Description

  The present invention relates to a food cooking container suitable for steamed cooking.

Containers made of metal foil used for cooking food outdoors, such as barbecue parties, are commercially available.
As in Patent Document 1, such a food cooking container is formed by press-molding a metal foil with a rectangular bottom wall, a side wall rising from the periphery of the bottom wall, and a flange projecting outward from the upper edge of the side wall. It is formed integrally by doing. Moreover, since the outer edge of the flange is dangerous because the finger is cut when the cross section of the metal foil is exposed, edge winding is attached.
This type of food cooking container is placed on a barbecue stove via a grill or the like and used to cook fried dishes such as fried noodles, and is also used as a container for finished dishes.
Compared to the use of iron plates, it has become more popular in recent years because it has the advantage of being easy to handle because of its light weight, the advantage of being inexpensive because it is made of metal foil such as aluminum foil, and the advantage of being disposable. It's getting on.

By the way, this type of conventional food cooking container was suitable for fried cooking as described above, but because it opened upward, a large amount of steam escaped from the opening during cooking, It was not suitable for steamed cooking such as Hokkaido's famous Chanchanyaki.
Here, it is also conceivable to cover the opening of the container with an aluminum foil or a wrap film so that steam does not escape during cooking. However, in the outdoors, the aluminum foil or the like is easily blown off by the wind, and when an impact is applied by a person hitting the stove on which the food cooking container is placed during cooking, the aluminum foil or the like is easily removed from the opening.
Also, by using a pair of food cooking containers, put the other food cooking container upside down on one food cooking container placed on the barbecue stove, and overlap the flanges It is also conceivable to close the opening. However, since the upper and lower containers are not fixed to each other, the upper food cooking container is displaced by an impact or the like and the opening is easily exposed, as in the case where the aluminum foil or the like is placed on the opening.
Therefore, as long as a conventional food cooking container is used, in any case, a large amount of steam easily escapes from the opening, and it is difficult to maintain the state of steamed cooking.

  Therefore, the problem to be solved by the present invention is to provide a container formed of a metal foil suitable for steamed cooking.

In order to solve the above-described problems, the food cooking container of the present invention is integrally formed from a metal foil, respectively, a bottom wall, a peripheral wall rising from a peripheral edge of the bottom wall, and outward from an upper edge of the peripheral wall. A pair of flanges that extend over the outer edge of the flange and one or more tabs that can be folded back toward the upper surface of the flange starting from a foldable portion formed along the boundary with the flange. It consisted of a single container.
Then, when one of the pair of containers is turned upside down and placed on the other, and the tabs are folded back toward the top surface of the flange in a state where the flanges are overlapped with each other, the flanges of the one container are mutually connected. The container was held by being sandwiched from above and below by the flange and tab of the single container.
Here, the easy-folding part means a part that is physically or chemically processed so that it can be bent more easily than other parts of the container, and is not particularly limited. And perforations. The thin-walled portion may be a belt-like wide one, and in that case, a boundary portion between the other portion of the container alone and the thin-walled portion can be a starting point of bending.

A pair of upper and lower containers are overlapped so that the openings face each other, and a tab connected to the flange via a ruled line is folded, and the flange of the other container is sandwiched from above and below by the flange facing the tab. Thus, the single containers are fixed.
Therefore, even if an impact is applied, the single containers do not move relative to each other, and the state in which the opening is closed is maintained. For this reason, a large amount of steam does not escape to the outside during cooking, and steamed cooking can be suitably performed.

  Here, the flanges of the individual containers are provided with edge windings on almost the entire circumference except for the locations where they are connected to the tabs, and the easy-folding portions of the individual containers are arranged in parallel to the width direction of the flanges. Preferably, it consists of a plurality of parallel ruled lines.

In the case where the easy-folding portion of the single container is composed of a single ruled line or the like, the single ruled line or the like must be bent about 180 degrees when the tab is folded back so as to substantially overlap the upper surface of the flange. Therefore, the metal foil that is the material of the container itself may be torn from the bent part, and the tab may be separated from the container alone, or the finger may be cut if it touches the area where the cross section of the metal foil is exposed. there's a possibility that.
Therefore, as in the present invention, when each foldable portion is composed of a plurality of ruled lines, when the tab is folded back so as to substantially overlap the upper surface of the flange, the folding angle of each ruled line is set to about 90 degrees, for example, two. If it is three, it can be dispersed by about 60 degrees. Similarly, if there are x ruled lines, the folding angle can be about 180 / x degrees. Therefore, excessive bending at each ruled line is suppressed, and the metal foil can be prevented from being broken from the bent portion.

In addition, when an edge winding is attached to the flange outer edge of each container unit, this flange is a tab folded by folding the other container unit flange and an easy-to-bend portion composed of a single ruled line etc. about 180 degrees. Between the flange and the tab, almost no gap is formed. For this reason, there is a possibility that the edge winding is pressed by the flange and the tab from above and below and is crushed. If the edge winding, which is a thick portion provided on the outer edge of the single container, is crushed, the strength of the entire container may be reduced.
Therefore, as in the present invention, when the folding easy portion is composed of a plurality of ruled lines, and each ruled line is bent little by little so that the total folding angle is about 180 degrees, a certain distance is provided between the flange and the folded tab. A gap is formed. The edge winding attached to the flange of the other container body sandwiched between the flange and the tab has a certain outer diameter, but by entering this gap, it is suppressed from being crushed by pressing from above and below, and the entire container alone A reduction in strength is prevented.

