Description

Technical Field

[0001] This invention relates to containers for beverages. Background Technology

[0002] Conventionally, beverage containers have included a shoulder member attached to the neck of the container body with an upper opening, and a cap unit that is detachably attached to the shoulder member (for example, see Patent Document 1 below).

[0003] However, the beverage container described in Patent Document 1 below has a sealing cap that covers the neck of the container body, thus sealing the container body and the shoulder member. This prevents the beverage inside the container body from leaking through the gap between the neck and the shoulder member.

[0004] Patent Document 1: Japanese Patent Application Publication No. 2014-31192

[0005] However, in the beverage container described in Patent Document 1, water or the like may seep into the gap between the container body and the shoulder member from the outer peripheral side during washing. In this case, since the shoulder member, which is fitted onto the neck of the container body, cannot be removed, it will not only become unsanitary due to water or the like remaining in the gap, but may also cause the container body to rust. Summary of the Invention

[0006] The present invention was made in view of the existing situation, and its object is to provide a beverage container that can keep the shoulder of the container body and the shoulder component hygienic.

Figure 14 Other structures of the shoulder filler 9B are shown in (A) as its top view, (B) as a cross-sectional view based on line segment AA shown in (A), and (C) as an enlarged cross-sectional view of the circled portion B shown in (B). Figure 15 This is a cross-sectional view showing the structure in which the mouth filling component 9A and the shoulder filling component 9B are integrally formed.

[0047] like Figure 1 As shown, the lidded container 1 of this embodiment includes a container body 2 and a lid unit 3 that is detachably mounted on the container body 2. The lidded container 1 is a tabletop pitcher (beverage container) capable of keeping the beverage (contents) contained in the container body 2 warm or cold through the container body 2 having a vacuum insulation structure.

[0048] Furthermore, in the lidded container 1 of this embodiment, the side with the injection port 15 (described later) is considered the "front side", and the side with the handle portion 8b located on the opposite side of the injection port 15 is considered the "rear side".

[0049] like Figures 1-3 As shown, the container body 2 is a double-layered container, having a bottomed cylindrical outer container 4 and an inner container 5 made of, for example, stainless steel, with their openings joined together so that the inner container 5 is housed inside the outer container 4. Furthermore, a vacuum insulation layer 6 is provided between the outer container 4 and the inner container 5. The vacuum insulation layer 6 can be formed, for example, by blocking an exhaust vent located at the center of the bottom surface of the outer container 4 within a chamber that has been depressurized (evacuated) to a high vacuum.

[0050] The container body 2 has: a generally circular bottom 2a; a generally cylindrical cylindrical body portion 2b that rises from the outer periphery of the bottom 2a; a generally cylindrical neck portion 2c that narrows at the upper side of the cylindrical body portion 2b; and a shoulder portion 2d that gradually narrows from the cylindrical body portion 2b toward the neck portion 2c. Furthermore, the upper end of the neck portion 2c has a circular opening, serving as the upper opening 2e of the container body 2. Additionally, the inner circumferential surface of the neck portion 2c is narrower than the inner circumferential surface of the cylindrical body portion 2b. Furthermore, an annular protrusion 7 is provided protruding throughout the entire circumference of the inner circumferential surface of the neck portion 2c.

[0051] Furthermore, the container body 2 of this embodiment has a generally cylindrical shape with a reduced diameter at the upper part of the cylindrical portion 2b. However, the shape of the container body 2 is not particularly limited and can be appropriately modified according to size, appearance design, etc. In addition, the outer peripheral surface of the container body 2 can be coated or printed.

[0052] The container body 2 has a structure in which a shoulder component 8 is installed at the neck 2c. The shoulder component 8 is made of resin molded from materials such as polypropylene (PP), acrylonitrile butadiene styrene (ABS), or polyacetal (POM), and is generally cylindrical in shape.

[0053] Shoulder component 8 is installed on the neck portion 2c of container body 2 via filler 9A and shoulder filler 9B. Filler 9A and shoulder filler 9B are annular sealing components that seal the neck portion 2c and shoulder portion 2d of container body 2 with shoulder component 8, and are made of elastic components such as heat-resistant rubber or elastomers.

