Patent document 1: japanese laid-open patent publication No. 2010-280402
However, in the above-described container with a lid, for example, when a hot beverage is poured into the container main body, water vapor saturated in the container main body condenses on the lower surface of the inner plug, and becomes water droplets to adhere to the lower surface of the inner plug. Water droplets attached to the lower surface of the inner plug gradually grow and drop into the container body due to their own weight.
On the other hand, there are cases where: when the lid unit is removed from the container body, water droplets adhering to the lower surface of the inside plug flow down from the inclined lid unit, thereby wetting the surroundings. If the water droplets adhering to the lower surface of the inner plug can be quickly dropped toward the inside of the container main body, it is possible to suppress the periphery from being wetted by the water droplets adhering to the lower surface of the inner plug when the lid unit is removed from the container main body. However, water droplets adhering to the lower surface of the inner plug are difficult to fall down due to surface tension acting between the water droplets and the lower surface of the inner plug.

Detailed Description
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
(embodiment 1)
First, as embodiment 1 of the present invention, a lidded container 100A provided with a lid unit 1A shown in fig. 1, for example, will be described.
The present embodiment is a cross-sectional view showing the structure of a lidded container 100A provided with a lid unit 1A.
As shown in fig. 1, the lidded container 100A of the present embodiment is a beverage container as follows: the container includes a container body 2 having an upper opening, and a lid unit 1A detachably attached to the container body 2, and is capable of keeping warm a hot beverage (contents) stored in the container body 2. In addition, in the lidded container 100A, the upper opening 2a of the container main body 2 can be opened and closed by the lid unit 1A attached to the container main body 2 by screwing.
Specifically, the container body 2 includes an outer container 3 and an inner container 4 made of metal such as stainless steel. The container body 2 has the following vacuum insulation structure: in a state where the inner container 4 having one open end is housed inside the outer container 3 having one open end, the open ends thereof are joined to each other, and a vacuum insulation layer 5 is provided between these outer container 3 and inner container 4.
The vacuum insulation layer 5 can be formed by sealing a degassing hole provided in the center of the bottom surface of the outer container 3 with solder in a chamber that is depressurized (evacuated) to a high vacuum, for example.
Since the container body 2 has such a vacuum heat insulating structure, it can be provided with the above-described heat insulating or cold insulating function. Further, since the container main body 2 has such a vacuum heat insulation structure, tension is constantly applied to the outer container 3 and the inner container 4 by a difference between an internal pressure (vacuum pressure) and an external pressure (atmospheric pressure), and mechanical strength of the outer container 3 and the inner container 4 is increased. Thus, even when the thicknesses of the outer container 3 and the inner container 4 are reduced, the rigidity of the container main body 2 can be increased, and the container main body 2 can be made lighter.
The container body 2 has: a substantially circular bottom surface portion 2b; a body portion 2c rising in a substantially cylindrical shape from the outer periphery of the bottom surface portion 2b; and a mouth-and-neck portion 2d rising in a substantially cylindrical shape from the upper side of the body portion 2c. The upper end of the mouth-and-neck portion 2d is opened in a circular shape as an upper opening portion 2a of the container body 2.
A female screw portion 6 is provided on the inner peripheral surface of the mouth-and-neck portion 2 d. An annular projecting portion 7 projects from the inner peripheral surface of the inner container 4 over the entire periphery thereof below the internal screw portion 6.
The entire capped container 100A of the present embodiment has a substantially cylindrical external shape, but the external shape of the capped container 100A is not particularly limited, and may be appropriately changed according to the size, the external design, and the like. Further, coating, printing, or the like may be applied to the outer peripheral surface of the container main body 2 (outer container 3).
The lid unit 1A of the present embodiment constitutes a plug body that closes the upper opening 2a of the container main body 2. Specifically, the lid unit 1A includes a lid main body 8, and the lid main body 8 is attached to the container main body 2 by screwing in a state of covering the upper opening 2a of the container main body 2.
The cap main body 8 has: an outer lid 9 covering the upper opening 2a of the container body 2; and an inner plug 10 fitted into the container body 2 from the upper opening 2 a.
The outer cover 9 is made of a heat-resistant resin such as polypropylene, tritan (registered trademark), and has: a peripheral wall portion 9a formed in a substantially cylindrical shape so as to be continuous in appearance with the body portion 2c of the container body 2; and an upper wall portion 9b that closes an upper portion of the peripheral wall portion 9a.
