DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, an embodiment of the sealed container of the present invention will be described with reference to the drawings. The sealed container of the present invention not only improves the sealing performance of the inside of the container, but also reduces the amount of force required to attach and detach the lid to and from the container body compared to the conventional method. [First embodiment]

[0014] As shown in Figures 1 to 3 and 11, the sealed container 11 has a box-shaped container body 14 having an opening 12 at the top and an opening end face 13 surrounding it, a lid 15 covering the opening 12 and the opening end face 13, and an annular gasket 16 that seals the gap between the inner surface 14A of the container body 14 and the lid 15 near the opening end face 13.

[0015] As shown in Figs. 1 to 3 and 11, the box-shaped container body 14 has an inner surface 14A. More specifically, the container body 14 has a bottom wall 17, a side wall 18 rising from the bottom wall 17, an opening end surface 13 located at an end of the side wall 18 opposite to the end on the bottom wall 17 side, and a total of four ribs 21 provided so as to protrude from the opening end surface 13. The container body 14 is integrally molded, for example, from a translucent resin. The ribs 21 are an example of a first step protruding from the opening end surface 13.

[0016] The side wall portion 18 has a total of four flat side walls 18A and a total of four corners 18B each having an arc-shaped cross section and connecting the side walls 18A. As shown in FIG. 11, the four ribs 21 are provided at positions corresponding to the four side walls 18A. The thickness dimension of the rib 21 is smaller than the thickness dimension of the side wall 18A. The rib 21 is provided at the innermost position of the opening end surface 13 so as to be aligned with the inner surface 14A (the inner surface of the side wall portion 18) of the container body 14. The rib 21 has gentle slope portions 21A at both left and right ends so that it is not a problem if the user touches it with his or her hands.

[0017] 4, the lid body 15 has an outer lid 22, an inner lid 23 located inside the container body 14, a lever 24 that suspends the inner lid 23 from the outer lid 22 and raises and lowers the inner lid 23, and a spacer member 25 interposed between a pair of protruding pieces 55 of an arm portion 53 (described later) of the inner lid 23. The outer lid 22 includes a first member 31 exposed to the outside, and a second member 32 provided on the inner surface side of the first member 31 and fitted with the first member 31. Each of the first member 31, the second member 32, the inner lid 23, the lever 24, and the spacer member 25 is molded from resin.

[0018] 5, 12, and 13, the first member 31 constitutes the outer edge of the lid 15, and also constitutes a portion that is exposed to the outside even when attached to the container body 14. The first member 31 is formed in a generally flat plate shape overall, although it includes some irregularities. The first member 31 has a plate-shaped first member body 33, a frame portion 34 protruding from the outer edge of the back surface of the first member body 33, an abutment surface 35 provided at a portion of the frame portion 34 facing the container body 14, a first step portion 36 extending in a strip shape from the outer periphery of the first member body 33 toward the center and recessed in a step shape from the surroundings, a second step portion 37 provided in the center of the first member body 33 so as to be continuous with the first step portion 36 and recessed in a step shape deeper than the first step portion 36, a square first through hole 38 provided at the bottom of the second step portion 37, and a plurality of claw portions (not shown) provided in the first member body 33 and engaging with the fixing hole 45 of the second member 32. An arm portion 53 of the inner lid 23, which will be described later, is passed through the first through hole 38.

[0019] The abutment surface 35 can abut against the opening end surface 13 of the container body 14. As shown in Figs. 14 and 15, the abutment surface 35 has a recess 35A capable of accommodating the rib 21 provided on the container body 14, and an outer peripheral surface 35B defining the periphery of the recess 35A. The recess 35A is formed recessed from other parts constituting the abutment surface 35. The outer peripheral surface 35B is configured to be able to engage with the outer surface of the rib 21. The outer peripheral surface 35B is an example of a second step portion that protrudes from the abutment surface 35 and is able to engage with the first step portion (rib 21). By engaging with the outer surface of the rib 21, the outer peripheral surface 35B can correctly hold the lid body 15 in the center of the container body 14 and ensure sealing. In addition, when the container body 14 tries to expand outward due to the pressing force of the packing 16, the outer peripheral surface 35B can engage with the outer surface of the rib 21 to prevent deformation of the container body 14. These improve the sealing performance of the sealed container 11 more than ever before. Note that the arrangement in this embodiment is merely an example, and for example, a rib 21 (second step) may be provided on the abutment surface 35 of the lid 15, and a recess 35A and an outer peripheral surface 35B (first step) may be provided on the opening end surface 13 of the container body 14. This allows the outer peripheral surface 35B to engage with the outer surface of the rib 21, providing the same effect as this embodiment.

