Description

TECHNICAL FIELD

[0001] The present application relates to a cap unit and a capped container. BACKGROUND

[0002] In the past, there has been a capped container provided with a cap unit that is detachably attached to a container main body of an upper opening.

[0003] Further, in the cap unit, there is a cap unit provided with a cap main body that closes an upper opening portion of a container main body and is provided with a liquid passage that communicates with the inside of the container main body, and a cap that is rotatably attached to the cap main body by a hinge portion and is provided with a plug portion that closes the liquid passage of the cap main body (for example, refer to Patent Literature 1 below).

[0004] Specifically, in Patent Literature 1 below, a plug body of a beverage container is disclosed, which is detachably attached to an upper end opening of a container main body, has a drinking port portion that opens upward, and has a flow port in the inner bottom surface of the drinking port portion that allows a beverage in the container main body to flow out, and is provided with a single-leaf-shaped cap that closes the flow port, and a lock mechanism that closes the cap, an upper end edge of the drinking port portion is circular and horizontally formed in plan view, an inner surface of the drinking port portion is composed of a curved surface that is curved in a bowl shape, the flow port is composed of a hole that has a circular outline in plan view, a diameter of the flow port is 0.4 times or more of an inner diameter of the upper end edge of the drinking port portion, and a height from the upper end edge of the drinking port portion to the flow port is 0.5 times or more of the inner diameter of the upper end edge of the drinking port portion.

[0005] Patent Literature 1: Japanese Patent Application Publication No. 2021-195165

[0006] However, in the above-described conventional cap unit, the liquid passage is formed in the bottom of the mouth forming portion of the cap main body that is formed in a recessed shape, and when the cap is closed, the plug portion is inserted into the inside of the mouth forming portion while the liquid passage is closed by the plug gasket that is in close contact with the bottom surface of the inside of the mouth forming portion.

[0007] In the capped container provided with such a cap unit, when a beverage in the container main body is drunk, the container main body is tilted to the side opposite to the hinge portion while the beverage flowing out from the liquid passage to the inside of the mouth forming portion is drunk.

[0008] In this case, depending on the angle and speed at which the container main body is tilted, the beverage is sometimes violently sprayed from the liquid passage to the inside of the mouth forming portion, and the beverage flowing out from the liquid passage pulsates. In particular, when a warm beverage is drunk, it is necessary to tilt the container main body little by little while taking care not to violently spray the beverage in the container main body from the liquid passage.

[0009] In addition, if the lid is closed after drinking the beverage in the container body, the beverage remaining on the inner side of the mouth forming portion does not return to the container body from the liquid passage, but remains directly between the mouth forming portion and the plug portion. Therefore, in the case where the beverage remaining on the inner side of the mouth forming portion splashes or the beverage is colored when the lid is opened, the beverage adhering to the inner side of the mouth forming portion sometimes appears like dirt

[0010] Further, when the cap unit is cleaned, the residual liquid accumulated on the inner and outer sides of the mouth forming portion is difficult to dry, and thus a configuration that is easy to control water and dry is desired from the viewpoint of hygiene. SUMMARY

[0011] The present application has been made in view of such conventional circumstances, and has an object to provide a cap unit that is easy to drink a beverage flowing from a liquid passage to an inner side of a mouth forming portion and that is capable of improving cleanability while preventing the beverage adhering to the mouth forming portion from remaining, and a container with a cap that is capable of further improving convenience in use by having such a cap unit.

[0070] The capped container 100 is a beverage container that can keep the beverage (liquid) contained in the container body 2 cold (or warm) through the container body 2 having a vacuum insulation structure.

[0071] Specifically, such as Figures 1 to 7As shown, the container body 2 is composed of a double-layered container having, for example, a bottomed cylindrical outer container 3 composed of stainless steel or the like and an inner container 4, and is formed by joining the periphery of the mouth of each other in a state where the inner container 4 is housed inside the outer container 3.

[0072] Further, a vacuum heat insulating layer 5 is provided between the outer container 3 and the inner container 4. The vacuum heat insulating layer 5 can be formed, for example, by plugging an exhaust hole provided on the bottom surface of the outer container 3 in a state where it is reduced in pressure (vacuumed) to a high vacuum.

