Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a structure of a disposable paper packaging lunch box that can be used as a station lunch or a catered lunch for group customers.

[0002]

[Prior art]

 Conventionally, this type of lunch box for packaging used a foldable square paper box mainly composed of a body container and a lid, and contained various side dishes and rice together inside the body container and supplied them. . As disclosed in Utility Model Registration No. 3028706, the present applicant stores various prepared foods and rice in separate containers, stores the whole food in a large body container, and opens a window provided in a lid of the container. We are developing a packed lunch box that can be opened and closed so that only the rice cooker can be put in and out, and can be provided with a combination of hot rice for serving and selling.

[0003]

[Problems to be solved by the invention]

 Conventional paper lunch boxes are usually square, and circular or elliptical lunch boxes have not been adopted due to high manufacturing costs. However, a circular lunch box is necessary for supplying a wide variety of dishes as lunches. It would also be appreciated if hot rice and stewed food could be provided as a lunch box.

A first object of the present invention is to provide a structure in which a circular paper lunch box can be provided at low cost. The second purpose is to provide a window that can be opened and closed on a part of the lid as a packaged lunch box, from which it is possible to put in and out, for example, a separately cooked rice cooker or soup dish. The structure should be such that dust and dirt do not enter through windows.

[0005]

[Means for Solving the Problems] The lunch box for packaging according to the present invention comprises a circular outer box and an inner container which is housed in the outer box and directly stores food. For example, an outer box made of paper has a bottom plate 1b fitted from above into a short cylindrical bottom tube 1a having a lower end portion curled inward to form an inner flange 5, thereby forming a bottom body 1 and an upper end portion. A cover plate 2b is fitted from below into a short cylindrical cover tube 2a having an inner flange 6 formed by curling inward to form a cover 2, and the bottom 1 is attached to the lower end of a cylindrical body member 3. The lid 2 is fitted to the upper end. The body member 3 to be fitted to the bottom body 1 and the lid body 2 may be formed into a cylindrical shape with cardboard or the like, but a band member having a fixed width is bent into a cylindrical shape and engaged at a position having a predetermined diameter. You may make it do.

[0006]

[Embodiment of the invention]

 Hereinafter, an embodiment of a lunch box for packaging of the present invention will be described with reference to the accompanying drawings. FIG. 1 is an exploded perspective view of the entire packaging lunch box according to the present invention, FIG. 2 is an exploded perspective view showing the structure of a lid, and FIG. The basic configuration of the packing lunch box of the present invention is as follows. A short cylindrical bottom body 1 is fitted to a lower end of a body member 3 and a lid body 2 is fitted to an upper end to form an outer container, and food is stored therein. The inner container 4 is arranged.

As shown in FIG. 3, the bottom body 1 is composed of a bottom cylinder 1 a formed of a short cylinder using thick paper, and a disc-shaped bottom plate 1 b fitted into the bottom cylinder 1 a. The lower end of the short cylindrical bottom cylinder 1a is curled inward to form an inner flange 5, so that the bottom plate 1b fitted from above is supported. In order to stabilize the bottom body, it is preferable that the bottom plate 1b has a dimensional relationship in which the bottom plate 1b is forcibly fitted in a cramped state.

As shown in FIG. 2, the lid 2 is made up of a bottom cylinder 2a formed of a short cylinder using thick paper similarly to the bottom 1 and a disk-shaped lid plate 2b fitted into the lid cylinder 2a. Make up. The upper end of the short cylindrical lid tube 2a is curled inward to form an inner flange 6, so that the lid plate 2b fitted from below is supported. In addition, it is convenient that the bottom tube 1a and the cover tube 2a are common parts, and the bottom can be manufactured by fitting the bottom plate, and the cover 2 can be manufactured by fitting the cover plate. . Further, although both the bottom body 1 and the lid body 2 are shown as circular in the drawing, they may be elliptical or other modifications. In this case, this can be realized by manufacturing the bottom tube 1a and the cover tube 2a as cylindrical shapes, and fitting the deformed bottom plate 1b and the cover plate 2b such as an elliptical shape to deform the bottom tube 1a and the cover tube 2a. it can.

