Description

Technical Field

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

[0002] Previously, there were containers with lids (for example, see Patent Document 1 below) that had a lid unit (plug) that could be detachably installed on the neck of the container body with an upper opening to close the upper opening of the container body.

[0003] For example, Patent Document 1 discloses a covered beverage container, which has a cover plate and an open / closed lid. The cover plate closes the upper opening of the container body and has a liquid passage hole formed near the front peripheral wall. The open / closed lid blocks the liquid passage hole provided on the upper surface of the cover plate, which can be rotated in the front-back direction by means of a left-right rotating shaft.

[0004] Patent Document 1: Japanese Patent Application Publication No. 2008-260544

[0005] However, in the beverage container with a lid described in the aforementioned Patent Document 1, the lid can be kept closed except when drinking the beverage in the container, thus providing a high heat preservation effect. On the other hand, the lid needs to be opened and closed each time you drink, which can sometimes be annoying. Summary of the Invention

[0006] The present invention was made in view of this prior art, and its object is to provide a lid unit that allows for easy opening and closing of the lid, and a lidded container that further improves ease of use by having such a lid unit.

[0007] To achieve the above objectives, the present invention provides the following apparatus.

[0008] [1] A cover unit, which is detachably and removably installed on a container body with an upper opening, characterized in that it comprises:

[0009] The lid body seals the upper opening of the container body and is provided with a liquid inlet;

[0010] The cover, while rotatably mounted on the cover body, allows for the opening and closing of the liquid inlet; and

[0011] The cover opening and closing mechanism performs the opening and closing operation of the cover between the closed position where the cover closes the liquid inlet and the open position where the cover opens the liquid inlet.

[0012] The aforementioned cover opening and closing mechanism has a sliding rod that is slidably mounted on the cover body.

[0013] The cover is rotated between the closed position and the open position by means of the magnetic attraction between the cover and the slide rod, in conjunction with the sliding operation of the slide rod.

[0014] [2] According to the cover unit described in [1] above, the cover body is characterized in that, in the state where the bearing recess provided on any one of the surfaces of the cover body and the cover body facing each other is engaged with the bearing protrusion provided on any other surface of the surfaces of the cover body and the cover body facing each other, the cover body is rotatably installed relative to the cover body.

[0015] [3] The cover unit according to [1] or [2] above is characterized in that the cover body can be freely installed and detached from the cover body by means of a magnetic attraction between a magnet provided in either the cover body or the slide rod and a magnet or magnetic body provided in the other of the cover body or the slide rod.

[0016] [4] According to the cover unit described in [3] above, the cover body has a stop that prevents the cover from falling off at the closed position.

[0017] [5] According to the cover unit described in [1] or [2] above, the cover opening and closing mechanism is characterized in that it has a force-applying component that applies force to the slide rod on one side toward the sliding direction.

[0018] By overcoming the force applied by the force-applying component and sliding the slide bar to the other side of the sliding direction from the state where the liquid inlet is closed by the cover, the cover rotates from the closed position to the open position.

[0019] [6] According to the lid unit described in [5] above, the lid opening and closing mechanism has an operating lever, which slides the slide rod while holding the handle portion provided on the side surface of the container body.

[0020] The aforementioned operating lever is configured to pass through the hole provided in the aforementioned handle portion and extend from the aforementioned slide bar toward the side surface of the aforementioned container body and between the aforementioned handle portion.

[0021] [7] A lidded container, comprising:

[0022] The cover unit as described in any one of claims [1] to [6]; and

[0023] The container body is for mounting the aforementioned cover unit.

[0024] [8] The lidded container according to [7] above is characterized in that the container body has a vacuum insulation structure.

[0025] As described above, according to the present invention, it is possible to provide a lid unit that allows for easy opening and closing of the lid, and a lidded container that further improves ease of use by having such a lid unit. Attached Figure Description

Detailed Implementation

[0039] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0040] As one embodiment of the present invention, for example... Figures 1 to 11 The lidded container 100 with lid unit 1 shown will be described.

Figure 11 This is a perspective top view showing the lid 11 in the open position within the covered container 100.