[0020] 6, 12, and 13, the second member 32 has a flat second member body 41, an annular spacer wall portion 42 protruding from near the outer edge of the surface of the second member body 41 toward the first member 31, a square second through hole 43 provided in the center of the second member body 41, a pair of circular third through holes 44 provided on both sides of the second member body 41 sandwiching the second through hole 43, and a plurality of fixing holes 45 provided in the spacer wall portion 42 with which a plurality of claw portions of the first member 31 are engaged. The second member 32 is fixed to the first member 31 so as to be integrated with the first member 31 by fitting the plurality of claw portions of the first member 31 into the plurality of fixing holes 45.

[0021] An arm portion 53 of the inner lid, which will be described later, is passed through the second through hole 43. The pair of third through holes 44 form a pair of recessed portions for guiding a pair of guide posts 54, which will be described later, of the inner lid 23. Each of the pair of third through holes 44 forms a circular recessed portion complementary to the cylindrical guide post 54, which will be described later. Then, each of the pair of third through holes 44 is inserted and guided by each of the pair of guide posts 54, which will be described later, of the inner lid 23.

[0022] With the second member 32 engaged with the first member 31, a first mounting portion 46 is formed by an annular recess between the first member 31 and the second member 32. The first mounting portion 46 is provided on the inside of the contact surface 35. As shown in Figures 14, 15, 16, and 17, a first base portion 74 of the packing 16, which will be described later, is attached to the first mounting portion 46.

[0023] As shown in Fig. 3 and Fig. 12, the inner lid 23 is positioned inside the container body 14 together with the packing 16. As shown in Fig. 7, the inner lid 23 has an inner lid body 51 having a flat plate shape, a second mounting portion 52 formed in an annular shape recessed inward from the outer edge of the inner lid body 51, an arm portion 53 protruding from the inner lid body 51 forming the second mounting portion 52 toward the outer lid 22, and a pair of guide posts 54 provided on both sides of the arm portion 53 and protruding from the inner lid body 51 toward the outer lid 22. A second base portion 75 of the packing 16 described later is attached to the second mounting portion 52.

[0024] The arm 53 penetrates the outer lid 22 and protrudes to the outside of the container body 14. The arm 53 has a pair of projections 55 facing each other, a pair of rails 56 provided on the inner surfaces of the pair of projections 55, and a pair of shafts 57 provided at the tips of the outer surfaces of the pair of projections 55. The tips of the pair of projections 55 are formed, for example, in an arc shape. The spacer member 25 can be inserted between the pair of projections 55. The shafts 57 form a part of the engagement shaft for engaging the lever 24 and the arm 53. Each of the pair of guide posts 54 is formed in a cylindrical shape. The shape of the guide post 54 is not limited to a cylindrical shape, and may be various shapes such as a cylindrical shape, a rectangular prism shape, or a flat plate shape.

[0025] The lever 24 is provided on the outside of the container body 14. As shown in Fig. 13, the lever 24 abuts against the outer lid 22 and can suspend the inner lid 23 in that state. The lever 24 is connected to the inner lid 23 via an arm portion 53. The lever 24 can raise and lower the inner lid 23 by rotating while abutting against the outer lid 22.

[0026] As shown in FIG. 8, the lever 24 has a lever body 61 in the shape of a long and narrow plate, a pair of overhanging parts 62 provided at the base of the lever body 61, a finger hook part 63 provided at the tip of the lever body 61, a pair of circular bearing holes 64 provided in the pair of overhanging parts 62, and a first cam surface 65 and a second cam surface 66 provided in the pair of overhanging parts 62. The pair of bearing holes 64 constitute a part of an engagement shaft part for engaging the lever 24 with the arm part 53. The pair of shaft parts 57 of the inner lid 23 are inserted into the pair of bearing holes 64, so that the inner lid 23 is suspended from the lever 24. This structure also allows the lever 24 to rotate with respect to the outer lid 22 and the inner lid 23. That is, the lever 24 is rotatable about a pair of shafts 57 between a first position P1 in which the lever 24 is laid horizontally along the outer surface (first member 31) of the outer lid 22, and a second position P2 in which the lever 24 is upright relative to the outer lid 22.

