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 yakisoba, are reconstituted by pouring hot water, and then the hot water is discharged from a hot water outlet, seasoned, and used 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 outlet is provided in the fitting lid (for example, Japanese Utility Model Laid-Open No. 52-171540, Japanese Utility Model Laid-Open No. 3-11681, Japanese Utility Model Laid-Open No. Hei 7-2249).
No.). Adhesive type lid (hereinafter referred to as adhesive lid)
The laminated sheet having a heat-sealable resin layer formed on the inner surface side of the lid substrate is used in the form of a sheet. The upper end opening is sealed (see, for example,
No. 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 sheet, the forming process is not performed. It is cheaper than the required fitting lid. By the way, it is conceivable to provide a hot water outlet in the adhesive lid as a means for providing a hot water draining function to a container using such an inexpensive 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 the cost can be reduced by using an inexpensive sheet-like 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 food or the like that can be easily and easily operated without draining the stored food.

[0005]

The invention according to claim 1 of the present invention comprises a container body 1 having an open top and a sheet-like lid 2 for closing an upper end opening of the container body 1. 1 has a flange 6 projecting outward from the entire periphery of the upper edge of the opening, and at least one hot-drain groove 9 recessed in a part of the upper surface of the flange 6 in the circumferential direction, The lid 2 is removably adhered so as to cover the entire upper surface of the flange 6 and the upper part of the hot water groove 9, and to be separated from one end to the other end of the hot water groove cover 21 of the lid 2. 16 is formed so as to pass perpendicularly above the middle part of the hot water groove 9 in the inward / outward direction of the flange.

According to the container of the first aspect, the lid 2
Is a hot drain groove 9 around the entire circumference of the flange 6 of the container body 1.
Is removably adhered so as to close the container, so that in the sealed state before eating, the airtightness is good and the storage quality of the stored food is excellent, and when the stored food is edible, it is different from the hot water groove cover 21 of the lid 2. Hot water can be poured into the container main body 1 by peeling off a part 22 of the other portion, and there is no fear that hot water leaks from the hot water drain groove 9 at the time of this hot water injection.

At the time of draining, the peeled portion 22 of the lid 2 is again adhered to the container body 1 and sealed, and the drain groove cover 21 of the lid 2 is cut off along the separating line 16 to partially remove the flange 6. Can be easily opened. At this time, since the separation line 16 is formed so as to pass orthogonally above the middle portion of the hot water groove 9 in the flange inside and outside, the portion outside the middle portion of the hot water groove 9 in the inside and outside of the flange is exposed. Although opened, the upper part of the inside of the hot water groove 9 from the middle part in the inside and outside directions is covered with the separation end 23 of the lid 2 which is left uncut on the container body 1. Therefore, by tilting the container body 1 after the hot water groove cover 21 of the lid 2 is cut off, only the hot water can be reliably poured out of the hot water groove 9 without spilling the stored food such as yakisoba.

According to a second aspect of the present invention, there is provided the container according to the first aspect, wherein:
A closed wall 11 rising from the groove bottom to the flange upper surface 6a is formed.

According to the container according to the second aspect, the upper part of the hot water draining groove 9 is covered with the lid 2 and the outer end side in the inside and outside of the flange is closed by the closing wall 11, so that the hot water is almost full. Even when the container is filled up to the state or the container is tilted carelessly, it is possible to reliably prevent the hot water from leaking from the drain groove 9.

The invention according to claim 3 is the container according to claim 1 or 2, wherein a plurality of the draining grooves 9 are arranged at predetermined intervals in a circumferential direction of the flange. A ridge 10 is formed between the grooves 9, 9, and an inner ridge that is at the same height as or slightly higher than the flange upper surface 6 a and adheres to the inner surface of the lid 2 at the inner end of the ridge 10 in the inward / outward direction of the flange. 10b, and a lid 2 at the same height as the flange upper surface 6a, at the outer end of the crest portion 10 in the inside and outside directions of the flange.
Outer crests 10c that adhere to the inner surface of
The flange upper surface 6 is located between the inner and outer crests 10b and 10c.
A non-adhesive concave portion 10a which is lower than a and does not adhere to the lid 2 is formed, and the separating line 16 is formed so as to pass above the inner mountain portion 10b.

According to the container of the third aspect, since the non-adhesive concave portion 10a which is lower than the upper surface 6a of the flange and is not adhered to the lid 2 is formed in the crest portion 10, the lid 2 is drained at the time of draining. When the groove covering portion 21 is peeled off from the flange upper surface 6a along the separation line 16, the draining groove covering portion 21 has a small peeling force by the amount of the non-adhesive concave portion 10a.
Can be easily peeled off.

