Description

Technical Field

[0001] This invention relates to lid units and lidded containers. Background Technology

[0002] Previously, there were cap units (plugs) that could be easily installed and removed from the container body with an upper opening (for example, see Patent Document 1).

[0003] The cap unit includes: a cap body that closes the upper opening of the container body and has a liquid inlet communicating with the inside of the container body; and a cap body that opens and closes the liquid inlet when rotatably mounted on the cap body via a first hinge. Additionally, the cap unit includes a cap locking mechanism that applies force to the cap body toward the open liquid inlet via a first force-applying member provided at the first hinge, and fixes the cap body in the closed liquid inlet position by overcoming the force applied by the first force-applying member.

[0004] The lid locking mechanism includes a locking member that is rotatably mounted to the lid body via a second hinge. The locking member rotates between a locked position where one locking portion located on one end is engaged with another locking portion located on the lid body side, and a unlocked position where the engagement of one locking portion with the other is released. Furthermore, the lid locking mechanism includes a second force-applying member that applies force to the locking member toward the locked position side in the direction of rotation.

[0005] In the cover locking mechanism, the locking member is pressed in a way that overcomes the force applied by the second force-applying member to release the cover from its fixed state (locked state), thereby allowing the cover to rotate in the opening direction by the force applied by the first force-applying member.

[0006] In a lidded container equipped with such a lid unit, the lid locking mechanism is released from its locked state, causing the lid to rotate in the opening direction, thereby opening the liquid inlet. This allows the beverage inside the container to be drunk through the liquid inlet.

[0007] Patent Document 1: Japanese Patent Application Publication No. 2010-23854

[0008] However, in existing lidded containers equipped with the aforementioned lid unit, when the lid locking mechanism releases the lid from its locked state, the lid, which is subjected to force by the first force-applying component, rotates forcefully in the opening direction, resulting in beverage adhering to the inside of the lid splashing outwards. In particular, if the pressure inside the container body increases, the speed at which the lid rotates in the opening direction will increase. Summary of the Invention

[0009] The present invention was made in view of this existing situation, and aims to provide a lid unit that prevents the lid from being forcefully rotated in the opening direction when the lid locking mechanism is released from the locked state of the lid, and a lidded container that can further improve the ease of use by having such a lid unit.

[0071] like Figure 1 as well as Figure 2 As shown, the lidded container 100 of this embodiment includes a lid unit 1 of this embodiment and a container body 2 for the lid unit 1 to be easily installed and removed. The lidded container 100 is a beverage container that can keep the beverage (contents) contained in the container body 2 warm or cold through the container body 2 having a vacuum insulation structure.

[0072] Specifically, the container body 2 is composed of a double-layered container, which has a bottomed cylindrical outer container 3 made of, for example, stainless steel, and an inner container 4. The two layers are joined by connecting their opening edges while the inner container 4 is housed inside the outer container 3. Furthermore, 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 an exhaust vent located at the center of the bottom surface of the outer container 3 within a chamber that has been depressurized (evacuated) to a high vacuum.

[0073] The container body 2 has a generally circular bottom portion 2a, a generally cylindrical cylindrical body portion 2b that rises from the outer periphery of the bottom portion 2a, and a generally cylindrical neck portion 2c that is tapered at the upper side of the cylindrical body portion 2b. The upper end of the neck portion 2c has a circular opening, serving as the upper opening 2d of the container body 2. Furthermore, the inner circumferential surface of the neck portion 2c is tapered compared to the inner circumferential surface of the cylindrical body portion 2b. Additionally, an annular protrusion 6 is provided protruding along the entire circumference of the inner circumferential surface of the neck portion 2c.

[0074] Furthermore, the lidded container 100 of this embodiment has a generally cylindrical external shape, but the external shape of the lidded container 100 is not particularly limited and can be appropriately modified according to size, appearance design, etc. In addition, painting, printing, etc. can also be performed on the outer peripheral surface of the container body 2.

[0075] In this embodiment, the cover unit 1 constitutes a plug that closes the upper opening 2d of the container body 2. Specifically, as... Figures 3-7 As shown, the cover unit 1 includes a cover body 7 and a cover 9 that is rotatably mounted on the cover body 7 via a first hinge portion 8.

[0076] Furthermore, in the following description, the side on which the cover body 9 is mounted relative to the cover body 7 via the first hinge portion 8 will be referred to as the "rear side (back side)" of the cover unit 1 (covered container 100), and the side opposite to it will be referred to as the "front side (front face)" of the cover unit 1 (covered container 100).

[0077] The lid body 7 is made of a heat-resistant resin such as polypropylene (PP). The lid body 7 has: a peripheral wall portion 7a, 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 7c, which is formed by forming an opening 7b at the upper part of the peripheral wall portion 7a that is narrower than the peripheral wall portion 7a.

