Description

The present invention relates to a container with a lid.

Conventionally, there have been capped containers equipped with a cap unit (stopper) that is removably attached to the neck of a container body that has an open top, thereby closing the top opening of the container body (see, for example, Patent Document 1 below).

Such a cap unit has an outer lid that covers the top opening of the container body, and an inner stopper that fits inside the container body from the top opening, and is structured so that the inner stopper or outer lid is attached to the cap body by screwing.

In addition, some lidded containers, which have a lid that opens and closes the top opening of the container body, also have a cup that can be attached and detached by screwing onto the container body while covering the cap unit.

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.

Note that Figure 1 is a perspective view showing the appearance of lidded container 1A. Figure 2 is a cross-sectional view showing the configuration of lidded container 1A. Figure 3 is a cross-sectional perspective view showing the configuration of the suction portion 23 on the container body 2 side of lidded container 1A. Figure 4 is a cross-sectional perspective view showing the state in which the lid body 3 of lidded container 1A is suctioned to the container body 2. Figure 5 is a cross-sectional perspective view showing suction portions 23A and 23B, which are another example of the suction portion 23. Figure 6 is a perspective view showing another example of the lid body 3.

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

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, which also has an open end, houses the inner container 5, which also has an open end, inside the outer container 4, which also has an open end, 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.

The vacuum insulation layer 6 can be formed, for example, by sealing a vent hole 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.

By having this vacuum insulation structure, the container body 2 can be endowed with the aforementioned heat or cold insulation functions. Furthermore, by having this vacuum insulation structure, the container body 2 is constantly under tension due to the difference between the internal pressure (vacuum pressure) and the external pressure (atmospheric pressure), increasing the mechanical strength of the outer container 4 and 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 inner container 5 are reduced, thereby enabling the container body 2 to be made lighter.

The container body 2 has a substantially circular bottom surface 2b, a body portion 2c that rises in a substantially cylindrical shape from the outer periphery of the bottom surface 2b, and a mouth/neck portion 2d that rises in a substantially cylindrical shape from the upper side of the body portion 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.

A female thread 7 is provided on the inner surface of the neck portion 2d. Furthermore, below the female thread 7, a ring-shaped protrusion 8 is provided, protruding from the inner surface of the inner container 5 around the entire circumference.

The container body 2 also has a structure in which a shoulder member 9 is attached around the entire circumference of the 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 in a generally cylindrical shape overall. The shoulder member 9 is fitted around the entire circumference of the neck portion 2d of the container body 2 so that it is generally flush with the outer periphery of the barrel portion 2c of the container body 2.

Note that, although the lidded container 1A of this embodiment has an overall, generally cylindrical external shape, 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 also be painted, printed, etc.

The lid 3 is removably attached to the neck portion 2d of the container body 2, thereby forming a cap unit (stopper) that closes the upper opening 2a of the container body 2. Specifically, the lid 3 includes a cap body 10 that is attached to the container body 2 by screwing, covering the upper opening 2a of the container body 2.

The cap body 10 has an outer lid 11 that covers the upper opening 2a of the container body 2, and an inner plug 12 that fits inside the container body 2 through the upper opening 2a.

The outer lid 11 is made of, for example, heat-resistant resin, and has a peripheral wall portion 11a formed in a generally cylindrical shape so that its appearance is continuous with the barrel 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.

The inner plug 12 is made of, for example, 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 inner 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 other means. Note that the interior of the inner plug 12 is not limited to being filled with air as an insulating layer, and may instead be configured with insulating material S disposed therein.

Furthermore, 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 this 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 and detached from the container body 2 with a small rotational movement (approximately 180° in this embodiment).

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

The lower end of the inner plug 12 is provided with a reduced diameter portion 12c that is smaller in diameter than the outer diameter of the peripheral wall portion 12b, a ring-shaped flange portion 12d that protrudes in the expanding direction 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.

On the other hand, the inner peripheral surface of the watertight gasket 14 is provided with a ring-shaped mating protrusion 14a that fits into the groove 12e, and a ring-shaped mating recess 14b that fits into the flange 12d. The watertight gasket 14 is removably attached to the outer peripheral portion of the lower end of the inside plug 12 by fitting the mating protrusion 14a into the groove 12e and the flange 12d into the mating recess 14b.

