Description

The present invention relates to a ventilation device, and more particularly to a ventilation device having a blower section that blows air into a container that holds a chilled beverage.

Soft drinks are widely consumed, and are especially popular in the summer to cool down. For example, Patent Document 1 discloses an example in which frozen soft drinks or other beverages are placed in a container to cool down in the summer.

Japanese Patent Application Laid-Open No. 2020-89316

In the summer, people sometimes cool down by placing a container of frozen beverage directly against their skin. However, when cooling down in this way, moisture in the air that has reached its dew point adheres to the surface of the container, making the skin wet and causing an uncomfortable feeling. For this reason, there has been a demand for the development of a device that can cool down by using air instead of directly touching the container.

The present invention was made in light of these circumstances, and aims to provide a ventilation device that can deliver air that is cooled by the influence of a cooled beverage.

To achieve the above objective, the invention relating to a ventilation device is characterized by having a first blowing section that blows air cooled by the influence of a cooled beverage, and a circulation section through which the air blown from the first blowing section circulates.

According to the present invention, the above configuration allows for the delivery of air that is cooled by the influence of the cooled beverage.

It has a first container in which the cooled beverage is placed, and the circulation unit can circulate air sent from the first air blowing unit on the outer surface side of the first container.

It has a second container for holding the first container, and the second container can be made of a deformable material.

In other words, when the first container is placed inside, the second container deforms to correspond to the shape of the outer surface of the first container, thereby making contact with the outer surface of the first container.

The second container is provided with a heat conductor made of a heat-conductive material, and the circulation section circulates air sent from the first blower section to the second container, and the heat conductor comes into contact with the air circulating through the circulation section, so that the air can be cooled via the heat conductor.
The heat conductor may include at least a metal.
The heat conductor may have grooves formed therein that extend in the direction in which the air flows.

A second blower is provided, which can send the air sent from the first blower further downstream.

If the second blower has a detachable part for attaching and detaching the second blower to the second container, the second blower can be attached and detached to the second container.

By having a second container for containing the first container, and also having a second circulation section with the circulation section serving as the first circulation section, and the second circulation section being connected to the second container and having a hollow interior through which air sent from the first blower section flows, cooled air can be sent through the second circulation section.

If the second flow section is made extendable, the length of the second flow section can be changed.

The first container has a hollow through-hole, and if the hollow through-hole functions as a circulating portion through which the air sent by the first blower circulates, the air sent by the first blower can circulate through the through-hole.

The hollow through-hole can be located in the center of the first container and extend in the vertical direction.

A second container may be provided for receiving the first container.
The container may have a cover member that covers the outer surface of the first container, and a predetermined space may be interposed between the cover member and the outer surface of the first container, and the space may be a circulation section through which the air flows.
If the cover member has a predetermined opening/closing portion and is configured to be openable and closable, the first container can be taken in and out by opening and closing the opening/closing portion.

The opening/closing section includes a vertical opening/closing section that opens and closes the cover member from top to bottom, and a circumferential opening/closing section whose one end is continuous with the lower end of the vertical opening/closing section and opens and closes the cover member in the circumferential direction. The other end of the circumferential opening/closing section is a discontinuous section that is discontinuous with both the lower end of the vertical opening/closing section and the one end of the circumferential opening/closing section. The upper side of the circumferential opening/closing section on the cover member is the main body of the cover member, and the lower side of the circumferential opening/closing section on the cover member is the lower edge of the cover member. The main body of the cover member and the lower edge of the cover member are continuous with each other, with the cover member interposed between the other end of the circumferential opening/closing section and the lower end of the vertical opening/closing section and the one end of the circumferential opening/closing section, so that even when the opening/closing section is fully opened, the cover member does not separate and the next closing operation can be performed quickly.

The first blower may be provided below the first container.
By providing a second air blowing section above the first container that sucks in air sent from the first air blowing section and sends the sucked air out, the first air blowing section and the second air blowing section can reliably circulate the air through the circulation section while sending it out to the outside.

