Lid unit and container

Abstract

To provide a lid unit and a container allowing easy and sure opening operation of a lid, while carrying the container with one hand.SOLUTION: In a container 100, a lid 22 has a grip part 22b as an integrated part in a lid unit 2, therefore, strength of the grip part is improved, compared with a structure of connecting both parts where the lid 22 and the grip part 22b are connected as separate parts. In the lid unit 2, since the grip part 22b is formed in the vicinity of a hinge part 21h, by applying a load to the hinge part 21h, the load to other parts can be reduced. Accordingly, the opening operation of the lid 22 while carrying the container 100 safely with one hand can be easily and surely performed, by rotating the lid 22 with the fingers hooked to the grip part 22b via the hinge part 21h.SELECTED DRAWING: Figure 4

Description

[Technical field]

[0001] The present invention relates to a technology regarding a cap unit (lid body) and a container. [Background technology]

[0002] In the past, "a cap unit that can be detachably attached to the mouth and neck of a container body with an open top, a cap body that closes an upper opening of the container body and has a liquid passage hole at an upper portion; a lid body that is rotatably attached to the cap body via a hinge portion and opens and closes the liquid passage port; a lid lock mechanism located on the opposite side of the cap body from the hinge portion and configured to fix the lid body to the cap body, A cap unit characterized in that a finger hook is provided below the hinge portion (see, for example, JP 2018-008715 A) has been proposed. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2018-008715 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the case of a bottle (container) in which the lid (cap body) is opened and closed around a hinge shaft as in the above-mentioned conventional technology, a handle that allows the user to hook their fingers onto the openable lid (cap body) and carry the bottle (container) is not provided. The reason for this is that if a handle is provided on the openable lid (cap body), lifting the handle applies force to the part that locks the lid, and this force may cause the lid to open (the lid may open when the user does not intend), which is undesirable.

[0005] For this reason, when lifting and carrying a bottle (container) whose lid opens and closes around a conventional hinge shaft, the user needs to lift and move the bottle (container) body. In other words, when lifting and carrying a conventional bottle, the user needs to grip the bottle body, so one hand is occupied while carrying the bottle, and as a result, it is difficult to open the lid while carrying the bottle with one hand.

[0006] In view of the above problems, the present invention aims to provide a lid unit and a container that allow the user to easily and reliably open the lid (lid body) while carrying the bottle (container) with one hand. [Means for solving the problem]

[0007] The first invention is A lid unit that is detachably attached to a container body having an open top, The lid body and a lid that is rotatably attached to the lid body via a hinge portion; Equipped with The lid is formed with a handle portion near the hinge portion, on which a finger can be hooked. It is a lid unit.

[0008] In this lid unit, the lid has the handle portion as an integral part, which improves the strength of the handle portion and reduces the number of parts compared to a configuration in which the lid and handle portion are separate parts and connected together.

[0009] In addition, since the handle of this lid unit is formed near the hinge, the load is applied to the hinge and the load on other parts is reduced. Therefore, while safely carrying a container using this lid unit with one hand (with fingers hooked on the handle), the operation of opening the lid body can be easily and reliably performed by rotating the lid via the hinge with the fingers hooked on the handle.

[0010] The second invention is the first invention, The lid body includes a locking portion, The lid is a lock lever that engages with the locking portion to realize a locked state in which the lid is kept closed; A slider for moving the lock lever; a lock release lever for moving the slider; Equipped with The lock release lever is disposed at a position opposite to the handle portion.

[0011] As a result, when transporting a container with this lid unit attached, the container can be moved by hooking a finger on the handle, and when opening the lid of the lid unit, the finger hooked on the handle can be used to press the unlock lever, allowing the lid to be easily opened.

[0012] The third invention is the second invention, The locking portion is disposed at a position spaced a predetermined distance or more from the hinge portion. This allows the lid unit to prevent the locking part from being subjected to a large load even when a large load is applied to the handle part near the hinge part. As a result, even when a large load is applied to the handle part near the hinge part, the locking part and the lock lever are released from their locked state, and the lid unit can be appropriately prevented from opening unintentionally by the user.

[0013] It should be noted that the "predetermined distance" is, for example, a distance longer than the radius of the cylindrical shape when the lid of the lid unit is cylindrical.

[0014] A fourth aspect of the present invention is the second or third aspect of the present invention, The lid is formed with an opening for a re-locking prevention mechanism, The slider is The slider is disposed between the locking portion and the lock release lever, and is installed in a position that allows a portion of the slider to protrude from the opening for the re-lock prevention mechanism when the locked state between the locking portion and the lock lever is released.

