DETAILED DESCRIPTION OF THE INVENTION

[0008] Beverage containers according to embodiments will be described in detail below with reference to the drawings.

[0009] In order to facilitate understanding of the invention, the position, size, shape, range, etc. of each component shown in the following drawings may not represent the actual position, size, shape, range, etc. Therefore, the present invention is not necessarily limited to the position, size, shape, range, etc. disclosed in the drawings, etc. In the embodiments, elements expressed in the singular include the plural unless otherwise clearly indicated in the context. First Embodiment Fig. 1 is a perspective view showing a beverage container according to a first embodiment, and Fig. 2 is a side cross-sectional view of the beverage container according to the first embodiment. The beverage container 10 of the first embodiment has a container body 1 and a lid portion 2.

[0010] The container body 1 is, for example, a cylindrical, vacuum double-walled structure with a bottom, and includes a storage section 11 for storing a beverage, and an opening (drinking spout) 12 through which the beverage flows out of the storage section 11. A threaded section 13 that threads onto the lid section 2 is provided on the outer side of the opening 12, slightly below the plane of the drawing. In addition, a constricted section 14 is provided between the storage section 11 and the opening 12, with a flow path that is narrower than the storage section 11 and the opening 12. The container body 1 may be made of, for example, stainless steel.

[0011] The lid portion 2 has an outer lid 21, a first insulating material 22, a stainless steel ring 23, an upper part of the inner plug (first part) 24, a gasket 25, a second insulating material 26, a lower part of the inner plug (second part) 27, and a gasket 28. Fig. 3 is a development view of the lid of the first embodiment, Fig. 4 is a cross-sectional view of the development view shown in Fig. 3, and Fig. 5 is a side cross-sectional view illustrating the lid of the first embodiment. The outer lid 21 covers the opening 12. The material of the outer lid 21 is not particularly limited, but may be, for example, a resin such as polypropylene. As shown in FIGS. 4 and 5, the outer lid 21 has an insertion portion 21a, a welding assistant portion 21b, and a screw-engagement portion 21c. The insertion portion 21a is disposed inside the outer lid 21 at a position corresponding to a stainless steel arrangement portion of the inner plug upper portion 24, which will be described later, and protrudes from the inside of the top plate of the outer lid 21.

[0012] The welding assistant portion 21b is disposed so as to protrude from the inside of the top plate of the outer lid 21. This welding assistant portion 21b functions to align the stainless steel ring placement portion 24b by sandwiching the insertion portion 21a and the inner side wall of the stainless steel ring placement portion 24b. The welding assistant portion 21b may also support a portion of the side of the first insulating material 22 to restrict movement of the first insulating material 22 in the lateral direction of the page. The threaded portion 21c is disposed on the inner side of the outer lid 21. The threaded portion 21c is threadably engaged with the threaded portion 13.

[0013] The first insulating material 22 and the second insulating material 26 suppress temperature changes (keeps beverages cold or hot) stored in the container body 1. The shape of the first insulating material 22 is formed to correspond to the shape of the insulating material storage section (described next) provided in the inner plug upper portion 24. In this embodiment, it is cylindrical. The shape of the second insulating material 26 is formed to correspond to the shape of the insulating material storage section (described later) provided in the inner plug upper portion 27. In this embodiment, it is cylindrical.

[0014] The inner plug upper portion 24 has a heat insulating material storage portion 24a, a stainless steel ring arrangement portion 24b, a fitted portion 24c, and a first packing arrangement portion 24d. The constituent material of the inner plug upper portion 24 is not particularly limited, but examples include resins such as polypropylene. The heat insulating material storage section 24a has a cylindrical shape with a bottom.

[0015] The stainless steel ring placement portion 24b has a groove provided so as to surround the open end of the upper surface of the heat insulating material storage portion 24a. The stainless steel ring 23 is placed in this stainless steel ring placement portion 24b.