The cover member has an opening at the top end and a dome-shaped lid for closing the opening. The second air blower is provided inside the lid, and the lid can be provided with an outlet for blowing air drawn in by the second air blower to the outside.

If a plurality of heat conductors made of a heat conductive material are provided on the outer side of the first container, the air can be cooled via the heat conductors.
If the heat conductor has an air contact portion that comes into contact with the circulating air and a container contact portion that is continuous with the air contact portion and comes into contact with the first container side, the cooled temperature can be conducted from the container side to the air side.

If the container contact portion is in contact with the first container side via a material that is heat-dissipating and/or elastic, the cooled temperature of the first container side can be conducted to the container contact portion so as to dissipate heat, and/or the container contact portion can be brought into close contact with the shape of the first container side to correspond to the shape of the first container side.
If the container contact portion is in contact with the first container side via a thermoelectric element, it is possible to heat the first container side and cool the air contact portion side.

The device has a band-shaped elastic member that stretches and contracts in a predetermined manner, and the elastic member has an insertion hole through which the thermal conductor is inserted. The middle part of the thermal conductor is inserted into the insertion hole to expose the air contact part and the container contact part from the elastic member, and is arranged to connect adjacent thermal conductors. By attaching the elastic member to the outer side of the first container, the thermal conductor can be arranged on the outer side of the first container.

The elastic member is provided with a hook-and-loop fastener, which has a male hook-and-loop fastener provided on one end of the elastic member and a female hook-and-loop fastener provided on the other end of the strip-shaped member. By engaging the male hook-and-loop fastener with the female hook-and-loop fastener with each other, the elastic member can be attached to the outer lateral surface of the first container.

The present invention allows for the delivery of air that is cooled by the influence of the cooled beverage.

[First embodiment]
A first embodiment of the present invention will be described in detail below with reference to the drawings. Fig. 1 is a side view showing the overall configuration of a ventilation device according to the first embodiment of the present invention, Fig. 2 is a view showing a second container in the ventilation device, Fig. 3 is a view showing a first blower in the ventilation device, Fig. 4 is a view showing the configuration of a thermal conductor in the ventilation device, Fig. 5 is a view showing a second blower in the ventilation device, and Fig. 6 is a view showing a detachable part in the ventilation device. In the following description, directions are defined relative to the first container 10, and the upper side of the first container 10 (the second blower 40 side) is referred to as "upper," the lower side (the first blower 30 side) is referred to as "lower" (bottom side), and the thermal conductor 25 side is referred to as "side," and each direction is also clearly indicated in the drawings.

The ventilation device 1 of this first embodiment will be outlined with reference to Figures 1 to 6. The ventilation device 1 has a first container 10, a second container 20, a first blower section 30, a second blower section 40, and a detachable section 50.

As shown in Figures 1 and 2, the first container 10 can hold a chilled beverage A, which can be frozen water, a soft drink, or the like. The first container 100 can be a plastic bottle, as shown in the figures, or can be a water bottle or other container capable of holding beverage A.

The second container 20 can hold the first container 10. The second container 20 has a large downward recess 21b in the center, as well as an upper portion 21, side portions 22, and a bottom portion 23. The second container 20 has an opening 21a in the center of the upper portion 21, which is connected to the recess 21b.

In other words, the opening 21a functions as an insertion port for inserting the first container 10 into the recess 21b, and the recess 21b functions as a storage section for storing the first container 10. The second container 20 is held in place so that the inner surfaces 27 of the sides 22 and bottom 23 facing the recess 21b cover the sides 12 and bottom 12 of the first container 10.

The second container 20 can be made of a deformable material. The deformable material can be a material that has elasticity and can be elastically deformed. The elastically deformable material can be silicone, urethane, etc. Silicone and urethane are elastically deformable and have stretchability.