The inside plug 10 is made of a heat-resistant resin such as polypropylene or Tritan (registered trademark), and has: a substantially circular bottom wall portion 10a; and a peripheral wall portion 10b rising in a substantially cylindrical shape from the periphery of the bottom wall portion 10 a. The inside plug 10 is located at the inner center portion of the outer lid 9, and the peripheral wall portion 10b is integrally attached to the lower center portion of the upper wall portion 9b by welding or the like. The inside of the inside plug 10 may be configured to have a heat insulating material (not shown) disposed therein, and is not limited to air serving as a heat insulating layer.
Further, a male screw portion 11 is provided on the outer peripheral surface of the peripheral wall portion 10b (the inside plug 10). In the capped container 100A, the internal plug 10 (cap body 8) is detachably attached to the container body 2 by screwing the external thread portion 11 and the internal thread portion 6. The female screw portion 6 and the male screw portion 11 are formed of double threads that are complementary to each other. In the case of using the double thread, the cap body 8 (cap unit 1A) can be attached to and detached from the container body 2 with a small number of rotational operations (about 180 ° in the present embodiment).
A water seal packing 12 is detachably attached to the outer periphery of the lower end side of the inside plug 10. The water seal packing 12 is an annular seal member for sealing a space between the inside of the container body 2 and the inside plug 10, and is made of, for example, a heat-resistant rubber such as silicone rubber, or an elastic member such as an elastomer.
The lower end side of the inside plug 10 is provided with: a reduced diameter portion 10c having a diameter reduced from the outer diameter of the peripheral wall portion 10 b; an annular flange portion 10d that protrudes from the lower end of the reduced diameter portion 10c over the entire circumference in the diameter expansion direction; and an annular groove portion 10e located between the reduced diameter portion 10c and the flange portion 10 d.
On the other hand, the inner peripheral surface of the water stop packing 12 is provided with: an annular fitting protrusion 12a fitted to the groove 10e; and an annular fitting recess 12b into which the flange 10d is fitted. The water seal packing 12 is detachably attached to the outer periphery of the lower end side of the inside plug 10 by fitting the fitting convex portion 12a to the groove portion 10e and fitting the flange portion 10d to the fitting concave portion 12 b.
Further, 2 elastic flange portions 12c are provided on the outer peripheral surface of the water stop packing 12 so as to protrude in the diameter expansion direction. The water stop packing 12 is in the following state: when the cap body 8 is attached to the container body 2, the elastic flange portion 12c elastically deforms and comes into close contact with the extension portion 7 of the container body 2 over the entire circumference. This makes it possible to seal (stop) the space between the protruding portion 7 (container body 2) and the inside plug 10 (cap body 8).
On the other hand, the water stop packing 12 can be removed from the inside plug 10 (the cap body 8) by elastically deforming (extending and elongating) itself. Thereby, the cover main body 8 and the water stop packing 12 can be cleaned separately, and the sanitation between the water stop packing 12 and the cover main body 8 can be maintained.
The water seal gasket 12 is not necessarily limited to the above shape, and for example, the number of the elastic flange portions 12c is not limited to the above 2, and may be formed into 1 or more.
The water seal gasket 12 is not necessarily limited to the configuration in which the elastic flange portion 12c is provided, and the shape thereof may be appropriately changed. For example, the following may be configured: an elastic flange portion having a shape that is bent downward from the upper end of the outer peripheral surface of the water stop pad 12 and protrudes is provided.
The water stop packing 12 has a lower surface side protruding portion 13, and the lower surface side protruding portion 13 protrudes in a direction of separation (downward) from a position in contact with the lower surface of the bottom wall portion 10a (inside plug 10) over the entire circumference. The lower surface side protrusion 13 has an inclined surface 13a that forms an acute angle with respect to the lower surface of the inside plug 10 on the inner peripheral side thereof. Thereby, a gap S is provided between the inclined surface 13a and the lower surface of the inside plug 10 over the entire circumference.
In the lidded container 100A of the present embodiment having the above-described configuration, the outer lid 9 (lid body 8) is rotated clockwise (hereinafter referred to as "closing direction") with respect to the container body 2 from the state in which the plug 10 is fitted from the upper opening 2a to the inside of the container body 2, and the lid unit 1A can be attached to the container body 2 by screwing the female screw portion 6 and the male screw portion 11.
On the other hand, in a state where the cap body 8 (cap unit 1A) is attached to the container body 2, the outer cap 9 (cap body 8) is rotated to the left (hereinafter referred to as "opening direction") with respect to the container body 2, and the female screw portion 6 and the male screw portion 11 are disengaged from each other, so that the cap unit 1A can be removed from the container body 2.
However, in the lidded container 100A of the present embodiment, in a state in which the lid unit 1A is attached to the container main body 2, water vapor saturated in the container main body 2 condenses on the lower surface of the inside plug 10, and becomes water droplets (not shown) and adheres to the lower surface of the inside plug 10. In addition, water droplets adhering to the lower surface of the inside plug 10 are difficult to fall down due to surface tension acting between the water droplets and the lower surface of the inside plug 10.
