[0011] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. (First embodiment) First, as a first embodiment of the present invention, a container with lid 1A shown in, for example, FIGS. 1 to 6 will be described.

[0012] FIG. 1 is a perspective view showing the appearance of lidded container 1A. FIG. 2 is a cross-sectional view showing the configuration of lidded container 1A. FIG. 3 is a cross-sectional perspective view showing the configuration of suction section 23 on the container body 2 side of lidded container 1A. FIG. 4 is a cross-sectional perspective view showing the state in which lid body 3 of lidded container 1A is suctioned to container body 2. FIG. 5 is a cross-sectional perspective view showing suction sections 23A and 23B, which are another example of the configuration of suction section 23. FIG. 6 is a perspective view showing another example of the configuration of lid body 3.

[0013] As shown in Figures 1 and 2, the lidded container 1A of this embodiment is a beverage container that comprises a container body 2 that is open at the top and a lid body 3 that can be attached and detached freely to the container body 2, and is capable of keeping the beverage (contents) contained in the container body 2 hot or cold.

[0014] Specifically, the container body 2 has an outer container 4 and an inner container 5 made of metal such as stainless steel. The container body 2 has a vacuum insulation structure in which the outer container 4 has one open end and the inner container 5 has one open end housed inside the outer container 4, with the open ends of the two containers joined together, and a vacuum insulation layer 6 is provided between the outer container 4 and the inner container 5.

[0015] The vacuum insulation layer 6 can be formed, for example, by sealing an air vent hole provided in the center of the bottom surface of the outer container 4 with brazing material in a chamber that has been depressurized (evacuated) to a high vacuum.

[0016] The container body 2 has such a vacuum insulation structure, which allows it to have the above-mentioned functions of keeping things warm or cold. Furthermore, the container body 2 has such a vacuum insulation structure, which causes tension to be constantly applied to the outer container 4 and the inner container 5 due to the difference between the internal pressure (vacuum pressure) and the external pressure (atmospheric pressure), thereby increasing the mechanical strength of the outer container 4 and the inner container 5. This makes it possible to increase the rigidity of the container body 2 even when the plate thicknesses of the outer container 4 and the inner container 5 are reduced, and thus makes it possible to reduce the weight of the container body 2.

[0017] The container body 2 has a substantially circular bottom surface 2b, a body 2c that stands in a substantially cylindrical shape from the outer periphery of the bottom surface 2b, and a mouth / neck portion 2d that stands in a substantially cylindrical shape from the upper side of the body 2c. The upper end of the mouth / neck portion 2d opens in a circular shape as the upper opening 2a of the container body 2.

[0018] The inner circumferential surface of the mouth / neck portion 2d is provided with a female thread portion 7. Furthermore, below the female thread portion 7, a ring-shaped protruding portion 8 is provided so as to protrude from the inner circumferential surface of the inner container 5 around the entire circumference.

[0019] The container body 2 has a structure in which a shoulder member 9 is attached around the entire circumference of the mouth / neck portion 2d (the outer periphery of the upper side of the container body 2). The shoulder member 9 is made of, for example, a resin molded body, and is formed into a substantially cylindrical shape as a whole. The shoulder member 9 is fitted around the entire circumference of the mouth / neck portion 2d of the container body 2 so as to be substantially flush with the outer periphery of the barrel portion 2c of the container body 2.

[0020] Although the lidded container 1A of this embodiment has a generally cylindrical external shape overall, the external shape of the lidded container 1A is not particularly limited and can be modified as appropriate to suit the size, design, etc. The outer peripheral surface of the container body 2 (outer container 4) may be painted, printed, or the like.

[0021] The lid body 3 is detachably attached to the mouth / neck portion 2d of the container body 2 to form a cap unit (stopper body) that closes the upper opening 2a of the container body 2. Specifically, the lid body 3 includes a cap body 10 that is attached to the container body 2 by screwing, while covering the upper opening 2a of the container body 2.

[0022] The cap body 10 has an outer lid 11 that covers the upper opening 2a of the container body 2, and an inside plug 12 that is fitted into the inside of the container body 2 through the upper opening 2a.