[0073] The container body 2 has a substantially circular bottom portion 2a, a cylindrical portion 2b that stands up in a substantially cylindrical shape from the outer periphery of the bottom portion 2a, and a substantially cylindrical neck portion 2c that is reduced in diameter on the upper side of the cylindrical portion 2b.

[0074] The upper portion of the neck portion 2c is opened in a circular shape as an upper opening portion 2d of the container body 2. Further, the inner peripheral surface of the inner container 4 of the neck portion 2c (the upper side of the cylindrical portion 2b) of the container body 2 is reduced in diameter from the inner peripheral surface of the cylindrical portion 2b. Further, on the inner peripheral surface of the inner container 4 of the neck portion 2c, a ring-shaped protruding portion 6 is provided so as to protrude inwardly throughout the entire circumference of the container body 2.

[0075] Further, the container body 2 has a bottom member 7a that is installed on the bottom portion 2a side throughout the entire circumference, and a shoulder member 7b that is installed on the upper side of the cylindrical portion 2b throughout the entire circumference.

[0076] The bottom member 7a is composed of an elastic resin member that is formed in a bottomed cylindrical shape as a whole, and is installed by being embedded in a state of covering the entire surface of the bottom portion 2a of the container body 2. The shoulder member 7b is composed of a resin member that is formed in a substantially cylindrical shape as a whole, and is installed by being embedded in a state of being substantially flush with the outer peripheral surface of the cylindrical portion 2b throughout the entire circumference of the neck portion 2c on the upper side of the cylindrical portion 2b, below the step portion 2e to which the plate thickness of the shoulder member 7b is reduced.

[0077] Further, the cap-equipped container 100 of the present embodiment has a substantially cylindrical appearance shape as a whole, but the appearance shape of the cap-equipped container 100 is not particularly limited, and can be appropriately changed according to the size, the design, and the like. Further, painting, printing, or the like can be performed on the outer peripheral surface of the container body 2.

[0078] As shown, the cap-equipped container 100 of the present embodiment has a substantially cylindrical appearance shape as a whole, but the appearance shape of the cap-equipped container 100 is not particularly limited, and can be appropriately changed according to the size, the design, and the like. Further, painting, printing, or the like can be performed on the outer peripheral surface of the container body 2. Figures 1 to 7 As shown, the cap unit 1 of the present embodiment is provided with a cap body 8 that closes the upper opening portion 2d of the above-described container body 2, a lid 10 that is rotatably installed to the cap body 8 by means of a first hinge portion 9, and a handle member 12 that is rotatably installed to the cap body 8 by means of a second hinge portion 11.

[0079] Furthermore, in the following description, the side on which the cap 10 is mounted relative 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 face)" of the cap unit 1 (capped container 100), with the direction connecting them described as the front-rear direction. Additionally, the side on which the cap 10 is located relative to the container body 2 will be referred to as the "upper side," and the direction on which the container body 2 is located relative to the cap 10 will be referred to as the "lower side," with the direction connecting them described as the up-down direction. Furthermore, the direction orthogonal to the up-down direction will be referred to as the radial direction, and the radial direction orthogonal to the front-rear direction will be described as the left-right direction.

[0080] The cap body 8 has an outer cylinder component 13 that becomes an outer cylinder portion and an orifice forming component 14 that becomes an orifice forming portion, and has a structure in which these outer cylinder components 13 and orifice forming components 14 are integrally assembled.

[0081] The outer cylinder component 13 is made of, for example, heat-resistant resin and has: a peripheral wall portion 13a, which is formed in a generally cylindrical shape in a manner continuous with the cylindrical portion 2b of the container body 2; and an upper wall portion 13c, on the upper part of the peripheral wall portion 13a, an opening portion 13b that is narrower than the peripheral wall portion 13a is formed.

[0082] like Figures 2 to 15 As shown, the opening forming member 14 is made of, for example, a heat-resistant resin and has: a generally cylindrical upper opening forming portion 14a located above the opening portion 13b of the outer cylinder member 13; a generally cylindrical lower opening forming portion 14b continuous with the upper opening forming portion 14a and located below the opening portion 13b of the outer cylinder member 13; and a generally circular bottom wall portion 14c that closes the bottom of the lower opening forming portion 14b.

