Description

The present invention relates to technology for a straw unit (straw attachment mechanism) that can be attached to and detached from a container.

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 portion is provided below the hinge portion (see, for example, JP 2018-008715 A)."
"The liquid passage port is made of a flexible straw,
A cap unit has been proposed (see, for example, JP 2018-008715 A) in which the straw is arranged to protrude from the upper part of the cap body and is stored in a folded state inside the lid body when the lid body is fixed to the cap body by the lid locking mechanism.

JP 2018-008715 A

As in the above-mentioned conventional technology, if a flexible straw is provided protruding from the top of the cap body and is stored in a folded state inside the lid when the lid is fixed to the cap body by the lid locking mechanism, the elastic force (restoring force) of the folded straw is applied to the lid when the lid is closed. When a user opens the lid in this state, the lid opens with more force than the user expects, making it difficult for the user to use.

In addition, flexible straws are often made of rubber, and there is a problem that users who are uncomfortable drinking from a straw made of rubber by putting their mouth on it will not want to use a straw made of rubber.

In view of the above problems, the present invention aims to provide a container with a lid that is easy to use and allows the user to open the lid safely and reliably without the lid opening too forcefully when opening it, and a straw unit (straw attachment mechanism) for use with the container.

The first invention is
A straw unit for attaching a straw to a lid unit that is detachably attached to a container body having an open top,
A first straw;
A second straw;
A straw joint portion for connecting the first straw and the second straw;
Equipped with
The straw joint portion has a configuration for fixing one end of the first straw and one end of the second straw.
It is a straw unit.

This allows a straw unit to be constructed by connecting the first straw and the second straw, which are separate straws, to the straw joint portion.
The second invention is the first invention,
An upper seal member installed to cover one end of the straw joint portion;
A lower seal member installed to cover the other end of the straw joint portion;
It further comprises:

This makes it possible to realize a straw joint part that includes an upper seal member and a lower seal member. For example, by attaching the straw joint part that includes an upper seal member and a lower seal member to a predetermined location on the lid unit, the positioning of the straw joint part and the first straw and/or the second straw attached to the straw joint part can be performed reliably and accurately.

The third invention is the second invention,
The upper seal member is
The container has a seal portion that prevents leakage from the first straw, and an air hole seal portion that ensures an air hole that communicates with the inside of the container body and seals the air hole when the lid unit is closed.

This makes it possible to create an upper seal member that has an integrated air hole seal portion, reducing the number of parts.

The fourth invention is
A straw unit according to any one of the first to third aspects of the present invention;
A lid body having a lid that can be opened and closed freely, the lid body to which the straw unit can be attached;
A lid seal member attached to the lid body;
Equipped with
The lid seal member is disposed at a position where it seals one end of the first straw of the straw unit when the lid of the lid body is closed.
It is a lid unit.

In this lid unit, the straw joint of the straw unit is attached to a predetermined position on the lid body, so that the positions (upper and lower positions) of the first straw and the second straw can be reliably positioned. This fixes the position of the straw (particularly the position of the upper end of the first straw), so that when the lid is closed, a reliable seal can be made between the end face (upper end face) of the first straw and the lid seal member provided on the lid.

In addition, when the lid unit is opened from a closed state, the lid seal member simply separates from the first straw of the straw unit, so the first straw does not deform. As a result, with this lid unit, the user can open the lid safely and reliably without the lid opening too forcefully.

The fifth invention is
A lid unit according to a fourth aspect of the present invention;
A container body to which the lid unit is detachably attached;
A container comprising:

This makes it possible to realize a container that has the same effect as the fourth invention.

The present invention makes it possible to realize a container with a lid that is easy to use and allows the user to open the lid safely and securely without the lid opening too forcefully when opening it, and a straw unit (straw attachment mechanism) for use with the container.

The positive direction of the z-axis is called the top (or upward, upward direction), and the negative direction of the z-axis is called the bottom (or downward, downward direction). The positive direction of the y-axis is called the front (or forward direction), and the negative direction of the y-axis is called the back (or back direction).

<1.1: Configuration of container>
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, for example, and that allows a user to open the lid portion of the lid unit 2 and drink the drinking water inside the container 100 with the straw of the straw unit 3.