[0023] The outer lid 11 is made of, for example, a heat-resistant resin, and has a peripheral wall portion 11a that is formed in an approximately cylindrical shape so that its appearance is continuous with the body portion 2c and shoulder member 9 of the container body 2, and an upper wall portion 11b that closes the upper part of the peripheral wall portion 11a.

[0024] The inside plug 12 is made of, for example, a heat-resistant resin and has a substantially circular bottom wall 12a and a substantially cylindrical peripheral wall 12b rising from the periphery of the bottom wall 12a. The inside plug 12 is located in the center of the inside of the outer lid 11, and the peripheral wall 12b is attached integrally to the center of the underside of the upper wall 11b by welding or the like. Note that the inside of the inside plug 12 is not limited to being filled with air as an insulating layer, and a thermal insulating material S may also be disposed therein.

[0025] Additionally, a male thread portion 13 is provided on the outer peripheral surface of the peripheral wall portion 12b (inner plug 12). In the lidded container 1A, the cap body 10 (lid body 3) is detachably attached to the container body 2 by threading the male thread portion 13 into the female thread portion 7. Furthermore, the female thread portion 7 and the male thread portion 13 are double-threaded threads that are complementary to each other. When a double-threaded thread is used, the cap body 10 (lid body 3) can be attached to and detached from the container body 2 with a small rotational operation (approximately 180° in this embodiment).

[0026] A waterproof gasket 14 is detachably attached to the outer periphery of the lower end of the inside plug 12. The waterproof gasket 14 is a ring-shaped sealing member that seals the gap between the protruding portion 8 of the container body 2 and the inside plug 12, and is made of a heat-resistant elastic material such as silicone rubber.

[0027] The lower end of the inside plug 12 is provided with a reduced diameter portion 12c having a diameter smaller than the outer diameter of the peripheral wall portion 12b, a ring-shaped flange portion 12d protruding in the direction of increasing diameter from the lower end of the reduced diameter portion 12c around the entire circumference, and a ring-shaped groove portion 12e between the reduced diameter portion 12c and the flange portion 12d.

[0028] Meanwhile, a ring-shaped fitting protrusion 14a that fits into groove 12e and a ring-shaped fitting recess 14b that fits into flange 12d are provided on the inner peripheral surface of watertight gasket 14. Watertight gasket 14 is detachably attached to the outer periphery of the lower end side of inside plug 12 by fitting fitting protrusion 14a into groove 12e and fitting flange 12d into fitting recess 14b.

[0029] Additionally, two elastic flange portions 14c are provided on the outer peripheral surface of the watertight gasket 14, protruding in the radially expanding direction. When the cap body 10 (lid body 3) is attached to the container body 2, the elastic flange portions 14c of the watertight gasket 14 elastically deform and come into close contact with the protruding portion 8 of the container body 2 over the entire circumference. This makes it possible to seal (watertightly seal) the gap between the protruding portion 8 (container body 2) and the inside plug 12 (cap body 10).

[0030] On the other hand, the watertight gasket 14 can be removed from the inside plug 12 (cap body 10) by elastically deforming (pulling and stretching) itself. This allows the cap body 10 and the watertight gasket 14 to be washed separately, and the space between the watertight gasket 14 and the cap body 10 can be kept hygienic.

[0031] It should be noted that the waterproof gasket 14 is not necessarily limited to the shape described above, and for example, the number of elastic flange portions 14c is not limited to the two described above, but can be one or more.

[0032] Furthermore, the waterproof gasket 14 is not necessarily limited to a configuration in which the elastic flange portion 14c is provided as described above, and its shape, etc., can be appropriately modified. For example, the waterproof gasket 14 may be configured to have an elastic flange portion that protrudes downward while curving from the upper end of the outer circumferential surface thereof.

[0033] The watertight gasket 14 has a bottom projection 15 that projects in a direction (downward) away from a position where it contacts the underside of the bottom wall 12a (inside plug 12) around the entire circumference. The bottom projection 15 has an inclined surface 15a on its inner periphery that forms an acute angle with the underside of the inside plug 12. As a result, a gap G is provided around the entire circumference between the inclined surface 15a and the underside of the inside plug 12.