[0078] The cap body 7 is detachably mounted to the neck portion 2c of the container body 2 by screwing it on. Therefore, an internal thread portion 10 is provided on the inner circumferential surface of the peripheral wall portion 7a. On the other hand, an external thread portion 11 that engages with the internal thread portion 10 is provided on the outer circumferential surface of the neck portion 2c.

[0079] like Figures 3-9 As shown, a mouth-forming component 12, forming a drinking spout or injection spout (drinking spout in this embodiment), is detachably installed at the opening 7b of the cap body 7. The mouth-forming component 12 is made of, for example, a heat-resistant resin such as polypropylene (PP). A generally circular liquid inlet 13 communicating with the inside of the container body 2 is provided on the mouth-forming component 12.

[0080] The mouth-forming component 12 includes: a bottom wall portion 12a having a liquid inlet 13; a cylindrical peripheral wall portion 12b that rises upward from around the bottom wall portion 12a; a lower flange portion 12c that protrudes annularly from the lower end of the outer peripheral surface of the bottom wall portion 12a; a pair of upper flange portions 12d that protrude laterally from the upper end of the outer peripheral surface of the peripheral wall portion 12b to opposite sides; and a drinking mouth portion 12e that protrudes obliquely from the upper end of the front side of the peripheral wall portion 12b.

[0081] An opening removal and installation mechanism 14 is provided between the cover body 7 and the opening forming member 12 for freely installing and removing the opening forming member 12 at the opening 7b of the cover body 7. The opening removal and installation mechanism 14 has a first claw 15 on the front side of the opening forming member 12 and a locking member 17 with a second claw 16 on the rear side of the opening forming member 12.

[0082] The first claw portion 15 is configured to protrude forward from the upper end of the outer peripheral surface of the peripheral wall portion 12b. The second claw portion 16 is configured to protrude rearward from the upper end (front end) of the locking member 17.

[0083] The locking member 17 is mounted via a hinge portion 18 located at the lower end of the rear side of the opening forming member 12, allowing it to rotate freely in the front-rear direction. The hinge portion 18 includes: a first hinge bearing portion 12f located in the opening forming member 12; a second hinge bearing portion 17a and a third hinge bearing portion 17b located in the locking member 17; and a hinge shaft 19, which is mounted with shaft holes 12g, 17c, and 17d provided in the first hinge bearing portion 12f, the second hinge bearing portion 17a, and the third hinge bearing portion 17b, passing through the rotation axis direction. Furthermore, an operating portion 17e is provided at the upper end of the locking member 17, having a recess or protrusion for easy rotation of the locking member 17 by a finger.

[0084] A force-applying member 20 is disposed between the mouth-forming member 12 and the locking member 17, applying force to the rear side of the locking member 17 in the direction of rotation. The force-applying member 20 is made of an elastic component such as heat-resistant rubber or an elastomer, for example. The force-applying member 20 is mounted on the surface of the locking member 17 opposite to the mouth-forming member 12 by inserting a mounting protrusion 22 provided on the front side of the locking member 17 into a mounting hole 21 provided on the rear side of the force-applying member 20.

[0085] When the front end of the locking member 17 is rotated forward, the force-applying member 20 is compressed (elastically deformed) between the locking member 17 and the orifice forming member 12, thereby applying a force to the locking member 17 in the rearward direction.

[0086] The opening / closing mechanism 14 has a first locking part 23 on the front side of the cover body 7 and a second locking part 24 on the rear side of the cover body 7. The first locking part 23 and the second locking part 24 are formed by stepped parts provided on the upper wall part 7c at the front and rear positions along the opening 7b, respectively.

[0087] In the opening / closing mechanism 14, with the first claw 15 positioned relative to the first locking portion 23, the opening forming member 12 is inserted from below into the inside of the opening 7b of the cover body 7. At this time, the pair of upper flanges 12d abut against the lower surface of the upper wall portion 7c of the cover body 7. The first claw 15 is also locked by the first locking portion 23. Furthermore, the second claw 16 abuts against the edge of the opening 7b of the cover body 7, and the second claw 16 extends beyond the edge of the opening 7b. Simultaneously, the front end of the locking member 17 rotates forward, and then the front end of the locking member 17 returns to its original rearward position. At the same time, the second claw 16 is locked by the second locking portion 24.

[0088] Thus, the mouth-forming member 12 is installed in the opening 7b of the cap body 7. In addition, when the mouth-forming member 12 is installed, the drinking spout 12e protrudes outward (upward) from the opening 7b of the cap body 7.