(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 container body 1 has an opening that is airtightly sealed with the lid unit 2, thereby making it possible to seal the internal space of the container body 1.

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

As shown in Figs. 1 to 7, for example, the lid body 21 is a member that can be attached to and detached from the container body 1, and has a generally 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 with the straw attachment unit 23 housed in it. 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 high-strength material (e.g., metal) because a large load is applied to the hinge portion 21h when the container 100 is lifted by placing fingers on the handle portion 22b.

As shown in Figures 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 has a lock release lever 22RL, a slider 22S, and a lock lever 22LL. The lid 22 is also rotatably attached to the lid body 21 via the hinge part 22h provided on the rear end side of the lid 22.

The exterior part 22a has a hollow structure to accommodate the base part 22c and the interior part 22d. The exterior part 22a has a bottom part 22a1 that is substantially circular in plan view, a body part that extends upward from the bottom part while reducing in diameter, and a substantially circular upper part 22a3 that is reduced in diameter at the upper end of the body part, as shown in Figs. 1, 2, and 8. 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 plan view. In addition, an opening 22a_hole for attaching 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. As shown in FIG. 9, an opening 22a2_hole for accommodating the unlock lever 22RL is formed on the rear side (x-axis negative direction side) of the body 22a2 of the exterior part 22a.

As shown in Figs. 1 to 5, 8 and 9, for example, the handle portion 22b has a ring shape (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. This allows the handle portion 22b to rotate via the hinge portion 22h about the axis ax_r_h, which is the rotation axis of the hinge portion 22h and the hinge portion 21h. Also, as shown in Figures 4, 5, and 8, the handle portion 22b is provided in a position facing the lock release lever 22RL.

The handle portion 22b is configured so that the finger hook portion (the portion on which the finger is hooked (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).

The base portion 22c is installed 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, together with the exterior portion 22a, rotates around the rotation axis ax_r_h of the hinge portion 22h and the hinge portion 21h.

As shown in FIG. 7, the base portion 22c has two openings 22c_hole_a and 22c_hole_a for allowing the lower end of the slider 22S to protrude.

As shown in FIG. 5, the base portion 22c has a hinge portion 22ch for setting the rotation axis of the unlocking lever 22RL, and the locking lever 22LL is rotatably connected to the hinge portion 22ch so that the rotation axis is the axis ax_22RL. In other words, the unlocking lever 22RL is installed on the base portion 22c so that it can rotate around the axis ax_22RL.

As shown in Figs. 5 and 10, the slider 22S is mounted 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). The lock lever 22LL is mounted 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).

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 (positive direction of the x-axis).

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 secures 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 while the slider 22S is slidable (movable) up and down.

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 body 21 so that the lid 22 can rotate freely relative to the lid body 21 (rotating freely around the axis ax_r_h as the rotation axis). Note that the hinge portion 22h is preferably made of a high-strength material (e.g., metal) because a large load is applied to the hinge portion 22h when the container 100 is lifted by placing fingers on the handle portion 22b.

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

As shown in Figures 5 and 13, for example, 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 a substantially flat upper end section that abuts against the end section of the unlocking lever 22RL. When the user presses down on 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.

As shown in Figures 5 and 13, the slide portion 23S1 is formed so that the rear side is inclined, and the inclined surface is positioned so as to abut against the lock lever 22LL.

As shown in FIG. 13, the first leg 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.

As shown in FIG. 13, the second leg 22S2_b extends from the slide portion 23S1, and its lower end is shaped to protrude downward (outward) from the opening 22c_hole_b (see FIG. 7) of the base portion 22c when the slider 22S moves (slides) downward.

When a force is applied from the end of the unlocking lever 22RL to the top surface of the slider 22S, causing the slider 22S to slide downward, the first leg 22S2_a and the second leg 22S2_b protrude from the openings 22c_hole_a, 22c_hole_b (see FIG. 7) of the base portion 22c, thereby realizing a re-lock prevention function.

As shown in, for example, Figures 5 and 10 to 13, 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.

