[Detailed description of the invention] (Field of industrial application) This invention relates to a storage structure for a thermal lunch box, and more specifically, for a water bottle.

(Prior Art) Conventionally, this type of thermal lunch box having a structure for storing a water bottle is simply shown in, for example, Japanese Utility Model Application Publication No. 167082/1982 filed by the applicant of the present application. This water bottle is simply placed in the empty space below the inner container (rice bowl) of the insulated lunch box.

(Problem to be solved by the invention) However, according to the above-mentioned conventional example, the water bottle is put in and taken out independently from the empty space of the inner case.
There was an inconvenience that it could not be taken out and put in together with the inner container. In addition, if the stopper of the water bottle is loosened due to forgetting to close it, etc., there is a problem in that the liquid inside the bottle leaks into the chamber.

This invention provides a solution to the above problems.

(Means for solving the problem) This invention, as a means to solve the above problem, includes a main body provided with a heat insulator such as a vacuum double bottle, a lid body for opening and closing the upper opening of this main body, In a heat-retaining lunch box comprising an inner container such as a vegetable container, a rice bowl, a soup container, etc. that can be stored in and out of the main body, a storage body having a closed space is removably provided in the inner container, and the storage body is removably provided. It is characterized by storing a water bottle in a closed space of the body so that it can be taken out and put in freely.

(Example) A first example of this invention will be described below based on FIGS. 1 and 2.

Reference numeral 1 denotes a main body of a heat-retaining lunch box, and between an outer case 3 and an inner case 4 of the main body 1, a heat insulating body 5 such as a double vacuum bottle is installed as shown in the figure, or although not shown in the figure, It is filled with a heat insulating material such as urethane foam to the required thickness to have a heat insulating effect. Alternatively, there may be a heat insulating body that also serves as the outer case 3 and the inner case 4, such as a known stainless steel vacuum double bottle. Reference numeral 2 denotes a lid that closes the upper opening of the thermal lunch box main body 1, and an inner container 6 such as a rice bowl is stored in the empty space formed by the lid 2 and the main body 1 so as to be freely put in and taken out. ing. In the figure, the inner container 6 includes a soup container 7 and a rice bowl 8 housed in an inner case 4 having a heat-insulating effect, and a vegetable container 9 housed between the shoulder 4a of the inner case 4 and the lid 2. These are stacked one after another and stored.

c. A heat insulating material storage cylinder 21a is hung down near the outer periphery, and the heat insulating material 21 is stored in this storage cylinder 21a, and the bottom plate 21 is
c, and a male thread 21b is formed on the outer circumferential side of the heat insulating material storage cylinder 21a.
A gasket 21d is fitted between the outer circumferential edge of the bottom plate 9c of the vegetable container 9, and when the vegetable container 9 is stored in the inner case 4, the heat insulating material storage tube 21
a fits into the upper opening of the inner case 4 and serves as a cover for the upper opening, and at the same time, the gasket 21d prevents the hot air inside the inner case 4 from dissipating to the outside. . On the other hand, a cylindrical storage body 10 having a female thread 10a inside the upper part and a closed space 11 is formed by screwing the female thread 10a and the male thread 21b of the heat insulating material storage cylinder 21a into a vegetable container 9. The water bottle 12 is removably connected to the closed space 11, and the water bottle 12 is stored in the closed space 11 so as to be freely put in and taken out. In this case, the holding part 1 that stores and holds the water bottle 12
3a also serves as the bottom plate of the storage body 10. Therefore, when storing the water bottle 12 in the closed space 11, the storage body 10 is removed from the heat insulating material storage cylinder 21a, and with the water bottle 12 placed and stored in the storage body 10, the male screw of the heat insulating material storage cylinder 21a is removed. If the female screw 10a of the storage body 10 is screwed into 21b, the storage body 10
is integrally connected to the heat insulating material storage cylinder 21a (that is, the vegetable container 9). In this state, if you lift the vegetable container 9 from the inner case 4, the water bottle 12 will be removed from the vegetable container 9.
It is taken out from the inner case 4 together with.

The shape of the water bottle 12 can be designed in various ways taking into consideration the shapes of the inner case 4, vegetable container 9, etc., but in this embodiment, since the inner case 4 and the container 10 have a circular cross section, As shown in the second figure, the bottom and shoulder (excluding the neck) of the disc-shaped main body of the water bottle 12 are cut parallel to each other, and the cap 12a is screwed onto the neck protruding from the center of the shoulder. A gasket 12c is fitted inside the cap 12a to watertightly seal the liquid inside the water bottle, and when the cap 12a is horizontal and the main body of the water bottle is placed horizontally, the closed space 11
It is a side-loading type that is stored and held inside from below.

A soup container 7 is stored immediately below the closed space 11 of the water bottle 12, and a rice bowl 8 is stored below the soup container 7. Juice container body 7a of the juice container 7
On the outer periphery of the upper part, an outer cover 7c having a heat insulating material 22 therein is screwed together via an inner cover 7b, and an air hole 40 formed in the center of the inner cover 7b and an outer cover 7c that closes the air hole 40. Both the protrusion 41 vertically disposed on the bottom prevent the inside of the juice container main body 7a from becoming negative pressure. In other words, with this negative pressure prevention member,
The inner cover 7b may be strongly adsorbed to the juice container body 7a, making it difficult to remove the inner cover 7b, or if the inner cover 7b is removed with force, it will suddenly come off, causing the liquid content to wave, scattering to the outside, and leaking. This is to eliminate the inconvenience.

A heat insulating material 2 provided at the bottom of the vegetable container 9
In addition to 1, there is also a heat insulating material 22 inside the outer lid 7c of the soup container 7.
In addition, since the rice bowl 8 is stored at the bottom of the inner case 4, the heat retention effect of the rice bowl 8 is sufficient. I didn't set it up on purpose. In this way, since there is no need to use a heat insulating material in the rice bowl 8, the rice bowl 8 has the advantage of having a large storage capacity for rice.
The lid 8b of the rice bowl is also formed into a simple plate shape,
A concave portion 7d is formed in the bottom plate of the juice container 7 to correspond to the knob 8d formed to protrude upward, and both 8d,
The engagement of 7d prevents the soup container 7 and the rice bowl 8 from shaking, and also makes it easy to take out the rice bowl 8.

Reference numeral 23 designates a locking member that detachably engages with an engagement hole 25 of a rising piece 24 erected on the upper surface of the shoulder portion 4a of the inner case 4 to lock the lid 2 to the outer case 3. The locking member 23 has a substantially S-shaped cross section with an outwardly bent upper portion and an inwardly bent lower portion, and has an outwardly directed protrusion 26 formed at its lower end. Recesses 2b, 2b are formed at opposing positions on the outer wall of the lid 2, and the recesses 2b are biased by a spring 27 so that the upper outward bent portion of the locking member 23 is flush with the outer surface of the lid 2. and the protrusion 2 of the lower inwardly bent portion of the locking member 23.
