The cap unit 1A includes a cylindrical, i.e., a top-cylindrical, cap body 10 having a top wall (ceiling wall), a top-cylindrical lid body 20, a first hinge (hinge) 30 that rotatably connects the lid body 20 to the cap body 10, a biasing portion 60, a waterproof seal 40 that seals between the container body 2 and the cap body 10, and a lid locking mechanism 50.

The cap unit 1A and the container body 2 are coaxially arranged with the center axis C as a center.

In the present embodiment, the direction in which the central axis C extends is referred to as the vertical direction. In the vertical direction, a direction from the bottom surface portion 2a of the container body 2 toward the lid top wall portion 20a of the lid body 20 is referred to as an upper side, and a direction from the lid top wall portion 20a toward the bottom surface portion 2a is referred to as a lower side.

The direction perpendicular to the central axis C is referred to as a radial direction. In the radial direction, a direction approaching the central axis C is referred to as a radial inner side or simply an inner side, and a direction away from the central axis C is referred to as a radial outer side or simply an outer side.

The direction of the circumferential direction around the central axis C is referred to as a circumferential direction.

In addition, a direction passing through the first hinge 30 and the center axis C in the radial direction is referred to as a front-rear direction. In the front-rear direction, a direction from the first hinge 30 toward the center axis C is referred to as a front side, and a direction from the center axis C toward the first hinge 30 is referred to as a rear side.

In addition, a direction orthogonal to the front-rear direction in the radial direction is referred to as a left-right direction. As shown in fig. 2, when the beverage container 100 is in an upright posture in which the lid top wall portion 20a of the lid body 20 is oriented upward in the vertical direction as viewed from the front side, the leftward direction in the right-left direction is referred to as the left side, and the rightward direction is referred to as the right side. The posture (state) of the beverage container 100 in which the lid top wall portion 20a of the lid body 20 is oriented vertically downward is referred to as an inverted posture, although not particularly shown.

The center axis C may be referred to as a cap center axis C or a container center axis C, separately from a spout center axis, a hinge center axis a, and the like, which will be described later.

As shown in fig. 3 and 4, the hinge center axis a of the first hinge 30 extends in the left-right direction. The hinge center axis a is disposed rearward of the center axis C. The central axis C and the hinge central axis a are in a twisted position with respect to each other.

The opposing wall portion 19 is arranged in parallel with the connecting wall portion 18b of the first bearing portion 18 in the left-right direction.

The opposing wall portion 19 has a rear surface 19a facing the rear side. In the present embodiment, the rear surface 19a has an inclined plane shape extending rearward as it goes downward. Specifically, the rear surface 19a has a concave curved surface shape centering on the hinge center axis a. That is, in the vertical cross section shown in fig. 5, the rear surface 19a has a concave arc shape centering on the hinge center axis a.

As shown in fig. 4, in the present embodiment, a pair of opposing wall portions 19 are provided at a distance from each other in the left-right direction. The left (one) opposing wall portion 19 of the pair of opposing wall portions 19 is disposed adjacent to the left side of the connecting wall portion 18b of the first bearing portion 18. The right (other) opposing wall portion 19 of the pair of opposing wall portions 19 is disposed adjacent to the right side of the connecting wall portion 18b of the first bearing portion 18.

In the present embodiment, the opposing wall portion 19 and the connecting wall portion 18b of the first bearing portion 18 are connected to each other. Specifically, the right end of the left opposing wall portion 19 of the pair of opposing wall portions 19 is connected to the left lower end of the connecting wall portion 18b of the first bearing portion 18. Further, of the pair of opposed wall portions 19, the left end portion of the right opposed wall portion 19 is connected to the right lower end portion of the connecting wall portion 18b of the first bearing portion 18.

As shown in fig. 3, the lid body 20 is disposed on the upper side of the cap body 10. The lid body 20 covers the upper portion of the cap main body 10 and openably and closably covers the liquid inlet 12 and the vent hole 13. The lid 20 has a portion made of a heat-resistant resin such as polypropylene (PP) (e.g., a portion other than the liquid flow blocking portion 21, the air flow blocking portion 22, and the cover member 24, which will be described later). As shown in fig. 3 to 5, the lid body 20 includes a lid top wall portion 20a, a lid peripheral wall portion 20b, a liquid-passage closing portion 21, a gas-passage closing portion 22, a second bearing portion (contact portion) 23, and a cover member 24.

The cap top wall portion 20a is disposed above the top wall portion 10a of the cap body 10. In the present embodiment, the lid top wall portion 20a is plate-shaped extending in the front-rear direction, and is inclined upward as it goes from the first hinge 30 toward the front side.

