After joining, the edge joints are fused at high frequency to the iron core so that the inner and outer shells are firmly bonded to each other and the transverse bulkheads are formed on the inner lid of the lid to form the three side dishes and the bowls and soup bowls on the back Blocks the space between the rice and soup to prevent hot warmth from being transferred to the side dish bowl, and covers the top of the rice bowl to maintain the temperature of the hot rice and puts a container in which the lid of the separate object is sealed in the soup bowl. Lunch box for easy storage of soup

Description

Thermal Lunch Box {Lunch box for keeping warmth}

The present invention relates to a lunch box for heat insulation configured to have three side dish containers, which are usually used at the time of feeding, and a plate formed with rice bowls and soup bowls with lids and to keep warm.

So far, the plate used in the meal has been made by using a stainless steel plate or a plastic plate at the bottom to form three side dishes with a small area on the rear side and a large rice bowl and a soup bowl on the whole side. It can be used only when serving rice and soup directly at the table, and there is no lid on the plate, and it is not kept warm, so it is not possible to use rice and soup at different places by changing the time and space. There was a need to establish a cost and a large restaurant.

In the present invention, in order to improve such a problem, the lid and the body for thermal insulation are filled with the inner layer and the outer shell by inserting an insulation layer in the space between the inner and outer shells of the inner and outer shells to be inserted into the inner core and the outer shell After inserting and joining as the edge protrusion of fusion, the edge joining part is fused at high frequency to the iron core and the inner and outer shells are firmly bonded to each other, and the transverse bulkhead is formed on the endothelial of the lid. Block the space between the rice bowl and soup bowl to prevent the hot warmth of rice and soup bowls from being transferred to the side dish bowl, and cover the top of the rice bowl to maintain the temperature of the hot rice. According to the drawing, it is made so that the soup filled with the container is not spilled and it is convenient to put the soup. If you explain in detail as follows.

The bottom outer hooves of the lower body are inserted into the neck corner, and the upper surface of the lid is formed with a rectangular recessed end 12 (12) and a band groove 22 is formed in the middle of the edge partition wall, and the side dishes and the rear side of the rice bowl, across the rice bowl Filled by inserting the insulation layer (A) in the space between the lid endothelial 20 formed partition wall 23 and insert the core (C) to be inserted into the edge groove 21 of the lid endothelial 20 and the outer shell lid (10) is inserted into the edge protrusion (11), and then bonded to the core (C) by fusion bonding the edge coupling portion with a high frequency to form a heat insulating cap, and a band protrusion 42 is formed in the center of the edge and the normal shape to the rear side Three side dish bowls (1), (2) and (3) with small areas, and a bowl (4) and a bowl (5) with a large area toward the whole body endothelium (40) and the bottom corner of the hoof (32) Filled by inserting the insulation layer (B) in the space between the body shell 30 is formed Insert the iron core (C) to be inserted into the inside of the lid outer shell (30) and the edge protrusion 41 and the outer protrusion (41a) of the lid inner shell (40) to be inserted and coupled to iron core (C) It is made by fusion of the edge coupling portion at high frequency to form a body for keeping warm, and putting a cover 43 on the top of a bowl of heat keeping body, and putting a container 44 in which a lid 44a of a separate object is sealed in a soup bowl. Reference numeral 33 is a recess for the handle.

The present invention has a structure such as this, in which the lid and the body for thermal insulation are combined as the inner skin and the outer skin, and the insulation layers (A) and (B) are inserted into the spaces therebetween to fill the inner and outer edge grooves. (21), (31) is inserted into the core (C) to be inserted into the inner and outer edges of the outer shell (11), (41) and inserted into the joint after the edge joints were welded to the iron core at high frequency, so the inner and outer shell The edges to be joined are fused to become the same body, not only to strengthen the binding, but also to the inner and outer edges of the outer shell, the core is fitted in the core, which reinforces the edge strength of the lid and the body. When holding rice and soup, you can maintain the overall balance when holding a lunch box with load, and form a banding protrusion (42) in the middle of the edge of the body endothelial and 22) is formed, so that when the lid is kept on top of the body for insulation, the band protrusion is engaged with the band groove of the edge and the lid is securely covered without fluidity, and the transverse bulkhead 23 formed on the lid inner shell 20 is formed on the rear side. Three side dish bowls (1), (2) and (3) with small areas and rice bowls with soup and soup bowls by blocking the space between the large bowls (4) and soup bowls (5). This prevents the hot warmness of the bowl from falling into the side dish bowl and covers the top of the rice bowl with a lid 43 to maintain the temperature of the hot rice and puts a container 44 in which the lid 44a of a separate object is sealed in the soup bowl. It is convenient to contain soup by pouring soup into it, and it is convenient to hold soup, and the upper surface of the lid shell 10 has formed a rectangular recessed end 12, so the lunch box for upper insulation when the lunch box is loaded up and down Hooves (32) formed on the bottom of the body The loading state is maintained as it is inserted into this recessed end even when several pieces are stacked up and down.