[0054] The shoulder component 8 is fitted onto the neck portion 2c of the container body 2 in a state that covers the neck portion 2c, shoulder 2d and upper opening 2e of the container body 2 through the filling seals 9A and shoulder filling seals 9B, so as to be coplanar with the outer peripheral surface of the cylindrical portion 2b of the container body 2.

[0055] The filling seal 9A covers the upper end of the neck portion 2c, sealing the neck portion 2c of the container body 2 with the shoulder member 8. Furthermore, the inner circumference of the filling seal 9A extends to near the lower end of the inner circumference of the shoulder member 8. This prevents beverage from entering the gap between the neck portion 2c and the shoulder member 8 of the container body 2 and prevents leakage from that point.

[0056] On the other hand, such as Figure 2 or Figure 3 As shown, the shoulder seal 9B is positioned at least between the shoulder 2d and the lower surface of the shoulder member 8 opposite to the shoulder 2d, thus sealing the gap between the shoulder 2d and the shoulder member 8 of the container body 2. This prevents water or other substances from seeping into the gap between the shoulder 2d and the shoulder member 8 of the container body 2 during cleaning.

[0057] Furthermore, the shoulder member 8 has a fitting recess 8a on the surface (lower surface) opposite to the shoulder portion 2d for the shoulder filler 9B to be inserted. On the other hand, the shoulder filler 9B has at least one (four in this embodiment) elastic ribs 9a that protrude circumferentially from at least one of the surfaces (lower surface) opposite to the shoulder portion 2d and the surface (upper surface) opposite to the shoulder member 8 (upper and lower surfaces in this embodiment). The four elastic ribs 9a are located on the inner and outer circumferential sides of the upper and lower surfaces of the shoulder filler 9B, and are provided to protrude in opposite directions from mutually opposing positions.

[0058] When the shoulder filler 9B is sandwiched between the shoulder 2d and the shoulder member 8, it becomes elastically deformable with the elastic rib 9a and is in close contact with the surface that abuts against the elastic rib 9a throughout the entire circumference. Therefore, even if there are dimensional errors in the container body 2 and the shoulder member 8 due to molding conditions, the elastic rib 9a can elastically deform according to the dimensional difference, thus ensuring a seal between the shoulder 2d and the shoulder member 8.

[0059] A handle portion 8b for the user to hold is provided on the rear side of the shoulder member 8. The handle portion 8b protrudes rearward and extends downward from the outer periphery of the shoulder member 8. Furthermore, the handle portion 8b is not limited to the structure described above where it is provided on the rear side of the container body 2; it may also be provided on the rear side of the lid unit 3.

[0060] like Figures 1-9 As shown, the cover unit 3 of this embodiment includes a cover body 10, a cover body 11 located on the upper side of the cover body 10, and a middle bolt 12 located on the lower side of the cover body 10.

[0061] like Figures 2-7 As shown, the cover body 10 is made of resin molded body such as PP, ABS, POM, etc., and has a generally circular bottom wall portion 10a that is recessed upward and a generally cylindrical peripheral wall portion 10b that rises from the outer periphery of the bottom wall portion 10a.

[0062] The cap body 10 is screwed onto the shoulder member 8 (container body 2) for easy attachment and detachment. Therefore, an internal thread 13 is provided on the inner circumferential surface of the shoulder member 8. On the other hand, an external thread 14, which engages with the internal thread 13, is provided on the outer circumferential surface of the peripheral wall portion 10b (cap body 10). The cap body 10 closes the upper opening 2e of the container body 2 by being attached to the shoulder member 8 (container body 2).

[0063] Furthermore, the cover body 10 is designed to be detachably mounted relative to the shoulder member 8. However, if the structure of the shoulder member 8 is omitted, it is sufficient to use a structure in which the cover body 10 is detachably mounted to the neck 2c of the container body 2 by screwing it on.