The slider abutment portion 22LL1 is formed to form a slope that abuts against the rear slope of the slide portion 23S1 of the slider 22S. In other words, the slider abutment portion 22LL1 has a shape of a roughly right-angled triangle in cross section (see Figures 5 and 13). Therefore, when the slide portion 23S1 of the slider 22S moves (slides) downward, a force is applied from the slope of the slide portion 23S1 to the slope of the slider abutment portion 22LL1, which causes the slider abutment portion 22LL1 to move rearward (negative x-axis direction).

As shown in Figs. 11 and 12, the first extension portion 22LL2_a has a shape that extends 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 the end portion connected to the slider abutment portion 22LL1.

As shown in Figs. 11 and 12, the second extension portion 22LL2_b has a shape that extends 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. 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 the end portion connected to the slider abutment portion 22LL1.

As shown in FIG. 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.

As shown in FIG. 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 (e.g., a spring) disposed between the second elastic member engagement portion 22LL3_b and the elastic body fixing portion 22c_st_b.

As shown in Figs. 12 and 13, the first claw portion 22LL4_a is connected to the underside of the end of the first extension portion 22LL2_a and is formed to extend forward (x-axis positive direction). When the lid 22 is closed, 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.

As shown in Figs. 12 and 13, the second claw portion 22LL4_b is connected to the underside of the end of the second extension portion 22LL2_b and is formed to extend forward (x-axis positive direction). When the lid 22 is closed, 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.

The straw attachment unit 23 is a member for attaching the straw unit 3. The straw attachment unit 23 is also a member that is 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.

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 securing an air hole.

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 with the first sealing member 24 attached is attached to the lid body 21, it seals the opening at the top of the container body 1.

The second sealing 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 sealing 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 etc. contained in the container body 1 from leaking to the outside through the straw unit 3 when the lid 22 is closed.

(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.

As shown in Figures 3, 16, and 17, the lower straw 31 is a substantially cylindrical member, and its upper end is attached (connected) to the straw joint part 3_JT. The lower straw 31 is made of a material (e.g., metal (e.g., stainless steel) or resin material) (highly rigid material) that is not easily deformed even when an external force is applied. It is preferable to use highly rigid stainless steel or titanium as the material for the lower straw 31.

As shown in Figs. 3, 16, and 17, the upper straw 32 is a substantially cylindrical member, and its lower end is attached (connected) to the straw joint part 3_JT. The upper straw 32 is made of a material (e.g., metal (e.g., stainless steel) or resin material) (highly rigid material) that is not easily deformed even when an external force is applied. It is preferable to use highly rigid stainless steel or titanium as the material of the upper straw 32. The material of the upper straw 32 may be the same as that of the lower straw, or it may be different. For example, the upper straw 32 may be made of a material (hygienic material) (antibacterial material, Ag alloy, rust-resistant metal, hygienic resin (antibacterial treated resin), etc.) that can maintain a hygienic state even when the user puts it in their mouth.

The straw joint part 3_JT is a member for connecting the lower straw 31 and the upper straw. As shown in Figures 3 and 16 to 19, the straw joint part 3_JT has a substantially cylindrical body part 3_JT_a, a first outer peripheral part 3_JT_b, a second outer peripheral part 3_JT_c, a third outer peripheral part 3_JT_d, and an inner peripheral part 3_JT_e.

As shown in Fig. 18 and Fig. 19, the body 3_JT_a is a member having a substantially cylindrical shape. The body 3_JT_a is formed so that its inner diameter is larger than the outer diameter of the upper end (the end connected to the straw joint part 3_JT) of the lower straw 31 and larger than the outer diameter of the lower end (the end connected to the straw joint part 3_JT) of the upper straw 32 so that the lower straw 31 and the upper straw 32 can be accommodated (inserted). In addition, when the ends of the upper straw 32 and the lower straw are processed to have a convex shape, a part of the inside of the body 3_JT_a (a part of the inner wall part) may be formed with a shape corresponding to the convex shape of the ends of the upper straw 32 and the lower straw (a concave shape corresponding to the convex shape of the ends of the upper straw 32 and the lower straw so that the upper straw 32 and the lower straw can be press-fitted) (see Fig. 20).