[0089] On the other hand, in the mouth-opening / removing mechanism 14, the locking state of the second claw 16 relative to the second locked portion 24 is released by rotating the front end of the locking member 17 forward. This releases the locking state of the first claw 15 relative to the first locked portion 23, and allows the mouth-forming member 12 to be removed from the underside of the opening 7b of the cover body 7. This allows the mouth-forming member 12 and the cover body 7 to be cleaned separately, thus maintaining hygiene between them.

[0090] The cap body 7, on which the mouth forming member 12 is installed, is installed on the neck portion 2c of the container body 2, thereby closing the upper opening 2d of the container body 2 with the mouth forming member 12 embedded inside the upper opening 2d.

[0091] like Figures 3-6 As shown, a waterproof sealant 25 is detachably installed on the lower flange portion 12c of the mouth-forming component 12. The waterproof sealant 25 is an annular sealing component used to seal the protrusion 6 (container body 2) and the mouth-forming component 12 (cap body 7). The waterproof sealant 25 is made of, for example, heat-resistant rubber such as silicone rubber, or an elastic component such as an elastomer. The waterproof sealant 25 is fitted into the outer periphery of the lower flange portion 12c.

[0092] When the waterproof sealant 25 is embedded inside the upper opening 2d of the container body 2, it becomes elastically deformable while remaining tightly attached to the protrusion 6 of the container body 2 throughout its entire circumference. As a result, the protrusion 6 and the opening forming member 12 can be sealed.

[0093] On the other hand, the waterproof sealant 25 can be removed from the lower flange portion 12c (orifice forming member 12) by elastically deforming (stretching). As a result, the waterproof sealant 25 and the orifice forming member 12 can be cleaned separately, thereby maintaining hygiene between the waterproof sealant 25 and the orifice forming member 12.

[0094] The cover 9 opens and closes the liquid inlet 13 of the opening forming member 12, and is made of, for example, a heat-resistant resin such as polypropylene (PP). The cover 9 has: a peripheral wall portion 9a, which is formed in a generally cylindrical shape in a manner continuous with the peripheral wall portion 7a of the cover body 7; a top wall portion 9b, which covers the top surface of the peripheral wall portion 9a; and a generally cylindrical inner wall portion 9c, which descends from the lower surface of the top wall portion 9b while penetrating the top wall portion 9b.

[0095] The cover 9 is subjected to force by the first force-applying member 26 located inside the first hinge portion 8 (described later) in the direction of the liquid inlet 13 of the opening forming member 12 (hereinafter referred to as the opening direction).

[0096] A sealing member 27 is provided on the inner side of the cover body 9 for the liquid inlet 13 of the closing port forming member 12. The sealing member 27 is a plug-shaped sealing member used to seal the liquid inlet 13. The sealing member 27 is made of an elastic member and can be made of the same material as the waterproof sealing member 25 described above.

[0097] The sealing member 27 is a bottomed cylindrical sealing component that is detachably and removably installed on the inner wall portion 9c of the cover body 9. Specifically, the sealing member 27 is detachably and removably installed on the lower end side of the inner wall portion 9c with the inner wall portion 9c embedded in its inner central hole 27a. In addition, the front end of the sealing member 27 is formed into a dome shape.

[0098] The sealing member 27 is installed relative to the cover body 9 by embedding its inner wall portion 9c into the inner side of the central hole 27a. Thus, in the cover unit 1, when the cover body 9 closes the upper part of the cover body 7, the sealing member 27 is in a state of elastic deformation while tightly adhering to the periphery of the liquid inlet 13. This allows the liquid inlet 13 of the opening forming member 12 to be closed.

[0099] On the other hand, by removing the sealing cap 27 from the inner wall portion 9c (cap 9), the sealing cap 27 and the cap 9 can be cleaned separately, thereby maintaining hygiene between the sealing cap 27 and the cap 9.

[0100] A cover member 28 is installed on the upper surface of the top wall portion 9b, covering the upper end of the inner wall portion 9c. The cover member 28 is made of the same material as the cover body 9 and is formed into a generally circular plate shape. On the other hand, a recess 29 with a shape corresponding to the cover member 28 is provided on the upper surface of the top wall portion 9b. The cover member 28 is fitted into the inside of the recess 29.

[0101] The cover unit 1 includes a cover locking mechanism 36, which fixes the cover body 9 relative to the cover body 7 in a position where the liquid inlet 13 is closed (hereinafter referred to as the closed position) in a manner that overcomes the force applied by the first force-applying member 26.

[0102] Specifically, such as Figures 4-6 as well as Figures 10-15 As shown, the cover locking mechanism 36 includes: a locking member 38, which is rotatably mounted to the cover body 7 via a second hinge portion 37; and an annular stop member 39, which is rotatably mounted to the cover body 7 via a second hinge portion 37.

