Description

Cap unit and capped container

Technical Field

The present invention relates to a lid unit and a capped container.

Background

Conventionally, there is known a cap unit detachably attached to a neck portion of a container body having an upper opening (for example, patent document 1).

The cover unit of patent document 1 includes: a cover body having a liquid passage; a lid body rotatably attached to the lid body via a hinge, wherein the lid body closes the liquid passage opening with the lid filler in a state of being biased in a direction of opening the liquid passage opening (opening direction); and a cover locking mechanism for fixing the cover body relative to the cover body at a closing position where the cover body closes the liquid through hole.

For example, when a hot beverage is put into the container body and the lid is closed and a certain period of time elapses, the inside of the container body may be depressurized due to cooling of the beverage. In such a case, even if a user performs an operation of releasing the cover lock mechanism to fix the cover, the cover filler of the cover may adhere to the liquid passage, and the cover may not be opened.

In patent document 1, a leg portion is provided on a lock member (opening/closing operation member) of a cover lock mechanism. When the locking member is rotated about the rotation axis (swing axis) during the operation of releasing the fixed state of the cover, the leg rotates together with the locking member. Even when the pressure in the container main body is reduced, the foot portion kicks up the lid body, thereby forcibly opening the lid body.

Patent document 1: japanese patent laid-open No. 2008-125965

However, when the leg portion as in patent document 1 is provided, the following problem occurs.

When the locking member is pushed in to rotate about the rotation axis, the lid cannot be opened if the leg hits the lid before the locking member is released from the lid.

In order to prevent such a problem, it is effective to secure a large rotation range of the lock member by increasing the size of a portion of the lock member extending upward from the rotation shaft, for example, but in this case, there is a concern that the lock member may collide with lips, chin, or the like to cause a hindrance when a user drinks a beverage, or that the aesthetic appearance of the exterior design of the container may be impaired.

The inner peripheral surface of the peripheral wall portion 10a is provided with a female screw portion 12. The female screw portion 12 is screwed with the male screw portion 7 of the neck portion 2c. Thus, the cap body 10 is detachably attached to the neck portion 2c of the container body 2 by screwing.

As shown in fig. 4, a bearing portion 15 is provided on the outer peripheral surface of the peripheral wall portion 10 a. The bearing portion 15 protrudes forward from the front end portion of the peripheral wall portion 10 a. The bearing portions 15 are provided in a pair at a distance from each other in the lateral direction. Each bearing portion 15 has a plate shape (see fig. 1) extending in a direction perpendicular to a lock hinge central axis A2 described later.

Further, an urging portion accommodating wall 16 is provided on the outer peripheral surface of the peripheral wall portion 10 a. The biasing portion accommodating wall 16 protrudes forward from the front end portion of the peripheral wall portion 10 a. The biasing portion accommodating wall 16 has a U shape that is open upward when viewed from the front side. A pair of upper end portions of the biasing portion accommodating wall 16 are connected to the bearing portions 15.

As shown in fig. 3 and 9, the cover main body 10 includes: a port forming member 13 attached to the opening 10c of the cap body 10 and provided with a liquid passage port 11; and a mouth detachable mechanism 14 for detachably fixing the mouth forming member 13 to the opening 10c.

The mouth forming member 13 is detachably attached to the opening 10c, and forms a drinking mouth or an injection mouth (in this embodiment, a drinking mouth). The mouth forming member 13 has: a bottom wall portion 13a formed with a liquid passage 11; a tubular peripheral wall portion 13b rising upward from the periphery of the bottom wall portion 13 a; a lower flange portion 13c that extends radially outward from a lower end portion of the bottom wall portion 13 a; a claw portion 13e protruding forward from the outer peripheral surface of the peripheral wall portion 13 b; a pair of upper flange portions (not shown) protruding from the outer peripheral surface of the peripheral wall portion 13b to the left and right sides, respectively, and extending in the front-rear direction; and a drink opening 13d having a beveled shape, which is disposed at the upper end opening edge of the peripheral wall 13b and extends downward from the front end of the upper end opening edge toward the rear side.

The claw portion 13e is locked to the locking recess portion 10d from the upper side, and the locking recess portion 10d is recessed downward from the upper surface of the top wall portion 10b of the lid body 10. Although not particularly shown, the pair of upper flange portions are located below the claw portions 13e in the vertical direction, and contact the lower surface of the top wall portion 10b from the lower side. Thus, the mouth forming member 13 is disposed in the opening 10c in a vertically positioned state.

The mouth attaching/detaching mechanism 14 is a member for detachably attaching the mouth forming member 13 to the opening 10c of the lid body 10. The mouth attaching/detaching mechanism 14 is disposed between the mouth forming member 13 and the hinge 31 in the front-rear direction. Specifically, the opening attaching/detaching mechanism 14 is provided between the rear end portion of the inner peripheral portion of the opening 10c and the rear end portion of the peripheral wall portion 13b of the opening forming member 13.

The mouth attaching/detaching mechanism 14 is coupled to the mouth forming member 13 via an attaching/detaching shaft 17. The attachment/detachment shaft 17 extends in the left-right direction, and the mouth attachment/detachment mechanism 14 is rotatable about the central axis of the attachment/detachment shaft 17.

The mouth attaching/detaching mechanism 14 has an elastic portion (elastic piece) 14a that can be elastically deformed. The elastic portion 14a is sandwiched between the main body wall portion of the mouth attaching/detaching mechanism 14 and the rear end portion of the peripheral wall portion 13b of the mouth forming member 13.

