Description

  The present invention relates to a bamboo assembling container made of bamboo and a frozen food package using the same.

  Conventionally, as a container for packaging food such as lunch boxes and sushi, a folding box in which a thin strip-shaped plate material is folded to form a frame body and a bottom plate is joined to the frame body is the mainstream (see, for example, Patent Documents 1 and 2). . Further, from the viewpoint of environmental protection, the present inventor has developed various packaging containers using bamboo, which is one of natural materials that can be regenerated in a relatively short period of time even after logging (for example, , See Patent Document 3), and folding boxes made of such bamboo have been developed (see, for example, Patent Document 4).

  The bamboo folding box of Patent Document 4 is a folding box in which a single plate obtained by slicing bamboo is laminated and bonded so that its fiber directions are orthogonal to form a laminated plate, and this laminated plate is used as a material. More specifically, this folding box is provided with a concave groove that fits the bottom plate inside the lower part of the thick laminated board, a vertical concave groove is provided in front of the thin laminated board, and an adhesive is applied to the end face of the laminated board. Then, the bottom plate is fitted into the concave groove, the end of the laminated plate is applied to the bamboo nails, and the partition plate is inserted into the concave groove of the laminated plate.

  However, in the above conventional folding box, when a belt-like plate material is bent to form an annular frame, at least one place needs to be fixed using a stapler, an adhesive, or the like in order to form a ring. Further, in the bamboo folding box described in Patent Document 4, in order to join the ends of the four laminated plates to form an annular frame, a bamboo nail is driven into the end of the laminated plate as a fixing material and fixed. doing.

  As described above, in the conventional folding box, the folding box is always formed using a fixing material such as a stapler or an adhesive, so that the material cost increases accordingly. Further, since there is a process using these fixing materials, there is a problem that it takes extra time to assemble the folded box.

  Therefore, in the present invention, a bamboo assembling container that can be easily assembled in a short time without using any fixing material such as a stapler or an adhesive is provided. The purpose is to provide.

  The bamboo assembly-type container of the present invention is composed of four side wall plates and one bottom plate formed by a laminated plate obtained by laminating and bonding a single plate obtained by slicing bamboo so that the fiber directions thereof are orthogonal to each other. Each side wall plate includes a groove formed to fit the bottom plate, and a notch formed in a direction perpendicular to the groove to be inserted into the other side wall plate at both ends in the direction in which the groove is formed. It is a thing.

  According to the bamboo assembly-type container of the present invention, the frame body is formed by inserting the four side wall plates into each other through the respective notches. At this time, the bottom plate is held by each concave groove by inserting the four side wall plates so that the respective concave grooves are inside. Further, the side wall plate according to the present invention is obtained by laminating and bonding a single plate sliced from bamboo so that the fiber directions thereof are orthogonal to each other. Therefore, the side plate is extremely strong against bending, and the bottom plate is fitted in the groove in the frame. When inserting, one of the side wall plates can be bent and fitted.

  Here, it is desirable that the fiber direction of the outermost single plate of the side wall plate is the same as the direction in which the groove is formed. When the bottom plate is fitted into the concave groove of the frame, one of the side wall plates is curved in the direction of forming the concave groove, so that the largest bending force is applied to the outermost single plate of the side wall plate. If the fiber direction of the single plate is the same as the direction in which the concave grooves are formed, this outermost single plate can receive the greatest bending force.

  The distance between the end face of the side wall plate and the notch is preferably 5 mm or more. By setting it to 5 mm or more, when the bottom plate is fitted by bending one of the side wall plates of the frame body in the concave groove forming direction, the force acting on the notch forming portion can be sufficiently received by the bending force. If it is less than 5 mm, there is a possibility of cracking when the notch is formed in the side wall plate.

  The concave groove formed in the side wall plate can exert its bottom plate holding function as long as it is formed only in the portion where the bottom plate is fitted, but this concave groove is formed from one end surface of the side wall plate to the other end surface. It is desirable that Thereby, a ditch | groove can be uniformly formed from one end surface of a side wall board to the other end surface.

  The frozen food package in which the bamboo assembly-type container of the present invention is set includes four side wall plates formed by a laminated plate obtained by laminating and bonding a single plate obtained by slicing bamboo so that the fiber directions thereof are orthogonal to each other. It consists of one bottom plate and frozen food placed on the bottom plate, and the four side wall plates are a groove formed to fit the bottom plate, and another side wall plate at both ends of the groove forming direction. Each of which has a groove and a cutout formed in a vertical direction so that the four side wall plates are disposed on the surface opposite to the surface on which the frozen food is disposed. It is.

  In the frozen food package in which the bamboo assembly-type container of the present invention is set, the volume during transportation is only the bottom plate, the frozen food disposed on both sides of the bottom plate, and the four side wall plates. Further, when displaying frozen food, as described above, assembling the four side wall plates and the bottom plate allows the frozen food to be stored in the bamboo assembling container as a bamboo assembling container.

