Most of the conventional hot water cutting ports of this type of container with a hot water cutting function are provided with tongue pieces made of U-shaped cuts of European characters. That is, the container main body is provided with a flange having an upper surface opened and projecting outward from the entire circumference of the upper edge of the opening, and includes a peripheral wall that covers the opening of the container main body so as to be opened and closed and covers the flange flange. The cover is formed by a sheet-molded lid provided with a plurality of hot water outlets and at least one vent hole at the edge.
JP 2000-21927 A JP 2003-29200 A Japanese Utility Model Publication No. 07-17776 JP-A-11-165770

In such conventional means, when applied to the contents such as thin noodles and vermicelli that are the subject of the present invention, the hot water outlet and the inside of the container body are directly connected. When the container body is tilted, both the hot water and the contents rush into the hot water outlet, and the contents are discharged together with the hot water.

So, I tried to adopt a technique to make the hot water cut-out hole small so that the contents are not discharged, but this time the content of the hot water cut-off is blocked, causing clogging and making it impossible to cut the hot water. A new problem has occurred.

Furthermore, apart from the above-mentioned problems, this type of conventional packaging container may be deformed by hot water for cooking because the lid is made thin by sheet molding. In addition, in order to prevent inadvertent detachment of the lid, it is difficult to open the lid because it includes an engagement rib that engages the edge of the container, that is, the flange, around the entire circumference of the lid. There is also a problem.

In view of the above problems, the present inventor has started to develop a packaging container that can handle contents such as fine noodles and vermicelli.
First of all, regarding clogging problems, do not carry contents such as fine noodles or vermicelli (hereinafter simply referred to as “content”) directly to the hot water outlet, and prevent further flow down before the hot water outlet. As a result, generally good results were obtained. In addition, the problem that the lid is deformed by hot water can be satisfied from the empirical rule that the deformation can be reduced by providing irregularities, and the difficulty of opening the lid is also a number of experiments. From the results, it was found that the conventional technical common sense was not reliable, and this point was also solved successfully with an innovative structure, and is proposed here.

Therefore, the object of the present invention is that the opening area of the hot water outlet can be made as large as that of the conventional one, but the discharge of the content can be eliminated and the clogging can be solved well, and the hot water is reduced. The object of the present invention is to provide a packaging container having a lid that can improve the pouring speed and the pouring ability, and is sturdy and easy to open.

In order to solve the above technical problem, a packaging container according to claim 1 of the present invention has a container main body provided with a flange having an upper surface opened and projecting outward from the entire periphery of the upper edge of the opening. The opening of the container body is closed so that it can be opened and closed, and has a peripheral wall that covers the flange,
In a packaging container comprising a plurality of hot water cutouts at the edge and a lid formed with at least one air vent and formed into a sheet, a plurality of hot water cut grooves recessed inward and outward in the opening of the container body On the other hand, the lid is provided with a plurality of hot water outlets each provided with a tongue piece that can be opened and closed oppositely on the hot water groove, and inside the lid of the hot water outlet from the groove bottom of the hot water groove. Further, a rib that is recessed into the bottom of the container body is formed, and a hot water outflow gap of a predetermined size is formed between the outer end surface of the rib and the inside of the container of the hot water cut groove. .

According to the configuration as described above, the rib that is recessed further toward the bottom of the container body than the groove bottom of the hot water cut groove is provided inside the lid of the hot water cut opening, and the outer end of the rib and the hot water cut groove By forming a hot water outflow gap of a certain size between the inside of the container, the softly disassembled contents are blocked by the outflow gap when the hot water is discharged, and the hot water is poured together with the hot water. Flooding to the cut is suppressed, and the flow of contents to the hot water cut groove side is reduced as much as possible. Therefore, the contents are difficult to move into the space between the hot water cut groove and the lid, and therefore the hot water cut opening is not clogged,
Enables quick drainage of hot water. In addition, since the hot water cut opening provided in the lid is opened corresponding to the hot water cut groove, the hot water flowing down the hot water cut groove can be moved outside the cover without obstructing the flow. It drains straight, and the hot water draining speed and hot water drainability are improved especially when the hot water is low.