[0103] The second hinge portion 37 includes: a first hinge bearing portion 40 disposed on the locking member 38; a second hinge bearing portion 41 and a third hinge bearing portion 42 disposed on the cover body 7; and a hinge shaft 43, which is installed with the first hinge bearing portion 40 located between the second hinge bearing portion 41 and the third hinge bearing portion 42, and with the shaft holes 40a, 41a, and 42a provided in the first hinge bearing portion 40, the second hinge bearing portion 41, and the third hinge bearing portion 42 passing through the shaft holes 40a, 41a, and 42a provided in the first hinge bearing portion 40, the second hinge bearing portion 41, and the third hinge bearing portion 42 along the rotation axis direction.

[0104] The locking member 38 is supported by a second hinge portion 37 located on the side (peripheral wall portion 7a) of the front side of the cover body 7, allowing it to rotate freely. The locking member 38 has: a first arm portion 38a, which extends upward from the second hinge portion 37; and a second arm portion 38b, which extends downward from the second hinge portion 37.

[0105] A hook portion 44, which serves as a locking part, is provided at the front end of the first arm portion 38a (the upper end of the locking member 38) and protrudes rearward. On the other hand, a hook receiving part 45, which serves as a locking part for the hook portion 44 of the locking member 38, is provided on the side (peripheral wall portion 9a) of the front side of the cover 9 and protrudes forward.

[0106] The locking member 38 rotates between a position in which the hook portion 44 is engaged with the hook receiving portion 45 (hereinafter referred to as the "locked position") and a position in which the hook portion 44 is released from the engaged state with the hook receiving portion 45 (hereinafter referred to as the "locked-out position").

[0107] A second force-applying component 46 is disposed between the second arm portion 38b and the peripheral wall portion 7a. The second force-applying component 46 is made of elastic components such as heat-resistant rubber or elastomers, and is easy to color, unlike metals.

[0108] The second force-applying member 46 is rotatably mounted via the second hinge portion 37 and applies force to the locking member 38 toward the locking position side in the direction of rotation. Specifically, the second force-applying member 46 has: an elastically deformable portion 46a located between the second arm portion 38b and the peripheral wall portion 7a; and a support plate portion 46c extending upward from the elastically deformable portion 46a and having a shaft hole 46b.

[0109] The elastically deformable portion 46a is configured to extend in a generally elongated cylindrical shape along the front-rear direction. Furthermore, a generally cylindrical fitting protrusion 46d is provided at the front end of the elastically deformable portion 46a, protruding forward. On the other hand, a fitting hole 47 is provided in the second arm portion 38b of the locking member 38 for fitting the fitting protrusion 46d. Moreover, the fitting hole 47 does not necessarily have to be a structure that penetrates the second arm portion 38b; it can also be a fitting recess for fitting the fitting protrusion 46d.

[0110] The support plate portion 46c is configured to extend in the vertical direction in a generally flat shape. On the other hand, a slit portion 48 is provided in the first hinge bearing portion 40 for the support plate portion 46c to be inserted.

[0111] Therefore, the second force-applying member 46 is integrally installed with the locking member 38 with the fitting protrusion 46d fitting into the fitting hole 47 and the support piece 46c inserted into the inside of the slit 48. Furthermore, the second force-applying member 46 is rotatably installed together with the locking member 38 via the second hinge portion 37 with the hinge shaft 43 passing through the shaft hole 46b in the rotation axis direction.

[0112] Therefore, when the second force-applying member 46 presses on the second arm 38b side of the locking member 38, the elastic deformation part 46a is compressed between the second arm 38b and the peripheral wall part 7a, thereby applying force to the locking member 38 toward the locking position side in the rotation direction.

[0113] The cover locking mechanism 36 has a cover member 49 made of metal, such as stainless steel, that covers the locking member 38. The cover member 49 has: a cover body 49a that covers the locking member 38; and a pair of support arms 49c that protrude from the cover body 49a on both sides separated by the first hinge bearing portion 40, and are provided with shaft holes 49b through which the hinge shaft 43 passes. In addition, the plate thickness of the cover member 49 is preferably about 0.2 to 1.0 mm.

[0114] Furthermore, the cover member 49 has a fixing mechanism that fixes the cover member 49 to the first hinge bearing portion 40 via a pair of support arms 49c. It has a locking protrusion 49d that protrudes upward and downward from the front end of the pair of support arms 49c, and a locking recess 40b that locks the locking protrusion 49d on both sides of the first hinge bearing portion 40.

