[0014] Hereinafter, embodiments of the beverage container of the present invention will be described with reference to the drawings. The beverage container of the first and second embodiments has an insulating part formed with a hollow structure and a double wall part, and has excellent insulating properties. [First embodiment]

[0015] A beverage container 11 according to a first embodiment will be described with reference to Figures 1 to 3. The beverage container 11 comprises a first container portion 13 which constitutes the outer shell of the beverage container 11 and has an opening 12, a second container portion 14 which is provided inside the first container portion 13, a heat insulating portion 15 which is interposed between the first container portion 13 and the second container portion 14, a lid body 16 which covers the opening 12, a filter portion 17 which is provided in a part of the lid body 16, and a packing portion 18 which is provided integrally with the filter portion 17.

[0016] As shown in Figs. 1 to 3, the first container portion 13 is concave and cylindrical with a bottom. The first container portion 13 is integrally formed from a light-transmitting material, for example, heat-resistant glass. The opening 12 is trumpet-shaped and gradually widens toward the end. The first container portion 13 has a step portion 21 that protrudes inward. The step portion 21 is provided at a position spaced a predetermined length (for example, several centimeters) from the opening 12, and protrudes inward from the inner surface of the first container portion 13 in a step shape. The step portion 21 has an inner end portion 21A that is located at its innermost position. The dimension of the step portion 21 in the radial direction of the first container portion 13 is, for example, 1 to 10 mm.

[0017] The second container part 14 is concave and has a cylindrical shape with a bottom. The second container part 14 is accommodated inside the first container part 13. The second container part 14 is integrally formed, for example, from a light-transmitting material, for example, heat-resistant glass. The second container part 14 extends from the step part 21, and is integrally formed with the first container part 13 at the inner end part 21A of the step part 21. The heat insulating part 15 is formed as a cavity provided between the first container part 13 and the second container part 14. The thickness dimension of the heat insulating part 15 is about 1 to 10 mm. The cavity constituting the heat insulating part 15 is filled with, for example, air.

[0018] Hot water used for brewing tea can be stored together with tea leaves in the second container 14. The shape of the first container 13 and the second container 14 may be a cylindrical shape with a bottom or a polygonal shape with a bottom. The first container 13 and the second container 14 are formed of translucent heat-resistant glass, but the material is not limited to this. The first container 13 and the second container 14 may be formed of a metal material such as opaque stainless steel, a ceramic material such as pottery, or a synthetic resin material.

[0019] The lid body 16 is configured to be able to cover the opening 12 and be detachable from the opening 12. The lid body 16 is formed, for example, in a stepped disk shape. The diameter of the lid body 16 is, for example, smaller than the diameter of the opening 12 of the first container part 13. As shown in FIG. 2, when the lid body 16 is attached to the first container part 13 (covering the opening 12), a spout 22 is provided in the gap between the lid body 16 and the first container part 13 (opening 12). The spout 22 is provided on the entire circumference of the lid body 16, and a user can pour a beverage into a cup or the like from any angle. The lid body 16 is formed, for example, from a metal material such as stainless steel, but the material is not limited thereto. The lid body 16 may be formed from a synthetic resin material.

[0020] The lid 16 has a disk-shaped lid body 23 and a cylindrical projection 24 projecting from the lid body 23. The lid body 23 is, for example, frustum-shaped with a diameter increasing toward the top. The diameter of the projection 24 is configured to be smaller than the diameter of the lid body 23. The projection 24 projects from the lid body 23 toward the inside of the first container portion 13. The lid body 23 may be formed in a polygonal plate shape. The projection 24 may be formed in a polygonal prism shape. The lid 16 does not have to have a stepped structure.

[0021] The filter section 17 is a so-called tea strainer. For example, the filter section 17 can remove only tea leaves from tea brewed in the second container section 14 and pour the tea into a cup (not shown). The filter section 17 constitutes the lower part of the lid body 16, i.e., the part that is inserted into the first container section 13.

[0022] The filter part 17 is cylindrical and has a plurality of through holes (not shown). The filter part 17 is fitted to the outside of the protrusion 24 and fixed to the cover 16. The filter part 17 is made of a metal material such as stainless steel. The filter part 17 is made, for example, by forming a plurality of through holes in a flat metal plate by etching (corrosion processing) or punching by pressing, and further bending the plate into a cylindrical shape. The diameter of the through holes is, for example, about 0.5 to 2 mm. The shape of the through holes may be circular or may be a shape other than circular. The filter part 17 may be made of a resin material.

[0023] Also, the filter section 17 may be omitted. In that case, the packing section 18 may be provided at the lower end of the protrusion 24 of the lid body 16, and a liquid passage hole may be provided in the protrusion 24 of the lid body 16 inside the packing section 18, so that the liquid in the beverage container 11 can be poured into a cup through the liquid passage hole and the spout 22.

[0024] The filter unit 17 has an attachment portion 25 for attaching the packing unit 18 to the outer peripheral surface of the end (lower end) opposite the lid body 16. The attachment portion 25 has, for example, a "C" shaped cross section, but is not limited thereto. The attachment portion 25 may have any structure as long as it is capable of holding the packing unit 18. The packing unit 18 is fixed to the filter unit 17 by being fitted into the attachment portion 25 (for example, the inside of the attachment portion 25).

