Description

[Technical Field]

[0001] The present invention relates to a cooking container including a container body having an opening at the top end and a lid placed on the top end of the container body to close the opening. [Background technology]

[0002] Conventionally, known heating and cooking containers that have a container body with an opening and a lid that covers the opening of the container body include the resin tableware described in Patent Document 1 and the reheating container described in Patent Document 2.

[0003] The resin tableware in Document 1 is intended to reheat fried foods and other oily dishes using hot air without damaging their appearance or texture, and specifically comprises a container body with an opening on the top surface, a lid body that covers the opening, and a mounting part that is accommodated in the container body so that a gap is formed between the container body and the lid body, with the lid body covering the opening and a support part that supports the lid body.

[0004] Furthermore, the reheating container in Document 2 aims to solve the problem that when reheating refrigerated or frozen food, conventional reheating containers do not heat the food evenly, and heating for a long period of time is required to heat the entire food. This reheating container aims to solve the problem of moisture evaporating from the food and drying out the food, and specifically, it consists of a main container that is box-shaped and open at the top, with a brim around the bottom edge, and a box-shaped lid that is open at the bottom, with a side that abuts against the brim when placed over the main container. An insulating space is formed between the side of the main container and the side of the lid, and the main container and the lid are configured to abut at two points, and the side of the main container is configured so that the wall thickness increases from the top end to the bottom end.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-029399 [Patent Document 2] Japanese Patent Application Laid-Open No. 2009-100822 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the above-mentioned conventional cooking containers (resin tableware, reheating containers) have the following problems.

[0007] First, although the basic components include a container body and a lid, additional elements are required, such as a separate mounting section made of metal or a specially shaped lid that is roughly the same size as the container, which results in a lack of structural simplicity. This results in increased costs and reduced productivity in terms of materials and manufacturing, as well as poor ease of cleaning and storage.

[0008] Secondly, the overall design is complicated, making it difficult to use as tableware. In other words, creating a product that can serve as both a cooking container and tableware is desirable from the perspective of increasing multi-functionality and versatility, but conventional products have focused on cooking as their main function, and tableware function has been a secondary function or not even planned, making it difficult to fully utilize both functions.

[0009] SUMMARY OF THE INVENTION An object of the present invention is to provide a cooking container that solves the problems present in the background art. [Means for solving the problem]

[0010] In order to solve the above-mentioned problems, the present invention provides a heating and cooking container 1 comprising a container body 2 having an opening 2o at its upper end 2u and a lid 3 that is placed on the upper end 2u of the container body 2 to close the opening 2o, the lid 3 having a plurality of engaging protrusions 4a, 4b... at its lower end 3f that are arranged at predetermined intervals and that abut against an inner wall surface 2i of the container body 2 to regulate its position, and a container body 2 in which, when the lid 3 is placed in a state offset in one direction Fs, the engaging protrusions 4b... located on the offset side are positioned externally, and the engaging protrusions 4c... at other positions are regulated by the inner wall surface 2i.

[0011] In this case, according to a preferred embodiment of the present invention, the lid 3 can be integrally molded from a predetermined material. In this case, it is desirable that the lid 3 be formed into a rectangular shape in plan view and have four engaging protrusions 4a, 4b, 4c, and 4d formed to predetermined lengths along the horizontal sides 3a and 3b and the vertical sides 3c and 3d. Meanwhile, the container body 2 can be integrally molded from a predetermined material. In this case, it is desirable that the container body 2 be formed into a rectangular shape in plan view and have inclined sides 2ac, 2cb, 2bd, and 2da of predetermined lengths connecting the horizontal sides 2a and 2b and the vertical sides 2c and 2d at the four corners 2s. [Effects of the Invention]

[0012] The cooking container 1 according to the present invention having such a configuration provides the following significant effects.

[0013] (1) The basic components are only the container body 2 and the lid 3, and no additional parts or special lids are required, so the container body 2 and the lid 3 can be made into a simple form (shape). This reduces costs in terms of materials and manufacturing, improves productivity, and allows the product to be offered at a low price. In addition, the product can be made easier to clean and store.