[0016] This inner plug upper part 24 is fixed to the outer lid 21 by a stainless steel ring 23. Specifically, the stainless steel ring 23 is placed in the stainless steel ring placement part 24b, and with the insertion part 21a inserted, heat is generated in the stainless steel ring 23 by electromagnetic induction, melting the resin in the stainless steel ring placement part 24b around the stainless steel ring 23 and welding the inner plug upper part 24 to the insertion part 21a. In addition, by welding the welding assistant part 21b as well, the area of ​​the resin to be welded (welded area) can be increased. The space surrounded by the outer lid 21 and the insulation material storage part 24a is an example of a first hollow part. A first insulation material 22 is placed in this space. FIG. 6 is a perspective view illustrating the cover of the first embodiment.

[0017] The fitted portion 24c has a portion 241c formed by cutting out a part of the bottom of the heat insulating material storage portion 24a, and a flat claw receiving portion 242c provided outside the cutout. The shape of the fitted portion 24c is provided to correspond to the shape of the fitting portion described later. The claw portion described later is disposed in the claw receiving portion 242c. Returning to FIG. 4, the explanation will be given again. The first packing placement portion 24d has a groove provided so as to surround the open end of the lower surface of the heat insulating material storage portion 24a. The packing 25 mainly prevents liquid from flowing into the heat insulating material storage portion 24a.

[0018] The inside plug lower part 27 has a heat insulating material storage part 27a, a fitting part 27b, and a second packing arrangement part 27c. The material of the inside plug lower part 27 is not particularly limited, but may be, for example, a copolyester resin.

[0019] The heat insulating material storage section 27a is cylindrical. The second heat insulating material 26 is disposed inside the heat insulating material storage section 27a. As shown in Fig. 5, the diameter of the second heat insulating material 26 is formed to be slightly smaller than the diameter of the heat insulating material storage section 27a.

[0020] The fitting portion 27b is disposed so as to protrude from the upper portion of the heat insulating material storage portion 27a, and is formed integrally with the heat insulating material storage portion 27a. The fitting portion 27b is tubular with a partially opened (notched) side. The open end of the fitting portion 27b is provided with a claw portion 271b that protrudes outward.

[0021] As shown in Figure 6, this claw portion 271b is inserted into portion 241c and fitted into claw receiving portion 242c. Fitting of claw portion 271b into claw receiving portion 242c creates a so-called fixed fit, making it difficult to separate claw portion 271b from claw receiving portion 242c. Furthermore, the length H1 of the longitudinal arc of portion 241c is approximately the same as or slightly longer than the length H2 of the longitudinal arc of fitting portion 27b. Therefore, fitting of claw portion 271b into claw receiving portion 242c functions as a rotation stopper for center plug lower portion 27 relative to center plug upper portion 24. The fitting portion 27b has a cylindrical shape with a part of the side open, which makes it easy to fit the claw portion 271b into the claw receiving portion 242c. Returning to FIG. 5, the explanation will be given again.

[0022] Second insulating material 26 is surrounded by the bottom of insulating material housing portion 24a and support portion 271a at the bottom of insulating material housing portion 27a. The space surrounded by the bottom of insulating material housing portion 24a and insulating material housing portion 27a is an example of a second hollow portion. In addition, although a gap 27d is formed between the lower part of the second heat insulating material 26 and the lower part of the heat insulating material storage portion 27a in FIG. 5, the gap 27d may be omitted.

[0023] Second packing arrangement portion 27c is arranged in a region surrounding the lower side surface of inside plug lower portion 27. In this embodiment, packing 28 that stops the flow of beverage in reservoir 11 is attached to second packing arrangement portion 27c so that it cannot be removed.

[0024] The material of the packings 25 and 28 is not particularly limited, but examples thereof include silicone rubber and thermoplastic elastomer.

[0025] When the lid part 2 is attached to the container body 1, the packing 28 is located on the side of the narrowed part 14, and stops the beverage in the reservoir part 11 from entering above the packing 28.

[0026] As described above, the beverage container 10 of the embodiment comprises a bottomed cylindrical container body 1 having an opening 12, a threaded portion 13 provided on the outside of the opening 12, and a storage portion 11 in which the beverage is stored; an outer lid 21 having a threaded portion 21c that threadably engages with the threaded portion 13 and covers the opening 12; an upper stopper portion 24 that forms a first hollow portion by being joined to the outer lid 21; a lower stopper portion 27 that has a gasket 28 that seals the beverage and is attached to the upper stopper portion 24 to form a second hollow portion separated from the first hollow portion; and a first insulating material 22 and a second insulating material 26 that are arranged in the first hollow portion and the second hollow portion, respectively.