On the other hand, when the lid unit 1A is removed from the container body 2, water droplets adhering to the lower surface of the inside plug 10 flow into the gap S formed between the lower surface side protruding portion 13 of the water stop packing 12 along the lower surface of the inside plug 10 due to the inclination of the lid unit 1A. In this case, water droplets are accumulated in the gap S, and the water droplets adhering to the lower surface of the inside plug 10 can be suppressed from falling.
On the other hand, when the cover unit 1A is attached to the container body 2 again, the water droplets flowing into the gap S can be made to fall down to the inside of the container body 2 along the inclined surface 13a of the lower surface side protrusion 13.
Thus, in the lidded container 100A of the present embodiment, when the lid unit 1A is removed from the container body 2, it is possible to suppress the periphery from being wetted by water droplets adhering to the lower surface of the inside plug 10.
In the capped container 100A of the present embodiment, the lower surface side protrusion 13 of the water seal packing 12 is easily caught by the gap S formed between the lower surface of the inside plug 10 and the lower surface side protrusion. In this case, the water stop packing 12 can be easily removed from the inside plug 10 (the cap body 8) by grasping the lower surface side protruding portion 13 and elastically deforming (stretching and expanding) the water stop packing 12.
In order to facilitate grasping of the lower surface side protrusion 13, it is preferable to provide at least a gap S equal to or larger than the thickness of the lower surface side protrusion 13 (water stop pad 12). In order to facilitate accumulation of water droplets in the gap S, the angle of the inclined surface 13a of the lower surface side protrusion 13 is preferably in the range of 10 to 80 °.
As described above, the lidded container 100A of the present embodiment includes the lid unit 1A described above, and therefore can achieve further improvement in usability.
(embodiment 2)
Next, as embodiment 2 of the present invention, a lidded container 100B provided with a lid unit 1B shown in fig. 2, for example, will be described.
Fig. 2 is a cross-sectional view showing the structure of a lidded container 100B provided with a lid unit 1B. In the following description, the same parts as those of the lidded container 100A provided with the lid unit 1A are not described, and the same reference numerals are given to the drawings.
As shown in fig. 2, the container with a lid 100B of the present embodiment has the following structure: instead of the cap unit 1A, a cap unit 1B detachably attached to the container body 2 is provided.
Specifically, the cover unit 1B has substantially the same structure as the cover unit 1A described above, except that the shape of the lower surface of the inside plug 10 is different. That is, the lower surface of the inside plug 10 is provided with a lower surface convex portion 14. The lower surface convex portion 14 has a pointed shape in which the entire surface of the bottom wall portion 10a formed by the lower surface of the inside plug 10 is projected downward in a substantially conical shape. The lower surface convex portion 14 has an inclined surface 14a inclined linearly toward the lower surface center portion of the inside plug 10.
In the lidded container 100B of the present embodiment having the above-described configuration, in the state where the lid unit 1B is attached to the container main body 2, water droplets adhering to the lower surface of the inside plug 10 can be easily dropped toward the inside of the container main body 2 along the inclined surface 14a of the lower surface convex portion 14.
On the other hand, when the lid unit 1B is removed from the container body 2, water droplets adhering to the lower surface of the inside plug 10 flow into the gap S formed between the water stop pad 12 and the lower surface side protrusion 13 along the inclined surface 14a of the lower surface protrusion 14 due to the inclination of the lid unit 1B.
At this time, the amount of water droplets adhering to the lower surface of the inside plug 10 is smaller than in the case of the cover unit 1A, and the amount of water droplets accumulating in the gap S is suppressed. Therefore, the water droplets adhering to the lower surface of the inside plug 10 can be further suppressed from falling.
On the other hand, when the cover unit 1B is attached to the container body 2 again, the water droplets flowing into the gap S can be made to fall down to the inside of the container body 2 along the inclined surface 13a of the lower surface side protruding portion 13 and the inclined surface 14a of the lower surface convex portion 14.
As described above, in the lidded container 100B of the present embodiment, when the lid unit 1B is removed from the container main body 2, it is possible to suppress the periphery from being wetted by water droplets adhering to the lower surface of the inside plug 10. In addition, the container with a lid 100B of the present embodiment is provided with the lid unit 1B described above, thereby achieving further improvement in usability.

As shown in fig. 3, the container with a lid 100C of the present embodiment has the following structure: instead of the cap unit 1A, a cap unit 1C detachably attached to the container body 2 is provided.