[0064] A flow path R communicating with the inner side of the container body 2 is provided on the inner side of the cap body 10. The cap body 10 has: an inlet 15 that protrudes forward from the upper end of the front side of the peripheral wall portion 10b; a pair of partitions 16 that protrude rearward from the inner circumferential surface of the front side of the peripheral wall portion 10b; a liquid inlet 17 that is provided to open the bottom wall portion 10a between the lower sides of the pair of partitions 16; a vent 18 that is provided to open the rear side of the bottom wall portion 10a; and a sleeve portion 19 that is provided in the center of the bottom wall portion 10a.

[0065] Inlet 15 is the part that pours the beverage from the container body 2 outward, and is composed of a groove that slopes upward and protrudes forward. A pair of partitions 16 are parts that divide a portion of the flow path R along the width direction between the inlet 15 and the liquid inlet 17, and are provided parallel to each other between the inlet 15 and the liquid inlet 17. The liquid inlet 17 is the part that allows liquid to flow into the inside of the container body 2, and is composed of a hole that passes through the front side of the bottom wall 10a. The vent 18 is the part that allows air to flow into the inside of the container body 2, and is composed of a hole that passes through the rear side of the bottom wall 10a. The sleeve 19 is the part that supports the sliding shaft 30 (described later) so that it can slide freely in the vertical direction, and has a shaft hole 19a that passes through the bottom wall 10a, and is provided in a generally cylindrical shape protruding upward.

[0066] Furthermore, regarding the injection port 15, it can be located at the upper end of the front side of the cap body 10, but it can also be located at the upper end of the front side of the shoulder member 8. When the injection port 15 is located at the shoulder member 8, it is only necessary to configure it such that when the cap unit 3 is installed on the container body 2, the pair of upper wall portions 10d (described later) are continuous with the base end of the injection port 15 located at the shoulder member 8.

[0067] The upper part of the cover body 10 is provided with an upper flange portion 10c that protrudes from the upper end of the peripheral wall portion 10b in the direction of diameter expansion, and a pair of upper wall portions 10d that protrude upward from the upper surface of the upper flange portion 10c.

[0068] The upper flange portion 10c forms a stepped portion 10e throughout the entire circumference between it and the outer peripheral surface of the peripheral wall portion 10b. A pair of upper wall portions 10d are continuous with the base end of the injection port 15 and are provided to protrude rearward from the upper flange portion 10c in a manner that surrounds the upper end of the peripheral wall portion 10b.

[0069] A waterproof sealing element 20 is detachably installed on the lower part of the cap body 10. The waterproof sealing element 20 is an annular sealing component that seals the inner side of the container body 2 with the cap body 10. It is made of elastic components such as heat-resistant rubber or elastomers.

[0070] The lower part of the cover body 10 is provided with a lower peripheral wall 10f that protrudes downward from the bottom wall portion 10a in a generally cylindrical shape, and a lower flange portion 10g that protrudes from the outer periphery of the lower peripheral wall 10f and extends throughout the entire circumference in the expansion direction.

[0071] On the other hand, an annular fitting recess 20a is provided all around the inner circumference of the waterproof sealant 20. With the lower flange portion 10g fitted into the fitting recess 20a, the waterproof sealant 20 is fitted onto the outer circumferential surface of the lower peripheral wall 10f, thereby being detachably mounted onto the outer circumferential portion of the lower end side of the cover body 10.

[0072] Furthermore, an elastic flange portion 20b protruding throughout the entire circumference in the expansion direction is provided on the outer peripheral surface of the waterproof sealant 20. When the cap body 10 is installed on the container body 2, the waterproof sealant 20 becomes elastically deformed by the elastic flange portion 20b and is in close contact with the protrusion 7 of the container body 2 throughout the entire circumference. As a result, a seal can be formed between the protrusion 7 (the inner side of the container body 2) and the cap body 10.

[0073] On the other hand, the waterproof sealant 20 can be removed from the cap body 10 by elastically deforming (stretching). This allows the cap body 10 and the waterproof sealant 20 to be cleaned separately, thus maintaining hygiene between them.

[0074] Furthermore, the waterproof sealant 20 is not limited to the shape described above. For example, the number of elastic flange portions 20b is not limited to one, but can also be multiple. In addition, the shape of the elastic flange portions 20b can also be appropriately modified.

