Description

  The present invention is suitable for long-term storage of contents such as foodstuffs, and relates to a sealed container that can provide a strong seal without displacement even when the opening is a flat container.

  Cylindrical sealed containers are known that are suitable for long-term storage of contents such as foodstuffs and that can provide a strong seal only by lever collapse. The sealed container includes a lid portion that is attached to the upper opening of the container body. The lid portion has an upper lid, an inner lid that rotatably attaches a rubber seal to a side surface, and rotatably supports a base end portion of a lever. After attaching the lid to the container body, tilting the lever raises the inner lid to the outer lid side, and the tip of the inner plate formed on the outer lid pushes the vicinity of the tip of the rubber seal downward The rubber seal is expanded in diameter by the pushing, and the sealing force is increased. Since such a sealed container is circular in both the lid and the rubber seal, there is little occurrence of a shift that affects the sealing performance when the lid is attached to the container body.

  In recent years, kitchen products having excellent design properties have been demanded. Even in a sealed container, if it is a flat container, side-by-side storage can be performed efficiently, which is convenient. In view of this, there has been a demand for the development of a material that has been used in a cylindrical sealed container and has excellent sealing properties by a one-touch operation by raising or tilting the lever.

  However, when the one-touch operation by raising and lowering the lever, which has been used for cylindrical sealed containers so far, is applied to a flat container, there are a longitudinal direction and a short direction. When the lid is mounted, a shift occurs in the longitudinal direction. Even if the lever is fallen down in this state of deviation, there is a problem that a rubber seal hits the inner wall of the container and a sufficient sealing effect cannot be obtained. Therefore, even with a flat (substantially rectangular) container, the rubber seal does not come into contact with each other, and development of a container capable of obtaining a strong seal has been awaited.

  Accordingly, an object of the present invention is to provide a sealed container in which a rubber seal does not come into contact with each other even in a flat (substantially rectangular) container and a strong sealing property can be obtained.

Accordingly, the present invention solves the above-described conventional problems, and includes a container body (A) having an upper opening having a substantially rectangular shape in plan view, and a lid (B) attached to the upper opening of the container body. Prepared,
The lid portion (B) includes a lever (b1) having a lever side shaft support portion,

An inner lid side shaft support portion standing at the center of the surface, a side groove into which the rubber seal fits, an inner lid (b3) having an upright portion for preventing deviation standing up from the surface, and an annular shape fitted into the side groove of the inner lid Rubber seal (b4)
In the state where the lever is raised, the tip of the standing portion and the bottom surface of the upper lid are separated from each other,
By closing the lever, the inner lid is pulled up to the upper lid side, the tip of the inner plate pushes the vicinity of the tip of the rubber seal downward, and the rubber seal expands in diameter by the pushing. Is to provide.

  Further, the present invention provides the sealed container characterized in that, in a sealed state in which the lever is tilted, the tip of the upright portion and the bottom surface of the upper lid are in a contact state or a non-contact state. .

Further, according to the present invention, the lever side shaft support portion has a base frame body having a shaft or a shaft hole protruding sideways, and the center frame body from the center of the shaft or the shaft hole in the standing state of the lever. A length l ¹ to the end in the up-down direction is smaller than a length l ² from the center of the shaft or the shaft hole to the end in the up-down direction in the lying state of the lever. To do.

  In addition, the present invention provides the sealed container characterized in that a lever end abutting surface with which the tip of the base frame body of the lever abuts is provided in the vicinity of the central through hole of the upper lid.

  Further, the present invention provides the sealed container, wherein the rubber seal is an annular body, and includes an inner mounting portion and an inclined portion extending obliquely upward from an outer peripheral end of the mounting portion. It is to provide.

  In addition, the present invention provides the sealed container, wherein the substantially rectangular shape of the upper opening has rounded corners or curved sides forming the rectangle.

  In addition, the present invention provides the sealed container characterized in that, in a state where the lever is erected, the tip of the erected portion and the bottom surface of the upper lid are separated from each other by 2 mm to 6 mm.

  Further, the present invention provides the sealed container, wherein the tip of the upright portion and the bottom surface of the upper lid are spaced from each other by 0.1 to 0.8 mm in a state where the lever is laid down. Is.

  According to the present invention, when the lid is attached to the container body, the axis of the container body and the axis of the lid are offset in the vertical direction (particularly, an inclined posture appears in the longitudinal direction of the inner lid). Even if it is installed, the upright part for preventing the slippage of the inner lid comes into contact with the back surface of the upper lid and prevents further deviation. Inside, the rubber seal and the inner wall of the container body become a strong seal without being biased.