In addition, by providing a plurality of ribs that are recessed further toward the bottom of the container body than the bottom of the hot water cut groove at the center of the lid of the hot water cut opening, a bank is formed at the lid portion between the ribs. Will lead to increased lid strength.

Therefore, this invention has the following effects.
The packaging container according to claim 1 of the present invention has a plurality of ribs that are recessed further toward the bottom side of the container body than the bottom of the groove of the hot water cut groove so as to correspond to the hot water cut openings inside the lid from the hot water cut opening. Since an outflow gap of a predetermined size of hot water is formed between the outer end face of these ribs and the inside of the container of the hot water cut groove, the opening area of the hot water cut opening is made as large as before. Even if the hot water can be drained much more quickly, there is little risk of the contents leaking out of the container during the hot water draining operation, clogging can be eliminated well, and the hot water draining can be performed quickly, The remaining hot water can be eliminated well, and the contents can be eaten more deliciously.

Moreover, since the levee obtained by providing ribs corresponding to the hot water cutting grooves increases the strength of the lid, cooking by pouring hot water due to the presence of this plurality of dams and the subsequent discharge of hot water,
It is possible to successfully prevent the unexpected situation that the lid is deformed.

In the above configuration, according to the present invention, as described in claim 2, the peripheral wall of the lid is provided with a lateral rib that engages with the flange of the container body except for a predetermined size range around the position where the vent is present. It is desirable that a vertical rib is provided corresponding to the position of the vent.
In the vicinity of the position where the vent is present, the engagement between the lid and the container body by the lateral rib is eliminated, and a slight gap is formed between the flange and the peripheral wall of the container body by the longitudinal rib. This is because it is possible to reduce the buckling of the water and to easily open the seal, and also to ensure good air permeability even in a situation where the hot water outlet is filled with discharged hot water, and to ensure the hot water cutting speed and hot water performance.

Example 1
First, when the packaging container according to the present invention is applied to a rectangular container for hot water draining vermicelli,
This will be specifically described below with reference to FIGS.

As shown in FIGS. 4, 5, 9, and 10, the packaging container 1 includes a container body 3 having a rectangular shape or a square shape (square shape in the illustrated example) and an upper surface being opened 2, and the container body 3. Upper edge 4 of opening 2
A flange 5 projecting outward from the entire circumference, and a lid having a rectangular shape that closes the opening 2 of the container body 3 so as to be openable and closable, including the flange 5 and having substantially the same shape as the container body 3 6.

As shown in FIGS. 2, 4, and 6 to 8, the lid 6 is integrally and continuously suspended downward from a flange portion 61 that is fitted to the flange 5 of the container body 3 from above and from the outer peripheral edge of the flange portion 61. The
A fitting flange portion 6 fitted to the flange 5 of the container body 3 by a hanging portion 62 serving as a peripheral wall.
A is formed, and is configured to be detachably opened and closed with respect to the container body 3.

As shown in FIGS. 4, 5, 9, and 10, the lid 6 includes a plurality of U-shaped cuts that are surrounded by U-shaped cuts on the flange portion 61 of one corner portion 63 located on the diagonal line. A plurality of claw pieces 7 are provided, and a plurality of (three in the illustrated example) openings formed by raising the claw pieces 7 upward are used as the hot water cut-off openings 8 (see FIG. 2). Further, on the flange portion 61 of the other corner portion 64, there is provided one claw piece 9 having a size obtained by combining the two claw pieces 7 and surrounded by a U-shaped cut line of European characters. In addition, an opening formed by raising the nail piece 9 upward is used as the vent 10 (see FIG. 8).