[0115] Therefore, the cover member 49 is integrally installed with the locking member 38 in a state where the cover body 49a covers the front side of the locking member 38 and the locking protrusions 49d of the pair of support arms 49c are engaged with the locking recesses 40b of the first hinge bearing portion 40. Furthermore, the cover member 49 is rotatably installed together with the locking member 38 via the second hinge portion 37 with the hinge shaft 43 passing through the shaft hole 49b in the rotation axis direction.

[0116] Thus, the cover member 49, while covering the locking member 38, rotates together with the locking member 38 between the locked position and the unlocked position.

[0117] The annular stop 39 is composed of a partially open annular component with shaft holes 39a at both ends through which the hinge shaft 43 passes, and is rotatably supported on the outside of the second hinge portion 37 (the second hinge bearing portion 41 and the third hinge bearing portion 42). Thus, the annular stop 39 can rotate in the vertical direction.

[0118] On the other hand, a stop receiving portion 50 for the annular stop 39 to be fastened is provided on the side (peripheral wall portion 9a) of the front side of the cover 9. The stop receiving portion 50 is configured to protrude forward from the position surrounding the hook receiving portion 45 with a shape corresponding to the inner side of the annular stop 39.

[0119] In the lid locking mechanism 36, when the lid 9 closes the upper part of the lid body 7, the hook portion 44 of the locking member 38 engages with the hook receiving portion 45, thereby maintaining the state in which the lid 9 closes the upper part of the lid body 7 (hereinafter referred to as the "locked state"). From this locked state, a pressing operation is performed on the second arm portion 38b side of the locking member 38, thereby releasing the engagement state of the hook portion 44 relative to the hook receiving portion 45. As a result, the lid 9 can be rotated in the opening direction by the force applied by the first force-applying member 26.

[0120] On the other hand, in the cover locking mechanism 36, when the cover 9 closes the upper part of the cover body 7, the annular stop 39 is engaged with the stop receiving part 50, thereby preventing the cover 9 from rotating in the opening direction. Thus, in the cover locking mechanism 36, it is possible to prevent the cover 9 from opening due to unnecessary operation of the locking member 38.

[0121] Furthermore, the cover member 49 is not necessarily limited to a fixing mechanism in which the locking protrusion 49d and the aforementioned locking recess 40b are locked together. For example, the fixing mechanism for the cover member 49 could be as follows: Figure 16 As shown, it is configured to have a pair of bent pieces 49e formed by bending the front ends of a pair of support arms 49c in opposite directions, and the first hinge bearing portion 40 is clamped by the pair of bent pieces 49e.

[0122] Additionally, the fixing mechanism for the cover component 49 can also be as follows: Figure 17 As shown, it is configured to have a locking piece 49f obtained by cutting a portion of a pair of support arms 49c, and to lock the pair of locking pieces 49f with the locking receiving portion 40c provided in the first hinge bearing portion 40.

[0123] Additionally, in the cover component 49, it is also possible to... Figure 18 As shown, the shaft hole 49b provided in the pair of support arms 49c is made into an elongated hole shape, and the protrusion 40d provided in the first hinge bearing part 40 engages with the shaft hole 49b, thereby preventing the cover part 49 from being misaligned relative to the first hinge bearing part 40 (locking part 38).

[0124] Furthermore, in this embodiment, the cover member 49 is configured to be rotatably mounted together with the locking member 38 via the second hinge portion 37 with the hinge shaft 43 passing through the shaft hole 49b in the direction of rotation. However, the second hinge portion 37 only needs to function as a hinge member and is not limited to a structure through which the hinge shaft 43 passes.

[0125] In addition, the cover component 49 can be installed in a structure that is integral with the locking component 38 and rotatably mounted relative to the second hinge portion 37. For example, it can also be a structure in which the cover component 49 and the locking component 38 are integrally mounted by the above-mentioned fixing mechanism.

[0126] In addition, in this embodiment, the second hinge portion 37 is configured to include a first hinge bearing portion 40 provided on the locking member 38, and a second hinge bearing portion 41 and a third hinge bearing portion 42 provided on the cover body 7, but it is also possible to form a structure that allows the locking member 38 side to be interchanged with the cover body 7 side.

[0127] That is, it can also be configured such that a first hinge bearing portion is provided on the side of the cover body 7, and a second hinge bearing portion and a third hinge bearing portion are provided on the side of the locking member 38. In this configuration, a pair of support arms 49c of the cover member 49 protrude from the cover body 49a on both sides of the second hinge bearing portion and the third hinge bearing portion provided on the locking member 38, and the cover member 49 is fixed to the second hinge bearing portion and the third hinge bearing portion by the hinge shaft 43 or a fixing mechanism.

[0128] In addition, such as Figures 19-28 As shown, a rotation damping mechanism 51 is provided in the first hinge part 8, which reduces the rotation speed of the cover 9 that rotates due to the force applied by the first force-applying member 26.