When the lid unit 3 is assembled, the elastic portion 14a is elastically deformed so as to contract in the front-rear direction, whereby the port forming member 13 and the port attaching/detaching mechanism 14 can be fitted into the opening portion 10c. After this fitting, the elastically deformed elastic portion 14a is deformed so as to be restored to be elongated in the front-rear direction, and thus the port forming member 13 and the port attaching/detaching mechanism 14 are fitted so as to be pressed against the inner peripheral portion of the opening portion 10c, and are fixed to the opening portion 10c.

The mouth forming member 13 may be configured to be detachable from the top wall portion 10b of the cap body 10 as in the present embodiment, or may be formed integrally with the top wall portion 10 b.

As shown in fig. 3, the water stop packing 35 is detachably attached to the lower flange portion 13c of the mouth forming member 13. The water-stop packing 35 is an annular sealing member for sealing the gap between the protruding portion 8 and the mouth forming member 13. The water stop filler 35 is made of an elastic member such as a rubber having heat resistance, e.g., silicone rubber.

An inner peripheral concave portion 35a is provided on the inner peripheral portion of the water stop filler 35 over the entire periphery in the circumferential direction, and the inner peripheral concave portion 35a is recessed radially outward. The water stop filler 35 is fitted to the lower flange portion 13c through the inner peripheral recess 35a, and is attached to the mouth forming member 13.

An elastic flange portion 35b is provided on the outer peripheral surface of the water stop filler 35 so as to protrude radially outward. The elastic flange portion 35b is disposed on the outer peripheral portion of the water stop filler 35, and extends over the entire circumference in the circumferential direction. In the present embodiment, 2 elastic flange portions 35b are arranged in the vertical direction.

When the lid unit 3 is attached to the container body 2, the elastic flange 35b is elastically deformed and brought into close contact with the extension 8 of the container body 2 over the entire circumference. Thereby, the water-blocking filler 35 can seal the gap between the mouth forming member 13 (the lid body 10) and the protruding portion 8 (the container body 2) in a liquid-tight manner.

The water stop filler 35 is elastically deformed by stretching and stretching itself, and can be removed from the lower flange portion 13 c. This allows the mouth forming member 13 and the water-stop packing 35 to be washed, and the mouth forming member 13 and the water-stop packing 35 can be kept sanitary.

For example, the number of the elastic flange portions 35b is not limited to the above-described 2, but may be 1 or 3 or more. The water stop filler 35 is not limited to the structure provided with the elastic flange portion 35b described above, and may be appropriately changed in shape or the like.

As shown in fig. 3 and 9, the lid 20 opens and closes the liquid inlet 11, which is a drinking or injection port of the mouth forming member 13.

Specifically, the lid body 20 is connected to the lid body 10 via the hinge 31, thereby being rotatable about the hinge 31 between a closed state (closed position) shown in fig. 3 and an open state (open position) shown in fig. 9. The closed state (closed position) of the lid 20 shown in fig. 3 is a position where the lid 20 closes the liquid passage 11, and the open state (open position) of the lid 20 shown in fig. 9 is a position where the lid 20 opens the liquid passage 11. Fig. 8 shows a process (intermediate stage) of transition of the lid 20 from the closed state to the open state.

The lid 20 is biased by a torsion spring (not shown) provided in the hinge 31 in a direction of opening the liquid passage 11, that is, in an opening direction, around a central axis A1 of the hinge 31 (hereinafter, referred to as a hinge central axis A1). That is, the lid body 20 is rotatably attached to the lid body 10 via the hinge 31, and closes the liquid passage 11 so that the liquid passage 11 can be opened in a state where the lid body is biased in the opening direction around the hinge 31.

As shown in fig. 3 to 5, the cover 20 includes: a cover peripheral wall portion 20a formed in a substantially cylindrical shape so as to be continuous with the peripheral wall portion 10a of the cover main body 10; a lid top wall portion 20b connected to an upper end portion of the lid peripheral wall portion 20 a; and a cylindrical inner wall portion 20c protruding downward from the cover top wall portion 20 b.

A cap packing 21 is provided inside the cap body 20, and the cap packing 21 closes the liquid passage 11 of the port forming member 13. I.e. the cover 20 has a cover filler 21. The cap packing 21 is a plug-like sealing member for sealing the liquid passage 11. The cover packing 21 is made of an elastic material, and for example, the same material as the water stop packing 35 can be used.

The cover packing 21 is substantially cylindrical with a bottom, and is detachably attached to the inner wall 20c in a state where the inner wall 20c is fitted therein. The bottom surface (lower surface) of the cover packing 21 is formed in a dome shape protruding toward the lower side.

In the cap unit 3, when the upper portion of the cap body 10 is closed by the cap body 20, the cap filler 21 is elastically deformed and brought into close contact with the periphery of the liquid passage 11. This can close the liquid passage 11 of the port forming member 13.

The cover packing 21 is elastically deformed so as to expand its diameter when attached to the inner wall portion 20c, and is firmly fitted into the inner wall portion 20c on the inner side thereof, thereby being tightly fixed to the inner wall portion 20c. Therefore, even when the inside of the container body 2 is negative pressure in the closed position of the lid body 20 and a pulling force is applied to the lid filler 21 toward the inside of the container body 2, the lid filler 21 can be prevented from being separated from the inner wall portion 20c when the lid body 20 is opened. Therefore, when the lid 20 is opened, the liquid passage 11 can be opened stably.