[0015] As a result, in this lid unit, when the locked state is released (unlocked state), a part of the slider protrudes from the opening for the re-lock prevention mechanism, and even if the lid is rotated in the opposite direction to when it is opened, the lock lever is prevented from engaging with the engagement portion again, thereby appropriately preventing the lid from being locked (re-locked) unintentionally by the user.

[0016] A fifth aspect of the present invention is a lid unit according to any one of the first to fourth aspects of the present invention; A container body to which the lid unit is detachably attached; A container comprising:

[0017] This makes it possible to realize a container that exhibits the same effects as any one of the first to fourth aspects of the present invention. Effect of the Invention

[0018] An object of the present invention is to provide a lid unit and a container that allow the user to easily and reliably open the lid body while carrying the bottle (container) with one hand. [Brief description of the drawings]

[0037] Assume that the x-axis, y-axis, and z-axis are set as shown in Figs. 1 to 18. The positive x-axis direction is called the front (or forward, forward direction), and the negative x-axis direction is called the rear (or rear, rear direction). The positive z-axis direction is called the up (or upward, upward direction), and the negative z-axis direction is called the down (or downward, downward direction). The positive y-axis direction is called the front (or forward direction), and the negative y-axis direction is called the back (or back direction).

[0038] <1.1: Container composition> 1 to 4, the container 100 includes a container body 1, a lid unit 2 detachably attached to the container body 1, and a straw unit 3 detachably attached to the lid unit 2. The container 100 is a container that can be filled with drinking water and carried, and also allows a user to open the lid portion of the lid unit 2 to drink the drinking water inside the container 100.

[0039] (1.1.1: Container body) The container body 1 has a bottomed tubular shape (for example, a vertically elongated cylindrical shape as shown in Figs. 1 to 4) and has an opening at the top when it is upright. The container body 1 preferably has a vacuum insulation structure in which a metal plate such as stainless steel is formed into a vacuum double structure. The opening of the container body 1 is airtightly sealed with the lid unit 2, thereby making it possible to seal the internal space of the container body 1.

[0040] (1.1.2: Lid unit) The lid unit 2 comprises a lid body 21, a lid 22, a straw attachment unit 23, a first seal member 24, and a second seal member 25.

[0041] The lid body 21 is a member that can be attached to and detached from the container body 1, as shown in, for example, Figs. 1 to 7, and has a substantially cylindrical shape. The lid body 21 is a member that houses the straw attachment unit 23, and is detachably attached to the container body 1 in a state in which the straw attachment unit 23 is housed therein. The lid body 21 also has a hinge portion 21h for rotatably attaching the lid 22, and is connected to the lid 22 via the hinge portion 21h. Note that the hinge portion 21h is preferably made of a material with high strength (for example, metal) since a large load is applied to the hinge portion 21h when the container 100 is lifted by hooking fingers on the handle portion 22b.

[0042] 1 to 10, the lid 22 has an exterior part 22a, a handle part 22b, a base part 22c, an interior part 22d, and a hinge part 22h, and is a member that houses the straw unit 3 inside the lid 22 (inside the interior part 22d). The lid 22 also includes a lock release lever 22RL, a slider 22S, and a lock lever 22LL. The lid 22 is rotatably attached to the lid body 21 via the hinge part 22h provided on the rear end side of the lid 22.

[0043] The exterior part 22a has a hollow structure to accommodate the base part 22c and the interior part 22d. As shown in FIG. 1, FIG. 2, and FIG. 8, the exterior part 22a has a bottom part 22a1 having a substantially circular shape in a plan view, a body part extending upward from the bottom part while decreasing in diameter, and a substantially circular upper part 22a3 having a reduced diameter at the upper end of the body part. The bottom part, body part, and upper part of the exterior part 22a are formed so that the center position of the upper part of the exterior part 22a is forward (positive direction of the x-axis) with respect to the center position of the bottom part of the exterior part 22a in a plan view. In addition, an opening part 22a_hole for mounting the second seal member 25 is formed in the substantially central part of the upper part 22a3 of the exterior part 22a, as shown in FIG. 8. In addition, an opening part 22a2_hole for accommodating the lock release lever 22RL is formed on the rear side (negative direction of the x-axis) of the body part 22a2 of the exterior part 22a, as shown in FIG. 9.

