Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of storage containers, in particular to a preservation box. BACKGROUND

[0002] Most of the preservation boxes on the current market have single structure and can only meet the sealing needs of single size containers. When users have different storage needs, such as storage of small amount of food materials and large amount of food materials, they need to prepare multiple preservation boxes of different specifications or place a small preservation box in a large preservation box during use. However, the existing preservation boxes are difficult to achieve stable sealing when the large and small box bodies are used in combination, and cannot take into account the sealing effect in the single use and combination use scenarios, which not only occupies space but also easily leads to food material leakage, poor preservation effect and inconvenience to users. CONTENT OF THE UTILITY MODEL

[0003] The present application aims to at least solve one of the technical problems existing in the prior art. To this end, the present application provides a preservation box which can improve the use flexibility and sealing performance.

[0004] In a first aspect, the present application provides a preservation box, comprising:

[0005] A first box body, a first protrusion is arranged circumferentially at an opening of the first box body;

[0006] A second box body, the second box body can be partially accommodated in the first box body, and a second protrusion is arranged circumferentially at an opening of the second box body, a lower surface of the second protrusion is provided with a contact structure, when the second box body is accommodated in the first box body, the lower surface of the contact structure abuts against the first protrusion, and a first spacing exists between the lowermost ends of the first protrusion and the second protrusion;

[0007] A cover body, a plurality of buckle assemblies are arranged circumferentially and spaced apart on the cover body, one side of each buckle assembly is respectively provided with a first clamping strip and a second clamping strip, a second spacing between the first clamping strip and the second clamping strip is equal to the first spacing, the first clamping strip is used for clamping the first protrusion, and the second clamping strip is used for clamping the first protrusion or the second protrusion.

[0008] The food storage container according to the first aspect of this application has at least the following beneficial effects: The food storage container utilizes a first protrusion at the opening of the first container body, a second protrusion at the opening of the second container body, and a snap-fit ​​assembly on the lid to cooperate. A first gap exists between the lowest points of the first and second protrusions, and a second gap exists between the first and second locking strips on the lid snap-fit ​​assembly, providing a foundation for the snap-fit ​​engagement. When the first container body is used alone, the first locking strip of the snap-fit ​​assembly does not participate in the snap-fit; only the second locking strip engages with the first protrusion. Through the tight engagement of a single locking strip with the protrusion, a stable sealing structure is formed, effectively preventing food leakage and the entry of outside air. When the second container body is placed inside the first container body for combined use, the first locking strip engages with the first protrusion, and the second locking strip engages with the second protrusion. The precise engagement of the protrusions and locking strips at different heights allows the lid to simultaneously fix both containers, preventing them from shaking and enhancing sealing performance and structural stability. The food storage container of this application improves the flexibility of use, meets different capacity storage needs, and saves space; at the same time, it can achieve tight fixation and improve sealing performance regardless of the method of use.

[0031] Most food storage containers on the market today have a simple structure and can only meet the sealing requirements of a single-sized container. When users have different storage needs, such as storing a small amount of food and storing a large amount of food, they need to prepare multiple food storage containers of different sizes, or place a small food storage container inside a large food storage container when using it. However, existing food storage containers cannot achieve a stable seal when using containers of different sizes together. They cannot achieve a good sealing effect in both individual and combined use scenarios. This not only takes up space, but also easily leads to food leakage and poor preservation effect, causing inconvenience to users.

[0032] Based on this, this application provides a food storage container to solve the aforementioned technical problems. The technical solutions provided by this application will be described in detail below.

[0033] Reference Figure 1 , Figures 3 to 6This application provides a food storage container, including: a first container body 100, a second container body 200, and a lid 300. The first container body 100 has a first protrusion 110 circumferentially disposed at its opening. The second container body 200 can be partially accommodated within the first container body 100, and has a second protrusion 210 circumferentially disposed at its opening. The lower surface of the second protrusion 210 has a contact structure, and when the second container body 200 is accommodated within the first container body 100, the lower surface of the contact structure abuts against the first protrusion 110. Furthermore, there is a first gap between the lowest ends of the first protrusion 110 and the second protrusion 210; the cover 300 is provided with a plurality of buckle components 320 at circumferential intervals, and a first buckle strip 330 and a second buckle strip 340 are respectively provided on one side of the buckle component 320. The second gap between the first buckle strip 330 and the second buckle strip 340 is equal to the first gap. The first buckle strip 330 is used to buckle the first protrusion 110, and the second buckle strip 340 is used to buckle the first protrusion 110 or the second protrusion 210.

[0034] The food storage container utilizes a first protrusion 110 at the opening of the first container body 100, a second protrusion 210 at the opening of the second container body 200, and a snap-fit ​​assembly 320 on the lid 300. A first gap exists between the lowermost ends of the first protrusion 110 and the second protrusion 210, and a second gap exists between the first locking strip 330 and the second locking strip 340 on the lid 300 snap-fit ​​assembly 320, providing the foundation for the snap-fit ​​engagement. When the first container body 100 is used alone, as... Figure 6 As shown, the first locking strip 330 of the snap-fit ​​assembly 320 does not participate in the snap-fit; only the second locking strip 340 snaps against the first protrusion 110. Through the tight engagement of a single locking strip with the protrusion, a stable sealing structure is formed, effectively preventing food leakage and the entry of outside air. When the second box 200 is housed within the first box 100 for combined use, as shown... Figure 4 As shown, the first locking strip 330 engages with the first protrusion 110, and the second locking strip 340 engages with the second protrusion 210. The precise engagement of the protrusions and locking strips at different heights ensures that the lid 300 simultaneously secures both containers, preventing them from shaking and enhancing sealing performance and structural stability. The food storage container of this application improves usability, meets different storage needs, and saves space; simultaneously, regardless of the usage method, it achieves a tight seal, improving sealing performance.