The lid top wall portion 20b has a lid recess 20d recessed downward from the upper surface of the lid top wall portion 20 b. A cover member 22 is attached to the cover recess 20d, and the cover member 22 covers the inner wall portion 20c from above. That is, the cover 20 has a cover member 22. The cover member 22 is formed in a substantially disk shape.

The cover member 22 may be made of the same material as the cover top wall portion 20b of the cover body 20, or may be made of a different material, color, or the like. For example, a member made of a transparent material may be used as the cover member 22. Further, a three-dimensional structure may be disposed on the upper portion of the cover member 22, or the upper surface may be engraved. This can provide the cover unit 3 with excellent design.

As shown in fig. 3, the cover 20 has a pushed-up surface 20e. The pushed-up surface 20e is disposed at the front end of the cover 20. Specifically, the pushed-up surface 20e is disposed at the front lower end portion of the cover peripheral wall portion 20 a. The pushed-up surface 20e is inclined surface-like which is inclined upward as it goes rearward. In the present embodiment, the pushed-up surface 20e is formed of a flat surface.

The hinge 31 is disposed at the rear of the cover unit 3. The hinge 31 connects the rear upper end portion of the lid body 10 and the rear portion of the lid body 20 to be rotatable about the hinge center axis A1. The hinge center axis A1 extends in the left-right direction. The hinge center axis A1 is disposed on the rear side of the center axis C. The hinge center axis A1 and the center axis C are located at a twisted position with respect to each other.

The hinge 31 has a torsion spring (urging portion) not shown. The torsion spring is a torsion coil spring extending in a spiral shape around the hinge center axis A1. The torsion spring biases the lid body 20 with respect to the lid body 10 in the opening direction about the hinge 31 (about the hinge center axis A1).

The cover lock mechanism 40 is disposed at the front of the cover unit 3. The cover lock mechanism 40 fixes the cover 20 to the cover body 10 in a closing position where the cover 20 closes the liquid passage 11 against the urging force of the torsion spring of the hinge 31. The cover lock mechanism 40 fixes the front end portion of the cover main body 10 and the front end portion of the cover body 20.

Specifically, fig. 3 shows a state in which the lid body 20 in the closed state (closed position) is fixed to the lid body 10 by the lid lock mechanism 40 (i.e., a locked state of the lid lock mechanism 40). Fig. 9 shows a state in which the cover lock mechanism 40 is unlocked from the cover 20 (i.e., a state in which the cover lock mechanism 40 is unlocked). Fig. 6 shows a process (intermediate stage) of unlocking by operating the cover lock mechanism 40 in the closed state of the cover 20.

As shown in fig. 3 to 5, the cover lock mechanism 40 includes: a lock hinge 41; a locking member 42 rotatably attached to the cover body 10 via a locking hinge 41; a lock urging portion 43 that urges the lock member 42; an annular stopper 44 rotatably attached to the cover body 10 via a hinge 41; a lock receiving portion 45 for locking the lock member 42; and a stopper receiving portion 46 for hooking the annular stopper 44.

The lock hinge 41 is provided at the front end portion of the peripheral wall portion 10a of the cover main body 10. The lock hinge 41 connects the front end portion of the cover main body 10 and the lock member 42 to be rotatable about a central axis A2 of the lock hinge 41 (hereinafter referred to as a lock hinge central axis A2). The lock hinge 41 connects the front end portion of the cover main body 10 and the both end portions of the annular stopper 44 in the lateral direction so as to be rotatable about the lock hinge center axis A2.

The lock hinge center axis A2 extends in the left-right direction. In the present embodiment, the lock hinge center axis A2 and the hinge center axis A1 extend parallel to each other. The lock hinge center axis A2 is disposed on the front side of the center axis C. The locking hinge center axis A2 and the center axis C are located at a twisted position with respect to each other.

The locking hinge 41 has a rotation shaft 47. That is, the cover locking mechanism 40 has a rotation shaft 47. The rotation shaft 47 has a cylindrical shape centered on the lock hinge center axis A2, and extends in the left-right direction. The rotation shaft 47 is provided to penetrate the pair of bearing portions 15 of the cover body 10 in the left-right direction, and is supported by the pair of bearing portions 15. The rotation shaft 47 rotatably supports the lock member 42 and the annular stopper 44 about the lock hinge center axis A2.

Here, in the present embodiment, as shown in fig. 3, the cover unit 3 is viewed from the right side along the direction in which the lock hinge central axis A2 extends, and the clockwise direction of the rotation direction (around the rotation shaft 47) around the lock hinge central axis A2 is referred to as the lock direction, and the counterclockwise direction of the rotation direction is referred to as the unlock direction.

The locking direction is a direction in which (the locking member 42 of) the cover locking mechanism 40 fixes the cover 20. The unlocking direction is a direction in which the cover lock mechanism 40 is unlocked from a fixed state in which (the lock member 42 of) the cover 20 is fixed.

The locking member 42 is a member that is locked to the lid 20 to fix the lid 20 in the closed position. The lock member 42 is operated by the user when the fixed state of the lid 20 to the closed position is released. In the present embodiment, the lock member 42 has a columnar shape extending in the vertical direction as a whole.

As shown in fig. 3, 10 and 11, the lock member 42 includes: a lock bearing portion 42c supported by the rotation shaft 47 (lock hinge 41); a first extension portion 42a extending upward from the lock bearing portion 42 c; a second extension 42b extending downward from the lock bearing 42 c; a locking cover 51.

The lock bearing portion 42c, the first extension portion 42a, and the second extension portion 42b are made of, for example, resin. The lock cover 51 is made of metal such as stainless steel.

