DETAILED DESCRIPTION

[0034] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0035] (First Embodiment)

[0036] First, as a first embodiment of the present invention, for example, Figure 1 to Figure 4 The lidded container 100 of the lid unit 1A shown will be described.

[0037] in addition, Figure 1 The diagram shows the structure of a lidded container 100 including a lid unit 1A, and is a cross-sectional view showing a state where a lid body 9 is in a closed position. Figure 2 The structure of the covered container 100 including the cover unit 1A is shown, and it is a side view showing a state where the cover body 9 is in the open position. Figure 3The diagram shows the structure of a container 100 with a lid including a lid unit 1A, and is a perspective view showing a state where a lid body 9 is in an open position. Figure 4 The structure of the cover unit 1A is shown, and the cover body 9 is in the closed position. Figure 1 Cross-sectional views of different surfaces.

[0038] like Figure 1 to Figure 4 As shown in FIG. 1 , a container 100 with a lid according to the present embodiment includes a lid unit 1A according to the present embodiment and a container body 2 to which the lid unit 1A is detachably attached.

[0039] The container with a lid 100 is a beverage container that can keep a beverage (liquid) contained in the container body 2 warm or cold by using the container body 2 having a vacuum heat-insulating structure.

[0040] Specifically, the container body 2 is composed of a double-layer container, which has an outer container 3 with a bottom and a cylindrical shape, for example, made of stainless steel, and an inner container 4, and is formed by joining the opening edges of each other while the inner container 4 is accommodated inside the outer container 3.

[0041] 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 by, for example, blocking the exhaust hole provided on the bottom surface of the outer container 3 in a chamber decompressed (evacuated) to a high vacuum.

[0042] The container body 2 has a substantially circular bottom 2a, a barrel portion 2b substantially cylindrically rising from the outer periphery of the bottom 2a, and a substantially cylindrical neck portion 2c having a reduced diameter at the upper side of the barrel portion 2b.

[0043] The upper end of the neck portion 2c opens in a circular shape as the upper opening 2d of the container body 2. The inner circumference of the neck portion 2c is reduced in diameter compared to the inner circumference of the barrel portion 2b. An external thread portion 6 is provided on the outer circumference of the neck portion 2c.

[0044] The lidded container 100 of the present embodiment has a generally cylindrical appearance as a whole, but the appearance of the lidded container 100 is not particularly limited and can be appropriately modified according to size, design, etc. In addition, the outer peripheral surface of the container body 2 may be painted, printed, etc.

[0045] The cap unit 1A of the present embodiment includes a cap body 7 that closes the upper opening 2 d of the container body 2 , and a cap body 9 that is rotatably attached to the cap body 7 via a first hinge portion 8 .

[0046] In addition, in the following description, the side on which the cover body 9 is installed on the cover main body 7 via the first hinge portion 8 is set as the "rear side (back side)" of the cover unit 1A (container with cover 100), and the opposite side is set as the "front side (front side)" of the cover unit 1A (container with cover 100).

[0047] The cover body 7 is made of, for example, a heat-resistant resin and comprises: a peripheral wall portion 7a, which is formed in a roughly cylindrical shape in a manner continuous with the barrel portion 2b of the container body 2 and covers the outer peripheral side over the entire circumference; an upper wall portion 7b, which covers the upper portion of the peripheral wall portion 7a and is provided with a liquid passage 10 and an air vent 11 connected to the inner side of the container body 2; and an inner wall portion 7c, which protrudes in a roughly cylindrical shape from the lower surface of the upper wall portion 7b in a manner embedded in the inner side of the container body 2 from the upper opening portion 2d.

[0048] The inner peripheral surface of the peripheral wall 7a is provided with an internal thread 12 that is screwed with the external thread 6 of the container body 2. Thus, the cap body 7 is screwed and detachably mounted on the outer side of the neck opening 2c while covering the upper opening 2d of the container body 2.

[0049] The liquid passage 10 is constituted by a nozzle portion which is located on the front side of the upper wall portion 7b relative to the first hinge portion 8 and protrudes upward in a substantially cylindrical shape while penetrating the upper wall portion 7b in the up-down direction.