[0014] (2) The overall form (shape) is simple, and in particular, the container body 2 does not have any unnecessary additional elements, so it can function not only as a cooking container but also as a tableware, and the design and function of the container are sufficient. Therefore, it can be provided as a product with high added value and marketability, by fully ensuring the functions of both a cooking container and tableware and enhancing its multifunctionality and versatility.

[0015] (3) In a preferred embodiment, when forming the lid portion 3, if the entire lid portion 3 is molded as a single unit using a predetermined material, it can be molded as a single unit using a synthetic resin material or the like, by injection molding or the like, and therefore can be manufactured easily and at low cost, resulting in excellent mass productivity and low cost.

[0016] (4) In a preferred embodiment, when forming the lid portion 3, the entire planar shape is formed into a rectangular shape, and four engaging protrusions 4a, 4b, 4c, and 4d are formed to a predetermined length along the horizontal sides 3a and 3b and the vertical sides 3c and 3d. By combining this with the container body portion 2, offset displacement can be easily and reliably achieved, thereby improving usability (ease of use) and convenience.

[0017] (5) In a preferred embodiment, when forming the container body 2, if the entire body is molded integrally using a predetermined material, it can be molded integrally using a synthetic resin material or the like by injection molding or the like, which makes it easy to manufacture at low cost, and has excellent mass-producibility and low cost.

[0018] (6) In a preferred embodiment, when forming the container body 2, the entire planar shape is formed into a rectangular shape, and the four corner portions 2s... are formed with inclined side portions 2ac, 2cb, 2bd, 2da of a predetermined length connecting the horizontal side portions 2a, 2b and the vertical side portions 2c, 2d. By combining this with the lid portion 3, the lid portion 3 can be easily and reliably offset, thereby improving usability (ease of use) and convenience. [Brief explanation of the drawings]

[0020] Next, preferred embodiments of the present invention will be described in detail with reference to the drawings.

[0021] First, the configuration of a cooking container 1 according to this embodiment will be described with reference to FIGS. 1 to 6. FIG.

[0022] As shown in FIG. 1, the cooking container 1 basically comprises a container body 2 and a lid 3.

[0023] In this case, the entire container body 2 is integrally molded using a predetermined material Rm, such as a heat-resistant synthetic resin material, by injection molding, etc. In this way, when forming the container body 2, if the entire body is integrally molded using a predetermined material, it becomes possible to integrally mold using a synthetic resin material, etc. by injection molding, etc., which allows for easy and low-cost production, thereby improving mass productivity and cost reduction.

[0024] The container body 2 has a predetermined depth and is formed into a rectangular shape in plan view as a whole, as shown in Fig. 4. That is, it is formed with horizontal sides 2a and 2b that are long sides and vertical sides 2c and 2d that are short sides.

[0025] The planar shape of the illustrated container body 2 is approximately 200 mm in the horizontal direction, 140 mm in the vertical direction, and 25 mm in the depth direction. Also, as shown in Fig. 4, the four corners 2s are provided with inclined side portions 2ac, 2cb, 2bd, and 2da of a predetermined length (approximately 20 mm in the illustrated example) that connect the horizontal side portions 2a and 2b with the vertical side portions 2c and 2d. The inclined side portions 2ac in the illustrated example are angled approximately 45° relative to the respective side portions 2a and 2b.

[0026] On the other hand, the upper end 2u of the container body 2 forms a horizontal edge with an opening 2o, as shown in Figure 1. The container body 2 has four integrally formed legs 11 at its lower bottom surface.

[0027] In this way, when forming the container main body 2, the entire planar shape is formed into a rectangular shape, and the four corner portions 2s... are formed with inclined side portions 2ac, 2cb, 2bd, 2da of a predetermined length connecting the horizontal side portions 2a, 2b and the vertical side portions 2c, 2d.By combining this with the lid portion 3, the lid portion 3 can be easily and reliably offset, thereby improving usability (ease of use) and convenience.

