Abstract

PURPOSE:To have the trouble of unsealing a seasoning container and prevent the hand and fingers and cooking utensils from being contaminated therewith by heating a container body packed with a main food and a hollow lid body containing seasoning such as sauce placed thereon with the accompanying heating of a heating body attached to a lid material. CONSTITUTION:A lid body 1, after being filled with seasoning such as sauce, is sealed with a lid material 2 at a fusion part 3 to form a hollow lid body A. A retort food is subjected to retort sterilization in this sealed condition. A heating body 4 is then attached to the lid material 2 at a suitable location thereof. The lid body 1 and the lid material 2 use the laminate material formed by building up in layers polypropylene, EVOH and polypropylene in that order as in the case of retort food pouch. In order for the retort food to be packaged as a main article, a container body B requires a hermetically sealed lid 9 to be placed thereon and an air-barrier packaging material is used for both the lid and container. In cooking such food by a microwave oven, the hermetically sealed lid 9 is removed from the container body B leaving the main food unsealed therein and the hollow lid body A is placed on the container body B for placement in the microwave oven.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a food container in which cooked foods such as yakiso-mage (fried fried noodles) and meat bowls and sauces to be poured on the foods are separately packaged. In detail, by simply heating the sealed container containing sauce and other seasonings in a microwave oven, etc., the sauce will automatically be added to the main food, such as fried noodles, stored in the container itself. This relates to a food container that can be sprinkled with sprinkles.

[Conventional technology]

Traditionally, packaging containers have been used to store main foods and seasonings such as sauce sprinkled on them separately.

There are various kinds on the market. However, in the past, the method used was to open a pouch of liquid seasoning, heat it in a microwave oven, etc. before or after heating it, and then pour it onto the main food stored in a sub-container.

[Problem to be solved by the invention]

However, in this method, it is necessary to open the pouch by hand or with scissors, which is time-consuming and may stain the hands and utensils.

[Means for Solving the Problems J Herein, the present invention provides a lid body molded from a thermoplastic resin, a lid material made of a thermoplastic resin fused to the lid body, and a lid material formed on the outer surface of the lid material at a suitable location. We have proposed a food container characterized by comprising a hollow lid comprising a heating element attached thereto, and a container body to which the hollow lid is removably engaged. While the main food is being heated in the microwave, seasonings such as sauce are automatically dropped onto the main food, eliminating the need for consumers to open the seasoning containers.

[Effect]

With the container structure of the present invention, by simultaneously heating the container body with the main food in the bag and the hollow lid containing seasonings such as sauce placed on it in a microwave oven, etc.
A heating element affixed to a suitable location on the outer surface of the lid material fused to the lid body generates heat, and the heat is generated by the lid material. When the thermoplastic resin melts, small holes are created in the lid material, allowing seasonings such as sauces sealed in the lid to fall through these holes.

It is permeated into the main food packed in the container body.

〔Example〕

Next, the present invention will be explained with reference to illustrated embodiments.

First, in FIG. 1, 1 is the lid body, which is filled with the contents, that is, seasonings such as sauce.

In the case of a normal retort food that is sealed at the fused portion 3 by the lid material 2 to form the hollow lid body A, it is sterilized in the retort in this sealed state. Next, a heating element 4 is attached to a suitable position on the lid material 2, and as shown in FIG. 6 is coated with a pressure-sensitive adhesive layer 7, and since there is a risk of it peeling off during retort sterilization, it is recommended that this heating element 4 is attached to the outer surface of the lid material 2 after retort sterilization. The size and number of the 5 heating elements 4 can be selected as appropriate as long as the seasoning such as sauce can be evenly spread over the main food packed in the bag.

In the case of retort food, the materials for the lid body 1 and the lid material 2 are 1, for example, polypropylene/EVOH/
A laminated material made of polypropylene is used. However, the material is not limited to this, and other barrier packaging materials such as polypropylene/PVDC/
Of course, it is also possible to use high-density polyethylene or the like.

Although the flange structure of the hollow lid body A is not specified, it is as shown in FIG.

If the structure has a fitting edge 8 that is continuous from the flat fused part 3, it can be fitted into the main body of the container where the main food is backed during the distribution stage, eliminating the need for shrink wrapping or an outer box. .

Further, when the main food is a retort food, the container body B requires a hermetically sealed lid 9, and both the container body B and the hermetically sealed lid 9 need to use barrier packaging materials as described above.

If the main food is chilled food, the container body B does not necessarily need a hermetic seal lid 9 (.

The material does not need to be a barrier packaging material, and in the embodiment shown in FIG. It is preferable to connect the hollow lid body A and the container body B using an auxiliary means such as the following.

FIG. 4 shows still another embodiment, in which a hollow lid A is mounted on a shoulder 10 formed at the upper opening of the container body B, and the sealing lid is sealed against a flange 11 of the container body B. 12, the hollow lid body A is also hermetically sealed at the same time.

When cooking in a microwave oven, etc., the container has a sealing lid 9 fused to the bottom of the container body.

First, the sealing lid 9 is peeled off to open the main food in the container body B, and the hollow lid body A is attached to the lid material 2 to which the heating element 4 is attached.
Place it on the bottom of the container with the side down, then put it in the microwave and cook. The temperature of the aluminum-deposited polyester heating element rises due to the microwaves in the microwave.
When the melting temperature of the material of the II material 2 is exceeded, a small hole will be formed in this part, so the seasoning such as sauce stored in the hollow lid body A will fall through this small hole into the main food in the container body B. It permeates through.

〔Effect of the invention〕

Since the present invention has the above-described structure and operation, seasonings such as sauces to be poured onto the main food can be automatically dropped and percolated onto the main food while the main food is being heated in a microwave oven.

Eliminates the need for consumers to open seasoning containers.

Moreover, it has the effect of eliminating the risk of staining hands and utensils.