As shown in Figs. 18 and 19, the first outer peripheral portion 3_JT_b is formed so as to protrude outwardly from the body portion 3_JT_a at a predetermined height of the body portion 3_JT_a at a substantially uniform distance. In other words, the first outer peripheral portion 3_JT_b is a member having a ring shape that surrounds the outer wall of the body portion 3_JT_a at a predetermined height of the body portion 3_JT_a. In other words, the first outer peripheral portion 3_JT_b is a member having a ring shape (a shape defined by two concentric circles) with the central axis (cylindrical axis) of the body portion 3_JT_a as its center (central axis) when viewed in a plan view from above. In addition, the first outer peripheral portion 3_JT_b is a member (positioning member) for determining the position of the upper seal member 34 when the upper seal member 34 is attached to the straw joint portion 3_JT (see Fig. 20).

As shown in Figs. 18 and 19, the second outer peripheral portion 3_JT_c is formed so as to protrude outwardly from the body portion 3_JT_a at a predetermined height of the body portion 3_JT_a at a substantially uniform distance. In other words, the second outer peripheral portion 3_JT_c is a member having a ring shape that surrounds the outer wall of the body portion 3_JT_a at a predetermined height of the body portion 3_JT_a. In other words, the second outer peripheral portion 3_JT_c is a member having a ring shape (a shape defined by two concentric circles) with the central axis (cylindrical axis) of the body portion 3_JT_a as its center (central axis) in a plan view. In addition, the second outer peripheral portion 3_JT_c is a member (positioning member) for determining the position of the lower seal member 33 when the lower seal member 33 is attached to the straw joint portion 3_JT (see Fig. 20).

As shown in Figs. 18 and 19, the third outer peripheral portion 3_JT_d is formed so as to protrude outwardly from the body portion 3_JT_a at a predetermined height of the body portion 3_JT_a at a substantially uniform distance. In other words, the third outer peripheral portion 3_JT_d is a member having a ring shape that surrounds the outer wall of the body portion 3_JT_a at a predetermined height of the body portion 3_JT_a. In other words, the third outer peripheral portion 3_JT_d is a member having a ring shape (a shape defined by two concentric circles) with the central axis (cylindrical axis) of the body portion 3_JT_a as its center (central axis) in a plan view. In addition, the third outer peripheral portion 3_JT_d is a member for maintaining the lower seal member 33 in intimate contact with the straw joint portion 3_JT when the lower seal member 33 is attached to the straw joint portion 3_JT (see Fig. 20).

The third outer peripheral portion 3_JT_d is formed so that the amount of outward protrusion (protruding length) of the third outer peripheral portion 3_JT_d is smaller than the amount of outward protrusion (protruding length) of the second outer peripheral portion 3_JT_c.

As shown in Figs. 18 and 19, the inner peripheral portion 3_JT_e is formed so as to protrude inward from the body portion 3_JT_a at a predetermined height of the body portion 3_JT_a approximately evenly. In other words, the inner peripheral portion 3_JT_e is a member having a ring shape surrounded by the inner wall of the body portion 3_JT_a at a predetermined height of the body portion 3_JT_a. In other words, the inner peripheral portion 3_JT_e is a member having a ring shape (a shape defined by two concentric circles) with the central axis (cylindrical axis) of the body portion 3_JT_a as the center (central axis) in a plan view. In addition, the inner peripheral portion 3_JT_e is formed so that its inner diameter is smaller than the outer diameter of the upper end portion (the end portion connected to the straw joint portion 3_JT) of the lower straw 31 and smaller than the outer diameter of the lower end portion (the end portion connected to the straw joint portion 3_JT) of the upper straw 32. This allows the lower straw 31 and the upper straw 32 to be positioned so that when the lower straw 31 and the upper straw 32 are attached to the straw joint part 3_JT, the upper end of the lower straw 31 (the end that connects to the straw joint part 3_JT) and the lower end of the upper straw 32 (the end that connects to the straw joint part 3_JT) come into contact with the lower and upper surfaces of the inner peripheral part 3_JT_e, respectively. In other words, this allows the lower straw 31 and the upper straw 32 to be accurately positioned when they are attached to the straw joint part 3_JT (see FIG. 19 (a diagram of the lower straw 31 when attached to the straw joint part 3_JT) and FIG. 20 (a diagram of the lower straw 31 and the upper straw 32 when attached to the straw joint part 3_JT)).

The inner peripheral portion 3_JT_e is disposed in the region between the first outer peripheral portion 3_JT_b and the second outer peripheral portion 3_JT_b, as shown in Figures 18 and 19.