[0027] Each of the pair of overhanging portions 62 protrudes from the lever body 61 in the shape of a small piece. The first cam surface 65 abuts against the second step portion 37 of the first member 31 of the outer lid 22 when the lever 24 is in the first position P1 in a state where the lever 24 is laid down relative to the outer lid 22. The second cam surface 66 abuts against the second step portion 37 of the first member 31 of the outer lid 22 when the lever 24 is in the second position P2 in a state where the lever 24 is upright relative to the outer lid 22. The second cam surface 66 is adjacent to the first cam surface 65. More specifically, the second cam surface 66 is smoothly connected to the first cam surface 65 via a connecting portion 67 having an arc shape. Here, the distance D1 from the bearing hole 64 to the first cam surface 65 is greater than the distance D2 from the bearing hole 64 to the second cam surface 66.

[0028] In this embodiment, the shaft 57 is provided on the arm 53 of the inner lid 23, and the bearing hole 64 is provided in the lever 24, but this arrangement is one example. It is also possible that the shaft 57 is provided on the lever 24, and the bearing hole 64 is provided in the arm 53 of the inner lid 23. The engagement shaft in the present invention is a concept that includes both the shaft 57 and the bearing hole 64.

[0029] 9, the spacer member 25 has a rectangular shape when viewed from the front and a bullet shape when viewed from the side, and is hollow inside. The spacer member 25 has a groove 71 into which the pair of rails 56 are fitted, and a hook hole 72 used when removing the spacer member 25 from the pair of rails 56. The spacer member 25 is interposed between the pair of protrusions 55 of the arm portion 53, and prevents the pair of protrusions 55 from bending, thereby preventing the inner lid 23 from falling off the lever 24 or the outer lid 22 unintentionally.

[0030] After removing the gasket 16 from the first mounting portion 46 and the second mounting portion 52, the user can remove the spacer member 25 from between the pair of protrusions 55 of the arm portion 53, thereby removing the inner lid 23 from the outer lid 22 and washing each part.

[0031] As shown in FIG. 10, the packing 16 is integrally formed from a rubber-like elastic body. The packing 16 is formed of, for example, silicone rubber, an elastomer material, synthetic rubber, or the like. In this embodiment, the packing 16 is attached to the lid 15. As shown in FIGS. 12, 13, 16, and 17, the packing 16 has a peak 73 having an arch-shaped cross section that is convex toward the inner surface of the container body 14, a first base 74 located at one base of the peak 73, a second base 75 located at the other base of the peak 73, a funnel 76 provided to protrude outward from the peak 73, and a hook 77 for removal that protrudes from the second base 75. The shape of the packing 16 is not limited to the above. The packing 16 may have a V-shaped cross section that is convex toward the inner surface of the container body 14, like a so-called bellows.

[0032] The peak portion 73 has a bellows-like shape composed of a single peak. The peak portion 73 can abut against the inner surface of the container body 14 at its top and its periphery. The first base portion 74 is formed in a ring shape and can be fitted into the first mounting portion 46. The second base portion 75 faces the first base portion 74. That is, the second base portion 75 is formed in a ring shape and can be fitted into the second mounting portion 52. The packing 16 also plays a role in connecting the outer lid 22 and the inner lid 23.

[0033] The funnel portion 76 is formed in an annular shape and protrudes from the ridge portion 73 in an obliquely upward direction so as to expand in a funnel shape. That is, as shown in Figs. 10, 16, and 17, the funnel portion 76 protrudes from the ridge portion 73 toward the opening end surface 13 of the container body 14 so as to expand in a funnel shape when the packing 16 is inserted inside the container body 14. The thickness dimension of the funnel portion 76 is extremely smaller than the thickness dimension of the ridge portion 73 and is formed thin. Therefore, the funnel portion 76 has a fin-like cross-sectional shape and can be easily deformed when subjected to an external force. In addition, when the packing 16 is housed in the container body 14, it can be closely attached to the inner surface of the container body 14 by following the inner surface of the container body 14. In this embodiment, when the lever 24 is in the first position P1, both the ridge portion 73 and the funnel portion 76 abut against the inner surface of the container body 14, and the area of ​​the part where the packing 16 is closely attached to the inner surface of the container body 14 can be made large. This makes it possible to keep the inside of the container body 14 airtight and liquidtight so that liquid does not leak out from the container body 14.

[0034] Next, the operation of attaching and detaching the lid body 15 to and from the container body 14 will be described with reference to Figs.