As shown in fig. 3, the lid top wall portion 20a has: a hole 20c vertically penetrating the lid top wall 20a; and a support tube 20d projecting downward from the cover top wall portion 20a and disposed between the hole portion 20c and the first hinge 30 in the front-rear direction.

The lid peripheral wall portion 20b is a cylindrical shape extending downward from the outer peripheral portion of the lid top wall portion 20a. The cap peripheral wall portion 20b is disposed so as to surround the top wall portion 10a of the cap body 10.

The liquid passage closing portion 21 is made of an elastic member such as heat-resistant rubber, e.g., silicone rubber, or elastomer. That is, the liquid passage blocking portion 21 can be elastically deformed. The liquid passage sealing portion 21 is detachably attached to the lid top wall portion 20a of the lid body 20. When the lid body 20 is in the closed state, the liquid passage closing portion 21 is in liquid-tight contact with the upper opening portion of the spout portion 11. Thereby, the liquid passage blocking portion 21 blocks the liquid passage port 12 so as to be openable from the upper side. The liquid passage closing portion 21 is a plug-shaped sealing member that closes the liquid passage port 12 of the spout portion 11.

The liquid passage closing portion 21 has: a shaft portion 21a fitted in the hole portion 20c; and a plug portion 21b connected to a lower end portion of the shaft portion 21a and formed in a substantially dome shape that is convex downward. The liquid passage blocking portion 21 is detachable from the hole portion 20 c. Therefore, the lid body 20 and the liquid passage blocking portion 21 can be cleaned separately, and the space between the lid body 20 and the liquid passage blocking portion 21 can be maintained hygienically.

In the cap unit 1A, when the lid body 20 is at the closing position shown in fig. 3, the plug portion 21b of the liquid passage closing portion 21 abuts on the periphery of the opening portion of the liquid passage port 12, which is the upper end opening edge of the spout portion 11, and the plug portion 21b is elastically deformed and brought into close contact with the periphery of the opening portion of the liquid passage port 12. This allows the liquid passage closing portion 21 to close the liquid passage port 12 of the spout portion 11.

The vent closing portion 22 is made of an elastic member such as heat-resistant rubber, e.g., silicone rubber, or elastomer. That is, the vent closing portion 22 can be elastically deformed. The ventilation seal portion 22 is detachably attached to the lid top wall portion 20a of the lid body 20. When the lid body 20 is in the closed state, the vent closing portion 22 is in liquid-tight contact with the upper opening of the vent hole 13. Thereby, the vent closing portion 22 closes the vent hole 13 so as to be openable from the upper side. The vent closing portion 22 is a bottomed cylindrical sealing member that closes the vent hole 13.

The ventilation closing portion 22 is externally fitted to the support tube 20d. The vent closing portion 22 is detachably attached to the support tube 20d. Therefore, the lid body 20 and the vent closing portion 22 can be cleaned separately, and the space between the lid body 20 and the vent closing portion 22 can be hygienically maintained.

In this cap unit 1A, when the lid body 20 is at the closing position, the bottom of the vent closing portion 22 abuts against the periphery of the opening of the vent hole 13, and this bottom is elastically deformed and brought into close contact with the periphery of the opening of the vent hole 13. Thereby, the vent hole 13 can be closed by the vent closing portion 22.

In the present embodiment, the liquid passage blocking portion 21 and the air passage blocking portion 22 are integrally formed of a single member. Therefore, the number of components can be reduced, and the loss of components during cleaning or the like can be suppressed.

As shown in fig. 5, the second bearing portion 23 is disposed at the rear end portion of the lid body 20. Specifically, the second bearing portion 23 is disposed at the rear end portion of the lid top wall portion 20a and the rear end portion of the lid peripheral wall portion 20b, and projects downward from the lid top wall portion 20a and radially inward from the lid peripheral wall portion 20 b.

As shown in fig. 4, the second bearing portion 23 is substantially cylindrical extending along the hinge center axis a of the first hinge 30, and is disposed coaxially with the bearing cylindrical portion 18a of the first bearing portion 18. The second bearing portion 23 is arranged in parallel with the bearing tube portion 18a of the first bearing portion 18 in the left-right direction.

In the present embodiment, a pair of second bearing portions 23 are provided at a distance from each other in the left-right direction. Of the pair of second bearing portions 23, the left (one) second bearing portion 23 is disposed adjacent to the left side of the bearing tube portion 18a of the first bearing portion 18. The right (other) second bearing portion 23 of the pair of second bearing portions 23 is disposed adjacent to the right side of the bearing tube portion 18a of the first bearing portion 18.

