The above-mentioned lower part 20 of the container body (excluding the elastic member 35 described later), the upper part 40 of the container body, and the opening / closing lid 60 are all obtained by injection molding using polypropylene (PP), but in addition to this, polyethylene (PE). ), Acrylonitrile (ABS), a resin in which polypropylene (PP) and polyethylene (PE) are blended, or the like may be used for molding. Further, when the lower part 20 of the container body (excluding the elastic member 35 described later), the upper part 40 of the container body and the opening / closing lid 60 are molded using polyethylene, the polyethylene may be polyethylene derived from biomass. Further, silicon rubber may be used as the plate rubber 12. The lower part 20 of the container body and the upper part 40 of the container body can be integrally molded by injection molding.

Next, the storage container 10 according to the present embodiment will be described in detail with reference to FIGS. 5 and 6. Here, FIG. 5 is an enlarged view of the V portion of FIG.

As shown in FIG. 5, a first fitting portion 30 including a recess 33 composed of an inner peripheral wall 31 and an outer peripheral wall 32 is formed on the lower peripheral wall portion 22 of the container main body lower portion 20, and the upper portion of the container main body upper 40 is formed. A second fitting portion 50 to be inserted into the recess 33 is formed in the peripheral wall portion 41. In the present embodiment, the first fitting portion 30 is formed at the upper end portion of the lower peripheral wall portion 22. On the other hand, the second fitting portion 50 is formed at the lower end portion of the upper peripheral wall portion 41. The first fitting portion 30 is preferably formed in a region of 70% or more of the entire circumference of the lower peripheral wall portion 22, and more preferably 90% or more. Similarly, the second fitting portion 50 is preferably formed in a region of 70% or more, and more preferably 90% or more of the entire circumference of the upper peripheral wall portion 41. In the illustrated example, the first fitting portion 30 is formed over the entire circumference of the lower peripheral wall portion 22 (see FIG. 3). Similarly, the second fitting portion 50 is formed over the entire circumference of the upper peripheral wall portion 41.

Next, the first fitting portion 30 will be described. As shown in FIGS. 5 and 6, the first fitting portion 30 is provided in a main body (first fitting portion main body) 34 in which the recess 33 is formed and an elastic member (1st fitting portion main body) 34 provided in the recess 33 and containing an elastomer material. The first fitting portion contact member) 35 and the like are included. Of these, the main body 34 is molded by injection molding using the above-mentioned resin such as polypropylene.

The main body 34 includes a base portion 36 and the above-mentioned inner peripheral wall 31 and outer peripheral wall 32 extending upward from the base portion 36, respectively. Of these, the base portion 36 is thicker than the other portions of the lower peripheral wall portion 22. As a result, the strength of the first fitting portion 30 can be increased, and when the first fitting portion 30 and the second fitting portion 50 are fitted to each other, the first fitting portion 30 is deformed. It is possible to prevent it from being stored. Therefore, it is possible to prevent the formation of a gap for communicating the inside and the outside of the storage container 10 between the first fitting portion 30 and the second fitting portion 50. As a result, the sealing property of the storage container 10 can be improved. The thickness t1 of the base portion 36 (see FIG. 6) may be about 2.4 mm or more and 5.0 mm or less. Further, the height (vertical distance) h1 (see FIG. 6) of the base portion 36 may be about 1.0 mm or more and 3.0 mm or less.

The upper surface 31a of the inner peripheral wall 31 of the main body 34 and the upper surface 32a of the outer peripheral wall 32 are configured to be positioned on the same plane with each other in the vertical direction. The thickness t2 of the inner peripheral wall 31 and the thickness t3 of the outer peripheral wall 32 (see FIG. 6) may be about 0.7 mm or more and 1.5 mm or less, respectively.