[0075] like Figures 2-6 , Figure 8 as well as Figure 10 As shown, the cover 11 is installed in a vertical direction relative to the cover body 10 under the condition that the first helical spring 21 located inside it applies force to the upward side.

[0076] Specifically, the cover 11 has a first helical spring 21, a cover component 22, a first retaining component 23, and a cover component 24. The first helical spring 21, as the first force-applying component, is made of a metal coil with excellent corrosion resistance, such as stainless steel. The cover component 22, the first retaining component 23, and the cover component 24 are made of resin molded materials such as PP, ABS, or POM.

[0077] The cover component 22 is generally formed in the shape of an elliptical plate so as to close the upper part of the peripheral wall portion 10b when it is embedded inside the pair of upper wall portions 10d of the cover body 10.

[0078] A flow path forming portion 25, forming a part of the flow path R, is provided on the front side of the cover member 22 (cover body 11). The flow path forming portion 25 has an upper wall 25a covering the upper sides of a pair of partition walls 16, a rear wall 25b covering the rear sides of a pair of partition walls 16, and a pair of side walls 25c covering the outer surfaces of a pair of partition walls 16. The pair of partition walls 16 engage with the upper wall 25a, the rear wall 25b, and the pair of side walls 25c, forming a flow path R from the liquid inlet 17 toward the injection port 15.

[0079] In addition, the cover component 22 is detachably installed relative to the cover body 10 by engaging a pair of engaging grooves 16a formed on the outer surface of a pair of partition walls 16 and a pair of engaging protrusions 25d formed on the inner surface of a pair of side walls 25c.

[0080] The first retaining member 23 has a generally circular top wall portion 23a, a generally cylindrical peripheral wall portion 23b that descends from the outer periphery of the top wall portion 23a, and a plurality of holes 23c (three in this embodiment) penetrating the top wall portion 23a.

[0081] Additionally, the first retaining member 23 has a pair of guide protrusions 26 and a sleeve portion 27. The pair of guide protrusions 26 are provided outward from opposite positions on the peripheral wall portion 23b.

[0082] The sleeve portion 27 is the part for which the sliding shaft 30, described later, can be freely installed and removed by screwing. It has a shaft hole 27a that passes through the center of the top wall portion 23a and protrudes downward in a generally cylindrical shape. In addition, a pair of screwing protrusions 27b are provided on the inner side of the sleeve portion 27 (the inner circumferential surface of the shaft hole 27a).

[0083] On the other hand, the cover component 22 is provided with a receiving recess 22a for receiving the first helical spring 21, a shaft hole 22b through the central portion of the receiving recess 22a, a pair of guiding recesses 22c for guiding a pair of guiding protrusions 26 to slide freely in the vertical direction, and a pair of abutting portions 22d that abut against a pair of guiding protrusions 26 at the upper ends of the pair of guiding recesses 22c.

[0084] The first retaining member 23 is mounted on the cover member 22 by compressing the first helical spring 21 between the receiving recess 22a and the top wall portion 23a while a pair of guide protrusions 26 enter the inside of a pair of guide recesses 22c.

[0085] Thus, the first retaining member 23 holds the first coil spring 21 in a compressed state between itself and the cover member 22. Furthermore, the first retaining member 23, under the force exerted upward by the first coil spring 21, can slide (move) freely in the vertical direction. Additionally, the sliding (movement) of the first retaining member 23 relative to the cover member 22 is restricted by the abutment of a pair of guide protrusions 26 against a pair of abutment portions 22d.

[0086] The cover member 24 is generally formed in the shape of an elliptical plate so as to cover the upper part of the cover member 22 and the first retaining member 23 when it is embedded inside the pair of upper wall portions 10d of the cover body 10. In addition, an operating lever 24a protruding rearward is provided at the rear end of the cover member 24.

[0087] The cover member 24 is mounted freely in the vertical direction via a hinge 28 provided between it and the cover member 22. The hinge 28 has a pair of engaging grooves 25e provided on the side of the cover member 22 and a pair of support shafts 24b provided on the side of the cover member 24.

