Description

[Technical field]

[0001] The present invention relates to a cap unit and a container with a cap. [Background technology]

[0002] 2. Description of the Related Art Conventionally, there have been capped containers having a cap unit that is detachably attached to a container body that is open at the top.

[0003] Furthermore, some cap units include a cap body that closes the upper opening of the container body and has an opening at the top, a mouth-forming member that is attached around the opening of the cap body and has a liquid-passing port that communicates with the inside of the container body, and a mouth-attaching / detaching mechanism that detachably attaches the mouth-forming member to the periphery of the opening of the cap body (see, for example, Patent Document 1 below).

[0004] The mouth attachment / detachment mechanism has a locking member slidably attached to the cap body and a biasing member that biases the locking member toward one side in the sliding direction. In the mouth attachment / detachment mechanism, the mouth-forming member is released from the locked state with respect to the cap body by sliding the locking member toward the other side in the sliding direction against the biasing member. This makes it possible to remove the mouth-forming member from around the opening of the cap body. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2015-013675 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, in the conventional cap unit described above, when the cap unit is attached to the container body and the locking member is slid in error, the locked state of the mouth-forming member relative to the cap body is released, causing the cap body to come off from the container body.

[0007] In other words, conventional attachment / detachment mechanisms are not provided with a locking mechanism for preventing the locking member from sliding in the event of an erroneous sliding operation of the locking member described above, and are not necessarily easy to use.

[0008] On the other hand, adding the above-mentioned locking mechanism would result in an increase in the number of parts, a more complicated structure, and an increase in the size of the product.

[0009] The present invention has been proposed in consideration of the above-mentioned conventional circumstances, and aims to provide a cap unit in a mouth attachment / detachment mechanism that has a space-saving and simple structure while being capable of preventing the locking member from sliding in the event of erroneous sliding operation of the locking member, and a capped container that is equipped with such a cap unit, thereby enabling further improvement in usability.

[0015] As shown in Figs. 1 to 6, a capped container 100 of this embodiment includes a cap unit 1 of this embodiment and a container body 2 to which the cap unit 1 is detachably attached.

[0016] The capped container 100 is a beverage container capable of keeping a beverage (liquid) contained in the container body 2 cool (or warm) by the container body 2 having a vacuum insulation structure.

[0017] Specifically, the container body 2 has a bottomed cylindrical outer container 3 and an inner container 4 made of, for example, stainless steel, and is configured as a double-structure container in which the inner container 4 is housed inside the outer container 3 and the periphery of their mouths is joined together.

[0018] In addition, a vacuum insulation layer 5 is provided between the outer container 3 and the inner container 4. The vacuum insulation layer 5 can be formed, for example, by blocking a vent hole provided on the bottom surface of the outer container 3 in a chamber that is depressurized (evacuated) to a high vacuum.

[0019] The container body 2 has a substantially circular bottom 2a, a body 2b that stands up in a substantially cylindrical shape from the outer periphery of the bottom 2a, and a substantially cylindrical mouth neck 2c that is tapered in diameter on the upper side of the body 2b.

[0020] The upper end of the mouth / neck portion 2c opens in a circular shape as the upper opening 2d of the container body 2. The inner circumferential surface of the mouth / neck portion 2c (on the upper side of the body portion 2b) is narrower in diameter than the inner circumferential surface of the body portion 2b. Furthermore, a ring-shaped protruding portion 6 is provided protruding around the entire circumference near the lower side of the inner circumferential surface of the mouth / neck portion 2c (below the narrowed portion on the upper side of the body portion 2b).

[0021] A shoulder member 7 is attached around the entire circumference below the mouth and neck portion 2c on the upper side of the body portion 2b. The shoulder member 7 is made of, for example, a cylindrical resin member, and is fitted around the entire circumference into a stepped portion 2e whose diameter is reduced on the upper side of the body portion 2b so as to be approximately flush with the outer circumferential surface of the body portion 2b.

[0022] Although the capped container 100 of this embodiment has a generally cylindrical external shape as a whole, the external shape of the capped container 100 is not particularly limited and can be modified as appropriate according to the size, design, etc. In addition, the outer circumferential surface of the container body 2 may be painted, printed, or the like.