[0050] The vent 11 is a circular hole located between the liquid passage 10 of the upper wall 7b and the first hinge 8 and vertically penetrates the upper wall 7b. The vent 11 has a smaller opening area than the liquid passage 10.

[0051] A water-stop packing 13 is detachably mounted on the lower surface of the inner side of the cover body 7. The water-stop packing 13 is a sealing member for sealing (water-stopping) the space between the container body 2 and the cover body 7, and is composed of, for example, heat-resistant rubber such as silicone rubber, or an elastic member such as an elastomer.

[0052] The water stop packing 13 has a stepped shape along the lower surface of the upper wall portion 7b, the outer peripheral surface of the inner wall portion 7c, and the lower end surface, and is formed into a circular ring shape as a whole. The water stop packing 13 contacts the lower surface of the upper wall portion 7b and the outer peripheral surface of the inner wall portion 7c, is slightly separated from the lower end surface of the inner wall portion 7c, and is embedded in the lower surface of the inner side of the cover body 7 in a state of covering from below.

[0053] On the other hand, the waterproof packing 13 can be removed from the lower surface of the inner side of the cover body 7 by elastically deforming (stretching and elongating) itself. Thus, the waterproof packing 13 and the cover body 7 can be cleaned separately, and the space between the waterproof packing 13 and the cover body 7 can be kept clean.

[0054] In addition, an elastic flange portion 13a is provided at the upper end of the water stop packing 13, and the elastic flange portion 13a protrudes all around in the direction of the diameter expansion. When the cover body 7 is installed in the container body 2, the water stop packing 13 is in a state where the elastic flange portion 13a is elastically deformed, and the upper surface side is in close contact with the lower surface of the upper wall portion 7b all around, and the lower surface side is in close contact with the upper end of the neck opening portion 2c all around. Thus, the cover body 7 and the container body 2 can be sealed liquid-tightly (water stop).

[0055] The cover body 9 is made of, for example, a heat-resistant resin and has: a peripheral wall portion 9a formed in a substantially cylindrical shape in a manner continuous with the peripheral wall portion 7a of the cover body 7 (the outer peripheral surface of the cover body 7); and a top wall portion 9b covering the top surface of the peripheral wall portion 9a.

[0056] The first hinge portion 8 is located at the rear end portion between the peripheral wall portion 7a and the upper wall portion 7b of the cover body 7. The cover body 9 is installed to be freely rotatable between a position of closing the liquid port 10 and the vent 11 (hereinafter referred to as the "closed position") and a position of opening the liquid port 10 and the vent 11 (hereinafter referred to as the "open position") via the first hinge portion 8.

[0057] The cover packing 14 is located on the lower surface of the inner side of the cover body 9 and is detachably mounted on the lower surface of the inner side of the cover body 9. The cover packing 14 is a sealing member for sealing the cover body 7 and the cover body 9 and is composed of an elastic member of the same material as the waterproof packing 13.

[0058] The cap packing 14 includes a liquid-passing plug portion 14 a that closes the liquid-passing port 10 and a vent plug portion 14 b that closes the vent port 11 .

[0059] like Figure 1 as well as Figure 3 As shown, the liquid plug portion 14a is provided to protrude downward in a dome shape from the lower surface of the front side of the cover packing 14. The vent plug portion 14b is provided to protrude downward in a bottomed elliptical cylinder shape from the lower surface of the rear side of the cover packing 14.

[0060] The cover packing 14 has a fitting protrusion 14 c that fits into the hole 9 c provided in the cover body 9 , and a vent fitting portion 14 d that fits into the cylindrical wall portion 9 d provided in the cover body 9 .

[0061] The hole portion 9c is provided so as to penetrate the front side of the top wall portion 9b in a generally cylindrical shape in the vertical direction. The fitting protrusion 14c is provided so as to protrude upward in a generally cylindrical shape from the upper surface on the side opposite to the liquid plug portion 14a, which is the front side of the cover packing 14. The cylinder wall portion 9d is provided so as to protrude downward in an elliptical cylindrical shape from the lower surface on the rear side of the top wall portion 9b. The ventilation fitting portion 14d is provided so as to protrude upward in a manner such that the inner side of the ventilation plug portion 14b is recessed from the upper surface on the side opposite to the ventilation plug portion 14b, which is the rear side of the cover packing 14.