As shown in FIG. 20, the straw joint part 3_JT has a lower straw 31 attached (inserted) to the lower inside part, an upper straw 32 attached (inserted) to the upper inside part, a lower seal member 33 attached to the lower outside part, and an upper seal member 34 attached to the upper outside part.

The lower seal member 33 is a member for sealing the upper opening of the container body 1 (the opening area near where the lower straw is placed) 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 Figures 16 and 17. As shown in Figure 21, the lower seal member 33 is a substantially cylindrical member with a recess formed near the upper part. The lower seal member 33 is attached to the straw joint part 3_JT so that the recess near the upper part abuts against the third outer peripheral part 3_JT_d of the straw joint part 3_JT. This allows the lower seal member 33 to be accurately attached to a predetermined position of the straw joint part 3_JT, as shown in Figure 20.

The upper seal member 34 is a member for sealing the outer peripheral portion of the upper straw when the straw unit 3 is attached to the lid body 21. Furthermore, as shown in Figures 16, 17 (right), 20, and 21, the upper seal member 34 has a straw seal portion 34a, a connection portion 34b, and an air hole seal portion 34c.

As shown in FIG. 22, the straw seal part 34a has a substantially cylindrical shape, and the connection part 34b is connected to a part of the outside of the side wall part. As shown in FIG. 20, the straw seal part 34a is attached to the straw joint part 3_JT so that the lower end part contacts the upper surface of the first outer peripheral part 3_JT_b of the straw joint part 3_JT, and the outer wall part contacts the outer wall part of the body part 3_JT_a of the straw joint part 3_JT. As shown in FIG. 20, the straw seal part 34a has a shape such that when the upper straw 32 is attached to the straw joint part 3_JT, the upper inner wall part contacts the inner wall part of the upper straw 32. As a result, by attaching the straw seal part 34a to the straw joint part 3_JT to which the upper straw 32 is attached, it is possible to prevent leakage of drinking water, etc. from the upper straw 32.

As shown in FIG. 22, the connection part 34b is a member that connects the straw seal part 34a and the air hole seal part 34c. One end of the connection part 34b is connected to the straw seal part 34a, and the other end is connected to the air hole seal part 34c.

As shown in FIG. 22, the air hole seal portion 34c has a flat plate portion 34c1 and an air hole portion 34c2.

The flat plate portion 34c1 is a flat plate-shaped member and is connected to the connection portion 34b. In addition, an air hole portion 34c2 is formed so as to penetrate the flat portion of the flat plate portion 34c1.

As shown in FIG. 22, the air hole portion 34c2 is a substantially cylindrical member and is formed to penetrate the flat portion of the flat portion 34c1. When the upper seal member 34 is attached to the straw attachment unit 23, the air hole portion 34c2 is disposed in the opening 23_hole2 (see FIG. 15) of the straw attachment unit 23, and is a member for securing an air hole with the container body 1 and sealingly (blocking) the air hole when the lid 22 is closed (see FIGS. 5 and 6). When the lid 22 is closed, the upper end of the air hole portion 34c2 comes into close contact with the underside of the base portion 22c of the lid 22, sealingly (blocking) the air hole.

In this way, when the lid 22 is open, the air hole seal portion 34c penetrates the inside of the container body 1, and ensures a path for air to enter the inside of the container body 1 from the outside (path indicated by arrow Dir1 in FIG. 6) (see FIG. 6). When the lid 22 is closed, the upper part of the air hole portion 34c2 of the air hole seal portion 34c is in close contact with the underside of the base portion 22c of the lid 22, thereby sealing the air hole.

The straw unit 3 is attached to the straw attachment unit 23 by attaching the straw seal portion 34a to the opening 23_hole1 of the straw attachment unit 23 and attaching the air hole seal portion 34c of the upper seal member 34 to the opening 23_hole2 of the straw attachment unit 23 (see Figures 15, 23 to 26).

The straw joint part 3_JT, to which the lower seal member 33 and upper seal member 34 are attached, functions as a positioning part, and when the straw unit 3 is attached to the lid body 21, the vertical positions of the straws (the positions of the upper straw 32 and lower straw 31) can be reliably positioned. This fixes the vertical positions of the straws (particularly the position of the upper straw 32), so that when the lid 22 is closed, a reliable seal can be formed between the end surface (top end surface) of the upper straw 32 and the upper seal member 34 provided (attached) on the lid 22.