Specifically, the cover unit 1C has substantially the same structure as the cover unit 1A described above, except that the shape of the lower surface of the inside plug 10 is different. That is, the lower surface of the inside plug 10 is provided with a lower surface convex portion 15. The lower surface convex portion 15 has a pointed shape in which the entire surface of the bottom wall portion 10a formed by the lower surface of the inside plug 10 is curved downward into a concave shape and protrudes in a substantially conical shape. The lower surface convex portion 15 has an inclined surface 15a which is curved in a concave shape toward the lower surface center portion of the inside plug 10 and is inclined.
In the lidded container 100C of the present embodiment having the above-described configuration, in the state where the lid unit 1C is attached to the container main body 2, water droplets adhering to the lower surface of the inside plug 10 can be easily dropped toward the inside of the container main body 2 along the inclined surface 15a of the lower surface convex portion 15.
On the other hand, when the lid unit 1C is removed from the container body 2, water droplets adhering to the lower surface of the inside plug 10 flow into the gap S formed between the water stop pad 12 and the lower surface side protrusion 13 along the inclined surface 15a of the lower surface protrusion 15 due to the inclination of the lid unit 1C.
At this time, the amount of water droplets adhering to the lower surface of the inside plug 10 is smaller than in the case of the lid unit 1A, and the amount of water droplets accumulating in the gap S is suppressed. Therefore, the water droplets adhering to the lower surface of the inside plug 10 can be further suppressed from falling.
On the other hand, when the lid unit 1C is attached to the container body 2 again, the water droplets flowing into the gap S can be made to fall down to the inside of the container body 2 along the inclined surface 13a of the lower surface side protruding portion 13 and the inclined surface 15a of the lower surface convex portion 15.
As described above, in the lidded container 100C of the present embodiment, when the lid unit 1C is removed from the container main body 2, it is possible to suppress the periphery from being wetted by water droplets adhering to the lower surface of the inside plug 10. Further, the container with a lid 100C according to the present embodiment is provided with the lid unit 1C described above, thereby achieving further improvement in usability.

Next, as embodiment 4 of the present invention, a lidded container 100D provided with a lid unit 1D shown in fig. 4, for example, will be described.
Fig. 4 is a cross-sectional view showing the structure of a lidded container 100D provided with a lid unit 1D. In the following description, the same portions as those of the lidded container 100A provided with the lid unit 1A are not described, and the same reference numerals are given to the drawings.
As shown in fig. 4, the container with a lid 100D of the present embodiment has the following structure: instead of the cap unit 1A, a cap unit 1D detachably attached to the container body 2 is provided.
Specifically, this cover unit 1D has basically the same structure as the above-described cover unit 1A, except that the shape of the lower surface of the inside plug 10 is different. That is, the lower surface of the inside plug 10 is provided with a lower surface convex portion 16. The lower surface convex portion 16 has a pointed shape in which a part of a bottom wall portion 10a formed by the lower surface of the inside plug 10 is projected downward in a substantially triangular shape. The lower surface convex portion 16 has an inclined surface 16a which is located at a position offset from the center of the lower surface of the inside plug 10 and which is inclined linearly toward the lower end thereof.
In the lidded container 100D of the present embodiment having the above-described configuration, in the state where the lid unit 1D is attached to the container body 2, water droplets adhering to the lower surface of the inside plug 10 can be easily dropped toward the inside of the container body 2 along the inclined surface 16a of the lower surface convex portion 16.
On the other hand, when the lid unit 1D is removed from the container body 2, water droplets adhering to the lower surface of the inside plug 10 flow into the gap S formed between the lower surface side protrusion 13 of the water stop packing 12 along the lower surface of the inside plug 10 due to the inclination of the lid unit 1D.
At this time, the amount of water droplets adhering to the lower surface of the inside plug 10 is smaller than in the case of the cover unit 1A, and the amount of water droplets accumulating in the gap S is suppressed. Therefore, the water droplets adhering to the lower surface of the inside plug 10 can be further suppressed from falling.
On the other hand, when the cover unit 1D is attached to the container body 2 again, the water droplets flowing into the gap S can be made to fall down to the inside of the container body 2 along the inclined surface 13a of the lower surface side protrusion 13.
As described above, in the lidded container 100D of the present embodiment, when the lid unit 1D is removed from the container main body 2, it is possible to suppress the periphery from being wetted by water droplets adhering to the lower surface of the inside plug 10. In addition, the container with a lid 100D of the present embodiment is provided with the lid unit 1D described above, thereby further improving the usability.
In the present embodiment, the lower surface of the inside plug 10 is provided with 1 lower surface convex portion 16, but the present invention is not necessarily limited to this configuration, and a plurality of lower surface convex portions 16 may be provided. The shape of the lower surface convex portion 16 can be appropriately changed.
(embodiment 5)
Next, as embodiment 5 of the present invention, a lidded container 100E provided with a lid unit 1E shown in fig. 5, for example, will be described.