[0034] In the case of the lidded container 1A, when the lid 3 is removed from the container body 2, the tilt of the lid 3 causes water droplets adhering to the underside of the inside plug 12 to flow along the underside of the inside plug 12 into the gap G formed between the inside plug 12 and the underside protrusion 15 of the watertight gasket 14. In this case, the water droplets collect in the gap G, making it possible to prevent the water droplets adhering to the underside of the inside plug 12 from falling.

[0035] On the other hand, when the lid 3 is reattached to the container body 2, water droplets that have flowed into the gap G can be made to fall along the inclined surface 15a of the lower surface protrusion 15 into the inside of the container body 2. This makes it possible to prevent water droplets adhering to the lower surface of the inside plug 12 from wetting the surrounding area when the lid 3 is removed from the container body 2.

[0036] Furthermore, in the lid body 3, the lower surface protrusion 15 of the watertight gasket 14 can be easily grasped due to the gap G formed between the lid body 3 and the underside of the inside plug 12. In this case, by grasping the lower surface protrusion 15 and elastically deforming (pulling and stretching) the watertight gasket 14, the watertight gasket 14 can be easily removed from the inside plug 12 (cap body 10).

[0037] In the lidded container 1A of this embodiment having the above-described configuration, the inner stopper 12 is fitted inside the container body 2 from the upper opening 2a, and then the outer lid 11 (cap body 10) can be rotated clockwise (hereinafter referred to as the "closing direction") relative to the container body 2, thereby attaching the cap body 10 (lid body 3) to the container body 2 by screwing the female screw portion 7 and the male screw portion 13 together.

[0038] On the other hand, when the lid body 3 is attached to the container body 2, by rotating the outer lid 11 (cap body 10) counterclockwise (hereinafter referred to as the "opening direction") relative to the container body 2, the female thread portion 7 and the male thread portion 13 can be released from the screw engagement, and the cap body 10 (lid body 3) can be removed from the container body 2.

[0039] Incidentally, the lidded container 1A of this embodiment is provided with a lid attracting mechanism 20 that magnetically attracts the lid body 3 removed from the container body 2 to the outer periphery of the container body 2, as shown in FIGS.

[0040] The lid adsorption mechanism 20 has a magnet 21 provided on either the container body 2 or the lid body 3 (in this embodiment, the container body 2), and a magnetic body 22 provided on the other (in this embodiment, the lid body 3) and adsorbed to the magnet 21.

[0041] The magnet 21 is attached to at least a part of the outer periphery of the container body 2. In this embodiment, an attraction portion 23 is provided on a part of the shoulder member 9, and the magnet 21 is disposed in this attraction portion 23 in a state where it is embedded in the shoulder member 9. The attraction portion 23 is curved in an arc shape so that the outer periphery side is concave to match the shape of the outer periphery of the lid body 3.

[0042] On the other hand, the shoulder member 9 has a base portion 24 that protrudes outward from below the position where the magnet 21 (attraction portion 23) is arranged.

[0043] The magnetic body 22 is attached to at least a portion of the outer periphery of the lid body 3. In this embodiment, the cap-shaped magnetic body 22 that covers the peripheral wall portion 11a and the upper wall portion 11b of the outer lid 11 is attached integrally with the outer lid 11. That is, the magnetic body 22 is configured as a metal cap that covers the entire periphery of the peripheral wall portion 11a and the entire upper wall portion 11b of the outer lid 11. The magnetic body 22 may be integrated with the outer lid 11 by, for example, adhesive bonding or high-frequency welding, or may be fitted by force.

[0044] In the lidded container 1A of this embodiment having the above-described configuration, as shown in Figure 4, the lid body 3 removed from the container body 2 can be placed upside down on the base portion 24, and the cap (magnetic material 22) of the lid body 3 can be attracted to the attraction portion 23 (magnet 21) provided on the outer periphery of the container body 2.

[0045] In addition, in the lidded container 1A of this embodiment, the magnetic material 22 covers the entire periphery of the peripheral wall portion 11a of the outer lid 11, so that the cap (magnetic material 22) of the lid body 3 can be attracted to the attraction portion 23 (magnet 21) without having to worry about the orientation of the lid body 3.

