[0015] Hereinafter, the container according to embodiments of the present invention will be described with reference to the accompanying drawings. like Figure 1 and Figure 2 As shown, the container 1 according to the first embodiment of the present invention is composed of a bottom 11 and a side portion 12 that are adhered to each other. The bottom 11 and the side portion 12 form a concave storage portion 1a with an opening at the top, and the storage portion 1a stores contents such as food.

[0016] The bottom 11 is a round base plate, which together with the side part 12 forms a box-shaped storage part 1a. The bottom 11 has at least a thickness capable of withstanding the weight of the contents such as food stored in the storage section 1a. In addition, the bottom 11 can be made of a single flat base plate, or it can be made by stacking multiple base plates.

[0017] The side portion 12 and the bottom portion 11 together form a box-shaped storage portion 1a. The side portion 12 is a strip-shaped body with an engaging protrusion 121 at one end serving as a first engaging portion and an engaging recess 122 at the other end serving as a second engaging portion. By engaging the engaging protrusion 121 and engaging the engaging recess 122 while flexing the whole, the side portion 12 is configured as an annular or cylindrical shape.

[0018] As described later, the side portion 12 is made of, for example, a wood-based material and is flexible. Therefore, it can be stored as a flat, strip-shaped component when the engaging protrusion 121 and engaging recess 122 are not engaged. On the other hand, when assembled for use, the entire assembly can be flexed to form a ring shape so that the engaging protrusion 121 and engaging recess 122 engage.

[0019] The side portion 12, which is configured as an annular shape, is formed in the circular opening at the upper and lower ends. At least one side of the opening on which the bottom 11 is installed has the same diameter as the bottom 11. Thus, the opening at one end of the side portion 12 is closed by the bottom 11 without gap.

[0020] In addition, the engagement shape of the engagement protrusion 121 and the engagement recess 122 is not particularly limited, and can be other shapes. In addition, the engaging parts of the engaging protrusion 121 and the engaging recess 122 can also be bonded with an adhesive, thereby preventing moisture or other substances from seeping or leaking out from the engaging parts.

[0021] like Figure 3 As shown in (a), the side portion 12 protrudes slightly downward from the bottom portion 11, and the protruding portion constitutes the leg portion 123. In this embodiment, a reinforcing sheet 1231 for reinforcing the leg portion 123 is further bonded from the inside. The result of having such legs 123 is that when the container 1 is placed on a platform such as a workbench, the legs 123 abut against the platform, while the bottom 11 does not abut against the platform.

[0022] In addition, such feet 123 are in Figure 4 It is preferable to use a lid 13 as shown to cover a container 1. Specifically, a circular fitting recess 1b is formed on the inner side of the foot 123. On the other hand, a protruding fitting protrusion 13a is provided above the lid 13, according to the shape of the circular fitting recess 1b. When multiple containers 1 are stacked with the lid 13 covering them, the fitting protrusion 13a engages with the fitting recess 1b. As a result, when containers 1 are stacked, they do not slip laterally, and the stacked containers are convenient to carry or store without distortion.

[0023] The container 1 can be made of various materials, but in this embodiment, the bottom 11 and the side 12 are both made of wood. Made of a wood-based material, the thin-walled side portion 12 is flexible and can be bent into a ring shape, allowing the engaging protrusion 121 to engage with the engaging recess 122. Furthermore, it creates a gentle and environmentally friendly atmosphere for the person holding the container 1.

[0024] On the other hand, when the material is made of wood, moisture can easily seep in from the cross-section along the fiber direction of the wood. That is, moisture can easily seep in from the periphery 11a of the bottom 11. Therefore, as Figure 3 As shown in (a), the cross-section represented by the periphery 11a of the bottom 11 is sealed with a water-insoluble or waterproof sealant S. Such a sealant S can be, for example, acrylic resin. In this way, by sealing the cross-section of the wood-based material, it is possible to effectively prevent moisture, oil, etc., from the food contents from seeping into the bottom 11.

[0025] It should be noted that, with Figure 3 Regardless of example (a), the section that appears in the width direction of the side portion 12 can also be sealed using the seal S.

[0026] Alternatively, the side portion 12 can be arranged parallel to the bottom 11 in the direction of the wood fibers. In this embodiment, the length direction of the side portion 12 is aligned with the direction of the wood fibers. This prevents moisture and other substances contained in the contents of food from seeping out along the fiber direction to the junction of the bottom 11 and the side portion 12, thereby ensuring durability.

[0027] like Figure 3 As shown in (a), the side portion 12 is bonded to the bottom 11 by an adhesive B between its inner peripheral surface 12a and the periphery 11a of the bottom 11, i.e., the thickness portion of the bottom 11. With the bottom 11 and the side portion 12 bonded together, the side portion 12 is positioned vertically at approximately a right angle relative to the bottom 11. The bonding portion is located at the opening on one side of the inner peripheral surface 12a of the side portion 12, thereby forming the storage portion 1a.

[0028] Furthermore, the periphery 11a of the bottom 11 is sealed by a sealant S, and adhesive B is bonded to the sealant S. However, since the sealant S, such as acrylic resin, also has adhesive properties, it is possible to seal the periphery 11a of the bottom 11 separately from the sealant S without using adhesive B, and to bond the bottom 11 to the side portion 12 using the sealant S. Also, as with the sealant S, it is preferable to use an adhesive B made of a hydrophobic or insoluble material.

