Description

Technical Field

[0001] The invention relates to a cover unit and a container with a cover. Background Art

[0002] Conventionally, there is a container with a lid which includes a lid unit detachably attached to a container body having an upper opening (for example, refer to Patent Document 1 listed below).

[0003] The cover unit comprises: a cover body, which closes the upper opening of the container body and is provided with a liquid through hole and a vent hole connected to the inner side of the container body at the upper part; a cover body, which is rotatably mounted on the cover body via a hinge part; and a cover packing, which is detachably mounted on the inner side of the cover body and is provided with a liquid through plug part for closing the liquid through hole and a vent plug part for closing the vent hole.

[0004] The cover unit includes a cover locking mechanism that fixes the cover body, which is urged by an urging member provided on the hinge portion in a direction to open the liquid port and the vent port, to the cover body at a position where the liquid port and the vent port are closed by the liquid stopper and the vent stopper.

[0005] In the covered container having such a cover unit, by releasing the cover body fixed by the cover locking mechanism, the cover body is turned by the force of the force applying member while opening the liquid passage and the air vent, thereby making it possible to drink or pour out the beverage in the container body.

[0006] Patent Document 1: Japanese Patent Application Publication No. 2023-22743

[0007] However, in the lidded container having the above-mentioned conventional lid unit, when the beverage in the container body is drunk, the pressure in the container body temporarily becomes negative pressure as the volume of the beverage in the container body decreases. At this time, the external air is introduced into the interior of the container body through the vent provided at the upper part of the lid body. As a result, the pressure in the container body is restored to the atmospheric pressure, so that the beverage can flow out stably from the liquid passage.

[0008] On the other hand, in order to prevent the beverage in the container body from leaking out from the liquid port and the vent port, after the lid body seals the upper portion of the lid body, the liquid port and the vent port are sealed by the liquid plug and the vent plug of the lid packing.

[0009] In addition, since the vent opening has a smaller opening area than the liquid passage, a sealing portion is provided on the upper surface of the cap body, and the vent opening located in the center of the sealing portion is closed by a vent plug portion in close contact with the sealing portion.

[0010] However, in the conventional cap unit, the distance between the liquid through hole and the vent hole in the upper surface of the cap body is different according to the size of the container body. Therefore, in order to seal the liquid through hole and the vent hole under the best conditions for each size of the container body, it is necessary to prepare a cap packing with different distances between the liquid through plug part and the vent plug part, and the current situation is that it is impossible to share the parts.

[0011] In addition, in the conventional cover unit, the sealing portion having the vent hole in the center is arranged to protrude upward and is thinner than the surrounding portion. Therefore, when the resin cover unit is molded, the fluidity of the resin deteriorates and there is a possibility that the sealing portion cannot be molded into a predetermined shape. Summary of the invention

[0012] The present invention is proposed in view of the existing situation, and its purpose is to provide a cover unit that can realize the commonality of cover packings, stabilize the size and formability of the sealing part, and appropriately seal the liquid port and the air vent by the cover packing, and a covered container that can further improve the ease of use by having such a cover unit.

DETAILED DESCRIPTION

[0044] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0045] (First Embodiment)

[0046] First, as a first embodiment of the present invention, for example, Figure 1 and Figure 2 A lidded container 100A of the lid unit 1A shown will be described.

[0047] also, Figure 1 It is a cross-sectional view showing a state where the lid 9 is closed in the lid-attached container 100A including the lid unit 1A. Figure 2 It is a perspective view showing a state in which the liquid passage port 10 and the air vent port 11 of the cap unit 1A are opened.

[0048] like Figure 1 and Figure 2 As shown in FIG. 1 , a container with a cover 100A according to the present embodiment includes a cover unit 1A according to the present embodiment and a container body 2A to which the cover unit 1A is detachably attached.

[0049] The container with a lid 100A is a beverage container that can keep a beverage (liquid) contained in the container body 2A warm or cold by using the container body 2A having a vacuum heat-insulating structure.

[0050] Specifically, the container body 2A 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.

[0051] 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 exhaust holes provided on the bottom surface of the outer container 3 in a chamber decompressed (evacuated) to a high vacuum.

[0052] The container body 2A 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 whose diameter is reduced at the upper side of the barrel portion 2b.