  Next, a sealed container according to an embodiment of the present invention will be described with reference to FIGS. FIG. 2 is shown with a part cut away so that the structure near the through hole can be easily understood. The sealed container 10 includes, for example, a container main body 1 having an upper opening that is substantially rectangular in plan view and a lid 2 that is attached to the upper opening of the container main body 1. No. 2 rubber seal 6 is in strong contact with the inner wall of the container and is suitable for long-term storage of contents. If the container main body 1 has a substantially rectangular upper opening in a plan view, it is convenient to store a plurality of adjacent containers.

  In the sealed container 10, the lid portion 2 includes a lever 5, an upper lid 4, an inner lid 3, and a rubber seal 6. The lever 5, the upper lid 4, the inner lid 3, and the rubber seal 6 are separate members, and are assembled to constitute the lid portion 2. The substantially rectangular shape of the upper opening of the sealed container 10 means that the corners of the rectangle are rounded, or the sides forming the rectangle are curved.

The lever 5 includes a plate-like lever main body 513 and a lever side shaft support portion 51. When the contents in the container are stored for a long time, the lever 5 is in a lying state, and the lever 5 is raised when the contents are taken out. The lever-side shaft support portion 51 is a base frame body having a pair of substantially plate-like bodies 511 and 511 opposed to each other on the inner surface, and the rear surface of the pair of substantially plate-like bodies 511 and 511 has a shaft of the inner lid side shaft support portion 34. It has a shaft hole 517 into which the protrusions 34 and 34 fit. The length l ¹ from the center of the shaft hole 517 in the standing state of the lever 5 to the end in the vertical direction is smaller than the length l ² from the center of the shaft hole 517 to the end in the vertical direction in the lying state of the lever 5. . Further, the end portion 516 contacts the lever end contact surface 433 in the standing state, and the end portion 515 contacts the lever end contact surface 433 in the lying state. As a result, the lever 5 is raised from the lying down state, thereby pulling up the inner lid 3 to the upper lid 4 side.

  The upper lid 4 has an upper lid portion 41 having a contact surface portion 445 in contact with the upper end edge portion 11 of the container main body 1 on the back surface, and extends downward from the back surface 446 of the upper lid portion 41 inside the contact surface portion 445. It has an annular inner plate 42 and a through hole 444 through which the inner lid side shaft support portion 34 that is axially fitted to the lever side shaft support portion 51 passes. Since the contact surface portion 445 contacts the upper end edge portion 11 of the container main body 1, the container main body 1 receives and supports a downward inferior force when raising the lever 5. The outer peripheral shape of the upper lid 41 in plan view is the same as the outer peripheral shape of the container main body in plan view, and the outer peripheral shape of the inner plate 42 in plan view is smaller than the outer peripheral shape of the container main body in plan view. Shape.

  The inner plate 42 has a size that surrounds the inner lid 3 in a plan view. When the lever 5 stands up, the tip of the inner plate 42 does not push the rubber seal 6, and when the lever 5 falls down, the tip of the inner plate 42 is an inclined portion 63 of the rubber seal 6. push. For this reason, the diameter of the rubber seal 5 is increased and the inner wall 12 of the container is strongly pressed (see FIGS. 17 and 18).

  The through hole 444 is a hole through which the inner lid side shaft support portion 34 that is fitted to the lever side shaft support portion 51 passes. Further, on the upper surface of the upper lid 41 including the through hole 444, there is a lever accommodating portion 43 for accommodating the lying lever 5. Support side plates 432 and 432 for guiding the position of the lever side shaft support portion 51 are attached to one side end of the through hole 444. The support side plates 432 and 432 are located inside the pair of substantially plate-like bodies 511 and 511, and form a gap in cooperation with the inner wall of the lever housing portion 43, thereby preventing lateral blurring when the lever 5 is rotated. To do. Further, a lever main body abutting surface 431 for accommodating the lying lever main body 513 is formed from the support side plates 432 and 432 to the end of the upper lid 4. As a result, when the lever 5 is in the lying down state, the upper surface of the upper lid 4 is flush with no protrusion.

  Further, a lever end abutting surface 433 is provided around the central through hole 444 of the upper lid 4, and in this example, on both sides in the lateral direction, with which the tip of the base frame body 51 of the lever 5 abuts. Since the lever end contact surface 433 is formed on the upper lid 4, the lever end contact surface 433 does not move downward while being installed in the container body 1. Therefore, when the standing lever 5 is tilted, the tip of the base frame 51 of the lever 5 serves as a support portion that supports the pushing force when the lever end contact surface 433 is strongly pushed downward.