[0088] A pair of engaging grooves 25e are located on the outer surfaces of a pair of side walls 25c, and are formed by cuts from the upper ends of the pair of side walls 25c toward the lower and rearward direction. A pair of support shafts 24b are provided protruding from the inner surfaces of a pair of arms 24c, which protrude downward from the lower surface of the front side of the cover member 24.

[0089] The hinge 28 supports the cover member 24 so that it can rotate freely relative to the cover member 22 by engaging a pair of pivots 24b with a pair of pivot slots 25e and positioning the pair of pivots 24b at the rear ends of the pair of pivot slots 25e. Furthermore, the cover member 24 is detachably mounted to the cover member 22 by engaging the pair of pivots 24b with the pair of pivot slots 25e constituting the hinge 28.

[0090] Furthermore, the cover member 24 has an elastic piece 24d protruding downward from its rear lower surface and a locking claw 24e protruding forward from the end of the elastic piece 24d. On the other hand, a locking hole 22e is provided at the rear opening of the cover member 22. When the elastic piece 24d is inserted into the locking hole 22e, the locking claw 24e is engaged in the locking hole 22e, thereby restricting its upward rotation (movement) relative to the cover member 22.

[0091] like Figures 2-6 as well as Figure 9 As shown, the central bolt 12 is freely movable in the vertical direction and installed on the cover body 10.

[0092] Specifically, the bolt 12 includes a bolt body 29, a sliding shaft 30, a second helical spring 31, and a second retaining member 32. The second helical spring 31, as a second force-applying member, is made of a metal coil with excellent corrosion resistance, such as stainless steel. The bolt body 29, the sliding shaft 30, and the second retaining member 32 are made of resin molded materials such as PP, ABS, or POM.

[0093] The plug body 29 is generally formed in a circular plate shape to close the lower part of the cap body 10. Additionally, the plug body 29 has an upwardly recessed shape. Furthermore, on the outer periphery of the lower surface side of the plug body 29, a pair of wall portions 29a are provided protruding downward from opposite positions for gripping during loading and unloading.

[0094] A sleeve portion 33 is provided in the center of the bolt body 29. The sleeve portion 33 is the part that supports the sliding shaft 30 and allows it to slide freely in the vertical direction. It has a central hole 33a that passes through the bolt body 29 and protrudes upward in a generally cylindrical shape. In addition, the sleeve portion 33 is disposed inside the second coil spring 31.

[0095] The sliding shaft 30 has a shaft portion 30a and a head 30b at the lower end of the shaft portion 30a. With the shaft portion 30a passing through the central hole 33a towards the upward side, it is slidably (movably) mounted on the bolt body 29 in the vertical direction. In addition, the sliding shaft 30 abuts against the lower surface of the bolt body 29 via the head 30b to limit its sliding (movement) relative to the bolt body 29 towards the upward side.

[0096] Furthermore, the sliding shaft 30 has multiple (four in this embodiment) ribs 30c protruding from the base end side of the shaft portion 30a. On the other hand, multiple (four in this embodiment) guide grooves 33b are provided on the inner side of the sleeve portion 33 (the inner circumferential surface of the central hole 33a) for engaging the multiple ribs 30c. Thus, the central bolt 12 restricts the rotation of the bolt body 29 about the shaft portion 30a (sliding shaft 30) relative to the shaft portion 30a.

[0097] Additionally, a pair of engagement grooves 30d for engaging with a pair of engagement protrusions 27b and a pair of locking grooves 30e for locking the pair of engagement protrusions 27b are provided on the outer peripheral surface of the shaft portion 30a. The pair of engagement grooves 30d are formed in a spiral cut downward from the upper end side of the shaft portion 30a. The pair of locking grooves 30e are formed continuously upward from the lower end of each engagement groove 30d.

[0098] A shaft sealing member 34 is installed on the shaft portion 30a in a way that allows for easy installation and removal. The shaft sealing member 34 is an annular sealing component that seals the shaft portion 30a (sliding shaft 30) that passes through the shaft hole 19a of the sleeve portion 19 with the shaft hole 19a (cover body 10). It is made of, for example, heat-resistant rubber such as silicone rubber, or elastic components such as elastomers.

