Detailed Description

Fig. 1 is a perspective view of a container 10 of an embodiment. The container 10 is used for food preservation and small food storage. The container 10 includes a container body 12, a lid 14, a lock structure 16, a hinge 18, and a handle 20.

The container body 12 is formed in a bottomed cylindrical shape having an upper end open, and is formed of a glass material or a resin material. The container body 12 is not limited to a cylindrical shape, and may be formed in a square cylindrical shape.

The lid 14 is formed in a disk shape and is provided to be able to open and close the opening of the container body 12. The lid portion 14 adopts a closed state in which the opening of the container body portion 12 is closed and an open state in which the opening of the container body portion 12 is opened. A sealing member for sealing the opening of the container body 12 is attached to the lid 14. The lid portion 14 is formed of a glass material or a resin material, as in the case of the container body portion 12.

The hinge 18 rotatably connects the lid 14 to the container main body 12. The hinge 18 allows the opening and closing operation of the container body 12 to be performed in a state where the lid 14 is coupled to the container body 12.

The lock structure 16 locks the lid portion 14 in a state where the lid portion 14 closes the opening of the container body portion 12, and maintains the lid portion 14 in the closed state. The lock structure 16 adopts a locked state in which the lid portion 14 is locked in the closed state and an unlocked state in which the locking is released. In fig. 1, the lid 14 is in a closed state and the lock structure 16 is in a locked state. The detailed structure of the lock structure 16 and the hinge portion 18 will be described later. The handle portion 20 is formed of a wire material and is rotatably connected to the container body 12 side.

Fig. 2 is a side view of the container 10 with the lid portion 14 in an open state. The lid portion 14 opens the opening 22 of the container body portion 12, and is connected to the container body portion 12 by the hinge portion 18 in the opened state.

The locking structure 16 has a latch portion 24, a hook portion 26, and an engagement portion 28. The latch portion 24 is rotatably provided on the cover portion 14 side. The hooking portion 26 is rotatably provided to the latch portion 24. The engaging portion 28 is provided in the container body 12, and engages with the hook portion 26 to be in a locked state. In fig. 2, the engagement portion 28 and the hook portion 26 are not engaged with each other, and thus the lock release state is obtained.

Fig. 3(a) is a rear view of the container 10, and fig. 3(b) is a front view of the container 10. Fig. 4(a) is a side view of the container 10, and fig. 4(b) is a plan view of the container 10. Fig. 3(a), 3(b), and 4(a) show the container body 12 without a part thereof.

As shown in fig. 3(a), a pair of

first wires

30a and 30b is provided in the lid-side groove portion 14a of the lid portion 14 so as to wrap the lid portion 14, and a second wire 32 is provided in the body-side groove portion 12a of the container body 12 so as to wrap the container body 12. The body-side groove 12a and the lid-side groove 14a are formed annularly in the circumferential direction. The

first wires

30a and 30b and the second wire 32 will be described with reference to the new drawings.

Fig. 5(a) is a plan view of the first wire 30a, fig. 5(b) is a side view of the first wire 30a, and fig. 5(c) is a rear view of the first wire 30 a. The first wire 30b shown in fig. 3(a) has a symmetrical shape to the first wire 30a, and has the same configuration, and therefore, the description thereof is omitted. The cover-side groove portion 14a of the cover 14 is surrounded by a first wire 30a and a first wire 30b (referred to as "first wires 30" without distinguishing between them).

The first wire 30a is formed of a metal material in an arc shape, and has a support portion 42 at one end and a bearing portion 40 at the other end. The support portion 42 is formed to protrude toward the front side. The pair of support portions 42 of the first wire 30a and the first wire 30b rotatably support the latch portion 24.

As shown in fig. 5(b), the bearing portion 40 is formed to extend to the back surface side and hang down, and is bent to form a circle. The pair of bearing portions 40 of the first wire 30a and the first wire 30b are connected to the second wire 32 to form the hinge portion 18, and rotatably support the lid portion 14.

Fig. 6(a) is a side view of the second wire 32, and fig. 6(b) is a top view of the second wire 32. The second wire 32 is formed of a metal material in a ring shape having a slit. The second wire 32 has an engaging portion 28, a handle support portion 36, and a shaft support portion 38. The handle support portion 36 is formed in a hole shape, and is connected to and supported by the end portion 20a of the handle portion 20.

The engaging portion 28 includes a protruding portion 28a protruding from the main body to the front side, and a hanging portion 28b hanging from an end of the protruding portion 28 a. The protruding portion 28a is bent from the main body of the second wire 32 and protrudes radially outward. The hanging portion 28b is formed in a substantially U shape in front view, and extends away from the container body 12 toward the front end, i.e., hangs down so as to protrude toward the front side. This facilitates the hook 26 to be hooked on the hanging portion 28 b.