[0023] The cap unit 1 of this embodiment comprises a cap body 8 that closes the upper opening 2d of the above-mentioned container body 2, a lid body 10 that is rotatably attached to the cap body 8 via a first hinge portion 9, and a handle member 12 that is rotatably attached to the cap body 8 via a second hinge portion 11.

[0024] In the following description, the side where the lid body 10 is attached to the cap body 8 via the first hinge portion 9 will be referred to as the "rear side (back side)" of the cap unit 1 (capped container 100), and the opposite side will be referred to as the "front side (front surface side)" of the cap unit 1 (capped container 100), and the direction connecting these will be referred to as the front-to-rear direction.

[0025] 1, the side where the lid 10 is located relative to the container body 2 is referred to as the "upper side", the direction where the container body 2 is located relative to the lid 10 is referred to as the "lower side", and the direction connecting these will be referred to as the up-down direction. The direction perpendicular to the up-down direction will be referred to as the radial direction, and the direction perpendicular to the front-rear direction of the radial direction will be referred to as the left-right direction.

[0026] As shown in Figs. 2 to 6, the cap body 8 has an outer cylinder member 13 and a mouth-forming member 14 made of, for example, a heat-resistant resin.

[0027] The outer tube member 13 has a peripheral wall portion 13a formed in an approximately cylindrical shape so as to be continuous with the trunk portion 2b of the container body 2, and an upper wall portion 13c in which an opening portion 13b, which is a through hole having a smaller diameter than the peripheral wall portion 13a, is formed at the upper part of the peripheral wall portion 13a.

[0028] The outer tube member 13 (cap body 8) is detachably attached by screwing to the mouth / neck portion 2c of the container body 2. For this purpose, a first male screw portion 15 is provided on the outer peripheral surface of the mouth / neck portion 2c (on the upper side of the body portion 2b). On the other hand, a first female screw portion 16 that screws into the first male screw portion 15 is provided on the inner peripheral surface of the peripheral wall portion 13a of the outer tube member 13 (cap body 8).

[0029] As shown in Figures 4 to 8, the mouth forming member 14 has an upper mouth forming portion 14a that forms the upper side of the opening 13b of the outer tube member 13, and a lower mouth forming portion 14b that forms the lower side of the opening 13b of the outer tube member 13.

[0030] The upper mouth forming portion 14a has a nozzle portion 17 that protrudes upward in a substantially cylindrical shape. A circular liquid passage port 17a that communicates with the inside of the container body 2 and serves as a drinking spout or a pouring spout is provided at the tip of the nozzle portion 17.

[0031] In other words, when the cap body 8 is attached to the mouth neck portion 2c of the container body 2, it closes the upper opening 2d of the container body 2 and connects the inside and outside of the container body 2 via the nozzle portion 17 (liquid passage hole 17a).

[0032] The lower mouth forming portion 14b is a portion that is fitted into the inside of the container body 2 from the upper opening 2d of the container body 2, and is provided protruding in a substantially cylindrical shape from the lower side of the upper mouth forming portion 14a.

[0033] The port-forming member 14 is detachably attached around the opening 13b of the outer tube member 13 via a port attachment / detachment mechanism 18 shown in FIGS.

[0034] Specifically, this mouth attachment / detachment mechanism 18 has a locking member 19 attached to the outer tube member 13 (cap body 8) so as to be freely slidable in the front-to-rear direction, a biasing member 20 that biases the locking member 19 toward one side (front side) in the sliding direction, a first engaging portion 21 located on the opposite side (front side) of the side facing the locking member 19 of the mouth forming member 14, a second engaging portion 22 located on the side facing the locking member 19 of the mouth forming member 14 (rear side), a first engaged portion 23 located on the front side around the opening 13b of the outer tube member 13 (cap body 8), and a second engaged portion 24 located on one side (front side) in the sliding direction of the locking member 19.

[0035] As shown in Figures 7 to 9 and Figures 10(A) and (B), the locking member 19 is made of, for example, a heat-resistant resin, and has an operating portion 19a, a cover portion 19b, a spring receiving portion 19c, a pair of fitting portions 19d, and a pair of anti-removal portions 19e.