[0046] It should be noted that by using a high magnetic force neodymium magnet or the like as magnet 21, it is possible to obtain the same effect without providing base 24. However, since high magnetic force magnets are expensive, providing base 24 makes it possible to stably attract the cap (magnetic body 22) of lid body 3 to attraction portion 23 (magnet 21) even when using a relatively inexpensive low magnetic force ferrite magnet or the like.

[0047] This makes it possible to prevent the lidded container 1A of this embodiment from losing the removed lid body 3. Furthermore, with the lidded container 1A, there is no need to continue holding the removed lid body 3 with one hand when pouring the beverage from the container body 2.

[0048] As described above, in the lidded container 1A of this embodiment, by being equipped with the above-mentioned lid suction mechanism 20, the lid body 3 removed from the container body 2 can be magnetically attracted to the outer periphery of the container body 2, thereby further improving usability.

[0049] In addition, the above-mentioned lidded container 1A is not necessarily limited to the configuration of the adsorption section 23 described above, and it is also possible to use, for example, the configuration of the adsorption section 23A shown in Figure 5(A) or the configuration of the adsorption section 23B shown in Figure 5(B).

[0050] Specifically, the attraction portion 23A shown in Fig. 5(A) has a configuration in which a magnet 21 and a metallic (magnetically permeable) cover 25A that covers the front side of the magnet 21 are disposed in a storage recess 9a that is provided in the shoulder member 9 so as to be partially hollow. This allows the magnet 21 to be hidden from the outside. In addition, the aesthetic appearance can be improved by applying paint or the like to the metal surface of the cover 25A.

[0051] On the other hand, the attraction part 23B shown in Fig. 5(B) has a configuration in which the magnet 21 and a resin (magnetically permeable) cover 25B that covers the front side of the magnet 21 are arranged in the storage recess 9a provided in the shoulder member 9. This allows the magnet 21 to be hidden from the outside. In addition, the aesthetic appearance can be improved by selecting the resin color of the cover 25B.

[0052] Furthermore, the above-mentioned lidded container 1A is not necessarily limited to the configuration of the cap-shaped magnetic body 22 described above, and it is also possible to use, for example, the configuration of the magnetic body 22A shown in Figure 6(A) or the configuration of the magnetic body 22B shown in Figure 6(B).

[0053] 6(A) is formed in a ring shape and fitted around the entire periphery of the peripheral wall portion 11a of the outer lid 11. The magnetic body 22A may be integrated with the outer lid 11 by, for example, insert molding or forced fitting.

[0054] This eliminates the need to cover the upper wall portion 11b with the magnetic material 22A. Also, by making the magnetic material 22A ring-shaped, the aesthetic appearance can be improved. Furthermore, since the magnetic material 22A is fitted around the entire periphery of the peripheral wall portion 11a of the outer lid 11, the cap (magnetic material 22A) of the lid body 3 can be attracted to the attraction portion 23 (magnet 21) without having to worry about the orientation of the lid body 3.

[0055] 6(B) is configured to be formed in a chip shape and embedded in the peripheral wall portion 11a of the outer lid 11 by, for example, insert molding. This eliminates the need to cover the upper wall portion 11b with the magnetic material 22B. Furthermore, by forming the magnetic material 22B in a chip shape, the aesthetic appearance can be improved.

[0056] (Second embodiment) Next, a lidded container 1B shown in, for example, FIGS. 7 to 9 will be described as a second embodiment of the present invention.

[0057] 7 is a perspective view showing a state in which the base portion 24A of the container body 2 (shoulder member 9A) of the lidded container 1B is in a position where the lid body 3 is placed. FIG. 8 is a perspective view showing a state in which the base portion 24A of the container body 2 (shoulder member 9A) of the lidded container 1B is in a position facing the suction portion 23. FIG. 9 is a side view showing a state in which a strap 27 is attached to the hinge portion 26 on the container body 2 side of the lidded container 1B. In the following explanation, explanations of parts equivalent to those of the lidded container 1A will be omitted and the same reference numerals will be used in the drawings.

[0058] As shown in FIGS. 8 and 9, the lidded container 1B of this embodiment is configured to have a shoulder member 9A attached to the container body 2 around the entire periphery, instead of the shoulder member 9.