[0028] On the other hand, the entire lid portion 3 is integrally molded by injection molding or the like using a predetermined material Rm, such as a heat-resistant synthetic resin material. In this way, when forming the lid portion 3, if the entire lid portion 3 is integrally molded from a predetermined material, it can be integrally molded by injection molding or the like using a synthetic resin material, etc., and therefore can be produced easily and at low cost, thereby improving mass productivity and cost reduction. The material from which the lid portion 3 is formed may be the same as that of the container body 2 described above, or it may be a different material.

[0029] The lid 3 has a predetermined height and is formed into a rectangular shape in plan view as shown in Fig. 3. That is, it is formed by horizontal sides 3a and 3b which are long sides and vertical sides 3c and 3d which are short sides.

[0030] The planar shape of the illustrated lid 3 is the same as that of the container body 2 described above, i.e., approximately 200 mm in the horizontal direction and 140 mm in the vertical direction. Furthermore, as shown in Figure 6, the height is formed in a dome shape of approximately 35 mm. The upper end surface of the lid 3 is integrally provided with a grip 12 that bulges upward and can be held by hand.

[0031] 3, a flange 13 formed to a predetermined width (for example, about 10 mm) is provided in a frame shape around the entire periphery of the lower end 3f of the lid 3. The lower surface 13f of this flange 13 is a flat horizontal surface, and engaging protrusions 4a, 4b... formed as downwardly protruding ridges are integrally provided on this lower surface 13f (lower end 3f).

[0032] In this case, four engaging protrusions 4a, 4b, 4c, and 4d are formed to a predetermined length along the horizontal sides 3a and 3b, which are the long sides, and the vertical sides 3c and 3d, which are the short sides. The positional relationship of these engaging protrusions 4a, 4b, 4c, and 4d is shown in Figure 5.

[0033] In this way, when forming the lid portion 3, the entire planar shape is formed into a rectangular shape, and four engaging protrusions 4a, 4b, 4c, 4d are formed to a predetermined length along the horizontal sides 3a, 3b and the vertical sides 3c, 3d.By combining this with the container main body portion 2, it can be easily and reliably offset and displaced, thereby improving usability (ease of use) and convenience.

[0034] The original function of the lid 3 is to be placed on the upper end 2u of the container body 2 and to close the opening 2o, as shown in FIG.

[0035] Next, the function (action) of the cooking container 1 according to this embodiment will be described with reference to FIGS.

[0036] The cooking container 1 according to this embodiment has a basic function of being easily switchable between the lid-closed mode Mc shown in FIG. 2 and the lid-open mode Mo shown in FIG.

[0037] First, in the lid-closed mode Mc, as shown in FIG. 2, the lid 3 is placed in the normal position on the opening 2o of the container body 2. This causes the lid 3 to close (fully close) the opening 2o. In this case, all four engaging protrusions 4a, 4b, 4c, and 4d on the lid 3 abut against the inner wall surface 2i of the container body 2, and the lower end 3f of the lid 3, i.e., the entire circumference of the flange 13, abuts against the upper end 2u of the container body 2. The four engaging protrusions 4a, 4b, 4c, and 4d restrict the lid 3 to a fixed position. Therefore, the position of the lid 3 will not shift unless the lid 3 is lifted upward.

[0038] As a result, in the lid closed mode Mc, the lid 3 is in the position shown by the dotted line in Figure 10, so the inside of the cooking container 1 is substantially sealed. This allows the internal air, such as steam, in the cooking container 1 to be conserved as shown by the dotted arrows Asi and does not leak out, preventing moisture from evaporating from the food and causing the food to dry out.

[0039] On the other hand, in the lid-open mode Mo, as shown in Fig. 1, the lid 3 is placed in a state where it is offset in the horizontal direction (one direction Fs) with respect to the opening 2o of the container body 2. This creates a partially opened portion 2os in the opening 2o. The displacement direction of this lid 3 is the offset direction.

[0040] That is, in the lid opening mode Mo, the gripping portion 12 is held with a hand or the like, the lid portion 3 is lifted, and then displaced horizontally (in one direction Fs), and the lid portion 3 is placed on the opening 2o of the container main body portion 2 at the displaced position.

