Technical Field

[0001] This utility model relates to the field of portable tableware technology, and in particular to a rotary sealing food preservation box. Background Technology

[0002] Food storage containers are widely used kitchen and dining utensils in daily life. Their main function is to keep food fresh, prevent moisture, and prevent cross-contamination of odors through a reliable sealing structure, while also making it convenient for users to carry when going out. Most food storage containers on the market use rotating lids or snap-on mechanisms to achieve a seal, which can meet the basic need for carrying food in a single container.

[0003] However, in real-world applications, users often need to carry multiple food containers simultaneously, such as preparing a weekday lunch containing staple foods, dishes, and soup, or preparing various foods for a family picnic. In such cases, users typically have to place these individual food containers one by one into a large tote bag or backpack. This results in the food containers being scattered and unrestrained within the bag, making them prone to collisions, tilting, or tipping over during walking or transportation. Even if a single food container is well-sealed, the violent shaking increases the risk of leakage, and it is also inconvenient to handle.

[0004] While existing technologies offer well-functioning individual airtight food storage containers, they generally lack structural designs that effectively integrate multiple independent containers. These products are physically isolated, lacking a locking and carrying mechanism to temporarily combine them into a stable, easily portable unit. This significantly reduces convenience and reliability when carrying multiple food items. Therefore, this invention proposes a rotary-sealing food storage container to address the shortcomings of existing technologies. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rotary sealing food storage box, which aims to improve the problem that some existing food storage boxes are scattered and inconvenient to retrieve when multiple boxes need to be carried.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Reference Figures 1 to 4 This utility model provides a rotary sealing food storage box, which aims to solve the problem that multiple storage boxes in the prior art are inconvenient to carry and lack an effective combination and locking structure.

[0022] like Figure 1As shown, the rotary sealing food storage container includes a storage container body 1 and a sealing cap 24 that is detachably threaded to the top of the storage container body 1. The upper part of the outer wall of the storage container body 1 is provided with a threaded groove 22, and the inner peripheral wall of the sealing cap 24 is provided with an internal thread that mates with the threaded groove 22. By rotating the sealing cap 24, it engages with the threaded groove 22 of the storage container body 1, thereby achieving a threaded connection between the two. The outer wall of the storage container body 1 is also integrally formed with multiple radially extending limiting posts 23.

[0023] It also includes a sealing mechanism 2 for locking multiple food storage containers 1, the sealing mechanism 2 mainly consisting of a perforated plate 26 and a force-applying plate 28; see reference Figure 3 The perforated plate 26 is a vertically arranged plate with multiple limiting holes 27 along its length. After stacking multiple food storage containers 1, the limiting holes 27 of the perforated plate 26 are aligned and fitted onto the outside of the limiting posts 23 on the outer wall of the food storage container 1, so that the perforated plate 26 can be detachably installed on the side of the food storage container 1 by means of plug-in engagement. The force plate 28 is a horizontally arranged rod that is detachably inserted through the upper part of the perforated plate 26. After being inserted, the force plate 28 can restrict the perforated plate 26 to the limiting posts 23, preventing the perforated plate 26 from detaching from the limiting posts 23. At the same time, the force plate 28 itself also serves as a handle for the user to hold.

[0024] Reference Figure 1 , Figure 2 and Figure 4 An annular mounting groove is provided at the top port of the food storage container 1, and a sealing ring 21 made of elastic silicone is embedded and fixed in the annular mounting groove. Correspondingly, a sealing block 29 is fixedly connected to the inner top wall of the sealing cover 24. When the sealing cover 24 is screwed onto the food storage container 1, the lower end face of the sealing block 29 abuts against the upper end face of the sealing ring 21 and produces elastic deformation. This compression fit fills any tiny gaps that may exist between the two.

[0025] Meanwhile, an exhaust assembly 25 is also provided on the top of the sealing cover 24. The exhaust assembly 25 includes an exhaust hole 251 opened on the sealing cover 24 and a sliding block 252 slidably connected to the top surface of the sealing cover 24. A plug for inserting the exhaust hole 251 is fixedly connected to the bottom of the sliding block 252. By sliding the sliding block 252 back and forth along the diameter direction of the top surface of the sealing cover 24, the plug at its bottom can be selectively inserted to close the exhaust hole 251 or disengaged to open the exhaust hole 251.

[0026] Reference Figure 1The bottom of the food storage container 1 is integrally formed with a downward recessed groove, the outline of which matches the top outer outline of the sealing lid 24; when stacking is required, the groove at the bottom of the upper food storage container 1 can directly engage with the top of the sealing lid 24 of the lower food storage container 1.

[0027] Reference Figure 1 and Figure 3 The length of the force-applying plate 28 is greater than the width of the perforated plate 26. After passing through the perforated plate 26, both ends of the force-applying plate 28 can extend out of the perforated plate 26. Furthermore, slots are provided on the outer peripheral walls of both ends of the force-applying plate 28 to prevent it from slipping out. The slots prevent the force-applying plate 28 from accidentally slipping out of the perforated plate 26 during carrying.

[0028] The upper part of the perforated plate 26 has a transverse through hole for the force-applying plate 28 to pass through; the limiting post 23 is designed as a cylinder extending radially from the outer wall of the food storage box 1, and the limiting hole 27 on the perforated plate 26 is a matching round hole. This pin-hole matching structure is simple and reliable in positioning.

[0029] The implementation principle of this application embodiment is as follows: When using a single food storage container, after placing the food into the food storage container body 1, align the sealing cover 24 with the threaded groove 22 on the top of the food storage container body 1 and rotate and tighten it. During the tightening process, the sealing block 29 on the inner wall of the sealing cover 24 will move downward and squeeze the sealing ring 21 on the top of the food storage container body 1 to form a reliable double seal. If the container contains hot food that needs to be vented, the sliding block 252 on the top of the sealing cover 24 can be slid first to open the vent 251. After the gas is released, it can be slid closed.

[0030] When multiple food storage containers need to be carried, firstly, the food storage container 1 is stacked by interlocking the top of the sealing lid 24 of the lower food storage container through the groove at its bottom; then, the perforated plate 26 is taken, and the limiting holes 27 on it are aligned one by one and inserted into the limiting post 23 on the side of each food storage container 1. Usually, the perforated plates 26 are symmetrically installed on both sides of the stack; finally, the force plate 28, which serves as a handle, is passed horizontally through the horizontal through hole at the top of the perforated plate 26. The insertion of the force plate 28 connects the perforated plates 26 on both sides, and through the cooperation between the limiting holes 27 and the limiting posts 23, all the stacked food storage containers 1 are firmly bound into a whole. The user can easily carry them by simply lifting the force plate 28.