[0036] The operating portion 19a is located on the upper surface side of the locking member 19 and has a recessed shape to facilitate sliding operation of the locking member 19 with a finger. Note that the shape of the operating portion 19a is not limited to this and can be modified as appropriate.

[0037] On the other hand, a cutout recess 13d for accommodating a lock member 19 is provided on the upper surface (upper wall portion 13c of the outer cylinder member 13) of the cap body 8.

[0038] The cutout recess 13d is located on the side (rear side of the cap body 8) where the first hinge portion 9 is located around the opening 13b of the upper wall portion 13c (cap body 8), and is cut out along the sliding direction of the locking member 19 (the front-to-rear direction of the cap body 8).

[0039] The lock member 19 is located inside the notched recess 13d, and has an operating portion 19a facing the upper surface of the cap body 8.

[0040] Further, on the upper surface (upper wall portion 13c of the outer tube member 13) of the cap body 8, a step portion 13e is provided by recessing the periphery of the opening 13b of the upper wall portion 13c (cap body 8) toward the opposite side (front side of the cap body 8) from the first hinge portion 9. As a result, the cutout recess 13d is provided so as to cut out a part of the step portion 13e (rear side of the cap body 8).

[0041] In the mouth attachment / detachment mechanism 18, the operating portion 19a of the locking member 19 facing outward from the notched recess 13d is provided so as to be inclined upward toward the rear side of the cap body 8 along the inclination of the step portion 13e. This makes it easy to slide the operating portion 19a of the locking member 19 facing outward from the notched recess 13d with a finger toward the other side (rear side) in the sliding direction.

[0042] 7, the upper surface of the locking member 19 is substantially flush with the upper surface of the cap body 8, which is made up of the upper wall portion 13c and the step portion 13e of the outer tube member 13. This allows the cap unit 1 to have a space-saving and simple structure without interference between the cover body 10 and the locking member 19, even when the cover body 10 is in the closed position. This also makes it easier to operate the operating portion 19a of the locking member 19, and allows for an aesthetically unified appearance.

[0043] The cover portion 19b is located on the underside of the locking member 19 and is exposed on the underside so as to cover the inner underside of the cap body 8 including the urging member 20 (the underside of the upper wall portion 13c), and is formed in a substantially rectangular flat plate shape.

[0044] The spring receiving portion 19c is configured by a protrusion that protrudes rearward from the center of the rear side of the operating portion 19a.

[0045] The pair of fitting portions 19d are located on both left and right sides of the locking member 19 and are configured by guide grooves formed in a concave shape on the inside in the left and right direction between the operating portion 19a and the cover portion 19b in the front-rear direction.

[0046] The pair of anti-slip portions 19e are located on both sides of the spring receiving portion 19c in the left-right direction, protrude rearward from the back side of the operating portion 19a, and are configured as hook portions whose tips protrude outward.

[0047] On the other hand, as shown in Figures 7 to 9, 11 and 12, the cap body 8 has a spring receiving portion 25a, a pair of guide portions 25b, and a pair of stopper portions 25c on the inner lower surface of the outer tube member 13 (the lower surface of the upper wall portion 13c).

[0048] The spring receiving portion 25a is located at the tip side of the portion that protrudes forward from the rear center of the cutout recess 13d, and is composed of a pair of protrusions that protrude forward from both the left and right sides.

[0049] The pair of guide portions 25b are positioned on both left and right sides of the cutout recess 13d, and are configured by guide protrusions that extend in the front-rear direction from the lower end of the cutout recess 13d and protrude inward in the left-right direction.

[0050] The lock member 19 is attached so as to be slidable in the front-rear direction inside the cutout recess 13d by fitting the pair of guide portions 25b into the pair of fitting portions 19d.

[0051] The pair of stopper portions 25c are positioned on both left and right sides of the cutout recess 13d and are constituted by claw portions protruding inward from the rear side surfaces of the cutout recess 13d.

[0052] The lock member 19 is prevented from coming off from inside the cutout recess 13d by a pair of retaining portions 19e abutting against a pair of stopper portions 25c on one side (front side) in the sliding direction.