[0029] In addition, Figure 3 In example (a), the periphery 11a of the bottom 11 is bonded to the portion of the inner peripheral surface 12a of the side portion 12 that is slightly inward from the end in the width direction, and a foot 123 is provided. However, if the foot 123 is not provided, as... Figure 3 As shown in (b), the periphery 11a of the bottom 11 can also be bonded to the end in the width direction of the inner peripheral surface 12a of the side portion 12.

[0030] When the side portion 12 is bonded to the bottom 11, for example, adhesive is applied beforehand to the periphery 11a of the bottom 11, which is sealed by the sealant S. Then, the side portion 12, which is not engaged with the engaging protrusion 121 and the engaging recess 122, is bonded to the inner peripheral surface 12a of the side portion 12 by wrapping it around the periphery 11a of the bottom 11, so that the engaging protrusion 121 engages with the engaging recess 122. Furthermore, when the side portion 12 is bonded by wrapping it around the periphery 11a of the bottom 11, a receiving portion 1a is formed at the position of the bottom 11 bonded to the inner peripheral surface 12a of the side portion 12, offset from one end of the opening.

[0031] There are no particular restrictions on the type of adhesive, but it is preferable to use an adhesive that will not affect the food or other contents.

[0032] According to the container 1 of this embodiment, even when food containing moisture or oil is stored in the storage part 1a, the moisture or oil of the food will not seep out or leak out of the container, resulting in excellent durability. In particular, although moisture or other contents of the food may easily seep out from the joint between the bottom 11 and the side part 12, the periphery 11a of the bottom 11 and the inner peripheral surface 12a of the side part 12 are bonded together by an adhesive. As a result, moisture is retained and does not easily seep out, thus exhibiting high durability.

[0033] Additionally, a thin-walled waterproof membrane or sheet can be laminated onto the surfaces of the bottom 11 and side portions 12, especially the surfaces in contact with the contents. This prevents moisture and oil from seeping through the surfaces of the bottom 11 and side portions 12. [Example 2]

[0034] Figure 5 and Figure 6 This refers to container 2 according to the second embodiment of the present invention. Container 2, like container 1, is composed of a bottom 21 and a side portion 22, which are glued together to form a storage portion 2a for holding the contents. Furthermore, container 2 also has the same structure as container 1, such as the leg portion 223 reinforced by the reinforcing plate 2231, the side portion 22 engaging with this point by the engaging protrusion 221 and engaging recess 222, and the point made of a wooden material. In this embodiment, the side portion 22 is provided with a tapered shape that expands in diameter in the direction opposite to the bottom 21. That is, among the side portions 22 that are open at both ends, the diameter of the opening on the opposite side is larger than the diameter of the opening on the side where the bottom 11 is mounted.

[0035] Therefore, multiple containers 2 can be stacked by storing other containers 2 in the storage section 2a of one container 2. As a result, even when the container 2 is assembled by bonding the bottom 21 to the side 22, the volume of the container 2 will not increase when it is stored in storage or transported.

[0036] In addition, such as Figure 7 As shown, in container 2, the periphery 21a of the bottom 21 is also sealed by the sealant S, and the side portion 22 has its inner peripheral surface 22a adhered to the periphery 21a of the bottom 21. Here, the side portion 22 of the container 2 has a conical shape, resulting in a roughly V-shaped groove G formed between the side portion 22, which has a certain thickness, and the bottom 21. In this embodiment, at least the groove G is coated with adhesive B to bond the bottom 21 and the side portion 22, and the groove G is filled to prevent the presence of depressions at the joint between the bottom 21 and the side portion 22 that could easily accumulate moisture, oil, etc. Thus, even in the container 2 with the conical side portion 22, it is possible to prevent moisture or other substances from seeping or leaking out from the joint between the bottom 21 and the side portion 22, as revealed by the cross-section of the bottom 21.

[0037] Furthermore, regarding the container 2 of this embodiment 2, a lid identical to the lid 13 of embodiment 1 described above can be provided according to the shape of the container 2. Additionally, the surfaces of the bottom 21 and the side portions 22 can be laminated with a waterproof sheet or film. [Example 3]

[0038] In the above-described embodiment, the bottoms 11 and 21 of containers 1 and 2 are circular, and containers 1 and 2 themselves are generally cylindrical with one end closed. However, in other embodiments, the bottoms may be rectangular, elliptical, polygonal, or other shapes. As an example Figure 8 This indicates a container 3 having a bottom 31 consisting of a rectangle. The container 3 consists of a rectangular bottom 31 and rectangular frame-shaped side sections 32.

[0039] The side portion 32 is a strip-shaped body with an engaging protrusion 321 forming a first engaging portion at one end and an engaging recess 322 forming a second engaging portion at the other end. By bending it at an appropriate location to match the shape of the bottom 31, and engaging the engaging protrusion 321 and the engaging recess 322, the side portion 32 is configured as a rectangular frame.

[0040] The side portion 32 is bonded to the bottom 31 by an adhesive between it and the periphery 31a of the bottom 31, i.e., the thickness portion of the bottom 31. The bonded portion is located at the one-sided opening in the inner peripheral surface 32a of the side portion 32, thereby forming a storage portion capable of holding contents.

[0041] Furthermore, the container 3 can also be made of the same wooden material as the container 1. Additionally, the engaging portions of the engaging protrusion 321 and engaging recess 322 can be bonded together using adhesive. Alternatively, a conical shape can be added for stacking, or a lid similar in shape to the lid 13 can be used. Furthermore, the surfaces of the bottom 31 and the side portions 32 can be laminated with a waterproof sheet or film. (Label Explanation)