From the above, it is preferable that each foldable part is composed of two parallel ruled lines, and the distance d between the ruled lines is approximately equal to or slightly larger than the outer diameter r of the edge winding.
When the tabs are folded back toward the upper surface of the flange by folding each ruled line about 90 degrees, a width capable of accommodating the edge winding attached to the flange of the other container unit is between the tab and the upper surface of the flange. A gap of about d is formed.

  Each of the tabs of the pair of containers is such that the flange does not interfere with each other when one of the containers is turned upside down and placed on the other and folded back toward the top surface of the flange with the flanges overlapped. It is preferable that they are connected to each other at the upper position.

  When configured in this manner, the tabs do not interfere with each other, so that the tabs can be easily folded back, and the tabs can be folded back to the position where they almost overlap the upper surface of the flange, so that the individual containers do not move. It can be firmly fixed to.

  Since this invention was comprised as mentioned above, it became possible to provide the metal foil shaping | molding container suitable for steaming baking cooking.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As shown in FIG. 1 to FIG. 4, the food cooking container according to the embodiment is composed of a single container 10 having a similar shape and used in a pair formed integrally from a metal foil by a press molding machine. Since it is a similar shape, it can manufacture with the same metal mold | die and can suppress manufacturing cost.

As shown in FIG. 1, each container unit 10 includes a bottom wall 11, a peripheral wall 12, a flange 13 to which an edge winding 13 a is attached, and a tab 14.
Although the kind of metal foil used for the container simple substance 10 is not specifically limited, Aluminum foil, copper foil, iron foil etc. can be illustrated and aluminum foil is preferable from being lightweight and cheap. The thickness of the metal foil is not particularly limited, but if it is less than 50 μm, the strength may be insufficient, and if it exceeds 300 μm, the material cost increases, so about 50 to 300 μm is preferable.

As shown in FIGS. 1A and 1B, the bottom wall 11 of the single container 10 has a shape in which four corners of a rectangle are cut into small right-angled isosceles triangles. The bottom wall 11 may be appropriately provided with a rib for reinforcement or may be provided with unevenness.
The shape of the bottom wall 11 of the container 10 is not limited to this embodiment, and may be a square, a circle, an ellipse, or the like.
The area of the bottom wall 11 is not particularly limited, but if the area is less than 25 cm ² , the dimensions are too small to make cooking work difficult, and if it exceeds 5000 cm ² , the strength of the container 10 is lowered and is likely to be deformed. Therefore, 25 to 5000 cm ² is preferable.

As shown in FIG. 1A, the peripheral wall 12 of the single container 10 rises from the peripheral edge of the bottom wall 11 and has a substantially uniform height.
The height of the peripheral wall 12 is not particularly limited, but if it is less than 10 mm, the depth of the container unit 10 becomes insufficient and it becomes difficult to store food, and if it exceeds 200 mm, it is bulky and difficult to carry. preferable.

As shown in FIGS. 1 (a) and 1 (b), the flange 13 of the single container 10 projects substantially horizontally outward from the upper edge of the peripheral wall 12, and the width thereof is uniform. The width of the flange 13 is not particularly limited.
A rib 12a that extends vertically along the peripheral wall 12 from the peripheral wall 12 to the flange 13 of the container unit 10 and then bends and extends horizontally along the flange 13 is formed on almost the entire circumference except for the corners. It has been reinforced. Such ribs 12a can be omitted as appropriate.

As shown in FIGS. 1 (a) and 1 (b), the tab 14 is connected to only the outer edges of two corners located diagonally among the four corners of the flange 13 of the container 10 alone. Yes. The outer edge of the tab 14 has an arc shape so that it can be easily picked.
The boundary portion between the flange 13 and the tab 14, that is, the base of the tab 14 is an easily foldable portion that is easier to bend than other portions. Here, as shown in FIGS. 1A, 1B, and 2, the easy-to-bend portion is formed from two substantially parallel ruled lines parallel to the width direction of the flange 13, that is, the direction from the inside to the outside of the container unit 10. It is configured.

An edge winding 13a that is curled upward in a cylindrical shape is formed on almost the entire circumference except for the portion where the tabs 14 on the outer edge of the flange 13 are continuously provided. This edge winding 13a can be omitted.
Here, the distance d between the two ruled lines 14a constituting the easy-to-bend portion is set to be substantially the same as or slightly larger than the outer diameter r of the edge winding 13a. Specifically, for example, it is designed to be about r−2 ≦ d ≦ r + 5 (mm).