Fig. 5 is a cross-sectional view showing the structure of a lidded container 100E provided with a lid unit 1E. In the following description, the same parts as those of the lidded container 100A provided with the lid unit 1A are not described, and the same reference numerals are given to the drawings.
As shown in fig. 5, the container with a lid 100E of the present embodiment has the following structure: instead of the cover unit 1A, a cover unit 1E detachably attached to the container body 2 is provided.
Specifically, the cover unit 1E has substantially the same structure as the cover unit 1A described above, except that the shape of the lower surface of the inside plug 10 is different. That is, the lower surface of the inside plug 10 is provided with a lower surface recess 17. The lower surface recess 17 has a spherical shape in which a bottom wall portion 10a formed by the lower surface of the inside plug 10 is recessed upward. The lower surface recess 17 has an inclined surface 17a that is curved in a concave shape from the center of the lower surface of the inside plug 10 toward the outer periphery and is inclined.
In the lidded container 100E of the present embodiment having the above-described configuration, in the state where the lid unit 1E is attached to the container main body 2, water droplets adhering to the lower surface of the inside plug 10 flow down from the center of the lower surface of the inside plug 10 toward the outer peripheral side along the inclined surface 17a of the lower surface concave portion 17. Thereafter, water droplets can be caused to fall down to the inside of the container body 2 along the inclined surface 13a of the lower surface side protruding portion 13 of the water stop pad 12.
On the other hand, when the lid unit 1E is removed from the container body 2, water droplets adhering to the lower surface of the inside plug 10 flow into the gap S formed between the water stop gasket 12 and the lower surface side protrusion 13 and the lower surface recess 17 along the inclined surface 17a of the lower surface recess 17 due to the inclination of the lid unit 1E.
At this time, the amount of water droplets adhering to the lower surface of the inside plug 10 is smaller than in the case of the lid unit 1A, and the amount of water droplets accumulating in the gap S is suppressed. Further, the gap S is secured larger than in the case of the cover unit 1A. Therefore, the water droplets adhering to the lower surface of the inside plug 10 can be further suppressed from falling.
On the other hand, when the cover unit 1E is attached to the container body 2 again, the water droplets flowing into the gap S and the lower surface recessed portion 17 can be made to fall toward the inside of the container body 2 along the inclined surface 13a of the lower surface side protruding portion 13.
As described above, in the lidded container 100E of the present embodiment, when the lid unit 1E is removed from the container body 2, it is possible to suppress the periphery from being wetted by water droplets adhering to the lower surface of the inside plug 10. Further, the container with a lid 100E according to the present embodiment is provided with the lid unit 1E described above, thereby achieving further improvement in usability.
(embodiment 6)
Next, as embodiment 6 of the present invention, a lidded container 100F provided with a lid unit 1F shown in fig. 6, for example, will be described.
Fig. 6 is a cross-sectional view showing the structure of a lidded container 100F provided with a lid unit 1F. In the following description, the same portions as those of the lidded container 100A provided with the lid unit 1A are not described, and the same reference numerals are given to the drawings.
As shown in fig. 6, the container with cap 100F of the present embodiment has the following structure: instead of the cover unit 1A, a cover unit 1F detachably attached to the container body 2 is provided.
Specifically, the cover unit 1F has substantially the same configuration as the cover unit 1A, except that the shape of the water seal packing 12 and the shape of the lower surface of the inside plug 10 are different. That is, the water stop packing 12 has a lower surface side protruding portion 18, and the lower surface side protruding portion 18 protrudes in the diameter reduction direction from a position contacting the outer peripheral portion on the lower surface side of the inside plug 10 over the entire circumference. On the other hand, a lower surface recess 17 is provided on the lower surface of the plug 10, similarly to the above-described cover unit 1E. Thereby, a gap S is provided between the upper surface of the lower surface side protruding portion 18 and the lower surface of the inside plug 10 over the entire circumference.
In the lidded container 100F of the present embodiment having the above-described configuration, when the lid unit 1F is removed from the container body 2, water droplets adhering to the lower surface of the inside plug 10 flow along the inclined surface 17a of the lower surface recessed portion 17 due to the inclination of the lid unit 1F into the gap S formed between the lower surface side protruding portion 18 of the water stop packing 12 and the lower surface recessed portion 17. In this case, water droplets are accumulated in the gap S and the lower surface concave portion 17, and the water droplets adhering to the lower surface of the inside plug 10 can be suppressed from falling.
Thus, in the lidded container 100F of the present embodiment, when the lid unit 1F is removed from the container body 2, it is possible to suppress the periphery from being wetted by water droplets adhering to the lower surface of the inside plug 10.
