As shown in the transverse sectional view of FIG. 3, the heat insulating case 20 is partitioned into four small chambers 24 (see FIG. 1) by partitioning sections 23 extending in the vertical direction, and each of these small chambers 24 is divided. The liquid containers 30 are housed in the rooms 24, respectively.

By vertically partitioning in this manner, the liquid container 3
Even if 0 is stored, the heat insulating case 20 is easily bent at the partition 23 as a boundary, and when the backpack is carried on the back, it fits perfectly against the body and is excellent in usability, which is preferable.

The liquid container 30 is, as shown in FIG.
Although the size is stored in each of the small rooms 24,
The inside is vertically divided into four equal parts by a bottom plate 32 having a communication hole 31, and one section has a size of, for example, about 200 ml.

This liquid container 30 is provided with capped outlets 33 at the top and bottom to facilitate not only pouring but also taking out. An extension hose (not shown) can be detachably attached to the lower outlet 33. It is provided, and if necessary, the user can inhale it and drink the beverage while carrying the rucksack on his back. At the time of this suction, it is necessary to remove or loosen the cap of the upper outlet 33.

In particular, in this embodiment, since the heat insulating case 20 of the rucksack serves as a heating and cooling source for outdoor activities such as hiking and mountain climbing, the drink in the liquid container 30 is A heated beverage serving as a heating source is injected, and in the summer or the like, a pre-injected beverage frozen as a cooling source is frozen in a freezer or the like.

The heat insulating case 20 is provided with a heat radiating portion 25 on the back support surface of the heat insulating case 20 so that the heat from the liquid container 30 housed therein can be satisfactorily transferred to the user. In the illustrated example, the heat dissipation portion 25 is formed by forming a plurality of ventilation holes O on the back contact surface side of the heat insulating case 20.

With this arrangement, the user carries the rucksack on his back, so that the cool air or the warm air from the liquid container 30 directly contacts the user's back, and the outdoor activities can be comfortably performed.

The vent hole O is preferably formed so as to correspond to each liquid container 30, but the opening area may be appropriately selected in consideration of the heating and cooling time.

Next, the operation will be described. For example, when outdoor activities are performed in the summer or the like, since the beverage in the liquid container 30 is used as a cooling source, the liquid container 30 taken out in advance is used.
The beverage is poured into the inside of the container, which is put in a freezer to be frozen and then stored in the heat insulating case 20.

When the backpack with such a liquid container 30 set is carried on the back, the frozen beverage in the liquid container 30 is mainly due to the effect of the body temperature of the user (although there is an effect of the ambient outside temperature). Is thawed, and the cold air of the frozen beverage is transmitted to the user's back through the heat dissipation part 25.

Next, when the outdoor activity is performed in the winter season or the like, the beverage in the liquid container 30 is used as a heating source. Therefore, the heated beverage is poured into the liquid container 30 taken out in advance, It is stored in the heat insulating case 20.

When the backpack with such a liquid container 30 set is carried on the back, a large amount of heat is transferred from the heat radiating portion 25 of the heat insulating case 20 to the user's back, and outdoor activities are started in a comfortable state. be able to. In particular, since the body is not warm at the beginning of the outdoor activity, if the user carries the rucksack on his back, the user receives the heat from the heat radiating unit 25 on his back and the entire body is warmed, which facilitates the outdoor activity. Injuries can also be prevented.

If the user becomes thirsty while doing this, the liquid container 30 is taken out, or the drink in the liquid container 30 is drunk through the extension hose attached to the outlet 33. Can thirst.

The present invention is not limited to the above-mentioned embodiments, but can be variously modified and used within the scope of the claims.

For example, in the above-described embodiment, the heat dissipation part 2
As shown in FIG. 5, a plurality of ventilation holes O are simply formed on the back support surface side of the heat insulating case 20, but in some cases, as shown in FIG. 5, the back support surface of the heat insulating case 20 is laterally broken, A large horizontally long ventilation hole O or a horizontally long ventilation hole O having a length corresponding to each of the plurality of individual liquid containers 30 is formed, and a plate 2 having a shutter door is formed so as to cover these ventilation holes O.

According to the embodiment as described above, for example, when outdoor activities are performed in the summer or the like, the liquid container 30 in which the drink is poured is put in the freezer and frozen in the heat insulating case 20 as described above. Store.

Initially, the backpack is carried on the back with the heat radiating portion 25 closed. In this state, the body temperature of the user is not transmitted to the liquid container 30 and the liquid container 3
Thawing of frozen beverages within 0 is very slow.

When outdoor activities are carried out in this state for a while, the body temperature rises and it becomes hot, so keep the rucksack on the back or lower the rucksack,
The plate 26 of the heat dissipation part 25 is opened slightly. Thereby, the cold air of the frozen beverage is transmitted to the user's back through the heat radiating portion 25, and a cool feeling is obtained.

When it becomes hot during further activity, the opening of the heat radiating portion 25 is further opened. As a result, the amount of transmitted cool air is increased, a greater cooling feeling is obtained, and the thawing speed of the frozen beverage in the liquid container 30 is increased.

If the user becomes thirsty while doing this, the liquid container 30 is taken out or the thawed drink in the liquid container 30 is taken out through the extension hose attached to the outlet 33. You can drink and quench your thirst.

In this case, initially, the heat radiating portion 25 of the heat insulating case 20 carries the rucksack on its back in an opened state, which is opposite to that in the cooling operation. This allows the user to transfer a large amount of heat from the back and start outdoor activities in a comfortable state.

When outdoor activities are performed in this state for a while, the body temperature rises and the temperature becomes hot. Therefore, the backpack is lowered while the backpack is carried on the back, and the opening of the plate 26 is slightly closed. This reduces the amount of heat transferred from the liquid container 30 to the back through the heat dissipation portion 25.

When it becomes hot during further activity, the plate 26 is further closed to suppress heat transfer,
You can carry out outdoor activities without feeling uncomfortable.

If the user becomes thirsty while doing this, the liquid container 30 is taken out or the drink in the liquid container 30 is drunk through the extension hose attached to the outlet 33. Can thirst.

In the above embodiment, the heat insulating case 2 is used.
The inside of 0 is divided into four small chambers 24, and the liquid containers 30 as shown in FIG. 4 are individually stored in each small chamber 24. However, not only this but also the number of partitioning portions 23 is changed. Alternatively, the partition section 23 itself may be appropriately moved. Further, when the entire room is made into one room without being divided into the small rooms 24, as shown in FIG.
An integrated unit of 0 may be housed in the heat insulating case 20.

Furthermore, the present invention can be used while traveling in a vehicle. For example, as shown in FIG. 7, a pair of heat insulating cases 20 are connected by a connecting string 27, and
As shown in, the back rest portion 28 of the seat S of the vehicle can be used by being hung so as to be distributed. Even in this case, it is possible to obtain the same cool breeze as described above. However, the case of providing the backrest portion 28 of the seat S, the safe driving or driving position since it is preferable that the natural state, provided a recess in the backrest portion 28 as shown in FIG. 8, in this The heat insulating case 20 is fitted in the.

The present invention can also be used by hanging it on the back of a chair used in the office or at home.
Also in this case, as shown in FIG. 9, it is preferable to provide a recess in the back support so that the heat insulating case 20 can be fitted therein.