When using the food cooking container of the embodiment, as shown in FIG. 3 and FIG. 4, one container unit 10 containing the food F is placed on the stove R and the other is turned upside down. The container unit 10 is covered as a lid, and the flanges 13 of the unit containers 10 are overlapped with each other with the openings facing each other.
The container 10 is in a state in which one opening is closed with the other, and a closed space containing the food F is formed inside the food cooking container.
Therefore, a large amount of steam rising from the food F by heating is prevented from escaping to the outside of the food cooking container, and it is easy to cook steamed food. Note that a small amount of steam leaks from a slight gap naturally formed between the flanges 13 of the stacked container 10, thereby preventing an increase in internal pressure.

In this state, as shown in FIG. 3B, the parallel ruled lines 14a are bent by about 90 degrees, and the tabs 14 are almost overlapped with the upper surface of the flange 13 (so as to be substantially parallel with a slight gap). Fold back.
Here, if similar containers with two tabs on the diagonal line are overlapped with each other in a state where one of the two is inverted upside down with respect to the other, the tabs of the two containers 10 are shifted to a position where they do not interfere with each other. The above folding operation can be performed smoothly.
As a result, the container unit 10 is in a state in which one flange 13 is sandwiched between the other flange 13 and the folded tab 14 so that the container unit 10 moves and the opening does not open and steam does not escape. So that it will be firmly fixed.

When the tab 14 is folded back, the two ruled lines 14a are each bent by about 90 degrees, so that the folding angle is distributed compared to the case where the single ruled line 14a is bent by about 180 degrees, Is hard to tear.
Further, since the distance d between the two ruled lines 14a is substantially the same as the outer diameter r of the edge winding 13a as described above, when the tab 14 is folded, the tab 14 and the flange 13 of one container unit 10 are The upper and lower widths of the gap formed between the two are about d, and the edge winding 13a attached to the flange 13 of the other container unit 10 is accommodated almost without excess or deficiency.
Accordingly, the edge winding 13a is crushed by the tab 14 and the flange 13 to reduce the strength of the container unit 10 or the gap between the tab 14 and the flange 13 is too large compared to the outer diameter of the edge winding 13a. It is prevented from wobbling.

  It should be considered that the embodiments disclosed herein are illustrative and non-restrictive in every respect. The scope of the present invention is defined by the terms of the claims, and is intended to include any modifications and variations within the scope and meaning equivalent to the terms of the claims.

For example, in the above-described embodiment, the pair of container units 10 have a similar shape. However, when the tabs 14 of one container unit 10 are folded toward the upper surface of the flange 13 when they are overlapped in an inverted state, the tabs 14 and the flanges are overlapped. As long as the flange 13 of the other container unit 10 can be sandwiched and held by 13, the shape may not be similar.
For example, the single container 10 placed on a stove or the like may be a deep bottom, and the single container 10 covered as a lid may be a shallow bottom.

Moreover, in the said embodiment, although the two tabs 14 are provided in each container single-piece | unit 10, it is not limited to this. For example, one tab 14 may be provided for each container unit 10, or the number of tabs 14 may be different for one container unit 10 and the other container unit 10.
Further, the position of the tab 14 is not particularly limited to the corner portion as in the embodiment as long as it is on the outer edge of the flange 13. For example, when the shape of the bottom wall 11 of the container unit 10 is substantially rectangular, one container unit 10 is provided with a tab 14 on the outer edge of the flange 13 on the middle point of the long side of the bottom wall 11, and the other unit container unit 10. 10, a tab 14 may be provided on the outer edge of the flange 13 on the intermediate point of the short side of the bottom wall 11.
The shape of the tab 14 is not limited to that of the embodiment, and may be a polygon, for example. The tab 14 may or may not be formed with an edge winding.

The ruled lines 14a constituting the easy-to-bend portion are not limited to two as in the embodiment, but may be three or more or one.
When the flange 13 is not attached to the flange 13, it is not necessary to form a gap that can accommodate the edge winding 13 a between the tab 14 and the flange 13 of another container 10 that sandwiches the flange 13. The structure can be simplified by using one ruled line 14a.
When the number of ruled lines 14a is three, the folding angle of each ruled line 14a may be about 60 degrees, and when the number of ruled lines 14a is four, the folding angle of each ruled line 14a may be about 45 degrees. Of course, the folding angle of each ruled line 14a does not need to be uniform. For example, in the case of three lines, the folding angle of two of them may be about 90 degrees, and the remaining folding angle may be about 0 degrees. .
In any case, when there are three or more ruled lines 14a, the distance d between the innermost ruled line 14a and the outermost ruled line 14a in the width direction of the flange 13 is designed to be larger than the outer diameter r of the edge winding. preferable. If designed in this way, the folding angle of each ruled line 14a is appropriately adjusted within the range of the total folding angle of about 180 degrees, so that the other side between the tab 14 and the flange 13 which are folded back by the folding and opposed to each other. It becomes possible to form a gap having a width that can be accommodated without the edge winding 13a of the flange 13 of the single container 10 being crushed.

  Although the container for food cooking of embodiment assumes the thing of a comparatively big size which is mainly used when cooking for a large number of people outdoors, it cooks with a gas stove at home. It is also possible to apply to a relatively small size such as a single meal size.
