Description

Technical Field

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

[0002] Conventionally, there exists a cap unit that is detachably mounted to the neck of a container body with an upper opening (see, for example, Patent Documents 1 and 2). A cap body for opening and closing a liquid inlet is rotatably mounted on the upper part of the cap unit via a hinge. A force-applying member provided at the hinge applies force to the cap body in the opening direction. The cap unit is provided with a cap locking mechanism that fixes the cap body in the position where the liquid inlet is closed. In the cap locking mechanism, pressing an operation button releases the cap body from its locked state, allowing the cap body to rotate in the opening direction due to the force applied by the force-applying member.

Detailed Implementation

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

[0045] As one embodiment of the present invention, for example, for having Figures 1-5 The lidded container 100 of the lid unit 1 shown will be described.

[0046] also, Figure 1 This is a cross-sectional view showing the structure of a covered container 100 having a cover unit 1. Figure 2 This is a three-dimensional view showing the closed state of cover unit 1. Figure 3 This is a cross-sectional view showing the closed state of cover unit 1. Figure 4 This is a cross-sectional view showing the unlocked state of cover unit 1. Figure 5 This is a perspective view showing the open state of cover unit 1.

[0047] like Figure 1 As shown, the lidded container 100 of this embodiment includes a lid unit 1, a container body 2 on which the lid unit 1 is detachably mounted, and a cup 3 which is detachably mounted relative to the container body 2 in a state of covering the lid unit 1.

[0048] The lidded container 100 is a beverage container that can keep the beverage (liquid) contained in the container body 2 warm or cold through the container body 2 having a vacuum insulation structure.

[0049] Specifically, the container body 2 is a double-layered container, comprising a bottomed cylindrical outer container 4 made of, for example, stainless steel, and an inner container 5, 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 portion 2a, a generally cylindrical cylindrical body portion 2b that rises from the outer periphery of the bottom portion 2a, and a generally cylindrical neck portion 2c that narrows at the upper side of the cylindrical body portion 2b. In addition, the upper end of the neck portion 2c has a circular opening as the upper opening portion 2d of the container body 2.

[0051] The inner circumferential surface of the neck portion 2c is narrower than the inner circumferential surface of the cylindrical portion 2b. Furthermore, a first external thread portion 7 is provided on the outer circumferential surface of the neck portion 2c. On the other hand, a first internal thread portion 8 is provided on the inner circumferential surface of the neck portion 2c. Additionally, an annular protrusion 9 is provided below the first internal thread portion 8, protruding along the entire circumference in the direction of the narrowing diameter.

[0052] The cup 3 is made of, for example, a heat-resistant resin such as polypropylene, and has a generally circular bottom wall 3a and a portion extending upwards from the periphery of the bottom wall 3a (in...). Figure 1 and Figure 3 The cylindrical peripheral wall 3b, which stands upright (at the bottom), is formed as a bottomed cylindrical shape.

[0053] With the bottom wall portion 3a facing upwards, the cup 3 is easily attached and detached from the outside of the neck portion 2c of the container body 2 by screwing it on. Therefore, a second internal thread portion 10 that engages with the first external thread portion 7 is provided on the inner circumferential surface of the peripheral wall portion 3b.

[0054] In addition, a handle 3c is provided on the side of the cup 3 for the user to hold. The handle 3c has a ring shape at its upper and lower ends that connects to the outer peripheral surface of the peripheral wall 3b.

[0055] In this embodiment, the cover unit 1 constitutes a plug that closes the upper opening 2d of the container body 2. Specifically, as... Figures 1-5 As shown, the cover unit 1 includes: a cover body 13 that closes the upper opening 2d of the container body 2 and is provided with a liquid inlet 11 and a vent 12 communicating with the inside of the container body 2; a cover body 15 that, when rotatably mounted on the cover body 13 via a first hinge 14, opens and closes the liquid inlet 11 and the vent 12; and a cover locking mechanism 16 that fixes the cover body 15 relative to the cover body 13 when the cover body 15 closes the liquid inlet 11 and the vent 12.

[0056] Furthermore, in the lidded container 100 of this embodiment, the side of the lid unit 1 where the first hinge portion 14 is provided is designated as the "rear side", and the side opposite to the side where the first hinge portion 14 is provided is designated as the "front side".