Further, since the separating line 16 of the lid 2 passes above the inner ridge portion 10b, it remains on the container body 1 even when the hot water groove cover 21 is cut off along the separating line 16 and opened. Since the inner surface of the separation end portion 23 of the lid 2 remains in a state of being adhered to the inner mountain portion 10b, the state in which the separation end portion 23 covers the middle of the hot water drain groove 9 in the flange inward and outward directions is reliably held. Is done. Therefore, the lid 2
The separated end portion 23 does not rise from the inner mountain portion 10b, and the effect of preventing spillage of stored food such as fried noodles from the hot water drain groove 9 can be further enhanced.

The inner ridge 10b is formed slightly higher than the upper surface 6a of the flange, and the outer ridge 10c is formed at the same height as the upper surface 6a of the flange. Can strongly adhere to the inner ridge portion 10b having a higher adhesive force to the flange upper surface 6a. Therefore, when the hot water is drained, the separation end 23 of the lid 2 is removed.
There is no danger that the adhesive portion between the inner surface of the inner side and the inner hill portion 10b will be peeled off, so that the effect of preventing the outflow of the stored food 30 such as fried noodles can be further enhanced.

The invention according to claim 4 is the invention according to claims 1 to 3
Wherein the lid 2 is formed by laminating a waterproof layer 14 on the inner surface of the base material 12, and the separation line 16 is formed by perforations, and the perforations are formed only on the base material 12. Is what it is.

According to the container of the present invention, since the perforated fine holes are closed by the waterproof layer 14, the moisture permeation is excellent, and small insects and dust enter through the perforated fine holes. Can be prevented.

The invention according to claim 5 is the invention according to claims 1 to 4
Wherein the knob 2 is provided at a start end of the lid 2 at which the hot water groove cover 21 is cut off along the separation line 16.

According to the container according to the fifth aspect, when the hot water is drained, the knob 18 is provided, so that the opening / closing operation along the separation line 16 of the hot water groove cover 21 of the lid 2 is further facilitated. And the position of the separation start end of the separation line 16 can be easily understood.

The invention according to claim 6 is the invention according to claims 1 to 5

FIG. 3 is an enlarged sectional view of a hot water ditch portion of the container.

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. 3 and FIG. 4, a foamed resin material such as foamed polystyrene is formed into a square bowl shape in plan view having inclined side walls 5 extending from the square bottom wall 3 toward the opening upper edge 4. A flat flange 6 is formed over the entire periphery of the upper edge 4 of the opening so as to project outward with a predetermined width. The outer peripheral edge 61 of the flange 6 is formed to be bent downward. One side 62 of the rectangular flange 6 in a plan view is formed to be slightly wider than the width of the other three sides, and the width of the wide side 62 of the flange 6 is substantially equal to the circumferential direction (length direction orthogonal to the flange width direction). The hot water drainer 7 is formed over the entire length.

As shown in FIGS. 4, 8 and 9, in the hot water draining portion 7, a substantially U-shaped cross section is formed by forming a flange corrugated over substantially the entire length of one side 62 of the flange 6 in the circumferential direction. Cut grooves 9 and peaks 10 having flat peaks are alternately arranged in the circumferential direction. in this case,
As shown in FIG. 4 and FIG.
Is not formed over the entire length in the inward / outward direction (width direction), and a closing wall 11 is formed at the outer end of the hot water ditch 9 in the inward / outward direction of the flange from the groove bottom to the flange upper surface 6a. As shown in FIG. 4 and FIG. 6, the peak 10 between the adjacent hot water drain grooves 9, 9 forms a non-adhesive concave portion 10 a at an intermediate portion of the peak 10 in the inside and outside of the flange. An inner ridge portion 10b is formed on the inner side of the flange, and an outer ridge portion 10c is formed on the outer side of the flange from the non-bonded concave portion 10a.

The non-adhesive concave portion 10a of the peak 10 is shown in FIG.
As shown in FIG. 5, the height is slightly lower than the height of the flat flange upper surface 6a, for example, about 1.5 mm lower. The inner ridge 10b is formed higher than the height of the flange upper surface 6a, for example, about 2 mm higher. The outer ridge 10c is formed flush with the flange upper surface 6a.

