Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for ready-to-eat food and the like having a hot water draining function.

[0002]

2. Description of the Related Art Instant foods such as instant noodles and instant yakisoba are reconstituted by pouring hot water, and then the hot water is discharged from a hot water outlet.
This is seasoned and served for food. The lids of these containers for storing ready-to-eat foods are roughly classified into a fitting type and an adhesive type. The fitting type lid (hereinafter, referred to as a fitting lid) is formed into a shallow dish shape that matches the outer shape of the upper end opening of the container body by hot plate molding a thin synthetic resin sheet such as polystyrene or polypropylene. This is fitted to the container body. In this case, the hot water cutout is provided in the fitting lid (for example, Japanese Utility Model Laid-Open No. 52-17).
No. 1540, Japanese Utility Model Laid-Open No. 3-11681, Japanese Utility Model Laid-Open No. 7-2249). An adhesive-type lid (hereinafter, referred to as an adhesive lid) uses a laminated sheet having a heat-sealable resin layer formed on the inner surface side of a lid substrate in a flat plate shape, and heats the laminated sheet to the upper edge of the opening of the container body. The upper end opening of the container body is sealed by being detachably adhered by welding (for example, Japanese Patent Application Laid-Open No. 5-16283).

[0003]

However, since the fitting lid needs to be formed into a dish shape, the processing cost is high. However, since the adhesive lid is used in the form of a flat plate,
It is cheaper than a fitting lid that requires molding. by the way,
As means for providing a hot water draining function in a container using such an inexpensive adhesive lid, it is conceivable to provide a hot water outlet in the adhesive lid. However, the adhesive lid having a hot water outlet is placed on the upper edge of the opening of the container main body as described above, and the adhesive lid is heated and pressed against the container main body by a heat press to perform heat fusion. If the cut end is positioned near the end of the adhesive lid so as to be close to the edge of the container body, the hot water cut end is displaced when the adhesive lid is displaced on the upper edge of the opening of the container body due to the pressure of the heating press. A problem that the upper edge of the opening of the container body is blocked easily occurs, and it is difficult to position the container body. On the other hand, if the adhesive cover is set at a position where the hot water outlet is sufficiently separated from the edge of the container body, there is a problem that the hot water draining, which is the original function, cannot be satisfied and hot water remains. .

An object of the present invention is to solve such a problem, and a cost reduction is achieved by using an inexpensive flat plate-like adhesive lid instead of the above-mentioned expensive fitting lid. It is an object of the present invention to provide a container for ready-to-eat foods and the like, which enables reliable and reliable hot water removal.

[0005]

SUMMARY OF THE INVENTION The present invention comprises a container body and a flat lid. The container body has a flange extending outward from the entire upper edge of the opening, and a flange is formed on the upper surface of the flange. A plurality of inwardly and outwardly extending drain grooves are arranged side by side at predetermined intervals in the circumferential direction of the flange, and the lid is peelably adhered over the entire circumference of the flange and so as to cover the upper part of the drain groove. It is characterized by being performed.

[0006]

According to the container for ready-to-eat food or the like having the above structure, the lid is peelably adhered over the entire periphery of the flange of the container body so as to close the drain groove, so that the airtightness is good before the peeling. The hot water can be poured into the container body by peeling off a part of the lid that is different from the hot water ditch when the stored food is consumed. Sometimes there is no fear that hot water leaks from the ditch.

At the time of hot water draining, the outer edge of the hot water groove covering portion of the lid is slightly peeled off from the flange to expose only the inner and outer outer ends of the hot water drain groove in the flange, and the container body is tilted. Can be performed quickly and reliably without causing the contained food such as noodles to flow out. Further, the hot water groove can be formed simultaneously with the molding of the container body.

The instant food container according to the present invention comprises a container body 1 and a lid 2 as shown in FIG. Container body 1
As shown in FIG. 1 and FIG. 2, is formed in a circular bowl shape in plan view having an inclined side wall surface 5 extending from the bottom surface 3 toward the opening upper edge 4 with a foamed resin material such as expanded polystyrene. A flat flange 6 having a predetermined width is formed to protrude outward around the entire periphery of the upper edge 4 of the opening. The outer peripheral edge 61 of the flange 6 is formed to be bent downward. The flange 6 is provided with a hot water drainer 7 on a part of the upper surface thereof in the circumferential direction. The flange 6 has a hot water drainer 7
The knobs 8, 8 are outward on both sides in the direction perpendicular to the flange (the intersection of the line P2 perpendicular to the line P1 connecting the hot water drain 7 and the bottom center point O of the container body 1 and the outer peripheral edge of the flange). It is formed in the shape of an overhang.

