Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below. The structures, proportions, and dimensions shown in the drawings and described in the specification are only for the purpose of understanding and reading the present disclosure, and are not intended to limit the scope of the present disclosure, which is defined in the claims, and therefore, the present disclosure is not limited to the essential meanings of the technology, and any modifications of the structures, changes of the proportions, or adjustments of the dimensions, should be within the scope of the disclosure without affecting the efficacy and attainment of the same. In addition, the terms such as "upper", "lower", "left", "right" and "middle" used in the present specification are used for clarity of description, and are not used to limit the implementable scope, and the changes or adjustments of the relative relationship thereof can be considered as the implementable scope of the present invention without substantial technical changes.

Referring to fig. 1, a separable self-heating lunch box comprises a separated bowl bottom 1 and a bowl body 2, wherein the bowl body 2 is connected to the bowl bottom 1 to seal and cover the bowl bottom 1.

Referring to fig. 2 and 3, a heating bag 11 is connected to the bottom of the bowl bottom 1. A heating envelope film 12 is also arranged in the bowl bottom 1. The heating envelope film 12 is used for sealing the bowl mouth of the bowl bottom 1 and preventing water from entering the bowl bottom 1 when not in use. When the bowl body 2 is required to be used, the bowl body 2 can be taken down from the bowl bottom 1, the heating packaging film 12 is uncovered, water is added into the bowl bottom 1, the bowl body 2 is covered again, and the heating packaging film 11 reacts to generate steam to heat food. Because the heating bag 11 is welded on the bottom surface of the bowl bottom 1 by the ultrasonic welding technology, the heating bag 11 can not float when reacting with water and always stays in the water, so that substances in the heating bag 11 can completely react with the water, more generated heat is ensured, and the inner container 33 can be effectively heated.

Referring to fig. 3 to 6, the bowl body 2 includes an outer side 21 and an inner container 22, and the inner container 22 is located at the center of the outer side 21 and forms an inner cavity 23. A plurality of raised strip-shaped ribs 24 are also provided circumferentially on the outer side 21. The outer side 21 and the inner container 22 are integrally formed. A sealing film 3 for sealing the inner container 22 is connected to the upper part of the outer side edge 21. The inner chamber 23 of inner bag 22 is used for placing food, after holding food, seals inner bag 22 through seal membrane 3, uncovers seal membrane 3 after the heating is accomplished and can eat food, simple structure, and convenient operation need not loaded down with trivial details bale breaking reinforced. The strip-shaped convex ribs 25 support the bowl body 2, improve the structural strength of the bowl body 2 and avoid deformation of the bowl body 2 due to heating. With the bowl body 2 of outside limit 21 and inner bag 22 constitution, the bowl body 2 both can be used for holding food, can regard as the lid to seal at the bottom of the bowl again, has reduced the raw materials that preparation cutlery box needs, more can realize at the bottom of the bowl and the separation design of the bowl body 2, can easily take off the bowl body 2, is scalded by steam when avoiding edible food. The prefabricated sealing film 3 is matched with a high-barrier material, food is placed into the bowl in advance, the delicate flavor of the food is locked, the operation steps are reduced, and excessive packaging can be avoided.

The lower end of the outer side edge 21 is provided with a sealing edge 25 which is sealed and buckled on the bowl mouth of the bowl bottom 1. The sealing edge is also provided with a handle 26 extending outwards from the bowl opening, and the handle 26 is symmetrically arranged. The bowl body 2 and the bowl bottom 1 can be connected through the sealing edge 25, the bowl bottom 1 and the bowl body 2 are separated through the lifting handle 26 when the bowl bottom 1 needs to be taken down, so that the bowl bottom 1 can be taken down quickly, and the bowl bottom 1 and the bowl body 2 can be connected and separated quickly. After the bowl body 2 is separated, the bowl body 2 can be stably placed on a table top by taking the sealing edge as a support.

A gap is arranged between the outer wall of the inner container 22 and the inner wall of the outer side edge 21 as well as the inner wall of the bowl bottom 1, a heating cavity 27 is formed among the outer wall, the inner wall and the inner wall, and an air exhaust structure 28 is arranged above the outer side edge 21. The steam generated by the heating bag 11 is filled with the heating strong and is exhausted from the exhaust structure 28 after passing through the outer wall of the inner container 22 from bottom to top. The bottom surface of the inner container 22 is a wave-shaped structure which firstly sinks downwards and then protrudes upwards from the outer periphery to the center. The heating bag 11 is positioned right below the bottom of the inner container 22 and is arranged with a gap from the bottom of the inner container 22. After heating package 11 meets water and produces steam, steam flows from bottom to top and fills heating cavity 27, and heating cavity 27 covers whole inner container 22, and therefore, steam can fully contact inner container 22. Because the wave structure of the bottom surface of the inner container 22, the contact area between the bottom surface of the inner container 22 and steam can be increased, and the steam can be guided, so that the steam can flow upwards along the outer wall of the inner container, the contact area between the inner container 22 and the steam is larger, the heat exchange time is prolonged, and the heating effect of internal food is better. Furthermore, the inner container 22 and the outer side 21 are arranged at intervals, and the gap between the inner container and the outer side is gradually reduced from bottom to top, the gap structure provides guidance for steam flow, steam flowing from bottom to top is discharged from the exhaust structure 28 after sufficient heat exchange, the steam is discharged in a concentrated manner, and the heat exchange time of the steam and the inner container 22 is prolonged.

Referring to fig. 7, the upper surface of the outer side 21 has a step structure 29, and the exhaust structure 28 is disposed on the step structure 29. The venting structure 28 is located below the sealing membrane 3. The exhaust structure 28 includes a plurality of exhaust holes 281 uniformly arranged at intervals, and the exhaust holes 281 are located on the upper surface of the step structure 29. Cut parallel arrangement's exhaust hole 281 through setting up a plurality of intervals, satisfy exhaust effect, avoid inside steam gathering can't discharge and lead to the bowl body 2 inflation and take place danger simultaneously, guarantee steam and effectively heat inner bag 22 when satisfying steam exhaust gas flow. Steam is shielded and guided by the step structure 29 and the sealing film 3, so that the steam can be decelerated and cooled and is obliquely discharged from the side part, and the steam is prevented from being directly upwards discharged to cause the scald of a user by contacting the steam.

Different from the prior art, the split self-heating lunch box can simplify the structure of the lunch box, prevent steam from contacting with food in the heating process, and has simple structure and convenient use.

The present invention and its embodiments have been described above schematically, without limitation, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching, without departing from the spirit of the invention, the person skilled in the art shall not inventively design the similar structural modes and embodiments to the technical solution, but shall fall within the scope of the invention.