[0099] The shaft filling member 34 is fitted into an annular fitting recess 30f provided on the outer peripheral surface of the shaft portion 30a. In addition, an elastic flange portion 34a is provided on the outer peripheral surface of the shaft filling member 34 in the diameter expansion direction, which is in close contact with the shaft hole 19a around its entire circumference.

[0100] A head sealant 35 is detachably mounted on the head 30b. The head sealant 35 is an annular sealing member that seals the area between the head 30b (sliding shaft 30) and the center hole 33a (bolt 29), which abuts against the periphery of the center hole 33a of the sleeve portion 33. It is made of, for example, a heat-resistant rubber such as silicone rubber, or an elastic component such as an elastomer. The head sealant 35 covers the outer periphery of the head 30b.

[0101] The second retaining member 32 has a generally circular top wall portion 32a, a generally cylindrical peripheral wall portion 32b that descends from the outer periphery of the top wall portion 32a, and a sliding hole 32c that passes through the center of the top wall portion 32a.

[0102] The second retaining member 32 is mounted on the sliding shaft 30 by compressing the second helical spring 31 between the bolt body 29 and the top wall portion 32a, and by having the shaft portion 30a pass through the sliding hole 32c.

[0103] In addition, the second retaining member 32 is restricted from sliding (moving) upward relative to the sliding shaft 30 by abutting against the abutting portion 30g provided between the upper ends of the plurality of ribs 30c.

[0104] Therefore, the second retaining member 32 holds the second coil spring 31 in a compressed state between itself and the bolt body 29. Furthermore, the second retaining member 32, under the force exerted upward by the second coil spring 31, slides freely in the vertical direction. Additionally, the second coil spring 31 exerts a downward force on the bolt body 29 relative to the sliding shaft 30.

[0105] Furthermore, multiple (four in this embodiment) guide grooves 32d are provided on the inner circumferential surface of the sliding hole 32c for engaging with multiple rib walls 30c. As a result, the central bolt 12 restricts the rotation of the second retaining member 32 about the shaft relative to the shaft portion 30a (sliding shaft 30).

[0106] In the cover unit 3 of this embodiment, as Figure 2 , Figure 3 , Figure 6 as well as Figure 10 As shown, the sliding shaft 30 on the side of the bolt 12 is detachably mounted on the first retaining member 23 on the side of the cover 11 by screwing it in.

[0107] Specifically, with the shaft portion 30a of the sliding shaft 30 passing through the shaft holes 19a, 22b, and 27a of the cover body 10, the cover component 22, and the first retaining component 23, and with the end portion of the shaft portion 30a protruding upward from the first retaining component 23, the sliding shaft 30 (middle bolt 12) is freely installed on the first retaining component 23 (cover body 11) by screwing it on.

[0108] While the middle bolt 12 rotates the sliding shaft 30 and the bolt body 29 together in one direction about the axis (right-handed in this embodiment), the pair of engagement protrusions 27b engage with the pair of engagement grooves 30d, and then the pair of engagement protrusions 27b are locked in the pair of locking grooves 30e, thereby enabling it to be installed on the first retaining member 23 (cover 11).

[0109] Therefore, in the cover unit 3 of this embodiment, the cover body 11 and the middle bolt 12 can be installed relative to the cover body 10. In addition, in the cover unit 3 of this embodiment, the bolt 29 is in close contact with the waterproof sealant 20 all around the circumference, thereby sealing the lower part of the cover body 10 with the bolt 29 (middle bolt 12).

[0110] On the other hand, by rotating the sliding shaft 30 and the bolt body 29 together in opposite directions around the axis (left-handed in this embodiment), the middle bolt 12 can be removed relative to the first retaining member 23 (cover body 11). Thus, in the cover unit 3 of this embodiment, the cover body 11 and the middle bolt 12 can be removed relative to the cover body 10 and disassembled.

[0111] In addition, such as Figure 11 and Figure 12 As shown, the cover unit 3 of this embodiment includes a stop mechanism 36, which restricts the bolt 29 (middle bolt 12) from rotating about an axis relative to the cover body 10 when the bolt 29 (middle bolt 12) is closed on the lower side of the cover body 10.