[0035] When the lid body 15 is removed from the container body 14, the lever 24 is set in advance to the second position P2 in which it stands up relative to the outer lid 22, as shown in Figs. 18 to 20. When the lever 24 is set to the second position P2, the lever 24 abuts the second cam surface 66 against the second step portion 37 of the first member 31 of the outer lid 22. At this time, as is clear from Fig. 8, the distance D2 from the bearing hole 64 to the second cam surface 66 is smaller than the distance D1 from the bearing hole 64 to the first cam surface 65, so that the inner lid 23 is moved (lowered) to a position separated from the outer lid 22. At this time, the pair of guide posts 54 of the inner lid 23 are guided by the pair of third through holes 44 of the second member 32, so that the inner lid 23 is lowered while maintaining a parallel state relative to the outer lid 22.

[0036] In this state, the distance between the first attachment portion 46 of the outer lid 22 and the second attachment portion 52 of the inner lid 23 is large, and therefore the distance between the first base portion 74 and the second base portion 75 of the packing 16 is also large. This causes the peak portion 73 to deform flat toward the inside, and the amount by which the peak portion 73 protrudes outward (toward the inner surface of the sealed container 11) becomes smaller. This causes the packing 16 to retreat from the inner surface 14A of the container body 14 when the lever 24 is in the second position P2.

[0037] With the lever 24 in the second position P2, the packing 16 is retracted from the inner surface 14A of the container body 14, so that the user can remove the lid body 15 from the container body 14 with a small amount of force.

[0038] On the other hand, when the lid body 15 is to be reattached to the container body 14, the lid body 15 is attached to the container body 14 with the lever 24 similarly in the second position P2. When the user attaches the lid body 15 to the container body 14 and fits the lid body 15 firmly into the container body 14, the abutment surface 35 of the lid body 15 abuts against the opening end surface 13 of the container body 14. Furthermore, as shown in Figures 14 and 15, the rib 21 of the container body 14 is inserted into the recess 35A of the lid body 15.

[0039] When the user seals the inside of the container body 14, as shown in Figs. 1, 12, and 13, the lever 24, which is in the second position P2, is moved to the first position P1, which is laid down sideways with respect to the lid body 15. As a result, the lever 24 abuts against the second step portion 37 of the first member 31 of the outer lid 22 with the first cam surface 65. At this time, as is clear from Fig. 8, the distance D1 from the bearing hole 64 to the first cam surface 65 is greater than the distance D2 from the bearing hole 64 to the second cam surface 66, so that the inner lid 23 is moved (raised) to a position close to the outer lid 22. At this time, the pair of guide posts 54 of the inner lid 23 are guided by the pair of third through holes 44 of the second member 32, so that the inner lid 23 rises while maintaining a parallel state with respect to the outer lid 22.

[0040] In this state, the distance between the first mounting portion 46 of the outer lid 22 and the second mounting portion 52 of the inner lid 23 is small, so the distance between the first base portion 74 and the second base portion 75 of the packing 16 is also small. As a result, the ridge portion 73 is deformed so as to protrude outward, and the amount of protrusion of the ridge portion 73 outward (toward the inner surface 14A of the sealed container 11) increases. Therefore, the packing 16 abuts against the inner surface of the container body 14 at the ridge portion 73. At the same time, the funnel portion 76 of the packing 16 is in close contact with the inner surface of the container body 14. Therefore, the packing 16 is in close contact with the inner surface of the container body 14 over a large area at both the ridge portion 73 and the funnel portion 76. This allows the inside of the container body 14 to be sealed in an airtight and liquidtight state.

[0041] At this time, the outer peripheral surface 35B of the recess 35A of the lid 15 engages with the outer surface of the rib 21 of the container body 14, correctly holding the lid 15 in the center of the container body 14, ensuring airtightness and preventing the container body 14 from deforming outward. This makes it possible to more reliably seal the sealed container 11.

[0042] When the user wants to disassemble and clean the lid 15, the user can grasp and pull the hook portion 77 of the packing 16 to remove the packing 16 from the lid 15. The removed packing 16 can be washed as needed.

[0043] With the packing 16 removed, the spacer member 25 is removed from between the pair of protruding pieces 55 of the arm portion 53 using a tool such as a flathead screwdriver. This allows the pair of protruding pieces 55 to bend inward. In this state, the lever 24 is removed from the arm portion 53, and the pair of protruding pieces 55 of the arm portion 53 are removed while being bent inward from the first through hole 38 of the first member 31 and the second through hole 43 of the second member 32, thereby allowing the inner lid 23 to be removed from the outer lid 22. Furthermore, the second member 32 of the outer lid 22 can be separated from the first member 31. In this way, the user can wash each part of the lid body 15 in a disassembled state as appropriate. When reassembling the lid body 15, the above procedure can be reversed.