The second container 20 is made of an elastically deformable material, so that when the first container 10 is placed in the recess 21b, the recess 21b elastically deforms to correspond to the shape of the outer surface 10a of the first container 10, and can come into contact with the outer surface 10a of the first container 10 (when the first container 10 is removed from the recess 21b, the second container 20 returns to its original shape).

As shown in Figures 1 and 3, the first air blowing unit 30 can blow air that is cooled by the influence of the cooled beverage A. The first air blowing unit 30 can blow air toward the first container 10. The first air blowing unit 30 has blades 32 provided inside a short cylindrical casing 31, and the blades 32 are attached to the casing 31 via a rotating shaft 33. The first air blowing unit 30 can blow air by applying the required power to the rotating shaft 33 to rotate it.

In other words, the second container 20 is hollow, and the hollow interior 20' functions as a circulating section 20' through which air sent from the first blower 30 toward the first container 10 circulates. In other words, the circulating section 20' can circulate air sent from the first blower 30 on the outer surface 10a side of the first container 10. In addition, the circulating section 20' can circulate air sent from the first blower 30 to the second container 20.

More specifically, the second container 20 has a first air blowing section 30 on the outer surface 26 side of the bottom 23 of the hollow interior 20', and multiple holes 24 are provided at the upper end of the second container 20, which function as outlets for the air sent from the first air blowing section 30. That is, a hole 26' is provided on the outer surface 26 side of the bottom 23 of the second container 20, and the first air blowing section 30 is fitted into the hole 26'.

In other words, the first air blowing section 30 is in communication with the outside air side and the interior 20' side of the second container 20, and can send outside air to the interior 20' of the second container 20. This creates a cooling air circulation path that runs from the first air blowing section 30 provided on the bottom 23 of the second container 20, through the hollow interior 20' in the side section 22, and to the hole 24 at the top end. The second container 20 also has a groove 20'' on the upper end side, into which the lower end of the detachable section 50 can be fitted.

Here, the second container 20 is provided with a thermal conductor 25, as shown in Figures 1, 2, and 4. The thermal conductor 25 is made of a thermally conductive material. The thermal conductor 25 may contain at least a metal, and the metal may be, for example, iron or copper.

The thermal conductor 25 is provided on the inner surface 27 side of the second container 20 .
More specifically, the thermal conductor 25 has a first exposed portion 25a exposed on the side facing the held first container 10, and a second exposed portion 25b exposed on the side of the hollow interior 20' of the second container 20. The second exposed portion 25b has a groove 25' extending along the air flow direction. As such, by having the exposed portions 25a and 25b, the thermal conductor 25 comes into contact with air flowing through the outer surface 10a of the first container 20 and the hollow interior 20' of the second container 20, more specifically, the air flowing through the flow portion 20', and the flowing air can be cooled by the first container 10 via the thermal conductor 25. Furthermore, since the thermal conductor 25 has the groove 25' extending along the air flow direction, the cooling area can be increased.

As shown in Figures 1 and 5, the second blower 40 is provided on the upper end side of the second container 20. The second blower 40 is in communication with the hollow interior 20' of the second container 20 via the holes 24 of the second container 20. The second blower 40 can send the air sent from the first blower 30, which is ejected through the holes 24, further downstream. The air sent by the second blower 40 allows the user of the ventilation device 1 to feel cool. The second blower 40 has blades 42 provided inside a short cylindrical casing 41, and the blades 41 are attached to the casing 41 via a rotating shaft 43. The second blower 40 can send air by applying power as required to the rotating shaft 43 to rotate it.

In addition, a groove 44 is provided on the underside of the second blower section 40, and the upper end of the detachable section 50 can be fitted into the groove 44.

As shown in Figures 1 and 6, the detachable part 50 is used to attach and detach the second blower 40 to the upper end of the second container 20. The detachable part 50 has a short cylindrical part 50a on the upper side and a dome-shaped part 50b on the lower side that connects to the lower end of the cylindrical part 50a. That is, the upper end of the cylindrical part 50a of the detachable part 50 is removably fitted into the groove 44 on the underside of the second blower 40, and the lower end of the dome-shaped part 50b is removably fitted into the groove 20'' on the upper end of the second container 20, thereby allowing the second blower 40 to be attached and detached to the upper end of the second container 20.