[0112] The stop mechanism 36 has at least one or more (two in this embodiment) locking portions 36a provided on the side of the bolt body 29 opposite to the upper surface of the cover body 10; and at least one or more (two in this embodiment) locking portions 36b provided on the side of the cover body 10 opposite to the lower surface of the bolt body 29.

[0113] The locking portion 36a is composed of a wall portion protruding from the upper surface of the plug body 29. The locking portion 36a extends radially along the plug body 29 and is provided in such a way that its upper end is at the same radial height as the inclined upper surface of the plug body 29. In addition, the locking portion 36a is provided symmetrically across the central hole 33a from the plug body 29.

[0114] The locking portion 36b is formed by cutting a part of the lower peripheral wall 10f that protrudes from the lower surface of the cover body 10. One end (left end) of the locking portion 36b in one direction is formed by a vertical surface, and the other end (right end) is formed by an inclined surface. In addition, the locking portion 36b is provided symmetrically across the shaft hole 19a of the cover body 10.

[0115] In the stop mechanism 36, with the bolt 29 (middle bolt 12) closing the lower side of the cover body 10, the locking part (wall part) 36a is locked to the locked part (groove part) 36b, thereby restricting the bolt 29 (middle bolt 12) from rotating about the axis relative to the cover body 10.

[0116] Therefore, it is possible to prevent the bolt 29 (middle bolt 12) from rotating around the axis while loading and unloading by rotating the cover unit 3 relative to the container body 2, and to prevent the engagement of the sliding shaft 30 (middle bolt 12) with the first retaining member 23 (cover 11) from being released.

[0117] On the other hand, in the stop mechanism 36, when the bolt 29 (middle bolt 12) opens the lower part of the cover body 10, the locking part (wall part) 36a is released from the state of being locked by the locking part (groove part) 36b. As a result, the bolt 29 (middle bolt 12) can be easily rotated about an axis relative to the cover body 10.

[0118] Furthermore, in the stop mechanism 36, when the bolt 29 (middle bolt 12) rotates about an axis relative to the cover body 10, the locking part (wall part) 36a slides into contact with the lower end of the lower peripheral wall 10f, and the bolt 29 is separated from the waterproof sealant 20. Therefore, the bolt 29 (middle bolt 12) does not contact the waterproof sealant 20, and the bolt 29 (middle bolt 12) can be easily rotated about an axis relative to the cover body 10.

[0119] Furthermore, in the stop mechanism 36, as long as the aforementioned locking part 36a is locked to the locked part 36b, it is not limited to the case where the locking part 36a is composed of a wall and the locked part 36b is composed of a groove. The structures of these locking parts 36a and locked parts 36b can be appropriately modified.

[0120] In the cover unit 3 of this embodiment, which has the structure described above, the bolt 29 (middle bolt 12) closes the lower part of the cover body 10, thereby closing the flow path R. From this state, while holding the handle 8b with one hand, the operating lever 24a is pressed downward using the thumb or the like.

[0121] At this point, starting from the state where the end of the sliding shaft 30 abuts against the cover component 24, the cover component 24 (cover body 11) rotates (moves) downward against the force of the first helical spring 21, thereby causing the sliding shaft 30 (middle bolt 12) to slide (move) downward. As a result, the bolt 29 (middle bolt 12) opens the lower part of the cover body 10, and the flow path R is opened.

[0122] In addition, when the plug body 29 (middle plug 12) is subjected to pressure inside the container body 2, the sliding shaft 30 (middle plug 12) slides (moves) downward, thereby the head 30b overcomes the force of the second helical spring 31 and opens the lower part of the central hole 33a, allowing air to pass through the vent 18 to the inside of the container body 2.

[0123] In the lid unit 3 of this embodiment, starting from this state, by tilting the container body 2 forward, the beverage contained in the container body 2 can be poured out from the inlet 15 through the open flow path R.

[0124] On the other hand, in the cover unit 3 of this embodiment, by releasing the pressing operation on the operating lever 24a, the cover member 24 (cover body 11) which is stressed by the first helical spring 21 rotates (moves) upward. In addition, the sliding shaft 30 (middle bolt 12) which is stressed by the first helical spring 21 slides (moves) upward. As a result, the bolt 29 (middle bolt 12) closes the lower part of the cover body 10, and the flow path R is closed.