(1) It is composed of four side walls and one bottom plate formed by laminating and bonding a single plate obtained by slicing bamboo so that the fiber directions thereof are orthogonal to each other. Bamboo assemblable containers each having a groove formed for fitting and a notch formed in a direction perpendicular to the groove to be inserted into the other side wall plate at both ends in the groove forming direction. According to this, the frame is formed by inserting the four side wall plates into each other through the respective notches, and the bottom plate is held by the respective recessed grooves of the four side wall plates, so that the stapler, adhesive, etc. can be fixed. It can be easily assembled in a short time without using any material. Thereby, the bamboo assembly-type container of the present invention is composed only of four side wall plates and one bottom plate formed by a laminated plate obtained by laminating and bonding a single plate obtained by slicing bamboo so that the fiber directions thereof are orthogonal to each other. Since each of the side wall plate and the bottom plate is merely formed with a cutout and a concave groove, it is easy to keep the manufacturing cost low, and an inexpensive bamboo assembly-type container can be obtained. In addition, the bamboo prefabricated container of the present invention is obtained by laminating and bonding a single plate obtained by slicing bamboo so that the fiber directions thereof are orthogonal to each other. In addition to being able to bend and fit one of the side wall plates, the bamboo assemblable container is extremely strong against impacts during use. Furthermore, since it can be easily disassembled by the reverse procedure, it can be disassembled when not in use and the bamboo prefabricated container can be stored compactly. Moreover, by disassembling at the time of disposal, it becomes possible to discard without being bulky.

(2) Since the fiber direction of the outermost single plate of the side wall plate is the same as the direction in which the concave groove is formed, when the bottom plate is fitted into the concave groove of the frame body, the outermost single plate of the side wall plate It is possible to receive the largest bending force applied to the side wall plate and to prevent damage due to peeling of the outermost single plate of the side wall plate.

(3) When the distance between the end face of the side wall plate and the notch is 5 mm or more, when the bottom plate is fitted into the concave groove of the frame, the force acting on the notch forming portion can be sufficiently received. In addition, it is possible to prevent damage due to cracking of the notch forming portion.

(4) Since the concave groove is formed from one end surface of the side wall plate to the other end surface, the concave groove can be uniformly formed from one end surface of the side wall plate to the other end surface, The formation of the concave groove is facilitated, the manufacturing cost is reduced, and a cheaper bamboo assembly-type container can be obtained.

(5) By placing the four side wall plates on the surface opposite to the surface on which the frozen food is disposed on the bottom plate, the volume at the time of transportation is frozen on the bottom plate and on both surfaces of the bottom plate. Since only food and four side wall plates are used, the volume during transportation can be reduced by the gap between the container and the frozen food compared to the conventional transportation method in which the frozen food is previously stored in the container. it can. Thereby, the transportation cost at the time of transportation can be lowered. In addition, because the four side wall plates are arranged on one surface of the bottom plate, the container is not crushed even if it is vacuum packed, and the frozen food is kept longer by vacuum packing together with the frozen food. It becomes possible.

  FIG. 1 is a perspective view of a bamboo assembly-type container according to an embodiment of the present invention, and FIG. 2 is a plan view showing a state in which the bamboo assembly-type container of FIG. 1 is disassembled.

As shown in FIG. 3, the laminate made of bamboo is a natural material by laminating single plates 11, 12, 13, 14, 15 and 16 sliced from bamboo so that their fiber directions F are orthogonal to each other. It is pasted and glued with starch paste. In the example of FIG. 3, six single plates 11 to 16 are stacked. However, the number of stacked layers is not limited as long as it is two or more. In the case of three or more sheets, it is desirable that the fiber directions F of the outermost single plates 11 and 16 are the same direction.

  The single plates 11 to 16 are manufactured by the following steps. First, bamboo material cut to a length of about 40 cm is boiled in a steam kiln and softened, then peeled at a constant thickness, and cut into fixed lengths. The thin plate material taken out is sliced in parallel with the fiber direction F of the bamboo material. The thin plate material is taken out, dried, and pressed with a press in the thickness direction. Then, the thin plate material is cut into rectangles whose sides are parallel and perpendicular to the fiber direction F to form single plates 11 to 16.

  As a bamboo material, if the thickness is 10 mm or more, sliced thin plate materials can be taken out together. In particular, Chinese bamboo from China is the most suitable because it has a thickness of about 10 to 20 mm and can take out many thin plates. However, the bamboo skin is not used because its mechanical properties are significantly different from other parts.

  By cutting such a laminated plate, the side wall plates 1 to 4 and the bottom plate 5 as shown in FIG. 2 are formed. The side wall plates 1 to 4 and the bottom plate 5 are arranged such that the fiber directions F of the outermost single plates 11 and 16 are the respective longitudinal directions.

  Grooves 1a, 2a, 3a and 4a for fitting the bottom plate 5 are formed in the side wall plates 1 to 4, respectively. The concave grooves 1a, 2a, 3a and 4a are formed in the longitudinal direction of the side wall plates 1 to 4, that is, in the fiber direction F of the outermost single plates 11 and 16, respectively. Moreover, in this embodiment, the ditch | groove 1a, 2a, 3a, 4a is formed from the one end surface (upper and lower end surface of FIG. 2) of the side wall plates 1-4 to the other end surface.

  Further, notches 1b, 2b, 3b, and 4b are formed at both ends in the longitudinal direction of the side wall plates 1 to 4 at positions of about 6 mm from the respective end surfaces. The notches 1b and 2b of the side wall plates 1 and 2 are for inserting into the notches 3b and 4b of the side wall plates 3 and 4.

  In addition, when the notches 1b and 2b of the side wall plates 1 and 2 and the notches 3b and 4b of the side wall plates 3 and 4 are inserted, the concave grooves 1a, 2a, 3a and 4a become one ring, The notches 1b and 2b of the side wall plates 1 and 2 are formed at positions intersecting the concave grooves 1a and 2a, and the notches 3b and 4b of the side wall plates 3 and 4 are formed at positions not intersecting the concave grooves 3a and 4a. Yes. Further, the notches 1b, 2b, 3b, 4b are formed from the respective end surfaces (left end surface in FIG. 2) to the center of the side wall plates 1 to 4.

  A procedure for assembling a bamboo assembling container in the present embodiment with the side wall plates 1 to 4 and the bottom plate 5 having the above-described configuration will be described with reference to FIG.