[0129] Specifically, the first force-applying component 26 is a torsion spring, having a coiled portion 26a, a one-sided arm 26b extending from one end of the coiled portion 26a, and another-sided arm 26c extending from the other end of the coiled portion 26a.

[0130] The first hinge portion 8 includes: a first hinge bearing portion 52, which is disposed on either the cover body 7 or the cover 9 (in this embodiment, the cover body 7); a second hinge bearing portion 53 and a third hinge bearing portion 54, which are disposed on either the cover body 7 or the cover 9 (in this embodiment, the cover 9); and a hinge shaft 55, which is installed with the first hinge bearing portion 52 located between the second hinge bearing portion 53 and the third hinge bearing portion 54, and with the shaft holes 52a, 53a, and 54a provided in the first hinge bearing portion 52, the second hinge bearing portion 53, and the third hinge bearing portion 54 passing through the shaft holes 52a, 53a, and 54a provided in the first hinge bearing portion 52, the second hinge bearing portion 53, and the third hinge bearing portion 54 along the rotation axis direction.

[0131] The first hinge bearing portion 52 has a shaft hole 52a that extends along the rotation axis and is formed in a generally cylindrical shape, and is configured to protrude from the rear center of the cover body 7.

[0132] The second hinge bearing portion 53 is configured to protrude from one side of the rear center portion of the cover body 9 in such a way that it has a shaft hole 53a that extends through the rotation axis and has a shape that is continuous with the first hinge bearing portion 52.

[0133] The third hinge bearing portion 54 is configured to protrude from the other side of the rear center portion of the cover body 9 in such a way that it has a shaft hole 54a that extends through the rotation axis and has a shape that is continuous with the first hinge bearing portion 52.

[0134] The first hinge bearing portion 52 is provided with a receiving recess 52b, which is formed by a generally cylindrical recess in the direction of rotation of the surface side opposite to the third hinge bearing portion 54. In addition, the first hinge bearing portion 52 is provided with an arm bearing portion 52c, which is formed by a recess in the surface side opposite to the third hinge bearing portion 54 corresponding to the shape of the arm portion 26b of one of the first force-applying members 26.

[0135] The first force-applying member 26 is disposed inside the first hinge bearing portion 52 in a state in which the winding portion 26a is received inside the receiving recess 52b and one arm portion 26b is engaged with one arm receiving portion 52c.

[0136] On the other hand, the third hinge bearing portion 54 is provided with a counter component 56 that forms a surface opposite to the first hinge bearing portion 52. The counter component 56 has a shaft hole 56a through which the hinge shaft 55 passes, and is installed in a state where it is inserted into the inner side of the fitting recess 54b of the third hinge bearing portion 54.

[0137] In addition, on the surface of the opposite component 56 that faces the first hinge bearing portion 52, there is a fitting protrusion 56b that protrudes in accordance with the shape of the receiving recess 52b, and an arm bearing portion 56c that is recessed in accordance with the shape of the other arm portion 26c of the first force-applying component 26.

[0138] The opposing component 56 is configured to rotate freely together with the third hinge bearing portion 54 when the fitting protrusion 56b is engaged with the receiving recess 52b and the other arm portion 26c of the first force-applying component 26 is engaged with the other arm bearing portion 56c.

[0139] Therefore, when the first force-applying component 26 rotates the cover 9 toward the side opposite to the opening direction (hereinafter referred to as the closing direction) from the position where the liquid inlet 13 is open (the open position), it elastically deforms in the direction in which the opening angle between one arm 26b and the other arm 26c narrows, thereby using its rebound force to apply force to the cover 9 toward the opening direction relative to the cover body 7.

[0140] Furthermore, regarding the opposite component 56, a material different from that of the first hinge bearing part 52 (cover body 7) can be appropriately used, such as polyoxymethylene (POM) or acrylonitrile-butadiene-styrene (ABS) materials with excellent wear resistance.

[0141] In the first hinge portion 8, by separately providing this wear-resistant opposing component 56 with the third hinge bearing portion 54, durability can be improved. Furthermore, the opposing component 56 is not limited to a structure that is separately provided with the third hinge bearing portion 54; it can also be an integral structure with the third hinge bearing portion 54.

[0142] A rotation damping mechanism 51 is disposed between the first hinge bearing portion 52 and the second hinge bearing portion 53. Specifically, the rotation damping mechanism 51 includes: a first gear 57 mounted on the first hinge bearing portion 52, a second gear 58 meshing with the first gear 57, a rotation damper 59 supporting the second gear 58 to rotate freely and applying resistance to the rotation of the second gear 58, and a damping box 60 that rotates integrally with the cover 9 while the rotation damper 59 is held.