[0057] The cap body 13 is made of synthetic resin such as polypropylene. The cap body 13 has a peripheral wall portion 13a formed in a generally cylindrical shape, an upper wall portion 13b covering the upper surface of the peripheral wall portion 13a, an opening forming recess 13c formed by recessing the inner side of the upper wall portion 13b, and an injection port portion 13d protruding obliquely upward from the front side of the opening forming recess 13c.

[0058] The cap body 13 is installed relative to the container body 2 by screwing it in, with the cap inserted into the inside of the neck portion 2c from the upper opening 2d of the container body 2. Therefore, a second external thread portion 17 that engages with the first internal thread portion 8 is provided on the outer peripheral surface of the peripheral wall portion 13a.

[0059] The liquid inlet 11 is located on the front side of the bottom of the inlet forming recess 13c, and is positioned lower than the vent 12, so that it is a large, circular opening when viewed from above. The vent 12 is located on the rear side of the inlet forming recess 13c, and is positioned higher than the liquid inlet 11, so that it is a smaller, circular opening when viewed from above.

[0060] A waterproof sealant 18 is detachably installed on the outer periphery of the lower end side of the cover body 13. The waterproof sealant 18 is an annular sealing component used to seal the protrusion 9 (container body 2) and the peripheral wall 13a (cover body 13), and is made of, for example, heat-resistant rubber such as silicone rubber, or elastic components such as elastomers.

[0061] The cover body 13 is provided with a lower flange 13e that protrudes circumferentially from the lower end of the peripheral wall portion 13a in the expanding direction. On the other hand, the waterproof sealant 18 is provided with a groove 18a formed by cutting the inner circumferential surface circumferentially. Thus, the waterproof sealant 18 is fitted into the outer periphery of the lower end side of the cover body 13 with the lower flange 13e fitted into the groove 18a.

[0062] The waterproof sealant 18 can be removed from the outer periphery of the lower end side of the cap body 13 by elastically deforming (stretching). This allows the cap body 13 and the waterproof sealant 18 to be cleaned separately, thus maintaining hygiene between them.

[0063] Furthermore, at least one or more (one in this embodiment) elastic flange portions 18b are provided protruding throughout the entire circumference of the outer periphery of the waterproof sealant 18 in the expansion direction. When the cap body 13 is installed on the container body 2, the waterproof sealant 18 causes the elastic flange portion 18b to elastically deform and simultaneously become in close contact with the protrusion 9 throughout its entire circumference. Thus, the waterproof sealant 18 can be used to seal (waterproof) the protrusion 9 (container body 2) and the peripheral wall portion 13a (cap body 13).

[0064] The cover 15 is made of, for example, a synthetic resin such as polypropylene. The cover 15 has a top wall portion 15a that is formed in a generally circular shape and a peripheral wall portion 15b that descends in a generally cylindrical shape from the periphery of the top wall portion 15a.

[0065] The cover 15 is rotatably mounted via a first hinge 14 located on the upper part of the rear end of the cover body 13. Furthermore, the cover 15 is positioned such that a first force-applying member 19, located inside the first hinge 14, applies force in the direction of opening the liquid inlet 11 and the vent 12 (opening direction). The first force-applying member 19 can be a spring such as a torsion coil spring, or an elastic member such as rubber or an elastomer.

[0066] Furthermore, a first blocking portion 15c that closes the liquid inlet 11 and a second blocking portion 15d that closes the vent 12 are provided on the lower inner surface of the cover 15. The first blocking portion 15c is provided in a generally cylindrical shape protruding from the lower surface of the top wall portion 15a toward the liquid inlet 11. The second blocking portion 15d is provided in a generally columnar shape protruding from the lower surface of the top wall portion 15a toward the vent 12.

[0067] A sealing member 20 is detachably installed on the lower inner surface of the cover 15. The sealing member 20 is a sealing component used to seal the liquid inlet 11 and the vent 12, and is made of elastic components such as heat-resistant rubber or elastomers.

[0068] The sealing member 20 is provided with a first plug portion 20a and a second plug portion 20b. The first plug portion 20a is provided in a generally dome-shaped manner, protruding downward from a position opposite to the first blocking portion 15c. The second plug portion 20b is provided in a generally dome-shaped manner, protruding downward from a position opposite to the second blocking portion 15d.

[0069] The sealing member 20 is fitted into the lower inner surface of the cover body 15 with the first sealing part 15c fitted inside the first plug part 20a and the second sealing part 15d fitted inside the second plug part 20b.

