DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for storing instant foods such as fried noodles and instant noodles, and a container body thereof.

[0002]

2. Description of the Related Art In this kind of ready-to-eat food container, a flange is projected outwardly from the entire periphery of an upper edge of an opening of a container body in which the ready-to-eat food is stored. It is releasably adhered by fusion and seals the upper end opening of the container body.

[0003]

However, since the width of the adhesive surface between the flange of the container body and the inner surface of the lid is the same over the entire circumference, the adhesive force with the flange of the lid has the same strength over the entire circumference. It has become. Therefore, when opening the spout of hot water for dissolving the ready-to-eat food at the time of cooking before a meal, a part of the lid is pinched and peeled off. At this time, the lid is peeled off too much and may be opened more than necessary. If the lid is over-opened in this way, there is a problem that when the lid is temporarily closed until the instant food is released after pouring hot water, the lid cannot be closed sufficiently. . In addition, when the instant food is yakisoba, a hot water outlet for discharging hot water after dissolving the fried noodles is provided in the container body, and at the time of hot water removal, a part of the lid covering the hot water cut is peeled off, At this time, too much peeling may occur, and there is a problem in that the fried noodles leaked out of the hot water outlet together with hot water.

SUMMARY OF THE INVENTION An object of the present invention is to solve such a problem. When the lid adhered to the flange of the container body is peeled off, the lid can be easily gripped and the lid can be prevented from being excessively opened. An object of the present invention is to provide a food container and a container body thereof.

[0005]

The instant food container according to the present invention comprises an upwardly open container body and a sheet-like lid for closing an upper end opening of the container body. In a ready-to-use food container in which a flange projects outward from the entire periphery of the flange, and the inner surface of the lid is removably adhered over the entire periphery of the upper surface of the flange, a part of the circumferential direction of the flange is Formed on a wide flange whose upper surface width is wider than the width of the flange upper surface at other locations that are continuous with the upper surface, and the adhesive force of the wide flange with the lid is smaller than the adhesive force of the narrow flange at the other position with the lid. The outer peripheral edge of the narrow flange is biased more inward than the outer peripheral edge of the wide flange, and the outer periphery of the lid adhered to the upper surface of the narrow flange. The peripheral edge is the outer peripheral edge of the narrow flange Those having features that protrudes outward. In this case, the projecting piece extends outwardly from the entire lower periphery of the outer peripheral edge of the narrow flange so that the projecting piece is lower than the upper surface of the narrow flange, and is aligned with the outer peripheral edge of the wide flange. Can be formed. In addition, a portion of the lid corresponding to the upper side of the narrow flange can be configured to be re-peelable so as to open a pouring port or a hot water spout.

In the container body of the instant food container according to the present invention, a sheet-like lid for closing the upper end opening is re-peeled on an upper surface of a flange protruding outward from the entire upper edge of the upper end opening. A container body of an instant food container adapted to be adhered to the container, wherein a part of the flange in the circumferential direction is wider than the width of the upper surface of the flange at another portion where the upper surface of the flange is continuous with the main body. The wide flange is formed so that the adhesive strength with the lid of the wide flange is stronger than the adhesive strength with the lid of the narrow flange at other places, and the outer peripheral edge of the narrow flange is The lid is biased inward from the outer peripheral edge of the wide flange, and the outer peripheral edge of the lid adhered to the upper surface of the narrow flange is formed so as to protrude outward from the outer peripheral edge of the narrow flange. Is characterized by the fact that

[0007]

According to the instant food container and the container body having the above-described structure, the adhesive strength of the lid to the flange of the container body is increased in the area of the wide flange and weakened in the area of the narrow flange. At the time of pouring or draining, the lid can be easily peeled off by peeling it off from the narrow flange.However, when it is applied to the area of the wide flange, the adhesive strength with the lid is strong, so the peeling up to that point Since it cannot be peeled off with force, opening the lid beyond the area of the narrow flange is suppressed. Thereby, the lid can be reliably opened in the opening range necessary for pouring or draining the hot water, and it is possible to prevent the lid from being opened too much.

[0008] Since the outer peripheral edge of the lid adhered to the upper surface of the narrow flange protrudes outward from the outer peripheral edge of the narrow flange, when pouring or draining the hot water, the outer peripheral edge of the lid at that location can be easily formed. The lid can be easily peeled off even if the tab piece is not provided on the outer peripheral edge of the lid.

When a projecting piece is extended from the entire lower periphery of the outer peripheral edge of the narrow flange, and the outer peripheral edge of the extended piece is aligned with the outer peripheral edge of the wide flange, a large number of container bodies are taken. After the molding, the individual container bodies may be cut straight without giving any irregularities to the outermost peripheral edge of the flange of the container body when the individual container bodies are separated, and the separation operation can be easily performed.