As shown in FIGS. 1 and 2, the lid 2 has a printed layer 13 formed on the surface of a paper or synthetic resin base material 12 and an aluminum foil or silica vapor deposited on the back surface of the base material 12. A flexible laminated sheet formed by sequentially laminating the waterproof layer 14 and the heat-sealing resin layer 15 is formed in a square sheet shape having a size to close the upper end opening of the container body 1.

As shown in FIG. 1, the lid 2 has an outer end 2 of a portion (a hot water groove covering portion) 21 corresponding to an upper portion of the hot water draining portion 7.
1a, a separating line 16 formed of a perforation is formed on the left end 2
1b to the right end 21c. Also, at a location which enters inside by a predetermined width b from the outer end 22a of the hot water injection side location 22 opposite to the hot water drainer 7 of the lid 2,
A separation line 17 made of perforations is formed from the left end 22b to the right end 22c of the hot water injection side location 22.

The separation lines 16 and 17 formed by perforations are put in the base material 12 in advance of laminating the waterproof layer 14 on the base material 12 of the lid 2 and the waterproof layer 14 is laminated as shown in FIG. By doing so, the waterproof layer 14 side end of the perforated fine holes 16a, 17a of the separation lines 16, 17 is formed to be closed. Since the waterproof layer 14 is extremely thin compared to the thickness of the base material 12, even if the waterproof layer 14 is not perforated, it does not hinder the separation of the portion.

As shown in FIG. 1, a knob 18 is formed on the left end 21b of the lid 2 on the separation start side for separating the hot water groove cover 21 along the separation line 16. In addition, a handle portion 19 is formed so as to protrude at a right end portion 22c of the lid 2 on the separation start side for separating the hot water injection side portion 22 along the separation line 17.

In order to attach the lid 2 to the container body 1 in a sealed state, first, an instant food 30 (see FIG. 3) such as instant noodles, fried noodle sauce in a bag, sprinkle in a bag, etc. is stored in the container body 1. Then, the lid 2 is placed horizontally on the flange 6 of the container body 1 and a 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 upper surface 6a via the heat-sealing resin layer 15. At this time, the lid 2 has its separating line 16 passing perpendicularly above the middle of the hot water ditch 9 in the inward and outward direction of the flange, and the crest 10
Is releasably adhered to the flange upper surface 6a of the container body 1 so as to pass above the inner mountain portion 10.

The lid 2 is simultaneously heat-sealed to the inner ridge 10b and the outer ridge 10c of the ridge 10, but the heating press presses the entire circumference of the upper surface of the lid 2 from above with uniform pressure. Pressure, so that the inner ridge 10b is higher than the flange upper surface 6a.
Strength and outer ridge 10c flush with flange upper surface 6a
There is a difference in adhesive strength between the first and second inner ridges 10b, and the lower and outer ridges 10c have lower adhesive strength. However, the non-adhesive concave portion 1 depressed between the inner mountain portion 10b and the outer mountain portion 10c.
Since a gap is formed between Oa and the lid 2, it is not thermally fused.

When the lid 2 is heat-sealed with a hot press,
As shown in FIG. 10, the back surface of the flange 6 of the container body 1 is received and supported by a metal rectangular seal bucket B. In this case, not the entire back surface of the flange 6 but FIG.
As shown by an alternate long and two short dashes line, the upper end of the seal bucket B is received and supported in a concave portion 19 formed on the back surface side of the outer ridge portion 10c lower than the inner ridge portion 10b. As a result, the heating press causes the lid 2 to move the inner ridge 1 more than the pressure applied to the upper surface 6a of the flange 6 and the outer ridge 10c.
0b can be strongly pressurized. In addition, by adopting such a support form that the upper end of the seal bucket B is fitted only to the back side of the outer ridge 10c, the seal bucket B is more sealed than a complex-shaped seal bucket that receives over the entire back surface of the flange 6. The bucket B can be made simple and thin, and the seal bucket B can be manufactured inexpensively.

In the container having the above-mentioned configuration, when eating the stored food 30 such as instant yakisoba stored in the container,
First, grasp the knob 19 of the lid 2 and place the hot water injection side 2
2 along the separating line 17 while cutting the flange upper surface 6
Remove from a. At this time, if a bagged yakisoba sauce, a bagged sprinkle, etc. are contained, they are once taken out, hot water is injected from the corresponding portion of the container body 1, and the hot water injection side portion 22 from which the lid 2 is peeled off. Again on the container body 2 and wait for several minutes. Then, the stored food 30 such as instant yakisoba is absorbed and restored. In this case, the hot water groove 9
Is closed by a closing wall 11 and its upper part is completely covered by a lid 2, so that even if the container is almost full or the container is slightly tilted, the hot water can be drained from the hot water ditch. 9
From the outside to the outside.