[0070] The sealing element 20 is positioned above the cap body 13, where the cap body 15 closes the cap main body 13. The first plug portion 20a elastically deforms and simultaneously seals against the area around the liquid inlet 11, while the second plug portion 20b elastically deforms and simultaneously seals against the area around the vent 12. Thus, the sealing element 20 can seal (block) both the liquid inlet 11 and the vent 12.

[0071] On the other hand, the sealing cap 20 can be removed from the cap 15. Thus, the cap 15 and the sealing cap 20 can be cleaned separately, thereby maintaining hygiene between the cap 15 and the sealing cap 20.

[0072] The cover locking mechanism 16 includes: a second hinge portion 21 located on the side (front side) opposite to the first hinge portion 14 of the cover body 15; a rotating member 22 rotatably mounted via the second hinge portion 21; and a second force-applying member 23 applying force to the rotating member 22 in one direction of rotation.

[0073] The rotating component 22 is rotatably mounted via a second hinge portion 21 located at the corner of the front side of the top wall portion 15a and the peripheral wall portion 15b of the cover 15. The rotating component 22 has: a locking portion 22a located on the side of the cover 15 across the front side of the second hinge portion 21; and an operating portion 22b located on the upper surface of the cover 15 across the second hinge portion 21.

[0074] The locking portion 22a has an arm shape that extends downward from the second hinge portion 21 and is disposed inside the front recess 24a, which is formed by recessing the peripheral wall portion 15b in accordance with the locking portion 22a.

[0075] The operating part 22b has a button shape that extends rearward from the second hinge part 21 and is generally circularly enlarged in the in-plane direction, and is disposed inside the upper recess 24b formed by recessing the top wall part 15a in correspondence with the operating part 22b.

[0076] The second force-applying component 23, for example, is a coil spring, disposed in a compressed state between the bottom surface of the upper recess 24b and the lower surface of the operating part 22b. Furthermore, the second force-applying component 23 is positioned closer to the second hinge portion 21 (front side) than the center of the operating part 22b. Thus, the second force-applying component 23 applies an upward force to the operating part 22b.

[0077] On the other hand, the operating part 22b is configured such that, when force is applied by the second force-applying member 23, at least a portion protrudes from the upper recess 24b above the upper surface of the top wall portion 15a. Specifically, the rear end of the operating part 22b is configured to protrude from the upper recess 24b above the upper surface of the top wall portion 15a.

[0078] The cap locking mechanism 16 has a locking portion 25 provided on the rotating member 22 side and a locked portion 26 provided on the cap body 13 side. The locking portion 25 is composed of a hook portion protruding rearward from the front end of the locking portion 22a. The locked portion 26 is composed of a hook portion protruding forward from the upper front side of the injection port 13d.

[0079] In the cover locking mechanism 16, such as Figure 2 and Figure 3As shown, at the position where the cover 15 closes the upper part of the cover body 13, the locking part 25 on the side of the rotating member 22, which is subjected to force by the second force-applying member 23, is locked to the locking part 26 on the side of the cover body 13, thereby overcoming the force of the first force-applying member 19 and fixing the cover 15 relative to the cover body 13.

[0080] The rotating component 22 can rotate freely between the locked position where the locking part 25 is locked to the locked part 26 and the unlocked position where the locking state between the locking part 25 and the locked part 26 is released.

[0081] Therefore, in the cover locking mechanism 16, as Figure 4 As shown, pressing the operating part 22b of the rotating member 22 downwards overcomes the force of the second force-applying member 23, thereby allowing the rotating member 22 to rotate from the locked position to the unlocked position, simultaneously releasing the locking state between the locking part 25 and the locked part 26. Thus, as... Figure 5 As shown, the cover 15, which is subjected to force by the first force-applying member 19, can rotate in the opening direction. Furthermore, in the rotating member 22, the length from the end of the second hinge portion 21 to the end of the operating portion 22b is longer than the length from the end of the second hinge portion 21 to the end of the locking portion 22a.

[0082] On the other hand, in the cover locking mechanism 16, from Figure 5 Starting from the open state, the cover 15 rotates towards the upper part of the closed cover body 13 (closing direction) against the force of the first force-applying member 19. This causes the locking part 25 to slide into contact with the locked part 26, and simultaneously, against the force of the second force-applying member 23, the rotating member 22 rotates from the locked position to the unlocked position. Furthermore, the locking part 25 passes over the locked part 26, thereby using the force of the second force-applying member 23 to rotate the rotating member 22 from the unlocked position to the locked position. At this point, the locking part 25 is locked to the locked part 26.