In addition, two elastic flanges 14c are provided on the outer peripheral surface of the watertight gasket 14, protruding in the radial direction. When the cap body 10 (lid body 3) is attached to the container body 2, the elastic flanges 14c of the watertight gasket 14 elastically deform and come into close contact with the protruding portion 8 of the container body 2 around the entire circumference. This makes it possible to seal (stop water) the gap between the protruding portion 8 (container body 2) and the inside plug 12 (cap body 10).

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, keeping the space between the watertight gasket 14 and the cap body 10 hygienic.

The waterproof gasket 14 is not necessarily limited to the shape described above. For example, the number of elastic flange portions 14c is not limited to the two described above, but can be one or more.

Furthermore, the waterproof gasket 14 is not necessarily limited to a configuration with the elastic flange portion 14c described above, and its shape, etc., can be modified as appropriate. For example, the waterproof gasket 14 may be configured with an elastic flange portion that protrudes downward and curves from the upper end of the outer periphery.

The watertight gasket 14 has a bottom projection 15 that projects downward away from a position where it makes contact with the underside of the bottom wall 12a (inner 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 inner plug 12. This creates a gap G around the entire circumference between the inclined surface 15a and the underside of the inner plug 12.

When the lid 3 of the lidded container 1A is removed from the container body 2, the tilt of the lid 3 causes water droplets adhering to the underside of the inner plug 12 to flow along the underside of the inner plug 12 and into the gap G formed between the underside protrusion 15 of the watertight gasket 14. In this case, water droplets collect in the gap G, preventing them from falling off the underside of the inner plug 12.

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 underside protrusion 15 into the inside of the container body 2. This makes it possible to prevent water droplets adhering to the underside of the inner plug 12 from wetting the surrounding area when the lid 3 is removed from the container body 2.

In addition, the gap G formed between the lid body 3 and the underside of the inner plug 12 makes it easy to grasp the underside protrusion 15 of the watertight gasket 14. In this case, by grasping the underside protrusion 15 and elastically deforming (pulling and stretching) the watertight gasket 14, it is possible to easily remove the watertight gasket 14 from the inner plug 12 (cap body 10).

In the lidded container 1A of this embodiment, which has the above-described configuration, the inner stopper 12 is fitted inside the container body 2 through 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 threading the female thread portion 7 into the male thread portion 13.

On the other hand, when the lid body 3 is attached to the container body 2, the outer lid 11 (cap body 10) can be rotated counterclockwise (hereinafter referred to as the "opening direction") relative to the container body 2 to release the female thread portion 7 from the male thread portion 13, allowing the cap body 10 (lid body 3) to be removed from the container body 2.

As shown in Figures 1 to 4, the lidded container 1A of this embodiment is equipped with a lid attraction mechanism 20 that magnetically attracts the lid 3, which has been removed from the container body 2, to the outer periphery of the container body 2.

The lid suction mechanism 20 has a magnet 21 attached to either the container body 2 or the lid body 3 (in this embodiment, the container body 2), and a magnetic body 22 attached to the other (in this embodiment, the lid body 3) that is attracted to the magnet 21.

The magnet 21 is attached to at least a portion of the outer periphery of the container body 2. In this embodiment, an attraction portion 23 is provided on a portion of the shoulder member 9, and the magnet 21 is disposed in this attraction portion 23 while being embedded in the shoulder member 9. The attraction portion 23 is also curved in an arc shape so that the outer periphery is concave, matching the shape of the outer periphery of the lid body 3.

On the other hand, the shoulder member 9 has a base portion 24 that protrudes outward from below the position where the magnet 21 (adsorption portion 23) is located.

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 upper wall portion 11b of the outer lid 11 is attached integrally with the outer lid 11. In other words, the magnetic body 22 is composed of 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 can be integrated with the outer lid 11 by, for example, adhesive bonding or high-frequency welding, or by force-fitting.

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

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 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.

