Description

Technical Field

[0001] The present invention relates to a stopper unit and a beverage container.

Background Art

[0002] Some stopper units for beverage containers are provided with a lock mechanism for locking and unlocking the lid member relative to the stopper main body. For example, the lock mechanism for a beverage container disclosed in Patent Document 1 includes a swinging portion and a slide member. The swinging portion includes an engaging portion that engages with the lid member. The slide member is slidable up and down relative to the swinging portion. When the slide member is located at the lowermost position in the sliding range, the slide member comes into contact with a stopper provided on the stopper main body. Thereby, the slide member prohibits the swinging of the swinging portion. When the slide member slides upward from the lowermost position, the swinging portion becomes swingable.

The first pivot portion 46 and the second pivot portion 47 are positioned apart to the left and right. The first pivot portion 46 and the second pivot portion 47 each include a hole through which the pivot shaft 35 passes. The pivot shaft 35 extends in the left-right direction. The first pivot portion 46 and the second pivot portion 47 support the locking member 33 so that it can rotate around the pivot shaft 35 via the pivot shaft 35.

[0022] The locking retaining portion 45 includes a central recess 54, a first side recess 55, and a second side recess 56. The central recess 54 has an arc-shaped recess along the pivot support portion 39 of the locking member 33. The first side recess 55 has an arc-shaped recess along one end of the pivot shaft 35. The second side recess 56 has an arc-shaped recess along the other end of the pivot shaft 35. The lid member 11 includes a locking portion 57. The locking portion 57 is positioned above the locking retaining portion 45. The locking portion 57 has a claw-like shape that protrudes forward.

[0023] The sliding member 34 is mounted on the locking member 33 so as to be slidable vertically. By sliding vertically relative to the locking member 33, the sliding member 34 can move between a locked position and an unlocked position. In the locked position, the locking member 33 restricts its rotation. In the unlocked position, the locking member 33 releases its rotation.

[0024] The slide member 34 includes an operating section 60, a first slide section 61, a second slide section 62, and a regulating section 63. The operating section 60 is the part operated by the user's finger. The operating section 60 has a disc shape. As shown in Figure 8, the front surface 64 of the operating section 60 has a smooth shape without protrusions. The front surface 64 of the operating section 60 has a substantially flat shape. The front surface 64 of the operating section 60 may also have a slightly curved shape.

[0025] As shown in Figure 10, the back surface of the operating section 60 includes a plurality of reinforcing ribs 65. The reinforcing ribs 65 are arranged in a grid pattern. Note that in Figure 10, only some of the plurality of reinforcing ribs 65 are labeled with reference numerals, and the reference numerals for the other reinforcing ribs 65 are omitted.

[0026] The first slide portion 61 and the second slide portion 62 each protrude rearward from the back surface of the operating portion 60. The first slide portion 61 and the second slide portion 62 are positioned apart from each other in the left-right direction. The first slide portion 61 and the second slide portion 62 each extend in the vertical direction. The first slide portion 61 includes a first guide hole 66. The first guide hole 66 penetrates the first slide portion 61 in the left-right direction. The second slide portion 62 includes a second guide hole 67. The second guide hole 67 penetrates the second slide portion 62 in the left-right direction. The first guide hole 66 and the second guide hole 67 are elongated holes that extend in the vertical direction.

[0027] The first slide portion 61 is positioned through the first groove 41. The second slide portion 62 is positioned through the second groove 42. A pivot shaft 35 passes through the first guide hole 66 and the second guide hole 67. The slide member 34, together with the locking member 33, is supported by the plug body 10 via the pivot shaft 35. The slide member 34 is rotatable integrally with the locking member 33 around the pivot shaft 35. The pivot shaft 35 is movable relative to the slide member 34 along the guide holes 66 and 67. As a result, the slide member 34 is slidable up and down relative to the locking member 33.

[0028] As shown in Figure 9, the lock spring 36 is attached to the pivot shaft 35. The lock spring 36 contacts the lock member 33 and the lock holding portion 45. The pivot shaft 35 passes through the lock spring 36. The lock spring 36 biases the lock member 33 toward the locked position.

[0029] The restricting portion 63 is located at the lower end of the back of the operating portion 60. The restricting portion 63 protrudes rearward from the back of the operating portion 60. When the sliding member 34 is in the locked position, as shown in Figure 9, the restricting portion 63 is positioned within the notch 43 of the locking member 33.