As shown in FIG. 3 to FIG. 9, in the above-mentioned hot water draining portion 7, a part of the flange 6 is formed into a corrugated cross section with the thickness of the flange, so that the hot water draining groove 9 having a U-shaped cross section and the crest are formed. The flat ridges 10 are alternately arranged in the circumferential direction. In this case, as shown in FIGS. 4 and 8, the drain groove 9 is not recessed over the entire length of the flange 6 in the inward / outward direction (width direction). A closed wall 11 that rises from the groove bottom to the flange upper surface 6a is formed. As shown in FIG. 4 and FIG. 7, the crest 10 between the adjacent hot water ditches 9, 9
Non-adhesive recess 10
a, an inner crest 10b is formed on the inner side of the flange from the non-adhesive recess 10a, and an outer crest 10c is formed on the outer side of the flange from the non-adhesive recess 10a.

The non-adhesive concave portion 10a of the peak portion 10 is formed as shown in FIG.
As shown in the figure, the height of the upper surface 6a of the flange 6 is slightly lower than the height of the upper surface 6a of the flange 6, for example, about 1.5 mm.
The inner ridge 10b is formed higher than the height of the flange upper surface 6a, for example, about 2 mm higher.
Is formed flush or substantially flush with the flange upper surface 6a.

As shown in FIGS. 10 and 11, the lid 2
A printed layer 13 is formed on the surface of a base material 12 made of paper or synthetic resin, and a metal layer 1 such as an aluminum foil is formed on the back surface of the base material 12.
4. A flexible laminated sheet (see an enlarged view in FIG. 11) formed by sequentially laminating the heat-sealing resin layers 15 is formed into a circular flat plate having a size enough to close the opening at the upper end of the container body 1. Do it. In the lid 2, a peeling direction and a peeling end point position are indicated at a position corresponding to the upper part of the hot water draining part 7 (a part for covering the hot water draining groove) and a hot water pouring side opposite to the hot water draining part 7, respectively. The peeling amount indications 16 and 17 are provided by printing or the like. The peeling amount display 16 applied to the hot water ditch covering portion of the lid 2 is provided so as to be located above the non-adhesive concave portion 10 a of the hot water draining portion 7 of the container body 1.
A knob piece 21 is provided on the outer end of the lid 2 corresponding to the hot water injection side.
Overhang is formed.

In order to adhere the lid 2 to the container body 1 in a closed state, the container body 1 contains an instant food 22 such as instant noodles or instant fried noodles, and then the lid 2 is attached to the container body 1.
Is placed horizontally on the flange 6, and the portion corresponding to the upper part of the flange of the lid 2 is heated and pressed against the flange 6 by a heating press. Then, the lid 2 is thermally fused over the entire periphery of the flange 6 via the heat-sealing resin layer 15. At this time, the lid 2 is simultaneously heat-sealed to the inner ridge 10b and the outer ridge 10c in the hot water drainer 7, but the heating press applies a constant pressure over the entire outer peripheral area of the upper surface of the lid 2. Since pressure is applied from above, there is a difference in adhesive strength between the adhesive strength at the inner crest 10b, which is higher than the flange upper surface 6a, and the bond strength at the outer crest 10c that is flush with or substantially flush with the flange upper surface 6a. The high inner crest 10b adheres strongly, while the lower outer crest 10c has a weaker adhesive strength. However, since a gap is formed between the non-adhesive concave portion 10a depressed between the inner peak portion 10b and the outer peak portion 10c and the lid 2, heat fusion is not performed.

When the lid 2 is heat-sealed by a heating press, the back surface of the flange 6 of the container body 1 is received and supported by a metal bucket B. In this case, not the whole back surface of the flange 6 but FIG. If the upper end of the bucket B is received and supported so that a part of the upper end of the bucket B fits into the concave portion 18 formed on the back surface side of the outer mountain portion 10c as shown by the two-dot chain line, the entire back surface of the hot water draining portion 7 is received. Bucket B can be made a simpler shape than a complicated shape bucket,
This simple shape is advantageous because the manufacturing cost of the bucket B can be reduced.