[0043] like Figure 1 as well as Figure 2 As shown, the lidded container 100 of this embodiment includes a lid unit 1 of this embodiment and a container body 2 on which the lid unit 1 is detachably mounted.

[0044] The lidded container 100 is a mug (beverage container) that can keep the beverage (contents) contained in the container body 2 hot or cold by utilizing the container body 2 which has a vacuum insulation structure.

[0045] Specifically, such as Figures 3-6 As shown, the container body 2 is, for example, a container with a bottomed cylindrical outer container 3 made of stainless steel or the like and an inner container 4, and the openings of the two are joined together in a state where the inner container 4 is housed inside the outer container 3.

[0046] In addition, 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, in a chamber that has been depressurized (evacuated) to a high vacuum by blocking the exhaust hole located at the center of the bottom surface of the outer container 3.

[0047] The container body 2 has a generally circular bottom 2a and a generally cylindrical body 2b that rises from the outer periphery of the bottom 2a. In addition, the upper end of the body 2b has a circular opening as the upper opening 2c of the container body 2.

[0048] In addition, the container body 2 has a bottom part 6 installed at the bottom 2a and a shoulder part 7 installed at the upper end of the body 2b.

[0049] The bottom component 6 and the shoulder component 7 are made of heat-resistant resins such as polypropylene (PP). Alternatively, thermoplastic resins such as acrylonitrile butadiene styrene (ABS) or resins with excellent wear resistance such as polyoxymethylene (POM) can also be used.

[0050] The bottom component 6 is formed as a bottomed cylinder. The bottom component 6 is bonded to the step portion 2d between the bottom 2a and the body 2b of the container body 2 using adhesive, thereby installing the bottom component 6 to cover the bottom 2a of the container body 2.

[0051] The shoulder component 7 is generally cylindrical. The shoulder component 7 is bonded with adhesive in a state where it fits into the step portion 2e between the torso 2b and the upper opening 2c of the container body 2, thereby installing the shoulder component 7 in a state where it covers the area around the upper opening 2c (the upper end of the torso 2b) of the container body 2.

[0052] Additionally, a handle 8 is provided on the side surface of the container body 2. The handle 8 has a gripping part 8a, which is a part for the user to hold, and extends vertically by connecting a lower arm 6a extending from the side surface of the bottom member 6 and an upper arm 7a extending from the side surface of the shoulder member 7. The two ends of the gripping part 8a are fixed to the lower arm 6a and the upper arm 7a by threads.

[0053] Furthermore, the container body 2 has a generally cylindrical shape, but the shape of the container body 2 is not particularly limited and can be appropriately modified in accordance with dimensions, appearance design, etc. In addition, painting or printing can be applied to the outer peripheral surface of the container body 2.

[0054] Furthermore, the handle 8 is not necessarily limited to the shape described above; for example, it may be a component that protrudes from the side surface of the shoulder component 7 and extends downward.

[0055] Furthermore, in this embodiment, the side where the handle 8 is provided will be referred to as the "rear side" of the covered container 100, and the opposite side will be referred to as the "front side" of the covered container 100.

[0056] In this embodiment, the cover unit 1 constitutes a plug that closes the upper opening 2c of the container body 2.

[0057] Specifically, such as Figures 3-9 As shown, the cover unit 1 includes: a cover body 10, which closes the upper opening 2c of the container body 2 and is provided with a liquid inlet 9; a cover body 11, which is rotatably mounted on the cover body 10 to open and close the liquid inlet 9; and a cover opening and closing mechanism 12, which performs opening and closing operations on the cover body 11 between a closed position where the cover body 11 closes the liquid inlet 9 and an open position where the cover body 11 opens the liquid inlet 9.

[0058] The cover body 10 is made of a heat-resistant resin such as polypropylene (PP) or polymethylpentene (PMP). The cover body 10 has: a generally cylindrical peripheral wall portion 10a; a generally circular plate-shaped upper wall portion 10b covering the upper part of the peripheral wall portion 10a; an upper edge portion 10c that gradually expands in diameter from the periphery of the upper wall portion 10b and protrudes upward; and a flange portion 10d that protrudes from the end of the upper edge portion 10c in the direction of expansion.