[0059] Specifically, this shoulder member 9A has a pedestal portion 24A instead of the pedestal portion 24 of the shoulder member 9. The pedestal portion 24A is made of a resin molded body like the pedestal portion 24, and has a magnetic body 24a integrated near the center. In addition, the pedestal portion 24A is rotatably attached to the shoulder member 9A via a hinge portion 26.

[0060] This allows base 24A to rotate freely between a position where lid 3 is placed and a position facing attracting portion 23 (magnet 21). Furthermore, attracting portion 23 (magnet 21) and magnetic body 24a oppose each other, so that base 24A can be attracted to attracting portion 23 (magnet 21) by magnetic force. Note that the same effect can be obtained even if base 24A itself is a magnetic body made of metal.

[0061] In the lidded container 1B of this embodiment having the above-described configuration, when the lid body 3 removed from the container body 2 is placed on the base portion 24A, the cap (magnetic body 22) of the lid body 3 can be attracted to the attraction portion 23 (magnet 21) provided on the outer periphery of the container body 2.

[0062] This makes it possible to prevent the lidded container 1B of this embodiment from losing the removed lid body 3. Furthermore, with the lidded container 1B, there is no need to continue holding the removed lid body 3B with one hand when pouring the beverage from the container body 2.

[0063] 8, in the lidded container 1B of this embodiment, the pedestal portion 24A can be fixed in place in the folded state by attracting the pedestal portion 24A to the above-mentioned attraction portion 23 (magnet 21). This prevents the pedestal portion 24A from getting in the way when not in use, such as when carrying the lidded container 1B.

[0064] As described above, in the lidded container 1B of this embodiment, by being equipped with the above-mentioned lid suction mechanism 20, the lid body 3 removed from the container body 2 can be magnetically attracted to the outer periphery of the container body 2, thereby further improving usability.

[0065] 9, the lidded container 1B of this embodiment can also be configured with a strap 27 attached to the hinge portion 26. This allows the lidded container 1B to be carried by passing a finger through the strap 27, thereby improving the portability of the lidded container 1B.

[0066] (Third embodiment) Next, a lidded container 1C shown in Figs. 10 and 11 will be described as a third embodiment of the present invention.

[0067] Fig. 10 is a perspective view showing the appearance of container with lid 1C. Fig. 11 is a perspective view showing the state in which cup 30 of container with lid 1C is attached to container body 2. In the following explanation, the same parts as those in container with lid 1A will not be described and will be denoted by the same reference numerals in the drawings.

[0068] As shown in Figures 10 and 11, the lidded container 1C of this embodiment is configured to have a cup 30, which is a form of lid that can be removably attached to the container body 2, instead of the lid 3.

[0069] Specifically, this lidded container 1C includes a cap unit 31 that closes the upper opening 2a of the container body 2 by being removably attached to the neck portion 2d of the container body 2, and a cup 30 that can be removably attached to the container body 2 while covering the cap unit 31.

[0070] The cap unit 31 includes a cap body 32 provided with a liquid passage (not shown) that communicates with the inside of the container body 2, an opening / closing lid 34 that is rotatably attached to the cap body 32 via a hinge portion 33 and that opens and closes the liquid passage when biased in the direction of opening the liquid passage by a biasing member (not shown) provided on the hinge portion 33, and a lid locking mechanism 35 that fixes the opening / closing lid 34 to the cap body against the bias of the biasing member when the opening / closing lid 34 is in a position where it blocks the liquid passage.

[0071] The cup 30 is made of, for example, a heat-resistant resin, and has a substantially circular bottom wall portion 30a and a cylindrical peripheral wall portion 30b that rises upward from the periphery of the bottom wall portion 30a, and is formed into a cylindrical shape with a bottom as a whole.

[0072] The cup 30, with the bottom wall 30a facing upward, is detachably attached by screwing to the outside of the mouth / neck portion 2d of the container body 2. For this reason, the inner circumferential surface of the peripheral wall 30b is provided with a second female screw portion 37 that screws into a second male screw portion 36 provided on the outside of the mouth / neck portion 2d of the container body 2.