[0083] In the cap body 8, with the opening forming member 14 penetrating the opening 13b of the outer cylinder member 13, the outer periphery of the opening forming member 14 is fitted with the inner periphery of the opening 13b of the outer cylinder member 13, thereby assembling the outer cylinder member 13 and the opening forming member 14 into one unit. Furthermore, the cap body 8 is not limited to the aforementioned configuration where the outer cylinder member 13 and the opening forming member 14 are assembled into one unit; it can also be configured such that the opening forming member 14 is detachably mounted on the inner periphery of the opening 13b of the outer cylinder member 13.

[0084] An inlet 15 is provided on the upper opening portion 14a for easy pouring or drinking of beverages from the container body 2. The inlet 15 is provided as an obliquely cut cylindrical part protruding upward from the side of the upper opening portion 14a opposite to the first hinge portion 9 (the front side of the opening portion 14) of the outer cylinder portion 13.

[0085] A liquid passage 16 through which the beverage in the container body 2 flows is provided in the bottom of the mouth forming member 14 so as to penetrate the bottom wall portion 14c in the up-and-down direction. In addition, an air inlet 17 through which outside air is introduced into the inside of the container body 2 is provided in the bottom of the mouth forming member 14 so as to penetrate a corner portion constituted by the bottom wall portion 14c and the inner side surface of the lower side mouth forming portion 14b in the up-and-down direction.

[0086] As shown in Figs. 1 and 2, the liquid passage 16 is located on the front side of the bottom wall portion 14c and is provided so as to open in a substantially semicircular shape in plan view. That is, the liquid passage 16 is formed so as to have a shallow V-letter shape in which the opening edge portion 16a on the rear side thereof spreads in the left-and-right direction in plan view, and has an outer shape in which the opening edge portion 16b on the front side thereof from the opening edge portion 16a on the rear side is formed in a circular arc shape. Figure 9 Figure 13 Figure 15 As shown in Figs. 1 and 2, the liquid passage 16 is located on the front side of the bottom wall portion 14c and is provided so as to open in a substantially semicircular shape in plan view. That is, the liquid passage 16 is formed so as to have a shallow V-letter shape in which the opening edge portion 16a on the rear side thereof spreads in the left-and-right direction in plan view, and has an outer shape in which the opening edge portion 16b on the front side thereof from the opening edge portion 16a on the rear side is formed in a circular arc shape.

[0087] In addition, the mouth forming member 14 has a eave portion 18 including a vertical wall 18a which stands up linearly from the inner side bottom surface of the bottom wall portion 14c in a manner so as to substantially follow the opening edge portion 16a on the rear side of the liquid passage 16, and a horizontal wall 18b which projects forward along the upper surface of the liquid passage 16 from the front end (upper end) of the vertical wall 18a in a manner so as to cover the upper surface of the liquid passage 16.

[0088] The horizontal wall 18b of the eave portion 18 has an outer shape which follows the outer shape of the opening edge portions 16a, 16b of the liquid passage 16 in plan view. That is, as shown in Figs. 1 and 2, the horizontal wall 18b has a substantially uniform outer shape which is slightly smaller than the liquid passage 16 in plan view, and is provided so as to oppose the upper portion of the liquid passage 16. Thus, the liquid passage 16 and the eave portion 18 are open to each other in a slit-like manner along the periphery of the opening edge portion 16b on the front side at a position on the front side from the vertical wall 18a by an amount of the height of the vertical wall 18a. Figure 9

[0089] In the cap unit 1 of the present embodiment, in a state in which the cap body 8 is attached to the container body 2, the bottom surface E1 of the inner side bottom surface of the bottom wall portion 14c on the rear side from the standing position of the eave portion 18 is located at a position on the upper side from the liquid passage 16, and the bottom surfaces E1 on both sides of a ridge line T which extends toward the rear side from the central portion of the standing position of the eave portion 18 are provided with slopes which face each other in opposite directions toward the liquid passage 16. Specifically, the slopes are provided so as to be high at the ridge line T and low toward the left-and-right sides. In addition, the bottom surface E2 on the front side from the standing position of the eave portion 18 is located at a position on the upper side from the liquid passage 16, and the front side bottom surface E2 is provided with a slope toward the liquid passage 16.