In the lidded container 100F of the present embodiment, the lower surface side protruding portion 18 of the water stop packing 12 is easily caught by the gap S formed between the lower surface of the inside plug 10 and the container. In this case, the water stop packing 12 can be easily removed from the inside plug 10 (the cap body 8) by grasping the lower surface side protruding portion 18 and elastically deforming (stretching and expanding) the water stop packing 12.
As described above, in the lidded container 100F of the present embodiment, when the lid unit 1F is removed from the container main body 2, it is possible to suppress the periphery from being wetted by water droplets adhering to the lower surface of the inside plug 10. In addition, the container with a lid 100F according to the present embodiment is provided with the lid unit 1F described above, thereby further improving usability.
(7 th embodiment)
Next, as embodiment 7 of the present invention, a lidded container 100G provided with a lid unit 1G shown in fig. 7, for example, will be described.
Fig. 7 is a cross-sectional view showing the structure of a lidded container 100G provided with a lid unit 1G. In the following description, the same parts as those of the lidded container 100A provided with the lid unit 1A are not described, and the same reference numerals are given to the drawings.
As shown in fig. 7, the container with a lid 100G of the present embodiment has the following structure: instead of the cap unit 1A, a cap unit 1G detachably attached to the container body 2 is provided.
Specifically, the cover unit 1G has substantially the same configuration as the cover unit 1A, except that the shape of the water seal packing 12 and the shape of the lower surface of the inside plug 10 are different. That is, the water seal packing 12 has a lower surface side protruding portion 18, similarly to the cover unit 1F described above, and the lower surface side protruding portion 18 protrudes in the diameter reduction direction from a position contacting the outer peripheral portion on the lower surface side of the inside plug 10 over the entire circumference. On the other hand, a lower surface convex portion 14 is provided on the lower surface of the inner plug 10, similarly to the above-described cover unit 1B. Further, the bottom wall portion 10a constituting the lower surface convex portion 14 is connected to a position above the lower end of the reduced diameter portion 10 c. Thereby, a gap S is provided between the upper surface of the lower surface side protruding portion 18 and the lower surface of the inside plug 10 over the entire circumference.
In the lidded container 100G of the present embodiment having the above-described configuration, in the state where the lid unit 1G is attached to the container main body 2, water droplets adhering to the lower surface of the inside plug 10 can be easily caused to fall toward the inside of the container main body 2 along the inclined surface 14a of the lower surface convex portion 14.
On the other hand, when the lid unit 1G is removed from the container body 2, water droplets adhering to the lower surface of the inside plug 10 flow into the gap S formed between the water stop pad 12 and the lower surface side protrusion 18 along the inclined surface 14a of the lower surface protrusion 14 due to the inclination of the lid unit 1G.
At this time, the amount of water droplets adhering to the lower surface of the inside plug 10 is smaller than in the case of the cover unit 1A, and the amount of water droplets accumulating in the gap S is suppressed. Therefore, the water droplets adhering to the lower surface of the inside plug 10 can be further suppressed from falling.
Thus, in the lidded container 100G of the present embodiment, when the lid unit 1G is removed from the container body 2, it is possible to suppress the periphery from being wetted by water droplets adhering to the lower surface of the inside plug 10.
In the capped container 100G of the present embodiment, the lower surface side protrusion 18 of the water seal packing 12 is easily caught by the gap S formed between the lower surface of the inside plug 10 and the bottom surface. In this case, the water stop packing 12 can be easily removed from the inside plug 10 (the cap body 8) by grasping the lower surface side protruding portion 18 and elastically deforming (stretching and elongating) the water stop packing 12.
As described above, in the lidded container 100G of the present embodiment, when the lid unit 1G is removed from the container main body 2, it is possible to suppress the periphery from being wetted by water droplets adhering to the lower surface of the inside plug 10. Further, the container with a lid 100G of the present embodiment is provided with the lid unit 1G described above, thereby achieving further improvement in usability.
(embodiment 8)
Next, as embodiment 8 of the present invention, for example, the lower surface side protrusions 19 and 20 shown in fig. 8A and B will be described.
Fig. 8A is a main part sectional view showing the structure of the lower surface side protrusion 19. Fig. 8B is a main part sectional view showing the structure of the lower surface side protrusion 20. In the following description, the same parts as those of the water stop cover 12 are not described, and the same reference numerals are given to the drawings.
The water stop packing 12 shown in fig. 8A and 8B has lower surface side protruding portions 19 and 20, and the lower surface side protruding portions 19 and 20 protrude in a direction away from each other from positions contacting the lower surface of the inside plug 10 over the entire circumference. The lower surface side protrusion 19 shown in fig. 8A has a perpendicular surface 19a perpendicular to the lower surface of the inside plug 10 on the inner peripheral side thereof. On the other hand, the lower surface side protrusion 20 shown in fig. 8B has an inverted inclined surface 20a which forms an obtuse angle with respect to the lower surface of the inside plug 10 on the inner peripheral side thereof.
