Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a rice carton for packaging rice that can be cooked without polishing (hereinafter referred to as unwashed rice).

[0002]

2. Description of the Related Art Generally, the milled rice contains nylon / polyethylene, polyethylene / polyethylene, nylon /
3 kg in a three-sided bag of vapor-deposited polyester / polyethylene, a polyethylene tube or a bag of laminated film, 5 kg
It is packaged in units such as kg, 10 kg, and 20 kg.
The three-sided bag, the polyethylene tube, and the laminated film bag are provided with microscopic holes, and when a large number of bags are stacked, the pressure causes the air in the bag to be exhausted from the microscopic holes. In this way, instability (load collapse) due to air in the packaging bag when the packaging bag is loaded is prevented, and the packaging bag is well installed.

[0003]

However, although such a packaging bag has good suitability for stacking, it is not suitable for long-term storage because it has small holes, and it is large in size and convenient to use at home. Was not good. Also,
The rice packed in this way is only buffed into rice and packed in a bag.Therefore, when cooking rice, it is necessary to grind the rice, especially when camping in Kawara and cooking rice. When Notogi soup was poured into the river, the river was polluted, which was not preferable in the natural environment. On the other hand, the technology of non-washed rice has been developed and it has become possible to cook rice without sharpening it, but it is necessary to have a container with excellent preservability for camping and disasters, etc. Since the packaging bag has minute holes, it is not suitable for such a case, and is also inappropriate in terms of size. Therefore, the present invention is mainly capable of storing and distributing unwashed rice that does not need to be sharpened for a long period of time, has excellent displayability at the store, and, in addition, does not require any other container for cooking rice and measures water. The purpose is to obtain a possible rice carton.

[0004]

The present invention provides the following carton for rice in order to achieve the above objects. That is, it is a rice carton that is configured by adhering an inner bag made of a film having a barrier property to a blank plate made of paper. A window portion is provided on the blank plate of this rice carton, and the outer surface of the blank plate is formed. A measuring line is provided near the window to make the inner bag a transparent film. Then, the side flaps on the blank plate of the rice carton are continuously provided through the lead ruled lines, and the inner bag is subjected to an easy-opening treatment and is filled with an oxygen absorber. . The rice to be filled in the rice carton of the present invention is rice that has been previously ground (non-washed rice).

[0005]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a rice carton before opening in the present invention, and FIG. 2 is a plan view of a blank plate of the rice carton. FIG. 3 is a plan view of an inner bag that is attached to the inner surface of a rice carton and attached, and FIG. 4 is a perspective view showing a state immediately after opening the rice carton.
First, the blank plate (A) shown in FIG. 2 will be described.
This blank board (A) is made of paper and has folding lines (9)
The sticking plate (1), the side plate (2), the front plate (3), the side plate (4), and the rear plate (5) are connected in series through the lead plate, and the side plates (2) and (4) have leads. Side flaps (6a) (6b) (6c) (6d) are provided through the ruled line (10), and top flaps are provided on the front plate (3) and the rear plate (5) through the folded line (9). (7a) (7b) and bottom flaps (8a) (8
b) are connected in series. Lead ruled line (1

(6b) (6c) (6d) and the side plates (2) (4) are dead line ruled lines that are cut so as to be foldable in both outer and inner directions in a continuous portion. In addition, the front plate (3) has a hole serving as a window (11) for checking the contents, and the side plate (4) has a window for measuring the amount of water added when cooking rice. The hole (12) is open. In the vicinity of the outer surface of the window (12),
A measuring line (13) is printed as a guide for measuring the amount of water added when cooking rice, which is convenient for measuring the amount of water when cooking rice.

Next, the inner bag (B) adhered to the inner surface of the blank plate (A) will be described. When the storage (circulation) period is relatively short, the film used for the inner bag (B) has a barrier property of, for example, about a two-layer film obtained by laminating polyethylene on a stretched nylon film or a stretched polyester film. Can have
In the case of a long-term storage (distribution) period, for example, an aluminum vapor deposition film, an aluminum foil film, or a transparent film, a vinylidene chloride coat film, a saponified film of ethylene-vinyl acetate copolymer, silica. A transparent film such as a vapor-deposited film is used between the two-layer films to improve the barrier property. The stretched nylon film and the stretched polyester film, which are base materials, are for imparting bag breaking strength and puncture strength, and polyethylene is for providing sealing properties.
In the present invention, the material of the inner bag (B) is a very important factor, and the storage period of rice and the gas barrier property of the film forming the inner bag have a close relationship, and when the product is stored for a long period of time, In particular, it is necessary to use a high barrier film.

The inner bag (B) made of the above-mentioned film is formed into a tube shape or a cylinder shape, and the cylinder shape is preferably a gastric seal generally called back sticking. FIG.
Shows an inner bag (B) which is tubularly attached to the back and cut into a predetermined size. The size of the inner bag (B) is such that, when expanded, the lateral lengths are the front plate (3) and the side plate (2).
(4) The rear plate (5) is made to have substantially the same length as the total width of the respective plates, and the vertical length is the height of those plates and the top flap (7a) and the bottom flap ( The height of 8a) should be approximately the same as the sum of the higher heights. Then, the inner bag (B), which is backed in a tubular shape, is a carton, that is, the front plate (3), the side plates (2) (4), and the rear plate (5) of the blank plate (A).
It is point-bonded or partially bonded by an adhesive to the inner surface of the. This adhesion method is, for example, after partially applying an adhesive to the adhesive plate (1), the side plate (2), the front plate (3), the side plate (4), and the rear plate (5), and then the inner bag (B ) Is adhered to the front plate (3) and the side plate (4), and then the rear plate (5) and the side plate (2) are folded over and adhered to the inner bag (B). At the same time, the adhered portions of (1) and the rear plate (5) are pressed and adhered. The top flaps (7a) (7b),
Bottom flap (8a) (8b), side flap (6
A) (6b) (6c) (6d) and the inner bag (B) are not adhered. In this way, the inner bag (B) is adhered to the blank plate (A) to form a rice carton (C).