[0090] ​​​The vent 17 is located at the end of the ridge line T on the rear side, is provided smaller than the liquid passage 16, and is substantially rectangular in shape when viewed from above. That is, the vent 17 is located higher than the liquid passage 16, and is located at the uppermost portion in the bottom surface on the inner side of the bottom wall portion 14c. In addition, the vent 17 is located at the uppermost portion in the bottom surface on the inner side of the bottom wall portion 14c, and is opened at a corner portion formed by the inner side surface of the bottom wall portion 14c and the lower side port forming portion 14b.

[0091] In the cap unit 1 of the present embodiment, as shown in Figures 13 to 15 When the cap body 8 is disposed upside down in the opened state with the filling port portion 15 on the lower side in a state where the cap body 8 has been removed from the container body 2, the rear side bottom surface E3 in the bottom surface on the outer side of the bottom wall portion 14c, which is located on the rear side of the opening edge portion 16a of the liquid passage 16, is located higher than the vent 17, and a slope is provided toward the vent 17 in the rear side bottom surface E3.

[0092] A slope is provided toward the vent 17 from the opening edge portion 16a on the rear side of the liquid passage 16 in the bottom surface on the outer side of the bottom wall portion 14c, and a slope is provided toward the vent 17 from the outer peripheral side of the port forming member 14. That is, in a case where the cap body 8 is disposed upside down in the opened state, the vent 17 becomes a state where it is located at the lowermost portion in the bottom surface on the outer side of the bottom wall portion 14c.

[0093] In addition, the bottom surface E3 is provided with slopes that are mutually reversed toward the ridge line T. Specifically, in a case where the cap body 8 is disposed upside down in the opened state, slopes are provided in a manner that the ridge line T is low in the central portion, and becomes lower toward the ridge line T from both left and right sides.

[0094] The cap body 8 is detachably attached to the neck portion 2c of the container body 2 by screwing in a state where the lower side port forming portion 14b is inserted into the inside of the container body 2 from the upper opening portion 2d of the container body 2. Therefore, a first outer thread portion 19 is provided on the outer peripheral surface of the neck portion 2c (container body 2). On the other hand, a first inner thread portion 20 that screws with the first outer thread portion 19 is provided on the inner peripheral surface of the peripheral wall portion 13a of the outer cylinder member 13 (cap body 8).

[0095] Thus, the cap body 8 closes the upper opening portion 2d of the container body 2 in a state where it is attached to the neck portion 2c of the container body 2, and communicates with the inside of the container body 2 via the liquid passage 16 and the vent 17.

[0096] As shown in Figures 5 to 7 A waterproof gasket 21 that seals between the port forming member 14 and the container body 2 is detachably attached to the outer peripheral portion on the lower end side of the lower side port forming portion 14b (port forming member 14).

[0097] The waterproof gasket 21 is an annular sealing member made of elastic components such as heat-resistant rubber or elastomers, and is embedded in the lower flange portion 14d provided on the outer periphery of the lower end side of the lower opening forming portion 14b. In addition, on the outer peripheral surface of the waterproof gasket 21, two upper and lower elastic flange portions 21a are provided that protrude throughout the entire circumferential expansion direction.

[0098] In the cap unit 1 of this embodiment, when the cap body 8 is installed on the neck portion 2c of the container body 2, the lower opening forming portion 14b is embedded inside the container body 2, and the elastic flange portion 21a of the waterproof gasket 21 elastically deforms, thus becoming in close contact with the protrusion 6 of the container body 2 throughout its entire circumference. Therefore, the protrusion 6 (container body 2) and the lower opening forming portion 14b (opening member 14) can be sealed (waterproofed) via the waterproof gasket 21.

[0099] On the other hand, the waterproof liner 21 can be removed from the lower flange 14d (orifice forming member 14) by elastically deforming (stretching). Furthermore, a pinch piece (not shown) protrudes from the inner periphery of the lower end side of the waterproof liner 21 for easy removal from the lower flange 14d (orifice forming member 14). Therefore, the waterproof liner 21 and the orifice forming member 14 can be cleaned separately, maintaining hygiene between them.

[0100] Furthermore, the waterproof gasket 21 is not limited to the shape described above. For example, the number of elastic flange portions 21a is not limited to two, but can be one or more than three. Additionally, the waterproof gasket 21 is not limited to a configuration with the aforementioned elastic flange portions 21a, and its shape can be appropriately modified. Furthermore, the waterproof gasket 21 is not limited to a configuration where it is easily attached and detached from the mouth-forming member 14; it can also be integrally formed with the mouth-forming member 14 in a non-separable state.

