JPH10230920A - Frozen food tray for microwave oven - Google Patents

Abstract

PROBLEM TO BE SOLVED: To simplify the production process and eliminate superfluous packaging, by providing a plurality of dents on the flange of a container and connecting the container with the flange and the tray at a part of the dents as the connecting part. SOLUTION: Four containers 11 with flanges are integrally formed in a tray body 12 to constitute a frozen food tray for a microwave oven. The containers 11 with flanges are separated from the tray body 12, leaving only a part of the dents provided in four flanges in eight flanges 15. When the containers with flanges are separated from the tray body 12, the connecting parts 17 may be left to the containers 11 with flanges as burrs, but as the connecting parts are positioned at the lower never than the upper face of the flange 15a, the burrs do not injure one's lips when touching the burrs therewith.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frozen food tray for a microwave oven for storing cooked frozen foods such as meat potatoes and pumpkins.

[0002]

2. Description of the Related Art For example, a frozen food tray for a microwave oven for storing cooked frozen food such as meat and potatoes, as shown in FIGS. 3 and 4, a tray 2 provided with a plurality of container storage spaces 1; Containers 3 arranged in each container storage space 1
The tray 2 is vacuum-formed with a transparent polypropylene resin material, and the container 3 is vacuum-formed with a polypropylene resin material mixed with an inorganic filler.

[0003]

In the above-mentioned type of frozen food tray for a microwave oven, the tray and the container are separate from each other.
In addition to the excessive packaging, the manufacturing process requires a process of mounting the container in the container storage space of the tray, which complicates the manufacturing process.

[0004] The present invention has been made in view of the above points, and an object of the present invention is to provide a frozen food tray for a microwave oven which simplifies a manufacturing process and eliminates excessive packaging.

[0005]

A frozen food tray for a microwave oven according to the present invention is a frozen food tray for a microwave oven in which a container with a flange and a tray are integrally formed. And the tray are connected by using at least a part of these recesses as connecting portions.

[0006]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a frozen food tray 10 for a microwave oven according to the present invention.
No. 0 is vacuum-formed with, for example, a polypropylene resin material mixed with 30% of an inorganic filler such as calcium carbonate. The frozen food tray 10 for a microwave oven is formed by integrally molding four flanged containers 11 on a tray body 12.

As shown in FIG. 2, the container 11 with a flange is provided with a frozen food container 13 and the frozen food container 13.
And a flange portion 14 continuously provided at the upper end of the upper portion. The flange portion 14 is polygonal, preferably octagonal, and alternately has one of the eight flange portions 15.
It has a recessed portion 16. The upper surface of the concave portion 16 is located below the upper surface of the flange portion 15a, and a part of the concave portion 16 is connected to the tray main body 12 via the connecting portion 17. In order to easily cut the connecting portion 17, the width of the connecting portion 17 is preferably about 0.8 mm.

That is, the flanged container 11 has four flange portions 15 a of the eight flange portions 15.
Is separated from the tray main body 12 except for a part of the recessed portion 16 provided in the tray body 12.

Next, the operation will be described. For example, cooked frozen foods such as meat and potatoes are stored in four flanged containers 11 of a frozen food tray 10 for a microwave oven, and are commercially available as a package placed in an outer bag (not shown).

The user who has purchased the package containing the desired frozen food, tears the outer bag, separates the flanged container 11 containing the frozen food from the tray main body 12, and removes the flanged container 11 containing the frozen food. Is placed in an oven of a microwave oven, heated and placed for a predetermined time, and the frozen food in the flanged container 11 is cooked.

When taking out the cooked food from the oven, even if the temperature of the cooked food is high, the container 11
Is provided with a flange, so that the flanged container 1
1 can be carried by hand.

When the connecting portion 17 between the flanged container 11 and the tray main body 12 is cut, the connecting portion 17 may be burred and remain on the flanged container 11.
Since 7 is located below the upper surface of the flange portion 15a of the container 11, even if the lips are attached to the flange portion 15a of the container 11 and the cooked food is eaten and the soup is simmered, the lips are hit and the lips are hit. Does not hurt.

In the above embodiment, the frozen food tray 1 for a microwave oven having four flanged containers 11 is described.
Although zero has been described, the number of the flanged containers 11 can be changed as necessary. Further, the shape of the flange of the flanged container 11 is octagonal, but the number of polygons is not limited to octagonal as long as the shape can form a depression in the flange portion, and the flange portion is circular. You may.

[0015]

As described above, according to the present invention, the flanged container is integrally formed on the tray, and the flanged container is connected to the tray via at least a part of the recess provided on the flange. The burrs that occur when separating do not hurt your lips or hands,
In addition, the manufacturing process can be simplified and excess packaging can be eliminated.

[0016] Further, by calcu- lating the whole frozen food tray for a microwave oven using a polypropylene resin material mixed with an inorganic filler, the calorie of combustion as waste can be suppressed to a low level.
