  An object of the present invention is a packaging container configured by combining two containers, and provides a packaging container that is convenient for handling while devising a connection structure of each container so that both containers can be used for cooking together. That is.

  The packaging container of the present invention includes first and second containers. Each container is provided with a flange portion at the periphery of the opening, and is detachably connected using a connecting member in a state where the flange portions are attached to each other.

  Here, the “flange portion” means a structure protruding outward from the periphery of the opening. This includes not only a generally called flat flange portion (ie, a flange portion) but also a configuration in which the peripheral edge of the opening of the container is curled and protruded.

  In the packaging container of the present invention having the above-described configuration, two types of food can be cooked using two separate and independent containers (for example, noodles and sauce in instant spaghetti). Therefore, it is very suitable for providing various instant foods.

In addition, the connecting member used to connect the two containers can be used as a heat insulating member particularly when the connecting member is configured as a belt-like body or a box-like body, which is convenient for consumers.
That is, in the case of an instant food that is cooked using hot water, even when the consumer holds the container by hand during cooking or eating, the connecting member is interposed so that the heat is not felt much.

  Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 shows a packaging container according to a first embodiment of the present invention.

<< First Embodiment (FIG. 1) >>
The packaging container shown in FIGS. 1A and 1B is composed of a first container 100 positioned on the upper side, a second container 200 positioned on the lower side, and a connecting member 300 that connects the two. ing.
The first container 100 has a curled flange portion 101 on the periphery of the opening. Similarly, the 2nd container 200 has the curled flange part 201 in the opening periphery.
The first container 100 and the second container 200 are stacked with the flange portions 101 and 201 attached to each other, and are connected to each other using a connecting member 300 in a separable manner.

The 1st container 100 is provided with the taper-shaped surrounding wall 102, and the connection member 300 is provided with the taper-shaped surrounding wall 301 fitted on this.
The connecting member 300 is formed in a tapered band shape as a whole, and integrally includes a protruding region 304 that protrudes from the larger diameter side. A slit 305 extending in the circumferential direction is formed in the protruding region 304, and a protruding piece 306 (engagement portion) is formed from one side of the slit 305 toward the small diameter portion of the tapered peripheral wall 301. It protrudes.

  As shown in FIG. 1A, the flange portions 101 and 201 in an associated state are positioned in the slit 305 of the connecting member 300, and the projecting piece 306 (engagement portion) is a curled flange from the lower side. The first container 100 and the second container 200 are held in a connected state by engaging with the part 201.

  In the illustrated example, the protruding piece 306 is engaged so as to bite into the root of the curled flange portion 201. However, if the flange portion is configured to protrude further outward, the projecting piece 306 can be omitted and a simple slit can be used as the engaging portion.

  In the example shown in the figure, the connecting member 300 is provided with two protruding regions 304, and therefore the slits 305 are also present at two locations. However, the slits do not necessarily have to be attached to the projecting region, and the number of slits can be three or more.

≪When applied to instant spaghetti≫
For example, when the packaging container of FIG. 1 is applied to an instant spaghetti, the following usage mode can be considered.
The peripheral opening of the first container 100 is sealed with a sheet-like lid material (not shown) as seen in a normal instant ramen with cup. That is, dry noodles are put into the 1st container 100, hot water is poured into this, and it seals with the said cover material. After a predetermined time has elapsed, the lid is removed and noodles (pasta) are completed.
On the other hand, the second container 200 is not provided with such a lid material and is always open. Put the retort pack filled with the sauce into the second container 200 and pour hot water. After a predetermined time has elapsed, the hot water is discarded, the retort pack is opened, and the sauce is taken out into the second container 200.
Thus, the state which cooked noodles (pasta) and the sauce separately and was able to eat is shown schematically in FIG.1 (b).
The dried noodles, the retort pack in which the sauce is sealed, and other ingredients are accommodated in the first container 100 or the second container 200, for example, individually in a bag. And in the state which connected both the containers 100 and 200 with the connection member 300, it sells as an instant food. At this time, if necessary, the entire container is shrunk with a transparent film 130 as shown in FIG.

  Of course, it is possible to adopt various usage modes other than the instant spaghetti. Which of the first container and the second container is provided with a sheet-like lid is appropriately selected depending on what kind of instant food the packaging container is applied to, or how the cooking method is set. be able to.

  Since the whole connecting member 300 has a strip shape, as shown in FIG. 1 (b), it can be disposed around the container and used as a heat insulating material during eating or cooking. That is, even when the consumer holds the container directly by hand, the connection member 300 is interposed, so that the heat can be hardly felt.

  Next, another embodiment of the present invention will be described with reference to FIG. Since the basic structure and idea are the same as those of the first embodiment, different parts will be described with emphasis.