[0059] A pair of symmetrical liquid inlets 9 are provided on the left and right sides of the upper wall portion 10b, separated by the central portion. Each liquid inlet 9 opens in a fan shape in the rotation direction of the cover body 11 and within a specified angular range (approximately 80° in this embodiment).

[0060] In addition, a top plate 13 is installed on the upper part of the cover body 10. The top plate 13 is made of the same material as the cover body 10 and is installed integrally with the flange portion 10d by fusion bonding in a state covering the upper part of the cover body 10.

[0061] A pair of drinking ports 13a are provided on the left and right sides of the top plate 13, separated by the central part. The pair of drinking ports 13a are fan-shaped openings in a shape corresponding to the liquid inlet 9 at the positions opposite to the liquid inlet 9.

[0062] The lid body 10 is configured such that, with the peripheral wall portion 10a inserted into the inner side of the container body 2 from the upper opening portion 2c, the flange portion 10d abuts against the upper end of the container body 2, thereby closing the upper opening portion 2c of the container body 2.

[0063] In addition, a waterproof sealant 14 is detachably installed on the peripheral wall 10a of the cap body 10. The waterproof sealant 14 is an annular sealing component used to seal the cap body 10 and the container body 2. The waterproof sealant 14 is made of, for example, heat-resistant rubber such as silicone rubber or elastic components such as elastomers.

[0064] Correspondingly, annular fitting recesses 10e are provided on the outer periphery of the peripheral wall portion 10a, covering the entire circumference. The waterproof sealant 14 is fitted into the fitting recesses 10e. On the other hand, the waterproof sealant 14 can be removed from the fitting recesses 10e (cover body 10) by elastically deforming (stretching) itself.

[0065] Therefore, the waterproof seal 14 and the cover body 10 can be cleaned separately, thereby maintaining hygiene between the waterproof seal 14 and the fitting recess 10e (cover body 10).

[0066] Furthermore, an elastic flange portion 14a protruding throughout the entire circumference in the expansion direction is provided on the outer peripheral surface of the waterproof seal 14. When the peripheral wall portion 10a is embedded inside the container body 2, the waterproof seal 14 is in a state where the elastic flange portion 14a elastically deforms while being tightly attached to the inner peripheral surface of the inner container 4 (container body 2) throughout the entire circumference. As a result, a liquid-tight seal (waterproofing) can be achieved between the cap body 10 and the container body 2.

[0067] The cover 11 is made of a heat-resistant resin such as polypropylene (PP) or polymethylpentene (PMP). The cover 11 has: a central plate 11a located in the center of the cover 11; a pair of gates 11b located on the left and right sides separated by the central plate 11a; and a pair of notches 11c located between the pair of gates 11b.

[0068] The central plate 11a is formed in a circular shape corresponding to the central portion of the upper wall portion 10b. On the other hand, each gate 11b is formed in a fan shape corresponding to each liquid inlet 9. Furthermore, each notch 11c is cut between a pair of gates 11b to form a fan shape.

[0069] The cover 11 is located inside the peripheral wall portion 10a of the cover body 10, the central plate 11a is opposite to the central portion of the lower surface of the upper wall portion 10b, and the cover 11 is installed in a manner that allows it to rotate freely between a closed position where a pair of gates 11b closes a pair of liquid inlets 9 and an open position where a pair of gates 11b open a pair of liquid inlets 9.

[0070] Specifically, in the surfaces of the cover body 10 and the cover 11 facing each other, a bearing protrusion 15a is provided on the lower surface of the cover body 10. On the other hand, a bearing recess 15b is provided on the upper surface of the cover 11.

[0071] The bearing protrusion 15a is, for example, made of a metal pin and is mounted in a state that passes through the center of the upper wall portion 10b and protrudes in the vertical direction. The bearing recess 15b is, for example, made of a shaft hole that recesses the center of the upper surface of the central plate 11a and is provided to protrude from the center of the lower surface of the central plate 11a in a bottomed cylindrical shape in order to form the shaft hole.

[0072] Therefore, in the cover unit 1 of this embodiment, with the shaft pin (bearing protrusion 15a) inserted in the shaft hole (bearing recess 15b), the cover body 11 is installed in a manner that allows it to rotate freely around the central axis of the cover body 10.