As shown in fig. 5, the second bearing portion 23 faces the facing wall portion 19 from the rear side. In other words, the facing wall 19 faces the second bearing portion 23 from the front side. In the present embodiment, a gap of a dimension L1 is provided between the opposing wall portion 19 and the second bearing portion 23 in the front-rear direction. More specifically, a gap of a dimension L1 in the hinge radial direction, which is constant in the hinge circumferential direction, is provided between the rear surface 19a of the opposing wall portion 19 and the outer peripheral surface of the second bearing portion 23.

For example, when the lid body 20 is displaced to the front side by an impact such as dropping, the second bearing portion 23 abuts against the opposing wall portion 19 from the rear side.

As shown in fig. 4, the left (one) opposing wall portion 19 of the pair of opposing wall portions 19 is opposed to the left (one) second bearing portion 23 of the pair of second bearing portions 23 from the front side. Further, the right (other) opposing wall portion 19 of the pair of opposing wall portions 19 faces the right (other) second bearing portion 23 of the pair of second bearing portions 23 from the front side. That is, in the present embodiment, the opposing wall portions (abutted portions) 19 and the second bearing portions (abutting portions) 23 which face each other are provided on both sides in the left-right direction around the central axis C of the cap unit 1A.

The cover member 24 is a substantially cylindrical or substantially annular plate-shaped member centered on the hinge center axis a (see fig. 7). The cover member 24 is disposed adjacent to one of the pair of second bearing portions 23 in the left-right direction. The cover member 24 can be preferably made of a material different from that of the second bearing portion 23, for example, a material having excellent wear resistance as compared with the second bearing portion 23, such as Polyacetal (POM) or Acrylonitrile Butadiene Styrene (ABS).

As shown in fig. 4, in the present embodiment, the cover member 24 is provided between the right (the other) second bearing portion 23 of the pair of second bearing portions 23 and the bearing tube portion 18a of the first bearing portion 18. The cover member 24 and the other second bearing portion 23 are locked to each other while restricting relative movement in the hinge circumferential direction. The cover member 24 and the bearing cylinder portion 18a are rotatable in the hinge circumferential direction, specifically, slidably in contact with each other.

As shown in fig. 3, the first hinge 30 is disposed at the rear of the cap unit 1A. The first hinge 30 connects the upper rear end portion of the cap body 10 and the rear end portion of the lid body 20 to be relatively rotatable in the hinge circumferential direction. The lid body 20 is connected to the cap main body 10 via the first hinge 30, and thereby freely rotates between a position (closed position) for closing the liquid passage port 12 and the vent hole 13 shown in fig. 3 and a position (open position) for opening the liquid passage port 12 and the vent hole 13 shown in fig. 4.

The first hinge 30 has a hinge shaft 31 that pivotally supports the first bearing portion 18 and the second bearing portion 23 to freely rotate about a hinge center axis a. The hinge shaft 31 is in the shape of a shaft extending in the left-right direction, and is inserted through the bearing tube 18a of the first bearing 18, the pair of second bearing 23, the cover member 24, and the biasing portion 60 (see fig. 7). The hinge shaft 31 is, for example, a shaft, a tube, or the like made of stainless steel.

The biasing portion 60 biases the lid body 20 with respect to the cap body 10 in an opening direction around the first hinge 30 (i.e., in the hinge circumferential direction) (see fig. 7). In the present embodiment, the biasing portion 60 is provided in the first hinge 30. The biasing portion 60 is a torsion coil spring extending spirally about the hinge center axis a. In the present embodiment, the biasing portion 60 is disposed over the inside of the bearing tube portion 18a of the first bearing portion 18 and the inside of the cover member 24, and biases the lid body 20 in the opening direction by biasing the other second bearing portion 23 in the hinge circumferential direction with respect to the first bearing portion 18 via the cover member 24. When the locked state by the cover lock mechanism 50 is released by this biasing force, the lid body 20 pivots about the first hinge 30 from the closed position toward the open position.

As shown in fig. 3, the waterproof seal 40 is detachably attached to the inside of the cap body 10. The waterproof seal 40 is an annular sealing member that seals (prevents water) the space between the container body 2 and the cap body 10, and is made of, for example, a heat-resistant rubber such as silicone rubber, or an elastic member such as an elastomer. That is, the waterproof seal 40 can be elastically deformed. Specifically, the waterproof seal 40 of the present embodiment closes the space between the upper opening portion 2d of the container body 2 and the top wall portion 10a of the cap body 10 in a liquid-tight manner.