[0027] By providing the first insulating material 22 and the second insulating material 26 and dividing the insulating layer into two layers, it is possible to reduce the thermal conductivity from the top of the storage part 11 to the outside of the lid part 2 and to suppress the flow of air, thereby improving the heat retention performance.

[0028] Furthermore, by forming the center plug upper part 24 and the center plug lower part 27 as separate parts rather than being integrally molded, the outer lid 21 and the center plug upper part 24 can be formed from a resin such as polypropylene, and the center plug lower part 27 can be formed from a copolyester resin. This allows for lower costs compared to when the outer lid 21, the center plug upper part 24, and the center plug lower part 27 are all formed from a copolyester resin, or when the center plug upper part 24 and the center plug lower part 27 are all formed from a copolyester resin.

[0029] Furthermore, center plug lower part 27 has insulation material storage section 27a that stores second insulation material 26 and fitting section 27b that protrudes from the end of insulation material storage section 27a, and fitting section 27b fits into fitted section 24c that is formed by cutting out a portion of the bottom of insulation material storage section 24a and has area 241c that is provided to correspond to the shape of fitting section 27b. This structure makes it difficult for center plug upper part 24 and center plug lower part 27 to be disassembled, and also functions as a rotation stopper for center plug lower part 27c. <Second embodiment> Figure 7 is a perspective view showing a beverage container according to a second embodiment, and Figure 8 is a side cross-sectional view of the beverage container according to the second embodiment. The beverage container 10 a of the second embodiment has a container body 3 and a lid portion 4 .

[0030] The container body 3 is, for example, a cylindrical, vacuum double-walled structure with a bottom, and includes a storage section 31 for storing a beverage, and an opening (drinking spout) 32 through which the beverage flows out of the storage section 31. A threaded portion 33 that threads onto the lid 4 is provided on the inside of the opening 32, slightly below the plane of the drawing. In addition, a constricted section 34 is provided between the storage section 31 and the opening 32, with a flow path that is narrower than the storage section 31 and the opening 32. The container body 3 may be made of stainless steel, for example.

[0031] The lid portion 4 has an outer lid 41, a first insulating material 42, a stainless steel ring 43, an upper part of the inner plug (first part) 44, a packing 45, a second insulating material 46, and a lower part of the inner plug (second part) 47.

[0032] Figure 9 is a development view of the lid of the second embodiment, Figure 10 is a cross-sectional view of the development view shown in Figure 9, and Figure 11 is a side cross-sectional view illustrating the lid of the second embodiment. The outer lid 41 covers the opening 32. The material of the outer lid 41 is not particularly limited, but may be, for example, a resin such as polypropylene. As shown in FIGS. 10 and 11, the outer lid 41 has an insertion portion 41a and a welding assistant portion 41b. The insertion portion 41a is disposed inside the outer lid 41 at a position corresponding to a stainless steel arrangement portion of the inner plug upper portion 44, which will be described later, and protrudes from the inside of the top plate of the outer lid 41.

[0033] The welding assistant portion 41b is disposed so as to protrude from the inside of the top plate of the outer lid 41. This welding assistant portion 41b functions to align the stainless steel ring placement portion 44b by sandwiching the insertion portion 41a and the inner side wall of the stainless steel ring placement portion 44b. The welding assistant portion 41b may also support a portion of the side of the first insulating material 42 to restrict movement of the first insulating material 42 in the lateral direction of the page.

[0034] The first insulating material 42 and the second insulating material 46 suppress temperature changes (keeps beverages cold or hot) stored in the container body 3. The shape of the first insulating material 42 is formed to correspond to the shape of the insulating material storage section (described next) provided in the inner plug upper portion 44. In this embodiment, it is cylindrical. The shape of the second insulating material 46 is formed to correspond to the shape of the insulating material storage section (described later) provided in the inner plug upper portion 47. In this embodiment, it is cylindrical.