[0009] two of the cover plate to cover plate 2b in the illustrated embodiment, i.e. constituted by the rear surface lid plate 2b ₂ positioned with the rear surface cover plate 2b ₁ located above, rice instrument on the back cover plate 2b ₂ as well as bored window hole 7 sized to you to out etc., the surface cover plate 2b ₁ outwardly away certain dimensions than the window hole 7 of the back cover plate, at least the entire circumference of the of A notch 8 is provided except for a part to form a window cover 9 which can be freely opened and closed. Reference numeral 9a denotes a knob for opening and closing the window cover 9, which can be sealed by attaching a seal or the like thereto. Surface cover plate 2b ₁ and the back cover plate 2b ₂ may also be fitted to the lid tube 2a to align the window opening 7 and window cap 9 at separate state, but the surface cover plate 2b ₁ and the back cover plate 2b _It is preferred that ₂ be adhered at least partially so as not to cause displacement.

With the above-described lid structure, the rice cooker A can be taken out of the outer box by lifting and opening the window lid 9, and by closing the window lid 9, the window hole 7 is closed. It is. That is, a space for accommodating the rice cooker A is formed immediately below the window hole 7 in the inner container 4 accommodated in the outer box, and a space for accommodating the prepared food is arranged in other portions. In the example shown in FIG. 1, a window hole 7 is provided in the center of the cover plate, and a recess 10 into which the rice cooker A fits is formed in the center of the inner container 4 immediately below the cover, and the periphery is divided into a plurality. The recesses 11 and 11 are formed to accommodate side dishes.

In the embodiment shown in the drawings, the window cover 8 is formed to be slightly larger than the window hole 7, so that an overlap margin is formed. When the window cover 8 is closed, dust and dirt enter through the gap. Can be prevented. In the illustrated example, a thin dust-proof sheet 12 covers the upper part of the recess 11 for accommodating side dishes, except for the recess 10 for accommodating the rice cooker. Therefore, the side dishes can be protected as much as possible when opening and closing the window lid.

[0012] As a lunch box, it is conceivable to supply the whole box box including all the prepared dishes in a warm state, but it is not always necessary to warm up some foods such as salad fu pickles. If the whole prepared food is kept in a warm state for a long time, it tends to rot, which is not good for hygiene. For this reason, the storage space for warm food and cold food is divided into a single lunch box, and food that is preferably supplied in a warm condition is supplied separately in a warmed or heated condition. They are supplied at the time of sale or immediately before serving. As a food in a warm state, rice is a typical food as exemplified above, but soup, stew, curry and the like can be exemplified. In the illustrated example, the storage space for the rice cooker is shown as one place. However, window holes are provided in a plurality of places, and two or more rice cookers (curries) are provided in one recess for storing the rice cooker. A combination of rice and rice).

The outer case of the present invention is configured by fitting the bottom body 1 at the lower end of the body member 3 and the lid body 2 at the upper end. As the body member, a member formed in a cylindrical shape from the beginning may be used, or a belt-shaped member may be used by engaging a belt member at a predetermined position. Further, as the material of the body member, a simple cardboard such as cardboard may be used, but a cardboard cardboard having thickness and strength can be used. In that case, the corrugated paper corrugated paper fits tightly into the bottom tube and lid tube, and the box becomes stable.

Although the size of the outer box is determined by the diameter and the depth, in the present invention, the depth of the outer box (capacity of the outer box) can be easily changed by changing the body member. Further, the inner container 4 housed in the outer box does not require a large strength by itself, so that a tray container formed of a relatively thin synthetic resin material can be used. That is, in the present invention, the same bottom and lid are prepared by preparing tray containers having different depths as inner containers and combining body members (band members having different widths) corresponding to the depths of the tray containers. Thus, packing lunch boxes having different capacities can be easily provided.

[0015]

[Effect of the invention]

 According to the packing lunch box of the present invention described in claim 1, a paper lunch box of circular or oval shape can be economically provided. Then, only by changing the body member, it is possible to easily obtain ones having different capacities (depth) while using the bottom body and the lid body in common.

According to the invention of claim 2, a rice cooker or a juicer which is separately supplied by opening and closing a window cover of a cover plate is supplied to a customer in combination with other prepared foods immediately before serving or selling. It can provide a delicious and warm lunch. In this case, in the lunch box of the present invention, an overlap is formed between the window hole of the cover and the window cover, so that it is possible to improve the sanitary condition that dirt and dust hardly enter the lunch box.