In fig. 3, a part of the waterproof seal 40 is shown by a two-dot chain line (imaginary line) as a shape before elastic deformation.

The waterproof seal 40 is attached to the cap body 10 in a state of being fitted to the cylindrical portion 14. In addition, the waterproof seal 40 is detachable from the tube portion 14. Thereby, the cap body 10 and the waterproof seal 40 can be cleaned separately, and the gap between the cap body 10 and the waterproof seal 40 can be sanitarily held.

The waterproof seal 40 has: a cylindrical seal peripheral wall 41 externally fitted to the cylindrical portion 14; an annular seal flange 42 that extends radially outward from the seal peripheral wall 41 and seals a space between the upper opening 2d of the container body 2 and the top wall 10a of the cap body 10; and an extending projecting collar portion 43 extending and projecting radially inward from the lower end portion of the seal peripheral wall 41.

The seal peripheral wall 41 extends in the vertical direction about the central axis C and is fitted to the outside of the tube portion 14. The inner peripheral surface of the seal peripheral wall 41 contacts the outer peripheral surface of the tube portion 14. The lower end of the seal peripheral wall 41 protrudes downward beyond the lower end of the tube 14.

The seal flange 42 has a substantially annular plate shape centered on the central axis C. The seal flange 42 protrudes radially outward from the upper end of the seal peripheral wall 41 and extends in the circumferential direction.

As indicated by the two-dot chain line in fig. 3, in the present embodiment, the seal flange 42 includes: a groove portion 42a recessed radially inward from the outer peripheral surface of the seal flange 42 and extending in the circumferential direction; and a pair of flange portions 42b disposed above and below the groove portion 42 a. Therefore, the cross-sectional shape (vertical cross-sectional shape) of the seal flange 42 parallel to the central axis C is substantially C-shaped or substantially U-shaped, which is open to the outside in the radial direction.

The upper surface of the upper flange portion of the pair of flange portions 42b contacts the lower surface of the ceiling wall portion 10 a. That is, the upper surface of the seal flange 42 is in contact with the lower surface of the top wall portion 10 a. One of the pair of flange portions 42b is thinner (plate thickness) than the seal peripheral wall 41. The pair of flange portions 42b are also easily elastically deformed particularly in the waterproof seal 40, and easily come into close contact with the upper opening portion 2d and the ceiling wall portion 10a, respectively, so that the space therebetween can be stably closed.

The extended projecting brim portion 43 has a circular plate shape centered on the center axis C. The extending projecting brim portion 43 projects radially inward from the lower end portion of the seal peripheral wall 41 and extends in the circumferential direction. The extended protruding collar portion 43 is disposed directly below the peripheral wall of the tube portion 14. A gap is provided in the vertical direction between the upper surface of the extended projecting collar portion 43 and the lower end surface of the tube portion 14. Therefore, it is possible to prevent the extended projecting bead portion 43 from first coming into contact with the lower end surface of the tube portion 14 due to, for example, a manufacturing error of a component at the time of assembling the waterproof seal 40, and to prevent a problem that the close contact state between the seal flange 42 and the top wall portion 10a becomes unstable.

As shown in fig. 1, 3, and 4, the cover lock mechanism 50 is disposed in the front portion of the cap unit 1A. The lid lock mechanism 50 fixes the lid body 20 to the above-described closed position (closed state) with respect to the cap body 10 against a rotational urging force in the opening direction about the first hinge 30 (hinge center axis a). The cap lock mechanism 50 fixes the distal end portion of the cap body 10 and the distal end portion of the lid body 20. Fig. 1 and 3 show a state (locked state) in which the lid body 20 is fixed at the closing position by the lid lock mechanism 50, and fig. 4 shows a state (unlocked state) in which the lid body 20 is released from the lid lock mechanism 50.

The lid lock mechanism 50 has: a second hinge 55 having a hinge center axis (not shown) extending in the left-right direction; a lock member 52 rotatable about a hinge center axis of the second hinge 55; and a ring stopper (locking part) 54 that is rotatable about the hinge center axis of the second hinge 55. In addition, the second hinge 55 has: an inner hinge part 51; and outer hinge portions 53 located on both outer sides of the inner hinge portion 51 in the left-right direction. The inner hinge portion 51 and the outer hinge portion 53 are disposed coaxially with each other with the hinge center axis of the second hinge 55 as a common axis.

The lock member 52 is rotatably (swingably) attached to the cap body 10 via the inner hinge portion 51. The ring stopper 54 is rotatably attached to the cap body 10 via the outer hinge 53. That is, the locking member 52 and the ring stopper 54 are provided to the cap body 10, respectively.