The method of assembling the ventilation device 1 configured in this manner will be described below.
That is, as shown in FIG. 8, the first blower 30 is fitted into the hole 26' on the outer surface 26 of the bottom 23 of the second container 20 shown in FIG. 7. Next, as shown in FIGS. 9 and 10, the first container 10 is placed in the recess 21b through the opening 21a of the second container 20. When the first container 10 is placed in the recess 21b, the recess 21b elastically deforms to correspond to the shape of the outer surface 10a of the first container 10, allowing it to come into contact with the outer surface 10a of the first container 10. Next, as shown in FIG. 11, the lower end of the detachable part 50 is fitted into the groove 20'' on the upper end side of the second container 40. Next, as shown in FIG. 1, the second blower 40 is fitted into the groove 44 on the lower surface side, and the ventilation device 1 is assembled.

As described above, according to the first embodiment, there is a first air blowing section 30 that blows air cooled by the influence of the cooled beverage A, and a circulation section 20' through which the air blown from the first air blowing section 30 circulates, so that air cooled by the influence of the cooled beverage A can be blown.

Furthermore, the second container 20 is provided with a thermal conductor 25 made of a thermally conductive material, and the thermal conductor 25 is in contact with the circulating air, so the air can be cooled via the thermal conductor 25.

Furthermore, by using the second container 20 to contain the first container 10, it is possible to reduce the amount of moisture in the air that reaches the dew point adhering to the surface of the container.

[Second embodiment]
A second embodiment of the present invention will be described in detail below with reference to the drawings. Fig. 12 is a side view showing the configuration of a ventilation device according to the second embodiment of the present invention. Fig. 13 is a side view showing the configuration of an air channel and an air blower of the ventilation device according to the second embodiment, and Fig. 14 is a view showing a connecting portion of the ventilation device.

The ventilation device 2 according to this second embodiment has a second circulating section 60 instead of the second blowing section 40 of the ventilation device 1 according to the first embodiment described above.

In other words, in this second embodiment, the interior 20' of the second container 20 in the first embodiment described above, i.e., the circulating section 20', serves as the first circulating section 20', and the added circulating section serves as the second circulating section 60. The ventilation device 2 according to the second embodiment can send cooled air to the user via the second circulating section 60.

The second flow section 60 is provided on the upper end side of the second container 20. The second flow section 60 has an air duct section 61, a third air blowing section 62, and a connecting section 63. The second flow section 60 is configured such that, from the upstream side, i.e., the starting end, the connecting section 63, the third air blowing section 62, the air duct section 61, the third air blowing section 62, the air duct section 61, the third air blowing section 62, and the air duct section 61 are arranged in this order. The second flow section 60 is in communication with the hollow interior 20' (flow section 20'') of the second container 20 via the hole 24 of the second container 20.

There are multiple air ducts 61, each formed in a long, cylindrical shape with a predetermined length. The air ducts 61 have a hollow interior 61' through which air sent from the first blower 30 flows. The air ducts 61 are expandable and contractible along the longitudinal direction. The air ducts 61 may have a bellows structure and may contain electrical wires.

The third blower 62 is provided in multiple locations and can send the air sent from the first blower 30, which is ejected through the holes 24, further downstream. The air sent by the third blower 62 allows the user of the ventilation device 2 to cool down. The third blower 62 has blades 62b provided inside a short cylindrical casing 62a, and the blades 62b are attached to the casing 62a via a rotating shaft 62c. The second blower 62 can send air by applying the required power to the rotating shaft 62c to rotate it. In addition, a groove 62e is provided on the underside of the third blower 62, and the upper end of the connecting portion 63 can be fitted into the groove 62e.