The pair of shaft support portions 38 are provided, and extend from the main body of the second wire 32 to the back surface side. The shaft support portion 38 is inserted into the bearing portions 40 of the

first wires

30a and 30b to form the hinge portion 18. In order to restrict the separation of the pair of shaft support portions 38, the first annular portion 34 is provided on the base end side of the shaft support portion 38. A pair of shaft support portions 38 are inserted through the first annular portion 34.

Returning to fig. 3 and 4. Fig. 3(a) shows a case where the handle portion 20 is supported by the handle support portion 36. Fig. 4(a) and 4(b) show a case where the shaft support portion 38 of the second wire 32 is coupled to the bearing portions 40 of the first wire 30a and the first wire 30 b. The hinge 18 is formed by connecting a first wire 30 on the container body 12 side and a second wire 32 on the lid 14 side.

As shown in fig. 4(b), the pair of shaft support portions 38 are inserted into the pair of bearing portions 40 from the outside, but since the pair of shaft support portions 38 are separated, when the pair of bearing portions 40 are moved toward the inside of the pair of shaft support portions 38, the coupling between the bearing portions 40 and the shaft support portions 38 is released. When the user grasps the lid portion 14 so as to bring the pair of bearing portions 40 close to each other in the open state of the lid portion 14 shown in fig. 2, the hinge portion 18 is disconnected from each other, and the lid portion 14 can be removed from the container main body portion 12. Since the latch portions 24 are provided on the lid portion 14 side, the container body portion 12 has a simple shape and is easy to use when the lid portion 14 is removed.

The embodiment in which the hole-shaped bearing portions 40 are provided in the

first wires

30a and 30b and the rod-shaped shaft support portions 38 are provided in the second wire 32 is shown, but the embodiment is not limited thereto, and the relationship between the hole shape and the rod shape may be reversed. In any case, the hinge portion 18 can release the connection of the first wire 30 and the second wire 32.

As shown in fig. 4(a), the lock structure 16 is composed of a latch portion 24, a hooking portion 26, and an engaging portion 28. The latch portion 24 and the hook portion 26 will be described with reference to the new drawings.

Fig. 7(a) is a side view of the latch portion 24, and fig. 7(b) is a front view of the latch portion 24. The latch portion 24 has a first rotation shaft portion 24a, a second rotation shaft portion 24b, and an operation portion 24c, and is formed in a long shaft shape based on a metal plate material. The first rotation shaft 24a is formed in a hole shape in a side wall of the latch 24, and is positioned midway in the longitudinal direction (the left-right direction in fig. 7 (a)) of the latch 24, and receives the support portion 42 of the first wire 30a and the first wire 30 b.

The second rotation shaft 24b is formed in a hole shape at one end of the latch portion 24 in the longitudinal direction. The second rotation shaft portion 24b rotatably supports the hook portion 26. The first rotation shaft 24a and the second rotation shaft 24b are parallel to each other, but are positioned at different positions.

The operating portion 24c is located on the other end side of the latch portion 24 in the longitudinal direction. The operation portion 24c receives an operation with a finger of the user, and the latch portion 24 is rotated by the first rotation shaft portion 24a by the operation.

Fig. 8(a) is a front view of the hook 26, and fig. 8(b) is a side view of the hook 26. The hook 26 is formed of a wire material and is formed in a rectangular loop shape. The hook 26 has a curved portion 26a, a shaft portion 26b, and a tip portion 26 c. The shaft portions 26b are provided in a pair separated by a gap, and are pivotally supported by the second rotating shaft portion 24 b. The shaft portion 26b is located at the base end, and faces the tip end portion 26 c. The distal end portion 26c is hooked to the engaging portion 28.

The bent portion 26a bends the hook portion 26 at a midpoint between the shaft portion 26b and the distal end portion 26c in a side view. The bent portion 26a bends the hook portion 26 at the shaft portion 26b from the center in a side view. In the closed state of the lid portion 14, the hook portion 26 is disposed away from the container body portion 12 toward the distal end portion 26c through the bent portion 26 a. The hook portion 26 is bent outward in the radial direction, which is a direction away from the engagement portion 28, toward the front end portion 26c in a side view of the closed state and the unlocked state of the lid portion 14.