[0035] The inside plug upper part 44 has a heat insulating material storage part 44a, a stainless steel ring placement part 44b, a screw-engaging part 44c, and a fitted part 44d. The constituent material of the inside plug upper part 44 is not particularly limited, but examples include resins such as polypropylene. The heat insulating material storage section 44a has a cylindrical shape.

[0036] The stainless steel ring placement portion 44b has a groove provided so as to surround the open end of the upper surface of the heat insulating material storage portion 44a. The stainless steel ring 43 is placed in this stainless steel ring placement portion 44b.

[0037] This inner plug upper part 44 is fixed to the outer lid 41 by a stainless steel ring 43. Specifically, the stainless steel ring 43 is placed in the stainless steel ring placement part 44b, and with the insertion part 41a inserted, heat is generated in the stainless steel ring 43 by electromagnetic induction, melting the resin in the stainless steel ring placement part 44b around the stainless steel ring 43 and welding the inner plug upper part 44 to the insertion part 41a. In addition, by also welding the welding assistant part 41b, the area of ​​the resin to be welded (welded area) can be increased. The space surrounded by the outer lid 41 and the insulation material storage part 44a is an example of a first hollow part. A first insulation material 42 is placed in this space. The threaded portion 44c is disposed on the outer side of the heat insulating material storage portion 44a. The threaded portion 44c is threadedly engaged with the threaded portion 33.

[0038] The fitted portion 44d is disposed below the inside plug upper portion 44 and is formed integrally with the heat insulating material storage portion 44a. The fitted portion 44d is cylindrical with a partial opening on the side. The diameter of this cylinder corresponds to the diameter of the second heat insulating portion 46. A claw portion 441d that protrudes outward is provided at the open end of the fitted portion 44d.

[0039] The inside plug lower part 47 has a heat insulating material storage part 47a, a claw receiving part 47b, a first packing arrangement part 47c, and a second packing arrangement part 47d. The constituent material of the inside plug lower part 47 is not particularly limited, but examples thereof include copolyester resin. The heat insulating material storage portion 47a is cylindrical in shape, and the second heat insulating material 46 is disposed inside the heat insulating material storage portion 47a.

[0040] The claw receiving portion 47b surrounds the open end of the heat insulating material storage portion 47a by projecting inward from the open end. This claw receiving portion 47b fits into the claw portion 441d. The fitted portion 44d is cylindrical with a portion of its side open, which facilitates fitting the claw portion 441d into the claw receiving portion 47b. At this time, the upper portion of the second heat insulating material 46 is surrounded and supported by the fitted portion 44d, and the lower portion of the second heat insulating material 46 is supported by the support portion 471a at the lower portion of the heat insulating material storage portion 47a. The space surrounded by the fitted portion 44d and the heat insulating material storage portion 47a is an example of a second hollow portion. This fitted portion 44d supports a portion of the side of the second heat insulating material 46, thereby restricting movement of the second heat insulating material 46 in the lateral direction of the drawing. In addition, although a gap 47e is formed between the lower part of the second insulating material 46 and the lower part of the insulating material storage portion 47a in FIG. 11, the gap 47e may be omitted.

[0041] The first packing placement portion 47c has a groove provided so as to surround the open end of the upper surface of the heat insulating material storage portion 47a. The first packing placement portion 47c is provided with a packing 45 that prevents liquid from flowing into the heat insulating material storage portion 47a.

[0042] The second packing arrangement portion 47d is arranged in a region surrounding the lower side surface of the inside plug lower portion 47. In this embodiment, a packing 48 that stops the flow of beverage in the reservoir 31 is attached to the second packing arrangement portion 47d so that it cannot be removed.

[0043] The material of the packings 45 and 48 is not particularly limited, but examples thereof include silicone rubber and thermoplastic elastomer.

[0044] When the lid portion 4 is attached to the container body 3, the packing 48 is located on the side of the narrowed portion 34, and stops the beverage in the reservoir portion 31 from entering above the packing 48.