  The middle lid 3 stands upward from the surface on both sides in the longitudinal direction of the pair of middle lid side pivot support portions 31, the side groove 32 into which the rubber seal 6 fits, and the pair of middle lid side pivot support portions 31 standing at the center of the surface. It has standing parts 33 and 33 for preventing slippage. The pair of inner lid side shaft support portions 31 have shafts 34 protruding outward on both outer side surfaces on the distal end side of the substantially plate-shaped main body. The shaft 34 is fitted in the shaft hole 517 of the lever side shaft support portion 51. In this example, the upright portions 33 and 33 are plate-like bodies extending in the short-side direction, but are not limited thereto, and may be one or a plurality of protrusions. An annular wall surrounding 31 may be used.

  The sealed container 10 has a rubber seal 6 having a longitudinal direction. For this reason, when attaching the cover part 2 to the container main body 1, it is easy to produce a shift | offset | difference in a longitudinal direction. For this reason, the sealed container 10 is configured to make the displacement between the upper lid 41 and the inner lid 3 as small as possible even if the longitudinal displacement occurs. Therefore, when the lid 2 is mounted on the container body 1 and the lever 5 is raised, the tip (upper end) of the standing portion 33 and the bottom surface 446 of the upper lid 4 are slightly separated from each other, and the lever 6 is closed and sealed. In the state, the tip of the standing portion 33 and the bottom surface of the upper lid 4 are in contact with each other or in a non-contact state having a very small gap. Specifically, in the state where the lever 5 is erected, the tip of the erected portion 33 and the bottom surface 446 of the upper lid 4 are separated by 2 mm to 6 mm, and the erected portion 33 is in a state where the lever 6 is laid down. Are preferably separated from the bottom surface 446 of the upper lid 4 by 0.1 to 0.8 mm, particularly 0.1 to 0.4 mm. The side groove 32 is a groove into which the annular rubber seal 6 is fitted, and is a groove having a rectangular cross section in the present embodiment, which is formed on the side surface of the inner lid 3 and in the circumferential direction.

  The rubber seal 6 is an annular body, and includes an inner mounting portion 61 and an inclined portion 62 that extends obliquely upward from the outer peripheral end of the mounting portion 61. The tip of the inclined portion 62 is a horizontal end 63. The rubber seal 6 tilts the lever 5 so that the inner lid 3 is pulled up to the upper lid side, and the tip of the inner plate 42 pushes the vicinity of the tip of the rubber seal 6 downward, and the diameter is expanded by the pushing. The expanded diameter of the rubber seal 6 means that the inclined portion 62 of the rubber seal 6 is pushed downward, so that the inclined portion 62 bends downward and its tip extends outward. The outer dimensions of the rubber seal 6 are substantially the same as the inner shape of the container body 1. And the diameter with the push-in increases, and the seal with the container inner wall 12 becomes strong.

  Next, a method for assembling the sealed container 10 will be described with reference to FIGS. As shown in FIG. 9, the inner lid 3 is positioned below the upper lid 4, and the pair of middle lid side pivot support portions 31 of the inner lid 3 are passed through the through holes 444 of the upper lid 4 (FIG. 10). Note that the upper lid 4 and the inner lid 3 in the state shown in FIG. 10 are not locked or engaged, and are held in a state of being attached by hand. Next, the lever 5 is positioned above the upper lid 4, and the shaft hole 517 of the base frame body 51 of the lever 5 and the shaft protrusion 34 of the pair of middle lid side shaft support portions 31 of the inner lid 3 are locked. Accordingly, the lever 5 is rotatable with respect to the pair of middle lid side shaft support portions 31 of the inner lid 3. As shown in FIG. 12, the end portion 515 of the base frame 51 of the lever 5 is in contact with the lever end contact surface 433 of the upper lid 4 when the lever 5 is in a lying state.

  Next, the rubber seal 6 is positioned below the inner lid 3 and fitted into the side groove 32 of the inner lid 3 (FIGS. 14 and 15). In this state, the tip of the rubber seal 6 is positioned slightly above the upper surface 35 of the inner lid 3. Further, the position of the inclined portion 62 of the rubber seal 6 where the tip of the inner lid 3 hits is also located slightly above the upper surface 35 of the inner lid 3. Thereby, when the inner lid 3 is pulled up, the tip of the inner plate 42 pushes the inclined portion 62 of the rubber seal 6. Thus, the lid | cover part 2 shown in FIG.14 and FIG.15 is obtained by mounting | wearing with the rubber seal 6. FIG. In addition to the above, the lid 2 may be formed by, for example, a method in which the rubber lid 6 is attached to the inner lid 3, the upper lid 4 and the inner lid 3 are assembled, and then the lever 5 is attached.