The connecting portion 63 can detachably connect the second flow section 60 to the upper end of the second container. The connecting portion 63 has a short cylindrical portion 63a on the upper side and a dome-shaped portion 63b on the lower side that connects to the lower end of the cylindrical portion 63a. That is, the upper end of the cylindrical portion 63a of the connecting portion 63 is detachably fitted into the groove 62e on the underside of the third blower 62, and the lower end of the dome-shaped portion 63b is detachably fitted into the groove 20'' on the upper end of the second container 20, thereby detachably connecting the third blower 62 to the upper end of the second container 20.

With the ventilation device 2 of the second embodiment configured in this manner, even when the user is using the ventilation device 2 at a distance, the long second circulating section 60 can act to keep the user cool. The second circulating section 60 is extendable, so the length of the second circulating section 60 can be changed.

[Third embodiment]
A third embodiment of the present invention will now be described in detail with reference to the drawings. Fig. 15 is a front cross-sectional view showing the configuration of a ventilation device 3 according to the third embodiment of the present invention, and Fig. 16 is an exploded front view showing the overall configuration of the ventilation device 3.

The ventilation device 3 according to this third embodiment comprises a first container 100, a blower 1110, and a second container 120, with a through-hole 101 provided in the first container 100.

That is, the first container 100 is cylindrical and annular in plan view, and has a hollow through-hole 101 that runs through it. The through-hole 101 is located in the center of the first container 100 and extends in the vertical direction. The first container 100 is further hollow between the annular inner surface 100a that forms the through-hole 101 and the annular outer surface 100b, and the hollow interior 102 can hold cooled beverage A.

The first container 100 has a hole 105 on the upper side, and by removing the cap 106, the hollow interior 102 can be connected to the outside through the hole 106. In other words, by removing the cap 106, beverage A can be poured into the hollow interior 102 through the hole 105 to refill it, and the user can drink beverage A from the hollow interior 102 through the hole 105. The first container 100 is made of a thermally conductive material.

The blower 110 is fitted into the lower end of the through-hole 101 and can blow air that is cooled by the influence of the cooled beverage A. The blower 110 can blow air toward the first container 100 through the through-hole 101. The blower 110 has blades 112 provided inside a short cylindrical casing 111, and the blades 112 are attached to the casing 31 via a rotating shaft 113. The first blower 30 can blow air by applying power to the rotating shaft 113 as required to rotate it.
That is, the hollow through-hole portion 101 can function as a circulating portion 101 through which the air sent by the blower portion 110 circulates.

The second container 120 is used to contain the first container 100, which is made of a thermally conductive material. The second container 120 is box-shaped and concave. That is, the top 121 of the second container 120 has an opening 121a, which functions as an insertion section for inserting the first container 100 together with the first blower section 110. The side sections 122 and bottom section 123 of the second container 120 function as holding sections that cover the side sections 103 and bottom section 104 of the first container 100 with their inner surfaces 122a and 123a. Because the second container 120 contains the first container 100, it is possible to reduce adhesion of moisture in the air that has reached the dew point to the surface of the container.

[Fourth embodiment]
A fourth embodiment of the present invention will now be described in detail with reference to the drawings. Fig. 15 is a front cross-sectional view showing the configuration of a ventilation device 3 according to a third embodiment of the present invention, and Fig. 16 is an exploded front view showing the overall configuration of the ventilation device 3.

The ventilation device 3 according to this third embodiment comprises a first container 100, a blower 1110, and a second container 120, with a through-hole 101 provided in the first container 100.

It should be noted that the present invention is not limited to the first to third embodiments described above, and various modifications and applications are possible.
That is, for example, as shown in the modified example of FIG. 17 , a rotor 28 such as a motor can be provided at the lower end of the recess 21b of the second container 20 in the first and second embodiments, and the rotor 28 can rotate the first container 10. By rotating the first container 10 in this manner, the air sent from the first blower 30 can be efficiently cooled. Note that a non-slip member 29 can be provided between the rotor 28 and the bottom 13 of the first container 10, and the non-slip member 29 can reduce slippage of the first container 10 during rotation. The non-slip member 29 is made of, for example, rubber, and has a groove 29b on its upper surface 29a to prevent the first container 10 from slipping.