The instant food container according to the present invention comprises an upwardly open container body 1 and a sheet-like lid 2, as shown in FIGS. The container body 1 is formed by molding a foamed resin material such as foamed polystyrene or a non-foamed resin material, a paper material, or the like. In the illustrated embodiment, the vessel body 1 is shaped like a flat rectangular bowl. The container body 1 in the illustrated example is formed into a flat rectangular bowl shape having a rectangular bottom wall 3 and a peripheral wall 5 that rises upward from the entire periphery of the bottom wall 3 so as to expand.
A step 7 is provided on the inner periphery of the middle part in the depth direction of the peripheral wall 5, and the size of the upper end opening above the step 7 is lower than the step 7 in order to easily fit the instant food 17. The diameter is formed larger than the inner diameter of the part. The flange 6 is integrally formed to protrude outward from the entire periphery of the opening upper edge 5a of the peripheral wall 5 of the container body 1.

[0012] Of the four sides of the flange 6, two adjacent sides are formed on the wide flange 6a for increasing the width of the upper surface, while the other two adjacent sides are formed in a majority part thereof. The width of the upper surface is formed on the narrow flange 6b which is smaller than the wide flange 6a, and the other two adjacent sides are formed on the wide flange 6a continuous with the wide flange 6a. For example, the width of the wide flange 6a is about 14 m.
m, and the width of the narrow flange 6b is about 10 mm. The narrow flange 6b cooperates with the lid 2 to help form the opening of the spout.

As shown in FIG. 1, the outer peripheral edge 61b of the narrow flange 6b is deflected inward by a difference in width from the outer peripheral edge 61a of the wide flange 6a so that the outer peripheral edge 61b and the outer peripheral edge 61b are offset from each other. The portion 61a is made continuous with a stepped portion 61c. The outer peripheral edge 61 of the narrow flange 6b
A projecting piece 62b is formed so as to protrude outward from the entire periphery of the lower part of b so as to be stepped lower than the upper surface of the narrow flange 6b and to be aligned with the outer peripheral edge 61a of the wide flange 6a.

Wide flanges 6a, 6 on two sides of the flange 6
The corner portion where a intersects outwardly from the upper edge 5a of the opening, and the corner portion is formed in the narrow flange 6b, and the draining portion 8 is formed inside the narrow flange 6b. As shown in FIGS. 1, 2, and 5, the hot water drainer 8
A ridge 9 having the same height as the upper surface of the wide flange 6a and the narrow flange 6b, and the drain grooves 1 located on both sides of the ridge 9
0, 10 and the hot water grooves 10, 10 are formed lower than the upper surfaces of the wide flange 6a and the narrow flange 6b. The inner end of the hot water drain groove 10 is formed so as to communicate with the inside of the container body 1, and the outer end thereof has a narrow flange 6.
b is formed so as to be closed on the inside of the upper surface, and is hermetically sealed by the lid 2. Also in this hot water draining section 8, the outer peripheral edge 61b of the narrow flange 6b is biased inward by the width difference from the outer peripheral edge 61a of the wide flange 6a, so that the outer peripheral edge 61b and the outer peripheral edge 61b are shifted.
and a are made continuous through the stepped portion 61c. And
From the entire lower periphery of the outer peripheral edge portion 61b of the narrow flange 6b, the projecting piece 62b has a step shape lower than the upper surface of the narrow flange 6b,
Further, it is formed to project outward so as to be aligned with the outer peripheral edge 61a of the wide flange 6a.

At the hot water pouring port and the hot water draining portion 8, the overhanging piece 62 extends from the entire lower periphery of the outer peripheral edge 61b of the narrow flange 6b.
b, the outer peripheral edge of the overhanging piece 62b is aligned with the outer peripheral edge 61a of the wide flange 6a, so that a large number of container bodies 1 are formed, and the container bodies 1 are cut off individually. Since the outermost peripheral edge of the flange 6 of the container body 1 may be cut straight without making any irregularities, the separating operation can be easily performed. However, the overhanging piece 62b is not always necessary, and may be cut off after molding. Or overhang piece 62b from the beginning
It can also be formed into a shape without the mark.

On the other hand, as shown in FIG. 2, the cover 2 has a printed layer 14 formed on the surface of a paper or synthetic resin base material 13 and a waterproof surface such as aluminum foil or silica vapor deposited on the back surface of the base material 13. It is made of a flexible laminated sheet obtained by sequentially laminating the layer 15 and the heat-sealing resin layer 16. The lid 2 has a size around the outermost peripheral edge of the flat rectangular flange 6 of the container body 1, that is, a size around the outer peripheral edge 61a of the wide flange 6a and the outer peripheral edge of the projecting piece 62b of the narrow flange 6b. It is cut into a square shape of almost the same size.