The lock bearing portion 42c is disposed at a substantially central portion of the lock member 42 in the vertical direction, and protrudes rearward from the first extension portion 42a and the second extension portion 42 b. The lock bearing portion 42c has an insertion hole 42d, and the insertion hole 42d penetrates the lock bearing portion 42c in the left-right direction. The rotation shaft 47 is inserted through the insertion hole 42d.

The first extension 42a has a columnar shape or a plate shape extending upward from a front side portion of the lock bearing portion 42c. A hook 48 is provided at an upper end of the first extension 42a so as to protrude rearward. As shown in fig. 3, the hook 48 is detachably engaged with the lock receiving portion 45 of the cover 20. That is, the locking member 42 is detachably locked to the cover 20.

As shown in fig. 10 and 11, the second extension portion 42b has a columnar shape or a plate shape extending downward from the front side portion of the lock bearing portion 42c. The second extension portion 42b has a biasing portion insertion hole 42e, and the biasing portion insertion hole 42e penetrates the second extension portion 42b in the front-rear direction.

The lock cover 51 has a front cover 51a and a pair of side covers 51b.

The front cover 51a has a plate shape extending in a direction perpendicular to the front-rear direction. In the present embodiment, the front cover 51a has a substantially oblong plate shape or a substantially rectangular plate shape extending in the up-down direction. The front cover 51a is configured to cover the front sides of the lock bearing portion 42c, the first extension portion 42a, and the second extension portion 42b.

The side cover 51b has a plate shape extending in a direction perpendicular to the lock hinge central axis A2, and has a substantially quadrangular plate shape in the present embodiment. The pair of side covers 51b are arranged at a distance from each other in the left-right direction. A pair of side covers 51b are connected to both end portions of the front cover 51a in the left-right direction. The lock bearing portion 42c is sandwiched between the pair of side covers 51b. The pair of side covers 51b covers the lock bearing portion 42c from both sides in the left-right direction.

The lock bearing portion 42c and the pair of side covers 51b are disposed between the pair of bearing portions 15 in the left-right direction (see fig. 1 and 4).

The pair of side covers 51b have cover holes 51c, respectively. Each cover hole 51c penetrates each side cover 51b in the left-right direction. The pair of cover holes 51c overlap the insertion hole 42d as viewed in the left-right direction. The rotation shaft 47 is inserted through the pair of cover holes 51c.

In the present embodiment, the lock member 42 is provided with the lock cover 51, and thereby the aesthetic appearance of the cover unit 3 can be improved. In addition, the strength of the locking member 42 can be improved.

The lock urging portion 43 is made of an elastic member such as a rubber having heat resistance, e.g., silicone rubber. That is, the lock urging portion 43 is elastically deformable. As shown in fig. 3 to 5, the lock urging portion 43 is disposed between the front end portion of the peripheral wall portion 10a of the cover main body 10 and the second extension portion 42b of the lock member 42. At least the rear end portion of the lock urging portion 43 is accommodated inside the urging portion accommodating wall 16.

As shown in fig. 6 to 9, when the user presses the second extension portion 42b of the lock member 42 toward the rear side, the lock urging portion 43 elastically deforms between the peripheral wall portion 10a and the second extension portion 42b so as to be contracted in the front-rear direction. Thereby, the lock urging portion 43 urges the second extension portion 42b toward the front side. In other words, the lock member 42 is biased by the lock biasing portion 43 in the locking direction about the rotation shaft 47 (about the lock hinge center axis A2).

In the present embodiment, as shown in fig. 3, even in a state in which the user does not push the second extension portion 42b of the lock member 42 toward the rear side, the lock urging portion 43 is slightly elastically deformed in the front-rear direction, and the lock member 42 is urged by the lock urging portion 43 in the locking direction about the rotation shaft 47.

As shown in fig. 10 and 11, the lock urging portion 43 includes an elastically deformable portion 43a and an insertion protrusion 43b.

The elastic deformation portion 43a has a columnar shape extending in the front-rear direction. The elastic deformation portion 43a is sandwiched between the peripheral wall portion 10a and the second extension portion 42b in the front-rear direction. The elastic deformation portion 43a has a hollow hole 43c. The hollow hole 43c penetrates the elastic deformation portion 43a in the left-right direction. By providing the hollow hole 43c, the elastic deformation amount of the elastic deformation portion 43a can be ensured to be large.

The insertion protrusion 43b has a columnar shape protruding forward from the elastically deforming portion 43a. The outer diameter dimension (dimension in the direction orthogonal to the front-rear direction) of the insertion protrusion 43b is smaller than the outer diameter dimension of the elastic deformation portion 43a. In other words, the elastic deformation portion 43a has a larger outer diameter than the insertion protrusion 43b. The insertion protrusion 43b is inserted into the urging portion insertion hole 42e of the second extension portion 42 b.

As shown in fig. 1, 4 and 5, the annular stopper 44 is a member that extends in a substantially circular arc shape around the upper portion of the lock member 42, and both ends thereof are rotatably supported by a rotation shaft 47 (lock hinge 41). Thus, the annular stopper 44 can rotate in the up-down direction about the lock hinge 41, specifically, in the lock direction and the unlock direction about the rotation shaft 47.

The annular stopper 44 has an annular bearing portion 44a and an annular insertion hole 44b.

The annular bearing portions 44a are provided in a pair at both end portions of the annular stopper 44. The pair of annular bearing portions 44a are arranged at a distance from each other in the left-right direction. A pair of bearing portions 15 is disposed between the pair of annular bearing portions 44a.

