Description

Technical Field

[0001] This utility model belongs to the field of lunch box technology, specifically relating to a four-component assembled lunch box. Background Technology

[0002] Currently, existing lunch boxes generally consist of a box body, a top lid, and an inner tray. The inner tray is placed inside the box body, and the top lid is used to seal the opening on the box body. This type of lunch box generally has a problem: the inner tray is placed inside the box body without any limiting structure to restrain it. During packaging and transportation, the inner tray will shake, causing soup or food to spill out, affecting the consumer's dining experience. In view of this, this solution was developed. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a four-component assembled lunch box, in which the three inner trays and the single inner tray will not move around in the receiving slot.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a four-part assembled lunch box, including a bottom box, a top cover, a three-compartment inner tray box, and a single-compartment inner tray box. The bottom box has a receiving groove, which includes a bottom mounting part and a limiting part. The limiting part is located above the bottom mounting part. A first limiting ring platform extending outward is formed at the opening of the receiving groove. An outwardly extending plate is formed at the outer edge of the upper opening of the three-compartment inner tray box and the single-compartment inner tray box. The plate on the three-compartment inner tray box and the single-compartment inner tray box are respectively adapted to the first limiting ring platform. The inner circumferential surface of the limiting part is adapted to the outer circumferential surface of the three-compartment inner tray box and the single-compartment inner tray box. The top cover is used to seal the opening of the receiving groove and connect to the bottom box.

[0005] Furthermore, a first protrusion is formed at the middle of any two corresponding sides of the first limiting ring platform. The first protrusion divides the first limiting ring platform into a first limiting area and a second limiting area. The first limiting area and the second limiting area are respectively adapted to the mounting plates on the three-compartment inner tray box and the single-compartment inner tray box.

[0006] Furthermore, a downwardly extending pad is formed at the outer edge of the upper opening of the three-compartment inner tray and the single-compartment inner tray, and the pad is connected to the lower end of the pad and extends outward.

[0007] Furthermore, a limiting groove is formed on the lower surface of the top cover.

[0008] Furthermore, a second limiting ring platform extending outward is formed at the opening of the limiting groove, and the mounting plates on the three-compartment inner tray and the single-compartment inner tray are respectively adapted to the second limiting ring platform.

[0009] Furthermore, a second protrusion is formed at the middle of any two corresponding sides of the second limiting ring platform. The second protrusion divides the second limiting ring platform into a third limiting area and a fourth limiting area. The third limiting area and the fourth limiting area are respectively adapted to the mounting plates on the three-compartment inner tray box and the single-compartment inner tray box.

[0010] Furthermore, the bottom box and the top cover are connected by a snap-fit ​​mechanism.

[0011] Furthermore, a first connecting plate extending outward is formed at the upper outer edge of the bottom box, and a second connecting plate extending outward is formed at the lower outer edge of the top cover. An annular protrusion or an annular groove is formed on the first connecting plate, and an annular groove or an annular protrusion is formed on the second connecting plate. The annular protrusion is deformed and inserted into the annular groove.

[0012] Furthermore, a first easy-open plate is formed on either side of the first connecting plate, and a second easy-open plate is formed on either side of the second connecting plate, with the first and second easy-open plates corresponding to each other vertically.

[0013] Furthermore, a first protrusion is formed on the upper surface of the first easy-open plate, and a second protrusion is formed on the lower surface of the second easy-open plate, with the first and second protrusions corresponding to and fitting together.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This invention provides a first limiting ring at the top opening of the bottom box, which is compatible with the mounting plates on the three-compartment inner tray and the single-compartment inner tray. This provides a first limiting effect when the three-compartment inner tray and the single-compartment inner tray are placed in the receiving slot. Then, a limiting part is provided on the receiving slot that is compatible with and fits the outer circumference of the three-compartment inner tray and the single-compartment inner tray, thus achieving a second limiting effect when the three-compartment inner tray and the single-compartment inner tray are placed in the receiving slot. Through this double limiting method, it is ensured that the three-compartment inner tray and the single-compartment inner tray will not shake during transportation. Attached Figure Description

[0017] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0018] like Figures 1-4 As shown, this embodiment provides a four-component assembled lunch box, including a bottom box 1, a top cover 2, a three-compartment inner tray box 3, and a single-compartment inner tray box 4.