[0044] As shown in Figs. 1 to 5, 8 and 9, the handle portion 22b has a ring shape (when viewed from the side (y-axis direction)), and is formed so as to extend rearward from the rear end of the exterior portion 22a. Specifically, one end of the handle portion 22b is connected to the vicinity of the upper part of the body portion 22a2 of the exterior portion 22a, and the other end is connected to the vicinity of the lower part of the body portion 22a2 of the exterior portion 22a. As shown in Figs. 4 and 5, the handle portion 22b is formed so as to extend outward in a substantially arc shape (a shape of a part of a substantially arc) from the vicinity of the upper part and the vicinity of the lower part of the body portion 22a2 of the exterior portion 22a in a cross-sectional view. The handle portion 22b is also connected to the hinge portion 22h. As a result, the handle portion 22b can rotate around the axis ax_r_h, which is the rotation axis of the hinge portion 22h and the hinge portion 21h, via the hinge portion 22h. In addition, the handle portion 22b is provided at a position facing the unlocking lever 22RL as shown in Figs. 4, 5, and 8. As a result, for example, after a user hooks a finger on the handle portion 22b to lift the container 100, the user can easily perform an operation to put the lid unit 2 into an unlocked state by pressing down the unlocking lever 22RL with a finger in the handle portion 22b. Furthermore, after putting the lid unit 2 into an unlocked state, the user can easily rotate the lid 22 of the lid unit 2 around the rotation axis ax_r_h of the hinge portion 22h and the hinge portion 21h. That is, by performing such an operation, the lid 22 can be easily opened (put into an open state) using only the fingers hooked on the handle portion 22b.

[0045] Handle portion 22b is configured so that its finger hook (the portion on which a finger is hooked (the portion of handle portion 22b facing lock release lever 22RL)) is located near the upper side of hinge portion 22h (hinge axis). By configuring handle portion 22b in this manner, when a finger is hooked on handle portion 22b to lift container 100, a large load can be applied to hinge portion 22h having high strength (e.g., hinge portion 22h made of metal), and the load applied to other portions (in particular, the load applied to the portion where lock lever 22LL is engaged with first locking portion 231a and second locking portion 231b to maintain the locked state) can be reduced.

[0046] The base portion 22c is disposed inside the exterior portion 22a, and its bottom is substantially circular in a plan view, with its radius being substantially the same as the inner diameter of the bottom portion 22a1 of the exterior portion 22a. The base portion 22c is connected (fixed) to the bottom portion 22a1 of the exterior portion 22a, so that the base portion 22c rotates together with the exterior portion 22a around the rotation axis ax_r_h of the hinge portion 22h and the hinge portion 21h.

[0047] As shown in FIG. 7, the base portion 22c is formed with two openings 22c_hole_a and 22c_hole_a for allowing the lower end portion of the slider 22S to protrude.

[0048] 5, the base portion 22c has a hinge portion 22ch for setting the rotation axis of the lock release lever 22RL, and the lock lever 22LL is rotatably connected to the hinge portion 22ch so that the rotation axis becomes the axis ax_22RL. In other words, the lock release lever 22RL is installed on the base portion 22c so as to be rotatable around the axis ax_22RL.

[0049] 5 and 10, a slider 22S is provided on the base portion 22c so as to be slidable up and down (z-axis direction) (the direction of the arrow Dir22S in FIG. 10). A lock lever 22LL is provided on the base portion 22c so as to be slidable back and forth (x-axis direction) (the direction of the arrow Dir22LL in FIG. 10).

[0050] In addition, as shown in FIG. 11, the base portion 22c is provided with elastic body fixing portions 22c_st_a and 22c_st_b for fixing one end of an elastic member (e.g., a spring) for biasing the lock lever 22LL forward (x-axis positive direction).

[0051] The interior portion 22d is formed in a shape that fits along the inner wall of the exterior portion 22a, and is a member that ensures a space inside the interior portion 22d to accommodate the upper straw 32 attached to the straw attachment unit 23. As shown in Fig. 10, the interior portion 22d has an opening 22d_hole at the top for accommodating the second seal member 25. As shown in Fig. 10, the interior portion 22d also has a slider holding portion 22ds that holds the slider 22S in a state in which the slider 22S is slidable (movable) up and down.

[0052] The hinge portion 22h extends rearward from the base portion 22c. As shown in Fig. 10, the hinge portion 22h is connected to the hinge portion 21h of the lid main body 21 so that the lid 22 is rotatable relative to the lid main body 21 (rotatable about the axis ax_r_h as the rotation axis). Since a large load is applied to the hinge portion 22h when the container 100 is lifted by hooking fingers on the handle portion 22b, the hinge portion 22h is preferably made of a material with high strength (for example, metal).

[0053] The unlock lever 22RL is a lever (unlock lever) for releasing the lid 22 from a state in which it is locked to the lid body 21, and for enabling the lid 22 to be opened and closed. The unlock lever 22RL is connected to the base part 22c via a hinge part 22ch of the base part 22c so as to be rotatable about an axis ax_22RL as a rotation axis, as shown in Fig. 5 and Fig. 10, for example. In addition, an end part of the unlock lever 22RL abuts against the upper surface of the slider 22S, and when the user presses down the unlock lever 22RL, a downward force is applied to the upper surface of the slider 22S, thereby causing the slider to slide downward.

