Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to improvement of a packaging pack for microwave oven food,
More specifically, a plastic container having a bulging portion fitted and heat-bonded to the upper end of a plastic container and having a steam vent hole at the bottom is provided on the upper surface of a plastic inner lid with a through hole at a position corresponding to the bulging portion upper surface. The present invention relates to a packaging pack for microwave oven foods, in which a film upper lid is heat-bonded.

(Prior Art) With the widespread use of microwave ovens in recent years, a large number of microwave oven foods that can be eaten only by heating them in a microwave oven have been commercialized.
For example, pre-packed packed food or cooked food, which is a processed food filled in a plastic packaging pack (bag or container) and sterilized or cleaned, is placed in a heat-resistant plastic pack, hermetically sealed, and retort (pressurized). Retort foods and the like, which are sterilized by heating in a steam pot, are generally known.

(Problems to be solved by the invention) However, in the conventional microwave food described above, a suitable cutout is provided in the packaging pack (bag or container) with scissors in advance before putting it in the microwave to remove gas such as water vapor. There was a great inconvenience that had to be formed.

Especially when the packaging pack is a plastic container and plastic film, and when the container is not a shallow tray but a deep cup, steam and air will automatically and properly escape when used. There was no suitable microwave food packaging pack that could be served on the table as a processed food containing a suitable amount of water.

(Means for Solving Problems) The present invention has been made to solve the above problems, and is configured as follows.

That is, the packaging pack for microwave food according to the present invention is fitted with a plastic inner lid having a steam vent hole at the bottom of a recessed portion having a bulging portion, which is heat-bonded to the upper end opening portion of the plastic container in which the processed food is stored. A plastic film upper lid having a through small hole at a position corresponding to the upper surface of the bulging portion is heat-bonded to the outer peripheral edge of the inner lid and the upper surface of the bulging portion so as to conceal the concave portion.

Next, the present invention packaging pack will be described in detail with reference to the following embodiments with reference to the drawings.

〔Example〕

First, 1 is a plastic container having a collar 2 at the upper end in which a processed food 3 is stored. Reference numeral 4 denotes a plastic inner lid in which a plurality of vapor vent holes 7 are provided in the bottom of a recessed portion 5 having a bulge portion 6 in the center and a collar portion 8 is provided at the upper end.

Therefore, in this invention, the inner lid 4 is fitted into the upper end opening of the container 1 and the flange 2 and the flange portion 8 are heat-bonded 9. Then, on the upper surfaces of the collar portion 8 and the bulging portion 6 of the inner lid 4, a plastic film upper lid 10 having a through hole 11 at a position corresponding to the upper surface of the bulging portion is heat-bonded 12 and 13 so as to conceal the concave portion 5. It will be.

[Operating state]

When the processed food 3 contained in the container 1 is heated in a microwave oven, steam is generated inside. Then, the water vapor enters the inner lid 4 through the vapor vent hole 7, the heat-bonding 13 portion of the film upper lid 10 is peeled off as shown in FIG. 2, and the water vapor naturally escapes to the outside from the small through hole 11.

(Effect of the device) Since the packaging pack of the present invention is constructed as described above, it is very convenient because it saves the troublesome work of the conventional range pack.

Especially, in this invention packaging pack, water vapor and air generated inside properly escape naturally and safely.
The processed food has an outstanding effect that it can be eaten deliciously because the processed food contains a proper amount of water because the air escapes moderately. Further, the range-packed food of this packaging pack need only be put in a microwave oven, which is very convenient and can significantly improve the function of the conventional range-pack. It has the advantage that it can be used for deep cup containers.