[0073] Furthermore, in the cover unit 1 of this embodiment, it is not necessarily limited to a structure in which a shaft pin (bearing protrusion 15a) is inserted into the shaft hole (bearing recess 15b). It is acceptable as long as the bearing protrusion 15a and the bearing recess 15b engage with each other so that the cover body 11 can be rotatably installed relative to the cover body 10.

[0074] In addition, in the cover unit 1 of this embodiment, in contrast to the structure in which a bearing protrusion 15a is provided on the cover body 10 side and a bearing recess 15b is provided on the cover body 11 side, it can also be formed with a bearing recess 15b provided on the cover body 10 side and a bearing protrusion 15a provided on the cover body 11 side.

[0075] The lid opening and closing mechanism 12 includes: a slide rod 16 which is slidably mounted on the lid body 10; a force-applying member 17 which applies force to the slide rod 16 on the side facing the sliding direction; and an operating lever 18 which slides the slide rod 16 while holding the handle portion 8 of the container body 2.

[0076] The slide bar 16 is made of a heat-resistant resin such as polypropylene (PP) or polymethylpentene (PMP) and has a flat plate shape extending in the front-back direction. The slide bar 16 is disposed between the upper wall portion 10b of the cover body 10 and the top plate 13 and is installed in a manner that allows it to slide in the front-back direction.

[0077] Specifically, on the surfaces of the cover body 10 and the slide rod 16 facing each other, a first guide protrusion 19a and a second guide protrusion 19b are provided on the upper surface of the cover body 10. On the other hand, a first guide recess 19c and a second guide recess 19d are provided on the lower surface of the slide rod 16.

[0078] The first guide protrusion 19a is located, for example, on the rear side of the upper wall portion 10b, separated from the central portion, and is formed by a protrusion that protrudes upward. The second guide protrusion 19b is, for example, formed by a pivot pin that protrudes upward from the central portion of the upper wall portion 10b. In addition, a through hole 10f is provided on the side surface of the peripheral wall portion 10a of the cover body 10, separated from the central portion, for the slide rod 16 to pass through.

[0079] The first guide recess 19c is, for example, formed by an elongated hole cut along the front-back direction at a position opposite to the protrusion (first guide protrusion 19a) with a width corresponding to the protrusion. The second guide recess 19d is, for example, formed by an elongated hole cut along the front-back direction at a position opposite to the shaft pin (second guide protrusion 19b) with a width corresponding to the shaft pin.

[0080] Therefore, in the cover unit 1 of this embodiment, with the slide rod 16 passing through the through hole 10f, the protrusion (first guide protrusion 19a) is located inside one elongated hole (first guide recess 19c), and the pin (second guide protrusion 19b) is located in another elongated hole (second guide recess 19d), thereby allowing the slide rod 16 to be slidably installed along the front-rear direction of the cover body 10.

[0081] Furthermore, in the cover unit 1 of this embodiment, it is not necessarily limited to a structure in which the protrusions and the pivot pins (first and second guide protrusions 19a, 19b) are located inside the elongated holes (first and second guide recesses 19c, 19d). It is acceptable as long as the first and second guide protrusions 19a, 19b and the first and second guide recesses 19c, 19d engage with each other so that the slide rod 16 can be slidably mounted relative to the cover body 10.

[0082] In addition, in the cover unit 1 of this embodiment, in contrast to the structure in which the first and second guide protrusions 19a and 19b are provided on the cover body 10 side and the first and second guide recesses 19c and 19d are provided on the slide rod 16 side, it can also be formed with the first and second guide recesses 19c and 19d provided on the cover body 10 side and the first and second guide protrusions 19a and 19b provided on the slide rod 16 side.

[0083] In the lid opening and closing mechanism 12, the lid 11 is configured to rotate between a closed position and an open position by means of a magnetic attraction that acts between the lid 11 and the slide bar 16, in conjunction with the sliding operation of the slide bar 16.

[0084] Specifically, the cover opening and closing mechanism 12 has a first magnet 20 disposed on the cover body 11 and a second magnet 21 disposed on the slide bar 16.

[0085] The first magnet 20 is located near the boundary between a gate 11b and a notch 11c around the bearing recess 15b of the central plate 11a, and is configured to be embedded in the resin forming the cover 11.