The annular insertion holes 44b are provided in the pair of annular bearing portions 44a, respectively. The annular insertion holes 44b penetrate the annular bearing portions 44a in the left-right direction. The rotation shaft 47 is inserted through the pair of annular insertion holes 44b.

As shown in fig. 3, the lock receiving portion 45 has a claw shape protruding forward from the front lower end portion of the cover peripheral wall portion 20a of the cover 20. The lock receiving portion 45 is disposed at the rear side of the first extension portion 42a of the lock member 42 at the closed position of the cover 20, and faces the first extension portion 42 a.

As shown in fig. 4, the stopper receiving portion 46 has a shape fitted to the inner peripheral portion of the annular stopper 44, and is provided so as to protrude forward from a position surrounding the periphery of the lock receiving portion 45 in the front end portion of the cover peripheral wall portion 20 a. The stopper receiving portion 46 is a substantially U-shaped wall portion that opens downward when viewed from the front side.

As shown in fig. 3, when the hook 48 is locked to the lock receiving portion 45, the hook 48 is inserted between the stopper receiving portion 46 and the lock receiving portion 45.

In the cover lock mechanism 40, as shown in fig. 3, when the cover 20 closes the upper portion of the cover main body 10, the hook 48 of the lock member 42 is locked to the lock receiving portion 45, whereby the state in which the cover 20 closes the upper portion of the cover main body 10, that is, the closed position of the cover 20 can be maintained. From this state, the user releases the locked state of the annular stopper 44 and the stopper receiving portion 46, and presses the second extension portion 42b of the lock member 42 rearward against the urging force of the lock urging portion 43, whereby the lock member 42 rotates about the lock hinge 41 and the first extension portion 42a is displaced forward as shown in fig. 6, whereby the locked state of the hook 48 with respect to the lock receiving portion 45 can be released. That is, the user can release the fixed state (locked state) in which the cover lock mechanism 40 fixes the cover 20 by performing an operation of rotating the lock member 42 in the unlocking direction about the rotation shaft 47. As a result, the lid 20 can be rotated in the opening direction by the biasing force of the torsion spring in the hinge 31, as shown in fig. 9.

As shown in fig. 1 and 3, in the lid lock mechanism 40, when the lid body 20 closes the upper portion of the lid body 10, the annular stopper 44 rotates in the locking direction about the rotation shaft 47 and is caught by the stopper receiving portion 46, whereby the rotation of the lid body 20 in the opening direction is prevented. Thus, in the cover lock mechanism 40, the cover 20 can be prevented from being opened by an unnecessary (unexpected) operation of the lock member 42 or the like. Further, as shown in fig. 6, the annular stopper 44 is rotated in the unlocking direction about the rotation shaft 47, whereby the locked state of the annular stopper 44 with respect to the stopper receiving portion 46 can be released.

As shown in fig. 3, the cover opening mechanism 60 is disposed at the front of the cover unit 3. The cover opening mechanism 60 has a lever portion 61, and the lever portion 61 is provided integrally with the lock member 42. The lever portion 61 is located at the rear side of the rotation shaft 47. As shown in fig. 6 to 8, the lever 61 rotates together with the lock member 42 in the unlocking direction or the locking direction about the rotation shaft 47.

As shown in fig. 10 and 11, the lever portion 61 includes a lever main body 61a, a recess 61b, and a push-up portion 61c.

The lever body 61a has a columnar shape or a plate shape extending rearward from the lock member 42. In the present embodiment, the lever main body 61a protrudes rearward from the rear upper end portion of the lock bearing portion 42c in the lock member 42.

The recess 61b is recessed downward from the upper surface of the lever main body 61 a. In the present embodiment, the concave portion 61b has a groove shape extending in the left-right direction. Both end portions of the recess 61b in the left-right direction are open at both end surfaces of the lever main body 61a in the left-right direction. The recess 61b is disposed on the rear side and the upper side of the rotation shaft 47.

As shown in fig. 3, the concave portion 61b is recessed in a direction away from a part of the front end portion of the lid body 20. Specifically, the recess 61b is recessed in a direction away from a corner (corresponding to the above-described portion) of the front lower end portion of the cover peripheral wall portion 20a of the cover 20, which is located at a connecting portion between the lower surface of the lock receiving portion 45 and the pushed-up surface 20 e.

As shown in fig. 6 and 7, in the closed position of the lid body 20, when the lever 61 rotates in the unlocking direction about the rotation shaft 47 together with the lock member 42, the corner portion at the front lower end portion of the lid peripheral wall portion 20a is accommodated in the recess portion 61b so as not to abut against the lever 61. Specifically, when the lever portion 61 rotates in the unlocking direction about the lock hinge center axis A2, the corner portion (a part) is inserted into the recess 61b, and the corner portion does not contact the recess 61b. That is, the recess 61b is configured to be able to receive a part of the front end portion of the lid 20 by non-contact.

As shown in fig. 10 and 11, the push-up portion 61c protrudes from the lever main body 61a at least toward the upper side. In the present embodiment, the push-up portion 61c protrudes upward and rearward (obliquely upward) from the rear end portion of the lever main body 61 a. However, the present invention is not limited to this, and the push-up portion 61c may protrude straight (vertically) from the lever main body 61a toward the upper side in the vertical direction, although not particularly shown.

In the present embodiment, the push-up portion 61c is a rib-like protrusion extending in the left-right direction. The push-up portion 61c is disposed adjacent to the concave portion 61b on the rear side of the concave portion 61b. As shown in fig. 3, the push-up portion 61c faces the pushed-up surface 20e of the cover 20.