[0054] As shown in Figures 5 and 13, the slider 22S has a slide section 23S1, a first leg section 22S2_a extending from the slide section 23S1, and a second leg section 22S2_b extending from the slide section 23S1 in the opposite direction to the first leg section 22S2_a. As shown in Figures 5 and 13, the slider 22S has an approximately flat upper end section, which abuts against an end section of the unlocking lever 22RL. When the user presses down the unlocking lever 22RL, a force from the end section of the unlocking lever 22RL is applied to the upper surface of the slider 22S, causing the slider 22S to slide downward.

[0055] As shown in FIGS. 5 and 13, the slide portion 23S1 is formed so that the rear side thereof is inclined, and the inclined surface is disposed so as to come into contact with the lock lever 22LL.

[0056] As shown in FIG. 13, the first leg portion 22S2_a extends from the slide portion 23S1, and its lower end is shaped to protrude downward (outward) from the opening 22c_hole_a (see FIG. 7) of the base portion 22c when the slider 22S moves (slides) downward.

[0057] As shown in FIG. 13, the second leg portion 22S2_b extends from the slide portion 23S1, and its lower end portion has a shape that protrudes downward (outward) from the opening 22c_hole_b (see FIG. 7) of the base portion 22c when the slider 22S moves (slides) downward.

[0058] In addition, when a force is applied from the end of the unlocking lever 22RL to the upper surface of the slider 22S, and the slider 22S slides downward, the first leg 22S2_a and the second leg 22S2_b protrude from the openings 22c_hole_a, 22c_hole_b (see Figure 7) of the base portion 22c, thereby realizing a re-lock prevention function (details will be described later).

[0059] The lock lever 22LL has a slider abutment portion 22LL1, a first extension portion 22LL2_a, a second extension portion 22LL2_b, a first elastic member engagement portion 22LL3_a, a second elastic member engagement portion 22LL3_b, a first claw portion 22LL4_a, and a second claw portion 22LL4_b, as shown in, for example, Figures 5 and 10 to 13.

[0060] The slider abutment portion 22LL1 is formed to form a slope that abuts against the rear slope of the sliding portion 23S1 of the slider 22S. That is, the slider abutment portion 22LL1 has a shape of a substantially right-angled triangle in a cross-sectional view (see FIGS. 5 and 13). Therefore, when the sliding portion 23S1 of the slider 22S moves (slides) downward, a force is applied from the slope of the sliding portion 23S1 to the slope of the slider abutment portion 22LL1, and as a result, the slider abutment portion 22LL1 moves backward (x-axis negative direction).

[0061] 11 and 12, the first extension portion 22LL2_a has a shape extending so as to surround the outer wall portion of the interior portion 22d in a plan view, and is connected to the slider abutment portion 22LL1, the first elastic member engagement portion 22LL3_a, and the first claw portion 22LL4_a. Note that, as shown in FIG. 13, the first extension portion 22LL2_a is connected to the first claw portion 22LL4_a on the underside of the end portion opposite to the end portion connected to the slider abutment portion 22LL1.

[0062] 11 and 12, the second extension portion 22LL2_b has a shape extended so as to surround the outer wall portion of the interior portion 22d in a plan view, and is connected to the slider abutment portion 22LL1, the second elastic member engagement portion 22LL3_b, and the second claw portion 22LL4_b. Note that, as shown in FIG. 13, the second extension portion 22LL2_b is connected to the second claw portion 22LL4_b on the underside of the end portion opposite to the end portion connected to the slider abutment portion 22LL1.

[0063] 11, the first elastic member engagement portion 22LL3_a is disposed at a position facing the elastic body fixing portion 22c_st_a of the base portion 22c. The first elastic member engagement portion 22LL3_a is biased forward (x-axis positive direction) by an elastic member (e.g., a spring) disposed between the first elastic member engagement portion 22LL3_a and the elastic body fixing portion 22c_st_a.

[0064] 11, the second elastic member engagement portion 22LL3_b is disposed at a position facing the elastic body fixing portion 22c_st_b of the base portion 22c. The second elastic member engagement portion 22LL3_b is biased forward (x-axis positive direction) by an elastic member (for example, a spring) disposed between the second elastic member engagement portion 22LL3_b and the elastic body fixing portion 22c_st_b.

[0065] As shown in Fig. 12 and Fig. 13, the first claw portion 22LL4_a is connected to the lower surface of the end portion of the first extension portion 22LL2_a and is formed to extend forward (x-axis positive direction). When the lid 22 is in a closed state, the first claw portion 22LL4_a is biased forward (x-axis positive direction) together with the first elastic member engagement portion 22LL3_a and the first extension portion 22LL2_a by an elastic member (e.g., a spring) installed between the first elastic member engagement portion 22LL3_a and the elastic body fixing portion 22c_st_a, and the tip of the first claw portion 22LL4_a is engaged with the first engagement portion 231a of the straw attachment unit 23 (see Fig. 14). This brings the lid 22 into close contact with the lid main body 21, and the lid 22 can be maintained in a closed state.