After that, the knob 18 of the lid 2 is gripped and the hot water groove cover 21 is cut off along the separation line 16 and peeled off from the upper surface 6a of the flange. At this time, since the non-adhesion concave portion 10a which does not adhere to the inner surface of the drain groove cover 21 of the lid 2 is formed at the intermediate portion of the flange portion 10 on the flange upper surface 6a in the inward and outward direction of the flange, The groove cover 21 can be easily peeled off. The outer ridge 10c of the ridge 10 is formed flush with the upper surface 6a of the flange and is formed lower than the inner ridge 10b. The adhesive force between the outer ridge 10c and the inner surface of the hot water groove cover 21 is equal to that of the inner ridge 10b. If the adhesive strength with the lid 2 is weaker, the drain groove covering portion 21 can be easily formed with a smaller peeling force.
Can be peeled off.

When the hot water groove cover 21 of the lid 2 is completely cut off along the separation line 16 as described above, the separation line 16 crosses the upper part of the middle of the hot water groove 9 inside and outside the flange at right angles. As shown in FIG. 11, only the outer end of the hot water groove 9 in the inner and outer directions of the flange is exposed to the outside, and the upper part of the inner surface of the hot water groove 9 in the inner and outer directions of the flange, as shown in FIG. Is covered with the cut-off end 23 of the lid 2 which is left unpeeled on the container body 1 to obtain an unsealed state. Therefore, in this opened state, when the entire container body 1 is tilted so that the hot water draining portion 7 is at the bottom, the hot water in the container main body 1 is discharged to the outside from the hot water draining groove 9. The food 30 can be prevented from flowing out of the hot water ditch 9.

At this time, the separation line 16 of the lid 2 is
When the hot water drain groove cover 21 is cut off along the separation line 16 and opened, the inner surface of the separation end 23 of the lid 2 left on the container body 1 is formed with the inner mountain portion 10b. Since the bonded state is maintained, the separated end portion 23 reliably retains the state in which the upper part of the hot water groove 9 above the middle portion in the inward and outward directions of the flange is covered. Therefore, the lid 2
Is not lifted up from the inner mountain portion 10b, and the effect of preventing the stored food 30 such as fried noodles from flowing out of the hot water groove 9 is enhanced. Also, at that time, Uchiyama 1
0b is formed higher than the upper surface 6a of the flange to enhance the adhesive force with the inner surface of the lid 2, so that when the hot water is removed,
This also eliminates the possibility that the adhesive portion between the inner surface and the inner hill portion 10b may be peeled off, thereby contributing to an increase in the effect of preventing the outflow of the stored food 30 such as fried noodles. As shown in the illustrated example, if a large number of hot water grooves 9 are arranged in a row along substantially the entire length of one side 62 of the rectangular flange 6 in the circumferential direction, the hot water can be drained very quickly.

The container body 1 is not limited to a rectangular or other polygonal shape in plan view, but can be similarly applied to a circular shape in plan view as shown in FIG. Of course, in this case as well, in the same manner as in the above embodiment, the drain groove 9 and the crest portion 10 are provided on a part of the outer periphery of the flange 6 at the circular opening edge of the container body 1, while the drain groove of the lid 2 is provided. A separating line 16 is provided on the cover 21.

As a means for bonding the lid 2 to the container body 1, instead of the heat fusion in the above-mentioned embodiment, a bonding agent having food safety may 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 omit the closing wall 11, form the outside end of the hot water groove 9 in the flange inside and outside in an open shape, and close the portion with the lid 2. Leakage of hot water can be prevented.

It is also possible to provide only one hot water groove 9 and to provide ridges 10 on both sides of the hot water groove 9.
In the crest portion 10, it is preferable that the inner crest portion 10b is formed slightly higher than the flange upper surface 6a in order to increase the adhesive strength with the inner surface of the lid 2, but the present invention is not limited to this. The inner crest portion 10b has the same height as the flange upper surface 6a. It may be formed at the same time. The separation line 16 of the hot water groove cover 21 may be a tear tape or the like other than the perforation. The hot water injection side location 22 need only be peeled off from the upper surface 6a of the flange, and it is not always necessary to separate the hot water injection side location 22. Therefore, instead of providing the separation line 17, a simple indication line indicating the amount of the hot water injection side location 22 to be peeled is printed. It may be.

[0038]