At least a part of the push-up portion 61c is disposed so as to overlap with the front end portion of the lid 20 when viewed from above. Specifically, in the present embodiment, at least the front side portion of the push-up portion 61c is arranged so as to overlap the front end portion (particularly, the pushed-up surface 20 e) of the cover peripheral wall portion 20a as viewed from above. The lever portion 61 is rotated in the unlocking direction about the rotation shaft 47 together with the lock member 42, whereby the push-up portion 61c can be brought into contact with the pushed-up surface 20 e.

Specifically, when the user releases the locked state of the annular stopper 44 and the stopper receiving portion 46 from the closed position of the lid 20 shown in fig. 3 and presses the second extension portion 42b of the lock member 42 rearward, the locked state of the hook 48 with respect to the lock receiving portion 45 is released first as shown in fig. 6. Specifically, as shown in fig. 3, the state in which the lock member 42 is not pushed in is set to 0 ° (the angle at which the lever portion 61 is a horizontal reference, hereinafter referred to as a reference angle), and as shown in fig. 6, the angle at which the lock receiving portion 45 is released from the locking state of the hook portion 48 (the rotation angle from the reference angle around the lock hinge center axis A2) is set to, for example, 10 ° or less, and in the example of the present embodiment, about 8 °. At this time, if the internal pressure of the container body 2 is reduced, the cap packing 21 may adhere to the liquid inlet 11, and the cap 20 may not be opened.

In this case, when the user presses the second extension portion 42b of the lock member 42 further to the rear side, the push-up portion 61c contacts the pushed-up surface 20e as shown in fig. 7, and the push-up portion 61c pushes up the pushed-up surface 20e upward as shown in fig. 8. This can forcibly open the lid 20 (open the liquid port 11). Specifically, as shown in fig. 7, the angle at which the push-up portion 61c contacts the pushed-up surface 20e (lid 20) (the rotation angle from the reference angle about the lock hinge center axis A2) is, for example, 15 ° or less, and is larger than the angle at which the lock receiving portion 45 is released from the engagement with the hook portion 48, which is about 10 ° in the example of the present embodiment. In the case where the lid packing 21 is attached to the liquid passage 11, as shown in fig. 8, the angle at which the push-up portion 61c pushes up the push-up surface 20e (lid body 20) (the rotation angle from the reference angle about the lock hinge center axis A2) is, for example, 25 ° or less, and the lid packing 21 is separated from the liquid passage 11 by approximately 13 to 18 ° in the example of the present embodiment, and the liquid passage 11 is opened, although the state depends on the state of pressure reduction in the container main body 2. As described above, the push-up portion 61c is configured to push up the lid 20 by the rotation of the lever portion 61.

That is, the lock member 42 is rotated in the unlocking direction about the rotation shaft 47, and the lock member 42 can be further rotated in the unlocking direction from the state where the push-up portion 61c is in contact with the lid 20. In other words, from the state where the pushing-up portion 61c is in contact with the lid 20, the lock member 42 is rotated in the unlocking direction to a position where the lid 20 opens the liquid opening 11, so that the lid 20 can be pushed up.

The surface of the push-up portion 61c facing the pushed-up surface 20e is formed in a convex curved surface. Therefore, the push-up portion 61c and the pushed-up surface 20e are in point contact or line contact with each other.

In the present embodiment, as shown in fig. 6 and 7, the push-up portion 61c is configured to contact the lid 20 in a state in which the locking member 42 is rotated in the unlocking direction about the rotation shaft 47 and the locking of the locking member 42 to the lid 20 is released. That is, after the engagement between the hook 48 and the lock receiving portion 45 is released, the push-up portion 61c contacts the pushed-up surface 20 e. In other words, the push-up portion 61c does not come into contact with the pushed-up surface 20e until the engagement between the hook portion 48 and the lock receiving portion 45 is released.

As described above, in the present embodiment, the lever 61 rotates about the rotation shaft 47 in response to the operation of releasing the cover lock mechanism 40 from the fixed state in which the cover 20 is fixed, and the cover 20 in the closed position is pushed up from the lower side. That is, the lid opening mechanism 60 can open the liquid port 11 by pushing up the lid 20 in the closed position in response to an operation for releasing the lid lock mechanism 40 to fix the lid 20.

The opened lid 20 shown in fig. 9 is rotated in a direction opposite to the opening direction (closing direction) against the biasing force of the torsion spring in the hinge 31, and the hook 48 of the lock member 42 is locked to the lock receiving portion 45, whereby the lid 20 is again in a state of closing the upper portion of the lid body 10, that is, the closing position of the lid 20.

According to the lid unit 3 and the capped container 1 of the present embodiment described above, the following operational effects can be obtained.

For example, if the inside of the container body 2 is depressurized by cooling the content such as a hot beverage, the lid filler 21 of the lid 20 may adhere to the liquid inlet 11, and even if the locking member 42 is released from the locking state of the lid 20, the lid 20 may not be opened. Even in such a case, in the present embodiment, since the cover opening mechanism 60 has the lever portion 61, the lever portion 61 rotates in the unlocking direction around the rotation shaft 47 together with the lock member 42 in accordance with the operation of pushing in the second extension portion 42b of the lock member 42 to the rear side by the user, and the push-up portion 61c of the lever portion 61 pushes up the cover 20 in the closed position. This allows the lid 20 to be reliably opened to open the liquid passage 11.