It is possible to achieve the same effect without providing the base 24 by using a high-magnetic-force neodymium magnet as the magnet 21. However, because high-magnetic-force magnets are expensive, providing the base 24 makes it possible to stably attract the cap (magnetic material 22) of the lid body 3 to the attraction portion 23 (magnet 21) even when using a relatively inexpensive low-magnetic-force ferrite magnet.

As a result, with the lidded container 1A of this embodiment, it is possible to prevent the removed lid body 3 from being lost. 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.

As described above, the lidded container 1A of this embodiment is equipped with the above-mentioned lid suction mechanism 20, which allows the lid 3 removed from the container body 2 to be magnetically attracted to the outer periphery of the container body 2, thereby further improving usability.

The lidded container 1A is not necessarily limited to the configuration of the suction section 23 described above; for example, the configuration of the suction section 23A shown in Figure 5(A) or the configuration of the suction section 23B shown in Figure 5(B) is also possible.

Specifically, the attraction portion 23A shown in Figure 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 placed in a storage recess 9a provided in the shoulder member 9 so that a portion of the recess is hollow. This allows the magnet 21 to be hidden from view. Furthermore, the aesthetic appearance can be improved by applying paint or the like to the metal surface of the cover 25A.

On the other hand, the suction part 23B shown in Figure 5 (B) has a configuration in which a magnet 21 and a resin (magnetically permeable) cover 25B that covers the front side of the magnet 21 are placed in a 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.

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).

Specifically, the magnetic body 22A shown in Figure 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 can be integrated with the outer lid 11 by, for example, insert molding or by force-fitting.

This eliminates the need to cover the upper wall portion 11b with the magnetic material 22A. Furthermore, by making the magnetic material 22A ring-shaped, the aesthetic appearance can be improved. Furthermore, by fitting the magnetic material 22A 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.

On the other hand, the magnetic material 22B shown in Figure 6(B) is formed in a chip shape and is configured to be 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 making the magnetic material 22B chip-shaped, the aesthetic appearance can be improved.

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.

Note that Figure 7 is a perspective view showing the state in which the base portion 24A of the container body 2 (shoulder member 9A) of the lidded container 1B is in a position to place the lid body 3. Figure 8 is a perspective view showing the 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. Figure 9 is a side view showing the state in which the strap 27 is attached to the hinge portion 26 on the container body 2 side of the lidded container 1B. Furthermore, in the following explanation, explanations of parts equivalent to those of the lidded container 1A described above will be omitted and the same reference numerals will be used in the drawings.

As shown in Figures 8 and 9, the lidded container 1B of this embodiment is configured with a shoulder member 9A attached to the entire periphery of the container body 2 instead of the shoulder member 9.

Specifically, this shoulder member 9A has a base 24A instead of the base 24 of the shoulder member 9. Like the base 24, the base 24A is made of a resin molded body and has a magnetic body 24a integrated near its center. Furthermore, the base 24A is rotatably attached to the shoulder member 9A via a hinge 26.

This allows the base 24A to rotate freely between a position where the lid 3 is placed and a position facing the attraction portion 23 (magnet 21). Furthermore, the attraction portion 23 (magnet 21) and the magnetic material 24a oppose each other, so the base 24A can be attracted to the attraction portion 23 (magnet 21) by magnetic force. The same effect can be achieved even if the base 24A itself is made of a magnetic metal material.

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

As a result, with the lidded container 1B of this embodiment, it is possible to prevent the removed lid body 3 from being lost. 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.

Furthermore, in the lidded container 1B of this embodiment, as shown in FIG. 8, the base portion 24A can be fixed in place in the folded state by attaching it to the above-mentioned suction portion 23 (magnet 21). This prevents the base portion 24A from getting in the way when not in use, such as when carrying the lidded container 1B.

As described above, the lidded container 1B of this embodiment is equipped with the above-mentioned lid suction mechanism 20, which allows the lid 3 removed from the container body 2 to be magnetically attracted to the outer periphery of the container body 2, thereby further improving usability.

The lidded container 1B of this embodiment can also be configured with a strap 27 attached to the hinge portion 26, as shown in Figure 9, for example. This allows the container to be carried by passing a finger through the strap 27, improving the portability of the lidded container 1B.