[0083] Therefore, as Figure 2 and Figure 3 As shown, with the cover 15 closing the upper part of the cover body 13, the cover 15 can be fixed relative to the cover body 13 by overcoming the force of the second force-applying component 23.

[0084] In a lidded container 100 equipped with a lid unit 1 having the aforementioned structure, after the cup 3 is removed from the container body 2, the operating part 22b of the rotating member 22 is pressed. This causes the lid 15, which is subjected to force by the first force-applying member 19, to rotate in the opening direction, opening the liquid inlet 11 and the vent 12. From this state, the container body 2 is tilted forward, allowing the beverage inside the container body 2 to be poured into the cup 3 through the liquid inlet 11 from the inlet 13d.

[0085] Furthermore, when the beverage inside the container body 2 is poured out through the liquid inlet 11 from the injection port 13d, external air is introduced into the interior of the container body 2 through the vent 12. This prevents air from flowing in through the liquid inlet 11 while allowing the beverage inside the container body 2 to be poured out smoothly through the liquid inlet 11 from the injection port 13d.

[0086] As described above, in the cover unit 1 of this embodiment, the operability of releasing the cover locking mechanism 16 from the locked state of the cover 15 can be improved. That is, since the operation part 22b has a button shape that expands in the in-plane direction, it is particularly easy to press the operation part 22b so that even a young child can easily release the locked state.

[0087] Furthermore, in the cover unit 1 of this embodiment, since the rear end of the operation part 22b is configured to protrude from the upper recess 24b above the upper surface of the top wall part 15a, the pressing position of the operation part 22b can be intuitively identified.

[0088] In addition, in the cover unit 1 of this embodiment, a second force-applying member 23 is provided at a position closer to the second hinge portion 21 (front side) than the center portion of the operation portion 22b, thereby reducing the pressure increase during the pressing operation of the operation portion 22b.

[0089] Similarly, in the rotating member 22, the length from the end of the second hinge portion 21 to the end of the operating portion 22b is longer than the length from the end of the second hinge portion 21 to the end of the locking portion 22a, thereby reducing the pressing force during the pressing operation of the operating portion 22b.

[0090] In addition, in the cover unit 1 of this embodiment, the operating part 22b, which extends to the rearward side with the second hinge part 21 on the front side as a fulcrum, is designed to rotate obliquely downward. As a result, compared with simple up and down movement, it is easier to apply force obliquely downward when pressing the operating part 22b, and the cover 15 can be opened even if the pressing is slowly released after the pressing operation.

[0091] Furthermore, in the cover unit 1 of this embodiment, the cover locking mechanism 16 has fewer components, allowing for the use of inexpensive components to simplify its construction. Additionally, the second force-applying member 23 is positioned closer to the second hinge portion 21 (front side) than the center of the operating portion 22b, enabling the use of a smaller helical spring as the second force-applying member 23.

[0092] Furthermore, in the lidded container 100 of this embodiment, the lid unit 1 is covered by the cup 3 installed on the container body 2, thereby preventing erroneous operation of the operation unit 22b.

[0093] Here, with the lid unit 1 and cup 3 installed on the container body 2, the front side of the locking part 22a abuts against the inner surface of the peripheral wall 3b of the cup 3 before the locking state of the locking part 25 and the locked part 26 is released. That is, the rotation of the rotating member 22 from the locked position to the locked-out position is prevented by the cup 3. Therefore, even if the rotating member 22 attempts to rotate towards the locked-out position due to an impact such as falling, the locking state of the locking part 25 and the locked part 26 will not be released. As a result, it is possible to prevent the beverage inside the container body 2 from leaking to the outside.

[0094] As described above, in the lid unit 1 of this embodiment, the structure of the lid locking mechanism 16 can be simplified, and the operability of releasing the lid locking mechanism 16 from the locked state of the lid body 15 can be improved. Therefore, in the lid container 100 of this embodiment, by providing such a lid unit 1, the ease of use can be further improved.

[0095] 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.

[0096] For example, in the aforementioned lidded container 100, the container body 2 generally has a cylindrical shape, but 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, printed, etc.

[0097] Furthermore, the above embodiments illustrate the application of the present invention to a covered container 100 that maintains heat preservation or cold preservation functions through the container body 2 with the aforementioned vacuum insulation structure, but it is not limited to covered containers having such a container body 2 with a vacuum insulation structure. That is, the present invention can be widely applied to covered containers in which the lid unit is detachably mounted relative to the container body.
