(How to use portable container 1)
Next, the usage method of the portable container 1 is demonstrated. In addition, this usage method is an example and you may use it by usage methods other than this.
First, an operator puts food in the container 30 shown in FIG. 1 and covers the container 30 with a lid 40. And an operator operates each operation member 35b, after locking each locking member 35a of the container 30 to the locking metal fitting 46 corresponding to it. Thereby, the lid 40 is pushed to the container 30 side by the fixing member 35 while compressing the packing 50. At this time, as shown in FIG. 3, the upper end of the standing portion 34 of the container 30 comes into contact with the bottom surface of the concave portion 42 of the lid 40, and the length L3 in the thickness direction of the lid 40 in the compressed packing 50 is This is the same as the length L2 in the same direction of the 30 standing portions 34. At this time, the base end portion of the tongue piece portion 50 b of the packing 50 comes into contact with the placement surface 33 of the container 30, and the base end portion of the tongue piece portion 50 b is compressed and deformed by the placement surface 33. Thereby, the water stop between the container 30 and the lid 40 is realized by the packing 50. Further, by forming the space S3 between the packing 50 and the lid 40, the packing 50 can be easily deformed, and the contact area between the mounting surface 33 and the tongue piece 50b of the packing 50 can be increased. , Water stoppage can be improved. Further, when the packing 50 is compressed, even if the base portion 50a of the packing 50 is deformed so as to bulge outward, the space 50 is present between the base portion 50a and the standing portion 34. The contact with the installation portion 34 is suppressed.

  Further, the operator removes each locking member 35a of the container 30 from the locking metal fitting 46 through the operation of the operation portion 35b. Thereafter, the operator removes the lid 40 from the container 30. At this time, the packing 50 returns to an uncompressed state.

(Method for stacking containers 30)
When storing the containers 30, a plurality of containers 30 can be stacked. Specifically, when stacking the first container that is the container 30 and the second container 30 that is a container 30 different from the first container 30, the lower surface of the stack portion 36 of the first container 30. Is brought into contact with the placement surface 33 of the second container 30. At this time, the internal space of the second container 30 communicates with the outside through the space between the stack portions 36 of the first container 30. Thereby, the moisture adhering in the 2nd container 30 can be escaped outside through this space at the time of container drying, and it can dry quickly.

(effect)
As mentioned above, according to one Embodiment described, there exist the following effects.

(1) The portable container 1 is positioned between a bottomed container 30 having an opening 31 at the top, a lid 40 covering the opening 31 of the container 30, and the opening 31 and the lid 40 of the container 30. A packing 50 and a fixing member 35 that fixes the lid 40 to the container 30 are provided. The container 30 is formed over the entire circumference of the opening 31, the mounting surface 33 with which one end of the packing 50 abuts, and the entire surface of the opening 31, and in a direction crossing the mounting surface 33 from the mounting surface 33. A standing portion 34 that extends and is smaller than the packing 50 that is not compressed in the same direction. The lid 40 is in a state of being fixed to the container 30 by the fixing member 35 and is in contact with the upper end of the standing portion 34 and the other end of the packing 50, and compresses the packing 50 with the mounting surface 33. 41 is provided.
According to this configuration, when the lid 40 is fixed to the container 30 by the fixing member 35, the lid 50 is compressed with an appropriate force by the lid collar portion 41 coming into contact with the upper end of the standing portion 34. Therefore, it is suppressed that the packing 50 is compressed with a force more than necessary. Therefore, deterioration of the packing 50 can be suppressed, and thereby the water stoppage of the packing 50 can be maintained. Further, when the lid 40 is fixed to the container 30 by the fixing member 35, the operation load of the operation portion 35b can be stabilized.

  (2) A space S <b> 2 is formed between the outer peripheral surface of the packing 50 and the standing portion 34 of the container 30. Therefore, when the container 40 is covered with the lid 40 and the packing 50 is compressed, even if the packing 50 is deformed so as to bulge outward, a space S2 exists between the packing 50 and the standing portion 34. Therefore, the packing 50 is prevented from coming into contact with the standing portion 34. Therefore, water can be reliably stopped by the packing 50. Further, the water can be stopped and the lid 40 can be easily attached to and detached from the container 30.

  (3) The container 30 includes an inner cylinder 32i and an outer cylinder 32o that is located outside the inner cylinder 32i and is connected to the inner cylinder 32i on the opening 31 side, and the inner cylinder 32i and the outer cylinder 32o A sealed space 32a is provided therebetween. According to this structure, the heat retention of the portable container 1 improves by making the container 30 into a two-layer structure.

  (4) The lid 40 includes a lid lower plate 43i located on the bottom plate 30a side of the container 30 and a lid top plate 43o located on the upper portion of the lid lower plate 43i when the lid 40 is fitted to the container 30. Prepare. A sealed space S1 is provided between the lid lower plate 43i and the lid top plate 43o. According to this structure, the heat retention of the portable container 1 improves by making the cover 40 into a two-layer structure.

  (5) The packing 50 is set to a color different from that of the container 30 and the lid 40. For example, since the container 30 and the lid 40 are made of stainless steel, they are silver and the packing 50 is colored blue as an example. Thereby, the operator can easily recognize whether or not the packing 50 is attached to the lid 40. In particular, when cleaning the lid 40, the packing 50 is removed from the lid 40. However, it is possible to prevent the user from forgetting to attach the packing 50 to the lid 40 after cleaning.

  (6) On the opening 31 side of the container 30, the standing portion 34 is formed by bending the inner cylinder 32 i and the outer cylinder 32 o. Since the mounting surface 33 is provided at the lower end of the standing portion 34, the mounting surface 33 is positioned adjacent to the joint portion between the inner cylinder 32 i and the outer cylinder 32 o. Since this joint location is a location with high deformation strength, the mounting surface 33 adjacent thereto is not deformed. Therefore, the mounting surface 33 has high shape accuracy, and the packing 50 is pressed by the mounting surface 33 with a stable force.

  (7) In the portable container 1, even if the mounting surface 33 is distorted, a part of the packing 50 is excessively compressed by the lid collar portion 41 coming into contact with the upper end of the standing portion 34. Can be suppressed. Therefore, the water stoppage of the packing 50 can be maintained.

(8) The lid collar portion 41 extends along the circumferential direction on the lower surface of the lid collar portion 41, and includes a recess 42 in which the standing portion 34 resides when the lid 40 is covered with the container 30. An annular base portion 50a attached to the inner peripheral surface 42a of the recess 42, and a tongue piece portion 50b that bends from the lower end of the base portion 50a toward the center of the lid 40 and whose tip portion abuts against the lower surface of the lid 40. A space is formed between the connecting portion of the base portion 50a and the tongue piece portion 50b and the lid 40.
According to this configuration, by forming the space S3, the packing 50 can be easily deformed, the contact area between the mounting surface 33 and the tongue piece portion 50b of the packing 50 can be increased, and the water stoppage is improved. be able to.
