[Technical field to which the device belongs]

 The present invention relates to a packaging structure for powdered foods, and more specifically, for long-term storage of powdered foods such as powdered tea, powdered sake, powdered sugar, miso, powdered seasonings such as soy sauce, powdered spices, etc. The present invention relates to a packaging structure for powdered foods formed so as to be possible.

[0002]

[Prior art]

 Conventionally, this type of packaging structure is composed of, for example, a small bag for storing powdered foods such as a cup of powdered tea, an outer bag for storing a plurality of these small bags, and an oxygen scavenger that is put in the outer bag together with the small bag. There is something. In this case, the conventional pouch is typically made of a non-breathable sheet material 10 in which a cellophane layer 10a, a polyethylene layer 10b, an aluminum vapor deposition layer 10c, and a polyethylene layer 10b are laminated in this order, as shown in FIG. Met.

[0003]

[Problems to be solved by the device]

 By the way, in this type of packaging structure, it is usually difficult to vacuum-pack sachets because of the peculiarity that the stored items are powders. Therefore, in the case of this type of packaging structure, it is desirable that the deoxidizing agent acts so as to prevent oxidative deterioration of powdered tea or the like contained in a small bag for a long time.

However, in the conventional pouch, as described above, the polyethylene layer is formed in two layers with the aluminum vapor deposition layer sandwiched therebetween, and the cellophane layer is further laminated on the polyethylene layer to form an airtight sheet material. It had been. Therefore, in the case of the conventional structure, the action of the oxygen scavenger was stopped inside the outer bag and the inside of the pouch could not be degassed, so the contents such as powdered tea were oxidized and deteriorated by the air in the pouch, and as a result, the contents of this kind It was unavoidable that the storage period was shortened.

The present invention is intended to solve the problems of the conventional structure. Therefore, the technical problem of the present invention is to provide a packaging structure of powdered foods formed so that powdered teas, powdered seasonings, spices and other powdered foods can be stored for a long period of time.

[0006]

[Means for Solving the Problems]

 The present invention adopts the following technical means in order to solve the above problems. That is, the present invention is a package for powdered foods including a small bag 1 for storing powdered foods 2, an outer bag 3 for storing a plurality of the small bags 1, and an oxygen scavenger 9 to be placed in the outer bag 3 together with the small bag 1. In the structure, the above-mentioned pouch 1 is formed to have air permeability, and the above-mentioned outer bag 3 is formed in a non-air-permeable state.

In this case, according to the present invention, the pouch 1 is preferably made of a paper 1b whose inner surface is processed with polyethylene 1a. Specifically, it can be achieved by impregnating the inner surface of the high-quality paper with, for example, low-molecular-weight polyethylene within the range where the air permeability is not lost.

In the present invention, the outer bag 3 is preferably made of a sheet material 4 in which a polyester layer 4a, a dry laminate layer 4b, an aluminum vapor deposition layer 4c, a dry laminate layer 4b and a poly film layer 4d are laminated in this order. .

In this case, the powdered foods 2 include powdered seasonings such as powdered tea, powdered sake, powdered sugar, miso, soy sauce, and powdered spices. Of these, powdered tea is easily impaired in flavor and aroma due to oxidation, and powdered tea is a particularly suitable powdered food 2 for the present invention. In this case, any variety of tea may be used, such as gyokuro, sencha, roasted tea, oolong tea, and Darjeeling black tea.

[0010]

[Embodiment of device]

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Reference numeral 1 is a small bag for storing powdered foods 2. This pouch 1 contains 0.4 g of powdered tea as powdered foods 2 in this embodiment.

The above-mentioned pouch 1 is formed to have air permeability. In this embodiment, as shown in FIG. 1B, for example, a paper 1b whose inner surface is processed with polyethylene 1a is used. Specifically, high-quality paper is impregnated with low molecular weight polyethylene within a range not impairing air permeability. It consists of

Reference numeral 3 is an outer bag that stores a plurality of, for example, 20 pouches 1. The outer bag 3 is formed in a non-ventilated state. Specifically, in this embodiment, as shown in FIG. 3, the sheet material 4 is formed by laminating a polyester layer 4a, a dry laminate layer 4b, an aluminum vapor deposition layer 4c, a dry laminate layer 4b, and a poly film layer 4d in this order. . However, in the case of the present invention, it suffices that the outer bag 3 is formed in a non-ventilated state, and therefore the material of the sheet material 4 is not limited to that of this embodiment.

As shown in FIG. 1A, the surface of the outer bag 3 is displayed with a product name 5, a picture pattern 6 with tea leaves, etc., directly or through a label printed thereon. . The reference numeral 7 designates a cut-off line displayed laterally at the upper outer surface position of the outer bag 3. On the inner surface of the outer bag 3 slightly below the cutoff line 7, there is provided a resin-fitting chuck 8 used for opening and closing the mouth after opening. The outer bag 3 has its periphery 3a welded.

Reference numeral 9 is an oxygen scavenger which is put in the outer bag 3 together with the small bag 1. Examples of the oxygen absorber 9 include Ageless (registered trademark) manufactured by Mitsubishi Gas Chemical Co., Inc.

In the case of the present invention, since the pouch 1 is formed to have air permeability, the oxygen absorber 9 contained in the outer bag 3 acts not only in the outer bag 3 but also in the pouch 1. , Powder in the sachet 1 Prevents the food products 2 from being oxidized and deteriorated. The storage location of the outer bag 3 regardless of whether it is opened or unopened depends on the powdered foods 2 to be stored, but is usually preferably a cool dark place. Further, it is preferable that the outer bag 3 is filled with, for example, nitrogen gas as an inert gas in the product hermetic packaging process.

[0016]

[Effect of device]

 INDUSTRIAL APPLICABILITY As described above, the present invention has a packaging structure for powdered foods, which comprises a pouch for storing powdered foods, an outer bag for storing a plurality of these pouches, and an oxygen scavenger to be put together with the pouches in the outer bag. The above-mentioned small bag is formed to have air permeability, and the above-mentioned outer bag is formed in a non-air-permeable state. Therefore, according to the present invention, since the oxygen scavenger also acts in the pouch, it is possible to prevent the powdered foods contained in the pouch from being deteriorated due to oxidation and to preserve the powdered foods for a long period of time. Produce an effect.

Further, in the case of claim 2, since the pouch is made of paper whose inner surface is processed with polyethylene, according to this, not only can the ventilation state be changed relatively easily depending on the selection of paper, The cost of the pouch can be reduced.

Further, in the case of claim 3, since the outer bag is a sheet material in which a polyester layer, a dry laminate layer, an aluminum vapor deposition layer, a dry laminate layer and a poly film layer are laminated in this order, the outer bag is flexible. It can be formed into a state of nature.

Further, when the powdered food product is powdered tea as described in claim 4, it is possible to maintain a flavor unique to tea such as taste and aroma for a long period of time.