[0053] As shown in Figures 11 and 12, the biasing member 20 is made of, for example, a coil spring, and is disposed between one spring receiving portion 25a on the outer tube member 13 (cap body 8) side and the other spring receiving portion 19c on the locking member 19 side, and constantly biases the locking member 19 to one side (the front side).

[0054] The locking member 19 is biased to one side (front side) in the sliding direction by the biasing member 20, so that a pair of anti-slip portions 19e abut against a pair of stopper portions 25c, and is prevented from slipping out toward the front side from the inside of the cutout recess 13d.

[0055] On the other hand, by pushing the lock member 19 against the bias of the biasing member 20, it can be slid toward the other side (rear side) in the sliding direction, that is, toward the first hinge portion 9 side.

[0056] Incidentally, for the biasing member 20, instead of a spring member such as the coil spring described above, an elastic member such as rubber or elastomer may be used.

[0057] As shown in Figures 13 to 15, the first engagement portion 21 is located at the boundary between the upper mouth forming portion 14a and the lower mouth forming portion 14b of the mouth forming member 14, and is composed of a claw portion protruding forward from the front side of the mouth forming member 14.

[0058] The second engagement portion 22 is located at the boundary between the upper mouth forming portion 14a and the lower mouth forming portion 14b of the mouth forming member 14, and is composed of a claw portion protruding rearward from the rear side of the mouth forming member 14.

[0059] The first locked portion 23 is configured by a step portion formed by recessing a part of the front side along the opening 13b of the upper wall portion 13c (step portion 13e).

[0060] The second locked portion 24 is configured by a claw portion that protrudes forward from below the front operating portion 19a of the locking member 19.

[0061] In the mouth attachment / detachment mechanism 18, first, as shown in Figure 15, the upper mouth forming portion 14a of the mouth forming member 14 is fitted from the lower side into the inside of the opening 13b of the outer tube member 13 (cap body 8), while engaging the first engaging portion 21 with the first engaged portion 23.

[0062] Next, by pushing the rear side of the opening forming member 14 upward, the second engaging portion 22 moves upward while pushing the locking member 19 against the bias of the biasing member 20 toward the other side (rear side) in the sliding direction.

[0063] 13, the locking member 19 slides to a locking position on one side (front side) in the sliding direction due to the biasing force of the biasing member 20, thereby locking the second locking portion 22 to the second locked portion 24. This makes it possible to attach the mouth-forming member 14 to the periphery of the opening 13b of the outer tube member 13 (cap body 8).

[0064] On the other hand, in the mouth attachment / detachment mechanism 18, from the state shown in Figure 13, as shown in Figure 14, the locking member 19 is slid from the locked position on one side (front side) of the sliding direction toward the unlocked position on the other side (rear side) of the sliding direction against the force of the biasing member 20.

[0065] This allows the mouth-forming member 14 to be released from its locked state relative to the outer tube member 13 (cap body 8), as shown in Figure 15, and makes it possible to remove the mouth-forming member 14 downward from around the opening 13b of the outer tube member 13 (cap body 8).

[0066] As shown in Figs. 4 and 5, a watertight packing 26 is detachably attached to the port forming member 14.

[0067] The waterproof gasket 26 is a ring-shaped sealing member for sealing the space between the protrusion 6 (container body 2) and the mouth-forming member 14 (cap body 8), and is made of an elastic material such as a heat-resistant rubber such as silicone rubber or an elastomer.

[0068] The watertight gasket 26 is fitted onto the outer periphery of the lower flange portion 14c provided on the outer periphery of the lower end side of the lower port forming portion 14b (port forming member 14).

[0069] Further, two elastic flange portions 26a are provided on the outer circumferential surface of the watertight packing 26 so as to protrude in the radially expanding direction over the entire circumference.

[0070] When the cap unit 1 is attached to the container body 2 so as to block the upper opening 2d, the water-stopping gasket 26 has its lower mouth forming portion 14b (mouth forming member 14) fitted inside the container body 2, and the elastic flange portion 26a elastically deforms to fit tightly against the protrusion portion 6 around its entire circumference.

[0071] This makes it possible to seal (watertightly seal) the gap between the protruding portion 6 (container body 2) and the mouth-forming member 14 (cap body 8) via the waterproof packing .