The inner hinge portion 51 is provided on the front surface of the peripheral wall portion 10b of the cap body 10. The inner hinge portion 51 is disposed inside the outer hinge portion 53 (i.e., on the center axis C side) in the left-right direction. The lock member 52 is supported by the inner hinge portion 51 so as to be rotatable in the front-rear direction. The lock member 52 has: an upper arm portion 52a extending upward from the hinge center axis of the second hinge 55; and a lower arm portion 52b extending downward from the hinge center axis of the second hinge 55. A hook portion (locking portion) 56 is provided at the tip of the upper arm portion 52a (the upper end of the lock member 52) so as to protrude rearward. That is, the hook 56 is disposed on the lock member 52, and the hook 56 is provided to the cap body 10 via the lock member 52 and the inner hinge 51. A compression coil spring 57 is provided between the lower arm portion 52b and the peripheral wall portion 10b in a state of being compressed in the front-rear direction.

The outer hinge portion 53 is provided on the front surface of the peripheral wall portion 10b of the cap main body 10. The ring stopper 54 is formed of a curved substantially C-shaped member, and both ends thereof are supported by the outer hinge 53 to be rotatable in the vertical direction.

Further, the cover locking mechanism 50 includes: a lock receiving portion (locked portion) 58 to which the hook portion 56 of the locking member 52 is locked; and a stopper receiving portion (engaged portion) 59 for receiving the ring stopper 54. The lock receiving portion 58 is in the shape of a claw protruding forward from a lower end portion on the front side of the cover body 20. The stopper receiving portion 59 is formed in a substantially semicircular ring shape that is adapted to the shape of the inner peripheral portion of the ring stopper 54, and protrudes forward from a position surrounding the lock receiving portion 58 in the front surface of the cover body 20. That is, the lock receiving portion 58 and the stopper receiving portion 59 are provided in the lid body 20, respectively.

More specifically, the lid lock mechanism 50 includes: a lock receiving portion (engaged portion) 58 provided in one of the cap body 10 and the lid body 20 (the lid body 20 in the present embodiment); and a hook portion (locking portion) 56 provided on the other of the cap body 10 and the lid body 20 (the cap body 10 in the present embodiment) and locked to the lock receiving portion 58 from the front side. The lower surface of the hook 56 is locked to the upper surface of the lock receiving portion 58 so as to be movable in the front-rear direction.

Further, the lid lock mechanism 50 includes: a stopper receiving portion (engaged portion) 59 provided in one of the cap body 10 and the lid body 20 (the lid body 20 in the present embodiment); and a ring stopper (locking portion) 54 provided on the other of the cap body 10 and the lid body 20 (the cap body 10 in the present embodiment) and locked to the stopper receiving portion 59 from the front side. The inner peripheral portion of the ring stopper 54 is locked to the outer peripheral portion of the stopper receiving portion 59 so as to be movable in the front-rear direction.

As shown in fig. 3 and 5, in the locked state in which the lid body 20 is fixed at the closed position by the lid lock mechanism 50, a dimension L1 in the front-rear direction between the opposing wall portion (abutted portion) 19 and the second bearing portion (abutting portion) 23 is small with respect to a gap dimension L2 in the front-rear direction between the lock member 52 and the lid body 20. Specifically, in the present embodiment, the clearance dimension L2 is a dimension (so-called "play dimension") L2 of the clearance in the front-rear direction between the rear surface of the portion of the upper arm portion 52a of the lock member 52 excluding the hook portion 56 and the front end of the lock receiving portion 58.

In the lid lock mechanism 50, when the lid body 20 is at the closed position, the hook portion 56 of the lock member 52 is locked to the lock receiving portion 58, and thereby the lid body 20 is fixed to the cap body 10 against the rotational biasing force of the first hinge 30 in the opening direction.

From this state, the user compresses the compression coil spring 57 and pushes the lower arm portion 52b of the lock member 52 rearward, thereby releasing the hook portion 56 from being locked to the lock receiving portion 58. This allows the lid body 20 biased in the opening direction to rotate toward the open position.

In the lid lock mechanism 50, when the lid body 20 is at the closing position, the ring stopper 54 is hooked (locked) to the stopper receiver 59, and rotation of the lid body 20 in the opening direction is prevented. Thus, in the cover lock mechanism 50, the cover body 20 can be prevented from being opened by an unnecessary (unintentional) operation of the lock member 52 or the like.

