Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a double cooked rice package that is easy to handle and excellent in hygiene.

[Prior Art] It has been well desired from the manufacturing and distributor side as well as from the consumer side that rice cooked, so-called rice, can be handled sanitarily and easily for each transaction unit and distributed.

Manufacturers and distributors particularly demand that individual transaction units be easy to manufacture and easy to handle.
Cooked rice is sticky, and it is necessary to make it into a package in order to divide it into individual transaction units, but it is an important issue that deformation and damage does not occur in the distribution department. In addition, storability of contents and hygiene in handling are also important. And the ease of trading, that is, the ease of selling, is important.

On the other hand, from the consumer side, it is easy to buy individually, you can eat without using other eating utensils, you can eat even if your hands are dirty, you can eat while standing or walking. Is required.

By the way, the conventionally known techniques for packaging cooked rice are those packed in boxes or the like, those that are grasped and wrapped in bamboo skin, sutures, etc. The drawbacks of these cooked rice packages are that they cannot meet all of the above requirements, they require eating utensils such as chopsticks and spoons, and they cannot be eaten when the hands are dirty. However, it was not easy to handle. There was a similar problem with canned foods.

[Problems to be solved by the present invention] The purpose of the present invention is to cook easily anywhere, without the need for special eating utensils and without touching the rice directly. The object of the present invention is to provide a package, prevent deformation and destruction of containers and contents during distribution, and solve hygienic problems when eating.

In particular, cooked rice has a problem that it adheres to a container and is difficult to eat, but this problem is completely solved.

[Means for Solving the Problems] The present invention provides "1A. (A) Paper container body 1 having an anti-adhesion layer 2 formed on at least the inner surface of an inverted cone having an upper opening, and (b) paper. An inverted conical shape having an inner peripheral surface having the same inclination as the outer peripheral surface of the container body and a flange portion 4 having an upper end peripheral edge facing outward,
By bending the outer peripheral edge of the flange portion downward, the lid locking portion 5
And an outer container 3 for accommodating the paper container body described above, and (c) a peripheral bottom having an inner diameter that is the same as or smaller than the inner diameter of the paper container body 1 and is in contact with the upper end of the container body and the flange portion 4 of the outer container. A wall portion 10, an engagement peripheral wall portion 8 formed by bending the outer peripheral edge of the bottom wall portion downward, and a plurality of locking projections 9 protruding downward inward from the inner wall thereof are provided. However, there is a distance between the peripheral bottom wall 10 and the upper surface of the locking projection 9 that is slightly larger than the distance between the upper surface of the flange portion 4 of the outer container and the lower edge of the lid locking portion 5. Forming the fixed part 7,
Further, a lid 6 having an inner diameter on the upper surface of the locking projection 9 that is slightly larger than the outer diameter of the lower end peripheral portion of the lid locking portion 5 of the outer container is used to store the paper container body 1 in the outer container 3. The upper end of the paper container main body and the upper surface of the flange portion 4 of the outer container have the same height, and the lid body 6 is covered to cover the peripheral bottom wall portion 10 of the lid member with the upper end portion of the paper container body and the outer container. A container I in which the fitting fixing portion 7 of the lid body is detachably fitted to the lid locking portion 5 of the outer container and is brought into contact with the flange portion 4; A double cooked rice package consisting of cooked rice II, which has almost the same shape as the inner shape of the container. Regarding

The container body according to the present invention is made of paper, and the inner surface thereof is provided with an anti-adhesion layer, which is formed by laminating aluminum foil or a thin film of polyethylene on the paper, or by coating paraffin or polyethylene. These anti-adhesion layers are only for preventing the sticking of cooked rice, and the container body is paper. Therefore, this anti-adhesion layer does not make the container body difficult to break when eating. Since it comes into direct contact with food, it forms an anti-adhesion layer that is not harmful to hygiene.

The rice cooked in the present invention includes so-called cooked rice as well as steamed rice and rice. In addition to cooked rice such as white rice, seasoned rice, chestnut and mushrooms, red rice and the like are suitable. In addition, the side food may be embedded in the rice.

[Operation] In the present invention, since the sticking prevention layer is provided on the inner surface of the container body, the stored cooked rice does not stick. It is important to prevent this sticking and that the container be made of paper. That is, when eating the stored rice,
It is possible to easily eat by removing the lid, removing the lid locking cylinder, and smashing the container sequentially from above to expose the contents while eating. And, there is an effect that the contents can be eaten without directly touching the contents, without the need for other eating utensils, and without spilling. If the container body is made of synthetic resin such as polyethylene, polypropylene, polystyrene, or polyester by injection molding, vacuum molding, pressure molding, etc. instead of paper, the container cannot be broken and other eating utensils must be used. I can't eat. On the other hand, when mere paper is used, since rice cooking is originally an excellent adhesive for paper, even if the contents are taken out while tearing, most of it will stick to the torn container portion, making it difficult to eat. Therefore, it is absolutely necessary to use paper and to provide an anti-adhesion layer on the inner surface of the container of paper, whereby the above-mentioned action is exhibited.

Next, the structure for storing the container body in the outer container is
One is that, as mentioned above, paper must be used for the container body, and since the strength is weak, in order to detachably cover the lid with the required strength, it is necessary to fit and seal with this lid. This is because the fitting member of is required. Another reason is to prevent deformation and destruction of the paper container due to handling during distribution.
This is because a strong exterior body is required, and in order to satisfy these two requirements, the outer peripheral edge portion of the upper end of the opening of the exterior container is provided with a locking portion that fits with the lid body. Since the outer circumference and the inner circumference of the outer container of the paper container main body housed in this outer container have substantially the same inclination, they are in surface contact with each other and do not swing. Since the upper end of the container body after storage and the upper end of the outer container have the same height, when the lid is covered, the inner diameter of the peripheral bottom wall of the lid is smaller than the inner diameter of the upper end of the container body. The upper end of the main body contacts the peripheral bottom wall of the lid, and at the same time, the upper surface of the flange of the outer container also contacts the peripheral bottom wall of the lid. On the other hand, the lid locking portion of the outer container is fitted to the fitting fixing portion of the lid. In this way, the outer container and the lid are detachably coupled, but the container body is supported by the outer container and does not swing, and the upper edge contacts the peripheral bottom wall surface of the lid and moves upward. It cannot be fixed, and at the same time, the outer container provides sufficient support and reinforcement. Furthermore, the inner diameter of the locking projection of the lid is slightly larger than the outer diameter of the lower edge of the lid locking portion of the outer container, and the vertical distance of the fitting fixing portion is set to the lower end of the lid locking portion. Since it is slightly larger than the distance from the peripheral edge to the upper surface of the flange portion, the lid can be easily covered and removed, and the lid can be held well.

[Embodiment] The present invention will be specifically described with reference to the drawings.