[0143] The damping box 60 internally houses the first gear 57, the second gear 58, and the rotational damper 59, thus preventing these components from being visually observed from the outside. Furthermore, in the cover unit 1 of this embodiment, the first force-applying member 26 and the rotational damping mechanism 51 are efficiently arranged within the limited space inside the first hinge portion 8 and the cover body 9.

[0144] Furthermore, for the first gear 57 and the second gear 58, materials with excellent wear resistance, such as polyoxymethylene (POM) and acrylonitrile-butadiene-styrene (ABS), can be appropriately used.

[0145] Regarding the damping box 60, materials with excellent dimensional formability, such as polycarbonate (PC) and acrylonitrile-butadiene-styrene (ABS), can be appropriately used.

[0146] The first gear 57 has a shaft hole 57a through which the hinge shaft 55 passes, and a fixed shaft 57b protruding from the surface opposite to the first hinge bearing portion 52. The first gear 57 is integrally mounted with the first hinge bearing portion 52 with the fixed shaft 57b inserted into the fixing hole 52d provided on the surface of the first hinge bearing portion 52 opposite to the second hinge bearing portion 53.

[0147] The second gear 58 is located ahead of the first gear 57 and is supported by the rotary damper 59 in a meshing manner with the first gear 57, allowing it to rotate freely. The rotary damper 59 uses the viscous resistance of the oil filled inside to apply resistance to the rotation of the second gear 58, thereby reducing its rotational speed.

[0148] The damping box 60 has a shaft hole 60a through which the hinge shaft 55 passes, and a... Figure 7 The locking claw 60b shown is engaged by the locking hole 9d located on the inner side of the cover 9. The damping box 60 is configured to rotate freely together with the second hinge bearing portion 53.

[0149] The damping box 60 is provided with a first recess 60c, which is recessed on the surface opposite to the second hinge bearing portion 53 and corresponding to the second gear 58 and the rotary damper 59, and a second recess 60d, which is recessed on the surface opposite to the first hinge bearing portion 52 and corresponding to the first gear 57. The first recess 60c and the second recess 60d are connected at an overlapping position.

[0150] The first gear 57 and the second gear 58 mesh with each other through the first recess 60c and the second recess 60d. The rotary damper 59 has a fixing hole 59a and a fixing groove 59b through which a pair of fixing pins 60e disposed on the inner side of the first recess 60c pass, and the rotary damper 59 is fitted into the inner side of the first recess 60c.

[0151] Therefore, in the rotation damping mechanism 51, when the locking state of the cover body 9 by the cover locking mechanism 36 is released, the rotation speed of the cover body 9, which rotates from the closed position to the open position by the force applied by the first force applying member 26, can be suppressed.

[0152] Specifically, in the rotation damping mechanism 51, when the cover 9 rotates from the closed position to the open position by the force applied by the first force-applying member 26, the damping box 60 rotates together with the cover 9.

[0153] At this time, as the second gear 58, which meshes with the first gear 57, rotates, the rotation damper 59 applies resistance to the rotation of the second gear 58, thereby reducing the rotational speed of the second gear 58. As a result, the rotational speed of the cover 9, which rotates toward the open position, is suppressed to a lower level by the resistance of the rotation damper 59.

[0154] Therefore, in the cover unit 1 of this embodiment, even if hot water is put into the container body 2 and the pressure inside the container body 2 increases, it is possible to prevent the cover 9 from forcefully rotating toward the open position due to the force of releasing the pressure inside the container body 2 when the lock state of the cover 9 is released.

[0155] Furthermore, in the first hinge portion 8, a first hinge bearing portion 52 is provided on the cover body 7 side, and a second hinge bearing portion 53 and a third hinge bearing portion 54 are provided on the cover body 9 side. However, this structure is not limited to this one; it can also be configured such that the first hinge bearing portion 52 is provided on the cover body 9 side, and the second hinge bearing portion 53 and the third hinge bearing portion 54 are provided on the cover body 7 side. Additionally, in the first hinge portion 8, the structure on the second hinge bearing portion 53 side and the structure on the third hinge bearing portion 54 side can be interchanged.

[0156] In addition, the damping box 60 can also be like Figure 29 The diagram shows a structure in which the rotary damper 59 is integrally mounted with the cover body 7. In this case, the following structure is sufficient: the first gear 57 is mounted on the second hinge bearing portion 53, and the damping box 60, which maintains engagement with the first gear 57 and the rotary damper 59, is integrally mounted with the first hinge bearing portion 52.

