Description

[Detailed explanation of the idea] The present invention relates to an instant food container.

More specifically, the present invention relates to an instant food container having antiseptic and antifungal functions.

Generally, instant foods, excluding canned products, are sold in containers in a dry or semi-dry state, and consumers often pour boiling water into the containers and use the containers as tableware.

In this case, preservative and anti-mold measures are required at the distribution stage.

This is particularly a serious problem when semi-dry foods are used as all or part of instant foods.

The object of the present invention is to provide an instant food container that improves food preservation and mold prevention during the distribution stage of instant foods, and further simplifies the preparation of instant foods.

The instant food container of the present invention is an instant food container consisting of a lid part and a container part, with a ventilation hole provided in the lid part,
A vinylon film bag containing a water-soluble preservative is placed on top of the bag, and a moisture-impermeable sheet is attached to the top of the lid so as to isolate the ventilation holes and the vinylon film bag from the outside air. It consists of many things.

The instant food container of the present invention can be used for all kinds of instant food.

Examples include instant noodles, instant soup and rice, and instant rice.

The instant food container of the present invention consists of a lid part and a container part, which can be made of paper, a plastic sheet, a foamed plastic sheet, or a laminate thereof with a metal or plastic film.

The water-soluble preservative used in the present invention is one that is edible and harmless, such as alcohols and esters, and that emits vapor at room temperature and has antiseptic and anti-mold effects due to the vapor, and is made of vinylon film. Anything that gradually penetrates the membrane of the bag can be used.

Particularly suitable are methyl alcohol and ethyl alcohol.

The membrane of the vinylon film bag of the present invention has the function of gradually permeating the water-soluble preservative sealed therein.

Moreover, the permeation rate increases as the outside humidity increases, so the higher the humidity of the food, that is, the more mold-prone the atmosphere, the more preservatives will be released, which is very convenient.

The dimensions and film thickness of the vinylon film bag of the present invention are appropriately selected depending on the capacity and material of the instant food container, the type of instant food, the period of distribution route, the type of water-soluble preservative, etc.

Furthermore, when the permeation rate of the water-soluble preservative is too high, the vinylon film bag of the present invention is made by laminating a moisture-impermeable film with many small holes in the vinylon film. It is desirable to be able to use things.

The permeation area is limited by the area of these pores.

In the present invention, since the vinylon film bag is isolated from the outside air by a moisture-impermeable sheet, the vapor of the water-soluble preservative flows into the container through the ventilation hole provided in the lid.

The moisture-impermeable sheet of the present invention is a paper laminated with a metal or moisture-impermeable plastic film, or a moisture-impermeable plastic sheet.

This is adhered to the top surface of the lid of an instant food container while enclosing a vinylon film bag and a ventilation hole.

As for the method of adhesion, it is simplest to use mutual fusion of plastic films, but methods using adhesives and other methods can also be used.

The vent provided in the lid of the instant food container of the present invention is for introducing the vapor of the water-soluble preservative into the container.

This ventilation hole can be provided with a large number of small diameter holes or one large diameter hole.

In the latter case, this vent can also be used as a hot water inlet for cooking.

Furthermore, when the container is used as a pot for boiling, as in the case of nabeyaki udon, shiruko with mochi, and kamameshi, these vents serve as vents for steam to escape.

The present invention will be explained in more detail with reference to the drawings.

In FIGS. 1 and 2, a container for instant noodles is shown, and the lid 1 is made of paper laminated with a plastic film on the top surface.

The container part 2 is made of expanded polystyrene and is sealed with the lid part 1 after the instant food is put therein.

A ventilation hole 3 with a diameter of about 2 cm is provided in the lid part 1, and a rectangular vinylon film bag 4 is placed on top of the ventilation hole 3.
is placed.

A rectangular moisture-impermeable sheet 5 larger than the vinylon film bag 4 is placed over the vinylon film bag 4 and its periphery is fused by heat.

A vinylon film bag 4 is placed on the moisture-impermeable sheet 5 in advance.
It is preferable to bond them with an adhesive because when the moisture-impermeable sheet 5 is removed, the vinylon film bag 4 can be thrown away together with the moisture-impermeable sheet 5.

A tongue end 6 is attached to one end of the moisture-impermeable sheet 5.

The consumer can peel off the moisture-impermeable sheet 5 by pinching the tongue end 6.

Then, hot water can be poured into the vent hole 3 with the lid closed.

In this case, by using the instant food container of the present invention, semi-dried noodles can be used, and there is no need to put the semi-dried oysters and seasonings inside the noodles in a separate aluminum pack. .

Therefore, it is very convenient to be able to pour boiling water into the pot while cooking with the lid on.

As described above, the instant food container of the present invention makes it possible to preserve instant foods, especially instant foods including those in a semi-dry state, for a long period of time, and further simplifies cooking, which is very beneficial.