[0073] A grip portion 30c to be gripped by a user is provided on the side of the cup 30. The grip portion 30c has a ring shape with both upper and lower ends connected to the outer circumferential surface of the peripheral wall portion 30b.

[0074] The lidded container 1C of this embodiment is provided with a lid attracting mechanism 20A that magnetically attracts the cup 30 removed from the container body 2 to the outer periphery of the container body 2.

[0075] The lid adsorption mechanism 20A has a magnet 21 provided on either the container body 2 or the cup 30 (the container body in this embodiment), and a magnetic body 38 provided on the other (the cup 30 in this embodiment) and adsorbed to the magnet 21.

[0076] Magnet 21 has an attraction portion 23C provided on a part of shoulder member 9B, and magnet 21 is disposed in a state where it is embedded in shoulder member 9B at attraction portion 23C. Furthermore, attraction portion 23C protrudes from the outer peripheral surface of shoulder member 9B, extends downward, and is curved in an arc shape so that the outer periphery is concave to match the shape of the outer periphery of cup 30.

[0077] On the other hand, the shoulder member 9B has a base portion 24B that protrudes outward from below the position where the magnet 21 (attraction portion 23C) is disposed.

[0078] The magnetic body 38 is embedded in the side surface of the cup 30 opposite to the side on which the grip portion 30c is provided.

[0079] In the lidded container 1C of this embodiment having the above-described configuration, as shown in Figure 11, when the cup 30 removed from the container body 2 is placed on the base portion 24B, the cup 30 (magnetic material 38) can be attracted to the attraction portion 23C (magnet 21) provided on the outer periphery of the container body 2.

[0080] This makes it possible to prevent the detached cup 30 from being lost in the lidded container 1C of this embodiment. Furthermore, when pouring the beverage in the container body 2 into a container other than the cup 30, the detached cup 30 does not need to be held in one hand.

[0081] As described above, the lidded container 1C of this embodiment is equipped with the above-mentioned lid suction mechanism 20A, which allows the cup 30 removed from the container body 2 to be magnetically attracted to the outer periphery of the container body 2, thereby further improving usability.

[0082] The lidded container 1C is not necessarily limited to the configuration of the suction part 23C described above, and may employ the configuration of the suction part 23A shown in Fig. 5(A) or the configuration of the suction part 23B shown in Fig. 5(B). Also, the configuration of the pedestal part 24A may be employed instead of the pedestal part 24B.

[0083] The present invention is not necessarily limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, the lid 3 is configured such that the inner plug 12 is attached to the container body 2 by screwing while the lid 3 is fitted inside from the upper opening 2a of the container body 2, but the configuration is not necessarily limited to this. For example, the lid 3 may be configured such that the outer lid 11 is attached to the container body 2 by screwing while the lid 3 covers the upper opening 2a of the container body 2 from the outside.

[0084] In this configuration, instead of the above-mentioned female screw portion 7 and male screw portion 13, the outer lid 11 (cap body 10) can be attached and detached freely to the container body 2 by screwing together a male screw portion provided on the outer peripheral surface of the neck portion 2d and a female screw portion provided on the inner peripheral surface of the peripheral wall portion 11a that constitutes the outer lid 11.

[0085] Furthermore, the above-mentioned lidded containers 1A, 1B are configured to directly open and close the upper opening 2a of the container body 2, but are not necessarily limited to this configuration. For example, it is also possible to configure the lid body 3 to be detachably attached to shoulder members 9, 9A attached to the container body 2.

[0086] Furthermore, although the above-mentioned shoulder members 9, 9A, 9B of the lidded containers 1A, 1B, 1C are configured to be attached integrally to the container body 2, they may also be configured to be selectively detachable. For example, when used by a child who often drops the lid 3, the shoulder members 9, 9A, 9B can be used, and when used by an adult, the base portions 24, 24A, 24B can be omitted and replaced with shoulder members that are easier to carry.

[0087] In the above embodiment, the present invention is exemplified as being applied to a beverage container having a heat-retaining (or cold-retaining) function provided by a container body 2 having the above-mentioned vacuum insulation structure, but the present invention can be widely applied to a lidded container having a container body and a lid that can be attached and detached to the container body.