[0025] As shown in FIG. 3, the packing portion 18 is formed in an annular shape surrounding the outer peripheral surface of the filter portion 17. The packing portion 18 is provided integrally with the filter portion 17, but is detachable from the mounting portion 25. The packing portion 18 is formed, for example, from a rubber-like elastic body. The packing portion 18 has a flexible flange portion 18A that protrudes annularly toward the outside. As shown in FIG. 3, the flange portion 18A has a thin disk shape, and as shown in FIG. 2, it is bent along the inner surface of the first container portion 13 and is in close contact with the inner surface of the first container portion 13, thereby stopping water at this position.

[0026] The packing portion 18 is provided at a position equal to the inner end 21A of the step portion 21 or outside the inner end 21A of the step portion 21. As shown in Figures 2 and 3, the packing portion 18 is configured to be able to abut against the step portion 21 at a position equal to the inner end 21A of the step portion 21 or outside the inner end 21A of the step portion 21, or to be separated from the step portion 21. Therefore, with the lid 16 covering the opening 12, the inner surface of the filter portion 17 is approximately flush with the inner surface of the second container portion 14.

[0027] Next, a method for manufacturing the beverage container of this embodiment will be described with reference to Figs.

[0028] In a first step, as shown in Fig. 4, part 32 constituting the second container part is placed on top of part 31 constituting the first container part. At this time, part 32 constituting the second container part includes a part that will eventually become the vicinity of opening 12 of first container part 13 and step part 21.

[0029] In this manner, with part 32 constituting the second container part stacked on top of part 31 constituting the first container part, in the second step, as shown in Figure 5, these abutting parts (near step 21) are heated, for example with a burner or the like, to weld them together (welding if they are made of a metal material, firing in a joined state if they are made of a ceramic material, or gluing if they are made of a synthetic resin material), thereby manufacturing an integrated beverage container 11.

[0030] The operation of the beverage container of this embodiment will be described with reference to Fig. 6. In this embodiment, since the packing portion 18 is adapted to abut against the step portion 21 outside the inner end portion 21A of the step portion 21, the inner surface of the filter portion 17 and the inner surface of the second container portion 14 are substantially flush with each other. Therefore, when the beverage extracted in the beverage container 11 is poured into a cup or the like, the packing portion 18 does not become like a dam, and the beverage is prevented from remaining in the beverage container 11.

[0031] In addition, because the connection points between the first container portion 13 and the second container portion 14 are minimized via the step portion 21 and the insulating portion 15 is interposed between them, even when hot water is poured into the beverage container 11, the temperature of the second container portion 14 is prevented from being conducted to the first container portion 13 as much as possible. This allows the beverage container 11 to omit a handle, and the user can hold the beverage container 11 without stress and pour the beverage into the cup from any angle of the spout 22 located all around the circumference.

[0032] According to this embodiment, the following can be said: The beverage container 11 comprises a first container part 13 having an opening 12 and a step part 21 that is provided at a position spaced a predetermined length from the opening 12 and protrudes inward, a second container part 14 that extends from the step part 21 and is provided inside the first container part 13, a heat insulating part 15 that is interposed between the first container part 13 and the second container part 14, a lid body 16 that can cover the opening 12 or be separated from the opening 12 and that forms a spout 22 in a gap with the first container part 13 when the lid body 16 covers the opening 12, and a packing part 18 that is provided integrally with the lid body 16 and that is configured to be able to abut against the step part 21 at a position equal to an inner end part 21A of the step part 21 or be able to be separated from the step part 21.

[0033] According to this configuration, the packing portion 18 can abut against the step portion 21 at a position equal to or outside the inner end 21A of the step portion 21, so that the packing portion 18 does not protrude inward beyond the inner end 21A. Therefore, when the beverage container 11 is turned sideways to pour the beverage inside, the packing portion 18 does not become like a dam, and the packing portion 18 can prevent the liquid from remaining in the beverage container 11. This allows the user to use the beverage container 11 without feeling stressed. In addition, since the beverage container 11 has a double-wall structure having the insulating portion 15, the first container portion 13 does not heat up even when a hot beverage is poured into the beverage container 11. Therefore, the handle can be omitted from the beverage container 11, and the manufacturing cost can be reduced. In addition, the user can hold any part of the first container portion 13 without stress, and pour the beverage into the cup in that state.

[0034] In this case, the lid body 16 has a cylindrical filter portion 17, and the packing portion 18 is provided integrally with the filter portion 17. With this configuration, even when the filter portion 17 is provided on the lid body 16, it is possible to prevent liquid from remaining in the beverage container 11.

[0035] In this case, spout 22 is provided around the entire circumference of lid 16. This configuration allows the spout to be secured at 360°, resulting in beverage container 11 that users can use without stress. Also, a handle can be omitted from beverage container 11. Also, compared to providing spout 22 in one location in a later process, the number of processing steps can be reduced. As a result, manufacturing costs can be reduced.