[0072] On the other hand, the watertight gasket 26 can be removed from the lower flange portion 14c (the opening forming member 14) by elastically deforming (pulling and stretching) the watertight gasket 26 itself.

[0073] This allows the watertight gasket 26 and the port-forming member 14 to be washed separately, and the space between the watertight gasket 26 and the port-forming member 14 can be kept hygienic.

[0074] The watertight packing 26 is not necessarily limited to the shape described above, and for example, the number of elastic flange portions 26a is not limited to the above-mentioned two, but can be one or three or more. The watertight packing 26 is not necessarily limited to a configuration provided with the above-mentioned elastic flange portions 26a, and the shape, etc. can be appropriately changed.

[0075] The watertight gasket 26 may be integrally molded so as not to be detachable from the opening-forming member 14. In this case, it is possible to prevent liquid or dirt from entering between the watertight gasket 26 and the opening-forming member 14, and to maintain hygiene.

[0076] As shown in Figs. 1 to 5, the lid 10 has a rotating member 27 and a cap member 28 made of, for example, a heat-resistant resin.

[0077] The pivoting member 27 has a base end attached to the first hinge portion 9 so as to be freely rotatable, and has a circular ring-shaped ring portion 27a at its tip end, the portion of the inner circumferential surface of which (in this embodiment, two portions in the front-to-rear direction) is shaped to have a concave cross section.

[0078] The cap member 28 has a peripheral wall portion 28a formed in a substantially cylindrical shape, a top wall portion 28b covering the upper portion of the peripheral wall portion 28a, and a convex ring portion 28c intermittently protruding from the outer periphery of the lower end side of the peripheral wall portion 28a all around. The cap member 28 is attached so as to be rotatable about its central axis by being locked in a state in which the convex ring portion 28c is fitted inside the ring portion 27a.

[0079] In addition, since the vertical width of the convex shape of convex ring portion 28c is smaller than the vertical width of the cross-sectional concave shape of ring portion 27a, cap member 28 can slide vertically relative to rotating member 27. Furthermore, cap member 28 can be moved so that the lower end side is slightly tilted in the circumferential direction relative to ring portion 27a (rotating member 27).

[0080] The cap member 28 is detachably attached to the nozzle portion 17 by screwing, thereby opening and closing the liquid passage port 17a of the nozzle portion 17. For this purpose, a second female screw portion 29 is provided on the inner peripheral surface of the peripheral wall portion 28a (cap member 28). On the other hand, a second male screw portion 30 that screws into the second female screw portion 29 is provided on the outer peripheral surface of the nozzle portion 17.

[0081] As described above, the cap member 28 can slide up and down relative to the rotating member 27, and further, the lower end side of the cap member 28 can be moved so as to tilt slightly in the circumferential direction. Therefore, when the lid 10 is in the closed position and the second female screw portion 29 and the second male screw portion 30 are screwed together, the cap member 28 rotates in a horizontal position, and the screwing can be performed smoothly without worrying about the rotating member 27.

[0082] In the cap unit 1 of this embodiment, as shown in Figures 1 and 2, when the cap member 28 (lid body 10) closes the liquid passage port 17a of the nozzle portion 17, the rotating member 27 covers the operating portion 19a of the locking member 19.

[0083] For this reason, when the cap member 28 (lid body 10) closes the liquid passage port 17a of the nozzle portion 17, the lock member 19 cannot be operated and the port-forming member 14 will not come off from the outer tube member 13. This prevents the port-forming member 14 from coming off unintentionally, providing peace of mind.

[0084] As shown in FIGS. 1 to 5, 16, and 17(A) and (B), a lid packing 31 is detachably attached to the lid 10. As shown in FIG.

[0085] The lid gasket 31 is a plug-shaped sealing member for sealing the tip side (fluid passage port 17a) of the nozzle portion 17. The lid gasket 31 is made of an elastic member, and the same material as the water stop gasket 26 can be used for this elastic member.

[0086] The lid gasket 31 has a substantially cylindrical shaft portion 31a, a plug portion 31b protruding in the radially expanding direction from the lower end of the shaft portion 31a around the entire circumference, and a protrusion 31c protruding downward from the center of the plug portion 31b.

