Description

  The present invention relates to a food container.

  Conventionally, containers made of various materials such as ceramics, metals, and resins are known as containers for storing food, and these containers are properly used depending on the type, use, purpose, etc. of the food to be stored. Yes.

In such a storage container, if there is only one type of food to be stored, one storage unit is sufficient. However, if two or more types of food are stored, the storage unit may have two or more storage units or partitions The necessity to divide one accommodating part into two or more arises.
As a container that can store two kinds of foods, for example, the one described in Patent Document 1 is known. In the container described in Patent Document 1, two storage portions are provided by forming raised partition walls on a container base made of a synthetic resin material.

JP 2005-170467 A

In the container described in Patent Document 1, the preservability of food is enhanced by providing a coating film formed of an ink having an antibacterial function on the surface of the container base that contacts the food. However, since the base material of this container is made of a synthetic resin material, it has a low microbial degradability and is not preferable in terms of environment.
The present invention has been completed based on the above circumstances, and an object of the present invention is to provide a container that has high microbial degradability and is environmentally preferable.

  In order to solve the above-mentioned problem, the present invention provides two main housing parts that are obtained by picking leaves of broad-leaved trees that have been subjected to salting treatment from a direction intersecting the main main veins, and the main veins that form the housing parts. After overlapping the petiole region including the end portion on the petiole side and the leaf tip region including the tip end portion of the leaf, the end portion arranged on the outside is sandwiched between the tip end portion of the leaf and the end portion on the petiole side A food container, comprising: a lid portion that is formed by bending two side edges toward the main vein side and closes the housing portion.

  The leaves of hardwood used as the material for the container of the present invention have the property that they can be decomposed by microorganisms. Therefore, according to the present invention, a container having high biodegradability can be provided.

The present invention may have the following configuration.
The leaves of the broad-leaved tree may be cypress leaves. The leaves of cypress are not only degradable by microorganisms, but also have antiseptic action. Therefore, according to the said structure, the storage container which is excellent in antiseptic | preservative action and has high microbial degradability can be provided. Furthermore, since the park leaves are resistant to fire, according to the above configuration, the contained food can be cooked by direct fire, and the use is wide.

  The back surface of the leaf may be arranged on the side in contact with the food. Since the back side surface of the broad-leaved tree has an uneven shape due to the protrusion of fibers, veins, and the like, such a configuration tends to allow the stored food to stay on the protrusion.

  As the leaves, a laminate in which two leaves are stacked in the middle face may be used. In the packaging process, when dried leaves are used, they are difficult to wrap and easy to tear. Therefore, with the above configuration, the back side of the leaf that is resistant to drying is arranged on the outside, so that drying can be prevented and it is easy to wrap and difficult to break.

  Natto may be stored in either one of the two storage units. With such a configuration, the odor unique to natto can be reduced.

  According to the present invention, a container having high microbial degradability can be provided.

In the present embodiment, as the leaf 1, a layered body 10 (corresponding to the leaf-leaf laminated body 10) obtained by stacking the two leaf leaves 1 </ b> A and 1 </ b> B is used (see FIG. 2). Of the two park leaves 1A, 1B shown in FIG. 2, the park leaves arranged on the upper side are designated as 1A, and the park leaves arranged on the lower side are designated as 1B.

  In the present embodiment, as the magnolia 1, the leaves of fallen cypress are washed, soaked in salt water for 10 to 20 days, subjected to a salting treatment, and then lightly washed out with salt water. The salt concentration during the salting treatment is preferably 30 to 40% with respect to the mass of the entire salt water. After performing these treatments, a number of holes are formed in the magnolia leaf 1 to enhance air permeability.

  Next, as shown in FIG. 2, the two leaves 1A and 1B are arranged with the front surface 3 on the inside (in the middle table), and the two leaves 1A and 1B on the petiole 2 side. The park leaf laminated body 10 (equivalent to the laminated body 10) is produced by overlapping so that the end portions 5A are arranged in the same direction. In the park leaf laminate 10, the surface 3 of the smooth leaf 1 is disposed on the inside, and the back surface 4 having an uneven shape is disposed on the outside. In the present embodiment, among the two park leaves 1A and 1B constituting the park leaf laminate 10, the park leaves 1B arranged on the lower side are larger than the park leaves 1A arranged on the upper side. Use a size. In FIG. 2 to FIG. 5, the shaded portion is the surface 3 of the magnolia leaf 1.

  Next, as shown in FIG. 3, the two storage portions 21 are formed by picking the lower side of the magnolia 1 from the direction intersecting the main vein 7. The two accommodating portions 21 have a substantially conical shape with the picked side as a common apex 21A, and the upper side in the drawing is open. Desired food 30 such as natto 30 and seasoning of natto 30 is accommodated in the formed two accommodating portions 21.