[0101] like Figures 1 to 4 As shown, the first hinge portion 9 has: an inner hinge bearing portion 9a, which is provided to protrude upward and rearward from between the peripheral wall portion 13a and the upper wall portion 13c of the outer cylinder member 13; a pair of outer hinge bearing portions 9b, which are provided to protrude rearward from the left and right sides on the base end side of the rotating member 22 described later; and a hinge shaft 9c, which is supported on a shaft hole that passes through these hinge bearing portions 9a and 9b along the rotation axis direction (left and right direction) when the inner hinge bearing portion 9a is located between the pair of outer hinge bearing portions 9b.

[0102] like Figures 1 to 7As shown, the lid body 10 has a rotating member 22 rotatably attached to the cap main body 8 at the base end side by a first hinge portion 9, a cap member 23 attached so as to freely rotate about an axis with respect to a gasket portion 22a provided at the front end side of the rotating member 22, and a plug member 24 protruding downward from the inner side lower surface central portion of the cap member 23.

[0103] The rotating member 22 is composed of, for example, a heat-resistant resin, and has a gasket portion 22a formed in a substantially cylindrical shape as a whole. Further, the gasket portion 22a has a shape in which the outer peripheral portion on the upper side is reduced in diameter with respect to the outer peripheral portion on the lower side of a stepped portion 22b inclined downward in a diameter-increasing direction toward the outer peripheral portion. An annular protrusion 22c is provided on the gasket portion 22a so as to protrude in the diameter-increasing direction from the outer peripheral portion on the upper end side throughout the entire circumference.

[0104] The cap member 23 has a peripheral wall portion 23a formed in a substantially cylindrical shape, and a top wall portion 23b covering the upper portion of the peripheral wall portion 23a. Further, an annular protrusion 23c is provided on the inner peripheral portion on the lower end side of the peripheral wall portion 23a so as to protrude in the diameter-reducing direction throughout the entire circumference. The cap member 23 is stopped with the annular protrusion 23c positioned between the stepped portion 22b and the annular protrusion 22c of the gasket portion 22a, and thereby attached so as to freely rotate about the central axis of the gasket portion 22a.

[0105] In the lid body 10, in a state in which the cap member 23 is attached to the gasket portion 22a, the outer peripheral surface of the peripheral wall portion 23a (cap member 23) is substantially coplanar with the outer peripheral surface on the lower side of the gasket portion 22a (rotating member 22).

[0106] Further, in the lid body 10, the annular protrusion 23c is movable in the up-and-down direction between the stepped portion 22b and the annular protrusion 22c of the gasket portion 22a. Thereby, the central axis of the cap member 23 can be inclined with respect to the central axis of the gasket portion 22a throughout the entire circumference, while maintaining the state in which the cap member 23 is rotatably attached to the gasket portion 22a.

[0107] The plug member 24 constitutes a plug portion that closes the liquid passage 16 and the air passage 17 in a state in which the plug member 24 is embedded inside the inner side of the mouth forming member 14. Specifically, the plug member 24 has a bottomed substantially cylindrical shape, and is integrally attached to the lower surface central portion of the top wall portion 23b by fusion or the like. Further, a heat insulating material S composed of, for example, a foamed polyurethane resin or the like is arranged as a heat insulating layer on the inner side of the plug member 24. Further, as the heat insulating layer, air (voids) can be used instead of the heat insulating material S described above.

[0108] In the cap unit 1 of the present embodiment, the cap body 10 is installed so as to freely pivot in the up-and-down direction between a position at which the cap body 10 closes the liquid passage 16 and the air passage 17 (hereinafter referred to as "closed position"), and a position at which the cap body 10 opens the liquid passage 16 and the air passage 17 (hereinafter referred to as "open position") by means of the first hinge portion 9. In addition, in the cap body 10, the pivot member 22 pivots in the up-and-down direction together with the cap member 23 and the plug member 24 by means of the first hinge portion 9.