[0086] The second magnet 21 is located on one side of the slide bar 16 across the second guide recess 19d, and is configured to be embedded in the resin forming the slide bar 16.

[0087] In the lid opening and closing mechanism 12, the first magnet 20 and the second magnet 21 are magnetically attracted to each other in a mutually opposing state. As a result, the lid 11, located inside the peripheral wall portion 10a of the lid body 10, is kept in a state where it is opposed to the upper wall portion 10b.

[0088] That is, in the cover unit 1 of this embodiment, the cover body 10 can be freely installed and removed from the cover body 11 by utilizing the magnetic attraction force that acts between the first magnet 20 and the second magnet 21.

[0089] Furthermore, in the cover unit 1 of this embodiment, it is formed as described above, with a first magnet 20 provided on the cover body 11 side and a second magnet 21 provided on the slide rod 16 side. However, it can also be formed as if a magnet is provided on either the cover body 11 or the slide rod 16, and a magnetic body that attracts the magnet is provided on the other.

[0090] Additionally, a sliding contact protrusion 22 is provided on the surface of the cover 11 opposite to the upper wall portion 10b, which slides in contact with the lower surface of the upper wall portion 10b. The sliding contact protrusion 22 can reduce the sliding contact resistance between the cover 11 and the lower surface of the upper wall portion 10b when the cover 11 rotates. For example, it is configured to protrude linearly at a small height along the periphery of the central plate 11a and the periphery of the pair of gate plates 11b.

[0091] In the cover unit 1 of this embodiment, as Figure 10 As shown, when the slide bar 16 is located on one side (front side) of the sliding direction, the cover 11 is in a closed position, thus forming a state in which a pair of gates 11b close a pair of liquid inlets 9.

[0092] On the other hand, in the cover unit 1 of this embodiment, such as Figure 11 As shown, when the slide bar 16 is located on the other side (rear side) of the sliding direction, the cover 11 is in the open position, thus becoming a state in which a pair of gates 11b open a pair of liquid inlets 9.

[0093] In the lid opening and closing mechanism 12, the first magnet 20 and the second magnet 21 are magnetically attracted to each other in a mutually opposing state. In coordination with the movement of the second magnet 21 on the slide bar 16 side, the first magnet 20 on the lid body 11 side moves. As a result, the lid body 11 can be rotated between the closed position and the open position in conjunction with the sliding operation of the slide bar 16 in the front-back direction.

[0094] In addition, the cover body 10 is provided with a pair of anti-rotation blocks 23 to prevent the cover body 11 from rotating in the closed position, and a pair of detachment blocks 24 to prevent the cover body 11 from falling off in the closed position.

[0095] When the cover 11 is in the closed position, the anti-rotation block 23 is configured to protrude from between the peripheral wall portion 10a and the upper wall portion 10b in such a way that it abuts against one end of the pair of gates 11b in the direction of rotation.

[0096] The detachment stop 24 is configured to protrude from the inner peripheral surface of the peripheral wall portion 10a along the pair of liquid inlets 9. Therefore, when the cover 11 is in the closed position, even if an external force is applied to the cover 11 in the direction of removal (downward), the cover 11 can be prevented from detaching by the outer peripheral ends of the pair of gates 11b abutting against the detachment stop 24. Thus, the cover 11 can only be installed or removed from the cover body 10 when it is in the open position.

[0097] The force-applying component 17 is, for example, a coil spring, one end (front side) of which is engaged with a first engaging portion 25a provided on the front side of the upper wall portion 10b across the central portion, and the other end (rear side) of which is engaged with a second engaging portion 25b provided on the end side of the slide rod 16.

[0098] Therefore, the force-applying component 17 applies force to the slide rod 16 on one side (front side) in the sliding direction. Thus, in the cover opening and closing mechanism 12, in this state, the cover 11 is in the closed position, and a pair of gates 11b close a pair of liquid inlets 9.

[0099] The operating lever 18 is integrally formed with the slide bar 16 and extends downward from the lower end of the rear side of the slide bar 16. Thus, the operating lever 18 passes through the hole 7b provided in the upper arm 7a and extends towards the side surface of the container body 2 and the handle 8a.