Next, a method for assembling the sealed container 10 will be described with reference to FIGS. That is, the lid 2 shown in FIGS. 14 and 15 is attached to the container body 1. At this time, the lever 5 is in a standing state. When the lever 5 is in the standing state, the tip of the inner plate 42 is close to or abutting without pressing the rubber seal 6. For this reason, the inner lid 3 to which the rubber seal 6 is attached can be smoothly inserted into the container body 1. Further, the end portion 516 of the base frame body 51 of the lever 5 is in contact with the lever end contact surface 433. In this case, the length from the axial center of the base frame 51 of the lever 5 to the end in the vertical direction is l ¹ . Further, the contact surface portion 445 of the upper lid 4 is in contact with the upper end edge portion 11 of the container body 1. For this reason, the cover part 2 is the state mounted on the container main body 1, and can be removed easily. In addition, the front-end | tip of the standing part 33 of the inner cover 3 and the back surface of the upper cover 4 are spaced apart with a slight gap. For this reason, it is possible to prevent the displacement without becoming an obstacle to raising the inner lid 3.

Next, the lever 5 is laid down. As the lever 5 rotates, the end portion 515 of the base frame 51 of the lever 5 comes into contact with the lever end contact surface 433 of the upper lid 4. At this time, the length from the axial center of the base frame 51 of the lever 5 to the end in the vertical direction is a length l ² larger than l ¹ . As a result, the lever 5 pushes down the upper lid 4, but the upper lid 4 is in a state of being placed on the container body 1, and therefore cannot move downward, and as a result, the inner lid 3 is pulled up. Thereby, the tip of the inner plate 42 of the upper lid 4 pushes the inclined portion 62 of the rubber seal 6. When the inclined portion 62 of the rubber seal 6 is pushed downward, the inclined portion 62 bends downward and its tip extends outward, improving the sealing performance between the rubber seal 6 and the inner wall 12 of the container main body 1. For this reason, the container and the outside (inside the room) are strongly blocked, and the contents can be stored for a long time. It should be noted that the tip of the standing portion 33 of the inner lid 3 and the back surface of the upper lid 4 have a very small gap or are slightly in contact with each other. Thereby, the standing part 33 does not affect the upward movement of the inner lid 3.

  The sealed container 10 is substantially rectangular in plan view. For this reason, for example, when the lid portion 2 is attached to the container body 1, there may be a deviation in which the inner lid 3 is inclined in the longitudinal direction as shown in FIG. 19. Since the sealed container 10 of the present example has the upright portion 33 on the upper surface of the inner lid, when such a deviation occurs, the tip of the upright portion 33 hits the back surface of the upper lid 4, so that further deviation may occur. Absent. That is, the sealed container 10 can prevent a deviation that adversely affects the sealing performance, although it allows a slight displacement that does not adversely affect the sealing performance.

  For example, in the sealed container 100 shown in FIG. 19 in which the standing portion 33 is not formed on the inner lid 300, when the lid portion 200 is attached to the container main body 1, a deviation that is inclined in the longitudinal direction occurs in the inner lid 300. Large deviation occurs. In this state, when the lever 500 is tilted, the tip of the rubber seal 600 cannot hit the inner wall of the container body 1 evenly, and a strong seal cannot be expected.

Next, when taking out the contents from the container body 1, the lying lever 5 is raised. As the lever 5 rotates, the end portion 512 of the base frame 51 of the lever 5 comes into contact with the lever end contact surface 433 of the upper lid 4. At this time, the length from the axial center of the base frame 51 of the lever 5 to the end in the vertical direction is a length l ¹ smaller than l ² . Thereby, the inner lid 3 is pulled down. Thereby, the tip of the inner plate 42 of the upper lid 4 is separated from the inclined portion 62 of the rubber seal 6. When the rubber seal 6 is restored to its original shape, the adhesion between the rubber seal 6 and the inner wall 12 of the container body 1 becomes weak, and the lid 2 can be smoothly removed from the container body 1.

  The sealed container of the present invention is not limited to the above embodiment, and various modifications can be made. For example, the back surface shape of the upper lid 4 is not limited to the back surface shape of FIG. 3. For example, the inner surface of the upper lid 4 may be deeply cut leaving the contact surface portion 445. In this case, the outer peripheral portion of the upper lid has an annular side plate shape (substantially similar to the annular inner plate) having the thickness of the contact surface portion 445. Further, the back surface shape on the inner side of the inner plate 42 is not limited to a flat shape, and may be a rib structure with vertical reinforcing ribs or horizontal reinforcing ribs. Moreover, the shaft hole 517 formed in the back surface of a pair of substantially plate-shaped body 511,511 may be a shaft protrusion. In this case, a shaft hole is formed in the inner lid side shaft support portion 34.

  In the case of a sealed container with a substantially rectangular shape in plan view, when the lid is attached to the container body, the inner cover may be displaced in an inclined posture in the longitudinal direction, but the sealed container of the present invention prevents this. Therefore, a stable and strong seal can be obtained at all times in the sealing operation of lying down the lever. Accordingly, the rubber seal does not come into contact with each other and lasts longer. Also, the sealed container is easy to use at home.
