Description

[Detailed explanation of the idea]

[Industrial Application Field] This invention relates to brewing containers, and more specifically, it is possible to place a certain amount of raw materials such as coffee or tea inside the container, and to fit the containers in a stacked manner one after another. The present invention relates to an extraction container mainly used in a beverage vending machine, which can be sealed with an airtight sealing member. [Prior art] As a beverage vending machine, for example,
As described in Publication No. 37798, concentrated raw materials selected by the customer are heated or cooled and diluted with sugar and cream in a pot for selling beverages or pre-prepared in a mixing bowl. The majority of products are mixed and sold in pots because of their low operating costs, but they require storage of several cups of the undiluted solution and preservatives added to preserve food hygiene. Especially in the case of coffee as a savory beverage, instant coffee made from granulated or powdered ingredients still has a slightly lower taste (flavor and richness) than coffee brewed using the traditional method. As a result, beverage vending machines that sell regular coffee are now in practical use. [Problems that the invention aims to solve] However, in the case of conventional beverage vending machines that handle regular coffee, it is troublesome to automatically supply a fixed amount of raw materials and to dispose of brewed dregs after brewing (extraction) is completed. Since it is difficult to prevent moisture in finely ground coffee beans, the raw material has to be fed little by little frequently, which increases operational costs and increases the cost per cup. [Purpose of the invention] The purpose of this invention is to eliminate the above-mentioned drawbacks, protect the raw materials from moisture, and facilitate automatic supply of raw materials, extraction thereof, and disposal of brewed dregs. be. [Summary of the invention] In order to achieve the above-mentioned purpose, this invention has a step part formed at the bottom of the side wall of the container at the top of a certain amount of raw material put into a container with an opening and an integrally molded bottom plate. The raw material is hermetically sealed by installing an airtight sealing member such as a membrane or polyvinyl alcohol thin plate that can be broken with hot water, and the container is made to polymerize up to the stepped part, and a large number of fine particles are attached to the bottom of the container. Filter holes are provided so that the raw material can be extracted through the fine filter holes. [Configuration of the embodiment of the invention] As shown in FIGS. 1 to 3d, the extraction container 1 of this invention is composed of an extraction container 1 and an airtight sealing member 9. The container 1 is made of synthetic resin for casting, and includes a raw material storage portion 14 formed of a bottom portion 2 having an opening 4 and a side wall 3 that connects and slopes inward;
A stepped portion 15 extending horizontally slightly outward from the bottom portion 2 forming the upper edge of the side wall 3, and a side wall 16 having an overhang portion 5 on the outer edge of the stepped portion that is slightly inclined outward. The hot water pouring section 18 stores the poured hot water for extraction, and the hot water soluble airtight sealing member 9 is stretched over the stepped section 15. The solution for the special hot water-soluble airtight sealing member 9 is as follows: (1) Gelatin solution 5gr gelatin + 200ml water (2) Agar solution 6gr agar + 200ml water (3) Gelatin lactose solution 5gr gelatin + 2.5g lactose
+ 200ml water (4) Gelatin glucose solution 5gr gelatin + 2.5gr glucose + 200ml water (5) Dextrin solution 10g dextrin + water
200ml (6) Polyvinyl alcohol solution 10g polyvinyl alcohol powder + 200ml water etc. is preferable, and the size of the filter paper is 48cm as shown in the table below.
cm The amount of hot water (90° to 92°C) injected is 140 ml, and the solution is impregnated and dried to eliminate air permeability.
The blanching and filtration time for items that have not been impregnated at all or that have been once blanched and dried are those that have been impregnated with a gelatin solution, dextrin solution, or polyvinyl alcohol solution that does not pose a food hygiene problem even if eluted, and then dried. It is most preferable because it has good air permeability prevention ability and the blanching filtration speed is more than twice as fast as that of ordinary filter paper, which helps shorten the extraction time.

[Effect of invention]

The extraction container 1 of this invention is constructed as described above and is stacked in stacks, and when in use, it is stored in a beverage vending machine (not shown) and opened by the customer's purchase operation. One piece is taken out on the drilling table 61 of the part 60 as shown in FIG. 3a. When this extraction is completed, a pair of opening mechanisms 62
A, 62b are cylinders 63a, 63b using electromagnetic or fluid pressure, and piston rods 64a,
64b is sent out, and the press plate 65a attached to the tip thereof is applied to the upper surface of the overhanging part 5 of the container to prevent the extraction container 1 from being lifted up, and the hole drill 65b is inserted into the third
As shown in Figure b, insert it into the bottom part 2 of the extraction container 1,
A large number of small holes 41 are formed to form fine filtration holes 10, and as described above, a device is designed to prevent the extraction container 1 from lifting up. When the small hole 41 for extraction is completed in the bottom part 2 of the extraction container 1 in this way, it is sent to the extraction part 7 as shown in FIG. A part of the seal member 9 is melted and hot water is poured into the extraction container 1. This extract is poured through a funnel 73 integrated with the extraction table 72 with a small hole in the extraction part 7 into the cup 80 already taken out from below from a cup supply device (not shown). When one cup of coffee has been extracted, the sweeper 74 operates, and after the extraction is completed, the brewing container 1 with remaining brewed dregs is discharged from the brewing table 72 into the extraction container collecting tank (not shown). Upon completion, the beverage vending machine goes into standby state for the next customer. [Effects of the invention] As described above, this invention has a starch film or polyvinyl alcohol on the stepped part formed at the bottom of the side wall of the container at the top of the container with an opening and a fixed amount of raw material put into the bottom integrally molded container. An airtight sealing member such as a thin plate that can be broken with hot water is provided to airtightly seal the raw material, and the container is made to allow polymerization up to the stepped portion, and a large number of fine filtration holes are provided at the bottom of the container. Since the raw material can be extracted through the fine filtration pores, moisture in the raw material can be completely prevented, and the aroma and flavor of freshly ground regular coffee or black tea will not be affected, and the raw material can be extracted automatically for one person. A brewing container containing medium-finely ground regular coffee or black tea can be carried into the brewing section, and the brewed dregs and container can be disposed of together, so regular coffee or black tea can always be brewed in a new brewing container. It is hygienic and can be used not only in vending machines but also as a household extractor, and has a wide range of uses.