[0045] As described above, the beverage container 10a of the embodiment has a bottomed cylindrical container body 3 having an opening 32, a threaded portion 33 provided inside the opening 32, and a storage portion 31 in which the beverage is stored, an outer lid 41 covering the opening 32, an upper stopper portion 44 that forms a first hollow portion by being joined to the outer lid 41, a lower stopper portion 47 that has a gasket 48 that seals the beverage and that forms a second hollow portion separated from the first hollow portion by being attached to the upper stopper portion 44, a threaded portion 44c provided on the upper stopper portion 44 that threads onto the threaded portion 33, and a first insulating material 42 and a second insulating material 46 that are arranged in the first hollow portion and the second hollow portion, respectively.

[0046] By providing the first insulating material 42 and the second insulating material 46 and dividing the insulating layer into two layers, it is possible to reduce the thermal conductivity from the top of the storage part 31 to the outside of the lid part 4 and to suppress the flow of air, thereby improving the heat retention performance.

[0047] Furthermore, by forming the center plug upper part 44 and the center plug lower part 47 as separate parts rather than being integrally molded, the outer lid 41 and the center plug upper part 44 can be formed from a resin such as polypropylene, and the center plug lower part 47 can be formed from a copolyester resin. This allows for lower costs compared to when the outer lid 41, the center plug upper part 44, and the center plug lower part 47 are all formed from a copolyester resin, or when the center plug upper part 44 and the center plug lower part 47 are all formed from a copolyester resin. In this embodiment, the threaded portion 44c is disposed in the upper portion 44 of the inner plug, but the threaded portion may be disposed in the lower portion 47 of the inner plug. <Third embodiment> Next, a beverage container according to a third embodiment will be described.

[0048] The following description of the beverage container of the third embodiment will focus on the differences from the second embodiment, and will omit a description of similarities. Furthermore, parts having the same functions as the beverage container 10a of the second embodiment will be given the same reference numerals, and detailed descriptions will be omitted.

[0049] Fig. 12 is a side cross-sectional view showing a beverage container according to a third embodiment. Fig. 13 is a development view of a lid according to the third embodiment. Fig. 14 is a cross-sectional view of the development view shown in Fig. 13. Fig. 15 is a side cross-sectional view illustrating a lid according to a second embodiment.

[0050] The beverage container 10b of the second embodiment has a container body 3a and a lid portion 4a. The beverage container 10b differs from the second embodiment mainly in the following three configurations. (1) Screw-fitting structure

[0051] The beverage container 10b of the second embodiment is of a so-called outer lid type, and has a threaded portion 35 that threadably engages with the lid portion 4a on the outer side near the opening 32 of the container body 3a. Also, a threaded portion 41c that threadably engages with the threaded portion 35 is arranged on an outer lid 410 provided on the lid portion 4a. (2) Position of the packing

[0052] The first packing arrangement portion (where the packing 45 is arranged) of the beverage container 10b of the second embodiment is arranged in the upper part of the inside plug, not in the lower part. Specifically, the upper part of the inside plug 440 of the second embodiment is provided with a first packing arrangement portion 44e having a shape corresponding to the packing 45. The outer shape of the upper part of the inside plug 440 and the shape of the corresponding second lower part of the inside plug 470 are slightly different from the upper part of the inside plug 44 and the lower part of the inside plug 47, respectively. However, similar to the second embodiment, the inflow of liquid into the heat insulating material storage portion 47a is suppressed by arranging the packing 45 in the first packing arrangement portion 44e. (3) Shape of the mating part and the claw receiving part

[0053] The fitted portion 440d in the second embodiment is tubular with a partially closed side, whereas the claw receiving portion 470b in the second embodiment is tubular with a partially open side. According to the beverage container 10b of the third embodiment, the same effects as those of the beverage container 10 of the second embodiment can be obtained.

[0054] While the beverage container of the present invention has been described above based on the illustrated embodiment, the present invention is not limited to this, and the configuration of each part can be replaced with any configuration having a similar function. Furthermore, any other components or steps may be added to the present invention. Furthermore, the present invention may be a combination of any two or more configurations (features) of the above-described embodiments. [Explanation of symbols]
