Embodiments of the present invention will be described with reference to the drawings.
1 to 4, the beverage server 1 includes a heat-resistant glass container 2, a dripper 3 that is detachably fitted to the container, and a lid 4.

  The container 2 comprises a side wall 6 having a substantially circular cross section with an opening 5 above. The side wall 6 of the container is provided with a flange 7 and a spout 8 having a reduced inner diameter at the top. The spout 8 is constituted by a groove 9 formed on the inside by causing a part of the side wall 6 to bulge outward in the radial direction in a substantially V-shaped cross section. The groove portion 9 extends in the vertical direction on the inner side of the side wall 6 from the upper edge of the container 2 to a position below the flange portion 7. The handle 10 of the container 2 has an upper end connected to the side wall 6 near the upper edge of the container 2, and extends almost horizontally outwardly from the side wall 6, then curves downward, and a lower end is a lower outer side of the side wall 6. Connect to one.

  The entire dripper 3 has a conical cylinder shape that shrinks downward, and is detachably fitted into the opening 5 of the container 1. The dripper 3 includes a frame body 11 integrally formed of a synthetic resin, and a metal mesh 12 that is insert-molded together with the frame body 11. The frame 11 includes an annular frame 13, a knob 14, and a support bone 15.

  The upper annular frame 13 has an annular shape and has a flange portion that is placed on the upper edge of the container 2. The knob 14 extends horizontally from the flange portion of the annular frame 13 outward in the radial direction. The six support bones 15 extend downward in a spiral manner from the annular frame 13 at equal intervals in the circumferential direction, converge at the lower end, and are integrally connected to each other.

  On the outer periphery of the dripper 3, engaging projections 16 projecting outward in the radial direction are formed in the middle portion and the same height position of the three support bones 15 positioned at intervals of 120 °. As shown in FIG. 5 (a), the engaging projections 16 are only provided when one of them is disposed in the spout 8 and the dripper 3 is inserted into the opening 5 of the container 2. 7 are arranged in a mutual relationship that allows passage in the vertical direction. Then, after the engaging protrusion 16 passes through the flange portion 7 and the annular frame 13 is placed on the upper edge of the container 2, the dripper 3 is rotated horizontally, as shown in FIG. When one engaging protrusion 16 is shifted from the position corresponding to the spout 8, the dripper 3 is prevented from coming upward by the engaging protrusion 16.

  The lid 4 is coupled to the container 2 via a hinge 18 coupled to the upper part of the handle 10 so that the opening 5 of the container 2 and the opening 17 of the dripper 3 can be opened and closed. The lid 4 is integrally formed of a synthetic resin, and includes a disk-shaped main body portion 19, an engaging claw 20 formed on the peripheral edge portion thereof, and a finger hook piece 21. The engaging claw 20 is curved and extends slightly downward along the periphery of the main body 19, and can be elastically engaged with the annular frame 13 of the dripper 3. The engaging claw 20 is missing at a part of the outer periphery of the main body 19 and a notch 22 is provided. The finger-hanging piece 21 is inclined and extended so as to rise radially outward from the peripheral edge of the main body 19.

  The bracket 23 and the shaft portion 24 constituting a part of the hinge 18 are formed so as to extend downward from the finger hanging piece 21. A pair of shaft portions 24 protrude from the opposing inner surface of the bracket 23, and each has a long cylindrical shape. A bearing member 25 constituting another part of the hinge 18 is fixed to the handle 10 of the container 2. The bearing member 25 detachably receives the pair of shaft portions 24 and supports them rotatably.

  As shown in FIGS. 7 to 9, the bearing member 25 is integrally formed of an elastic synthetic resin, and the first and second bearing portions 26 and 27 and a belt-like portion 28 that connects between these bearing portions 26 and 27. It comprises. The first and second bearing portions 26 and 27 are integrally coupled to each other on the handle 10 of the container to form a bearing. One bearing portion 27 includes an engagement piece 29 that engages with the upper edge portion of the container 2. The belt-like portion 27 is configured to wind the handle 10 in a state where the bearing portions 26 and 27 are engaged with each other. The handle 10 has a relatively large dimensional error in manufacturing, but the belt-like portion 28 is designed in consideration of this dimensional error. Even when the fastening of the handle 10 by the belt-like portion 28 is weak, the engagement piece 29 engages with the upper edge of the container 2, so that the bearing member 25 is securely fixed on the handle 10.

  When the beverage server 1 is used, one engaging protrusion 16 of the dripper 3 is formed in the groove portion 9 (spout 8) of the container 2 with the lid 4 raised, as shown in FIG. When the dripper 3 is fitted to the container 2 at the relative rotation angle position corresponding to, the three engaging protrusions 16 pass through the flange portion 7 and are disposed below the flange portion 7. In this state, when the dripper 3 is rotated clockwise to the position shown in FIG. 5B (to the vicinity of the position where the knob contacts the hinge 18 in the illustrated embodiment), the dripper 3 is prevented from being detached from the container 2. The For example, after putting coffee powder into the dripper 3, pouring a predetermined amount of hot water and extracting coffee, if the lid 4 is turned over and pressed without removing the dripper 3, the engaging claw 20 is connected to the annular frame 13 of the dripper 3. And the lid 4 is prevented from opening. In the illustrated embodiment, if the dripper 3 is rotated clockwise to a predetermined position, the knob 14 corresponds to the cutout portion 22 of the lid 4 so that the lid 4 can be closed. The knob 14 cannot contact the engaging claw 20 of the lid 4 to close the lid 4. If the container 2 is tilted with the lid 4 closed, the coffee can be poured out from the spout 8. Even when the container 2 is inclined, the dripper 3 does not fall out of the container 2 because the engaging protrusion 16 is engaged with the flange portion 7. Further, since the dripper 3 has a conical shape, when the container 2 is tilted, the coffee flow is not blocked. Since the lid 4 is closed, the coffee powder is not exposed and the appearance is not impaired, and the coffee powder does not fall down. Since no metal parts are used for the container 2 and the lid 3, the coffee can be reheated in a microwave oven with the dripper 3 removed and the lid 4 closed. Since the dripper 3 has a simple conical cylinder shape, cleaning is easy. The lid 4 can also be removed from the container 2 and easily cleaned. The container 2 and the dripper 4 can be stored in a compact state.