[0030] As shown in Figure 8, the locking retainer 45 includes a first groove 72 and a second groove 73. The first groove 72 is located between the central recess 54 and the first side recess 55. The second groove 73 is located between the central recess 54 and the second side recess 56. The first groove 72 extends vertically along the first sliding portion 61. The second groove 73 extends vertically along the second sliding portion 62. Figure 11 is a cross-sectional view of the plug unit 3 in Figure 6 along line XI-XI. As shown in Figure 11, the first sliding portion 61 is located within the first groove 72. The second sliding portion 62 is located within the second groove 73.

[0031] As shown in Figures 7 and 8, the locking retaining portion 45 includes a stopper 71. The stopper 71 protrudes forward from the front surface of the plug body 10. The stopper 71 is positioned below the central recess 54. As shown in Figure 7, when the sliding member 34 is in the locked position, the restricting portion 63 of the sliding member 34 contacts the stopper 71, thereby restricting the rotation of the locking member 33.

[0032] Figure 12 is a longitudinal cross-sectional view of the slide member 34. The slide member 34 includes a first molded part 68 and a second molded part 69. The operating part 60 is composed of the first molded part 68 and the second molded part 69. The first molded part 68 includes the central part of the operating part 60, a first slide part 61, a second slide part 62, and a regulating part 63. The second molded part 69 surrounds the periphery of the first molded part 68. The second molded part 69 has a ring shape. The second molded part 69 surrounds the central part of the operating part 60 included in the first molded part 68.

[0033] The first molded part 68 and the second molded part 69 are integrally molded. For example, the first molded part 68 and the second molded part 69 are formed by two-color molding. The first molded part 68 and the second molded part 69 are made of different materials. For example, the second molded part 69 is made of a material with higher rigidity than the first molded part 68. Alternatively, the first molded part 68 may be made of a hard resin, and the second molded part 69 may be made of an elastic material such as an elastomer.

[0034] As shown in Figure 8, the lid member 11 includes an upper shield portion 75. The upper shield portion 75 protrudes forward from the front surface of the lid member 11. The plug body 10 includes a lower shield portion 76. The lower shield portion 76 protrudes forward from the front surface of the plug body 10. The upper shield portion 75 and the lower shield portion 76 surround the locking mechanism 14. The upper shield portion 75 covers the locking mechanism 14 from above. The lower shield portion 76 covers the locking mechanism 14 from below. The upper shield portion 75 and the lower shield portion 76 have an annular shape that surrounds the locking mechanism 14 in the vertical and horizontal directions.

[0035] As shown in Figure 4, in a side view of the plug unit 3, the front edge 77 of the upper shield portion 75 is inclined diagonally upward and rearward. That is, the height from the front of the plug body 10 in the portion of the upper shield portion 75 located above the slide member 34 is lower than the height from the front of the plug body 10 in the portion of the upper shield portion 75 located to the side of the slide member 34. In a side view of the plug unit 3, the upper edge 78 of the slide member 34 is exposed from the upper shield portion 75. Figure 13 is a top view of the plug unit 3 around the locking mechanism 14. As shown in Figure 13, in a top view of the plug unit 3, the upper edge 78 of the slide member 34 is exposed from the upper shield portion 75.

[0036] As shown in Figure 4, in a side view of the plug unit 3, the front edge 79 of the lower shield portion 76 is continuous with the front edge 77 of the upper shield portion 75 and is inclined diagonally upward and rearward. Figure 14 is a bottom view of the plug unit 3 around the locking mechanism 14. As shown in Figure 14, the lower shield portion 76 includes a recess 80 located below the slide member 34. In a top view of the plug unit 3, the lower edge 81 of the slide member 34 is exposed from the lower shield portion 76 through the recess 80.

[0037] Next, the operation of the locking mechanism 14 will be described. When the lid member 11 is closed, as shown in Figure 7, the locking member 33 is in the locked position and the sliding member 34 is in the locked position. When the locking member 33 is in the locked position, the locking portion 38 is locked to the locked portion 57. When the sliding member 34 is in the locked position, the restricting portion 63 is positioned facing the stopper 71. When the sliding member 34 is in the locked position, even if an attempt is made to rotate the locking member 33 and the sliding member 34, the restricting portion 63 will come into contact with the stopper 71. Therefore, the sliding member 34 and the locking member 33 cannot rotate around the pivot axis 35. The locked position is the uppermost position within the sliding range of the sliding member 34.

