Abstract

Disclosed is a lunch box small container that can reliably store a main meal and a side meal in a lunch box, and can warm the side meal deliciously even when heated by a microwave oven.
A small container 2 to be accommodated in a lunch box, wherein an upper end surface of a cup-shaped container main body 3 and a peripheral end of a lid body 4 that covers the container main body 3 are opposed to the upper end surface of the container main body 3. A plurality of small protrusions 5 are provided on the lower surface of the portion along the circumferential direction. By providing the small protrusions 5, a gap is formed even when the lid body 4 is covered with the container body 3, thereby forming the container body. The inside 3 can ensure air permeability to the outside, and even if heated in a microwave oven, the inside food does not burst and collapse, and the lid 4 can be easily removed.

Description

  The present invention relates to a small container stored in a lunch box.

  In the lunch box for storing rice as a staple food and side dish as a side dish, the inside of the lunch box is kept in order to prevent the staple food and supplementary food from mixing together, so that the flavors may not soak in each other, and the smell may not move. It has been conventionally performed to divide the food into a plurality of parts or to put a small container for storing a side meal separately.

  For example, the following proposals are made.

Japanese Utility Model Publication No. 2-48550 Japanese Utility Model Publication No. 2-79821

  These devices have a certain degree of effect in that the main meal and the side meal can be stored separately in one lunch box. However, these proposals have many constituent members and remain unsatisfactory in that it takes time to clean up after use. Moreover, when trying to warm the whole lunch box with a microwave oven, especially in a small container for storing a side meal, the side food may burst due to heat and collapse.

  Traditionally, if you only need to store staple food and side food separately, for example, water-resistant paper small cup containers and aluminum foil small cup containers are used, but the smell and taste are It is impossible to avoid the phenomenon of breakup of side dishes due to mixing or heating. In the first place, aluminum foil cannot be used in a microwave oven.

  Small containers with a lid made of a synthetic resin such as silicon may be used, but there are also disadvantages such as the side food being ruptured by heating or the lid of the small container being difficult to open by heating.

  Therefore, the present invention is a lunch box small container developed to eliminate the above-mentioned disadvantages, inconveniences and dissatisfactions of the above-mentioned prior art, and the staple food and the side meal can be reliably separated and stored in the lunch box. The purpose is to allow the side meal to be warmed even if heated by heating.

  In order to solve the above-mentioned problems, a small container for a lunch box according to the present invention is a small container to be stored in a lunch box, the container having the upper end surface of a cup-shaped container main body and a lid that covers the container main body described above. A plurality of small protrusions are provided along the circumferential direction on any one of the lower surfaces of the peripheral end portions facing the upper end surface of the main body.

  Since the small container to be stored in the lunch box has the above-described configuration, when the container body is covered with the lid, the peripheral container is disposed between the upper end surface of the container body and the lower surface of the peripheral end portion of the lid body facing the container body. A slight gap is generated by the plurality of small protrusions provided along the direction, and air permeability between the inside and the outside is ensured.

  Therefore, even if the side food in the small container heated together with the lunch box in the microwave oven is warmed and hot air is generated, the hot air will not be released to the outside through the above gap, so the internal side food Does not burst and collapse, and can maintain a delicious appearance when cooking.

  In addition, when the lid is closed and the upper end surface of the container body and the lower surface of the peripheral end of the lid are in contact with each other, the steam from heating is between the upper end surface and the lower surface of the peripheral end of the lid. However, if a small protrusion is provided to form a slight gap as in the present invention, it will not be in close contact or will be in a negative pressure state. Therefore, the lid can be easily removed.

  That is, if a small container like the present invention is heated and the inside becomes a negative pressure state, there is even a risk of burns taking time to open the heated lid with the fingertip, The present invention has many excellent effects such as no such inconvenience.

It is a perspective view of the state where the lid of the present invention was opened. It is sectional drawing of the state which closed the cover body of this invention. It is an expanded sectional view of the small protrusion part of FIG. It is a perspective view of the state which has arranged the small container of the present invention in the lunch box.

  The small container 2 accommodated in the lunch box 1 includes any one of the upper end surface of the cup-shaped container main body 3 and the lower surface of the peripheral end portion of the lid body 4 covering the container main body 3 facing the upper end surface of the container main body 3. In addition, a plurality of small protrusions 5 are provided along the circumferential direction.

  The lunch box 1 is made of synthetic resin and is a wooden container. As shown in FIG. 4, the lunch box 1 is filled with rice serving as a staple food and side dish serving as a side dish. Place.

The small container 2 is formed of a hard resin having excellent heat resistance, for example, a polypropylene resin, and the lid 4 is put on the upper end of the cup-shaped container body 3.

  The lid 4 has a configuration in which a short cylindrical peripheral wall 7 is suspended from the lower surface of a top plate 6 having a size that completely covers the upper end of the container body 3, and the peripheral wall 7 is loosely fitted to the upper end of the container main body 3. Accordingly, a slight gap S1 is formed between the outer peripheral surface of the peripheral wall 7 and the inner peripheral surface of the upper end portion of the container body 3.

Further, as described above, the top plate 6 is sized to completely cover the upper end of the container body 3 and the peripheral wall 7 is large enough to be loosely fitted to the upper end portion of the container main body 3. Between the outer periphery, a flange 8 mounted on the upper end of the container body 3 will be formed, and a plurality of small protrusions 5 are provided along the circumferential direction at an appropriate interval on the lower surface of the flange 8. A gap S2 is formed between the upper end surface of the container body 3 and the flange 8 surface.

  That is, even if the lid 4 is put on the container main body 3, the inside of the container main body 3 can be secured to the outside by the gap S1 and the gap S2. Therefore, as long as this air permeability is obtained, the small protrusion 5 may be the lower surface of the flange 8 or the upper end surface of the container body 3. And although the surrounding wall 7 is for preventing the position shift of the cover body 4 when covered, if the surrounding wall 7 does not exist, air permeability will further increase.

  Although the small container 2 in the illustrated embodiment has a simple pot lid shape, for example, a chrysanthemum shape, a cherry blossom shape, a heart shape, or the like is appropriately selected in consideration of the interestingness and the gorgeousness of the shape.