[0053] The upper end of the neck portion 2c is opened in a circular shape as the upper opening 2d of the container body 2A. In addition, the inner circumference of the neck portion 2c is reduced in diameter compared with the inner circumference of the barrel portion 2b. In addition, an external thread portion 6 is provided on the outer circumference of the neck portion 2c.

[0054] The lidded container 100A of the present embodiment has a generally cylindrical appearance as a whole, but the appearance of the lidded container 100A is not particularly limited and can be appropriately modified according to size, design, etc. In addition, the outer peripheral surface of the container body 2A may be painted, printed, etc.

[0055] The cap unit 1A of the present embodiment includes a cap body 7 that closes the upper opening 2 d of the container body 2A and a lid body 9 that is rotatably attached to the cap body 7 via a first hinge portion 8 .

[0056] 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 100A with cover), and the opposite side is set as the "front side (front side)" of the cover unit 1A (container 100A with cover) for explanation.

[0057] 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 2A 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 that are connected to the inner side of the container body 2A; 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 2A from the upper opening portion 2d.

[0058] The inner peripheral surface of the peripheral wall 7a is provided with an internal thread 12 that is screwed with the external thread 6 on the container body 2A. 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 2A.

[0059] 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.

[0060] 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.

[0061] 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 2A and the cover body 7, and is composed of an elastic member such as heat-resistant rubber such as silicone rubber or an elastomer.

[0062] 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.

[0063] 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.

[0064] 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 2A, 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 2A can be sealed liquid-tightly (water stop).

[0065] 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.

[0066] 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.

[0067] The cover packing 14 is located on the inner lower surface of the cover body 9 and is detachably mounted on the inner lower surface 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.

[0068] 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 .

[0069] The liquid stopper 14a is provided so as to protrude downward in a dome shape from the lower surface of the front side of the cover packing 14. The vent stopper 14b is provided so as to protrude downward in a bottomed elliptical cylinder shape from the lower surface of the rear side of the cover packing 14.

[0070] The cover packing 14 includes 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 .

[0071] 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.

[0072] 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.

[0073] Here, even when the cover 9 is in the closed position, the engaging protrusion 14c can be visually observed from the upper surface side of the cover 9. Therefore, regardless of the case where the cover 9 is in the open position, it is possible to visually confirm that the cover packing 14 is installed on the cover 9, so that the cover packing 14 will not be forgotten.

[0074] 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.

[0075] In addition, the cover packing 14 is detachably mounted on the cover body 9, but is not limited to such a structure. For example, the cover packing 14 may be 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.

[0076] In the cap unit 1A of the present embodiment, when the cap body 9 closes the upper part of the cap main body 7, the liquid plug part 14a closes the liquid through hole 10 while being elastically deformed and in close contact with the upper periphery of the liquid through hole 10, and the vent plug part 14b closes the vent hole 11 while being elastically deformed and in close contact with the periphery (sealing part) of the vent hole 11. Thus, the cap main body 7 and the cap body 9 can be sealed via the cap packing 14.

[0077] like Figure 1 and Figure 2 As shown, the cover body 7 has: a sealing surface 7d, which is a sealing portion that is in close contact with the lower surface of 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 vent protrusion 7e is an elliptical shape extending in the front-to-back direction when viewed from above. The sealing surface 7d is a flat surface in the shape of an ellipse extending in the front-to-back direction on the upper surface of the vent protrusion 7e when viewed from above.

[0078] The sealing surface 7d and the vent convex portion 7e are provided so as to protrude upward from the wall portion 7b in a manner that the plate thickness of a portion of the cover body 7 increases. Therefore, the resin fluidity when the cover body 7 made of heat-resistant resin is molded is good, and the dimensions of the sealing surface 7d and the vent convex portion 7e are stable. Therefore, the vent 11 can be stably sealed.

[0079] 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. In addition, the area of ​​the lower surface of the vent plug portion 14b is larger than the sealing surface 7d in the entire circumferential direction when viewed from above, and the vent plug portion 14b abuts against and closely adheres to the sealing surface 7d while elastically deforming to cover the entire surface of the sealing surface 7d.

[0080] As a result, the lower surface of the vent plug portion 14b abuts against the sealing surface 7d in a surface contact manner, so that even if the vent 11 is set to be offset to the front side of the sealing surface 7d, the vent 11 can be stably sealed regardless of where it is located on the sealing surface 7d and the vent convex portion 7e. In addition, it is not easily affected by the error of each cavity of the mold, and the vent 11 can be stably sealed regardless of which mold is used for manufacturing.