[0100] Therefore, in the lid opening and closing mechanism 12, when the holding part 8a (handle part 8) of the container body 2 is held, by pulling the operating lever 18 with a finger (so-called trigger operation), the force applied by the force-applying member 17 can be overcome, and the slide bar 16 can be slid in the opposite direction (rear side) of the sliding direction. As a result, the lid body 11 can be rotated from the closed position to the open position, thereby opening a pair of liquid inlets 9 by a pair of gates 11b.

[0101] In the lidded container 100 of this embodiment, the beverage (contents) flowing out of the container body 2 through the liquid inlet 9 can be drunk through the drinking port 13a while the container body 2 is tilted in this state.

[0102] On the other hand, after the beverage is consumed, the triggering operation of the operating lever 18 is released. As a result, the slide bar 16, which is forceped by the force-applying component 17, slides towards the side (front) in the sliding direction. As a result, the cover 11 can be rotated from the open position to the closed position, thereby closing the pair of liquid inlets 9 with a pair of gates 11b.

[0103] As described above, in the cover unit 1 of this embodiment, by providing the cover opening and closing mechanism 12, it is possible to have a simple structure with fewer parts and to easily perform the opening and closing operation of the cover 11.

[0104] Therefore, in the lidded container 100 of this embodiment, by providing such a lid unit 1, the lid 11 can be easily opened and closed with one hand while holding the container body 2, thus further improving the ease of use.

[0105] Furthermore, as mentioned above, the liquid inlets 9 are positioned symmetrically, allowing the user to comfortably use either hand.

[0106] Furthermore, the present invention is not necessarily limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

[0107] For example, in the above embodiments, the present invention is illustrated in the case of a mug (beverage container) that has heat preservation and cold preservation functions through the container body 2 with the above-described vacuum insulation structure. However, the lid opening and closing mechanism 12 of the present invention can also be widely applied to lidded containers that have a container body and a lid unit that can be easily installed and removed from the container body.

Claims

1. A lid unit that is detachably installed relative to a container body with an upper opening, characterized in that, have: The lid body seals the upper opening of the container body and is provided with a liquid inlet; The cover, in a state where it is rotatably mounted on the cover body, allows for the opening and closing of the liquid inlet; and The cover opening and closing mechanism performs the opening and closing operation of the cover between the closed position where the cover closes the liquid inlet and the open position where the cover opens the liquid inlet. The cover opening and closing mechanism has a sliding rod that is slidably mounted on the cover body. The cover unit also includes a first magnet disposed on the cover body and a second magnet disposed on the slide rod. Utilizing the magnetic attraction formed between the first magnet and the second magnet that acts between the cover and the slide rod, the second magnet moves in the front-back direction in conjunction with the sliding operation of the slide rod, causing the first magnet to move in an arc around the rotation center of the cover, thereby causing the cover to rotate between the closed position and the open position.

2. The cover unit according to claim 1, characterized in that, With the bearing recess on one of the opposing surfaces of the cover body and the cover body engaged with the bearing protrusion on the other opposing surface of the cover body and the cover body, the cover body can be rotatably installed relative to the cover body.

3. The cover unit according to claim 1 or 2, characterized in that, The cover can be easily installed and removed from the cover body.

4. The cover unit according to claim 3, characterized in that, The cover body has a stop that prevents the cover from falling off in the closed position.

5. The cover unit according to claim 1 or 2, characterized in that, The cover opening and closing mechanism has a force-applying component that applies force to the slide rod on one side toward the sliding direction. By sliding the slide bar towards the opposite side of the sliding direction from the state where the liquid inlet is closed by the cover, overcoming the force applied by the force-applying component, the cover rotates from the closed position to the open position.

6. The cover unit according to claim 5, characterized in that, The lid opening and closing mechanism has an operating lever, which slides the slide bar while the handle portion provided on the side surface of the container body is held. The operating lever is configured to extend from the slide bar toward the side surface of the container body and the handle portion through a hole provided in the handle portion.

7. A container with a lid, wherein, have: The cover unit according to any one of claims 1 to 6; and The container body is for mounting the cover unit.

8. The lidded container according to claim 7, characterized in that, The container body has a vacuum insulation structure.