[0008] The rice carton (C) thus obtained is filled with contents such as non-washed rice and packaged, but it is usually packaged using a dedicated packaging machine or the like. The typical filling and packaging steps will be described below. First, when the carton (C) for rice is supplied to the stacker and the packaging machine is started,
The feeder arm picks up the cartons one by one and inserts them into a rotating carton holder. At this time, the carton stands upright, and the film of the inner bag is spread along the inner wall of the carton in the opening shape of the carton. Next, the side flaps (6c) (6d) of the carton
The bottom flaps (8a) and (8b) are folded outward, the bottom of the inner bag (B) is sandwiched between heat seal plates, and heat sealed by pressure heating. And side flaps (6c)
(6d) and the bottom flaps (8a) and (8b) are folded inward, and the bottom is sealed by gluing or the like. After that, at the next station, the side flaps (6a) (6b) and the top flaps (7a) (7b) are folded to the outside, and the oxygen scavenger is enclosed to meter and fill the contents. Heat seal the top of the bag. Side flaps (6a) (6b)
When the (6c) and (6d) are folded outward, the side flaps (6a) (6b) (6c) (6d) and the side plate (2).
The side flaps (6a) (6b) (6c) (6) are formed by the lead ruled line (10) formed in the portion that is continuous with (4).
Since d) does not return to the inside, the filling loss of rice can be greatly reduced from the point of mechanical suitability. That is, the blank plate (A) used for the outer box of the rice carton of the present invention
Since the weight of the contents is large, it is necessary to have sufficient strength. Therefore, thick ones are preferable, and the thicker the side flaps are likely to return to the inside, the lead ruled line (10) as described above. This makes the filling process more effective. Then, finally, the side flaps (6a) (6b) and the top flaps (7a) (7b) are folded inside and the top of the carton is sealed by gluing or the like. From the viewpoint of the mechanical suitability of such a packaging machine, as the material of the inner bag (B), the composite film having a certain degree of hardness is less troublesome, and has better storability and productivity. However, it is preferable.

Further, when the opening of the inner bag (B) is heat-sealed, an oxygen scavenger is filled, gas is replaced with an inert gas such as nitrogen or carbon gas, or degassed with a gas bag such as a gas flush. Adjusting the gas composition in the inner bag (B) by a technique such as oxygen packaging is extremely effective in terms of long-term storability of the contents, which enables a long life of non-washed rice. Is. Regarding the method for encapsulating the oxygen absorber and / or oxygen indicator, the inner bag (B) may be fixed by a known bonding method (heat fusion, adhesive, etc.), or a pocket may be provided at the opening. If it is sealed in it or heat-sealed so as to be sandwiched between the heat-sealed parts at the top of the inner bag, and this oxygen absorber is removed at the same time as opening the bag, it can be used in a dark place without lights. When cooking rice, there is no need to worry about accidentally adding an oxygen scavenger to a rice cooker or rice cooker. Also,
If the end surface of the backing sticker seal is subjected to an easily-openable end treatment, for example, many fine holes (15) as shown in FIGS. 3 and 4 are provided, or scratches or notches are provided. It is extremely easy to open the fingers only.

The rice carton (C) packaged as described above is displayed and sold on the shelf in the same manner as general confectionery and food cartons at the store. A consumer who has purchased non-washed rice in a rice carton (C) opens the top with a zipper (14) for opening provided on the top flap (7a) of the carton when cooking rice, and then opens the inner bag. (B)
Cut off the upper part with scissors, or if it has been easily opened, open the inner bag (B) with your fingers, remove the oxygen scavenger, and transfer the unwashed rice to a rice cooker or the like. And
Water is put in the inner bag (B) of the empty carton, and a predetermined amount of water is put into the rice cooker or the like by using the measuring line (13) provided near the window (12) on the side of the carton. This window (1
The measuring line (13) provided in the vicinity of 2) is a standard for measuring the amount of water added when rice is cooked. Normally, add water to the indicated line and transfer it to the rice cooker. And cook the rice. The rice carton (C) of the present invention has a constant capacity because the inner bag (B) is in close contact with the inner surface of the carton, and the amount of water added for cooking rice can be measured. In this way, the measuring line (1
By using 3), there will be no failure due to water addition when cooking rice.
The measuring line (13) is extremely convenient and useful in a situation where there is no measure cup for measuring the amount of water, such as cooking rice outdoors at a campsite or cooking a disaster.

By the way, the rice, which is the content for carrying out the present invention, is non-washed rice that can be cooked by putting it in a rice cooker as it is without grinding it and adding an appropriate amount of water to cook it. Since this non-washed rice can be cooked immediately without polishing, it is very convenient for busy days, when water is not available enough due to a disaster, or for use at campsites, etc., and is also good for stockpiling.
Further, the rice carton (C) is, for example, of a size that can be packed and packaged in a quantity of 3 go, that is, a family of 4 per person, and is a single-use type. Therefore, not only in terms of storability, but also in terms of ease of use,
It is extremely effective, and is extremely excellent in terms of handling such as distribution and display in stores. In addition, since it is paper, it has excellent printability, has a good external appearance, can attract general consumers' willingness to purchase, and leads to sales promotion. It can also be used as a gift for gifts if various cartons are devised. In addition,
Even when the rice carton (C) is discarded, the blank plate (A) and the inner bag (B) are bonded by point bonding or partial bonding, so that they can be easily separated and can be separated and discarded. .