[0081] The vent 11 is provided at a position overlapping with the front side of the front end of the tube wall portion 9d in a plan view (at the position where the vent plug portion 14b is in close contact with the sealing surface 7d). Figure 1 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 tube wall portion 9d is located inside the sealing surface 7d in the front-rear direction when viewed from above.

[0082] 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 more reliably closed.

[0083] 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, a central position, and a position offset to the rear relative to the sealing surface 7d and the ventilation protrusion 7e without overlapping the positions of the vent 11.

[0084] 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.

[0085] 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”).

[0086] 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 .

[0087] The first urging member is not limited to the above-mentioned spring member, 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 urge the cover body 9 in the opening direction.

[0088] 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.

[0089] The cover lock mechanism 15 includes a lock member 17 and an annular stopper 18 which are rotatably mounted on the cover body 7 via a second hinge portion 16 .

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] In the cover locking mechanism 15 , when the cover 9 closes the upper portion of the cover body 7 , the hook 19 of the locking member 17 is locked to the lock receiving portion 21 , thereby maintaining the state (closed position) in which the cover 9 closes the upper portion of the cover body 7 .

[0097] 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.

[0098] 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.

[0099] In the covered container 100A having the cover unit 1A of the present embodiment having the above-described structure, by providing a cover packing 14 having a liquid plug portion 14a for closing the above-mentioned liquid through port 10 and a vent plug portion 14b for closing the vent port 11, it is possible to prevent the beverage in the container body 2A from leaking to the outside through the liquid through port 10 and the vent port 11.

[0100] (Second Embodiment)

[0101] Next, as a second embodiment of the present invention, for example, Figure 3 and Figure 4 A lidded container 100B of the lid unit 1B shown will be described.

[0102] also, Figure 3 It is a cross-sectional view showing a state where the lid 9 is closed in the lid-attached container 100B including the lid unit 1B. Figure 4 It is a perspective view showing a state where the liquid passage port 10 and the air vent 11 of the cap unit 1B are opened. In the following description, description of the parts equivalent to those of the cap unit 1A is omitted, and the same reference numerals are given in the drawings.

[0103] like Figure 3 and Figure 4 As shown in FIG. 1 , a container 100B with a cover according to the present embodiment includes a cover unit 1B according to the present embodiment and a container body 2B to which the cover unit 1B is detachably attached.

[0104] The cover unit 1B of this embodiment has basically the same structure as the cover unit 1A, except that the vent 11 of the cover body 7 is provided offset to the first hinge portion 8 side (rear side) of the sealing surface 7d and the vent convex portion 7e.

[0105] On the other hand, the container body 2B has a larger capacity (size) than the container body 2A, and the diameter of the upper opening 2d of the container body 2B is larger than the diameter of the upper opening 2d of the container body 2A.

[0106] In the cap unit 1B of the present embodiment, the overall size is larger than that of the cap unit 1A in accordance with the difference in size between the container body 2B and the container body 2A. However, although the position of the vent 11 in the cap body 7 is different, the size of the sealing surface 7d and the vent convex portion 7e are the same in the cap units 1A and 1B, and the same cap packing 14 is used. Therefore, in the cap unit 1B, as in the cap unit 1A, the vent plug portion 14b abuts against and closely adheres to the sealing surface 7d while elastically deforming so as to cover the entire surface.

[0107] In addition, in the cover unit 1B of the present embodiment, since the lower surface of the vent plug portion 14b is in surface contact with the sealing surface 7d, it also includes the case where the vent 11 is set to be offset to the rear side of the sealing surface 7d. Regardless of the position of the vent 11 on the sealing surface 7d and the vent protrusion 7e, it can be stably closed.

[0108] The vent 11 is provided at a position overlapping with the rear side of the front end of the tube wall portion 9d in a plan view when the vent plug portion 14b is in close contact with the sealing surface 7d (at a position where the vent plug portion 14b is in close contact with the sealing surface 7d). Figure 3 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 tube wall portion 9d is located inside the sealing surface 7d in the front-rear direction when viewed from above.

[0109] Thus, the vent plug portion 14 b is strongly pressed downward against the vent opening 11 by the rear side of the front end portion of the tube wall portion 9 d , and the vent opening 11 can be more reliably closed.