[0062] The cover packing 14 is mounted on the lower surface of the inner side of the cover body 9 in a state where the fitting convex portion 14c is fitted into the hole portion 9c and the tube wall portion 9d is fitted into the ventilation fitting portion 14d. In addition, in the present embodiment, the tube wall portion 9d is configured to be fitted into the inner side of the ventilation fitting portion 14d, but the ventilation fitting portion 14d may be configured to be fitted into the inner side of the tube wall portion 9d. That is, it is sufficient as long as the cover body 9 and the cover packing 14 are configured to be integrated by fitting.

[0063] Here, even when the cover body 9 is in the closed position, the engaging protrusion 14c can be visually observed from the upper surface side of the cover body 9. Therefore, regardless of the case where the cover body 9 is in the open position, it is possible to visually confirm that the cover packing 14 is installed on the cover body 9, so that the cover packing 14 will not be forgotten.

[0064] On the other hand, by removing the cover packing 14 from the lower surface inside the cover body 9 , the cover packing 14 and the cover body 9 can be cleaned separately, so that the space between the cover packing 14 and the cover body 9 can be kept hygienic.

[0065] In addition, the cover packing 14 is a structure that is detachably mounted on the above-mentioned cover body 9, but it is not limited to such a structure. For example, it can also be a structure in which the cover packing 14 is integrally mounted on the cover body 9. In this case, the cover packing 14 is integrated in a manner that does not provide a gap between the cover body 9 and the cover packing 14, so that water and the like do not enter between the cover packing 14 and the cover body 9, and hygiene can be maintained.

[0066] In the cap unit 1A of the present embodiment, when the cap body 9 closes the upper portion of the cap main body 7, the liquid plug portion 14a closes the liquid port 10 while being elastically deformed and in close contact with the periphery of the upper portion of the liquid port 10, and the vent plug portion 14b closes the vent port 11 while being elastically deformed and in close contact with the periphery of the vent port 11. Thus, the cap main body 7 and the cap body 9 can be sealed via the cap packing 14.

[0067] The cover body 7 has a sealing surface 7d which is in close contact with the vent plug portion 14b when the vent plug portion 14b closes the vent port 11, and a vent protrusion 7e which is formed by shrinking the diameter and protruding upward from the upper surface of the upper wall portion 7b (cover body 7). The sealing surface 7d is formed as a flat surface on the upper surface of the vent protrusion 7e.

[0068] like Figure 1 As shown in the figure, the vent 11 is arranged to be offset to the side (front side) opposite to the first hinge 8 of the sealing surface 7d and the vent convex portion 7e. The vent 11 is arranged at a position overlapping with the front side of the front end portion of the barrel wall portion 9d when viewed from above when the vent plug portion 14b is in close contact with the sealing surface 7d. In addition, when the vent plug portion 14b is in close contact with the sealing surface 7d, the inner peripheral side of the front end portion of the barrel wall portion 9d is located on the inner side of the sealing surface 7d in the front-rear direction when viewed from above.

[0069] Thus, the vent plug portion 14 b is strongly pressed downward toward the vent opening 11 by the front side of the front end portion of the tube wall portion 9 d , and the vent opening 11 can be reliably closed.

[0070] In addition, the sealing surface 7d and the ventilation protrusion 7e have a length in the front-to-back direction that is more than three times the front-to-back width of the vent 11. For example, in the trial production stage, it is possible to manufacture a trial product in which the vent 11 is located at a position offset to the front side, a central position, and a position offset to the rear side relative to the sealing surface 7d and the ventilation protrusion 7e without overlapping the positions of the vent 11.

[0071] Thus, a trial product can be manufactured in which only the position of the vent 11 is changed without changing the close contact state of the vent plug portion 14b relative to the entire sealing surface 7d, and the closed state of the vent 11 can be confirmed. In addition, it is easy to make adjustments when the closed state of the vent 11 is not in good condition, thereby reducing development costs.