[0066] As shown in Fig. 12 and Fig. 13, the second claw portion 22LL4_b is connected to the lower surface of the end portion of the second extension portion 22LL2_b and is formed to extend forward (x-axis positive direction). When the lid 22 is in a closed state, the second claw portion 22LL4_b is biased forward (x-axis positive direction) together with the second elastic member engagement portion 22LL3_b and the second extension portion 22LL2_b by an elastic member (e.g., a spring) installed between the second elastic member engagement portion 22LL3_b and the elastic body fixing portion 22c_st_b, and the tip of the second claw portion 22LL4_b is engaged with the second engagement portion 231b of the straw attachment unit 23. This brings the lid 22 into close contact with the lid main body 21, and the lid 22 can be maintained in a closed state.

[0067] The straw attachment unit 23 is a member for attaching the straw unit 3. The straw attachment unit 23 is a member attached to the lid body 21, and as shown in FIG. 15, a first locking portion 231a and a second locking portion 231b are provided on the upper surface. The first locking portion 231a and the second locking portion 231b are provided at a position away from the hinge portion 22h of the lid 22. As shown in FIG. 7, the first locking portion 231a and the second locking portion 231b are provided near the periphery on the opposite side to the position where the hinge portion 22h of the lid 22 is provided, and the distance between the first locking portion 231a (or the second locking portion 231b) and the hinge portion 22h is longer than the inner diameter of the lid body 21. As a result, when the handle portion 22b located near the hinge portion 21h is lifted upward while the lid 22 is closed, the force acting on the first locking portion 231a and the second locking portion 231b is small, so that the engagement between the lock lever 22LL and the first locking portion 231a and the second locking portion 231b is released, appropriately preventing the lid 22 from opening unintentionally by the user.

[0068] In addition, as shown in FIG. 15, the straw attachment unit 23 is provided with an opening 23_hole1 for attaching (positioning) the lower seal member 33 of the straw unit 3, and an opening 23_hole2 for attaching (positioning) the upper seal member 34 of the straw unit 3 and ensuring an air hole.

[0069] The first sealing member 24 is a member for sealing the opening at the top of the container body 1. The first sealing member 24 is attached to the bottom of the straw attachment unit 23, and further, when the straw attachment unit 23 to which the first sealing member 24 is attached is attached to the lid body 21, it seals the opening at the top of the container body 1.

[0070] The second seal member 25 is a member for sealing the upper end of the upper straw 32 of the straw unit 3. As shown in Fig. 5, the second seal member 25 is disposed in the opening 22a_hole of the exterior part 22a of the lid 22 and the opening 22d_hole of the interior part 22d, and seals the upper end of the upper straw 32 when the lid 22 is closed. This makes it possible to prevent drinking water or the like contained in the container body 1 from leaking to the outside through the straw unit 3 when the lid 22 is closed.

[0071] (1.1.3: Straw unit) The straw unit 3 is a member for sucking up drinking water or the like contained in the container body 1, and comprises a lower straw 31, an upper straw 32, a straw joint portion 3_JT, a lower sealing member 33, and an upper sealing member 34.

[0072] As shown in Figs. 3 and 16, the lower straw 31 is a substantially cylindrical member, and the upper end portion thereof is attached (connected) to the straw joint portion 3_JT.

[0073] As shown in Figs. 3 and 16, the upper straw 32 is a substantially cylindrical member, and its lower end is attached (connected) to the straw joint portion 3_JT.

[0074] The straw joint part 3_JT is a member for connecting the lower straw 31 and the upper straw, and its inner wall part is formed in a substantially cylindrical shape. Furthermore, the straw joint part 3_JT has a lower seal member 33 attached to its lower part and an upper seal member 34 attached to its upper part.

[0075] The lower seal member 33 is a member for sealing the upper opening (the opening area near where the lower straw is placed) of the container body 1 when the straw unit 3 is attached to the lid body 21. The lower seal member 33 is attached to the lower part of the straw joint part 3_JT as shown in FIG.

[0076] The upper seal member 34 is a member for sealing the vicinity of the outer peripheral edge of the upper straw when the straw unit 3 is attached to the lid body 21. Furthermore, the upper seal member 34 has an air hole seal portion 34a, as shown in the right diagram of FIG. 16. The air hole seal portion 34a has a substantially cylindrical shape, and when the lid 22 is open, it penetrates the inside of the container body 1, and secures a path (path of arrow Dir1 in FIG. 6) for air to enter the inside of the container body 1 from the outside (see FIG. 6). When the lid 22 is closed, the upper portion of the air hole seal portion 34a is in close contact with the lower surface of the base portion 22c of the lid 22, thereby sealing the air hole.