[0157] As described above, in the cover unit 1 of this embodiment, the second force-applying member 46 is rotatably mounted in the cover locking mechanism 36 via the second hinge portion 37. Therefore, in the cover locking mechanism 36, the second force-applying member 46 can be stably positioned between the second arm portion 38b of the locking member 38 and the peripheral wall portion 7a of the cover body 7 to prevent it from falling off. Furthermore, since it does not fall off during assembly, assembly is easy. Moreover, after assembly, it will not fall off even when force is applied from the outside.

[0158] Furthermore, in the cover locking mechanism 36, the second force-applying member 46 and the locking member 38 can be rotatably mounted together on the second hinge portion 37 while the second force-applying member 46 and the locking member 38 are integrally installed. Thus, in the cover locking mechanism 36, the second force-applying member 46 can be easily and stably positioned between the second arm portion 38b of the locking member 38 and the peripheral wall portion 7a of the cover body 7.

[0159] Furthermore, in the lid locking mechanism 36, the second force-applying member 46 is arranged to fill the gap between the second arm 38b formed in the locking member 38 and the peripheral wall 7a of the lid body 7. This prevents water, dust, and other contaminants from entering and remaining in such a gap during cleaning, thus improving hygiene.

[0160] Furthermore, since the second force-applying component 46 is composed of the aforementioned elastic component, it can be molded in a colored state, making it easier to color compared to metal spring components, and offering a wider range of color choices. Therefore, when the second force-applying component 46 is made to the same color as the cover body 7 and the locking component 38, it can be made inconspicuous in appearance. On the other hand, when the second force-applying component 46 is made to a different color, it can add embellishment to the appearance design.

[0161] Furthermore, in the cover locking mechanism 36, a metal cover member 49 covering the aforementioned locking member 38 is rotatably mounted via the second hinge portion 37. Thus, in the cover locking mechanism 36, the locking member 38 can be protected by the cover member 49, and the support strength of the locking member 38 when rotatably supported by the second hinge portion 37 can be improved.

[0162] Therefore, in the cover locking mechanism 36, by covering the locking member 38 with a metal cover member 49, the locking member 38 can be reduced in size to a size that would otherwise break due to insufficient strength. Furthermore, by typically giving the resin locking member 38 a metallic appearance, flow marks and other defects from the molding process can be further concealed. This not only improves the appearance of the locking member 38 but also balances its durability and aesthetic design.

[0163] Furthermore, when the locking member 38 is made of metal instead of the metal cover member 49, the metal hook portion 44 slides in contact with the resin hook receiving portion 45. In this case, depending on the material of the cover 9, the weaker hook receiving portion 45 may wear down due to repeated use. Additionally, making the locking member 38 of metal not only increases the cost of processing and materials due to its complex shape, but also increases its weight. In contrast, the cover member 49, due to its thinner sheet metal, can be manufactured at low cost through sheet metal stamping, whether by casting or machining.

[0164] As described above, in the cover unit 1 of this embodiment, a cover locking mechanism 36 with high functionality and excellent appearance design can be obtained.

[0165] In addition, in the cover unit 1 of this embodiment, a rotation damping mechanism 51 is provided to reduce the rotation speed of the cover 9 that rotates under the force of the first force-applying member 26, thereby preventing the cover 9 from rotating forcefully in the opening direction when the cover locking mechanism 36 releases the locking state of the cover 9.

[0166] Therefore, in the lid unit 1 of this embodiment, when the lid 9 is rotated in the opening direction, it is possible to prevent beverages and condensed water droplets adhering to the inside of the lid 9 (especially the sealing member 27) from splashing outwards. Furthermore, it is possible to prevent the lid 9 from rotating in the closing direction due to the reaction force of its rebound after being forcefully rotated in the opening direction. In addition, the lid 9 rotates in the opening direction at a substantially constant speed, thus providing a comfortable user experience.

[0167] Furthermore, in the cover unit 1 of this embodiment, the wear generated between the first hinge bearing portion 52 and the second hinge bearing portion 53 and the third hinge bearing portion 54 can be suppressed to a low level, thereby improving the durability of the first hinge portion 8.

[0168] Furthermore, in the cover unit 1 of this embodiment, the first gear 57, the second gear 58, and the rotational damper 59 are all disposed inside the damping box 60, so they cannot be seen from the outside, thus providing a good aesthetic appearance. In addition, it can prevent small foreign objects from entering the meshing part of the first gear 57 and the second gear 58 and deteriorating the damping function.

[0169] Therefore, by providing such a lid unit 1, the ease of use of the lid container 100 in this embodiment can be further improved.

[0170] 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.

[0171] For example, in the above embodiments, the present invention is illustrated in a beverage container having heat preservation or cold preservation function through a container body 2 having the above-described vacuum insulation structure. However, the present invention can be widely applied to lidded containers that have a container body and a lid unit that can be easily installed on the container body.