When the water stop packing 12 having such a structure is used, water droplets adhering to the lower surface of the inside plug 10 can fall down to the inside of the container body 2 along the vertical surface 19a of the lower surface side protrusion 19 and the inclined surface 20a of the lower surface side protrusion 20.
Therefore, the water seal packing 12 shown in fig. 8A and B is suitable for use in the cover unit provided with the lower surface recess 17 described above. That is, in a state where the lid unit is attached to the container body 2, water droplets adhering to the lower surface of the inside plug 10 flow down from the center of the lower surface of the inside plug 10 toward the outer peripheral side along the inclined surface 17a of the lower surface recessed portion 17. Thereafter, the water droplets can be made to fall toward the inside of the container body 2 along the vertical surface 19a of the lower surface side protruding portion 19 of the water stopping pad 12 and the inverted slope surface 20a of the lower surface side protruding portion 20.
This can prevent the periphery from being wetted by water droplets adhering to the lower surface of the inside plug 10 when the lid unit is removed from the container body 2.
(embodiment 9)
Next, as embodiment 9 of the present invention, for example, a configuration in which shape changing portions 21A to 21D are provided in a part of the lower surface side protruding portion 13 as shown in fig. 9A to 9D will be described.
Fig. 9A is a sectional perspective view of main parts showing the structure of the shape changing portion 21A. Fig. 9B is a sectional perspective view of main parts showing the structure of the shape changing portion 21B. Fig. 9C is a sectional perspective view of main parts showing the structure of the shape changing portion 21C. Fig. 9D is a sectional perspective view of main parts showing the structure of the shape changing portion 21D. In the following description, the same parts as those of the water stop cover 12 are not described, and the same reference numerals are given to the drawings.
The water stop pad 12 shown in fig. 9A to 9D has shape changing portions 21A to 21D, and the shape changing portions 21A to 21D change the shape of a part of the lower surface side protruding portion 13. The shape changing portion 21A shown in fig. 9A is formed of a substantially V-shaped notch portion formed by partially cutting out the lower surface side protruding portion 13. On the other hand, the shape changing portion 21B shown in fig. 9B is formed of a groove portion having a substantially V-shaped cross section, which is located on the inner peripheral side of the lower surface side protruding portion 13 and gradually widens downward in width. On the other hand, the shape changing portion 21C shown in fig. 9C is formed of a protruding piece in which a part of the lower surface side protruding portion 13 is pointed from the distal end side. On the other hand, the shape changing portion 21D shown in fig. 9D is formed of a brim portion in which a part of the lower surface side protruding portion 13 is formed to protrude in a pointed shape from the inner peripheral side in the diameter reduction direction.
In the case of using the water seal packing 12 having such a structure, the liquid break of the water droplets accumulated in the gap S is improved, and the water droplets accumulated in the gap S can be dropped into the container main body 2 along the shape changing portions 21A to 21D. The shape changing portions 21A to 21D are also effective when the user intentionally shakes off water droplets accumulated in the gap S.
(embodiment 10)
Next, as a 10 th embodiment of the present invention, for example, a container 100H with a lid provided with a lid unit 1H shown in fig. 10 will be described.
Fig. 10 is a cross-sectional view showing the structure of a lidded container 100H provided with a lid unit 1H. In the following description, the same parts as those of the lidded container 100A provided with the lid unit 1A are not described, and the same reference numerals are given to the drawings.
As shown in fig. 10, the container with a lid 100H of the present embodiment has the following structure: instead of the cap unit 1A, a cap unit 1H detachably attached to the container body 2 is provided.
Specifically, the cover unit 1H has substantially the same structure as the cover unit 1A described above, except that the shape of the lower surface of the inside plug 10 is different. That is, at least 1 or a plurality of (3 in the present embodiment) lower surface protrusions 22 are provided on the lower surface of the plug 10, and the lower surface protrusions 22 are formed in a ring shape (circular shape in the present embodiment) in a plan view.
The plurality of lower surface protrusions 22 are arranged concentrically from the center of the lower surface of the inside plug 10. Each lower surface convex portion 22 has a pointed shape protruding downward from a bottom wall portion 10a constituting the lower surface of the inside plug 10 in a substantially triangular shape in cross section.