Returning to fig. 4. The latch portion 24 is provided so as to be located on the side of the cover portion 14, i.e., on the radially outer side of the cover portion 14 in the locked state, and the operating portion 24c is provided so as to hang down. That is, the latch portion 24 is in a state of drooping from the lid portion 14 side toward the container body portion 12 side in the locked state. As shown in fig. 4(a), when the latch portion 24 rotates about the first rotation shaft portion 24a, the second rotation shaft portion 24b serving as a fulcrum of the hook portion 26 is disposed away from the first rotation shaft portion 24a, and therefore rotates about the first rotation shaft portion 24 a.

The latch portion 24 is provided so as to be located on the side of the cover portion 14 in the locked state shown in fig. 4(a) and so as not to go over the upper end surface of the cover portion 14. This can simplify the shape of the upper surface of the lid 14 into a flat shape, and can easily place another object on the lid 14.

Fig. 9 is a diagram for explaining the operation of the lock structure 16. The locking structure 16 in the a state and the locking structure 16 in the B state are shown with different rotational positions of the latch portion 24. The B state is a state in which the latch 24 cannot rotate in the opening direction, and is a state in which the latch 24 is maximally opened. The state a is a state in which the latch portion 24 is rotated from the state B in the closing direction, and is a state before the latch portion 24 is locked.

In the state B, the end portion of the latch portion 24 on the second rotation shaft portion 24B side abuts against the support portion 42 of the first wire 30a, 30B to restrict the rotation of the latch portion 24 in the opening direction. Further, the latch portion 24 abuts on the lid portion 14 to restrict rotation of the latch portion 24 in the opening direction. On the other hand, as shown in fig. 4(a), the latch portion 24 abuts against the engaging portion 28 when rotated in the closing direction to restrict the rotation, and does not abut against the container body 12. This can prevent the latch portion 24 from coming into contact with the container main body portion 12 and being damaged.

The hook portion 26 is in a state of hanging down from the second rotation shaft portion 24b by its own weight, and moves in conjunction with the rotation of the latch portion 24, and approaches or separates from the engagement portion 28. In the B state where the latch portion 24 is maximally opened, the front end portion 26c of the hooking portion 26 is at a position not overlapping the engaging portion 28 in the vertical direction. Therefore, even if the lid portion 14 is rotated in the opening direction, the hook portion 26 cannot be hooked to the engagement portion 28. The hook portion 26 in the B state can be in a free state in which no external force is applied, only by hanging from the second rotation shaft portion 24B.

More preferably, the distance L between the tip end 26c of the hook 26 and the tip end of the engagement portion 28 is set to be equal to or greater than a predetermined open distance in the state B in which the latch 24 is maximally opened. Therefore, when the lid 14 is opened from the B state, the hook portion 26 cannot be hooked to the engagement portion 28 even if it slightly swings. The predetermined interval is set to, for example, about 5mm to 10 mm.

The hook 26 extends from the curved portion 26a toward the distal end portion 26c in a direction away from the container body 12. By providing the bent portion 26a, the distal end portion 26c is located at a position farther from the container body 12, i.e., a position farther from the engaging portion 28, than the second rotation shaft portion 24b in the radial direction. The radial direction is a direction from the central axis of the container body 12 toward the engaging portion 28. This makes it possible to easily disengage the hook 26 from the engaging portion 28, and if the user rotates the latch portion 24 in the opening direction, the tip 26c of the hook 26 is radially separated from the engaging portion 28, so that the operation of removing the hook 26 with a finger is not required.

In the locked state shown in fig. 4(a), by rotating the latch portion 24 in the opening direction, the hooking portion 26 is disengaged from the engaging portion 28 in conjunction with the latch portion 24, and is moved to a position not interfering with the engaging portion 28, that is, a position radially outward of the engaging portion 28, thereby obtaining a position in a state B shown in fig. 9.

In the state a in which the latch portion 24 is rotated in the closing direction, the tip end portion 26c is positioned to overlap the engaging portion 28 in the vertical direction and enters below the engaging portion 28. Thus, the hook portion 26 can be hooked to the engagement portion 28 by simply rotating the latch portion 24 in the closing direction without pulling the hook portion 26 with a finger.

In the unlocked state B, the latch pin portion 24 is rotated in the closing direction, and the hooking portion 26 moves in conjunction with the latch pin portion 24 to a position where it can engage with the engaging portion 28, that is, a position below the engaging portion 28. When the latch portion 24 is rotated in the closing direction from the state a, the tip end portion 26c of the hook portion 26 is hooked to the engaging portion 28, and the locked state shown in fig. 4(a) is achieved. Thus, the user can lock and unlock the lock structure 16 by simply rotating the latch portion 24.

The present invention is not limited to the above-described embodiments, and various modifications such as design changes may be added to the embodiments based on the knowledge of those skilled in the art, and the embodiments to which such modifications are added are also included in the scope of the present invention.