For example, when the lid 22 is closed in the lid unit 2 in which the straw unit 3 is attached to the straw attachment unit 23, the second seal member 25 attached to the lid 22 seals the upper part of the upper straw 32 as shown in FIG. 5. Then, when the lid 22 is opened from the closed state, that is, when the lid 22 is rotated around the rotation axis ax_r_h of the hinge part 21h, the upper part of the upper straw 32 separates from the second seal member 25, and the sealed state between the upper part of the upper straw 32 and the second seal member 25 is dissolved. At this time (when the lid 22 is opened), the upper straw 32 is made of a highly rigid material and does not deform even when its upper part separates from the second seal member 25. This allows the user to open the lid 22 safely and reliably without the lid 22 opening forcefully.

<Summary>
The container 100 does not have a structure in which the straw is deformed to seal when the lid is closed, as in the conventional technology, so that when the lid 22 is opened from a closed state, the lid 22 does not open forcefully.

In addition, by making the straws into a divided structure, it is possible to process the end faces of each straw (upper straw 32 and lower straw 31) into a convex shape, and this makes it possible to attach (press-fit) each straw (upper straw 32 and lower straw 31) to the straw joint part 3_JT (e.g., straw joint part 3_JT made of a resin material) that connects each straw (upper straw 32 and lower straw 31).

In addition, in the container 100, the straw joint part 3_JT to which the lower seal member 33 and the upper seal member 34 are attached functions as a positioning part, and when the straw unit 3 is attached to the lid body 21, the vertical positions of the straws (the positions of the upper straw 32 and the lower straw 31) can be reliably positioned. This fixes the vertical positions of the straws (particularly the position of the upper straw 32), so that when the lid 22 is closed, a reliable seal can be formed between the end surface (top end surface) of the upper straw 32 and the upper seal member 34 provided (attached) on the lid 22.

In addition, in the container 100, the lower seal member 33 attached to the straw joint portion 3_JT also serves the function of preventing leakage of beverages, etc. from the container body 1 when the straw unit 3 is attached to the straw attachment unit 23.

In addition, in the container 100, the upper seal member 34 attached to the straw joint portion 3_JT is structured to also have a portion for sealing the air vent hole (air hole), which is essential for bottles with straws. This reduces the number of parts compared to providing another separate part (small part) for sealing the air vent hole (air hole), and also prevents parts from being lost during cleaning.

As described above, the present invention makes it possible to realize a container 100 (container with lid) that is easy to use and allows the user to open the lid safely and reliably without the lid opening too forcefully when opening the lid, and a straw unit 3 (straw attachment mechanism) used with the container 100.

[Other embodiments]
In the straw unit 3 of the container 100 of the above embodiment, it is not assumed that the user will disassemble the upper straw 32, the lower straw 31, the straw joint part 3_JT, the upper seal member 34, and the lower seal member 33. However, in the straw unit 3, the upper straw 32, the lower straw 31, the straw joint part 3_JT, the upper seal member 34, and/or the lower seal member 33 may be configured to be disassembled by the user (for example, for maintenance (for example, cleaning, etc.)). In this case, when assembling the upper straw 32, the lower straw 31, the straw joint part 3_JT, the upper seal member 34, and/or the lower seal member 33 after disassembly, a positioning mechanism (for example, a claw part, a protrusion, a recess, etc. provided at a predetermined position) may be provided so that the positions of each component are reliably fixed at a predetermined position. In this way, even if the straw unit 3 is disassembled and then reassembled by the user, each component will be accurately positioned at a predetermined position, and the function of the straw unit 3 can be reliably reproduced.

In the above embodiment, "same" is a concept that includes being roughly the same.

In addition, in the above embodiment, some of the components are shown in a simplified form, with only the main components necessary for the above embodiment. Therefore, any components not explicitly shown 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, dimensional ratios, etc. may be changed without departing from the spirit of the present invention.

The specific configuration of the present invention is not limited to the above embodiment, and various changes and modifications are possible without departing from the gist of the invention.