[0036] The heat insulating section 15 is filled with air. With this configuration, the heat insulating section 15 can be realized at a lower cost than when a heat insulating material, heat storage material, or ice pack is separately filled in the heat insulating section 15, and an increase in the weight of the beverage container 11 can be prevented compared to when a heat storage material or the like is filled in the heat insulating section 15.

[0037] In the following embodiment, differences from the above embodiment will be mainly described, and illustrations or descriptions of parts common to the above embodiment will be omitted. [Second embodiment]

[0038] A beverage container 11 according to a second embodiment will be described with reference to Figures 7 and 8. In this embodiment, the first container portion 13 has a spout 22 near the opening 12. In this embodiment, the spout 22 is not covered by the lid body 16, and a user can pour a beverage into a cup or the like through this spout 22. As an example, the diameter of the lid body 16 is smaller than the diameter of the opening 12 of the first container portion 13, but the diameter of the lid body 16 may be larger than the diameter of the opening 12 of the first container portion 13.

[0039] The packing portion 18 is configured to be able to abut against the step portion 21 at a position equal to the inner end portion 21A of the step portion 21 or outside the inner end portion 21A of the step portion 21, or to be separated from the step portion 21.

[0040] Even when spout 22 is formed at one location on opening 12 as in this embodiment, packing portion 18 can abut step portion 21 at a position equal to inner end 21A of step portion 21 or outside inner end 21A. This prevents packing portion 18 from protruding inward beyond inner end 21A. Therefore, when beverage container 11 is turned on its side to pour the beverage inside, packing portion 18 does not become like a dam, and it is possible to prevent liquid from remaining in the container due to packing portion 18. This allows the user to use beverage container 11 without feeling stressed. [Third embodiment]

[0041] A beverage container 11 according to a third embodiment will be described with reference to Figures 9 and 10. In this embodiment, the second container portion 14 is omitted.

[0042] The first container portion 13 is concave and cylindrical with a bottom. The first container portion 13 is integrally formed from a light-transmitting material, for example, heat-resistant glass. The opening 12 is trumpet-shaped and gradually widens toward the end. In this embodiment, the first container portion 13 has a step portion 21 on the way from the opening 12 to the bottom. The first container portion 13 is formed from light-transmitting heat-resistant glass, but the material is not limited to this. The first container portion 13 may be formed from a metal material such as opaque stainless steel, a ceramic material such as pottery, or a synthetic resin material.

[0043] The step 21 is provided at a position a predetermined length (e.g., several centimeters) away from the opening 12, and protrudes inward in a stepped manner from the inner surface of the first container portion 13. The step 21 has an inner end portion 21A located at its innermost position. The dimension of the step 21 in the radial direction of the first container portion 13 is, for example, 1 to 10 mm.

[0044] The lower portion of the first container portion 13 extends downward from the inner end portion 21A. Therefore, in this embodiment, the step portion 21 is provided at a midpoint in the up-down direction of the first container portion 13. The lower portion of the first container portion 13 has, for example, a handle 33.

[0045] The packing portion 18 is configured to be able to abut against the step portion 21 at a position equal to the inner end portion 21A of the step portion 21 or outside the inner end portion 21A of the step portion 21, or to be separated from the step portion 21.

[0046] The operation of the beverage container 11 of this embodiment will be described with reference to Figures 9 and 10. In this embodiment as well, the packing portion 18 abuts against the step portion 21 outside the inner end portion 21A of the step portion 21, so that the inner surface of the filter portion 17 and the lower portion of the first container portion 13 are substantially flush with each other. Therefore, when the beverage extracted in the beverage container 11 is poured into a cup or the like, the packing portion 18 does not become like a dam, and the beverage is prevented from remaining in the beverage container 11.

[0047] According to this embodiment, the following can be said: Beverage container 11 comprises first container part 13 having opening 12 and step part 21 that is provided at a position a predetermined length away from opening 12 and protrudes inward, lid body 16 that can cover opening 12 or be separated from opening 12 and that forms a spout 22 in a gap with first container part 13 when covering opening 12, and packing part 18 that is provided integrally with lid body 16 and that is configured to be able to abut against step part 21 at a position equal to inner end part 21A of step part 21 or outside inner end part 21A of step part 21 or be able to be separated from step part 21.

[0048] According to this configuration, since the packing portion 18 can come into contact with the step portion 21 at a position equal to or outside the inner end portion 21A of the step portion 21, the packing portion 18 does not protrude inward beyond the inner end portion 21A. Therefore, when the beverage container 11 is turned on its side to pour the beverage inside, the packing portion 18 does not become like a dam, and it is possible to prevent the packing portion 18 from causing liquid to remain in the beverage container 11. This allows the user to use the beverage container 11 without feeling any stress.

[0049] In this case, the lid body 16 has a cylindrical filter portion 17, and the packing portion 18 is provided integrally with the filter portion 17. With this configuration, even when the filter portion 17 is provided on the lid body 16, it is possible to prevent liquid from remaining in the beverage container 11.

[0050] The above-described embodiment can be implemented with various substitutions and modifications. Of course, the above-described different embodiments can be appropriately combined to form one invention. [Explanation of symbols]