[0087] On the other hand, the cap member 28 (lid body 10) has a hole 28d penetrating the center of the top wall 28b. A circular protrusion 28e is provided on the lower end side of the hole 28d so as to protrude downward from the top wall 28b around the entire periphery of the hole 28d.

[0088] The shaft portion 31a has an increased diameter around the entire circumference at its end, and has a reduced diameter portion 28f, the smallest diameter portion, midway on the upper side of the hole 28d.

[0089] The lid gasket 31 is attached to the inner underside of the cap member 28 (the underside of the top wall portion 28b) by inserting the shaft portion 31a into this hole portion 28d from below, so that the enlarged portion of the shaft portion 31a fits into the reduced diameter portion 28f of the hole portion 28d.

[0090] In order to insert the shaft portion 31a into the hole 28d, the shaft portion 31a needs to have a certain degree of rigidity. For this reason, it is preferable that the lid gasket 31 is a solid member with no hollow space inside the shaft portion 31a. On the other hand, the lid gasket 31 can be made lighter by reducing the amount of material used, by making the inside of the shaft portion 31a hollow. In this case, it is necessary to select a material with an appropriate hardness to ensure the rigidity.

[0091] In addition, because the lid packing 31 is attached to the inner underside of the cap member 28 through the hole 28d, it is possible to visually confirm from the outside that the top surface of the shaft portion 31a is approximately flush with the top wall portion 28b even when the cap member 28 (lid body 10) is blocking the liquid passage port 17a of the nozzle portion 17. This makes it easy to confirm that the lid packing 31 has not been left attached.

[0092] The protruding portion 31c can enter the inside of the nozzle portion 17 from the liquid passage port 17a, and protrudes downward to an extent that it can be held with fingers. The protruding portion 31c is formed in a flat plate shape so that it can be easily held with fingers.

[0093] Furthermore, at the tip (lower end) of protruding portion 31c, the long side of the flat plate shape is provided to protrude in the radial direction as flange portion 31d. Flange portion 31d functions as a slip prevention and finger grip when protruding portion 31c is pinched with fingers.

[0094] In addition, the lower end side of the protrusion 31c is located above the lower end of the cap member 28 and below the central axis of the first hinge part 9. If the protrusion 31c is too long, it becomes difficult to introduce it into the nozzle part 17 when the lid body 10 is in the closed position, and conversely, if it is too short, it becomes difficult to grasp it.

[0095] In the cap unit 1 of this embodiment, when the cap member 28 (lid body 10) closes the liquid passage port 17a of the nozzle portion 17, the plug portion 31b is in close contact with the periphery of the tip side of the nozzle portion 17.

[0096] Here, the plug portion 31b has a hemispherical shape with a downward convex shape, and has an upper rib 31e on its upper side that is concentrically provided upward. When the lid packing 31 is attached to the inner lower surface of the cap member 28 through the hole 28d, the circular convex portion 28e is inserted into the valley between the shaft portion 31a and the upper rib 31e.

[0097] Therefore, when plug portion 31b comes into close contact with the periphery of the tip side of nozzle portion 17, plug portion 31b is pressed down from above by circular protrusion portion 28e, and the upper end of upper rib 31e abuts against the lower surface side of top wall portion 28b.

[0098] This makes it difficult for the center side (projection 31c side) of plug portion 31b to elastically deform upward, and only the outer periphery side of plug portion 31b that abuts against the tip side of nozzle portion 17 can elastically deform and bend.

[0099] Therefore, the effective deflection length of plug portion 31b is reduced and plug portion 31b is pressed from above by circular protrusion 28e and from below by the tip side of nozzle portion 17, so that plug portion 31b adheres more firmly to the periphery of the tip side of nozzle portion 17.

[0100] This makes it possible to reliably seal the tip side (fluid passage port 17a) of the nozzle portion 17 via the lid packing 31.

[0101] On the other hand, in the cap unit 1 of this embodiment, the lid gasket 31 can be easily removed from the inside of the cap member 28 (lid body 10) by pinching and pulling downward the protruding portion 31c.

