Under the idea, a simple coffee bag comprising a hermetically sealed bag, a locking filter body composed of a filtration filter bag and a locking frame, and a hermetic packaging bag containing them was developed. This leads to the proposal of “bag”.