[0041] 1, the lid 3 is placed in an offset state, so that the engaging protrusion 4b located on the offset side is located on the outer side of the container body 2, and the engaging protrusion 4a on the opposite side is displaced toward the inner side of the container body 2. In addition, the tip sides of the engaging protrusions 4c and 4d at other positions on the lid 3 are in contact with the inner wall surface 2i, and the lid 3 opens a part of the opening 2o of the container body 2.

[0042] 9, one engaging protrusion 4b of the lid 3 is located outside the side 2b of the container body 2 and is restricted by the outer wall surface 2m, and the end 4cs of the engaging protrusion 4c (same for the engaging protrusion 4d) of the lid 3 abuts against the inclined side 2cb of the container body 2, restricting its position. That is, the position is fixed without any positional deviation at the offset position.

[0043] As a result, in the lid open mode Mo, the lid part 3 is in the position shown by the solid line in FIG. The inside of the cooking container 1 is partially open, and the inside and outside of the container body 2 are in communication with each other through the partially open portion 2os, as shown by the solid arrow Aso, allowing some or all of the internal air to be exchanged with the external air. This alleviates the adverse effects of steam when reheating oily dishes such as tempura, fries, and deep-fried chicken, which can make the surface sticky and deteriorate the appearance and texture.

[0044] This lid-opening mode Mo can be selected between a first mode Moa in which the lid portion 3 is displaced vertically as shown in Fig. 7, and a second mode Mob in which the lid portion 3 is displaced horizontally as shown in Fig. 8. In the first mode Moa, a wider partially open portion 2os can be provided, and in the second mode Mob, a narrower partially open portion 2os can be provided.

[0045] Furthermore, because of this function, the open area of ​​the partially open portion 2os can be changed as desired by selecting the length and width of the engaging protrusions 4a, 4b, 4c, and 4d, as well as the length and angle of the inclined side portions 2ac, 2cb, 2bd, and 2da, and therefore it can be used in a variety of ways depending on the ingredients and dishes to be heated.

[0046] Therefore, the cooking container 1 according to this embodiment has, as its basic configuration, a lid 3 that abuts against the inner wall surface 2i of the container body 2 to restrict its position and has a plurality of engaging protrusions 4a, 4b… at its lower end 3f arranged at predetermined intervals, and a container body 2 in which, when the lid 3 is placed in an offset state in one direction Fs, the engaging protrusions 4b… located on the offset side are positioned on the outside, and the engaging protrusions 4c… located at other positions are restricted by the inner wall surface 2i. Therefore, the only components are the container body 2 and the lid 3, and no additional parts or special lids are required. This allows the container body 2 and the lid 3 to have simple shapes (configurations), which reduces costs in terms of materials and manufacturing, improves productivity, and allows for inexpensive provision. In addition, the product is easy to clean and easy to store.

[0047] Furthermore, the overall form (shape) is simple, and in particular the container body 2 does not have any unnecessary additional elements, so it can function not only as a cooking container but also satisfactorily design and function as tableware. Therefore, it can be offered as a product with high added value and marketability, as it fully ensures the functions of both a cooking container and tableware, and can enhance multifunctionality and versatility.

[0048] Although the preferred embodiment has been described in detail above, the present invention is not limited to such an embodiment, and the detailed configuration, shape, material, quantity, numerical values, etc. can be changed, added, or deleted as desired within the scope that does not deviate from the gist of the present invention.

[0049] For example, the planar shape of the cooking container 1 is preferably rectangular as shown in the example, but can basically be formed into any shape. Therefore, any shape, such as a square, polygon, circle, or ellipse, is not excluded. Furthermore, the engaging protrusions 4a... can be prevented from shifting relative to the container body 2 by selecting their length, but if necessary, the engaging protrusions 4a... may be made shorter to allow them to slide relative to the container body 2, so that the area of ​​the partially open portion 2os can be changed during use. Furthermore, while the lid 3 and container body 2 are formed integrally from synthetic resin or the like, this does not exclude the possibility of forming them from other materials, such as ceramics or metal. [Industrial Applicability]

[0050] The cooking container according to the present invention is a reheating container or other type of cooking container that includes a container body having an opening at the top end and a lid that is placed on the top end of the container body to close the opening. It can be used for. [Explanation of symbols]