[0077] The straw unit 3 is attached to the straw attachment unit 23 by attaching the straw portion to the opening 23_hole1 of the straw attachment unit 23 and attaching the air hole seal portion 34a of the upper seal member 34 to the opening 23_hole2 of the straw attachment unit 23.

[0078] <1.2: Opening and closing operation of lid unit 2> The opening and closing operations of the lid unit 2 configured as above will now be described.

[0079] Fig. 17 is a diagram for explaining the operation of opening the lid unit 2. Specifically, Fig. 17 is an enlarged perspective view of the lid unit 2 portion of the container 100 according to the first embodiment, in which the force applied when the lid unit 2 is opened is clearly shown in the perspective view excluding the exterior part 22a and the handle part 22b.

[0080] Fig. 18 is a diagram for explaining the operation of opening the lid unit 2. Specifically, Fig. 18 is an enlarged perspective view of the lid unit 2 portion of the container 100 according to the first embodiment, and in the diagram showing the unlock lever 22RL, the slider 22S, the lock lever 22LL, etc., the force applied when the operation of opening the lid unit 2 is performed is clearly indicated.

[0081] Fig. 19 is a diagram for explaining the operation of opening the lid unit 2. Specifically, Fig. 19 is a diagram that shows a schematic side view of the cross-sectional perspective view of Fig. 14, and shows the lock lever 22LL, the first locking portion 231a, the elastic member sprug_a, the elastic body fixing portion 22c_st_a, the straw attachment unit 23, the base portion 22c of the lid 22, and the rotation axis ax_r_h of the hinge portion 22h.

[0082] Fig. 20 is a diagram for explaining the operation of closing the lid unit 2. Specifically, Fig. 20 is a diagram that shows a schematic side view of the cross-sectional perspective view of Fig. 14, and shows the lock lever 22LL, the first locking portion 231a, the elastic member sprug_a, the elastic body fixing portion 22c_st_a, the straw attachment unit 23, the base portion 22c of the lid 22, and the rotation axis ax_r_h of the hinge portion 22h.

[0083] (1.2.1: Operation to open the lid unit 2) First, the operation of opening the lid unit 2 (the operation of opening the lid 22) will be described.

[0084] A case will be described where a user lifts the container 100 with the lid 22 closed by hooking his / her fingers on the handle 22b, and then presses the lock lever 22LL to open the lid 22.

[0085] When the lid 22 is closed, as shown in Fig. 10 and Fig. 11, the lock lever 22LL is biased forward (x-axis positive direction) by the elastic members sprg_a and sprg_b (see Fig. 11). As a result, the first claw portion 22LL4_a of the lock lever 22LL is engaged with the first locking portion 231a of the straw attachment unit 23, and the second claw portion 22LL4_b of the lock lever 22LL is engaged with the second locking portion 231b of the straw attachment unit 23, so that the lid 22 is maintained in a closed state. At this time, when the locking state between the first claw portion 22LL4_a and the first locking portion 231a and the locking state between the second claw portion 22LL4_b and the second locking portion 231b are released, the locked state of the lid 22 is released, and the lid 22 opens. However, since the position where the first claw portion 22LL4_a and the first locking portion 231a are locked and the position where the second claw portion 22LL4_b and the second locking portion 231b are locked are located away from the hinge portion 22h (see Figs. 12 and 14), even if the handle portion 22b (see Fig. 5) above the hinge portion 22h is lifted upward with a finger, the force applied to the locking position is small, and as a result, the locked state of the lid 22 (the state where the lid 22 is closed) can be reliably (safely) maintained. In other words, it is possible to appropriately prevent the locked state of the lid 22 from being released unintentionally by the user and the lid 22 from opening inadvertently. In other words, the user can hook his / her fingers on the handle portion 22b and lift the container 100 with the lid 22 closed, and transport the container 100 safely (without the lid 22 opening unintentionally during the process).

[0086] When the user wishes to open the lid 22 of the container 100, the user presses down the lock release lever 22RL. That is, the user applies force in the direction of the arrow shown in Figure 8 (1) to press down the lock release lever 22RL.

[0087] When a force is applied in the direction of the arrow shown in (1) of Figure 8 and (1) of Figure 17, the lock release lever 22RL rotates downward about the axis ax_22RL, and a downward force is applied to the upper surface of the slider 22S from the end of the lock release lever 22RL that is in contact with the upper surface of the slider 22S (the force is applied in the direction of the arrow shown in (2) of Figure 17 and Figure 18). This causes the slider 22S to slide downward.