That is, by one operation (one operation) of releasing the locked state of the cover lock mechanism 40, the cover 20 can be pushed up together with the release of the lock to be reliably opened. In addition, the cover opening mechanism 60 can be simply constituted.

In the present embodiment, the push-up portion 61c of the lever portion 61 protrudes at least upward from the lever main body 61a, and the lid 20 is pushed up by the rotation of the lever portion 61. Therefore, when the user presses the second extension portion 42b of the lock member 42 rearward and rotates the lever portion 61 together with the lock member 42 about the rotation shaft 47, the push-up portion 61c is reliably brought into contact with the cover 20. Specifically, by appropriately setting the protruding shape, the protruding amount, and the like of the push-up portion 61c, it is possible to avoid contact between the lid 20 and the lever portion 61 until the locking member 42 is released from locking with respect to the lid 20, and to positively bring the push-up portion 61c into contact with the lid 20 to push up the lid 20 after the locking member 42 is released from locking. Further, since the push-up portion 61c protrudes upward, the push-up dimension (push-up amount) of pushing up the lid 20 is easily ensured to be large, and thus the lid 20 can be reliably pushed up and opened by the push-up portion 61 c.

Specifically, when the lever 61 hits the cover 20 before the engagement between the hook 48 of the lock member 42 and the lock receiving portion 45 of the cover 20 is released, the following may occur: the vicinity of the lock receiving portion 45 in the front end portion of the lid 20 is sandwiched between the hook portion 48 and the lever portion 61, so that the lid 20 cannot be opened. As in the present embodiment, the provision of the protruding push-up portion 61c in the lever portion 61 can avoid the above-described drawbacks.

Further, the push-up portion 61c protrudes upward from the lever main body 61a, whereby the overall length of the lever portion 61 in the front-rear direction can be reduced to be short. Since the entire length of the lever portion 61 is reduced, the drinking mouth portion 13d of the mouth forming member 13 can be disposed further toward the front side, and the drinking convenience (feeling of use) when the user drinks the beverage can be improved. In addition, the space inside the lid unit 3 is effectively utilized, which can contribute to downsizing of the lid unit 3 (the capped container 1), and as a result, can improve the aesthetic appearance of the design.

As described above, according to the lid unit 3 and the capped container 1 of the present embodiment, even when the inside of the container body 2 is depressurized, the lid body 20 can be reliably opened, the feeling of use is good, and the aesthetic appearance of the design is improved.

In the present embodiment, the push-up portion 61c is in contact (can be in contact) with the cover 20 from a state in which the user presses the second extension portion 42b of the lock member 42 and rotates it in the unlocking direction, and the locking of the lock member 42 with respect to the cover 20 is unlocked.

Therefore, when the lock member 42 is released from the locking of the lid 20 without being depressurized in the container main body 2, the lid 20 is opened by the urging force of the torsion spring (urging portion), and the liquid passage 11 is opened. On the other hand, when the pressure in the container main body 2 is reduced, the lid 20 is attached to the liquid passage 11 at the time when the locking member 42 is released from the locking with respect to the lid 20, and the lid 20 is pushed up by the pushing-up portion 61c, so that the lid 20 is opened to open the liquid passage 11.

That is, since the push-up portion 61c pushes up the lid 20 only when the pressure in the container main body 2 is reduced, the function of the lever portion 61 (lid opening mechanism 60) can be maintained well for a long period of time by suppressing the loss of the push-up portion 61c and the like. In addition, when the pressure in the container main body 2 is not reduced, the push-up portion 61c does not contact the lid 20 and the lid 20 is opened, so that the user does not feel unnecessary operation resistance.

In the present embodiment, the push-up portion 61c of the lever portion 61 is in contact with the pushed-up surface 20e of the lid 20. The pushed-up surface 20e is an inclined surface inclined upward as it goes rearward, and by such a pushed-up surface 20e, a contact area where the push-up portion 61c for rotating about the rotation shaft 47 slides can be ensured to be large. Therefore, the pushing-up portion 61c slides on the pushed-up surface 20e while rotating, and pushes up the lid 20, so that the pushing-up function of the lid 20 is more stable. Further, by forming the inclined pushed-up surface 20e, the push-up portion 61c can be easily disposed to face the pushed-up surface 20 e. Further, since an effective free space is easily provided around the lever portion 61, the degree of freedom in the shape of the push-up portion 61c can be increased, or further miniaturization of the cover unit 3 can be achieved.

In the present embodiment, the lock member 42 is rotated in the unlocking direction, and the lock member 42 can be rotated further in the unlocking direction from the state where the push-up portion 61c is in contact with the lid 20. In other words, by the lock member 42 being rotated in the unlocking direction, the lid 20 is pushed up to the position where the lid 20 opens the liquid outlet 11 from the state where the push-up portion 61c is in contact with the lid 20.

In this case, since the user presses the locking member 42 further from the state where the push-up portion 61c is in contact with the lid body 20, the lever portion 61 (lid opening mechanism 60) reliably pushes up the lid body 20, and thus the lid body 20 can be opened stably.

In the present embodiment, the lever portion 61 has a recess 61b. When the user opens the cover 20, if the second extension portion 42b of the lock member 42 is pushed rearward, the lever portion 61 rotates in the unlocking direction together with the lock member 42, and at this time, a part of the front end portion of the cover 20 is received (accommodated) without being in contact with the recess portion 61b. Therefore, the contact between the cover 20 and the lever 61 can be more reliably suppressed until the locking member 42 is released from the locking with respect to the cover 20.