[0044] According to this embodiment, the following can be said: The sealed container 11 includes a container body 14 having an opening end surface 13, a lid body 15 covering the opening end surface 13, and an annular packing 16 that seals a gap between an inner surface 14A of the container body 14 and the lid body 15 in the vicinity of the opening end surface 13, the packing 16 having an arch-shaped or V-shaped cross section that is convex toward the inner surface 14A and that can abut against the inner surface 14A, a first base portion 74 located at one base of the ridge portion 73, and a second base portion 75 located at the other base of the ridge portion 73. The lid body 15 has an outer casing 46 having an abutment surface 35 that abuts against the opening end surface 13 and a first attachment portion 46 that is provided inside the abutment surface 35 and to which the first base portion 74 is attached. The container body includes a lid 22, an inner lid 23 located inside the container body 14, the inner lid 23 having an inner lid body 51, a second mounting portion 52 provided on the inner lid body 51 and having a second base portion 75 attached thereto, and an arm portion 53 extending from the inner lid body 51 and penetrating the outer lid 22, and a lever 24 provided on the outside of the container body 14, connected to the inner lid 23 via the arm portion 53, and capable of raising and lowering the inner lid 23 by rotating while abutting against the outer lid 22, the lever 24 being rotatable between a first position P1 in which the inner lid 23 is raised and the peak portion 73 is abutted against the inner surface 14A, and a second position P2 in which the inner lid 23 is lowered and the peak portion 73 is retracted from the inner surface 14A.

[0045] According to this configuration, by setting the lever 24 to the first position P1, the distance between the first base 74 and the second base 75 can be reduced, and the peaks 73 of the packing 16 can be deformed to protrude significantly toward the inner surface 14A. This allows the peaks 73 of the packing 16 to abut against the inner surface 14A, sealing the inside of the sealed container 11. Also, by setting the lever 24 to the second position P2, the distance between the first base 74 and the second base 75 can be increased, and the peaks 73 of the packing 16 can be deformed to retract from the inner surface 14A. This allows the lid 15 to be removed from the container body 14 with an extremely small amount of force.

[0046] The container body 14 has a first step protruding from the open end surface 13, and the lid body 15 has a second step protruding from the abutment surface 35, the second step being engageable with the first step.

[0047] According to this configuration, the lid 15 can be properly held in the center of the container body 14, ensuring airtightness, and preventing deformation of the container body 14 due to pressure from the inside by the packing 16. This further improves the airtightness of the sealed container 11.

[0048] The inner lid 23 has a pair of guide posts 54 on both sides of the arm portion 53, and the outer lid 22 has a pair of recesses on the surface facing the inner lid 23, each of which has a shape complementary to the guide posts 54 and is capable of guiding the received guide posts 54.

[0049] This configuration allows the inner lid 23 to rise and fall more smoothly. This allows the packing 16 to deform more smoothly, and reduces the force required to operate the lever 24, making the sealed container 11 more user-friendly.

[0050] The packing 16 has a funnel portion 76 that protrudes from the ridge portion 73 toward the opening end face 13 so as to expand in a funnel shape, and the funnel portion 76 is formed with a thickness dimension smaller than the thickness dimension of the ridge portion 73.

[0051] According to this configuration, the funnel portion 76 can increase the contact area between the ridge portion 73 and the inner surface 14A of the container body 14, and the packing 16 can reliably ensure airtightness and watertightness.

[0052] The lever 24 has an engagement shaft portion 57 that engages with the arm portion 53, a first cam surface 65 that abuts against the outer lid 22 when in the first position P1, and a second cam surface 66 that is adjacent to the first cam surface 65 and has a distance from the engagement shaft portion smaller than the distance from the engagement shaft portion 57 to the first cam surface 65, and the second cam surface 66 abuts against the outer lid 22 when in the second position P2.

[0053] According to this configuration, the inner lid 23 can be raised at the first position P1 and lowered at the second position P2 with an extremely simple structure using a cam. This allows the manufacturing cost of the sealed container 11 to be reduced.

[0054] The above-described embodiment can be implemented with various substitutions and modifications. Of course, the above-described different embodiments can be appropriately combined to form one invention. [Explanation of symbols]
