とができる。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for extracting with hot water,
The present invention relates to an extraction package that can be extracted by adding water and heating by a microwave oven. 2. Description of the Related Art Conventionally, as an extraction package, an extraction object storage section is fitted into a container body having openings at the upper and lower sides, or is adhered to the lower opening of the container body. It has been proposed to attach and assemble. (Japanese Patent Laid-Open No. 1-2
[0003] However, in this method, an adhesive is required when the extractable material storage section comes off or adheres strongly, and a problem such as solvent odor occurs. . The present invention solves the above problem by devising a fitting structure between a container body and an extraction object storage section and a sealing structure of the extraction object storage section. In an extraction package comprising a cylindrical container body having an opening at the top and a storage part for the extract to be covered with a water permeable member on the upper and lower sides, the storage part has an outer peripheral edge, and a lower part of the container body. On the inner peripheral surface, a concave groove into which the outer peripheral edge of the storage portion is fitted is provided on the entire periphery and the upper water permeable member has
Non-transparent heat-shrinkable film shrinks with hot water on top
Adhesion with strength that can be peeled off by force
The lower part is an extraction package, which is sealed with a non-permeable film . Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a cross-sectional front view showing an example of the extraction package of the present invention. According to the present invention, as shown in FIG. 1, a cylindrical container body 1 having upper and lower openings 11 and 12 and an extract 2 to be extracted and covered with water permeable members 31 and 32 at the top and bottom. In the extraction package formed of the container part 3, the storage part 3 has an outer peripheral edge 4, and a concave groove 5 in which the outer peripheral part 4 of the storage part is fitted is formed in the lower inner peripheral surface of the container body part 1. It is an extraction package provided in. The outer peripheral edge 4 of the storage section is fitted into the concave groove 5 of the container body 1 so that the lower opening 12 of the container body 1 is formed.
Is reliably closed, so that hot water is poured into the container body 1 so that the extract 2 can be satisfactorily extracted from the storage section 3. The container body 1 has a cylindrical shape, for example, an inverted truncated cone, stores hot water 6 for extraction and the like, and stores the hot water 6 in the storage portion 3 of the extract 2 fitted in the lower opening 12. It serves to guide the water 6. The container body 1 is formed to have a size capable of storing, for example, one cup of coffee, and has heat resistance, for example, injection molding of polypropylene resin or polypropylene / ethylene-vinyl alcohol copolymer / polypropylene. Or a co-extruded film formed by vacuum or pressure forming. [0009] The lower opening 12 is, as shown in FIG.
Flange portion 121 which receives the outer peripheral edge 4 from below and a short cylindrical portion 12 having an inner surface which fits the outer peripheral surface 33 of the housing portion 3
Forming No. 2 is preferable because the sealing property is improved. As the extract 2, for example, coffee, black tea, green tea and the like are suitable. The upper and lower portions of the storage section 3 are covered with water permeable members 31 and 32 so that the extractable material 2 can be extracted through the hot water 6. Here, as the water permeable members 31 and 32, a perforated polypropylene film, Non-woven fabric and the like can be used. The upper part of the upper water permeable member 31 is bonded to a non-permeable heat shrinkable film 311 with a strength that can be peeled off by the shrinkage force of the hot water 6 and the lower water permeable member 31.
If the lower part is sealed with a non-permeable film 312,
It is sealed at the time of distribution, but for example, after removing the impermeable film 312 at the time of use, pour hot water 6 or fill with water, and when heated to a temperature suitable for extraction in a microwave oven, This has the effect that the heat-shrinkable film 311 is peeled off and the extraction is started. In this example, a polyvinyl chloride shrinkable film or the like can be used as the heat shrinkable film 311. The heat shrinkable film 311 is bonded to the water permeable member 31 in advance with a strength that can be peeled off by the shrinkage force of the hot water 6, and this laminate is formed. The heat-shrinkable film 311 is strongly adhered to the upper surface of the outer peripheral edge 4 of the housing portion 3 by the hot water 6 and peels off from the surface to be bonded to the water permeable member 31 while contracting. The non-permeable film 312 includes:
It is formed of a material having fragrance retention, easy sealability, and easy peelability, and can be formed of various materials. For example, a metal sheet such as an aluminum foil or a biaxially oriented polypropylene / aluminum foil / A multilayer film consisting of a sealant or hot melt adhesive layer, or
A multilayer film composed of a polyethylene terephthalate / aluminum foil / hot melt adhesive layer can be used. The non-permeable film 312 is bonded to the periphery of the lower opening of the storage section 3 by an easy-open heat seal. Is done. An outer peripheral edge 4 formed in the storage portion 3 has a shape protruding outward in a flange shape and has a size that can be fitted and sealed in a concave groove 5 formed in a lower inner peripheral surface of the container body 1. I just need. The concave groove 5 is formed at the outer end of the inner flange 121 on the lower inner peripheral surface of the container body 1 and has a depth such that the fitted outer peripheral edge 4 cannot be easily removed. Is preferred. In order to fit in such a state, the diameter of the outer peripheral edge 4 of the storage portion 3 is formed to be larger than the inner diameter of the lower inner peripheral surface of the container body 1 and to the extent that it fits into the concave groove 5. In addition,
The storage portion 3 is dropped downward from the upper opening 11 of the container body 1 and is forcibly pressed down, so that the outer peripheral edge 4 is formed.
Are temporarily deformed and fitted in the concave grooves 5, and the fitted state is firmly maintained by elastic recovery. As shown in FIG. 1, the non-permeable heat-shrinkable film 311 is turned up above the concave groove 5 so as not to be caught when heated by the hot water 6 if it is not fitted. It is preferable because it shrinks smoothly without any heat. In order to fit in such a state, if the diameter of the heat-shrinkable film 311 is set to be larger than the outer peripheral edge 4 of the storage section 3, the storage section 3 is positioned below the upper opening 11 of the container body 1. Then, by forcibly pressing down, only the outer peripheral edge 4 fits into the concave groove 5 and the heat-shrinkable film 311
Is easy because it is turned up above the concave groove 5. Further, by changing the material and composition of the heat-shrinkable film 311 and adjusting the temperature at which heat-shrinkage, ie, peeling, starts, extraction at an optimum temperature can be performed. As described above, the extraction container of the present invention comprises a cylindrical container body having openings at the top and bottom,
In an extraction package body comprising a storage part for an extract to be covered with a water permeable member on the upper and lower sides, the storage part has an outer peripheral edge, and the outer peripheral edge of the storage part fits on a lower inner peripheral surface of the container body. upper aqueous with a concave groove for engagement formed by providing the entire circumference
A non-permeable heat-shrinkable film is placed on top of the transparent member
Adhesive with a peelable strength due to the shrinkage force of
Make sure that the lower part of the transparent member is sealed with a non-permeable film.
Because it is a characteristic extraction package, it is sealed at the time of distribution, but there is no risk of the extractor's storage part coming off during use, and it is poured with hot water or filled with water and heated with a microwave oven At this point, the heat-shrinkable film is peeled off, and hot water comes in contact with the extraction target through this water-permeable member to perform extraction, and for example, coffee, tea, and the like can be easily obtained.