[0125] In addition, by sliding (moving) the sliding shaft 30 (middle bolt 12) upward, the head 30b, which is subjected to force by the second helical spring 31, closes the lower side of the center hole 33a.

[0126] In the cap unit 3 of this embodiment, the aforementioned shoulder sealing member 9B seals the shoulder 2d of the container body 2 with the shoulder member 8. This prevents water or other substances from seeping into the gap between the shoulder 2d and shoulder member 8 of the container body 2 during washing, thereby maintaining hygiene between the shoulder 2d and shoulder member 8 of the container body 2.

[0127] Furthermore, in the cover unit 3 of this embodiment, a flow path forming part 25 that forms part of the flow path R is provided in the cover member 22 (cover body 11). As a result, it is possible to prevent beverage in the flow path R from flowing into the inside of the cover body 11 (specifically, between the cover member 22 and the cover member 24), and to maintain the hygiene of the flow path R.

[0128] Furthermore, in the cover unit 3 of this embodiment, when the aforementioned middle bolt 12 opens the flow path R, the middle bolt 12 can be freely attached to and detached from the cover body 11. Specifically, when the bolt body 29 (middle bolt 12) opens the lower part of the cover body 10, the sliding shaft 30 on the middle bolt 12 side can be freely attached to and detached from the first retaining member 23 on the cover body 11 side by screwing it in.

[0129] Therefore, in the cover unit 3 of this embodiment, with the lower part of the cover body 10 open by the bolt 29 (middle bolt 12), the cover body 11 and the middle bolt 12 can be removed from the cover body 10, and the cover unit 3 can be easily disassembled.

[0130] Therefore, in this cover unit 3, the flow path R can be easily cleaned after the cover body 10, cover body 11, and middle plug 12 have been disassembled. Furthermore, since they can be cleaned separately after being disassembled, the cover body 10, cover body 11, and middle plug 12 can be kept hygienic.

[0131] As described above, the lid unit 3 of this embodiment simplifies the structure and improves cleanability. Therefore, by providing such a lid unit 3, the ease of use can be further improved in the lidded container 1 of this embodiment.

[0132] 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.

[0133] For example, the aforementioned shoulder-filled document 9B is not limited to the above-mentioned... Figure 13 The structures shown in (A) to (C) can also be adopted. Figure 14 The structures shown in (A) to (C) are as follows.

[0134] Specifically, in Figure 14 In the structures shown in (A) to (C), the upper surface of the shoulder filling member 9B is flattened to match the shape of the fitting recess 8a, and two elastic ribs 9a are provided protruding downward from the inner and outer peripheral ends of the lower surface of the shoulder filling member 9B.

[0135] With this structure, it is also possible to prevent water or other substances from seeping into the gap between the shoulder 2d and the shoulder member 8 of the container body 2 during cleaning, thereby keeping the shoulder 2d and the shoulder member 8 of the container body 2 hygienic.

[0136] Furthermore, the aforementioned mouth filling fitting 9A and shoulder filling fitting 9B are constructed separately, but they can also be configured as follows: Figure 15 As shown, this structure is formed by integrally using these filling elements 9A and shoulder filling elements 9B.

[0137] Furthermore, while the above embodiment exemplifies the lidded container 1 used in tabletop kettles, the present invention can also be widely applied to beverage containers in which a gap is formed between the shoulder and shoulder component of the container body.

[0138] Specifically, in the above embodiment, a structure in which the shoulder member 8 is fitted into the neck portion 2c of the container body 2 is adopted. However, as a shoulder member, a structure in which a part of the cap body 10 is fitted into the neck portion 2c of the container body 2 can be used to prevent water or other substances from seeping into the gap between the shoulder portion 2d of the container body 2 and the cap body 10 during cleaning.

[0139] Furthermore, in the above embodiments, a covered container 1 with heat preservation and cold preservation functions is exemplified by the container body 2 with the vacuum insulation structure described above. However, the present invention can also be applied to covered containers (beverage containers) with a container body that does not have a vacuum insulation structure.