[0072] The first hinge portion 8 is provided with a first urging member (not shown) that urges the cover body 9 toward one side in a rotation direction (hereinafter referred to as “opening direction”).

[0073] The first urging member is constituted by a spring member such as a torsion spring, for example, and is attached to the inner side of the first hinge portion 8 .

[0074] The first biasing member is not limited to the spring member described above, and may be, for example, an annular elastic member made of rubber, elastomer, etc., hung between the cover body 7 and the cover body 9 to bias the cover body 9 in the opening direction.

[0075] The cover unit 1A of the present embodiment includes a cover locking mechanism 15 that fixes the cover body 9 rotated toward the other side of the rotation direction (hereinafter referred to as “closing direction”) to the cover main body 7 against the urging force of the first urging member.

[0076] The cover lock mechanism 15 includes a lock member 17 rotatably mounted to the cover body 7 via a second hinge portion 16 and an annular stopper 18 .

[0077] The locking member 17 is rotatably supported by the second hinge portion 16 provided on the front side of the cover body 7 (the peripheral wall portion 7a). The locking member 17 includes a first arm portion 17a extending upward from the second hinge portion 16 and a second arm portion 17b extending downward from the second hinge portion 16.

[0078] A hook portion 19 is provided at a front end of the first arm portion 17 a (an upper end of the locking member 17 ) so as to protrude rearward.

[0079] A second urging member 20 made of a spring member such as a coil spring is disposed between the second arm portion 17b and the peripheral wall portion 7a. The second urging member 20 may be an elastic member such as rubber or an elastomer instead of the spring member described above.

[0080] The annular stopper 18 is composed of a partially open annular member, and both ends thereof are rotatably supported outside the second hinge portion 16. Thus, the annular stopper 18 can rotate in the up-down direction.

[0081] On the other hand, the cover lock mechanism 15 includes a lock receiving portion 21 on which the hook portion 19 of the lock member 17 is locked, and a stopper receiving portion 22 on which the annular stopper 18 is hooked.

[0082] The lock receiving portion 21 is composed of a claw portion protruding forward from the lower end of the front side of the cover body 9 (peripheral wall portion 9a). The stopper receiving portion 22 is composed of a wall portion protruding forward from a position surrounding the lock receiving portion (claw portion) 21 in a shape corresponding to the inner side of the annular stopper 18.

[0083] In the lid lock mechanism 15 , when the lid 9 closes the upper portion of the lid body 7 , the hook 19 of the lock member 17 is locked to the lock receiving portion 21 , thereby maintaining the state (closed position) in which the lid 9 closes the upper portion of the lid body 7 .

[0084] From this state, the second arm 17b side of the lock member 17 is pressed against the biasing force of the second biasing member 20, thereby releasing the locking state of the hook 19 relative to the lock receiving portion 21. Thus, the cover body 9 biased by the first biasing member is rotated in the opening direction to reach the open position.

[0085] On the other hand, in the cover locking mechanism 15, when the cover body 9 closes the upper part of the cover main body 7, the annular stopper 18 is caught on the stopper receiving portion 22, thereby preventing the cover body 9 from rotating in the opening direction. Thus, in the cover locking mechanism 15, it is possible to prevent the cover body 9 from opening due to unnecessary (accidental) operation of the locking member 17.

[0086] However, in the cover unit 1A of the present embodiment, as Figure 1 as well as Figure 4 As shown, the center of the hinge shaft 8a of the first hinge part 8 is located below the upper wall part 7b of the cover body 7. In addition, the center of the hinge shaft 8a of the first hinge part 8 is located outside the outermost diameter of the lower end of the peripheral wall part 7a of the cover body 7.

[0087] Specifically, if Figure 1 As shown, the upper wall portion 7 b of the cover body 7 is provided so that a portion on the front side of the liquid passage 10 is slightly lower than a portion on the rear side of the liquid passage 10 .

[0088] Therefore, in the cover unit 1A of the present embodiment, it is easy to set the length (height) of the nozzle portion of the liquid through port 10 protruding from the upper wall portion 7b to be longer (higher) on the front side, so that when the container body 2 is tilted and the beverage in the container body 2 flowing out from the liquid through port 10 is drunk, the lower lip and chin will not hit the upper wall portion 7b, thereby providing a good user experience.