As described above, the recess 33 is formed by the inner peripheral wall 31 and the outer peripheral wall 32. The recess 33 includes an inner surface 33a on the inner peripheral wall 31 side, an outer surface 33b on the outer peripheral wall 32 side, and a bottom surface 33c located between the inner surface 33a and the outer surface 33b. The depth (vertical distance) d (see FIG. 6) of such a recess 33 may be about 1.0 mm or more and 10 mm or less. Further, the width of the recess 33 (distance in the thickness direction of the lower peripheral wall portion 22) w1 (see FIG. 6) may be about 1.0 mm or more and 2.0 mm or less. In the present specification, the “bottom surface of the recess” means a surface located between the inner surface 33a and the outer surface 33b in the recess 33. That is, as will be described later, even when the recess 33 is recessed upward, the surface located between the inner surface 33a and the outer surface 33b in the recess 33 is referred to as a bottom surface.

Further, as described above, the elastic member 35 is provided in the recess 33. Since the elastic member 35 is provided in the recess 33, the surface area of the elastic member 35 exposed to the outside air when the upper portion 40 of the container body is closed can be reduced. As a result, it is possible to prevent the elastic member 35 from deteriorating due to exposure to the outside air. In the present embodiment, the elastic member 35 described above is provided on the bottom surface 33c. The elastic member 35 is preferably provided in a region of 70% or more of the entire circumference of the recess 33, and more preferably 90% or more of the entire circumference of the recess 33. In the illustrated example, the elastic member 35 is provided over the entire circumference of the recess 33.

The elastic member 35 provided on the bottom surface 33c of the recess 33 has a convex shape. In this case, the elastic member 35 projects upward. As a result, when the second fitting portion 50 comes into contact with the elastic member 35 from above, the second fitting portion 50 can easily crush the elastic member 35. Then, the second fitting portion 50 crushes the elastic member 35, so that a gap is formed between the second fitting portion 50 and the elastic member 35 to communicate the inside and the outside of the storage container 10. Can be suppressed. Therefore, the sealing property of the storage container 10 can be improved. The height (protrusion amount) h2 (see FIG. 6) of the elastic member 35 may be about 0.3 mm or more and 1.0 mm or less.

As such an elastic member 35, for example, an olefin-based or silicon-based thermoplastic elastomer, or an elastically deformable soft member such as silicon rubber can be used. Further, the elastic member 35 may be molded together with the main body 34 by, for example, injection molding (so-called two-color molding), or may be pushed into the recess 33 of the main body 34 after the main body 34 is molded. At this time, the elastic member 35 may be attached to the recess 33 of the main body 34 by, for example, an adhesive or the like.

Next, the second fitting portion 50 will be described with reference to FIG. The second fitting portion 50 is configured to come into contact with the elastic member 35 when the upper portion 40 of the container body is closed. In this case, the second fitting portion 50 preferably abuts on the elastic member 35 in a region of 70% or more of the entire circumference of the lower peripheral wall portion 22, and abuts on the elastic member 35 in a region of 90% or more. Is more preferable. The second fitting portion 50 comes into contact with the elastic member 35 in a region of 70% or more of the entire circumference of the lower peripheral wall portion 22, so that the sealing property of the storage container 10 can be improved. In the illustrated example, the second fitting portion 50 is in contact with the elastic member 35 over the entire circumference of the lower peripheral wall portion 22. In this way, the second fitting portion 50 is in contact with the elastic member 35 over the entire circumference of the lower peripheral wall portion 22, so that the sealing property of the storage container 10 can be further improved.

As shown in FIG. 5, the second fitting portion 50 includes a main body (second fitting portion main body) 51 formed by injection molding using the resin or the like such as polypropylene described above. The main body 51 includes a base 52 and a protrusion 53 extending downward from the base 52. Of these, the base portion 52 is thicker than the other portions of the upper peripheral wall portion 41. As a result, the strength of the second fitting portion 50 can be increased, and when the first fitting portion 30 and the second fitting portion 50 are fitted to each other, the second fitting portion 50 is deformed. It is possible to prevent it from being stored. Therefore, it is possible to prevent the formation of a gap for communicating the inside and the outside of the storage container 10 between the first fitting portion 30 and the second fitting portion 50. As a result, the sealing property of the storage container 10 can be improved. The thickness t4 of the base portion 52 may be about 2.4 mm or more and 5.0 mm or less. Further, the height (vertical distance) h3 of the base portion 52 may be about 1.0 mm or more and 2.0 mm or less.