In the cap unit 1A and the beverage container 100 of the present embodiment described above, when an impact is applied from the first hinge 30 side (rear side) due to, for example, dropping or the like, the lid body 20 is displaced forward, and the second bearing portion (abutting portion) 23 of the lid body 20 abuts against the opposing wall portion (abutted portion) 19 of the cap body 10. The abutting portion 23 abuts against the abutted portion 19 to receive the impact, thereby suppressing further displacement of the lid body 20 toward the front side. The amount of displacement of the lid body 20 to the front side can be suppressed small, and therefore, the locked state of the lid body 20 by the lid lock mechanism 50 can be suppressed from being unintentionally released.

More specifically, since the amount of displacement of the cover body 20 toward the front side is suppressed to be small, the locked state of the lock receiving portion 58 and the hook portion 56 is maintained well. In addition, the locking state of the stopper receiving portion 59 and the ring stopper 54 is maintained well.

As described above, according to the present embodiment, even if an impact is applied by dropping or the like, the locked state of the lid body 20 can be maintained satisfactorily, and the beverage can be prevented from leaking to the outside of the container.

In the present embodiment, when the cover body 20 is in the locked state, the dimension L1 in the front-rear direction provided between the abutted portion 19 and the abutting portion 23 is made smaller than a gap dimension L2 in the front-rear direction provided between the lock member 52 and the cover body 20, that is, a so-called "play dimension" L2. Therefore, when the lid body 20 is displaced to the front side by an impact due to dropping or the like, the abutted portions 19 first abut against the abutting portions 23, and the lid body 20 is prevented from being displaced to the front side beyond the clearance dimension L2 with respect to the lock member 52 and abutting against the front side. The locked state of the hook portion 56 of the lock member 52 and the lock receiving portion 58 of the lid body 20 is maintained well, and therefore, the locked state of the lid body 20 can be more stably suppressed from being unintentionally released.

Further, although not particularly shown, when a gap dimension (play dimension) in the front-rear direction is provided between the ring stopper portion 54 and the cover peripheral wall portion 20b in the locked state of the cover body 20, the dimension L1 in the front-rear direction between the opposing wall portion (abutted portion) 19 and the second bearing portion (abutting portion) 23 is made smaller than the gap dimension, whereby the locked state between the stopper portion receiving portion 59 and the ring stopper portion 54 can be maintained satisfactorily as described above.

In the present embodiment, since the opposing wall portion 19 faces the second bearing portion 23 from the front side, even when an impact is applied from the first hinge 30 side (rear side) in the open state of the lid body 20 at the open position, the impact can be received by the abutment of the opposing wall portion 19 and the second bearing portion 23. Therefore, the strength of the cap unit 1A in the vicinity of the first hinge 30 is increased, and damage to the first hinge 30 and the like due to dropping and the like can be suppressed.

In the present embodiment, the opposing wall portion 19 and the connecting wall portion 18b of the first bearing portion 18 are connected to each other.

In this case, the strength of the first bearing portion 18 is increased by the opposing wall portion 19, and as a result, breakage of the first hinge 30 and the like can be further suppressed. Further, the rigidity of the first bearing portion 18 is increased, so that the amount of displacement of the lid body 20 toward the front side is suppressed to be small, and as a result, the operation and effect of the present embodiment described above are more stably exhibited.

In the present embodiment, in the vertical cross-section shown in fig. 5, the rear surface 19a of the opposing wall portion 19 has a concave arc shape centered on the hinge center axis a, that is, the rear surface 19a has a concave curved surface shape extending in the hinge circumferential direction.

In this case, the effect of receiving the second bearing portion 23 by the opposing wall portion 19 is more stable.

In the present embodiment, the opposing wall portions (abutted portions) 19 and the second bearing portions (abutting portions) 23 are provided on both sides in the left-right direction with respect to the center axis C of the cap unit 1A.

In this case, not only is the amount of displacement of the lid body 20 to the front side suppressed to be small, but also in the case where the lid body 20 is displaced so as to rotate (twist in the left-right direction) from the first hinge 30 in a plan view, an impact can be received by the pair of the opposing wall portions (abutted portions) 19 on either the left or right side and the second bearing portions (abutting portions) 23 coming into abutment, and therefore the amount of displacement can be suppressed to be small. Therefore, the above-described operational effect of the present embodiment is more remarkable, and the breakage of the first hinge 30 and the like due to the torsional displacement (deformation) of the lid body 20 can be suppressed.

< second embodiment >

Next, a cap unit 1B according to a second embodiment of the present invention and a beverage container 100 including the cap unit 1B will be described with reference to fig. 6 and 7. In the present embodiment, the same components as those of the above-described embodiment are denoted by the same names, reference numerals, and the like, and description thereof is omitted.