In the present embodiment, the lower surface convex portions 22 are arranged concentrically from the center thereof, but 1 lower surface convex portion 22 may be arranged. Further, the inner plug 10 may be disposed so as to be offset from the center of the lower surface thereof. The lower surface convex portion 22 is not limited to the above-described case of being formed in a circular shape in a plan view, and may be formed in an elliptical shape, for example. The lower surface convex portion 22 is not limited to the above-described pointed shape protruding in a substantially triangular shape in cross section, and may be a shape protruding in a thin plate shape. The lower surface convex portion 22 can also be formed by shrinkage of the resin material when the inside plug 10 is molded.
In the lidded container 100H of the present embodiment having the above-described configuration, in the state where the lid unit 1H is attached to the container body 2, water droplets adhering to the lower surface of the inside plug 10 can be easily dropped toward the inside of the container body 2 along the lower surface convex portion 22.
On the other hand, when the cap unit 1H is removed from the container body 2, the cap 1H is rotated with respect to the container body 2 in a direction to release the engagement between the male screw portion 11 and the female screw portion 6. At this time, water droplets adhering to the lower surface of the inside plug 10 can be caused to fall down to the inside of the container body 2 along the lower surface convex portion 22 by the centrifugal force acting on the inside plug 10.
On the other hand, when the lid unit 1H is removed from the container body 2, water droplets adhering to the lower surface of the inside plug 10 flow into the gap S formed between the lower surface side protrusion 13 of the water stop packing 12 along the lower surface of the inside plug 10 due to the inclination of the lid unit 1H.
In this case, by accumulating water droplets in the gap S, it is possible to suppress the water droplets adhering to the lower surface of the inside plug 10 from falling. In the cover unit 1H of the present embodiment, water droplets adhering to the lower surface of the inside plug 10 are smaller than in the case of the cover unit 1A, and the amount of water droplets accumulating in the gap S is suppressed. Therefore, the water droplets adhering to the lower surface of the inside plug 10 can be further suppressed from falling.
Thus, in the lidded container 100H of the present embodiment, when the lid unit 1H is removed from the container body 2, it is possible to suppress the periphery from being wetted by water droplets adhering to the lower surface of the inside plug 10.
In the capped container 100H of the present embodiment, the lower surface side protrusion 18 of the water seal packing 12 is easily caught by the gap S formed between the lower surface of the inside plug 10 and the bottom surface. In this case, the water stop packing 12 can be easily removed from the inside plug 10 (the cap body 8) by grasping the lower surface side protruding portion 18 and elastically deforming (stretching and expanding) the water stop packing 12.
As described above, in the lidded container 100H of the present embodiment, when the lid unit 1H is removed from the container main body 2, it is possible to suppress the periphery from being wetted by water droplets adhering to the lower surface of the inside plug 10. Further, the container with a lid 100H according to the present embodiment can be further improved in usability by including the lid unit 1H described above.
The present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the present invention.
For example, the cover units 1A to 1H may be configured such that: the inner plug 10 is provided with fine irregularities on a part or the entire lower surface thereof. For the concave-convex processing, for example, texturing processing or the like can be performed on the surface of the bottom wall portion 10a constituted by the lower surface of the inside plug 10.
In the cover units 1A to 1H, the surface area of the lower surface of the inside plug 10 subjected to the uneven processing is increased, and water droplets adhering to the lower surface of the inside plug 10 can be grown larger. This makes it possible to easily drop the water droplets that have grown large to the inside of the container body 2. When the cover units 1A to 1H are removed from the container main body 2 and the cover units 1A to 1H are attached again, the water droplets growing largely can be caught in the surrounding water droplets and easily fall down to the inside of the container main body 2.
The lid units 1A to 1H are configured such that the inside plug 10 is attached to the container body 2 by screwing in a state of being fitted from the upper opening 2a of the container body 2 to the inside. For example, the cover units 1A to 1H may be configured such that: the outer lid 9 is attached to the container body 2 by screwing in a state where the upper opening 2a of the container body 2 is covered from the outside.
In the case of this structure, the following structure may be adopted: instead of the female screw portion 6 and the male screw portion 11, the outer lid 9 (lid body 8) is detachably attached to the container body 2 by screwing the male screw portion provided on the outer peripheral surface of the mouth-and-neck portion 2d and the female screw portion provided on the inner peripheral surface of the peripheral wall portion 9a constituted by the outer lid 9.
The lid units 1A to 1H 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, the following configuration may be adopted: the lid body is openably and closably attached to a lid main body attached to the container main body 2.
In this configuration, the lid body may be attached to the lid main body by screwing, or the lid body may be attached to the lid main body via a hinge portion so as to be rotatable.
In the above-described embodiment, the case where the present invention is applied to the beverage container having the heat retaining function (or the cold retaining function) due to the container body 2 having the vacuum heat insulating structure is exemplified, but the present invention can be widely applied to a lidded container including a container body and a lid unit detachably attached to the container body.