In addition, as shown in FIGS. 1 to 5, inside the lids of the plurality of hot water cutouts 8, each has a predetermined interval corresponding to each hot water cutout 8, that is, the same dimension as the interval of the hot water cutouts 8. Ribs 11 are provided that open and are deeply recessed downward. Therefore, a convex bank 12 is formed between the ribs 11. Further, on the inner side of the lid of the vent hole 10, as shown in FIG. 7, one protrusion in a direction along a virtual diagonal line connecting the hot water cut-out opening 8 and the vent hole 10 is formed corresponding to the vent hole 10. Ribs 13 are provided.

On the flange portion 61 of the pair of corner portions 65 positioned on the other diagonal line of the lid 6, as shown in FIGS. 4 to 7, the corner portion 65 is sandwiched over a predetermined size range, that is, in a plan view, Two ridges 14 inside and outside are integrally formed in an L shape of the character. In order to prevent the lid 6 from opening during hot water cutting, the thumb and the lid 6
The contact area is reduced, and the amount of heat transferred from the ridges 14 to the thumb is reduced to reduce the heat.

Further, in providing the bank 12 and the convex rib 13, in this embodiment, as shown in FIGS. 4 and 5, an annular recess 15 is provided leaving the center and periphery of the lid 6, and this recess 15 is used. Yes. In other words, the concave portion 15 is formed by leaving a large circular plateau portion 16 at the center and the flange portion 61, and the stepped portion 15 is formed between the plateau portion 16 and the flange portion 61.
The bottom of the recess 15 is lifted up to a level substantially the same as that of the plateau 16 and the flange 61 to form a weir in the groove. Incidentally, in this embodiment, the depth of the rib 11 is set to the same height level as the bottom of the recess 15. The plateau 16 is suitable for printing because the surface is formed flat.

Further, as shown in FIGS. 1, 2, and 6 to 8, a lateral rib 66 that engages with the edge of the flange 5 of the container body 3 is provided on the hanging portion 62 that becomes the peripheral wall of the lid 6. In particular, there is a feature in the place to be provided. Specifically, first, without providing the entire circumference as in the prior art, the corner 63 provided with the hot water cut opening 8 and the protruding strips 14 at both corners sandwiching the corner 63 are provided. It is provided so as not to be provided in the other corner 64 provided with the vent 10, although it is provided intermittently or in a series over the provided corner 65. This is because the lid 6 can be easily removed from the container body 3.

As shown in FIGS. 5 and 8, vertical ribs 67 are provided at positions corresponding to the vent holes 10 of the peripheral wall 16. The vertical rib 67 is formed so as to be recessed in a semicircular shape from the outside to the inside of the peripheral wall 16. Therefore, when the container body 3 is covered with the lid 6, the flange 5
The inner surface of the vertical rib 67 comes into contact with the outer peripheral edge of the cover 6 so as to facilitate the opening of the lid 6. In addition, since a slight gap S is formed between the outer peripheral edge of the flange 5 and the peripheral wall 16, this gap S also functions as an air inlet, and the hot water cut opening 8 is closed with hot water when hot water is cut. Even at times, in cooperation with the vent 10, air permeability is ensured, and the hot water draining speed and hot water drainability are well secured.

In the conventional method, the engagement rib is provided over the entire circumference of the hanging part, and it takes a considerable force to open the lid 6 and it is difficult to open it. Even if there are no lateral ribs for engagement at one corner, the lid fits in exactly the same way as if the ribs were provided on the entire circumference. I understood that From this experimental result, the lid 6 can be easily opened by omitting the horizontal rib at one corner.

Further, the presence of the convex rib 13 picks up and lifts the other corner portion 64 not provided with the lateral rib 66 when the lid 6 is opened, so that a large bending stress is applied to the corner portion 64 and the inside thereof. Therefore, the structure is the result of increasing the strength so as to compete well with this, the lid 6 can be opened firmly and lightly, and the ventilation of the vent 10 is also ensured accurately. The

Further, by the hot water poured into the container body 2 and when the hot water is discharged, the periphery of the hot water outlet 8 and further the lid 6
The whole deformation of is feared. However, due to the presence of the bank 12, the lid 6, particularly the hot water outlet 8
Since unevenness is formed in the vicinity of the hot water outlet and the strength of the hot water cut opening 8 is increased, there is no risk that the lid 6 will be inadvertently deformed by the heat of the hot water poured, and the hot water can be cut safely. Also,
Needless to say, the increase in the strength of the lid 6 also greatly contributes to the convex ribs 13 and the plateau 16.