[0035] Reference Figures 1 to 3It is understood that the cover 300 is provided with mounting grooves spaced circumferentially. The snap-fit ​​assembly 320 includes a connecting rod 321 and a fixing plate 322. The fixing plate 322 is rotatably mounted on the connecting rod 321. The two ends of the connecting rod 321 are respectively set in the corresponding mounting grooves. The first locking strip 330 and the second locking strip 340 are set on the side surface of the fixing plate 322 near the first box 100 and the second box 200. The fixing plate 322 is rotatably mounted on the connecting rod 321, so that the fixing plate 322 can rotate about the connecting rod 321 as an axis. When it is necessary to snap the cover 300 to the box, the angle of the first locking strip 330 and the second locking strip 340 can be adjusted by rotating the fixing plate 322, so that they can better fit with the first protrusion 110 and the second protrusion 210. When using the first container 100 alone, the fixing plate 322 can be rotated to a suitable angle so that the second locking strip 340 accurately engages with the first protrusion 110. When used in combination, the fixing plate 322 is rotated so that the first locking strip 330 engages with the first protrusion 110 and the second locking strip 340 engages with the second protrusion 210. This rotatable latching assembly 320 makes it more convenient and faster for users to use the food storage container. By simply rotating the fixing plate 322, the locking strip can be accurately engaged with the protrusion, improving the convenience and efficiency of use.

[0036] Reference Figure 5 It is understandable that the fixing plate 322 has a gripping part 323 that is folded outward at the end away from the connecting rod 321. When it is necessary to rotate the fixing plate 322 to adjust the angle of the first locking strip 330 and the second locking strip 340, the user can pinch or hook the outwardly folded gripping part 323 with their fingers to apply a torque to make the fixing plate 322 rotate around the connecting rod 321, providing a force point for the user to pry open the fixing plate 322 and improving the user experience.

[0037] Understandably, the contact structure is the first seal 220. The first seal 220 is typically made of a material with elasticity and sealing properties. When the first container 100 and the second container 200 are combined, the first seal 220 is compressed between the two. The first seal 220 fits tightly against the contact surfaces of the first container 100 and the second container 200, thereby preventing air, moisture, and other impurities from entering the gap between them, forming a relatively sealed space and improving the airtightness of the food storage container.

[0038] Reference Figures 3 to 6It is understood that the lower surface of the lid 300 is provided with an annular groove, and a second sealing element 310 is provided in the annular groove. The second sealing element 310 is used to abut against the first protrusion 110 or the second protrusion 210. When the lid 300 is placed on the first box 100 or the combined first box 100 and second box 200, the second sealing element 310 in the annular groove on the lower surface of the lid 300 will contact and be compressed against the first protrusion 110 or the second protrusion 210. The second sealing element 310 is usually made of an elastic material. After being compressed, the second sealing element 310 undergoes elastic deformation, and the resulting elastic force makes it fit tightly against the surface of the first protrusion 110 or the second protrusion 210, thereby forming a sealing barrier between the lid 300 and the box, preventing air, moisture and other impurities from entering the box, and also preventing the contents of the box from leaking out, thereby improving the airtightness of the food storage box.

[0039] Reference Figure 3 and Figure 4 It is understandable that the openings of the first box 100 and the second box 200 are of equal size, and the diameter of the openings of the first box 100 and the second box 200 gradually decreases from the bottom direction. The interiors of the first box 100 and the second box 200 form a frustum shape that is larger at the top and smaller at the bottom, which can better accommodate the stacking and storage of objects, and also improves the smoothness of putting the second box 200 into the first box 100 and taking it out of the first box 100.

[0040] Reference Figures 1 to 3 It is understood that the openings of the first box 100 and the second box 200 are square, and the shape of the lid 300 matches the shape of the opening of the first box 100. Four latching components 320 are provided, and each of the four latching components 320 is respectively located on one of the four sides of the lid 300. With the lid 300 closed, by fastening the latching components 320 to the corresponding positions on the box, the elastic deformation and locking mechanism of the latches generate a tightening force, firmly fixing the lid 300 to the box. This ensures a tight connection between the lid 300 and the box at multiple points, preventing the lid 300 from accidentally falling off.

[0041] Reference Figure 2 and Figure 4 Understandably, the bottom of the first box 100 is provided with several support blocks 120. The support blocks 120 prevent the box from directly contacting the placement surface, avoiding scratches, wear, or even damage to the bottom of the box due to uneven placement surfaces or sharp objects. At the same time, during handling or placement, if there is any vibration or collision, the cushioning effect of the support blocks 120 can reduce the risk of damage to the items inside the box, thus better protecting the items inside the box.

[0042] ReferenceFigure 5 It is understood that the lower surfaces of the first protrusion 110 and the second protrusion 210 are respectively provided with a first anti-detachment block 111 and a second anti-detachment block 211, and the upper surfaces of the first locking strip 330 and the second locking strip 340 are respectively provided with a third anti-detachment block 331 and a fourth anti-detachment block 341. The third anti-detachment block 331 is used to engage with the first anti-detachment block 111, and the fourth anti-detachment block 341 is used to engage with the first anti-detachment block 111 or the second anti-detachment block 211. The first anti-detachment block 111 engages with the third anti-detachment block 331, and the fourth anti-detachment block 341 engages with either the first anti-detachment block 111 or the second anti-detachment block 211. Through this engagement method, the interlocking between the anti-detachment blocks restricts the movement of the first locking strip 330 and the second locking strip 340 relative to the first protrusion 110 and the second protrusion 210 in the horizontal and vertical directions, thereby ensuring the stability of the connection between the first box body 100 and the second box body 200 and improving the strength of the connection part.

[0043] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