[0110] In the covered container 100B having the cover unit 1B of the present embodiment having the above-described structure, by providing a cover packing 14 having a liquid plug portion 14a for closing the above-mentioned liquid through port 10 and a vent plug portion 14b for closing the vent port 11, it is possible to prevent the beverage in the container body 2B from leaking to the outside through the liquid through port 10 and the vent port 11.

[0111] In addition, regarding the cover unit 1A of the first embodiment and the cover unit 1B of the second embodiment, as Figure 5 As shown, although the position of the vent 11 in the cap body 7 is different corresponding to the difference in size between the container bodies 2A and 2B, the same cap packing 14 is used.

[0112] In this case, in the cover unit 1A of the above-mentioned first embodiment, when the vent plug portion 14b is in contact and tightly attached to the sealing surface 7d, the vent plug portion 14b is strongly pressed downward against the vent port 11 by the front side of the front end portion of the tube wall portion 9d, relative to the vent port 11 which is arranged to be offset to the side (front side) opposite to the first hinge portion 8 of the sealing surface 7d.

[0113] On the other hand, in the cover unit 1B of the above-mentioned second embodiment, when the vent plug portion 14b is in contact and tightly attached to the sealing surface 7d, the vent plug portion 14b is strongly pressed downward against the vent port 11 by the rear side of the front end portion of the tube wall portion 9d, relative to the vent port 11 which is arranged to be offset toward the first hinge portion 8 side (rear side) of the sealing surface 7d.

[0114] The dimensions of the sealing surface 7d and the ventilation protrusion 7e are the same in the cover unit 1A and the cover unit 1B. Figure 5 As shown, the dimensions and positions of the sealing surface 7d, the vent convex portion 7e, and the vent plug portion 14b (cover packing 14) are completely consistent in the cover unit 1A and the cover unit 1B. In both the cover unit 1A and the cover unit 1B, the vent plug portion 14b abuts against and adheres to the sealing surface 7d in a manner that covers the entire surface while elastically deforming.

[0115] Thus, the lower surface of the vent plug portion 14b abuts against the sealing surface 7d in a surface contact manner, so even if the position of the vent hole 11 in the cover body 7 is different, the vent hole 11 can be properly sealed using the same cover packing 14 without changing the size and relative position of the vent plug portion 14b relative to the sealing surface 7d and the vent convex portion 7e. Thus, it is not necessary to prepare two cover packings 14 of different sizes, which can reduce manufacturing costs.

[0116] In the cap unit 1A of the first embodiment and the cap unit 1B of the second embodiment, when the cap body 9 closes the upper portion of the cap body 7 , the liquid plug 14 a closes the liquid port 10 while elastically deforming in close contact with the upper periphery of the liquid port 10 .

[0117] Here, in the cover unit 1A and the cover unit 1B, as shown in FIG. Figure 5 As shown in the figure, the dimensions and relative positions of the hole 9c, the liquid passage port 10, the liquid passage plug portion 14a and the fitting convex portion 14c (cover packing 14) are identical and completely consistent. That is, similarly to the sealing of the vent 11, the liquid passage port 10 can be appropriately sealed without changing the dimensions and relative positions of the hole 9c, the liquid passage port 10, the liquid passage plug portion 14a and the fitting convex portion 14c (cover packing 14).

[0118] In addition, even in the case of the structure in which the cover packing 14 is integrally mounted on the cover body 9, the above advantages are the same. That is, the same cover packing 14 can be used in the cover unit 1A and the cover unit 1B, so that, for example, in the case of insert molding, the cover packing 14 can be shared and used for molding. In addition, in the cover unit 1A and the cover unit 1B, the vent 11 and the liquid port 10 can be equally and appropriately sealed.

[0119] As described above, in the covered container 100A, 100B of the present embodiment, by having the cover units 1A, 1B that can realize the commonality of the above-mentioned cover packing 14, stabilize the size and formability of the sealing part, and appropriately seal the liquid port 10 and the air vent 11 through the cover packing 14, the ease of use can be further improved.

[0120] In addition, the present invention is not necessarily limited to the above-mentioned embodiment, and various modifications can be added within the scope not departing from the gist of the present invention.

[0121] 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 2A, 2B having the above-mentioned vacuum insulation structure, but the present invention can be widely applied to a container with a lid having a container body and a lid unit that is detachably mounted on the container body.