[0102] Furthermore, in the cap unit 1 of this embodiment, the lid gasket 31 can be easily attached to the inner underside (underside of the top wall portion 28b) of the cap member 28 (lid body 10) by pinching the protruding portion 31c of the above-mentioned lid gasket 31 and pushing it upward from the underside of the cap member 28.

[0103] In addition, since the lid gasket 31 removed from the cap member 28 (lid body 10) can be washed separately from the cap member 28 (lid body 10), it is possible to keep the area between the lid gasket 31 and the cap member 28 (lid body 10) hygienic.

[0104] As shown in Figures 1 to 3, the handle member 12 consists of a ring-shaped member with a portion open, and is rotatably attached to the outer tube member 13 (cap body 8) via a second hinge portion 11 provided on the rear side surface (circumferential wall portion 13a) of the outer tube member 13.

[0105] As a result, the capped container 100 including the cap unit 1 of this embodiment can be carried while gripping the handle member 12.

[0106] In a capped container 100 having the cap unit 1 of this embodiment having the above-mentioned configuration, the mouth attachment / detachment mechanism 18 will be described in a state in which the cap body 8 is attached to the above-mentioned container body 2 and the cap member 28 (lid body 10) opens the liquid passage port 17a of the nozzle portion 17.

[0107] 6, when the locking member 19 (mouth attachment / detachment mechanism 18) is slid toward the unlocked position on the other side (rear side) in the sliding direction with the cap body 8 attached to the container body 2, the rear end of the cover portion 19b, which is a part of the locking member 19, comes into contact with the inner surface of the mouth / neck portion 2c of the container body 2. At this time, the rear end of the cover portion 19b comes into contact with the inner surface of the mouth / neck portion 2c of the container body 2 before the locked state between the second locking portion 22 and the second locked portion 24 is released.

[0108] This makes it possible to prevent the locking member 19 from sliding in the event of an erroneous sliding operation of the locking member 19, while preventing the locked state of the mouth-forming member 14 relative to the outer tube member 13 (cap body 8) from being released, and to prevent the mouth-forming member 14 from coming off.

[0109] Furthermore, in the event that the capped container 100 is dropped, for example, it is possible to prevent the mouth-forming member 14 from coming off the outer tube member 13 (cap body 8) due to an erroneous sliding operation of the locking member 19 caused by the impact of the drop.

[0110] Furthermore, in the cap unit 1 of this embodiment, there is no need to provide a separate locking mechanism to prevent the above-mentioned locking member 19 from sliding, so the mouth attachment / detachment mechanism 18 can be made space-saving and have a simple structure without increasing the number of parts.

[0111] In addition, since the cover portion 19b is exposed on the underside so as to cover the inner underside of the cap body 8 (the underside of the upper wall portion 13c), the internal structure of the mouth attachment / detachment mechanism 18 including the biasing member 20 cannot be seen from the outside, resulting in a good appearance.

[0112] As described above, in the capped container 100 equipped with the cap unit 1 of this embodiment, the above-mentioned mouth attachment / detachment mechanism 18 has a simple structure, and is capable of preventing the locking member 19 from sliding in the event of an erroneous sliding operation of the locking member 19, thereby making it possible to further improve usability.

[0113] The present invention is not necessarily limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0114] For example, in the above embodiment, a cap unit 1 is exemplified that has a mouth forming member 14 provided with a nozzle portion 17 that forms the above-mentioned liquid passage port 17a, but the mouth forming member 14 is not limited to such a configuration and may be configured, for example, such that a liquid passage port is provided on the bottom surface of the mouth forming member that forms the drinking spout or pouring spout.

[0115] In addition, in the above embodiment, a cap unit 1 is exemplified in which the cap member 28 (lid body 10) is detachably attached to the above-mentioned nozzle portion 17 by screwing, but the configuration is not limited to this. For example, the configuration may be such that the lid body that opens and closes the liquid passage port is rotatably attached to the cap body via a hinge portion and is equipped with a lid locking mechanism that fixes the lid body to the cap body.

[0116] In the above embodiment, an example is shown of the application of the present invention to a beverage container having a heat / cold insulation function provided by the container body 2 having the above-mentioned vacuum insulation structure, but the present invention can be widely applied to a capped container having a container body and a cap unit that can be freely attached and detached to the container body.