Fig. 6 shows an open state in which the lid 20 is in the open position, and fig. 7 shows a closed state in which the lid 20 is in the closed position. Fig. 7 is a sectional perspective view including a cross section perpendicular to the center axis C (not shown).

As shown in fig. 6 and 7, in the present embodiment, the cap body 10 has a first wall portion (abutted portion) 70 facing the rear side. The first wall portion 70 is a wall portion provided on the top wall portion 10a, protrudes upward, and extends in the left-right direction. In the present embodiment, the first wall portion 70 is disposed between the spout portion 11 (liquid passage port 12) and the vent hole 13 in the front-rear direction.

The lid body 20 further includes a second wall portion (abutting portion) 71, and the second wall portion (abutting portion) 71 abuts against the first wall portion 70 from the rear side after the lid body 20 is displaced toward the front side by an impact due to dropping or the like. The second wall portion 71 is a rib-shaped portion that protrudes inward from the inner peripheral surface of the cover peripheral wall portion 20b and extends in the vertical direction. In the illustrated example, the protruding amount of the second wall portion 71 protruding inward from the inner peripheral surface of the cap peripheral wall portion 20b increases toward the lower side (the cap body 10 side). The second wall portion 71 may face the first wall portion 70 with a gap therebetween at the closing position (closed state) of the lid body 20, or may be in contact therewith as long as the dimensions can be accurately controlled.

Specifically, as shown in fig. 7, in the locked state in which the lid body 20 is fixed at the closed position by the lid lock mechanism 50, the dimension L1 in the front-rear direction between the first wall portion (contacted portion) 70 and the second wall portion (contacted portion) 71 is smaller than the above-described gap dimension L2 (see fig. 3).

The first wall portion 70 and the second wall portion 71 facing each other are provided on both sides in the left-right direction around the center axis C of the cap unit 1B.

According to the cap unit 1B and the beverage container 100 of the present embodiment described above, the same operational effects as those of the above-described embodiments can be obtained.

In the present embodiment, the contact position between the first wall portion (contacted portion) 70 and the second wall portion (contact portion) 71 can be arranged at a position on the front side of the contact position between the opposing wall portion (contacted portion) 19 and the second bearing portion (contact portion) 23 in the first embodiment. That is, the abutting position can be disposed closer to the lid lock mechanism 50, and thus the locked state of the lid lock mechanism 50 with respect to the lid body 20 can be more stably suppressed from being unintentionally released.

< third embodiment >

Next, a cap unit 1C according to a third embodiment of the present invention and a beverage container 100 including the cap unit 1C will be described with reference to fig. 8 and 9. In the present embodiment, the same components as those in the above-described embodiments are denoted by the same names, reference numerals, and the like, and the description thereof is omitted.

Fig. 8 shows an open state in which the lid 20 is in the open position, and fig. 9 shows a closed state in which the lid 20 is in the closed position.

As shown in fig. 8 and 9, in the present embodiment, the cap body 10 has a rib (contacted portion) 72 that protrudes upward from the top wall portion 10a and extends in the left-right direction. In the illustrated example, the rib 72 and the mouthpiece 11 (liquid passage port 12) are arranged in parallel in the left-right direction.

The lid 20 has a groove portion (contact portion) 73 that is locked to the rib 72 at a closing position (closed state) of the lid 20. The groove portion 73 is recessed from the lower end surface of the cover peripheral wall portion 20b toward the upper side, and extends in the left-right direction. The groove 73 penetrates the lid peripheral wall portion 20b in the left-right direction, and opens on the outer peripheral surface and the inner peripheral surface of the lid peripheral wall portion 20 b.

When the lid 20 is displaced to the front side by an impact due to dropping or the like, the groove 73 abuts against the rib 72 from the rear side. The groove 73 may face the rib 72 with a gap in the closed position (closed state) of the lid body 20, or may be in contact with (fitted to) the rib as long as the dimension can be accurately controlled.

Specifically, as shown in fig. 9, in the locked state in which the lid body 20 is fixed at the closed position by the lid lock mechanism 50, the dimension L1 in the front-rear direction between the rib portion (contacted portion) 72 and the groove portion (contacted portion) 73 is smaller than the above-described gap dimension L2 (see fig. 3).

The pair of the rib 72 and the groove 73 facing each other is provided on both sides in the left-right direction around the center axis C (not shown) of the cap unit 1C.

According to the cap unit 1C and the beverage container 100 of the present embodiment described above, the same operational effects as those of the above-described embodiments can be obtained.