[0088] As shown in FIG. 17, the slider 22S is restricted by the slider holding portion 22ds to only move in the vertical direction, and the rear side of the slide portion 23S1 of the slider 22S is formed so as to form a slope. Therefore, when the slider 22S moves (slides) downward, a force is generated in which the slider 22S presses the interior portion 22d (the force indicated by the arrow in (3A) of FIG. 17), and when the slider 22S presses the slider abutment portion 22LL1 of the lock lever 22LL downward via the slope on the rear side of the slide portion 23S1 of the slider 22S, a force is generated that moves the lock lever 22LL backward (negative direction of the x-axis) (the force indicated by the arrow in (3B) of FIG. 17, FIG. 18, and FIG. 19).

[0089] When a force (the force of the arrow shown in (3B) of FIG. 17, FIG. 18, and FIG. 19) that moves the lock lever 22LL backward (x-axis negative direction) is generated, the lock lever 22LL moves backward (x-axis negative direction) and reaches the state shown in state 2 of FIG. 19, the engagement between the first claw portion 22LL4_a of the lock lever 22LL and the first locking portion 231a and the engagement between the second claw portion 22LL4_b of the lock lever 22LL and the second locking portion 231b are released (the locked state is released). When the locked state of the lock lever is released in this way, the lid 22 (the base portion 22c of the lid 22, the lock lever 22LL, etc.) rotates in the direction shown by rot1 in the middle diagram of FIG. 19 around the rotation axis x_r_h of the hinge portion 22h as the center of rotation. That is, the action of kicking up the lid 22 is achieved (the lid 22 rotates in the direction of the arrow shown in FIG. 17(4)).

[0090] Then, the state transitions from state 2 to state 3 in FIG. 19. That is, the lid 22 (base portion 22c of the lid 22, lock lever 22LL, etc.) rotates in the direction indicated by rot1 in the middle diagram of FIG. 19 around the rotation axis x_r_h of the hinge portion 22h as the center of rotation, and the lock lever 22LL is pushed forward by the elastic force (force (repulsion force) in the direction indicated by F1 in FIG. 19) of the elastic member sprg_a (and elastic member sprg_b), resulting in state 3 in FIG. 19, and the lid 22 is in an unlocked state. Also, in this state, as shown in state 3 in FIG. 19, a part of the first leg portion 22S2_a (and the second leg portion 22S2_b) of the slider 22S protrudes from the opening 22c_hole_a (and 22c_hole_b) (see FIG. 7) of the base portion 22c. This results in a re-lock prevention state. That is, a part of the first leg 22S2_a (and the second leg 22S2_b) of the slider 22S protrudes from the opening 22c_hole_a (and 22c_hole_b) (see FIG. 7) of the base portion 22c, so in order for the user to close the lid 22, it is necessary to push the lid 22 downward in FIG. 19 with a certain amount of force or more (a force that returns the lock lever 22LL to the locked state and moves the slider 22S upward to a state where there is no protruding portion). This makes it possible to appropriately prevent the lid 22 from being unintentionally locked again.

[0091] In state 3, the lid 22 is in an unlocked state, and therefore, when the user moves (applies force to) the fingers hooked on the handle portion 22b along the inner circumference (arc) of the handle portion 22b, the lid 22 rotates about the rotation axis ax_r_h of the hinge portion 22h as the center of rotation, and the lid 22 can be opened. That is, by performing such an operation, the lid 22 can be opened as shown in FIG.

[0092] (1.2.2: Closing operation of lid unit 2) Next, a description will be given of the operation of closing the lid unit 2 (the operation of closing the lid 22). The operation of closing the lid unit 2 (the operation of closing the lid 22) is the reverse operation of the operation of opening the lid unit 2 (the operation of opening the lid 22).

[0093] When the lid 22 is in the open state, the user hooks their fingers on the handle portion 22b and moves (applies force to) it along the inner circumference (arc) of the handle portion 22b, thereby rotating the lid 22 around the rotation axis ax_r_h of the hinge portion 22h as the rotation center, thereby bringing the lid 22 into state 4 in Figure 20.

[0094] Then, in the state of State 4 in Fig. 20, the user applies force to the lid 22 in the direction indicated by rot2 in the upper diagram of Fig. 20. As a result, the lid 22 rotates further downward around the rotation axis ax_r_h as the center of rotation, and is pressed against the upper surface of the first locking portion 231a, causing the lock lever 22LL to move backward, and the elastic member sprg_a to contract. Then, the lid 22 rotates to a position where the lower surface of the base portion 22c of the lid 22 is approximately parallel to the upper surface of the straw attachment unit 23, resulting in State 5 in Fig. 20.