In the container having the above-described configuration, when eating food 22 such as instant fried noodles stored in the container, the handle piece 21 at the hot water injection side of the lid 2 on the side opposite to the hot water drainer 7 is provided.
The container is peeled off from the flange 6 to the position of the peeling amount display 17 applied to the portion, and hot water is poured from the portion of the container body 1 to allow instant noodles and the like to be absorbed and restored. In this case, the outside end of the drain groove 9 in the flange inward and outward directions is closed by the closing wall 11 and the upper part is covered by the lid 2, so that even if the hot water is almost full, the hot water is drained from the hot drain groove. 9 can be reliably prevented from leaking. Thereafter, the hot water ditch groove covering portion of the lid 2 is peeled off to the position of the peeling amount display 16 applied to the corresponding portion, and the hot water ditch 9
By exposing only the outer end side in the inward and outward directions of the flange to the outside, and tilting the container body 1 with the knobs 8, 8, the hot water is discharged from the hot water draining groove 9 to the outside.

At this time, a non-adhesive concave portion 10a which does not adhere to the lid 2 is formed at an intermediate portion of the ridge portion 10 between the adjacent drain grooves 9 and 9 in the inward and outward directions of the flange. When the peeling is performed with the outer edge of the groove covering portion as a starting point, the peeling is interrupted by the non-adhesive concave portion 10a. For this reason, it is possible to prevent excessive peeling, that is, peeling of the adhesive portion between the inner ridge portion 10b of the lid 2 and the upper portion of the hot water ditch 9 on the inner side of the flange in and out of the flange. This makes it possible to prevent the outflow of the contained food such as noodles due to excessive peeling. In particular, the inner ridge 10b is formed higher than the flange upper surface 6a to cover
It is strongly adhered to and greatly contributes to prevention of excessive peeling. The outer ridge 10c on the outer side of the flange with respect to the non-adhesive concave portion 11 is formed flush or substantially flush with the upper surface 6a of the flange and is formed lower than the inner ridge 10b. Is weaker than the adhesive strength between the inner crest 10b and the lid 2, so that when the hot water is removed, the outer edge of the hot water groove covering portion of the lid 2 can be easily peeled off as a starting point. it can.

At the time of draining, the container can be easily drained by holding the pair of knobs 8 and 8 and tilting the container body 1. In particular, even when the container body 1 is made of paper and is inferior to the container body made of a foamed resin in heat insulating properties, if the knobs 8 are provided as such, the container body 1 can be secured without feeling hot. This is preferable in that it can be tilted.

As shown in FIG. 12, the container body 1 is formed in a circular shape in plan view similarly to the above-mentioned embodiment.
In this case, an outwardly extending portion 20 is provided on a part of the outer periphery of the flange 6 at the opening edge of the container body 1, and the draining portion 7, that is, the draining groove 9 and the mountain portion 10 are provided on the outwardly extending portion 20. It is provided in the same manner as in the embodiment. According to this, most of the flange 6 other than the outwardly protruding portion 20 can be formed to have a narrow width, so that when the mouth is attached to the flange 6 to eat or drink the contents, the mouth feels palatable. Become.

The container body 1 is not limited to a circular shape in plan view, but may be a square or other polygonal shape in plan view as shown in FIG. In this case, on the flange 6 at the corner of the polygonal container body 1, a hot water draining portion 7, that is, a hot water draining groove 9 and a mountain portion 10 are provided in the same manner as in the above embodiment. According to this, it is possible to easily drain the hot water by tilting the corner of the container body 1 downward.

As a means for bonding the lid 2 to the container body 1, instead of the heat fusion in the above-described embodiment, a bonding agent having food safety can be used. As in the above embodiment, it is preferable that the hot water groove 9 be formed so as to cover the inside and outside of the flange at the outer end side with the closing wall 11 from the viewpoint of more reliably preventing hot water leakage when the hot water is full. The present invention is not necessarily limited to this, and it is possible to prevent the leakage of hot water by simply omitting the closing wall 11 and forming the outside end of the hot water groove 9 in the flange inside and outside, and closing the portion with the lid 2. .

As the crests 10 on both sides of the ditch 9 or the crests 10 formed between the ditch 9, an inner crest 10 b is formed at the same height as the upper surface 6 a of the flange. The outer ridge 10c may be omitted, as it is composed of only the two ridges 10b and the non-adhesive concave portions 10a formed on the outer side of the flange 10b.

[0022]

According to the present invention, a flat lid, which is less expensive than a fitting lid which requires molding, is used, and the drain groove can be formed simultaneously with the molding of the container body. An inexpensive whole container can be provided. Since the lid is peelably adhered to the entire circumference of the flange of the container body so as to close the hot water groove, there is no concern about leakage of hot water when pouring hot water. By only exposing only the outer end of the hot water draining groove in and out of the flange, hot water can be drained quickly and reliably without causing outflow of stored food such as noodles.