Specifically, when the lever 61 hits the lid 20 before the engagement between the hook 48 of the lock member 42 and the lock receiving portion 45 of the lid 20 is released, the vicinity of the lock receiving portion 45 at the front end portion of the lid 20 is sandwiched between the hook 48 and the lever 61, and the lid 20 cannot be opened. As in the present embodiment, providing the recess 61b in the lever portion 61 can avoid the above-described drawbacks.

Further, by providing the recess 61b in the lever 61, the length (vertical dimension) of the first extension portion 42a of the lock member 42 can be kept small, and the rotation range (movable range) in which the lock member 42 is rotated about the rotation shaft 47 can be ensured to be large. The rotation range of the lock member 42 is increased, and therefore, the hooking dimension (hooking amount) between the hook 48 and the lock receiving portion 45 can be ensured to be large. Accordingly, for example, a problem that the cover 20 is opened by an unexpected release of the lock due to an impact or the like from the outside of the container can be prevented.

When the lid 20 is rotated from the open position to the closed position and the lid 20 is held in a fixed state by the lid lock mechanism 40, the lid 20 is pushed in from above. At this time, since the lid packing 21 is elastically deformed by abutting against the bottom wall portion 13a of the mouth forming member 13, there is a possibility that the lower end side of the lid body 20 abuts against the lever portion 61 of the locking member 42 depending on the amount of press-fitting. As in the present embodiment, providing the recess 61b in the lever portion 61 can avoid the above-described drawbacks.

Further, since the length of the first extension portion 42a can be reduced, it is possible to prevent the locking member 42 from coming into contact with the lips, chin, or the like and becoming blocked when the user drinks the content. In addition, the length of the first extension portion 42a is reduced, and thereby the aesthetic appearance of the container design can be improved.

In the present embodiment, the recess 61b of the lever portion 61 is formed to be recessed downward from the upper surface of the lever main body 61 a. The excellent operation and effect described above can be obtained by the concave portion 61b, and the concave portion 61b can be simply constituted.

In the present embodiment, at least a part of the push-up portion 61c is disposed so as to overlap the front end portion of the lid 20 when viewed from above.

In this case, since at least a part of the push-up portion 61c is disposed immediately below the front end portion of the cover 20, the amount of protrusion of the lever portion 61 from the locking member 42 to the rear side is suppressed to be smaller. That is, the entire length of the lever portion 61 in the front-rear direction is reduced, and accordingly, the drinking opening portion 13d of the opening forming member 13 can be disposed further toward the front side, whereby the convenience of drinking (feeling of use) when the user drinks the beverage can be improved. In addition, the space inside the lid unit 3 is effectively utilized, and thus the miniaturization of the lid unit 3 (the capped container 1) can be facilitated.

In the present embodiment, the state in which the second extension portion 42b of the lock member 42 is not pushed in is set to 0 ° (reference angle) as shown in fig. 3, and the angle (rotation angle from the reference angle about the lock hinge center axis A2) when the locked state of the lock receiving portion 45 and the hook portion 48 is released (rotation angle from the reference angle about the lock hinge center axis A2) is set to 10 ° -or less as shown in fig. 6, and the angle (rotation angle from the reference angle about the lock hinge center axis A2) at which the push-up portion 61c contacts the push-up surface 20e (cover 20) is set to be larger than the angle at which the locked state of the lock receiving portion 45 and the hook portion 48 is released and is set to 15 ° -or less as shown in fig. 7, and the angle (rotation angle from the reference angle about the lock hinge center axis A2) at which the push-up portion 61c pushes up the push-up surface 20e (cover 20) to open the liquid passage port 11 is set to 25 ° -or less as shown in fig. 8.

In this case, the pressing amount of the lock member 42 can be suppressed to be small and the liquid passage 11 can be reliably opened, so that the operability is good.

The present invention is not limited to the above-described embodiments, and, for example, as described below, structural changes and the like can be made without departing from the gist of the present invention.

In the above-described embodiment, the pushed-up surface 20e of the cover 20 is planar, and the portion of the push-up portion 61c of the lever portion 61 facing the pushed-up surface 20e is convex curved, but the present invention is not limited thereto. For example, the pushed-up surface 20e may be formed in a convex curved surface, and a portion of the push-up portion 61c facing the pushed-up surface 20e may be formed in a flat surface. Alternatively, both the pushed-up surface 20e and the portion of the push-up portion 61c facing the pushed-up surface 20e may have a convex curved surface shape.

In the above-described embodiment, the concave portion 61b of the lever portion 61 is exemplified as a groove shape extending in the left-right direction, but is not limited thereto. The concave portion 61b may be, for example, a hole. The upper surface side of the lever body 61a of the lever portion 61 may have a flat shape without the recess 61 b. That is, when the lock member 42 is rotated in the unlocking direction, the other portion of the lever body 61a may not contact the pushed-up surface 20e until the push-up portion 61c of the lever portion 61 contacts the pushed-up surface 20 e.

In the above-described embodiment, the present invention is applied to the container 1 with the lid having the heat-insulating and cold-insulating function by the container body 2 having the vacuum heat-insulating structure, but the present invention is not limited to this. That is, the present invention can be widely applied to a container with a cap in which a cap unit is detachably attached to a neck portion of a container body.

The present invention can be combined with the respective structures described in the above embodiments, modifications, and the like without departing from the gist of the present invention, and can be additionally, omitted, substituted, and changed in structure. The present invention is not limited to the embodiments and the like described above, but only by the claims.