In the present embodiment, the contact position between the rib (contacted portion) 72 and the groove (contact portion) 73 can be arranged on the front side of the contact position between the opposing wall portion (contacted portion) 19 and the second bearing portion (contact portion) 23 in the first embodiment. That is, since the abutment position can be disposed closer to the lid lock mechanism 50, the locked state of the lid lock mechanism 50 with respect to the lid body 20 can be more stably suppressed from being unintentionally released.

Further, although not particularly illustrated, as a modification of the present embodiment, the configuration may be such that: the cap body 10 has a groove portion (abutted portion), and the lid body 20 has a rib portion (abutting portion) which abuts against the groove portion from the rear side after the lid body 20 is displaced to the front side.

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

In the above embodiment, the biasing portion 60 that biases the lid body 20 in the opening direction around the first hinge 30 is exemplified by a torsion coil spring disposed inside the first hinge 30, but the present invention is not limited to this.

The urging portion may be constituted by the ventilation closing portion 22, for example. In this case, when the lid body 20 is in the closed state, the lower end portion of the ventilation closing portion 22 is pressed against the top wall portion 10a and elastically deformed, and the lid body 20 is urged in the opening direction around the first hinge 30 by the restoring deforming force.

Further, although not particularly shown, the biasing portion may be formed of an annular elastic member hooked on the first hinge 30 and the lid top wall portion 20a to bias the lid body 20 in the opening direction around the first hinge 30.

In the above embodiment, the lock member 52 of the cover lock mechanism 50 is rotatable about the second hinge 55, but the present invention is not limited thereto.

Fig. 10 shows a modification of the lid lock mechanism 50. In this modification, the cover lock mechanism 50 includes: a lock member 81 that is slidably movable in the front-rear direction; and an elastic member 82 capable of elastic deformation, for urging the locking member 81 to the front side. The locking member 81 and the elastic member 82 are provided to the cap body 10. The elastic member 82 is elastically deformable in the front-rear direction, and is made of, for example, rubber, an elastic body, a compression coil spring, or the like.

Further, a first claw portion (engaged portion) 83 protruding toward the front side is provided at the upper end portion of the lock member 81.

A second claw portion (locking portion) 84 that protrudes rearward is provided at a front lower end portion of the lid peripheral wall portion 20b of the lid body 20. The second claw portion (locking portion) 84 is locked to the first claw portion (locked portion) 83 from the front side.

More specifically, the cover locking mechanism 50 includes: a first claw portion (engaged portion) 83 of the locking member 81 provided on one of the cap body 10 and the lid body 20 (the cap body 10 in this modification); and a second claw portion (locking portion) 84 provided on the other of the cap body 10 and the lid body 20 (the lid body 20 in this modification), and locked to the first claw portion 83 from the front side.

Even when the cover lock mechanism 50 of the modification shown in fig. 10 is used, the same operational effects as those of the above embodiment can be obtained.

In this modification, as shown in fig. 10, it is preferable that: in the locked state in which the cover body 20 is fixed at the closed position by the cover locking mechanism 50, a dimension L1 in the front-rear direction between the abutted portion (for example, the opposing wall portion 19 of the first embodiment) and the abutting portion (for example, the second bearing portion 23 of the first embodiment) is small with respect to a locking dimension in the front-rear direction between the first pawl portion (the engaged portion) 83 and the second pawl portion (the locking portion) 84. The above-described locking dimension is a dimension in the front-rear direction of the locking portion where the lower surface of the first claw portion 83 and the upper surface of the second claw portion 84 are in contact with each other, and may be referred to as an overlapping amount.

In this case, when the lid body 20 is displaced to the front side by an impact due to dropping or the like, the abutted portions 19 first abut against the abutting portions 23, thereby suppressing the lid body 20 from being displaced to the front side beyond the above-described locking dimension. This maintains the locked state between the first claw portion 83 of the lock member 81 and the second claw portion 84 of the cover body 20, and thus the locked state of the cover body 20 can be more stably suppressed from being unintentionally released.

In the above-described embodiment, the present invention is applied to the beverage container 100 having the heat and cold retention function by the container body 2 having the vacuum heat insulation structure, but the present invention is not limited thereto. That is, the present invention can be widely applied to a cap-equipped container in which a cap unit closes an upper opening of a container body.

In the present invention, the respective configurations described in the above embodiments, modifications, and the like may be combined, and addition, omission, replacement, and other changes of the configurations may be made without departing from the spirit of the present invention. The present invention is not limited to the above-described embodiments and the like, but is defined only by the claims.