[0109] In addition, in the cap unit 1 of the present embodiment, the cap member 23 is installed so as to be freely attached and detached with respect to the port forming member 14 (cap main body 8) by screwing from a state in which the plug member 24 is inserted inside the port forming member 14. Therefore, a second internal thread portion 25 is provided on the inner peripheral surface of the port forming member 14. On the other hand, a second external thread portion 26 that is screwed with the second internal thread portion 25 is provided on the outer peripheral surface of the plug member 24.

[0110] In the cap unit 1 of the present embodiment, the cap member 23 is movable in the up-and-down direction with respect to the grommet portion 22a described above, and the central axis of the cap member 23 is tiltable with respect to the central axis of the grommet portion 22a. Therefore, the central axis of the port forming member 14 and the central axis of the plug member 24 can be made to coincide with each other, and the second internal thread portion 25 and the second external thread portion 26 can be smoothly screwed.

[0111] In addition, the second internal thread portion 25 and the second external thread portion 26 are constituted by two threads that are complementary to each other. In the case of using two threads, the cap member 23 can be attached and detached with a small number of rotation operations (about 180° in the present embodiment).

[0112] Specifically, in the two threads described above, there are two positions at which the second internal thread portion 25 and the second external thread portion 26 are screwed. That is, a pair of thread teeth that form the second internal thread portion 25 and a pair of thread teeth that form the second external thread portion 26 are formed in a helical shape at a prescribed interval, and the start end of one of the thread teeth that constitute the pair of thread teeth and the start end of the other thread teeth are disposed so as to have a phase difference of 180° around the respective axes.

[0113] In the cap unit 1 of the present embodiment, the start position of the screwing of the second internal thread portion 25 with respect to the second external thread portion 26 is provided at a position other than a part of the inner peripheral portion of the front side and the rear side of the port forming member 14. Specifically, the start ends of the pair of thread teeth that constitute the second internal thread portion 25 are provided at a position other than a part of the inner peripheral portion of the front side and the rear side on the inside of the port forming member 14.

[0114] Thus, in the cap unit 1 of the present embodiment, the thread of the second internal thread portion 25 is not formed on a part of the inner periphery of the front side and the rear side of the mouth forming member 14, and therefore, when the turning member 22 is turned with respect to the cap main body 8 toward the closed position and the plug member 24 is inserted into the inside of the mouth forming member 14, it is possible to prevent the interference of the threads of the second internal thread portion 25 and the second external thread portion 26 with each other on the rear side close to the first hinge portion 9. In addition, it is possible to bring the first hinge portion 9 close to the mouth forming member 14, and thus it is possible to make the cap unit 1 compact.

[0115] In addition, in the cap unit 1 of the present embodiment, the thread of the second internal thread portion 25 is not formed on a part of the inner periphery of the front side of the mouth forming member 14, and therefore, when the beverage (liquid) in the container main body 2 is drunk through the injection port 15, it is possible to prevent the outflow of the beverage from being hindered by the thread of the second internal thread portion 25, and thus it is possible to achieve smooth flow.

[0116] On the outer periphery of the lower end side of the plug member 24, a plug gasket 27 that seals the space between the plug member 24 and the mouth forming member 14 is detachably attached. The plug gasket 27 is, for example, a ring-shaped sealing member composed of a rubber having heat resistance such as silicone rubber, an elastic member, or the like, and is attached by being inserted into a lower flange portion 24a provided so as to protrude from the outer periphery of the lower end side of the plug member 24.

[0117] On the other hand, on the inner periphery of the mouth forming member 14, a sealing inclined surface 14e that is in close contact with the plug gasket 27 over the entire circumference is provided. The sealing inclined surface 14e is provided so as to be inclined downward toward the reduced diameter direction at a position higher than the liquid passage 16 and the air passage 17. In addition, on the inner periphery of the mouth forming member 14, above the sealing inclined surface 14e and below the second internal thread portion 25, a stepped protruding portion 14f that protrudes inward more than the second internal thread portion 25 and whose lower end is continuous with the outer peripheral side of the sealing inclined surface 14e is provided. Further, on the front side of the sealing inclined surface 14e, a groove portion 14g that cuts a part of the protruding portion 14f is provided. The groove portion 14g is provided so as to cut a part of the protruding portion 14f with a width W2 that is smaller than the width W1 of the part of the inner periphery of the front side of the mouth forming member 14 other than the second internal thread portion 25.