[0089] In addition, the upper wall portion 7b of the cover body 7 is inclined so as to gradually become lower in the rear than the liquid passage 10, and a ventilation protrusion 7e is formed in the rear of the central portion, and a first hinge portion 8 is further provided so as to extend rearward from the rear end side thereof. That is, the first hinge portion 8 is configured to protrude from the side surface of the rear side of the cover body 7.

[0090] Specifically, if Figure 1 As shown, the center of the hinge shaft 8a of the first hinge part 8 is located at a position lower than the highest position of the upper wall part 7b on the rear side of the liquid passage 10. More specifically, the center of the hinge shaft 8a of the first hinge part 8 is located at a position lower than the highest position of the lower end (root) of the liquid passage 10 rising from the upper wall part 7b.

[0091] In addition, the peripheral wall portion 7a of the cap body 7 is formed to be continuous with the barrel portion 2b of the container body 2, so that the lower end side becomes the outermost diameter portion extending outward to the same diameter as the barrel portion 2b. The center portion of the hinge axis 8a of the first hinge portion 8 is located at a position outside the outermost diameter portion of the peripheral wall portion 7a.

[0092] Thus, in the cover unit 1A of the present embodiment, the first hinge portion 8 is separated from the upper surface of the cover body 7 toward the rear side of the cover body 7, and the cover body 9 is rotated to Figure 2 In the open position shown, the cover body 9 can be largely rotated toward the side surface on the rear side of the cover body 7 .

[0093] Therefore, in the covered container 100 having the cover unit 1A of the present embodiment, when the beverage in the container body 2 flowing out from the liquid outlet 10 is drunk while the container body 2 is tilted, the first hinge part 8 is positioned away from the drinker's nose, the first hinge part 8 and the cover body 9 do not touch the nose, and the first hinge part 8 and the cover body 9 do not become an obstacle, thereby achieving further improvement in ease of use.

[0094] In addition, if Figure 3 as well as Figure 4 As shown, the cover unit 1A of this embodiment is configured such that when the cover 9 is displaced forward due to an impact such as being dropped, the contact portion 9e provided on the cover 9 side contacts the contacted portion 7f provided on the cover body 7 side.

[0095] Specifically, in this embodiment, the contact portion 9e is formed by a pair of bearing portions 8b on the cover body 9 side constituting the first hinge portion 8. On the other hand, the contacted portion 7f is formed by a wall portion on the rear side of the cover body 7 facing the pair of bearing portions 8b.

[0096] In the covered container 100 having the cover unit 1A of the present embodiment, when impact is received from the first hinge 8 side (rear side) due to, for example, falling, the cover body 9 is displaced toward the front side, and the abutment portion 9e of the cover body 9 abuts against the abutted portion 7f of the cover body 7 from the rear side.

[0097] Thus, the impact is received and the further displacement of the cover body 9 toward the front side can be suppressed. In addition, the displacement amount of the cover body 9 toward the front side can be suppressed to be small, so that the lock state of the cover body 9 by the cover locking mechanism 15 can be suppressed from being accidentally released. In addition, the positional displacement of the hinge shaft 8a and the bearing part 8b is unlikely to occur due to the load applied to the first hinge part 8, and damage to the first hinge part 8 and the cover body 9 such as bending of the hinge shaft 8a can be prevented.

[0098] (Second Embodiment)

[0099] Next, as a second embodiment of the present invention, for example, Figure 5 to Figure 7 The cover unit 1B shown will be described.

[0100] in addition, Figure 5 The diagram shows the structure of the covered container 100 including the cover unit 1B, and is a cross-sectional view showing a state where the cover body 9 is in a closed position. Figure 6The diagram shows the structure of the covered container 100 including the cover unit 1B, and is a side view showing a state where the cover body 9 is in an open position. Figure 7 The structure of the cover unit 1B is shown, and the cover body 9 is in the closed position. Figure 5 In the following description, description of the same parts as those of the cover unit 1A will be omitted, and the same reference numerals will be given in the drawings.