Also, as in the modified example shown in Figures 18 and 19, the first container 10 may be placed in the recess 21b of the second container 20 via a specified attachment 70. That is, the attachment 70 has an insertion portion 71 in the center into which the first container 10 is inserted, and the attachment 70 can be placed in the recess 21b of the second container 20 with the first container 10 inserted into the insertion portion 71. The insertion portion 71 has a shape that corresponds to the shape of the outer surface side of the first container 10. That is, the shape of the outer surface 73 side of the attachment 70 when viewed from above is more specifically circular rather than arc-shaped.

As a result, even if the first container 10 is, for example, prismatic, it can be cooled while rotating in a ventilation device 1 having a rotor 28 as shown in Figure 17 by inserting the first container 10 into the recess 21b of the second container 20 via the attachment 70. Note that, as shown in Figure 20, the attachment 70 may have a member 74 with multiple arc-shaped outer surfaces, giving the outer surface 73 an approximately circular shape.

In addition, in the ventilation device 3 of the third embodiment described above, it is of course possible to provide an additional ventilator at the upper end of the first container 10, or to provide a long second flow section.

Alternatively, the ventilation device 4 may be configured as in the modified examples shown in Figures 21 to 25. That is, the ventilation device 4 has a cover member 80 that covers the lateral outer surface 10a of the first container 10 in which the cooled beverage A is placed, forming a second container, and a predetermined space is provided between the cover member 80 and the lateral outer surface 10a of the first container 10, and this space serves as a circulation section 80' through which air flows.

In other words, the cover member 80 has a specified opening/closing portion 81 that can be opened and closed, and the opening/closing portion 81 can be opened and closed via a specified zipper fastener A. The first container 10 can be inserted and removed by opening and closing the opening/closing portion 81.

The opening/closing portion 81 has a vertical opening/closing portion 81a that opens and closes the cover member 80 from top to bottom, and a circumferential opening/closing portion 82a whose lower end 81a' and one end 82a' of the vertical opening/closing portion 81a are continuous and which opens and closes the cover member 80 in the circumferential direction. The other end 82a'' of the circumferential opening/closing portion 82a is discontinuous from both the lower end 81a' of the vertical opening/closing portion 81a and the one end 82a' of the circumferential opening/closing portion 82a. The upper side of the circumferential opening/closing portion 82a on the cover member 80 is the main body portion 80a of the cover member 80, and the lower side of the circumferential opening/closing portion 82a on the cover member 80 is the lower edge portion 80b of the cover member 80. The main body 80a of the cover member 80 and the lower edge 80b of the cover member 80 are continuous due to the discontinuity, with the cover member 80 interposed between the other end 82a'' of the circumferential opening/closing portion 82a and the lower end 81a' of the vertical opening/closing portion 81a and one end 82a' of the circumferential opening/closing portion 82a. This prevents the cover member 80 from separating even when the opening/closing portion 81 is fully opened, allowing the next closing operation to be performed quickly.

In the ventilation device 4, the first blower 30 is provided below the first container 10, and a second blower 40 is further provided above the first container 10. The second blower 40 can suck in air sent from the first blower 30 and send the sucked air to the outside. The first blower 30 and the second blower 40 can reliably circulate air through the circulation section 80' while sending it to the outside.

The cover member 80 has an opening 80d at the upper end 80c and a dome-shaped lid body 83 for closing the opening 80d, and the second blower 40 is provided inside the lid body 83. The lid body 83 is provided with a blower opening 84 that blows air drawn in by the second blower 40 to the outside.