[0118] In the cap unit 1 of the present embodiment, when the cap 10 is attached to the cap main body 8, the plug member 24 is inserted into the inside of the mouth forming member 14, and the plug gasket 27 is elastically deformed, and becomes in a state of being in close contact with the sealing inclined surface 14e of the mouth forming member 14 over the entire circumference. Thus, it is possible to seal (occlude) the space between the sealing inclined surface 14e (the mouth forming member 14) and the plug member 24 with the plug gasket 27.

[0119] On the other hand, the peg pad 27 is capable of being removed from the lower flange portion 24a (the peg member 24) by elastically deforming (stretching) itself. In addition, a pinch tab 27a for easily removing the peg pad 27 from the lower flange portion 24a (the peg member 24) is provided protruding at the inner periphery of the lower end side of the peg pad 27. Thus, the peg pad 27 and the peg member 24 (the lid 10) can be separately and individually cleaned, and the hygiene between the peg pad 27 and the peg member 24 can be maintained.

[0120] Further, the peg pad 27 is not necessarily limited to the above-described shape, and the shape and the like thereof can be appropriately changed.

[0121] As shown in Figures 1 to 7 , the cap unit 1 of the present embodiment is provided with a rotation stopping mechanism 28 that prevents the rotation member 22 (the lid 10) that has been rotated to the open position from being rotated toward the closed position.

[0122] The rotation stopping mechanism 28 has a hook receiving portion 28a provided on the outer cylinder member 13 (the cap main body 8) side, and a hook portion 28b provided on the rotation member 22 (the lid 10) side. The hook receiving portion 28a is constituted by a protrusion portion that protrudes rearward from the inner side hinge bearing portion 9a rear end side. On the other hand, the hook portion 28b is constituted by an elastic piece that extends obliquely downward between the pair of outer side hinge bearing portions 9b, and a claw portion that protrudes rearward from the front end of the elastic piece.

[0123] In the rotation stopping mechanism 28, in the above-described open position, the hook portion 28b is latched to the hook receiving portion 28a, whereby the rotation member 22 (the lid 10) can be prevented from being rotated toward the closed position. Thus, in the capped container 100 provided with the cap unit 1 of the present embodiment, when the container main body 2 is tilted forward and the beverage in the container main body 2 is caused to flow out from the liquid passage 16, the lid 10 can be prevented from being rotated toward the closed position due to the weight thereof, and the lid 10 can be maintained in the open position in a stable state.

[0124] Further, the rotation stopping mechanism 28 is not necessarily limited to the above-described hook receiving portion 28a and hook portion 28b, and the configuration thereof can be appropriately changed.

[0125] As shown in Figure 1 and Figure 2 , the handle member 12 is constituted by a ring-shaped resin member, and is installed so as to be freely rotatable in the up-down direction with respect to the rear side surface (the peripheral wall portion 13a) of the outer cylinder member 13 (the cap main body 8) by the second hinge portion 11 located below the first hinge portion 9. Thus, in the capped container 100 provided with the cap unit 1 of the present embodiment, the handle member 12 can be held while being manually moved.

[0126] In the capped container 100 of this embodiment, which has the cap unit 1 with the above-described configuration, when drinking the beverage in the container body 2, the container body 2 is tilted forward by keeping the cap 10 in the open position by the anti-rotation mechanism 28, thereby allowing the beverage in the container body 2 to be poured out from the inlet 15 through the liquid outlet 16.

[0127] Furthermore, when the beverage inside the container body 2 is poured out through the inlet 15 via the liquid inlet 16, external air is introduced into the interior of the container body 2 through the vent 17. As a result, the beverage flowing out of the liquid inlet 16 can be poured out smoothly along the groove 14g and the inlet 15 without pulsation or with reduced pulsation.

[0128] Furthermore, in the capped container 100 equipped with the cap unit 1 of this embodiment, the beverage flowing out of the liquid inlet 16 is temporarily blocked by the rim 18 opposite to the liquid inlet 16. This prevents the beverage from violently spraying out of the liquid inlet 16 towards the inside of the mouth-forming member 14 due to the angle and speed of the tilted container body 2, allowing a suitable amount of beverage to be poured out from the slit-like portion between the liquid inlet 16 and the rim 18. Additionally, even ice that has become somewhat smaller can be blocked, thus suppressing the flow of ice.