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

Note that Figure 10 is a perspective view showing the appearance of the lidded container 1C. Figure 11 is a perspective view showing the state in which the cup 30 of the lidded container 1C is attached to the container body 2. In the following explanation, parts that are equivalent to those in the lidded container 1A will not be described again and will be denoted by the same reference numerals in the drawings.

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

Specifically, this lidded container 1C includes a cap unit 31 that is removably attached to the neck portion 2d of the container body 2 to close the upper opening 2a of the container body 2, and a cup 30 that is removably attached to the container body 2 while covering the cap unit 31.

The cap unit 31 comprises a cap body 32 provided with a liquid passage port (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 opens and closes the liquid passage port when biased in the direction of opening the liquid passage port by a biasing member (not shown) provided on the hinge portion 33; and a lid locking mechanism 35 that secures the opening/closing lid 34 to the cap body against the biasing force of the biasing member when the opening/closing lid 34 is in a position where it closes the liquid passage port.

The cup 30 is made of, for example, 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, giving it an overall cylindrical shape with a bottom.

The cup 30 is detachably attached by threading to the outside of the neck portion 2d of the container body 2 with the bottom wall portion 30a facing upward. Therefore, the inner surface of the peripheral wall portion 30b is provided with a second female thread portion 37 that threads into a second male thread portion 36 provided on the outside of the neck portion 2d of the container body 2.

The cup 30 also has a grip 30c on the side for the user to hold. The grip 30c has a ring shape with both its upper and lower ends connected to the outer periphery of the peripheral wall 30b.

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

The lid suction mechanism 20A has a magnet 21 attached to either the container body 2 or the cup 30 (in this embodiment, the container body), and a magnetic body 38 attached to the other (in this embodiment, the cup 30) that is attracted to the magnet 21.

The magnet 21 has an adhesive portion 23C provided on a part of the shoulder member 9B, and is embedded in the shoulder member 9B at this adhesive portion 23C. The adhesive portion 23C protrudes from the outer periphery of the shoulder member 9B, extends downward, and is curved in an arc so that the outer periphery is concave to match the shape of the outer periphery of the cup 30.

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

The magnetic material 38 is embedded in the side of the cup 30 opposite the side on which the grip 30c is provided.

In the lidded container 1C of this embodiment having the above-described configuration, as shown in FIG. 11, when the cup 30 is removed from the container body 2 and 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.

As a result, with the lidded container 1C of this embodiment, it is possible to prevent the detached cup 30 from being lost. Furthermore, with the lidded container 1C, there is no need to continue holding the detached cup 30 with one hand when pouring the beverage from the container body 2 into a container other than the cup 30.

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.

The lidded container 1C is not necessarily limited to the configuration of the suction portion 23C described above, and it is also possible to adopt the configuration of the suction portion 23A shown in FIG. 5(A) or the configuration of the suction portion 23B shown in FIG. 5(B). It is also possible to adopt the configuration of the pedestal portion 24A instead of the pedestal portion 24B.

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 so 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 so 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.

In this configuration, instead of the female thread portion 7 and male thread portion 13 described above, the outer lid 11 (cap body 10) can be removably attached to the container body 2 by threading a male thread portion provided on the outer peripheral surface of the neck portion 2d with a female thread portion provided on the inner peripheral surface of the peripheral wall portion 11a that constitutes the outer lid 11.

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

Furthermore, for the above-mentioned lidded containers 1A, 1B, and 1C, the shoulder members 9, 9A, and 9B are attached integrally to the container body 2, but they may also be selectively detachable. For example, when used by children who tend to drop the lid 3, shoulder members 9, 9A, and 9B can be used, and when used by adults, the base 24, 24A, and 24B can be omitted and replaced with shoulder members that are easier to carry.

In the above embodiment, the present invention is illustrated as being applied to a beverage container that has a heat-retaining (or cold-retaining) function provided by the container body 2 having the vacuum insulation structure described above. However, the present invention can be widely applied to a lidded container that includes a container body and a lid that can be detachably attached to the container body.