[0095] In state 5, a forward force (force in the direction indicated by F2 in FIG. 20) is applied to the lock lever 22LL by the elastic force (repulsive force) from the elastic member sprg_a in the contracted state. This causes the lock lever 22LL to move forward, and the first claw portion 22LL4_a of the lock lever 22LL engages with the first engagement portion 231a (state 6 in FIG. 20). In other words, the lock lever 22LL is in a locked state, and the lid 22 is in a locked state. By operating in this manner, the lid unit 2 can be closed (the lid 22 can be closed).

[0096] <Summary> In the container 100, the lid 22 of the lid unit 2 has the handle portion 22b as an integral part (the handle portion 22b can be integrally molded in the lid 22), so that the strength of the handle portion is improved and the number of parts can be reduced compared to a configuration in which the lid and handle portion are separate parts and connected together.

[0097] Furthermore, in the container 100, the lid unit 2 is configured such that the finger hook portion of the handle portion 22b (the portion for hooking the finger (the portion of the handle portion 22b facing the lock release lever 22RL)) is located near the upper portion of the hinge portion 22h (hinge axis). Therefore, the load is applied to the strong hinge portion 22h (e.g., a metal hinge portion 22h) and the load on other portions (particularly the portion where the lock lever 22LL engages with the first locking portion 231a and the second locking portion 231b to maintain the locked state) can be reduced.

[0098] Furthermore, in the container 100, the first locking portion 231a and the second locking portion 231b in the lid unit 2 are disposed at a position away from the hinge portion 22h of the lid 22. As a result, when the lid 22 is closed and the handle portion 22b disposed near the hinge portion 22h is lifted upward, the force acting on the first locking portion 231a and the second locking portion 231b is small, so that the engagement state between the lock lever 22LL and the first locking portion 231a and the second locking portion 231b is released, and the lid 22 can be appropriately prevented from being opened unintentionally by the user (unintentional unlocking by the user can be appropriately prevented).

[0099] In addition, in the container 100, the lid 22 can be opened by pressing down the unlocking lever with a finger hooked on the handle portion 22b in the lid unit 2. That is, the container 100 can be lifted and carried by using a finger hooked on the handle portion 22b (using only the fingers of one hand), and the operation of opening the lid 22 can be easily performed in succession. That is, in the container 100, by pressing down the unlocking lever with a finger hooked on the handle portion 22b in the lid unit 2, the slider 22S moves downward and the lock lever 22LL moves backward, and the lock lever 22LL is released from the locking engagement with the first locking portion 231a and the second locking portion 231b (unlocked). Furthermore, after unlocking, the user can move (apply force to) the fingers hooked on handle portion 22b along the inner circumference (arc) of handle portion 22b, causing lid 22 to rotate around rotation axis ax_r_h of hinge portion 22h as the center of rotation, thereby opening lid 22.

[0100] That is, in the container 100, the operation of unlocking and opening the lid 22 can be performed as a series of movements by using a finger hooked on the handle portion 22b of the lid unit 2.

[0101] Furthermore, in the container 100, the operation of opening the lid 22 in the lid unit 2 is achieved by kicking up the lid 22 with the lock lever 22LL after unlocking, so that the operation of opening the lid 22 can be easily performed by pressing down the lock release lever 22RL with a finger hooked on the handle portion 22b.

[0102] Furthermore, in the container 100, when the lid unit 2 is unlocked, the slider 22S slides downward, and the first leg portion 22S2_a and the second leg portion 22S2_b protrude from the openings 22c_hole_a, 22c_hole_b of the base portion 22c, thereby appropriately preventing the lid 22 from being unintentionally relocked.

[0103] As described above, with container 100, the operation of opening the lid while carrying container 100 with one hand (with fingers hooked on handle portion 22b) can be easily and reliably performed.

[0104] [Other embodiments] In the above embodiment of the container 100, a configuration including a straw unit 3 has been described, but the present invention is not limited to this. For example, instead of the straw unit 3, the container may have a mechanism in which a drinking spout for drinking water or the like contained in the container body 1 is formed in the lid unit 2.

[0105] In the above embodiment, the term "same" is a concept that includes being roughly the same.

[0106] In addition, in the above embodiment, among the components, there are some parts which are simplified and show only the main components necessary for the above embodiment. Therefore, any components not specified in the above embodiment may be included. In addition, in the above embodiment and drawings, the dimensions of each component may not faithfully (strictly) represent the actual dimensions and dimensional ratios. Therefore, the dimensions and dimensional ratios may be changed within the scope of the present invention.

[0107] The specific configuration of the present invention is not limited to the above-described embodiment, and various changes and modifications are possible without departing from the gist of the invention. [Explanation of symbols]