As shown in FIGS. 4, 9, and 10, the container body 3 is formed so as to spread upward with a foamed resin material such as foamed polystyrene, and the corner corner 17 and the vent hole 1 corresponding to the hot water cutout 8 of the lid 6.
A shallow portion 19 is integrally formed inside each corner 18 corresponding to zero.

The concrete structure of the shallow portion 19 is such that the peripheral wall 3A of the container body 3 is positioned at a position one step lower than the flange 5 of the container body 3 at the corners 17 and 18 of the container body 3 as the upper end. It is formed as a step portion bulged from 20 toward the inside of the container body 3 in sequence.

The rising inner wall surface 19A of this stepped portion continuously exists in a smooth circular arc with the inner surface of the peripheral wall 3A of the container body 3 that is continuous to the left and right of the corners 17 and 18. That is, the stand-up inner wall surface 19A is a flat vertical surface, and does not adopt an independent form in which the rising inner wall surface 19A is connected to the inner surface of the peripheral wall 3A of the container body 3 connected to the left and right sides with an angle.

Furthermore, on the upper surface 19B of the shallow portion 19, as shown in FIGS. 1, 2, and 9-12, the flange 5 is directed inward of the container body 3, that is, inward and outward of the container body 3, and the rising inside A plurality of ridges are integrally raised over almost the entire length up to the wall surface 19 </ b> A to form a weir 21, and a concave groove between these weirs 21 is used as a hot water cut groove 22. Further, the upper surface of the weir 21 is provided slightly below the upper surface of the flange 5.

4, 9, 10, and 12, a portion indicated by a reference numeral 24 is a step portion projecting inwardly on the inner peripheral surface near the opening 2 of the container body 3, and serves as an index of the amount of pouring.

An even more important point is the relative relationship between the hot water cut groove 22 and the rib 11 provided on the lid 6.
Specifically, as shown in FIGS. 1 and 2, the rib 11 has a bottom 22 </ b> A of the hot water cut groove 22.
Further, the container body 3 is recessed to the bottom 20 side. In the example of the figure, the rib 11 is recessed with a depth twice the depth of the hot water cut groove 22, and the bottom 11 </ b> A of the rib 11 is located far from the bottom 22 </ b> A of the hot water cut groove 22 on the bottom 20 side of the container body 3. become. Further, as shown in FIG. 3, a slight gap 23 is formed between the outer end surface 11B of the container body 3 of the rib 11 and the rising inner wall surface 19A of the shallow portion 19, so It is configured to be used as an outflow gap.
The interval of the gap 23 is set such that vermicelli can not flow down to the hot water outlet 8 side with hot water when the hot water is cut.

In addition, the structure called between the outer side end surface 11B of the container main body 3 of the rib 11 and the rising inner wall surface 19A of the shallow portion 19 is the outer end surface of the rib according to claim 1 and the hot water cut groove. The subordinate concept of the structure expressed between the inside of a container is represented.
In the example shown in the figure, a shallow portion 19 is provided, and a hot water cut groove 22 is provided here. However, without providing the shallow portion 19, the flange 5 of the container body 3 is provided with irregularities to provide a hot water cut groove. It is because it can also be. In this case, the gap 23 is formed between the rising wall 3 </ b> A of the container body 3 and the outer end surface 11 </ b> B of the rib 11.

Further, as shown in FIG. 2, the dike 12 adjacent to the hot water cut opening 8 is divided into the hot water cut grooves 22.
The weirs 21 adjacent to each other and the container body 3 are arranged to face each other in the inner and outer directions.