Here, a plurality of thermal conductors 90 made of a thermally conductive material are provided on the outer surface 10a of the side of the first container 10, and air can be cooled via the thermal conductors 90. The thermal conductors 90 can include at least a metal, and the metal can be, for example, iron or copper.
The thermal conductor 90 is generally H-shaped and includes a first flat plate portion 91, a second flat plate portion 92, and a third flat plate portion 93 perpendicular to the first flat plate portion 91 and the second flat plate portion 92. The first flat plate portion 91, the second flat plate portion 92, and the third flat plate portion 93 form a base of the thermal conductor 90. The third flat plate portion 93 is provided with a plurality of thin fins 94 parallel to the first flat plate portion 91 and the second flat plate portion 92. The thermal conductor 90 contacts the air flowing through the flow portion 80', and the outer surface 92a of the second flat plate portion 92 forms a container contact portion 92a that contacts the first container 10. The container contact portion 92a allows the cooled temperature to be conducted from the container 10 to the air.

The container contact portion 92a contacts the first container 10 side via a heat-dissipating and/or elastic material 93, which is made of silicon. This allows the cooled temperature on the first container 10 side to be conducted to the container contact portion 92a so as to dissipate heat, and/or allows the container contact portion 92a to be in intimate contact with the shape of the first container 10 side.

The container contact portion 92a is in contact with the first container 10 side via a thermoelectric element 94. The thermoelectric element 94 can heat the first container 10 side and cool the thermal conductor 90 side by passing an electric current through it. The thermoelectric element 94 can be a Peltier element.

The ventilation device 4 of this modified example has a band-shaped elastic member 95 that expands and contracts in a predetermined manner. The elastic member 95 has an insertion hole 96 through which the thermal conductor 90 is inserted, and is arranged so that the middle portion of the thermal conductor 90 is inserted into the insertion hole 96 to connect adjacent thermal conductors 90. By attaching the elastic member 95 to the outer surface 10a of the side of the first container 10, the thermal conductor 90 can be arranged on the outer surface 10a of the side of the first container 10.

The elastic member 95 is provided with a hook-and-loop fastener 97, which has a male hook-and-loop fastener 97a provided at one end 95a of the elastic member 95 and a female hook-and-loop fastener 97b provided at the other end 95b of the elastic member 95. By engaging the male hook-and-loop fastener 97a and the female hook-and-loop fastener 97b with each other, the elastic member 95 can be attached to the outer surface 10a of the side of the first container 10. The elastic member 95 can be made of rubber mesh.

In addition, in the ventilation device 4 of this modified example, the opening/closing section 81 may be opened and closed using a button B as shown in Figure 26, or may be opened and closed using a hook-and-loop fastener C as shown in Figure 27, or may be opened and closed using a hook-and-loop fastener.

Alternatively, the thermal conductor 90 can be the thermal conductor 90' shown in Figure 28, which is configured by providing multiple fins 94' inside a rectangular cylindrical body 91' forming the base. The thermal conductor 90' can include at least a metal, and the metal can be, for example, iron or copper.

The thermal conductor 90' is in contact with the flowing air, and one surface 92a' of the cylindrical body 91' forms a container contact portion 92a' that contacts the first container 10 side. This container contact portion 92a' allows the cooled temperature to be transferred from the container 10 side to the air side. Similar to the thermal conductor 90 described above, the container contact portion 92a' contacts the first container 10 side via a heat-dissipating and/or elastic material 93. Furthermore, the container contact portion 92a' contacts the first container 10 side via a thermoelectric element 94. The thermoelectric element 94 may be a Peltier element, and by passing an electric current through it, the first container 10 side can be heated and the thermal conductor 90 side can be cooled. The thermal conductor 90' has its middle portion inserted through the insertion hole 9 of the elastic member 95, and the elastic member 95 is arranged to connect adjacent thermal conductors 90. By attaching the elastic member 95 to the lateral outer surface 10a of the first container 10, the thermal conductor 90' can be provided on the lateral outer surface 10a of the first container 10.