[0038] When a user opens the lid member 11, they first push down the slide member 34, sliding it downward relative to the lock member 33, thereby moving the slide member 34 from the locked position to the unlocked position. As shown in Figure 15, the unlocked position is located below the locked position. When the slide member 34 is in the unlocked position, the regulating part 63 is separated downward from the stopper 71. Therefore, as shown in Figure 16, the slide member 34 and the lock member 33 become rotatable around the pivot axis 35.

[0039] The user can rotate the slide member 34 and the locking member 33 around the pivot axis 35 by pressing the slide member 34 with their finger. As the slide member 34 and the locking member 33 rotate around the pivot axis 35, the locking member 33 moves from the locked position to the unlocked position. This releases the locking portion 38 from the locked portion 57, and the locking member 33 opens the lid member 11. The opened lid member 11 rotates in the direction of opening the drinking spout 18 due to the elastic force of the hinge spring 24. As a result, the lid member 11 is in the open state shown in Figure 5.

[0040] As shown in Figure 8, the front surface 64 of the operating section 60 includes a mark 82 indicating the pressing position. As shown in Figure 15, the mark 82 is located below the pivot axis 35 of the locking member 33 when the slide member 34 is in the unlocked position. The mark 82 has a recessed shape from the front surface of the slide member 34. The front surface 64 of the operating section 60 has a smooth shape without any irregularities except for the recess of the mark 82. The user can easily open the lid member 11 with little force by pressing the operating section 60 at the mark 82.

[0041] When the user releases pressure on the slide member 34, the lock member 33 and the slide member 34 rotate in the opposite direction due to the elastic force of the lock spring 36. As a result, as shown in Figure 17, the lid member 11 is in the open position and the lock member 33 returns to the locked position. The slide member 34 is in the unlocked position. Therefore, the slide member 34 and the lock member 33 are rotatable around the pivot axis 35.

[0042] When the user closes the lid member 11, the locked portion 57 rides up onto the locked portion 38 against the elastic force of the lock spring 36. This causes the lock member 33 to rotate toward the locked position. As the locked portion 57 overcomes the locked portion 38, the lock member 33 returns to the locked position due to the elastic force of the lock spring 36. As a result, the locked portion 38 engages with the locked portion 57, similar to the state shown in Figure 15, and the lid member 11 becomes closed.

[0043] The user pushes up the slide member 34, sliding it upward relative to the lock member 33, thereby moving the slide member 34 from the unlocked position to the locked position, similar to the state shown in Figure 7. This restricts the rotation of the lock member 33.

[0044] In the stopper unit 3 for the beverage container 1 described above, the front surface 64 of the sliding member 34 has a smooth shape without any protrusions. Therefore, even if the beverage container 1 tips over or falls and the sliding member 34 is subjected to an impact, damage to the sliding member 34 is suppressed.

[0045] The front surface 64 of the slide member 34 has a smooth shape without protrusions, but the upper edge 78 of the slide member 34 is exposed from the upper shield portion 75. Therefore, as shown in Figure 18, the user can easily push down the slide member 34 by placing their finger on the upper edge 78 of the slide member 34.

[0046] Furthermore, although the front surface 64 of the slide member 34 has a smooth shape without protrusions, the lower edge 81 of the slide member 34 is exposed from the lower shield portion 76. Therefore, as shown in Figure 19, the user can easily push up the slide member 34 by placing their fingers on the lower edge 81 of the slide member 34.

[0047] Reinforcing ribs 65 are provided on the back of the slide member 34. Therefore, even if the slide member 34 is subjected to impact due to the beverage container 1 tipping over or falling, damage to the slide member 34 is further suppressed. In addition, the slide member 34 is formed by integrally molding a first molded part 68 and a second molded part 69. This further suppresses damage to the slide member 34 even if it is subjected to impact.

[0048] Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the spirit of the invention.

[0049] For example, the structure of the stopper body 10 is not limited to that of the above embodiment and may be modified. The structure of the lid member 11 is not limited to that of the above embodiment and may be modified. The structure of the first packing unit 12 is not limited to that of the above embodiment and may be modified. The structure of the second packing unit 13 is not limited to that of the above embodiment and may be modified.

[0050] The structure of the locking mechanism 14 is not limited to that of the above embodiment and may be modified. For example, the shape of the operating part 60 is not limited to a disc shape, but may be a square or other shape. The mark 82 is not limited to a recess, but may be formed by printing or a sticker. Alternatively, the mark 82 may be omitted. The shape of the reinforcing rib 65 is not limited to that of the above embodiment and may be modified. Alternatively, the reinforcing rib 65 may be omitted. The slide member 34 may be formed from a single material. [Industrial applicability]
