Description

[Detailed description of the invention] <Industrial field of application> This invention relates to a lunch box container, in which at least one chamber within the box lunch container is isolated from other rooms so that tea containers, etc. can be stored therein. .

<Problems to be solved by the prior art and the invention> Conventionally, bento boxes and tea sold at station kiosks, etc. have been sold separately, which has been cumbersome in terms of sales and handling after purchase, making it difficult for buyers. It was very inconvenient for people who had a lot of baggage or to buy a lot of bento boxes and tea.

Furthermore, if hot tea, soup, etc. are stored in a bento container, the side dishes stored in the adjacent area may be heated, which may lead to unfavorable conditions for the side dishes, and furthermore, the odor of the soup, etc. There was also a risk that the taste would be impaired if it was transferred to side dishes.

Therefore, the present invention is intended to solve the above-mentioned conventional disadvantages, and to provide a lunch container that is easy to manufacture and inexpensive.

<Means for Solving the Problems> The structure of this invention to achieve the above object includes a heat insulating partition that extends halfway down the depth of the main body of the lunch box container, which is formed from a foamed polystyrene resin sheet. In addition to providing a wall, a heat insulating partition wall having a height equal to the depth inside the container body is also integrally provided. There is a space on one side that bulges out from the bottom of the container body, and when the lid is covered, a partition wall with a height equal to the depth inside the container body separates the space from other storage chambers. It is characterized by forming a storage chamber for tea containers, etc., which is isolated not only from the target but also from the standpoint of heat transfer.

<Function> This device is constructed as described above, and has an insulating partition wall halfway down the depth of the main body of the bento box container, which is formed from a foamed polystyrene resin sheet. For example, cooked rice, side dishes, etc. stored in a storage chamber partitioned by a partition wall halfway down the depth of the main body can be easily eaten.

In addition, in addition to the heat-insulating partition wall that extends halfway into the container body, a heat-insulating partition wall with a height equal to the depth inside the container body is also provided to ensure better heat transfer than other storage compartments. Since there is a storage chamber for tea containers, etc., which is isolated from the target, it is possible to prevent the heat of tea, etc., or the odor of soup, stew, etc. stored in this storage chamber from moving to other storage chambers.

The heat insulating partition wall has a space on the outer side of the bottom of the container body and is formed to bulge out from the bottom of the container body, and together with the excellent heat insulating effect of the foamed polystyrene resin sheet, the outer side of the bottom of the container body This space can prevent heat from tea, etc. from transferring to other storage rooms.

The entire container body is integrally formed from a foamed polystyrene resin sheet by sheet forming such as vacuum forming or pressure forming, and the partition wall can be integrally formed at the same time as forming the container.

<Example> Next, an example of this invention will be illustrated below with reference to the drawings.

Reference numeral 10 denotes a container body for a lunch box, which is entirely formed from a foamed polystyrene resin sheet by a sheet forming method such as vacuum forming or pressure forming.

Reference numeral 13 denotes a storage chamber for cooked rice, and 14 denotes a storage chamber for prepared foods. A partition wall 15 between the two is provided halfway down the depth of the container body 10, so that the cooked rice and prepared foods can be easily eaten.

Reference numeral 17 denotes a heat insulating partition wall formed integrally with the container body 10, which has a height equal to the depth inside the container body 10, and has a space S on the outside of the bottom surface of the container body 10. A bulge is formed.

16 is a storage chamber for tea containers A, etc., and this storage chamber 16 for tea containers A, etc. is surrounded on all sides by the above-mentioned heat insulating partition wall 17. Therefore, when the storage chamber 16 for tea containers A, etc. is covered with the lid body 20 described later, it is configured as a storage chamber that is isolated from other storage chambers not only spatially but also thermally. become.
18 is a chopstick storage room, and 15' is a reinforced partition wall with one part raised.

In addition, in order to isolate the cooked rice storage chamber 13 and the side dish storage chamber 14, an inner lid (not shown) made of a foamed resin sheet may be attached to either of them.

A lid 20 is attached to the container body 10 and is made of a synthetic resin sheet such as a foamed resin sheet or a transparent or opaque non-foamed high-impact polystyrene sheet.

Note that the shape of the container main body 10 can be variously implemented; for example, it may be formed so that the tea container A can be stored horizontally, or it may be implemented by providing more storage chambers for side dishes. moreover,
The container body 10 can also be formed from a foamed polystyrene resin sheet whose surface is laminated.

On the other hand, in the isolated storage room 16 for tea containers, etc.
Containers containing soup, stew, coffee, tea, etc. may be stored in the storage chamber, and in either case, the depth of the container body 10 is used to transfer the heat and odor of the soup to the cooked rice storage chamber 13 or the side dish storage chamber 14. This can be effectively prevented by the heat insulating partition wall 17 provided at the same distance.

<Effects of the invention> This invention is constructed as described above, and is made by providing a heat insulating partition wall midway in the depth of the main body of the lunch box container made of expanded polystyrene resin sheet. For example, cooked rice and side dishes stored in the storage chamber partitioned by the partition wall halfway down the depth are convenient and easy to eat.

In addition to the above-mentioned heat-insulating partition wall extending halfway into the main body, a heat-insulating partition wall having a height equal to the depth inside the container body is integrally provided, and the lid body is covered with this heat-insulating partition wall. When the lid is closed, a storage chamber for tea containers and the like is isolated from other storage chambers not only spatially but also thermally. Therefore, by using a heat insulating partition wall with a height equal to the depth inside the main body, even when storing tea containers etc. in a heated state, it is possible to prevent other storage compartments from being affected. The container and the like can be stored together, making it convenient for sales and other handling, and also convenient for the purchaser when he or she has a lot of baggage or when purchasing a large amount of boxed lunches and tea.

In particular, the heat-insulating partition wall, which has a height equal to the depth inside the container body, has a space on the outside of the bottom of the container body and bulges out from the bottom of the container body. Combined with the function, it is possible to effectively prevent the heat of tea etc. from transferring to other storage compartments, avoid the inconvenience of heating up side dishes etc., and also make it possible to store tea containers etc. in a good heat-retaining state. It also becomes.

In addition, the entire container body is integrally molded from a foamed polystyrene resin sheet by vacuum forming, pressure forming, etc., making it easy to manufacture the insulating partition walls and at low cost. .

In addition, when storing soups, stews, etc., the same effects as described above are achieved, and it is also possible to prevent odor from being transferred to side dishes, etc., thereby avoiding deterioration in the taste of side dishes, etc. due to odor.

As described above, according to this invention, it is possible to store tea containers etc. in an integrated manner, and it can be used as a lunch box container that can simultaneously store hot items and items that are better kept at room temperature or cold temperature. This means that various excellent effects such as those described above can be exhibited that are not available in other systems.