Further, the lower surface 52a of the base portion 52 is in contact with the upper surface 31a of the inner peripheral wall 31 and the upper surface 32a of the outer peripheral wall 32 when the upper portion 40 of the container body is closed. Thereby, the sealing property of the storage container 10 can be further improved. A gap may be formed between the upper surface 31a of the inner peripheral wall 31 and the upper surface 32a of the outer peripheral wall 32 and the lower surface 52a of the base 52 of the second fitting portion 50.

The protruding portion 53 of the second fitting portion 50 is a portion inserted into the recess 33 of the first fitting portion 30. In the present embodiment, the lower surface 53a of the protrusion 53 is in contact with the elastic member 35 provided in the recess 33. On the other hand, a gap is provided between the inner peripheral surface 53b of the protruding portion 53 and the inner surface 33a of the recess 33. Similarly, a gap is provided between the outer peripheral surface 53c of the protrusion 53 and the outer surface 33b of the recess 33. This makes it easier to insert the protrusion 53 into the recess 33. The thickness t5 of the protruding portion 53 may be about 0.7 mm or more and 1.5 mm or less. Further, the height (vertical distance) h4 of the protruding portion 53 may be about 0.7 mm or more and 9.0 mm or less.

The outer peripheral surface of the second fitting portion 50 (the outermost surface of the surfaces of the second fitting portion 50 in the thickness direction) 50a is the outer peripheral surface (the first) of the first fitting portion 30 described above. Of the surfaces of 1 fitting portion 30, it is preferable that the surfaces are flush with 30a (the outermost surface in the thickness direction) 30a. As a result, it is possible to prevent the user from feeling uncomfortable when carrying the storage container 10. Further, since the outer peripheral surface 50a of the second fitting portion 50 is flush with the outer peripheral surface 30a of the first fitting portion 30, the first fitting portion 30 or the second fitting portion of the storage container 10 is flush with the outer peripheral surface 30a. It is possible to prevent the upper portion 40 of the container body from opening when an unintended force acts on the 50.

Next, the operation of the present embodiment having such a configuration will be described.

First, the upper part 40 of the container body of the storage container 10 is opened, and the sheet-shaped article 1 is placed on the lower part 20 of the container body. The sheet-shaped article 1 may be, for example, a wet tissue impregnated with alcohol.

Next, a part of the article 1 is pulled upward from the outlet 42 of the upper part 40 of the container body. Then, the opening / closing lid 60 is closed.

Next, the upper part 40 of the container body is closed. At this time, as shown in FIG. 7A, the protruding portion 53 of the second fitting portion 50 of the upper portion 40 of the container body is inserted into the recess 33 of the first fitting portion 30 of the lower portion 20 of the container body from above. To. Then, the protruding portion 53 of the second fitting portion 50 inserted into the recess 33 comes into contact with the elastic member 35 provided in the recess 33 (see the virtual line (dashed line)).

Next, as shown in FIG. 7B, the second fitting portion 50 is fitted to the first fitting portion 30. At this time, the second fitting portion 50 crushes the elastic member 35. Here, the elastic member 35 has a convex shape (see FIG. 7A). Therefore, when the second fitting portion 50 comes into contact with the elastic member 35 from above, the elastic member 35 is easily crushed by the second fitting portion 50. By crushing the elastic member 35 by the second fitting portion 50 in this way, a gap is formed between the second fitting portion 50 and the elastic member 35 to communicate the inside and the outside of the storage container 10. It can be effectively suppressed. Therefore, the sealing property of the storage container 10 can be improved. Then, the lower surface 52a of the base portion 52 of the second fitting portion 50 comes into contact with the upper surface 31a of the inner peripheral wall 31 of the first fitting portion 30 and the upper surface 32a of the outer peripheral wall 32.