[0129] Furthermore, in the capped container 100 equipped with the capping unit 1 of this embodiment, when the beverage inside the container body 2 is poured out from the inlet 15 through the liquid inlet 16, and the container body 2 is returned from a state where it is tilted forward to a state where it is upright, the slope of the bottom surfaces E1 and E2 provided on the inner side of the bottom wall portion 14c allows the beverage flowing out from the liquid inlet 16 to the inside of the mouth forming member 14 to quickly return from the liquid inlet 16 to the inside of the container body 2.

[0130] That is, such as Figure 9 As shown by arrow L1, the beverage flowing from the liquid inlet 16 toward the inside of the mouth forming member 14 flows down the bottom surface E1 on both sides of the vertical wall 18a of the eaves 18, which is located behind the vertical wall 18a of the eaves 18, around the opening edge 16b on the front side, and then flows toward the inside of the liquid inlet 16.

[0131] Furthermore, the rear opening edge 16a is formed into a shallow V-shape in the left-right direction when viewed from above. Therefore, when the container body 2 is returned to an upright position, the beverage present in the rear opening edge 16a easily flows along the edge toward both ends of the V-shape. Thus, the beverage will not remain in the rear opening edge 16a, but will easily flow down to the inside of the liquid inlet 16.

[0132] On the other hand, such as Figure 9 As shown by arrow L2, the beverage flowing from the inlet 16 toward the inside of the opening forming member 14 flows down the bottom surface E2 of the vertical wall 18a of the eaves 18 from the front opening edge 16b toward the inside of the inlet 16.

[0133] Therefore, when the container body 2 is returned to an upright position, it is possible to prevent beverage residue flowing from the inlet 16 to the inside of the mouth-forming member 14 from remaining between the mouth-forming member 14 and the stopper member 24. Thus, regardless of whether the cap 10 is open or closed, it equally prevents beverage residue adhering to the inside of the mouth-forming member 14, thereby preventing splashing of beverage residue on the inside of the mouth-forming member 14 when the cap 10 is reopened, and preventing colored beverage residue adhering to the inside of the mouth-forming member 14 from appearing as dirt.

[0134] Furthermore, in the cap unit 1 of this embodiment, as Figures 13 to 15 As shown, after cleaning the cap unit 1, with the cap 10 held in the open position by the aforementioned anti-rotation mechanism 28, the cap body 8 is placed in the water control basket with the inlet 15 facing down in a reversed position.

[0135] At this time, as Figures 13 to 15 As indicated by arrow L3, by the slope of the bottom surface E3 on the outer side of the bottom wall portion 14c, the residual liquid adhering to the bottom surface E3 on the outer side of the bottom wall portion 14c can flow rapidly along the ridge line T toward the vent 17, and be guided to the lower water control basket through the inner side of the vent forming component 14.

[0136] Therefore, when cleaning the cap unit 1, the cap unit 1 can be kept hygienic due to its easy-to-control and dry structure.

[0137] As described above, in the cap unit 1 of this embodiment, it is easy to drink the beverage flowing from the liquid inlet 16 to the inside of the mouth forming member 14, and it can improve cleanability while preventing beverage residue from adhering to the mouth forming member 14.

[0138] Therefore, the capped container 100 of this embodiment includes such a capping unit 1, thereby further improving ease of use.

[0139] Furthermore, the present invention is not limited to the above-described embodiments and various modifications can be made without departing from the spirit of the present invention.

[0140] For example, in the above-described embodiment, the cap unit 1 provided with the lid 10 including the rotating member 22 rotatably attached to the cap main body 8 at the base end side by the first hinge portion 9 and the cap member 23 attached to freely rotate around the axis with respect to the gasket portion 22a provided at the front end side of the rotating member 22 is exemplified, but a configuration provided with a lid locking mechanism rotatably attached to the cap main body and fixing the lid provided with the plug portion closing the liquid passage with respect to the cap main body can also be exemplified.

[0141] Further, in the above-described embodiment, the case where the present application is applied to the beverage container having the heat retaining and cold retaining function by the container main body 2 having the above-described vacuum heat insulating structure is exemplified, but the present application can be widely applied to the cap-equipped container provided with the container main body and the cap unit attachable and detachable to the container main body.