[0101] like Figure 5 to Figure 7 As shown, the cover unit 1B of the present embodiment has basically the same structure as the cover unit 1A except that the arrangement of the first hinge portion 8 in the structure of the cover unit 1A is different.

[0102] Specifically, in the cover unit 1B of this embodiment, the first hinge portion 8 is as follows: Figure 5 to Figure 7 The side surface located at the rear side of the cover body 7 is shown.

[0103] The center of the hinge shaft 8a of the first hinge part 8 is located below the upper wall part 7b of the cover body 7. The center of the hinge shaft 8a of the first hinge part 8 is located outside the outermost diameter of the lower end of the peripheral wall part 7a of the cover body 7.

[0104] Specifically, if Figure 5 As shown in the figure, the portion of the upper wall portion 7b of the cover body 7 that is closer to the rear side than the liquid passage 10 is inclined so as to gradually become lower in the rear direction, and a ventilating convex portion 7e is formed in the rear side of the central portion. In addition, at the rear end side of the cover body 7, the first hinge portion 8 is formed by sinking one step from the rear end side of the upper wall portion 7b and extending to the rear. That is, the first hinge portion 8 is configured to protrude from the side surface of the rear side of the cover body 7.

[0105] In addition, if Figure 5 As shown, the center of the hinge shaft 8a of the first hinge part 8 is located below the lowest position of the upper wall part 7b. In addition, when the cover unit 1B (cover body 7) is installed in the container body 2, the center of the hinge shaft 8a of the first hinge part 8 is located below the upper opening 2d of the container body 2.

[0106] In addition, the peripheral wall portion 7a of the cap body 7 is formed to be continuous with the barrel portion 2b of the container body 2, so that the lower end side becomes the outermost diameter portion extending outward to the same diameter as the barrel portion 2b. The center portion of the hinge axis 8a of the first hinge portion 8 is located at a position outside the outermost diameter portion of the peripheral wall portion 7a.

[0107] Thus, in the cover unit 1B of the present embodiment, the first hinge portion 8 is separated from the upper surface of the cover body 7 toward the lower side of the rear side of the cover body 7, and the cover body 9 is rotated to Figure 6In the open position shown, the cover body 9 can be largely rotated toward the side surface on the rear side of the cover body 7 .

[0108] Therefore, in the covered container 100 having the cover unit 1B of the present embodiment, when the beverage in the container body 2 flowing out from the liquid passage 10 is drunk while the container body 2 is tilted, the first hinge part 8 is positioned away from the drinker's nose, the first hinge part 8 and the cover body 9 do not touch the nose, and the first hinge part 8 and the cover body 9 do not become an obstacle, thereby achieving further improvement in ease of use.

[0109] In addition, in the cover unit 1B of the present embodiment, the first hinge portion 8 is located on the side surface on the rear side of the cover body 7, so that when the cover body 9 is impacted from the first hinge portion 8 side (rear side) due to, for example, falling, the above-mentioned cover body 9 is displaced to the front side, and the abutting portion 9e of the cover body 9 abuts against the abutted portion 7f of the cover body 7 from the rear side.

[0110] Thus, the impact is received and the further displacement of the cover body 9 toward the front side can be suppressed. In addition, the displacement amount of the cover body 9 toward the front side can be suppressed to be small, so that the lock state of the cover body 9 by the cover locking mechanism 15 can be suppressed from being accidentally released. In addition, the positional displacement of the hinge shaft 8a and the bearing part 8b is unlikely to occur due to the load applied to the first hinge part 8, and damage to the first hinge part 8 and the cover body 9 such as bending of the hinge shaft 8a can be prevented.

[0111] In addition, the present invention is not necessarily limited to the above-described embodiment, and various modifications can be added without departing from the gist of the present invention.

[0112] For example, in the above-mentioned embodiment, the present invention is illustrated as being applied to a beverage container having heat preservation and cold preservation functions by means of a container body 2 having the above-mentioned vacuum insulation structure, but the present invention can be widely applied to a lidded container having a container body and a lid unit that is detachably mounted on the container body.