[0019] The bottom box 1 has a receiving groove 11, which includes a bottom mounting part 12 and a limiting part 13. The limiting part 13 is located above the bottom mounting part 12. A first limiting ring platform 14 extending outward is formed at the opening of the receiving groove 11. A first protrusion 15 is formed at the middle of any two corresponding sides of the first limiting ring platform 14. The first protrusion 15 divides the first limiting ring platform 14 into a first limiting area and a second limiting area.

[0020] The upper openings of the three-compartment inner tray 3 and the single-compartment inner tray 4 are formed with outwardly extending mounting plates 51. Specifically, the upper openings of the three-compartment inner tray 3 and the single-compartment inner tray 4 are formed with downwardly extending pads 5, and the mounting plates 51 are connected to the lower end of the pads 5 and extend outward. The mounting plates 51 on the three-compartment inner tray 3 and the single-compartment inner tray 4 are respectively adapted to the first limiting ring platform 14. By placing the mounting plates 51 on the first limiting ring platform 14 in the first limiting area and the second limiting area, the three-compartment inner tray 3 and the single-compartment inner tray 4 are positioned once.

[0021] The outer circumferential surfaces of the three-compartment inner tray 3 and the single-compartment inner tray 4 are adapted and fitted to the inner circumferential surface of the limiting part 13. The setting of the limiting part 13 realizes the secondary limiting of the three-compartment inner tray 3 and the single-compartment inner tray 4, and avoids the three-compartment inner tray 3 and the single-compartment inner tray 4 from shaking during transportation.

[0022] The reason why the three-compartment inner tray 3 and the single-compartment inner tray 4 have downward-extending raised plates 5 at the outer edge of the upper opening is to create a height difference between the mounting plate 51 and the upper opening of the three-compartment inner tray 3 and the single-compartment inner tray 4. This arrangement makes it easier for consumers to take out the three-compartment inner tray 3 and the single-compartment inner tray 4 after opening the top cover 2.

[0023] A limiting groove 21 is formed on the lower surface of the top cover 2. A second limiting ring platform 22 extending outward is formed at the opening of the limiting groove 21. The mounting plates 51 on the three-compartment inner tray 3 and the single-compartment inner tray 4 are respectively adapted to the second limiting ring platform 22. A second protrusion 23 is formed in the middle of any corresponding two sides of the second limiting ring platform 22. The second protrusion 23 divides the second limiting ring platform 22 into a third limiting area and a fourth limiting area. The third limiting area and the fourth limiting area are respectively adapted to the mounting plates 51 on the three-compartment inner tray 3 and the single-compartment inner tray 4.

[0024] The limiting groove 21 and the third and fourth limiting areas separated by the second limiting ring platform 22 are provided on the top cover 2 so that when the consumer takes out the three-compartment inner tray 3 and the single-compartment inner tray 4, the top cover 2 can be flipped over and the three-compartment inner tray 3 and the single-compartment inner tray 4 placed in the third and fourth limiting areas, so that the food box takes up less space during use and improves the user's dining experience.

[0025] The bottom box 1 and the top cover 2 are connected by a snap-fit. A first connecting plate 16 extending outward is formed at the upper outer edge of the bottom box 1, and a second connecting plate 24 extending outward is formed at the lower outer edge of the top cover 2. An annular protrusion 161 is formed on the first connecting plate 16, and an annular groove 241 is formed on the second connecting plate 24. The annular protrusion 161 is inserted into the annular groove 241 by deformation. A first easy-open plate 162 is formed on either side of the first connecting plate 16, and a second easy-open plate 242 is formed on either side of the second connecting plate 24. The first easy-open plate 162 and the second easy-open plate 242 are vertically aligned. A first protrusion 163 is formed on the upper surface of the first easy-open plate 162, and a second protrusion 243 is formed on the lower surface of the second easy-open plate 242. The first protrusion 163 and the second protrusion 243 are aligned and fit together.

[0026] When the top cover 2 and the bottom box 1 are closed, the presence of the first protrusion 163 and the second protrusion 243 creates a gap between the first easy-open plate 162 and the second easy-open plate 242, allowing consumers to easily pull the second easy-open plate 242 to separate the top cover 2 and the bottom box 1.

[0027] The foregoing has shown and described the basic principles and main features of this invention, as well as its advantages. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications can be made to this invention without departing from its spirit and scope. All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