In the container body 1 configured as described above,
As the instant food 17, for example, fried noodles are stored, and on this instant food 17, a fried noodle sauce in a bag, a sprinkle in a bag 18 and the like are separately attached. Thereafter, the lid 2 is placed horizontally on the entire periphery of the upper surface of the flange 6 of the container body 1, and the portion corresponding to the upper part of the flange of the lid 2 is
Is heated and pressurized. As a result, the lid 2 is thermally fused removably over the entire upper surface of the flange 6 via the heat-sealable resin layer 16, and the upper opening of the container body 1 is closed in a sealed manner.

When the lid 2 is heat-sealed, the heating press presses the entire circumference of the upper surface of the lid 2 from above with uniform pressure, so that the upper surface of the wide flange 6a has a large width and a large bonding area. The adhesive strength of the wide flange 6a and the adhesive strength of the narrow flange 6b cause a difference in adhesive strength between the upper surface of the narrow flange 6b and the adhesive strength of the narrow flange 6b. The adhesive is weakened in the latter narrow flange 6b.

The lid 2 having a size substantially equal to the size of the outermost peripheral edge of the flange 6 is formed by a part 2a, 2
As shown in FIG. 2, b is adhered so as to protrude outward from the outer peripheral edge 61b of the narrow flange 6b. Therefore, the portions 2a and 2b of the outer peripheral edge of the lid 2 are easily picked when the lid 2 is peeled off. When the overhanging piece 62b is formed, the overhanging piece 62b and a part 2 of the outer peripheral edge are formed.
Since a gap is formed between the cover 2 and the holes 2a and 2b, there is no problem in pinching the portions 2a and 2b of the outer peripheral edge of the lid 2.

Therefore, the instant food 17 is prepared at the time of cooking before meals.
Prior to pouring hot water into the interior of the container body 1 to release the hot water, the outer peripheral edge portion 2a of the lid 2 corresponding to the upper part of the narrow flange 6b is grasped and peeled off as a starting point. At this time, since the adhesive force with the lid 2 is increased by the wide flange 6a, in order to peel the lid 2 on the wide flange 6a, a force stronger than the peeling force up to that time is required. Required. For this reason,
The lid 2 is prevented from being opened beyond the boundary between the narrow flange 6b and the wide flange 6a, and can be prevented from being opened more than necessary.

The outer peripheral edge portion 2a of the lid 2 protrudes outward from the outer peripheral edge portion 61b of the narrow flange 6b, so that it can be easily pinched. Even if the knob piece is not provided, the lid 2 can be easily peeled off.

From the thus-opened hot water pouring opening, a bagged fried noodle sauce, a bagged sprinkle 18 and the like are taken out, and thereafter hot water is poured. After pouring the hot water, the spout is temporarily closed by the lid 2 until the instant food 17 is released. At this time, since the lid 2 is opened by a predetermined opening amount without being excessively opened, The pouring spout can be easily and sufficiently closed.

After the instant food 17 has been unscrewed, the portion of the outer peripheral edge 2b of the lid 2 corresponding to the portion above the hot water draining portion 8 is pinched and peeled off to open the hot water draining portion 8.
Since the outer peripheral portion 2b of the lid 2 protrudes outward from the outer peripheral edge 61b of the narrow flange 6b, it can be easily pinched and easily peeled off from the narrow flange 6b. Further, since the bonding strength between the wide flanges 6a and 6a and the lid 2 is strong, the wide flanges 6a and 6a do not open beyond the boundary between the narrow flange 6b and the wide flange 6a. The portion can be opened and opened by a predetermined opening amount covering the inner end portion. Therefore, it is possible to prevent the instant food 17 released at the time of the hot water drain from flowing out of the hot water drain groove 10 together with the hot water.

The container main body 1 is not limited to a flat rectangular shape, but may be a flat square or other polygonal shape, or a circular or elliptical shape as shown in FIG. The same applies. In the above-described embodiment, the case where the instant food requires hot water removal like yakisoba was described. However, in the case of the instant food that does not require hot water removal, it is not necessary to provide the hot water removing portion 8 in the container body 1. Needless to say. As a bonding means of the lid 2,
Instead of the heat sealing in the above embodiment, the bonding may be performed using an adhesive having food safety.

[0025]

According to the present invention, there is an advantage that the lid can be easily gripped when pouring or draining the hot water, and can be opened by a predetermined opening amount without being excessively opened.