Therefore, as shown in FIGS. 1 and 3, the rib 11 stands on the inner end of the container main body 3 of the hot water cut groove 22 so as to cover the inlet, and as shown in FIG. 2
2 and the weir 21 forming the cover 6 will stand so as to cover the outer end of the container body 3 of the bank 12 of the lid 6, and as a result, the flow of vermicelli to the hot water cutout 8 is via a limited-size bottleneck. It has a structure that can only flow down. As a result, the vermicelli cannot easily flow down to the hot water outlet 8 side together with the hot water at the time of hot water cutting. Therefore, while the opening area of the hot water cut opening 8 can be made as large as before, the drainage of vermicelli can be eliminated well, and the clogging of the hot water cut opening 8 can be solved well, and the hot water speed when the hot water is reduced. Thus, the packaging container 1 having the lid 6 that can improve the heat dissipation property and is sturdy and easy to open is obtained.

1, 2, 5, and 8, the structure indicated by reference numeral 25 is a recessed groove provided on the base side of the claw piece 7 for opening the hot water cutout 8 and the claw piece 9 for opening the vent 10. This is for facilitating rising for opening the respective nail pieces 7 and 9.

Furthermore, as the container body 3, a molded heat insulating material is used, for example, a thickness of 10 m.
An expanded polystyrene sheet of about m can be obtained by a vacuum forming method. Further, for example, a paper container is obtained by adhering and fixing a heat insulating sheet in which a heat insulating material with a single-side embossed liner paper is attached to the outer surface of a paper cup body including a paper side wall and a paper bottom wall. What was used as the main body 3 etc. can also be used.

A method of using the packaging container 1 shown in the above embodiment will be described below.
First, after opening the lid 6 of the container body 3 and pouring hot water, the engagement rib 66 of the lid 6 is again engaged with the edge of the flange 5 of the container body 3 to close the lid 6. In this state, after a predetermined time has elapsed, that is, after the vermicelli has been dissolved in hot water, the ridge 14 of the lid 6 and the outer surface of the bottom 20 of the container body 3 are sandwiched by a plurality of fingers of the left and right hands, The entire container 1 is inclined at an angle, and the hot water in the container body 3 is discharged from the hot water outlet 8 to perform the hot water cutting. Next, the lid 6 is opened again after the hot water is cut off, and the seasoning is added to the vermicelli after cooking in the container body 3 to finish.

By the way, when the hot water is cut off, the hot water discharge flow path leading to the hot water cut opening 8 is very narrow as described above, that is, the gap 23 formed by the rib 11 and the weir 21 standing in front of the bank 12. Due to the presence of water, there is little risk that this will inadvertently flow down with the hot water into the hot water outlet 8 even if it is much thinner than conventional thick noodles such as fried noodles and ramen. Is done. Therefore, there is little risk of clogging at the hot water outlet 8, and the hot water can be quickly discharged and the remaining hot water can be eliminated well, so that the vermicelli can be eaten more deliciously.

Moreover, a vertical rib 67 is provided at a location corresponding to the vent 10 on the side opposite to the side where the hot water cut opening 8 of the hanging portion 62 which is the peripheral wall of the lid 6 is provided, and the corner portion 63 provided with the hot water cut opening 8 is sandwiched between the vertical portion 67. Since the lateral ribs 66 are provided intermittently or continuously over the corners 65 where the convex strips 14 are provided at both corners, the lid 6 can be easily removed from the container body 3. In addition, since a slight gap S is formed between the outer peripheral edge of the flange 5 and the peripheral wall 16, this gap S also functions as an air inlet, and the hot water cut opening 8 is closed with hot water when hot water is cut. Even now, in cooperation with the vent 10, air permeability can be secured, and the hot water cutting speed and hot water performance can be well secured.

The use of the container of the present invention is not limited to instant vermicelli packaging, but is packaged such as dried vegetables and seaweeds that have been reconstituted in hot water, and further processed by washing in water. It can also be used for packaging such as tazaru soba.
